The Document Object Model (DOM) is an important part of creating animation and making web pages interactive. The Document Object Model is used with Dynamic HTML to help accomplish the interactive web pages that are used today. “Dynamic HTML(DHTML) refers to a combination of technologies that make Web pages dynamic…a combination of JavaScript, XHTML, CSS, and the Document Object Model” (Gosselin, 2008, pg. 485). The Document object Model is all the HTML that is displayed on a web page from the web browser. Each of the many elements contained in the web page are considered objects and can be controlled and changed by using JavaScript. The Document object Model gives you the ability to change these elements without the web page needed to be reloaded. The HTML DOM can be used to dynamically change the document object and to change and control elements like images, which can themselves be considered the image object. The Document object and the image object both contain methods and properties that can be used to dynamically change the web page. The methods used with the document object are close, open, getElementById, getElementsByName, getElementsByTagName, write and writeIn. The open method creates a new window or a frame. The close method closes the document that was opened with the open method. The getElementById method retrieves an element by the specified ID. The getElementsByName method retrieves an array of elements that have a specific name. The getElementsByTagName method will retrieve all the specified elements with a specific tag name and set them in an array. The write method writes text to the web page. The writeIn method also writes text to the web page but also includes a line break after the text. The properties used with the document object include the anchors, body,…...

...d1.1 Object-oriented programming (OOP) is a programming language model organized around "objects" rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data. Object-oriented programming is a programming paradigm that uses abstraction (in the form of classes and objects) to create models based on the real world environment.   An object-oriented application uses a collection of objects, which communicate by passing messages to request services. Objects are capable of passing messages, receiving messages, and processing data. The aim of object-oriented programming is to try to increase the flexibility and maintainability of programs. Because programs created using an OO language are modular, they can be easier to develop, and are simpler to understand after development. The characteristics of object oriented programming are as follows: 1. Class A class is a blueprint, or prototype, that defines the variables (data) and the methods (operations) common to all objects of a certain kind. 2. Object Objects are the basic run time entities in an object oriented system. They may represent a person, a, place, a bank account, a table of data or any item that the program has to handle. Objects take up space in memory and have an associated address like record in Pascal, or a structure in C. 3. Encapsulation The act of placing data and the operations that......

Example and Explanation * An abstraction is a model of a complex system that includes only the essential details.  * Abstractions are the fundamental way that we manage complexity.  * Different viewers use different abstractions of a particular system. * Thus, while we see a car as a means of transportation, the automotive engineer may see it as a large mass with a small contact area between it and the road. What does abstraction have to do with software development? * The programs we write are abstractions.  * A spreadsheet program used by an accountant models the books used to record debits and credits.  * An educational computer game about wildlife models an ecosystem.  * Writing software is difficult because both the systems we model and the processes we use to develop the software are complex.  * One of our major goals is to convince you to use......

...DATABASE A database is an organized collection of data. The data are typically organized to model aspects of reality in a way that supports processes requiring information. For example, modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. Database management systems (DBMSs) are computer software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL,Microsoft SQL Server, Oracle, SAP and IBM DB2. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such asSQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database modelthat they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language. Sometims a DBMS is loosely referred to as a "database".  database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. In computing, databases are sometimes classified according to their organizational approach. The most...

Document Model Prototypes

...Document Object Model Prototypes, Part 1: Introduction Introduction This article is the first installment of a two-part series that introduces advanced JavaScript techniques in Windows Internet Explorer 8. Web applications have come a long way since the birth of the static Web page. Today, Web developers need improved programming functionality, flexibility, and features to enable them to build the next generation of Web applications. The Internet Explorer Web platform provides many of the features and functionality necessary to build those applications. Where the Web platform's built-in support ends, JavaScript, the principle scripting language used on the Web, is often used to code innovative new features that supplement the Web platform, cater to Web site specific scenarios, normalize differences between browsers, and so on. To further empower Web developers with the programming tools necessary to build new JavaScript scenarios that innovate, extend, and build-upon the Web platform, Internet Explorer 8 offers a collection of features that extend some of JavaScript's advanced functionality into the Document Object Model (DOM). This article provides an overview of JavaScript prototype inheritance and introduces the DOM prototypes feature available in Internet Explorer 8; Part 2 introduces a new type of JavaScript property called an accessor property (or getter/setter property). Prototypes in JavaScript To begin a discussion of DOM prototypes, it is crucial to......

