Small Methane Detection System using Optical Spectrum Characteristics

Three dimensional photoacoustic imaging of vascular anatomy in small animals using an optical detection system

A 3D photoacoustic imaging instrument for characterising small animal models of human disease processes has been developed. The system comprises an OPO excitation source and a backward-mode planar ultrasound imaging head based upon a Fabry Perot polymer film sensing interferometer (FPI). The mirrors of the latter are transparent between 590 – 1200nm but highly reflective between 1500-1600nm. Th...

Are Optical Gas Imaging Technologies Effective For Methane Leak Detection?

Concerns over mitigating methane leakage from the natural gas system have become ever more prominent in recent years. Recently, the U.S. Environmental Protection Agency proposed regulations requiring use of optical gas imaging (OGI) technologies to identify and repair leaks. In this work, we develop an open-source predictive model to accurately simulate the most common OGI technology, passive i...

Robot control system using SMR signals detection

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

طراحی و امکان سنجی ساخت fluorescence detection system برای دستگاهpcr

در این پروژه هدف طراحی و ساخت fluorescence detection systemجهت آشکارسازی مولکول های dna می باشد. در روش pcr، طی چندین چرخه دمایی، مولکول های dna کپی می شوند و سپس با استفاده از روش fluorescence detection، مولکول های بر انگیخته شده dna آشکارسازی می شوند. پس از آشکارسازی می توان به کپی و یا عدم کپی dnaها پی برد.می توان برای جداسازی مولکول های dna بر اساس طولشان، از روش gel electrophoresis استفاده...
