Title of the Paper: CFAR Detectors for DVB-T Passive Radar in Non-Homogeneous Scenarios
Authors: N. del-Rey-Maestre, D. Mata-Moya, J. Rosado-Sanz, P. Gomez-del-Hoyo, M. P. Jarabo-Amores
Pages: 340-350
Abstract: CFAR (Constant False Alarm Rate) detectors were designed and evaluated in non-homogeneous DVB-T (Digital Video Broadcasting-Terrestrial) passive radar scenarios. The CA-CFAR (Cell-Averaged CFAR) is the most widespread incoherent CFAR technique. CA-CFAR detector is optimal under the assumption of homogeneous interference, but CA-CFAR performance is degraded when this assumption is not fulfilled. As an attempt to design CFAR algorithms in non-homogeneous environment, VI-CFAR (Variability Index-CFAR) was proposed. CA-CFAR and VI-CFAR detectors were designed and evaluated in a simulated and real passive radar scenarios. The real data were acquired by IDEPAR demonstrator, a DVB-T passive radar system. Results confirm the suitability of VICFAR based solutions in passive radar scenarios providing detection probabilities much higher than the detection capabilities associated with CA-CFAR.
Title of the Paper: Two-Stage Algorithm for License Plate Extraction
Authors: Marko Lukic, Milan Tuba, Raka Jovanovic
Pages: 335-339
Abstract: License plate recognition is an important practical problem with many applications in intelligent transport systems. The most important step is license plate extraction since recognition can be done by commercial character recognition systems. License plate extraction is a hard problem due to many variations in images including distance, angle, illumination, color of the plate, etc. In this paper we propose two-stage algorithm for license plate extraction. The first stage uses dynamically adjustable thresholding for determining potential license plate areas. The second stage uses vertical edge density, contrast information and entropy to extract license plate from other candidate regions. Our proposed algorithm was tested on standard benchmark images and it successfully extracted license plates.
Title of the Paper: Calibration of Nonlinear Radix in Pipelined Analog-to-Digital Converters Using a Correlation Algorithm
Authors: Hamed Aminzadeh, Morteza Rajabzadehy
Pages: 330-334
Abstract: The devices used in current integrated circuits technology are mostly non-linear. This issue makes the matching between such devices almost impossible. In pipelined analogto- digital converters (ADC), this implies that achieving to the accuracies more than those allowable by the error sources is impossible without using an effective calibration technique. It can be shown by simulations that the number of the front-end stages that should be calibrated is larger than the difference of the maximum achievable bits without calibration and the required bits of the converter. In this paper, a discussion is provided on the modeling of the important error sources of the pipelined ADC in gain of the stages, and then, a novel approach is proposed for the non-linear calibration of the ADC stages.

Authors: Vesna Baltezarević, Radoslav Baltezarević, Borivoje Baltezarević
Pages: 324-329
Abstract: People passing through various stages of development of human society reacted differently to the changes that have transformed their way of life. With the advent of computers and the Internet, a technological leap in the human community took place, laying the foundations of a new, parallel virtual world. The need for communication, as well as the challenge sets sail for the inexhaustible virtual landscapes and typing of the feelings on the keyboard, is opening a recently initiated odyssey quest for answers. Modern technologies have significantly contributed to the redefinition of communication, and the transition to the techno sphere is carried out with the support of IT network which increases the risk of value systems conditioning. The benefits of the Internet are great, but only when it is understood as a tool, and not as an instant replacement of real life. Virtual world offers pleasure to a communicator, but a significant part of the online media space is still not covered by the legal regulations which lead to numerous violations of human rights, but also to serious criminal acts which remain beyond the reach of the law. The aim of the regulation of new media should be directed towards setting up a solid foundation on which they will be able to build methods for the defense of human dignity and privacy in the context of cyberspace.

