Optimized OFDM Model Using CMA Channel Equalization for BER Evaluation

Orthogonal Frequency Division Multiplexing (OFDM) is a type of Multicarrier Modulation (MCM) technique in which entire bandwidth is divided into large number of small sub-carriers and each subcarrier is transmitted parallel to achieve higher data rates. It has various applications like Digital Audio Broadcasting (DAB), Digital Video Broadcasting (DVB) and wireless LAN.OFDM technique is widely used in wireless communication system because of its very high data rate. The performance of FFT based OFDM system using Linear and cyclic channel coding and Constant Modulus Algorithm (CMA) equalizer is simulated using simulink model. The BER saving using the optimized proposed model with both linear and cyclic channel coding along with CMA equalizer is evaluated. The proposed work using cyclic channel coding with QPSK/QAM modulation and CMA as channel equalization under AWGN channel results in 52.6% and 96.3% BER reduction as compared to conventional OFDM model without channel coding, channel equalization and channel fading. So, CMA equalizer is used to enhance the performance of OFDM system

Systemic Review: Sexual Dysfunction in Women with type 2 Diabetes Mellitus

Diabetes would not just have a high blood glucose level in the individual body, yet these days diabetes likewise goes with numerous other organic issues like hypertension, feeble the myocardial layer working, sexual broke, and so on. These are some real issue which is these days joined by diabetes to a person’s body. Guys are for the most part being determined to have the sexual broke issue, guys, as well as experience a sexual broke issue. As similarly we may see less clinical examinations, including sexual broke issues looked for the sort two diabetic ladies. The primary goal of this article is to illuminate the situation that females proceed with much trouble with regards to the sexual broke Complication that might be physiological or neurotic if there should arise an occurrence of sorting two diabetes in ladies. It chiefly involves the useful extent of females like sexual drive, excitement, vaginal grease, Orgasm and general fulfilment space. Talking about the treatmentaccess of the ailment in the analyti way for it, Diabetes essentially hinders the sexual execution of Diabetic Women. Determinants of sexual ability incorporate age and extent of diabetes

Surface Functionalization of TiO2 with Plant Extracts and their Combined Antimicrobial Activities Against E. faecalis and E. Coli

Abstract: The aim of this study is to enhance the antibacterial activity of TiO2 by pure plant extracts of Bauhinia variegata and Tinospora. cordifolia by making a composite of plant extract and TiO2. Plant extracts, TiO2 and plant extracts/TiO2 composites were investigated against two bacterial strain Enterococcus faecalis and Escherichia coli. X-ray diffraction investigations have confirmed the presence of TiO2 nanoparticles in the plant extract/TiO2 nanocomposites. UV-visible investigations have shown an enhanced photocatalytic activity of plant extract/TiO2 nanocomposites compared to that of pure TiO2 and pure plant extract. Plant extract/TiO2 nanocomposites have shown various level of antibacterial activity on different test microorganisms. The highest antibacterial potentiality expressed in terms of zone of inhibition (ZOI) in mm was exhibited by the aqueous extract of Bauhinia variegata /TiO2 (45 mm against Enterococcus faecalis and 30 mm against Escherichia coli) and benzene extract of Tinospora cordifolia /TiO2 (26 mm) nanocomposites. This is the first study on these types of bio-nano composite materials and it serves as basis for further research on these types of composite materials as a potent antibacterial agent

Chemical Beneficiation of Low Grade Coal - A Review

India is having large reserves of low grade coals. The use of low-grade coal in various industries like power plants, metallurgical plants, cement units etc. leads to environ-mental pollution because of generation of large amount of solid and gaseous pollutants. Therefore, it is of impor-tance paramount to clean the coal before its utilization. There are a number of upgrading technologies to produce clean coal. The current paper reviews demineralization aspects by physical and chemical beneficiation of high ash and/ sulfur containing coal.Physical beneficiation of coal is not very effective in separation of the finely dispersed minerals, whereas chemical beneficiation uses expensive reagents and leads to generation of large amount of waste-water which needs to be purified before discharge. Thus, a combined approach consisting of physical and chemical cleaning of coal appears to have a potential for. signifi-cant reduction of ash with less investment while generat-ing less polluting wastewater

Solvent extraction and separation of copper and zinc from a pickling solution

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase comprising of 30% Versatic 10 acid at the equilibrium pH of 5.0 using the phase ratio of 1:1 whereas, zinc extraction was noticed at above pH 5.0. On the other hand the pH0.5 values were 3.5 and 4.6 for zinc and copper respectively with 20% Cyanex 272. The difference in pH0.5 value of 1.10 indicated the possible separation of Zn and Cu. By McCabe Thiele diagram number of stages required for the counter current extraction of copper and zinc has been determined for both the solvents. The stripping study showed that 1 mol/L H2SO4 was sufficient to strip metal ions in a single contact from each of the extractant
