1	Měření a vyhodnocení produkce emisních plynů ve vybraném provozu s chovem skotu, návrhy na jejich snižování a hodnocení zásad "Správné zemědělské praxe" KOLÁŘ, Kamil January 2016 (has links) Measurement and evaluation of exhaust gas production in the cattle selected operation, proposals reduction and evaluation principles of "Good Agricultural Practice". This master's thesis is focused on the issue of air pollution and also on the individual components of the environment, laws and legislation related to this subject and measured elements of microclimate that we can consider stable. The aim of this master's thesis is to measure emissions of carbon dioxide, nitrous oxide, ammonia and methane in the selected operation. The measurement was carried out at farm Skalka Lipí on cattle for milk production. Photoacustic INNOVA 1412 multi-gas distributor was used like measure device. This thesis also deals the best available techniques leads to the reduction of exhaust gas production.
2	Photonics-based Multi-gas Sensor Matharoo, Inderdeep 14 December 2011 (has links) The design of a photonics-based multi-gas sensor is presented. Absorption spectroscopy theory has been analyzed to derive key requirements for effective gas concentration measurements. HITRAN spectral analyses have determined appropriate ranges for single and multi-gas sensing. A discussion of two setups (large-scale setup and portable prototype) outlines relevant results for the development of innovative data processing algorithms (floating-point technique (FPT)). Eight absorption lines were experimentally detected (761 nm range), facilitating the recognition of oxygen spectra with surety. The FPT was used to measure oxygen concentration with an approx. 2.5% error when scanning one absorption line. Strategies to reduce the error to below 0.1% and to improve the prototype are presented. The sensor is expected to operate in an inhomogeneous network. The network utilizes different sensors capable of cross-using information to achieve high reliability and accuracy, in order to predict, prevent, and recognize man-made and natural threats. photonics optical gas sensor inhomogeneous network multi-gas data processing absorption spectroscopy HITRAN oxygen reliability accuracy 0799 0752 0537 0544 0548 0771
