FPGA Implementation of Turbo Decoder for LTE Standard
K. Kalyani,A. Sakthi Amutha Vardhini,S. Rajaram
Journal of Artificial Intelligence , 2013,
Abstract: The data rate of 100 Mbps will be supported by upcoming 3G Long Term Evolution (LTE) standard. In 20 MHZ of bandwidth, this data rate will be attained. For the arrival of high data rate of the 3G LTE systems, there is an essential requirement of turbo decoder implementation. In this work, Log-MAP algorithm based turbo decoder for LTE receiver is proposed. The Log-MAP based turbo decoder provides performance nearer to Shannon’s limit with reasonable computational complexity. The VHDL coding for parallel architecture of turbo decoder using Log-MAP algorithm for LTE is simulated and synthesized using Xilinx XC3S200-4ft256, Spartan 3 family and the results are verified with the manual calculation.
Using Crop Management Scenario Simulations to Evaluate the Sensitivity of the Ohio Phosphorus Risk Index  [PDF]

Journal of Environmental Protection (JEP) , 2017, DOI: 10.4236/jep.2017.82012
Abstract: Phosphorus (P) risk indices are commonly used in the USA to estimate the field-scale risk of agricultural P runoff. Because the Ohio P Risk Index is increasingly being used to judge farmer performance, it is important to evaluate weighting/scoring of all P Index parameters to ensure Ohio farmers are credited for practices that reduce P runoff risk and not unduly penalized for things not demonstrably related to runoff risk. A sensitivity analysis provides information as to how sensitive the P Index score is to changes in inputs. The objectives were to determine 1) which inputs are most highly associated with P Index scores and 2) the relative impact of each input variable on resultant P Index scores. The current approach uses simulations across 6134 Ohio point locations and five crop management scenarios (CMSs), representing increasing soil disturbance. The CMSs range from all no-till, which is being promoted in Ohio, rotational tillage, which is a common practice in Ohio to full tillage to represent an extreme practice. Results showed that P Index scores were best explained by soil test P (31.9%) followed by connectivity to water (29.7%), soil erosion (13.4%), fertilizer application amount (11.3%), runoff class (9.5%), fertilizer application method (2.2%), and finally filter strip (2.0%). Ohio P Index simulations across CMSs one through five showed that >40% scored <15 points (low) while <1.5% scored >45 points (very high). Given Ohio water quality problems, the Ohio P Index needs to be stricter. The current approach is useful for Ohio P Index evaluations and revision decisions by spatially illustrating the impact of potential changes regionally and state-wide.

Abstract: A Graph G is Super Strongly Perfect Graph if every induced sub graph H of G possesses a minimal dominating set that meets all the maximal complete sub graphs of H. In this paper we have analyzed the structure of super strongly perfect graphs in some Interconnection Networks, like Mesh, Torus, Hyper cubes and Grid Networks. Along with this investigation, we have characterized the Super Strongly Perfect ness in Mesh, Torus, Hyper cubes and Grid Networks. Also we have given the relationship between diameter, domination and co - domination numbers of Mesh, Torus, Hyper cubes and Grid Networks.

Abstract: Whole body protein catabolism results when the rate at which body protein is synthesized is less than the rate at which body protein is degraded. Insulin is among the many factors which regulate body protein metabolism. The lack of insulin associated with type 1 diabetes results in the loss of body protein, and insulin treatment reverses the loss of body protein resulting in increased lean body mass [1]. Several animal studies have demonstrated the importance of insulin in regulating the rate of protein synthesis particularly in muscle tissue (e.g., [2–7]). In contrast, studies of whole-body protein metabolism in adult humans with type 1 diabetes [8–13] and prepubertal children [14] have suggested that the primary effect of insulin is a reduction in the rate of protein degradation rather than a stimulation of the rate of protein synthesis. While provision of insulin to individuals with type 1 diabetes enhances the accretion of body protein mass, there are also data from adults [15] and adolescents females [16] suggesting that long-term insulin therapy also results in accumulation of body fat compared to nondiabetic individuals. The current study was undertaken to determine if the anabolic effect of insulin on protein metabolism could be enhanced by the concurrent provision of a diet enriched with the amino acid, leucine.In clinical studies, solutions of branched-chain amino acids have improved nitrogen balance in patients with surgical stress [17–19]. In patients with liver carcinoma, provision of branched-chain amino acids has been demonstrated to result in decreased morbidity and improved quality-of-life [20], reduced complications following surgery [21], and decreased length of hospital stay [22]. In healthy subjects, provision of essential amino acids in both young and old subjects results in a stimulation of the rate at which muscle protein is synthesized [23, 24]. In elderly subjects, enriching the essential amino acid supplement with additional leucine result

