Even Toned Screening has evolved from a research project into a practical module for halftoning on color inkjet printers, with many commercial and free software users worldwide. Feedback from these users has motivated tuning and other modifications to make the algorithm more practical. This paper discusses both the core algorithms and the practical issues involved in driving real printers for r...

We explore the artificial life domain which opens new horizons to find bio-inspired solutions to image processing problems. Besides the ants which were successfully used, we investigate a new approach based on the interaction of social spiders, where we adapt the collective web weaving to an image segmentation on regions. Spiders were successfully used to extract regions on grey level images. W...

Background: In the textile industry, male migrant workers from other Indian states predominate. Workers are more vulnerable to occupational hazards due poor working conditions, such as long hours and workplace annoyances. These include noise, high temperatures, humidity, chemical fumes, cotton or synthetic dust, which harm their health. This study investigated morbidity patterns of in Surat. Me...

purpose : to determine the effect of carpet weaving on refractive errors methods : in this cross sectional study, carpet weavers and non-weavers in the normal population of mashhad were regarded as exposed and non-exposed groups, respectively. a carpet weaver was a person who wove carpets 7 hours a day for at least 2 years. the non-weavers group was selected from the population of mashhad throu...

Mulhern Automated proof assistants provide few facilities for incremental development. Generally, if the underlying structures on which a proof is based are modified, the developer must redo much of the proof. Yet incremental development is really the most natural approach for proofs of programming language properties [5, 12]. We propose " proof weaving " , a technique that allows a proof devel...

To reuse one or several existing systems in order to develop a complex system is a common practice in software engineering. This approach can be justified by the fact that it is often difficult for a single Information System (IS) to accomplish all the requested tasks. So, one solution is to combine many different ISs and make them collaborate in order to realize these tasks. We proposed an app...
