Purpose – Force output is extremely important for electromagnetic linear machines. The purpose of this study is to explore new permanent magnet (PM) array and winding patterns to increase the magnetic flux density and thus to improve the force output of electromagnetic tubular linear machines. Design/methodology/approach – Based on investigations on various PM patterns, a novel dual Halbach PM ...

This paper analyzes the design of a force-based impedance control for a haptic interface system characterized by a parallel kinematics. By exploiting the features of parallel mechanisms, which perform better than the serial ones in terms of dynamic performance, stiffness and position accuracy, and by implementing a closed-loop force control, the transparency of a haptic master system and the Žd...

Position and/or force feedback is critical in ensuring precise and safe operation of ionic polymer–metal composite (IPMC) actuators in io/micromanipulation. In this paper the design of an integrated sensory actuator is presented, where polyvinylidene fluoride (PVDF) films re used to provide simultaneous feedback of bending and force outputs of the IPMC actuator. The design adopts differential c...

This paper deals with electromagnetic design and 2-D (two-dimensional) magnetic field analysis of novel low force ripple linear switched reluctance (LSR) motor. The configuration that has been presented here has a higher number of rotor poles than stator poles, and the purpose of this configuration is to improve the force ripple, which is the weak point of LSRMs. In order to illustrate the ...

improvement in braking performance and vehicle stability can be achieved through the use of braking systems whose brake force distribution is variable. electronic braking force distribution has an important and serious role in the vehicle stopping distance and stability. in this paper a new approach will be presented to achieve the braking force distribution strategy for articulated vehicles. f...

In this paper we study the integration of various audio, visual and text-based descriptors for automatic video genre classification. Experimental validation is conducted on 26 video genres specific to web media platforms (e.g. blip.tv).

Data generated on location-aware social media provide rich information about the places (shopping malls, restaurants, cafés, etc) where citizens spend their time. That information can, in turn, be used to describe city neighborhoods in terms of the activity that takes place therein. For example, the data might reveal that citizens visit one neighborhood mainly for shopping, while another for it...

In recent years, tissue engineering with mechanical stimulation has received considerable attention. order to manipulate samples, there is a need for electromechanical devices, such as constant-force actuators, integrated deflection measurement. this paper, we present an electrostatic actuator allowing the generation of constant force and simultaneous displacement measurement intended character...

In this study, a novel triboelectric device is developed that consists of silicone-coated conductive yarn and PET film as active substances, an elastic spacer force controller. The prepared by applying thermally curable silicone to yarns using simple but continuous method. made 20 cm long can generate peak voltage high 225 V current outputs 2.4 µA. functions maintain the in separate state when ...
