ABSTRACT The use of renewable energy sources is encouraged to meet the rising energy demand. Monitoring of photovoltaic (PV) systems and gathering statistical data are important issues in renewable energy applications. This study presents the implementation of a PV system where the panel output data are gathered and transmitted through the wireless medium using Wi-Fi. This method allows remote monitoring of a PV system. The data about voltage, current, and power production can be collected and reported separately for both DC and AC units. The DC and mono-phase AC measurement values are transmitted via a Wi-Fi access point to the computer where the data are collected. The system has been designed as a basic prototype PV system model with two 100 W solar panels, an AC inverter, a charge regulator, and two accumulators. A current transformer with 40/5A ratio has also been included in the system. Analog to digital converters have been used for both AC and DC measurements. EV100 series single phase intelligent power meter, and AcuDC 210/220 series DC power and energy meters have been used for AC and DC measurements respectively. The advantage of the presented model is the ability to monitor PV systems remotely through the Wi-Fi wireless communication medium. This method allows data monitoring with PV systems in environments where the cabling is complicated or impractical. The data gathered via the wireless access point are monitored with a computer, and can be listed with the software interface. This method provides a practicle and useful model to acquire data and monitor PV systems. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

ABSTRACT For countries and regions enriched with water surfaces such as rivers and lakes, the cheapest source of power is water. Hydro power is called also “pure power” as it has minor pollution effects on the environment and health if compared with other types of power sources. Surge tanks have important role in the functionality of HE plant as they balance the pressure variation in cases of sudden rise or decrease. They are a massive construction that can receive the water in several cases. The cost of these tanks varies according to several factors such as dimensions, construction and maintaining works and shape. This paper aims to compare the cost of several shapes and types of surge tank in the case of Pumped storage HE plant Vrilo by fixing the needed outcomes such as the maximum and minimum level of water needed for producing the expected energy, the location of tank and the materials used for it.

ABSTRACT Earthquake is of the natural disasters that cause great destruction and loss of life in places where they occur. Turkey, a large deal of whose territory stretches on first-degree earthquake zone and on which a large number of earthquakes occurred in the past, is an earthquake country. May 17, 1999 Marmara Earthquake, which was felt in large part of the country in recent past, is the most painful experience. Unpredictable and unavoidable impacts of earthquakes urge all actors of crisis management to think strategically and make effective decisions. Crisis management is composed of a four-step process including pre-earthquake preparedness, first responders, recovery and reorganization. Reducing the loss of life and property depends on the pre-planning of an earthquake and making all necessary preparations. Considering all kinds of possibilities, planning and organization are carried out in this process which is described as proactive crisis management. Burdur, stretching on first-degree earthquake zone and having experienced great destructions in the past, is one of the provinces which must be constantly prepared to earthquakes. Different-scale-earthquakes in 1842, 1876, 1901, 1914, 1925, 1930, 1963, and 1971 are known to have occurred in the triangle of Burdur, Isparta and Dinar. The objective of this study is to examine the different aspects of earthquake preparation of general and local government agencies in Burdur. In this paper, it is aimed to scan the literature regarding the study and to conduct direct talks with senior administrators responsible for managing the earthquake crisis in the city. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

ABSTRACT The aquaculture industry is one of the fastest growing animal husbandry industries in the world with its annual growth rate. However, several disease outbreaks are posing a problem to the development of this sector. These problems constitute the largest single cause of economic losses in aquaculture. Therefore, new methods are needed to overcome disease problems. In the last decades, many fish farmers have attempted to use food additives and antibiotics to cope with fish disease problem. However, the use of antibiotics in fish farming is restricted in many countries due to occurrence of antibiotic residues in aquaculture products that threat human health. Antibiotics also cause immune-saving effect in aquatic pathogenic bacteria. Therefore, several new environment-friendly preventive and prophylactic methods are being developed nowadays to control such diseases and to maintain a healthier microbial environment in aquaculture systems. One of the methods used are probiotic supplementation to the aquatic animal in order to manipulate the gut flora and to control the microbial activity. The probiotics are described as live microorganisms which have beneficial effects on the health and physiology of host organisms. Prebiotics are also defined as non-digestible materials which provide host isolation by inhibiting the activity of harmful pathogenic microorganisms in the environment as well as supporting the development of beneficial probiotic bacteria by dint of mechanisms of various actions in the environment.

ABSTRACT All dielectric self-supporting (ADSS) fiber optic cables have been installed in power transmission lines. As time passed, ADSS cable failures started to occur since ADSS cables, placed under transmission lines, have been subjected to a high electrical field. Dry band arcing is one of the electrical phenomena that causes most of these failures and it is a common problem in industry. In order to investigate the reasons of cable failures, several studies have been carried out and a new testing method was developed for the IEEE 1222 standard. This new method simulates the actual field conditions for ADSS cables, and at the same time, it determines the dry band arcing resistance. Rather than defining the insulation strength of the cable, the IEEE 1222 method decides the quality of the cable insulation material. In this study; two different dry band arcing test method is used to investigate the surface behavior of ADSS cables.

Keywords:Dryband Arcing, ADSS Cable, Aging, Insulation material. ABSTRACT All dielectric self-supporting (ADSS) fiber optic cables have been installed in power transmission lines. As time passed, ADSS cable failures started to occur since ADSS cables, placed under transmission lines, have been subjected to a high electrical field. Dry band arcing is one of the electrical phenomena that causes most of these failures and it is a common problem in industry. In order to investigate the reasons of cable failures, several studies have been carried out and a new testing method was developed for the IEEE 1222 standard. This new method simulates the actual field conditions for ADSS cables, and at the same time, it determines the dry band arcing resistance. Rather than defining the insulation strength of the cable, the IEEE 1222 method decides the quality of the cable insulation material. In this study; two different dry band arcing test method is used to investigate the surface behavior of ADSS cables. At first cables were tested according to IEEE 1222 test standart then at the same laboratory conditions, ADSS cable samples studied for the first time under the sag conditions. The results taken from the experimental work were studied with weibull statistics.

ABSTRACT The use of a solar cell in space requires the knowledge of its behaviour under high-energy partial radiation.This radiation in space produces defects in semiconductor that cause a reduction in solar cell power output. In this paper we present the method for predicting the behaviour of a solar cell for satellite applications. Modeling has been performed for several types of GaAs and GaInP single cells and results are compared with experimental data obtained for electron and proton irradiations. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
