1	Solar PV System for Electric Traction Application with Battery Backup Swapnil A. Meshram, Shubham A. Kapade, Akshay D. Choudhari, Ritesh S. Kakade, Ankush V. Mhala, Kirti B. Nagane Abstract - The growing interest in the use of energy storage systems to improve the performance of trains has prompted the development of control techniques and optimal storage devices, displacement, and sizing to obtain the maximum profit and reduce the total installation cost. Recently, the rapid diffusion of renewable energy generation from photovoltaic panels has also created a large interest in coupling renewable energy and storage units. A grid connected PV system with batteries as the energy storage element for application to electric train has been proposed in this paper. Battery packs and PV arrays are cascaded together to the utility through a bidirectional dc converter and boost converter. The PV module terminal voltage is regulated by a switched dc-dc step up boost converter, which uses the Incremental Conductance algorithm to track the MPPT. A bidirectional DC/DC converter efficiently regulates flow of power between battery and grid. Bidirectional Inverter provides supporting grid functions which enhances grid stability.	Download
2	Design of Telemedicine System Based on Mobile Terminal Grace Gregory Mihuba, Michael Joseph Shundi, Obadia Kyetuza Bishoge, Anthony Msafiri Nyangarika Abstract - Nowadays, there are a lot of handled devices such as smartphone and tablet PC which provide an opportunity to add more applications to the mobile devices which in turn can save the time of the patient to report to the health practitioners. As a new medical method, the remote medical monitoring system is gaining more attention in providing a rapid diagnosis to patients. For instance, this system can help to save the life of the patients who are in remote and rural areas where there is poor transportation for the patients to go hospitals at a related time. This study suggests a kind of remote medical monitoring system which is based on Mobile Terminal and General Packet Radio Service which allows operation of wireless telemedicine systems deliverance medical personnel and patient from a static site. The remote medical monitoring system is composed of three parts specifically mobile remote medical monitoring unit, monitoring center, and the management system. In this exertion, a telemedicine system protocol is aimed and tested. The results of the study display that this system works speedily with low cost and approachable to any user compared to other systems such as telemedical cardiac system.	Download
3	Performance Evaluation and Experimental Verification of a Novel Solar Water Desalination System H. H. El-Ghetany, H. M. Elgohary, Y. M. Mohammed Abstract - The aim of this work is to develop water desalination unit to produce desalinated water for remote and isolated communities that do not have the infrastructure of potable water networks. The desalination unit using the technology of single effect water distillation that will be thermally driven by solar energy. The studied system is experimentally verified under various weather conditions and studying the various factors that affect the performance of the system. The system condenser is designed to provide double effect of water condensation by using double heat exchanging surface. While the cooling effect is provided by the inlet cold saline water. The installed heat pipe evacuated tube solar collector obtained higher thermal performance and provided higher temperature compared with the flat plate collectors. It is found that the price index of the studied prototype is found to be 2.5 cent USD/ liter of distilled water and 75 cent USD / m3 of drinking water which is positively competitive if it is applied in rural and isolated communities where national electrical grid is not available. From economic point of view, it is found that the payback period is less than one year if the daily production is distilled water, and it is up to seven years if the daily production is drinking water.

4	Experimental Investigation of a Solar Baking System Using Parabolic Trough Solar Collector H. H. El-Ghetany, S. A. Hassan, M. Z. Metias Abstract - The aim of this work is to develop an innovative solar baking system using parabolic trough solar collector. An experimental investigation under various weather conditions is conducted. The experimental pilot unit was installed in Solar Energy Department, National Research Centre, Giza, Egypt. Several test runs are performed to measure all assigned parameters that affect the system performance are conducted. The system is designed to provide thermal energy in the volume enclosure of the baking area that located in the line focus parabolic trough solar collector. The results showed good performance of the solar baker to bake breads and cakes. The tested system can positively contribute in baking purposes in rural and isolated communities where the required ordinary fossil fuel is not available. It is found that to reach the desired moisture content for baking process (35%-40%), it is needed amount of solar radiation dose ranged from 3.7 – 4.0 kWh/m2. it is noted that in autumn and winter seasons the solar radiation dose and the ambient temperature are relatively low if they are comparing with the corresponding values in spring and summer seasons. The lower solar radiation decreasing the solar energy input to the system while lower ambient temperature increasing the overall heat losses and consequently increasing the baking time to reach the desired moisture content.
