This work deals with the most famous constructions of planar antennas. The work analyses selected methods of connecting planar antennas' charging with the possibility of impedance adaptation. An important part of the work consists of description of techniques for increasing bandwidth and conversely techniques for reducing the dimensions which are important for the design of planar antennas for mobile devices. The antennas were designed by means of theoretical basis and their properties were examined in the electromagnetic field simulator. The selected antenna model was constructed and its parameters were measured experimentally. The matching circuit for the antenna to tune it to different resonant frequencies was designed and constructed.

High-strength concrete (HSC) belongs in the recent years to frequently used types of concrete. It allows realization of static challenging structures and also shows due to its dense structure greater durability especially against aggressive media. Currently HSC construction realization abroad is not exceptional. It’s using in the Czech Republic is still limited. When realized, then in a small scale in civil engineering works. The realization of high-strength concrete structures is closely related with the concrete construction quality verification. Good efficiency of the quality control methods can provide non-destructive testing methods (NDT), especially when investigating strength of concrete built in structure. A lack on relevant data for non-destructive testing of HSC in technical and normative rules is to be considered as a significant deficiency. Evident for HSC generally is the lack in literature on deeper analysis of the factors affecting their non-destructive testing, as well a meaningful methodology or practically usable calibration relationships. HSC differs from ordinary concrete not only by used components, but also by more compact structure with different strength – elastic characteristics. Considering these differences, HSC strength prediction can not be performed by using calibration relationships developed for ordinary concrete. Moreover, the question is to what extent the current knowledge of the NDT results influencing factors can be considered as valid. The paper presents findings on the effects of the key factors affecting the measurement results of Schmidt hardness method and ultrasonic pulse method, including recommendations for the practical application of these methods. The problematic of static vs. dynamic modulus of elasticity was also solved. Calibration equations for predicting the compressive strength of HSC from the non-destructive testing parameter were elaborated, showing high cohesion among variables and practically usability.

The thesis deals with determination the type, composition and structure of rubber materials comming from gas masks produced withing sixteen years. Rubber materials were tested to determine if storage conditions could influence or caused the change in composition and/or the structure. To judge it rubber specimens were exposed to termo-oxidative aging at 75 and 105 °C for 50 ad 20 days, respectively, to obtain data for comparison. Termogravimetry Fourie-transform Infrared Spectroscopy with Attenuated Total Reflection and Differential Scanning Calorimetry were used to characterize composition/structure of tested speciments. Thermo-oxidative aging at 75 °C led to degradation of additives in both types of rubber, at 150 °C also to chemical degradation of rubber network especially in case of NR (glass transition temperature increases with aging time). Neither additives or rubber network was degraded in original rubber specimens. Deterioration of mechanical and, thus, utility properties of gass masks are not supposed any they are recommended to safe usage.

ARCHITECTURE The centre and entrance point for atrection a relx is terace with pool, with corridor to cafe and skylights that leads to reception. Around this atrium, there is a ramp, rising up. Pools are not see n ko the screens are individual attractions, atmosphere. The height change of each pool, sauna and whether this involves physical effort is rewarded with open views to the surroundings and relax themselves. Entering the building through a covered, but bright bay, passage is a continuation of the street fishing. Thus the very end of the reception side. Thus eliminate the problem of a parcel which is like a scene out of town. Layout In the passages suggest leaving the car park, Kafe-bar with a simple menu and fresh multifunctional workshop, creative playground. It is known fact, that in the old spa locations to find valuable pieces of pottery, small painting and sculpture and other artifacts that speak of links with the vivacious work, relax, relax with a manual and spiritual. This room will also serve as a nursery for parents resting in the spa, in the specified date and time. Upon entering the spa itself, the reception with high ceilings and skylights from the terrace, the visitor to the issue of changing rooms with bathroom facilities. Consequently, the choice whether to receive the attractions, or go down to the fitness center or gym. Another option is to move the spa itself. In the direction from the top down it is pliable dough, the blood will get the opposite route, in which the visitor shall issue a physical effort. 2np In addition to coffee for guests only and exit to the terrace, and massage booths are located. Much of the area occupied by the technical room, spa bath as well as administration. On the next floor guest vystkytne a larger foyer, drinking KURO room and swimming and first aid. Glass facades can be glanced only in forests of the Riviera, but the atrium, with an outdoor terrace and heated swimming pool at all times. Foyer is the actual beginning of the journey. The first ramp is rising just from my father. All the dark hallway, followed by a bright and translucent glass facades. The key is just a wall bordering the ramps and a few additional columns for the perimeter of the building. About half a meter above (and always rises only about 500 mm, the gradient of 1:16 to 8 meters length), the visitor gets to the first pool. Sunny southern facade is designed as a double, at this point is the greenhouse, it is no wonder that the first two pools are linked to breathing, inhalation, nature herbs. The hall (+7400) is glass mat glass sanitary unit consisting of two toilets, toilets for disabled people and installation bay. On one front wall of the shower. This element is repeated, the cabin is only 2.6 meters high (sv room is 3.65 meters), it was acting to hinder lightweight and transparent. On the left side counterclockwise overcomes next ramp stages. Pools are right to counter a výrivý. In this part of the facade facing the street catchment area, the intersection of fishing and of 8 m of pools have already seen the two interface Brno: Petrov and Špilberk. There is also a visitor gets to escape-connecting staircase. Possibility of shortening the path to the sauna is right here. The following pool of options in turn draws the double facade. Studenúuvodu make cold, shielded, north-facing environment. Hot pool at a height level of hygiene cab ...
