Reading Haruki Murakami's "The Second Bakery Attack"
Get PDFP(論文)This paper is based on a lecture "To know Japan," a part of the immersion program carried out on the 11th of September, 2012. This lecture was given to twenty students in Ngee AnnPolytechnic, Singapore, with the title ""Think about modern Japan through reading `The Second Bakery Attack' by Haruki Murakami."" I revisedthe points which could not be discussed within the time frameto a degree and deleteda part of the materials. The interpretation of this work is a result of discussions between Takano and Unagami, and both of them are responsible for the wording of thispaper. Unagami is in charge of translating the contents into English.departmental bulletin pape
Basic Examination for CMOS Bit Error Rate Detection Circuits though the Logical Circuit Simulations
Get PDFP(論文)Bit error rate detection (ED) circuits which are installed in the receiver side, are employed to evaluate transmissionproperties of the optical communication systems. Although very expensive, these measuring circuits have been usedcompound semiconductor devices as GaAsMESFETs to get high-speed operation. This time, the examination circuitsof the ED circuits are applied to economic CMOSFETs, which have lower power consumption and expected to havehigh-speed operation by shortening those channel length. The basic functions of the ED circuits which includesynchronization, error counting, and monitoring control of out-synchronization are investigated through the logicalcircuit simulations on PSPICE. The operations of the ED circuits employed CMOSFETs are confirmed through thelogical circuit simulations.departmental bulletin pape
Study on the Physical Growth and Development at College of Industrial Technology
Get PDFP(論文)Globalization has made progress in our modern society over recent years. To adapt the globalization, developing richness of spirit and a healthy body are needed in physical education. However now there are many problems that children's physical strength weak and their concerns and desires toward exercise are decreasing. To solve such problems, our college has introduced the new test of physical fitness from 2000.At this report, we compared the new test of physical fitness results of our college students with the national men's averages to know physiques and motor abilities on the basis of 2011 the new test of physical fitness results of our students.As a result, physiques of our college students were more than its national men's average. But in terms of motor abilities, the results were less than its national men's average in particular the muscular endurance, the whole body endurance and the speeding (running ability). It can be said that supports for our school students in the field of promoting their health are one of the most important tasks.departmental bulletin pape
A Study on the regional characteristic of the shipping at the Small Port Town,Takuno-ura in the Edo period
Get PDFP(論文)本稿では,石見銀山御料の小規模な港町,宅野浦における廻船商売がどのように展開したかについて,ほぼ18 世紀を通じて廻船商売を営んだ商家,増屋の史料を用いて具体的に検討した.宅野浦は,江戸初期の石見銀山盛期に,そこで用いられる鉄道具の原料となる鉄の集荷と関わって形成されたとみられる.江戸中期における増屋の廻船商売は,出雲西部や石見銀山御料の日本海沿岸の港町を介して鉄を集荷し,大坂方面へ廻送することを中心としていた.これは,この港町が,鉄の集散との関連で発展したことをうかがわせるものであった.また,石見銀山御料の鉄の生産と流通においては,鉄生産地と港町を結ぶ者,御料内の各港町と大坂など遠隔地の市場とを結ぶ者の分業と連携が重要な役割を果たしていたことが明らかとなった.departmental bulletin pape
Monitoring of Ground Deformation in South-East Part of Metro Manila,Philippines by Ground Survey
Get PDFBuildings and pavements are damaged by vertical ground displacement along the creeping segment of the Marikina Valley fault system (MVFS) on the south-east part of Metro Manila, Philippines. To clarify fault creep trigger, ground deformation is monitored through repeated leveling surveys. And short term link between fault displacement and rainfall is also monitored through a continuous creep measurement device installed across one of the sites used for leveling survey. From repeated leveling surveys, the average slip rate since September 1999 to January 2010 ranges from 1.07cm/y to 2.16cm/y. Creep acceleration is observed in some leveling survey sites. Continuous creep measurement obtained an average slip rate of 0.01mm/day (3.65mm/y) until January 2009.However fault creep at NPC B appears to have stopped even with the coming of the rainy season in May 2009.departmental bulletin pape
Research on a teaching method of paragraph making
Get PDFP(論文)The aim of this paper is to investigate the effects of a teaching method of writing with a focus on two kinds of feedback; written corrections and direct discussion with each student. With the number of errors (articles, prepositions and verbs)as the criteria, I looked into the changes of students'writing abilities. As a result, some improvements could be acknowledged,and what kind of feedback was more effective differed depending on whether the errors were articles, prepositions or verbs. I would like to show the effects at the end of this paper.departmental bulletin pape
Planning of Proof by Heuristic Tableau
Get PDFP(論文)In a heuristic process of proof in mathematics, we try not only forward derivationsfrom the assumptions such as `from A, we get B' but also backward derivations from theconclusion such as `in order to get C, we need D'. Thus, we have to discover all the statementswhich connect assumptions with the conclusion, to complete the planning of the proof. Wedefine `heuristic tableau' as a tableau which consists of those statements aranged in the order of discovery with symbols which express the logical relations of those statements. We suggesta planning method of proofs by using heuristic tableaus. For a concrete explanation, we use the first order NK system of Gentzen to explain our method. Our method gives an algorithmto prove arbitrary tautologies of the first order NK system, and is also valid for practical mathematics which is not necessarily formalized in symbolic logic.departmental bulletin pape

圧接試験片における接合部電気抵抗の基礎的測定
Get PDFP(論文)A rated current of a lithium ion battery bank for an electric vehicle (EV) is about 50 to 70A, andthenaninstantcurrent of the battery exceeds 200A. When the current flows from the battery bank to a driving motor, the cells composing the battery have a chemical reaction heat. And then, the heat is conducted to the current-collection-tabs connected with the battery. It is considered that the sheet metal is connected with the tab as one of the solutions in order to maintain the ability of the power supply. Magnetic pulse welding is effective for lap-joining similar and dissimilar sheet metals such as Al/Al, Cu/Cu and Cu/Al. In this study, a voltage drop of the juncture of the sheets obtained by this welding method was measured 1000 times automatically by botha crossed rod method and a four-wire terminal method, and an electric joining resistance of the juncture was estimated by an average value of the voltage drop. The joining resistances, Al/Al and Cu/Cu, were less than 5 μΩ both. Therefore, the joule exothermic reaction of the juncture by the passage of the large current is small, and the absorption of the heat which arises in the battery can be expected.departmental bulletin pape
A Survey on the Instruction of Relative Clauses in the Revised High School Textbooks
Get PDFP(論文)This paper reports the results of a survey on the teaching approaches in the revised MEXT-censored Englishtextbooks for junior and senior high schools focusing on whether there are any hints that can contribute to coping with thedifficult relative clause types. The results suggest that the types of relative clauses that are difficult for learners will remaindifficult unless each instructor (1) keeps a balance among the sentences to present to the learners, and (2) gives them someadditional exercises to help them understand the relative clause as a module in the main sentence which can be used both in thesubject and object positions.departmental bulletin pape
