Two trials were conducted to study the effect of multi-steps phase-feeding (PF) program on growth performance of broiler chickens from 1 to 24 and 1 to 39 d of age. The control group was the nutrient recommendation of Aviagen (2019) with a three-step PF program (1-10, 11-24 and 25-39 d of age). In the first trial, the control group was compared with an eight-step PF program (PF8), and in the se...

Every accelerator or storage ring system consists of a charged particle beam propagating through a beam line. Although a number of computer programs exist that simulate the propagation of a beam% a given beam line, only a few provide the capabilities for designing, commissioning and operating the beam line. This paper shows how a “multi-track” simulation and analysis code can be used for these ...

The spot-diffusing technique provides better performance compared to conventional diffuse system for indoor optical-wireless communication (OWC) system. In this paper, the performance of an OW spot-diffusing communication system using Neuro-Fuzzy (NF) adaptive multi-beam transmitter configuration has been proposed. The multi-beam transmitter generates multiple spots pointed in different directi...

the rapid melting of a semi- infinite body due to the absorption of a cw laser beam radiation has been studied. the enthalpy technique for the solution of phase change problems has been used in an explicit finite difference form to calculate the transient temperature distribution in the semi-infinite body and the growth rate of the melt pool. the technique has been modified so that it is not ne...

The time dependence of B d B d mixing has been observed in events containing high-P t leptons using a highly inclusive v ertexing method to determine the B decay position. The initial state B hadron avor was determined using the large forward-backward asymmetry provided by the highly polarized electron beam of SLC in combination with a jet charge technique. From a sample of 150,000 hadronic Z d...

Electron microscopy has shown to be a very powerful tool to map the chemical nature of samples at various scales down to atomic resolution. However, many samples can not be analyzed with an acceptable signal-to-noise ratio because of the radiation damage induced by the electron beam. This is particularly crucial for electron energy loss spectroscopy (EELS) which acquires spectral-spatial data a...

In the JLab Electron Ion Collider (JLEIC) project the traditional electron cooling technique is used to reduce the ion beam emittance at the booster ring, and to compensate the intrabeam scattering effect and maintain the ion beam emittance during collision at the collider ring. A new electron cooling process simulation program has been developed to fulfill the requirements of the JLEIC electro...

Multi-beam heavy-ion accelerators are considered as promising drivers for inertial fusion energy. The High Current Experiment (HCX) at Lawrence Berkeley National Laboratory (LBNL) will test driver-scale beam dynamics in a single transport channel. Single bore, NbTi superconducting quadrupoles are being developed for the HCX, taking into account their possible use as modules in a quadrupole arra...
