Energy efficient intelligent routing in WSN using dominant genetic algorithm

In the current era of wireless sensor network development, among the various challenging issues, the life enhancement has obtained the prime interest. Reason is clear and straight: the battery operated sensors do have limited period of life hence to keep the network active as much as possible, life of network should be larger. To enhance the life of the network, at different level different approaches has been applied, broadly defining the proper scheduling of sensors and defining the energy efficient communication. In this paper heuristic based energy efficient communication approch has applied. A new development in the Genetic algorithm has presented and called as Dominant Genetic algorithm to determine the optimum energy efficient routing path between sensor nodes and to define the optimal energy efficient trajectory for mobile data gathering node. Dominancy of high fitness solution has included in the Genetic algorithm because of its natural existence. The proposed solution has applied the connection oriented crossover and mutation operator to maintain the feasibility of generated solution. The proposed solution has applied with various simulation experiments under two different scenarios: in first case energy efficient routes among the sensors have explored to deliver the information from source sensor to the sink node and in second case, energy efficient route among all local data hubs for mobile data gathering node has obtained. The proposed solution performances have been analyzed quantitatively and analytically. It has observed with various experimental results that proposed method not only has delivered the better solution but also has faster convergence and high level of reliability in compared to conventional form of Genetic algorithm

Mental Illness Stigma, Mental Health Literacy, And Psychological Help-Seeking In A Rural Population

This study assessed relationships between mental illness stigma (public stigma (Vogel, Wade & Ascheman, 2009) and private stigma (Vogel, Wade & Haake, 2006)), mental health literacy (Mental Health Literacy Survey (MHLS; Epps et al. 2007) and Symptom Recognition Scale, (SRS)), and psychological help-seeking (Attitudes towards Seeking Professional Psychological Help Scale and Intentions via LSHS) in a rural population. Two-hundred three adults living in rural and urbanized counties within a rural Midwestern state completed paper and online surveys. Stepwise hierarchical regression analyses showed that private stigma, mental health literacy, and previous help-seeking behavior predicted attitudes towards seeking professional help while symptom recognition and previous help-seeking behavior were important predictors of intentions to seek help, relative to other factors. Mental health literacy did not moderate the relationships between stigma variables and help-seeking variables and previous help-seeking did not act as a mediator in the relationship between mental health literacy variables and help-seeking variables. Public stigma did not contribute significant variance to help-seeking attitudes and intentions. Support for private stigma reduction was garnered. Overall, findings support the role of mental health literacy in improving intentions to seek professional help

Design Approach to Implementation Of Arbitration Algorithm In Shared Bus Architectures (MPSoC)

The multiprocessor SoC designs have more than one processor and huge memory on the same chip. SoC consists of hardware cores and software cores ,multiple processors, embedded DRAM and connectors between cores .A wide range of MPSOC architectures have been developed over the past decade. This paper surveys the history of various On-Chip communication architectures present in the design of MPSoC. This acts as a primary factor of overall performance in complex SoC designs. Some of the various techniques that have driven the design of MpSoC has been discussed. Dynamically configurable communication architectures are found to improve the system performance. Currently On-chip interconnection networks are mostly implemented using shared buses which are the most common medium. The arbitration plays a crucial role in determining performance of bus-based system, as it assigns priorities, with which processor is granted the access to the shared communication resources. In the conventional arbitration algorithms there are some drawbacks such as bus starvation problem and low system performance. The bus should provide each component a flexible and utmost share of on-chip communication bandwidth and should improve the latency in access of the shared bus. The performance of SoC is improved using the probabilistic round robin algorithm with regard to the parameters, latency.Thus in this paper various issues related to bus arbitration related to design of MPSoC is analysed

On the modulation of low frequency Quasi-Periodic Oscillations in black-hole transients

We studied the properties of the low-frequency quasi-periodic oscillations detected in a sample of six black hole candidates (XTE J1550-564, H 1743-322, XTE J1859+226, 4U 1630-47,GX 339-4, XTE J1650-500) observed by the Rossi XTE satellite. We analyzed the relation between the full width half maximum and the frequency of all the narrow peaks detected in power density spectra where a type-C QPO is observed. Our goal was to understand the nature of the modulation of the signal by comparing the properties of different harmonic peaks in the power density spectrum. We find that for the sources in our sample the width of the fundamental and of the first harmonic are compatible with a frequency modulation, while that of the sub-harmonic is independent of frequency, possibly indicating the presence of an additional modulation in amplitude. We compare our results with those obtained earlier from GRS 1915+105 and XTE J1550-564.Comment: 8 pages, 3 figures, accepted for publication in Monthly Notices of the Royal Astronomical Society Main Journa

Study on pattern of gynaecological malignancies at Saveetha Medical College and Hospital, Tamil Nadu, India

Background: The burden of malignancy and deaths due to it are rising worldwide. In women gynaecological malignancies are among the most common cancers. This study was undertaken to study the pattern and relative frequencies of gynaecological malignancies among women admitted in the Department of Gynaecology, at Saveetha Medical College and Hospital, Tamil Nadu.Methods: This is a retrospective observational study done at the department of Saveetha Medical College and Hospital over a period of two years from September 2015 to September 2017. Case records of women admitted in the Department of Gynaecology and diagnosed to have gynaecological malignancy were retrieved from the department of medical records. Information regarding demographic details, site of malignancy, histopathology of malignancy was analysed and expressed as percentages.Results: During the study period 49 cases of gynaecological malignancies were reported. Out of 49 cases, 36 cases were cancer cervix, followed by 7 cases of ovarian malignancy and 6 cases of cancer of uterine corpus. The mean ages of cancer cervix, ovary and corpus uteri were 51.1, 53.3 and 47.2 years respectively. All women were multiparous in the study. One third of women were premenopausal. Women with cancer cervix and corpus uteri commonly presented with irregular bleeding, post-menopausal bleeding and white discharge per vaginum. Ovarian cancers presented commonly with abdominal pain and distension. Squamous cell carcinoma of cervix was the commonest histopathology seen. Adenocarcinoma and epithelial cancer was the commonest histopathology seen in endometrial and ovarian cancer respectively.Conclusions: Cancer cervix was the commonest gynaecological malignancy in the study population followed by ovarian and uterine malignancies

