Abstract: |
In this study, bending strength and impact value of palm fiber grain infill in polyester is measured, using variation of specific grain size 80,180, 280 and powder composition or volume fraction 10%, 20% and 30 %..Bending strength of the composition material decrease due to palm fiber powder mesh size decreament and volume fraction increment with maksimum bending strength is 92 N/mm2 at grain mesh size 80 and volume fraction 10%. Impact value reach maksimum 0.002683 J/mm2 with mesh size 180 dan volume fraction 30%. Palm grain size affects bending strength and impact value significantly. Water absorption value of powder composition and powder size mesh also measured. Water absorption increase due to powder composition rate increament also mesh size increament and at rest after 192 hours of immersion. |

Abstract: |
This project is responsible for developing and executing advanced advancements in inserted frameworks for energy-saving road lighting. Currently, we employ a manual structure, in which the road lights are turned on the night before and turned off the next morning. Regardless, the genuine planning for these traffic lights would be switched to ON when there would be complete darkness. Power dissipation occurred to a certain extent here. As a result, we are wasting energy. Furthermore, the suggested lighting architecture is devoid of any physical operation. This new framework provides a solution for preserving vitality. This is performed by detecting and moving approaching a vehicle with the use of a PIR transmitter and an infrared receiver. Simultaneous sensor developmental detection transmits information to an ESP32 Cam, which simultaneously turns on the light. When a vehicle or a deterrent exits the Light extort turns OFF when a sense is made by a sensor for each question in a meantime the status; (Turn ON / Turn OFF) of street light of the road got to from anywhere and buttoned up web The venture was realized; a cleverly included framework that supervises roadway lighting in light of the identification of trucks, buses, vehicles, and other impediments. |

Abstract: |
The goal of this project is to use the Raspberry Pi to create a facial recognition system for car access control. For future generation automobiles, this initiative adds sophisticated security measures. For the envisioned advanced system, the Raspberry Pi will serve as a command module. Only authorized and registered people are allowed to operate the car due to the robust security system. Generally a key is used to unlock and start a vehicle. But in this project demonstrates the unlocking and starting a vehicle using facial recognition. Which not only is efficient but also will help reduce car thefts. Here, the face detection system takes multiple photos of the person and stores this data into its database. While scanning, when the face is detected by the camera the system compares the given face with the images in the database and authorizes the person, if the person is already registered then it starts the vehicle or else identifies the person as invalid user and the buzzer goes on and access is denied and the motor doesn’t start. To clear data the user need to use the clear option to clear entire data. |

Abstract: |
In this paper, we investigate the mean delay of packets with different priorities in cognitive radionetworks (CRN) using queueing models in studying the performance of the secondary users underthe pre-emptive resume and pre-emptive repeat priority scheduling systems under severaloperating conditions. It is found that the pre-emptive resume priority gives better performanceunder all the conditions. Specifically, we consider four scenarios for CRN. Results revealed thataverage delay of SUs in the queue and SU packet loss probability is worst when the arrival rate ofPU is greater than SUs, and a better performance when the arrival rate of both users are the same. Furthermore, the model gives the best performance when the arrival rate of SUs is greater than PUs. |