Title of the Paper: Development of High Voltage Module for an Electrostatic Painting Robot System
Authors: Jun-Hyuk Choi, Byong Jo Hyon, Joon Sung Park, Jin-Hong Kim
Pages: 315-319
Abstract: The electrostatic painting system is widely used in many industry applications. The electrostatic painting system projected charged paint particle toward conducting bodies. Paint particles were highly accelerated during projection process, because of electrostatic charges. Electrostatic painting process takes advantage of the principal of physics to achieve better coverage and to lessen the environmental impact by allowing smaller amounts of chemicals to be used. In this system, a high voltage module is essential component. The high voltage generates electrostatic field used to accelerate projection toward conducting bodies. The high voltage module is composed of voltage multiplier and transformer. In this paper, the development of voltage multiplier and transformer in high voltage module was described. The simulations results are described using PSIM tools. In addition to, experimental results from a laboratory prototype are presented to validate the feasibility of the proposed electrostatic painting system

Title of the Paper: Development of LLC Resonant Converter for an Electrostatic Painting Robot System Using a High Voltage Module
Authors: Byong Jo Hyon, Joon Sung Park, Hyuk Choi, Jin-Hong Kim
Pages: 291-295
Abstract: A LLC resonant converter can achieve wide operation range with high efficiency. In the LLC converter, a wide range of output power is controlled by a narrow variation in operating frequency. For these advantages, the LLC resonant converter is used widely in industrial applications. Especially, in an electrostatic painting system, the LLC resonant converter is combined with high voltage generating module and controlled by a variable frequency to adjust wide output load. This paper presents development of the LLC resonant converter for electrostatic painting system. Experimental results from a laboratory prototype are presented to validate the feasibility of the proposed electrostatic painting system.
Title of the Paper: Aspects Regarding the Importance of Maintaining the Independence of Elderly Through the Relationship Between Morbidity and Anthropometric Indicators
Authors: N. Ciuciuc, B. A. Năsui
Pages: 286-290
Abstract: As we get older, our body undergoes changes that occur gradually and inevitably progresses over time, but the rate of progression is very different from one person to another. One of the most important factors influencing quality of life in the elderly is to maintain aerobic capacity and independence in daily self-care. This study has followed the relationship between anthropometric indicators and morbidity of two lots of elderly - institutionalized and non-institutionalized. The used anthropometric indicators were skin folds at several levels, height and weight. Also, the study has determined the percentage of fat mass by bio-electrical impedance method. Morbidity data were collected from medical records of elderly. While evaluating the anthropometric data in relation with the elderly's pathology, it was observed that non-institutionalized elderly - by maintaining their social life - had better values for muscle mass and the pathology is less severe. Also the number of illnesses associated to one person is lower. These differences can be explained if we consider that the institutionalized elderly physical activity is extremely low, either due to lack of equipment (there are few institutions equipped with a gym), either because of associated chronic diseases which further limits exercise capacity.

