ABSTRACT :
The objective of this research is to develop utility programs for conversion, compression, and encryption of CU-Writer for Windows 78 document files. The programs can convert the structures of text, CU Writer version 1.52, version 1.6, and CU-Writer for Windows 77 files to the CU-Writer for 78 file structure by maintaining the character attribute, picture, and table appearances. Document files can be compressed in size when saving the file by using the LZW compression technique and can be decompressed to the original file when openning the file. In addition, the programs can encrypt content in document files for security purpose using the IDEA encryption technique by allowing only the user who has the right key to decrypt the files to the original content. These utility programs were developed as a dynamic link library for CU-Writer for Windows 78. Experimental results showed that the converion approximately increases the file sizes from 100 percent to 300 percent, the compression reduces the file sizes to be 10 percent to 60 percent of the original size, and there is no effect on file size for the encryption. Moreover, the results showed that better compression efficiency can be achieved by perfoming the compression, then the encryption before saving the compressed-encrypted files.

ABSTRACT :
The objective of this thesis is to convert raster data of graphic primitives such as lines, arcs and filled polygons to vector data. Raster data used in the conversion is in PCX or TIFF file format. The result which is the vector data is stored in DXF file format. Raster-to-vector conversion composes of many steps which are:- reading raster data from file, finding the skeleton, filled polygon separation, finding the vertices of filled polygons, finding the coordinates and width of lines and arcs, and finally, saving vector data in DXF file format. In addition, this thesis provides an editor which can be used to edit the output of the raster-to-vector conversion program. The results show that converting raster to vector can be done successfully with small errors. The errors found in this thesis are as follows: some errors occur for the vertice of lines and filled polygons, the center points and the radius of arcs, and the width of arcs and lines; a small arc may be converted to a line; a line that has a slope between O to 1 and does not have any connected object is converted to a few lines. Types of images that give the best results are simple geometry shapes and electronic symbols, respectively, while contour maps gives fair results.

ABSTRACT :
This research has the objective to solve restrictions of displaying Thai characters on UNIX terminals. In English, all characters are displayed on the same level, this characteristic is suitable for storing data in string data type. But in Thai, characters are displayed on three different levels. Storing data in string data type does not allow displaying 80-column Thai characters in one line of display screen. Also, compensation for vowel and tonal characters prevents the use of some columns on the line. This research develops 2-dimensional curses library which stores data in Thai characteristic. Furthermore, a terminal emulation program is developed to support the 2-dimensional curses library.

KEYWORDS : PHIGS % LIBRARY % 3-D MODEL % DESIGN TOOLS
ABSTRACT :
The objective of this research is to study PHIGS in the way of PHIGS's function and how to use it for developing the computer graphics applications. PHIGS's implementation which is used in this research is SunPHIGS 2.0. The study of using PHIGS for developing applications is done by developing an application program as a case study, which is 3-D Modeling Tools. The GUI of 3-D Model Design Tools were developed by using XVIEW Toolkit and SunPHIGS 2.0 for managing graphical output and graphical data. The program starts from creating 2D shape to define 3D geometry of an object. The model can be constructed by composing objects or other models whose relationships were defined in hierarchical structures. The goal of this program is to display a rendered scene which is composed of 3-D models. The functions of this program were designed to work in a similar way as the PHIGS's. The result from this research indicates that the advantages of using PHIGS are that it is easy to use and device-independent. The disadvantage is the inefficiency of the functions for managing central structure store. The disadvantage of SunPHIGS 2.0 are the complex data structures, low performance on X window system and the inefficiency of logical input devices. Developing applications by using X Tool workstation is easy but the performance of the applications are not good, while developing applications by using X Drawable workstation is complicated but the performance is better. 3-D Model Design Tools works on SPARCStation IPX which has at least 32 MB of memory and use UNIX release 4.1.2 for its operating system. The X Window System which is used for this program is OpenWindows 3.0.

