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...

In the paper, a new physical principle for designing of a new optoelectronic device and its theoretical description are presented. The basic idea of the device consists in providing inside a multilayered semiconductor structure such conditions for photoelectrons that enable sequential avalanche multiplication of electrons and holes inside two depletion slabs created around p-n junctions of a re...

Multimedia computing requires support for heterogeneous data types with differing storage, communication, and delivery requirements. Continuous media data types such as audio and video impose delivery requirements that are not satisfied by conventional physical storage organizations. In this paper we describe a physical organization for multimedia data based on the need to support the delivery ...

This technical report describes (a) a method for efficient on-device positioning that is based on the radio frequency fingerprint model, (b) a method for compressing the fingerprints that are used with this positioning method and, (c) a method for estimating the physical distance between two or more devices. Our positioning method, called Weighted Gaussian Distance, achieves similar positioning...

{Multimedia computing requires support for heterogeneous data types with differing storage, communication, and delivery requirements. Continuous media data types such as audio and video impose delivery requirements that are not satissed by conventional physical storage organizations. In this paper we describe a physical organization for multi-media data based on the need to support the delivery...

Digital Clay is a term that signifies a computercontrolled physical surface, capable of taking any of a wide variety of possible shapes in response to changes in a digital 3D model or changes in the pressure exerted upon it by bare hands. The physical properties of such a device impose design and user-interface constraints not encountered in traditional, tracker-based software for the manipulat...

| This paper presents a novel RF IC varactor implemented in standard CMOS process. This device has shown a remarkable tuning range of 150%, sensitivity of 300%/V, and quality factor of 23 at 1 GHz. A physical model of the varactor is presented and con rmed with measured data. Using the model derived, optimization has shown that a Q as high as 200 can be achieved.

This article describes the use of computer-aided techniques to produce a wax pattern of a missing ear. A 3-dimensional (3-D) computer model of a conventional cast from a patient was obtained using an optical surface capture device (scanner). The 3-D computer model was inverted, using computer-aided design software. A physical thermoplastic (wax) pattern of the inverted 3-D cast was produced usi...

This paper presents an application of a user modelling web service in personalizing interfaces for users with age-related and physical impairment. The user model stores user profile in standardized format independent of application and device. It allows users to carry the profile with them irrespective of device and application. The user modelling web service is used to adapt interfaces of a se...

A method for MEMS macromodel development is presented which is based on a physical device description to obtain mathematical relations for the device operation. Since design and technology parameters are input parameters of the resulting model, this method is well suited for design studies. As a benchmark problem, we refer to the macromodel of a micropump driven by an electrostatically actuated...
