Title of the Paper: Demand Estimation Method Using Reverse Pipe Network Analysis in Water Supply Network

 

Authors: Teruji Sekozawa, Kazuaki Masuda

Pages: 292-300

Abstract: We present a demand estimation method using reverse pipe network analysis in a water supply network. In conventional method, many demand points set fixed component ratios. The objective of the pipe network analysis method using the demand estimation proposed herein is accuracy improvement on a level such that the analysis can also be applied to distribution control. We first explain pipe network analysis using a conventional method and then clarify the problems and challenges in conventional pipe network analysis. A temporal trend can be observed in the deviation of node pressure calculated using the conventional pipe network analysis method from the measured pressure. The cause of this deviation is identified as being due to the fact that the node demand in the pipe network analysis problem is supplied as a boundary condition from outside the system. Therefore, the problem considered in the present paper is the degree of accuracy with which node demand, which is conventionally supplied from outside the system, can be estimated. Next, we describe the proposed method. This is a demand estimation method that estimates node demand using measurements from pressure and flow sensors installed in the distribution network. The basic approach of this estimation method is to minimize the deviation between demand and information from pressure/flow sensor measurements, and the demand estimation problem is formulated as a deviation minimization problem. Here, the number of demands to be estimated is equal to the number of nodes, which is a very large number (several thousand). Finally, the proposed method is applied to a large-scale pipeline network of 3,000 pipes. As a result of this experimental application, the improvement rate at all of the sensor installation points increased using the proposed method, as compared to the conventional pipe network analysis method. Furthermore, the improvement rate at sensor installation points was demonstrated to more than 25% on average.

Abstract: As productive systems are becoming more complex, their control solutions are also increasingly becoming more complex. The processes of understanding and developing such systems have also become highly complex. Thus design flaws are intrinsic to their development. Even the most innovative systems are error prone and faults or accidents may cause severe damage to the operators, the plant or the environment, as no system has no fault risk. The concepts of Safety Instrumented Systems (SIS) might be a solution to this problem. However, critical systems – such as oil and gas refineries where faults may cause severe accidents – controlled by PLCs also demand a formal verification processes of their control programs and must be developed according to the safety control program development cycle defined on the IEC 61511 standard. On this work we propose a framework for the model based development of SIS control programs that is based on the cycle defined on the IEC 61511 standard and where the interaction between the prevention and mitigation programs is considered. The framework was applied to the development of the SIS control program of a natural gas compression plant (ECOMP). The framework allowed the resulting program to present a modular structure and to have several properties properly verified – considering that the final model represented the entire SIS program of a real world plant.

Title of the Paper: Tool Sequence Analysis and Performance Prediction in the Wafer Fabrication Process

 

Authors: Kittisak Kerdprasop, Nittaya Kerdprasop

Pages: 268-276

Abstract: Many modern manufacturing plants are dealing with large scale multi-dimensional data that are daily and automatically collected from hundreds of operational units in a production line. Maintaining high yield through the statistical process control as a sole monitoring method is obviously inefficient in such highly complicated operations. Recent trend in intelligent manufacturing is to apply data mining techniques to automatically identify patterns and causal relationships leading to poor yield. We thus present in this paper a sequence analysis method, which is one of the advanced data mining techniques, to identify tool patterns from the wafer fabrication processing data. The extracted patterns can reveal and differentiate low performance processes from the normal ones. We also present in this paper a feature selection technique to speed up the data mining steps and show the comparative results of performance prediction.

Authors: Ales Mizera, Miroslav Manas, Zdenek Holik, David Manas, Michal Stanek, Jan Navratil, Martin Bednarik

Pages: 260-267

Abstract: Radiation processing involves the use of natural or manmade sources of high energy radiation on an industrial scale. The principle of radiation processing is the ability of high energy radiation to produce reactive cations, anions and free radicals in materials. The industrial applications of the radiation processing of plastics and composites include polymerization, cross-linking, degradation and grafting. Radiation processing mainly involves the use of either electron beams from electron accelerators or gamma radiation from Cobalt-60 sources. The selected thermoplastic tests showed significant changes of temperature stability after radiation cross-linking. From this point-of-view, new applications could also be seen in areas with service temperatures higher than their former melting point. The temperature stability comparison of irradiated and non-irradiated materials are presented in this paper.


