Serial Communication Over Parallel
Sachin Garg Indian Institute of Technology, Delhi-110016 E-mail:
 Abstract—Communication is the essence of today’s technologically advanced world. The two most basic methods of digital communication are: Serial and Parallel. Parallel communication involves multiple wires running parallel to each other and can transmit data on all the wires simultaneously. However, Serial communication requires a single wire for transferring data bits one at a time. A natural question arises out of human curiosity: which one of the two methods is better. This term paper discusses these two methods, their various applications and the advantages of the Serial Communication method over the Parallel one. Index Terms—Parallel Communication, Serial Communication UART, RS-232 DTE, Synchronous, Asynchronous.

Parallel counterpart have been resolved. Although the Parallel Transmission Method is still used within internal buses and for devices such as printers, but the latest devices, ports and technologies are mostly based on Serial Techniques. For example - Universal Serial Bus and WAN, both make use of the Serial Type Data Transmission.

II. TERMS USED IN DATA COMMUNICATION A. Transmission Distance The transmission distance of a communication signal is the length of path the signal travels as it goes from transmitter to the receiver. B. Data Terminal Equipment (DTE) Data Terminal Equipment (DTE) is a device or equipment that acts either as a source or as destination during the transmission of data signals. A DTE controls the communication channel. However, DTEs don‟t directly communicate with each other. For this purpose, the DTEs need Data Communication Equipment (DCE). Some examples of DTEs are: computer, printer, dumb terminals, file and application servers etc…...

Parallel Kinematic Machine

...1 INTRODUCTION 1.1 INTRODUCTION A parallel mechanism is a closed-loop mechanism of which the end-effector is connected to the base by a multitude of independent kinematic chains. Generally it comprises two platforms which are connected by joints or legs acting in parallel. In recent years, parallel kinematic mechanisms have attracted a lot of attention from the academic and industrial communities due to their potential applications not only as robot manipulators but also as machine tools. The dream of all developers in Machine Tools has always been to combine the flexibility and envelope of the robots with the accuracy and stiffness of traditional Machine Tools. In the last 20 years the focus of this development has been Parallel Kinematics Machines so called PKM. This technology means that the motions in X, Y and Z are performed by three or more parallel axis that gives an outstanding stiffness and accuracy with a maintained flexibility and envelope. Generally, the criteria used to compare the performance of traditional serial robots and parallel robots are the workspace, the ratio between the payload and the robot mass, accuracy, and dynamic behavior. In addition to the reduced coupling effect between joints, parallel robots bring the benefits of much higher payload-robot mass ratios, superior accuracy and greater stiffness; qualities which lead to better dynamic performance. The main drawback with parallel robots is the relatively small workspace. 1.2......

Serial Killers and the Media

...Serial Killers and the Media Maureen McCollom Kaplan University Deviance and Violence Professor Major March 26, 2013 Abstract Serial murders are not just part of the United States they also happen globally. There are many investigative tools that are used when working a serial murder case and we will discuss some of those. We will also discuss the problems with the media when it comes to serial murders. We will also talk about how the criticism of the public and media can affect serial murder cases. The crime of serial murder is not just one that in the United States it is a problem that happens globally. In the US we have the help of the Behavioral Analysis Unit as well as the FBI when working a case in any jurisdiction. To help law enforcement and investigators learn new techniques on how to solve these crimes a symposium was held for two days in 2008 to teach them new techniques. In attendance at this conference were mental health experts, scholars, media experts who have been studying serial murders for yeas and investigators in law enforcement field. The conference was held at INTERPOL headquarters, there were delegates from thirty-seven different countries in attendance at the conference. When working on a serial murder there needs to be more cooperation with other countries when working the cases. While most serial murders will stay within their comfort zone or home town, some will travel from place to place as well as out of the country to commit...

Laser Communication

... LASER COMMUNICATION SYSTEM (Light Amplification by Stimulated Emission of Radiation) Abstract: Laser communication is one of the key areas in wireless Communications. They work only under clear line-of-sight conditions between each unit, but they eliminate the need for securing right of ways, buried cable installations and no government licensing is necessary. Free space laser communications systems can be quickly deployed since they are small and do not need any radio interference calculations. Additionally, no spectrum fees have to be paid. This paper includes analysis, optimization, design and system level development of signal transformation between satellites or any two sources. Which work similarly to fibre optic links, except the beam is transmitted through free space. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed, one for transmission and one for reception. INTRUDUCTION: Laser Communication is one of the emerging areas of wireless communication system. Due to its low noise ratio makes its one of the well suited communication medium for exchange of information. Currently laser commutation is adopted in satellite communication for space research activities and due to its efficiency on low noise ratio, inexpensive, low power and its flexibility and its resistance to the radio interferences makes laser communication as one of research area in wireless communication. In this process, this paper...

