METHODOLOGY OF TEACHING MATHEMATICS IN RELATIONSHIP WITH OTHER SUBJECTS
No full textThis article discusses different perspectives, methods, and contributors to the teaching of mathematics, interesting topics, and the interrelationships of mathematics with other disciplines, as well as the attitudes of scholars who have contributed to it
MODIFICATION AND CORRECTIVE ACTION OF OIL GROOVE FOR HIGH PERFORMANCE BEARINGS
No full textThe article deals with the failure of bearings due to oil starvation due to absence of sufficient oil film between the bearing and the journal permits metal-to-metal contact this resulting wiping action causes premature bearing fatigue and High loads applied to the bearings result in a reduction of minimum oil film thickness so to prevent such failure specific load applied to the grooved bearing may be lowered by means of a reduction in groove width by modification in groove design
PROBLEMS AND SOLUTIONS OF ONLINE EDUCATION IN TERTIARY INSTITUTIONS
No full textThis article provides an overview of the shortcomings in online education in today's pandemic conditions and the possible solutions to them. Indeed today, the quality of online education is at a very above level and not everyone is aware of it. If this article is little, foreign experiments have come to eliminate these shortcomings
SIMULATION OF DC NETWORK THEORMS USING ADVANCED SIMULATION SOFTWARE LT SPICE AND COMPARING THE BOTH RESULTS CALCULATED MANUALLY AND BY SOFTWARE.
No full textIn this paper we compare the results of standard d.c theorms application on different circuits and compare their results with simulation solution using iteration method . The simulated results shows the result values calculated by these theorems and also as calculated manually and results are compared. So this research paper compares the results calculated both ways and deviations are observed
A REVIEW ON LANE DETECTION AND TRACKING TECHNIQUES
No full textMost of the people die every year in road crashes dueto driver’sinattention and not following the traffic rules.The Lane detection systems are useful to avoid the accidents and safety is the main purpose of the system.The main goal of these systems isto detect the lanestripesand to warn the driver in case of the vehicle tend to depart from the lane. Many intelligent vehicles transport systems have the lane detection system as an important element while driving. Therefore, Lane detection and tracking is the challenging task in computer vision. In thispaper, the different vision based lane detection techniquesand algorithms are discussed. The performance of the different lane detection technique is also compared and studied
TECHNOLOGY ASSESSMENT OF DUMONIA
No full textThe following report aims to highlight how Dumnonia company will implement the k-anonymity model for maintaining and preserving the privacy of big data. This company is serving citizens in New Zealand and Australia with different types of insurance services such as vehicle insurance, death insurance, and travel insurance. As the organization is dealing with the medical data of citizens so it is important to implement effective security controls for maintaining data confidentiality and privacy. In order to deal and manage with massive amount of medical and insurance data, the business executives of company have decided to opt bigdata. The traditional data management models are unable to process a huge volume of big data because this data has been gathered from unstructured and unstructured data sources. Hence, the organization needs to implement effective security management tools that would promote preservation of data confidentiality and privacy along with high system performance
MODELING, DESIGN, DEVELOPMENT, TESTING & ANALYSIS OF DUAL WORM SELF LOCKING SYSTEM FOR IMPROVED TRANSMISSION EFFICIENCY & DECELERATION LOCKING PROPERTY
No full textIn many cases wherever material handling equipment gear drives are used because of their efficient transmission of power. But disadvantage of this system are whenever power shut down occurs or may be mechanical failure occurs are input side of the system. If this situation occurs, guarantee of rotation of the shaft cannot be predicted. It can move in both the direction, either it can continue moving in same direction because of inertia or it may move in opposite direction because of gravity of the load. Moving in the reverse direction is also called as back driving [1]. To prevent back driving self locking gears can be provided, which doesn’t move in opposite direction
A KINETIC STUDY ON MALENISATION OF SOYBEAN OIL
No full textMalenisation of soybean oil with maleic anhydride was investigated.The effect of variations in weight percent ratio of reactants on rate of reaction has been studied. Sodium bisulphate and sodium bisulphite are used as catalyst for the malenisation of soybean oil. The reaction kinetics is estimated for soybean oil – maleic anhydride ranging from 75:25 to 90:10. The optimum conditions are found to be 85:15 soybean oil:maleic anhydride weight percent ratio and 2 % catalyst at 2300C for 330 minutes with conversion of 82.48% and yield of 95%
Three-phase-to-ground fault and its impact on voltage magnitude
No full textAccording to growth of electricity demand and the increased number of non-linear loads in power grids, providing a high quality electrical power should be considered. In this paper voltage sag of the power quality issue is studied. Voltage sag due to power system fault,three-phase-to-ground is created in distribution line model, their effect on the voltage magnitude variation by varying fault resistance for each phase are examined. A simple and practical method is proposed for voltage sag detection, by calculating RMS voltage over a window for particular time period. The case study contains a single-machine including distribution line, which is simulated in MATLAB/Simulink environment.
POWER QUALITY IMPROVEMENT FOR ENERGY SAVING
No full textIn an industrial environment more number of motor load are operated through power electronic control device. Asa characteristicof power electronic controller,the non linear in the load will detoriated power quality in the system which may lead to increase in power losses. With the development of power electronic controller using multilevel switching device it is possible to improve the power quality.This paper present analysis of improvement in the power supply and power quality compensation feeding to a nonlinear load in industrial environment. Exhaustive simulation research ispresented toverify the performance analysis
