We investigate the influence of launching conditions on misalignment tolerance of pluggable ballpoint-pen interconnects, where graded-index plastic optical fibers (GI POFs) are coupled with ball lenses mounted on their end faces. The lateral-misalignment tolerance of the ballpoint-pen connector decreased with an increase in the driving current of a vertical cavity surface emitting laser (VCSEL)...

This paper describes the Connector and Acceptor patterns. The intent of these patterns is to decouple the active and passive initialization roles, respectively, from the tasks a communication service performs once initialization is complete. Common examples of communication services that utilize these patterns include WWW browsers, WWW servers, object request brokers, and “superservers” (which ...

OBJECTIVES The level of environmental contamination generated during preparation and administration of hazardous drugs using different valve closed-systems and their combinations was compared. The actual impact on the overall time of preparation of cytostatics and the economic cost of the different modalities were also compared. METHODS Comparative study of the preparation of fluorescein mixt...

Community structure detection has proven to be important in revealing the underlying properties of complex networks. The standard problem, where a partition of disjoint communities is sought, has been continually adapted to offer more realistic models of interactions in these systems. Here, a two-step procedure is outlined for exploring the concept of overlapping communities. First, a hard part...

Connectors are used in component-based systems as first-class entities to abstract component interactions. To explain their responsibilities, several taxonomies have been published to date. However, most of them mix different levels of abstraction and fail to provide any guidelines that address different component interconnections through “real connectors” (employed in assembling real-life appl...

Joint connection methods, such as shear key and loop bar, improve the structural performance of precast concrete structures; consequently, there is usually decreased workability or constructional efficiency. This paper proposes a high-efficiency skewed pipe shear connector. To resist shear and pull-out forces, the proposed connectors are placed diagonally between precast concrete segments and a...

Reo is an exogenous coordination language based on a calculus of channel composition. Different formal models have been developed for this language. In this paper, we present a new approach to modeling and analysis of Reo connectors using Alloy which is a lightweight modeling language based on first-order relational logic. We provide a reusable library of Reo channels in Alloy that can be used ...

this study set out to investigate the distribution of the syntactic properties associatedwith the prodrop parameter by persian-speaking l2 learners of english in an attemptto examine the (un)attainability of native-like knowledge and (in)accessibility of ugin adult sla. to do so, 92 participants were assigned into different levels of l2knowledge based on their performances on the oxford placeme...

BACKGROUND Automated distal connecting devices have been recently introduced to facilitate coronary anastomosis. This could have a large impact on the capacity of robotic systems to perform completely endoscopic off-pump bypass, where the quality of anastomosis and the prolonged operative time for the performance of the anastomosis have until now been cause for concern. Our group tried to deter...
