We study a framework where two duopolists compete repeatedly in prices and where chosen prices potentially affect future market shares, but certainly do not affect current sales. This assumption of consumer inertia causes (noncooperative) coordination on high prices only to be possible as an equilibrium for low values of the discount factor. In particular, high discount factors increase opportu...

balance, breakdown of balance, and generation of inertia–gravity waves in vortical flows are fundamental topics of prime importance in geophysical fluid dynamics. this research aims to find the optimum balance relation as well as the rossby-number variation of the spontaneous generation of inertia–gravity waves in a baroclinic, two-layer, boussinesq model on a doubly-periodic f-plane geometry f...

a fluid, which is stable under the action of buoyancy, can oscillate under the influence of buoyancy and coriolis forces. the resulting ageostrophic oscillations with a frequency between coriolis and buoyancy frequencies are called inertia-gravity waves, hereafter igws. in this study we investigate the generation and propagation of igws over iran. to this end, the weather research and forecasti...

This paper presents a comparison of two methods to represent variable blade inertia in codes for aero-servo-elastic simulations wind turbines: the nonlinear aeroelastic multi-body model HAWC2 and geometrically exact beam BeamDyn OpenFAST. The main goal is enable these tools simulate dynamic behavior turbine with inertia. However, current state-of-the-art load simulation turbines cannot inertia,...

‎In our paper [A‎. ‎B‎. ‎M‎. ‎Basheer and J‎. ‎Moori‎, ‎On a group of the form $2^{10}{:}(U_{5}(2){:}2)$] we calculated the inertia factors‎, ‎Fischer matrices and the ordinary character table of the split‎ ‎extension $ 2^{10}{:}(U_{5}(2){:}2)$ by means of Clifford-Fischer‎ ‎Theory‎. ‎The second inertia factor group of $2^{10}{:}(U_{5}(2){:}2)$‎ ‎is a group of the form $2_{-}^{1+6}{:}((3^{1+2}{...

Experimental examination of the gyroscopic and rotary inertia effects on the chatter boundary in a milling operation is the chief aim of this article. The equations of motion of the tool vibration are derived based on Timoshenko beam theory and Hamilton principle by considering gyroscopic moment, rotary inertia, velocity-dependent process damping and radial immersion effect. For a range of dept...

OBJECTIVES We investigated whether a lack of inertia force of late systolic aortic flow and/or apical asynergy provoke early diastolic dysfunction in patients with coronary artery disease (CAD). BACKGROUND Left ventricular (LV) isolated diastolic dysfunction is a well-recognized cause of heart failure. METHODS We evaluated LV apical wall motion and obtained left ventricular ejection fractio...

Limited research has been done on exoskeletons to enable faster movements of the lower extremities. An exoskeleton’s mechanism can actually hinder agility by adding weight, inertia and friction to the legs; compensating inertia through control is particularly difficult due to instability issues. The added inertia will reduce the natural frequency of the legs, probably leading to lower step freq...

Since Thorstein Veblen, perennial themes in institutionalist writings have included the role of imitation (or emulation) and the tension between inertia (or conservatism) and innovation in individual and organizational behavior. Prior models of organizational behavior have examined two search processes that represent this tension. One is local search, in which an organization restricts experime...
