Environment Friendly Voltage Up-gradation Model for Distribution Power Systems

The main aim of this research work is to analyze and develop voltage up gradation procedure model for effective & economic power distribution in urban and suburban area. Voltage up gradation from 6.6KV to 11KV of the distribution power system network has been considered for the proposed research work. Electric power consumption has been increasing uninterruptedly, being this increase specially accelerated in the last few years. Nowadays electric lines are saturated; they are reaching critical values of ampere capacity and sag. Therefore, building new lines has been necessary to provide the ever increasing consumption.  The difficulty to find new corridors to construct new distribution lines, underground cables is increasing in cities, industrial areas and in many cases it is simply impossible. The construction of new electric lines is increasing difficulty, thus there is a need to look at alternatives that increases the power transfer capacity. Voltage up gradation of the existing electric cables/lines of the distribution system is the most viable solution and it stresses on the savings of power due to a reduction in system losses when the voltage is high. The proposed research work is to develop and analyze voltage up gradation procedures and protocols for converting 6.6KV network into 11KV network in a distributed system. It also takes into account the expenses incurred in the process and the various other important constraints

Literature Review on Vague Set Theory in Different Domains

Problem of decision making is a crucial task in every business. This decision making job is found very difficult when it is depends on the imprecise and vague environment, which is frequent in recent years. Vague sets are an extension of Fuzzy sets. In the fuzzy sets, each object is assigned a single value in the interval [0,1] reflecting its grade of membership. This single value does not allow a separation of evidence for membership and evidence against membership. Gau et al. proposed the notion of vague sets, where each object is characterized by two different membership functions: a true membership function and a false membership function. This kind of reasoning is also called interval membership, as opposed to point membership in the context of fuzzy sets. In this paper, reviews the related works on the decision making by using vague sets in different fields

Challenges in Globalisation of Global Software Development: A Conceptual Study of Co-locating Key Roles and its Impact on Product Life Cycle

This study characterises the results of published scientific research in the field of Global Software Product Development (GSD). Based on the analysis of about 22 scholarly articles published between 2001 and 2014, it is observed that in spite of issues and challenges faced in its implementation, GSD is a business necessity. To ensure more successful realisation of the benefits of GSD, co-locating some of the key-roles at global locations along with software development could be exercised. This could have a positive impact on the software product life cycle. This relationship needs to be validated by further research backed with empirical data.     &nbsp

Indian Financial Systems and Stockmarkets During COVID 19- Shape off Post Covid Through AI and Other Digital Tools

Introduction: Apart from the loss of precious lives, COVID-19 pandemic caused setbacks to all the developmental works, progress of the economy of all countries with serious repercussions on financial systems and stock markets. Most economies, including Indian stock markets since recovered from the shock, showing robustness due to stringent regulatory framework, started rebuilding, from the vertical fall. India as a nation had sufficient leeway to respond to the crisis and market instability, due to its inner strength. Aim: This is a theoretical study of the reaction of stock markets, also of expansionary monetary policies during pandemic, the resurgence of financial system and recovery of Indian stock markets, with extreme adoption of Digital tools like AI for Algo trading . Method: Secondary research methods have been adopted, for analyzing conceptual approaches of regulatory frameworks of the Securities market, Central bank, amid volatility, to draw conclusions. The stock market data (NSE) is subjected to VaR test. Findings: The Study finds that country has responded quickly to the outbreak of the crisis by easing capital and liquidity requirements or at least refraining from the previously planned tightening. At the same time, the authors noticed that loan-based measures and minimum reserve requirements were rarely relaxed and risk weights were not changed at all. Digital tools like Algo trading, AI based advisory gained prominence Conclusion: The impact of novel coronavirus (COVID-19) pandemic on financial system and the stock markets in India, is significant. But Monetary policy, liquidity operations and aid packages that were offered by the Government have minimized the impact to a large extent and brought the financial systems back onto the rail. Key Words: Corona Virus, Financial Markets, Stock market, Algo trade

