The Yahoo! music rating data set in KDD Cup 2011 raises several interesting challenges: (1) The data covers a lengthy time period of more than eight years. (2) Not only are training ratings associated date and time information, so are the test ratings. (3) The items form a hierarchy consisting of four types of items: genres, artists, albums and tracks. To capture the rich temporal dynamics with...

This research studies the effect of “disconfirmation”—the discrepancy between the expected and experienced quality of the same product—on the behavior of consumers leaving product reviews in an online setting. Specifically, we posit that an individual’s pre-purchase expectation is driven by the product ratings she observes and the credibility of the review system she perceives at the time of pu...

BACKGROUND Postherpetic neuralgia (PHN) is considered by some investigators to be predominantly a deafferentation-type central pain syndrome; others suggest that activity of remaining peripheral nociceptors plays a critical role. The authors investigated the sensory dysfunction in subjects with PHN of varying duration and at different sites to gain further insight into the mechanisms responsibl...

Temperature profile optimization is one of the most relevant and challenging problems in modern multi-core architectures. Several Dynamic Thermal Management approaches have been proposed in literature, and run-time policies have been designed to direct the allocation of tasks according to temperature constraints. Thermal coupling is recognized to have a role of paramount importance in determini...

The enhancement of heating or cooling in an industrial process may create a saving in energy, reduce process time, raise thermal rating and lengthen the working life of equipment. Some processes are even affected qualitatively by the action of enhanced heat transfer. The development of high performance thermal systems for heat transfer enhancement has become popular nowadays. A number of work h...

This paper proposes the fast and accurate electro-thermal model of existing Simrod three-phase inverter for an electric vehicle (EV) application. The research focuses on analytical dynamic models inverters that can be applied multi-applications. optimal design approach passive filters is presented DC AC sides inverter. has been established, including a mathematical representation induction moto...

In this paper, the nonlinear dynamic buckling of double-walled boron-nitride nanotube (DWBNNT) conveying viscous fluid is investigated based on Eringen's theory. BNNT is modeled as an Euler-Bernoulli beam and is subjected to combine mechanical, electrical and thermal loading. The effect of viscosity on fluid-BNNT interaction is considered based on Navier-Stokes relation. The van der Waals (vdW)...

To quantify the complex relationships between (1) the temperature, and temperature differences, on the surface of the breast as recorded by infrared thermal imaging and (2) the underlying physiological and pathological factors, we have developed a dynamic finite element method for comprehensive modeling of both the thermal and elastic properties of normal and tumorous breast tissues. In the ste...
