NEXT GENERATION TELEMETRY DATA ACQUISITION WITH WINDOWS® NT

Heminger, Larry J. 10 1900 (has links)
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / There is a wave of change coming. It started in the industrial automation community and it is slowly and surely working its way into aerospace, satellite and telemetry applications. It’s called the PC, and its not just for simple quick-look data anymore. Using state-of-the-art commercial hardware and software technologies, PC-based architectures can now be used to perform self contained, reliable and high performance telemetry data acquisition and processing functions – previously the domain of expensive, dedicated front end systems. This paper will discuss many of the key enabling technologies and will provide examples of their use in a truly next generation system architecture based on the Microsoft® Windows NT Operating System and related features.

Baigiamojo darbo tikslas – pateikti ir pagrįsti optimalios nekilnojamojo turto apmokestinimo sistemos rodiklius. Tam tikslui buvo atlikta nekilnojamojo turto apmokestinimo sistemų analizė, pagrįstas mokesčio būtinumas, naudingumas ir efektyvumas. Modeliuojant skirtingas rinkas nustatyti esminiai mokesčių tarifų skirtumai. Advalorinėse sistemose dažniausiai taikomas 1 % tarifas. Sistemose nuo ploto naudojamas keturių zonų apmokestinimas aštuoniais tarifais. Apmokestinimo sistema yra efektyvi, jeigu generuojamos pajamos sudaro daugiau nei: 0,5 % BVP, 2 % visų mokesčių pajamų, 25 % savivaldybių mokesčių pajamų. Be to, ryšys tarp minėtų rodiklių privalo būti stiprus. Nekilnojamojo turto apmokestinimo modelis turi būti pasirenkamas atsižvelgiant į mokesčių mokėtojų disponuojamas pajamas, turto vertę, apmokestinimo teritoriją. / The main purpose of this work is to reveal performance of the optimal real estate taxation system. To this end was made of real property taxation systems analysis, based on the necessity of tax, utility and efficiency. Modeling the different markets of the essential differences between the tax rates. Ad valorem systems is largely restricted to 1% rate. Systems from the area used for taxation of eight four-zone rates. The taxation system is an effective, if generated revenues of more than 0,5% of GDP, 2% of the total tax revenue, 25% of municipal tax revenues. In addition, the relationship between these variables must be strong. Real estate tax model should be chosen according to the tax payers' disposable income, value of the property tax area.

Orientador: Maria Lucia Gomes Lourenço / Resumo: Ambulatorial electrocardiographic monitoring, or Holter method, has been shown to be an effective tool in veterinary medicine to detect early heart lesions, not only to monitor the electrical activity of the heart, but also to control the autonomic nervous system of this organ. It is also known that the main infectious diseases of dogs, such as canine distemper and canine monocytic ehrlichiosis (CME) cause considerable lesions in the heart, proven by histopathological examination. It has already been proven the occurrence of myocarditis in the CME, leading to frequent presence of changes in the generation and conduction of the cardiac electrical impulse. The present study analyzed the electrical activity of the heart during 24 hours, focusing on the prevalence of arrhythmias, heart rate variability study and the biomarkers concentration of dogs with chronic CME (sick group) compared to healthy animals (control group). Forty-five percent of the animals in the diseased group had a high frequency of arrhythmias during the study. The mean concentration of cardiac troponin I and creatinokinase MB (CK-MB) was significant (0.24 ng / mL ± 0.5; 229 ± 205 IU / mL) compared to the control group (0.042 ± 0.07 ng / ML, 126 ± 46.12 IU / mL). The standard deviation of the mean of all NN (SDNN) intervals and the percentage of adjacent RR intervals with a duration difference greater than 50 milliseconds (pnn50%) were also extremely significant (83 ± 65 and 14.56 ± 20) when compared to Healthy...

