The simplest model possible for bouncing systems consists of a point mass bouncing passively on a mass-less spring without viscous losses. This type of spring-mass model has been used to describe the stance period of symmetric running gaits. In this study, we investigated the interaction between horse and rider at trot using three models of force-driven spring (-damper)-mass systems. The first ...

This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time to maintain fast update rates for haptic controls. In addition, they prohibit direct connection of haptic interfaces. Penalty methods, which employ spring-damper models for cal...

In his new commentary, Damper re-emphasises his claim that parity is not a generalisation problem. But when proper account is taken of the arguments he puts forward, we nd that the proposed conclusion is not the only one that can be drawn. In adding the word`still' to the title of his ongoing commentary, Damper re-emphasises his claim that`parity is not a generalisation problem.' His view is th...

Eksilti, yazılı ve sözlü anlatımda bazı dil birimlerini, yine o dilin kuralları çerçevesinde derin yapıda bırakan bir olayıdır.

This research paper represents the analysis and simulation of semi-active suspension using non-linear modeling Magneto-Rheological (MR) with consideration hysteresis behavior for a quarter car model. The is based on assumption that each wheel experiences same disturbance excitation. Hysteresis analyzed Bingham, Dahl's, Bouc-Wen models. focuses passive, Dahl, models five road profiles. desired d...

In this paper, we describe the design and manufacturing of a viscous inertial mass-damper (VIMD) prototype. The damper parameters, mass, damping coefficient can be continuously adjusted. Experimental validations were carried out on VIMD with various parameters scaled sagged cable 19.47 m long for vibration mitigation, along simulation study using finite element method (FEM). experimental result...

Propeller-induced longitudinal vibration resonance in marine propulsion shafting systems causes great harm to the hull structure and is primary source of shipboard noise. Integrating a friction damper with designed parameters into thrust bearings can prevent these issues. To investigate performance damper-integrated bearing transmission control, an experimental theoretical study carried out lab...

This article reviews the popular reasons for the belief that dwarf elliptical galaxies and (ordinary) elliptical galaxies are distinct and separate species. They include: light–profile shape (or similarly image concentration); the magnitude–central surface brightness diagram; the magnitude–effective surface brightness diagram (or similarly the magnitude–effective radius diagram); and the Fundam...

This letter presents a miniaturized probe-fed elliptical microstrip patch antenna (PF-EMPA) targeting the 8.50-10.55 GHz band for radiolocation applications. The proposed design is composed of an elliptical patch inserted into an elliptical slot. In order to achieve our goals and control the impedance matching, we adjusted the offset distance from the elliptical patch to the side of the ellipti...
