The Function of Place and Space in Days of Heaven by Terence Malick

The Function of Place and Space in Days of Heaven by Terence Malick Film theory deals with the exploration of the nature and essence of films, their influence on the audience, relationships of the film context and scenes with reality, society, its history and culture. Films use specific â€Å"means of expression†, such as camera work, lightning, shots, sound.Advertising We will write a custom essay sample on The Function of Place and Space in â€Å"Days of Heaven† by Terence Malick specifically for you for only $16.05 $11/page Learn More Place and space are ones of the most influential means of expression that are used to render the changes of time, plot of the films and historical context. They are extremely important for the understanding of the theme and message of the film, and create specific form of it. Moreover, they influence the intellectual and emotional processes of viewing a film. In this paper, we are going to discuss the function of place and space in Days of Heaven by Terence Malick produced in 1 978. Place and space are skillfully used in the film and contribute greatly to the understanding of the film and its main characters. The settings of the Days of Haven are the Texas of the early 20th century. The film tells the story of two lovers, Abby and Bill who came there to find better living. The story develops in the picturesque landscape of the crop fields, woods and beautiful rivers. The film is considered to be landmark of the American cinema and it is widely recognized as one of the best films of the 1970s American cinema. The director made use of the powerful symbolism of nature which shaped the scenes of the film, its dialogues and plot. One of the most significant features of the film is that all major events and scenes are developing in the specific landscapes. The choice of landscapes is not accidental. They contribute to the audience’s perception of the scenes and shape their meaning. The film Days of Haven can be considered a revolutionary in the use of suc h expressive means as time and space. Almost every minute, the screen is filled with beautiful, startling images of the open crop fields. There are many panoramic close-ups of the open landscapes and waving fields. These images influence on the understanding of the characters of the protagonists of the film very much. It seems, as if they are losing their individualities; their needs and motifs are miniaturized comparing to the vivid landscapes of the Texas. Thus, in the film, â€Å"the project of deploying space as an analytical tool involves consideration of a number of different aspects of space† (Thomas 1).Advertising Looking for essay on art and design? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the most inspiring scenes of the film is the episode of the â€Å"Golden Hour† from the Cricket and Fire scene. In is one of the most beautiful pictures one can see during the film. It is very symbolic as encom passes the transition from the first act of the film to the second and embodies the change that should happen in lives of the protagonists. The use of space in this scene has a great meaning. First of all, it shows that person has no power over the nature and, at the same time, he is a part of it. Thus, the Days of Haven is truly one of the most beautiful films of the American cinema. It is notable for the extraordinary usage of the space and place. These expressive means contribute greatly to the development of the plot and influence the perception of the film by the audience. Thomas, Deborah.