Title of the Paper: Processing Speckle Images to Improve Quality of Residual Stress Measurements by HDM-ESPI
Authors: C. Barile, C. Casavola, G. Pappalettera, C. Pappalettere
Pages: 270-273
Abstract: Industrial processes which lead to the creation of the final components are potential sources of residual stresses. Any kind of manufacturing process, in fact, as welding, forging, casting ecc. introduces a given stress state in the component that it is not easy to foresee. Many experimental techniques have been developed along the years in order to have an accurate evaluation of the residual stress state. Equipments and techniques have strongly evolved along the years and new approaches are also taken into account currently. Among the innovative procedure for residual stress evaluation, one of the most interesting one is HDM-ESPI that can be considered a direct evolution of the well consolidated hole-drilling method. This is a powerful approach consisting in detecting, by an optical interferometric technique, the displacements field around an hole drilled in order to get local stress relaxation. However quality of the recorded images can affect the reliability of the measurement. In this paper some considerations on pixel quality are presented along with some indications about the proper choice of the internal radius of analysis. It will be demonstrated that, from a practical point of view, the quality of the image can be diminished by the production of some fine dust that sticks to the surface altering the speckle pattern. As a consequence it will be seen as a proper choice, of the pixels to be used for residual stress evaluation can affect the final quality of the measurement.
Title of the Paper: Fracture Behaviour of Hot-Pressed Glass Ceramic Dental Crowns
Authors: Liliana Porojan, Sorin Porojan, Anghel Cernescu, Cristina Savencu
Pages: 266-269
Abstract: New ceramic materials, like hot-pressed glass ceramics can be used to achieve monolithic full anatomic all-ceramic dental restorations even in the molar areas. Due to the fact that these materials are brittle and susceptible to fracture, the aim of the study was to reveal the fracture behaviour of hot-pressed glass ceramic molar crowns under different loading methods. For the experimental analyses anatomically first upper molar crowns were fabricated. The specimens were submitted to cyclic fatigue loading and fracture resistance testing. The mode of failure depends on the loading mode. Static loading, wide used in literature, can give an information regarding the values of fracture resistance, but are not illustrative for the long-term success of the restorations, like fatigue behaviour. The most accurate way to simulate the clinical behaviour is the cyclic loading in order to simulate a defined period of oral service. In vitro testing is important before the clinical application.
Title of the Paper: Palmprint Identification Using Discriminative Frequency Components and Extreme Learning Machine
Authors: Burhan Ergen, Vedat Tümen
Pages: 262-265
Abstract: This paper proposes a novel fusion method for palmprint identification based on frequency component analysis, autoregressive signal modeling and extreme learning machines. After determining frequency components by means of a two dimensional Fourier Transform (2DFT), the components are evaluated in three parts; imaginary, real, and absolute values. The 2D components are converted 1D signal using spiral scanning scheme. Then, autoregressive (AR) signal modeling is used to find out dominant components that they are the input for extreme learning machines (ELM) based classifier. This scheme is applied for each part of the frequency component. Experimental result on reliable well known PolyU palmprint database shows the effectiveness of the proposed method with %95 correct recognition rate.
Title of the Paper: Data Quality Metrics for Data Entry Time Quality Evaluation
Authors: Kyung Mi Lee, Keon Myung Lee
Pages: 258-261
Abstract: Acquisition of quality data is crucial in data analysis, machine learning and data mining. Once poor quality data have been admitted into the database, it is costly to detect and remove. One of best practices is to prevent such poor data from being admitted to the system. This paper is concerned with a data entry framework and quality metrics which evaluate newly issued data on their quality. An automatic data entry framework to evaluate incoming data and to detect suspected attribute values enables the data entry personnel to reevaluate or check suspicious data at their entry stage. The proposed framework with integrity metrics has been applied to a cohort data collection system and it has shown the promising results.
Title of the Paper: Learning Management System (LMS) Technical Training Necessary but not Sufficient
Authors: Solomon Negash, Peter N. Meso, Tamara Powell
Pages: 254-257
Abstract: This research is an exploratory study to develop research models to understand the impact of technical and pedagogical LMS training. We develop a research instrument, validate it through empirical study, and propose a model delineating technical and pedagogical LMS training impact. The LMS market is projected to reach $7.8 billion in 2018; it has been growing at a 25% annual rate since 2013. Despite the fast adoption, about 25% of LMS users report dissatisfaction with the technology. Many faculty members undergo LMS training to assist them in using the software more effectively. Most of this training focuses on imparting technical competencies pertaining to features, functions, and navigational capabilities of the LMS with little thought to higher level outcomes such as designing or developing LMS-based assignments that foster critical thinking. This exploratory research found training on features, functions, and navigation as necessary but not sufficient to assist faculty in teaching effectively using the LMS. Technical training is found to achieve only first level outcomes like trainee satisfaction and self-competence. The study finds that LMS pedagogical training produces higher level (second level) outcomes that impact student engagement and innovative use of the LMS by instructors. We provide empirical evidence from our pilot study with a proposed theoretical model to increase second-level outcomes.

