Charge Scheduling of Electric Vehicles for Last-Mile Distribution of an E-grocer

This paper proposes a model for charge scheduling of electric vehicles in last-mile distribution that takes into account battery degradation. A mixed integer linear programming formulation is proposed that minimizes labor, battery degradation and time-dependent energy costs. The benefit of implementing charge schedule optimization is assessed...

Improvements in separation of non-ferrous scrap metals using an electromagnetic sensor

This article describes a new method for identification and separation of non-ferrous scrap metals using an electromagnetic sensor that is based on the eddy current principle. The electromagnetic sensor (EMS) is a prototype system that has been developed by Delft University of Technology in co-operation with industry. Experimental results...

A method and apparatus for analysing and sorting a flow of material

The invention relates to a method and an apparatus for analysing a flow of material using X rays. The method comprises radiating the material with at least two energy levels and measuring the transmission of radiation through the material for each level separately, and is characterized in that a sensor is used for measuring the radiation...

Werkwijze voor het scheiden van deeltjes in een vloeibaar medium en een inrichting daarvoor

Particles in a fluid medium are separated by feeding a mixture of particles into a separation chamber. The mixture of particles is treated by moving the medium up and down relative to the mixture of particles. A barrier is present above the mixture to restrain the particles. An Independent claim is also included for an apparatus for separating...
