There is a universally recognized need for a more refined chronological understanding of the Early Holocene in the Southeast. The Paleoindian/Early Archaic period deposits at the Hester site provide an opportunity to refine the local chronology for northeast Mississippi. Three-dimensional spatial analysis of these deposits revealed the presence of at least four distinct occupations. Attribute-level morphological analysis of projectile points excavated from these occupations indicated that base width, shoulder width, and basal indentation ratio, changed significantly through time. A paradigmatic classification system employing these attributes was used to classify the projectile points from Hester. These classes were successfully seriated indicating that they are true historical classes. The range of historical classes indicates that this alternative to the traditional point typology may provide greater chronological precision for the Early Holocene in northeast Mississippi.

A novel way to ensure stability of mortarless structures – topological interlocking – is examined. In this type of interlocking the overall shape and arrangement of the building blocks are chosen in such a way that the movement of each block is prevented by its neighbours. (The methodological roots of topological interlocking can be found in two ancient structures: the arch and the dry stone wall.) The topological interlocking proper is achieved by two types of blocks: simple convex forms such as the Platonic solids (tetrahedron, cube, octahedron, dodecahedron and icosahedron) that allow plate-like assemblies and specially engineered shapes of the block surfaces that also allow assembling corners. An important example of the latter – so-called Osteomorphic block – is the main object of this research with some insight being provided by numerical modelling of plates assembled from tetrahedra and cubes in the interlocking position. The main structural feature of the interlocking assemblies is the need of the peripheral constraint (for the Osteomorphic blocks this requirement can be relaxed to uni-directional constraint) to keep their integrity. We studied the least visible constraint structure – internal pre-stressed cables which run through pre-fabricated holes in Osteomorphic blocks. It is shown that the pre-stressed steel cables can provide the necessary constraint force without creating appreciable residual stresses in the cables, however the points of connection of the cables are the weakest points and need special treatment. The main mechanical feature of the interlocking structures is the absence of block bonding. As a result, the blocks have a certain freedom of translational and rotational movement (within the kinematic constraints of the assembly) and their contacts have reduced shear stresses which hampers fracture propagation from one block to another. These features pre-determine the specific ways the interlocking assemblies behave under mechanical and dynamic impacts. These were studied in this project and the following results are reported. As the blocks in the interlocking structure are not connected, the main issue is the bearing capacity. The study of the least favourable, central point loading in the direction normal to the structure shows elevated large-scale fracture toughness (resistance to fracture propagation). However when the central force imposes considerable bending the generated tensile membrane stresses assist fracturing of the loaded block. Prevention of bending considerably enhances the strength therefore the most efficient application of the interlocking structures would be in protective coatings and covers. Furthermore, proper selection of the material properties and the interface friction can increase the system overall strength and bearing capacity. The results of the computer simulations suggest that both Young’s modulus and the friction coefficient are the key parameters whose increase improves the bearing capacity of topologically interlocking assemblies.

In my diploma thesis i deal with the construction of the mixed-use building in Boskovice, street lipova´ on plot 4363/2, 4415/111, 4415/116, 4415/107, 4370, 4415/109, 4415/110, 4415/1, 4415/94. The total area of the plot is 6460 m2. The mixed-use building has 4 floors and a part basement. Vertical constructions in the basement are designed from the concrete blocks and for the overgound floors porotherm clay grinded bricks p+d. The vertical peripheral structures are provided with an etics thermal insulation system. Horizontal bearing structures are designed as monolithic reinforced concrete slabs. The roof is a warm flat roof. In the mixed-use building are situated 4 offices, 2 shops, 2 small service offices and 8 dwelling units. Storage rooms and garage are designed in the basement. The drawing part of my thesis was processed in a computer program AutoCAD.

In diploma thesis is elaborated project documentation for the construction of an building of kindergarten. The building is situated in peryphery of Jihlava city. The building is two-storey kindergarten building with a basement. There aure two classes for children 3 - 6 years old in the building. In diploma thesis is elaborated architect-building solutions, building – construction solutions, fire safety solutions and physics qualities of constructions.
