A Power Quality Improvement for Microgrid Inverter Operated in Grid Connected and Grid Disconnected Modes
The renewable energy based distributed generators (DGs) will plays a dominant role in electricity production. A micro grid consists of clusters of load and distributed generators that operate as a single controllable system. The interconnection of the DG to the utility/grid through power electronic converters has raised concern about safe operation and protection of the equipments. The main objective of this paper is too focused on the power quality improvement in micro grid. In the distributed power system, the increased infiltration of nonlinear loads and power electronic interfaced distribution generation systems creates power quality issues such as voltage unbalance, frequency regulation and harmonic elimination
Autism Spectrum Disorder: The Dilemma of Untimely Recognition, Intervention and Diagnostic Scales Obtainable at Indian Sub-continent
The increasing prevalence of Autism Spectrum Disorder makes it as considerable issue worldwide. Recent studies addresses the hot topic of Mirror Neuronal System (MNS) confers behind the ASD. However, the cause is uncertain, Indian population prone to varied prenatal and postnatal factors of the condition. Indian parents and professional still be at the initial awareness phase of the spectrum. Years of delay in identification and intervention while comparing with world standards due to various Indian socio-economic and socio-cultural factors. Less availability of screening and diagnostic tools headed to relay on culturally irrelevant and expensive international tools. Government funded research initiatives developed ISAA, INDT-ASD, CASI and AIIMS Modified INDT-ASD as culturally relevant indigenous tools and available on practice. So far, the tools have their own advantages and limitations, requires further research and progression. Owing to scarcity of trained professionals for a wide population range, home based parent-mediated therapies be the most preferred mode of therapy. However, the therapeutic options vary with people. The study aimed to ascertain the present Indian scenario, look upon the awareness about the condition, availability of screening and diagnostic facilities, the early identification and timely intervention program. In addition, the study briefly confers the biological and clinical background of ASD.
A Study on Co – odd (even) Sum Degree Edge Domination Number in Graphs
يقال إن المجموعة المهيمنة على الحافة من الرسم البياني هي مجموعة مهيمنة على حافة المجموع الفردي (الزوجي) (osded (esded) - set) من G إذا كان مجموع درجة جميع الحواف في X هو رقم فردي (زوجي). المجموع الفردي (الزوجي) لدرجة الحافة لرقم الهيمنة هو الحد الأدنى من الكاردينالية المأخوذة على جميع المجموعات المهيمنة على حافة المجموع الفردي (الزوجي) من G ويتم تعريفه على أنه صفر إذا لم يكن هناك مثل هذا المجموع المهيمن على حافة المجموع الفردي (الزوجي) في G. في هذا البحث ، تم توسيع مفهوم هيمنة درجة المجموع الفردي (الزوجي) على المجموعة المهيمنة المشتركة E-T للرسم البياني G ، حيث T هي مجموعة مهيمنة على الحافة من G. . تم تعريف المعلمات المقابلة لCo-الفردي (الزوجي) مجموع درجة الحافة المهيمنة على مجموعة ، و Co - الفردي (الزوجي) مجموع درجة الهيمنة على الحافة و Co- الفردي ( الزوجي) مجموع درجة قيمة هيمنة الحافة. علاوة على ذلك ، تم العثور على القيم الدقيقة للمعلمات المذكورة أعلاه لبعض الفئات القياسية من الرسوم البيانية. يتم الحصول على حدود رقم هيمنة حافة المجموع Co- الفردي (الزوجي) من حيث مصطلحات الرسم البياني الأساسية. تم تميز المجموعات المهيمنة على حافة المجموع Co - الفردي (الزوجي). كما تتم دراسة العلاقات مع معلمات هيمنة الحافة الأخرى. An edge dominating set of a graph is said to be an odd (even) sum degree edge dominating set (osded (esded) - set) of G if the sum of the degree of all edges in X is an odd (even) number. The odd (even) sum degree edge domination number is the minimum cardinality taken over all odd (even) sum degree edge dominating sets of G and is defined as zero if no such odd (even) sum degree edge dominating set exists in G. In this paper, the odd (even) sum degree domination concept is extended on the co-dominating set E-T of a graph G, where T is an edge dominating set of G. The corresponding parameters co-odd (even) sum degree edge dominating set, co-odd (even) sum degree edge domination number and co-odd (even) sum degree edge domination value is defined. Further, the exact values of the above said parameters are found for some standard classes of graphs. The bounds of the co-odd (even) sum degree edge domination number are obtained in terms of basic graph terminologies. The co-odd (even) sum degree edge dominating sets are characterized. The relationships with other edge domination parameters are also studied
Effect of Bio sulphur granules (BSG) as fertilizer ingredient on different fractions of sulphur in calcareous soil cultivated with blackgram (Var.VBN-8)