Title of the Paper: Vision-Based Mobile Robot Localisation and Mapping System with Kinect
Authors: László Somlyai, Zoltán Vámossy
Pages: 241-246
Abstract: RGBD cameras are increasingly used for mobile robot developments recently. Data of the sensor can be used for creating maps during the navigation and localization made on this. The robot system described in the article is able to create a map in an unknown environment during its navigation and localize its state on it parallel. The system was placed on a modified RC robot car. The process is able to evaluate movement of the vehicle in real time using data from the Kinect sensor placed on the robot and it continuously updates this map using new information. Pictures made by the camera during movement of the system are overlapped with each other. Evaluation of movement is based on join cohesive feature point pairs in each three dimensional point clouds. Definition of transformation between cohesive three dimensional feature points is based on an SVD algorithm. During a multistage iteration, the system minimizes the join fault and deletes point pairs detected wrong.
Title of the Paper: The Holonic Approach for Controlling Modern District Heating and Cooling Systems
Authors: Lubomir Vasek, Viliam Dolinay, Vladimir Vasek
Pages: 233-240
Abstract: This article presents the idea of distributed control methods for district heating and cooling system control. The modern concepts of distributed control are also represented by multi-agent and holonic systems that are also in this article described and compared. Up to date district heating systems integrate (are preparing to be able to integrate) many elements, such as small heat source for example in the form of renewable energy, storage tanks, surpluses form active buildings and many other. The concept of clustering of these disparate elements and their interconnection is referred as Smart Thermal Grid. This concept is analogous to the Smart Grid, which has been applied for many years in the production and distribution of electric power. Smart Thermal Grid concepts also cannot be isolated from existing concept, because heat and power production is often strongly interconnected. Effective use of all the elements forming such extensive system also requires new approaches in control. The central approach is already insufficient and the intention is to enforce already mentioned distributed concepts. This article will mainly focus on two distributed approaches - multiagent and holonic. These approaches are similar in many aspects, but still there are some differences and these will be discussed.
Title of the Paper: Cascaded Wavelength Converters Using Multiple Pumping Signals, Covering All-Optical (C-L) Bands and Achieving a Remarkable Bit-Error Rate
Authors: Mohamed I. Shehata, Osama A. Omer
Pages: 222-232
Abstract: The aim of this work is to demonstrate the efficiency of a cascaded wavelength conversion by four-wave mixing technique in a commercial traveling wave semiconductor optical amplifier. A scheme of multiple cascaded wavelength converters spanning of 400 km for single-mode fibers is suggested. The proposed scheme differs from the conventional schemes as utilizing cascaded two commercial TW-SOA for each wavelength converter stage rather than using only one SOA in addition to Erbium-doped fiber amplifier (EDFA). This scheme overcomes the main problem appeared in the conventional schemes that suffer from the amplified spontaneous emission which considered as a noise that degrades optical signal to noise ratio of the converted signal. Based on the simulation results, bit-error-rate performance near 10-13 at 40 Gbit/s is achieved for five conversions up to 95 nm as a conversion range, covering C-L optical bands. A power penalty of 10.06 dB with a remarkable conversion efficiency of 98% (i.e. approximately free-error) is measured for overall system.

Pages: 217-221
Abstract: The paper descries the design of the electrocapacitive measuring transducer used to implement electricalcapacitive method to perform in-process measuring the single-core electric wire capacitance per unit length during its manufacturing. The ECMT optimal design parameters were chosen based on computer simulation of the interaction of the ECMT electric field with the wire using COMSOL Multiphysics. The block diagram of the device CAP-10 developed for implementation of the proposed method is presented. Physical configuration of the CAP-10 is shown, and its operating principle is described. An algorithm for conversion of the ECMT measuring signal that implements the technique of offsetting from the impact of changes in water conductivity on the control results is proposed.
Title of the Paper: Persistent and Reliable Flash-Based Data Container for Embedded Systems
Authors: Michal Bližnák, Tomáš Dulík, Tomáš Jurena, Peter Janku
Pages: 211-216
Abstract: NOR-FLASH memories often available as an integral part of modern MCUs and SoC microprocessors can be used as an ideal storage container for persistent application data in embedded systems design. Unfortunately, a technological background of these memory chips avoids users from simple and efficient multiple writes into identical memory locations which is very common use case scenario when, for example, the application’s configuration is updated. This paper introduces simple and elegant solution including its reference software implementation which allow users to write configuration data structures into the FLASH RAM in highly efficient and reliable way. Discussed approach minimizes number of needed write and erase cycles and maximizes reliability of the overall write process.

