The functionality and efficiency of micro mobility schemes in wireless networks has a great impact on the overall performance of the whole network. In small cell wireless LAN environments, the network must support both frequent and numerous handovers at the same time. Together with providing fast and reliable handoffs, the micro mobility scheme must not affect the service perceived by users. Th...

This paper reports on an online survey eliciting effects of a decoy choice architecture for passwords. The survey measured preference for a given set of passwords and was conducted as a pre-study to a more interactive online-study to give us a feeling about the constraints of decoy passwords. The survey revealed that in some scenarios it is possible to influence the preference for a target pass...

Continuous time delta-sigma (CTDS) ADC is the architecture of choice for audio systems, for phone handsets and for mobile electronics. This ADC architecture allows efficient integration, signal chain reduction, low power consumption among other benefits. While CT DS ADCs outperform other classes of ADCs when high dynamic range and power efficiency are the primary requirements, other types of AD...

The problem this paper addresses is that an architecture formed of software components can contain composition errors (introduced, for instance, as a result of the choice of a framework’s parameters). The title “Erroneous architecture is a relative concept” is to emphasize that whether a composition error occurs in an architecture depends on the way the architecture is used in its environment. ...

A DSP engine for discrete wavelet transformation (DWT) is introduced in this paper. Serial processing DWT architecture provides a better speed and efficiency, makes DWT better choice for image processing than DCT. A dedicated hardware DWT architecture attached to a general purpose microprocessor provided the programmability of data access make possible for dynamic scheduling for various DSP app...

In large software systems, the achievement of qualities such as performance, availability, security, and modifiability is dependent not only upon code-level practices (e.g., language choice, detailed design, algorithms, data structures, and testing), but also upon the overall software architecture. Quality attributes of large systems can be highly constrained by a system’s software architecture...

Stemming from work by Buntine and Weigend (1991) and MacKay (1992), there is a growing interest in Bayesian analysis of Neural Network Models. We study computational approaches to the problem, suggesting an eecient Markov chain Monte Carlo scheme for inference and prediction with xed architecture feed forward neural networks. The scheme is then extended to the variable architecture case, provid...

Modern distributed software applications generally operate in complex and heterogeneous computing environments (like the World Wide Web). Different paradigms (client-server, mobility based, etc.) have been suggested and adopted to cope with the complexity of designing the software architecture of distributed applications for such environments, and deciding the "best" paradigm is a typical choic...
