The retrieval of column densities and concentration profiles of atmospheric trace gas species from satellites is sensitive to light scattered by clouds. The SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument on the Envisat satellite, principally designed to retrieve trace gases in the atmosphere, is also capable of detecting clouds. FRESCO (Fast Retriev...

İş ortamının ergonomik açıdan yetersiz olmasının sonucu olarak, çalışanların kas iskelet sistemi rahatsızlıklarına yakalanma olasılığı artmaktadır. Kas rahatsızlıkları meslek hastalıklarının önemli bir bölümünü oluşturur. defa ortaya çıktıktan sonra tedavisi oldukça zaman alıcı ve masraflıdır; ayrıca çalışanın devamsızlığına yol açar. Dolayısıyla, işletmelerin insan kaynağını verimli şekilde ku...

The objectives of this study were to examine the agreement between 5 ergonomic risk assessment methods calculated on the basis of quantitative exposure measures and to examine the ability of the methods to correctly classify 4 at risk jobs. Surface electromyography and electrogoniometry were used to record the physical exposures of 87 sawmill workers performing 4 repetitive jobs. Five ergonomic...

Contract-based design is an emerging paradigm for correctby-construction hierarchical systems: components are associated with assumptions and guarantees expressed as formal properties; the architecture is analyzed by verifying that each contract of composite components is correctly refined by the contracts of its subcomponents. The approach is very efficient, because the overall correctness pro...

The definitions of methods and tools used to evaluate how workers perceive the comfort during their activities remains an “open” problem at this time. Many researchers have dealt with that problem in the last twenty years, focusing their efforts primarily on the automotive sector and on VDT workstation comfort. This paper analyzes how workers position themselves at workstations used in industri...

This paper presents a model-based approach for competitive analysis of manufacturing plants in the U. S. food processing industry. As part of this approach, plant competitiveness is measured using Operational Competitiveness Ratings Analysis (OCRA) -a new non-parametric method of computing relative inefficiency. Drivers of competitiveness are identified in terms of policies related to plant str...
