背理法を用いない論理体系とその証明計画
Get PDFP(論文)In a proof by reducio ad absurdum (RAA),once we put false assumptions, it is hard to distiguish true statements from others in the following part of the proof. On the other hand, all intermediate statements in a direct proof are true. This means that a direct proof has far more informations than the corresponding RAA proof. Therefore, from educational point of view, it is very fruitful to write proofs without RAA.In our former research, we introduced an efficient logical system called WNK which is free from RAA. However, ordinary proofs used in mathematics are closer to NK of Gentzen rather than WNK. In this paper, we introduce another logical system PNK which is also free from RAA, and explain the planning method of PNK proofs by means of sequents.departmental bulletin pape
A trial of the lesson improvement based on the Scout Method
Get PDFP(論文)Cooperateive learning and PBL ( project based learning or problem based learning ) attract attention because the effect of these methods is said to be high. In this paper, the author tries to consider why they are effective. Cooperative learning and PBL are based on group work. The group work was deveroped by the educational method of the Boy Scouts ( called by the Scout Method ). Therefore, it can be said that the essence of cooperative learning and PBL are understood by analyzing the Scout Method. We will consider the essence of the Scout Method. Furthemore, the author reports a trial of the lesson improvement based on the Scout Method.departmental bulletin pape
The Investigate for Growth and Fitness on College of Technology In Tokyo Metropolitan College of Industrial Technology Arakawa
Get PDFP(論文)身体測定の結果から,全体的には身長・体重ともに全国平均とほとんど変わらないが,肥満および高度・重度肥満にある学生が全体の14%ということで自ら健康管理ができるように今後指導する必要がある.新体力テストの結果から,1年生から3年生まですべての学年において,筋力・筋持久力,心肺持久力,柔軟性が全国の高校生に比べると顕著に低いということが判明した.敏捷性,瞬発力については同等の能力であることがわかった.今後保健体育の授業において種目の選定や授業内容の改善の必要性が多いにあると考えられる.また,運動の日常化,体力や健康に関する意識を高めその自己管理能力を高める指導が不可欠であるといえる.departmental bulletin pape
Expansion of Education Using 3D-CAD in the Design Program
Get PDFP(論文)"The most important purpose of engineering is to design; however, one important upstream task is styling design. While sketches, clay models and other analog models are said to be the most common media for styling design, it is becoming more common for manufacturers to use 3-D CAD data at this stage of design for their own products. For this reason, our department has begun to apply 3-D CAD in styling design and is looking into further digitization of the design process. Two prominent aspects of this are surface CAD and reverse engineering.Digitization of models, in either a 3-D surface model or during reverse engineering, will make the design available to users throughout the engineering process, and will enable users to shorten the time between development and commercialization. In addition, digitization provides more accurate data, enabling manufacturers to eliminate internal errors when it is time to make a model change.This report details the design curriculum of our department, which takes advantage of up-to-date equipment in the field of mechanical design."departmental bulletin pape
集中開講による物作り授業の実践
Get PDFP(論文)We performed a intensive course in an elective subject by the workshop seminar of theproduction for the first time during summer vacation. We open a course in 3 themes every year so farfor four years and each theme piles up improvement every year. We let a student choose 1 themeamong a velocity of the wind vehicle, the large size paper glider and the stirling engine now. Thosethemes have personal production or group production, and there is a thing to design originally orproduction it according to a drawing again, and there is variety. Our students to choose surpass 60%of a class. They learn behaviorally and achieve enough result.departmental bulletin pape
Acquisition of Two-clause Structures by Japanese ESL Learners: What Factors Make Some Structures More Difficult to Acquire than Others?
Get PDFP(論文)This study discusses the acquisition of two different groups of two-clause structures by Japanese ESL learners; group A includes sentences with relative pronoun and relative adverb clauses, and group B includes compound and complex sentence combination patterns. The results of the experiment in this study suggest that there could be general principles in the cognitive aspect over the different syntactic categories.departmental bulletin pape
DYNAMIC CHARACTERISTICS OF WELDED STRUCTURE(EFFECT OF WELDING ON FIRST AND SECOND VIBRATION MODE)
Get PDFP(論文)Welding is widely used for construction of many structures. Effect of welding on dynamic characteristics and reliability has not been clear. Inthis paper, effect of welding on the damping ratio and the natural frequency is examined by experiment. By using many specimens of same size, thedamping ratio and the natural frequency are estimated. It is concluded that the damping ratio of welded specimen is larger than that of base metal.The natural frequency of welded specimen is almost same as that of base metal. Next, effect of welding on reliability of structure is examined forwhite noise excitation. For first excursion problem, reliability of welded specimen is higher than that of base metal.departmental bulletin pape
Basic examination for CMOS pseudo random pulse generators though the logic circuit simulation and trial fabrication
Get PDFP(論文)Pseudo-random bit sequence (PRBS) generators which can simulate the generation of the actual information signal, are installed in the transmitter side, as well as bit error rate detectors are installed in the receiver side to evaluate transmission properties of the optical communication systems. Although very expensive, these measuring instruments have been used compound semiconductor devices as GaAsMESFETs to get high-speed operation.This time, the examination circuits of the PRBS generator are applied to economic CMOSFETs which have low-power consumption and expected to have high-speed operation by shortening channel length of the CMOSFETs.Basic operations of the PRBS generators employed CMOSFETs are confirmed through logical circuit simulations and measurements of the trial manufactured circuits in this study.departmental bulletin pape
The Novel""The Reader"" of Bernhard Schlink
Get PDFP(論文)Why does Hanna commit a suicide? This is our question. In the prison Hanna learnsletters and comes to be able to read books, with the aid of the cassette tapes sent byMichael. She begins to read literature on concentration camp. She overcomes herilliteracy and moral illiteracy. She has no hope in the world outside of the prison. Theprison is, as it were, a convent to Hanna. Michael is a bridge from a convent to the world.Hanna was disappointed with the rejecting attitude of Michael. This is a trigger to Hanna'ssuicide. The main reason is to have recognized the guilt of her past.departmental bulletin pape
Mathematics Course in Colleges of Technology for Industrial High School Students
Get PDFP(論文)In Tokyo Metropolitan College of Industrial Technology, we accept industrial high school graduates as the fourth grader after an entrance exam. In spite of their desire, they cannot help themselves out of having a hard time because of discontinuity between industrial high school mathematics and technical college mathematics. We have to intend a mathematics course as an appropriate help for them and develop appropriate teaching materials.departmental bulletin pape
