When stretched uniaxially, a thin elastic sheet may exhibit buckling. The occurrence of buckling depends on the geometrical properties of the sheet and the magnitude of the applied strain. Here we show that an elastomeric sheet initially stable under uniaxial stretching can destabilize when exposed to a solvent that swells the elastomer. We demonstrate experimentally and computationally that th...

In this paper, we introduce the latest results of our two-dimensional communication project. The communication elements that touch the surface of a Two-Dimensional Signal Transmission (2DST) sheet establish the connection being supplied with the power by the 2DST sheet. The system allows free location of the element, and proximity (non-contact) connection is realized stably. The structure of 2D...

We present a sheet structure that rotates the local ray direction through an arbitrary angle around the sheet normal. The sheet structure consists of two parallel Dove-prism sheets, each of which flips one component of the local direction of transmitted light rays. Together, the two sheets rotate transmitted light rays around the sheet normal. We show that the direction under which a point ligh...

An analytical expression for the eddy current forces on a circular current loop moving with constant velocity over a thin conducting sheet is derived in this paper. This calculation is based on using the boundary conditions across the conducting sheet to solve for the total magnetic vector potential. The eddy currents in the sheet and the forces on the sheet are first presented in the ‘quasista...

be geared to modern requirements. Unlike the present solvency regime, Solvency II is designed to reflect a prospective and risk-oriented economic view. It will be based on a total balance sheet approach and harmonised with accounting rules and regulations. Assets and liabilities will consistently be recognised at market values. In principle, IFRS provisions can be used as a basis for valuing th...

A stretchable cm electromagnetic interference (EMI) measurement sheet is developed to enable the measurement of EMI distribution on the surface of electronic devices by wrapping the devices in the sheet. The sheet consists of an 8 8 coil array, a 2 V organic CMOS row decoder and a column selector, 40% stretchable interconnects with carbon nanotubes, and 0.18 m silicon CMOS circuits for electric...

We present a reference, comprehensive, high-resolution, digital mosaic of ice motion in Antarctica assembled from multiple satellite interferometric synthetic-aperture radar data acquired during the International Polar Year 2007 to 2009. The data reveal widespread, patterned, enhanced flow with tributary glaciers reaching hundreds to thousands of kilometers inland over the entire continent. Thi...

In the present paper the corrosion properties of structured sheet metals were investigated. The aim of this work is to determinate the influence of the structuring process on the corrosion resistance of sheet metals. For this purpose, these sheets were examined by accelerated tests in corrosion chamber. The investigation was carried out using salt spray test. The experiment was conducted for th...

Accurate thickness measurement of sheet-like structure such as articular cartilage in CT images is required in clinical diagnosis as well as in fundamental research. Using a conventional measurement method based on the zero-crossing edge detection (zero-crossings method), several studies have already analyzed the accuracy limitation on thickness measurement of the single sheet structure that is...

The northeast Greenland ice stream (NEGIS) was discovered as a large fast-flow feature of the Greenland ice sheet by synthetic aperture radar (SAR) imaginary of the ERS-1 satellite. In this study, the NEGIS is implemented in the dy-namic/thermodynamic, large-scale ice-sheet model SICOPOLIS (Simulation Code for 5 POLythermal Ice Sheets). In the first step, we simulate the evolution of the ice sh...
