...Information Infrastructure and Policy 6 (2000) 157–170 IOS Press 157 Accessing Geographical Information Systems over the World Wide Web: Improving public participation in environmental decision-making Steve Carver, Andy Evans, Richard Kingston and Ian Turton School of Geography, University of Leeds, Leeds, LS2 9JT, UK Abstract. This paper describes work carried out as part of the Economic and Social Research Council’s Virtual Society? Research Programme and presents some initial developments in the field of spatial decision support systems (SDSS) on the World Wide Web (WWW). Particular attention is paid to the development of Geographical Information Systems (GIS) and webbased SDSS with the principal aim of increasing public involvement in environmental decision-making. Discussion focuses on public access issues and the implications for online approaches to public participation. Examples of three online SDSS are given covering local, regional and national scale case studies. 1. Introduction The rise of the Internet and the WWW has created many opportunities for those involved in GIS and decision support research. In the last few years many GIS have appeared on the WWW giving the general public, or at least those with a connection to it, access to both GIS and spatial data. With this increased availability, previous criticism of GIS as an elitist technology voiced by Pickles [6] may no longer be valid. We are now beginning to witness the popularising of GIS, at least...

...information to share. The basic Web site is built with HTML, and then creatively enhanced with CSS. To create a visually expressive Web site that can attract thousands of visitors each day you need to use more than HTML and decide what the site contains. There are different languages that can be used to add a sense of style to your site, some of the possible devices are JavaScript, Java, DOM, and AJAX. In the following paper our team will discuss a few examples of how each can be used in Web development. Comparison of Java and JavaScript Java and JavaScript are both object-oriented languages (Burns, 2012). Knowing how to use one language often becomes confusing when attempting to learn the other. Some of the differences between the two are that Java applets can create stand-alone applications that work across platforms running as standalone programs. However, JavaScript cannot create these stand-alone applications and reside on an Internet browser. A programmer must compile Java code before the program can run. This requires an outside program just to compile the code. A compiler turns Java code into machine language code before a browser can interpret it. Any changes the programmer makes to the code will require him to recompile the program and this can be a real tedious act to commit over and over. A web designer can write JavaScript functions directly in a text editor, saving the file and upload it to the server for immediate execution or using an editor like Adobe...

...COMPUTER GRAPHICS Using Java CS 171G Outline • Terminology • Java Graphics Coordinate System • Java Applets • Drawing a Line • Changing the Color • Designing Your Own Colors • Drawing other shapes: rectangles, ovals, arcs, and polygons 1 Terminology: pixel • A pixel is the smallest visual element on a computer screen. Essentially, it’s a dot. • The image shown here is the letter S drawn in an area of 20 X 20 square pixels • The more pixels in an image, the smoother the image will appear. Terminology: resolution • Resolution: the number of pixels that can be displayed on a computer monitor. • When the resolution of a monitor is increased, pixels are smaller and closer together, so images appear smaller. • Typical computer monitor and HD television screen resolutions these days are • 720p: means 1366 pixels across by 768 pixels down • 900p: means 1600 pixels across by 900 pixels down • 1080p: means 1920 pixels across by 1080 pixels down All of the above are used in HDTVs and newer LCD displays (computer screens). 2 Resolution: Example of 900p 1600 pixels 900 pixels This screen has a total of 1,440,000 pixels Cartesian Coordinates • In math class, you learned about the Cartesian coordinate system. – Uses X (horizontal) and Y (vertical) axes – (0, 0) is at the center (also called the origin) – An increase in X means moving to the right – An increase in Y means moving up. – The Cartesian coordinate system has both positive and negative...

...and lastly to the Internet, one thing has been a constant, different languages evolved based on a need. For these two languages, the Internet was a perfect fit, and without them the Internet would be a less dynamic and vibrant highway. As the Internet grew, more and more people found it a more viable place to do business. With that came a need for languages that were fairly easy to learn, dynamic, secure, portable, and maintainable. The industry answered that call with languages such as Java and JavaScript. This paper will perform an analysis of both Java and JavaScript. In order for the reader to gain a better understanding of these languages, the history of these languages with overviews will be presented along with a discussion of the benefits and drawbacks. The History of Java In the middle of May 1995 Java was introduced into the world, and along with Netscape it would be the new way for Internet users to access this new information superhighway. But before it got to this point, Java technology was developed almost by accident. Back in 1991, Sun Microsystems was looking into the future in anticipation of the future of computing, and they tasked a team that became know as the “Green Project”. Their main focus was to come up with a plan for the future of computing, but what they came out with was something quite unexpected. Under the guidance of James Gosling, a team was locked away in an external site to work on the project that would define Sun’s technology direction...

