An Analysis of Nonlinear Differential Equations Describing the Dynamic Behavior of an Unbalanced Rotor

open access: yesEngineering Proceedings
The present paper investigates the dynamic behavior of an unbalanced rotor mounted in a balancing machine. Differential equations of motion are derived without linearization using Lagrange equations of the second kind to determine the nonlinear nature of

Dynamic diffusion load balancing [PDF]

open access: yes
We present the first analysis of a simple discrete diffusion scheme for dynamic load balancing. In each round (1-epsilon)n tasks are (arbitrarily) generated over a set of n processors, load is balanced amongst neighbours in some underlying graph, then a ...

The spring-and-lever balancing mechanism, George Carwardine and the anglepoise lamp. [PDF]

open access: yes, 2000
Two short and direct methods of exact analysis of the spring-and-lever balancing mechanism are presented. It is shown that perfect balance can be achieved by the use of a close-coiled spring whose free length is effectively zero and whose stiffness is ...

Locational-based Coupling of Electricity Markets: Benefits from Coordinating Unit Commitment and Balancing Markets

open access: yes, 2011
We formulate a series of stochastic models for committing and dispatching electric generators subject to transmission limits. The models are used to estimate the benefits of electricity locational marginal pricing (LMP) that arise from better ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Strong stability of Nash equilibria in load balancing games [PDF]

open access: yes
We study strong stability of Nash equilibria in the load balancing games of m (m >= 2) identical servers, in which every job chooses one of the m servers and each job wishes to minimize its cost, given by the workload of the server it chooses.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Research and development of new variable compression ratio (VCR) engine mechanism (2nd Report, Dynamics analysis and vibration experiment of VCR engine mechanism)

open access: yesNihon Kikai Gakkai ronbunshu, 2019
In order to improve the efficiency of combustion engines, variable compression ratio (VCR) engine is researched. VCR engine changes the compression ratio according to its mechanical configuration. One of the solutions to construct VCR engine is the multi-

The Balance for Balance

open access: yes
Sensory signals from the visual, vestibular, and proprioceptive systems are integrated based on their reliability to stabilize upright posture, in a process known as ‘sensory reweighting’. For example, when the sensory signals become noisy, the central nervous system decreases the reliance on such signals (down-weighting), while up-weighting ...
