Abstract In recent years, 3D technology has been widely used in various aspects of the entire workflow conservation–restoration. However, majority cases, researchers have mainly relied on technologies to assist conventional conservation–restoration process, and its advantages not truly exploited. this paper, we applied a combination digital acquisition, virtual anastylosis, reconstruction, prin...
Liquid food packages consist of various polymers films, which are bonded together with Aluminum foil (Al-foil) using adhesion or by direct heat. The main aim this research was to define important material properties such as fracture toughness and some FE-simulation model parameters damage initiation, evolution, the between Al-foil low-density polyethylene (LDPE) film. This investigation is base...
A novel relational learning approach that tightly integrates the naı̈ve Bayes learning scheme with the inductive logic programming rule-learner FOIL is presented. In contrast to previous combinations that have employed naı̈ve Bayes only for post-processing the rule sets, the presented approach employs the naı̈ve Bayes criterion to guide its search directly. The proposed technique is implemented in...
A simple method for penetrating the barrier layer of an anodic aluminum oxide (AAO) film and for detaching the AAO film from residual Al foil was developed by reversing the bias voltage in situ after the anodization process is completed. With this technique, we have been able to obtain large pieces of free-standing AAO membranes with regular pore sizes of sub-10 nm. By combining Ar ion milling ...
Direct microjoining using Yttrium-Aluminium-Garnet (YAG) laser beams of copper wire and a plate or substrate board was carried out. The control of the behavior of the molten wire was extremely important to prevent joining defects such as evaporation or constriction of the wire. Both the contact angle between the wire and the plate and the distance from the tip of the wire to the laser irradiati...
We present a general approach to growing ZnO nanowires on arbitrary, high melting point (above 970 degrees C) substrates using the vapor-liquid-solid (VLS) growth mechanism. Our approach utilizes the melting point reduction of sufficiently small (5 nm diameter) Au particles to provide a liquid catalyst without substrate interaction. Using this size-dependent melting effect, we demonstrate catal...
2014 The energy straggling of heavy ion beams at tandem energies, passing through thin foils, has been studied with ions of mass up to A = 35. Charge exchange in the foils has been found to have a considerable effect on the energy spread. Thickness non-uniformities in the foils can also make significant contributions. Extrapolation of the observations to the case of a uniform carbon stripper fo...
