by JEREMY TARVER (Under the Direction of Walter D. Potter) ABSTRACT The semi-autonomous wheelchair uses a multi-layered intelligent agent architecture designed to provide people with severe multiple disabilities navigational assistance in indoor environments. This paper describes the addition of computer vision capabilities to the semiautonomous wheelchair. Specifically an intelligent agent des...

the management of agricultural education faces on-going challenges to deliver current and effective materials in an approach that takes advantage of developments in education technology. in this article the use of blended learning was compared with the traditional approach for the instruction of theoretical materials in agricultural education. this study used a pre-test, post-test experimental ...

in recent years there has been studies concerning the investigation of macro-scale geomorphic proxies of quaternary climatic changes in the study area. without detail analysis of slope geomorphic features, there can be little progress on expanding the knowledge of past slope development in the northwestern iran high mountain environments. consequently, the information pertaining to these quater...

Recently, traditional data mining algorithms are challenged by two problems: streaming data, and changes in the hidden context. These challenges emerged from real-world applications such as network intrusion detection, credit card fraud detection, etc. Online or incremental learning becomes more important than ever for dealing with these problems. This chapter investigates XCS, an evolutionary ...

The Time Of Arrival (TOA) of a received signal is the most important parameter for position estimation. The accuracy of the estimated TOA is limited by multipath errors. Consequently, multipath mitigation techniques are essential for high accuracy positioning using TOA observations. Narrow Correlator and double delta correlator were introduced to reduce multipath errors in pseudoranges. These c...

This paper addresses the problem of noise robustness of automatic speech recognition (ASR) systems in noisy car environments using a Minimum Mean-Square Error Short-Time Spectral Amplitude Estimator (MMSE-STSA). This was accomplished by the integration of an adaptive time varying Noise Shaping Filter (NSF) with the MMSE-STSA algorithm in order to improve the speech enhancement performance by “w...

Di erences in arrival times of acoustic waves at multiple sensors permit the computation of source location. The computation depends upon delay estimation between sensor pairs. In severe acoustic environments, the estimates are degraded by reverberation and interfering noise, and some estimates are poor, constituting outlier. This report describes a computational method for outlier elimination ...
