OBJECTIVES To determine socioeconomic inequalities in frequent knee pain (FKP), knee osteoarthritis (OA), and associated health-related quality of life (HRQoL) in Sweden. METHOD In 2007 a postal questionnaire about knee pain was sent to a random sample of 10 000 residents of Malmö, Sweden (7402 individuals responded). Subjects reporting pain with duration ≥ 4 weeks in one or both knees in the...

This paper presents a simulation framework for evolution on uneven terrains for a wheeled mobile robot such as a synchronous drive robot. The framework lends itself as a tool capable of solving various problems, such as forward kinematic based evolution, inverse kinematic based evolution, path planning and trajectory tracking. This framework becomes particularly useful when we understand that t...

Today, Robotic is an essential technology from the entertainment to the industry. Thousands of articles have been published on Robotic. There are various types of robots such as parallel robots, industrial robots, mobile robots, autonomous mobile robots, health-care robots, military robots, entertainment robots, nano robots and swarm robots. So, this variety brings a lot of problems in Robotic....

In general, identification and verification are done by passwords, pin number, etc., which are easily cracked by others. To overcome this issue, biometrics has been introduced as a unique tool to authenticate an individual person. Biometric is a quantity which consists of individual physical characteristics that provide more authentication and security than the password, pin number, etc. Nevert...

This paper addresses the posture control problem for robotic systems subject to kinematic constraints. The key idea is to consider the kinematic constraints of the mechanisms from their structure equations, instead of Artigo submetido em 10/03/2011 (Id.: 01293) Revisado em 27/05/2011 Aceito sob recomendação do Editor Associado Prof. Carlos Roberto Minussi explicitly using the constraint equatio...

Les faux kystes du pancréas (FKP) se développent chez environ 2% des patients présentant une pancréatite aigüe. Ils peuvent évoluer vers la régression spontanée ou se compliquer d'une hémorragie, de compression ou de rupture. Le drainage spontané des FKP dans un viscère creux (duodénum, estomac, ou colon) reste un mode d'évolution exceptionnel. Nous rapportant le cas d'une patiente âgée de 74 a...

Introduction we aimed to introduce a 6-universal-prismatic-spherical (UPS) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. We proposed a strategy to provide a fast and accurate solution to the kinematic problem. The proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...

in recent years, biodiesel has been considered as a good alternative of diesel fuels. density and viscosity are two important properties of these fuels. in this study, density and kinematic viscosity of biodiesel-diesel blends were estimated by using artificial neural network (ann). a three-layer feed forward neural network with levenberg-marquard (lm) algorithm was used for learning empirical ...
