Abstract: This paper provides a literature survey of maximum power point tracking applied to the photovoltaic power system. To maximize the PV array output power MPPT algorithm is used in PV systems irrespective of temperature and irradiation of the weather and electrical characteristics of the load. The load resistance should match the source input resistance to increase the power flow from the photovoltaic systems. This paper presents a comprehensive review of maximum power point tracking techniques with various advantages and drawbacks of each technique are identified for different weather conditions. This manuscript would serve as a convenient reference for future work in maximum power tracking control.

Keywords: PV module, maximum power point tracking (MPPT), photovoltaic (PV) power system, DC-DC converter.

Abstract: Traffic light control systems are widely used to monitor and control the flow of automobiles through the junction of many roads. They aim to realize smooth motion of cars in the transportation routes. This paper is designed to develop a traffic signal based on traffic density and also innovative control to clear the traffic for ambulance. During normal situation, the signal timing changes automatically by sensing the density of vehicles.  Conventional traffic light system is based on the fixed time concept allotted to each slots. The proposed system uses and PIC16F877A micro controller (Harvard architecture family) interface with sensors that change the junction timing automatically to avoid unnecessary waiting of drivers. IR sensors are used in this paper to detect the density of the traffic. The Bluetooth operated by Android device override the set timing and give green signal in the desired directions whereas blocking other roads by red signal. Thereby providing traffic clearance for emergency vehicles.

Keywords: Traffic light control systems, automobiles, transportation routes, traffic signal, emergency vehicles.

Abstract: 5G Technology stands for 5th Generation Mobile technology or mobile Networks or Wireless Systems. The 5G technology which is expected to be launched by 2020 it is an upgraded version of the existing and establishing network 4G known as LTE (Long Term Evolution) network, this technology started an era of highly-efficient information society.  5G is a name used in some research papers and projects to denote the next major phase of mobile telecommunications standards beyond the upcoming 4G standards. Currently, 5G is not a term officially used for any particular specification or in any official document yet made public by telecommunication companies or standardization bodies such as 3GPP, Wi-MAX Forum or ITU-R. Mobile communication prime objectives can be improved, including increased capacity, higher data rate, low latency, and better QOS. This paper studies 5G Technology, architecture, waveforms, and makes a comparison between these waveforms and OFDM.
