Authors: Dubey Kaushalendra K. , Mishra R. S. , Sinha Gopal P.
Published: January 2023

This paper describes the idea of the development of a solar thermal energy driven pump for lifting of ground water for irrigation as well as for meeting urban supply system. The principles are equally applicable for lifting any liquid, the head being dependent on density of the liquid. This has the potential of saving over 93billion kWh of electrical energy and 3.3 billion litres of diesel (fossil fuel) per year, for India. The invention has been patented. The most attractive feature of the pump is the absence of any moving part, which makes it almost maintenance-free. Syphon action created by water vapour picked-up from the source, lifts the water from the reservoir through the delivery head. This is being demonstrated for the first time. The efficiency of the entire system is also high on account of no moving parts. Solar thermal energy is used to create a pressure higher than the atmospheric pressure, over the surface of liquid to be pumped to height H. The pressure lifts the liquid through a tube dipped below its surface and delivers to head H, determined by additional pressure created through thermal energy and the mass-density of the liquid.

Authors: Dwivedi Shashi Prakash , Sharma Satpal , Mishra Raghvendra Kumar
Published: January 2023

In numerous applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing the fluid flow in the mushy zone by mechanical stirring is one of the means to suppress this dendritic. Several manufacturing techniques have been invented for fabrication of metal matrix composites. One of the popular ways of generating non-dendritic microstructure is to stir the liquid metal during solidification using an electromagnetic force field. However, the main problem faced in the electro magnetic stir (EMS) casting is the selection of optimum combination of input variables for achieving the required physical, mechanical and tribological properties of composites. Therefore, in the present work an attempt has been made to review electromagnetic stir casting and its process parameters for the fabrication and refined the grain structure of metal matrix composites that possesses exceptionally good mechanical properties as well as tribological properties.

Authors: Singh Sachin
Published: January 2023

Firewall is a most crucial element to implement security policies in a network and also crucial to success of network rather say to success of an organization. Despite of its important in any network it has many problems and one of them is increasing number of rules in firewall’s rule set. Since in today’s environment, enterprises looking to provide strongest security to their users and also want to secure their data at maximum level and hence they have increased rules in firewall’s rule set. However increasing number of rules in firewall rule set is not an efficient way to provide maximum security. And this study shows that how can the use of minimum number of rules in firewall rule set to implement optimum security is possible. It has also proved that this problem of minimizing maximum firewall rule set in network is NP complete. One point is noteworthy to mention here that in today’s time as enterprises are moving towards cloud technology the complexity at data center is increased and it is being difficult to implement security in clouds. So by having highly optimized firewalls, it is possible that they can be used to provide security in clouds.

Authors: Mahalakshmi N. , Saranya S. R.
Published: January 2023

Multi-object tracking is still a challenging task in computer vision. A robust approach is proposed to realize multi-object tracking using camera networks. Detection algorithms are utilized to detect object regions with confidence scores for initialization of individual particle filters. Since data association is the key issue in Tracking-by-Detection mechanism, an efficient HOG algorithm and SVM classifier algorithm are used for tracking multiple objects. Furthermore, tracking in single cameras is realized by a greedy matching method. Afterwards, 3D geometry positions are obtained from the rectangular relationship between objects. Corresponding objects are tracked in cameras to take the advantages of camera based tracking. The proposed algorithm performs online and does not need any information about the scene, any restrictions of enter-and-exit zones, no assumption of areas where objects are moving on and can be extended to any class of object tracking. Experimental results show the benefits of using camera by the higher accuracy and detect the objects.

Authors: Kumar Kapil , Mishra Sumit Kumar , Kumar Sumit
Published: January 2023

In the present study, an attempt has been made to investigate the effect of machining parameters (cutting speed, feed rate, depth of cut and tool nose radius) on material removal rate and surface roughness in finish hard turning of H13 tool steel using carbide tool. The machining experiments were conducted based on response surface methodology (RSM) using face centered central composite design. A comprehensive analysis of variance (ANOVA) was used to fully identify the most influential parameters, and the adequacy of both fitted second order regression models were checked. 3D response surfaces and 2D contour plots were analyzed to completely observe the impact of combinatory different important interactive factors on the machinability behaviour under different turning conditions. The MRR and SR increase by increasing the cutting speed, feed rate and depth of cut. The depth of cut and feed rate are the most influential factors for increasing the MRR and SR respectively. Mathematical models for MRR and SR were developed by using Design Expert-9 software. Finally, a multi-objective optimization technique based on the use of desirability function (DF) technique was then applied to find optimal combinations of input machining parameters capable of producing the highest possible amount of MRR and lowest amounts of SR within process domain. The obtained predicted optimal results were then verified experimentally to compute confirmation errors. The values of relative validation errors, all being found to be quite satisfactory, 5.29% for MRR and 8.1% for SR, proves the efficacy and reliability of suggested approach.

