This paper studies the temperature field, dynamic strain, and forming accuracy of oscillate-WAAM conical shell in process manufactures WAAM part. The results show that compared with offset filling WAAM, shows following characteristics: difference value between inner outer walls is significantly reduced, cooling rate doubled decreased, interlayer above 300 °C, average gradient, strain stability ...

Abstract Quantum Dot Infrared Photodetector (QDIP) is one of the promising candidates for infrared photodetection due to its controllable heterojunction bandgap and sensitivity normal incident radiation. It expected be superior photodetectors mature technologies such as Mercury Cadmium Telluride (HgCdTe) or a quantum well photodetector. In presented paper, we have developed theoretical model da...

The story of the "cylindrical saxophone" started with Benade (1988). The basic idea is that when the length of the missing part of a truncated cone is smaller than the wavelength, and therefore smaller than the length of the truncated cone, the behavior of a conical reed instrument has similarities with that of a cylindrical pipe excited by a reed on its side, at an intermediate location. The s...

A method for solving the shell-model eigenproblem in a severely truncated space, spanned by properly selected correlated states obtained by partitioning the full configuration space, is proposed. The method describes in a practically exact way the low energy spectroscopic properties of nuclei, as exemplified in schematic models. The applicability of the method to heavy nuclei as well as in cont...