Journal of Biological Sciences , 2010,
Abstract: The present investigation was aimed at to test different Camellia sinensis (tea) extracts such as Magholai (I), 3 roses (II) and chakra gold (III) for their lactose reduction capability in milk with more lactose. Cow, goat, buffalo and two commercial milk samples such as KC and Star were tested for its lactose content. Among these buffalo milk as used as a control due to its high content of lactose (8 mL dL-1). Buffalo milk was treated by tea extracts I, II and III and 0.018, 0.018 and 0.042 mg dL-1 of lactose content were found. Its reveals that the lactose content of milk was well reduced by adding tea extracts and also its suggested peoples to have milk with herbal extracts (tea) who have gastrointestinal problems.
Simulation of perforated rectangular cantilever immunosensor for estimation of bacterial pathogens  [PDF]
J. Sakthi Swarrup, K. Govardhan, V. Velmurugan
Health (Health) , 2010, DOI: 10.4236/health.2010.211184
Abstract: Micro fabricated and multilayered perforated cantilever beam immunosensor was modeled using CoventorWare for the estimation of bacterial antigens of Bacillus Anthrax, Pseudomonas aeruginosa, Coryne Bacterium Diptheria and Treponema pallidum. A rectangular cantilever beam with perforations was simulated with dimensions as length-200 µm, width-10 µm and thickness-0.5 µm. Each perforation is rectangular with length-10 µm, width-5 µm and thickness-0.5 µm. The theoretical and FEM simulations were carried out with five immunoglobulin antibodies, IgA, IgD, IgE, IgG and IgM for the estimation of bacterial antigens. The effect of perforation in cantilever beam and molecular size of antibody and antigen on the performance of the sensor has been studied. The cantilever beam without perforation showed a deflection of 1.8 e + 02 µm whereas the cantilever beam with perforation showed an increase deflection of 1.9 e + 02 µm. With IgG, the difference between analytical and simulation values is positive and low especially with low molecular weight antigens Pseudomonas aeruginosa and Treponema pallidum. The low molecular weight IgG influences the antigen-antibody interaction more fvourably. The simulated perforated rectangular cantilever beam with IgG antibody is a more promising model for the fabrication of a sensor for the estimation of highly motile Pseudomonas aeruginosa and Treponema pallidum.
“Withered Tree” Concept Host, Achieved by Global Contraception and Abortion, Secondary to Fragmented Germ Cells, Agonizingly Reduced Endogenous Estrogen/Androgen, Defaulted Genomic Repertoire, Deranged Cell Metabolism, Metabolic Syndrome, Result in Failure of Pharmacological Therapeutics with Advanced Technologies  [PDF]

