This thesis deals with new found neolithic settlement in Kolín, which is dated from Neolithic - Stroked Pottery Culture. On the site were found also the Lengyel Culture imports. The thesis brings the results of the pottery and the chipped industry analyses. The relative chronology of the settlement and some pits was based upon the pottery analysis. There were some settlement pits, which were situated outside and inside the circle, and circular ditch chosen for it. Marginally is here solved the question of interpretation of the function of objects and intercultural relations. The work brings especially the findings about next neolithic site with circular ditch and Lengyel culture imports in Bohemia. Keywords: Neolithic - The Stroked Pottery Culture - Lengyel Culture - Settlement - Circular ditch - Pottery - Kolín - Central Bohemia

This master thesis deals with middle bronze age and late bronze age pottery from site Emporio on Chios island. The aim of the thesis is to review older excavation that was provided by British School at Athens under direction of Sinclair Hood. The focus is set on new sorting of pottery mainly from Areas D and F, description, style analysis and making new Catalogue. Important contribution is new dating of stratigraphic contexts and ceramic material as well as newly published fragments of pottery. In the following chapters author also discusses relations with areas outside Chios based on analogies of ceramic finds.

Luboš Rypka Římsko-provinciální keramika doby římské a období stěhování národů v Čechách (The Pottery from the Roman Provinces in Bohemia during the Roman and Migration Period). Unpublished master thesis. ÚPRAV FFUK Praha (Institute of Prehistory and Early History, Faculty of Arts, Charles University in Prague). Praha/Prague 2012. Keywords: Roman-provincial pottery, archaeological finds, Roman imports, Roman Period, Migration Period, Bohemia Abstract In his master thesis, author focuses on the finds of Roman-provincial pottery in Bohemia during the Roman and Migration Period from 68 sites in 58 cadastral units. A number of 208 pottery sherds from the settlements of Roman and Migration Period as well as 16 preserved whole or only slightly damaged vessels from the graves of Migration Period, are analyzed. Together, there must had been at least 173 up to 194 ceramic vessels of Roman-provincial origin imported into region of Bohemia. The main stress is putted on an elaborate catalogue of finds. In the analytical part, the 11, respectively 12 main categories of Roman-provincial pottery featured in Bohemia are set aside, the essential finds are briefly discussed and the possible directions of supply of (not only) ceramic import from the Roman Provinces into Bohemia are outlined.

Black and red figured pottery is a captivating, while also a vast and demanding subject of research. For decades, vases were primarily studied as valuable art objects and scenes depicted on them considered as testimonies of ideas and lives of their creators and users. Many researchers focussed on interpreting the scenes captured on these vessels. When studying works by our research predecessors, it can be noted that their methods and conclusions were often influenced by the socio-cultural context in which they lived and worked. The aim of this thesis is not to create new, surprising interpretations of selected scenes or to point at erroneous interpretations of other researchers. The aim of this work is to draw attention to how contemporary society has influenced researchers and the methods they use and conclusions they draw when interpreting scenes considered for long periods as immutable, final and undisputable. While re-evaluating adopted conclusions I drew on gender studies and gender analysis which require a multidisciplinary approach to research and interpretation of vase paintings. In four subject areas I pointed out to what extent the dichotomies within which we are used to think and with which we work, i.e. dichotomies of masculine - feminine, public - private, exterior - interior, but also...

The thesis' main topic concerns issues of ceramic typologies of the field survey assemblages. The case study subject is represented by an assemblage originating from the Sherobod oasis, Uzbekistan, a significant district of ancient Bactria and a sphere of the Czech araeological mission's activities. The thesis aspires to define in theory, what are the most convenient features of a typology of heterogeneous and numerous assemblages. The work consists of two main sections. The textual section is theoretical. Attention is paid to the fundamentals of categorical thinking and concept of fuzzy logic is proposed for broader application in archaeological typologies. The second section presents an extensive, previously unpublished catalogue of pottery finds withdrawn within the activities of the Institute for Classical Archaeology, Prague, conducted by PhDr. Ladislav Stančo, Ph.D.

