Advance Journal of Food Science and Technology , 2013,
Abstract: The aim of this study was mainly on apply immobilized trypsin which covalently linked with chemically modified chitosan-coated Fe3O4 particles to producing the antihypertensive peptide by hydrolyzing peanut protein. Response Surface Methodology (RSM) was employed to optimize the hydrolysis conditions, including Enzyme/substrate ratio, temperature, pH and time. Results showed that enzyme immobilization technology improved the thermal and pH stability of trypsin. The minimum IC50 value for Angiotensin Converting Enzyme (ACE) inhibitory activity (0.76 mg/mL) was obtained at the E/S ratio of 3.52, the temperature of 54.65°C, the time of 2.95 h and pH of 8.43, which was agreement with the predicted value (0.77 mg/mL) estimated by RSM within a 95% confidence interval. Moreover, a modest increase in the degree of hydrolysis promoted the ACE inhibitory activity of the hydrolysates, but excessive hydrolysis would lead to a decrease in ACE inhibitory activity.
HSM2:A New Heuristic State Minimization Algorithm for Finite State Machine
HSM2: A New Heuristic State Minimization Algorithm for Finite State Machine

Abstract: This paper proposes a heuristic state minimization algorithm (HSM2) for finite state machines (FSM). HSM2 focuses on the generation and adjustment of the closed cover. First an initial closed cover is generated by heuristically selecting proper maximal compatibles to satisfy all the covering and closure conditions, and then it is adjusted to be a minimal or near minimal closed cover by heuristically removing repeated states. Experimental results show that the algorithm is faster and obtains better or the same solutions compared with conventional methods.
Scheduling with Resource Allocation for System-Level Synthesis

软件学报 , 2007,
Abstract: In system-level synthesis, the allocation of resources is always decided by the designer or explored in the outer-most loop. In this paper, a heuristic scheduling algorithm is proposed to find the resource allocation during its running process. It determines the appropriate number of required resource instances based on the system partition in scheduling, and generates the corresponding resource allocation, scheduling and assignment solution. Such an algorithm can simplify the system-level design exploration to a procedure of system partitioning, scheduling and evaluation, and can improve the exploration efficiency. Experimental results show the feasibility and validity of the approach.
