Hybrid Low Complex near Optimal Detector for Spatial Modulation

In our previous work maximum throughput in multi stream MIMO is analyzed by overcoming the inter antenna interference. To mitigate the Inter antenna interference spatial modulation can be used. Spatial Modulation(SM) aided MIMO systems are the emerging MIMO systems which are low complex and energy efficient. These systems additionally use spatial dimensions for transmitting information. In this paper a low complex detector based on matched filter is proposed for spatial modulation to achieve near maximum likelihood performance while avoiding exhaustive ML search since MF based detector exhibits a considerable reduced complexity since activated transmitting antenna and modulated amplitude phase modulation constellation are estimated separately. Simulation results show the performance of the proposed method with optimal ML detector, MRC and conventional matched filter methods

Rapid identification and susceptibility pattern of various Candida isolates from different clinical specimens in a tertiary care hospital in Western Uttar Pradesh

Background: Candida species are component of normal flora of human beings. Candidiasis is the commonest fungal disease affecting mucosa, skin, nails and internal organs. A variety of predisposing factors are known to cause candidiasis either by altering balance of normal microbial flora of the body or by lowering the host defence.Methods: A total of 90 specimens submitted in the department of microbiology were included in this study.  Identification of Candida species as well as antifungal sensitivity testing was performed with Vitek®2 compact (Biomerieux France) using Vitek2 cards for identification of yeast and yeast like organisms (ID-YST cards). Antifungal susceptibility testing was performed using Vitek2 fungal susceptibility card (AST YS01) kits respectively.Results: The distribution of the clinical samples were urine 53 (58.9%), sputum 14 (15.5%), blood 10 (11.1%), nail 6 (6.7%) and high vaginal swab 7 (7.8%). Among 90 clinical isolates, species obtained were C. tropicalis 53 (59%), C. albicans 23 (25.5%), C. glabrata 6 (6.7%), C. parapsilosis 4 (4.4%), C. krusei 2 (2.2%), C. pelliculosa 1 (1.1%), C. famata 1 (1.1%).Conclusions: Infections caused by non-candida albicans species have increased. Identification of Candida species and their antifungal susceptibility are important for the treatment of hospitalized patients with serious underlying disease

Performance evaluation of hybrid multilevel inverter with a high-frequency switching technique

Abstract This proposed work deals with the implementation of a single-phase topology with using hybrid for multilevel inverters. It is observed that the proposed structure improves the performance of the hybrid multilevel inverter with high-frequency switches for positive levels and reverse voltage with negative levels. This paper studies a novel construction for an asymmetrical hybrid single-phase multilevel inverter. This paper also studies the operation of multi level inverter under depreciating sources condition due to fluctuation in input. The PWM method, i.e. APOD and CO, has been incorporated into the simulation of single-phase 7-level, 9-level, and the 11-level hybrid inverter. These two methods are compared to one another and to standard methods in terms of THD for different values of the modulation index, and they are found to be superior. Overall loss of 50% of the THD is almost equal to rated output voltage, it is observed in cascaded multilevel inverters. The working and performance of the proposed model are simulated in MATLAB Simulink software and the results are discussed in detail

Not AvailableBacterial blight (BB) and fungal blast diseases are the major biotic constraints that limit rice productivity. To sustain yield improvement in rice, it is necessary to developed yield potential of the rice varieties by incorporation of biotic stress resistance genes. Tellahamsa is a well-adapted popular high yielding rice variety in Telangana state, India. However, the variety is highly susceptible to BB and blast. In this study, simultaneous stepwise transfer of genes through marker-assisted backcross breeding (MABB) strategy was used to introgress two major BB (Xa21 and xa13) and two major blast resistance genes (Pi54 and Pi1) into Tellahamsa. In each generation (from F1 to ICF3) foreground selection was done using gene-specific markers viz., pTA248 (Xa21), xa13prom (xa13), Pi54MAS (Pi54) and RM224 (Pi1). Two independent BC2F1 lines of Tellahamsa/ISM (Cross-I) and Tellahamsa/NLR145 (Cross-II) possessing 92% and 94% recurrent parent genome (RPG) respectively were intercrossed to develop ICF1—ICF3 generations. These gene pyramided lines were evaluated for key agro-morphological traits, quality, and resistance against blast at three different hotspot locations as well as BB at two locations. Two ICF3 gene pyramided lines viz., TH-625-159 and TH-625-491 possessing four genes exhibited a high level of resistance to BB and blast. In the future, these improved Tellahamsa lines could be developed as mega varieties for different agro-climatic zones and also as potential donors for different pre-breeding rice research.Department of Biotechnology, Government of India grant # BT/ PR11705/AGR/02/646/200
