Mobile Device Application Essay Example for Free

Mobile Device Application Essay Java ME, in particular MIDP and CLDC specifications and Mobile device hardware Java is also referred to as a programming environment oriented to the server and it is based on a number of technologies which constitutes the Java 2 Enterprise Edition (J2EE). Such technologies include servlets, JavaServer pages (JSPs), and Enterprise JavaBeans (EJBs). Nowadays, Java is officially known as Java 2 platform and it is divided into three distinct editions: Java 2 Enterprise Edition (J2EE), Java 2 Standard Edition (J2SE), and Java 2 Micro Edition (J2ME). Java 2 Micro Edition (J2ME) has three concepts, namely profiles, configurations, and optional packages. All of them determine Java features applicable, available application programming interfaces, and the form in which applications are packaged. J2ME has two configurations: Connected Limited Device Configuration (CLDC) and Connected Device Configuration (CDC). CLDC is designed for mobile devices with slow processors (Enrique Eric 2001 pp. 28- 45). There are two versions of CLDC: versions 1. 0 and 1. 1. CLDC specifies the ability of Java virtual machine, a small subset of J2SE 1. 3 classes, and a set of application programming interfaces for output/input which is also called Generic Connection Framework. However, CLDC is limiting programming platform as it does not specify the user interface classes. Hence, alternative classes that are defined by J2ME profile are required and such include MIDP to accomplish anything substantial. Java runtime environments for devices such as pagers, resource-challenged handheld devices, and cell phones is defined by Mobile Information Device Profile (MIDP). MIDP target devices are characterized by ample memory to run its applications, bit-addressable display (96*56 pixels), touch screen, and two-way wireless enhanced networking. There exist two versions of MIDP which are defined by Java Community Process and include Java Specification Request 37 (MIDP 1. 0) and Java Specification Request 118 (MIDP 2. 0). Nevertheless, most of the devices in the market apply MIDP 1. Besides, MIDP 1 does not provide standards for interfacing to the phonebook in a device and synchronization of data. In particular, MIDP specifications are silent in one area: ‘how MIDP applications are loaded onto a device and how they are activated or deactivated’ (Enrique Eric 2001 pp. 40-68). Record Management System and MIDlet methods Record management system is a key subsystem of the Mobile Information Device Profile and is an application programming interface. Besides, Record Management system provides a persistence on-device data. Therefore, Record Management System acts as the sole facility for storing data locally –record store. Reason being only a couple of mobile devices sustains a conventional system of files. The MIDP Record Management System facilitates a way in which application data is stored to ensure that it persists across MIDlet. Record Management System is a simp0le database with a row comprised of two columns. One is a unique row identifier while the other contains a sequence of bytes that represents record data. Record stores are identified by a special name which consists of 32 characters in every MIDlet suite. There are a number of MIDlets applicable in the record store. First, ReadWrite MIDlet is creates record store, write down records into persistent storage and reads them, and deletes the record store while exiting. This MIDlet has convenience methods which opens, closes, and deletes record stores. Secondly, IntegerSort MIDlet is used to retrieve records and sort them on basis of their integer value within each record. Nevertheless, its codes do not have a distinct difference from the previous MIDlets. The only additional features are ways of ‘extracting appropriate fields, real sorting, and the comparator image class’. Integer Class MIDlet establishes a sort order by different integers and every record passed through has various Java data. Lastly, is the StringSearch MIDlet which enables searching for records in the Record Management System and it also beefs-up the User Interface. In creating a UI, a text filed, form, and two commands are established. Upon activation, all tasks are executed within the CommandAction ( ) method. Consequently, upon request of CmFind command, SearchRecordstore ( ) initiates searching and it involves assigning SearchFilter ( ) class instance which associates it with record enumeration object Enrique Eric 2001). Sprites basics (Image Sets and Tools Class) and package classes (Graphics class) Spites basics animation in Java can be written in frame animation, sprite animation, and/or both of the two. Mostly, these