Diploma thesis "Launch of the public-service culture channel: Broadcast analysis of ČT art until the year 2014" describes the origin and development of the channel ČT art, including an analysis of how it influenced the transformation of ČT2. This thesis, therefore, includes the programme composition of both channels monitoring the period from autumn 2013 to autumn 2014, as well as the programme composition of ČT2 from autumn 2012. This allows us to evaluate how ČT2 attended to cultural broadcasting before the launch of the new and thematically specialized channel ČT art. Moreover, the thesis tries to point out the trends taking place in television broadcasting such as digitalization, fragmentation of TV audiences and media convergence. These trends are illustrated by using specific examples from the Czech Television, as well as the theoretical foundation. The theoretical part of the thesis focuses on describing public-service media, services they provide and their roles in fulfilling the cultural needs of society. In addition, it also draws attention to examples of culturally oriented channels within Europe. The results of the analysis of programme schemes of both channels are complemented by findings from interviews with the leading employees of the Czech Television, which were not aimed to focus...

Parallel programming is becoming mainstream due to the increased availability
of multiprocessor and multicore architectures and the need to solve larger and
more complex problems. Languages and tools available for the development of
parallel applications are often difficult to learn and use. The Standard Template
Adaptive Parallel Library (STAPL) is being developed to help programmers
address these difficulties.
STAPL is a parallel C++ library with functionality similar to STL, the ISO
adopted C++ Standard Template Library. STAPL provides
a collection of parallel pContainers for data storage and pViews that
provide uniform data access operations by abstracting away the details of
the pContainer data distribution. Generic pAlgorithms are written in terms of PARAGRAPHs,
high level task graphs expressed as a composition of common parallel patterns.
These task graphs define a set of operations on pViews as well as any
ordering (i.e., dependences) on these operations that must be enforced by
STAPL for a valid execution. The subject of this dissertation is the PARAGRAPH Executor,
a framework that manages the runtime instantiation and execution of STAPL
PARAGRAPHS.
We address several challenges present when using a task graph program representation
and discuss a novel approach to dependence specification which allows task graph creation
and execution to proceed concurrently. This overlapping increases scalability and
reduces the resources required by the PARAGRAPH Executor. We also describe the interface for task
specification as well as optimizations that address issues such as data locality.
We evaluate the performance of the PARAGRAPH Executor on several parallel machines including
massively parallel Cray XT4 and Cray XE6 systems and an IBM Power5 cluster.
Using tests including generic parallel algorithms, kernels from the NAS NPB suite,
and a nuclear particle transport application written in STAPL, we demonstrate that the
PARAGRAPH Executor enables STAPL to ex
We analyze rnetasystem transitions which may be observed, or are intentionally used, in computer science and mathematics. Various metasystem structures are present in their activities of executing, creating and manipu...
