guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

This study presents a robust audio retrieval method and discusses its control strategy. In the method, the retrieval target is divided into short segments, each segment is searched respectively and a retrieval window is used to maintain a list of segments that can be searched simultaneously. The method can quickly detect and locate known sound in real-time audio stream, multimedia archives or t...

One method for detecting fraud is to check for suspicious changes in user behavior over time. This paper describes the automatic design of user profiling methods for the purpose of fraud detection, using a series of data mining and machine learning techniques. It uses a rule-learning program to uncover indicators of fraudulent behavior from a large database customer transactions. Then the indic...

Previous research using the chain of compound letters as letter strings in artificial grammar learning (AGL) suggested that visual saliency known as global precedence influenced the extent of learning. In this study the luminance of letter strings in the learning phase was manipulated to investigate the effect of visual input on AGL regardless of top down attention control. As a result, partici...

this research presents a guidance-assistance system for agricultural swing machines. the new automatic steering system controls the vehicle based upon the position of the traces of the previous operation carried out on the field. for each image the trace of the tilled soil by seed drill is placed either on the center line, or on either side of the line. for traces coinciding with images' c...

Given mounting evidence for working memory impairments in dyslexia, letter reversals during rapid automatic letter naming (phonological loop) or rapid automatic letter writing (orthographic loop) may reflect momentary inefficiency of working memory. Few of the children, with or without dyslexia, in a multi-generational family genetics study, produced reversals, but those with dyslexia produced ...

We investigate two systems for automatic disfluency detection on English and Mandarin conversational speech data. The first system combines various lexical and prosodic features in a Conditional Random Field model for detecting edit disfluencies. The second system combines acoustic and language model scores for detecting filled pauses through constrained speech recognition. We compare the contr...

This study determined whether evidence for late selection is due to attention processing or to processing by an automatic system that is separate from attention (two systems framework; Eriksen, Webb, & Fournier, 1990). The task was a two-choice discrimination of a target that appeared in one of two sequentially cued locations in an eight-letter visual display. Attention was directed to the firs...
