Abstract

Residential security applications by using computer technology has grown rapidly. Motion detectors, contacts on doors and windows, sirens, and a leading provider of security services for housing security management has been widely applied in electronic-based. A simple and practical use of residential security application could improve the performance efficiently and savings the cost. e-KTP card as RFID-based is used for single sign-on access on residential security areas. A reader-tag generates passively electromagnetic waves which inductances the carrier frequency of 13, 56 Mhz which produce output power around 30 dbm is assumed. In order to improved the security performance, e-KTP is integrated with software system using delphi 8.0. Theoritical results shows that a reading tag capability has measures the distance is λ = 0 cm to 2 cm has been achieved. Moreover, e-KTP is sufficient for actively sensed by reader tag. At the λ = 1 cm (0.01 m), Pt = 1 watt, therefore the received power is 0.0011 watt (0.4 dbm). This power has induced by reader tag to generate power in e-KTP. The results shows that the more distances are longer, the greater power is needed to induces e-KTP by reader tag. Keywords: e-KTP, RFID reader, Residential Security Management

Abstract

Freshwater and energy scarce are now becoming most important issues worldwide. Freshwater or potable water is the most important for human life. The rapid growth of population and industrialization contribute on the freshwater scarce. Conventional energy such as fossil fuel faces the similar trend with freshwater scarce since it is not renewable. The price of conventional energy is increased along with the scarcity. Desalination techniques have been developed for decades to be alterative way in providing freshwater. The desalination processes are driven by energy either thermal, mechanical and electricity.Efficiency for desalination system using simulation/Matlab, driven by renewable energy has derived great attention from scholars and engineer worldwide to get over freshwater need and energy issues. One of major concern in this field is to develop low cost desalination system that driven by renewable energy.

Abstract

Information technology is always developing and has very rapid growth. The internet has become a very important online communication tool for many people today. Nowadays people tend to prefer anything that is practical, faster, and flexible. Social networking services have become a simple and universal concept in the internet environment. Purpose of this study are: To analyse happiness of Libyans people based on Twitter data using artificial neural network. This study is an analytical study of secondary data processing obtained without direct field experiments. MTE (Magister program of Electrical Engineering) UNISSULA must have experiment. This study is an analytical study of data based on social media specifically using twitter data. The result of this study is Libyan feel they write down their feelings when happy rather than unhappy. Social media has become an important part of modern life, and Twitter is again a center of focus in recent events. Whatever your opinion of social media these days, there is no denying it is now an integral part of our digital life. Twitter is a good starting point for social media analysis because people openly share their opinions to general public. This is very different from Facebook where social interactions are often private. In this paper, we propose a ANN model for Twitter opinion mining prediction and classification approach. Also, we used the ANN model for Twitter Opinion abstraction and visualization scheme. The main contribution of this work is to propose such a new visualization model for Twitter mood prediction based on ANN  approach
