Vývoj globálního trhu s mikročipy / The Evolution of the Global Microchip Market

Srba, Lukáš Martin January 2015 (has links)
This thesis aims to explain the evolution and transformation of the microchip industry. It focuses on the changes and prediction of the future state including its causes and consequences. The analysis starts on the general description of the market and continues through its subjects ending on relationships between them. This serves as a source of information to the prediction in the final part of the thesis. In the beginning the products, which are taken into consideration in this work (namely CPUs, GPUs and APUs), are described. Following this, there is an analysis of the competition environment that defines a structure of the market upon which further work is based. (Three levels; the manufacturer of photolithographic machines, makers of the chips and their designers and OEM and aftermarket subjects.) The penultimate part defines the barriers to entry to this market and three categories are drawn up: economic, technical and geoeconomic, which are applied to every level of the market. Thus all prerequisites to a successful prediction are satisfied. In the last part of the thesis the prognosis is made and defined, along with its assumptions and limitations. In the concluding part of this work the consequences and results are summarized.

Návrh funkcionality ideálního chytrého domu / Proposal of ideal smart home functionality

Zumr, Jiří January 2012 (has links)
The house in which the family live, should be built for the specific lifestyle residents and respond intelligently to their current and changing needs. Nowadays there are some new buildings that have such requirements partially resolved. The proposed project is based on the situation of families living in older buildings that no longer complies with their needs. Therefore they are considering home reconstruction to transform house into so-called "smart" house or apartment. The project deals with the functioning of modern living that reflects the lifestyle and how to be a house or flat is used. It takes into account the location of individual system components (control and regulation elements, controls, cameras, sensors, audio-visual equipment, etc.), and their interconnection to the selected specific component types that are in keeping with the style and interior design. The work is based on the description of the ideal smart home functionality to create smart design solutions of selected house based on currently available technologies. Detailed design is developed using available technology to control home appliances.

Organické materiály pro molekulární elektroniku a fotoniku / Organic materials for molecular electronics and photonics

Vrchotová, Jana January 2019 (has links)
Organická elektronika je dynamické, rychle se rozvíjející odvětví. Studium nových materiálů pro organickou elektroniku je důležitým úkolem jak z hlediska výkonnosti budoucích zařízení a ekonomičnosti procesů, tak z hlediska vlivu jejich používání na životní prostředí. Deriváty diketopyrrolopyrrolu patří mezi zajímavé materiály, které jsou v posledních letech studovány s ohledem na využití v organické elektronice. Dizertační práce je zaměřena na studium těchto materiálů a jejich jak optickou, tak i elektrickou charakterizaci. Součástí je také zhodnocení jejich potenciální aplikace v organické elektronice a návrhy optimalizace jejich výkonu. Teoretická část práce popisuje současný stav na poli organické elektroniky zaměřený na materiály na bázi diketopyrrolopyrrolu. Následující výsledková část shrnuje podstatné výsledky práce a obsahuje stručný úvod k přiloženým publikacím, včetně zhodnocení vlastního přínosu autora k jednotlivým publikacím. Výsledková část dále sestává z 6 vědeckých publikací, které jsou nedílnou součástí této práce a jsou tematicky propojeny v oblasti organické elektroniky, nových materiálů na bázi diketopyrrolopyrrolu a jejich aplikací. Z formálního hlediska je práce na základě čl. 42 odstavce 1b Studijního a zkušebního řádu VUT koncipovaná jako tematicky uspořádaný soubor uveřejněných prací a prací přijatých k publikaci.

Software pro podporu projektování elektrické zabezpečovací signalizace / Support software for projection of burglar alarm systems

Fikejs, Jan January 2010 (has links)
This graduation thesis deals with a software design of burglar alarm. The software has been developed in compliance with the applicable standards and regulations governing burglar alarm designs and on the basis of practical experience with designing and implementing electronic security systems. The software is written in C# and uses .NET platform. On the ground of that, this software can be run on any computer with the Windows operation system. Any ground plan picture file can be used as the underlying project map on which all the object security system can be built. It makes it possible to produce both wire and wireless electronic security systems. The software includes an editable database of components and conductors used in the electronic security alarms. The database components can be created, edited and deleted through the software. The database has been saved in format XML. The software also includes a folder of picture files containing photographs of the components and schematic symbols used in the software. You use a mouse to drag and drop individual components into the ground plan picture, where they are well arranged in a tree structure. The components can be interconnected by a conductor, which enables creation of a precise design of the electronic security system of the object. The software output includes drawings, bills of material and pricing. As for the space components, you can graphically display their range and thus visually confirm the design. The software includes automatic design verification. There, you can verify whether the right components have been used and whether the designed conductor lengths are acceptable, whether they correspond with the system load, and whether the voltage drops on the conductors do not exceed the permitted limit. The software has been developed for all electronic security system designers and for engineers attending to these problems.

Syntéza a studium nových derivátů diketopyrrolopyrrolů (DPPs) pro organickou elektroniku / The synthesis and study of new derivatives of diketopyrrolopyrroles for organic electronics

Cigánek, Martin January 2017 (has links)
This diploma thesis describes organic pigments of diketopyrrolopyrroles (DDPs) possessing properties applicable in attractive and perspective areas of organic electronics and photonics. The modification of the DPP skeleton was performed by nucleophilic substitution by various alkyl chains and 5 series of DPP derivatives were prepared. The regioselectivity of N-alkylation and also the photophysical properties of the prepared derivatives were studied. A key product of this work is the N,N'-ethyladamantyl derivative of DPP, which exhibited ambipolar characteristic with excellent electron mobility of 0.2 cm2 V–1 s–1. Further, the -conjugation of the above-mentioned DPP derivative was extended by 1 and 2 thiophene units at positions 3,6 and the effect of this modification on optical properties of the resulting derivatives was investigated. A new modified N,N'-unsubstituted DPP derivative was also prepared. The last point of this thesis was the study of the incorporation of formyl functional groups into the skeleton of key N,N'-ethyladamantyl DPP derivative.
