This thesis is present an UHF REMOTE CONTROL by used radio wave UHF band ( about 304 Megahertz ) . The MC 145026 will encode mine bits of information and serially transmit data ( 0,1, open ) to allow 19683 different codes. The decoders will receive the 9 bit word and will interpret some of the bits as address codes and some as data. When the transmitter sends address codes that match that of the receiver. A valid transmission output will go high on decoder when they recognize an address that matches that of the decoder.

PRESTRESSED CONCRETE DESIGN

2009-09-01T08:07:00.000-07:00

The object of this special project is to pioneer computer aided instruction in the department of civil engineering. Electronic files were gathered and published in a form of Microsoft Word 2000 document and is available for access via the Internet. Students can access and download these files for self-studying or for references. Instructors can present these files on the screen in the classroom in a more effective manner than putting sheet by sheet of transparencies on the overhead projector.

This report consists of two parts The main part contains theories, examples and flowcharts used in the analysis and design of prestressed concrete structures. The design follows Engineering Institute of Thailand (E.I.T. 2534) and American Concrete Institute (ACI 318-99) standards. The supplementary part contains a design aid, which is a program written in Microsoft Excel 200. The program covers the design of beams and slabs based on ACI Standard 318-99. This small supplementary program concept is to allow user to input in a user-friendly way and to provide output, which is easy to read and understand.

SOLVING TRAFFIC CONGESTION IN BANGKOK

2009-09-01T06:51:00.000-07:00

By considering historical traffic record, the main roads of inner central of Bangkok face serious traffic congestion, quantity of cars on road is more than 2,000 cars/hr, eventhough many approaches were implemented on this area. As a result, road pricing approaches were implemented on this area. As a result, road pricing approach shall be considered as another choice for traffic congestion relief, especially in developed countries. So objective of this research is to find the relationship between public attitude on acceptance road pricing system and factors influencin to their attitude.

By cosidering the quantity of traffic, pollution, financial and operation criteria, road pricing system should be implemented on inner central of Bangkok area, system area, that is area between Chaophaya River, Sathon Road, Witthayu Road, Ratchprarop Road, Ratchawithe Road, Rama VI Road and Lanluang Road. The survey was done by using questionnaire with random sampling for the people in Bangkok. Then the gathened data were analyzed by using kolmogorov-Smirnov test, Run test and Chi-square test. For the conclusion the factors influencing to their attitude are age, income, car using frequencies of entering in system area and stress from traffic congestion. From the result of the public attitude survey, most of surveyed people agreed with applying road pricing system on system area.

DOCUMENT SEGMENTATION WITH VISUAL C++

2009-08-29T23:49:00.000-07:00

Recently, Computer Information Technology was developed rapidly both hardware and software, so, it have create more document for different type of work. The document has more complexity in it. And some, has included picture to be a part of their document to make it more beautiful or user can understand easier. Now it is widely spread out for this kind of document in the information world such as textbook, magazine, etc. The complexity of the document, contain the picture and text box in the one document, make it difficult to get only picture or text box because almost of the document will pass the scanner that make the document become a bitmap picture.

Database on World Wide Web Project is arranged for sale spare parts web site. This project collects data of spare parts into database for any users through World Wide Web. The users could find spare parts by searching from their names and their manufacturers model of the cars that are compatible with these spare parts. After users confirm to buy, the invoice will be shown on web page.The main parts of this project can be divided into two parts which are Web Server and Database Server. Web server will serve web page which user’s request. Database server is the Database Management System which will manage all data. This project uses Apache-Jserv as Web Server and Oracle as Database Server. The application development will be written in Java Servlet that enable web server to search and manage data in the database.

DATA WAREHOUSE

2009-08-29T23:39:00.001-07:00

This project deals with the studying and designing of Data Warehouse, a new kind of Database, and compares with Relational Database. The studying about the multidimensional database theory and concept from a software based on multidimensionality, namely “Pilot Decision Support Suite version 5.0” and the application has been developed with Delphi version 4.0 for searching data from the Oracle database. This application can build models from any tables that a structure is multidimensional database and users can analyze the data from data warehouse with flexibility.

Making decision for investment is often concerned with prediction of data’s trend or value. To predict trend or value, we must use some techniques for analyzing data to discover patterns. Then we use that discovered patterns for prediction. Data mining using backpropagation neural network is one solution to prediction. It’s very interesting and can be adapted in many application. This project present the creation of Backpropagation neural network generator and trainer program using object-oriented programming, and experimentation aimed to find the best topology for neural network which will be used to predict the lottery.

COMPUTERIZED VOICE SYNTHESIS

2009-08-29T23:33:00.000-07:00

At present, the computer system application of speech research is the most interesting topic in technology sphere. Also Thai Computerized Voice Synthesis is one of the interesting subjects. Thai Computerized Voice Synthesis consists of three major parts: Word Segmentation in Thai Sentence, Phonetic symbols generator and Voice generator. This research presents the method of Word Segmentation. “Wordbucket Algorithm” will be implemented in order to segment the longest word compared with dictionary. Phonetics symbols generators is generated by MPT-networks which produces basic phoneme. And then phonetics symbols generated by MPT-network will be integrated into one Thai syllable.

Important information must to encrypt before sending. This research summarizes the details of variety encryption that is used to select software to be appropriate for security work.Multimedia information is favor to use very much because this information can output in the style that old style information, such as text and picture, can’t output. But this type of information has a size problem so to send information through network that you need to use streaming technology.

COMPONENT SOFTWARE DEVELOPMENT

2009-08-29T23:18:00.000-07:00

This research mainly presents the Component Software Development that based on COM (Component Object Model) technology. This technology is used to develop other technologies such as ActiveX that is technology used in Internet software. To use Com-based technology to develop software will give products good benefits from technology such as reused software that is not dependent on development tools etc. Furthermore in this research also presents a method to build Com-based software such as ActiveX Control, ActiveX Document, ActiveX Server and ActiveX Scripting. We can use all of these technologies to develop complex software.
