Formal methods of generating and specifying requirements have a chequered past when it comes to dealing with interface design. The Human Computer Interface (HCI) community have not adopted formal methods with open arms [Paterno 96]. If the accurate determination of stakeholder requirements is a significant factor in determining software project success, this thesis turns to a theory based in psychology and sociology to understand these capricious actors, the misunderstanding of whose whims can bring down 70% of software projects. This thesis will deploy Activity Theory as a basis for a proposed system design method and present initial conceptions and some …

Box-Minus Operation And Application In Sum-Product Algorithm, S Tong, P Wang, D Wang, X Wang
Faculty of Engineering and Information Sciences - Papers: Part A
A new formula for box-minus operation, which separates the box-minus operation into sign and reliability operations, was derived. Its application in the sum-product algorithm (SPA) was also investigated. Both box-plus operation and box-minus operation were divided into sign operation and reliability operation. The results show that on using the box-minus operation, SPA can be implemented with less decoding latency and complexity.
