Jan Kapr's contribution to contemporary music : an essay about a composer and teacher
No full textThis creative project is a treatise on a leading personality of Czechoslovakian musical life, the composer, Jan Kapr. The author discusses the following:1. The complicated development of Kapr's career and work, 2. Kapr's method of organization of musical material in a composition, as described in his book Constants,3. His former and current style which is demonstrated in two of his compositions, Concert Variations, for flute and string orchestra and Testimonies for four solo instruments,4. Two of his recent works, Exercises for Gydli and the Symphony No. 7, Country of Childhood.Thesis (M.A.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ELEVEN FACES OF JAN GOGOL, JR.
No full textAuthor Jan Rendl in his thesis attempts to look at the world of ideas and educator Jan
Gogola ml. through the eleven chapters in which each chapter somehow characterizes itself by Jan Gogola ml. and each of them somehow determines its creative ideas of it through the metaphor of a football match when Jan Gogola, with its characters, movies himself a teammate, as well as defensively. It gives goals with their situations as well as occasionally digging his opponents ankles.
Jan Gogola ml. thus embodies one stage of the Department of Documentary Film at FAMU, which often stands at the intersection between teaching activities and Karel Vachek among students who applied by them during their seminars psychological methods that work must be peculiarly associated with the author of the film
Evaluating CSP as a programming model to build distributed systems
No full textIn this paper we investigate the use of the CSP programming model for implementing distributed systems in an educational setting. For a practical example we choose a well-studied classic distributed system: a distributed hash table. We describe our implementation and compare it to a number of existing open-source implementations. We discuss a number of parameters for the example implementation, such as amount of code, potential for errors, and similar parameters.</p

MUMMERING Platform Idea's & ubiquitous data analysis
No full textThe growth from terabytes of 3D imaging data and soon approaching petabytes from material analysis has left the scientists involved with a set of challenges. In particular, the ability to efficiently analyze an ever growing collection of material tomography scans. The MUMMERING research project aims to solve this by providing ability to submit workflows to automate the process of analyzing the collected data. We explore and present our initial design thoughts in this endeavor. This includes a proposal to utilize the IDMC system developed at UCPH to provide an efficient method in terms of scheduling and execution of workflows. Beyond this mere exploration of thoughts about a potential solution for the MUMMERING project, this paper will also we introduce our initial work in providing ubiquitous access to the produced datasets. The aim here is to provide a simple API for loading/storing datasets during an image analysis, by providing this universal data access library (i,e. mig utils). With this we hope to help the non computer scientists involved in defining imaging analysis programs that easily either can executed locally during the experimentation phase or subsequently scheduled by a workflow scheduler.</p
Big data analysis with skeletons on SOFA
No full textThis paper explores how a skeleton based approach can be used to perform big data analysis. We introduce a restricted storage system based on blocks with a fixed maximum size. The storage design removes the residual data problem commonly found in storage systems, and enables processing on individual blocks. We then introduce a stream-oriented query system that can be used on top of the distributed storage system. The query system is built on a limited number of core operations. Each of the perform a specified function, such as filtering elements, but are skeleton operations where the programmer needs to fill in how to perform the operation. The operations are designed to allow splitting across the blocks in the storage system, giving concurrent execution while maintaining a completely sequential program description. To assist in understanding the data flow, we also introduce a graphical representation for each of the methods, enabling a visual expression of an algorithm. To evaluate the query system we implement a number of classic Big-Data queries and show how to implement them with code, and how the queries can be visualized with the graphical representation.</p
Concurrent composition of I/O redundancy behaviors in Go
No full textThe Go programming language defines simple I/O interfaces that any data type may implement. In this paper we introduce a Go package that allows arbitrary implementations of these interfaces to be composed into RAID-like redundant (and/or) high-performance striped arrays. The package also allows spares to be added for fail-over functionality. The package is focused on providing a highly available write setting that tolerates multiple failures but can always receive data as long as a single redundant path exists. This is achieved by allowing reads to become unavailable in the presence of failures that cannot be solved while the array is operating. The package is highly concurrent and parallelized and exploits the Go programming language's built-in light-weight concurrency features.</p
Bohrium.rb - The Ruby front end
No full textThe acceptance of Ruby in the scientific community lags a bit behind, partly because it is missing a good library for linear algebra and vector programming. It has a matrix class in its standard library, but its execution tends to be rather slow. Only a couple of actual scientific computing libraries like NumPy for Python exist for Ruby. In this paper we introduce a new library called Bohrium.rb. Bohrium.rb acts as a front end for the Bohrium framework, which generates and runs JIT-compiled OpenMP/OpenCL kernels. It currently supports Python/NumPy and C++, however as it is built of processes communicating hierarchically to each other, we can replace the front ends with new ones. This new Ruby front end is described with examples and is then compared to the standard library and an already established Ruby library Numo/Narray, where Bohrium.rb seems to be faster for still larger matrix calculations. This is also the trend we have seen in similar areas with Bohrium, being faster once its overhead has been amortized.</p
