Design Optimization of Cam & Follower Mechanism of an Internal Combustion Engine for Improving the Engine Efficiency  [PDF]
Mahesh R. Mali, Prabhakar D. Maskar, Shravan H. Gawande, Jay S. Bagi
Modern Mechanical Engineering (MME) , 2012, DOI: 10.4236/mme.2012.23014
Abstract: The current cam and follower mechanism in four stroke internal combustion engine employs a flat follower. In this work an attempt is made to change the flat face of follower to a curved face follower, so that the required point contact can be achieved. As line contact between existing cam and follower mechanism results in high frictional losses which results in low mechanical efficiency. It is observed that the frequency of vibration in the existing and modified cam and follower mechanism remains almost same. The finite element approach is used to perform the analysis.
Focusing Anti-Corruption Efforts More Effectively: An Empirical Look at Offender Motivation—Positive, Classical, Structural and Ethical Approaches  [PDF]
Jay S. Albanese, Kristine Artello
Advances in Applied Sociology (AASoci) , 2018, DOI: 10.4236/aasoci.2018.86028
Abstract: The level of public corruption cases remains high. Interviews with 72 former investigators, prosecutors, community stakeholders and individuals with first-hand experience in corrupt activities, together with analysis of court documents, offer insight into the motivations behind the corrupt conduct in hundreds of known corruption cases. Corrupt motivations are classified into four categories: positive, classical, structural, and ethical. Empirical examples from interviews and court cases are used to show how the identified causes and correlates of corruption can be grouped and use to develop more effective anti-corruption prevention strategies. Recommendations are offered to reduce the extent of corruption by applying the principles of positive, classical, structural, and ethical explanations of corruption to reduce opportunities for corruption and improve the integrity levels of those in public service.
Selective Up-Regulation of Arginase-1 in Coronary Arteries of Diabetic Patients
Zsolt Bagi
Frontiers in Immunology , 2013, DOI: 10.3389/fimmu.2013.00293
Abstract: Coronary artery disease (CAD) remains the leading cause of death in the Western societies. Diabetes mellitus (DM) is one of the highly prevalent diseases, which remarkably accelerates the development of CAD. Experimental evidence indicates that decreased bioavailability of coronary endothelial nitric oxide (NO) contributes to the development of CAD in DM. There are recent studies showing that a selective impairment of NO synthesis occurs in coronary arteries of DM patients, which is mainly due to the limited availability of endothelial NO synthase (eNOS) precursor, l-arginine. Importantly, these studies demonstrated that DM, independent of the presence of CAD, leads to selective up-regulation of arginase-1. Arginase-1 seems to play an important role in limiting l-arginine availability in the close proximity of eNOS in vessels of DM patients. This brief review examines recent clinical studies demonstrating the pathological role of vascular arginase-1 in human diabetes. Whether arginase-1, which is crucial in the synthesis of various fundamental polyamines in the body, will represent a potent therapeutic target for prevention of DM-associated CAD is still debated.
Influence of Motor Task on Handedness
Jayasheela G.Bagi, Padmashri S.Kudachi*and Shivaprasad S.Goudar
Al Ameen Journal of Medical Sciences , 2011,
Abstract: Preferred hand used to perform various task is more skilled than the non preferred hand and use of non preferred hand to execute a task induces fatigue at a faster rate. To evaluate the possible functional asymmetries of motor tasks on dominant hand versus the non dominant hand, in the present study hand preference was assessed by using items from a standard questionnaire like Edinberg, Annet inventories and examined the manual asymmetry for both the skilled and strength/power task on handedness using different motor tests. In consistent with previous studies, the present findings point that right hand performed better than left hand in right handers [Finger Tapping; Right hand(22.0±3.2) Left hand(18.2±3.0), Grip Strength; Right hand(22.0±3.2), Left hand(18.7±5.3), p=0.050]and left hand performed better in left handers[Finger Tapping; Right hand(18.8±3.0), Left hand(18.8±3.3), Grip Strength; Right hand(20.0±8.4) Left hand(22.5±11.8), p=0.040] but the asymmetries obsevered were less for left handers compared to right handers.
