Dear Reader, it is our pleasure to present to you Position Papers of the 2013 Federated Conference on Computer Science and Information Systems (FedCSIS), which took place in Kraków, Poland, on September 8–11, 2013. This is the first year when position papers have been introduced as a separate category of contributions. This decision was grounded in the observation that, with decreasing acceptance rate of full papers (this year approximately 43%), a number of valuable contributions have to be rejected. They often represent initial stages of interesting projects, descriptions of industrial applications, etc. Therefore, in order to not to lose interesting contributions, this volume was created.
FedCSIS was organized by the Polish Information Processing Society (Mazowsze Chapter), AGH University of Mining and Metalurgy, Wrocław University of Economics and Systems Research Institute Polish Academy of Sciences. FedCSIS was organized in technical cooperation with: IEEE Region 8, Computer Society Chapter Poland, Gdańsk Computer Society Chapter, Poland, Polish Chapter of the IEEE Computational Intelligence Society (CIS), ACM Special Interest Group on Applied Computing, Łódź ACM Chapter, SERSC: Science & Engineering Research Support soCiety, Informatics Europe, Asociación de Técnicos de Informática, Committee of the Computer Science of the Polish Academy of Sciences, The Polish Association for Information Systems, Polish Society for Business Informatics and Polish Chamber of Commerce for High Technology.

Computer Aided Material Selection in Design Process 451Decision Support SystemsMarcin Jaromin, pages 3 – 7. Show abstractAbstract. The selection of proper materials for different components is one of the most challenging tasks in engineer’s activity. The traditional approach to the selection of materials required looking through the literature and material safty data sheets.With the development of information technology, engineering work has also changed. It involves not only arduous browsing catalogues and guides but also defining queries in database applications. This approach greatly accelerated the process of selection of materials, but it did not eliminate all the problems associated with obtaining information from large data sets. This paper presents the developed Web Material Selector application designed for computer-aided materials selection. The WMS allows to work with very large databases through the use of a professional tool to manage complex data structures. At the same time the application is designed to optimize the search process, what significantly reduces the number of materials whose properties a designer should carefully consider.

Finer Investigation into Role 441Riichiro Mizoguchi, Kouji Kozaki, Yoshinobu Kitamura, pages 11 – 18. Show abstractAbstract. This paper discusses three issues about role: (1)
continuity of role playing in the case of role change, (2) role as
specification and (3) vacant role. As to (1) we introduce
decomposition of a role into two subroles: post subrole and
constituent subrole. The latter is crucial for coping with the
issue of continuity. The idea of role as a specification is
proposed after detailed discussion about what a role should be.
Finally, the third issue is addressed by introducing a new idea
of virtual player to harmonize all the new ideas proposed in this
paper. A preliminary result of formalization of the new theory is

Parallel algorithms for adaptive time-stepping in radiofrequency liver ablation simulation: implementation on an IBM Blue Gene/P computer 456K. Georgiev, N. Kosturski, S. Margenov, Y. Vutov, pages 23 – 26. Show abstractAbstract. This work concerns the mathematical modeling and computer simulations of the heat transfer process. The core is solving the time-dependent partial differential equation of parabolic type. Instead of a uniform discretization of the considered time interval, an adaptive time-stepping procedure is applied in an effort to decrease the simulation time. The procedure is based on the local comparison of the Crank Nicholson and backward Euler approximations. Computer simulation on geometry obtained from a magnetic resonance imaging (MRI) scan of the patient is performed. Results of some preliminary numerical experiments performed on a selected test problems are presented and discussed
Performance Evaluation of MPI/OpenMP Algorithm for 3D Time Dependent Problems 460Ivan Lirkov, Marcin Paprzycki, Maria Ganzha, Paweł Gepner, pages 27 – 32. Show abstractAbstract. We consider the 3D time dependent Stokes equation on a finite time
interval and on a uniform rectangular mesh, approached in terms of
velocity and pressure. In a parallel algorithm, based on a novel
direction splitting approach, the pressure equation is derived from a
perturbed form of the continuity equation, in which the
incompressibility constraint is penalized in a negative norm induced
by the direction splitting.
In order to achieve good parallel performance, the solution of the Poison problem for the pressure correction is replaced by solving a sequence of one-dimensional second order
elliptic boundary value problems in each spatial direction. The
parallel code was developed using MPI and OpenMP and tested on modern
computer systems. The performed tests illustrate the
parallel efficiency, and the scalability, of the direction-splitting

