Information Quality On The World Wide Web: A User Perspective, Jaikrit Kandari
Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research
Information Quality has emerged as an important measure for the success of Information Systems. At the same time the World Wide Web has established itself as the key infrastructure for information administration, exchange, and publication. Users are getting information from the web at the click of a button however they must filter sub-standard information before they can use quality content. Researchers have aimed to address this problem by suggesting various information quality frameworks. Research till date has seen twenty important Information Quality (IQ) frameworks emerge. These models though varied in their approach and application share a number of characteristics regarding …

Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau
Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau
Durham School of Architectural Engineering and Construction: Faculty Publications
Minimization of the sound pressure field within the shadow zone of a noise barrier is achieved by reducing the pressure gradient along a line, at the top of a barrier, via active noise control. The noise control effectiveness of a barrier is increased by this strategy, especially for specific system configurations. The proposed method was evaluated by numerical simulation. Results indicate that system orientation has little effect on minimizing the pressure gradient at the top of the barrier when the error sensors are invisible to the primary noise disturbance. Highly effective control within the shadow zone and close to the …

Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau
Durham School of Architectural Engineering and Construction: Faculty Publications
Predicting the insertion loss of an opening backed with an enclosed space is important for building noise control. Recent research in sound transmission through apertures of finite depth in infinite rigid baffles has included the effects of propagating and evanescent modes within the aperture in order to extend models to higher frequencies. The present study extends the model to the case of the aperture backed by a cavity as opposed to sound radiating into half-space. The role of coupling between the aperture modes, radiation modes, and cavity modes in the transmission was investigated. The results were compared to those of …
