The evaluation of network system effectiveness is the key method to judge whether the system network architecture is stable and effective. This paper adopts the entropy method and the experience of decision makers to establish the evaluation system of the network efficiency of the intelligent distribution network monitoring service system, basing on the evaluation index of network effectiveness obtained...
Chemotherapy was first used for the treatment of advanced lymphomas in the 1940s [1]. Since then several classes of chemotherapeutic compounds such as alkylating agents, antimetabolites, anthracyclines, plant alkaloids, and later topoisomerase inhibitors and taxanes have been identified or synthesized to treat various forms of cancer [2, 3]. Although numerous in vitro and animal studies have demonstrated...
The retrieval of visual cultural symbols is an important research field of inheriting and carrying forward Chinese traditional culture in digital way. Generally visual cultural symbols are foregrounds of natural images, so using shape features in image retrieval that needs image segmentation in advance has great advantages. At present, image segmentation is mostly interactive, which is quite subjective,...
This paper presents a glucose-responsive micro device capable of modulating drug diffusion rates according to changes in environmental glucose levels. New glucose-responsive composite membranes with enhanced mechanical strength were developed, in which chemically immobilized glucose oxidase and pH-responsive hydrogel nanoparticles were embedded within PDMS micro grids, functioning as intelligent ‘nano-valves’...
A drug-delivery microdevice integrating pH-responsive nano-hydrogel composite membranes functioning as intelligent nano valves is described. The polymeric microdevices are monolithic without requiring peripheral control hardware or additional components for controlling drug-release rates. pH-responsive nanoparticles were synthesized and embedded into a composite membrane. The resulting pH-responsive...
This paper presents the use of a monolithic, force-feedback MEMS (microelectomechanical systems) microgripper for characterizing both elastic and viscoelastic properties of highly deformable hydrogel microcapsules (15-25 mum) at wet state during micromanipulation. The single-chip microgripper integrates an electrothermal microactuator and two capacitive force sensors, one for contact detection (force...
This paper reports a monolithic, force-feedback MEMS (microelectomechanical systems) microgripper and its application to micro-scale compression testing of swollen hydrogel microcapsules during manipulation in an aqueous environment. The single-chip microgripper uses an electrothermal microactuator for grasping and integrates two capacitive force sensors, one for contact detection (force resolution:...
