This paper studies optimal long-term capacity strategies when there exist markets for capacity options. The essential ingredients of the problem derive from the strategic interaction of contract markets with spot markets. This interaction provides the foundation for the short-term pricing and contracting strategies for market participants. Sellers in this market can sign long-term (e.g., forwar...

We have evaluated the information theoretical performance of variable rate adaptive channel coding for Rayleigh fading channels. The channel states are detected at the receiver and fed back to the transmitter by means of a noiseless feedback link. Based on the channel state informations, the transmitter can adjust the channel coding scheme accordingly. Coherent channel and arbitrary channel sym...

To increase the transmission rate without bandwidth expansion, the multiple-input multiple-output (MIMO) technique has recently been attracting much attention. The MIMO channel capacity in a cellular system is affected by the interference from neighboring co-channel cells. In this paper, we introduce the cellular channel capacity and evaluate its outage capacity, taking into account the frequen...

Multiple transmit and multiple receive antennas system, referred to Multiple-Input Multiple-Output (MIMO) system, is known to achieve large channel capacity without bandwidth expansion. In this paper, we propose a simplified ML detection scheme for MIMO system which has reduced computational complexity compared to Maximum Likelihood (ML) detection scheme. According to simulation results, the bi...

In this paper, a model for hybrid transmission expansion planning (TEP) and reactive power planning (RPP) considering demand response (DR) model has been presented. In this study RPP considered by TEP for its effects on lines capacity and reduction of system expansion costs. On the other hand the expansion of the transmission system is an important subject, especially dealing with the new i...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...
