Paints and coatings have been recognized as a useful type of forensic evidence for several decades. During this time the materials themselves, the analytical methods used to examine them, and the legal environment surrounding the use of scientific evidence in courts have all changed. This paper is not intended to provide a comprehensive bibliography on the topic, but rather to provide a concise...

The digital resources construction of college library is important for the development of college, therefore it is necessary to evaluate it base on an effective evaluation method, and the application of fuzzy analytic hierarchy process on it is studied in depth. Firstly, the meaning of performance evaluation of digital construction of college library is discussed; Secondly, the digital resource...

With growingworldwide awareness of environmental protection, green production has become an important issue for almost every manufacturer and will determine the sustainability of a manufacturer in the long term. A performance evaluation system for green suppliers thus is necessary to determine the suitability of suppliers to cooperate with the firm. While the works on the evaluation and/or sele...

In this paper different methods supporting a new intensity formula in optical emission spectroscopy are presented. Three independent experimental and analytical methods have been developed which strongly support this new formula. Different light sources have also been used in this work. A new theory has earlier also been presented which strongly verify the new formula. Support is also given fro...

Subconductor methods or partial wire methods yield reliable results for conductor parameters such as inductance, capacitance, conductance and resistance and can be used to estimate these parameters for conductor configurations involving complex geometries which cannot be handled using analytical methods. The values of inductances obtained using partial wire method are critically compared with v...

Making use of mechanical resonance has many benefits for the design of microscale devices. A key to successfully incorporating this phenomenon in the design of a device is to understand how the resonant frequencies of interest are affected by changes to the geometric parameters of the design. For simple geometric shapes, this is quite easy, but for complex nonlinear designs, it becomes signific...

Previous injury is believed to be a causal risk factor for subsequent injury. Using empirical data on circus artists (n = 1,281 artists) between 2004 and 2008 in Montreal, Canada, as a motivating example, the authors use patient vector plots to demonstrate that a bias away from the null must always occur in the typical analyses cited as evidence (i.e., survival analysis, Poisson regression), ex...

This is a compilation of reference materials suggested for scientists considering a laboratory reference collection in clinical chemistry, or for librarians seeking to develop or add to an up-t-o-date library collection. Nine areas are represented: general clinical chemistry; analytical methods, procedures, and techniques; calculations and statistics; the clinical laboratory; drugs and metaboli...

A finite memory is introduced in the score dynamics of Minority Games. As expected, this removes the dependence of the stationary state on the initial conditions. However, it also causes an unexpected increase of fluctuations in grand-canonical models for very large times. Current analytical methods are inadequate to solve this simple and natural extension.

Large, longitudinal, multivariate population surveys are increasingly common. Many analytic methods inspect changing rates of individual outcomes but ignore heterogeneous subpopulations that may exist. In this document I propose two analytical methods which extend group-based trajectory models to multivariate outcomes. I use group-based longitudinal finite mixture models (i.e., developmental tr...
