In this paper the effect of wall waviness of side walls in a two-dimensional wavy enclosure is numerically investigated. Two vertical wavy walls and straight top wall are kept isothermal and the bottom wall temperature is higher and spatially varying with cosinusoidal temperature distribution. A computational code based on Finite-volume approach is used to solve governing equations and SIMPLE m...

Whenever a tuned-mass damper is attached to a primary system, motion of the absorber body in more than one degree of freedom (DOF) relative to the primary system can be used to attenuate vibration of the primary system. In this paper, we propose that more than one mode of vibration of an absorber body relative to a primary system be tuned to suppress single-mode vibration of a primary system. W...

We present an XMM-Newton observation of NGC 7469, including studies of the X-ray and UV variability, 0.2−10 keV spectral continuum, Fe Kα emission line and the first-ever high-resolution X-ray spectrum of the soft X-ray warm absorber. We compare the properties of this X-ray warm absorber with the UV warm absorber as seen in a FUSE observation one year previously. The 0.2−10 keV spectral continu...

Biopsy of the lesion at scanning power shows laminar hyperkeratosis of the epidermis, slight irregular acanthosis, and a perivascular lymphocytic inflammatory infiltrate in the papillary and superficial reticular dermis (Fig. 3), in the mid reticular dermis there is an unencapsulated, poorly defined neoplasm, consisting of a symmetrically arranged proliferation of wavy spindle cells in fascicle...

Manipulation of the configuration of Ag nanowire (NW) networks has been pursued to enhance the performance of stretchable transparent electrodes. However, it has remained challenging due to the high Young's modulus and low yield strain of Ag NWs, which lead to their mechanical failure when subjected to structural deformation. We demonstrate that floating a Ag NW network on water and subsequent ...

A numerical model is developed to quantify the effects of hydrodynamics on heat and mass transfer during an absorption, for a laminar film flowing over a wavy wall column. First of all, the modelling is written for a single wave of the wall shape. Then, an experimental set up, composed of a CCD video camera, validates this model. Finally, the model is extended to an entire column. The results i...

The high efficiency of monocoque cylindrical shells in carrying axial loads is curtailed by their extreme sensitivity to imperfections. For practical applications, this issue has been alleviated by introducing closely stiffened shells which, however, require expensive manufacturing. Here we present an alternative approach that provides a fundamentally different solution. We design symmetry-brea...

Microscopic billow-like wavy folds have been observed along slip planes of the Nojima active fault, southwest Japan. The folds are similar in form to Kelvin–Helmholtz (KH) instabilities occurring in fluids, which implies that the slip zone underwent “lubrication” such as frictional melting or fluidization of fault gouge materials. If the temperature range for generation of the billow-like wavy ...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

We have investigated the validity of our simulator. The validation item that we have already performed are summarized as follows. 1. Whether the energy loss distribution follows the Landau’s distribution. • thin absorber of Silicon 2. Whether the energy loss along per unit length follows the formula of Bethe-Bloch for protons. • thick absorber of Silicon • thick absorber of Lead 2 Landau’s dist...