are used to write mobile enabled application games. There are a number of classes which are important to learn in order to understand Java programming and in particular the sprite animation. These include the Toolkit, Image, Graphics, Random, and Media Tracker. Image class is regarded as the super class when compared with the others and it represents graphical images. Besides, images have to be obtained in a platform specific manner (Richard, 2001). The fact that image is an abstract class makes it impossible to instantiate objects in this class, and besides objects of type image are obtained by applying a roundabout approach. Hence, it makes use of tool kit class. In regard to tool toolkit class, it is probable access system-dependent resources by making use of system their unique codes. In the Graphics class [cite page 8] there are two variables but of particular importance is the Graphics reference type as shown below. Figure 1. The Graphics class. private Graphics offScreenGraphicsCtx; private Thread animationThread; Listing 2 Note: Richard, GB, 2001, Fun with Java: Sprite Animation, Part 1 It refers to an object that serves as an off-screen graphics context and ‘is an area of memory that serves as a stand-in for the computer screen’. It facilitates to rapidly blast pictures from the off-screen Graphics context onto the actual computer screen. As this process does not interfere with the visible image when creating pictures, it renders a ‘smoother animation which can be achieved by creating and drawing the pictures directly on the computer screen’. Thus, it does away with possible distractions and flashing. Graphics class makes provisions for methods which can be applied to draw pictures on a graphics context (Richard, 2001). Development environments for the Windows phone, the Apple iPhone, the Google Android platforms and Location Based Services (LBC). Mobile application development involves a process in which in-built and downloaded applications are developed for hand-held devices suh as cell phones and personal digital assistants. The windows mobile development requires C/ C++ programming language. Visual Studio is nevertheless the most reliable development environment for creating testing, and deploying applications in the Microsoft Windows platform. Besides, this Visual Studio facilitates ample support for the development of Windows Mobile applications. To develop mobile applications, Visual Studio 2005 Edition and Visual Studio Professional Edition are required. Mobile Software Development Kits are freely available but they are dependent on device format and platform. Besides, these Software Development Kits are unique for every every family of Windows Mobile Phone (Enrique Eric 2001). Google Android is an operating system that serves as a platform for mobile applications. The necessary programming language for Android is Java although it is important for the developer to be knowledgeable in XML. In addition one requires Eclipse IDE and to work in Microsoft Windows, Mac OSX, or Linux environments. Android Software Development Kit comprises of: Developer tools such Android Asset Packaging Tool, Android Debug Bridge, Dalvik Debug Monitor Service; Emulator and system images that represents Android operating system; Documentation Sample Code that contains API programming guidelines; Integrated Development environment Support which uses Eclipse IDE as it has special plug-ins (Android Development Tool –speeds up testing process, enables User Interface, application description, and graphical representations). Location Based Services offers mobile phone users a personalized service in order to establish their current physical location. Location API for J2ME (JSR179) is a generic API used to develop Location Based Services. J2ME Location API specification identifies javax. microedition. location which is a discretionary package that facilitates software developers to write wireless Local Based applications for resource-limited mobile devices. JSR179 entails Connected Device Configuration or CLDC version 1. 1 and the type of hardware platform determines applicable location methods (Enrique Eric 2001 PP. 20-39). To develop operating system for iphone, one requires working on a Mac OSX computer that runs X code tools. X code is suite that provides support for project management, building executables, code editing, source-level debugging, and performance tuning others. X-code application provides the foundation source-code development environment and besides x-code is the only probable tool to use in creating iphone applications. As mentioned earlier, iphone Software Development Kit runs only on Mac environment that have installed Intel processors (Enrique Eric 2001 PP. 40-50).