Authors: Mirko Novák, Josef Faber, Petr Bouchner, Stanislav Novotný, Alina Mashko
Pages: 205-210
Abstract: Individual human behavior makes a significant impact to the road and traffic safety. The necessity of minimizing the human factor influence is rather obvious. A detailed study of different aspects of human-machine interaction shall make it possible to determine reasons of faulty human behavior and develop methods for its prevention. Complex approach for problem solution is suggested. A truck simulator laboratory described in this article shall suggest wide range of possibilities for the relevant research. Observation of various aspects of faulty driver behavior using different methods, namely combination of brain activity observations (EEG) together with data obtained from readings of other tools such as ocular movements, heartbeat, mimics, muscular activity, gestures, driving behavior and vehicle behavior is to be run for data collection and its further analysis. A set of pilot experiments has been relevant research of both electroencephalographic (EEG) and near infra-red (NIRS) signals analysis of drivers, exposed to influence of various kinds of attention load on adaptive driving simulator is presented. The results are expected to be a basis for recommendation for further deeper and wide scale analyses of various load influences on driver brain.

Pages: 195-204
Abstract: The medium of computer and video games are being studied profusely in a wide array of research. Constraint databases and video games have been around for a long time, but they have never been combined together before. In this paper, we describe the A-Maze-D system, which shows that constraint databases can be applied conveniently and efficiently to the design of maze games. A-Maze-D provides a versatile set of features by the combination of MATLAB scripts and the MLPQ constraint database system. A-Maze-D enables an efficient implementation of many complex features existing in games such as collision and hindering vision. A-Maze-D is the first system that uses constraint databases to build maze games and opens new ideas in video game development.
Title of the Paper: GPGPU Accelerated Large Scale 3D Object Reconstruction Application for Fixed and Rotary Wing Unmanned Aerial Vehicles
Authors: András Molnár, Dániel Stojcsics
Pages: 189-194
Abstract: GPGPU (general-purpose computing on graphics processing unit) cards compared to a standard CPU (central processor unit) has many times more cores. The advantage of this technology is the possibility of using multiple GPGPU cards in a single PC making the parallelization opportunity to a next level. Large scale 3D object reconstructions usually made by human piloted airplanes with massive sensor arrays (high resolution RGB camera or camera array, LiDAR or laser scanner). With the advance of small size fixed or rotary wing unmanned aerial vehicles (UAVs) and a relatively cheap camera this procedure can be made with much less effort. No need for using public airports, airspace and human piloted expensive aircrafts. UAV operator can make the measurements within a few hundred meters from the desired object. Using GPGPU accelerated photogrammetry methods large scale 3D object reconstruction can be made from zero to 3cm/pixel resolution 3D reconstructed and textured object within hours. The paper presents the procedure step by step, showing the technology critical parts of the method.

Title of the Paper: An Application of Kano Method in the Elicitation of Stakeholder Satisfying Requirements for an e-Ebola Awareness System
Authors: Azham Hussain, Emmanuel O. C. Mkpojiogu
Pages: 169-178
Abstract: Several software requirements elicitation techniques exist and are used in the elicitation of software requirements. However, most of the techniques are limited in that they are only effective in capturing the voice of the customer/user. They are not effective in capturing their mind. There are some kinds of requirements that stakeholders take for granted, not expecting or are not apt to voice out. Such requirements need special requirements elicitation approaches that will probe the psychology of the respondents so as to succinctly collect the needed requirements from them were necessary. Kano model provides a framework that enables the elicitation of these kinds of requirements. More so, it allows appropriate requirements to be elicited that will lead to the satisfaction of stakeholders if the requirements are met or to their dissatisfaction if they are unmet. It categorizes software requirements based on some quality attributes that describes the kind of requirements elicited. The Kano approach also, helps to obtain the perceived quality of the proposed product from the customer/users’ point of view. This method helps to filter out requirements that do not lead to the satisfaction of stakeholders and thus the quality of elicited requirements and the proposed software solution. Kano method, though popular in the interdisciplinary field of quality management, is seldom applied in the field of software engineering, especially in requirements elicitation. In this study, the Kano method was applied in the elicitation of requirements for a proposed e-Ebola Awareness System. The result of the Kano analysis indicated that the elicitation of stakeholders’ satisfying requirements leads to increase in the satisfaction level of potential users/customers of the would-be product. It also indicated improvement in the perceived quality of such product from the viewpoint of the potential users/customers as shown from the customer satisfaction coefficients and the self-stated importance ratings.

