Abstract: In this study, we investigated the cause of the contact failure phenomenon of the oil temperature sensor whose signal error occurred intermittently during vehicle driving. The electrical contact failed sensor was disassembled and observed the contact surfaces with a scanning electron microscope (SEM). In the case of the present oil temperature sensor, the difference in thermal expansion coefficient of the male-female terminal and the vibration during driving cause fretting corrosion at the contact area. Fretting corrosion causes the signal error intermittently. It is judged that the lead wire composed of the flexible thin plate is structurally vulnerable to vibrations during driving, which further causes fretting of the contact point. Therefore, it is necessary to design an additional structural supplement to fix the flexible terminal of the sensor system.

Keywords: Oil Temperature Sensor, Automotive Transmission, scanning electron microscope (SEM).

Abstract: The construct of cloud computing has not only remolded the field of distributed system but also essentially changed how business potentiality expand today. In late furtherance, cloud computing applications are allow for as servicing to end- users. The applications services hosted under Cloud computing role model have composite provisioning, configuration, and deployment essentials. How to utilize Cloud computing resources expeditiously and attain the uttermost winnings and efficient usage of resources is one of the Cloud computing service supplier ultimate goals. Repetitious valuation of the performance of Cloud provisioning policies, application workload framework, and resources performance frameworks in active system are difficult to accomplish and instead a time consuming and costly approach. To defeat this challenge, cloud analyst simulator based on CloudSim has been projected which enables the modeling and simulation in cloud atmosphere. The aim of this paper is to prove that the choice of VM Scheduling Policy in Cloud computing frame work importantly improves the application performance under resource and service demand fluctuation. Hence We will discuss different Virtual. Machine (VM) Scheduling Policies implemented and their performance analysis in virtual environment of  cloud computing in order to achieve better Quality of Service(QoS). 

Keywords: CloudSim, Cloud Analyst. Scheduling Policies and virtual Machine.

Abstract: Voltage flicker is an essential part of power quality in view of inescapability in mechanical frameworks. Be that as it may, flicker mitigation is a standout amongst the most difficult power quality issues from the mitigation planned in view of its irregularity. This paper presents an enhancement for the DSTATCOM control procedure to diminish the instantaneous flicker level (IFL) with the goal that it is lower than detectable level perceived by IEEE and IEC gauges. In addition, it is exhibited that the proposed control calculation is compelling and straightforward, and its execution is confirmed by digital simulation results.

Abstract: Speaker Recognition System is increasingly being deployed as a more natural means for recognition of people. Speaker Recognition (SR) is the process of automatically recognizing the person speaking on the basis of the information obtained from the speech features. In today world scenario, speaker recognition system is very popular in voice verification for identity and access control to services. Speaker identification and verification are basic part of speaker recognition system. Basically it is a process of automatically recognizing the identity of speaker on the basis of individual information extracted from speech signals. Our main purpose is to reduce error in the system and increase the efficiency. In this report, it is done with the help of different feature extraction algorithm. We have introduced a new approach for speaker recognition. This new system firstly frames the speech signals and then these signals are compressed using DWT for noise reduction and better sampling frequency. Furthermore, features of compressed signals are extracted with the help of Discrete Wavelet transform (DWT), Non-Linear Energy operator (NEO) based DWT, and Irregular Discrete Wavelet Packet transform (IRR DPWT). The distance metrics incorporated are Delta Bayesian Information criteria (delta BIC). At the end results are evaluated with Detection Error Tradeoff (DET) curve and Receiver Operator Characteristics (ROC) curve by finding the area under curve (AUC). The main purpose of speaker identification system is to provide a reliable decision, accept or reject a speaker, given a claimed identity and a recording of a speaker phrase. After comparing area under curve we can say that the best result is shown by DWT NEO with BIC distance metric.

Abstract: Mechanical ventilation is a cornerstone in the management of severe respiratory failure. Almost all surgeries with general anesthesia require mechanical ventilation, which may trigger ventilator-induced lung injury through various mechanisms. Large tidal volume and high airway pressure may cause overextension of the alveoli, which will result in barotraumas and volutrauma. In this work, a volume-controlled ventilation system was proposed and we provide a comparison of two multi-compartment models of volume-controlled and pressure-controlled ventilation based on electrical and mathematical models. After that we present an analysis to determine whether pressure-controlled ventilation (PCV) or volume-controlled ventilation (VCV) has demonstrated advantages over control ventilation. This study can be helpful in controlled ventilation treatment and respiratory diagnostics, and very important to testing and monitoring PCV and VCV signals trigged by devices.
