Vsetin - Velke Karlovice Railway Track Refurbishment (section between km 17,000 - 19,950 km) Including Track Laying Technology

Bakalářská práce se zabývá rekonstrukcí železničního svršku a úpravou geometrických parametrů koleje na vybraném úseku železniční tratě Vsetín – Velké Karlovice. Při návrhu je brán zřetel především na stávající objekty tratě, a to přejezdy, propustky, zastávky, mostní objekty apod. Součástí práce je také návrh obnovy odvodnění tratě a technologie prací. Veškeré úpravy jsou v souladu s platnými právními předpisy.Bachelor´s thesis deals with design of permanent way and track geometry parameters of the selected section of Vsetín – Velké Karlovice railway track. The design should be considered primarily on existing objects such as railway crossings, culverts, railway stops, bridges , etc. Thesis includes restoration of drainage and track laying technology. It should be noted, that all proposed adjustments are designed according to current regulations and legislation.

Dynamic Template Adjustment in Continuous Keystroke Dynamics

Dynamika úhozů kláves je jednou z behaviorálních biometrických charakteristik, kterou je možné použít pro průběžnou autentizaci uživatelů. Vzhledem k tomu, že styl psaní na klávesnici se v čase mění, je potřeba rovněž upravovat biometrickou šablonu. Tímto problémem se dosud, alespoň pokud je autorovi známo, žádná studie nezabývala. Tato diplomová práce se pokouší tuto mezeru zaplnit. S pomocí dat o časování úhozů od 22 dobrovolníků bylo otestováno několik technik klasifikace, zda je možné je upravit na online klasifikátory, zdokonalující se bez učitele. Výrazné zlepšení v rozpoznání útočníka bylo zaznamenáno u jednotřídového statistického klasifikátoru založeného na normované Euklidovské vzdálenosti, v průměru o 23,7 % proti původní verzi bez adaptace, zlepšení však bylo pozorováno u všech testovacích sad. Změna míry rozpoznání správného uživatele se oproti tomu různila, avšak stále zůstávala na přijatelných hodnotách.Keystroke dynamics is one of behavioural biometric characteristics which can be employed for continuous user authentication. As typing style on a keyboard changes in time, the template adapting is necessary. No study covered this topic yet, as far as the author knows. This master thesis tries to fill this gap. Several classification techniques were exercised with help of keystroke data from 22 volunteers in order to test if they can be improved to unsupervised online classifiers. A significant improvement in impostor recognition was noted at one-class statistical classifier based on normed Euclidean distance. The impostor could make 23.7 % actions less than in offline version on average but the improvement was obseved with all test sets. In contrary, the genuine user recognition varied from user to user but it still kept at acceptable values.

Who gets the Carrot and Who gets the Stick? Evidence of Gender Disparities in Executive Remuneration

This paper offers a new explanation of the gender pay gap in leadership positions by examining the relationship between managerial bonuses and company performance. Drawing on findings of gender studies, agency theory, and the leadership literature, we argue that the gender pay gap is a context-specific phenomenon which results partly from the fact that company performance has a moderating impact on pay inequalities. Employing a matched sample of 192 female and male executive directors of UK listed firms we corroborate the existence of the gender pay disparities in corporate boardrooms. In line with our theoretical predictions, we find that bonuses awarded to men are not only larger than those allocated to women, but also that managerial compensation of male executive directors is much more performance-sensitive than that of female executives. The contribution of attributional and expectancy-related dynamics to these patterns is highlighted in line with previous work on gender stereotypes and implicit leadership theories such as the romance of leadership. Gender differences in risk-taking and confidence are also considered as potential explanations for the observed pay disparities. The implications of organizations’ indifference to women’s performance are examined in relation to issues surrounding the recognition and retention of female talent.executive compensation;gender pay gap;gender stereotypes;implicit leadership theories;corporate performance;romance of leadership

The glass cliff: Evidence that women and ethnic minorities contest “hopeless” seats

Are women and ethnic minorities set up to fail when they run in UK General Elections? Clara Kulich from the University of Geneva (Switzerland) presents findings from collaborative research with colleagues at the University of Exeter (UK) and the University of Queensland (Australia) which show that in past UK General Elections (2001 to 2010) women and ethnic minority candidates of the Conservative party were preferentially chosen to run for “hopeless seats” — that is, in constituencies where their party was likely to lose

The dependence of selected technical and combustion characteristics of fire on moisture levels in alternative fuels

The subject of this paper is to analyse the infl uence of moisture on selected technical and combustion characteristics of alternative fuels. The analyses are conducted on the basis of analyses of samples of alternative fuels simulating states of the fuel in expected operating conditions, focusing on the identifi cation of potential operational risks. The fi nal part consists of a set of recommended measures to ensure the operational safety of the practical use of alternative fuels based on the results of the analysis
