in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...

gyroscopes are used as rotation rate sensors. conventional gyroscopes are heavy and bulky, which creates important problems regarding their usage in different applications. micro-gyroscopes have solved these problems due to their small size. the beam micro-gyroscope is one of the popular types of inertial sensors. their small dimensions and low energy consumption are key reasons for their popul...

nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. in this paper, ultrasonic assisted turning (uat) isperformed to create the micro textures on the flat faces. micro surface texturing ismade on the al7075-t6 by the uat in the face turning process. then, the influences of cutting speed feed, vibration direction and vibration ampl...

Trajectory clustering has played a crucial role in data analysis since it reveals underlying trends of moving objects. Due to their sequential nature, trajectory data are often received incrementally, e.g., continuous new points reported by GPS system. However, since existing trajectory clustering algorithms are developed for static datasets, they are not suitable for incremental clustering wit...

In this paper, we propose a model called MITS — Mixed Initiative Intelligent Tutoring System for Sudoku. Extrapolating from theory for tutoring in scholastic subjects, and tutoring in the game of chess, we develop a model for tutoring the game of Sudoku using a mixed-initiative paradigm. Moreover, our aim is to design a system which not only proposes moves to make but also gives advice on why a...

A low complexity approach to coding-enhanced multi-user detection is developed to mitigate the problems associated with nearfar effect and to permit a more efficient assignment of channel resources relative to current multiple access (MA) communications systems. Through prudent integration of error correction decoding, multi-user and inter-symbol integeretace equalization and stripping, a low c...

2 0 0 7 • Vo l I I I s sue IV echnological innovation often stimulates economic growth by creating new products, improving efficiency, and opening doors to new markets. Yet many rural communities believe these advantages are off limits to them—because their towns are either too small or too remote for their entrepreneurs to create technological innovations. In reality, though, the advantages of...

Background and Objectives: Furfural (F) and hydroxymethyl furfural (HMF) are cyclic aldehydes, which are formed during the heat processing of foods. These chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. The aim of the present study was extraction and determination of F and HMF in baby-foods using dispersive liquid-liquid micro...