Parsing ILL-Formed Thai Sentences with The LR Parser

KEYWORDS : GLR PARSER % GLR-IGLR % GSS BACKTRACKING % ILL-FORM % PARSER
ABSTRACT :
This research proposes three strategies to process ill-formed input sentences by means of an extended GLR parser. The first strategy edits error only at the detected position while the other strategies, called GLR-Inverted GLR (GLR-IGLR) parsing and Graph-Structured Stack (GSS) backtracking parsing, not only handle the erroneous element at the detected position but also edit other overlooked positions. In general, editing error only at the detected position is not enough because it is possible that the detected element may not be the real erroneous element. The second strategy, GLR-IGLR parsing, can cover the errors more than the first strategy; however, some defective points are still overlooked because it has no process for handling the parsed errors before the detected point. The last strategy, GSS backtracking parsing is more effective than others but it also needs more complex implementation and spends longer processing time. However, by limiting the scope of error editing appropriately, this method will be an effective parsing and uses less time. Consequently, this method is the suitable parsing for handling ill-formed input in a real work. Aside from the ill-formed input parsing module, we include the method for collecting the statistics of deviated data which can guide us to adapt the current grammar to attain better performance.

ABSTRACT :
The objective of this research is to develop a software package on Windows to assist users to manipulate colors in images. Users can select -0 image regions before adjusting their colors by using either auto mode or 0 manual mode. This software package also gives users a tool to make boundary changes afterwards. The colors of the selected regions can be changed in two ways: the first one is changing to a new solid color and the other is changing to new colors which maintain the original continuing color tone. The way to change color in the selected regions can be chosen depending upon many factors which are the RGB differences, the hue differences and the hue, saturation, intensity differences. This research results in a software package called the Color Management Tools which fulfilled the objective. Moreover, this Color Management Tools provide users many fundamental tools to play with images. These tools consist of adjusting brightness and contrast, hue, saturation, intensity, red, green, and blue; splitting a color image to grayscale images; of red, green,and blue components; splitting a color image to grayscale images of cyan, magenta, yellow and black components; flipping images; inverting colors and computing values of two images by adding, subtracting, E multiplying, dividing, finding minimum value, finding maximum value and finding average value.

ABSTRACT :
The objective of this thesis is to develop a visual control class for binary heap data structure. Not only the usage of this control is the same as the standard one but also the aperation provides output and manages the heap data structure which is a complete binary tree in a contiguous storage. The control comprises of properties, events, methods, and functions which are both standard and customized exclusively for this control. Developing of the control is similar in many respects of writing a standard Windows application as to receive, send, and response to the messages. The file from developing control is a .VBX extension which is actually a Windows dynamic-link library (DLL), designing to interact with Visual Basic in specific ways. The control can be used in Visual Basic to construct a binary heap data structure which operates as general data structure, for example: insertion, deletion, sorting, and accessing the data. Moreover, the control is able to demonstate steps in heapified data structure which benefit to education. This control is developed with Microsoft C/C++ Compiler version 7.0 and intends to use for Visual Basic version 3.0 under Microsoft Windows version 3.1 on personal computer.

