The presence of an elevated amount methane (CH4) in exhaled breath can be used as a non-invasive tool to monitor certain health conditions. A compact, inexpensive and transportable CH4 sensor is thus very interesting for this purpose. In addition, if the also able simultaneously measure carbon dioxide (CO2), one extract end-tidal concentration CH4. Here, we report on such based commercial detection module using tunable diode laser absorption spectroscopy. It was found that measured CH4/CO2...
Wastewater treatment plants significantly contribute to greenhouse gas emissions, including nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). Current methods measure these emissions typically target specific molecular compounds, providing limited scope potentially incomplete profiles. Here, we show an innovative ultra-broadband coherent open-path spectroscopy (COPS) system capable of simultaneously monitoring multiple gases. This novel approach combines Fourier transform with a...
Due to the broad-spectrum and high-efficiency antibacterial activity, antimicrobial peptides (AMPs) their functions have been studied in field of drug discovery. Using biological experiments detect AMPs corresponding activities require a high cost, whereas computational technologies do so for much less. Currently, most methods solve identification as two independent tasks, which ignore relationship between them. Therefore, combination sharing patterns tasks is crucial problem that needs be...
Abstract Mosquitos, sometimes carrying deadly diseases such as malaria, zika, and dengue fever, cause much concern. To control mosquitos, it is important to effectively monitor their presence behavioral trends. We have constructed two optical sensing systems for insects based on light attenuation backscattering, respectively. The systems, which were tested with the potentially dangerous Aedes albopictus Culex pipiens, able extract wing-beat frequency, when they passed impinging light,...
Insects constitute a very important part of the global ecosystem and include pollinators, disease vectors, agricultural pests, all with pivotal influence on society. Monitoring control such insects has high priority, automatic systems are highly desirable. While capture analysis by biologists gold standard in insect identification, optical laser techniques have potential for high-speed detection identification based shape, spectroscopic properties as reflectance fluorescence, well wing-beat...
Abstract Numerous natural materials are porous, contain free gas and scattering light strongly. Scattering brings about a strong trapping of an associated prolonged transit time for photons through medium. In contrast to the matrix materials, enclosures require very narrowband laser radiation probing. We have in present study used media absorption spectroscopy method oxygen thin (cm) samples utilizing tunable diode laser, while pulsed dye was employed corresponding measurements on larger...
Ultra-broadband spectroscopy in the mid-infrared (MIR) wavelength range, where most molecular species have strong, distinct absorption features, has a great potential for gas sensing applications. Novel MIR supercontinuum (SC) sources excel their ability to provide broadband light together with high spatial coherence. Using this unique combination of properties, we recently demonstrated SC tailor-made Fourier Transform Spectrometer (FTS) and multipass cell multispecies trace detection [1]....
Faster-than-Nyquist (FTN) techniques offer a transmission rate beyond that of Nyquist criterion without imposing bandwidth expansion. On the other hand, orthogonality among modulated pulse shapes can be destroyed because FTN signaling, whereupon inter-symbol interference (ISI) appears, and hence an irreducible error floor occurs. This paper presents optimal pilot design for channel estimation in signaling transmissions. By taking advantage additional cyclic prefix, resultant ISI imposed by...
Acute rhinosinusitis is a common infectious disease, which, in more than 90% of cases, caused by viruses rather bacteria. Even so, antibiotics are often unnecessarily prescribed, and the long run this contributes to alarming level resistance. The reason that there no good guiding tools for defining background infection. One main factor clearance infection if non-obstructed ventilation from sinus nasal cavity. Gas Scattering Media Absorption Spectroscopy (GASMAS) has potential diagnosing...
We describe a simple approach to enhance vision, which is impaired by close range obscuring and/or scattering structures. Such structures may be found on dirty windscreen of car, or tree branches blocking the vision objects behind. The main idea spatially modulate obscuration, either periodically moving detector/eye letting obscuration itself, such as swinging in wind. has similarities electronic lock-in techniques, where feature interest modulated enable it isolated from strong perturbing...