Full 3D Robotic Arm Control with Stereo Cameras Made in LabVIEW 52Automatic Control and Robotics, Computational Intelligence, Image Processing and Computer Animation, Machine Learning ., Pattern Recognition, Software EngineeringRoland Szabó, Aurel Gontean, pages 37 – 42. Show abstractAbstract. In this paper we shall present a full application made in LabVIEW, which can control a robotic arm. The control is made upon image recognition system. The image recognition library is the NI Vision Development Module, which has all the tools necessary to create industrial computer vision applications. LabVIEW was also a good choice, because it has integrated a lot of interface drivers. We used the VISA (Virtual Instrument Software Architecture) driver for controlling the robotic arm on the RS-232 interface. We also have a very friendly GUI (Graphical User Interface) and a very friendly graphical programming environment. Our algorithm is to detect certain key parts of the robotic arm, then unite tem with straight lines, create the robotic arm’s skeleton and introduce the data in the PC. After this, with some mathematical calculations we can compute exactly the angles needed to be moved by each motor to move the robotic arm in the desired point in the space. The joints of the robotic arms are detected with color recognition algorithm. We placed colored bottle stopper over each joint that interested us and recognized it with color filtering, this way we had extracted from the capered image that key points which we needed.

USSD communication channel as alternative to XML SOAP in mobile Unified Communication applications 172Dariusz Bogusz, Grzegorz Siewruk, Jarosław Legierski, Jan S. Kunicki, pages 45 – 50. Show abstractAbstract. Traditional mobile Unified Communications (UC) clients use data channel over GSM/UMTS network for communication with UC services broker and providers. UC signaling traffic characteristics require large number of short data connection sessions and can cause overload of mobile network. The reason is ratio of overhead data to the useful signaling information. This paper presents analysis of mobile UC architectures and possible use of Unstructured Supplementary Service Data (USSD) channel for UC application in mobile domain. The usage of USSD channel can help to provide more effective applications for mobile UC user.

A Middleware Architecture for Mobile Social Networking with Intelligent Energy Saving 73Mobile applications, Network-based computing systems, Wireless communicationsLuiz Marcus Monteiro de Almeida Santos, Maria Augusta Silveira Netto Nunes, Admilson de Ribamar Lima Ribeiro, pages 57 – 62. Show abstractAbstract. In recent years, middleware for social mobile networking has attracted the attention of academia, causing the design and development of various approaches by researchers. This type of middleware facilitates and makes more efficient the development process of mobile social networking applications. Furthermore, middleware solutions also abstract the communication process with other applications, allowing the acquisition, persistence and reuse of social context information and location of users, besides providing an API so that developers can access this information quickly and build new social applications. With a view to supporting this new trend of research, in this paper we propose a middleware architecture for mobile social networking called My-Direct which will make use of Wi-Fi Direct as a solution to improve the connectivity between the nodes of the social network. Along with My-Direct also created an intelligent mechanism for the management of mobile resources in order to reduce energy consumption.

Resources placement in the 4-dimensional fault-tolerant hypercube processors network 259Architectures, Protocols and Algorithms of Sensor Network, Performance, Simulation and Modeling of Sensor Network, Resource Allocation, Services, QoS and Fault Tolerance in Sensor NetworksJan Chudzikiewicz, Zbigniew Zieliński, pages 69 – 74. Show abstractAbstract. In the paper some properties of the perfect resources placement in the 4 dimensional hypercube network with soft degradation are considered. The methods of determining some kind of perfect placement are discussed. Two algorithms for the resources deployment are proposed. Moreover, some characteristics of the network degradation are determined. The average number of processors working of degraded network with given order for a specific type of resource placement is determined. This value characterizes the loss of the network computing capabilities resulting from the increase of the degree of network degradation. Also, the probability distribution that for degraded logical structures of the hypercube with given order there exists a specific type of resources placement is evaluated.

Wireless Sensor Network Based Soil Moisture Monitoring System Design 175Applications of WSN, Sensor Circuits and Sensor DevicesWen-Yaw Chung, Jocelyn F. Villaverde, Janine Tan, pages 79 – 82. Show abstractAbstract. Soil moisture is the amount of water in the soil. It plays a crucial role for efficient photosynthesis, respiration, transpiration and transportation of minerals and other nutrients through the plant. Proper irrigation schedule is very critical to plant growth. This paper presents a soil moisture monitoring system which comprises of commercially available soil moisture sensor Decagon EC-5, low power nRF24L01 wireless transceiver, and MPC82G516A microcontroller. The sensed soil moisture content from the EC-5 sensor node will be transmitted to the coordinator via 2.5GHZ wireless signal. The coordinator will transmit the data to the computer using RS232 interface. The key components used in the proposed system are low cost and more flexible. The locally developed MPC82G516A microcontroller consumes low power due to its 1-T instruction time. In addition, the EC-5 sensing electrode also has advantages of easy installation and replacement in the farm. The developed system provides a better data transmitted and processed wirelessly and it can serve as a basis for efficient irrigation scheduling.