Towards a Model of Engaging Online Students: Lessons from Moocs and Four Policy Document

...International Journal of Information and Education Technology, Vol. 5, No. 6, June 2015 Towards a Model of Engaging Online Students: Lessons from MOOCs and Four Policy Documents Khe Foon Hew  Abstract—The paper describes a model of engaging students in fully online or blended learning environments. To do this, I first discuss the notion of student engagement and how it relates to the Self-Determination Theory of motivation. Next, I reviewed a number of online learning policy guidelines from four professional councils around the world in order to elicit specific guidelines related to the design of online learning courses, and student engagement. Following that, I analyzed two most highly-rated MOOCs. I analyzed the structural features of the two MOOCs and the comments of both participants who completed the courses, and who partially completed or dropped out. Altogether, comments from 839 participants were examined. Finally, using these empirical data and the policy guidelines from the four professional organizations, I outline a rudimentary model of engaging students in online learning courses, based on six major instructional design elements. Index Terms—Online learning, blended learning, massive open online learning, MOOCs, e-learning, instructional design, engagement, motivation, self-determination theory. I. INTRODUCTION Online learning for both students and teachers has become one of the fastest growing trends in educational uses of technology [1]. Essentially, the......

...The watchdog and government According to this document, the conditions of democracy are necessary for an effective media role as watchdog: "the institutional arrangements of democracy provide the most hospitable environment for watchdog reporting. The constitutional and legal protections for a free press as well as access to government-held information give journalists not only the right, but also the tools with which to monitor government." It has taken root in the Balkans, for example, but not in Myanmar. With its turn to market liberalisation, China now has watchdog journalism, fuelled by profitability in the wake of government reductions in subsidies. In addition to political liberalisation, competitive media markets, and degrees of social and political ferment, journalistic and entrepreneurial agency is a factor, fostered by the protection of journalists from physical harm, jail, harassment through lawsuits, and restrictions on access to information. The watchdog and the market: The contradictory nature of the market is described as: "On one hand, market liberalization and competition have encouraged the emergence of, and in many places, also sustained, investigative reporting. But at the same time, market pressures are a major obstacle to its continued viability.” Where donor funding is available, non-profits sometimes take on the watchdog role. "They fill a gap in media systems where market, ownership, or political pressures make investigative reporting by......

...by comparing two images, the reference image and the live traffic image. They improved object detection using image segmentation and noise removal operations. In [2] another technique is proposed to control the traffic signal by using image processing, in which they first selected the reference image which is the image with no vehicles or less vehicles and every time matching real time images with that reference image. On the basis of the percentage of matching traffic lights controlled. But in this technique image matching is performed by the edge detection. The reference subtraction is a complex technique, with limited outcomes. This paper presents a density analyzer scheme based on counting the number of vehicles in the present image, which provides us more accurate information for signal decision making. The paper is organized as follows: section II explains the design of the system. Section III discusses the working of the system. Finally section IV concludes the paper followed by the key references used in the work results followed by the key references used in this work. 2. SYSTEM MODEL The work is divided into 4 parts. The first part is to process the video signal and image acquisition from fixed camera using MATLAB. The second part is to select the target area where the vehicles could be present by using image cropping technique. The third part is the object detection which is performed by enhancing features of the image. Finally,......

...activity into their days, and, consequently, exercise crazes have become a hot topic. From Jane Fonda’s Workout, to Cindy Crawford’s Shape-up; or from Total Gym, to Zumba, to P90X, or yoga, America has been embracing one exercise fad after another for decades. And because each fad seems to require its own unique workout apparel and equipment, several companies have made it the primary focus of their businesses to provide for this ever-growing market. One of the industry leaders in this business model is NIKE. According to NIKE’s official website, by 2011 the company employed over 40,000 people worldwide, and operated in more than 160 countries on six continents around the globe. ("NIKE inc. locations," 2011) The website also says that NIKE’s mission is to “bring inspiration and innovation to every athlete in the world.” ("NIKE inc. locations," 2011) In order to achieve this mission, NIKE supplements its extensive global presence with its online transactional website, in a business model known as the click-and-mortar retailer. NIKE’s cofounder, Bill Bowerman (1911-1999), played a critical role in setting the path that the company would follow. Bowerman is widely considered one of the greatest track and field coaches the world has ever known; in his 24 years at the University of Oregon, he won four NCAA team championships, and coached 33 Olympians, 16 sub-four-minute milers, and 64 All-Americans.
