in islamic republic of iran, the heating and cooling of buildings account for approximately 40% of total energy use. from the entire energy loss taking place in a building, one third of that energy loss occurs through the windows. many of today’s existing buildings are not energy efficient, and consume more energy than is needed in order to make the working and living environments comfortable. ...

The acquisition method for planar 67Ga imaging has hardly changed for 30 years. In this study, in order to improve image quality and diagnostic accuracy, we take steps to optimize the acquisition method, and to choose a scatter correction. First, we acquired individual images from the 93 keV, 185 keV, and 300 keV photopeak; then the images were added together and compared to the individual imag...

In commercial buildings in Lahore, artificial cooling systems are needed to attain the required comfort level due to high heat gain inside. Energy efficient window design is the only solution which can limit this cooling demand. This simulated study is carried out in order to obtain a desirable window size (WWR). The study is carried out by the interpretation of graphical data which is generate...

Automated behavioural classification and identification through sensors has the potential to improve health and welfare of the animals. Position of a sensor, sampling frequency and window size of segmented signal data has a major impact on classification accuracy in activity recognition and energy needs for the sensor, yet, there are no studies in precision livestock farming that have evaluated...

The need for energy conservation has become increasingly important over the last several decades. Several innovations have driven the growth of energy efficient glazing use in residential, commercial and automotive applications. A number of government-private joint efforts are focused on achieving even greater use of energy efficient windows [1]. Even with the high penetration of energy efficie...

For real-time embedded systems, schedulability, energy efficiency, Quality of Service (QoS), and reliability are four highly co-related important design concerns. In this paper, we explore combining these four dimensions of design issues to achieve better schedulability and energy efficiency for real-time systems while satisfying the QoS and reliability requirements. The QoS requirements are de...

Building-integrated photovoltaics (BIPV) are one of the most important sustainability technologies for building energy, and the semi-transparent solar cell is one of the most promising photovoltaic systems for building integration because it can generate electricity and is transparent with a range of beneficial optical properties. On the other hand, the utilization of semi-transparent solar cel...

The aim of the article is to describe the results of an experimental campaign based on the assessment of a heat recovery unit coupled with a dynamic window. Two fully monitored and calibrated outdoor test cells are used, in order to evaluate the energy performance and the related thermal comfort. The former presents a traditional window with double-glazing, aluminum frame and indoor blind and a...