The purpose of this study was to examine the various sulphur (S) fractions in experimental pot calcareous soil treated with Bio sulphur granules (BSG) in order to assess the impact of granular sulphur fertilization in S deficient calcareous soil using blackgram (Var. VBN-8) as a test crop.Factorial randomized block design with ten treatments (T1- Absolute control;T2-Recommended dose of NPK and S (Control);T3-Soil test based NPK; T4-T3 + S as Elemental Sulphur @ 40 kg S/ha; T5-T3 + S as BSGI@ 40 kg S/ha; T6-T3 + S as BSGII@ 40 kg S/ha;T7-T3 + Vermicompost @ 4 t ha-1; T8-T4 + Vermicompost @ 4 t ha-1;T9- T5 + Vermicompost @ 4 t ha-1; T10- T6+ Vermicompost @ 4 t ha-1 ) replicated thrice and 5 pots were maintained for each replication. The results of this study revealed that there was an upward trend in all S fractions in every treatment (T1 to T10), in the following order: organic > inorganic > water soluble > exchangeable S. The pot that received vermicompost coupled with BSG II (T10) (ES@ 40 kg ha-1 and MethylobacteriumthiocyanatumVRI7-A4 as S source) was found to have the greatest S-fraction and was higher than other treatments. Therefore, using BSG II in conjunction with vermicompost is necessary to preserve the availability of S nutrients in calcareous soil and increase the solubility of nutrients through S-oxidation

Naïve Bayesian Classification Based Glioma Brain Tumor Segmentation Using Grey Level Co-occurrence Matrix Method
Brain tumors vary widely in size and form, making detection and diagnosis difficult. This study's main aim is to identify abnormal brain images., classify them from normal brain images, and then segment the tumor areas from the categorised brain images. In this study, we offer a technique based on the Nave Bayesian classification approach that can efficiently identify and segment brain tumors. Noises are identified and filtered out during the preprocessing phase of tumor identification. After preprocessing the brain image, GLCM and probabilistic properties are extracted. Naive Bayesian classifier is then used to train and label the retrieved features. When the tumors in a brain picture have been categorised, the watershed segmentation approach is used to isolate the tumors. This paper's brain pictures are from the BRATS 2015 data collection. The suggested approach has a classification rate of 99.2% for MR pictures of normal brain tissue and a rate of 97.3% for MR images of aberrant Glioma brain tissue. In this study, we provide a strategy for detecting and segmenting tumors that has a 97.54% Probability of Detection (POD), a 92.18% Probability of False Detection (POFD), a 98.17% Critical Success Index (CSI), and a 98.55% Percentage of Corrects (PC). The recommended Glioma brain tumour detection technique outperforms existing state-of-the-art approaches in POD, POFD, CSI, and PC because it can identify tumour locations in abnormal brain images

Role of Area-Level Access to Primary Care on the Geographic Variation of Cardiometabolic Risk Factor Distribution: A Multilevel Analysis of the Adult Residents in the Illawarra—Shoalhaven Region of NSW, Australia
Background: Access to primary care is important for the identification, control and management of cardiometabolic risk factors (CMRFs). This study investigated whether differences in geographic access to primary care explained area-level variation in CMRFs. Methods: Multilevel logistic regression models were used to derive the association between area-level access to primary care and seven discrete CMRFs after adjusting for individual and area-level co-variates. Two-step floating catchment area method was used to calculate the geographic access to primary care for the small areas within the study region. Results: Geographic access to primary care was inversely associated with low high density lipoprotein (OR 0.94, CI 0.91–0.96) and obesity (OR 0.91, CI 0.88–0.93), after adjusting for age, sex and area-level disadvantage. The intra-cluster correlation coefficient (ICCs) of all the fully adjusted models ranged between 0.4–1.8%, indicating low general contextual effects of the areas on CMRF distribution. The area-level variation in CMRFs explained by primary care access was ≤10.5%. Conclusion: The findings of the study support proportionate universal interventions for the prevention and control of CMRFs, rather than any area specific interventions based on their primary care access, as the contextual influence of areas on all the analysed CMRFs were found to be minimal. The findings also call for future research that includes other aspects of primary care access, such as road-network access, financial affordability and individual-level acceptance of the services in order to gain an overall picture of the area-level contributing role of primary care on CMRFs in the study region