113 Perfect Persuasive Essay Topics for Any Assignment

3 Perfect Persuasive Essay Topics for Any Assignment SAT / ACT Prep Online Guides and Tips Do you need to write a persuasive essay but aren’t sure what topic to focus on? Were you thrilled when your teacher said you could write about whatever you wanted but are now overwhelmed by the possibilities? We’re here to help! Read on for a list of 3 top-notch persuasive essay topics, organized into ten categories. To help get you started, we also discuss what a persuasive essay is, how to choose a great topic, and what tips to keep in mind as you write your persuasive essay. What Is a Persuasive Essay? In a persuasive essay, you attempt to convince readers to agree with your point of view on an argument. For example, an essay analyzing changes in Italian art during the Renaissance wouldn’t be a persuasive essay, because there’s no argument, but an essay where you argue that Italian art reached its peak during the Renaissance would be a persuasive essay because you’re trying to get your audience to agree with your viewpoint. Persuasive and argumentative essays both try to convince readers to agree with the author, but the two essay types have key differences. Argumentative essays show a more balanced view of the issue and discuss both sides. Persuasive essays focus more heavily on the side the author agrees with. They also often include more of the author’s opinion than argumentative essays, which tend to use only facts and data to support their argument. All persuasive essays have the following: Introduction: Introduces the topic, explains why it’s important, and ends with the thesis. Thesis: A sentence that sums up what the essay be discussing and what your stance on the issue is. Reasons you believe your side of the argument: Why do you support the side you do? Typically each main point will have its own body paragraph. Evidence supporting your argument: Facts or examples to back up your main points. Even though your opinion is allowed in persuasive essays more than most other essays, having concrete examples will make a stronger argument than relying on your opinion alone. Conclusion: Restatement of thesis, summary of main points, and a recap of why the issue is important. What Makes a Good Persuasive Essay Topic? Theoretically, you could write a persuasive essay about any subject under the sun, but that doesn’t necessarily mean you should. Certain topics are easier to write a strong persuasive essay on, and below are tips to follow when deciding what you should write about. It’s a Topic You Care About Obviously, it’s possible to write an essay about a topic you find completely boring. You’ve probably done it! However, if possible, it’s always better to choose a topic that you care about and are interested in. When this is the case, you’ll find doing the research more enjoyable, writing the essay easier, and your writing will likely be better because you’ll be more passionate about and informed on the topic. You Have Enough Evidence to Support Your Argument Just being passionate about a subject isn’t enough to make it a good persuasive essay topic, though. You need to make sure your argument is complex enough to have at least two potential sides to root for, and you need to be able to back up your side with evidence and examples. Even though persuasive essays allow your opinion to feature more than many other essays, you still need concrete evidence to back up your claims, or you’ll end up with a weak essay. For example, you may passionately believe that mint chocolate chip ice cream is the best ice cream flavor (I agree!), but could you really write an entire essay on this? What would be your reasons for believing mint chocolate chip is the best (besides the fact that it’s delicious)? How would you support your belief? Have enough studies been done on preferred ice cream flavors to support an entire essay? When choosing a persuasive essay idea, you want to find the right balance between something you care about (so you can write well on it) and something the rest of the world cares about (so you can reference evidence to strengthen your position). It’s a Manageable Topic Bigger isn’t always better, especially with essay topics. While it may seem like a great idea to choose a huge, complex topic to write about, you’ll likely struggle to sift through all the information and different sides of the issue and winnow them down to one streamlined essay. For example, choosing to write an essay about how WWII impacted American life more than WWI wouldn’t be a great idea because you’d need to analyze all the impacts of both the wars in numerous areas of American life. It’d be a huge undertaking. A better idea would be to choose one impact on American life the wars had (such as changes in female employment) and focus on that. Doing so will make researching and writing your persuasive essay much more feasible. List of 3 Good Persuasive Essay Topics Below are over 100 persuasive essay ideas, organized into ten categories. When you find an idea that piques your interest, you’ll choose one side of it to argue for in your essay. For example, if you choose the topic, â€Å"should fracking be legal?† you’d decide whether you believe fracking should be legal or illegal, then you’d write an essay arguing all the reasons why your audience should agree with you.

Follow the three tips below to create a top-notch essay. Do Your Research Your argument will fall apart if you don’t fully understand the issue you’re discussing or you overlook an important piece of it. Readers won’t be convinced by someone who doesn’t know the subject, and you likely won’t persuade any of them to begin supporting your viewpoint. Before you begin writing a single word of your essay, research your topic thoroughly. Study different sources, learn about the different sides of the argument, ask anyone who’s an expert on the topic what their opinion is, etc. You might be tempted to start writing right away, but by doing your research, you’ll make the writing process much easier when the time comes. Make Your Thesis Perfect Your thesis is the most important sentence in your persuasive essay. Just by reading that single sentence, your audience should know exactly what topic you’ll be discussing and where you stand on the issue. You want your thesis to be crystal clear and to accurately set up the rest of your essay. Asking classmates or your teacher to look it over before you begin writing the rest of your essay can be a big help if you’re not entirely confident in your thesis. Consider the Other Side You’ll spend most of your essay focusing on your side of the argument since that’s what you want readers to come away believing. However, don’t think that means you can ignore other sides of the issue. In your essay, be sure to discuss the other side’s argument, as well as why you believe this view is weak or untrue. Researching all the different viewpoints and including them in your essay will increase the quality of your writing by making your essay more complete and nuanced. Summary: Persuasive Essay Ideas Good persuasive essay topics can be difficult to come up with, but in this guide we’ve created a list of 3 excellent essay topics for you to browse. The best persuasive essay ideas will be those that you are interested in, have enough evidence to support your argument, and aren’t too complicated to be summarized in an essay.

The Idea of Realism Essay Example | Topics and Well Written Essays - 1000 words

The Idea of Realism - Essay Example The essay "The Idea of Realism" will examine the idea of realism in the context of modern art. Realism is an artistic movement that was popular in France. In attempting to ‘accurately’ reflect life in all its objective detail, artists taking a Realist approach often worked to find the most ‘common’ people of the fields and villages and depicted them in their most humble and menial tasks. The ideas behind realism can be better understood by comparing the writing of two influential artists of the period, Gustave Courbet and Ferdnand Leger. Gustave Courbet held that â€Å"painting is an essentially concrete art and can only consist in the representation of real and existing things†. The chief technical concern of Courbet seemed to be an abandonment, to some extent, of the ‘rules’ of art in favor of a more natural flow of line and form. By retaining these rough elements of the painting, Courbet felt he was more accurately representing the mom ent and the emotion of the moment during which the piece was created or the scene was witnessed. As he continued to attempt to portray the ‘real’ of life by focusing upon the humble peasantry, he began to identify himself more and more from their perspective. By 1850, his ideas regarding what was real were becoming more defined as he wrote to a friend, â€Å"†¦ in our so very civilized society it is necessary for me to live the life of a savage. I must be free even of governments. The people have my sympathies, I must address myself to them directly†.

