WWW-based remote control is an interesting and promising research field in robotics, virtual reality and visualization. Applications that have been developed in this research will find application in the management of soccer robots, space, underwater robotics, training operators, medicine, distance education, and wherever we have a dangerous environment in which man is exposed to a risk to his health. In recent years, many WWW-based robotic control systems are created. List of active systems controlled through Web search engines grow every day. Disadvantages of these systems are weak response by the steering system that is client-side. The purpose of this master's work is to create a system that is quick and easy enough for management to meet the needs of many of the operators of the systems that are managed remotely. Today, Internet technology allows conventional way to develop an integrated network environment to control various robotic systems. To be successful in real-time applications run Internet-based robots require a high degree

of freedom and autonomy with local intelligence that will handle limited bendvit and time delays that are a result of the Internet. The system has a standard network protocol and interactive man machine interface that uses a web browser to remote operator can easy and interactive way to control mobile robot. With the increase of robots and robotic applications is an increasing need to find a way through which they will be controlled remotely. Control of robots via the Internet is of particular importance because there are reliable protocols through which we receive feedback and have interaction man and machine remotely. The problem of remote control and management of robots, systems architecture and interfaces to control one or more robots in various applications is a topic of constant research in the last decade. This master thesis contributes to find innovative methods for managing multiple robots simultaneously in real time via the Internet and provides the answer to the three questions. The first question is how to make the system reliable, the second question is how to make the system fast and the third question is how to make the system open and portable. To reach it from the client-side is created graphical user interface through which you manage the desired robot and when it will have an insight into the interaction of all the other robots. The system allows exclusive control over robots by certain users. Our every action is recorded in the database and it can be further analyzed and base our actions adopted and appropriate behavior analysis system further. Through the analysis of the image from the camera which follows the movement of the robots we get the exact coordinates of the robots then the information is transmitted to the server side and stored in a database. Since there is no other application that will read the information and will display visually robots themselves. For this application we have options to control the robot with the option chosen for the release of the previous selected robot. The application will initially be in the implementation of the Football Cup of robots, and later in every production process which will have more than one robot
Internet-based Control Systems
Full text linkIn the last two decades, thousands of advanced process controls are installed in production
plants. The motivation for upgrading these systems through the World Wide Web offers
opportunities for design and analysis of systems that can be operated remotely with the
huge security and stability. In the last decade, web-based laboratories in real time play an
important role in technical education. Pilot research paper represents a practical solution
that allows through equipment that is relatively low cost to get quality monitoring and
management systems at a distance. The basic idea is to use existing technologies available
that are free to use and combined them with new solutions in this paper to make a managed
system that works flawlessly. The solutions described are characterized by short response
time at any moment and under any conditions.
For example is taken realizing the monitoring and control of the fermentation process in
existing winery. This pilot winery is operated remotely via the Internet; it is not used for
special purpose equipment. Delay information online can lead to loss of information,
because this paper shows that it takes the information provided in confidence to be saved,
when there are conditions for it and then be properly display. In a pilot research, paper
shows huge possibilities of software solutions that used for quality and flawless tracking
and management process called fermentation. For successful monitoring the fermentation
process was developed by which the sensor server module is followed by parameters and
controlling the industrial process. Through this module are recorded values of degree of
acidity marked as pH, carbon monoxide in two gases releases marked a
Controlling Computer Games through Web Camera with Motion Detection
Full text linkThe paper describes an implementation of interface for playing chess game realized through motion detection and object tracking. User hand movements are recorded with a web camera and used to move chess pieces in a given board position. We are primarily concerned with the perception and identification of user movements compared to the chess playing strategies and the game logic. The interpretation of the chessboard position and the computer next moves are performed using standard chess engine. This work contributes to the development of more natural interfaces that enable communication via user motions and gestures instead of standard computer devices
Интернет базирано управување на системи

Control and Monitoring Winemaking Process Online
No full textIn the process of wine production distributed sensor networks are used for monitoring parameters that enable constant wine quality. This paper presents an ongoing project for monitoring the conditions in the wine cellar and for controlling the wine fermentation process. Temperature and humidity sensors installed in the cellar are used to provide similar conditions for the barrels in the cellar. During the process of fermentation sensors located in the barrels are used to control the level of CO2, alcohol and temperature. The microcontroller PIC16F877A processes information obtained from the sensors and sends it to the server via Ethernet controller ENC28J60. At this moment only the on board temperature sensor is tested and is operational. We expect that data collected in the process of the exploitation of the system will be useful for the wine producers and will contribute to better quality of wines

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
