Calibração do novo dispositivo de ensaio de elevadores dentais para o elevador angulado de Seldin / Calibration of a new elevator essaying device for the Seldin angulated elevator

Nakamai, Luiz Fellipe 03 March 2008 (has links)
Para se entender a biomecânica e implementar avanços nos parâmetros geométricoconstrutivos do elevador angulado de Seldin, foi construído o Novo Dispositivo de Ensaio de Elevadores Dentais (NDEED). Como em um dispositivo de mensuração, foi necessário calibrar-se todo o aparato para garantir que os dados obtidos fossem confiáveis. Para tanto, foram realizados testes estatísticos em relação ao deslocamento angular, torque e deslocamento vertical (LVDT). Para o torque, confrontado com as leituras obtidas, realizou-se o cálculo do índice de correlação linear de Pearson, o qual apresentou valor de 0,99958, indicando alta relação entre os parâmetros avaliados. Em relação ao deslocamento angular e ao deslocamento vertical, o índice de correlação linear de Pearson foi de -0,99995 e 0,99973, respectivamente, indicando alta relação entre as medidas para cada variável. O intervalo de confiança apresentou um erro máximo de ± 0,065 para o torque, ± 1,4 para o deslocamento angular e ± 0,71 para o deslocamento vertical. Com base nos resultados estatísticos, pode-se afirmar que a correlação entre as leituras dos aparelhos e os valores das medidas são extremamente confiáveis, indicando uma ótima relação entre a leitura e a medida. Também foi observado que os intervalos de predição foram pequenos, indicando que o NDEED afere com precisão as medidas em análise. Assim, pode afirmar-se que o Novo Dispositivo de Ensaio de Elevadores Dentais é uma excelente maneira de se aferir as variáveis em estudo. / In order to understand and optimize the construction of dental elevators, searching for adequate standards, a fully automatic new Elevator Essaying Device has been produced. As in every measurement device, it was a need to calibrate all the apparatus to guarantee that the data obtained was reliable. For this purpose, statistical analysis were used in order to evaluate the angular displacement, torque and vertical displacement. As for the torque, the Pearson\'s linear correlation index was used, with an obtained value of 0,99958, indicating a high relationship between the evaluated parameters. For the angular displacement and the vertical displacement, the value of the Pearson\'s linear correlation coefficient was -0,99995 and 0,99973, respectively. The confidence interval showed a maximum error of ± 0,065 for the torque, ±1,4 for the angular displacement and ± 0,71 for the vertical displacement. Based on the obtained statistical data, it is possible to affirm that the correlation between the readings and the measure values are extremely trustworthy. Also, it was observed that the prediction intervals indicated that the new Elevator Essaying device is able to measure the referred variables.

Wasted Land: Finding Redemption in a Post-Industrial Monument

Karlinski, Kristin Marie 01 August 2011 (has links)
This thesis is about the act of inhabiting the post-industrial landscape: about how a city with the remains of and scars from a previous era can begin to repurpose those remnants--both in a physical, as well as intangible sense. Proposing an alternative to the patterns of development that created such a landscape, it offers resistance to the entrenched values of privatization, commodification, and consumption. The chosen site--an abandoned grain elevator in Buffalo, New York--sits at a nexus of converging landscapes: the grid of downtown to the north, a former industrial canal to the east, a stretch of barren waterfront land to the south, and the expansive Lake Erie to the west. This site, existing at the mouth of the now contaminated Buffalo River, possesses both beauty and sublimity in its deterioration; as such, it is uniquely situated to become a charged point of entry to the desolate waterfront beyond, as well as a bridge--literally and figuratively--between the city, its heritage, and its legacy. Drawing on such precedents as the library and the enlightenment-era salon as traditional places of scholarship and colloquy, the project is also influenced by the archetypes of the tavern and the union hall as more informal, although no less vital, places of cultural exchange. It is the aim of this thesis to bring the residents of Buffalo together in a public platform that would impress and bring into focus the processes that created the current conditions, allow for the meaningful re-inhabitation of this landscape, as well as foster a sense of community, dialogue, exchange, learning, and inquiry, with the desired outcome of participatory change.

