There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

The primary objective of this study is to predict the geometric shape and thickness change during multi-pass tube spinning to a hemispherical shape. A computationally efficient, axisymmetric finite element model of the tube-spinning experiments is described. Uniaxial tensile tests are conducted for the development of the material model. The post-necking hardening curve is identified using a hybrid experimental-numerical method and represented by a combined Swift-Voce model. For validation of the finite element model, spinning experiments are performed at room temperature on thin-walled cylinders of 6061-O aluminum alloy. The experiments are interrupted after spinning passes 2, 4, 6, and 8 and the shape and thickness are measured. Also, local strain measurements on the final spun tube (pass 8) are accomplished by a scribed grid. By comparing the predictions to the experiments, good agreement is obtained on the shape, thickness, and strain evolution in multi-pass spinning. The deformation mechanism of this process is described by analyzing the history of plastic strain on an element of the numerical model.

Return Migration from Major Metropolitan Areas to Nagano Prefecture

In this paper, we try to focus the relationship between progress in information and communication technologies (ICTs) and the suburbanization of the office location.Information-related functions are located not only in the central business district (CBD) but also in the suburbs in Tokyo metropolitan area. Particularly conspicuous suburban locations are Yokohama area, Makuhari area and Tachikawa area, all of which are situated within some 30km from of the CBD.The Makuhari Shintoshin (new city) project has been successively promoted since 1989. To date, this new city is increasingly attracting information-related functions from the CBD, forming a new suburban office core. In terms of capital scale and business contents, these firms can be classified into the following three types. 1. Internet-related firms, 2. Back offices, 3. RD the suburbanization has thus made headway in order to secure office space. The pull factor appears to be the same for both internet-related firms and for back offices; namely, an abundant supply of high-quality information infrastructure, specifically intelligent buildings in Makuhari Shintoshin, which has served as a significant pull.In cases where major firms have constructed their own buildings and established the R&D sector, in particular, it is necessary to introduce changes in the corporate organization, which is distinctly different from the situation where single business establishments are relocated. Firms have constructed in Makuhari Shintoshi, with existing offices using a large-volume broad-band communications network, smooth in-house electronic data exchange has become possible leading to the development of an environment in which telecommunications can be actively introduced. For this reason, it is assumed that the "R&D sector", the sector that necessitates relatively little direct contact with clients, has been relocated from the CBD to the suburbs.This paper considered that the relationship between new ICTs and the suburbanization of office location on the basis of practical case study. It is generally understood that new ICT represents one of the factors behind the suburbanization of office location. This conclusion is consistent with previous case studies in Europe and the United States.Future studies will focus on comparing with another suburban core cities, because we continue to discuss that the standardization of relationship between progress in ICTs and the suburbanization of the office location.

The suburbanization of the office location due to progress in information and communication technologies

A new 32-channel pipeline TDC module, which implements custom-developed time memory cell LSIs, has been developed for high-rate wire-chamber applications. The module has achieved a 370 ps time resolution, and records data for a period of 3.2 /spl mu/sec. To handle the large data size, a digital signal processor (DSP56002) is implemented in the module. Most of the control logic is implemented in two complex PLDs to achieve a density of 32 channels in a single-width; double-height VME module.
