Connection principle

The principle of the greatest number of connections (connection principle). To understand the meaning of this principle it may first be necessary to define the concept of connection. To this end we consider a certain crystal structure and imagine connecting each atom with the other atoms present in the structure by straight lines. There will be a shortest segment between any two atoms. We will... 

The useful screw-thread connector is becoming widely available. The simplest is the screw-capped adapter (Fig. 2.32) where the screw-capped joint is associated with a ground glass cone. The figure shows the silicone rubber ring and PTFE washer, and the adapter is useful for the insertion of gas tubes, thermometers or stirrer shafts. The screw-thread connection principle has been applied to the connection of water hoses to condensers and vacuum lines to Buchner flasks, to securing simple sealing septa to flasks, etc. 

CPC developed a series of table-top micro reaction systems called CYTOS (Figure 4.22), SEQUOS and OPTIMOS based on a standardized platform. CYTOS is the basic laboratory system with internal and external modularity for high flexibility by running different chemical reactions. The internal modularity offers the realization of variable reaction times up to 45 min by using several residence time units. The external modularity provides a system configuration for a multi-step synthesis. CPC Systems individual connecting principle minimizes the dead volume in the system and provides the reaction with isothermal conditions through the whole system [74, 75]. 

The connection principle leads to the occurrence of atom groups with the shortest interatomic contacts referred to as connections according to Laves Owing to the ability of chemical bonds to be coordinated in certain directions, these connections may be finite formations which are called groups and islands, respectively (see Sect. 3). Onedimensional, two-dimensional and three-dimensional infinite connections are called chains, layers and skeletons, respectively. 

The international journal Composite Structures provides a wealth on papers on composite bolted joints. Other journals such as Composites Science and Technology, Composites, Part A B and the Journal of Composite Materials all have excellent papers on composite bolted joints in their archives. The recently published book Composite Joints and Connections Principles, Modelling and Testing [59] is a dedicated text on composite joints and connections and is highly recommended as an introduction to the subject.

Depending on the railway line GSM-R ensures voice and/or data transmission using cellular digital mobile system. BTS base stations along the railway lines as well as architecture of the coimectivity are function dependent— transmission safety, reliability, availability— voice, data transmission. As a result locations of the BTS base stations as well as connectivity principle have to be determined line by line taking into account class and purpose of the line, required capacity and required safety measures (Pawlik 2007).
