Studie výrobního procesu vybrané technologie / The Study of the Production Process Selected TechnologiesRosecká, Eva January 2015 (has links)
This work is focusing on the tracking of selected orders in a company which is mainly engaged in piece production of castings. The aim is, based on the tracking of the course of the pre-production and production phases, to analyse the production process bottlenecks. This is carried out by means of the information system used in the company and through daily tracking of the selected orders. The ascertained time data are divided into the time necessary for the production and the lost time. The scheduled and the actual production times, from order receipt up to the shipment of a finished casting, are entered in the Gantt diagram. In conclusion the work deals with the evaluation of the time lost in production and the proposals for making production more effective are offered.

Zrakové vnímání řidiče v dopravním provozu / Eye Perception of Drivers in TrafficVorálková, Kateřina January 2012 (has links)
The aim of thesis is a summary and assessment of perception of drivers in traffic from the view of psychology and its influence on various aspects and the resulting effects on driving. Furthermore, it is mainly a description of the visual system and the description of light as factor of visual perception. The thesis also presents two experiments refer to the reaction time and mental reactions of driver, depending on drank out alcohol. Results of the first test of reaction time starting at the traffic lights were just a confirmation of the mentioned values from different publications and the Internet. The results of the second test, which was focused on the emotional reaction depending on the amount of ingested alcohol would be surprising to many.

Analýza vlivu používání technických zařízení řidičem na reakční dobu / The impact analysis of the technical devices used by the driver on the reaction timeKubánek, Ondřej January 2016 (has links)
This master‘s thesis analyzes the impact of the use of technical equipment for the driver reaction time. There are described the legal requirements for the use of technical devices by the driver in the vehicle. There are analyzed the types of technical devices used by drivers and mainly discussed the issue of drivers' reaction times. They assessed factors affecting reaction time, ways of measuring the reaction time and the type of reaction times. They discussed earlier research from the beginning of the measurement of reaction times to the latest research, dealing with the measurement of reaction times when using a mobile phone. The practical part is devoted to perform road tests on a sample of drivers and evaluate their reaction times during normal driving and during a call. The measured and evaluated data are commented with respect to the benefits of expert activities in the field of transport.

Osídlení doby bronzové na lokalitě Vinoř-V Žabokřiku / Bronze Age Settlement in Vinoř-V ŽabokřikuKleinová, Kateřina January 2013 (has links)
This study describes results of analysis of findings obtained during the excavation of Knovíz settlement in Praha - Vinoř "V Žabokřiku". One whole above-ground structure was found and few more can be presumed besides the features. The residential area could be separated from the storege area. Great amount of pottery, loom weights, daub, stone industry and individual animal bones was found mostly in bigger features. This settlement represents Knovíz culture in Late Bronze Age (phases Br D - Ha A1) according to the pottery products' analysis. There is no evidence of other cultures. In the site there were breeded domestic animals, we can presume growing and proccessing corn, also textile production. There is no evidence of bronze itams pruduction. Keywords: Central Bohemia - Praha-Vinoř - Bronze Age - Knovíz culture - settlement - pottery

Studium lisovacího procesu a vlastností tablet z různých typů hydrogenfosforečnanu vápenatého. / A study of the compaction process and the properties of tablets from different types of calcium hydrogen phosphate.Koryťáková, Lenka January 2015 (has links)
The thesis evaluates anhydrous and dihydrate calcium hydrogen phosphate from the view point of the tensile strength, disintegration time of tablets depending on the compression force. Two firm products - Anhydrous Emcompress® and Di-Cafos® A 60 are used as anhydrate and Emcompress® is used as dihydrate. A compression force together with lubricants (magnesium stearate, sodium stearyl fumarate) and an addition of microcrystalline cellulose (Vivapur® 102) are the influential factors. In addition to the characteristics of tablets, the energy balance of compression is also evaluated. Used compression forces were 12, 16 and 20 kN. The compression force 12 kN was used for the mixtures containing Vivapur® 102. Total energy of compression, energy for friction and energy accumulated by tablet after compression increased with compression force. The highest values were at Anhydrous Emcompress® , an addition Vivapur® 102 increased these values. There weren't more significant differences among the values of decompression energy. Plasticity decreased with the growing compression force, the highest values were at Anhydrous Emcompress® , Vivapur® 102 increased that. Tensile strength increased with compression force, Emcompress® provided the strongest tablets, Di-Cafos® A 60 provided at least strong tablets. Vivapur...
