Recent years in geographical information handling have been marked with constant change and innovation. Geographical information systems and enterprizes have continued to gravitate towards distributed models based on open systems technologies. Increasingly, successful geographical information markets are predicated on robust service infrastructures that offer guarantees on performance, availabi...

A revolutionary feature of emerging media services over the Internet is their ability to account for human perception during service delivery processes, which surely increases their popularity and incomes. In such a situation, it is necessary to understand the users’ perception, what should obviously be done using standardized subjective experiences. However, it is also important to develop art...

The Telecollaboration (TC) business system, an important class of emerging applications that is spawning new challenges to achieving the desired levels of performance. One important implication in identifying and characterizing the properties of TC system implementations is that performance evaluation should no longer be isolated and viewed as a separate analytic activity. Instead, we require a...

In this paper, we study the impact of low-quality node on the performance of incremental least mean square (ILMS) adaptive networks. Adaptive networks involve many nodes with adaptation and learning capabilities. Low-quality mode in the performance of a node in a practical sensor network is modeled by the observation of pure noise (its observation noise) that leads to an unreliable measurement....

Scalability is one of the most important quality attributes of today’s software systems. Yet, despite its importance, scalability in applications is poorly understood. This paper presents a model-based view of scalability in Web and other distributed applications that is aimed at removing some of the myth and mystery surrounding this important software quality. We review four models of scalabil...

In this paper, we propose a new statistical approach to investigate the performance of some objective quality metrics used in the literature in order to determine the most suitable quality metric for watermark transparency evaluation. To this end, we have defined a new procedure based on the ANOVA (ANalysis Of VAriance) tests and the subjective performance evaluation. Firstly, a set of selected...

Total Quality Management (TQM) has become a modern system of constant improvement the quality all company activities. This paper aimed conceptual compared multidimensionality total management and impact on performance based halal awareness. Based existing studies, we consider eight scopes include leadership, decision making, employee management, approach to supplier process customer focus conti...
