Training and periodization for snowboard cross, parallel slalom and parallel giant slalom
2012
Snowboarding is a popular recreational sport, but it is also an elite sport. Snowboarding has been an Olympic sport since 1998. There will be five different snowboarding disciplines competed in Winter Olympics in Sochi 2014 (half-pipe, parallel giant slalom, parallel slalom, snowboard cross and slopestyle). Most of the snowboard cross and parallel event competitions are organized by International Ski Federation (FIS). FIS also organizes the World Cup and every second year Snowboard World Championships. Snowboarding environment is challenging. Riders are frequently exposed to training in cold environments and at high altitudes. Because snowboarding is a technical sport snowboarders spend ext…
Improvements and applications of the elements of prototype-based clustering
2018
Clustering or cluster analysis is an essential part of data mining, machine learning, and pattern recognition. The most popularly applied clustering methods are partitioning-based or prototype-based methods. Prototype-based clustering methods usually have easy implementability and good scalability. These methods, such as K-means clustering, have been used for different applications in various fields. On the other hand, prototype-based clustering methods are typically sensitive to initialization, and the selection of the number of clusters for knowledge discovery purposes is not straightforward. In the era of big data, in high-velocity, ever-growing datasets, which can also be erroneous, outl…

Methyl 3',4',5'-trimethoxybiphenyl-4-carboxylate
2013
In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the molecules are packed in an antiparallel fashion in layers along the a axis. In each layer, very weak C-H...O hydrogen bonds occur between the methoxy and methyl ester groups. Weak C-H...[pi] interactions between the 4'- and 5'-methoxy groups and neighbouring benzene rings [methoxy-C-ring centroid distances = 4.075 and 3.486 Å, respectively] connect the layers.
Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite systems
2020
Over the last few years, extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high degree of precision. An appealing and challenging route toward engineering materials with tailored properties is to find ways to design or selectively manipulate materials, especially at the quantum level. To this end, having a state-of-the-art ab initio computer simulation tool that enables a reliable and accurate simulation of light-induced changes in the physical and chemical properties of complex systems is of utmost importance. The first principles real-space-based Octopus project was born with that idea in mind,…
Kinematic and Elastostatic Design Optimisation of the 3-DOF Gantry-Tau Parallel Kinematic Manipulator
2009
Published version of an article in the journal: Modeling Identification and Control. Also available from the publisher:http://dx.doi.org/10.4173/mic.2009.2.1 One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The Gantry-Tau improves this ration further by allowing a change of assembly mode without internal link collisions or collisions between the links and end-effector. The reconfigurable Gantry-Tau kinematic design obtained by multi-objective optimisation according to this paper gives the following features: 3-D workspace/footprint ration is more than 3.19, lowest Cartesian stiffness in the workspa…
Ekskurs VIII. Powołania Ezechiela na stróża Izraela Ez 3,16-21 oraz Ez 33,1-20 w świetle retoryki hebrajskiej
2020
Kontekstem badań była konstatacja, że wielu komentatorów różnie określa strukturę opisywanych fragmentów Księgi Ezechiela. Czytelnik może odnieść wrażenie, że jest to zrobione na wyczucie, a wyczucie nie jest metodą naukową. Dlatego celem przeprowadzonych badań było opracowanie struktury tekstu przy pomocy naukowych metod. Wykorzystano metodę retoryki hebrajskiej, którą opracował Roland Meynet. Uzyskano wyniki: Ez 3,16-21: A, A’, B, B’ lub A, B, A’, B’; Ez 33,1-20: A, B, B’, A’; Ez 33,2-6: A, B, C, D, E, F, G, H, I, H’, G’, F’, E’, D’, C’, B’, A’; Ez 33,7-20: A, B, C, D, E, F, E’, D’, C’, B’, A’. Żeby można było sformułować naukowe, ogólne konstatacje na temat Księgi Ezechiela potrzebny jes…

Trzy poziomy struktur i kompozycja w wyroczniach przeciw Egiptowi Księga Ezechiela rozdziały 29–32 w świetle retoryki hebrajskiej
2022
Kontekstem badań było to, że różni komentatorzy Księgi Ezechiela proponują różniące się między sobą struktury badanych tekstów. Większość z nich pracowała (nadal pracuje) metodami diachronicznymi. Zazwyczaj ci autorzy układają wersy w grupy i tym grupom nadają tytuły. Dlatego celem badań stało się odkrycie struktur opartych o wersy tekstu biblijnego. Można wtedy wskazać konkretne wersy (lub ich części, człony), których użył starożytny autor natchniony. Dlatego zastosowano metodę biblijnej retoryki hebrajskiej, która ma 3 etapy: analizę oddolną, analizę odgórną oraz interpretację teologiczną. W wyniku przeprowadzonych badań na pierwszych dwóch etapach odkryto, że teksty wyroczni przeciw Egip…
A Stochastic Algorithm Based on Fast Marching for Automatic Capacitance Extraction in Non-Manhattan Geometries
2014
WOS:000346854900026 (Nº de Acesso Web of Science) We present an algorithm for two- and three-dimensional capacitance analysis on multidielectric integrated circuits of arbitrary geometry. Our algorithm is stochastic in nature and as such fully parallelizable. It is intended to extract capacitance entries directly from a pixelized representation of the integrated circuit (IC), which can be produced from a scanning electron microscopy image. Preprocessing and monitoring of the capacitance calculation are kept to a minimum, thanks to the use of distance maps automatically generated with a fast marching technique. Numerical validation of the algorithm shows that the systematic error of the algo…
