Application User Interface

Transceivers are used to connect nodes to the various Ethernet media. Transceivers, also known as Media Attachment Units (MAUs), attach to the Ethernet cable and provide an Application User Interface (or AUI) connector for the computer. The AUl connector consists of a 15-pin D-shell type connector, female on the computer side and male on the transceiver side. Virtually all Ethernet-compatible computers provide such an AUI connector. The transceiver is generally attached directly to the computer s AUI connector, or the transceiver may be attached to the computer with a specially shielded AUI cable which must be less than 50 m long. In addition to an AUI connector, many computers also contain a built-in transceiver, allowing them to be connected directly to Ethernet without requiring an external transceiver. 

Figure 6 illustrates the five tiers of ERP architectures core/internal (often called data), application, user interface, remote application, and remote user interface. A common intraenterprise scenario involves the data, apphcation, and user interface tiers. This scentuio does not preclude appUcation-to-application interaction. Similarly, common interenterprise scenarios include an internal user or application requesting information from an extemtil application or an external user or apphcation requesting information from an internal apphcation. The Internet is the conduit through which these internal/external exchanges occur. Additionally, in many ERP systems web browsers have emeiged as the platform for both local and remote user interfaces. 

It is user friendly and possesses a graphical user interface for developing the flow paths, ventilation system, and initial conditions. The FIRIN and CFAST modules can be bypassed and temperature, pressure, gas, release energy, mass functions of time specified. FIRAC i.s applicable to any facility (i.e., buildings, tanks, multiple rooms, etc,) with and without ventilation systems. It is applicable to multi species gas mixing or transport problems, as well as aerosol transport problems, FIRAC includes source term models for fires and limitless flow paths, except the FlRlN fire compartment limit of to no more than three... 

Documents should be provided, where possible, as individual Portable Document Format (PDF) files, while Extensible Markup Language (XML) must be used to provide a user interface that enables navigation and viewing via a standard web browser. This offers the potential for an applicant to make a compete submission on... 

Consider Equations (6-10) that represent the CVD reactor problem. This is a boundary value problem in which the dependent variables are velocities (u,V,W), temperature T, and mass fractions Y. The mathematical software is a stand-alone boundary value solver whose first application was to compute the structure of premixed flames.Subsequently, we have applied it to the simulation of well stirred reactors,and now chemical vapor deposition reactors. The user interface to the mathematical software requires that, given an estimate of the dependent variable vector, the user can return the residuals of the governing equations. That is, for arbitrary values of velocity, temperature, and mass fraction, by how much do the left hand sides of Equations (6-10) differ from zero ... 

A different approach is taken by lO-Informatics (www.io-informatics. com), whose Sentient product allows users to manage, analyze, compare, link, and associate data from heterogeneous sources. Instead of creating work-flows, data sources and applications are aggregated upfront in a graphical user interface that allows many kinds of information to be viewed at once, and customized links and queries between them can also be created easily. 

Beginning with SAS 9.1, the SAS XML Mapper (previously known as Atlas) is a SAS stand-alone Java application supplied as part of Base SAS. The SAS XML Mapper is a graphical user interface assistant for building SAS XML Map files. Here is a display that shows the previous example s XML Map file being built from within the XML Mapper application ... 

The user interface, the interpreter, and the inference engine together comprise the ES shell or a skeletal system. As these components are largely independent of the specific application, all that is needed to create a working ES from the shell is to feed it with rules and facts. 

In addition to the Premium Excel Solver and Optquest, there are many other software systems for constrained global optimization see Pinter (1996b), Horst and Pardalos (1995), and Pinter (1999) for further information. Perhaps the most widely used of these is LGO (Pinter, 1999), (Pinter, 2000), which is intended for smooth problems with continuous variables. It is available as an interactive development environment with a graphical user interface under Microsoft Windows, or as a callable library, which can be invoked from an application written by the user in... 

At the business level, it takes a sequence of interactions between client and seminar company, including enquire, schedule, deliver, follow-up, and pay, to together constitute an abstract purchaseCourse action. This sequence has a net effect on both client and seminar company not only has the seminar company delivered a service and gained some revenue, but also the client has paid some fees and gained knowledge. In software, it may take a sequence of low-level operations via the user interfaces (UIs) of multiple applications and databases to complete a scheduleCourse operation. Such a joint action, also called a use case, is the subject of Chapter 4. 

A suitable tool should be able to support the building of models and designs by application of model frameworks. Suppose, for example, that our business model has a type Stock with a numeric attribute level choosing a package of user-interface pieces, we find a type Meter for displaying numeric readings. 

For example, an application that reads stock figures from a newsfeed can be wired up to a spreadsheet this component does some calculations and passes the results to a database, from which a Web server extracts information on demand. Each of these components may be a stand-alone application, perhaps even with its own user interface, but is provided with a way to interact with other software. 

Using a class framework, such as Java s Swing components, to build the user interfaces for many applications and to connect those UIs to their domain objects. 

The effort and ease of dynamically connecting components to compose larger systems, from writing screen-scrapers for host-based systems (discussed in a moment) to creating complex applications by visually configuring and connecting server-side components to one another and to user interfaces. 

The first form led to client-server-styled systems, with the client combining user-interface and application logic and communicating via SQL requests with a database server that dealt with persistence, transactions, security, and so on. All communication involved database processing requests in SQL, and clients did not communicate with one another (except indirectly through shared data on the server). 

You can sometimes make the user interface elements and the application object reusable so that you can create larger panels and application objects such as the following ... 

Other cycles can be horizontal one that does not deliver new user-visible functionality but instead carries a minimal use case through increasingly deep layers of the application and infrastructure components, exercising all communication channels. An example is a single user interaction carried from the user interface through the business object layer via an object request broker (ORB) to the applicable databases and back. 

In terms of the general architecture, the system we have been specifying will be broken into several systems one for each Store plus a head office (HQ) system (see Figure 16.15). In each store, there will be several Application (App) components one for each Desk and one for each of the Manager components specified earlier, which will be driven by the user interfaces. We don t yet know exactly how the HQ system will talk to the Store systems, nor exactly what the communications between the Application and the Managers are.
