SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A system model is the conceptual model as a result of system modeling that describes and represents a system. A system comprises multiple views such as planning, requirement (analysis), design, implementation, deployment, structure, behavior, input data, and output data views. A system model is required to describe and represent all these multiple views. The system model describes and represents the multiple views possibly using two different approaches. The first one is the non-architectural approach and the second one is the architectural approach. The non-architectural approach respectively picks a model for each view. For example, Structured Systems Analysis and Design Method (SSADM), picking the Structure Chart (SC) for structure description and the Data Flow Diagram (DFD) for behavior description, is categorized into the non-architectural approach. The architectural approach, instead of picking many heterogeneous and unrelated models, will use only one single coalescence model. For example, System architecture, using the Architecture Description Language (ADL) for both structure and behavior descriptions, is categorized into the architectural approach.

What is DATA MODELING? What does DATA MODELING mean? DATA MODELING meaning - DATA MODELING definition - DATA MODELING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Data modeling in software engineering is the process of creating a data model for an information system by applying formal data modeling techniques. Data modeling is a process used to define and analyze data requirements needed to support the business processes within the scope of corresponding information systems in organizations. Therefore, the process of data modeling involves professional data modelers working closely with business stakeholders, as well as potential users of the information system. There are three different types of data models produced while progressing from requirements to the actual database to be used for the information system. The data requirements are initially recorded as a conceptual data model which is essentially a set of technology independent specifications about the data and is used to discuss initial requirements with the business stakeholders. The conceptual model is then translated into a logical data model, which documents structures of the data that can be implemented in databases. Implementation of one conceptual data model may require multiple logical data models. The last step in data modeling is transforming the logical data model to a physical data model that organizes the data into tables, and accounts for access, performance and storage details. Data modeling defines not just data elements, but also their structures and the relationships between them. Data modeling techniques and methodologies are used to model data in a standard, consistent, predictable manner in order to manage it as a resource. The use of data modeling standards is strongly recommended for all projects requiring a standard means of defining and analyzing data within an organization, e.g., using data modeling: - to assist business analysts, programmers, testers, manual writers, IT package selectors, engineers, managers, related organizations and clients to understand and use an agreed semi-formal model the concepts of the organization and how they relate to one another; - to manage data as a resource; - for the integration of information systems; - for designing databases/data warehouses (aka data repositories). Data modeling may be performed during various types of projects and in multiple phases of projects. Data models are progressive; there is no such thing as the final data model for a business or application. Instead a data model should be considered a living document that will change in response to a changing business. The data models should ideally be stored in a repository so that they can be retrieved, expanded, and edited over time. Whitten et al. (2004) determined two types of data modeling: - Strategic data modeling: This is part of the creation of an information systems strategy, which defines an overall vision and architecture for information systems is defined. Information engineering is a methodology that embraces this approach. - Data modeling during systems analysis: In systems analysis logical data models are created as part of the development of new databases. Data modeling is also used as a technique for detailing business requirements for specific databases. It is sometimes called database modeling because a data model is eventually implemented in a database.

UML Class Diagram Tutorial
 
10:17
Learn how to make classes, attributes, and methods in this UML Class Diagram tutorial. There's also in-depth training and examples on inheritance, aggregation, and composition relationships. UML (or Unified Modeling Language) is a software engineering language that was developed to create a standard way of visualizing the design of a system. And UML Class Diagrams describe the structure of a system by showing the system’s classes and how they relate to one another. This tutorial explains several characteristics of class diagrams. Within a class, there are attributes, methods, visibility, and data types. All of these components help identify a class and explain what it does. There are also several different types of relationships that exist within UML Class Diagrams. Inheritance is when a child class (or subclass) takes on all the attributes and methods of the parent class (or superclass). Association is a very basic relationship where there's no dependency. Aggregation is a relationship where the part can exist outside the whole. And finally, Composition is when a part cannot exist outside the whole. A class would be destroyed if the class it's related to is destroyed.

UML Use Case Diagram Tutorial
 
13:24
Learn how to make Use Case Diagrams in this tutorial. Both beginners and intermediate UML diagrammers will find all the necessary training and examples on systems, actors, use cases, and include and extend relationships. UML Use Case Diagrams show a system or application; then they show the people, organizations, or other systems that interact with it; and finally, they show a basic flow of what the system or application does. This tutorial explains the four main characteristics of Use Case Diagrams: systems, actors, use cases, and relationships. A system is whatever you’re developing. It could be a website, a software component, a business process, an app, or any number of other things. You represent a system with a rectangle. The next aspect of Use Case Diagrams are actors. An actor is going to be someone or something that uses our system to achieve a goal, and they're represented by a stick figure. Use Cases are elements that really start to describe what the system does. They're depicted with an oval shape and they represent an action that accomplishes some sort of task within the system. The final element in Use Case Diagrams are relationships, which show how actors and use cases interact with each other. There are different types of relationships (like association, include, extend, and generalization) that are represented by varying types of lines and arrows. —— Learn more and sign up: http://www.lucidchart.com Follow us: Facebook: https://www.facebook.com/lucidchart Twitter: https://twitter.com/lucidchart Instagram: https://www.instagram.com/lucidchart LinkedIn: https://www.linkedin.com/company/lucidsoftware