Two- & Three-character solutions to MLDEs and Ramanujan-Eisenstein Identities for Fricke Groups

In this work we extend the study of arXiv:2210.07186 by investigating two- and three-character MLDEs for Fricke groups at prime levels. We have constructed these higher-character MLDEs by using a $\mathit{novel}$ Serre-Ramanujan type derivative operator which maps $k$-forms to $(k+2)$-forms in $\Gamma^{+}_0(p)$. We found that this $\mathit{novel}$ derivative construction enabled us to write down a general prescription for obtaining $\mathit{Ramanujan-Eisenstein}$ identities for these groups. We discovered several $\mathit{novel}$ single-, two-, and three-character admissible solutions for Fricke groups at levels $2$ and $3$ after solving the MLDEs among which we have realized some in terms of Mckay-Thompson series and others in terms of modular forms of the corresponding Hecke groups. Among these solutions, we have identified interesting non-trivial bilinear identities. Furthermore, we could construct $\mathit{putative}$ partition functions for these theories based on these bilinear pairings, which could have a range of lattice interpretations. We also present and discuss modular re-parameterization of MLDE and their solutions for Fricke groups of prime levels.Comment: 94 pages + 14 pages (appendices and references); 3 figures; 13 table

Estimation of MRR Using U-Shape Electrode in Electrochemical Machining

Non-traditional machining has grown out of the need to machine exotic engineering metallic materials, composite materials and high tech ceramics having good mechanical properties and thermal characteristics as well as sufficient electrical conductivity. Electrochemical Machining developed in late 1950’s has been accepted worldwide as a standard process in manufacturing and is capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, composites, super alloys, ceramics, carbides, heat resistant steels etc. being widely used in die and mold making industries, aerospace, aeronautics and nuclear industries. The principle of anodic dissolution of metal theory is the most accepted mathematical model for evaluating material removal from electrodes during electrochemical process. If two suitable metal poles are placed in a conducting electrolyte and a direct current passed through them, the metal on the positive pole get depleted and its material is deposited on the negative pole. Keeping this in view, the present work has been undertaken to finding the material removal rate by electrochemical dissolution of an anodically polarized work piece with a U-shaped tubular copper electrode. In the experiment, AISI D2 steel is used as specimen. Experiments were carried out to study the influence of machining parameters such as feed rate, applied voltage, conductivity and flow rate on the over cuts in length, width and height of the specified cavity

Adult chordoid meningioma: a case report

Chordoid meningioma is a rare tumour accounting for less than 0.5% of all meningiomas. It is a WHO grade II tumour with an aggressive behavior. It is a rare variant characterized by cords or trabeculae of eosinophilic or vacuolated cells set in an abundant mucoid matrix. It can be associated with systemic or hematologic manifestations like Castleman disease. The tumor has a propensity for aggressive behavior and increased likelihood of recurrence We report a case of an adult patient with chordoid meningioma who presented with headache and seizures and did not have any hematological/ systemic manifestations. She underwent total excision of the lesion and is doing well

Comparison of Modified Fluorescent Method and Conventional Ziehl Neelsen Method in The Detection of Acid Fast Bacilli in Lymph Node Aspirates.