Title of the Paper: Risk and Hazard Control Hosted on Cloud

 

Authors: G. Florea, R. Dobrescu

Pages: 250-259

Abstract: We live in a modern industry based society where automation undoubtedly is the key for success. The technology has been changing over the last decades towards full control systems and the requirement specifications for Safety Instrumented Systems (SIS) forms the central network for the process risk and hazard assessment to be carried out. Process Control has evolved very much in the last years. Plants become more complex, they require more efficiency and reduced costs while maintaining the product quality. Advanced process control appeared to be the most effective technology to realize these objectives, but it is not enough anymore. Process control and optimization represent the current base for safer and more efficient industrial plants, while risk management represents the base for new control algorithms and strategies. There is a stringent need for the enhancement of process operations at plant production management level, because plants should often operate near criticality, meaning in conditions far from ideal ones from the point of view of control and stability. Risk and hazard control is for sure one modern approach to keep plant running even under big perturbations or uncertainty. Emerging technologies used for design and implementation; modeling, simulation, concurrent engineering, on line diagnosis, merger techniques needs big computational capabilities that Cloud can offer.

Authors: Jyri Rajamäki, Juha Knuuttila, Outi Suni, Henna-Riitta Silanen, Antti Tuomola, Päivi Meros

Pages: 238-249

Abstract: The economic pressure decreases the budgets of the first responders (FR) which in turn increases the pressure for developing novel innovations to ensure adequate computational capabilities and resources in every operative scenario. FRs’ most important tool in the field is the emergency response vehicle (ERV). The Finnish approach to provide digital services to the field for FRs is via ERVs. This multiple case study analysis collects together the research data and results with respect to ERVs from seven public safety related ICT projects. It is vital that different safety authorities develop the common ERV concept together. This enables new mobile digital services for FRs to their field operations. For example, people being first at the scene of the accident should be able to communicate with FRs who should be able to receive social media and multimedia messages into their operative systems.

Authors: Taalaybek Akunov, Natalia Dudarenko, Nina Polinova, Anatoly Ushakov

Pages: 230-237

Abstract: The steady continuous system with state matrix has real spectrum of the multiple eigenvalues which multiplicity is equal to dimension of its state vector is considered. There is shown that if the eigenvalues modulus is less than unit, in free transient motion of system on norm of state vector the oscillativity which become apparent by initial overshoot, being replaced by monotonous movement to quiescent state is found. It is established that the size of overshoot is more, than it is less the modulus of eigenvalue and more its multiplicity. Later in this article the steady continuous system which state matrix has spectrum of the multiple complex conjugated eigenvalues which multiplicity is equal to a half dimension of its state vector is considered. The special attention is paid on the situation when the modulus of real part of eigenvalue is less than unit. Is established that in this case at a small oscillativity of eigenvalues there is a noticeable overshoot in processes on norm of free transient motion on state vector and the size of overshoot more, than more its multiplicity and imaginary part and then the real component of eigenvalue and is less on the modulus.

Pages: 221-229

Abstract: In Brazil, on 2012, the export by sea was responsible for 96% (525 million of tons) of the cargo shipped abroad. According to data of October of 2013, the animal protein was the second main agribusiness product exported, reaching 16.9% (U$1,431 million) of the sector's total transactions. The optimization of the export process impacts directly on its cost, therefore, on the competitiveness of the product on the market. This article presents a technological proposal to improve and streamline the Brazilian export process of animal protein by sea. The solution is based on ITS and Secure Supply Chain concepts applied to a management system, with new operational notion. The system underlies on a customized e-Doc, named Canal Azul Eletrônico (CA-e) and technologies (media, equipment and software engineering), like RFID and PKI, which allow the field to embrace the information technology. Its impact was measured over two practical case studies, which demonstrated significant benefits when adopted the proposed technological solution.

