In the conditions of industrial production many processes of polymerisation are nonstationary. By processes optimization with the regard for such features as basic data it is necessary to use adaptive algorithms of identification, allowing mathematical model of process continuously to be adapted for changing conditions of operation. Use of such algorithms for process optimization demands periodic recalculation of optimum technological modes of process. Polymer reaction engineering is a discipline that deals with various problems concerning the fundamental nature of chemical and physical phenomena in polymerization processes. Mathematical modeling is a powerful tool for the development of process understanding and advanced reactor technology in the polymer industry. © (2013) Trans Tech Publications, Switzerland.

Visually impaired people encounter several challenges in their mobility and navigation. Their daily activities are obstructed due to their inability to adapt or recognize accurately their surroundings, especially outside their house which they are more familiar with. Thus, it becomes the main reason of accidents, falling off, getting lost in unknown areas, etc. Furthermore, one of the sensory systems that helps the body to process data about the external environment is the visual system. Blind people also lose touch with the outside world, develops poor motor habits, which results in postural problems as a result. This project will assist visually impaired people in their daily life and simplify normal tasks through a system combining two previously designed projects, 'Smart Shoes for Blind and Visually Impaired People', and 'Human posture monitoring device'. The multifunctional system is developed with the goal of securing safe movements for visually impaired people as well as maintaining a good back posture by detecting leaning postures (LP). The purpose of the smart shoe is to identify obstacles and protect the user from unintended accidents. A compatible Android application has been developed to alert the user when there is an obstruction or when he is walking on a wet surface. Voice alarms will be used to acoustically alert the user. If the user collapses, a message with their position will be sent right away to a relative. On the other hand, the smart vest will identify the position of the user's back and alert him to maintain a straight posture through the same application as well. As the system is dealing with human health, some safety measurements would be taken into consideration to implement a safe electrical system in order to reduce error and to increase accuracy. © 2023 IEEE.

This paper presents a novel approach of using unmanned aerial vehicles (UA Vs) to establish a communication infrastructure in case of disasters. Due to the collapse of buildings, power systems, and antennas, the collapse of communication infrastructure is the usual effect of disasters. In this study, we propose an emergency communications system established by unmanned aerial vehicles (UA Vs). The system is a post-disaster solution; hence, it can be used anywhere required. In this study, first we briefly explain the details of the system in three aspects: end-to-end communication, localization and navigation, and coordination Then, we evaluate the efficiency of the localization and navigation subsystem. Our simulation studies with Air Robot quadrotor helicopters in Unified System for Automation and Robot Simulation (USARSim) simulation environment show that UAV-aided communications system can be used in case of disasters to establish an emergency communications infrastructure in terms of localization and navigation.

作者： Gurkan Tuna Kayhan Gulez Department of Computer Programming Trakya University Edirne Turkey Department of Control and Automation Engineering Yildiz Technical University Istanbul Turkey

This paper presents design considerations of indoor and outdoor navigation techniques proposed for unmanned vehicles (UV). In this paper, we mainly investigate the use and the advantages of wireless sensor networks (WSNs) for indoor navigation, and Global Positioning System (GPS) for outdoor navigation. The system primarily uses laser range finder (LRF) measurements for indoor navigation, and is based on Extended Kalman Filter (EKF). For outdoor navigation the system uses Inertial Navigation System (INS) measurements. At periodical intervals the system integrates the measurements of an absolute sensor to improve estimations. The absolute sensor is a WSN interface for indoor navigation, and a GPS receiver for outdoor navigation. Simulation studies were conducted using Unified System for Automation and Robot Simulation (USARSim) and Player/Stage. The results of USARSim based simulations prove the advantages of integrating GPS measurements. Player/Stage based simulations show the advantages of integrating Received Signal Strength Indicator (RSSI) measurements obtained from WSN interfaces. In addition to the simulation studies, field tests with a custom-built Corobot autonomous robot platform will be realized to prove the effectiveness of the methods.

The article proposes a method of zero-watermarking for colored RGB bitmap images. This algorithm can be used to protect property rights to multimedia resources in which it is impossible to use ordinary watermarks due to the impossibility of changing the image (such as medical data where high accuracy is required and the appearance of artifacts is unacceptable) or due to the presence of a higher distortion of the container. This algorithm is based on DWT, SVD and operations in the field by modulo 256. The software implementation of the algorithm was developed (using the Accord and *** libraries to implement DWT, SVD). The software implementation of the algorithm was tested. This algorithm has advantages in the form of normalization of the average error, but it needs further research to improve its performance.