Pulmonary Tuberculosis (TB) Is A Contagious Bacterial Infection That Involves The Lungs, But May Spread To Other Organs. The Great Pioneer Of Bacteriology, Robert Koch, Discovered A Bacterium Which He Called Bacillus Tuberculosis And Is Now Known As Mycobacterium Tuberculosis, Is The Etiological Agent Of Tuberculosis[1]. Tuberculosis Continues To Be A Major Health Problem In Developing Countries Due To Poor Sanitation, Overcrowding And Lack Of Knowledge About The Disease. AIDS Patients Show Coinfection With Mycobacterium Tuberculosis. More Than 50% Of Tuberculosis Cases Are From Asia And Africa Alone. It Has Been Estimated That One Patient Die Every Minute Due To MTB In India. Symptoms Of Pulmonary TB Include Cough , Coughing Up Blood(Hemoptysis), Excessive Sweating Especially At Nights, Fatigue, Evening Rise Of Temperature, Unexplained Weight Loss. Other Symptoms That May Occur With This Disease Are Dyspnea, Chest Pain, Wheezing., Clubbing Of The Fingers Or Toes (In People With Advanced Disease), Enlarged Or Tender Lymph Nodes In The Neck Or Other Areas, Pleural Effusion, Unusual Breath Sounds (Crackles)[2,3]. TB Is A Preventable And Potentially Curable Disease Provided It Is Detected Earlier In The Course Of The Disease. Microscopy Is The Most Common Case Detection Test In Use. Microscopy Is Inexpensive, Relatively Rapid To Perform, And, In Countries Where Tuberculosis Is Endemic, Is Highly Specific. The Average Sensitivity Of Sputum Microscopy For Pulmonary Tuberculosis In Immunocompetent Individuals Is Less Than 60% Compared With Culture, Even In Research Settings[5]. Microscopy Can Also Be Done In Other Pathological Materials Like Lymph Node Aspirates And Body Fluids Including CSF. The Diagnostic Value Of FNAC Of Lymphnodes In Tuberculous Lymphadenitis Has Been Emphasized By Several Workers[6,7,8]. FNAC Examination Is Simple, And A Relatively Painless And Less Cumbersome Procedure Introduced First By Martin[9], Can Be Adopted In Lieu Of Biopsy. This Can Be Carried Out As An O.P.Procedure And Preparation Of The Smears Can Be Carried Out In The Laboratories Even At The Peripheral Hospitals. This Will Serve As An Effective Adjuvant In Arriving At An Appropriate Diagnosis. Identification Of AFB In Lymph Node Aspirates By The Routine H&E Stain Is Difficult. We Give A Diagnosis Of Granulomatous Lesion Based On The Presence Of Epitheloid Cell,Giant Cells And Caseous Necrosis.As The Etiology Of Granulomatous Lesions Are Varied We Need To Arrive At A Definitive Diagnosis For The Cause Of The Granulomatous Lesions MTB Is The Commonest Cause Of Granulomatous Lesion In Our Country.In Order To Give A Definitive Cytological Report That The Cause Of Granulomatous Lesion Is Due To MTB,We Have To Employ Special Stains Like Ziehl Neelsen .Ziehl Neelsen Method Is The Current Gold Standard Test Employed For The Identification Of AFB On FNAC Smears. But The Sensitivity Is Low .MTB Culture Though Sensitive And Specific Takes A Longer Time For The Growth Of The Organism. The Tests Based On PCR Have Shown Promise For The Detection Of Mycobacteria In Clinical Samples[15]. However, Several Different PCR Systems That Have Been Described For The Diagnosis Of Tuberculosis Have Produced Widely Differing Results With Regard To The Sensitivity Of The Assay With Different Types Of Clinical Samples .PCR Although A Sensitive Test Detects Both Viable And Non Viable Bacilli[16]. Peripheral Blood Appears To Be The Clinical Material Of Choice For PCR, Especially In Cases Of Disseminated And Extrapulmonary Forms Of The Disease[17]. Hence We Need A Test Which Should Be Sensitve, Rapid, Easy To Perform And Cost Effective As Well. Auramine O Has Been Used In Fluorescence Acid-Fast Microscopy Since It Was First Introduced By Hageman In 1938 And Reported By Richards Et Al[11]. This Method Is Said To Be More Sensitve Than The Ziehl Neelsen Method And Can Be Performed On Lymph Node Aspirates As Well. In This Study The Sensitivity, Specificity, Efficacy And Other Advantages Of Using AO Stain Over The Conventional Gold Standard Ziehl Neelson Stain In Granulomatous Lesions Of Lymph Node Are Compared And The Results Analysed
