Recent results on noncooperative space-time waveform optimization for Ad hoc networks are first reviewed. The optimization criterion is sum power minimization under a QoS constraint (decoupled capacity.) Noncooperative iterative minimum mean-square (IMMSE) algorithms are advocated here as a pragmatic solution to the QoS constrained optimization problem. Connections between IMMSE, time-reversal ...

In this paper we show how a fundamental result from information theory can be used to calculate the aggregate channel capacity in the uplink of an access point or a base station. The fundamental limits for this cell capacity provide an upper bound for any practically implementable multiple-access scheme. The capacity loss due to various implementation constraints is evaluated and a method for a...

The use of rectal balloon in radiotherapy of prostate cancer is shown to be effective in reducing prostate motion and minimizing rectal volume, thus reducing rectal toxicity. Air-filled rectal balloon has been used most commonly, but creates dose perturbation at the air-tissue interface. In this study, we evaluate the effects of rectal balloon-filling materials on the dose distribution to the t...

two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (sap) and irrigation management on seed and essential oil yields of cumin, as well as the impact of water quality on water holding capacity of sap. salinity had a negative effect on the amount of water absorbed by sap (335 and 59 g h2o per g sap, for distilled water and solution of 0.5% nacl...

This paper proposed a new weighted KNN data filling algorithm based on grey correlation analysis (GBWKNN) by researching the nearest neighbor of missing data filling method. It is aimed at that missing data is not sensitive to noise data and combined with grey system theory and the advantage of the K nearest neighbor algorithm. The experimental results on six UCI data sets showed that its filli...

Two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (SAP) and irrigation management on seed and essential oil yields of Cumin, as well as the impact of water quality on water holding capacity of SAP. Salinity had a negative effect on the amount of water absorbed by SAP (335 and 59 g H2O per g SAP, for distilled water and solution of 0.5% NaCl...

In this paper, we consider a wireless amplify-and-forward relay network with multiple source-relay-destination pairs transmitting concurrently over parallel channels and investigate the distributed power allocation problem within the framework of non-cooperative game theory. In order to combat the interference effect, each source node iteratively maximizes its own rate based on local informatio...

During recent years, foundry industry has witnessed an increasing awareness about the importance of the filling stage for the production of metallurgically sound and dimensionally stable castings. The metallurgical soundness of a casting is strongly influenced by the way the liquid metal flows through various parts of the gating system and fills the mould cavity. Owing to the importance of fill...
