BEHAVIORAL ECONOMICS AND CYBER CRIME

This article deals with the problem of cybercrime. The main objective of this piece is to present a proposal of possible solutions to software piracy. To solve the problem, knowledge from the field of behavioral economics will be used, which will be presented in the second chapter of the article. The authors identify the causes of computer piracy and have subsequently concluded that in order to curb piracy, it is key that producers respect the social contract between them and the customers and that they act upon customer´s moral consciousness, instead of threatening punishment

Use of CSS libraries within the React framework

This bachelor thesis shows the possibilities of developing websites or applications using the React framework. Furthermore, three CSS libraries - Tailwind CSS, Bootstrap and Material UI are selected, at the same time useful tools are mentioned in the course that make working with both React and CSS libraries easier. These tools and libraries are then applied in practice on a model application, which is available in three versions of the mentioned CSS libraries. The result of the work is a comparison and evaluation of the experience with these libraries using the React framework.Tato bakalářská práce má za cíl ukázat možnosti vývoje webových stránek či aplikací za použití aplikačního rámce React. Za tímto účelem jsou vybrány tři CSS knihovny - Tailwind CSS, Bootstrap a Material UI. Dále jsou v průběhu zmiňované užitečné nástroje, které ulehčují práci jak s aplikačním rámcem React tak s CSS knihovnami. Tyto nástroje a knihovny jsou následně využity v praxi na modelové aplikaci, která je dostupná ve třech verzích zmíněných CSS knihoven. Výsledkem práce je porovnaní a zhodnocení zkušeností s těmito knihovnami za použití aplikačního rámce React.Katedra informačních technologií a technické výchovyFaculty of EducationPedagogická fakult

On the 3D distribution and size fractionation of microparticles in a serpentine microchannel

Suitable methods to realize a multi-dimensional fractionation of microparticles smaller than 10 μm diameter are still rare. In the present study, size and density fractionation is investigated for 3.55 μm and 9.87 μm particles in a sharp-corner serpentine microchannel of cross-sectional aspect ratio h∕w = 0.25 . Experimental results are obtained through Astigmatism Particle Tracking Velocimetry (APTV) measurements, from which three-dimensional particle distributions are reconstructed for Reynolds numbers between 100 and 150. The 3D reconstruction shows for the first time that equilibrium trajectories do not only develop over the channel width, i.e. in-plane equilibrium positions but also over the channel height at different out-of-plane positions. With increasing Reynolds number, 9.87 μm polystyrene (PS = 1.05 g cm−3) and melamine (MF = 1.51 g cm−3) particles focus on two trajectories near the channel bisector. In contrast to this, it is shown that 3.55 μm polystyrene particles develop four equilibrium trajectories at different in-plane and out-of-plane positions up to a critical Reynolds number. Beyond this critical Reynolds number, also these particles merge to two trajectories at different channel heights. While the rearrangement of 3.55 μm polystyrene particles just starts beyond Re > 140 , 9.87 μm polystyrene particles undergo this rearrangement already at Re = 100 . As the equilibrium trajectories of these two particle groups are located at similar out-of-plane positions, outlet geometries that aim to separate particles along the channel width turn out to be a good choice for size fractionation. Indeed, polystyrene particles of different size assume laterally well-separated equilibrium trajectories such that a size fractionation of nearly 100% at Re = 110 can be achieved

Accelerated Particle Separation in a DLD Device at Re > 1 Investigated by Means of µPIV.

A pressure resistant and optically accessible deterministic lateral displacement (DLD) device was designed and microfabricated from silicon and glass for high-throughput fractionation of particles between 3.0 and 7.0 µm comprising array segments of varying tilt angles with a post size of 5 µm. The design was supported by computational fluid dynamic (CFD) simulations using OpenFOAM software. Simulations indicated a change in the critical particle diameter for fractionation at higher Reynolds numbers. This was experimentally confirmed by microparticle image velocimetry (µPIV) in the DLD device with tracer particles of 0.86 µm. At Reynolds numbers above 8 an asymmetric flow field pattern between posts could be observed. Furthermore, the new DLD device allowed successful fractionation of 2 µm and 5 µm fluorescent polystyrene particles at Re = 0.5-25

Using Social Networking in Education

The subject of diploma thesis are online social networks and how they can be used in education. The first part deals how social networks can help in education, it analyses communi-cation as crucial aspect educational process. Theoretical part is also trying to define online social network with the aim on education, few of social networks are presented with exam-ples how can they be used in practise. The practical part consists in the implementation of a chosen social network (proba-bly Yammer) into the real teaching courses of the Department of system analysis - intro-ductory on subjects 4SA615 - Information Management and 4SA526 - New media and social networks. Questionnaire is used to evaluate the results and to get feedback from the student on the implemented project (social network). Recommendations are proposed based on the feedback, which could be applied to improve the courses in upcoming semes-ters. In the best-case scenario, the conclusion of this diploma thesis could lead to imple-menting the social network for whole department, or even university

Comparison of non-contact temperature measurement during maturation of compost measurement using surface and recessed sensors

The topic of the bachelor 's thesis is focuses on the comparison of the results obtained by contact measurement sensors and infrared (thermal imaging) camera. Their mutual comparison of the different stages of the composting process and determine the most appropriate method of obtaining information on the temperature of the fill. The information thus gathered should help to streamline their own process of composting. The object of this work isn 't the evaluation or monitoring of composting process

Vliv jednotlivých komponent směsných krmných dávek u krmných míchacích vozů (bez vybírací frézy) na přesnost nakládek

Topics thesis focuses on the feed mixing wagons, specifically on the impact of individual components of mixed feed rations with feed mixer wagons without pickup cutters accuracy loads. The result of this work is your own assessment of the qualitative characteristics of individual components of mixed feed rations, but their influence on the possible inaccuracy of the weighing equipment of these vehicles and thus on the actual composition of the diet and the resulting measures to prevent the occurrence of these inaccuracies when preparing feed
