At present, a trolley car is used in which people go in person to examine the railway system depending only on their vision. Mostly, these checking include detection of rail line cracks and obstacles, existence of sleepers in the proper places etc. However, the inadequacy of this kind of maintenance system is one of the vital reasons of railway accidents. The current procedure is also time consuming and costly. Besides, one of the leading causes of railway accidents is attributed to human error which can be reduced through automation. This paper attempts to improve the railway maintenance system and convert this into an automated one. Here, we are introducing a sensor based arrangement which reveals problems like surface crack, unaligned rail lines, obstacles on the railway and also inspects the correct position, presence and absence of the sleepers with the convenience of sending the location and distance to the proper authority.","PeriodicalId":6613,"journal":{"name":"2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT)","volume":"9 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79156864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed system provides the accurate FF by plotting a real-time AC power triangle in MATLAB environment. The system uses one embedded system as a controller that able to read the mainline frequency, load voltage, current and their phase difference. A preliminary circuit is used to transform the high value of voltage and current to the embedded system (ES) readable form. It consists of a potential transformer (PT), a current transformer (CT), high differential strobe terminal based comparator and logic gate that detects the phase delay between the load voltage and current. A serial communication between the ES and the MATLAB is established for plotting the power triangle which confirm the accurate PF.

They are unable to see the beauty of nature. Not all the problems of the visually impaired people can be solved but with the help of modern technology life can be made easier for them. This project, \"Intelligent Path-Finder\" tends to make life easier and less problematic. Visually impaired people use general stick for their movement but the sticks are not capable of detecting the obstacles or other objects in front of them automatically; as a result, they need to poke the obstacles to get an understanding of it. To overcome these problems, the \"Intelligent Path-Finder\" is a remarkable device which can detect various types of obstacles from knee level to ground level, for example liquid, uneven surfaces, etc. In the dark, a special feature is used to prevent accidents with the help of a glowing led light which is triggered by sensing absence of light in the environment, this light can protect the user from moving vehicles and other difficulties by drawing normal people’s attention towards it. If the user is in trouble, he can send his location by pressing an emergency switch. His family can also know the device’s location via SMS. This device consists of a microcontroller, ultrasonic sensor, light dependent resistor, etc. The combination of all these equipment together makes this device relatively accurate, user-friendly, robust and cheap. The device is not a third eye for the blind but it is significantly helpful to them by making their daily lives much easier.","PeriodicalId":6613,"journal":{"name":"2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75681479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work CdTe thin films (TF) were deposited on CdS thin films by close-spaced sublimation (CSS) technique at different source and substrate temperature in inert gas condition. To bring out the optimum temperature set for CSS deposited CdTe films, several experiments were done. The process pressure of the chamber during deposition was maintained at 1.5 Torr in a dynamic condition. The effects of deposition temperature on the electrical properties of the as-deposited CdTe films were investigated by Hall Effect measurement. The films were deposited at 610 °C, 630 °C, 650 °C and 670 °C source temperatures. The first three films showed p-type conductivity while n-type conductivity appeared in the film deposited at 670 °C. The hole concentration of the as-grown p-type CdTe films followed an upward trend with the increase of source temperature and it reached a peak value at 650 °C. The highest hole mobility was observed for the lowest source temperature. However, the resistivity of the CdTe films was found increasing with the increase of source temperature. Thus, the CdTe thin film deposited at 650 °C showed better electrical properties for solar cell applications.","PeriodicalId":6613,"journal":{"name":"2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT)","volume":"30A 5","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72750712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presently, intrusion detection systems (IDSs) are commonly using tool to detect and prevent internal and external network attacks/intrusions. IDSs are majorly bifurcated into host-based and network-based systems, and use pattern-matching techniques to detect intrusions that known as misuse-based intrusion detection system. Machine learning (ML) and data mining (DM) algorithms are widely using for classifying intrusions in IDS over the last few decades. One of the major challenges for building IDS employing machine learning and data mining algorithms is to improve the intrusion classification accuracy and also reducing the false-positive rate. In this paper, we have introduced a new method for improving detection rate to classify minority-class network attacks/ intrusions using cluster-based under-sampling with Random Forest classifier. The proposed method is a multi-layer classification approach, which can process the highly imbalanced big data to correctly identify the minority/ rare class-intrusions. Initially, the proposed method classify a data point/ incoming data is attack/ intrusion or not (like normal behaviour), if it’s an attack then the proposed method try to classify attack type and later sub-attack type. We have used cluster-based under-sampling technique to deal with class-imbalanced problem and popular ensemble classifier Random Forest for addressing overfitting problem. We have used KDD99 intrusion detection benchmark dataset for experimental analysis and tested the performance of proposed method with existing machine learning algorithms like: Artificial N eural Network (ANN), naïve Bayes (NB) classifier, Random Forest, and Bagging techniques.","PeriodicalId":6613,"journal":{"name":"2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT)","volume":"84 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74749510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, it makes a huge burden for the physicians to recognize affected portion in the real required time and it is the main obstacle for using the WCE in the wider application. For releasing the extra burden of the clinicians, we have proposed a novel automatic computer-aided system for detecting bleeding in the GI tract. In our proposed method, we have applied some special preprocessing for obtaining the required informative portions of blood. A noble Weighted k-Nearest-Neighbor (WKNN) classifier has applied for separating distinct object with some statistical features in HSV color space.

In this study the design of an experimental PVT dual system, both air and water circulation with modifications in the air channel is presented. First modification is to place a thin flat metallic sheet (TMS) inside the air channel and second one is to use painted Black ribbed surfaces at the bottom of the air channel. To observe the variations of heat transmittance with change of the shape of the ribs four experimental setups with a Trapezoidal, Saw teeth forward, a Saw teeth backward ribbed surfaces and a flat plate have been used. Natural convection is applied instead of forced convection to increase the system’s net electrical output & thereby the overall system efficiency. All setups were of the same capacity, projected area, and water heat extraction method and average depth. Performance study was carried out during the months of February to June, 2012 at IUT campus, Gazipur, Bangladesh. Significant performance has been observed with the above stated modifications. In an intense sunny day of March, the maximum temperature of water was found to be 45°C for Trapezoidal, 44°C for Saw teeth forward, 43°C for Saw teeth backward and 41°C for flat plate setup. Maximum temperature of air inside the air channel was found to be 39°C for Trapezoidal, 38°C for Saw teeth forward, 37°C for Saw teeth backward ribbed surfaces and 36°C for flat plate in an intense sunny day of march 2012 with an ambient temperature of 34°C. The average efficiency from all calculated values is found to be 64% for Trapezoidal, 62% for Saw teeth forward, 61% for Saw teeth backward and 58% for flat plate setup.","PeriodicalId":6613,"journal":{"name":"2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT)","volume":"34 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83680276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
