In view of the increasing concerns over non-renewable resource depletion and waste management, this paper studied development low-density controlled low-strength material (CLSM) by using stone sludge lightweight aggregates. First, investigation was performed at a laboratory scale to assess effects composition on properties resulting CLSM. The Taguchi method with an L9(34) orthogonal array four ...

Austenitic stainless steel is a popular material for its corrosion resistant properties, however it has low hardness which limits application. Low-temperature carburizing can be used to improve the mechanical properties of austenitic by producing expanded austenite layer. In order get high-quality layer and an efficient processing operation, process must optimized. this research, Taguchi method...

Background: Xanthomonas citri subsp. citri (Xcc), the causative agent of bacterial citrus canker, has affected citriculture worldwide. Varieties of means have been used to minimize its devastating effects, but no attention has been given to bacteriocins. Objectives: Here and for the first time, we report the isolation and characterization of two novel bacteriocins. Materials and Methods: Secret...

This paper introduces optimization of machining parameters for high-pressure abrasive water jet cutting Hardox 500 steel utilizing desirability function analysis (DFA). The tests were carried out according to the orthogonal matrix (Taguchi) L9. control process such as pressure, flow rate, and traverse speed was optimized under multi-response conditions namely depth surface roughness. optimal se...

In the present study, a comparison of central composite design (CCD) and Taguchi method was established for Fenton oxidation. [Dye]ini, Dye:Fe(+2), H2O2:Fe(+2), and pH were identified control variables while COD and decolorization efficiency were selected responses. L 9 orthogonal array and face-centered CCD were used for the experimental design. Maximum 99% decolorization and 80% COD removal e...

In this paper, the heat transfer to the fluid, passing through the double forward facing step (FFS) channel with square obstacle is enhanced by Taguchi’s S/N ratio analysis. Flow through the forward facing step channel has a wide range of applications in thermal systems due to its flow separation and subsequent reattachment, which in turn enhances the heat transfer. Flow separation and reattach...

This present work is aimed to optimize the machining parameters and study effect of powder mixed dielectric fluid on EDM process. TOPSIS method optimization adopted identify optimal parameters. HCHCr die steel preferred as material. Ni, Zr Ni+Zr were selected inclusion in due hard ductile nature. L9 array Taguchi DOE perform experiments with like peak off time, pulse time current. revealed that...

One of the major steps toward the industrialization of the microbial product(s) is to optimize the cultivation conditions at the large-scale bioreactor and successfully control the microbial behavior within a large scale production environment. Statistical Design of Experiment was proven to optimize a vast number of microbial processes to achieve robustness and explore possible interactions...

The operating control parameters of injection flushing type of electrical discharge machining process on stainless steel 304 workpiece with copper tools are being optimized according to its individual machining characteristic i.e. material removal rate (MRR). Lower MRR during EDM machining process may decrease its’ machining productivity. Hence, the quality characteristic for MRR is set to high...
