2.1 Fiber Endface Conditions Required for PC Connection Figure 1 shows the structure of an 8-fiber MPO connector. To decrease reflection, fiber endfaces in this kind of connector are polished at a gradient of 8° to the fiber cross section. The connector endfaces are held together by the engagement of the guide pins in guide-pin holes. To achieve PC connection in such a connector, it is necessar...

Low-power vacuum pumps are commonly used for Southern and Northern transfer from agarose gels and for slot and dot blotting. Unfortunately, commercially available vacuum pumps are expensive and susceptible to contamination with transfer reagents. The following describes the use and construction of a very simple and cheap apparatus, which generates and measures a partial vacuum as effectively as...

This paper presents an approach to ®nd feasible and practical plans for mechanical assemblies based on a connector-based structure (CBS) hierarchy. The basic idea of the approach is to construct plans for an assembly (i.e. the root node of the CBS hierarchy) by systematically merging plans for primitive structures in the CBS hierarchy, while the plans for primitive structures are built using on...

objective: in all ceramic fixed partial dentures the connector area is a common fracture location. the survival time of three-unit fixed partial dentures may be improved by altering the connector design in regions of maximum tension. the purpose of this study was to determine the effect of buccolingual increase of the connector width on the stress distribution in posterior fixed partial denture...

The Reo coordination language is an extensible graphical notation for component or service coordination wherein independent autonomous software entities exchange data through a connector or a network imposing synchronization and data constraints on those entities. Each connector is formed from a set of binary connectors, called channels, with precise semantics and, thus, amenable to formal veri...

We suggest a formal model to represent and solve the multicast routing problem in multicast networks. To attain this, we model the network adapting it to a weighted and-or graph, where the weight on a connector corresponds to the cost of sending a packet on the network link modelled by that connector. Then, we use the Soft Constraint Logic Programming (SCLP) framework as a convenient declarativ...

Assembly planning attempts to arrange product assembly sequences on the basis of the input of product description, similar assembly plans and assembly constraints. Assembly planning is frequently viewed as a creative thinking process, which requires extensive assembly planning experience. Assembly product modeling with mechanical connection functions has increasingly focused on assembly sequenc...

Most diagram editors and graph construction tools provide some form of automatic connector routing, typically providing orthogonal or poly-line connectors. Usually the editor provides an initial automatic route when the connector is created and then modifies this when the connector end-points are moved. None that we know of ensure that the route is of minimal length while avoiding other objects...

An optical package for mounting VCSEL and PIN diodes for transmitting and receiving optical signals has been developed. The diodes couple to the fibers in a commercial MT connector. The package is quite compact with its physical size significantly smaller than that of the MT connector. This design simplifies the testing and assembly of the optical components because the MT connector with the lo...
