AvBandTest – a Testing Tool for Implementations of Available Band width Estimation Algorithms

This work describes a test tool that allows to make performance tests of different end-to-end available bandwidth estimation algorithms along with their different implementations. The goal of such tests is to find the best-performing algorithm and its implementation and use it in congestion control mechanism for high-performance reliable transport protocols. The main idea of this paper is to describe the options which provide available bandwidth estimation mechanism for highspeed data transport protocols and to develop basic functionality of such test tool with which it will be possible to manage entities of test application on all involved testing hosts, aided by some middleware.

Application of Fuzzy Variables for Systems of Management Decision Support

The following article describes an approach covering the variety of opinions and uncertainties of estimates within the chosen technique of decision support. Mathematical operations used for assessment of options are traced to operations of working with functions that are used for assessment of possible options of decision-making. Approach proposed could be used within any technique of decision support based on elementary mathematical operations. In this article the above-mentioned approach is described under analytical hierarchy process.

Die Notwendigkeit von Unterstützungsangeboten für Geschwister von chronisch kranken und/ oder behinderten Kindern : eine retrospektive Einschätzung der Betroffenen

Introduction: It is a big challenge that devolopes in a family with the birth ofdisabled or handycapped child. The siblings of the disabled or handicapped child aredealt with issues like sufferings, sickness, weakness and even death. Furthermorethey have to take part in assisting and care of the disabled or challenged child. Theexperience they make as they grow up with a disabled or handycapped sibling is aburden more than a challenge lies on the support service options they are entitled.The choices are from the representatives of social organisations to professional help.Aim of this work is to analyse the necessity of support services for the siblings of thedisabled or handycapped child. To achieve this, a retrospective analysis of the peoplewho were affected by such a situation is necessary.Material and Methods: Structured, guidelined, problem centered personnalinterviews with affected siblings. The method was chosen against the background ofadequate affected siblings with necessary informations, knowledge and experience.Nine interviewees were selected and requested for cooperation per e-mail. FourInterviews were done personnally and five through telephone.Result: All the interviewees had disabled or handicapped or diseased siblings. Someof the interviewees knew there was something not in order with thier sibling beforethier preschool age. Some of them noticed thier siblings as "different" through theinteractions with other schoolmates. All the interviewees except the ones who werementally challenged siblings were well informed by their parents about the situation.The limitations of the siblings were very complex. The interviewees had a lot oflimitations and obligations for themselves because of the disability of their siblings.All but one of the interviewees could atleast think of one nice experience with thiermentally or physically challenged sibling. There was also negative experiences withanxiety, anger and rag

Modernisierung der Wärmeversorgung von zwei Liegenschaften der SWG Tangerhütte GmbH in Grieben und Tangerhütte

In this work, energy concepts for two completely different properties are sought. The first property is a deconstruction of an apartment building with 26 residential units on two separate buildings with 6 residential units. The energy concepts should enable an energy efficient house and allow options for renewable fuels. The second property includes four buildings which are supplied with fuel oil. A change to use natural gas is planned and wherever possible CHP technology for highly efficient use of energy.
