Recovering boundary conditions in inverse Sturm-Liouville problems

open access: yes, 2006
We introduce a variational algorithm, which solves the classical inverse Sturm-Liouville problem when two spectra are given. In contrast to other approaches, it recovers the potential as well as the boundary conditions without a priori knowledge of the ...

A novel dual‐decomposition method for non‐convex two‐stage stochastic mixed‐integer quadratically constrained quadratic problems

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

Integrated location–inventory planning for slow‐moving demands with waiting time limitations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...

Fixing disconnects: Exploring the emergence of principled adaptations in a competency‐based curriculum

open access: yesMedical Education, Volume 59, Issue 4, Page 428-438, April 2025.
Abstract Purpose Competency‐based medical education (CBME) promises to improve medical education through curricular reforms to support learner development. This intention may be at risk in the case of a Canadian approach to CBME called Competence by Design (CBD), since there have been negative impacts on residents. According to Joseph Schwab, teachers,

Development of HTS Current Leads for the ITER Project

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
The HTS current leads for the ITER project will be the largest ever operated, with unprecedented currents, up to 68 kA and voltages, up to 14 kV. According to the ITER agreement they will be provided in-kind by China.

Iterated deterministic substitution

open access: yesActa Informatica, 1977
Deterministic substitution of languages means substituting the same word (from a given language) for all occurrences of a symbol. For an arbitrary family $K$ of languages the notion of deterministic $K$-iteration grammar is introduced, which is essentially the iteration of a finite number of deterministic substitutions of languages from $K$.

A validity evaluation of lexicon‐based sentiment analysis of medical students' clinical performance from in‐training evaluation reports

open access: yesMedical Education, EarlyView.
Abstract Introduction Assessment of clinical performance has traditionally been a numbers game based upon Likert scale ratings. But, thanks to advances in the science of natural language processing (NLP), it is now possible to incorporate rich narrative data into assessment.

Comparing N versus Ne as divertor radiators in ASDEX-upgrade and ITER

open access: yesNuclear Materials and Energy, 2019
The study aims to estimate the influence of machine scale size on the behavior of plasma with extrinsic seeded impurities in the scrape-off layer (SOL) and divertor.

Progress in the ITER neutral beam test facility

open access: yesNuclear Fusion, 2019
Heating neutral beam (HNB) injectors, necessary to achieve burning conditions and to control plasma instabilities in ITER, are characterized by such demanding parameters that a neutral beam test facility (NBTF) dedicated to their development and ...