Title of the Paper: Rising from Ruins: from Derelict Spaces to Sustainable Landscapes – the Portuguese Case
Authors: Luís Loures, Frederico Meireles, Laura Costa, Ana Loures
Pages: 156-161
Abstract: The legacy of derelict, obsolete, and often abandoned post-industrial structures and sites we face today in our landscapes is, arguably the result of human current and former uses of land. One way or another, the present situation, enabled by technological innovation and structural economic change, is founded in human (ab)use of limited and valuable resource, and on his increasing ability to affect large landscapes. Though it is widely recognized that the reclamation of post-industrial landscapes constitutes an important strategy towards city development, it is normally acknowledged that redevelopment projects are generally associated to multidimensional objectives based somehow on a twist of sociocultural, economic and environmental issues. By assessing a set of 18 redevelopment proposals/projects where it is possible to identify the relevance of each of them to the different sustainability dimensions and therefore to urban development, this paper aims to point out the relevance of these projects to achieve sustainable urban environments considering the aforementioned levels. The analyses of the case studies presented in this article enabled us to conclude that even if post-industrial landscapes are commonly experienced negatively, as fragmented and incoherent because it is difficult to conceive a legible whole, the redevelopment of post-industrial facilities may enable a sense of spatial enlargement, with high degree of complexity and with diverse ecological and social benefits, contributing to local redevelopment, reason why they should be viewed as a resource and its recovery as an opportunity.
Title of the Paper: Multispectral Data-Fusion and Mapping for Reconnaissance Robotics
Authors: Petra Kocmanova, Ludek Zalud, Frantisek Burian
Pages: 145-155
Abstract: The paper deals with calibration of multispectral vision systems, evaluation of the calibration and data-fusion quality in both laboratory and real-world conditions and appropriate use of these techniques for multispectral measurement in telepresence and digital 3D mapping. Two objects for multispectral calibration and fusion evaluation are described. The objects were used by our team for calibration and evaluation of advanced visual system of Orpheus-X4 robot that is taken as a demonstrator, but their use is much wider and we suggest to use them as testbed for visual and optical measurement systems of mobile robots. The multispectral fusion is used for two main purposes – real-time display to operator, e.g. through visual telepresence, or for autonomous building of spatial maps of the robot’s environment. Several aspects regarding proper use of the technique for telepresence are described. Mapping system developed by our team working with multiple robots with different features is described. Several evaluation experiments related to the fusion/calibration and mapping were done and are presented in the paper. We provide the calibration software as publicly available, including source code. Our team also provides testing data for both the calibration/evaluation and mapping.
Title of the Paper: An approach in the classification of automation levels for multi-cargo ports.
Authors: Aureo Emanuel Pasqualeto Figueiredo, Sérgio Hoeflich, Leticia Figueiredo, Ricardo De Deus Carvalhal, Sergio Luiz Pereira, Eduardo Mario Dias
Pages: 137-144
Abstract: The current trend of cargo handling in ports is to use increasingly specialized terminals that allow systematizing processes by applying massive automation devices. The state-of-the-art in port automation is largely automated terminals where human presence in the yard is restricted to overseeing the processes. However, considering the existence of century-old port activity, there are important installed ports that handle different types of cargo, mainly grouped as CT-Container, DB- Dry Bulk, GC-General Cargo, LB-Liquid Bulk, using different standards of operation and safety protocols that require new practices using of specific mechanization and automation.

Authors: Pasquale Colonna, Paolo Intini, Nicola Berloco, Filomena Mauriello, Antonio Perruccio, Vittorio Ranieri
Pages: 117-126
Abstract: A data set composed by repeated speed measurements belonging to an on-road experiment was inquired into this study by using the regression tree and the ANOVA mixed model techniques. The on-road experiment consisted in the repetition of a driving test six times in six different days for a sample of 20 drivers on a rural road in the province of Bari, Italy. In order to explain the changes in the response variable speed, the drivers’ behavioral differences, the road geometry (in terms of sight distance) and the time (in terms of the six days of testing) were used as variables. All the three chosen variables are responsible for improvements in the tree growing and they have significant effects on speed according to the mixed one-way ANOVA. Some considerations about the results of the two analyses were given in this paper, together with an analysis of the interactions between the variables based on them. In more detail, some interesting differences between the behavior of aggressive drivers and the behavior of prudent drivers were highlighted.
Title of the Paper: Everyware Everywhere: Overview of the Social Implications of Embedded Systems, Internet and Mobile Technologies
Authors: Nikola Vlahovic, Jovana Zoroja, Vesna Bosilj Vuksic
Pages: 106-116
Abstract: Embedded systems are widely implemented in every aspect of contemporary societies. The scale of usage of embedded systems in everyday lives is so high that people have become so accustomed to the conveniences they provide that they become unaware of their existence. Nevertheless, business processes and procedures, interaction with government institutions and public administration as well as social contacts have dramatically changed due to the implementation of embedded systems. The goal of the paper is to present changes in contemporary societies that are influenced by the intense use of embedded systems. Current trends in mobile computing and RFID technologies are two main driving forces of embedded systems that will be considered in this paper, as well as the development of web semantics and intelligent agents that characterize the era of Web 2.0 and upcoming era of Web 3.0. The paper will try to analyze and discuss possible interactions and amalgamation of these embedded systems as well as possibilities they may bring in the digital or e-societies in future decades. A survey will be presented in order to determine user perception of these technologies and estimate potential users interest in the adoption of future services that will become available in the next decade.