Challenging Current Boundaries & Perceptions of Emergency Care Essay

Challenging Current Boundaries & Perceptions of Emergency Care - Essay Example The researcher of this proofreading analyzes the article, that discusses on the implications that shift work, particularly night work, has on nursing and the well being of individuals as well as patient care. It gives practical advice about how to cope with night shifts and also gives suggestions on the ways of improving health and well being. All of these could be examined and proven as to how it could be implemented in an emergency care setting. However, they do not detail the ways to cope with the turnaround from nights to days, the legal requirements in relation to the above, the health and safety issues associated with shift work and with nurse’s health. In addition, it is stated that patients safety has been poorly explored. They have also failed to investigate the effectiveness of set shift patterns whether they are permanent night staff or set pattern of rotation. While the article title could mislead one to believe that it deals with both night and day shifts, the art icle, however, is centred on night shift work only. Shift work is defined as a period of work performed outside the normal spread of working hours, particularly in a factory or business that operates on a 24 hour basis. Nurses, in general, are expected to work a period of night duty and be able to demonstrate an understanding of patient experiences of health care 24hours a day and seven days a week, but there is contradiction with this, that was analyzed in Challenging Current Boundaries & Perceptions of Emergency Care paper in detail.

Design A 1 Bit Serial Adder Computer Science Essay

Design A 1 Bit Serial Adder Computer Science Essay The main aim of this project is to design a 1-bit serial adder, simulate its functionality and obtain a layout on silicon, using the 0.35 µ process from AMS. The circuit designed shows a working serial adder clocking at (100MHz of nsecs) with a delay of 0.56910nsec. The area of the layout is 99.3016.35  µm2 in this technology. The circuit performs an 8-bit addition in 0.569108 nsesc. The circuit uses a standard 1-bit full adder and it has a feedback loop using a D-flip-flop in order to transmit the carry bit to the next input value. The final layout product has 3-input pads and 2-output pads, with power and ground pads. The process known as serial addition of binary numbers is well known in the computing and units capable of performing such serial binary addition ordinarily comprise a basic portion of more complex computation devices. In the past, such serial adders for binary numbers have employed vacuum tube circuitry for the most part and have accordingly been subject to the disadvantages that they are relatively in large size, fragile in configuration and are subject to operating failures. These factors raise serious questions of disposition of components and problems of maintenance. The present invention serves to obviate the foregoing difficulties and in essence provides a serial adder structure capable of performing full addition of binary numbers. It is accordingly an object of the present invention to provide an improved serial adder for use in computing applications. An object of the present invention resides in the provision of an improved serial adder for binary digital applications employing magnetic amplifiers as components thereof. Another object of the present invention is the provision of the serial adder for binary numbers which adders can be made in relatively smaller sizes. A still further object of the present invention resides in the provision of a computation device comprising, in combination, a plurality of magnetic amplifiers and a plurality of gating devices so interconnected with one another that the mathematical process known as a serial bit addition. The binary adder of the present invention includes provision for selective coupling the input train pulses to be added as well as carry pulses produced by the device itself to the plurality of gates, and the gates are adapted by themselves to selectively pass signal pulses required for the operation or inhibition of the plurality of magnetic amplifiers mentioned above. In digital s ystems, digital signal processing and control systems we can control it when we are able to count. Addition is the fundamental operation for all these systems. The fastness and accuracy are highly influenced by the adders we are use for the circuit design. Adders are very important components in the digital components because of their extensive use in digital operations such as multiplication, subtraction and division. The execution of binary operations inside a circuit would be greatly advanced by improving the performance of the digital adders. The main aim of designing the bit serial adder is to Perform one bit at a time, using the first bit operation results to influence the processing of subsequent bits. It reduces the amount of hardware required as it passes all the bits in the same logic. However this approach needs 1/nth part of hardware when compared to the n-bit parallel adders. As we are using 1-bit instead of n-bits its structure reduces the signal routing and performs at high speed as we are using 1bit register for the temporary storage and one full adder rather than an n-bit adder. The reduction in the price of the logic results in taking n clock cycles to execute this serial hardware, whereas parallel hardware executes in one clock cycle. This bit structure deals with the bit stream hence this have been successfully used in many applications like digital systems, digital signal processing, control systems etc. It was extremely popular in 2-5u technology range. The performance of a digital circuit block is gauged by analysing its power dissipation, layout area and its operating speed. The main aim of this project is to design a 1-bit serial adder. Through this project research we get the knowledge of working behaviour and performance of the 1-bit serial adder. Adders are the basic components for the designing of any digital circuit. Adders are very important components in the digital components because of their extensive use in digital operations such as multiplication, subtraction and division. The execution of binary operations inside a circuit would be greatly advanced by improving the performance of the digital adders. The main aim of designing the bit serial adder is to perform one bit at a time, using the first bit operation results to influence the processing of subsequent bits. Here in this case the one