Abstract:
Weld defect inspection is an essential aspect of testing in industries field. From a human viewpoint, a manual inspection can make appropriate justification more difficult and lead to incorrect identification during weld defect detection. Weld defect inspection uses X-radiography testing, which is now mostly outdated. Recently, numerous researchers have utilized X-radiography digital images to inspect the defect. As a result, for error-free inspection, an autonomous weld detection and classification system are required. One of the most difficult issues in the field of image processing, particu

Organizations are under constant threat from global competition, socioeconomic factors, and political forces that are often unforeseen and dynamic. Consequently, decision makers adopt strategies, some including the principles of modularity, as a countermeasure.

Abstract:
In recent years commentators have suggested that the law of contract is experiencing something of a legitimation crisis. Whilst the classical contract paradigm remains a compelling default model underpinning contract law it is seen as increasingly remote from commercial practice. Legal scholars have variously described contract theory and doctrine as incoherent, piecemeal or in a state of flux. In spite of these issues having been well aired by academics, and the judiciary, no compelling alternative model seems to have emerged.

Appliqués aux déséquilibres entre professionnels, les outils mis en œuvre pour assurer ce contrôle trahissent l’existence d’un contrôle objectif de l’équilibre attendu du contrat.

Abstract:
The moral significance of negligence is regularly downplayed in the legal and philosophical literature. Two common tenets about negligence diminish its perceived importance: first, culpable negligence is substantially less significant than malice (as well as other intentionally inflicted wrongs); second, considered apart from its consequences, culpable negligence is a rather petty moral wrong. This paper argues, by contrast, that culpable negligence can be a serious moral and political wrong and non-negligence is a significant moral virtue.

Abstract:
A future helicopter vehicle management system must include technologies to minimize the impact of externally slung loads on the helicopter's controllability. Two proposed technologies, active cargo hooks (ACH) and stabilization through the flight control system, termed the Flight Control Load Stabilization (FCLS), are developed. A hybrid combination of the two technologies is also explored. The design and simulation of the technologies culminates in the flight testing of the ACH and FCLS, with the hybrid mode being flown for the first time. The results showed the ACH system significantly impro

Abstract:
In this paper, we investigated the thermal conductivity of three-dimensional nanocomposites composed of randomly distributed nanoparticles with large thermal conductivity differences in the constituents. Nanoparticles in composite materials fabricated by processes such as hot press or spark plasma sintering tend to be randomly distributed. For composites made of particles with high thermal conductivity contrast ratio, percolation theory predicts the existence of a continuous phase of high thermal conductivity material when its volumetric concentration reaches beyond the percolation threshold.

Abstract:
We examined the effects of luminance contrast and spatial frequency on chromaticity discrimination of grating bars. The apparatus was a computer-controlled Maxwellian view stimulator with a 2-mm artificial pupil. The 2° square-wave gratings ranged from 1.07 to 8.6 cpd. Alternate bars were filled with light of a standard wavelength and light that could be varied in wavelength with a monochromator. The variable bars were set 0.2, 0.1, 0.03, or 0.0 log unit brighter or dimmer than the standard. The observers’ task was to match the variable bars to the standard bars in hue.

Abstract:
Visual acuity measurement is a critical tool in the clinical assessment of visual function and in the identification of changes affecting the visual system. Traditionally, visual acuity is measured with letter charts with black letters presented in high contrast against a white background. While authoritative bodiesl.2 have made various recommendations about test chart design and calibration of optotypes, there is not a universally accepted standard. It has become common in clinical research to use charts which follow the design principles of Bailey and Lovie3 which ensure that the task is ess

Abstract:
We study a model of the impact of climate risk on credit supply and test its predictions using data on all wildfires and corporate loans in Spain. Our findings reveal a significant decrease in credit following climate-driven events. This result is driven by outsider banks (large and diversified), which reduce lending significantly to firms in affected areas. By contrast, due to their access to soft information, local banks (geographically concentrated) reduce their loans to opaque affected firms to a lesser extent without increasing their risk. We also find that employment decreases in affecte

Abstract:
Using unique data from Pakistan, we estimate a model of demand for differentiated products in 112 rural education markets with significant choice among public and private schools. Families are willing to pay substantially for reductions in distance to school, but in contrast, price elasticities are low. Using the demand estimates, we show that the existence of a low fee private school market is of great value for households in our sample, reaching 2 percent to 7 percent of annual per capita expenditure for those choosing private schools.

Abstract:
This paper examines the economic effects of employment protection legislation in a sample of developed and developing countries. Implementing a difference-in-differences test lessens the potentially severe endogeneity and omitted variable problems associated with cross-country regressions. This test is based on the hypothesis that employment protection regulations are more binding in sectors of activity exposed to higher volatility in demand or supply shocks. The analysis indicates that more stringent legislation slows down job turnover by a significant amount, and that this effect is more pro

Abstract:
This paper studies the effect of fiscal rules on debt affordability in a large set of developed and emerging market economies, using a panel data model which allows the inclusion of weakly exogenous regressors, and which deals appropriately with cross-sectional dependence. The results show a positive and significant effect of fiscal rule implementation on public debt affordability which is robust to various model specifications. The effect is stronger for emerging market economies which benefit from the implementation of any fiscal rule. In contrast, developed countries benefit only from high-

Abstract:
We explored the hypothesis that the Programme of Advancement through Health and Education (PATH), Jamaica's conditional cash transfer program, contributes to breaking the inter-generational poverty cycle by placing its urban beneficiaries on a higher educational trajectory. Using a regression discontinuity design, we found that PATH urban male beneficiaries who sat the Grade Six Achievement Test (GSAT) over the period 2010-2014 performed better on the test (scoring 16.03 points, or 3.6%, higher than non-beneficiaries); consequently, they were placed in better secondary schools (1.5 percentiles

The data presented in this report show that mothers with children under 7 years of age participate less in the labor market than those with no children, except for single mothers. Another interesting result is that female labor force participation generally increases with age and d

Abstract:
Odonates are significant components of most wetland habitats and important indicators of their health. At Cape Cod National Seashore (CACO), we compiled odonate records dating back to the 1980s and, based partly on that data, identified 41 wetland sites for sampling, representing six freshwater habitats (kettle pond, inter-dune pond, dune slack, riparian marsh, vernal pool, and bog). We surveyed these sites for adult odonates during the 2016?2018 field seasons. Ten sites were surveyed all three years (total 19-20 surveys/site); all ten had at least some historical data.
