Evaluation of various methods in clinical practice is often based on interpretations by two or more observers. Such data need to be analysed with correct statistics, or the results and conclusions may be misleading. In this study, the use of measures of agreement for ordinal data in five international nursing journals is reviewed and various methods for measuring agreement are presented and discussed. Analyses of agreement did not seem to be very common in nursing research, but a great variation was found regarding the choice of method for analysing agreement. Both acceptable and unacceptable methods were found in the articles reviewed. When choosing among various methods for agreement the weighted κ-coefficient is probably the most useful for ordinal data, but several issues of concern arise and need to be taken into consideration when using these types of analyses.. ...

The United States Air Force calibration program was initiated in January 1952 to comply with AF Regulation 74-2, which outlined policies and assigned responsibilities for managing the Air Force Metrology and Calibration (AFMETCAL) Program.[2] The Dayton Air Force Depot, located at Gentile Air Force Station, Dayton, Ohio, developed and implemented a plan to ensure traceability to national standards that would apply to all measurements made on any weapon system in the Air Force. The Dayton Air Force Depot was given the authority to establish a centralized calibration program. Under their plan, the Air Materiel Area Depots were given a set of measurement standards, which were periodically calibrated by the Dayton Air Force Depot using standards traceable to the National Bureau of Standards. The operational success of a "Test Shop" program set up at March AFB, California, on 15 September 1957, led to the establishment of the base-level Precision Measurement Equipment Laboratories providing the Air ...
The standard non-parametric test for paired ordinal data is the Wilcoxon, which is sort of an augmented sign test. I dont know of a formula for power analysis for the Wilcoxon, but you can certainly get power analyses for the sign test (there are various resources listed in my question here: Free or downloadable resources for sample size calculations). Note that (as @Glen_b notes in the comment below), this would assume that there are no ties. If you expect there will be some proportion of ties, the power analysis for the sign test would give you the requisite $N$ excluding the ties, so you would inflate that estimate by multiplying it by the reciprocal of the proportion of untied data you expect to have (e.g., if you thought you might have $20\%$ tied data, and the test required $N=100$, then youd multiply $100$ by $1/.8$ to get $125$). Unless you need the minimum $N$ to achieve a specified power, that should work for you. For example, when running power calculations for more complicated ...
A container housing liquid medication is provided together with a syringe and a coupling member for use in orally administering the medication to a patient. The coupling member is fastened to the container and includes a head member projecting upwardly to receive an inner tip of the syringe barrel. The liquid medication is dispensed from the container into a barrel of the syringe through a bore of the head member when a plunger is moved within the syringe barrel. After a predetermined amount of medication is received by the syringe barrel, the syringe barrel is removed from the head member and the predetermined amount of medication is administered orally to the patient. A cap member attached to the coupling member by means of a strap closes off the bore so that no medication escapes from the container when the syringe is disconnected from the head member. In one particular embodiment, a valve means is connected to the coupling member to permit selective communication between the container and the

The use of optical metrology techniques in process control for microelectronic manufacturing has become widespread. These techniques are fast and non-destructive, allowing a higher sampling rate than non-optical methods like scanning electron or atomic force microscopy. One drawback of most optical metrology tools is the requirement that special measurement structures be fabricated in the scribe line between chips. This poses significant limitations regarding the characterization of lithography processes that may be overcome via in-chip measurements. In this paper we present experimental results for an in-chip optical metrology technique that allows direct measurement of both critical dimensions and overlay displacement errors in the DRAM manufacturing process. This technique does not require special target structures and is performed on the actual semiconductor devices.. ©2009 Optical Society of America. Full Article , PDF Article ...

Downloadable (with restrictions)! Data mining is the process of extracting and analysing information from large databases. Graphical models are a suitable framework for probabilistic modelling. A Bayesian Belief Net (BBN) is a probabilistic graphical model, which represents joint distributions in an intuitive and efficient way. It encodes the probability density (or mass) function of a set of variables by specifying a number of conditional independence statements in the form of a directed acyclic graph. Specifying the structure of the model is one of the most important design choices in graphical modelling. Notwithstanding their potential, there are only a limited number of applications of graphical models on very complex and large databases. A method for mining ordinal multivariate data using non-parametric BBNs is presented. The main advantage of this method is that it can handle a large number of continuous variables, without making any assumptions about their marginal distributions, in a very fast

Host: Vladan Vuletic. Quantum metrology with Bose Einstein Condensates. One aspect of metrology, the science of measurement, is the exploration of the ultimate precision limit. It is known for quite some time that the new possibilities in quantum mechanics allow the surpassing of the ultimate classical precision limit given by counting statistics. Quantum metrology is about the exploration of these new limits. The goal is the generation and characterization of useful quantum mechanical resources for going beyond the classical precision limits. Since the gain in precision is intimately connected to quantum entanglement in many particle systems these investigations are also interesting from the fundamental point of view. In this colloquium I will discuss in detail how Bose Einstein condensates can be used to generate entangled many particle states which push atom interferometry beyond the classical limits. I will use the system of two component atomic condensates as a model system for explaining ...

An apparatus for infusing liquid medication such as insulin into a living body has a memory for storing a basic pattern and meal patterns which decide the medication infusion dose in accordance with time. The basic pattern is designated under ordinary conditions, with a meal pattern being designated for a predetermined period of time when desired. With the passage of the predetermined period, the basic pattern is restored, the address of the basic pattern being designated according to the actual time. When a pattern is selected, the one actually addressed and read out of the memory is that appropriate for the time of day. The pattern information read out of the memory is applied to means for infusing the liquid medication into the living body, the dose of the medication conforming to the specific pattern.

... is the study of short series of observations obtained from many respondents over time and is also referred to as panel analysis (of a cross-section of time series), or repeated measures, or growth curve analysis (polynomials in time), or multilevel analysis (where one level is a sequence of observations from respondents). Longitudinal analysis is used for panel surveys, experiments, and quasi-experiments in health and biomedicine, education and psychology, and the evaluation of prevention and treatment programs. This course treats the statistical basis and practical application of linear models for longitudinal normal data and generalized linear models for longitudinal binary, count, and ordinal data. The approach involves inclusion of random effects in linear models to reflect within-person cross-time correlation. Techniques for irregularly observed (unequally spaced) data will be covered. Examples and exercises will use both standard and special-purpose software. ...

Measure twice, cut once. Measurement proficiency is a skill learned and practiced by craftsmen for centuries. It is the first thing we all learned in shop class or in Dads garage workshop. A universal rule like this is never questioned because we all understand why it is important. Whether it means another trip to the hardware store or scrapping a high-value machined part, measurement errors are painful.. In todays world of computerized measurement systems, careful measurement is as important as ever. The benefits of using state-of-the-art systems are evident in how quickly a new user can start taking measurements. It wasnt too long ago when high-accuracy measurement was left to highly trained and experienced people wearing white coats in the metrology lab. Technology has ushered in easy-to-use, high-accuracy metrology on the shop floor, and put it into the hands of machinists, tool builders, and engineers.. These new measurement tools enable the highest quality processes while eliminating ...