Authors: Jyri Rajamäki, Jouni Viitanen

Pages: 215-220

Abstract: European integration has increased organized crime, e.g. the transport of illegal goods in Europe. This means that the transmitting of tracking and other status information between nations and their Law Enforcement Authorities (LEAs) should become an everyday business. The goal of this paper is to find possible bottle necks in international cooperation between LEAs and to find possible solutions for them. The following area can be considered as a part of the MACICO (Multi-Agency Cooperation In Cross-border Operations) Celtic Plus research project. The target of the paper is to present administrative and technical solutions to improve multi- organizational tracking solutions. Namely, the goal is to make it possible to create a timely situational picture in joint multinational and interagency operations. This paper will provide guidance for preparing appropriate plans and doctrine proposals for joint operations and training. Also technical solutions and bottlenecks are briefly covered in this paper.


Title of the Paper: Automatic Dosing System for Pilot Plant Production

 

Authors: Stanislav Plšek, Vladimír Vašek

Pages: 207-214

Abstract: This paper deals a design of an automatic dosing system for pilot plant. The automatic dosing of raw materials in production is important to reach of accurate amount of dosed raw materials and it saves time. The accurate amount is important to get correct result of the production or laboratory tests. The dosing systems can work with a very small amount of materials in the laboratories or huge amount of raw materials in industry production. It can work slower and more accurate in the laboratory than in an industry production, where is important fast dosing. Combination of these parameters must be chosen and used in a pilot plant. Low price, fast and cheap reconfigurations of systems are important when tests are doing. These dosing systems can work independently or they can be controlled by main unit in production system. For these purposes an automatic dosing system was designed on the base of an ultrasonic or capacitive amount measurement in liquids reservoirs. It has density temperature compensation for the higher accuracy of dosing. It saves time that is needed to manual dose of liquids, and it doses specified amount in each time when it is used.

Title of the Paper: The Approach to BIM - Building Information Modelling as Excellent Instrument for the Definition of Design Strategies and for Knowledge, Simulation and Management of the Buildings and Architectural Heritage

 

Authors: Gerardo Maria Cennamo, Stefano Savoia

Pages: 180-186

Abstract: As regards architectural heritages, especially in historic cities, the level of knowledge becomes directly proportional to the possibility of management. The qualitatively larger and better capacity for acquisition of an in-depth cognitive structure, the easier and more efficient the possibility of better management of the architectural and historical asset. The affirmation, even in the recent past, of new methodologies and cognitive and elaborative technologies, involving the natural and artificial environment has also involved areas typical of architecture by evolving traditional systems and methods of representation. When applied to the conservation, valorisation and management of the architectural heritage, especially in historic cities, the simultaneous evolution of these knowledge and technologies simulation helped evolve the discipline of representation towards a broader interdisciplinary direction, establishing a relational system of methods and leading and information that precede and complete the knowledge-analysis-design process.


Title of the Paper: GPS Navigation in Project: Way from Chaos

 

Authors: Eva Šviráková

Pages: 171-179

Abstract: This article provides project managers, the cultural events organizers, with a new approach to plan preparation and to the monitoring of events realization. The Dynamic Iteration Method introduced in this article is based on the system dynamic modelling and on the principles of project iterative development. The plan model and the reality model are structurally similar; they differ in values of exogenous variables. The research results confirm that the method is set correctly. The questions regarding the competences and observance of the project iterative development principles were given to the members of five project teams. Their answers together with the application of dynamic simulation helped establish the projects ranking. This simulated ranking was then compared with actually achieved projects achievements. It turned out that the projects ranking in the simulation fully corresponds with reality. In this way, the model validity was confirmed. Another research question is whether this method can be applied earlier than in the stage of final comparison of projects. The new approach enables to easily monitor the real project course in close connection with the plan and to take timely controlling steps. The effects resulting from the manager´s decision-making process are compared with the plan in regular iterations. Our experience in organizing cultural events proves that the application of the Dynamic Iteration Method is a chance to prevent further chaotic organizing of cultural events in companies. The method thus reminds of a traveler whose route is adjusted by a GPS navigation system.

