This study developed an enhanced adaptive self-organizing fuzzy slidingmode controller (EASFSC) for robotic systems. Rather than using the output error and the error change of the system, the EASFSC uses a sliding surface and its differential as the input variables of a fuzzy logic controller (FLC) in a self-organizing fuzzy controller (SOFC) to generate a control input through fuzzy operation....

A comparison of performance of three different types of graphene biosensors for the detection of prostate specific antigen was reported. Three different graphene structures were synthesized by mechanical exfoliation, microfluidic and self assembly respectively, representing graphene composites from pure to hybrid. Various parameters of different types of graphene biosensors were compared, such ...

We present experimental observations of self-trapped rings carrying zero topological charge, along with simulations that display the self-focusing dynamics of the rings and their stability features in materials with saturable nonlinearities.

The thermal and mechanical stability of self-assembled MOEMS components consisting of 3D mirrors have been evaluated. The thermal–mechanical constants of the hinge material (AZ4562 photoresist) used to power the surface tension self-assembly process have been measured and used to predict the stability of assemblies. The Young’s moduli and thermal expansion coefficients showed constant values of...

Cyclic molecules provide better stability for their aggregates. Typically in nature, the unique cyclic cell membrane lipids allow thermophilic archaea to inhabit extreme conditions. By mimicking the biological design, the robustness of self-assembled synthetic nanostructures is expected to be improved. Here we report topology effects by cyclized polymeric amphiphiles against their linear counte...

Health status measures in rheumatoid arthritis that have been extensively validated for use in clinical trials are generally used also in correlative studies, e.g. to predict future health status. This application requires stability (repeatability of measurements). The purpose of our study was to determine the stability of commonly used health status measures. Two measurements at an interval of...