Abstract: Background: In spite of advanced technologies and drug discoveries, morbidity and mortality were undoubtedly increasing in the era of contraception and abortion. Aims: Altruistic correlation of increasing morbidity, mortality, with contraception, abortion was planned for. Methods: In 2012, a retrospective analysis of prevalence of mortality in 350 patients of 20 - 35 years, 35 - 50 years and >50 years from data collected between 2003 and 2012 by convenient, stratified random sampling, from community, hospital, and its association with contraception and abortion status was undertaken; simultaneously, serum estrogen levels obtained from 105 patients were analyzed. In 2014, randomly chosen 8 males, of the 3 age groups, from a different community, whose life partners had undergone sterilization, were assessed for their serum testosterone levels. Results: Contraception users exhibited 3 - 4 fold increased mortality [p < 0.0005] amongst 20 - 50 years and 6 fold increased mortality among >50 years [p < 0.0005]. Endogenous estrogen was reduced in 75% [p < 0.0005] of contraceptive users. Plasma testosterone was reduced in males observing contraception, to less than 50% of normal, e.g. 1.3 ng/ml; 66.6% contraception users aged 20 - 35 years had reduced [p < 0.0005] testosterone; 100% of male contraception users aged 36 - 70 years showed reduced testosterone [p < 0.0005]. Conclusion: The “withered tree akin host” concept is contraception, abortion, with smashed fragmentation of germ cells. Reduced endogenous estrogen, androgen [dried up, destroyed life factors] result in deranged cell metabolism, cell cycle, and defaulted genomic repertoire, leading to failure of all established pharmacological therapeutics, including advanced technologies which yield gratifying results in non contracepted people today and in every one, before the era of contraception; subsets of people, host with contraception, with destroyed life factors, behave helplessly, concerning therapeutic applications, compared with subsets of people, host without contraception, with intact genomic repertoire, God ordained Life factors, make a remarkable recovery. Contraception reversal replants the germ cells [germ cells destruction stops], hormones rejuvenate to 79.9% of age normal, and diseases abate with recovery.

Indian Journal of Dermatology, Venereology and Leprology , 2009,
Abstract: Background: Pemphigus disorders are a group of serious and potentially life-threatening diseases affecting skin and/or mucus membranes. Dexamethasone cyclophosphamide pulse (DCP) therapy has shown promising results in the management of these diseases. Aims: The objective of the study was to assess the outcome of DCP therapy in pemphigus. Methods: Pemphigus patients who had been treated with DCP therapy from 2001 to 2008 were prospectively and retrospectively analyzed. Results: A total of 65 pemphigus patients were enrolled. Male to female ratio was 1 : 1.82. Mean age of patients was 44.65 ± 11.85 years with a range of 14 to 73 years. Thirty two patients completed phase I, of which 28 (9 in phase II, 7 in phase III and 12 in phase III) were maintaining remission and four patients relapsed. Relapse was observed only in patients who discontinued or took irregular treatment. Six patients were declared cured of disease. Five patients died during phase I. Dexamethasone cyclophosphamide pulse therapy is not absolutely free from adverse effects. Most of the immediate side effects were expected, tolerable and did not pose any problem in continuing treatment. There was a slight increased incidence of weight gain, hypertension, diabetes mellitus, cataract and Cushingoid habitus, since most of our patients also received additional daily oral steroids. Also, there was a high incidence of secondary pyogenic infections of skin lesions and oral candidiasis during phase I. Staphylococcus aureus was the commonest bacteria isolated from the pus of skin lesions. Most of the alterations in laboratory parameters were transitory or correctable, and did not pose a problem in continuing therapy. Conclusions: DCP therapy was found to be effective in inducing and maintaining remission in pemphigus, provided the patients receive regular and complete treatment.
Defect Prevention Based on 5 Dimensions of Defect Origin
Sakthi Kumaresh,Baskaran Ramachandran
International Journal of Software Engineering & Applications , 2012,
Abstract: “Discovering the unexpected is more important than confirming the known [7]. In software development,the “unexpected” one relates to defects. These defects when unattended would cause failure to the productand risk to the users. The increasing dependency of society on software and the crucial consequences that afailure can cause requires the need to find out the defects at the origin itself. Based on the lessons learntfrom the earlier set of projects, a defect framework highlighting the 5 Dimensions (Ds) of defect origin isproposed in this work. The defect framework is based on analyzing the defects that had emerged fromvarious stages of software development like Requirements, Design, Coding, Testing and Timeline (defectsdue to lack of time during development). This study is not limited to just identifying the origin of defects atvarious phases of software development but also finds out the reasons for such defects, and defectpreventive (DP) measures are proposed for each type of defect. This work can help practitioners chooseeffective defect avoidance measures.In addition to arriving at defect framework, this work also proposes a defect injection metric based onseverity of the defect rather than just defect count, which gives the number of adjusted defects produced bya project at various phases. The defect injection metric value, once calculated, serves as a yardstick tomake a comparison in the improvements made in the software process development between similar set ofprojects
