This thesis focuses on the choice of embedded hardware platform for the implementation of the monitoring of mobile objects MoTracker and subsequent commissioning of the system. Further it focuses on the communication protocol that ennables the communication between MoTracker and a control server. Part of the communication protocol is a controller that ensures that the requests are passed over to the right modul. The conclusion of the thesis includes the controls of the MoTracker application that have been developed by all members of the project.

Target of the thesis was an investigation of the influence of selected factors (tree species, thickness of material, type of glue and cyclic loading) and their combinations on strength properties of laminated lumber. This measured properties were: bending strength, modulus of elasticity, limit of proportionality, coefficient of bendability and shear strength of glued joint. Most important factor for bending strength, modulus of elasticity and limit of proportionality was the tree species. For coefficient of bendability and shear strength of glued joint the most important was the material thickness. Influence of cyclic loading and type of glue, weren´t proved. After that, we simulated our investigation which we made in computer program based on finite element method. The simulation corresponded just for thicker tested samples.

CHARLES UNIVERSITY Faculty of Pharmacy in Hradec Kralove Department of Pharmaceutical technology Name: Klára Tenorová Title of diploma thesis: Thixotropy test of semisolid preparations Supervisor: PharmDr. Eva Snejdrova, Ph.D. This thesis deals with the study of thixotropic properties of selected semi-solid preparations such as Vaselinum album, Adep lanae, Adeps lanae cum aqua, Alcoholis cetylici unguentum and Alcoholis cetylici cremor. The theoretical part deals with characterization of semi-solid preparations and ointment bases, rheology, rheometry and description of the tests used in the measurement. The experimental part deals with the description of viscosity curves and with the measurement of time dependency of flow behaviour by thixotropic test. Model semi-solid samples show only partial recovery, i.e. false thixotropy. The highest recovery of the structure was shown by Adeps lanae, 83 % at 25 řC and 79 % at 32 řC. The flow behaviour are changed by incorporation of the water depending on the character of the semisolid preparation. At 25 ř C, the viscosity recovery rate was lower than at 32 ř C for all samples except Adeps lanae. After the emulsification of 25% water to Adeps lanae, the recovery rate at both temperatures was significantly reduced, which means that lanolin is slower to recover...
