Regional Economic Resilience: Review and Outlook

by

Regional Economic Resilience: Review and Outlook by Simone Maria Grabner.

This chapter aims, first, to trace the advancement of resilience thinking in regional science and economic geography. Second, highlight achievements but also some shortcomings past research on resilience, third, outline elements a future agenda suited contemporary challenges. The in-depth analysis literature suggests, that much progress has been made defining identifying determinants. However, paper proposes may benefit greatly from diversifying focus empirical studies incorporating socio-economic differences between urban rural areas urbanisation externalities into resilience.

Economic UPS structure with phase-controlled battery charger and input-power-factor improvement

by

Economic UPS structure with phase-controlled battery charger and input-power-factor improvement by Wen-Jung Ho, Jan-Bin Lio, Wu-Shiung Feng.

A new single-phase uninterruptible power supply (UPS) scheme is proposed. Its advantages when compared with existing UPSs are: no transferring time, high efficiency, low implementation cost and density. It mainly consists of a minimised converter which capable providing specified constant output voltage, phase-controlled battery charger, input-power-factor improvement. The experimental results the developed prototype show superior performance.

AUSTRALIAN BROWN COAL/OIL MIXTURES AS A FUEL FOR DIESEL ENGINES; ENGINE PERFORMANCE AND ECONOMIC VIABILITY by R.J. Downie, P.C. Bandopadhayay.

ABSTRACT CSIRO Division of Energy Technology has used mixtures finely ground, chemically beneficiated, Australian brown coal (up to 30% by weight, maximum particle size less than 13 microns) and automotive diesel oil (ADO) fuel an essentially unmodified single cylinder engine operating at 800, 1200 1500 r/min. Engine performance tests indicate that can be as a extender reduce consumption the conventional liquid (ADO). Partially burnt agglomerates were identified in exhaust there indications late burning higher speeds concentrations. brake thermal efficiency ratio is important parameter when evaluating economic viability new fuels for internal combustion engines. A simple model based on ‘payback period’ developed assess converting existing powered plant operate coal/oil mixture fu…

How Size Determines the Value of Gold: Economic Aspects of Wet Chemical and Laser-Based Metal Colloid Synthesis by Sandra Jendrzej, Bilal Gökce, Matthias Epple, Stephan Barcikowski.

Gold is one of the most valuable materials, and its monetary value enhanced by size reduction from bullions to colloidal nanoparticles a factor 450. Wet-chemical with subsequent centrifugation pulsed laser ablation in liquids are frequently used for pure gold synthesis. Both methods provide similar physicochemical nanoparticle properties, but very different synthesis techniques. However, costs inherent these surprisingly seldom discussed. have common that labor effort poses majority costs. Besides an increase batch mass concentration, especially productivity via higher power capacity reduces if pilot- or industrial-scale applications intended. In this case, laser-based more economical exceeds break-even 550 mg h-1 , where arising limited metal contrast industrial scale production, wet-chemical feasible laboratory-scale applications, advantageous properties provided not needed.
