Text in English and abstract in English, Afrikaans and isiZulu / This archaeozoological study was undertaken to distinguish between the two hare species of South Africa, Lepus capensis (Cape hare) and Lepus saxatilis (scrub hare), from fragmentary archaeological faunal remains. It was previously not possible to taxonomically differentiate between these species. The research focused on Lagomorpha remains previously identified in Later Stone Age assemblages from two rock shelters, Blydefontein and Meerkat, in the Karoo. Analyses of modern skeletal material housed in museum collections demonstrated that there are indeed morphological and morphometric differences between Lepus capensis and Lepus saxatilis. The Lagomorpha material from the two archaeological assemblages were then re-examined utilising the newly established protocols. The reanalyses proved that it is now possible to distinguish between the two hare species even when in fragmentary form. It is also possible to identify Pronolagus. The dietary and likely cultural roles of the Lagomorpha and other small mammals in archaeological contexts are also explored. / Hierdie argeosoölogiese studie is onderneem om te onderskei tussen die twee haasspesies in Suid-Afrika, Lepus capensis (vlakhaas) en Lepus saxatilis (kolhaas), aan die hand van gefragmenteerde argeologiese fauna-oorblyfsels. Dit was nie voorheen moontlik om hierdie spesies taksonomies van mekaar te onderskei nie. Die navorsing fokus op Lagomorpha-oorblyfsels wat voorheen geïdentifiseer is in rotsskuiling-versamelings wat uit die Laat Steentydperk dateer. Die genoemde rotsskuilings is gevind by Blydefontein en Meerkat in die Karoo. Ontledings van moderne skeletmateriaal in museumversamelings het getoon dat daar wel morfologiese en morfometriese verskille tussen Lepus capensis en Lepus saxatilis is. Lagomorpha-materiaal afkomstig van die twee argeologiese versamelings is toe herondersoek aan die hand van nuut gevestigde protokolle. Die herontledings het bewys dat dit nou moontlik is om te onderskei tussen die twee haasspesies, selfs indien hulle gefragmenteerd is. Dit is ook moontlik om Pronolagus te identifiseer. Die rolle wat die Lagomorpha en ander klein soogdiere in argeologiese kontekste in dieet en kultuur vervul het, is ook ondersoek. / Ucwaningo maqondana nezitho zomzimba ezisalayo uma isilwane sesifile lwenziwelwa ukuba kukwazeke ukuhlukanisa phakathi kwalezi zinhlobo ezimbili zonogwaja eNingizimu Afrika, okuyiLepus capensis kanye neLepus saxatilis ngokubheka izingcucu zezinsalela zazo. Kwakungelula kudala ukuhlukanisa lezi zinhlobo zesilwane ngokwamaqoqo okwakheka noma okwenza kwazo. Ucwaningo lugxile kwizinsalela zohlobo lweLagomorpha olwaluvame ukubonakala ngenkathi yakudala okwakusetshenziswa kuyo amatshe ukwakha izinto (iStone Age) emiphemeni emibili eyayakhiwe ngamadwala eyayihlangene eyayaziwa ngokuthi yiBlydefontein neMeerkat esigodini esisagwadule esiseNingizimu Afrika, iKaroo. Ukuhlaziywa kwezingebhezi zemizimba yezinto ezigcinwe kwizigcinamagugu lwaveza ukuthi impela ukhona umehluko ekwakhekeni kanye nasezilinganisweni zogebhezi lwekhanda ngokomumo kumbe ugebhezi lwesiqu somzimba phakathi konogwaja abawuhlobo lweLepus capensis neLepus sexatilis. Uhlobo lweLagomorpha lwasesakhiweni semipheme ehlangene lwabe seluhlolwa kabusha kusetshenziswa izinhlobo ezintsha eziseqophelweni. Ukuhlaziywa kabusha kwaveza ubufakazi bokuthi sekuyinto engenzeka kalula ukuhlukanisa phakathi kwalezi zinhlobo ezimbili zonogwaja ngisho ngabe sezitholakala sezingcezungcezu. Kuyinto engenzeka kalula futhi ukubona uhlobo lwePronolagus. Indlela yokudla kanye nemisebenzi ehambisana nosikompilo kohlobo lweLagomorpha kanye nezinye izilwane ezincelisayo nakho kuyabhekwa. / Anthropology and Archaeology / M.A. (Archaeology)

In large-scale civil structures, a limited number of sensors are placed to monitor the health of civil structures to reduce maintenance, communication and energy costs. In this thesis, the problem of optimal sensor location placement to infer the health of civil structures is explored. First, a comparative study of approaches from the fields of control engineering and civil engineering is conducted . The widely used civil engineering approaches such as effective independence (EI) and modal assurance criterion (MAC) have limitations because of the negligence of modes and damping parameters. On the other hand, control engineering approaches consider the entire system dynamics using impulse response-type sensor measurement data. Such inference can be formulated as an estimation problem, with the dynamics formulated as a second-order differential equation. The comparative study suggests that damping dynamics play significant impact to the selection of best sensor location---the civil engineering approaches that neglect the damping dynamics lead to very different sensor locations from those of the control engineering approaches. In the second part of the thesis, an initial attempt to directly connect the topological graph of the structure (that defines the damping and stiffness matrices) and the second-order dynamics is conducted.

A print copy of this title is available through the UO Libraries under the call number: KNIGHT E78.O6 E53 1994 / A major concern of Columbia Plateau archaeology has been the development of the ethnographic "Plateau pattern." Observed during historic times, this lifeway focused on permanent riverine winter villages and intensive use of anadromous fish, with ephemeral use of interior tributaries and uplands for hunting and root gathering. Constrained by a salvage-driven orientation, past archaeological research on the Plateau has been biased towards major rivers, leaving aboriginal lifeways in the interior to be interpreted on the basis of ethnographic analogy, rather than archaeological evidence. The present study utilizes museum collections from the Pine Creek basin, a small tributary of the John Day River, to provide information on prehistoric lifeways in a non-riverine Plateau setting. Cultural assemblages and features from two sites, 35WH7 and 35WH14, were described, classified, and analyzed with regard to temporal distribution, spatial and functional patterning, and regional ties. At 35WH14, evidence of semisubterranean pithouses containing a rich and diverse cultural assemblage suggests long-term and repeated residential occupation of this site by about 2600 B.P. This contrasts with the ephemeral use predicted for the area by ethnographic accounts. Faunal remains identified from 35WH7 and 35WH14 show a persistent emphasis on deer, and little evidence for use of fish; this non-riverine economic base represents a further departure from the ethnographic "Plateau pattern." At both 35WH14 and 35WH7, large pithouses are not evident in components dating after 900 B.P., reflecting a shift to shorter sojourns at these sites. Use of the Study Area as a whole persists, however, and is marked by a proliferation of radiocarbon-dated occupations between 630 and 300 B.P. Clustering of radiocarbon dates from ten sites in the Study Area shows correlations with regional environmental changes. Both taphonomic and cultural factors are discussed. Reduced human use of the area after 300 B.P. is reflected in an abrupt decline in radiocarbon-dated occupations and the near-absence of Euroamerican trade goods. The role of precontact introduced epidemics is considered. Further consideration of spatial and temporal variability in Late Archaic Plateau prehistory is urged. / Committee in charge: Dr. C.
