In vivo fiber-optic confocal reflectance microscope with an injection-molded plastic miniature objective lens.
For in vivo optical diagnostic technologies to be distributed to the developed and developing worlds, optical imaging systems must be constructed of inexpensive components. We present a fiber-optic confocal reflectance microscope with a cost-effective injection-molded plastic miniature objective lens for in vivo imaging of human tissues in near real time. The measured lateral resolution is less...
متن کاملApplication of Soft Computing for the Prediction of Warpage of Plastic Injection Molded Parts
This paper deals with the development of accurate warpage prediction model for plastic injection molded parts using soft computing tools namely, artificial neural networks and support vector machines. For training, validating and testing of the warpage model, a number of MoldFlow (FE) analyses have been carried out using Taguchi’s orthogonal array in the design of experimental technique by cons...
متن کاملRNA chip: quality assessment of RNA by microchannel linear gel electrophoresis in injection-molded plastic chips.
Two major components of rRNA (18S and 28S rRNA) were separated by electrophoresis in injection-molded acrylic chips with a microchannel 100 microm in width, 40 microm in depth, and with 1 cm of separation distance. Microchannels were filled with 4 g/L hydroxypropylmethylcellulose as sieving polymer and 5 mg/L ethidium bromide for RNA staining. The fluorescent signals were detected by a fluoresc...
متن کاملWarpage Prediction in Plastic Injection Molded Part Using Artificial Neural Network
The main objective of this paper is to predict the warpage of a circular injection molded part based on different processing parameters. The selected part is used as spacers in automotive, transmission, and industrial power generation industries. The second goal is facilitating the setup of injection molding machine without (any) need for trial and error and reducing the setup time. To meet the...
متن کاملEstimation of lifetime for plastic gears
The importance of plastic gears for modern industry is growing every year. The engineer sizing plastic gears has a very difficult task. There is no international standard available for the strength analysis. The only method publicly accepted is the German guideline VDI2545. In addition to a lack of calculation methods there is a need for measuring material properties. This paper shall give an o...
