A proposed mapping method for aligning machine execution data to numerical control code

2019

The visions of the digital thread and smart manufacturing have boosted the potential of relating downstream data to upstream decisions in design. However, to date, the tools and methods to robustly map across the related data representations is significantly lacking. In response, we propose a mapping technique for standard manufacturing data representations. Specifically, we focus on relating controller data from machining tools in the form of MTConnect, an emerging standard that defines the vocabulary and semantics as well as communications protocols for execution data, and G-Code, the most widely used standard for numerical control (NC) instructions. We evaluate the efficacy of our mappin…

Towards a virtual factory prototype

2015

International audience; A virtual factory should represent most of the features and operations of the corresponding real factory. Some of the key features of the virtual factory include the ability to assess performance at multiple resolutions and generate analytics data similar to what is possible in a real factory. One should be able to look at the overall factory performance and be able to drill down to a machine and analyze its performance. It will require a large amount of effort and expertise to build such a virtual factory. This paper describes an effort to build a multiple resolution model of a manufacturing cell. The model provides the ability to study the performance at the cell l…

Physico-chemical study of the radiopharmaceuticals 99mTc-DMSA, 99mTc-EDTA and 99mTc-DTPA interaction with plasmatic proteins.

1989

This report studies the binding rate of the radiopharmaceuticals 99mTc-DTPA, 99mTc-EDTA and 99mTc-DMSA to plasmatic proteins. The proteins bind to the tested radiopharmaceuticals in the following sequence: 99mTc-DTPA less than 99mTc-DMSA(C1) less than 99mTc-EDTA less than 99mTc-DMSA(C2) where C1 and C2 represent two different Tc-DMSA complexes. The thermodynamic study suggests a quantitative relationship of radiopharmaceutical:protein = 1:1 and an almost nonexistent influence of the temperature, which means that the interacting forces in this process are relatively weak.

RCBF-quantification with 99mTc-HMPAO-SPECT: theory and first results.

1989

The activity concentrations of 99mTc-HMPAO in brain after intravenous injection were evaluated in 25 patients using SPECT. With additional first pass studies of heart and brain with the short lived isotope 195mAu, the cardiac output and the mean cerebral transit times of the patients were measured a short time before the HMPAO injection. The time dependence of 99mTc-HMPAO activity in the brain was registered during the first 5 min after injection over both hemispheres. Using a simplified three compartment model it was possible to calculate the mean retention fraction of HMPAO in brain from the time activity curves. It could be shown that the regional cerebral blood flow in ml/min per 100 g …

Quantitative Cerebral Blood Flow Mapping in Stroke and During Mental Stimulation After Intravenous Injection of 195mAu

1985

The new short life isotope 195mAu has some suitable features for quantitative cerebral blood flow mapping. Its half-life is 30.5 s; therefore an injection can be repeated after 3 min (six half-lives) without any need for background subtraction and with the same specific activity. The calculated whole body radiation dose after three successive administrations of 25 mCi 195mAu amounts to 50 mrad. In comparison to a 99mTc pertechnetate injection it is estimated that the dose to the patients is reduced by a factor of eight (Garcia et al. 1981).

Vairogdziedzera mezglu analizēšana, izmantojot attēlu diagnostikas klasifikācijas un datu sistēmu (TIRADS), un salīdzinot ar Bethesda sistēmu

2017

Vairogdziedzera attēlu diagnostikas klasifikācijas un datu sistēma (Thyroid Imaging Reporting and Data System, TIRADS) ir klasifikācijas sistēma, kas iedala mezglu malignitātes riskus. Katra kategorija reprezentē vairogdziedzera mezgla malignitātes risku. Tā izveidota ar mērķi uzlabot reaģēšanu un izmaksu pārvaldību, samazinot vajadzību pēc ar tievu adatu aspirācijas biopsijas pacientiem, kuriem ir vairogdziedzera mezgli. TIRADS sistēma ir riska novērtēšanas sistēma vairogdziedzera audu bojājumu klasificēšanai. TIRADS novērtējums sniedz informāciju par vairogdziedzera struktūru, malignitātes risku un klasifikāciju. Bethesda sistēma vairogdziedzera citopatoloģiju novērtēšanai ir vairogdziedz…
