In the process of milling profile vanes a gas turbine engine on multi-operational machines, technological scheme transverse line shaping is used. According to this scheme, vane rotates around its own axis, it machined with mill spherical working surface, which performs rotation and interpolated axial movement. The required parameters surface quality airfoil (profile accuracy roughness parameter...

This study aimed to establish a method identify the geographical origin of milk based on its amino acid profile. High-performance liquid chromatography (HPLC) was carried out measure contents. The significant differences profiles samples from four regions in China (Hebei, Ningxia, Heilongjiang, and Inner Mongolia) were analyzed by ANOVA. Furthermore, principal component analysis (PCA) demonstra...

between these pathways. To do so we need to observe the activity of the direct and indirect pathway spiny projection neurons in “behaving” animal models (1). However, it is difficult to distinguish direct and indirect spiny projection neuron firing using electrophysiological recordings and antidromic stimulation is unreliable and difficult due to “cross talk” between axons of both pathways (1)....

Kilovoltage (kV) cone beam computed tomography (CBCT) images suffer from a substantial scatter contribution. In this study, Monte Carlo (MC) simulations are used to evaluate the scattered radiation present in projection images. These predicted scatter distributions are also used as a scatter correction technique. Images were acquired using a kV CBCT bench top system. The EGSnrc MC code was used...

BACKGROUND Metal artifacts appearing as streaks and shadows often compromise readability of computed tomography (CT) images. Particularly in a dental CT in which high resolution imaging is crucial for precise preparation of dental implants or orthodontic devices, reduction of metal artifacts is very important. However, metal artifact reduction algorithms developed for a general medical CT may n...

different methods exists for jamming mitigation and we should choose a method based an the jammer type and other parameters. one of the jammers is narrow band fm jammer and we use subspace projection techniques for the suppression of this type of jammer. in subspace projection technique, we estimate the if of signals and construct the subspace vector that is orthogonal to jammer vector by incre...
