Increasing penetration of renewable energy generation poses a challenge to power system inertia adequacy. It is vital provide long-term incentive signals induce mix with adequate supply. However, existing literature rarely studies mechanisms or considers constraints when making investment decisions. Thus, we propose an market quantify the value and remunerate provision. To examine impacts on mi...

The inertia of the power system currently lies in a relatively narrow range. However, increasing penetration distributed energy resources (DERs) will significantly reduce level, meanwhile its volatility. This affect system’s ability to contain maximum frequency excursion and recover from large disturbances. In order maintain security stability, common practice is incorporate constraints into un...

Antihypertensive drug treatment is based on stepped titration in response to elevated blood pressure (BP) measurements. However, measurements do not necessarily represent an individual’s true BP (due random error and biological variability), medications are always increased when above target (therapeutic inertia). We developed a Monte Carlo model with 10-year horizon investigate how measurement...

At the beginning of the 20th century the classical electron theory (or, perhaps more appropriately, the classical electromagnetic mass theory) the first physical theory that dared ask the question of what inertia and mass were was gaining momentum and there were hopes that physics would be finally able to explain their origin. It is argued in this paper that if that promising research path had ...

Dynamic behavior of a circular shaft with geometrical nonlinearity and constant spin, subjected to periodic axial load is investigated. The case of parametric combination resonance is studied. Extension of shaft center line is the source of nonlinearity. The shaft has gyroscopic effect and rotary inertia but shear deformation is neglected. The equations of motion are derived by extended Hamilto...

According to Einstein, General Relativity contains the essence of Mach’s ideas. Mach’s principle can be summarized by stating that the inertia of a body is determined by the rest of the mass-energy content of the universe. Inertia here arises from mass-energy there. The latter, was a statement made by John Wheeler in his 1995 book, Gravitation and Inertia, coauthored by Ciufolini. Einstein beli...

Teleoperation systems are expected to play an important role in daily healthcare and wellness applications. Time-delays typically cause stability and performance problems in these systems. As a remedy for such problems in position-error based bilateral teleoperations, a control algorithm is proposed which is derived as a robust modification of a Smith predictor structure for time-delay compensa...

A size-dependent Euler–Bernoulli beam model, which accounts for nonlocal stress field, strain gradient field and higher order inertia force field, is derived based on the nonlocal strain gradient theory considering velocity gradient effect. The governing equations and boundary conditions are derived both in dimensional and dimensionless form by employed the Hamilton principle. The analytical so...

It is well known that the reversibility of Stokes flow makes it difficult for small microorganisms to swim. Inertial effects break this reversibility, allowing new mechanisms propulsion and feeding. Therefore important understand unsteady fluid inertia on dynamics in flow. In work, we show how translate inertial non-motile organisms motile ones, from passive active particles. The method relies ...