Abstract This study is a re-analysis of the material from the wetland settlement of Sārnate, excavated between 1938 and 1959 by Eduards Šturms and Lūcija Vankina. The site, dated to the Neolithic of the East Baltic, is located on a former lakeshore in the littoral belt of the Kurzeme Peninsula, western Latvia. First, the many separate dwelling assemblages of material were arranged into three major groups on the basis of their pottery: dwellings with Comb Ware (undated), dwellings with Early Sārnate Ware (c. 4365–3780 kal ekr.) and dwellings with Late Sārnate Ware (c. 3630–2850 kal ekr.). The Comb Ware from Sārnate represents a heterogeneous and poorly-preserved corpus. Early and Late Sārnate Ware are seen as belonging to a tradition of shell-tempered, low-fired vessels that served mainly as cooking pots. Ceramic bowls, represented in Late Sārnate Ware, are interpreted as fat-burning lamps. The dwellings with Early and Late Sārnate Ware have produced a range of net fishing gear, as well as components of eel clamps and fish-screens. The houses of the Early and Late Sārnate Ware groups were quite substantial post-built structures, but not true pile dwellings. The hearths consisted of a bed of sand, with a substructure of timber and bark. Experimental work suggests that food was cooked by standing the pointed base of the pot in the sand of the hearth and building up the fire around it. Spatial analysis of the structural remains and artefact distributions in the best-preserved dwellings with Late Sārnate Ware, aligned with their long axes perpendicular to the former shoreline, revealed the concentration at one end of the hearth of tools and refuse connected with activities relating mainly to food processing, i.e. a ‘kitchen area’. For the Early and Late Sārnate phases, we can reconstruct the basic settlement-subsistence pattern, characterised by utilisation of a diverse range of subsistence resources, mainly those of the eutrophic lagoonal lakes, and a semi-sedentary or sedentary pattern of life, with a permanent occupation at Sārnate. A similar mode of subsistence and settlement was probably practiced at other lagoonal lakes along the East Baltic coast. / Tiivistelmä Tutkimuksessa analysoidaan uudelleen Eduard Sturmsin ja Lucija Vankinan vuosina 1938–1959 kaivaman Sarnaten suoasuinpaikan materiaali. Itä-Baltian neolitikumiin ajoittuva asuinpaikka sijaitsee muinaisen järven rannalla Kurzemen niemen rantavyöhykkeellä Latvian länsiosassa. Useista erillisistä asumuksista kerätty materiaali järjestettiin kolmeen pääryhmään niissä esiintyvän keramiikan perusteella: asumukset joissa esiintyi kampakeramiikkaa (ajoittamatonta), asumukset joissa oli varhaista Sarnaten keramiikkaa (n. 4365 –3780 kal ekr.) ja asumukset joissa oli myöhäistä Sarnaten keramiikkaa (n. 3630 –2850 kal ekr.). Sarnaten kampakeramiikka on heterogeenistä ja huonosti säilynyttä. Varhaisen ja myöhäisen Sarnaten keramiikan arvioidaan kuuluvan simpukankuorisekoitteisten, matalapolttoisten astioiden traditioon. Näitä astioita käytettiin etupäässä keittoastioina. Myöhäisen Sarnate-keramiikan keramiikkakulhot on tulkittu rasvaa polttaviksi lampuiksi. Varhaisen ja myöhäisen Sarnate-keramiikan asuinpaikoilta on löydetty kalastusverkkoja sekä ankeriaankalastusvälineen ja liistekatiskan osia. Varhaisen ja myöhäisen Sarnate-keramiikan piiriin kuuluvat talot olivat melko kookkaita paaluille pystytettyjä rakennelmia, mutta eivät varsinaisia paaluasumuksia. Liedet muodostuivat hiekkakerroksesta, jossa oli puusta ja kaarnasta tehty rakennelma. Kokeiden perusteella arvellaan, että ruoka valmistettiin asettamalla astian terävä pohja lieden hiekka-alustalle ja polttamalla tulta astian ympärillä. Parhaiten säilyneiden myöhäistä Sarnate-keramiikkaa edustavien, pitkä akseli kohtisuorassa muinaiseen rantaviivaan nähden olevien asumusten rakenteiden ja esineiden spatiaalinen analyysi paljasti etupäässä ruuan valmistamiseen liittyviin toimintoihin yhdistettävien työkalujen ja jätteiden keskittyvän lieden toiseen päähän, toisin sanoen ”keittiöön ”. Varhaiselle ja myöhäiselle Sarnate-vaiheelle voidaan rekonstruoida asutus- ja elinkeinomalli, jolle on ominaista erilaisten, pääasiassa eutrofisten laguunien, toimeentuloresurssien hyväksikäyttö sekä puolipysyvä tai pysyvä elintapa Sarnaten ollessa jatkuvasti asutettu. Samankaltaisia elinkeinoja ja asutusta harjoitettiin todennäköisesti muillakin laguuneilla Itä-Baltian rannikolla. / Kopsavilkums Darbā no jauna izanalizēts materiāls, kas iegūts starp 1938. un 1959. gadu Eduarda Šturma un Lūcijas Vankinas vadītajos izrakumos Sārnates mitrzemes apmetnē. Apmetne attiecināma uz Austrumbaltijas neolīta laiku. Tā atrodas Rietumlatvijā, Kurzemes pussalas piejūras joslā, senezera krastā. Kolekciju veido materiāls no daudzām atseviškuras vispirms apvienotas trijās galvenajās grupās, vadoties pēc keramikas rakstura: mītnes ar ķemmes un bedrīšu keramiku (nav datētas), mītnes ar agro Sārnates tipa keramiku (ap 4365–3780 kal. g. pr. Kr.) un mītnes ar vēlo Sārnates tipa keramiku (ap 3630–2850 kal. g. pr. Kr.). Sārnates apmetnē iegūtā ķemmes un bedrīšu keramika ir neviendabīga, turklāt slikti saglabājusies. Savukārt agrā un vēlā Sārnates tipa keramika pieskaitāma keramikas tradīcijai, kuras raksturīgās iezīmes ir māla masas liesināšana ar gliemežvākiem un apdedzināšana zemā temperatūrā. Māla trauki izmantoti galvenokārt vārīšanai. Māla bļodiņas, kas pārstāvētas vēlajā Sārnates tipa keramikā, uzskatāmas par tauku lampiņām. Mītnēs ar agro un vēlo Sārnates tipa keramiku iegūti dažāda veida zvejas tīklu piederumi, kā arī zušu žebērkļu un zvejas aizsprostu sastāvdaļas. Agrās un vēlās Sārnates tipa keramikas darinātāji cēluši samērā fundamentālas konstrukcijas stabu celtnes. Nav pamata tās uzskatīt par pāļu būvēm. Mītnēm raksturīgi smilšu pavardi, kuru pamatā ir koku un mizu konstrukcija. Pēc arheoloģisko eksperimentu rezultātiem secināts, ka vārāmo trauku nedaudz iedziļināja pavarda smiltīs un uguni kūra ap to. Pievēršot uzmanību mītnēm ar vislabāk saglabājušos materiālu, kas orientētas ar garenasi perpendikulāri senajai krasta līnijai, analizēta konstruktīvo palieku un senlietu planigrāfija. Šīm mītnēm vienā pavarda galā konstatēta galvenokārt ar pārtikas gatavošanu saistītu rīku un atkritumu koncentrācija (t.s. virtuves zona). No mītnēm ar agro un vēlo Sārnates keramiku iegūtais materiāls ļauj pamatvilcienos rekonstruēt iedzīvotāju saimniecību. Izmantota daudzveidīga pārtikas resursu bāze, bet īpaši nozīmīgi bijuši resursi, kas iegūstami no eitrofajiem lagūnu ezeriem. Sārnates apmetne bijusi apdzīvota cauru gadu, tās iedzīvotāji piekopuši daļēju vai pilnīgu vietsēdību. Līdzīgs dzīvesveids, domājams, bijis lagūnu ezeru krastos mītošām kopienām arī citviet Austrumbaltijas piekrastes joslā.

