Shrimp shell waste are potential to be processed further into value-added products, such as N-acetylglucosamine (GlcNAc). In the production of GlcNAc, biological approach is preferred and environmentally friendly chemical treatment. Chitinase an enzyme that plays a vital role in bioprocessing shrimp GlcNAc. Previously, Bacillus cereus SMG 1.1 was isolated from fermented paste (terasi) showed ab...

Productivity is of major economic significance in the current competitive global market. Due to growing costs and globalization of the marketplace, improvements in productivity require the creation of a reliable design through concurrent systems analysis in the shortest possible time. This is particularly important for designing complex engineering systems such as aircraft, automobiles and ship...

This toolkit provides a set of tools for automatically creating a response surface for a target design space. Response surfaces are equations that express a performance metric used to evaluate a set of possible designs in terms of the designs’ parameters. If you can parameterize your design and quantify a performance metric of interest to you then this toolkit can vastly reduce the number of hi...

The inset-surface permanent magnet (ISPM) machine can achieve the desired electromagnetic performance according to traditional deterministic design. However, reliability and quality of may be affected by essential manufacturing tolerances unavoidable noise factors in mass production. To address this weakness, a comprehensive multi-objective optimization design method is proposed, which robust p...

This paper considers the control of the longitudinal flight dynamics of an F-16 aircraft. The primary design objective is model-following of the pitch rate q, which is the preferred system for aircraft approach and landing. Regulation of the aircraft velocity V (or the Mach-hold autopilot) is also considered, but as a secondary objective. The problem is challenging because the system is nonline...

When mechanically induced progressive failure of rock and the associated changes in hydro fracturing process, it is difficult to track the dynamic evolution of fractures beneath the earth. To overcome this, recent developments in hydro-fracturing technique have tended to follow hybrid approaches. An attempt was made to develop an empirical relationship to predict the Fracture length in millimet...

Optimizing parameter settings is an important task in algorithm design. Several automated parameter tuning procedures/configurators have been proposed in the literature, most of which work effectively when given a good initial range for the parameter values. In the Design of Experiments (DOE), a good initial range is known to lead to an optimum parameter setting. In this paper, we present a fra...
