Xxxviii. Metabolic Studies in Phenylketonuria

F6LLING [1934] discovered that, in certain cases of mental deficiency, phenylpyruvic acid was excreted in the urine. His attention was drawn to the phenomenon by the characteristic colour produced by the addition of ferric chloride solution to the urines of these patients, and he identified the responsible substance as phenylpyruvic acid. Other cases have since been recognized [Penrose, 1935]. ...

Thermal Unit Commitment Using Binary Differential Evolution

This paper presents a new approach for thermal unit commitment (UC) using a differential evolution (DE) algorithm. DE is an effective, robust, and simple global optimization algorithm which only has a few control parameters and has been successfully applied to a wide range of optimization problems. However, the standard DE cannot be applied to binary optimization problems such as UC problems si...

Tunable Multifunctional Thermal Metamaterials: Manipulation of Local Heat Flux via Assembly of Unit-Cell Thermal Shifters

Thermal metamaterials, designed by transformation thermodynamics are artificial structures that can actively control heat flux at a continuum scale. However, fabrication of them is very challenging because it requires a continuous change of thermal properties in materials, for one specific function. Herein, we introduce tunable thermal metamaterials that use the assembly of unit-cell thermal sh...

Thermal Unit Commitment Including Optimal AC Power Flow Constraints

We propose a new algorithm for unit commitment that employs a Lagrange relaxation technique with a new augmentation of the Lagrangian. The new augmentation involves a duplication of variables that allows relaxation of the coupling between generator timespanning constraints and system-wide instantaneous constraints. This framework allows the possibility of committing units that are required for ...
