International Conference on Mixed Design of Integrated Circuits and Systems (MIXDES)

作者： Mateusz Baszczyk Piotr Dorosz Sebastian Głąb Wojciech Kucewicz Łukasz Mik Maria Sapor Faculty of Electrical Engineering Automatics Computer Science and Electronics Department of Electronics AGH University of Science and Technology Krakow Poland

This paper presents the method for the compensation of the temperature fluctuations in the measurement system based on the Silicon Photomultipliers. The system was created by the authors of the paper. Temperature has very strong influence on the gain of the detectors. Because single photons are detected and the system is very sensitive, its parameters has to be steady during the measurements. Temperature is being stabilized by changeable bias voltage of the detector. This paper describes how the algorithm of compensation has been determined during series of measurements and calculations.

International Conference on System Theory, Control, and Computing (ICSTCC)

作者： Cosmin Adomnicăi Viorel Mînzu Automatics Computer science Electrical and Electronic Engineering Faculty Dunãrea de Jos Galati University Galati Romania

In this paper we present a method of transmitting routing updates in IPv6 networks. Routing protocols that use discrete packets to send/receive routing updates are susceptible to instability in a limited bandwidth or lossy links environment. We study and compare our method with OSPF and EIGRP and show that it stabilizes more rapidly. By design, our method is robust and it is not susceptible to bandwidth limitation and to the degree of lost packets like other routing protocols.

Procedia computer Science 2012年 9卷 206-215页

作者： Dariusz Krol Bartosz Kryza Michal Wrzeszcz Lukasz Dutka Jacek Kitowski AGH University of Science and Technology ACC Cyfronet AGH Krakow Poland AGH University of Science and Technology Faculty of Electrical Engineering Automatics Computer Science and Electronics Department of Computer Science Krakow Poland

With the increasing availability of high performance computing power, new possibilities with respect to simulation and analysis become available and feasible. One of such methodologies is data farming, where large amounts of data are generated through simulation of several configurations from large parameter space and then analyzed for patterns. Unfortunately, the availability of versatile data farming systems is very limited and none of existing solutions allows integration with novel Cloud solutions. In this paper, we present our system, which is a flexible solution for running very large Data Farming experiments on both intranet clusters as well as on remote computational resources, including public Clouds. Another important aspect of the presented system is the support of interactive Data Farming experiments with online analysis of partial experiment results and experiment extending capability. Sample application of our system is present on military mission planning support scenario.

Procedia engineering 2012年 47卷 1045-1048页

作者： P. Gwiżdż A. Brudnik K. Zakrzewska Department of Electronics Faculty of Electrical Engineering Automatics Computer Science and Electronics AGH University of Science and Technology 30 Mickiewicza Av. Krakow 30-059 Poland

The aim of this work is to design and test an array of metal oxide gas sensors for reliable and reproducible gas detection. Thermally modulated responses of non-specific, resistive-type metal oxide sensors to various hydrogen concentrations and humidity levels are studied. Temperature of each sensor is controlled and sinusoidal temperature profile is imposed over the temperature range of 200 – 500 °C. The dynamic responses upon hydrogen exposure (0 – 3000 ppm) are recorded and studied. The time of one temperature modulation cycle varies from 5 – 10 minutes.

The following publication is devoted to the mechanisms governing a system which facilitates communication with hearing-impaired people. The key element of the system is an application which translates written Polish texts into the sign language. It uses two complementary databases: the main one consists of a list of lexemes with their characterization, whereas, the latter is a set of grammatical and semantic facts. The message is conveyed in several phases. The core (ideographic) information is complemented by the mimic signs and synthesized speech. The main application joins all the modules and serves as the interface. The authors claim that the system will be helpful in various offices, healthcare centers, schools, etc. © 2012 The authors and IOS Press. All rights reserved.

TiO 2 /SnO 2 composites prepared by mechanical mixing of TiO 2 and SnO 2 nanopowders over a full compositional range from 100 mol% TiO 2 to 100 mol% SnO 2 are characterized by BET adsorption, isotherms method, X-ray diffraction, Scanning Electron Microscopy, SEM, Transmission Electron Microscopy, TEM, spectrophotometry and impedance spectroscopy, IS. Gas sensors made of these nanopowders show high and reproducible responses in reaction with hydrogen at a relatively low temperature, not exceeding 400 °C. Remarkable increase in the sensor sensitivity accompanies mixing of SnO 2 nanopowder with a small amount (2 mol%) of TiO 2 . This effect can be accounted for by an enhanced oxygen preadsorption on SnO 2 grains due to the electron transfer from TiO 2 to SnO 2 .

The Polish Grid Initiative commenced in 2009 as a part of the PL-Grid project funded under the framework of the Innovative Economy Operational Programme. The main purpose of this Project was to provide the Polish scientific community with an IT basic platform making use of Grid computer clusters, enabling e-science research in various fields. The Project established a country-wide computing infrastructure, which supports scientific research through integration of experimental data and results of advanced computer simulations carried out by geographically-dispersed teams. The solutions applied in setting up this e-infrastructure ensured integration with other similar platforms around the world. The Polish Grid Infrastructure created within the PL-Grid project will be continuously maintained and extended as a new, 3-year project (2012-2014) that has started recently: "PLGrid PLUS: Polish Roadmap toward Domain-Specific Infrastructure for Supporting Computational Science in European Research Area". Its most important task is preparation of specific computing environments – so called domain grids – I.e., solutions, services and extended infrastructure (including software), tailored to the needs of different groups of scientists. The paper will outline the current status of the basic IT infrastructure in Poland and plans for the future – federated, domain-specific solutions of the extended PL-Grid platform. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

This paper describes the security framework used by the GridSpace2 platform. The framework needs to restrict access to the Experiment Workbench to authorized users only as well as enable scientists to use multiple resources - computers (such as clusters, grids and clouds) and data, like e.g. relational database management systems (RDBMSes). The paper analyzes the appropriate technologies, details the proposed solution and summarizes the results of our research and development of flexible and extensible security solutions for scientists who need transparent access to heterogeneous compute and data resources. Additionally, as part of this paper, a wallet mechanism is described which enables secure storage of arbitrary confidential data such as credentials for external services. © 2012 Springer-Verlag Berlin Heidelberg.
