We study the topics of the lectures in Analysis in 19th century at Ecole Polytechnique of France through the lists of the contents of the Cours d'Analyse by Cauchy, Sturm and Jordan, respectively and also we show how they stated the definitions of functions, continuity and limits in their Cours d'Analyse. Through this, we see that in 19th century, in France, analysis included differential and integral calculus, differential equations, variations and applications of these to differential geometry, and it was far from today's mathematical analysis.

Im Gegensatz zur $gegenw\"{a}rtig\;\"{u}blichen$ rhetorischen Analyse des literarischen Textes, die $haupts\"{a}chlich$ elokutionell ist, wird hier versucht, anhand des Prozesses um des Esels Schatten von Ch. M. Wieland einen Analyseansatz aus den 4 anderen Teilgebieten der Rhetorik zu suchen. Dieser inventionelle Versuch, ist eine $Teilaktivit\"{a}t$ im Rahmen der rhetorischen Analyse und damit selbst ein Desiderat der Forschung. Als Gegenstand der Analyse ist derjenige Text am passendesten, der eine rhetorische Situation darstellt, in der Situations-Interessierte durch parteiliche Rede an den Situationsmachtigen die $\"{A}nderung$ der Situation versuchen. Dabei wird die Rede den kanonischen Regeln der Inventio unterworfen und ihre rhetorische Strategie zur Persuasion wird $folgenderma{\ss}en$ entwickelt:

Fuzzy controllers still remain ill-accepted in the control community. As a matter of fact, their design relies on a new relation between the material world and the scientists. Whereas some theoritical studies are carried out on this subject, experimentations on processes show what fuzzy techniques can bring to the control theory.

It is impossible to directly analyse stress distribution on thin bevel Gear. On this Paper, the author propose a method to analyse the stress of thin bevel gear boundary element method and develope a computer program. The propriety of this program is verified by comparing the numerical calculating results with theoretical results.

Recently Among indoor noises plumbing noise from supply and drain water pipe is being pointed out as a annoying noise following to floor impact noise, and it is increasing the rate to point the noise due to the following several reasons: water pressure, vibration by fabricated structures and direct noise propagation from upper floor through ceiling This study aims to analyse the characteristics of toilet stool plumbing noise in apartment bathroom which are generated by crossing plumbings and elbows. And it analyse the effect of noise reduction by soundproofing and insulations which are covered at crossing plumbings. And also analyse the characteristics of noise about a type of elbows, crossing plumbing and result of dB(A). At last it provide a fundamental data for the purpose of reduction of plumbing noise in apartment.

Distribution of fracture system is an important factor to analyse instability of jointed rock slope. In the most case of rock slopes, joint distribution properties are related to potential, shape, size and locality of slope failure. The purpose of this paper is to present an application of fracture characterization related to rock slope failure. Fracture data used in this study are collected by scanline survey. Two aspects of fracture characterization for rock slope are handled in this study First, In order to determine the potential and shape of slope failure, trace length of joints is considered as the weighting factor about collected orientation data. Second, Relationship between trace length and spacing is analysed to estimate failure location and size. The distribution of fracture system is directly influenced on wedge failure. It is effective to analyse the orientation of fractures by using weighting factors associated with the trace length of fractures rather than to analyse only that of fractures. It gives a conclusion that the wedge failure occurred along the peak of fracture density(or intensity) cycles.

To make the autonomous mobile robot move in the unknown space, we have to know the information of current location of the robot. So far, the location information that was obtained using Encoder always includes Dead Reckoning Error, which is accumulated continuously and gets bigger as the distance of movement increases. In this paper, we analyse the effect of the size of the two wheels of the mobile robot and the wheel track of them among the factors of Dead Reckoning Error. And after this, we compensate this Dead Reckoning Error by Kalman filter using Gyro Sensors. To accomplish this, we develop the controller to analyse the error components of Gyro Sensor and to minimize the error values. We employ the numerical approach to analyse the error components by linearizing them because each error component is nonlinear. And we compare the improved result through simulation.

A solution of magnetic fields for amorphous core transformer has been tried using homogenization technique. The technique, which is derived by applying asymptotic expansion to the standard finite element method, is helpful to analyse a joint part of amorphous core transformer microscopically. A butt-lap-step joint type of lamination method is modeled and its equivalent reluctivity is calculated to analyse various quantities of the magnetic fields. The algorithm is also applicable to other electric devices which have complicated material structure with repeated patterns.

This analysis of numerical procedure is prediction of laminar flow and heat transfer at two dimension and steady flow in asymmetric sudden expansion channel. At former study, to analyse the flows with separation, the full Navier-Stokes equation is used, but there are many difficulties to analyse, and although significant progress has been made in the development of efficient computational methods for the Navier-Stokes equations, very large computation times are still required. In case of reward-facing flow, boundary-layer equation is used instead of full Navier-Stokes equation to analyse velocity fields, and result of this numerical analysis is good agreement with the given experimental study. In this case, since the computer time required for the boundary-layer calculation is an order of magnitude less than required for the solution of the full Navier-Stokes equation, this boundary-layer model provides a good approximate solution.

This paper is relate to the result of pilot test in Asan. In order to evaluate the characteristics of behavior and deformation in Asan and to analyse the effect of soft ground treatment, preloading, two types of paper drain and pack drain were constructed in the ground. Settlement gauges, pressure meters, pressure cells and ground water gauges were monitored and also borings and piezoncone tests were performed. As a result of analyse, every vertical drained area was consolidated over 90% degree of consolidation but preloaded area was not reached to 90%.
