A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...
Dynamic cellular manufacturing systems, Mixed-integer non-linear programming, Production planning, Manufacturing attributes This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...
for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

This paper presents the design parameters for a single junction In0.5Ga0.5P solar cell using Silvaco ATLAS tool. Design parameters include thickness and doping concentration of the window, emitter and absorber layers. According to the simulation results, the absorber layer has the greatest effect on cell efficiency, and the emitter and window layers are in second and third positions, respective...
full adder cell is often placed in the critical path of other circuits. therefore it plays an important role in determining the entire performance of digital system. moreover, portable electronic systems rely on battery and low-power design is another concern. in conclusion it is a vital task to design high-performance and low-power full adder cells. since delay opposes against power consumptio...
This paper proposes a new sub-threshold low power 9T static random-access memory (SRAM) cell compatible with bit interleaving structure in which the effective sizing adjustment of access transistors in write mode is provided by isolating writing and reading paths. In the proposed cell, we consider a weak inverter to make better write mode operation. Moreover applying boosted word line feature ...
this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...
