A lot of effort in Qualitative Reasoning had been spent in the RCC-8 calculus. This paper proposes a calculus named OCC (Occlusion Calculus) closely related to Galton’s LOS-14 calculus, that is more expressive in a vision context. The OCC relations qualitatively describe configurations from two convex objects in the projective view from a 3D scene. To set OCC on a mathematical ground an axiomat...

energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. in this paper, byusing the energy consumption data for the residential sector of shiraz in iran, the effect of built area (ba) andoccupant number (occ) on annual energy consumption (ec) w...

Kraft pulping is the dominant process currently used to produce chemical pulps, and has been applied for more than 130 years. A large number of studies have been conducted to gain a better understanding of the delignification kinetics as well as the reactions of the wood components being dissolved during the cooking process. Nevertheless, these remain far from being well understood in detail du...

As technological advances are made in software and hardware, the feasibility of accessing information "any time, anywhere" is becoming a reality. In a mobile computing environment, a potentially large number of mobile and fixed users may simultaneously access shared data; . In this paper, we have addressed the problem and devised an effective OCC protocol with deferred adjustment of serializati...

This study attempts to investigate sociotechnical gaps in online collaborative consumption (OCC) to improve user experience and provide better design requirements. A new approach is proposed to evaluate usability and sociability of the OCC communities. The formation of social capital within OCC will also be studied to gain insights into design requirements. Due to its features as a community wh...

In mammals, the oocyte and its surrounding cumulus cells constitute on oocyte cumulus complex (OCC). During ovulation, OCCs are extruded into the peritoneal or bursal cavity, depending on the species, and are then rapidly picked up by the fimbria on the outer surface of the oviductal infundibulum and transported to the ampulla, where fertilization occurs. We developed a method to measure OCC pi...
