Object-oriented programming elements

All object-oriented programming languages provide a feature called access modifier that facilitates separations between the interfaces and the implementations of an object. The way to achieve this result is to define member variables of the object as private or protected and define methods that provide services to the object s client as public. Only the public elements of an object can be accessed by its clients, and these are all that its clients care to know. In Java and C, we can go even further by creating interfaces that have only method signatures. The implementations of these methods are provided by the classes that implement these interfaces. Although there is no interface in C + +, you can, however, create an abstract class by declaring one or more of the class s methods as pure virtual. Abstract class is also supported by Java and C. Interfaces and abstract classes are useful software constructs for defining abstractions in a software system. 

LCR uses a graph theoretic representation of molecular structures, wherein nodes are atoms and edges are bonds. Three modeling elements are employed to create and describe chemical structures. Each modeling element has been implemented as a class, in an object-oriented programming environment, and is described by a set of attributes and a set of procedures. 

Abstract This contribution deals with the modeling of coupled thermal (T), hydraulic (H) and mechanical (M) processes in subsurface structures or barrier systems. We assume a system of three phases a deformable fractured porous medium fully or partially saturated with liquid and a gas which remains at atmospheric pressure. Consideration of the thermal flow problem leads to an extensively coupled problem consisting of an elliptic and parabolic-hyperbolic set of partial differential equations. The resulting initial boundary value problems are outlined. Their finite element representation and the required solving algorithms and control options for the coupled processes are implemented using object-oriented programming in the finite element code RockFlow/RockMech. 

A prototype system framework of PEEE has been developed using Java and Visual Basic as object-oriented programming languages, while SQE server and MS-Access are used as RDBMS for data repository for the plant model elements. Such prototype solution will enable all plant users to utilize a standard user interface to manipulate plant lifecycle data/information/knowledge. The prototype system can be used as the framework to develop CAPE-SAFE as well as other components within PEEE. 

RockFlow is a simulator that is used to model near-field situation of the type described above (Kolditz et al. (2003)). It is a finite element code, programmed using object-oriented techniques. Object-orientation allows a wide spectrum of applications for the code, and also simultaneous code development (Kolditz (2002)). This paper... 

Fig. 4.3 The DMC meta-modeling architecture with platforms for computation (instruction set), object-orientation, and service-orientation. Each platform is shown as the instance of DMC triplet with corresponding executable item (exec code, object, service provider). The top layer of the architecture shows elements of service-oriented modeling. That complements exertion-oriented programming. The service platform manages the service providers (virtualization of service cloud —V3/V4 that are autonomically provisioned by the SOS on virtualized computation/object platforms (yHV2)...

EChem++ [9, 14] is based on adaptive finite elements. Both reaction mechanisms and experimental conditions (such as the potential or current program applied to the electrode as an excitation of the electron transfer processes) can flexibly be formulated. It is an open-source program maintaining principles of object-oriented software design [21] and is under continuous development. 

Efficacy-oriented trials are usually conducted after initial safety-oriented trials have established that the intervention has met safety criteria, but they will always have safety questions and elements as well. In this type of study, the goal is to objectively determine the therapeutic effect. Whatever the type of intervention, these studies are designed around the bottom-Hne question Is the intervention effective In many cases (e.g., drugs for neurologic disorders, exercise programs for musculoskeletal injuries, etc.).
