Discriminating ultrasonic proximity detection system

Enhancing Intrusion Detection System with proximity information

The wide spread of worms poses serious challenges to today’s Internet. Various IDSes (Intrusion Detection Systems) have been proposed to identify or prevent such spread. These IDSes can be largely classified as signature-based or anomaly-based ones depending on what type of knowledge the system knows. Signature-based IDSes are unable to detect the outbreak of new and unidentified worms when the...

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...

Bio-Inspired Ultrasonic System for Time of Flight Detection

The design and development of bio-inspired ultrasonic systems particularly that of some species of bats, has received the most attention due to the potential benefit of application in the field of biomedical engineering and robotics. In this paper an ultrasonic based device for the emulation of bat’s echo-location system, by means of piezo-polymer sensors and a neural network, capable to perfor...

An Ultrasonic System for Weed Detection in Cereal Crops

Site-specific weed management requires sensing of the actual weed infestation levels in agricultural fields to adapt the management accordingly. However, sophisticated sensor systems are not yet in wider practical use, since they are not easily available for the farmers and their handling as well as the management practice requires additional efforts. A new sensor-based weed detection method is...
