Taming complexity is a fundamental goal of software engineering. The core techniques that have been successful in practice are those that separate concerns, especially variants of architectural abstractions called components and connectors. We argue that General Theories of Software Engineering (GTSE) should be organized by components and connectors to distinguish conceptually distinct elements...

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

The grouted sleeve lapping connector called the APC has advantages of high fault tolerance, convenient construction, compacted grouting, and low cost, together with realizing full prefabrication vertical components. In this paper, a quasi-static test two fully prefabricated L-shaped walls connected types cast-in-place wall was carried out under axial compression ratio (0.5) to compare their sei...

During the operation of BEPC, the cable isolation layer near the high voltage connector of the DC separator is often melted, which is probably caused by the HOMs power. This paper presents the measurement results of the HOMs shunt impedance, the calculation of the power dissipated in the separator and through the connector, and the analysis of the HOMs effects.

We have developed a 7-core-fiber connector. To maintain both the ferrule floating mechanism and precise alignment around the ferrule axis, we employed Oldham's coupling mechanism inside the MUtype connector plug housing and realized an average attenuation of 0.13 dB and an average return loss of 46.8 dB.

Two-dimensional self-assembly of DNA origami structures was carried out using a connector that has connection sites at all four edges. By utilizing this four-way connector, five and eight origami monomers were assembled to form a cruciate and a hollow square structure, respectively.

The purpose of the present study was to determine the relationship between cross-sectional design and fracture load using a static load bearing test in yttria-stabilized tetragonal zirconia polycrystal ceramic frameworks on a molar fixed partial denture. The test framework was designed as a 3-unit bridge with two abutment teeth at the second premolar and second molar of the mandible. The cross-...

This article is part of a continuingseries that describes objectoriented techniques for developing reusable, extensible, and efficient communication software. The topic of this article is the Connector pattern. This design pattern enables the tasks performed by network services to evolve independently of the mechanisms that actively initialize the services. The Connector pattern is a companion ...
