Energy efficiency is an essential consideration in sustainable manufacturing. This study presents the car fender-based injection molding process optimization that aims to resolve the trade-off between energy consumption and product quality at the same time in which process parameters are optimized variables. The process is specially optimized by applying response surface methodology and using n...

Mainly composed of elastic materials, ship fenders are utilised on all kinds vessels for the protection berthing structures and prevention damage due to heavy crash loads. This study aims enhance deformation mode performance foam-filled under quasi-static dynamic loadings. Six models fender’s structure chosen simulation test. The examined crashworthiness parameters such as crushing force effici...

For both the expansion of important islands/reefs and development marine resources in South China Sea, a modular integrated floating structure (MIFS) system with tidal self-adaptation dolphin-fender mooring (DFM) has been proposed. The DFM, coupled wave energy converters (WEC), can serve as an anti-motion system. Considering modules’ hydrodynamic interaction effect connectors’ mechanical coupli...

The mathematical modelling of sheet metal forming operation is extended to include information about the particular tool and the particular machine that will be used in the "real" process. Particular attention is paid to the structure and to the operation of a mechanical press. For this type of process some control factors (parameters that the engineer can set during the fine tuning of the form...

We calculate the jet power of the classical Blandford-Znajek (BZ) model and hybrid model developed by Meier (2001) based on the global solutions of advection dominated accretion flows (ADAFs) surrounding Kerr black holes. We find that the jet power of the hybrid model is larger than that of the pure BZ model. The jet power will dominate over the accretion power and the objects will enter into “...

The southern pines constitute an important commercial crop, and with proper management their rapid growth insures a renewable resource for the southern United States. On upland pine sites, hardwood shrubs and trees, herbaceous plants, and woody vines all compete with the pines for sunlight, growing space, moisture, and nutrients. The loss in pine volume production that results from this competi...
