A ventilation system comprising a ventilator or fan to inhale fresh air from environment surrounding enters the cabin of a car where at the same time exhale the hot air to the outside. This invention system is using solar power integrate with the ventilation system in order to stabilize the thermal condition inside the car during sunny day. The solar power is chosen as it is reasonable due to its limitless and environmental friendly source just like mentioned in the previous objective of the project. In addition, a rechargeable battery is used to power the ventilator in the absence of the alternative energy during cloudy day or has obstacle like being shaded by buildings, trees and others. It is just like an extra supply during emergency case. This may prevent the lack of power energy supply for the system. A heat sensor is used as to detect targeted (high temperature) and desired temperature (drop temperature) inside the car. It is operatively connected to a logic circuit to measure environmental factor, wherein the controller (PIC Microcontroller) utilizes the measured environmental condition to allow the power supply to activate or deactivate the ventilator.

Alternative Energy Sources

Purpose The challenges and factors of household adoption and the use of alternative energy sources have been a point of discussion among researchers. The purpose of this study is to apply a variant of the unified theory of adoption and use of technology (i.e. UTAUT 2) to explore the effect of various constructs that influence technology adoption on the consumers’ intention to adopt (and use) solar power generators (SPG) at the household level and the subsequent switching behavior. Design/methodology/approach Based on survey data collected from six cities in India (n = 1,246), factor analysis and structural equation modeling are applied for data analysis and testing the study hypotheses. Findings The results of the structural equation model found UTAUT constructs performance expectancy, effort expectancy, social influence and hedonic to positively affect behavioral intentions to adopt SPG. However, facilitating conditions and perceived value was not found to affect behavioral intentions to adopt SPG. Behavioral intentions to adopt SPG was found to positively influence the switching behavior. Research limitations/implications The present study augments the domain of alternative energy usage behavior by applying the UTAUT 2 in the adoption of alternative energy sources (namely, solar) and subsequent switching behavior from traditional sources at the household level. Practical implications The findings from the present study will guide the marketers and policymakers on the consumer attitudinal and behavioral aspects of solar energy usage at the household level and subsequent switching behavior. Originality/value The present study is novel as it moves beyond household-level behavioral intention to use solar energy and includes the switching behavior to shift to solar power from traditional energy sources.

Significant Attention

Considering the rate of depletion of the available oil-based fuels, Renewable Energy Technologies are receiving significant attention in these years. It is, therefore, necessary to find alternatives to energy sources. This project focusses on one such alternative. A study is done on a vehicle suspension system and braking system. Suspension in vehicles produces linear vibrations due to the roughness on the roads. These vibrations are absorbed the shock absorbers and dissipated in the form of heat. In the case of a conventional braking system,a huge amount of heat is lost due to friction. This study proposes a design of a system where the heat lost in the suspension system is extracted, converted into a usable form of electrical energy and stored in batteries. This stored energy is further used in the operation of electromagnet powered brakes. Using the Regenerative Suspension System reduces the waste of energy in the shock absorbers and gives an alternative energy source and use of the Electromagnetic Braking System ensures frictionless braking. Thus, the overall consumption of energy is reduced by a notable amount.

AbstractThe world is still heavily using nonconventional energy sources, which are worryingly based on carbon. The step is now alternative energy sources hoping that they will be more environmentally friendly. One of the important energy conversion forms by using these sources is photovoltaic solar systems. These type of power plants is on the increase in everyday on the world. Before investment a solar power plant in a specified region, a techno-economic analyse is performed for that power plant by using several meteorological data like solar irradiance and ambient temperature. However, this analyses generally lacks evaluation on effects of climatic and geographical conditions. In this work, 5 years of data of 27 grid-connected photovoltaic power plants are investigated, which are installed on seven different climate types in Turkey. Firstly, the power plants are categorized considering the tilt angles and Köppen–Gieger climate classification. The performance evaluations of the plants are mainly conducted using monthly average efficiencies and specific yields. The monthly average efficiencies, which were classified using the tilts and climate types were from 12 to 17%, from 12 to 16% and from 13 to 15% for tilts 30°/10°, 25° and 20°, respectively. The variation in the specific yields decrease with elevation as y(x) =  − 0.068x + 1707.29 (kWh/kWp). As the performances of photovoltaic systems for some locations within the Csb climatic regions may relatively lower than some other regions with same climate type. Thus, techno-economic performance for PVPP located in this climate classification should be carefully treated.

Cloud Monitoring

This study endeavors to develop a cloud monitoring system for solar plants. This system incorporates numerous subsystems, such as a geographic information system, an instantaneous power-consumption information system, a reporting system, and a failure diagnosis system. Visual C# was integrated with ASP.NET and SQL technologies for the proposed monitoring system. A user interface for database management system was developed to enable users to access solar power information and management systems. In addition, by using peer-to-peer (P2P) streaming technology and audio/video encoding/decoding technology, real-time video data can be transmitted to the client end, providing instantaneous and direct information. Regarding smart failure diagnosis, the proposed system employs the support vector machine (SVM) theory to train failure mathematical models. The solar power data are provided to the SVM for analysis in order to determine the failure types and subsequently eliminate failures at an early stage. The cloud energy-management platform developed in this study not only enhances the management and maintenance efficiency of solar power plants but also increases the market competitiveness of solar power generation and renewable energy.

Ventilator Synchrony

The synchrony of patient-ventilator interaction affects the process of mechanical ventilation which is clinically applied for respiratory support. The occurrence of patient-ventilator asynchrony (PVA) not only increases the risk of ventilator complications but also affects the comfort of patients. To solve the problem of uncertain patient-ventilator interaction in the mechanical ventilation system, a novel method to evaluate patient-ventilator synchrony is proposed in this article. Firstly, a pneumatic model is established to simulate the mechanical ventilation system, which is verified to be accurate by the experiments. Then, the PVA phenomena are classified and detected based on the analysis of the ventilator waveforms. On this basis, a novel synchrony index SIhao is established to evaluate the patient-ventilator synchrony. It not only solves the defects of previous evaluation indexes but also can be used as the response parameter in the future research of ventilator control algorithms. The accurate evaluation of patient-ventilator synchrony can be applied to the adjustment of clinical strategies and the pathological analyses of patients. This research can also reduce the burden on clinicians and help to realize the adaptive control of the mechanical ventilation and weaning process in the future.