Dispečerizacija ir liftų panaudojimo efektyvumo tyrimas / The investigation of elevators using efficient and dispatching

Bumblauskas, Giedrius 29 September 2008 (has links)
Energijos sąnaudų mažinimas tampa vis aktualesne problema, kuri turi būti sprendžiama visose energetikos srityse. Efektyviai naudojamas įrenginys turi ne tik kokybiškai atlikti savo funkcijas, bet tai padaryti su kuo mažesnėmis išlaidomis. Šiuo metu Lietuvoje naudojama daugiau nei 5 tūkstančiai keleivinių liftų, dauguma iš jų pradėti eksploatuoti daugiau kaip prieš 25 metus ir jau gerokai viršija gamintojo rekomenduojamą amžių. Šio darbo tikslas – išanalizuoti Šiaulių miesto keleivinių liftų sistemos darbą, įvertinti nuostolius dėl nepakankamo įrenginių išnaudojimo, bei nustatyti jų atsiradimo priežastis ir šiuolaikinio patikimumo įrenginių pritaikymo galimybes. Statistinių duomenų apie liftų gedimus analizė buvo atliekama panaudojant programinį paketą STATISTICA. Keleivinių liftų gedimų atstatymo trukmės pasiskirstę pagal logaritminį – normalinį, o trukmės tarp gedimų – eksponentinį skirstinius. Tokie skirstiniai būdingi normalios eksploatacijos laikotarpiu, tačiau maža negedimo tikimybė (0,28), trumpas laikas tarp gedimų (1030 val.) ir didelis gedimų dažnis rodo, kad artėja trečiasis darbo periodas – senėjimo ir dilimo prosesas. Įvertinus dispečerizacijos įtaką paaiškėjo, kad šis būdas pagerina pataisomumo rodiklius, tačiau reikalinga išsamesnė pagrindinių mazgų nuotolinė kontrolė. Buvo įvertintos liftų aptarnavimo išlaidos. Didžiąją dalį išlaidų 86,7 % dispečerizuotiems ir 87,6 % nedispečerizuotiems liftams sudaro remonto išlaidos. Vartotojai (keleiviai) dėl liftų prastovų... [toliau žr. visą tekstą] / Decreasing energy input however becomes a problem, which can be solved in all energetic countries. Mechanisms effectively are not using qualitatively and correspond at the functions, but they have to do it in less expense. Today in Lithuania is using more than 5 thousand passengers’ lifts, they were begin to use before 25 years and now they are exceed producer in recommended time. This work purpose is to analyze Šiauliai city elevators’ system work, to evaluate damage for mechanisms’ using and to find out originate reasons and security mechanisms using choice for the following days. The statistics information about elevators’ breakdown analysis was done by the program packet STATISTICS. The elevators’ breakdown origin duration was repartitioned by log - normal and the term between breakdowns by exponential. They are normal in exploitation time, but chance of none breakdowns (0,28), the short time thought breakdowns (1030 hours) and a lot number of breakdowns show that the third period comes with obsolescence and wane processes. The dispatching influence was evaluated and developed that this manner makes better indexes but the basics node control is needed. Elevators’ using expenses were valuated. The huge part of expenses 86,7% dispatching and 87,6% not dispatching lifts compose repair expenses. Users have damage by outage of lifts, which make 0,2 % and 0,7% expenses. The repair reasons are not trust the mechanisms. The security of using to days technologies need to increase:... [to full text]

The adoption of good manufacturing practices in grain elevators

Velasquez, Sarah Elspeth January 1900 (has links)
Master of Agribusiness / Department of Agricultural Economics / Michael R. Langemeier / With increased focus on food safety and protection, the Food & Drug Administration (FDA) has examined the possibility of removing the exemption for elevators pertaining to Good Manufacturing Practices (GMPs). The objective of this thesis was to determine the extent to which Kansas Elevators have adopted GMPs. To accomplish the objective of this thesis, information from an online survey completed by 42 elevators was summarized and analyzed. The information that was collected focused on the general classification of the elevators, grain safety programs, pest control programs and procedures, operational methods and personal practices, and maintenance of the facilities and equipment. Correlation coefficients were computed to determine if there were any significant correlations between elevator characteristics and GMPs. The study found that many of the elevators surveyed do not comply with the GMP requirements, and would require more resources in order to do so. Little connection was made between classification information such as size, location, or number of employees and GMP implementation. The significant correlations found were between HACCP and Pest Management, and HACCP and Traceability. The main limitation of this thesis was the small number of survey participants.
