The paper deals with the development of an analog electronic wattmeter which is simple in design and can measure power, from very low values to very high values, with simple modifications, at different frequencies and with good order of accuracy. It can also be used in the measurement of power of distorted signals and can be interfaced with out any loading error. Basically, it measures I cosPhi with...
A circularly polarized conical-beam patch antenna that employs a hybrid feeding mechanism for wideband operation is presented in this paper. It is implemented through using a pair of L-probes and apertures, which are connected by the feeding network, to excite the circular patch in orthogonal directions. The patch is supported by two plastic posts of 0.084 lambda0 height in the air, where lambda0...
A new carrier recovery algorithm for bandwidth efficient modulations at low signal-to-noise ratios (SNR) is proposed using only 5 to 10 percent of overhead symbols. It obtains carrier offsets without using conventional phase differentiation, thus avoiding noise enhancement, which is a limiting factor at low SNR, and also does not utilize periodical preambles, which have undesired emissions and probability...
Now many of the small scale power plants are controlled by the conventional analog instruments with poor performance and reliability. It is an economic way to use the intelligent digital controller to upgrade the automatic control and instrument system of these power plants. In this article the intelligent feature of a new kind of digital controller is described briefly and then its application in...
Linear detection of the downlink signals of a direct-sequence code division multiple-access (DS-CDMA) system has seen significant research in the past years. Notable amongst such efforts is the generalized RAKE (based on ML criterion) and the RAKE receiver based on symbol-level MMSE. Both these approaches aim to suppress interference even while exploiting diversity. We show analytically that these...
Based on analytical method, we show that when IP traffic is loaded directly over differential phase shift keying (DPSK) wavelength-division-multiplexed (WDM) systems with perfect dispersion compensation, the burstiness of IP packets has significant effects on the cross-phase modulation (XPM) induced nonlinear phase noise, and therefore exerts an influence on the packet-error probability performance...
To distribute a parallel process to several computer boxes through a computational Grid, there are three fundamental problems. They may be running on different platforms, for example, WinXP, Linux, etc. The process itself can be written in different programming languages, such as Fortran 90 (an older version was Fortran 77), Ansi C, C++, and Java 2 (very common in Internet application). The last but...
Compressors constitute an integral part of most turbo machinery systems and are widely used in many chemical, industrial, and aerospace applications. The performance map of compressor is influenced by IGV closure angle and relative humidity of air. The calculation model of axial flow compressor is built in the paper, and the influence of IGV and relative humidity on performance map is analyzed in...
The unresolved problem of finding an adaptive LMS structure for ternary filters has substantially limited their useability despite their major advantage of hardware simplicity. In this paper we tackle this challenging problem by introducing an algorithm that seems to be quite promising. Results were surprising as it appeared that the proposed ternary algorithm is comparable in performance to the multi-bit...
We describe progress towards the provision of realistic cutaneous information to accompany kinaesthetic input currently available in devices used to haptically explore virtual objects. A temperature change at the fingertips is made coincident with "touching" a virtual soft drink can. Pressure orthogonal to the skin surface contacting the virtual surface can be incorporated in a similar way.
A ternary ADC using multi-valued logic levels of 0, 1 and 2 is developed. Properties of uni-polar ternary windows are modified to suit asynchronous conversion of bipolar signals. Two algorithms are presented, one giving a straight ternary code uses identical digit cell topologies while the other gives an additional offset ternary code. P-Spice simulation results of 3-digit circuits are presented.
On wireless grids users and resource providers are not only mobile, but also nomadic. Information services on wireless grids have special requirements. Resource information has to be updated when users and resource providers arrive and depart frequently. Meanwhile, information services are also mobile, so the clients and information sources should dynamically detect the existence and departure of...
Contamination-driven insulators failure causing wooden pole fire is a problem that increasingly disturbs H.V distribution systems in Australia as well as other countries of the world.. This paper presents an improved mathematical model for leakage current with various wood parameters and different environmental factors using dimensional analysis technique. The objective of the study is to understand...
This paper mainly presents application of human machine interface (HMI) for real time tracing, monitoring, and operation in steel manufacturing industrial automation system, which are realized by the Programmable Logic Controllers (PLC) to collect process data and transmitted by the integrated computer networking-PROFIBUS DP. In the tracing aspect, one of the newest monitor device-Process Data Acquisition...
We herein present the extended cell splitting algorithm, which first splits bounded or unbounded one-dimensional cells, one at a time, and splits cells of dimensions greater than one. An evaluation of the algorithm is also presented.
Based on cellular mobile net, TDOA positioning algorithm has been demonstrated by many parties in the recent years, however, low degree of accuracy compared with GPS limits its usage in vehicle positioning and navigation services. Here we introduce two assisted technologies, the Digital Road and the Dead Reckoning, to improve the performance that of TDOA. This paper discusses on the methods and feasibility...
