We consider a simple model of cooperation among agents called Coalitional Skill Games (CSGs). This is a restricted form of coalitional games, where each agent has a set of skills that are required to complete various tasks. Each task requires a set of skills in order to be completed, and a coalition can accomplish the task only if the coalition’s agents cover the set of required skills for the ...

one dummy symbol has to be included for the sequence In this paper, a new generation and an information construction methods for a modulated orthogonal sequence are suggested the sequence is generated by only integer sums and modular techniques. The autocorrelation and cram correlation characteristics of the sequence are investigated via a new procedure. A modified sequence also having the orth...

This empirical study attempts to verify non-linearity relationships among three quality dimensions and user satisfaction from the DeLone and McLean IS Success Model. We use survey data from Agriculture integrated eXcellence systems (AgriX) users and a multiple regression analysis with dummy variables to analyze separately high and low performance groups. Results from the analysis suggest that i...

(a) Consider a random assignment α where every variable is set independently and with probability 12 to either 0 or 1. The probability that a 3-clause is not satis ed by α is 1 8 , which is the case when all its literals evaluate to zero. Therefore, the probability that a clause is satis ed is 1− 18 = 7 8 . Let Xi be the indicator variable for the event that clause i is satis ed by the random a...

In the last few years, increasingly kicks to the head were observed as a criminal offense. This study examined the influence of age, shoe type and kicking direction on the severity of head trauma. Male test persons were divided into two groups “Old” and “Young”. Both groups were equipped with light sneakers and combat boots. A standard laboratory crash dummy was used to simulate the victim’s bo...

Security-critical software is open to attacks by adversaries that disable its functionality. To decrease the risk, we propose an attack avoidance method for complicating process identification. The proposed method complicates identification based on process information by dynamically replacing the information held by a kernel with dummy information. Replacing process information makes identifyi...

This paper presents an exhaustive method to characterize the interconnect capacitances with taking the floating dummy-tills into account. Results of the case study with typical floating dummy-fills show that the inter-layer capacitances are also an important factor in the electrical consideration for the dummy-fills. An efficient field solving algorithm is implemented into the 3D finite-differe...

Abstract. Recently, we have presented a new practical method for upward crossing minimization [4], which clearly outperformed existing approaches for drawing hierarchical graphs in that respect. The outcome of this method is an upward planar representation (UPR), a planarly embedded graph in which crossings are represented by dummy vertices. However, straight-forward approaches for drawing such...

Over the past thirty years, economists have become increasingly interested in the labor market for professional sports. These studies have focused primarily on exploitation, the difference between marginal revenue product and salary, or discrimination, salary differentials based on race, or ethnic background. This paper attempts to combine both areas of research. that is, to explain the systema...