Authors: Jyri Rajamäki, Timo Timonen, Jenni Nevalainen, Heli Uusipaavalniemi, Tomi Töyrylä, Eero Arte

Pages: 163-170

Abstract: A modern police vehicle is a very complicated combination of different technologies. A single vehicle contains dozens different human-machine interfaces (HMIs) and carries a lot of equipment; for example, Finnish police cars are equipped with an average of about 40 different HMIs and 100 different types of equipment. It is extremely important to be sure that all needed tools are available in field operations. From operational, safety and ergonomic reasons, there is a need to cut down the number of HMIs and make the systems easier and safer to use. This paper presents results from the MOBI project (http://mobi.laurea.fi) with regard to human-machine interactions in future police vehicles. The findings show the significance of the early user feedback for the design work of HMIs. The results also show that a remote identification applying RFID technology enables the police to make the inventory of their vehicles’ equipment three times faster than by hand. Based on our study, there is a global need for a standard in the HMI design for emergency service vehicle development.

Authors: Zhang Jing, He Yan, Li Ze-min, Tang Li-jian, Zhang Bin, Chen Li-li

Pages: 147-154

Abstract: For the reason that System of Systems (SoS) being composed of various elements and the inner relationships being complex, when demonstrating and evaluating the capability and efficiency of SoS, all the important factors should be organically integrated and comprehensively analyzed with the corresponding methods. Yet it’s difficult to deal with them for 4 reasons mainly: 1) the complexity of the factors being very high; 2) different methods should be provided to different factors; 3) different factors being mastered by different types of experts and in different places; 4) the inner relationship between factors being complicated either. To solve all the problems above, it’s necessary to utilize the Joint Demonstration and Evaluation Supporting Environment for SoS, i.e. JD&ESE-SoS, usually. Then all the “problem-factor-expert-method” about the SoS could be combined well. Based on analyzing the mission and requirements of Joint Demonstration and Evaluation (D&E) for SoS, the design and realization requirements of JD&ESE-SoS were studied, the disadvantages of several existing relevant systems were clarified. According to comparing the SoS characteristics with cloud computing technology, JD&ESE-SoS was designed. Finally, the practical scheme and architecture for design and realization of JD&ESE-SoS were proposed, the prototype was completed and some applications were given. It proved that JD&ESE-SoS could organize the core business flow of SoS D&E and schedule the relevant resources very well.


Title of the Paper: Using Terrestrial Laser Scanning Technology for Acquisition, Processing and Interpretation of Spatial Data from Anthropogenic Hazard and Risk Areas

 

Authors: Aurel Negrilă

Pages: 139-146

Abstract: The paper presents practical aspects for monitoring static tested constructions (bridges) and constructions subject to the current operation (dams), bringing to the forefront the possibility of using laser scanning technology. These types of construction must be continuously monitored in order to eliminate as soon the possibility of occurrence of events that can lead to disaster. In the case of buildings subjected to static tests confirmation of the viability of using laser scanning technology is done by performing simultaneous geometric leveling measurements to determine the arrow made by the construction elements. For the second type of constructions is shown the possibility of using laser scanning technology in the case when the known classical technologies can not be applied due to the disappearance of constructive elements of the monitoring network.


