Purpose This study presents the results of empirical measurements thermal performance retrofitted secondary glazed windows, involving installation an additional windowpane, in a residential context Australia. Design/methodology/approach In situ temperature were collected from surfaces windows two buildings Australian Capital Territory. The heat loss savings and subsequently electricity calculat...

Smartphones are rapidly replacing the traditional cellular phones because of its PClike features which allow them to be used as web browsers, editors and media players. These devices run complete operating systems that allow installation of third party applications. As their usage grows, the need for securing the user data stored on these devices and the services that they provide becomes more ...

In this paper we develop a new procedure for entropic image edge detection. The presented method computes the Jensen–Shannon divergence of the normalized grayscale histogram of a set of multi-sized double sliding windows over the entire image. The procedure presents a good performance in images with textures, contrast variations and noise. We illustrate our procedure in the edge detection of me...

In this paper, the sensitivity of a plasmonic nanodipole antenna array for different materials of the metal nanodipole and substrate is calculated by changing the refractive index of the surrounding medium. The performance of our proposed array is studied at two wavelengths of 1310 and 1550 nm, the wavelengths of the second and third telecommunications windows. It is shown that by using the sil...

windows have a major role on absorbing solar energy, reducing heat loses, and adding their values in traditional houses in ardabil. the main aim of this research is to study windows as elements of beautification and production of clean and free energy. we discern that windows can be designed to respond to the regional climates. to explore that, we review four samples of the windows in the famou...