bit serial adder is designed by using a flip-flop and full adder. . This circuit has two stages full adder stage for the addition of two bits that are entered serially and second stage is flip-flop stage which temporarily stores the carry until the next stage is processed. The temporary storage of the carry in the flip-flop depends on the clock pulse. Its design principle shows how the two inputs entered serially. These two inputs will be added by the full adder along with the carry which was temporarily stored by the flip-flop and gives us the sum output and carry output. The normal 1-bit serial adder uses the XOR gates from the available core library. But in this XOR gate there is an OR gate which usually reduces the performance of the XOR gate. Hence the circuit has been modified by designing the XOR gate by using the NAND gates. What we would like to do now is find the easy way to use the sub tractor along with the serial adder circuit. By using this sub tractor we can subtract the lower bit value from higher value. This binary sub tractor has been added to one of the input which we are thinking to subtract the value. In our serial adder circuit the sub tractor is attached to the one of the inputs Y which is usually a XOR gate. This results in the subtraction of Y value from higher bit values. BACKGROUND 2.1 Addition: Addition is a process of adding bits. Binary addition means adding binary bits 0s and 1s and sum and carry generated in binary farm in any signal processing. Now lets consider the 4-bit addition example, As shown above A and B bits added giving Sum out by rippling the carry at each stage and C4 as final carry obtained. 2.2 Subtraction: Subtraction is a process of adding a positive bit to the negative bit. Negative of a bit means 2s compliment of it. This is nothing but adding 1 bit to LSB of its 1s compliment. 1s compliment is nothing but reversing the logic of the bits. Now lets consider the 4-bit subtraction example, The above subtraction technique dedicated to the subtracting a smaller binary from a larger binary. If it changes it just followed by few more steps as change sign bit (MSB) to zero, then change it to its 2s compliment as before process. Metal-Oxide-Silicon Field-Effect transistors (Mosfets) NMOS Transistor Here is a diagram of nmos transistor The source and drain are connected to the two blobs of n-type semiconductor material. The gate is on top, separated (and electrically insulated) from the rest of the transistor by a thin layer of silicon dioxide (same material as sand doesnt conduct at all). The source and drain are separated by p-type material. This forms two diodes pointed in opposite directions (when you have n-type next to p-type material, you get a diode), so no current can flow between the source and drain. When a high voltage (higher than the voltage level of the source, which is defined as the lower voltage of the two end terminals) is applied to the gate, it puts a positive charge on the gate. This attracts a negative charge in the region underneath the gate (opposite charges attract), forming a channel of negative charge carriers or an n-channel between the source and drain, which allows current to flow. So the nMOS transistor conducts when the gate is raised to the high voltage level, which we consider to be the logic level for 1 (true). PMOS TRANSISTOR The pMOS transistor is the dual of the nMOS transistor. You can look at the same diagram, but swap every n and p, and every + and -. Now, when the voltage at the gate is lower than the source (the higher voltage of the two end terminals for a pMOS transistor), we end up with a negative charge on the gate, which induces a positive channel underneath the gate, which allows current to flow. So the pMOS transistor conducts when the gate voltage is low, which we consider to be the logic level for 0 (false). The full names of what is being described are enhancement mode n-channel or p-channel metal-oxide semiconductor field effect transistors (MOSFET). Enhancement mode refers to the fact that we have to create the channel by applying voltage to the gate. (There are also depletion mode transistors that have a channel built in to start with.) Field effect refers to the fact that were using the electric field from the charge at the gate to control things. Metal-oxide semiconductor refers to the fact that were using an oxide to insulate the gate from the rest of the transistor. The two types of transistors are named for the channel: nMOS has an n-channel; pMOS has a p-channel. Cmos There are many ways to make logic gates (not to be confused with the gate of the transistor) out of transistors. What Im showing here is the dominant way that gates are done in digital electronics today, but there are many variations out there. This is called static CMOS logic. Static refers to the fact that there are not clocks involved. CMOS stands for complementary metal-oxide semiconductor. The complementary means we have both nMOS and pMOS transistors. The intuition behind this design style is simple. First, you dont want to have nMOS and pMOS transistors mixed up close to each other, because they need to be created on different types of substrate. So the natural style is to have a bunch of nMOS transistors together that pull the output one way for certain input values, and a bunch of pMOS transistors together that pull the output the other direction for the other input values. It turns out to work better to have the nMOS transistors pull down toward logic 0 and the pMOS transistors pull up toward logic 1. This is both for electrical reasons (nMOS conducts 0 better; pMOS conducts 1 better) and also to make it easy to get inverting gates. The following diagram showing how to make an inverter (a NOT gate): Such that we developed CMOS Technology by combination of Pull-up network of PMOS Transistors and Pull-down network of NMOS Transistors. All the CMOS gates are constructed using as shown below. CMOS Constructed by, PMOS transistors in Pull-up network stage and NMOS transistors in Pull-down network stage. OUTPUT going 1->0   The Pull-down NMOS transistors discharges the output capacitance. OUTPUT going 0->1 The output capacitance is charged through Pull-up PMOS transistors. MOSFETs transition states in CMOS Transistor: CMOS logic is better logic than PMOS and NMOS implementations individually. Because PMOS transistors are great at transmitting a logic 0 to1 voltage without signal loss, NMOS transistors are great at transmitting a logic 1 to 0 voltage. 4.2 NAND GATE: Constructed by, As shown below PMOS transistors in parallel and NMOS transistors in series.

