University Institutional Repository and its Place in the University Information Infrastructure
Pilecká, Věra; Kováříková, Helena; Němečková, Lenka; Machytková, Marta; Prajer, Ivo; Karel, Petr
2014 - English
University repositories are no isolated archives. They provide significant added value to the existing university information infrastructure, and its integration within the university information system is essential. The Czech Technical University in Prague (CTU) systematically builds its repository and integrates it within various subsystems of the university information system. It provides mutual advantage. The repository uses existing data and in return it enriches the information infrastructure of the university with the archiving tool and its content. This paper discusses technical and process solution to the interconnection of university repository (DSpace platform) with individual subsystems of the university information system, and the design of the optimized data flow and data management between the entities/components involved. The intention is to optimize the university data workflow – multiple uses of data (which have once been entered by various subsystems of the information system) to automatically manage repository structure and create its content without the need of frequent manual intervention. The article introduces the interconnection of individual components, subsystems and processes related to the university institutional repository, and describes the role of individual item and data flow in the process. Keywords: University repository infrastructure; University information system; University repository integration; University data workflow Available in digital repository of ČVUT.

Context Sensitive Navigation in Hospitals
Balata, Jan; Macík, Miroslav; Míkovec, Zdeněk
2013 - English
In this paper we introduce an in-hospital navigation system suitable for motor impaired, visually impaired and elderly people. GPS localisation and WiFi triangulation are often not suitable in indoor environments due to poor signal or complicated calibration. We present a navigation system that does not depend on precise electronic localisation aids. User interfaces used are automatically accustomed to target user's abilities and preferences. Four di erent terminal types are used for the navigation system prototype. Keywords: navigation; UI generation; context modelling; accessibility Available in digital repository of ČVUT.

Synchronous Phasors Monitoring System Application Possibilities
Kasembe, Andrew G.; Müller, Zdeněk; Švec, Jan; Tlustý, Josef; Valouch, Viktor
2012 - English
The paper deals with some tasks of advanced methods to achieve security and reliability of transmission power systems. There are discussed advanced principles and techniques in monitoring systems. The paper main part is devoted to possible applications of PMUs (Phasor Measurement Unit) and their integration into WAMPaC systems (Wide Area Monitoring, Protection and Control). Significant transmission system states were analyzed in several case studies. PMUs utilization for voltage monitoring is demonstrated for three cases – standard system state, high-load state and islanding. Here the attention is paid to the possibilities of power system observability improvement using measuring chain error elimination. Other possible applications in transmission systems include ampacity determination of transmission corridors, the calculation of line electrical parameters using synchrophasor measurement, state estimation issues and power system stability. The power system model was established for methods and algorithms verification purposes. The appropriate algorithms and their parameters were found using simulation outputs to create the local automatics, e.g. Automatic Power System Stabilizer (PSS). Keywords: Phasor Measurement Unit; Wide Area Monitoring System; Transmission System; Power System Stability; Extraordinary States; Black-out; Loop Flows Available in digital repository of ČVUT.

Gaussian Logic for Predictive Classification
Kuželka, Ondřej; Szabóová, Andrea; Holec, Matěj; Železný, Filip
2011 - English
We describe a statistical relational learning framework called Gaussian Logic capable to work efficiently with combinations of relational and numerical data. The framework assumes that, for a fixed relational structure, the numerical data can be modelled by a multivariate normal distribution. We demonstrate how the Gaussian Logic framework can be applied to predictive classification problems. In experiments, we first show an application of the framework for the prediction of DNAbinding propensity of proteins. Next, we show how the Gaussian Logic framework can be used to find motifs describing highly correlated gene groups in gene-expression data which are then used in a set-level-based classification method. Keywords: Statistical Relational Learning; Proteomics; Gene Expression Available in digital repository of ČVUT.

3D Ultrasound real-time monitoring of surgical tools
Gaufillet, Fabian; Liebgott, Hervé; Uherčík, Marián; Cervenansky, Fréderic; Kybic, Jan; Cachard, Christian
2010 -
To assist surgeons during their surgical operations, which involve a tool insertion, a real-time application which is able to localise the surgical tool during its movement is proposed. The position of the needle is estimated with a method based on model fitting using a Random Sample Consensus (RANSAC). Our proposed application has been implemented on the ULTRASONIX RP scanner and it permits 3D volumes acquisition, storage and the tool localization. The developed graphical user interface shows both the section plane containing the tool and the perpendicular plane to it in order to give a view of surrounding tissue. The performed experiments have shown that our application is able to display the correct frame that contains the needle and localize surgical tools in real time and with a good accuracy in water, polyvinyl alcohol cryogel phantom and liver tissue. Refresh rates of displaying the result is less than one second for volumes of size 67 × 128 × 224 voxels. The time required to acquire this volume is about one second with the 4DC7-3/40 3D probe. So our application works at real-time. Keywords: 3D Ultrasound; needle localization; RANSAC; real-time application Available in digital repository of ČVUT.

Thermomechanical Analysis of Electrically Conductive Adhesives
Mach, Pavel; Bušek, David; Polanský, Radek
2010 -
Mechanical properties of isotropic electrically conductive adhesives (ICAs) are mainly influenced by their formulation and thermal processing. Thermomechanical analysis of ICAs was used with the goal to find influence of addition of two types of nanoparticles, silver nanoballs and carbon nanotubes, and two types of curing processes, on air and in vacuum, on the glass transition temperature and storage modulus of bisphenol epoxy adhesives filled with silver flakes (70 to 80 % by weight). Specimens were formed as blocks. Three groups of specimens were fabricated: specimens of adhesives used as received and cured according to the recommendation of a supplier in air; specimens of adhesives used as received and cured according to the recommendation of a supplier in vacuum, specimens of the same adhesives added with low fraction (0,3 to 10 % by weight) of silver nanoballs, colloidal dispersion of silver, or carbon nanotubes. There were found differences in the glass transition temperatures and storage and loss moduli in dependence on the type of particles added into adhesive. It was also found that the adhesive cured in vacuum had lower thermal expansion coefficient and higher the storage and loss modulus in comparison with adhesive cured in air. Available in digital repository of ČVUT.