Title of the Paper: Method of Heating Curve Modification for Rush Hours in Practical Experiment

 

Authors: Vasek Lubomir, Dolinay Viliam

Pages: 131-138

Abstract: This article deals with method of modifying the heating curve with regard to the consideration of heat consumption in rush hour and shows possible benefits of improvements in such heating system control. For the large heat distributors in Czech Republic is common to use simple weather compensation heating curve to set temperature of heating water in their systems. In such system the heating water temperature value is directly proportional to outside temperature. Usually two curves are used, one for daytime and second for night. This many years used and proven method is easy to implement and use, however the transitions between these two curves are the possible weakness and gave rise to this research. Heating control carried out with night setback (common scheme), switch to day mode causes shocks in heat consumption. These are the rush hours in heating systems. To compensate resulting shocks by appropriate settings of input parameters is the task for smart control. With respect to analysis of the measured data, the simple modification in the existing system control were prepared and verified by simulation and practical tests. Obtained results show improved behavior, which is evident from the reduction of shock and peaks in the system.

Authors: J. Navratil, M. Stanek, M. Manas, D. Manas, K. Kyas, A. Skrobak, V. Senkerik

Pages: 108-115

Abstract: Irradiation of thermoplastics is a well-known modification used for improving cheap commodity plastics; however, little research was carried-out on recyclation of such modified materials. This research paper gives possible solution of utilization of recycled irradiated high-density polyethylene (HDPE). A powder of recycled irradiated HDPE was used as filler into a powder of pure low-density polyethylene (LDPE) and tensile test was performed. Materials were mixed together in concentrations from 10 to 60 % of the filler and injection molded to produce test specimens. Tensile test was performed at ambient - 23 °C and elevated - 80 °C temperatures. Among observed results were Young´s Modulus, Ultimate Tensile Strength and Nominal Strain to determine tensile behavior and to describe influence of the filler on this behavior. Measured results at ambient temperature show that there is significant rise of Young´s Modulus - from 239 MPa to 448 MPa, a growth of Ultimate Tensile Strength from 10 MPa to 15 MPa and on the contrary there is a drop in Nominal Strain from 62 % to 18 %. Similar trend is followed at elevated temperature; nevertheless, nominal values are lower. Findings of this research paper might help with possible utilization of irradiated materials after the end of their lifetime.


Title of the Paper: Importance of 3D Modeling Software in Urban Environment

 

Authors: Gheorghe Badea

Pages: 100-107

Abstract: In all big cities and not only in these exist a real need for urban development, because of the builded new residential areas. In all of urban decisions must be verified if all of these are designed in the same architectural style like the neighborhood: if are meeting the conditions of height, style facade, the materials and the design of the overall area, distance from surrounding buildings, not to encroach the urban rules. In Romania are very useful today these representations and to find practical possibilities for creating 3D models - with varying levels of detail. Creating of 3D urban models could be the basis of decisions taken in urban development, offering better details and informations about the real situation, being more suggestive and representing a start point to develop subsequent to 3D cadastre. All of these could not be created without a good and performant modeling software.


Title of the Paper: Investigation of the State Dependent Riccati Equation (SDRE) Adaptive Control Advantages for Controlling Non-Linear Systems as a Flexible Rotatory Beam

 

Authors: Pierre Bigot, Luiz C. G. de Souza

Pages: 92-99

Abstract: Control of flexible structures is an open problem. Such structures can be very different, for example, robot arm or satellite solar panel. The common point between these structures is their very light weight and large length. Light structure control requires less energy, smaller actuators but a much more complex control system to deal with vibrations. In this paper a flexible rotatory beam is modeled by Euler-Bernoulli hypothesis and its angular position is controlled. This kind of model is, most of the time, highly non-linear. As a result, controller designed by linear control technique can have its performance and robustness degraded. To deal with this problem, the State-Dependent Riccati Equation (SDRE) method is used to design and test a position control algorithm for the rigid-flexible non-linear model. The Matlab/Simulink simulation is based on the characteristics of real flexible link equipment driven by a DC servomotor. This work serves to show the relevance this non- linear controller showing advantages it has over a more classic LQR controller. In future work, this controller will be tested with the real rotatory beam to validate the model and the SDRE control efficiency


