BACKGROUND Osteoarthritis affecting the first metatarsophalangeal joint of the foot is a common condition which results in pain, stiffness and impaired ambulation. Footwear modifications and foot orthoses are widely used in clinical practice to treat this condition, but their effectiveness has not been rigorously evaluated. This article describes the design of a randomised trial comparing the e...

Background Footwear with a curved sole profile remains popular and there is evidence of its effects on gait and posture [1,2]. Existing literature describes how different styles of roll over footwear affect gait, although the effects of the precise radii of the curve of the sole on the gait rocker function and other reported effects have not been investigated. The aim of this study was to relat...

A state estimator design is presented for a Mars rover prototype. Odometry estimates are obtained by utilizing the f u l l kinematics of the vehicle including the nonlinear internal kinematics of the rover rocker-bogey mechanism as well as the contact kinematics between the wheels and the ground. Additional sewing using gyroscopes, acclerometers and visual sensors allows for robust rover motion...

The driving range of an electric vehicle can be increased through efficient integration the large battery within structure. In this regard, a divided rocker concept from existing study is investigated, in which into two parts by means division plane. One part remains sided and enables attachment surrounding structures, while other functionally integrated side frame housing. scope paper, several...

The ubiquitous garbage pollution in lakes, wetlands and rivers has become an urgent problem to be solved. With Arduino as the core, this paper completed function design, circuit design program design. control system of small water cleaning robot is designed, whole remote module divided into module, rocker wireless module. part uses Nano series microprocessor. On basis, signal transmitted receiv...

‎Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$‎. ‎Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$‎. ‎We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$‎, ‎$bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$‎. ‎I...
