KEY TERMS Communis The expositional approach to the study of communication The rhetorical approach to the study of communication Claude Shannon, Warren Weaver, and Wilbur Schramm Sender Recipient Encoding Decoding Transmission Physical barriers to communication Linguistic barriers to communication Belief barriers to communication Stereotypes Informed generalizations SUMMARY An introductory communication text rightly begins by defining its core concept, communication. After defining communication and showing how it comes into existence, this chapter distinguishes different types of communication from each other. Communication derives from the Latin root word communis. In English, this root word means common, general, universal, or public. When a person believes, feels, values, or acts as one with another person, communis exists. Communication can be studied in two basic ways. The expositional approach studies attitudes, values, beliefs, feelings, or behaviors that unify people as a whole or particular groups of people. The...

...average calculations of S&N The goal is to increase the data rate (information flow) while decreasing band rate (better utilization of channel BW, cheaper links) Factors to consider in digital signaling: Long strings of 0‘s or 1‘s causes a drift of the obtained baseline, hence ―baseline wandering‖ that leads to incorrect bit decoding. 1) Baseline wandering: The receiver averages the signal power (Baseline), and uses it to decode the received signal bit value. 2) DC components: Constant level for long period of time creates very low frequency components in the frequency spectrum, that might not pass through some medium (e.g., TP of 200Hz 3000Hz). Hence, we need to remove the DC from the Digital Signal . 3) Self-Synchronization: To match the sender and receiver clocks, hence match the bit intervals at both ends for correct decoding. Transitions in the digital signal act as self-synch altering the receiver to the start, mid, or end of the bit, resetting its clock in case it is out of synch. 4) Built in error detection: It is good to add extra bits to the Tx data for error detection (and possibly correct). 5) Noise and interference immunity: Encoding/ Decoding complexity: complex - high cost Line Coding Schemes Figure 4.4 Line coding schemes 4.10 1) Unipolar: NRZ (non return to zero) No signal return to zero level at the mid of bit. Problem: Large DC component many low frequency components. Hence needs based...

...common structure of rhythmic patterns by all members of a culture. In today’s world it is an ever continuous process going on all the time, from simple conversations between friends to urgent business meetings among board members. Communication is used to convey information from one source to a receiver in order to get a desired response or action. In order for information to be received in the right way, it needs to be delivered and perceived the right way. This essay aims to show how effective communication is interdependent on the sender, receiver and the roles they play in executing effective communication by the use of the skills of encoding and decoding. This will be done by defining and describing key concepts. References will be made to credit the work in this essay through books, scholars and other valid sources of information. A summary of the whole essay will be made in conclusion with suggestions. Communication has been defined differently by various scholars and organizations. William Rice Johnson stated that, “Communication takes place when an individual, a sender displays, transmits or otherwise directs a set of symbols to another individual, a receiver with the aim of changing something , either something the receiver is doing(or not doing) or changing his or her world view. This set of symbols is typically described as a message.” Another definition can be given by Krist-Ashman, who says communication is “The exchange of information.” The two definitions all show...

...Because MPEG-1 & -2 are finalized standards and are both presently being utilized in a large number of applications, this case study concentrates on compression techniques relating only to these two standards. MPEG 3- it was originally anticipated that this standard would refer to HDTV applications, but it was found that minor extensions to the MPEG-2 standard would suffice for this higher bit-rate, higher resolution application, so work on a separate MPEG-3 standard was abandoned.

...COMMUNICATUION The term 'Communication' has been derived from the Latin word 'communis' that means 'common'. Thus 'to communicate' means 'to make common' or 'to make known'. This act of making common and known is carried out through exchange of thoughts, ideas or the like. The exchange of thoughts and ideas can be had by gestures, signs, signals, speech or writing. People are said to be in communication when they discuss some matter, or when they talk on telephone, or when they exchange information through letters. Basically, communication is sharing information, whether in writing or orally. The message, the medium by which the message/information is sent (e.g., written, oral, audio, visual), and the receiver or target of the communication information (decoder). Any disruption, garbling, malfunction, etc. at any point of that communication sequence could result in the failure of a successful communication. Any communication involves a particle which can be in one of four categories: an object. . . . . . a written message. . . . . . a spoken word. . . . . . or an idea. Any successful communication contains all the elements shown here. Any failure to communicate can be analyzed against these components to isolate what went wrong Benefits of Communication Communications Skills – The Importance of Removing Barriers: Communication barriers can pop-up at every stage of the communication process (which consists of sender, message, channel, receiver, feedback...