Title of the Paper: Effect of Ionizing Beta Radiation on the Strength of Bonded Joints and Adhesive Properties

 

Authors: M. Bednarik, D. Manas, M. Manas, M. Stanek, A. Mizera, M. Ovsik, P. Kratky

Pages: 84-91

Abstract: In this study there was found that ionizing beta radiation increased the strength of bonded joints and improved the adhesion properties of linear low-density polypropylene (LLDPE) and polyamide 6.6 (PA 6.6). Generally, for the formation of quality bonded joint it is important to wet the adhesive bonding surface well. Wettability is characterized by the contact angle of wetting. The liquid has to have a lower surface tension than the solid in order to be able to wet the solid substance. The measurement results indicated that ionizing beta radiation was a very effective tool for the improvement of adhesive properties and increased the strength of bonded joints of studied polymers. Bonded surfaces with ionizing beta radiation doses of 0, 33, 66, and 99 kGy were irradiated. The best results were achieved by irradiation at doses of 66 and 99 kGy by which the highest surface energy and the highest strength of bonded joints of LLDPE and PA 6.6 were achieved.


Title of the Paper: A Redundant Tracking System for Public Safety and Emergency Response: Reporting Past Research, Present Findings and Future Directions

 

Authors: Jyri Rajamäki, Paresh Rathod, Pasi Kämppi

Pages: 76-83

Abstract: Tracking is playing very significant role in modern public safety and emergency response. There are many tracking technology available. Such as the geographic information systems (GIS) and global navigation satellite systems (GNSS) have transformed local, national and international emergencies and disasters response services. GIS/GNSS technologies offer great deal of assistance in public safety and emergency response enabling emergency management agencies to efficiently allocate resources, model risk and direct emergency response and recovery personnel. On the one hand, these technologies are bringing many innovative advantages to organizations responsible for public safety and emergency response. While on the other hand, it brings many challenges. For example, current GNSS-based tracking systems have serious technical flaws and vulnerabilities. This paper is reporting our research studies conducted in various projects and it also presents our finds including a detailed modular system-level description for a hybrid tracking system including control, space, tracking, communication, data processing, end-user and external applications segments. The paper further discusses and suggests how the technical vulnerabilities of GNSS-based tracking systems could be avoided considering hybrid tracking segment and multichannel communication paths. The paper is also exploring future possibilities to provide smooth tracking for public safety and emergency response.

Authors: Elcio Brito da Silva, Sergio Luiz Pereira, FabrizioLeonardi, Maria Lídia Rebello Pinho Dias

Pages: 62-75

Abstract: The growing demands for industrial products are imposing an increasingly intense level of competitiveness on the industrial operations. In the meantime, the convergence of information technology (IT) and automation technology (AT) is showing itself to be a tool of great potential for the modernization and improvement of industrial plants. However, for this technology fully to achieve its potential, several obstacles need to be overcome, including the demonstration of the reasoning behind estimations of benefits, investments and risks used to plan the implementation of corporative technology solutions. This article focuses on the evolutionary development of planning and adopting processes of IT & AT convergence. It proposes the incorporation of IT & AT convergence practices into Lean Thinking/Six Sigma, via the method used for planning the convergence of technological activities, known as the Smarter Operation Transformation (SOT) methodology. This article illustrates the SOT methodology through its application in a Brazilian company in the sector of consumer goods. In this application, it is shown that with IT & AT convergence is possible with low investment, in order to reduce the risk of not achieving the goals of key indicators.

Port terminals play an important role in connecting transition between the unit and shipping and land transport must be efficient and fast in their services to reach productivity levels compatible, since the expected increase in cargo handling. Information technology and communication can help computerize the operation processes of the terminal, by introducing concepts of monitoring and management, and the introduction of devices that can collect information in real time and thus reduce time and improve quality in services. A point of attention is that the port terminal consists of various activities and operational procedures that are interconnected, so that the applied technology requires great efficiency, because a failure in one component affects the entire value chain.