Circuit diagram of NOR Gate: Logic symbol of NOR Gate: Truth table of NOR Gate: XOR GATE: XOR is also called Exclusive OR gate or EOR gate. This is a digital logic gate, which is used to express the function of Exclusive Disjunction. Its behavior is similar to or gate with exclusive condition. Usually it is a 2-1 input output IC respectively. An output HIGH (1) will be resulted if one, and only one of its 2 inputs is HIGH (1). Result of output LOW (0) both the inputs should be same either low or high. We can say EX-OR gate as One or another, but not both. XOR gate is used to develop a binary addition. It gives the sum for given input bits. As shown above xor of 2 bits A and B gives its sum. A xor B = A.B + A.B Circuit diagram of xor gate: BASIC ADDER UNIT Addition of two binary numbers is the most basic arithmetic operation i.e. two bits. A combinational circuit which can add only two bits is known as half adder. A full adder is one that adds more than two bits i.e. three bits. Full adder uses two adders in its implementation. In this study full adder is the basic addition employed in all adders. HALF ADDER Half is a basic adder circuit that can perform addition of two bits and gives the output of sum and carry. Half adder circuit uses an Exclusive-OR and AND gates for sum and carry outputs. XOR gate gives the sum output and carry output is given by the AND gate. X and Y are inputs S is sum and C0 is carry. S = X.Y + X.Y = X Ġ¦ Y C = X.YIts schematic representation is as shown in the figure. The truth table of half adder is as shown below. X Y SUM C0 0 0 0 0 0 1 1 0 1 0 1 0 1 1 0 1 K-MAPPING of half adder circuit is given as shown below. Sum, S = X Ġ¦ Y Carry, C0 = X.Y FULL-ADDER Full adder can be formed by combining two half-adder circuits followed by the OR gate. It can perform the addition of three bits along with the carry input given as output from the previous one. The difference between half adder and full adder is that half adder cannot count more than two bits and cannot add the carry input which will be possible in full adder circuit. In this circuit, sum output is given by the XOR gate and the carry output is given by the AND gate followed by the OR gate. The block diagram of full adder circuit is as shown below. FULLADDER Sum S = X Ġ¦ Y Ġ¦ CI = (X Ġ¦ Y) Ġ¦ CI Carry C0 = (X .Y) + (X Ġ¦ Y).CI As shown in the above figure X, Y and CI are the adder inputs. The truth table of the above circuit is as shown below.