...time slots. Physical network coding allows A and B to transmit simultaneously reducing the total number of time slots to 2. This is a great idea to increase data transfer rates by minimizing the time slots and this way both the performance and the efficiency of the network is improved. All these reasons prompted me in selecting this particular project. The main aim of this project is basically to understand and implement both Straightforward Network Coding (SNC) and Physical network coding (PNC) in MATLAB. Having done that, the performance of the system in terms of bit error probability (BER) will be studied. Most importantly, the effect of imperfect synchronization between different streams on system performance will be investigated. In summary, the objectives of this project are outlined below: Understanding of fundamental theories underlying the concept of network coding. Developing MATLAB code to simulate SNC/PNC systems. Obtain and reflect the performance in terms of bit error probability (BER) and packet error probability (PER) Introduce the option for imperfect synchronization between received streams of different transmitters. Obtain, analyze and compare simulation results of the system BER and PER for the case of synchronous and asynchronous streams. Reflect on findings, identify trade-offs and recommend system network-coded configurations. Chapter 2.1 Introduction to fundamental theories In this section we are going to provide details about the network coding...

...Summary: Carol Teinchek & Bruce Marshall have first started Sundown Bakery. As the business grows, Carol hired two assistant to help her who is Marina from El Salvador and Kim a korean guy. Bruce also hired Maurice a French Canadian as a master baker in Sundown Bakery. Within the next year, two new shops and two kiosks stall have opened; Hans Mikelson was hired as a operation manager. Mikelson have implemented dress code for all employee and employee manual for new employee. All of these changes were announced in memo and distribute to employees. However, Mikelson’s memos have created some issues, experienced worker were furious about receiving orders from bureaucrats and new employee barely knew Bruce and Carol. Besides that, there are seven workers from different countries who now work together in original shop, which affect the quality of communication. Quality product alone is not enough to guarantee the continuing success of Sundown Bakery, they need to improve the quality of communication among the whole company. Question 1 . Communication is a process of transferring a message from one person to another. Effective communication is important when conducting a business; the receiver must able to interpret the meaning of the message correctly. The key element in communication process included sender, message, decoding, feedback, context and noise. The sender is the person who initiates the communication, his ideas or information is encoding into a massage in a form...

...S.Bhavani et. al. / (IJCSE) International Journal on Computer Science and Engineering Vol. 02, No. 05, 2010, 1429-1434 A Survey On Coding Algorithms In Medical Image Compression S.Bhavani Department of ECE Sri Shakthi Institute of Engineering & Technology Coimbatore, India Abstract— In medical imaging, lossy compression schemes are not used due to possible loss of useful clinical information and as operations like enhancement may lead to further degradations in the lossy compression. Hence there is a need for efficient lossless schemes for medical image data. Several lossless schemes based on linear prediction and interpolations have been proposed. Currently, context based approach has gained popularity since it can enhance the performance of above schemes due to the exploitation of correlation within the frame. Since the conception of Mesh based Compression from early 1990’s many algorithms has been proposed and the research literature on this topic has experienced a rapid growth which is hard to keep track of. This paper gives a brief description about the various coding algorithms and advancements in this field. Keywords- Image compression, prediction, medical image, context based modeling, object based coding, wavelet transform.

It is part of our everyday procedures when we work on any job to attempt to duplicate the problem prior to any maintenance taking place. Upon either not duplicating the problem or performing maintenance, the job gets signed off in the maintenance forms for the applicable aircraft and then on CAMS. CAMS is the computer program that keeps track of all maintenance that takes place on all of the aircraft on the flight line. Christian went out to the aircraft and duplicated the malfunction. He signed off the completed job in the aircraft forms, but failed to do so in the CAMS computer program. Mike had noticed that when he printed out a summary...