ABSTRACT :
This study investigates the application of computer playing Thai chess. It consists of three parts; one, study and comparison of two selective-deepening search algorithms: alpha-beta (AB) and conspiracy numbers (CN)i two, development of a CN Thai chess program; and three, evaluation of CN iand AB (which has been previously developed) Thai chess programs. Findings of the third part were based on five sets of experiments, SE-1 to SE-5, each of 10 games. The algorithm that checkmated or had a higher material value before both algorithms generated repeating moves was considered to have won the game. Results of each set were summarized as number of CN wins to number of AB wins (CN:AB); games not ending with a checkmate or a difference in material values were not included. In SE-1, parameters were selected to allow both algorithms to generate approximately similar node-numbers per move. CN:AB result of 6:1 was obtained. In SE-2, CN branching factor was increased to favor CN with CN:AB result of 8:0. In SE-3, as compared to SE-1, AB depth was increased to make movetimes of both algorithms more equal. This favored AB, and CN:AB result of 4:5 was obtained. In SE-4, as compared to SE3, CN threshold and branching factor were increased to allow both algorithms to generate more than 1,000 nodes per move. This favored CN, and CN:AB result of 7:3 was obtained. In SE5, as compared to SE-3, AB depth was increased to make movetimes of both algorithms more equal. Although this favored AB, CN:AB result of 3:5 showed only a slight improvement for AB. AB lacks search depth and requires less time to generate moves. If time is not a constraint, and if both algorithms are allowed to generate similar node-numbers, the results indicate that CN would outperform AB for Thai chess programs. Further work is needed to improve search speed and memory use of the CN Thai chess program developed in this study.

ABSTRACT :
Connecting microcomputers as a network is usually done in order to exchange information and to share computer resources. This thesis presents a design and development of a microcomputer network using standard RS-232C serial ports as communication channels. This is done by connecting from client microcomputers using twisted-pair wires to a server computer in a star topology. Each client and also the server have communication software designed to comply with the OSI standard : using socket concept in the physical layer, adapting the XMODEM-like protocol in the datalink layer, controlling security in the session layer using user name and password, and implementing network drive redirector and print spooler in the application layer. The software was developed using both Assembly and C languages and can be run on 386 (or higher) computer running MS-DOS. Experimental results showed that the effective data transfer rate during disk read and write are comparable to those of similar software, but with more number of clients and print spooling capability.

KEYWORDS : MARK RECOGNITION
ABSTRACT :
The objective of this research is to study and to develop a prototype of a scanner-base multiple-choice recogrution system. The software prototype of a scanner-base multiple-choice recognition system was designed and developed to recognize 4 types of marks: cross sign, check sign, circle sign, and darkened-circle sign. The recognition used in this research consists of 2 approaches. Firstly, the system checks whether the sign pocesses the right characteristic. If it passes the test, then the system must check whether it pocesses the wrong characteristic to confirm the recognition result. The recognition technique in this research is statistic recognition whose value are gained by learning from the sign- features. The statistic values are the sign' s area-to-perimeter ratio, and the error distance of the signs and their mathematical models. In this research, 900 cross signs, 167 check signs, 850 circle signs and 225 darkened-circle signs were tested. The recognition rates were 97.44 percent, 89.22 percent, 93.29 percent and 99.11 percent respectively. Hence, the system recognition rate is 95.97 percent.

ABSTRACT :
This objective of this thesis, the Development of Distributed Files on the DECnet Network (DDFDN), was to develop the file distribution protocol for computer systems with centralized processing used in many business organizations. The development was intended to keep the existing application programs unchanged, to make any change transparent to the users, and to increase the ability of the systems to handle more data and users. The DDFDN was mainly developed for implementation on the Ethernet-based computer network using DECnet protocol and was tested with Management Information System for Cellular Services computer network at The Communications Authority of Thailand (CAT). This thesis employs the structure analysis and design as the analysis tool to distribute files through out the network. The DECnet protocol was used to access files remotely. The test program to measure response-time and load-capacity was developed by using COBOL program and parameter. The use of system processing time and power before and after using DDFDN in the system was recorded by utility program of VMS operating system. By testing DDFDN with the small prototype DECnet computer network, the testing result shows that after deploying DDFDN, the response time was 145 percent faster and the load-capacity (system ability) was improved about 80 percent when compared to the original network. Then, the DDFDN was ported to test in the CAT's Management Information System for Cellular Services computer network. The testing result was still the same, and also indicates that the computer network has more resource available and the users get no effect.

