Consumer preferences can serve as an effective basis for determining key product attributes necessary for market success, allowing firms to optimally allocate time and resources toward the development of these critical attributes. However, identification of consumer preferences can be challenging, particularly for technology-push products that are still early on in the technology diffusion S-cu...

The use of fossil fuels to generate electricity has already been identified as a major contributor to global warming and climate change. Many countries have already made plans to reduce their fossil fuel consumption and increased the contribution of renewable energies in total energy supply. One of the commonly used renewable energy sources is the sun and the use of photovoltaic cells to conver...

In this paper utilization of a boost converter for control of photovoltaic power using Maximum Power Point Tracking (MPPT) control mechanism is presented. First the photovoltaic module is analyzed using SIMULINK software. For the main aim of this work the buck converter is to be used along with a Maximum Power Point Tracking control mechanism. The MPPT is responsible for extracting the maximum ...

This paper presents a control structure for transformerless photovoltaic inverters connected in parallel to manage photovoltaic fields in the MW range. Large photovoltaic farms are usually divided into several photovoltaic fields, each one of them managed by a centralized high power inverter. The current tendency to build up centralized inverters in the MW range is the use of several transforme...

Received Nov 12, 2016 Revised Apr 12, 2017 Accepted Mar 20, 2017 Robotic telepresence is an Information and Communication Technology (ICT) solution that has a huge potential to address the problem of access to quality healthcare delivery in rural areas. However, the capital and operating costs of available systems are considered to be unffordable for rural dwellers in emerging economies. In add...

We study a model-based approach to detect sustainable faults of photovoltaic systems. We describe models and algorithms which allow us to analyze a large amount of photovoltaic systems. Our approach is based on median regression. We assume that we know the irradiance and produced energy of a photovoltaic system. The particular challenge of the data analysis problem we study here is the possible...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...