RS flip flop is the fundamental building block for the D- flip flop. It has only one data input. That is connected to the input S of RS flip flop where as D is inversely connected to the R input.. D- Flip flop is also having second input for holding the data which is known as Enable, simply represented as EN. The enable input is AND-ed with the D- Flip flop. D- Flip flop holds the data according to the clock pulse. It is constructed by using AND gates and NOR gates as shown in the below figure. D and EN are the inputs and Q and Q are outputs. The block diagram of the D-flip flop is as shown below. D- Flip flop acts as temporary data storage in the 1- bit serial adder. Its storage capacity depends on the number of stages. The storage capacity of the D- flip flop in this serial adder is the total number bits (0 and 1) of digital data it can retain. Its truth table is a shown below. D EN Q QN 0 Falling edge 0 X 0 Rising edge 0 1 1 Falling edge Qprev X 1 Rising edge 1 0 . The wave forms are attached in the results. CHAPTER 2 SERIAL ADDER The process known as serial addition of binary numbers is well known in the digital and units capable of performing such serial binary addition ordinarily comprise a basic portion of more complex computation devices. In the past, such serial adders for binary numbers have employed vacuum tube circuitry for the most part and have accordingly been subject to the disadvantages that they are relatively in large size, fragile in configuration and are subject to operating failures. These factors raise serious questions of disposition of components and problems of maintenance. The present invention serves to obviate the foregoing difficulties and in essence provides a serial adder structure capable of performing full addition of binary numbers. It is accordingly an object of the present invention to provide an improved serial adder for use in digital systems. The main aim of designing the bit serial adder is to perform one bit at a time, using the first bit operation results to influence the processing of subsequent bits. Here in this case the one bit serial adder is designed by using a D-flip flop and full adder. . This circuit has two stages full adder stage for the addition of two bits that are entered serially and second stage is D-flip flop stage which temporarily stores the carry until the next stage is processed. The temporary storage of the carry in the D-flip flop depends on the clock pulse. Its design principle shows how the two inputs entered serially. These two inputs will be added by the full adder along with the carry which was temporarily stored by the flip-flop and gives us the sum output and carry output. This is a practical serial adder that is used to add a stream of two bits addition. First it takes the Least Significant Bits (LSB) in addition. Its block diagram is as shown in the figure. As shown in the above figure the inputs Xi and Yi are serially entered into the full adder along with the temporary carry from the D-flip flop i.e. Ci and gives the carry output Ci+1 and sum output Si. Hence serial adder is simple and because of feedback looping bit delays are expected. It can be constructed with very low cost and it is the perfect adder at low speed operations. Si = Ci Ġ¦ Yi Ġ¦ Xi Ci + 1 = Yi . Ci + Xi . Ci + Xi . Yi = Ci . (Xi Ġ¦ Yi) + Xi . Yi The above equations represent the Sum and Carry outputs using Boolean equations. The construction of 1-bit serial adder is as shown in the figure. As shown in the figure the inputs X and Y are serially entered through the full adder along with the carry input which was the feedback output of full adder. In this circuit, sum output is given by the XOR gate and the carry output is given by the AND gate followed by the OR gate. D- Flip flop used in this circuit acts as a temporary storage of carry.

Chapter 3 Nand gate design of serial adder: 4.4 NAND gate is BETTER THAN NOR. As PMOS in parallel and NMOS in series the resultant transition delay at NAND gate is lesser than delay of NOR gate architecture. To make PMOS as fast as NMOS we need enlarge channel and P-regions, but that leads to large silicon layout, and more cost and power wastage. So At same speed NOR is always larger than NAND. So it makes NAND more efficient than NOR. W/L ratio of NAND gate is smaller than NOR gate. If inputs for gates are more then, NAND will be very faster than NOR. So we use sop implementation rather than pos. XOR GATE USING NAND GATES In PMOS holes flow very slowly when compared to the electrons in the NMOS technology. Hence NMOS is faster than PMOS transistor. In NOR gate PMOS transistors are connected in series and in NAND gate PMOS transistors are connected in parallel hence NAND gate is faster than the NOR gate. Now considering another case to make this one bit serial adder little bit faster compared to the normal one bit serial adder the XOR gate is constructed by using the NAND gates which works faster than the normal XOR gate. The reason for constructing this XOR gate is that in the core library we are using to design the entire circuit XOR gate internally contains an OR gate which usually reduces the performance of XOR gate. Its circuit diagram is as follows. X Y OUT 0 0 0 0 1 1 1 0 1 1 1 0Its truth table is as shown below. D- Flip Flop using nand gates: D Flip-Flop is the most popular Flip-Flop. As its output takes the value of data ( D ) input when the positive edge of clock pulse. D Flip-flop can be interpreted as a primitive memory cell. D Flip-flops are basically used as Shift registers. As a D Flip-flop can produce a output signal with a time period delay of given clock pulse for an input signal i.e., one bit shifted right to the input given signal. The principle of D flip-flop is it captures the signal at the moment the clock goes high, and subsequent changes of the data lines do not influence Q until the rise of next clock edge. thus it works as a edge triggering mode at clock signal rising. D Flip-flop is constructed using NAND gates as shown above, where D and CLOCK are the inputs and Q and QN are the out puts.

