Web mashups are a new generation of applications based on the “composition” of ready-to-use services. In different contexts, ranging from the consumer Web to Enterprise systems, the potential of this new technology is to make users evolve from passive receivers of applications to actors actively involved in the “creation of innovation”. Enabling end users to self-define applications that satisf...

|We propose the new Group Metric (GM) decoder for convolutionally coded synchronous multiple-access channels. The GM decoder makes decoding decisions for one user, but incorporates multiuser information in its metrics. This decoder will have a reduced complexity which is exponential in the sum of encoder memory and the number of users. The soft-decision maximum-likelihood (ML) joint decoder can...

Transparency is a novel non-functional requirement for software systems. It is acclaimed to improve the quality of service since it gives users access to information concerning the system’s processes, clarifying who is responsible if something goes wrong. Thus, it is believed to support people’s right to a secure and private processing of their personal data. We define eight quality metrics for...

Current spectrum resources are lack due to inflexible spectrum sharing regulations and underutilization of licensed band for primary users (PUs). Cognitive radio (CR) technology is proposed to address this problem. CR technology enables secondary users (SUs) access temporally unused licensed spectrum in opportunistic manner. Benefit from high spectrum efficiency, CR technology has been widely u...

Modern information systems contain many mechanisms for implementing authorization and thus are capable of meeting a given authorization requirement with many designs. Each design carries a set of properties that directly impact users, such as administrative effort, risk of compromise, and flexibility. The property matrix method is a method to capture the user requirements for these properties, ...

We improve a secret sharing scheme, which enables users select their personal keys by themselves instead of being distributed by group manager and users can reuse their personal keys no matter the shared secret is renewed or recovered. Then we apply it to design a self-healing key distribution scheme. The new scheme achieves good properties. Firstly, the scheme reduces storage overhead of perso...

conclusions this study showed that mmt did not markedly alter the concentration of serum adiponectin in drug abusers. however, in regard to the variations in the serum lipid profiles and anthropometric parameters, the findings indicated that low concentrations of serum adiponectin might play a role in the pathogenesis of obesity and other metabolic abnormalities. thus, more long-term studies wi...

Non-Orthogonal Multiple-Access (NOMA)-based Multibeam Satellite Networks (MBSNs) are intended for 5G implementation, and networks set the requirement both high system capacity as well reliability to all users, which is achieved via system's fairness. The NOMA network requires a user grouping algorithm (UGA), most existing UGAs 2-users NOMA-MBSNs, favor maximization with little regard Thus, this...

background: anthropometry is a branch of ergonomics that considers the measurement and description of the human body dimensions. accordingly, equipment, environments, and workstations should be designed using user-centered design processes. anthropometric dimensions differ considerably across gender, race, ethnicity and age, taking into account ergonomic and anthropometric principles. the aim o...
