This paper presents a control system based on linear quadratic state feedback and state estimation for an hydraulic actuator with a exible mechanical load The purpose of the control system is to improve the dynamic properties by reducing the oscillatory behavior of the load and to eliminate the steady state error in the load position caused by external disturbances Using a simpli ed linear mode...

This paper describes a middleware architecture for distributed automotive systems that supports dynamic load balancing of tasks. Load balancing could be applied if an external device is added to the vehicle. The middleware architecture has to deal with the fusion of such non-built-in devices. An important factor to set up such a system is the identification of the requirements that should be ha...

The directed transport of an overdamped Brownian motor moving in a spatially periodic potential that lacks reflection symmetry (i.e. a ratchet potential) is studied when driven by thermal and dichotomic nonequilibrium noise in the presence of an external, constant load force. We consider both, the classical and the quantum tunneling assisted regimes. The current-load characteristics are investi...

Mechanical loading is believed to be a critical factor in the development and treatment of knee osteoarthritis. However, the contact forces to which the knee articular surfaces are subjected during daily activities cannot be measured clinically. Thus, the ability to predict internal knee contact forces accurately using external measures (i.e., external knee loads and muscle electromyographic [E...

The bacterial flagellar motor of Escherichia coli is a nanoscale rotary engine essential for bacterial propulsion. Studies on the power output of single motors rely on the measurement of motor torque and rotation under external load. Here, we investigate the use of magnetic tweezers, which in principle allow the application and active control of a calibrated load torque, to study single flagell...

In our work we consider applications which generate queries w.r.t. many different knowledge bases. We presuppose that for a particular KB there exists many possible query servers. In order to successfully build applications that exploit these KB servers, an appropriate middleware is required. In particular, if there are many servers for a specific KB, the middleware is responsible for managing ...

1. Abstract A 2-dimensional lumbar spine is modeled with 64 back muscles and the static behavior of the model is predicted using an optimization technique. The goal of this study was to investigate if a follower load can be produced by the back muscles for enhancing the mechanical stability of the lumbar spine in a quiet standing posture. Recent studies demonstrated that the stability of the lu...
