Ehlers-Danlos syndrome (EDS) is a heterogenous group of inherited disorders of connective tissue characterized by fragility of the skin and blood vessels, hyperextensibility of the skin and joint hypermobility. Cutis laxa is characteized clinically by lax, pendulous skin and histologically by loss of elastic tissue in the dermis. There are some reports of coexistence of cutis laxa with ot...

The development of heterogenous catalysts using renewable materials has received wide attention. A catalyst been a preferred choice as it evades the disadvantages homogeneous catalysts, nevertheless, limited activity and longer separation process. current study emphasises preparation new magnetic oil palm empty fruit bunch (EFB) fibre carbon-based support material. effect different alkaline pre...

The current study focused on the heterogenous catalytic hydrothermal liquefaction (HTL) of Brachychiton populneus biomass seed, using Ni as hydrogenation catalyst and Fe active hydrogen producer. activity metal Ni/Al2O3 in HTL seed (BS) a mixture shell (BM) was studied. To establish best operating process conditions, influence variation temperature reaction time product yields also examined. hi...

Production of 1,2-propanediol and 1,3-propanediol are identified as methods to reduce glycerol oversupply. Hence, hydrogenolysis is a thermochemical conversion substitute; however, it requires an expensive, high-pressure pure hydrogen supply. Studies have been performed on other potential processes whereby aqueous phase reforming has excellent substitute for the process due its low temperature ...

In this chapter, we consider the problem of system-level design where subsystems are diverse. As a concrete example, consider an embedded system with the architecture shown in figure 1 (after [5]). The subsystems are implemented in both hardware and software, making this architecture a suitable candidate for hardware/software co-design. But even within the software portions, there is diversity....

Uncertainty sampling methods iteratively request class labels for training instances whose classes are uncertain despite the previous labeled instances. These methods can greatly reduce the number of instances that an expert need label. One problem with this approach is that the classifier best suited for an application may be too expensive to train or use during the selection of instances. We ...

Integrated access to information that is spread over multiple, distributed, and heterogeneous sources is an important problem in many scienti c and commercial domains. While much work has been done on query processing and choosing plans under cost criteria, very little is known about the important problem of incorporating the information quality aspect into query planning. In this paper we desc...

One crucial aspect of information technology for e-Society is security, where authorization is one of the three important factors, besides availability and integrity. During the past years Role-Based Access Control (RBAC) has been proven a sound method of modeling the authorization within an organization. Recently we introduced a novel distributed concept RBAC which is based on distributed gene...

A large part of today’s information retrieval studies focuses on modeling user search behavior to improve search algorithms, evaluate their quality and simulate users. Most of previous research on user modeling considers homogeneous search environments, where search devices, users, their search tasks and corresponding search results are assumed to be uniform. However, real-world search environm...