Although this course is focused on object oriented systems analysis and design, another technique that is frequently used is structured analysis and design. The Gane and Sarson techniques for data flow diagramming are just as useful for modeling and understanding systems, and in some cases may be even more appropriate than OO methods. You may also find that users and non-technical stakeholders can digest structured models a bit easier than UML models with their complicated syntax.

Using Simscape Power Systems to Simulate Microgrids - Microgrid Development and Analysis, Part 3
 
20:30
In this third video on microgrids, the modeling and simulation of power systems in MATLAB® and Simulink® is introduced with Simscape Power Systems™. See how Simscape Power Systems can be used to schematically represent a one-line microgrid diagram using blocks that represent different distributed energy resources (DERs). The DERs in this example include renewables, such as solar, a diesel GenSet, and an energy storage system (ESS). Using the simple microgrid that is built in this video, you see how desktop simulation can be used to subject the distribution system with residential load changes or unintentional islanding of the microgrid. Load flow analysis in Simscape Power Systems is also introduced. Since microgrid systems commonly have inverter-based controls for solar and ESS, different levels of simulation fidelity can be useful to study the microgrid operation. Simscape Power Systems can be used to simulate Phasor or Electromagnetic Transients (EMT). Depending on the requirements of the simulation study, Phasor, EMT, or a combination of both can be used. An example of a segmented IEEE 123 node network is introduced that illustrates a hybrid Phasor-EMT simulation. In addition to desktop simulation for analysis, you learn how the same desktop simulations can be transferred to a real-time platform for hardware-in-the-loop simulation. This example uses Simulink Real-Time™ and a Speedgoat real-time machine. The Simscape Power Systems model is converted to a C-code representation and then compiled for use on the real-time operating system.

SAP2000 is a structural analysis and design software which uses finite element method. Structural analysis can be defined as the method of finding the result of application of the loads on a structural system in the form of reactions given by the structural components. Structural analysis is helpful in finding force, moment and deflection in the structure. There are various methods of structural analysis such as moment distribution method for finding the moment in various beams of a structural system. However, nowadays, these methods have been replaced by software which make analysis work easier and accurate. Some of the commonly used software are as follows: • SAP 2000 • STAAD PRO • ETABS • SAFE STRAP STRUDS NISA ANSYS MICROSTATION SAP2000 Introduction: https://www.youtube.com/edit?o=U&video_id=oIwlO2S2be4 SAP2000 Modelling: https://www.youtube.com/edit?o=U&video_id=BOdYsb608-Q Watch SAP 2000 Introduction Video at: https://www.youtube.com/watch?v=oIwlO2S2be4&t=7s Install SAP 2000 https://www.youtube.com/watch?v=ZPzgx0m9vs0 Like Us On Facebook: https://www.facebook.com/engi.acad Watch SAP 2000 Introduction Video at: https://www.youtube.com/watch?v=oIwlO2S2be4&t=7s Install SAP 2000 https://www.youtube.com/watch?v=ZPzgx0m9vs0 Like Us On Facebook: https://www.facebook.com/Engineering-Academy-494854860860175/ -~-~~-~~~-~~-~- Please watch: "RCC E03: Design of Beam for Shear[Theory]" https://www.youtube.com/watch?v=8OJGZhR2OlY -~-~~-~~~-~~-~-

Modeling to Understand and Improve Your Brake System - MATLAB and Simulink Racing Lounge
 
14:52
Understand and improve your brake system using modeling. Mohamed Barakat, of ASU Racing Team, and Christoph Hahn, of MathWorks, introduce you to an approach using Simulink where safety is key. A safe and robust braking system is a major component of a Formula Student racecar and in this episode you will learn how to model it, to understand it better and increase performance. All models related to this episode can be found on MATLAB Central FileExchange and a SAE paper has been published providing the opportunity to have a more in-depth look. The core of the brake system is modeled using Simulink, containing all physical components such as the piston and the limiter valve. Moreover, Mohamed has used the results obtained from this model to interface with other simulation tools such as Ansys for more detailed stress analysis. A model validation using a dynamometer showed close agreement (12%) between modeled and real-world deceleration which is really good taking the complexity of the system into account.