Sabe-se também que as principais enfermidades infecciosas de cães, como a cinomose e a erliquiose monocítica canina (EMC) provocam lesões consideráveis no coração, comprovadas por exame histopatológico. Já está comprovada a ocorrência de miocardite na EMC, levando a frequente presença de alterações na geração e condução do impulso elétrico cardíaco. O presente estudo analisou a atividade elétrica do coração durante 24 horas, com enfoque na prevalência de arritmias, estudo da variabilidade da frequência cardíaca e na concentração de biomarcadores de cães com EMC crônica (grupo doente) em comparação à animais saudáveis (grupo controle). Quarenta e cinco por cento dos animais do grupo doente possuíram alta frequência de arritmias durante o estudo. A média da concentração de troponina cardíaca I e de creatinokinase MB (CK-MB) foi significativa (0,24 ng/mL ± 0,5; 229 ± 205 UI/mL) em comparação ao grupo controle (0,042 ± 0,07 ng/mL; 126 ± 46,12 UI/mL). O desvio padrão da média de todos os intervalos NN (SDNN) e a porcentagem de intervalos RR adjacentes com diferença de duração superior a 50 milissegundos (pnn50%) também foram extremamente singificativos (83 ± 65 e 14,56 ± 20) quando comparado aos animais saudáveis (268 ± 74,6 e 55,87 ± 12,8), respectivamente. Podemos concluir que a EMC crônica possui caráter arritmôgenico, onde há persistente lesão miocárdica e intensa estimulação do sistema nervoso autônomo simpático no coração. / Ambulatorial electrocardiographic monitoring, or Holter method, has been shown to be an effective tool in veterinary medicine to detect early heart lesions, not only to monitor the electrical activity of the heart, but also to control the autonomic nervous system of this organ.

The ecology and management of feral pigs in the 'wet-dry' tropics of the Northern Territory

Caley, Peter, n/a January 1993 (has links)
This thesis is concerned with studying aspects of the ecology of feral pigs in the wet-dry tropics of the Northern Territory. The data are needed for use in the management of feral pigs to reduce their agricultural and potential epidemiological impact. Particular emphasis is placed on collecting data needed for modelling foot-and-mouth disease in feral pigs, estimating agricultural damage caused by pigs and evaluating control techniques. All fieldwork was conducted in the Douglas Daly district of the Northern Territory.

The primary principalship in the Northern Territory and Australian Capital Territory : a study of the changing role and procedures for promotion to the position

Hawkins, Clive Richard, n/a January 1991 (has links)
This study researched two major aspects of the primary school principalship in the Northern Territory and Australian Capital Territory viz., (1) How current trends in educational governance have affected the role of the principal, and (2) Assessment and selection procedures used for promotion to the principalship in the present educational environment. The context of the study has been outlined by presenting a brief historical and organisational overview of public education in both Territories, along with an examination of the literature on recent trends and issues in educational governance and promotion procedures. The research methodology used to examine the questions posed in this study is qualitative or descriptive in nature. The data was collected through the use of a semistructured interview technique and represents the ideas, opinions and perceptions of a specially targeted group of principals and aspiring principals from both education systems. The findings demonstrated that many aspects of the role of the primary principalship in the N.T. and A.C.T. are changing, due to a new set of values in educational policymaking and increased political control. There was a high degree of similarity between respondents in each Territory in regard to how the role is being reshaped. It was also found that the level of support provided by both systems to assist principals in coping with the changes has been inadequate and that the changes have led to a degree of conflict and new job-related pressures for most primary school principals. It was concluded that assessment and selection procedures should be rigorous and demanding, commensurate with the significance of the position. In this regard both educational systems need to improve present procedures by addressing perceived weaknesses. To this end assessment centres may have a role to play. Finally, further implications of the conclusions are addressed in terms of the necessity for thorough preparation and training of aspirants to the principalship to enhance their chance of selection and help them cope with the new expectations and demands of the position. This responsibility should be shared between the aspirant, professional associations and the employing education department.

