the effect of inter-implant distance on retention and resistance of implant-tissue-supported overdentures is lacking in the literature. an in vitro study was performed to evaluate this effect for mandibular implant-tissue-supported overdentures retained by two ball attachments.an acrylic cast of an edentulous mandible was fabricated. three pairs of implants were symmetrically placed at both sid...

this study aims to develop seismic fragility curves for a typical pile-supported wharf. fragility curve is one of the popular tools in seismic performance evaluation of a structure. the software flac2d was used to simulate the seismic performance of the wharf structure. using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (ida) was applied for sei...

a condensation of various isatins with indole derivatives has been carried out in the presence of 1,3-dibromo-5,5-dimethylhydantoin (dbdmh) as catalyst at 50 °c in ethanol in order to form 3,3-bis(indolyl) oxindoles. the products were obtained within 20-90 min by 70-96% yields. the efficacy of the procedure has been confirmed by catalyzing the condensation reaction of pyrrole which was used as ...

The World Wide Web is becoming a dominating factor in Information Technology. Consequently, Computer-Supported Cooperative Work on the Web has recently drawn a lot of attention. “Process Support for Cooperative Work” (PSCW) is a Web-based system supporting both structured and unstructured forms of cooperation. It is a combination of the “Basic Support for Cooperative Work” (BSCW) shared workspa...

The Airbus Visual Line (AVL) project, now deployed on the A380 assembly line, was propelled by the desire to foster collaboration and coordination among aeronautical Final Assembly Line teams while going beyond the simplistic – repressive concept of “andon boards” (Monden, 1993). We introduced an environment composed of large public displays and semi-public interfaces to support this collaborat...

Computer-Supported Cooperative Work (CSCW) in Design explores the potential of computer technologies to help cooperative design. It requires more efficient technologies of communications and reusing knowledge in design process. This paper looks at CSCW in Design on the Semantic Web and shows how the Semantic Web technologies may improve the current design process. It describes using the Semanti...

The areas of computer-supported cooperative work (CSCW) and computer-supported cooperative learning (CSCL) have co-existed next to each other for a long time. The co-existence has been a peaceful one, but then again, the relationship between the two fields has been characterized by little interaction. It might therefore be timely to consider if this state of affairs is as it should be. Some res...

In this chapter, we examine how mass communication can be extended with collaborative interactivity on a shared screen that facilitates and promotes cooperation between two opposing groups of people. In particular, a shared screen that displays a map narrative becomes a representation of a shared physical space, which is claimed by two conflicting groups. In our work, a double screen projection...

(eds.), ECSCW 2015: Proceedings of the 14th European Conference on Computer Supported Cooperative Work, 19–23 September 2015, Oslo, Norway, DOI 10.1007/978-3-319-20499-4_2 Abstract We have investigated techniques for mining programming activity to offer help to programmers in difficulty. We have developed a (a) difficul...

CSCW (Computer Supported Cooperative Work) is an idea that was demonstrated as early as in the 1960s by Engelbart’s pioneering work on the On-Line System (NLS) [Eng75a], which offered computer-supported conferencing. Since that time, a variety of CSCW applications have been developed at several research laboratories and universities. Education is an inherently cooperative activity involving at ...
