Abstract Although RIL, SDL and LADA are slightly different, the main operating principle is the same and the theory for defect localization presented in this paper is applicable to all three methods. Throughout this paper the authors refer to LADA, as all experimental results in this paper were obtained with a 1064nm laser on defect free circuits. This paper first defines mathematically what 'signal strength' actually means in LADA and then demonstrates a statistical model of the LADA situation that explains the optimal conditions for signal collection and the parameters involved. The model is tested against experimental data and is also used to optimise the acquisition time. Through this model, equations were derived for the acquisition time needed to discern a LADA response from the background noise. The model offers a quantitative tool to estimate the feasibility of a given LADA measurement and a guide to optimising the required experimental set-up.

AbstractThis paper deals with the theoretical analysis of the spatial concentration and localization of firms and employees over a set of regions. In particular, it provides a simple site-selection theoretical model to describe the probabilistic framework of the location patterns. The adopted quantitative tool is the stochastic theory of urns. The model moves from the empirical evidence of the deviation of the spatial location of companies from the uniform distribution and of employees from the distribution of firms. Factors leading to such deviations are taken into consideration. Specifically, we formalize a decision problem grounded on the economic attributes of the regions and also on the distribution of the existing firms and employees in the territory. To our purpose, the site-selection model is presented as a stepwise process.

The competitive exchange rate devaluation (or currency protectionism) is a phenomenon of global political economy, which goes hand in hand with trade activities. The causes, consequences and effects of monetary protectionism for the concerned countries have been thoroughly analyzed on the basis of existing literature. An important element of analysis is the different effects of the implementation of protectionist policy measures on trading partners. An example of currency protectionism nowadays is the currency competition between the US and China. Although the US is the "hegemon" of the modern international economic-political system, China's continuous, upward and rapid economic course has weakened the primacy of the US, with consequences that are perceived in the global economic system. Of course, China has been accused of practices of economic "mercantilism." On the basis of these mercantilist accusations, a kind of war broke out with the US. But the main question is this: how are the exports of trading partners affected by this currency competition? To be able to answer this question more fully, a quantitative tool should be created that can interpret the effects of currency competition on trading partners. This study will try answering this question by using the case study of U.S. - China currency competition. The methodology applied is the creation of a Composite Index.

The Montreal Battery for the Evaluation of Amusia (MBEA; Peretz, Champod, & Hyde, 2003) is an empirically-grounded quantitative tool that is widely used to identify individuals with congenital amusia. The use of such a standardized measure ensures that individuals tested conform to a specific neuropsychological profile, allowing for comparisons across studies and research groups. Recently, a number of researchers have published credible critiques of the usefulness of the MBEA as a diagnostic tool for amusia. Here we argue that the MBEA and its online counterpart, the AMUSIA tests (Peretz et al., 2008), should be considered steps in a screening process for amusia, rather than standalone diagnostic tools. The goal of this article is to present, in detailed and easily replicable format, the full protocol with which congenital amusics should be identified. In providing information that often goes unreported in published articles, we aim to clarify the strengths and limitations of the MBEA, and make recommendations for its continued use by the research community as part of the Montreal Protocol for Identification of Amusia (MPIA).
