CURRENT STATE OF THE SMALL RPAS MAINTENAN CE IN THE CZECH REPUBLIC
No full textThis paper summarize a current state of a small unmanned aerial vehicles maintenance at the territory of the Czech Republic. The word “small” means unmanned vehicles with the maximum take-off mass not exceeding 20 kg. A reader becomes familiar with a RPAS (Remotely Piloted Aerial Systems) maintenance issues an also with a legislation in the first part of the paper. The legislation determines requirements for their maintenance. The next part describes the current state of this type of the maintenance. The last part of the paper deals with the future of the small RPAS maintenance. There is a rough estimate of a future maintenance development in this part of the paper. There also are a possible solutions of these issues in this part. These things are there because the authors think that there is a space for a RPAS maintenance improving
INTERSECTION NODE OF PREFERRED TRANSPORT MODES AND ITS MODEL CROSSING FOR CYCLISTS PARDUBICE PALACKÉHO
No full textČlánek je zaměřen na specifický kolizní bod dvou obecně preferovaných druhů dopravy – veřejné hromadné osobní dopravy a cyklistické dopravy. Řešen je světelně řízený přejezd pro cyklisty na Palackého třídě v Pardubicích, kde tím dochází ke zpomalování a zastavování části vozidel MHD a veřejné linkové dopravy. Provozní situace je vyhodnocena na základě realizovaných dopravních průzkumů. Dále je proveden výpočet propustnosti kolizního bodu. S cílem zlepšení kvality provozu je navrženo zřízení preference veřejné hromadné dopravy při činnosti světelného signalizačního zařízení. Tento návrh je vyhodnocen za tímto účelem vytvořeným simulačním modelem. V článku jsou uvedeny jak aspekty realizace preference v tomto praktickém případě, tak teoretické aspekty metod využitých při jejím posuzování.The paper is focused on specific intersection node of two types of transport – public mass passenger transport and cyclist transport. Both of these transport kinds are preferred in general way. Crossing for cyclists equipped with traffic lights located on Palackého Street in Pardubice is solved. Decelerations and stopping of a part of (urban, suburban as well as long-distance) public transport vehicles (connections) are occurred there. Operational situation is evaluated on the base of realized transport surveys. Capacity calculation of this intersection node is done next to it. Application of preference for public passenger transport in operation of traffic lights is proposed with an aim to improve the quality of operation. This proposal is evaluated by utilizing of simulation model, designed for this purpose. There are mentioned aspects for practical realisation of preference at this place as well as theoretical aspects for methods utilized for this evaluation
SATELLITE NAVIGATION AND ITS IMPORTANCE IN TRANSPORTATION
No full textSatellite navigation systems have become nowadays very common and people can see them everywhere. Their use in transport is currently indispensable. Just the fact that navigation systems are very useful and necessary leads to the expansion of available systems.

The Living Presence of Invisible Agencies and Unseen Powers – The Dramatised and Reinvented History of Peter Ackroyd’s Novels
No full textThe voluminous body of work of Peter Ackroyd, one of the most versatile contemporary British writers, comprises chiefly of non-fiction and fiction. The first is dominated by his books on English history, English literature, the history and development of London, and a series of biographies of outstanding personalities he labels “Cockney Visionaries”, the latter by his novels. Taking some of the recent tendencies in historical fiction as a frame of reference and focusing on Ackroyd’s novels set solely in the past and both in the past and the present, this article examines how the various sides of his professional self – an historian, literary historian, biographer and writer – combine and intersect in his rendering and re-enacting history as a lively material and inheritance that can still be palpable in and illuminating for our present experience
The Grotesque Body and Ageing in A.S.Byatt’s Short Fiction
No full textThe paper deals with the work of the novelist Antonia Susan Byatt who became attracted to the short story genre which she often uses to express her fantastic ideas concerning the human body and its transformations, including ageing and death. Byatt often presents the human body as grotesque – it is deformed, hybrid, and/or monstrous. In her stories, the human bodies changed by circumstances or other factors usually signify the characters’ crisis in which they create new autonomies, new forms of existence. The paper discusses Byatt’s way of using the grotesque in depicting ageing and illness of her protagonists. The analysis is focused on two short stories from Little Black Book of Stories (2003) and explores the protagonists’ identity disintegration and body transformation as a result of inevitable life processes and the perception of human life as fragile and unstable
