Low computational cost semi-analytical magnetostatic model for magnetocaloric refrigeration systems

A New Method for Improving Computational Cost of Open Information Extraction Systems Using Log-Linear Model

Information extraction (IE) is a process of automatically providing a structured representation from an unstructured or semi-structured text. It is a long-standing challenge in natural language processing (NLP) which has been intensified by the increased volume of information and heterogeneity, and non-structured form of it. One of the core information extraction tasks is relation extraction wh...

Large magnetocaloric effect and adiabatic demagnetization refrigeration with YbPt2Sn

Adiabatic demagnetization is currently gaining strong interest in searching for alternatives to (3)He-based refrigeration techniques for achieving temperatures below 2 K. The main reasons for that are the recent shortage and high price of the rare helium isotope (3)He. Here we report the discovery of a large magnetocaloric effect in the intermetallic compound YbPt2Sn, which allows adiabatic dem...

Preliminary Analysis of a Fully Solid State Magnetocaloric Refrigeration

Magnetocaloric refrigeration is an alternative refrigeration technology with significant potential energy savings compared to conventional vapor compression refrigeration technology. Most of the reported active magnetic regenerator (AMR) systems that operate based on the magnetocaloric effect use heat transfer fluid to exchange heat, which results in complicated mechanical subsystems and compon...

On Tailored Model Predictive Control for Low Cost Embedded Systems with Memory and Computational Power Constraints

Even though many efficient formulations and implementations exist by now, predictive control on low cost embedded systems with constrained memory and computing power is still challenging. We present an algorithm combining Nesterov’s gradient method and the method of multipliers for linear model predictive control, which can exploit the structure and does not need slack variables. Moreover, we d...
