    Molecular beam epitaxially grown fullerene layers are investigated with the help of image processing. The layered structures are studied in morphological respect. The individual layer morphologies are derived from the atomic force microscopy picture of the surface. The pattern morphology of the certain layers is analysed by box counting method. The surface morphology shows fractal behaviour. The pattern of each layer shows different dimension. The actual dimension depends on the actual distance of the layer from the substrate. The change of the dimension is attributed to the change of the binding behaviour. The topology of the surface is also studied using participation ratio and structural entropy calculations.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (680 KB) |  | HTML iconHTML  

    In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a vector network analyzer E5071B and adaptation test fixture on PCB board. Since the behavior of the component depends on the environment where the component is placed, measurement results strongly depend on the choice of the PCB. Two new adaptation test fixtures in PCB technology on different board type are presented. The equivalent circuit parameters are extracted in closed form, from an accurate measurement of the board-mounted SMD inductor S-parameters. The extraction of parameters (intrinsic and extrinsic) of SMD inductor is shown. View full abstract»

    The paper deals with the wireless sensor-based remote control of mobile robots motion in an unknown environment with obstacles using the Bluetooth wireless transmission and Sun SPOT technology. The Sun SPOT is designed to be a flexible development platform, capable of hosting widely differing application modules. Web technologies are changing the education in robotics. A feature of remote control laboratories is that users can interact with real mobile robot motion processes through the Internet. Motion control of mobile robots is very important research field today, because mobile robots are a interesting subject both in scientific research and practical applications. In this paper the object of the remote control is the Boe-Bot mobile robot from Parallax. This Boe-Bot mobile robot is the simplest, low-cost platform and the most suitable for the small-sized, light, battery-driven autonomous vehicle. The vehicle has two driving wheels and the angular velocities of the two wheels are independently controlled. When the vehicle is moving towards the target in an unknown environment with obstacles, an avoiding strategy is necessary. A remote control program has been implemented. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (182 KB) |  | HTML iconHTML  

    In this paper we show a new method for reconstructing binary matrices. We focus on the reconstruction of hv-convex matrices. We show that our algorithm finds all the solutions, and sort out the ones that do not comply to the hv-convex criteria. We also show that this algorithm works best for smaller matrices up to size 20times20 pixels. We make some notes on the possible speed-up strategies too. View full abstract»

    As with many large organisations, EU recognises the advantages that being able to work in a standard way brings. EU and NATO nations will use a Logistic Information Management (LIM) concept that couples available information technology with logistic processes and practices. The Logistic Information Management will focus on identifying logistic information requirements that meet the EU nation's needs. Implementation of this concept should reduce management and support costs, the logistic footprint and logistic support delivery time. It should also enhance the efficiency and effectiveness of multinational logistic support. View full abstract»

  • A concept of universal integral based on measures of level sets

    Page(s): 11 - 16
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (122 KB) |  | HTML iconHTML  

    For functions with values in the nonnegative real numbers, universal integrals are introduced and investigated which can be defined on arbitrary measurable spaces and for arbitrary monotone measures, including as special cases Choquet and Sugeno integrals. For a fixed pseudo-multiplication on the nonnegative real numbers, the smallest and the greatest universal integrals are given. Finally, another construction method for obtaining universal integrals is introduced. View full abstract»

    At SISY 2008 conference we studied the Sugeno, Shilkret and Choquet integrals and some of their level-dependent modifications as TL-(SL-) evaluators. In this contribution we give an overview of possible level-dependent generalizations of Sugeno and Shilkret integrals. We show under which conditions these integrals and their generalizations are T- and/or S-evaluators for an arbitrary t-norm T and t-conorm S. View full abstract»

    There are considered two cases of the real semiring with pseudo-operations: one, when pseudo-operations are defined by monotone and continuous function g (then the pseudo-integral reduces on (g-integral), and the second semiring ([a, b], max, odot), where odot is generated. There are proven generalizations of the Chebyshev's inequality for the both cases of the pseudo-integral. View full abstract»

    Traditionally, the relational algebra uses four groups of operations as follows: the set operations, the selection and projection, the different kinds of the joins, and the rename. There are several operational identities which are very useable in the query optimization processes of database systems. The experience of practical usage of databases has showed that the expansion of the classical relational algebra is required. The new operations are: sorting, grouping, aggregations, extension of the projection, and extension of the join. Several operational identities have been introduced in the expanded relational algebra. Based on this knowledge we are able to growing the effectiveness of the database systems. This is a remarkable retroactivity from the practice to the development of the theory. The paper is devoted to demonstrate the development of the relational algebra springing from the practice.

    Nowadays many companies must adapt their business processes to persistent changes forced by technology, organizational or political factors. Business processes are usually supported by specialized software products. These software products also must adapt to changed business environments. Software users must have effective way to specify new requests for software they use. In this paper is presented model of modified submission phase for software change request process. This model is implemented and verified in ScenarioBuilder, a software used for management of networking scenarios in virtual network laboratory VNLab. VNLab is used for teaching networking concepts at university course. View full abstract»

    Modern organizations and companies exist in time of progressiveness in almost all segments of life and work influenced by large, rapid and dynamic changes. In such conditions, business world is enforced to adapt to these changes. Character of resulting changes is such that leads to question the existing social theories, especially in the macroeconomic field. Project management is a new and specialized management discipline. The main goal of project management is an efficient project realization within the planned time and planned costs in the conditions of significant external and internal changes. In this paper we developed a fuzzy reasoning approach for a Postal company restructuring project management. We combined Fuzzy PERT method with Fuzzy Delphi for activity time forecasting and finding the critical path. This approach has been applied on a project of Serbian postal company restructuring and obtained results appeared as very consistent. View full abstract»