...ABSTRACT The greed for money will make people commit Haynes crimes, for a 46 yr old Dutch women from the Netherlands was a motive to become a serial killer. Maria Catherina Swanenburg had love for money where she killed her parents, family members and other vulnerable people she cared for by poisoning with arsenic poison. Swanenburg was known as Vin der Linder by family and friends. She was a very affectionately given the nick name of “ Goeie Mie “ which means in Dutch “ Good Me “. She was given that nick name which she got by taking care of children and sick, fragile people in the neighborhood. Maria Catherina was born September 9, 1839 in the Netherlands. Swanenburg was the daughter of Clemens Swanenburg and Johanna Dingjon. It was speculated that after the deaths of her first two daughters she became heartless. Maria began her killing spree by poisoning her parents in 1880. She was able to keep their life insurance as well as the inheritance. However that opened up more greed for money. So she began poisoning the people she was caring for, she would mix the arsenic with the food or drinks of her victims. She would insure them and then poison them. Her rational was that she deserved to keep the inheritance as well as the life insurance money because she cared for these poor ill people. Swanenburg became bolder over time. The money she collected was just not enough for her. However she didn’t have a chance to spend any of the money because she continued to poison......

Serial Killers

...In the last three decades the USA has been troubled by an approaching problem, the serial killer. A serial killer is a person who kills a number of people, usually considered over five, with a cooling off period between each murder, usually one murder at one given time). Two murders at one time occasionally happen and these murders may go on for a period of months or years until the killer is caught. Throughout the last three decades the US serial killer rate has risen 94% and it is estimated that by the next millennium it will claim an average of 11 lives a day. Serial Murder is an epidemic; there are at least 35 serial killers active in the USA today who claim one third of the annual murder rate. The USA has 6% of the world's population yet it has three quarters of all serial killers. Not only are serial killers appearing in more numbers in the US but also all over the world countries are terrorized by serial killers, which are appearing in more numbers year and year after. KILLER TRAIT: A serial killer is a typical white male, 20-30, and most of them are usually in the USA. Their main motives are sex (even though the act of sex may or may not take place), power, manipulation, domination and control. The sex motive is usually rape for an organized killer and sadism for a disorganized killer. They act in a series of 5 or more murders with a cooling off period between each murder. Serial killers can go on for months and years before they are usually caught. The victim is......

Serial Killers

...I. Introduction Serial Killers are the group of people who kill, kill and kill over a longer period of time without being caught or stopped. Unlike mass murderers, who may kill many people at one time. Serial Killers are a different breed. Serial killers usually have reasons for killing, they just don't go out and kill anyone (the majority). A serial killer will plan out where, when, why, and how before they actually kill. Many enjoy cannibalism, necrophilia, and keep their trophy - like body parts as reminders of their work. There violent behavior is usually directed against women and children. In most cases, if a serial killer tortured his victims inhumanly than the killer himself has probably had a very disturbed childhood. II. Body ''I didn't want to hurt them,I only wanted to kill them.'' This is a quote from David Berkowitz the Son of Sam. David Berkowitz and all of the other serial killers tend to think in unique ways. Dahmer killed various ways and then hacked his victims into several pieces, dumping the bodies into vats of acid, and Gacy molested little boys before strangling them and dumping them into the crawl space under his home. They often tend to have interesting stories behind their killings because they often see and hear things that the normal person doesn't. Schizophrenia is a common source are associated with psychotics. As we examine childhood abuse as a possible key to the serial killer's behavior, we must remember that many children have suffered......

Dynamic Modelling of Parallel Manipulator

... “Newton Euler Strategy for the Dynamic Analysis of 3-DOF Parallel UPU Manipulator” Abstract This projects aims to describe the dynamic analysis of the 3-DOF Parallel UPU manipulator. The 3 DOF UPU is a parallel manipulator in which the U and P notations are for universal and prismatic pairs respectively, is a well-known manipulator that provides the platform with three degrees of freedom of pure translation, pure rotation or mixed translation and rotation with respect to the base, according to the relative directions of the revolute pair axes. The pure translational parallel 3-UPU manipulators have received a great lot of attention. Over the years many studies have been reported in the literature on the kinematic analysis, workspace optimization, singularities and joint clearance influence on the platform accuracy of this manipulator. However, the evaluation of the dynamic modelling of the parallel manipulators based on the two most famous methods i.e. Newton- Euler and Lagrange’s method have not been clearly discussed so far. Therefore, this project tries to throw light on this area and covers the Newton Euler Strategy for the calculation of the dynamic model of the 3 DOF UPU Parallel Manipulator. 1. Introduction Over the last few decades the parallel manipulators have attracted the attention of lot of researchers because of their complementary characteristic with serial manipulator. The word 'Parallel’ which is used here is to point out is not in the......

Serial Killers

...and death are twisted into a passion to kill. Otherwise a “typical” individual, serial killers turn to violence and death in search of power over others, and to explore their fatal addiction to their monstrous thrills. Most of society views serial killers as they are portrayed on television. There’s Dexter, the handsome serial killer who, while leading a normal life, takes it upon himself to rid all of the “bad guys” in the world in order to fulfill his need to kill. Then there’s Freddy Kruger, a disfigured dream stalker who uses a glove armed with razors to kill his victims in their dreams, causing their deaths in the waking world as well. Just to name a few others, there's also The Jigsaw Killer, Dr. Hannibal Lecter, Leatherface, Michael Meyers and the infamous Chucky. All of these characters are created to exaggerate something that is not only feared in movie theaters, but in real life as well. But what exactly makes a serial killer? While many of these movies and television programs try and make our minds believe that fiction is reality, there are no such things as ‘dream stalkers’ and talking dolls. A real-life serial killer can be distinguished (not by a scary masks) through the many distinctive patterns in their social and mental behavior, unusual childhood, murder periods, and Modus Operandi; all of which are fashioned in different ways to create a cold blooded murderer. Serial Killers are normally classified by their social and organizational skills.......