The Impact of Technology Upon Education Essay -- Mainstreaming Technol

The Impact of Technology Upon Education As the years go on, technology has become such a necessity to everyday life in the average person’s life. Whether you live here, there, or anywhere, technology is apparent and has become such an integral part of everyday life to the point that we cannot imagine life without it. Technology is used in both the private and the public life of every person. In private lives we have our computers, our microwaves, our palm pilots, ovens, TVs, cell phones, VCRs, DVD players and much, much more. In our public lives we have checkout scanners, security cameras, security alarms, car alarms, and so much more. What many of us do not realize is that another benefit of technology is helpful with the growing rate of inclusion. There are so many products out on the market today to help disabled people to integrate with the mainstream and have the same benefits as we do. One of the most interesting pieces of technology that I have found for disabled people is iCommunicator. This product is mainly used for the deaf and hard of hearing so that they would not always have to have a translator. It gives them more independence in the workplace or at school. It also has been used with children as young as preschoolers to determine the literacy development and as an early diagnosis for hearing loss in young children. This program converts speech to text, speech to video sign language, speech to computer-generated voice, text to computer-generated voice or video sign language. This program has a speech -to-text translation rate of a 90% greater accuracy in less time than its predecessors. [1] Its remarkable features include auto save, menus, on screen buttons, a vocabulary library that includes m... ...udents. The children whether they be blind, deaf, learning disabled etc now have ways to connect with other people and will be able to fit into the rest of society much easier and finding a job when he or she gets older will not be such a big problem. So many of the original obstacles have been overcome due to the increase of technology. Technology has become a great asset to teaching others and aiding people to do things they had never thought possible, whether it be a blind or deaf person getting an office job, or getting an ‘A’ if you were a learning disabled student. I never knew that there were so many products available on the common market to help those people to integrate with the mainstream population both in school and at the workplace. Technology has definitely become a positive tool for not only the mainstream public but for the disabled as well.

Japanese economic history

In the history of Japanese economy is for 17 years from 1920 to 1937. Japanese economy will be hit by three big depressions, reactionary depression (1920 depression), ? Financial crisis, and ? Shows Depression, after the war [ ? ], and will experience long-term depression in this period. The one-eyed postwar reactionary depression which occurred for 1920 (Taoist 9) years Is the depression which made the cause the economical gap of during the war and the postwar period.As for the Japanese economy of the ass, a protracted economic slump will continue starting with this depression. The global supply shortage of 1920 previous World War I (1914 o 18 years) made Japan's export expand, and It led It to prosperity. Expansion of demand changed Japan from the agricultural country of prewar days to the Industrialized country. Moreover, the labor shortage by expanding demand moved the farmer to the city, and supported city development greatly.However, when World War I held the end of the war and It entered In the ass, Western countries reorganized domestic production and It reduced the demand to Japan. In Dalton to the reduced demand from Western countries, an excess of imports by resumption of import decreased the Japanese specie, and caused the fall of a money order and outstations on commodities. In this way, Japanese economy will fall into a protracted economic slump. Moreover, this depression will deal a blow to many companies, and will drive them in to a breakdown.Moreover, although a return of the gold standard by the lifting of the gold embargo was desired as a measure against reactionary depression, a ban was not removed on the bank or foreign trade business which were faced with the dormant capital at this time. (After World War l, the countries of many including the united States returned to the gold standard one after another, and formed the axis of new international finance. Then, the Great Kant Earthquake occurred for 1923 (Taoist 12) years, and an excess of imports became increasingly large so that this might be attacked.The government proclaimed the Bank of Japan earthquake bill discount-lost â€Å"the government compensates a loss of the Bank of Japan for less than 100 million yen at the same time the Bank of Japan does rediscover influence of the note (earthquake bill) whose earthquake disaster victim is an obligator and it postpones collection† as a measure to the company which suffered the serious damage caused by an earthquake disaster. However, the earthquake bill recessing problem arose by this Imperial edict.In the note processed as this earthquake note, many notes of the company and the manager who became bad loans under the influence of reactionary depression were Intermingled. It Is [ In / In order to prevent the breakdown of the company by this, or a bank / an every place considered as 2 million yen or more In the case of the bank which has a head office In a big city these standards It cannot fill, either a duty of a bank was Imposed so that capital Increase and a merger might be performed wealth five years and the standard might be reached † It went Into effect and Inland banks were cut down.However, by Improper language disturbance of Finance Minister Kate after the Tokyo Waterman bank is actually closed, the bank commission by the depositor banks were obliged to closure and also had the bank which results even in a breakdown. This depression that occurred for 1927 (Shows 2) years is the second financial crisis. It was continuously hit by two depressions after the war with reactionary depression and a financial crisis, and in order to reorganize the Japanese economy which the foreign outflow of the specie was aggravating, Minister-of-FinanceJunketed Onion of the Coach's Humanistic civil administration intermarry big building pushed the lifting of the gold embargo. It is ordered in the basis of Junketed Onion who performs a tight financing policy, and 1929 in the lifting of the gold em bargo (â€Å"Finance Ministry Ordinance of the purport that a ban is removed on gold export from January [ next year ] 1 1 and Japan also makes the gold standard return at last after the war.However, the business of the United States which began to lead the world instead of Britain retreated, and when the New York Stock Exchange slumped n connection with it, the global Great Depression occurred after the war. In this way, Japan will be involved in the global Great Depression simultaneously with the lifting of the gold embargo. This is Shows Depression which occurred for the third 1930 (Shows 5) year. Moreover, in industry, the silk industry in which the demand from the United States occupied most suffered the damage caused by this Shows Depression most.Then, social problems, such as unemployment, selling themselves, and an undernourished schoolchild, also occurred, and the Japanese held economical / social uneasiness and were troubled with poverty. Aiming at escape from this Great Depression, Minister-of-Finance Kookier Dashiki of the Toughs Incubi Friends of Constitutional Government Party Cabinet starts an expansionist fiscal policy. First, Dashiki re-forbade export of gold in 1931, after Britain stopped the gold standard.The managed currency system and red-ink bond which were newly introduced instead of the gold standard and which are not bound by the quantity possessed of a specie enabled reservation of the source of revenue stabilized for performing an expansionist fiscal policy. Dashiki performs the â€Å"spending policy† which plans economic recovery by expanding annual expenditure based on these goods. The war expenditure expanded by the Manchuria Incident which broke out in Shows Depression in 1931 made the annual expenditure by the government increase.This annual expenditure that increased, I. E. , an effective demand, increased the demand for fund of private enterprises, and it led Japanese economy to inflation. The demand for fund of privat e enterprises is connected to the employment to Jobless people, and Japanese economy began to incline to prosperity. However, superfluous circulation of the inconvertible paper money by the red-ink bond and managed currency system which continue increasing will depreciate the exchange rate of the yen, and we will be anxious about a vicious inflation.To this, although Dashiki aimed at reduction of a red-ink bond and a war expenditure, he was assassinated. Although Minister-of-Finance riding ground ? 1 of the successor Koki Horror new Cabinet performed reduction of the public loan, expansion of the war expenditure was continued. Although the demand to heavy and chemical industries also increases with war expenditure expansion, since it did not catch up with it, the controlled economy (â€Å"direct intervention to a governmental economic process†) will start.In this way, the Japanese economy in accomplished high including a spending policy, though the blow was received in three big depressions.

