Application Of Fuzzy Narx To Human Gait Modelling And Identification, Seyed Hesami, Fazel Naghdy, David Stirling, Harold Hill Oct 2011

Application Of Fuzzy Narx To Human Gait Modelling And Identification, Seyed Hesami, Fazel Naghdy, David Stirling, Harold Hill

Professor Fazel Naghdy

A new modelling and classification approach for human gait is proposed. Body movements are obtained using a sensor suit recording inertial signals that are subsequently modelled on a humanoid frame with 23 degrees of freedom (DOF). Measured signals include position, velocity, acceleration, orientation, angular velocity and angular acceleration. The identification and modelling method segments the stream of non–linear movement data on the basis of the features extracted from the sensor signals. A model is then created for the movement of every individual. This model is used as a dynamic finger print for that specific individual. In the future stages of …

Application Of A Fuzzy Controller To Seismically Excited Nonlinear Buildings, Mohammed Al-Dawod, Bijan Samali, Kenny Kwok, Fazel Naghdy Oct 2011

Application Of A Fuzzy Controller To Seismically Excited Nonlinear Buildings, Mohammed Al-Dawod, Bijan Samali, Kenny Kwok, Fazel Naghdy

Professor Fazel Naghdy

Focuses on the benchmark control problems for seismically excited nonlinear buildings defined by Ohtori et al. (2000). This benchmark study focuses on three typical steel structures, 3-, 9- and 20-storey buildings designed for the SAC project for Los Angeles in the California region. The first stage of applying the fuzzy controller to this benchmark study for the 3-storey building is reported. The main advantage of the fuzzy controller is its inherent robustness and ability to handle the non-linear behaviour of the structure. This benchmark study is based on a number of evaluation criteria and control constraints and these limitations are …

Urban Climate And Challenges Of Tropical Cities, B E. Omogbai Jul 2011

Urban Climate And Challenges Of Tropical Cities, B E. Omogbai

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This study examines the nature of urban climate, features and the challenges on the developing tropical cities in the 21st century. It argues that the use of principles of urban climate would help in providing comfortable living conditions and problem immune working environments for the inhabitants of tropical cities. The findings reveal that owing to poor environmental planning, inadequate geotechnical landscape surveys prior to the development of urban infrastructures, and non-adherence to the principles of urban climate, challenges of landscape degradation, excessive flooding of the built infrastructures, heat-island effects, and collapse of buildings have emerged. Suggested measures to avert these …

Web Search From A Bus, Aruna Balasubramanian, Yun Zhou, Bruce Croft, Brian Neil Levine, Arun Venkataramani

Opportunistic connections to the Internet from open wireless access points is now commonly possible in municipal areas. Vehicular networks can opportunistically connect to the internet for several seconds via open access points. In this paper, we adapt the interactive process of web search and retrieval to vehicular networks with intermittent Internet access. Our system, called Thedu has mobile nodes use an Internet proxy to collect search engine results and prefetch result pages. The mobiles nodes download the pre-fetched web pages from the proxy. Our contribution is a novel set of techniques to make aggressive but selective prefetching practical, resulting in …

Effects Of Disability, Gender, And Level Of Supervision On Ratings Of Job Applicants, Bradford S. Bell, Katherine J. Klein Apr 2011

Effects Of Disability, Gender, And Level Of Supervision On Ratings Of Job Applicants, Bradford S. Bell, Katherine J. Klein

Bradford S Bell

Using ratings of hypothetical job applicants with and without a disability obtained from both fulltime workers (n = 88) and undergraduates (n = 98), we examined the effects of disability (paraplegia, epilepsy, clinical depression, or non-disabled), gender, and nature of the job (supervisory or non-supervisory) on five job-relevant dependent measures. Contrary to our hypothesis, applicants with a disability were rated significantly higher in activity and potency than applicants without a disability. Further, also contrary to our predictions, gender and job type did not moderate the relationship between disability and applicant ratings. Post-hoc analyses revealed a significant gender by job type …

Justice Expectations And Applicant Perceptions, Bradford S. Bell, Anne Marie Ryan, Darin Wiechmann Apr 2011

Justice Expectations And Applicant Perceptions, Bradford S. Bell, Anne Marie Ryan, Darin Wiechmann

Bradford S Bell

Expectations, which are beliefs about a future state of affairs, constitute a basic psychological mechanism that underlies virtually all human behavior. Although expectations serve as a central component in many theories of organizational behavior, they have received limited attention in the organizational justice literature. The goal of this paper is to introduce the concept of justice expectations and explore its implications for understanding applicant perceptions. To conceptualize justice expectations, we draw on research on expectations conducted in multiple disciplines. We discuss the three sources of expectations – direct experience, indirect influences, and other beliefs - and use this typology to …
