In the MIMO-OFDM systems, the traditional methods of multi-user detection have some limitations in the rank-deficient scenarios, where the number of supported users exceeds the number of receiver antennas. The multiuser detection (MUD) based on the genetic simulated annealing algorithm (GSAA) is proposed for the rankdeficient problems in the multi-user MIMO-OFDM system. The simulation results s...

Introduction: At high magnetic field strengths (≥3T) the RF wavelength becomes smaller than the sample size, making transmit magnetic field (B1) inhomogeneity more prominent. RF-shimming [1] and Transmit SENSE [2] have been proposed as methods to minimize this inhomogeneity. To take advantage of these methods it is important to accurately map the B1 field. Saturation prepared with 2 RApid Gradi...

Due to human activities huge amount of organic wastes are simply dumped in the environment creating disposal and pollution problems. Suitable and sustainable utilization of these wastes is vermicomposting which converts wastes in to wealth. In the present study, 1:1 proportion (wt./wt.) of vegetable market waste (VMW) and press mud (sugar industry waste) mixture have been used for vermicomposti...

sore has appeared among the class of people (not necessarily poor) who, during a heavy rainy season, walked in mud and worked in marshy localities, barefooted. Forty-five inches of rain, mud and marshy conditions?and Naga sore were not previously known to this place. The same thing happened in Benares last summer, when heavy rainfall flooded the area, resulting in mud and marsh so that Naga sor...

Conventional Multi-User Detection (MUD) algorithms for the Multi-Input, Multi-Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system fail to consider the detection performance and algorithm complexity simultaneously. To address this problem, a new Joint Intelligent MUD (JI-MUD) algorithm that aims to improve the MUD performance of the MIMO-OFDM system and to reduce the complexity ...

Mud therapy is a system of naturopathic medicine where treatment given using various forms mud. Hence, the present study aims to evaluate physiological effects simultaneous application cold mud pack over abdomen and eyes by determining cardiovascular autonomic parameters participants. 30 healthy volunteers were recruited for study. All subjected two sessions treadmill run up 10 minutes subseque...

In this paper, we propose a novel low complexity minimum mean-squared based multiuser detection (MMSE MUD), which employs partial but essential information of the interferences, in a multichannel TDMA system. The new approach begins with the determination of the effective channel length of the interferences based on the information theoretic criteria. We then truncate the channel taps according...

A generically applicable hybrid MultiUser Detector (MUD) concept is proposed by appropriately activating different MUDs in consecutive turbo iterations based on the Mutual Information (MI) gain. It is demonstrated that the proposed hybrid MUD is capable of approaching the optimal Bayesian MUD’s performance despite its reduced complexity, which is at a modestly increased complexity in comparison...

The fate of phosphate added to fishponds and the inorganic processes of phosphorus fixation were studied in Israel. Conditions in these ponds are different from those of the more humid climatic zones in having alkaline water and high calcium content. In these condi tions most of the phosphorus added is precipitated as Ca3(P04)2. rctical aspects of this are discussed. The quantitative theobottom...