Clinically Unrecognized Myocardial Scars Detected by MRI

Espregueira Themudo, Raquel January 2012 (has links)
A high percentage of unrecognized myocardial infarctions (UMIs) seen at delayed-enhanced magnetic resonance imaging (DE-MRI) are not detected by ECG. DE-MRI-detected UMIs are independent predictors of cardiovascular events in patients with coronary artery disease. In an elderly population, subjects with DE-MRI-detected UMIs do not have increased Framingham risk score or increased prevalence of artery stenosis in whole-body MR angiography as patients with recognized myocardial infarctions (RMI). Further investigation on the pathogenesis of DE-MRI-detected UMIs focus on the need to decide the management of these subjects. From the Prospective Investigation of the Vasculature in Uppsala Seniors, 248 subjects underwent cardiac MRI at age 70 and from these, 185 underwent a 5-year follow-up MR. DE-MRI-detected UMIs had lower signal intensity than RMIs probably reflecting different composition of their tissues. Subjects with UMI scar had increased levels of NT-proBNP, a predictor of increased risk of cardiovascular events. After 5 years, UMI scars were in their majority seen on the same location and with the same size, and their prevalence increased. Subjects with an UMI did not differ from subjects without a scar in terms of coronary stenosis assessed by computed tomography angiography or signs of ischemia on exercise test. In conclusion, DE-MRI-detected UMI scars are a frequent finding in an elderly population and its prevalence increases with age. The increased levels of NT-proBNP indicate that subjects with an UMI might have an increased rate of future cardiovascular events but the findings that these scars might have a different contrast distribution volume on MRI and that they are not related to CAD are indicators that they probably have a different etiology from RMIs. The prognosis of DE-MRI detected UMI scars in the general population is still unknown and therefore the clinical management of these individuals is yet to be defined.

New Risk Markers in Atrial Fibrillation

Hijazi, Ziad January 2013 (has links)
Atrial fibrillation (AF) confers an independent increased risk of stroke and death. The stroke risk is very heterogeneous and current risk stratification models based on clinical variables, such as the CHADS2 and CHA2DS2VASc score, only offer a modest discriminating value. The aims of this thesis were to study cardiac biomarkers, cardiac troponin and natriuretic peptides e.g. N-terminal prohormone-B-type natriuretic peptide (NT-proBNP), and describe levels in AF patients, investigate the association with stroke or systemic embolism, cardiovascular event, major bleeding and mortality, and to assess how levels of cardiac biomarkers change over time. Cardiac troponin was analyzed with contemporary assays and high sensitivity assays. The study populations consisted of patients with atrial fibrillation and one risk factor for stroke included in the RE-LY (n=6189) and the ARISTOTLE (n=14892) biomarker substudies. Median follow-up time was 2.2 years and 1.9 years, respectively. In a subset of participants (n=2514) data from repeated measurements was available at three months. Cardiac troponin was detectable in 57.0% with the contemporary assay and 99.4% with the high sensitivity assay. NT-proBNP was elevated in approximately three quarters of the participants. In Cox models adjusted for established risk factors the cardiac biomarkers levels was independently associated with stroke or systemic embolism, cardiovascular events, and mortality. Only cardiac troponin was associated with major bleeding. In ROC analyses the prediction of stroke or systemic embolism, cardiovascular events, and mortality increased significantly by addition of cardiac troponin or NT-proBNP to the models. Persistent detectable cardiac troponin (contemporary assay) and elevated NT-proBNP levels were found in a large number of participants. Persistent detectable or elevated levels conferred significantly higher risk for stroke or systemic embolism, cardiovascular events, and mortality. By using both cardiac biomarkers simultaneously the risk stratification improved even further for all outcomes. In conclusion the analyses for the first time display that elevation of troponin I and NT-proBNP are common in patients with AF and independently related to increased risks of stroke, cardiovascular events and mortality. Persistent elevation of troponin and NT-proBNP indicate a worse prognosis than transient elevations or no elevations of either marker. The cardiac biomarkers added substantial improvements to existing risk stratification models.
