An optimization model of EMU circulation problem for high-speed railway [PDF]

open access: yesAIP Conference Proceedings, 2017
The electronic multiple unit (EMU) circulation plan schedule EMUs to perform train tasks based on a timetable while satisfying a number of constraints. This paper propose a model considering several constraints such as maintenance capability, accommodation capacity and maintenance management modes.

Social Reciprocity [PDF]

open access: yes
We define social reciprocity as the act of demonstrating one's disapproval, at some personal cost, for the violation of widely-held norms (e.g., don't free ride).

Development of Permanent Magnetic Traction Motors for High-speed EMUs

open access: yes机车电传动, 2016
High-speed EMUs were strict with the performance and reliability, such as efficiency and power density, while traditional asynchronous traction motors had little room for improvement of performances to meet the requirements of new generation high speed ...

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

open access: yesAdvanced Science, EarlyView.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...

Recursive Online Enumeration of All Minimal Unsatisfiable Subsets

open access: yes, 2018
In various areas of computer science, we deal with a set of constraints to be satisfied. If the constraints cannot be satisfied simultaneously, it is desirable to identify the core problems among them. Such cores are called minimal unsatisfiable subsets (
