Welcome to Computer Basics
Computer Basics Instructor's Guide 1 COMPUTER BASICS To the Instructor Because of time constraints and an understanding that the trainees will probably come to the course with widely varying skills levels, the focus of this component is only on the basics. Hence, the course begins with instruction on computer components and peripheral devices, and restricts further instruction to the three most widely used software areas: the windows operating system, word processing and using the Internet. The course uses lectures, interactive activities, and exercises at the computer to assure accomplishment of stated goals and objectives. Because of the complexity of the computer and the initial fear experienced by so many, instructor dedication and patience are vital to the success of the trainee in this course. It is expected that many of the trainees will begin at “ground zero,” but all should have developed a certain level of proficiency in using the computer, by the end of the course. 2 COMPUTER BASICS Overview Computers have become an essential part of today's workplace. Employees must know computer basics to accomplish their daily tasks. This mini course was developed with the beginner in mind and is designed to provide WTP trainees with basic knowledge of computer hardware, some software applications, basic knowledge of how a computer works, and to give them hands-on experience in its use. The course is designed to “answer such basic questions as what personal computers are and what they can do,” and to assist WTP trainees in mastering the basics. The PC Novice dictionary defines a computer as a machine that accepts input, processes it according to specified rules, and produces output. -
An INTRODUCTION to Preconstruction (Webt)
WELCOME to an INTRODUCTION TO Preconstruction (webT) Welcome to the Preconstruction (webT) User Guide. When development of the Preconstruction application is complete, it will be a self-contained, electronic database application that will deal with everything currently handled by CES, PES, LAS, Designer Interface, Expedite, Bid Express, DSS and Sitemanager. The purpose of this series of documents is to provide a simple and easy explanation dealing with navigating and working in the new web Preconstruction environment. It should answer the “WHO, WHAT, WHEN, WHERE, WHY and HOW” of webT. It is designed to provide easy-to-follow steps to enhance the accomplishment of your tasks whether your job deals with contract administration, project design, estimation, contract awarding or contract management, to mention just a few. The instructions and directions are arranged logically and sequentially. The goal of this User Guide is to reduce the frustration frequently associated with learning a new application. The guide should be a handy reference that is quick and easy. If you find it doesn’t provide enough information, please call the HELP DESK or even reference the “Online Help” available throughout the application The Guide is intended to be a quick reference on how to accomplish certain tasks without a lot of technical jargon. It is not intended to be a technical treatise that defines the coding and programming challenges handled by the application. Part of the beauty of a web application is the ease in which tasks are accomplished without requiring the user to remember special keys or to enter special codes. With the aid of drop-down menus and mouse clicks on buttons or hyperlinks, processes can be activated and run without the user doing anything more complicated than a point and click. -

ABSTRACT The use of vegetation in remediating contaminated soils and sediments has been researched for a number of years. Positive laboratory results have lead to the use of vegetation at field sites. The design process involved with field sites and the associated decision processes are being developed. As part of this develop- ment, a computer-based graphical user interface decision support system was designed for use by practicing environmental professionals. The steps involved in designing the graphical user interface, incorporation of the contaminant degradation model, and development of the decision support system are presented. Key words: phytoremediation, simulation INTRODUCTION Vegetation has been shown to increase the degradation of petroleum and organic contaminants in contaminated soils. Laboratory experiments have shown promising results which has led to the deployment of vegetation in field trials. The design of field trials is different than the design of a treatment system. In a field trial, the type of vegetation, use of amendments, placement and division of plots, and monitoring requirements are geared toward producing statistically measurable results. -

Understanding the User Interface
CHAPTER 2 Understanding the User Interface This chapter introduces the Cisco Identity Service Engine (ISE) user interface in the following topics: • Inherent Usability, page 2-1 • Elements of the User Interface, page 2-2 • Introducing the Dashboard, page 2-6 • Common User Interface Patterns, page 2-10 • Understanding the Impact of Roles and Admin Groups, page 2-12 Inherent Usability The Cisco ISE user interface centralizes network identity management, while providing drill-down access to granular data across the network. The Cisco ISE user interface makes it easier for you to get the information you need to make critical decisions in a timely fashion by providing the following: • Data based on user roles and their respective tasks • A centralized administration workspace • At-a-glance statistics for monitoring networkwide health and security • Simplified visualizations of complex data Functional User Interface The Cisco ISE user interface is role-based and tailored to your job function. Elements that are associated with tasks that are outside of your job description are deactivated or not shown at all. Menu structures within the user interface link roles to job functions, thereby determining the available permissions. It is possible to be assigned to multiple roles, depending on the nature of your job. For more information, see Understanding the Impact of Roles and Admin Groups, page 2-12. Centralizing the Administration The Cisco ISE user interface allows you to perform all necessary network administration tasks from one window. The Cisco ISE home page, also known as the dashboard, is the landing page, displaying real-time monitoring and troubleshooting data. -

Despite many future additions Two groups of participants (novice and advanced) completed a and improvements, the D-Pad persists on all standard controllers study comparing a prototype game controller to a standard game for all consoles introduced after the NES. controller for point-select tasks. The prototype game controller Shortcomings of the D-Pad became apparent with the introduction replaces the right analog stick of a standard game controller (used of 3D games. The Sony PlayStation and the Sega Saturn, for pointing and camera control) with a trackball. We used Fitts’ introduced in 1995, supported 3D environments and third-person law as per ISO 9241-9 to evaluate the pointing performance of perspectives. The controllers for those consoles, which used D- both controllers. In the novice group, the trackball controller’s Pads, were not well suited for 3D, since navigation was difficult. throughput was 2.69 bps – 60.1% higher than the 1.68 bps The main issue was that game characters could only move in eight observed for the standard controller. In the advanced group the directions using the D-Pad. To overcome this, some games, such trackball controller’s throughput was 3.19 bps – 58.7% higher than the 2.01 bps observed for the standard controller. Although as Resident Evil, used the forward and back directions of the D- the trackball controller performed better in terms of throughput, Pad to move the character, and the left and right directions for pointer path was more direct with the standard controller.
