AERODYNAMIC DISTURBANCE ON VEHICLE’S DYNAMIC PARAMETERS [PDF]

open access: yesJournal of Engineering Science and Technology, 2018
This research paper analysed the influence of aerodynamic disturbance on vehicle’s dynamic parameters. The vehicle dynamics were formulated from the Newton’s Second Law for modelling the vehicle.

Load Parameter Identification for Parallel Robot Manipulator Based on Extended Kalman Filter

open access: yesComplexity, 2020
Load is the main external disturbance of a parallel robot manipulator. This disturbance will cause dynamic coupling among different degrees of freedom and make heaps of model-based control methods difficult to apply.

The pitch-heave dynamics of transportation vehicles [PDF]

open access: yes, 1975
The analysis and design of suspensions for vehicles of finite length using pitch-heave models is presented. Dynamic models for the finite length vehicle include the spatial distribution of the guideway input disturbance over the vehicle length, as well ...

Online coherency identification and stability condition for large interconnected power systems using an unsupervised data mining technique [PDF]

open access: yes, 2019
Identification of coherent generators and the determination of the stability system condition in large interconnected power system is one of the key steps to carry out different control system strategies to avoid a partial or complete blackout of a power

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

The influence of disturbance location and intensity on the deformation and failure of deep roadway surrounding rocks

open access: yesFrontiers in Materials
The surrounding rocks in deep roadways frequently undergo dynamic disturbances caused by adjacent blasting or mining activities. These dynamic disturbances lead to the propagation and coalescence of cracks in the surrounding rock, inducing dynamic ...

COLD-SAT dynamic model [PDF]

open access: yes
This report discusses the development and underlying mathematics of a rigid-body computer model of a proposed cryogenic on-orbit liquid depot storage, acquisition, and transfer spacecraft (COLD-SAT). This model, referred to in this report as the COLD-SAT

Modeling and supervisory control design for a combined cycle power plant [PDF]

open access: yes, 2012
The traditional control strategy based on PID controllers may be unsatisfactory when dealing with processes with large time delay and constraints. This paper presents a supervisory model based constrained predictive controller (MPC) for a combined cycle ...

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Time-Varying Characteristics of Granite Microstructures after Cyclic Dynamic Disturbance Using Nuclear Magnetic Resonance

open access: yesCrystals, 2017
To investigate the variation in the characteristics of rock microstructure after cyclic dynamic disturbances, a split Hopkinson pressure bar (SHPB) was used to carry out cyclic dynamic impact tests on granite, and the P-wave velocity was used as the ...
