Coding Theory Patrick C Davis MTH/221 24 Nov 2014 Gerald Weyand University of Phoenix Coding Theory Case Study When representing‚ manipulating‚ and transmitting information‚ it is crucial to use the sequence of zeros and ones. However‚ it is often impossible and difficult to prevent errors especially in retrieving‚ operating‚ transmitting and storing any form of data. Errors occur from different sources‚ for instance‚ human beings‚ equipment‚ and communication and electrical interference. In most

Coding Theory Case Study Alicia Griffin MTH 221 June 9‚ 2014 Howard Thomas Coding Theory Case Study What is Coding Theory? “Coding theory is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression‚ cryptography‚ error-correction and more recently also for network coding. Codes are studied by various scientific disciplines – such as information theory‚ electrical engineering‚ mathematics‚ and computer science – for the purpose of designing

Theories of Knowledge and Psychological Applications Robin A. Finlayson University of Saskatchewan Ed.Psy: 855.3: Advanced Educational Psychology October 16‚ 1996 How individuals are able to obtain knowledge is something that psychologists have studied for a number of years. The ability to store and retrieve knowledge provides individuals with the propensity to form logical thought‚ express emotions and internalize the world around them. In order for a psychologist to

Recall of concrete and abstract word pairs: a study of word concreteness effect Abstract This experiment studied the effects of concreteness of unrelated noun pairs on free recall. Paivio’s Dual Coding Theory suggests that memory can encode information in verbal or non-verbal forms‚ depending on the format of the information‚ and word concreteness has additive effect on memory performance. This experiment explored whether concrete words are better recalled than abstract words. The design was

Second‚ the first practical applications of Fountain Codes‚ LT codes are treated. Last but not least‚ based on LT codes and a pre-coding scheme so called Raptor Codes are presented with some record-breaking properties. I. INTRODUCTION The Binary Erasure Channel (BEC) is a channel model where the receiver either receives the transmitted bit or is informed with the erasure of the
