The objective of this investigation was to find a simple method for the production of phenolic rich products and sugar derivatives (biopolyols) via separation of liquefied lingocellulosic materials. Liquefaction of lignocellulosic materials was conducted in methanol at 180 °C for 15 min with the conversion of raw materials at about 75%. After liquefaction,(More)
It has been considered most important and difficult to analyze the bias and find a large bias regarding the security of crypto-systems, since the invention of linear cryptanalysis. The demonstration of a large bias will usually imply that the target crypto-system is not strong. Regarding the bias analysis, researchers often focus on a theoretical solution(More)
—Task partition is a NP-Hard problem on multi-core processor. To achieve a good MCT (maximum completion time) goal, this paper presents a novel task partitioning method for multi-core processor based on the cohesion and coupling properties of tasks. First, the relations between the cohesion and coupling are analyzed and the computation method of coupling(More)
Liquefaction of sawdust was studied in methanol−water solutions using an acid catalyst under microwave energy. The effect of the methanol concentration on the changes of components in the liquefied products was analyzed by gas chromatography−mass spectrometry (GC−MS). It was found that 5-hydroxymethylfurfural (HMF) and levulinic acid are the dominate(More)
Reputation is a primary mechanism for trust management in decentralized systems. Many reputation-based trust functions have been proposed in the literature. However, picking the right trust function for a given decentralized system is a non-trivial task. One has to consider and balance a variety of factors, including computation and communication costs,(More)
