This is a very focused study looking for specific information relevant to the study topic.  The paper relied on both qualitative and quantitative methods through collecting the data relevant  to the paper topic using the survey approach with employees in the warehouse and the semi-structured interview with the Human Resource Department (HRD) in three organizations. Obtaining views from both HRD and the employees in the warehouse function concluded that  there is a gap between employees' expectation and organizations' policy & procedures, and  there is also a gap in communication between employees and HRD.","PeriodicalId":360729,"journal":{"name":"Automation and Autonomous System","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116052347","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}

This data can be structured, semi structured or unstructured. To perform efficient mining of valuable information from such type of data the big data technology is gaining importance nowadays. Data mining application is been used in public and private sectors of industry because of its advantage over conventional networking technology to analyze large real time data. Data mining mainly relies on 3 V’s namely, Volume, Varity and Velocity of processing data. Volume refers to the huge amount of data it collects, Velocity refers to the speed at which it process the data and Variety defines that multi-dimensional data which can be numbers, dates, strings, geospatial data, 3D data, audio files, video files, social files, etc. These data which is stored in big data will be from different source at different rate and of different type; hence it will not be synchronized. This is one of the biggest challenges in working with big data. Second challenge is related to mining the valuable and relevant information from such data adhering to 3rd V i.e. Velocity. Speed is highly important as it is associated with cost of processing. On the other hand, mining through the high dimensional data the search space from which an optimal feature subset is determined and it is enhanced in size, guiding to a difficult stipulate in computation. With respect to handle the troubles, the research work is generally based on the high-dimensionality and streaming structure of data feeds in big data, a new inconsequential feature selection methodology that can be used to identify the feature selection methods in the big data. Some of the research work illustrates the different kinds of optimization methods for data stream mining would lead to tremendous changes in big data. This research work is focused on discussing various research methods that focus on finding the efficient feature selection methods which is used to avoid main challenges and produce optimal solutions. The previous methods are described with their advantages and disadvantages, consequently that the additional research works can be focused more. The tentative experiments were on the entire research works in Mat lab simulation surroundings and it is differentiated with everyone to identify the good methodologies beneath the different performance measures.","PeriodicalId":360729,"journal":{"name":"Automation and Autonomous System","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134022591","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}

It is important to know the fundamental natural frequencies of the system to analyze how a system vibrates under external excitations. The aim of the present paper is to perform find the natural sloshing frequencies of liquid filled containers experimentally and numerically. A swine sweep test is carried out on a shake table to find the slosh frequencies experimentally. Finite element technique is employed to solve slosh frequencies numerically. The governing equation of motion of the fluid is considered homogeneous, isotropic, inviscid and incompressible. The governing equations are expressed in terms of the pressure variable alone. The numerical natural frequencies of sloshing are calculated using 3D finite element model. The liquid domain is discretized using eight-node isoperimetric brick elements. Sloshing frequencies obtained from experiment and numerical model are in excellent agreement. The sloshing frequencies obtained are also compared with analytical solution available in literature and found to be in good agreement.","PeriodicalId":360729,"journal":{"name":"Automation and Autonomous System","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122742632","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 accelerometer and gyroscope are modelled with inter axis misalignment correction. To determine calibration parameters of a tri axis accelerometer at least nine equations will be required to solve for nine unknowns (3 scale factor, 3 zero bias, 3 misalignment angles). In this simple approach three new linear equations were formulated to determine the calibration parameters thereby reducing number of positions needed in multi position test. The formulated methodology for accelerometer is validated by conducting twelve position tests. All combination of positions were attempted iteratively. After identifying the singularities, the study on the results suggests that only six positions are enough to solve nine unknowns. Similar methodology was applied to calibrate tri axial Gyroscope in rate test. Rate test results were studied and analysed with standard values provided my sensor manufacturer. A strap down inertial navigation system (SINS) error model is introduced, and the observability of the SINS error model is analyzed. Then on the basis of this SINS error model and a kalman filter is used to estimate the states of the error models. Based on the analysis of computer simulation results, a fast and precision initial alignment method is proposed for SINS on stationary base.","PeriodicalId":360729,"journal":{"name":"Automation and Autonomous System","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127175533","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}

Self tuning of PI controller was achieved by adapting PI controller gains with system parameters by using Bats Echolocation controller which mimics the Bats Echolocation behavior. In the proposed controller, the system voltage (parameter) at point of common coupling compared with reference voltage and then Bats Echolocation Controller updates the PI controller gains according to the variation obtained between them.

LDR (Light Dependent resistor) is a type of sensor which actually does this work and senses the light as our eyes does. As soon as sunlight comes, visible to our eyes it automatically switches OFF lights. Ultrasonic sensor are used for object detection. As soon as an object comes into the range of ultrasonic sensor the lights will be turned ON automatically. And so it can be also used for regulating traffic signals and also can be used for alarming if any accident has occurred. If the object stays in the range of ultrasonic sensor for more than particular time then it sends the flag signal to server regarding it and based on the flag the server instruct to regulate traffic signals or alarming the officials about the misshaping in highways .
