A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

The ubiquity of computing devices has led to an increased need to ensure not only that the applications deployed on them are correct with respect to their specifications, but also that the devices are used in an appropriate manner, especially in situations where the device is provided by a party other than the actual user. Much work which has been done on runtime verification for mobile devices...

Using of colloids and polymeric microparticles are gradually increasing. It is observed that the positive effects of particles stems in both traditional applications such as column pickings, coatings and paints to more recent technologies in diagnostics, drug delivery and optical devices are well documented. This review focuses on importance of colloids and covers their applications on three le...

This paper describes applications of a gesture-based user interface device and its integration into application software. It describes the glove input device used, the gesture recognition software and the integration of the device into application software with the help of a context framework. The system has been used in a number of demonstration applications ranging from desktop applications t...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

Screen readers can drive braille devices for allowing visually impaired users to access computer environments, by providing them the same information as sighted users. But in some cases, this view is not easy to use on a braille device. In such cases, it would be much more useful to let applications provide their own braille feedback, specially adapted to visually impaired users. Such applicati...
