Indonesia has different weather factors than the subtropical climate that influences the performance indicators of photovoltaic systems. One of them is performance ratio that is affected by temperature factors. NREL proposes calculation method of Weather-Corrected Performance Ratio for correcting factors (temperature) in calculation performance ratio of photovoltaic systems. However, the implementation of this method in real operating condition of photovoltaic system especially in the tropics, has not received special attention. In addition, temperature coefficient of power photovoltaic (δ) in Standard Test Condition, is used in the calculation method may be different in real operating condition. This study was conducted to determine the effects of weather-corrected performance ratio method and to know characteristic of temperature coefficient of power photovoltaic (δ) as factors in of weather-corrected performance ratio method, in real operating condition especially in tropics. Through analysis photovoltaic system data from the data logger it is found that the range values of weather-corrected performance ratio are greater than conventional methods, with a maximum increase of 2.43%. Moreover it is found that because average temperature of tropical climate is higher than subtropical climate, it makes the percentage of power decrease to rise in temperature (δ) in tropical climate is higher than subtropical climate.

Supercharged Engine

This article take the Dongan 465Q non-supercharged engine as the research object, the simulation model is built by GT-POWER and the corresponding test bench is set up. The simulation error is less than 3%, which indicates that the parameters of this model is correct, and can be used for further study of the gasoline engine. The supercharger, Garrett GT12, is selected by the matching calculation. The non-supercharged 465Q engine is modified as a turbocharged engine. The test results show that the power and the fuel consumption of the turbocharged engine is improved obviously, whose power is increased by 48% and fuel consumption is reduced by 4%.

Formula one is one of the world's most high-paced sports in which a fraction of seconds can cost a win. From the method of calculating the time spent on a pitstop, when the car should come for the pitstop, fuel consumption, race strategy, aerodynamics, mechanics, engine power is all influenced by operation research. The paper aims at different techniques such as optimization and simulation, further discussing the different types of methods used. It provides brief information about the outcomes, drawbacks, and recommendations given for the efficient use of these techniques in the F1 racing world. It also addresses improvements that can be done by logistics, the necessary factors which need to be considered in the simulation model, and so on. The main objective is to study these techniques and provide an overview and limitations of each method, emphasizing the need for additional research to find solutions.

The One

<p class="0abstract">The development of a tool to analyse data collected in car road tests is presented, allowing a better understanding of the Physics of car motion. Using the measured data of fuel consumption and the main variables related to the vehicle displacement, it is possible to make corrections to the influence of the main disturbing factors and clearly improve the quality of road tests based evaluations. Thus, the fuel consumption rate is continuously recorded during the motion of the vehicle, whereas the power required to ensure displacement can be calculated using a simulation model with the data recorded during a path. Integrating over time the average power values at each interval, the energy necessary to ensure the vehicle displacement is calculated, while integrating the fuel rate over the duration of the path, the fuel consumption is computed. The ratio between the theoretically required energy and the one actually spent provides the conversion efficiency of the vehicle propulsion system. The developed tool is very useful in the framework of the courses about car dynamics included in Mechanical or Automotive Engineering Programmes. The developed tool couples data collected during road tests with a simulation model that computes all the force components acting on the car body during the motion. It has been written in LabView and an attractive graphical interface is used to keep the attention of the students when the data is displayed in real-time or analysed based upon previously recorded files.</p>

The Mathematical Model

In the large fluctuation transition process of hydropower unit, hydraulic turbine operating condition changes drastically, following the change, hydraulic-turbine transfer coefficients also change drastically, thus the mathematical model of hydro-turbine governing system is nonlinear. This paper establishes simulation model of large fluctuation transition process in SIMULINK software, puts forward a method of establishing simulation model of nonlinear hydro-turbine governing system.
