We offer a parsimonious definition of large population potential games, provide some alternate characterizations, and demonstrate the advantages of the new definition over the existing definition, but also show the equivalence of the two definitions.

This paper reports on an experimental study evaluating a window air conditioner's performance when R152a/R290/R600/R600a refrigerant mixture (by various mass percentages) is used as possible alternative to R-22. Alternative refrigerants are local, cheap, and environmentally friendly. Unmodified R-22 AC was charged with R152a/R290/R600/R600a. During the experiment, parameters such coefficient of...

Energy is in higher demand than ever before since there are an increasing number of applications for it; nevertheless, the existing sources unable to supply it sufficient quantities. Alternate energy should be utilized, and as a consequence, conservation achieved through utilization waste heat from air conditioning systems. The major objective this piece make use generated by residential system...

CFD was applied to evaluate the performance of both existing and improved designs for refrigerant distributors. In general, it is better to utilize a spherical base as compared with other shapes and to locate the orifice close to distributor base. These changes tend to improve the robustness of the distributor in terms of providing even flow and phase distribution in different outlet branches w...

refrigerants that are used in refrigeration systems, cause environmental difficulties such as depletion of ozone layer and greenhouse effect. thus, we must find substitutes for such refrigerants, in this paper, the effect of refrigerant on the thermodynamics performance of refrigeration cycles are studied. to do this, a refrigerator that has designed for r12, is simulated. results show that pur...

Whilst there has been considerable research into the potential uses of digital games in the classroom, there has been less investigation into the educational value of Alternate Reality Games (ARGs). Unlike console or computer games, in ARGs the game-world is constructed through a combination of onand off-screen media, and is created and shaped through dynamic dialogue between the designers and ...

Over the last decade, Alternate Reality Games (ARGs), a form of narrative often involving multiple media and gaming elements to tell a story that might be affected by participants’ actions, have been used in the marketing and promotion of a number of entertainment related products such as films, computer games and music. This paper discusses the design, development and evaluation of an ARG aime...

Abstract The realm of alternate reality games is young, cutting-edge, with forms as varied and divergent as the evolving technologies that birth them. One of the distinguishing characteristics of augmented reality as a technology is the ability to register virtual obje...

Alternate Reality Games (ARG) can be used to reinforce classroom knowledge by encouraging collective learning practices and focusing on new media literacy skills. An ARG creates a game space from realworld locations by relying on information, both online and offline, to physically involve players in a game ‘space’. While the majority of large ARGs, to date, have been used as part of marketing c...

Knowledge of the solubility characteristics of an oiVrefrigerant mixture is important when analyzing the lubrication system behavior in refrigerant compressors since the solubility significantly affects the viscosity of the mixture. For an operating compressor, the lubricant is a mixture of oil and refrigerant and the viscosity of the mixture is a strong function of the refrigerant concentratio...
