Colour Detector and Separator Based on Microcontroller
No full textSorting of objects is one of the most important tasks in the industries. Sorting machines can be made by using the sensor, camera, microcontroller and image processing system, etc., based on colour, size and shape of the objects. Among these systems, colour sorting machines are widely used in most industries to sort various coloured objects. This thesis describes the design and implementation of colour detection and sorting machine by using Arduino, colour sensor and two servo motors. In this system, a top servo motor is used for placing the object to the colour sensor which detects the RGB values of the object and then sends the information to Arduino. Then bottom servo motor will move according to the angle of respective degree which is command in the code depending on the RGB values of the object and then the object which is over the slider drops into the container. Servo motor is used to substitute the human operator and Arduino is used to controlling the overall process.

Liquid Level and Photoelectric Sensors Based Automatic Liquid Mixing and Filling Machine System using PLC
No full textToday the application of PLC is more widely used in the digital world. There are many applications of PLC especially in the industrial. Normally, the PLCs that have been used at the industrial field are usually to control the machine or heavy machine in order to create an efficient production process. In this paper, a discussion about PLC application will be explained in more details and specified. A machine that uses to prepare automatic liquid mixing and filling machine system is controlled by Delta PLC which is also the heart of the entire system. The DVP 14SS2 from the Delta PLC types is used and WPL soft is used to write the ladder logic. The PLC can control many other electronic devices such as pump motor, level sensors, photoelectric sensor, conveyor belt, gear motor, solenoid valve, push buttons, relays and other devices. The main aim of the paper is to develop and test the real time implementation of PLC based liquid mixing and filling machine system. Firstly, start button is pushed. The liquids juice and water are mixed in the mixer tank by using valves. The level sensors know limited liquid levels and mixer motor starts stirring. The mixer motor is ON by timer. When the stirring process stops, the conveyor belt starts moving. When the cup passes photoelectric sensor, conveyor belt stops and then the pump motor fills the liquid mixture in the cup by timer. When the cup completes filling process, the pump motor closes and conveyor belt runs continuously. When another cup passes the photoelectric sensor, conveyor belt stops. Filling process operates again and again.

Four IR Sensor Based Automatic Control of Railway Gate using Microcontroller
No full textThis paper investigates based on four IR sensor automatic control of railway gate using a microcontroller system. There are so many railway accidents happening due to the carelessness in manual operations or lack of worker. So, this paper describes four IR sensor based automatic control of railway gate system for saving precious human lives and preventing major disasters in railway track. Railway gate may be saved for the road users to prevent accidents in terms of train speed at a level crossing. Automatic railway gate control system is an innovative circuit which automatically controls the operation of railway gates detecting the arrival and departure of train at the gate. This automatic system can be replaced by the gates operated by the gatekeeper. The operation using Arduino UNO that integrated with other circuits involved such as power supply, IR sensors, light indicators, buzzer, and gate motors. The servo motor is used to control the open and close status of the railway crossing gate. The four IR sensors are placed on the railway tracks. The gate is closed when the first one senses the train and is opened when the second one senses the train. This operation is performed when the train is coming from the left side of the gate. When the train is coming from the right side, the third and fourth sensors is performed in the same operation. The red LED is HIGH when the gate is closed and the green LED is HIGH when the gate is opened. This system is based on software programming to operate the hardware structure. Program for four IR sensor based automatic control of railway gate system is based on Arduino UNO with C language. The main function of the design is Arduino UNO.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
