Abstract:
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California<br>This paper presents the development of two distributed terrestrial radiolocation algorithms that use range estimates derived from DS-CDMA waveforms. The first algorithm, which is RLS-based, is derived as the solution of an approximate least-squares positioning problem. This algorithm has the advantage of reduced computational complexity, compared with the EKF-based algorithm that is presented. It is shown via simulations that both positioning algorithm

Abstract:
An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. The algorithm is based on a physical model of the vehicle and is designed to be able to run in real-time onboard a vehicle and uses the wheel torque signal calculated in the electrical control unit in the engine. Therefore no estimation of the powertrain is needed. This is one contribution that distinguishes this thesis from previous work on the

Abstract:
On a regular basis, project managers concentrate their efforts on critical and near-critical activities. However, the concepts of total float and critical path lose their significance after applying resource-constrained scheduling (RCS) methodologies. RCS techniques solve the resource conflicts but create phantom float in the schedules (i.e., a float that does not exist). RCS techniques overlook the resources relationships between activities that compete for the same but unavailable resources. Therefore, each time an activity uses this apparent float (phantom float), there is a resource violat

Today’s aerospace industry continues to exploit liquid hydrocarbon fossil fuels.

The interplay of liquid atomisation, spray vaporisation and the combustion process are intricately linked. However, the physical process of fuel injection and its atomisation into tiny droplets prior to combustion remains poorly understood. Because atomisation governs the size of the fuel droplets, and therefore their subsequent evaporation rate, adjust

RLVs typically use combinations of different types of engines used in sequence over the duration of the flight.

Methods of new blind channel identification and equalization have lots of breakthrough too. It is noticed that the single-input and multiple output (SIMO) structure is resulted from over-sampling technique in time or space domain. Such a structure lend itself to identification and equalization and is promising to develop a new field and be very usefulness in the wireless communications. In this thesis, we base on the use of the mutual-reference property of SIMO

碩士<br>國立臺灣科技大學<br>電子工程系<br>88<br>Abstract In this thesis, we propose an adaptive algorithm for tuning the forgetting factor. In the time varying environment, conventional RLS algorithm entail a tradeoff between the estimation noise and lag effect. For minimizing excess MSE, we obtain an appropriate forgetting factor that gives the RLS algorithm a good balance between the effect of the estimation noise and lag effect. We decrease the value of forgetting factor when the influence due to time varying channel is stronger than the influence due to noise, whereas we increase the value of

Abstract:
碩士<br>輔仁大學<br>電子工程學系<br>94<br>This thesis proposes two new algorithms: (1) square-root-free (SRF) QR-decomposition-based least-squares lattice (QRD-LSL) interpolation algorithm; and (2) SRF (QRD-LSL)-based recursive least-squares (RLS) algorithm. The SRF QRD-LSL interpolation algorithm requires O(N) computational complexity and the SRF (QRD-LSL)-based RLS algorithm needs O(Nlog2N) operations. Our simulation results show that two algorithms appear to be numerically stable in finite-precision environment with only 5 mantissa bits. To the best of our knowledge, the proposed RLS algorithm may be
