The Study of the Production Process Selected Technologies
Rosecká, Eva ; Čech, Jan (referee) ; Jurová, Marie (advisor)
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.

Computer support for data distribution design - design laboratory
Benešová, Lucie ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
This thesis is concerned with data wiring infractructure. In the theoretical part the basic technology of the LAN networks is described as well as its parts, such as HUB and switch. Various types of transfer paths used in data wiring are briefly mentioned. They included coaxial cable, which were then replaced by shielded twisted pair and in future the fibre optics cables will be used instead. The shielded twisted pair operates on structured cabelling, which is guided by central principles in designing, which then can guarantee 15 years of good service. The most used cables 5e and 6 are described. The next chapter describes the endings of cables and connectors as well as the principles of patch pannels and patch cables. The following parts focus on the fibre optics networks, because they are the networks of the future. The types of fibre optics cables are described together with networks standards, the minimal fibre radius and innovations such as WDM or micropipes. There is also a resume of the ČSN norms, which are important for this thesis, concerning issues of the ways how to lay cables, placing of the communications etc. In the practical part, the various softwares for designing data wiring infractructure are studied and compared. As the most convinient for student proposals the AutoCAD Electrical 2011 has been chosen. This design software is studied from the point of view of its user interface and basic rules of behaviour. The functions of the menus and pripary settings are described. In the last part of the thesis the lesson is provided. The lesson should give students basic information and opportunity to design a basic data wiring infrastructure for a building.

Evacuation of a Large Hospital
ŽÁČEK, Radovan
Act no. 328/2001 of the Collection of Laws defines that, apart from others, evacuation must be planned for handling emergency situations that require an alarm of the third or spe-cial degree to be raised. Successful evacuation requires an evacuation plan be made as part of crisis preparedness plans and this project could become a template for preparing evacuation plans for emergency situations at Fakultní nemocnice (a teaching hospital) in Motol, Prague. The teaching hospital in Motol is one of the largest hospitals in central Europe. It has 2,500 beds at its disposal, 350 of which are with intensive care. The hospital has large prem-ises the heart of which consists of two monoblocks, one for children patients and the other for adult ones. The other buildings in the hospital house its technical and administrative facilities or some special departments. The set of persons in question includes all the people in danger on the premises at the time of raised evacuation. It means hospitalized patients, outpatient ones, employees, students and teachers of the 2. Lékařská fakulta UK (the Medical Faculty of Charles University) and visitors. The objective of this work is to create model templates for evacuation plans for se-lected wards as well as larger departments, including the entire hospital complex. The other objective is to verify, or refute, the hypothesis that evacuation, partial or complete, of a large hospital can be finished within 12 hours. The methodology was based on detailed data collection about each ward and bed de-partments (location, number of beds, number of staff at various time of the day etc). Another source of information was a detailed survey of the entire premises focused at finding potential evacuation routes inside as well as outside the buildings, capacity of corridors, stairways, lifts, and other important information related to evacuation. The results of the project are presented in the form of ten model evacuation plans for various individual parts as well as whole units of the hospital: 1. Evacuation of one ward of the children{\crq}s monoblock, 2. Evacuation of one wing of the children{\crq}s monoblock, 3. Entire evacuation of the children{\crq}s monoblock, 4. Evacuation of one ward of the adult{\crq}s monoblock, 5. Evacuation of one floor in one communication node of the adult{\crq}s monoblock, 6. Evacua-tion of one entire communication node of the adult{\crq}s monoblock, 7. Entire evacuation of the adult{\crq}s monoblock, 8. Evacuation of the other hospital facilities, 9. Evacuation of another pa-vilion, 10. Entire evacuation of the whole hospital. The final results show that it is not possible to have one universal evacuation plan that would include all potential situations but several plans for particular kinds of exposure and sizes of departments in danger. The hypothesis was verified for variants 1., 2., 3., 4., 5., 6., 8. and 9. but it was not verified for variants 7. and 10. Evacuation of the entire adult{\crq}s mon-oblock and evacuation of the whole hospital cannot be finished within 12 hours after alert.
