Research on the Influence of Fabric Properties on Men’s Suits Shape

The shape is an important factor to form the garment style and manifest its beauty. It is affected not only by the style and design but also by the fabric properties. A systematic experiment was carried out by selecting twenty commonly used suit fabrics and making use of KES fabrics instrument. The main indexes were drawn by Principal Components Analysis (PCA), which mainly influenced the men’s suits shape. The obtained results will surely help to make the selection of fabric easier, provide the reference to the men’s suit design and manufacture, and thus produce high-quality men’s suits.

Aspect Mining Based on Object-Oriented Systems’ Dynamic Behavior Models

Aspect mining is a reverse engineering process that aims at finding crosscutting concerns in existing systems. This paper describes an aspect mining approach making use of the results of reverse engineering, statechart diagram, to aid in the understanding of an object-oriented software system’s behaviors. An aspect based on the recovered statechart diagram is defined as a set of states and an event. These states will transit to the same state after they send the event. Finally, systematic experiment is conducted in the paper in order to verify the correctness and validity of this approach.

Experiment of Flow-Induced Vibration Phenomenon in Undergraduate Student Experimental Class

The fluid engineering experiment class for undergraduate students in Nagaoka University of Technology is explained. Students learn the fundamental theory of the flow-induced vibration by teacher’s lecture and the video program in class room and move to the experiment room. They play with some simple device that is designed to cause the phenomenon of the flow-induced vibration. It is not difficult to cause the flow-induced vibration phenomenon on the devices but a few training and knacks are necessary. These devices were made by us for this experiment. Controlling the oscillation of these devices is interesting and it excites students so that we call them toys. Students learn the influence of various factors that cause the occurrence of the resonance and the fluttering through this experience. After this experience, they start more accurate and systematic experiment using the wind tunnel equipment. They write the report, and discuss their experiment result. We explain the details of these student experiment class and demonstrate the toys for the flow-induced vibration phenomenon.

Uncertainty Analysis of Three-Dimensional Coordinate Measuring Machines

On the basis of the condition that the distances between planes be measured in accordance with the ISO guide ""Uncertainty of Measurement"", the uncertainty of measurement of a CMM in the orthogonal coordinate system has been obtained by carrying out a systematic experiment. So the expanded uncertainty is given as 4.4μm.
