 Abstract

Mental stress is a major issue nowadays, especially among youngsters. The age that was considered once most carefree is now under a large amount of stress. Stress increase nowadays leads to many problems like depression, suicide, heart attack, and stroke. In this paper, we are calculating the mental stress of students one week before the exam and during the usage of the internet. Our objective is to analyze stress in the college students at different points in his life. The effect that exam pressure or recruitments stress has on the student which often goes unnoticed. We will perform an analysis on how these factors affect the mind of a student and will also correlate this stress with the time spent on the internet. In this paper, hybrid algorithm is proposed which combines Tf-Idf with Multinomial Naive Bayes and Tf-Idf with SVM. This can be reduced to an extent if such intimidating messages or comments are segregated. The process of classifying a sentence whether it is positive, negative or neutral is known as sentiment analysis. It helps in determining emotional tone behind a sentence. To classify these intimidating messages this paper proposes a Tf-Idf with Multinomial Naive Bayes and Tf-Idf with SVM approach which classifies reviews into positive or negative.

 Abstract

In this paper, in order to optimize the dynamic performance Of the permanent magnet synchronous motor (pmsm) Speed regulation system, a nonlinear speed-control algorithm for The pmsm control systems using sliding-mode control (smc) is Developed. First, a sliding-mode control method based on a new Sliding-mode reaching law (nsmrl) is proposed. This nsmrl Includes the system state variable and the power term of sliding Surface function. In particular, the power term is bounded by the Absolute value of the switching function, so that the reaching law Can be expressed in two different forms during the reaching Process. This method can not only effectively suppresses the Inherent chattering, but also increases the velocity of the system State reaching to the sliding-mode surface. Based on this new Reaching law, a sliding-mode speed controller (smsc) of pmsm Is designed. Then, considering the large chattering phenomenon Caused by high switching gain, an improved anti-disturbance Sliding-mode speed controller(adsmsc) method, called Smsc+eso method, is developed. This method introduces an Extended state observer (eso) to observe the lumped disturbance And adds a feedforward compensation item based on the Observed disturbances to the smsc. Finally, simulation and experimental Results both show the validity of the proposed control Method.

 Abstract

For any medical diagnosis, to predict the lung diseases and for medication purposes which are needed to cure or to prevent the lung diseases, medical scans are used in the diagnosis stage. In order to do this, it is a prerequisite step to provide an accurate lung CT image analysis such as lung cancer detection. Traditional method follows with human interaction where the doctor is supposed to examine the lungs region from the CT scan images of the lung. This may lead to several errors in predicting the disease or in medication that is to be given to the patient.This can be overcome by using the computer technology image segmentation where lung CT scan images can be segmented based on the requirement. In this project, lung CT image segmentation is proposed by U-Net architecture rather than segmenting with the traditional algorithms which are already implemented.

 Abstract

The main objective of this project is analysis for the crucial situation occurs in the automatic train system. In the railway surveying in many accidents cause multiple damage for life and also our property. So that this project to implement in two ways to save the train travel. For the one way is to determine the malicious in the train track incessantly, whether the track stipulation is good or not for use the vibration Sensor to check it. Next for them to avoid the obstacle crossing in train track, when the train is come. The main aspire in this project is to help our railway department to improve the automatic process. Also develop the requirement tools needed in that safe travel. But still the train collisions occur in may place not yet decreasing one. To control the main region in train system have been the gate level operation to using stepper motor in real time analysis. This is accurately done by using the proteus tool to get the better result.

 Abstract

Precast concrete is well known technology in which some Standardized units which are manufactured in factories are used for fast Construction. Though the technology is developed many years ago but the Implementation is not up the mark in our country. In this study we have carried out detailed study of various concepts of precast, go through number of Literature & found the facts associated with it. Existing reinforced concrete Structures stock is wide and also includes buildings with precast elements, being largely used since Fifties primarily to satisfy needs of the manufacture and tertiary purposes. Their diffusion has been supported by flexibility of structural net dimensions and by the economy and efficiency of the constructional process. For this purpose, a reference project at Chennai location is taken and modelled in SAP2000 software to analyses the structure and design.