Essay on Humorous Wedding Speech by Brother of the Groom

Humorous Wedding Speech by Brother of the Groom Good afternoon, Ladies and Gentleman – It’s my job to reply to the toast to the bridesmaids and in doing so, say a couple of nice things about George. You know, tell you about some of his good points. The problem is he doesn’t have any good points. Well, except for being naturally gifted at sports. We do, after all, come from the same gene pull. So, on behalf of the bridesmaid, Claire, I would like to start by thanking George for his kind words. I am sure you will all agree that she looks wonderful today, as always. And so does the bride, Peggy - stunning, as always. And, for a change, George has scrubbed up quite nicely too. He looks very refreshed, dont you think? I feel I can†¦show more content†¦The truth is, George has and always will be the prototypical big brother. All through my life, he has blazed trails for me. In school, I would always be greeted by new teachers with the comment, I remember your brother - he was my student and a great guy, or, I hope you are as well mannered as your brother, or, Will you be taking over the role as the school idiot now your brother has left?. But in all seriousness, following in someones footsteps is never easy, but the paths that my brother paved for me made it particularly difficult. A story I want to share with you about my dear brother took place about eight years ago. After a night on the tiles, George returned home and went straight to bed. After a short while, he started feeling a little bit nauseous and, in a moment of drunken clarity, opted to vomit out of his bedroom window. This isnt as foolish as it sounds, because the garage roof protruded under Georges room. So, rather than stain his carpet and surely be caught in the morning, he hoped the roof and gutter would bear the brunt of the evidence of a very drunk young man until the following day, when it could easily be washed away. A great strategy you may think, but it had a one fatal flaw. The force with which George heaved far overshot both the garage roof and the gutter, but was just enough to land squarely on the windscreen of dads car.