A Software Architecture for Control of Value Production in Federated Systems
Jay S. Bayne
Journal of Systemics, Cybernetics and Informatics , 2003,
Abstract: Federated enterprises are defined as interactive commercial entities that produce products and consume resources through a network of open, free-market transactions. Value production in such entities is defined as the real-time computation of enterprise value propositions. These computations are increasingly taking place in a grid-connected space – a space that must provide for secure, real-time, reliable end-to-end transactions governed by formal trading protocols. We present the concept of a value production unit (VPU) as a key element of federated trading systems, and a software architecture for automation and control of federations of such VPUs.
Estimates for the number of visible galaxy-spanning civilizations and the cosmological expansion of life
S. Jay Olson
Physics , 2015,
Abstract: If advanced civilizations appear in the universe with a desire to expand, the entire universe can become saturated with life on a short timescale, even if such expanders appear but rarely. Our presence in an untouched Milky Way thus constrains the appearance rate of galaxy-spanning Kardashev type III (K3) civilizations, if it is assumed that some fraction of K3 civilizations will continue their expansion at intergalactic distances. We use this constraint to estimate the appearance rate of K3 civilizations for 81 cosmological scenarios by specifying the extent to which humanity could be a statistical outlier. We find that in nearly all plausible scenarios, the distance to the nearest visible K3 is cosmological. In searches where the observable range is limited, we also find that the most likely detections tend to be expanding civilizations who have entered the observable range from farther away. An observation of K3 clusters is thus more likely than isolated K3 galaxies.
Continuous Differentiability of Renormalized Intersection Local Times in R^{1}
Jay S. Rosen
Mathematics , 2009, DOI: 10.1214/09-AIHP338
Abstract: We study $\gamma_{k}(x_2,...,x_k;t)$, the k-fold renormalized self-intersection local time for Brownian motion in $R^1$. Our main result says that $\gamma_{k}(x_2,...,x_k;t)$ is continuously differentiable in the spatial variables, with probability 1.
Quality Enhancement of Manufacturing Process by Simulation Technique: A Case Study
Prof D.A. Pathak,Prof J.S.Bagi
International Journal of Engineering Science and Technology , 2012,
Abstract: Industries need quality improvement of manufacturing process as it helps to decrease the operation cost, to improve product quality, etc. Quality improvement can be established by controlling quality of raw material. A technique that can be used to do this task is simulation. The paper mainly focuses upon one of the case studiesof the quality improvement of one of the printing machine product in ABC company with simulation technique. The simulation software used is the FLEXSIM 5 which is developed by Canyon Park Technology Center,Orem-Utah, USA. The software can be freely downloaded from the internet with negligible cost. Simulation had a lot influence on the manufacturing process because inventing more powerful tools will make the user to work easily and also to implement any kind of models. Operating within large complex systems also possible by usingdistributed technology and which also addressed as web based simulation.

International Journal of Engineering Science and Technology , 2011,
Abstract: The design and implementation of an organization's quality management system is influenced by varying needs, particular objectives, the products provided, the processes employed and the size and structure of the organization. ISO 9001:2008 specifies requirements for a quality management system where an organization needs to demonstrate its ability to consistently provide product that meets customer requirements, and aims to enhance customer satisfaction through the effective application of the system, including processes for continualimprovement of the system. This paper focused on the methods for assessment of quality objectives at ABC industry. This is useful for them not just for improving their supply chain performance but for improving their outsourcing strategies and approach. The quality level is also increased from 3.83σ to 4.15σ. The organizationcontinually improves the effectiveness of the Quality Management System through the use of quality policy,quality objectives, analysis of data, corrective and preventive action etc.
“Performance and Reliability Improvement in the Design and Manufacture of Water Cooled Submersible Pump and Motor by Solid Modeling and CFD”
Prof.P.B. Kadam,Prof. J.S. Bagi
International Journal of Engineering Science and Technology , 2011,
Abstract: Submersible Pumps have lots of problems regarding durability of bearing bush getting worn out very fast after its commissioning, winding getting damaged burnt out quickly, the stacked laminations in the motor were getting twisted or entangle so badly that the motor had to be scraped i.e. no repair possible at all. Total product failure in just 3 to 4 months. This paper describes the method to determine the optimum dimensions of the bearing bush made ofspecified material and withstand a bearing pressure of bearing bush. The results obtained are verified by using CFD analysis which is improved in order to meet and anticipate customers increasing demand for performance and reliability.
