Thermal and mechanical assessments of the 3D-printed conformal cooling channels : computational analysis and multi-objective optimization
Published 2021“…As for the circular channel, the coolant temperature, volume flow rate, and channel diameter are selected as the parameters within the ranges of 288.0-298.0 K, 1.0-10.0 L/min, and 2.1-2.5 mm, respectively. According to these parameters, the multi-objective optimization study is performed and the best trade-off point is found at the channel diameter of 2.5 mm, coolant temperature of 297 K, and the flow rate of 1 L/min when all the objectives have equal weights in the optimization problem.…”

Numerical methods for finite-size key rates with different entropic bounds in quantum key distribution
Published 2024“…Following the ideas of Dupuis, we also formulated a generalized alpha-Renyi entropic bound on the secret key rate under i.i.d. collective attack, and showed regions of improvement from the conventional approach of using the smooth min-entropy. In particular, we proposed a generalized optimization method for the Renyi entropy for alpha = (1,2] and the min-entropy by adapting from Winick et al.'…”

Electrospinning of low density PCL fibers on SLS scaffold
Published 2010“…The parameters to produce low density PCL scaffold of 0.5-1um diameter fibers were established to be acceleration voltage= 25kV, feed rate= 0.5ml/h, rotational speed= 1500rpm and time= 1min. On the other hand, electrospinning with the same duration of 1min produces a higher density scaffold while varying acceleration voltage to 15kV and feed rate of 10ml/h; 8-10um fibers were obtained. …”

Multi-valued logic synthesis for Resistive Random Access Memory (RERAM) based in-memory computing
Published 2018“…The synthesis of multivalued functions consists of bi-decomposition or functional decomposition of the given target function to obtain a multilevel network comprising of MIN and MAX gates. Synthesis tools, such as YADE and those based on Multi-valued decision diagrams make the implicit assumption regarding the availability of literals or CASE operator, while focusing on the optimization of the logic network solely based on the MIN and MAX gates. …”
