algorithm was applied to the two-dimensional non-guillotine rectangular packing problems. In this study, two different weight mechanisms in the PSO algorithm are used: fixed inertia weight and nonlinear varying inertia weight. The nonlinear varying inertia weights help to improve the speed of convergence and the search ability. In order to compare the performances of these weight mechanisms, a ...

THE NEUROBIOLOGICAL BASIS OF SLEEP INERTIA,1 WHICH REFERS TO THE COGNITIVE PERFORMANCE IMPAIRMENT, GROGGINESS AND TENDENCY TO RETURN TO SLEEP IMMEDIATELY AFTER AWAKENING2 IS UNKNOWN. Documented cognitive deficits due to sleep inertia include simple and complex reaction time, complex simulation, letter cancellation, logical reasoning, mental arithmetic, vigilance, and memory—in addition to confu...

When executing turning maneuvers, manual wheelchair users must overcome the rotational inertia of the wheelchair system. Differences in wheelchair rotational inertia can result in increases in torque required to maneuver, resulting in greater propulsion effort and stress on the shoulder joints. The inertias of various configurations of an ultralightweight wheelchair were measured using a rotati...

Introduction: In Planetary Science, thermal inertia has been defined the ability of a material to resist a temperature change when applying a periodic forcing function. Thermal inertia is used to answer scientific questions about the Martian surface and is used to constrain engineering requirements. However, one not familiar with its derivation, may inquire the following: 1) Why are the factors...

This article summarizes four formulations of the composite body method for the inertia matrix of a manipulator in the earlier works and presents a new formulation. These five formulations all use the first moments and the inertia tensors of composite bodies about the origin of the local frame. This paper also presents an algorithm for computing these first moments and inertia tensors. This algo...

Building on a formal theory of the structural aspects of organizational change initiated in Hannan, Pólos, and Carroll (2002a, 2002b), this paper focuses on structural inertia. We define inertia as a persistent organizational resistance to changing architectural features. We examine the evolutionary consequences of architectural inertia. The main theorem holds that selection favors architectura...

BACKGROUND Evidence suggests that patients with type 2 diabetes (T2DM) suffer from a high rate of "clinical inertia" or "recognition of the problem but failure to act." OBJECTIVE THE AIM OF THIS STUDY IS TO QUANTIFY THE RATE OF CLINICAL INERTIA BETWEEN TWO MODELS OF CARE: Pharmacist-Managed Diabetes Clinic (PMDC) vs. Usual Medical Care (UMC). METHODS Patients in a university based medical c...