Business Communication Parallels in the Movie Pretty Woman

...Executive Summary This report seeks to explore communications at Republic Bank Trinidad Ltd. Communications would include internal(interdepartmental, intradepartmental, executive communication) and external. These communication would encompass formal and informal methods. Interdepartmental Communication Interdepartmental communication is very important to all organizations. Republic Bank Ltd as a bank would have to foster efficient communication as financial information need to be timely and accurate. On a daily basis information would need to be communicated across departments for the running of a bank. Information on a customer’s transactions may be requested by a loans officer. Communication would in most cases would be formal but some cases it would be informal and later documented to be formal. Intradepartmental Communication Within departments information needs to be shared so that departments do not have contradicting information. In the department managers would employ downward communication, through instructions, to employees while employees would engage in upward communication, through reports to managers. Formal communication would be most used through manager to employee relations. Whereas informal communication would more be conducted from employee to employee. Executive Communication Executive communication occurs when information from senior manager disseminates down the chain of command. Executive communication seeks to transfer senior management’s......

Parallel Journeys

...Book Review Parallel Journeys Parallel Journeys, by Eleanor Ayer with Helen Waterford and Alfons Heck, compares the life of two young people in Germany during the rise of Hitler and the outbreak of World War II. They were born within sixty miles of each other, but their lives took dramatically different paths. Alfons, is a boy who grew up on a farm in Germany. When Hitler came to power he became involved with the Hitler Youth. Alfons grew up on a farm but was a Nazi boy who became a commander at age sixteen. This book truly depicts Hitler's impact and influence on the youth of Germany. Alfons was brainwashed by Hitler's promises, a full pledged Nazi youth is how it is presented in the book he participated in all rallies. He started his training to become the future of Germany and eventually of the world. There he learned discipline and order. He trained to become a soldier and he learned the ways of warfare. He was taught to be a follower of anti-Semitism and was told to hate the Jewish people. He along with millions of Nazi’s believed that they were the reason for Germany's problems. As years went by, Alfons rose through the ranks of the military until the end of the war where realized what atrocities had been committed, he than took off his uniform and went on to help people. On the other side of the spectrum we have Helen Waterford a young Jewish girl who grew up in Frankfurt, Germany. She married Siegfried Wohlfarth and moved to Amsterdam because of tension......

Parallel Postulate

...Elliptic Geometry The parallel postulate (a.k.a. Euclid’s fifth postulate) in Euclidean Geometry states that if one cuts a line segment with 2 lines, and the interior angles add up to less than 180 degrees, then the two lines will eventually meet if extended infinitely (Euclid’s parallel postulate exact words: if a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles). Mathematicians such as Aristotle tried to prove this prove the parallel postulates, but they always ended up using the postulate itself in proving it, causing great controversies. In the late 19th century, mathematicians began to question if the postulate was true, which gave rise to the Non-Euclidean geometries. Elliptic geometry is a form of Non-Euclidean Geometry. It is different from Euclidean Geometry because it replaces the parallel postulate with the statement, "through any point in the plane, there exist no lines parallel to a given line” (there are basically no parallel lines), and because it modifies Euclid’s second postulate (there are no infinate lines in elliptical geometry). Bernard Riemmannian, the man who founded Elliptical (a.k.a. Riemmanian Geometry) Geometry had a lecture in 1854 discussing the ideas currently called manifolds, Riemmanian metric, and curvature. He also made many Non-Euclidean......

Serial Killers

...Serial Killer Psychology By Anna Davis Criminal psychology refers to the study of the mental and behavioral characteristics of people who break laws established by local, state, national or international governments. Some criminal, or forensic, psychologists focus their research on serial killers -- men and women who murder a large number of people over an extended period of time — typically months or years. What constitutes a serial killer is open to interpretation. In the United States, Congress has defined a serial killer as someone who murders a minimum of three or more people. By definition, a cooling-off period separates the murders, making them appear random or unconnected. The victims — often prostitutes, runaways or other vulnerable populations — rarely know their killer and may serve as a symbol that triggers the attack. In other words, a serial killer's motive tends to be psychological, not material. Understanding what goes on — or gets turned off — in a serial killer's mind is the ultimate goal of scientists who specialize in this area of psychology. You might think the field is relatively new, but it dates back to at least the 19th century, when psychologists tried to develop a profile of the mysterious and elusive Jack the Ripper. Antisocial Personality Disorder vs. Psychopathy Mental health professionals use the Diagnostic and Statistical Manual of Mental Disorders (DSM), developed by the American Psychiatric Association, to understand the......