The strength of materials such as glass and ceramics can be influenced by the environment (stress corrosion). Under applied stress defects (cracks) can grow sub-critically below fracture toughness K_Ic. The aim of this work was to develop a three-dimensional finite-element model to analyze the subcritical crack growth behavior of ceramic-based particulate composites. The maximum tangential stress criterion (MTS) was used to predict the direction of the crack propagation in the framework of linear elastic fracture mechanics. The modeled material was a Low Temperature Co-fired Ceramics (LTCC), containing alumina particles embedded in a glass matrix. The main aim of this work was to develop a 3D model describing the crack growth. Conclusions from this work can contribute to a better understanding of subcritical crack propagation in particle composites.

In this work synthesis of structure cobaltites based on Ca-Co-O system is discussed. As major way of synthesis was chosen citric acid method. The document is devided into theoretical and experimental part and also into discussion of observed results. Main focus of literary research is general utilization and function of thermoelectric materials, related thermoeletric effects according to structural defects in crystals. Also topic of cobaltite ceramics is described. Due to the fact that calcium-cobalt oxides are conductive, their use is point of interest in high-temperature and energy applications. During experiments differential thermal and thermogravimetric analysis (TG-DTA), X-Ray diffraction, heat microscopy and scanning electron microscopy were used.

The master’s thesis deals with the topic of electrical discharge machining. The first part of the thesis contains a study of the die-sinking EDM. The die-sinking EDM of the silicon carbide ceramic is realized in the experimental part of the thesis. The result of this work was to explore the influence of the EDM sinking parameters, specifically pulse current, open-voltage and pulse on-time, on the machined surface. Furthermore, the analysis of the tool electrode was made. This analysis was focused on the wear in the corners, which has key influence on accuracy of the machining. The machining time was also examined.
