automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...
this paper demonstrates design and fabrication o f a mechatronic system for human drowsiness detection. this system can be used in multiple places. for example, in factories, it is used on some dangerous machinery and in cars in order t o prevent the operator o r driver from falling asleep. this system is composed of three parts: (1) mechanical, (2) electrical and (3) image processing system. a...
Background: Two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (uNGAL) in detection of acute kidney injury (AKI) in children have remained unanswered; first, which cut-off point of uNGAL has the highest value in detection of AKI; and second when is the best time for measuring this biomarker in a patient? Accordingly, the present study aimed to conduct a syst...
Tetanus is caused by the toxin secreted by Clostridium tetani. Due to the rapid infection with this bacterium, it is so important to investigate the tetanus immunity of people. Therefore, electrochemical biosensors, as one of the most effective tools in this regard, have demanded characteristics such as being fast, simple, cost-effective and portable. However, their detection sensitivity is not...
Optical property, such as spectral reflectance, bidirectional reflectance distribution functions and polarization characteristics of dried seaweeds is clarified together with an attempt for transparent foreign matter detection considering optical property of dried seaweeds, such as spectral transparency, bidirectional reflectance and transparency as well as polarimetric properties. Through expe...