The multilevel inverters (MLIs) are classified into three topologies such as Diode Clamped, Flying Capacitor and Cascade Multilevel Inverter (CMLI). CMLI topologies include two kind of structure that is named symmetric and asymmetric topologies. Asymmetric Cascade MLI (ACMLI) topologies consist of unequal DC sources. Many modulation techniques have been used in ACMLI topology such as Multi-Carrier PWM (MC-PWM), Space Vector PWM and Selective Harmonic PWM. The MC-PWM technique is achieved by four different types. In this study, MC-PWM techniques which are named Phase Disposition PWM, Phase Opposition Disposition PWM, Alternate Phase Opposition Disposition PWM and Phase Shifted PWM have been compared. It is uncovered that Phase Opposition Disposition PWM technique is more convenient in terms of Total Harmonic Distortion of output voltage and current signals and in terms of the quality of power factor in ACMLI which is performed in this study. © 2013 IEEE.

This work presents the performance of WLAN and MANET networks using the auto-configuration of Mobile IP Agents Protocol (DRMIPA). This scheme would allow groups of MIP nodes in WLANs or MANETs to enjoy IP mobility at any foreign or local network that doesn't implement MIP. To maintain a failure free MIP network, a passive agent is elected from an active agent if this active agent leaves or ceases its participation from current network. The DRMIPA protocol is implemented in WLAN and MANET. A performance analysis is done using a real world testbed scenario.

In pattern recognition, depending on how the training sample is represented, a theory associated with the standard representation of the training sample (information) and the structural theory are distinguished. In the first case it is convenient to set and describe objects that are independent of each other, objects that have a rigid, static nature. In the second case, when information is specified in a structural way, it is convenient to study, describe and recognize objects whose basis presents an invariable internal or external structure. This paper considers a fundamentally different case of setting learning information. It deals with objects and processes that are based on conflict. Such features are peculiar to the data sets that an unmanned vehicle receives while driving, which requires minute-by-minute formation and decision-making in the context of the current traffic situation. Naturally, it is necessary to involve game-theoretic models to describe conflicts. It is these issues, i.e., the systematic study of game-theoretic models in the problems of recognition and classification, that the work is devoted to. It is emphasized that the classification of recognizable objects, as some speculative system, must meet the requirements of sufficiency of grounds and coverage of the totality of existing and possible recognizable objects. The most important purpose of classification is to describe the properties of its classes and subclasses, types and subspecies of recognized objects, which makes it possible for it to be used for recognizing specific objects, which subjects encounter in certain areas of activity. The paper introduces the concept of stable classification, formulates and proves the theorems based on the introduced concept, the sufficiency of the conditions for the correctness of the algorithm of pattern recognition, using the game-theoretic approach and evaluation of the degree of stability of the classification underlying it.

作者： GALLAHUE, JS THE AUTHOR is the Department Manager of Combat Systems Engineering at Litton Industries. Data Systems Division. Prior to joining Litton Industries he was associated with UNIVAC. Since joining the Combat Systems Community in 1959. his assignments have included operational computer programming field engineering systems engineering equipment design proposal management test engineering. and programs management. In these varied roles he supported the NTDS R&D Program NTDS Service Test Program Interim Fleet Programming Center Pacific Anti-Submarine Warfare Ship Command and Control Systems SQS-26/NTDS/UBFCS Interface Design DD 963 Class LHA 1 Class. and the DDG 993 Class.

The required configuration management and the necessary control of the Surface Ship Combat System elements demand that they be considered as integrated and tested in accordance with an integrated test plan utilizing an integrated test organization. The sometimes used approach of implementing a combat system test program based upon the individual combat system elements being independent, has proven to be less than satisfactory. Then is no question that some of the early testing at the unit, subsystem, and subprogram levels can be planned and conducted independent of a specific “end-item” combat System. This paper addresses the planning and implementing of combat system test with the emphases being upon the integrated phase of test and primarily the lead ship of a class. Information is presented to facilitate planning and implementing a combat system test program including use of shore facilities and integrating these activities with shipboard activities; when to form the test organization and what types of expertise are required; what are the key technical management tools; the proofing of test documentation; the need for detailed “step-by-step” procedures and traceability of the specified requirements; how to assist Ships Force; planning and stat using the conduct of the tests; integrating computer program and special testing into the test program; and the significance of early decisions on administrative and contractual arrangements.

OMG's (Object Management Group) CORBA (Common Object Request Broker Architecture) is becoming a common platform for distributed computing environment. However, it is yet to address CSCW (computer Supported Collaborative Work) ftamework. This paper addresses the problem of building a framework for CSCW and proposes a new CSCW framework based on CORBA (CFC). CFC includes session, participant, mode, directory, stream, media and resource management. A desktop conference system and DSM-CC compliant video-on-demand system were built to demonstrate the usefulness of the framework. The performance of CORBA based CSCW applications is given. The strengths and weaknesses of using a CORBA framework are also discussed. © 1997 IEEE.
