In this study,6-chloro-4-hydroxy-2-quinolone and 6-flouro-4-hydroxy-2-quinolone were synthesized from corresponding dianilides.These compounds were coupled with
A series of 4,6,7,8-tetrahydro-2,5-(1H,3H)-quinolinediones was prepared from ethyl-2-cyanoacetate, aromatic aldehydes and 1,3-cyclohexanedione or 5,5-dimethyl-1
We consider that the reserve of an insurance company follows a renewal risk process with interest and dividend.For this risk process,we derive integral equation
This paper proposes a multilevel placer targeted at hierarchical FPGA(Field Programmable Gate Array)devices.The placer is based on multilevel optimization metho
We measured the water content (0.01%-0.25%w/w) in crude oil emulsions using terahertz time-domain spectroscopy (THz-TDS). To improve the precision and range of
