Cooperative agreements among firms to coordinate R&D investments and share knowledge or coordination among nations to reduce trade barriers or to provide global public goods usually proves difficult due to free-rider incentives. In this paper, we propose a sharing scheme for the distribution of the gains from cooperation for games with externalities and heterogeneous players in order to mitigat...

In Part II of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p greater than .05), increased Hb and PCV % (p greater than .05), and lowered HR at rest and in warm-up exercise (p greater than .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer...

Peer-to-Peer (P2P) applications have recently seen an enormous success and have reached millions of users. The main reason of this success is the anonymity the users enjoy. However, as recent experiences with P2P networks show, this anonymity offers an opportunity to exploit the network like free-rider, virus spread, malicious file spread etc. The problem of securing hosts on P2P network while ...

Inspired by nakashi Taiwanese street performance culture, Movable Party creates a bustling public and streetside vibrancy in the decentralized metropolis of Los Angeles. The system consists of three stationary bicycles, each equippe...

Lately, modeling and optimizing endurance performance has become popular. Optimal strategies have been calculated for running as well as for cycling. Since most of these studies are of theoretical nature, we performed a series of experiments to determine whether race performance can actually be improved using mathematical optimization in a realistic scenario. The optimal strategy was based on t...

We compared anteroposterior and mediolateral range of motion and velocity of the center of pressure (COP) on the horse's back between riders without disabilities and riders with cerebral palsy. An electronic pressure mat was used to track COP movements beneath the saddle in 4 riders without disabilities and 4 riders with cerebral palsy. Comparisons between rider groups were made using the Mann-...

We propose a new shipboard crane configuration for offloading cargo in open seas. We show that the “Maryland Rigging” crane of ship’s configuration, used in association with a friction control mechanism, provides a very effective method for reducing load pendulation caused by the motion of the crane in the roll direction. The effectiveness of the control technique is obtained by comparing the p...
