Manufacturing trends are gradually changing from mass production and mass consumption to “production of diverse products in small quantities”. For this reason, design is recognized as an important element with which a customer judges value. In order to employ the designer’s sensitivity and realize high quality designs, CAD systems which can carry out analysis evaluation of design properties quantitatively, and improve design based on the results is required. In the initial stage of designing, designers embody image form by repeating a sketch. In this process, if the form image of a sketch curve can be evaluated quantitatively and the design form image can be controlled based on the evaluation parameters, this will provide effective design support. In this research, we proposed parameters by which the image of sketch form can be evaluated quantitatively, and investigate the tendencies of various curves and curved surface form. We also developed a system which reconstructs design form using the proposed evaluation parameters.

Narratives of flexible specialization as an alternative to mass production are largely absent from the industrial history of twentieth-century Britain. In this article, I challenge the notion that we should relegate small firms and industrial districts to a marginal place in the historiography of this period. Drawing from a range of sources, I explore the history of Birmingham's jewelry makers to show how they adapted the traditional productive system of the district to respond in a dynamic way to the challenges of rapid product market differentiation. As jewelry increasingly became a commodity for mass consumption, the firms in the Birmingham district used a combination of specialty and mass production as a strategy to both satisfy and create demand.

Abstract Reaming plays a crucial role in production to meet the high quality requirements of precision bore machining. It is either directly responsible for the final component quality or influences subsequent processes such as honing. The narrow tolerances are usually monitored by measuring random samples in mass production due to cost efficiency. Having a closer look at an exemplary process chain for the production of hydraulic valves shows the possibility to adapt the honing parameters which reduces processing time and costs. However, the bore straightness after the reaming process has to be known. In this paper an approach is presented which allows to record the bore straightness within the productive time. For this purpose, a sensory reaming system is developed. It can be used without additional components in the machine tool and thus integrated into existing machining processes. Cutting tests show that the system is able to measure the bore straightness as good as sensing probes used in machine tools.

In this study, composition for bottom ash and fly ash of MSWI was analyzed and zeolite was synthesized in order to expand its recycling on high quality and mass consumption. Analysis of ash its characteristics was performed by XRF, XRD, SEM, EDX, TG/DTA. Bottom/fly ash was fired for elimination of unburned carbon at 750°C/12 hr, crushed and synthesized to zeolite in 1, 2, 3, 4, 5 M NaOH solutions under 105°C/24hr by hydrothermal method. Calcite and calcium-silicate compound was mainly contained in bottom ash and CaCl2∙4H2O, Ca (OH)2, NaCl, and calcite and KCl in fly ash. Especially amount of Cl was much contained in fly ash due to Korean food waste characteristics. Bottom ash could synthesize Zeolites in form of sodalite under 3~4 M NaOH and fly ash could synthesize Zeolite A under 1~2 M NaOH. In addition, zeolite synthesized with bottom ash had higher specific surface area and zeolite from fly ash had higher CEC value. Accordingly, ash from MSWI could be recycled for further valuable uses such as non-point pollutant control and/or soil amendment.

Initial Stage

Descriptive statistics is the initial stage of analysis used to describe and summarize data. The availability of a large amount of data and very efficient computational methods strengthened this area of the statistic. In this chapter, we introduce the main concepts related to descriptive analysis. These will provide a vast quantity of knowledge to perform a high-quality descriptive analysis.
