During recent history in the United States, government systems development has been performance driven. As a result, systems within a class have experienced exponentially increasing cost over time in fixed year dollars. Moreover, little emphasis has been placed on reducing cost. This paper defines designing for cost and presents several tools which, if used in the engineering process, offer the...

Original scientific paper This paper has presented and discussed machinability in the drilling of SMC (Sheet Mould Compound) A-Class composite materials using Taguchi's DoE method. The thrust forces, surface roughness and push-out peel-up delamination behaviour in drilling process for glass fibre reinforced SMC composites have been evaluated. The experimental results and the contribution ratio ...

The ever-increasing complexity of software systems makes them hard to comprehend, predict and tune due to emergent properties and non-deterministic behaviour. Complexity arises from the size of software systems and the wide variety of possible operating environments: the increasing choice of platforms and communication policies leads to ever more complex performance characteristics. In addition...

Eucalyptol (1,8-cineole) compound contained in eucalyptus oil has the potential to inhibit viral infection pathways, as an antimicrobial and immunoregulator. Therefore, development of oil-based effervescent health drinks is urgently needed relieve symptoms being infected a virus during this pandemic. However, volatility quite high, so nano-based encapsulation method slow release these volatile ...

Pure aluminium poses inferior properties that limit its use in load-bearing applications. Reinforcing multiwall carbon nano-tube (solid lubricant) and graphene to matrix offers better (antifriction, hardness, wear resistance) composites for such A stir casting processing route is employed prepare the hybrid composite (aluminium-multiwall nanotube-graphene Al-MWCNT-GR). The Taguchi L16 experimen...

This paper describes a comparison of tool life between ceramics and cubic boron nitride (CBN) cutting tools when machining hardened steels using the Taguchi method. An orthogonal design, signal-to-noise ratio (S/N) and analysis of variance (ANOVA) were employed to determine the effective cutting parameters on the tool life. The results indicated that the V was found to be a dominant factor on t...

The machining of thin-walled double side freeform component has many challenges in terms of the geometrical complexity, high-requirement accuracy, and especially low stiffness. This paper surveys the filling method during the milling processes of thin-walled double side freeform component. Firstly, the DEFORM-3D was used to analyze and calculate the surface residual stress which provides a theo...

The practical applications of integrated maintenance policies and quality for a multi-component system are more complicated, still rare, incomplete to meet the requirements Industry 4.0. Therefore, this work aims extend integration economic model optimizing control parameters by incorporating Taguchi loss function system. An optimization is developed based on preventive maintenance, corrective ...

Motivation Loss-of-function genetic variants are frequently associated with severe clinical phenotypes, yet many are present in the genomes of healthy individuals. The available methods to assess the impact of these variants rely primarily upon evolutionary conservation with little to no consideration of the structural and functional implications for the protein. They further do not provide inf...
