“…The results of the current study were compared to the results of a previous study to validate the validity and correctness of the present analysis. Table 3 and 4 shows the comparison values with previous published results reported by Das et al, [42], Ulgen et al, [43] and Ishak et al, [38]. It is seen that the present values 𝜌𝜌 𝑛𝑛 𝑅𝑅𝑅𝑅 𝑥𝑥 1 2 , are in very good agreement in Table 3…”

The study through a stretching medium is a topic in the field of fluid dynamics and heat transfer. It involves investigating the behaviour of fluid flow and heat transfer phenomena in situations where a medium, such as a solid surface, is continuously stretched or deformed. Jeffrey fluid are found in the applications in various fields, including engineering, materials science, and biomedical engineering. Water was combined with copper (Cu) and aluminium oxide (Al2O3) is used in this study by considering the influence of nanoparticles shape which are spherical, brick, cylindrical, platelet and blade. The Keller Box method is used to solve numerically the Jeffrey hybrid nanofluid's governing nonlinear partial differential equations (PDEs) to nonlinear ordinary differential equations (ODEs) using similarity transformation. The results for both the velocity and temperature profiles of Jeffrey hybrid nanofluids (Deborah number, β) as well as the skin friction and Nusselt number are presented graphically and in tabulated form. The result shows that the momentum boundary layer thickness is decrease for any increment of the value alignment angle of the magnetic field parameter, the interaction of the magnetic field parameter, alignment angle of the incline plate, the mixed convection parameter, the radiation parameter, and the nanoparticles shape except the value of the volume fraction of the nanoparticles for the increasing value of Deborah number (β). The skin friction is increases as any increment value of an alignment angle of magnetic field, interaction of magnetic parameter, radiation parameter and volume fraction of nanoparticles increase, while the Nusselt number is decrease for the value of radiation parameter. It also observed that the factor of nanoparticles shape result is significant with the Jeffrey hybrid nanofluids which is the nanoparticles shape with the highest skin friction coefficient and Nusselt number is blades shape.

“…In the first stream, the object-oriented paradigm has been used for analogy to the manufacturing physical system, for knowledge representation, or as a programming methodology to develop non-intelligent non-distributed systems [2][3][4][5][6][7][8][9][10][11][12][13].…”

The intelligent agent object (IAO) system is a multi‐paradigm development environment which can be used to create intelligent agent systems for manufacturing or other domains. The IAO system was developed from the rule‐based object (RBO) system which is a programming environment integrating both the rule‐based and object‐oriented paradigms. Propagation‐oriented programming, access‐oriented programming and group‐oriented programming are among the extensions included in the IAO system. Its most unusual contribution is the propagation‐oriented programming paradigm which is not found in most systems. A key application is the messenger inferencing structure which is a user‐extendable framework supporting multiple knowledge representation, meta‐inference control, and distributed inference. This allows the IAO system to go beyond predicate logic based production rule programming. New developments are also introduced for access‐oriented programming. The IAO system can be used to develop integrated manufacturing systems such as the prototype automated guided vehicle planning and control system, which is briefly described.

“…Like its predecessor SmartSim (Ulgen and Thomasma, 1986, 1987a, 1987b, Thomasma and Ulgen 1988, it is based on the objectoriented programming language Smalltalk, but it also provides an environment for description of new objects and new behaviors without any programming.…”

“…Programmer-free simulation environments based on object-oriented languages such as Smalltalk (Knapp 1986, Ulgen and Thomasma 1986, 1987a, 1987b, Thomasma and Ulgen 1987, 1988 are much easier to extend due to their class/object/message and inheritance structures but still require a programmer to incorporate the new behavior or object into the environment.…”

Simulation Program Generators (SPGs) developed using object-oriented environments may be designed to have a number of capabilities not available in traditional SPGs.One such capability is the description of an object's behavior from scratch without any programming when such behavior does not exist in the knowledgebase of the SPG.SmarterSim is an SPG that is currently being developed to provide the user a number of objectoriented tools including libraries of elemental operations, actions/requests, states, and rules and a number of function block templates to create new behavior using the existing primitive elements.The behavior of objects in a robotic manufacturing cell is described using SmarterSim.Like its predecessor SmartSim, SmarterSim supports a hierarchical, modular modeling for building of subsystems (coupled models) from model objects (atomic models) using subsystem management features. The paper also discusses the use of object oriented environments for traditional SPGs and simulation programming languages.
