High Step-up DC-DC Converter by Switched Inductor and Voltage Multiplier Cell for Automotive Applications 
Divya Navamani. J † , Vijayakumar. K*, Jegatheeesan. R* and Lavanya. A* 

Abstract - This paper elaborates two novel proposed topologies (type-I and type-II) of the high step- up DC-DC converter using switched inductor and voltage multiplier cell. The advantages of these proposed topologies are the less voltage stress on semiconductor devices, low device count, high power conversion efficiency, high switch utilization factor and high diode utilization factor. We analyze the Type-I and Type-II topologies operating principle and mathematical analysis in detail in continuous conduction mode. High-intensity discharge lamp for the automotive application can use the derived topologies. The proposed converters give better performance when compared to the existing types. Also, it is found that the proposed type-II converter has relatively higher voltage gain compared to the type-I converter. A 40 W, 12 V input voltage and 72 V output voltage has developed for the type-II converter and the performances are validated.

Design of LED Luminaire for Parking Garage - Hao Cui and Si-Hyun Park- Dept.of Electronic Engineering, Yeungnam University, South Korea.

Design of LED Luminaire for Parking Garage Hao Cui* and Si-Hyun Park† 

Abstract – This study aims to design a zonal lumen for parking garage LED lightings of a slim appearance and 20 W/2,000 lm capacity and to fabricate a lighting luminaire accordingly. The frame is of a one-dimensional bar type with a reverse V-shaped section, with LED chips arranged along both sides. To maximize the 60° to 80° zonal lumen, the geometric structure was designed with the apex of the reverse V-shaped section at 40° and both sides at 70°. As for the LED light source, focusing lenses with narrower full-width half-maximum (FWHM) in luminous intensity were used. A ray-tracing simulation method was utilized for the zonal lumen simulation of the given structure. An actual hardware of luminaire based on the simulation results was fabricated and characterized. The suggested model is meant to develop LED lightings with a proper level of zonal lumen required in parking garages.
Keywords: LED luminaires, Parking garage, Zonal lumen

A 3 kW Bidirectional DC-DC Converter for Electric Vehicles Arsalan Ansari, Puyang Cheng and Hee-Jun Kim Dept. of Electronic Systems Engineering, Hanyang University,South Korea.

Abstract – A bidirectional DC-DC converter (BDC) is an indispensable electrical unit for the electric vehicles (EVs). High efficiency, high power density, isolation, light weight and reliability are all essential requirements for BDC. In this paper, a 3 kW BDC for the battery charger of EVs is proposed. The proposed converter consists of a half-bridge structure on the primary side and an isolation transformer and a synchronous rectifier structure on the secondary side. With this topology, minimum number of switching devices are required for bidirectional power flow between the two dc buses of EVs. The easy implementation of the synchronous rectification gives advantages in terms of efficiency, cost and flexibility. The proposed BDC achieves high efficiency when operating in both modes (step-up and step-down). A 3 kW prototype is implemented to verify theoretical analysis and the performance of the proposed converter.

Abstract
 Biomedical engineering deals with the application of various concepts of engineering in the field of medicine and biology mainly for health care purposes thereby improving patients quality of life. Out of the various techniques, the primary focus is to develop a reliable and optimized technique for electro simulation of heart. The present work deals with an improvement in the design of control system for regulating the heart rate of a pacemaker in an efficient way. An Adaptive PID controller based on the Delta rule and Adaptive Correction Factor is proposed in this paper. The Adaptive PID controller is implemented using an Adaptive Loop incorporating MIT rule with the Delta rule. The PID parameters are modified by an Adaptive Correction Factor. Simulation results were performed on the developed cardiovascular system of humans and results show that the proposed adaptive PID controller produces superior control performance than conventional PID controller.

Gravitational Waves - Prof Bruce Bassett

Publicado em 1 de mar de 2016 The AIMS Public Lecture Series presents: "Gravitational Waves - Einstein's Final Legacy and a Revolution for Astronomy" By Prof. Bruce Bassett, AIMS South Africa, SAAO and UCT Abstract: Gravitational waves - ripples in the fabric of space and time itself caused by colliding black holes - were discovered last week by LIGO, opening up a new window on the Universe. In this talk we will explore what they are and why Einstein predicted them 100 years ago, how they are created and why it has been so hard to find them. We then discuss how gravitational waves will revolutionise astronomy by giving us a new sense, the only one that could potentially see right back to the Big Bang.
