The aim of the present study was to determine the development of the inspiratory muscle fatigue in healthy human during incremental cycling to exhaustion under mild and heavy resistive loaded breathing in air and oxygen. Minute ventilation, tidal volume, respiratory rate, inspiratory mouth pressure, and parasternal EMG activities were recorded during an incremental cycling test under mild (12 c...

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 interaction of intruding objects with deformable materials arises in many contexts, including locomotion in fluids and loose media, impact and penetration problems, and geospace applications. Despite the complex constitutive behaviour of granular media, forces on arbitrarily shaped granular intruders are observed to obey surprisingly simple, yet empirical 'resistive force hypotheses'. The p...

Introduction: Non-linear resistive grids have been proposed 1,2 for image filtering and segmentation. In these implementations, smoothing of noisy data is obtained through the low pass filtering behavior of these resistive grids for small voltage differences between neighboring pixels. Two different methods are used to obtain segmentation with these resistive grids. One is to use so the called ...

OBJECTIVE To evaluate the effects of stretching and/or resistive exercise, followed by detraining, on the functional status of older people. METHODS Forty-five subjects were divided into four groups: control (CG; n=13; 66±6 years), stretching (SG; n=10; 69±6 years), resistive exercise (RG; n=13; 69±5 years), and resistive exercise and stretching (RSG; n=9; 66±5 years). The CG did not perform ...

We report on an analytical model which describes the bipolar resistive switching in electrochemical metallization cells. To simulate the resistive switching, we modeled the growth and dissolution of a metallic filament together with electron tunneling between the growing filament and the counter electrode. The model accounts for the controllability of the low resistive state and the RESET curre...

We investigated the bipolar resistive switching characteristics of the resistive random access memory (RRAM) device with amorphous carbon layer. Applying a forming voltage, the amorphous carbon layer was carbonized to form a conjugation double bond conductive filament. We proposed a hydrogen redox model to clarify the resistive switch mechanism of high/low resistance states (HRS/LRS) in carbon ...

In order to automate the scooping task, it is necessary to obtain the resistive forces acting on the bucket before the scooping is performed. In this study, empirical equations to predict the friction coefficient between the bucket and rocks, the friction coefficient among rocks and particle diameters were obtained by using the resistive forces which are measured at the beginning of the scoopin...
