In this paper, we present the FlappyBird Competition System (FCS) implementation, a competition-based automated assessment system used in an entry-level artificial intelligence (AI) course at a university. The proposed system provides an evaluation method suitable for AI courses while taking advantage of automated assessment methods. Students are to design a neural network structure, train the weights, and tune hyperparameters using the given reinforcement learning code to improve the overall performance of game AI. Students participate using the resulting trained model during the competition, and the system automatically calculates the final score based on the ranking. The user evaluation conducted after the semester ends shows that our competition-based automated assessment system promotes active participation and inspires students to be interested and motivated to learn AI. Using FCS, the instructor significantly reduces the amount of time required for assessment.

A sub-structure is uplift if the floating greater than dead load of a structure. When such occasion arise, a structure sustain damage. In general, the measures for floating prevention of structure are a permanent anchor method and a drainage method. The primary construction cost of a permanent anchor method is heavy. And a drainage method is needed maintenance management long term. At this point, the measures for floating prevention of a notion being requires the other days. Therefore, at this study a simple construction and a economic vertical drainage system was developed. The findings be used in the in-situ and gave careful consideration to an application. The result of examination, this system considering a characteristic of coefficient of permeability for the ground controls occurrence of floating despite the water level rise of the ground, which a period of construction get shorter compared with other methods, which understood that measures satisfactory in the financial aspect. Especially, A structure occurring effects of flatting under the course of construction made use of it. As the result of the effect of it was confirmed by construction.

General Physics CAI Program was developed for university science and engineering student. The program was restricted in the field of mechanics and was mainly aimed for individual tutorial. This project was supported by Government. Department of Education, physics attending their general physics classes in university. The program was written in BASIC and constructed by frame, 4 professors and 6 graduate students were involved in the project. Summary of this study is as follows. 1. The theory of CAI was illuminated from a new point of view to enhance usefullness of CAI. Also the structure of frame type CAI was studied. 2. The program was developed as follows 1) The program consisted of main program, pretest routine, tutorial routine, final test routine, and several other routines for program control. Whole program was written in BASIC. 2) 20 problems for pretest, 90 problems and subsequent hints and solutions for tutorial, 20 problems for final test were developed. 3) According to student's pretest result, tutorial course was routed through several different courses which contain different number of problems 4) The expected rate of achievment for final test was set to 75%. 5) Data of students response to problems including number of tries and time used were recorded for the purpose of achievment analisys 3. 22 students went through whole course and the results were as follows. 1) Pretest marks were widly distributed from 20 points to 100. It means that achievement of high school physics course were not enough. 2) Throughout tutorial course, students who had got higher mark in pretest answered correctly in the first trial at a higher rate of 78 %. Overall rate of correct answer in the second trial was distributed appropriatly. 3) Average mark of final test was 78.8 points, rather a higher rate of achievement than expected. This means that the program was constructed well.

The corridors to the north and south of the $Takl{\bar{a}}m{\bar{a}}k{\bar{a}}n$ (塔克拉瑪干 Ta-ke-la-ma-gan) Desert are the most important regions for cultural confluence on the Silk Road, where caravans made it to the Chinese capital or the Korean Peninsula by the northern road, through the city of Turfan, or the southern path of Khutan. Being an important part of the Silk Road in the course of history, this region was heavily influenced by the cultures of various nations and ethnic communities whose merchants utilized the road to advance their business. The region's language, writing system and literary structure were also affected, so much so that in the course of its tumultuous history, many words, phrases and terms belonging to neighboring cultures found their way into the region, leaving their mark on its linguistic structure. Of the cultural exchanges that took place between the peoples of the region, conspicuous traces can be seen in the architecture, music, literature, texts, and inscriptions. Located in the Turfan region, the minaret of Su Gong (蘇公 Su Gong ) is host to an inscription which bears many signs of such exchanges. As so far no independent research has been conducted to identify the cultural, literary and structural features conveyed in this inscription, the present paper is an attempt to study the inscription in terms of the script, language and syntax in order to unravel the effects of cultures prevalent on the Silk Road on this particular inscription. This study mainly aims to investigate the linguistic structure of the inscription and the impact of the Persian language on Silk Road culture. In fact, we approach the inscription as a symbol of cultural exchange on the Silk Road and will focus on the tradition of Persian inscription-making which affected the Turfan inscription.

In the course of missile system design, jet plume impingement is encountered in designing airframe as well as launchers, requiring careful investigation of its effect on the system. In the present paper, recent works on such topic are presented to demonstrate usefulness of CFD results in helping design the hardware. The jet impinging flow structure exhibits such complex nature as shock shell, plate shock and Mach disk depending on the flow parameters. The main parameters are the ratio of the jet pressure to the ambient pressure and the distance between the nozzle and the wall. In the current application, the nozzle contour and the pressure ratio are held fixed, but the jet impinging distance is varied to illuminate the characteristics of the jet plume with the distance. The same methodology is then applied to a complex vertical launcher system (VLS), capturing its flow structure and major design parameter. These applications involving jets are thus hoped to demonstrate the usefulness and value of CFD in designing a complex structure in the real engineering environment.

This paper considers a sliding mode controller for a depth and course control of a class of submersible Vehicles. Since the vehicle used here shows complex dynamic characteristics sensitive to speed variation and buoyancy, robustness in control of vertical and horizontal plane motions of the vehicle is achieved by using the sliding mode controller of which a structure varies according to a pre-designed principle, so called the variable structure control. To compare this controller with another in robustness, PID controller for the same model of vehicle is designed. From various simulations for two controllers, it is shown that the sliding mode controller is the more robust anainst to modeling errors and disturbances.

The one of important requisites for fabricating molecular electronic device is the single crystal direction of bottom substrate nowadays. [1,2]. We obtain the optimum SAM result when the Au crystal is <111> structure for Self-Assembled molecular. To get the <111> crystal Au, we generally repeat heating and cooling course after evaporating Au [3]. However, we can fabricate <111> crystal Av thin film except post treatment because we simultaneously evaporate and anneal using Effusion Cell. In this paper, we study on thin film growth of <111> crystal Au as bottom electrode which is essential for Self-Assembled molecular by Effusion Cell and analyze crystal structure, thickness, surface conductivity and so on as each process condition.