Проблеми формування здоров'язберігаючої компетентності студентів: теоретичний аспект
Authors: Лущинський Юрій , Штомпель Юлія
Published: January 2023

У статті розкрито шляхи формування здоров’язбережувальної компетентності студентів. Увагу зосереджено на особливостях фізичного виховання молоді як головного чинника формування зазначеної компетентності. Визначено мету фізичного виховання як зміцнення здоров’я, сприяння гармонійному розвитку особистості, підготовка молоді до праці й захисту України, а відтак – формування здоров’язбережувальної компетентності не лише учнів закладів загальної середньої освіти, а й студентів закладів вищої освіти.

Проаналізовано особливості забезпечення фізичного виховання  студентів у закладах освіти та сім’ї. З’ясовано, що система фізичного виховання здобувачів освіти спрямована на розв’язання оздоровчих, освітніх, виховних завдань. Зокрема, оздоровчий напрям передбачає фізичний розвиток студентів, покращення функціональних можливостей організму, підвищення його опірності до несприятливих факторів внутрішнього та зовнішнього середовища, надаючи домінантну роль здоров’ю в усіх формах роботи зі студентами.

Визначено роль сім’ї у формуванні здоров’язбережувальної компетентності, вихованні здорової, фізично розвиненої особистості, підготовці її до суспільно-корисної діяльності, оскільки вона як специфічна педагогічна система виконує й виховну функцію, що полягає в передачі молодому поколінню дорослими членами сім’ї соціального досвіду, забезпеченні їхнього входження в систему суспільних відносин.

Published: January 2023

У статті обґрунтовано значення естетичного виховання у процесі професійної підготовки майбутніх фармацевтів. На основі аналізу наукової літератури та власних досліджень визначено поняття «естетичне виховання» як цілеспрямований процес взаємодії педагога та студента в процесі освітньо-виховної діяльності, який передбачає сформованість: естетичних смаків та почуттів; вміння бачити й оцінювати красу в природі, мистецтві, літературі; потреби долучатися до різних галузей мистецтва, творчо перетворювати дійсність особисто; здатність бачити красу в праці, зокрема, у професії, отримувати насолоду від процесу та результату діяльності; вміння оцінювати красу і благородство взаємин між людьми; потреби вносити прекрасне в навколишній світ, зберігати прекрасне. Окреслено мету та завдання естетичного виховання в освітньо-виховному процесі закладу фахової передвищої освіти, а також взаємозв’язок з іншими напрямами виховної діяльності. Описано особливості першого етапу формування естетичної культури особистості – естетичне сприйняття; виокремлено чинники, які негативно впливають на процес його формування. Наведено конкретні приклади реалізації естетичного виховання за допомогою інноваційних і традиційних форм, методів, засобів виховної роботи. Наголошено на важливості актуалізації естетичного виховання на сучасному етапі модернізації освіти як втілення принципу гуманізації професійної освіти, що спонукатиме до посилення морального, духовного, творчого розвитку особистості майбутнього фармацевта.
DESIGN OF TRAFFIC ACCIDENT PREDICTION MODEL IN TOLL ROAD USING A DECISION TREE ALGORITHM

Published: January 2023

A toll road is a road that the users are obligated to pay, which is held to improve efficient transportation services. Although toll roads have relatively more ideal conditions than highway roads, many traffic accidents still occur on the road. Toll road managers collect operational data on toll roads, including daily traffic, weather, and accident data. One of the solutions to increase the level of toll road safety is to design an accident prediction model through data mining. In this paper, the prediction model was made using attributes according to the framework consisting of day, type of road surface, weather conditions, road surface conditions, time of occurrence, driver sex, and type of vehicle. The prediction model was built to predict certain areas' probability and severity of accidents. The prediction model is built using the decision tree algorithm. The results show that the attributes used can predict the severity of accidents with 39.73% accuracy. The most vulnerable area is in section B on 9 to 10 km, with a total number of accidents of 13.17% of total accidents.