Authors: Costin A. Boiangiu, Adrian C. Firculescu, Nicolae Cretu
Pages: 97-105
Abstract: The engineering education is facing a demand for a change in the current teaching approach that would satisfy the needs of employers and face the constantly changing professional requirements. The current paper aims to analyze two common teaching approaches that are frequently used among learning academics, the collaborative and the independent teaching approaches and compare the results with other learning techniques that were addressed in previous academic years of teaching the Software Project Management course at the "Politehnica" University of Bucharest for students in their senior year of studying Computer Science and Engineering. Considering the results gathered from the experience with the two aforementioned approaches, we developed a "mixed" learning method, combining elements from both forenamed learning techniques as one anarchic-style teaching method, which is also described.
Title of the Paper: Proposal of a New Method to Analyze the Road Safety Conditions Related to Friction
Authors: P. Colonna, A. Perruccio, N. Berloco, P. Intini, V. Ranieri
Pages: 87-96
Abstract: This paper represents a new method to analyze the problem of friction of road vehicles. Starting from the 3rd criterion of Lamm, the new concept of “Friction Capital” was introduced as the limit performance of the road in terms of friction. The method has been implemented in a software package called Design Skid Resistance (DSR), which reliability is tested providing the reconstruction of eight real skidding accidents. The output of the DSR is the Friction Diagram that represents the percentage of “Friction Capital” that a vehicle is using traveling on a given road. This percentage is defined as FUSED. During the design step, the Friction Diagram could be used in order to quantify the risk of skidding related to a given road layout. In this paper, the authors provide an example of DSR application to an Italian rural road, and investigate the influence of the vehicle type on the Friction Diagram, since it was observed that the type of vehicle used in analyzing a road segment makes the values of FUSED change when the boundary conditions and the road geometry change.

Title of the Paper: The Study of Ground of Divorce Under the Civil and Commercial Code that Affects Quality of Life
Authors: Kamonwan Yoowattana
Pages: 1-4
Abstract: Marriage is legal and acceptable way to create family and lead to the legal status of man and woman referring to husband and wife. Some regards family as vital fundamental background which partly influences human behavior in either good or bad toward society. Consequently, when problems arise in family, it affects society as well. Divorce, therefore, is the final method to end problems (relationship) if there is no other way to compromise. In some countries, divorce is not an available choice due to religion restriction. In Thailand, however, divorces can be categorized in 2 cases which are divorce by mutual consent and divorce by judgment of the Court. The latter case refers to the case that either husband or wife do not agree to the divorce or cannot live together as a couple. Based on Thai law, husband or wife can exercise his/her right to divorce according to section 1516 (ground of divorce). This research aimed to indicated conditions and objectives relating to ground of divorces due to willfully separation either by husband or wife over 1 year according to section 1516 Thai Civil and Commercial Code. If the fact appears that husband and wife agree not to cohabit as husband and wife by ending their sexual relationship but still live together in the same area though in different household, by law, this show no intention of separation. Such action does not consider as a separation divorce ground. Moreover, the fact that period of separation hold only one year is unreasonable and does not suit present situation. Researcher, thus, intend to conduct this research in order to study cause of action regarding separation divorce ground and period of separation leading to justified law enforcement.