KEYWORDS : REQUIREMENTS PLANNING % CAPACITY
ABSTRACT :
Production system consists of four main factors: inventory control system, production planning system, material requirements planning system, and capacity requirements planning system. It was found that the third factor is always considered as the most important factor. Because manufacturers do not want to face with the problems of raw material shortage. Most manufacturers ignore their existing production capacity, this leads to the waste of both labor force and time. However, if the capacity requirements planning is planned in accordance with the material requirements planning, the efficiency of the production system should increase because the capacity requirements planning will evaluate the required production capacity within the production system. Data from capacity plan will assist in the adjustment of existing production capacity. The design of capacity requirements planning system in this thesis comprises two parts: the rough-cut capacity planning which calculates the production capacity required from the master production plan; and the capacity requirements planning which calculates the production capacity required from material requirements plan. The system design starts from analyzing the current production system in order to get both the data flow diagram and the document flow diagram, together with the problems of current production system. After that, the production stage of the new system was designed, followed by the development of the program for capacity requirements planning system. It is emphasized that this program should be easy to use, provide correct data, and quick calculation for production capacity plan. Data from SIGMA PAINTS (THAILAND) Co.,Ltd. is used a case study. The result shows that the developed capacity requirements planning system has data integrity, reduced data redundancy and time comparing to the existing production.

ABSTRACT :
This thesis presents the design and development of a computer-aided seat assignment for state banquet according to ranking, protocol, and seating regulations. Three patterns of tables are considered : the U,I, and E-shaped. The system conveniently and quickly assists the assignment process by minimizing the number of regulation violations. The system consists of four modules : data preparation, ranking process, seat assignment, and assignment printing. Each guest is ranked according to his or her career position, order of decoration, nationality and sex. Then for each seat considered in priority, the highest unseated guest is selected under the following three constraints : women and men are seated alternatively, Thais and foreigners are seated alternatively, and no couples are seated next to or facing each other. Since the number of men, women, Thais, and foreigners are uneven, the system first selects which group of guests to be seated next by sex and nationality in order to uniformly distribute the number of women, men, Thais, and foreigners,then selects the guest with highest rank in that group to be seated next. By using three state banquets as test cases, the system out performed the manual system by 26.68 percent (smaller number of regulation violations) and took only 18 seconds for a seat assignment.

ABSTRACT :
The objective of this thesis is to develop a drawing program which is a part of the CU-WRITER for Windows word processor system. The object oriented programing concept, treating each graphics object independently, is used in this program to simplify the creating, modifying and passing the graphic object to CU-WRITER for Windows. This program is developed to run under Microsoft Windows environment. In this thesis, graphic object formats, consisting of lines, arcs, circles, ellipses, rectangles, polygons and texts, are studied to determine the object properties such as size, position, line color, line width, line style and background color. Therefore the properties of each object can be set and modified individually. Techniques in computer graphic and Microsoft Windows program development are studied and applied as well. The development of this drawing program covers the design of user interface, data structures and algorithms using Microsoft Visual Basic for Windows as a key development tool. The picture created by this program can be used with the CU-WRITER for Windows and other Microsoft Window applications successfully both on screen and printer.

ABSTRACT :
This work studies the learning method of a robot arm to solve a specified problem from its experience using genetic programming. A vision system with a video camera guides the robot arm to reach the target while avoiding obstacles. The vision system records the state of the environment, i.e., the positions of the robot arm, the obstacles and the target to be used in the simulated runs during the genetic programming process. The learning process in genetic programming employs an evolution process to synthesise robot programs which are suitable to solve the specified problem. The resulting robot programs can control the robot arm in the real world. The result of the experiment shows that, under a simple| environment, the robot arm learns quickly and learns more slowly in a more complex environment. The result from the run in the real world shows that 83 percent of the synthetic robot programs work well. The failures are caused by the discrepancies between the simulation and the real world, and the uncertainty inherited in the operations of the equipment. This work illustrates that the genetic programming method can solve the robot motion planning problem with good efficiency; and the robot arm learns to reach the target using the guidance from the vision system.