An examination of students’ attitudes and preparedness for the introduction of ICT-enabled learning at university 459Colin Hales, Barbara Fura, pages 99 – 104. Show abstractAbstract. The article presents research results relating to the attitudes of students’ towards a wider use of ICT in the education process (e-learning/blended learning). The analyses were conducted against the backdrop of the students’ subjective assessment of their general computer aptitude as well as their access to and use of ICT. Results prove that students’ opinions on the wider use of ICT in the learning process was influenced by a subjective assessment of their general computer skills. That level was in turn determined by factors including study specialization as well as socio-demographic characteristics of the respondents, such as gender, place of residence and age. Access to a computer/Internet had some influence upon familiarity with given applications and online activities. Research results confirm the presumption that students with a higher appraisal of their competence were more positively inclined towards a wider use of ICT than those with lower levels of competence.
IaaS Cloud Model for e-Ordering and e-Invoicing 323Cloud computing, SOA, Web services, Enterprise information systems (ERP, CRM, SCM, etc.)Kiril Kiroski, Marjan Gusev, Sasko Ristov, pages 105 – 110. Show abstractAbstract. This paper addresses the modeling of an IaaS cloud e-Ordering and e-Invoicing solution.
We have faced several challenges in the process of migration of the existing web application on the cloud, such as the reorganization of the proposed non-cloud model and definition of the software modules that can communicate in a dynamic environment with various number of virtual machines.
In the design process we have classified two kinds of software modules: static and dynamic. The classification is based on the level of required elasticity and scalability, as well as the activity that is associated with the corresponding module (tool). To finalize implementation of this idea, we have developed indicators to determine the required conditions for activating additional cloud resources, or deactivating involved resources.
The result of this design process is a new cost effective solution with increased availability and performance compared to the non-cloud model.
We have also recognized the advantages and disadvantages of such cloud solution, and discussed the characteristics that make our approach unique.
A Declarative Approach to Cost Estimation in Multi-Project Environment 94Business Intelligence methods and tools, Concepts and methods of business informatics, Decision Support Systems and data mining, IT projects & IT projects management, Knowledge-based and intelligent systems in management, Management Information Systems (MIS), Strategies and methodologies of IT implementationMarcin Relich, pages 111 – 116. Show abstractAbstract. The paper aims to present a cost evaluation for multi-project environment, taking into account imprecision in activity duration and cost. Data specification in the form of discrete α-cuts enables the connection of distinct and imprecise data, and the implementation of a constraints satisfaction problem with the use of constraint programming. Moreover, using α-cuts, optimistic, pessimistic, and several intermediate scenarios concerning the project scheduling and cost can be obtained and considered in terms of different risk levels. Each scenario can be assessed according to criteria such as time, cost, and risk level. A declarative form of the description of a multi-criteria decision problem allows its implementation in constraint programming languages and facilitates the development of a decision support system. The proposed methodology can be easily incorporated into available fuzzy project scheduling software to provide a better perception of risk that is usually obscured in the conventional approach.

Modelling Information Systems by Document Flow Description 454Domain-specific languages, Formal semantics and syntax, Language concepts, design and implementation, Metamodeling and modeling languages, Model-driven engineering languages and systems, Program generation and transformationVladimir Ivančević, Marko Knežević, Ivan Luković, Verislav Đukić, pages 121 – 126. Show abstractAbstract. In this position paper, we argue in favour of three points related to document-centric modelling of information systems: (i) information systems of some organizations may be understood in terms of documents, actions, actors, and document flow; (ii) modelling document flow may be a central step in modelling an information system; and (iii) as an approach to information system modelling, document flow modelling may be coupled with the form-based approach to information system development that is featured in IIS*Case, a model-driven development tool, because the form concept is semantically close to the document concept. With respect to these claims, we formulate a document-centric and model-driven approach to information system development, explain its particularities, and present a plan of activities that should lead to its implementation. By relying on domain-specific languages, the proposed approach should allow generation of information systems supporting document manipulation within a document flow and process mining.
