    Remote accessible laboratory for error controlled coding techniques with the labview software
    (ELSEVIER SCIENCE BV, 2010) AKAR, AYNUR; Erder, Berkay; Akar, Aynur; Uzunboylu, H
    Whilst the laboratory works at faculties providing education on the field of electronics and communication support the technical knowledge of students, they also develop their implementation abilities. The fact that there is less equipment requiring advanced technologies in laboratories, enforces the students to group works and thus limits working time and their contribution to the experiments. Contemporary computer technology provides the possibility for establishing alternative laboratories, environments in which the students can perform implementations without the restrictions of location and time. In this work, real time remote accessible experiment sets are prepared regarding coding techniques with error control. It is provided that the students can connect to the web based laboratory system via any computer on the LAN and make experiments. In this laboratory, the student will perform real time implementations without the restriction of location and time and strengthen their theoretical knowledge. (C) 2010 Elsevier Ltd.

    Analysis and Evaluation of The Electromagnetic Field Pollution in Marmara University Başıbüyük Campus Using Gas Discharge Visualization TehniqueAccording to Different Weather Conditions

    The continuous development of technology and, accordingly, people's interest in technological devices is increasing. Electricpowered devices generate electricity and magnetic fields. The intensity of electric and magnetic fields is restricted by international organizations and limit values by Turkey's Information Technologies and Communication Authority (BTK). The values of the electromagnetic field generated by the base stations are monitored by the BTK. The limit values determined by the BTK are more stringent than those set by international organizations. The intensity of the electromagnetic field varies according to the distance and power to the system. In this study, electromagnetic field pollution in Marmara University Başıbüyük Campus was analyzed periodically and according to different weather conditions. Measurements were performed at 19 different points and the results were mapped. SRM 3006 model selective radiation meter was used in the measurement. Measurement results were compared with international limit values and evaluated. The limit value determined by international organizations for the environment is 61 V/m and the limit value determined by BTK is 42 V/m. 12-day average electric field is 1.53 V/m for periodical measurements. The average electric field in sunny weather is 1.9 V/m, 1.28V/m in rainy weather and 1.39V/m in cloudy weather. Gas Discharge Visualization technique was used to observe the possible changes in the energy and stress situation of the different electromagnetic field pointswithin the campus. Energy and stress measurement with this technique was performed with Bio-well device. According to the measurement results, no change in stress and energy status was observed.