It is only logical to assume that the same circuit can also perform the binary subtraction. If we look at the possibilities involved in subtracting one bit number from another, we can quickly see that three of the four possible combinations are easy and straight forward. The fourth one involves a bit more. 0 0 = 0 1 0 = 1 1 1 = 0 0 1 = 1, with a borrow bit. That borrow bit is just like a borrow in decimal subtraction: it subtracts from the next higher order of magnitude in the overall number. The truth table of this sub tractor circuit looks like as shown below. This is an interesting result. The difference, X-Y, is still an exclusive-OR function, just as the sum for addition. The borrow is still an AND function, but is XY instead of XY. Adder/Subtractor logic developed using NAND gate (lower from higher): Addition is adding positive two bits. Subtraction is nothing but an addition where we add one positive bit to another negative bit. That means the second bit will be the positive number with negative polarity. We can convert positive binary to negative binary by its 2s compliment. 2s compliment is nothing but adding 1 bit to the LSB side of 1s compliment. 1s compliment is in any binary code if we swap bits by 1 bit with 0 bit and 0 bit with 1 bit. That is flip the binary code image. 1s compliment can be generated using XOR logic. when we give one pin of XOR gate dedicated to positive as logic 1, and other pin connected to the input binary bit, then output of EXOR will be swapped by 1s with 0s and 0s with 1s. At the same time other advantage is if the dedicated input pin is given logic, then out put will be same as input binary code. Such that in that whole circuit by changing selective pin as 0 logic it works as adder and by changing selective pin as 1 logic it works as subtractors 1s compliment input. Let we consider A + B it is a simple addition, For A B = A + (- B) = A + (B 1s compliment + 1) = A + B 1s compliment + 1 As shown above to find A B we give the full adder inputs as a to A, b to B 1s compliment and finally c in as positive logic 1. Thus adding 2 bits of A And B in this way we get A- B. Above developed subtractor circuit subtracts lower value bit from higher value bit so in 0-1 condition its not valid.

The required logic gates and flip flop has been taken from the core library. Once taking all the required components from the core library wiring has been done again using the core library. One wiring has been done the sheet has been saved and done the schematic check. Once the schematic check has been done successfully then the view point has been created. Once view point has been done successfully the circuit has been run for simulation. After having done the simulation successfully the output waveforms has been checked. This output waveforms results the working of the entire circuit design. Once we got the outputs exactly what we are looking for we then go for layout design. This layout design is also done by using the core library which is known as silicon layout. After finishing the layout we will check the overflow of the IC which we will get at the en d of the process. Conclusion: In the project of One Bit Serial Adder we obtained the knowledge about the functionality of adders and developed a fast adder using NAND gate Logic. We even obtain the knowledge about CMOS technology and functionality of IC Gates. As we developed using NAND gate logic implementation the architecture of IC will be much faster and efficient. From the obtained results of Serial adder waveforms and IC design by comparing the theoretical and practical values are verified each other. Such that I can conclude the developed ICs are well functioning in any application era with a delay of 0.5921ns. Finally I concluded that a 1-bit Serial adder is developed in Conventional, NAND gate architecture and Adder/Subtractor architectures IC design and layout of IC design obtained and verified without errors. Functional and Electric Characteristics studied similar to CMOS technology as they developed.

