Research in automatic speech and speaker recognition has now spanned five decades. This paper surveys the major themes and advances made in the past fifty years of research so as to provide a technological perspective and an appreciation of the fundamental progress that has been accomplished in this important area of speech communication. Although many techniques have been developed, many chall...

Programs with dynamic allocation are able to create and use an unbounded number of fresh resources, such as references, objects, files, etc. We propose History-Register Automata (HRA), a new automata-theoretic formalism for modelling such programs. HRAs extend the expressiveness of previous approaches and bring us to the limits of decidability for reachability checks. The distinctive feature of...

The main goal of this paper is to define a computational measure for quantifying the visual distinctness of targets in complex natural scenes, using a single-channel vision model. The basic features incorporated in the defined target distinctness measure are: (i) an adaptive contrast sensitivity function; (ii) an estimation of image contrast masking and (iii) an estimation of a set of interest ...

Airbus Industrie is considering building a family of double-deck aircraft. A research project was initiated primarily to investigate the effects of the height of the new upper deck on human performance in case of an emergency, but it was also investigated whether factors such as visibility, slide design, and passenger safety instruction might influence individuals‘ performance. A performance mo...

Image intensity variations can result from several different object surface effects, including shading from 3-dimensional relief of the object, or paint on the surface itself. An essential problem in vision , which people solve naturally, is to attribute the proper physical cause, e.g. surface relief or paint, to an observed image. We addressed this problem with an approach combining psychophys...

Studies reveal that the processing of implicit attitudes could be affected by individual differences in cognitive fluency, as well as by the presence of stereotype threat induced when subjects were primed with negative prejudices about their own social group. Using a previously proposed computational model of human performance on the Implicit Association Test, we examine possible processing mec...

In November, 1996, the Message Understanding Conference-6 (MUC-6) evaluation of named entity identification demonstrated that systems are approaching human performance on English language texts [10]. Informal and anonymous, the MET provided a new opportunity to assess progress on the same task in Spanish, Japanese, and Chinese. Preliminary results indicate that MET systems in all three language...

The study explored instructional benefits of a storyline gaming characteristic (GC) on learning effectiveness, efficiency, and engagement with the use of an online instructional simulation for graduate students in an introductory statistics course. A storyline is a game-design element that connects scenes with the educational content. In order to examine the interactions between the storyline G...

A company could grow up steadily and create different values if it makes use of resource efficiently. In the growing process of the digital content industry, using resources efficiently and investing innovation activities are the essential factors in operation performance, R&D performance, and human performance. We build the research framework based on the resource-based theory in accordance wi...

In the current sport-equipment industry, equipment evaluation and/or optimization are mainly done through pure mechanical procedures. It is known that any change of performance environment would cause one to adapt certain aspects of his or her movements to the changed environment. Variation of sport-equipment is counted as an environment change for human performance. Yet, the equipment-induced ...
