An attempt to improve the poor performance characteristics of coconut oil for industrial lubricants
Suresh Babu Valeru,Y. Srinivas,K. N. S. Suman 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.4
Coconut oil is used as the base fluid for metal cutting applications because of its high natural properties compared to other vegetable oils. The major hindrances to extensive utilization of coconut oil compared to mineral oils for various metal cutting operations are its high pour point, low oxidation and thermal stability therefore further improvement in these aspects is much needed. In this work, a systematic approach to improve the cold flow behavior, oxidation and thermal stability of the coconut oil by the combination of chemical additive i.e 2,6 Di-tetra butyl phenol and diluents such as Poly alpha olefin4(PAO4), Poly (Ethylene co-vinyl acetate) (PPD) has been carried out. Based on the obtained results an improvement of cold flow behavior (least pour point) was observed with the addition of PAO4 and PPD with varying weight percentage combinations. Apart from this addition of 2, 6 Di-tetra butyl phenol as anti-oxidant (AO) in various weight percentage has led to an improvement of oxidation and thermal stability to the primarily modified coconut oil.
A New Sort of Study upon Devices Life Span Advancement Techniques with Wireless Sensor Communities

In the previous years, Wireless Sensor Networks (WSNs) have increased expanding consideration from both the clients and scientists. It is utilized as a part of different fields which incorporate ecological, social insurance, military and other business applications. Sensor hubs are battery fueled so vitality imperatives on hubs are extremely strict. At the point when battery gets released, sensor hub will get detached from remaining system. This outcomes in connection disappointment and information misfortune. In a few applications battery substitution is likewise impractical. Consequently, vitality proficient strategies ought to be outlined which will upgrade lifetime of system and precise information exchange. In this paper, diverse wellsprings of vitality dissemination are recorded trailed by vitality effective systems to improve lifetime of the system.
A Comparative Analysis on Performance of Wireless Sensor Networks Routing Protocols
KRISHNA, KONDA. HARI,NAGPAL, TAPSI,BABU, Y. SURESH International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.7
The common goals of designing a routing algorithm are not only to reduce control packet overhead, maximize throughput and minimize the end-to-end delay, but also take into consideration the energy consumption. Scalability is an important factor in designing an efficient routing protocol for wireless sensor networks (WSN's). Three metrics (power consumption, time of transmission and packet loss rate) are used in order to compare three routing protocols which are AODV, DSDV and LEACH.
Dynamism Competent LEACH Replication Deliberate for Wireless Sensor Network
KONDA HARI KRISHNA,TAPSI NAGPAL,Y. SURESH BABU International Journal of Computer ScienceNetwork S 2023 International journal of computer science and netw Vol.23 No.5
Remote sensor systems are utilized in a few applications, including military, restorative, ecological and family unit. In every one of these applications, vitality use is the deciding component in the execution of wireless sensor systems. Thusly, strategies for information steering and exchanging to the base station are critical in light of the fact that the sensor hubs keep running on battery control and the vitality accessible for sensors is constrained. There are two explanations for the various leveled directing Low Energy Adaptive Clustering Hierarchy convention be in investigated. One, the sensor systems are thick and a considerable measure of excess is engaged with correspondence. Second, with a specific end goal to build the versatility of the sensor arrange remembering the security parts of correspondence. In this exploration paper usage of LEACH steering convention utilizing NS2 test system lastly upgraded vitality productive EE-LEACH directing convention guarantees that the chose cluster heads will be consistently conveyed over the system with a specific end goal to enhance the execution of the LEACH convention. EE-LEACH enhances vitality utilization by around 43%.
