Distributed cryptographic computing system plays an important role in cryptographic research since cryptographic computing is extremely computation sensitive. There are many research results done in this aspect, but no general cryptographic computing environment is available for cryptographic researchers and engineers. Grid technology can give an efficient computational support for cryptographi...

Since the xDSL specifications impose stringent linearity requirements to ensure the integrity of the data transferred, current line drivers use linear amplifiers. The downside of these solutions is their power consumption, as the xDSL modulation has a high peak to average ratio, forcing the amplifier to operate in its least efficient region. An alternative is the use of switching amplifiers, wh...

The requirements of industrial applications only rarely permit the exclusive use of single paradigms in the development of real-time systems. Product cost, reuse of existing solutions, and efficiency require diverse, or even opposing methods to coexist or to be integrated. In this paper, we deal with one problem encountered during the development of a real-time system for motion control in auto...

In this paper an unusual taxonomy for optical mappings is introduced based on their geometric characteristics: 1. type of projection center (single viewpoint, non single viewpoint) and 2. type of transformation (projective, non projective). Under this background we survey the multi media geometry (refraction resulting from different optical media). Strict physical models of non projective mappi...

An active orthosis was designed to support users with reduced muscle strength with an additional knee joint torque to improve the independency in everyday activities. In two persons the hypothesis was tested that less muscle activity is necessary when standing up with the active support of a motorized orthosis. The orthosis is a custom-made knee-ankle-foot orthosis and is equipped with a series...

OBJECTIVE To study prevalence of depression in poststroke survivors in Phramongkutklao Hospital and factors associated with depression. MATERIAL AND METHOD From 150 stroke survivors, therefor 101 patients who met inclusion criteria. These subjects were screened with Thai Geriatric Depressive Scale (TGDS) and interviewed. Demographic data that would effect depression were evaluated. RESULTS ...

The automatic determination of defects in business process model and the assurance of a high quality standard are crucial to achieve easy to read and understandable models. Recent research has focused its efforts on the analysis of structural properties of business process models. This paper instead wants to focus on the labels and their impact on the understandability and integratability of pr...

To describe the structure of a system, the UML Class Diagram yields the means-of-choice. Therefor, the Class Diagram provides concepts like class, attribute, operation, association, generalization, aggregation, enumeration, etc. When students are introduced to this diagram, they often have to solve exercises where texts in natural language are given and they have to model the described systems....

The breeding of crocodilians is still a recent activity in Brazil. Its peak was in the 1990's, but it has gaps in its production, as there are no norms for the commercial breeding of these animals in captivity. However, its economic potential is great, and the search for ecological balance and viability of commercial production has become a challenge among farmers of this activity. Therefor, th...

Asynchronous Transfer Mode (ATM) inherits the feature of sharing cell losses and transmission delays among all virtual connections across a physical link. Therefor, delayand losssensitive real-time traffic needs special treatment when applications communicate via ATM. Some issues are looked at in this paper. Introduction Existing communication networks will be replaced by integrated networks wh...
