REQUIREMENTS MODELING WITH UML
€ 49.00 *
ggf. zzgl. Versand

The Unified Modeling Language (UML) provides an environment for modeling complex systems. It supports a variety of diagrams for analyzing, designing, and implementing software systems. During the requirements phase, developers abstract concepts from the application domain and describe what the system is intended to do, not how it will do it. UML was adopted as a standard for OO modeling by the Object Management Group in 1997 and has found use in various software development projects. However, the continued success of any new technology depends a great deal on its usability. To predict the future success of a language like UML it is important to address the issue of usability from the perspective of the users of the language, the software developers. This publication reports on the results of an empirical study aimed at assessing the usability of UML for developing software requirements. It addresses the dimensions of ease of use, usefulness, and usefulness for communicating requirements to various project stakeholders.

RAID
€ 32.99 *
ggf. zzgl. Versand

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.RAID is an acronym first defined by David A. Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks, a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy. Marketers representing industry RAID manufacturers later reinvented the term to describe a redundant array of independent disks as a means of dissociating a ´´low cost´´ expectation from RAID technology.

Nella odierna società della conoscenza, l´innovazione tecnologica è uno dei principali fattori di sviluppo sociale, industriale ed economico. Lo sviluppo del Web come canale privilegiato di comunicazione e diffusione pone un accento particolare sulla transizione, sempre più accentuata ed evidente, dalla tradiziona-le formazione in aula alla formazione definita WBT (web based training), o più comunemente nota come FAD (formazione a distanza).

Decision Procedures
€ 52.99 *
ggf. zzgl. Versand

A decision procedure is an algorithm that, given a decision problem, terminates with a correct yes/no answer. Here, the authors focus on theories that are expressive enough to model real problems, but are still decidable. Specifically, the book concentrates on decision procedures for first-order theories that are commonly used in automated verification and reasoning, theorem-proving, compiler optimization and operations research. The techniques described in the book draw from fields such as graph theory and logic, and are routinely used in industry. The authors introduce the basic terminology of satisfiability modulo theories and then, in separate chapters, study decision procedures for each of the following theories: propositional logic; equalities and uninterpreted functions; linear arithmetic; bit vectors; arrays; pointer logic; and quantified formulas.

Applied Algorithms for Bioinformatics Problems
€ 41.99 *
ggf. zzgl. Versand

With significant growth of bio-molecular sequence data in the last decade the need for algorithms to extract patterns and meaningful information from such data has been felt strongly. Alignment of sequences, in order to determine regions of common descent, has also been an important area of research as it helps scientist discover the evolution of species. Another problem that researchers are putting in a lot of effort into, is document summary. As the lower bound for computation is being met for various algorithms, to further expedite the computing on large data sets, parallelization has become imperative. New multiprocessor architectures like the Cell Broadband Engine have the potential to do extensive calculations and act as mini-supercomputers. Other applications for these include onboard aircraft fault diagnosis and prognosis. We take a peek into some existing algorithms for these problems as well as propose novel algorithms along with their implementations to address these problems in the field of bioinformatics.

Modeling the Factors Affecting the Adoption of ...
€ 76.90 *
ggf. zzgl. Versand

Mobile commerce also known as M-commerce is thought to be the next big phase in technologically dependent society after following E-commerce era. This study aims to identify some factors that affect the adoption of M-commerce in Malaysia by developing M-commerce adoption Model based on exiting technology model such as, TRA, TPB, TAM and DOI. Structural Equation Modeling (SEM) is used to test the proposed model. The findings revealed that Perceived Usefulness, Perceived Ease of Use and Perceived trust are positively associated with consumer attitude towards use which is affecting consumer intention to use. PI and perceived cost were found to have insignificant effect on consumer attitude towards use. The findings made a contribution, allowing us to understand the factors that can affect the adoption of M-commerce. The findings have showed that the extended and modified model has good fit to the early adopter of M-commerce services and it explained 39 percent of the consumer´s intentions to adopt M-commerce services. The proposed M-commerce model has the potential to use as a basis for industry players´ evaluation of adoption potential of new M-commerce services.
