Modeling Representation

Cyber-physical systems (CPS) is an exciting emerging research area that has drawn the attention of many researchers. However, the difficulties of computing and physical paradigm introduce a lot of trials while developing CPS, such as incorporation of heterogeneous physical entities, system verification, security assurance, and so on. A common or unified architecture plays an important role in the process of CPS design. This article introduces the architectural modeling representation of CPS. The layers of models are integrated from high level to lower level to get the general Meta model. Architecture captures the essential attributes of a CPS. Despite the rapid growth in IoT and CPS a general principled modeling approach for the systematic development of these new engineering systems is still missing. System modeling is one of the important aspects of developing abstract models of a system wherein, each model represents a different view or perspective of that system. With Unified Modeling Language (UML), the graphical analogy of such complex systems can be successfully presented.

Abstraction Levels

Due to the continuous exponential rise in SoC’s design complexity, there is a critical need to find new seamless methodologies and tools to handle the SoC co-design aspects. We address this issue and propose a novel SoC co-design methodology based on Model Driven Engineering and the MARTE (Modeling and Analysis of Real-Time and Embedded Systems) standard proposed by Object Management Group, to raise the design abstraction levels. Extensions of this standard have enabled us to move from high level specifications to execution platforms such as reconfigurable FPGAs. In this chapter, we present a high level modeling approach that targets modern Network on Chips systems. The overall objective: to perform system modeling at a high abstraction level expressed in Unified Modeling Language (UML); and afterwards, transform these high level models into detailed enriched lower level models in order to automatically generate the necessary code for final FPGA synthesis.

The growing complexity of embedded and cyber-physical systems makes the design of all system components from scratch increasingly impractical. Consequently, already from early stages of a design flow, designers rely on prior experience, which comes in the form of legacy code or third-party intellectual property (IP) blocks. Current approaches partly address the co-simulation problem for specific scenarios in an ad hoc style. This work suggests a general method for co-simulation of heterogeneous IPs with a system modeling and simulation framework. The external IPs can be integrated as high-level models running in an external simulator or as software- and hardware-in-the-loop simulation with minimal effort. Examples of co-simulation scenarios for wrapping models with different semantics are presented together with their practical usage in two case studies. The presented method is also used to formulate a refinement-by-replacement workflow for IP-based system design.

Due to the complex timing sequence of NAND flash, a unified design process is urgently required to guarantee the reliability of storage system of nano-satellite. Unified Modeling Language (UML) is a widely used high level modeling language for object-oriented design. This paper adopts the UML as the design and modelling tool in the low level storage system design to elaborate the UML application in each phase of design in detail. The result shows taking UML as the modelling tool results in a clear and unambiguity design, which promotes the reliability and quality of software. At last, the feasibility of object-oriented implementation in C is presented.

The need for information in life has transformed into basic needs. As an impact, this will cause problems when not handled properly. The Garuda Cooperative is one of the Employee Cooperatives in Sragen with complex managerial data but its management is still manual. To support its business process, a management information system is needed to handle data quickly and accurately. This study aims to develop a management information system for Garuda Cooperatives. The flow of research used is analysis, design, implementation, testing, and conclusion. System modeling uses the Unified Modeling Language (UML) in the form of a use case diagram and statechart diagram. The programming language used is Delphi with PostgreSQL as database management. The information system produced includes processing savings and loan business units, processing membership data and reports. The results of the system testing on 8 respondents showed that the system was running well to meet needs, had an attractive appearance, and was easy to use.

Information technology is rapidly developing all existing activities or activities become very important in determining the progress of the company, both in operational and non-operational activities, one of which is the procurement report which must produce accurate and accurate reports. PT Instaprint Jaya Primatama is a company engaged in the field of digital printing while those who do not yet have a system that uses stock of goods, the current system still has problems such as requiring a long time to find the amount needed Every day and making reports still using Ms. Excel so there is a delay in the company's performance. This study aims to create a system that can support the process of reporting needs that can be done effectively, the design process uses the PIECES method, system modeling using UML (Unified Modeling Language) to use visualization, which can be used by using the Hypertext Preprocessor programming language (PHP ) with a MySQL-Server database as a database. And to collect data, the authors use the method of observation, interviews, and literature study. With the system of preparation of goods, can make it easier for inventory administrators to produce accurate reports with a fast time can be made in order to produce effective and efficient.

Time Required

The System Modeling Language (SysML) used the Requirement Diagram to model non-functional requirements, such as response time, size, or system functionality, which cannot be accommodated in the Unified Modeling Language (UML). SysML Requirement Diagram, in its implementation, integrates with several diagrams describing the requirements, which are referred to as additional elements. The absence of transformation rules for these additional elements to become OWL ontology causes difficulties in reading, understanding, and tracking the requirements. In this research, an extended rule of the Requirement Diagram transformation is proposed to solve the problems. First, some transformation rules are defined to make requirements easier to trace and realize the ontology generation's automatic transformation. Second, the time required during transformation processing to prepare and generate the OWL file shows the proposed model's performance. The ontology components produced from this research, such as class, subclass, object property, and data property, can be viewed in Protégé.

Activities of prominent terrorist groups like Boko Haram, Al-Shabaab, Ansaru, and Ansar Dine have left thousands of people dead and properties destroyed for a number of decades in some developing nations. The high level of insecurity occasioned by operations of terror groups has impacted negatively on the socio-economic development of these nations. On the other hand, the use of mobile devices, such as cell phones, has gained prominence in developing nations over the past two decades. Putting side-by-side these two facts, namely, that the menace of terrorism among some developing nations is alarming and that the use of mobile devices is common among citizens of developing countries, this chapter develops a mobile application prototype called TerrorWatch. TerrorWatch is equipped with relevant menus, buttons, and interfaces that will guide a user on what to do when confronted with a terrorist attack or threat. The unified modeling language (UML) was deployed to design the architecture of the application, while the object-oriented paradigm served in the implementation.
