In this paper, we empirically test the relation between price discrimination and product market competition in a two-sided market environment using a new data set of Spanish local TV stations that provides information on subscription and advertising prices per station for 1996, 1999 and 2002. Due to changes in regulation during this period affecting the degree of local market competition, we us...

Abstract: The assembly of complex microsystems consisting of several single components (i.e. hybrid microsystems) is a task which has to be solved to make mass production of microsystems possible. Therefore, it is necessary to introduce flexible, highly precise and fast microassembly methods. In this paper, the control system of a microrobot-based microassembly desktop station that has been dev...

Increasing load of air pollution in urban environment emphasises the need for detailed evaluation of wind characteristics that significantly affect the air quality of urban areas, especially, in large agglomerations. This paper includes analysis of urban wind cli-matology and estimation of wind profiles based on measurements of the new urban 5 climate station located at the E ¨ otvös University...

PURPOSE Objective structured clinical examinations (OSCEs) use standardized patients (SPs) to teach and evaluate medical students' skills. Few studies describe using OSCEs for cultural competence education, now a Liaison Committee on Medical Education accreditation standard for medical schools. We designed an OSCE station emphasizing cross-cultural communication skills (ccOSCE) and interviewed ...

People around the globe recognise that the current development trends are clearly unsustainable and that education can be seen as a critical tool for advancing our society towards sustainability. This paper showcases a case study for ‘Envisioning a sustainable Guwahati Railway Station Complex of the future’ undertaken by students of the Department of Design at the Indian Institute of Technology...

The function of a power station is to deliver power to a large number of consum ers. However, the power demands of different consumers vary in accordance with their activities. The result of this variation in demand is that load on a power station is never constant, rather it varies from time to time. Most of the complexities of modern power plant operation arise from the inherent variability o...

We develop an analytic and a simulation model for a job shop with unreliable work stations and production constraints. In the complex batch manufacturing operation of the factory, smooth production of each work station is required. In the previous work the Tactical Planning Model was proposed for this purpose. In that model, the production of each work station should be proportional to the queu...

We consider a user-centric co-operative cellular network, where base stations close to a mobile co-operate to detect its signal using a (joint) linear minimum-mean-square-error receiver. The base stations, which have multiple antennas, and mobiles are modeled as independent Poisson Point Processes to avoid dependence on specific node locations. Combining stochastic geometry and infinite random ...
