Differential interferogram images derived from repeat-pass spaceborne Synthetic Aperture Radar (SAR) systems give the possibility to map surface deformations of small spatial extent and to monitor their spatiotemporal evolution. A slow and local phenomenon of subsidence caused by underground coal mining has been observed near Gardanne, France, from images acquired by both European ERS-1/2 satel...

A radical, new innovation with regards to forestry machines is the design of a cab suspended from an arched column connected to a swiveling socket. The purpose of the design is to reduce the amount of skewed and twisted work postures, which are often frequent among operators of logging machines. The ability to sit straight is what most operators point out to be the most desirable feature of the...

Hard metals are an important material due to their specific properties, such as high degree of hardness and resistance to abrasive wear, and they are in wide use today. There are indications that hard metal aerosols can endanger human health. Discussions are ongoing as to how to categorize hard metals as hazardous as a result. This categorization will require deciding in particular how to deter...

— This paper investigates intermediate input effects and labor pooling in the context of urban informality, examining the handicraft industry of Nairobi, Kenya. The paper tests if conditions found in informality interfere with transition pathways in production clusters. 102 semi-structured interviews were conducted with industry participants, including 69 production firms. Findings confirm the ...

Sink nodes are the data centers of wireless sensor networks (WSNs), and the storage management scheme for such nodes is vital, particularly in applications such as wireless multimedia sensor networks that involve the collection of massive amounts of data. NAND flash memory is often employed in sink nodes because of its excellent characteristics. Because the lifetime of NAND flash memory is high...

The high luminosity delivered by LEP after the doubling of the e+e− collision energy means that LEP2 is now providing substantial samples of W bosons with which tomake complementary tests of the Standard Model to those of LEP1. This, together with collision energies in excess of 200 GeV, is ensuring that the three central physics goals of the LEP2 program are properly explored: the precise meas...
