Design and analysis of racing pneumobile frame

Tato bakalářská práce reaguje na změny v pravidlech pro nový ročník soutěže Aventics Pneumobil a současně navrhuje řešení problémů ovlivňujících jízdní vlastnosti, které byly zjištěny během předchozích ročníků. Částí práce je analyzovat potíže stávajících rámů pneumobilů Ústavu Konstruování na VUT v Brně a navrhnout nový koncept rámu eliminující předchozí potíže. Obsahuje základní informace o soutěži Aventics Pneumobil a její pravidla, která se týkají této práce. Pro návrh rámu je potřeba znát vstupní parametry vozidla. Práce se také zaměřuje na výběr prvků pohonné soustavy, návrh několika koncepčních řešení, jejich porovnání s ohledem na požadované vlastnosti vozidla. Těžištěm práce je konstrukční řešení. Na základě vybraného konceptu je vytvořený podrobný CAD model vozidla. Jsou definovány limitní stavy zatížení v provozu a model je dále přenesen do softwaru pro řešení problému metodou konečných prvků, kde je zatěžován. Závěrem jsou shrnuty výsledky práce a doporučen další postup.This bachelor thesis reacts to the changes in the Aventics Pneumobil competition in the new season and proposes a solution to eliminate problems affecting drivability of the vehicle which were identified previously. Part of this thesis aims to analyze recent Institute of machine and industrial design at Brno University of Technology’s pneumobile vehicles frames and their problems. It also contains a whole new frame designing process. There are basic informations about the Aventics Pneumobil competition and its rules connected to this thesis. The process of designing a new frame requests a lot of input quantities of the vehicle. A lot of them were unknown and had to be set in order to gain the desired vehicle properties. The main part of the thesis is the construction part. A detailed CAD model is designed on the basis of chosen vehicle concept. It is then exported into a Finite element software for a strength analysis. All results are summarized in the conclusion and the next procedure is recommended

Prostorové modelování báze dubňanské sloje v moravské ústřední prohlubni (česká část Vídeňské pánve)

This paper deals with the methodology of modelling the Dubňany lignite seam base and its tectonic failure. Tectonic pattern of the Vienna Basin has been subject of many studies. Opinions on its origin have been developing. Coal seams in the South Moravian Lignite Coalfield were modelled under the project of the example modern evaluation of the coal deposit. Designed software with application of modern mathematical, statistical and geostatistical methods and SURFER program were used for coal seam modelling. Input data were taken from detailed mining, deposit and well exploration carried out for more than 50 years.Příspěvek je věnován metodice digitálního modelování báze dubňanské lignitové sloje a jejího tektonického porušení. Tektonická stavba vídeňské pánve je předmětem mnoha studií a názory na její genezi se stále vyvíjejí. Podrobné modelování slojí jihomoravského lignitového revíru bylo provedeno v rámci vzorového komplexního hodnocení uhelného ložiska v prostředí programu SURFER a pomocí účelově sestaveného programového systému s využitím moderních matematických, statistických a geostatistických metod. Vstupní data tvořily údaje o sloji a jejím okolí získané v minulosti během více než padesátiletého podrobného důlního, ložiskového a vrtného průzkumu

Relationship between the armed arm’s motor response and muscle activation time during the lunge in fencers of varied ability

The present work studied potential differences in activation times of selected muscles associated with the motor responses of the armed arm and differences in selected muscle pairs activation during the fencing lunge. Twenty-eight fencers (epée fencers, aged 23.1 ± 5.4 years) grouped into elite and beginning skill levels, participated in this study. Surface electromyography was used to determine muscle activation time (time period measured from visual stimulus occurrence to the moment of muscle activation threshold detection). For motor response, we measured the time between visual stimulus occurrence and armed arm movement. A significant difference was found between elite and beginning fencers in the motor response of the armed arm. Detection of armed arm’s motor response was significantly later in beginners. Greater time disparities between arm’s motor response and muscle activation time of the m. rectus femoris on the front/lunge side was also found in beginners. Lastly, difference was detected between elite and beginning fencers regarding the muscle activation time of selected muscle pairs. Future studies and trainers can use these results to further explore key areas of motor control and biomechanics for improving of fencing performance

Forest leaf litter beetles of Taiwan: first DNA barcodes and first insight into the fauna

We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive

A computational analysis of the apparent nido vs. hypho conflict : are we dealing with six- or eight-vertex open-face diheteroboranes?

A series of computational studies have been undertaken to investigate the electronic structures and bonding schemes for six hetero-substituted borane cages, all of which have been presented in the literature as potential hypho structures. The six species are hypho-7,8-[C2B6H13]- ( 1a ), hypho-7,8-[CSB6H11]- ( 1b ), hypho-7,8-[S2B6H9]- ( 1c ), hypho-7,8-[NSB6H11] ( 1d ), exo-7-Me-hypho-7,8-[NCB6H12] ( 1e ), and endo-7-Me-hypho-7,8-[NCB6H12] ( 1f ) and the so-called mno rule has been applied to each of them. As no structural data are known for the carbathia-, azathia-, and dithiahexaboranes, we have also applied the ab initio/GIAO/NMR structural tool for 1b-1d , with 1c having been prepared for this purpose. We conclude that an mno count of 10 means that 1a , 1b , 1d , 1e , and 1f should be termed pseudo-nido or pseudo-hypho. Only can be considered to be correctly termed hypho-7,8-[S2B6H9]-
