since the energy consumption has become one of the crisis of modern buildings, modeling the iranian past architecture patterns could be helpful. the shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. however, using passive techniques, the iranian traditional bazaars architecture solved the problems regard...

This paper examines and compares households' willingness to accept (WTA)/willingness to pay (WTP) ratio for solar power equipment on their premises through both a novel experimental approach and conventional techniques. The experimental approach was administered by using a Becker-DeGroot-Marschak method and cheap talk, with open-ended questions of WTA/WTP. The results were quite striking. The r...

This thesis documents my personal contribution to the development of a hydraulic-based actuation system for a solar trough collector. The goal of this project was to design the actuation system using hydraulic actuators for a four meter solar collector prototype in Pittsfield, New Hampshire. After considering several hydraulic system architectures and conducting in-depth analysis into two of th...

Aiming at the different sampling rates of multiple sensors for the real-time detection system of heat faults in high-voltage equipment in substation, the step by step prediction fusion algorithm based on synchronous sampling data was used to rapidly calibrate the location of thermal faults. And a new method that using infrared thermal imager together with CCD (Charge Coupled Device) camera and ...

Mathematical modelling and defining useful recommendations for construction and regimes of exploitation for hot water solar installation with thermal stratification is the main purpose of this work. A special experimental solar module for hot water was build and equipped with sufficient measure apparatus. The main concept of investigation is to optimise the stratified regime of thermal accumula...

Telecommunication and broadcasting systems using radio-relay/base stations on board the high altitude platforms are expected to create the largest business market among its possible applications. Telecommunications Advanced Organization (TAO) and Communications Research Laboratory (CRL) is conducting R&D on the telecom and broadcasting system to demonstrate its feasibility. Prototype onboard eq...

Access to electrification in rural areas of East Timor is extremely limited with as few as 5% of rural households connected to electricity. The government of East Timor intends to increase rural access to electricity significantly in the coming decade. The introduction of small PV systems is envisaged for many households in the most remote areas. Several agencies have piloted the introduction o...

Photovoltaic phenomenon was first observed by E. Becquerel (Becquerel) in 1839. He observed the electric current-lit silver electrode, immersed in the electrolyte. In 1894, taking advantage of the observed photoconductivity phenomenon in amorphous selenium the semiconductor solar cell was developed. The very first silicon p-n junction solar cell was made in 1954, energy conversion efficiency of...

One of the task of the LAPAN is making obsevation and forecasting of solar storms disturbance. This disturbances can affect the earth's electromagnetic field that disrupt the electronic and navigational equipment on earth. It would be dangerous to human life if not properly anticipated. LAPAN wanted a computer application that can automatically classify the type of solar storms, which became pa...