A Practical Method for Watermarking Java Programs Akito Monden Graduate School of Information Science, Nara Institute of Science and Technology akito-m@is.aist-nara.ac.jp Hajimu Iida Information Technology Center, Nara Institute of Science and Technology iida@is.aist-nara.ac.jp Ken-ichi Matsumoto Graduate School of Information Science, Nara Institute of Science and Technology matumoto@is.aist-nara.ac.jp Katsuro Inoue Graduate School of Engineering and Science, Osaka University inoue@ics.es.osaka-u.ac.jp Koji Torii Nara Institute of Science and Technology torii@is.aist-nara.ac.jp Abstract viewers[6][22]. As shown in figure 1, class viewers expose the internals of a class file, displaying class structure (fields and methods), thus, program users may know how to use that class file without asking to the original programmer. To make matters worse, program users can obtain source codes of a class file by using Java decompilers[15], such as SourceAgain[2], Jad[14], Mocha[24], etc. In this situation, the Java program developer’s intellectual property will be infringed if a program user steals anyone else’s class file and builds it into his/her own program without the original programmer's permission. We call this copyright infringement a program theft, which is one of the reasons why many companies hesitate to use Java in the real software development. Although we have copyright law to prohibit...

...computer program. Dallas Semiconductor is developing a new Java-based, computerized ring that will automatically unlock doors and log on to computers. This mobile computer can become even more secure. You can keep the iButton with you wherever you go by wearing it as a closely guarded accessory - a watch, a key chain, a wallet, a ring - something you have spend your entire life practising how not to lose. Here are a few reasons why you might want to wear the iButton in the accessory that best fits your life style : ◆ It is a safe place to keep the private keys to conduct transactions. ◆ It overcomes the deficiencies of the secret password. ◆ You eliminate keystroke with a quick, intentional press of the Blue Dot. ◆ You keep your computer at hand versus lugging your everywhere you roam ◆ You become part of the network economy ◆ This steel-bound credential stands up to the hard knocks of everyday wear, including sessions in the swimming pool or clothes washer What is Java Ring? A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user, a sort of smart card that is wearable on a finger. Sun Microsystem's Java Ring was introduced at their JavaOne Conference in 1998 and, instead of a gemstone, contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built...

...November 30, 2011 Java Security Jessica Shaw: 628 Robert Grimsley: 596 Java is a programming language developed by Sun Microsystems in 1995, which is now called Oracle. The language itself is derived from the languages C and C++. Java is a simple language compared to C and C++; however they are all object-oriented languages. The language was designed to help minimize the amount of space and take up as little of your computer’s hardware resources as possible. The language was designed upon five key goals, and they are as followed: * It should be "simple, object-oriented and familiar" * It should be "robust and secure" * It should be "architecture-neutral and portable" * It should execute with "high performance" * It should be "interpreted, threaded, and dynamic" Java is used for a multitude of things. Java allows one to play virtual video games, view and design 3D photos, and many other interactive topics on the internet. Java is the main programming language for mobile devices as well as smart phones such as Android by google. Java is a very secure and reliable language that is used by over 800 billion people. Without the Java languages there are millions of applets and interactive applications on websites that wouldn’t preform properly without it. Java is compiled by byte code that allows for the program to be run through the Java Virtual Machine, or JVM. The compiling method allows for...

...Assignment 8: Distributed Databases The reason for writing this paper is to clarify the importance of distributed database and why national chain restaurant should implement it. Given the situation presented in the assignment a small restaurant has grown to become a national restaurant chain and now they are concerning more on the distribution of data among different sites chains. For this approach distributed database architecture is suggested and reasons to implement the distributed database I will explain throughout the rest of this paper. The three reasons why an organization may have a need for distributed databases and best practices for implementation of distributed database would be that it provides the distributed transaction management. It provides the provision to do the distributed transactions like select, update and delete on the data without worrying about concurrency or locking problems and they distributed database are independent of given hardware. Today’s world involves a diversity of different machines like Sun machines, PCs, IBM machines, HP machines, and workstations of various kinds. In distributed DBMS all these machines are able to incorporate the data on all of those systems. The plan is to be able to run the same DBMS on a different hardware platform. Operating system independence distribute DBMS is independent of the underlying operating system like UNIX, Linux, Sun Solaris or Windows. All the databases in this model are compatible with different...
