Ceramics is an important engineering material. Its characteristics, such as brittleness and hardness, post difficulty when it is being processed with high precision. Grinding is one of the methods to finish parts with high accuracy. However, it is necessary to control the grinding force to achieve the desired surface quality of ceramics parts. In this paper, we present the study results of the influence...
In this paper we proposed a novel adaptive distributed wavelet compression (ADWC) algorithm for reducing energy consumption in a wireless sensor network, where each of the sensors has limited power. This algorithm is characterized by a distributed lifting factorization, which matches well with the transmission strategy employed in wireless sensor networks. It also presents an adaptive algorithm to...
Blepharocalyxins A and B (1 and 2), novel natural products having two diarylheptanoids and a chalcone moiety were isolated from the seeds of Alpinia blepharocalyx K. Schum. The structures of these compounds were elucidated by intensive study of the 2D NMR spectroscopy. These compounds inhibited nitric oxide production in endotoxin-activated murine macrophages, J 774.1.