Abstract: Little research was done to investigate possible utilization of the irradiated materials after the end of their lifetime despite the growing potential of modification by irradiation. This research paper deals with usage of this recycled material as filler into non-recycled one. A powder or a grit of recycled irradiated high- density polyethylene was used as filler into non-irradiated powder or granules of low-density polyethylene. Three types of compounds were prepared – each with the same concentrations. These were from 0 % to 60 %. Notched Charpy Impact Test was then performed at ambient conditions and influence of this filler was tested. Two parameters were observed – Maximum Force (force needed for breakage of the material) and Impact Toughness (describing impact behavior of the material). Measured results show minimum influence on Maximum Force in cases of powder filler – it varied around 280 N. In case of grit filler it grew rapidly with increasing concentration – from 286 N to 348 N. Results of Impact Toughness are much more consistent because all three compounds show similar trend. In all cases was this trend decreasing – the higher filling level the lower Impact Toughness. These findings are showing the way of possible re-use of irradiated materials.

Abstract: Nowadays, in Romania a great accent is placed on the development and improving of both the modern road and railway networks that should offer superior comfort, safety and efficiency in traffic and should respect current policies in sustainable development. It is also known that a modern and sustainable transport infrastructure represents the development “engine” for national economy, thus allowing the enhancement of economic sector, the expansion of economic competition and integrating the national Romanian economy into the European and worldwide economy. In this context, the surveyor engineer, beside his quality of supplier of measured geometric data, has a significant contribution, through his abilities regarding modeling of dynamic systems like constructions or roads and data interpretation. An eloquent example is represented by the present paper, in which the authors describe the methodology for achieving the geodetic support network used for the rehabilitation of the Sighişoara-Aţel railway section, part of Pan-European Corridor IV.

Pages: 18-25

Abstract: In this contribute we propose an application of a new algorithm for least squares matching of overlapping 3D surfaces that we sampled point by point using a terrestrial laser scanner. The studies on the absolute orientation of stereo models using DEMs as control information are known as DEM matching. The proposed method estimates the transformation parameters between two (or more) fully 3D surface patches and minimizes the Euclidean distances instead of Z-differences between the surfaces by least squares. The application in question is aimed, in the study of deformations of mountain areas, as well as test the TLS applied to a hilly area. For this purpose, it was also tested using the algorithm LS3D “Least squares 3D surface matching” that allows both the registration of point clouds produced by scans carried out without using targets but, overall, the estimate of deformations that in this case, compared to other methods, is done directly on the basis of the two data sets acquired in two different eras.

Abstract: The use of embedded hardware and software are growing in the automotive applications. However, the development effort required is increasing at the same time that schedule is becoming tight. In this paper we present a methodology for the development of embedded systems suited to the dynamics of the automotive sector. We propose a development framework that adds the concepts of component-base software engineering, reusable hardware platforms and pair-wise testing techniques. The effectiveness was evaluated through a case study of developing a telematic module. Development cycle of automotive embedded system can be accelerated by using framework.


Title of the Paper: Construction of Equipment for Creep Behavior Study

 

Authors: M. Reznicek, V. Senkerik, V. Pata, M. Stanek, A. Skrobak, K. Kyas, D. Manas

Pages: 1-8

Abstract: This article describes the design of devices for measuring creep, in which commercial measuring instruments are used and which allows the measurement of creep at elevated temperatures. Detailed design of the entire device is described, including examples of possible outcomes. The device is designed to measure up to four samples simultaneously and these samples can be loaded with different weight which increases the variability of the equipment. The whole device is designed to be manufacturable in workshops with minimum machinery and thereby reduces the overall cost. Finally the device tested samples PA6.6 and radiation crosslinked filled PP samples.
