Managing heat is a major challenge to meet future demands for a sustainable use of our energy resources. This requires materials, which can be custom-designed to exhibit specific temperature-dependent thermal transport properties to become integrated into thermal switches, transistors, or diodes. Common crystalline and amorphous materials are not suitable, owing to their gradual changes of the ...

In order to ensure a secure data life cycle, it is necessary to delete sensitive data in a forensic secure way. Current state of the art in common database systems is not to provide secure deletion at all. There exist academic demonstrators that address some aspects of secure deletion. However, they are limited to their deletion approach. We argue, due to different data sensitivity levels (prob...

Buckypaper are self-supporting films of carbon nanotubes (CNT), which can be used as electrodes, nano filter or for the reinforcement of polymers, for instance. Usually they are produced by filtration of CNT dispersions. The disadvantages of filtration process are discontinuous operation, long duration of filtration and limited size of the buckypaper. The aim of this project was to develop a sp...

We introduce a new framework for constructing tests of a general semiparametric hypotheses which (i) have non-trivial power on the n−1/2 scale in every direction. (ii) can be tailored to put substantial power on alternatives of importance. The approach is based on combining test statistics based on stochastic processes of score statistics with bootstrap critical values.

This article examines the potential of application profiles and domain profiles as means to adapt technical specifications of data structures to particular needs. The authors argue that application profiling is better suited to increase the use of formal specifications than the creation of new specifications. The authors also describe a method to generate specific conformance test systems for m...

Functions which control the access to data in groupware should be flexibly designed by offering different options to the end users. However, conflicts might arise among different end users in the process of selecting one of these options. To support users in finding a consentaneous solution for these conflicts, we propose a metafunction called "negotiability". We propose to define and explore t...

This paper presents the Pure/Epos approach to deal with the high complexity of adaptable operating systems and also to diminish the distance between application and operating system. A system designed according to the proposed methodology may be automatically tailored to satisfy an specific application. In order to enable this, the application must be written referring to the inflated interface...

We propose to create tailor-made application servers by composing components providing support for individual non-functional properties. In this position paper we start from a static, asymmetric approach splitting the application server in two parts to support realtime properties and generalize this to a symmetric, componentized architecture. We then analyse how modelling of nonfunctional prope...

understanding the opinions of major role players in education (i.e. teachers, students, and policy makers) on all aspects of learning and teaching is influential to the success of the educational process. the purpose of this study was to investigate efl (english as a foreign language) teachers' views on measuring reading comprehension. a cohort of 50 iranian efl teachers teaching at university,...
