In spite of the tremendous privacy and liability benefits of anonymization, most shared data today is only pseudonymized. The reason is simple: there haven’t been any anonymization technologies that are general purpose, easy to use, and preserve data quality. This paper presents the design of Diffix, a new approach to database anonymization that promises to break new ground in the utility/priva...

State-of-the-art mobile computing environments must deal with scarce and dynamically varying resources-in particular, the network quality of service. Applications which execute in such environments need to adapt to the dynamic operating conditions in order to preserve the illusion of seamlessness for the end-user as far as possible. This paper proposes a framework for adaptation which provides ...

In this paper we show how software architectural styles can be used to guide object-oriented design. Design guidance is important as the initial phases of software design signiicantly impact software quality. We use two diierent architectural styles to guide the design process from a formal speciication to a design. Software architectural styles assist by providing a diierent level of reuse tha...

Electronic System Level (ESL) power estimation is executed in early design phases to avoid expensive redesigns. In this paper we concentrate on the evaluation of an existing ESL power estimation methodology for the modeling of future platforms, with respect to applicability, flexibility and reusability. Two industrial design cases are investigated. In the first one, an existing mobile communica...

Services based on packet switched networks are becoming dominant in telecommunication business and both operators and service providers must evolve in order to guarantee the required quality. Increasing bandwidth is no longer a viable solution because of the business erosion for network operators which cannot expect revenues due to the large investments required to satisfy new applications dema...

QoS assurance is a challenging task in unreliable networks. One of the reasons for unreliability in networks is the shortage of network resources under peak load conditions. Providing additional network resources is a possible solution for managing SLAs in unreliable networks. On demand market of bandwidth provides a good source for acquiring the necessary network resources from foreign network...

Pair comparison methods based on Case V of Thurstone’s Law of Comparative Judgment are widely used to derive interval scales for perceptual image quality. A thorough treatment of the involved statistical errors is often neglected, even though this is the base for computing confidence intervals and other statistical tests. In this paper we show, that consequent error estimation through all steps...

[Context & motivation] For market-driven software product developing organizations operating on a competitive open market, it is important to plan the product’s releases so that they can reach the market as early as possible with a competitive level of quality compared to its competitors’ products. Hence, quality requirements can be seen as a key competitive advantage. The QUPER model was devel...

Stroke contributes to the third leading cause of death in Malaysia and happens to be the prime cause of disability among Malaysian. Lack of awareness and knowledge of stroke among Malaysian have often led to delay in hospital administration and reduced the chances of recovery for stroke patients. The objectives of this research are three-fold: (1) To develop a mobile application that helps to p...

The study of the quality of electric power lines is usually known as Power Quality. Power quality problems are increasingly due to a proliferation of equipment that is sensitive and polluting at the same time. The detection and classification of the different disturbances which cause power quality problems is a difficult task which requires a high level of engineering knowledge. Thus, neural ne...
