Various Internet applications involve multiple parties and usually adopt a one-to-many communication paradigm (multicast). The presence of multiple receivers in a multicast session rises the problem of inter-receiver fairness. Transmitting with a rate which matches the slowest receiver will limit the throughput of other receivers and thus their satisfaction. A multi-rate mechanism where the rec...
In this paper we propose a mechanism for the allocation of pipeline capacities, assuming that participants bidding capacities do have subjective evaluation various network routes. The proposed is based on concept route–quantity pairs. Each participant defines limited number routes and places multiple bids, corresponding to quantities, each these assigns convex combination submitted bids partici...
So far we have seen two of the main inputs of an application performance model: its Performance-DNA and the usage volume. In my appreciation of modeling it is of crucial importance to be able to analyze the performance of both the application as whole and each of its transaction types individually. This is called Transaction Aware Performance Modeling or TAPM. So Performance-DNA preferably shou...
A tutorial study is performed on the capacity of multiple antenna wireless communication systems. Multiple antenna structures can be classified into single-input multiple-outputs (SIMO), multiple-inputs singleoutput (MISO), and multiple-inputs multiple-outputs (MIMO) systems. Assuming that the channel is known at receiver, capacity expressions are provided for each structure, under the conditio...
One major challenge in multiple sclerosis is to understand the cellular and molecular mechanisms leading to disease severity progression. The recently demonstrated correlation between disease severity and remyelination emphasizes the importance of identifying factors leading to a favourable outcome. Why remyelination fails or succeeds in multiple sclerosis patients remains largely unknown, main...
This paper is concerned with capacities of directsequence (DS) code-division multiple-access (CDMA) systems accommodating multiclass services with different transmission rates and bit error rates (BER’s). The capacities are expressed by inequalities to which the number of accepted calls of each class should conform. Those inequalities are necessary and sufficient conditions satisfying the requi...
The aim of the present study was to compare the aerobic and anaerobic power and capacity of elite male basketball players who played multiple positions. Fifty-five healthy players were divided into the following three different subsamples according to their positional role: guards (n = 22), forwards (n = 19) and centers (n = 14). The following three tests were applied to estimate their aerobic ...
