The Ostwestfalen-Lippe University of Applied science is a well-reputed state university in Germany, which carries out research and higher education at four locations. OWL belongs to the 10 best research oriented Universities of Applied science in Germany and enrolled approximately 6.700 students in 9 faculties, which offers Bachelor and Master study programmes with a strong focus to Engineering and Technology disciplines. Ph.D.-programmes are carried out in cooperation with different partner universities .The headquarter is in Lemgo, located between Hannover and Dortmund, in the north-east of the state North Rhine-Westphalia. The university is named just as the region Ostwestfalen-Lippe, which is one of the most important technology clusters of mechanical engineering and industrial electronics in Germany. Because of its research strength the university became a full member of the European University Association in October 2010. In the CHE-Ranking 2013/2014 Electrical Engineering was listed as one of Germans best study programmes. Wikipedia.

Nowadays, computer systems are presented in almost all types of human activity and they support any kind of industry as well. Most of these systems are distributed where the communication between nodes is based on computer networks of any kind. Connectivity between system components is the key issue when designing distributed systems, especially systems of industrial informatics. The industrial area requires a wide range of computer communication means, particularly time-constrained and safety-enhancing ones. From fieldbus and industrial Ethernet technologies through wireless and internet-working solutions to standardization issues, there are many aspects of computer networks uses and many interesting research domains. Lots of them are quite sophisticated or even unique. The main goal of this paper is to present the survey of the latest trends in the communication domain of industrial distributed systems and to emphasize important questions as dependability, and standardization. Finally, the general assessment and estimation of the future development is provided. The presentation is based on the abstract description of dataflow within a system. © 2005-2012 IEEE. Source

A big increase in the number of solar thermal cooling installations and research efforts could be seen over the last years worldwide. Especially the producers of solar thermal collectors and systems have been looking for thermal chillers in the small capacity range to provide air conditioning for one or two family houses. Furthermore, many developments aim to increase the efficiency of the system and to decrease the specific costs of the produced refrigeration capacity. The growth in the use of solar thermal cooling systems amounted about 860% from 52 units in 2004 to 450 units in 2009 . This tendency is expected to be continuously in the next years. The practical examinations on solar thermally driven absorption machines with refrigeration capacity of 15, 10 and 5 kW have shown that this technology has a good chance to be standardized and to replace partly the conventional one. These systems can save more primary energy at high fraction of solar thermally driving by suitable control and regulation of the system. The investing costs still higher as the conventional one, however, the operating costs are less than the conventional one. The Coefficient of Performance (COP) depends on the kind of the system, work temperatures and conditions as well as the refrigeration capacity of the systems. It lies between 0.4 and 1.2. In the framework of the research on this field, we built, tested and measured two prototypes. After measuring the first prototype, the chillers were redesigned to reduce internal heat losses and make the heat and mass transfer over the surfaces of heat exchangers more effective. Thus, many investigations have been done on some types of heat exchangers for optimization of heat and mass transfer in the system. In this contribution we will show some investigation results on solar thermally driven system in small capacity range. Moreover, we will illustrate an experimental setup for investigation of heat transfer by shell tube heat exchanger consisting of two kinds of tubes. The first one has a smooth outer surface and the other one has a ribbed outer surface. The aim of these investigations is to optimize the whole system. © 2012 Elsevier Ltd. All rights reserved.

The AnyPLACE (Adaptable Platform for Active Services Exchange) project intends to develop a modular smart metering platform. The targeted system aims to provide a bidirectional service exchange gateway that enhances the interaction between end users, market representatives, electricity network operators and ICT providers. The proposed solution will allow performing energy remote metering (electricity, gas, heating and cooling), exploiting electricity networks in a more efficient manner and turning end users in active energy markets players through their engagement in demand response programs. Moreover, the utilization of the AnyPLACE platform to actively manage and control electricity networks will also allow mitigating operational problems related with the variability of renewable based generation. To enable the development of an effective modular and flexible platform, an analysis to the different regulatory frameworks, energy/telecommunications standards, potential scenarios of deployment, technical requirements of the solution and technologies currently available will be performed. A modular and plug and play SW and HW platform will be developed in parallel with current and expected regulatory initiatives and standards. A cost-benefit analysis on different possible configurations will be developed, to ensure that appropriate configurations, or even retrofitted solutions, are designed for each context and their cost do not exceed 100. A set of prototypes will be built with different combinations of modules to deal with different scenarios of application, which will be tested in a smart grid laboratory environment and in a field trial, providing a real-world assessment of their performance. Near-market prototype versions will be produced, accomplishing the project knowledge and technology transfer to industrial consortium partners as well as general industry and service providers. The AnyPLACE project will also address public acceptance of the designed solutions.
