In the obnoxious facility game, a location for an undesirable facility is to be determined based on the voting of selfish agents. Design of group strategy proof mechanisms has been extensively studied, but it is known that there is a gap between the social benefit (i.e., the sum of individual benefits) by a facility location determined by any group strategy proof mechanism and the maximum socia...

Himalayan dock (Rumex nepalensis) was evaluated for forage value and antinutrients under three, five and seven weeks cutting intervals in the temperate environment. Dry matter (DM) content was measured for each cutting interval. Forage quality parameters such as Crude Protein (CP), Acid Detergent fiber (ADF), Neutral Detergent Fiber (NDF), Calcium (Ca) and Phosphorus (P) were analyzed. Plants w...

447 This discussion paper surveys the current state of software for scientific and engineering applications, and the foreseeable evolutions. It argues that a serious change in the attitude of scientists and engineers is necessary in order to master the growth of problem size. The discussion includes aspects of methodology, tools and languages ; we feel that much progress is needed in all three ...

The quality of my daily awakening ritual changed dramatically a few months ago when I was exposed to the Timex Nature Sounds alarm clock. Prior to this, it had never occurred to me to use something other than the traditional buzzer-type alarm clock that I had had since 1986 because “it still worked.” While this was true, it worked by emitting a loud obnoxious sound that stimulated a fight or fl...

According to WHO, Pharmacovigilance activities are done to monitor detection, assessment, understanding and prevention of any obnoxious adverse reactions to drugs at therapeutic concentration on animal and human beings. However, there is also a growing focus among scientists and environmentalists about the impact of drugs on environment and surroundings. The existing term 'Ecopharmacology' is t...

In this paper we consider the following obnoxious facility location problem: given a set S of n points in the plane, and two special points a and b, find the 1-corner polygonal chain (also known as boomerang) connecting a and b such that its minimum distance to S is maximized. In other words: find the widest empty polygonal chain of two edges having extremes anchored at a and b. We present a ne...
