The most obvious considerations that affect an organization's choice of security technologies are the threats the organization considers significant and the costeffectiveness of various security technologies against those threats. In practice, however, the choice is also strongly driven by less tangible, more nontechnical, considerations such as ease of implementation and maintenance, fit with ...

(LTE) present a number of design and verification challenges for system engineers. Some examples include determining design requirements and specifications for new hardware designs, evaluating hardware re-use, and testing RF/mixed-signal designs and hardware independently of baseband hardware. Electronic Design Automation (EDA) simulation tools can help address these challenges by enabling syst...

In practice, software engineers are only able to spend a limited amount of resources on statically analyzing their code. Such resources may refer to their available time or their tolerance for imprecision, and usually depend on when in their workflow a static analysis is run. To serve these different needs, we propose a technique that enables engineers to interactively bound a static analysis b...

In order to prepare students for careers as software process engineers, software engineering education needs to adopt innovative instructional designs to support effectively the learning of required knowledge and skills. In this paper, we propose a cross-course design for teaching software process improvement and assessment in a graduate course in combination with an undergraduate capstone proj...

Traditional libraries will evolve to digital libraries which are clearly superior at: Dissemination, sharing, linking, storing, and information variety. Therefore, one can say that electronic libraries have specific needs in terms of content, services and long-term preservation. In contrast, digital libraries suffer from several inherent constraints: storage limitation, performance, relevancy, ...

We propose a solution to the problem of system-level testing of functionally complex communication systems based on lightweight coordination. The enabling aspect is here the adoption of a coarse-grained approach to test design, which is central to the scalability of the overall testing environment. This induces an understandable modelling paradigm of system-wide test cases which is adequate for...

Human error is often related to flaws in system design which might have been avoided had greater attention been paid to human factors knowledge and methods as the system was developed. The paper considers the role of human factors in system design and argues that adopting an operational perspective in identifying human factors issues ensures that subsequent human factors advice is focused upon ...

Bacteria encounter fluctuations in both their external and internal environments, and to manage these conditions, they employ various control mechanisms. In this issue of Molecular Cell, Hart et al. (2011) investigate how E. coli robustly controls nitrogen assimilation.

1.0 INTRODUCTION Advancement in technologies such as sensing, electronics and computing have attracted tremendous research interest in the field of wireless sensors network (WSNs). Apart from their enormous potential for both the commercial and military applications wireless sensors network is generally consist of large number of low cost, low power multifunctional energy constrained sensors no...