The Impact of External Contexts on Alliance Governance in Biotech–Pharmaceutical Firm Alliances

The interest in strategic alliances has increased over the years, especially in high tech global industries such as biotechnology, as firms seek to gain access to needed resources, expertise, and knowledge for developing and commercializing new products and technologies. The governance structure of these alliances, which is an important consideration in understanding alliance formation and performance, is influenced by both external and internal contexts of the alliance partners. However, evidence from prior research has been inconclusive regarding the impact of external contexts on alliance governance selection. To better understand this impact, we simultaneously examine three key partner external contexts - international, technological, and social contexts, and their influence on biotechnology-pharmaceutical alliance governance structure selection. Using a sample of 389 alliances formed during the six-year period 1995 through 2000, we find that the international context, specifically national cultural distance between alliance partners, and the social context, specifically credibility of the biotechnology partner in the alliance network, influence governance structure selection. We offer implications of our findings for theory, future research, and management practice

A correlation of clinical, hormonal and ultrasonography features of polycystic ovarian syndrome among adolescent and reproductive age group women attending OPD in Navodaya medical college

Background: Polycystic ovarian syndrome is the most common complex endocrine disorder in women of reproductive age. It is characterized by an array of clinical, endocrinal and metabolic manifestation. Aim of this study was to examine the correlation between clinical, hormonal and ultrasonography features in women diagnosed as polycystic ovarian syndrome. Methods: A cross sectional study of 100 reproductive age group women who had irregular cycles and polycystic ovarian morphology on ultrasound. Data about the menstrual history and anthropometric measurements were collected. Clinical observations were like hirsuitism and acanthosis nigricans was noted. Results: In all 100 PCOS women were studied and analysed. The mean age was 24.27(±5.64), mean BMI was 26(±4.8). Among the PCOS women 82% had oligo menorrhoea, 38% had hirsuitism and LH:FSH ratio deranged in 37% cases. The association between women having oligomenorrhoea and obesity with PCO morphology on scan was statistically significant. Conclusions: Young women who are diagnosed as dysregulated PCO are at a high risk to develop PCOD and long term sequel such as diabetes, hypertension and infertility. Lifestyle modification is advisable for managing symptoms and preventing long term complications and have a quality life

Bacteriological Profile of Surgical Site Infection and Antibiotic Susceptibility Pattern in Tertiary Care Hospital

INTRODUCTION: Surgical site infections are one of the most common nosocomial infections accounting for 38% of all infections in post surgical patients. The aim is to find out the incidence rate of surgical site infection in patients undergoing surgery in the departments of Surgery, Orthopedics,Obstetrics and Gynaecology and its antibiotic susceptibility pattern. MATERIALS AND METHODS: Under sterile aseptic precautions, Pus exudate was collected using two sterile cotton swabs for aerobic culture and for anaerobic culture pus was aspirated in a sterile syringe and inoculated onto Blood agar and Macconkey agar, Nutrient agar and Robertson cooked meat media. The samples were processed as follows, Direct microscopic examination of Gram stained smear, preliminary identification by colony morphology,Biochemical test for characterization of species and Antibiotic sensitivity testing. RESULTS: Out of 220 cases,137 were male patients and 83 were female patients with infection rate more in Male. Clean wound were 20, Clean contaminated wound were 71, Contaminated wound were 110 and Dirty wound were 19, with infection rate more in Contaminated wound. Elective surgeries were 98 and Emergency surgeries were 122 with infection rate more in Emergency surgeries. Culture positive were 153 and Culture negative were 67. In the culture positive cases, aerobic were 146 and anaerobic were 7. Among the aerobic isolates Staphylococcus was the most common Gram positive organisms isolated and klebsiella pneumoniae was the most common Gram negative organism isolated. CONCLUSION: Knowledge about Surgical site infection will help surgeon in diagnosis and treatment, early detection and intervention is a prerequisite in surgical patients. Although surgical wound infections cannot be completely eliminated, a reduction in infection rate to a minimum level could have significant benefits, by reducing burden to patients and their families. Intervention aimed at reducing Surgical site infection would provide cost savings and improve the efficiency of health care system

Realistic Tight Binding Model for the Electronic Structure of II-VI Semiconductors

We analyze the electronic structure of group II-VI semiconductors obtained within LMTO approach in order to arrive at a realistic and minimal tight binding model, parameterized to provide an accurate description of both valence and conduction bands. It is shown that a nearest-neighbor $sp^3d^5$ model is fairly sufficient to describe to a large extent the electronic structure of these systems over a wide energy range, obviating the use of any fictitious $s^*$ orbital. The obtained hopping parameters obey the universal scaling law proposed by Harrison, ensuring transferability to other systems. Furthermore, we show that certain subtle features in the bonding of these compounds require the inclusion of anion-anion interactions in addition to the nearest-neighbor cation-anion interactions.Comment: 9 pages, 9 figure