Assessment of Developmental Stages of a Child

The significance of milestones Milestones are usually grouped together in five major areas which are to be assessed during the growth and development of a child. They are: physical growth, cognitive development, language development, and sensory and motor development. The assessment of the physical development of a child is very important during the growth and development of a child from infancy to adolescence and also the later years, it helps in that it allows the parents of the child as well as health care workers to see if there are any abnormalities in the child during this period of time.The assessment of the cognitive development of the child is also very important in order to detect if the child has any difficulties in learning, grasping and understanding concepts such as dyslexia. Social and emotional development should also be assessed in order to see how well the child can interact with peers and other persons in order to determine if the child has or will have a phobia in the later years of his or her development.The study was conducted in the presence of a nine year old child where in all the following areas of development were observed physical development, cognitive development, and social and emotional development. The reason why this specific age was selected was because it would have provided more opportunity for the researcher to observe and assess the different areas of development vastly and on a wider scale. Letters were sent to the parents of the child explaining the reason of the research and the different areas that were being observed.The researcher presented herself in a modest way so that the child would feel a sense of comfort while under observation. The study was conducted over a four day period where the following findings were observed. Day One On day one the area of focus was physical development. The writer started out by assessing Amanda (not her real name) who is nine years old, she weighs ninety pounds and measures 4feet 9i nches. Being that she is nine years old, she has passed the some of her milestones which includes sitting up and rolling over.The researcher also asked the parents of the child other questions such as; at what age did she start creeping? At what age did she start creeping? At what age she began sitting up on her own? Among a host of other questions pertaining to her growth and development physically. This was to find out if the child had any physical disabilities during her earlier stages of growing and developing. The writer further went on to investigate how much the child could follow instructions. As a result the child was then asked to get dressed both formally and informally.The instructions were followed accordingly. She was able to dress herself properly; this allowed the researcher to see how well the child can follow instructions when given. She is able to understand, analyze and follow the directions when given. After looking at how the child followed instructions in rega rds to getting dressed, the researcher went on to observe how the child manipulated objects. This was done by placing the child in an area where different types of objects were present. She was able to differentiate between shapes and the objects that were present.Jigsaw puzzles were solved, shapes were recognized and the child was able to identify other objects in and around the play area. This indicated that the child while at play displayed great sensory motor skills and can use them effectively; she also seems to be well alert and has a great sense of humor she also seems to deal with different types of situations how they ought to be dealt with. Day Two On day two the researcher’s main area of focus was on cognitive development, this area of focus is mainly linked to Piaget’s theory of cognitive development.Jean Piaget’s theory of cognitive development focuses on four stages. They are: sensory motor, pre operations, concrete operations and formal operations . Piaget observed that cognitive development refers to changes that occur in an individual’s cognitive structure, ability to process from childhood to adulthood. Piaget went on to state that at this stage (concrete operations 7-11), the child should be able to; conceptualize effectively, solve problems easily and create logics based on his or her cognitive experiences.The child observed was able to have discussions on a more logical basis and gave positive responses. The child was able to sit with the researcher and have discussions about her life as a little girl. She was asked different questions such as; what she would like to become in the future? How big would she like her house to be? What type of car would she like to own? Among others, she gave positive responses and seems to be well prepared for her future.She gave response such as; â€Å"I would like to become a doctor and have my own business running different from my career such as a super market or a toy store f or little kids, I would also like to own a three story house with two Toyota motor vehicles and my house is going to be surrounded by some big pit bull dogs and will be under twenty four hour security protection†. The researcher noted how effective the child was able to use the English language. She speaks the English Language fluently for a child her age.Many factors though is said to have contributed to this as the mother recalls that during her pregnancy, she read a lot. The child is provided with the proper printed resources and education friendly. The child is also provided with games that will enhance her memory she has both printed and electronically inclined games to enhance her memory. This type of environment enables her to gain the knowledge and necessary skills required to be able to: 1) reason effectively, 2) solve problems effectively, 3)explore the environment. 4) have a good memory.The child was always corrected whenever she makes a mistake. Hence, the child ha s a full advantage of how to speak English language as to Creole which is dominant in her community. In Piaget’s theory of cognitive development the child has passed the first two stages which are sensory motor (stage one) and pre operations (stage two). The child is presently at the concrete operations which she is almost completed all the activities that are to be done at this stage effectively. Day Three and Four The area of focus on days three and four were social and emotional development.Social and emotional development is a very important aspect of development in a child’s life. It is normally harder to pinpoint than other signs of development such as physical development. This area emphasizes many skills that increase self-awareness and self-regulation The researcher observed the child while she was interacting with some of her friends that came over to her house, since this was the most convenient to the researcher as well as to the child. Based on the observa tions the child seems to have communicated well and had no difficulty responding and interacting with her peers.At play the child seemed to be enthused and played well with her friends. She seemed to be the leader of everything they did in their peer group and was always quick to correct her friends whenever any of them made any mistakes. This is a clear indication that Amanda has no difficulties when interacting with her peers, and also seem to have pleasure during interaction with others. During meal time, the researcher had the opportunity to sit with the family for a few minutes to observe Amanda at meal time.She seems to have good etiquettes and knows how to conduct herself when she is around the table and was correcting her smaller sister when she did not conform to the table rules. She was also sharing with her parents what her teacher taught her at school about do’s and don’ts while sitting around the table at meal time. She was able to maneuver the knife and f ork properly and she was enthused in sharing some of the family traditions and norms that were passed down to her by her family with the researcher she also gave her view point on them when asked.She seems to have good communicating skills and enjoys interaction with her peers, family and also with others. When interacting with her friend she explained to them that she does not like to be shouted at also whenever her mother talks to her in a rough manner he goes to sit by herself and appears to be sad. Whenever her father comes in from work she normally runs to him and gives him a big hug. This shows that the child is emotionally attached to her parents.

Franz Kafka, in his novella â€Å"The Metamorphosis†, and Harry Mulisch, in his novel The Assault, uses dark, lonely diction and imagery to create the isolation within the protagonists. The setting symbolizes how the protagonist’s isolation continues to enlarge throughout the book. At the beginning of both the novels, the setting is more open and light, which is compared to the characters’ isolation that is less bordered and complex. As the settings grow smaller and the characters become lonelier, Anton and Gregor’s isolation become more pronounced. Gregor is gradually becoming isolated by his family causing his transformation to progress rapidly, while Anton’s family is growing, but his isolation is conflicted upon himself, causing the setting†¦show more content†¦Similarly, the setting in The Assault also expressed Anton’s isolation as he moved from city to city, but is trapped within his own self-conscious as the memories of his past gradually keeps coming back to him as he tries to keep a normal life. At the beginning of the novel, Anton is taken away from his family by Nazis who have invaded their home, causing the base of Anton’s isolation. After Anton is taken from his home, he is sent to a jail where he meets a mysterious woman. As he recalls his past events with the woman, he is starting to shut down his ability to share his memories with other people, comparing to the setting that shows â€Å"darkness filled [with] black water† (Mulisch 32), representing the beginning of Anton’s isolation.
