It is shown that the work function algorithm for the 2-evader problem has competitive ratio m ? 2 for all metric spaces with m points. This settles the k-server conjecture for metric spaces with k+2 points.

An online domain-independent competitive gaming system, called JOYCE, was devised to engage students in drill-and-practice exercises. In this paper, theories underpinning the system design are explained. As in the system students are allowed to compete with others in a face-to-face situation, and in network situations where an opponent’s identify is revealed or concealed, a preliminary study wa...

In Part 11 of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p > .05), increased Hb and PCV % (p > .05), and lowered HR at rest and in warm-up exercise (p > .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer, at standardised power output, s...

The activity of every substance I inhibiting an enzymatic reaction can be approximately evaluated by the index PI50. This paper describes a simple and fast method of estimate and/ or determination of this index. The method is based on the linearity of the dependence of the ratio of reaction rates of uninhibited and inhibited reaction vs. concentration of the inhibitor at constant initial substr...

This paper aims to select the evaluation indexes of high-level Wushu team based on the literature, questionnaires, AHP and mathematical statistics so as to build a Performance Management Evaluation Index System. The research findings are as follows: high-level Wushu team Performance Management Evaluation Index System consists of four first-class indexes including the sports team training manage...

This paper studies coalition formation, payoff division and expected payoffs in a ”divide the dollar by majority rule” game with random proposers. A power index is called self-confirming if it can be obtained as an equilibrium of the game using the index itself as probability vector. Unlike the Shapley value and other commonly used power indices, the nucleolus has this property. The proof uses ...

Efficient learning and categorization in the face of myriad categories and instances is an important challenge. We investigate algorithms that efficiently learn sparse but accurate category indices. An index is a weighted bipartite graphs mapping features to categories. Given an instance, the index retrieves, scores, and ranks a set of candidate categories. The ranking or the scores can then be...

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...

Developing a robust, product platform architecture brings an important competitive advantage to a company. The major benefits are reduced design effort and time-to-market for future generations of the product. This paper describes a step-by-step method that aids companies in developing such product platform architectures. Using the concept of specification ‘‘flows’’ within a product development...

In this paper we present a compact structure to index semistatic collections of MBRs that solves range queries while keeping a good trade-off between the space needed to store the index and its search efficiency. This is very relevant considering the current sizes and gaps in the memory hierarchy. Our index is based on the wavelet tree, a structure used to represent sequences, permutations, and...
