Research on Small Radius Curve Negotiation and Key Parameters of Tram
机车电传动, 2021 To research the small radius curve negotiation of the tram, the motion equation of a free wheelset passing through curve was firstly derived. In theoretically, the influence of the wheel-rail contact friction coefficient, the gauge distance and the curve

THE OPTIMAL SOLUTION OF THE LOB-PASS PROBLEM WITH KNOWN REACTION CURVES
Journal of the Operations Research Society of Japan, 1998 Summary: The ``lob-pass problem'' is a model which is used in the psychology. It describes the phenomena that the same choices decrease the effect, like the experience or the weariness. Abe and Takeuchi formulated it as an on-line learning problem, and pointed out that it is an extension of the multi-armed bandit problem.

Safety analysis of hydraulic anti-kink system on S curve passing of tram
机车电传动, 2022 Based on the principle of hydraulic anti-kink system, a four-module single vehicle type tram model with traditional wheelsets and a simplified dynamic model of the anti-kink system was established for the bending phenomenon caused by the single-type tram

On smooth curves passing through rational surface singularities
Mathematische Zeitschrift, 1995 Let \((X,C)\) be a pair where \(X\) is a germ of a normal two-dimensional singularity and \(C \subset X\) is a germ of smooth curve. Jaffe gave a complete description of such pairs up to isomorphisms when \(X\) is a rational double point in terms of the associated Dynkin diagram. In this paper that result is extended to a more general class of rational

Research on Passing Ability and Climbing Performance of Pipeline Plugging Robots in Curved Pipelines [PDF]
IEEE Access, 2020 To repair leaking pipelines for oil, natural gas and other dangerous media, a kind of pipeline sealing robot is proposed. The device is mainly divided into a robot drive unit, connection unit, and blocking unit. The robot drive unit is used to pull the blocking unit, allowing it to move in the pipeline.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.
