Optimal Management of a Wind/CAES Power Plant by means of Neural Network Wind Speed Forecast

, 2007
Some of the major limitations of renewable energy sources are represented by their low power density and intermittent nature, largely depending upon local site and unpredictable weather conditions. These problems concur to increase the unit costs of wind

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

Thresholds: The metaphorical foundations of powerful knowledge

The Curriculum Journal, EarlyView.
Abstract This paper advances a theoretical account of threshold concepts as metaphorical‐relational structures that reorganise meaning across contexts. Building on conceptual metaphor theory, we propose that threshold concepts can be understood as sites of schema‐level reorganisation: deep, embodied patterns of relational logic that scaffold abstract ...
