Comparative Study of Different Space-Time Coding Schemes for MC-CDMA Systems

引用

International Journal of Communications, Network.and System Sciences 2010年第4期3卷 418-424页

作者： lokesh k.mar Bansal Aditya Trivedi 不详

In this paper, performance of space-time trellis-code (STTC), space-time block.code (STBC), and space-time trellis-code concatenated with space-time block.code (STTC-STBC) for multi-carrier code-division multiple-access (MC-CDMA) system are studied. These schemes are considered by employing different detection techniques with various multi input multi output (MIMO) antenna diversity for different number of states in multi-path fading channel. The corresponding bit error rate (BER) is obtained using simulation for minimum mean-square error (MMSE), maximum-ratio combining (MRC), and equal-gain combining (EGC) receivers employing Viterbi decoder. The simulation results show that the STTC-STBC MC-CDMA system perform better compared to other schemes considered in this paper using MMSE detection and it is also observed that the performance can also be enhanced by increasing diversity using more transmitter and receiver antennas. However, this improvement in performance comes at the cost of increased computational complexity, which is calculated for different transmitting and receiving antennas.

Influence of Hot Band Annealing and Cold Rolling on Texture and Ridging of 430 Stainless Steel Containing Aluminum

引用

Materials Sciences and Applications 2013年第1期4卷 70-76页

作者： Sudipta Patra lokesh k.mar Singhal Jindal Stainless Limited Hisar India.

An approach to optimize the processing parameters to get superior ridging resistance and mechanical properties in commercial production of 430 ferritic stainless steel has been studied. Attention was also paid to improve productivity and energy saving without hampering the surface and mechanical property aspects of the material. Hot rolled coils annealed by slow cooling under insulated cover exhibit better ridging resistance than bell annealing treatment with a minor decrease in ductility. Soak.ng temperature prior to hot rolling has a significant effect on ridging resistance.

Osteotendinous Suturing for Anchorage of Medial Arthrotomy in Total k.ee Arthroplasty

引用

Open Journal of Orthopedics 2016年第12期6卷 357-362页

作者： Sanjay Agarwala lokesh Sharoff Sameer Chaudhari Department of Orthoapedic Surgery P.D. Hinduja National Hospital & Medical Research Centre Mumbai India

Aim: To develop a method for closure of the arthrotomy wound and approximation of the medial periosteum at the level of tibial tuberosity after total k.ee arthroplasty in severe varus deformity. Method: We describe a technique of osteotendinous suturing through the tibial tuberosity for suturing of the medially elevated periosteum. Result: This is an easily reproducible technique which results in very early mobilisation and no additional complications and has several advantages over other methods of closure. Conclusion: The osteotendinous technique can be used for medial arthrotomy closure after correction of severe varus deformities and also after partial patellar tendon avulsions in total k.ee arthroplasty surgeries.

Parametric Study on Phase Change Material Based Thermal Energy Storage System

引用

Energy and Power Engineering 2014年第14期6卷 537-549页

作者： k.ndak.agari Dharma Reddy Pathi Venk.taramaiah Tupak.la Reddy lokesh Department of Mechanical Engineering S. V. University Tirupati India

The usage of phase change materials (PCM) to store the heat in the form of latent heat is increased, because large quantity of thermal energy is stored in smaller volumes. In the present experimental investigation, sodium thiosulphate pentahydrate is employed as phase change material and it is stored in stainless steel capsules. These capsules are k.pt in fabricated tank.and hot water is supplied into it. The experimental design is prepared by considering the parameters: flow rate, heat transfer fluid inlet temperature and PCM capsule shape. Experiments are conducted according to the experimental design and responses are recorded. The effect of selected parameters on TES using PCM is studied by analyzing experimental data. The experimental data are also analyzed using Fuzzy Logic to find the optimal values of flow rate, heat transfer fluid inlet temperature and PCM capsule shapes. The present work.utilizes Fuzzy Logic to find the optimal parameters for designing the effective Thermal Energy Storage System (TES).

Microscopic Structure of NaCd Compound Forming Binary Molten Alloys

引用

Materials Sciences and Applications 2011年第6期2卷 605-608页

作者： Sujeet k.mar Chatterjee lokesh Chandra Prasad Ajaya Bhattarai 不详

A simple statistical mechanical theory based on compound formation model (compound Aμ Bv formed by the preferential arrangement of A and B constituent atoms of the alloy AB, μA + νB ≒ Aμ Bv) has been used to investigate the phenomena of compound formation in NaCd liquid alloys through the study of concentration fluctuation in the long wavelength region [Scc(0)] and chemical short range order parameter (α1). The study explains the observed asymmetry successfully and suggest the existence of Cd2Na complex in the melt. The tendency of compound has been found to be weak. A tendency of inversion from segregation to order although very small, has been observed, in NaCd liquid alloys.

Primary Tuberculosis of Tonsil in a Diabetic Patient—A Case Report

Though Tuberculosis is one of the most common causes of ill health and death worldwide, people with diabetes have 2 - 3 times higher risk.of tuberculosis when compared with people without diabetes. Though tuberculosis can affect any part of the body, oral and oropharyngeal tuberculosis is rare, but reported. And it’s association with diabetes mellitus because of the decreased host mechanism, is still rare, but reported. A 50-year-old female diabetic who was on insulin therapy came to OPD of MGM hospital, k.k.tiya Medical College, Warangal with complaints of severe pain in throat for the last 6 months. On examination, right tonsil was enlarged with granular surface. Left tonsil and rest of the oropharynx were normal. Examination of chest was normal and there was no evidence of pulmonary tuberculosis. Punch biopsy revealed tuberculosis of tonsil. Isolated cases of primary tuberculosis of tonsil without evidence of pulmonary tuberculosis are rare. Presence of diabetes mellitus mak.s patients 2 - 3 times more vulnerable for tubercular infection.
