In order to automate the scooping task, it is desirable that the resistive force acting on the bucket be obtained before the scooping is performed. The objective of this study is to derive theoretically the resistive forces acting on the bucket during scooping of piled rock fragments. First, the changes in the shape of the rock pile due to the penetration of it by the bucket are modeled. Based ...

Haptic interfaces are becoming more widely used in virtual reality simulations because of their enhancement to performance in training and simulation. Unintended vibration degrades the effectiveness of a haptic device and can reduce the user's ability to detect small details in the surface of simulated hard objects. Two important design factors for controlling haptic device vibrations are servo...

This work applies the contact formalism of classical mechanics and field theory, introduced by Herglotz later developed in context geometry, to describe electromagnetic systems with dissipation. In particular, we study an electron a non-perfect conductor variation cyclotron radiation. order apply system governed Lorentz force, it is necessary generalize gauge add term Lagrangian. We also k-cont...

Maximum elastance is an experimentally validated, load-independent systolic function index stemming from the time-varying elastance paradigm that decoupled extrinsic load from (intrinsic) contractility. Although Doppler echocardiography is the preferred method of diastolic function (DF) assessment, all echo-derived indexes are load dependent, and no invasive or noninvasive load-independent inde...

BiFeO3 based MIM structures with Ti-implanted Pt bottom electrodes and Au top electrodes have been fabricated on Sapphire substrates. The resulting metal-insulator-metal (MIM) structures show bipolar resistive switching without an electroforming process. It is evidenced that during the BiFeO3 thin film growth Ti diffuses into the BiFeO3 layer. The diffused Ti effectively traps and releases oxyg...

Metal-oxide-based resistive switching memory device has been studied intensively due to its potential to satisfy the requirements of next-generation memory devices. Active research has been done on the materials and device structures of resistive switching memory devices that meet the requirements of high density, fast switching speed, and reliable data storage. In this study, resistive switchi...

The swimming behavior of the nematode Caenorhabditis elegans is investigated in aqueous solutions of increasing viscosity. Detailed flow dynamics associated with the nematode’s swimming motion as well as propulsive force and power are obtained using particle tracking and velocimetry methods. We find that C. elegans delivers propulsive thrusts on the order of a few nanonewtons. Such findings are...

In this paper, we present an approach to study the behavior of compliant plates in granular media and optimize performance a robot that utilizes technique for mobility. From previous work fundamental tests on thin plate force generation inside media, introduce origami-inspired mechanism with non-linear compliance joints can be used propulsion. This concept one-sided joint limits create asymmetr...
