Bezpilotu mašīnu apmācība izmantojot stimulētās mācīšanās dziļos neirona tīklus koorporatīvās braukšanas sistēmā
2017
Šajā darbā ir izstrādāta programmatūra un demonstrēts, kā radiovadāmu mašīnu var apmācīt braukt trasē, izmantojot tikai video attēlus un neironu tīklus. Virtuālajā vidē tiek pierādīts, ka ar šādu metodi, apmācot transportlīdzkli braukt pa vienu trasi, tas spēj izbraukt kārdināli atšķirīgu trasi, ko modelis nav redzējis. Padziļināti tiek pētīti darbi par saistītajām tehnoloģijām, stimulēto mācīšanos un pozicionēšanas sistēmām, lai varētu turpināt darbu pie sistēmu, kas ļautu transportlīdzeklim pašam mācīties braukt. Šī darba mērķis ir izstrādāt programmatūru, kuru būtu iespējams izmantot uz reālas pašbraucošas mašīnas Mazda 6, kas ir pieejama, sadarbojoties ar EDI. Neironu tīkli un īpaši sti…
Electrochemical technology for the treatment of real washing machine effluent at pre-pilot plant scale by using active and non-active anodes
2018
Abstract Real effluent of washing machine is one of the major sources of microplastics and fabrics in municipal and surface water. The effluents constitute large volume of wastewater with different surfactants since every household and industries nowadays use washing machine rather than traditional hand washing. In this work, a real effluent of washing machine was treated by electrooxidation (EO) in a pre-pilot plant scale electrochemical flow reactor using active (Ti/Pt) or non-active (boron doped diamond (BDD)) anodes and Ti cathode. The effect of anode material (Ti/Pt or BDD) and the applied current density (16.6, 33.3 and 66.6 mA cm−2) on the decay of the organic matter, in terms of che…
Exploring the limits of anaerobic biodegradability of urban wastewater by AnMBR technology
2018
[EN] Anaerobic membrane bioreactors (AnMBRs) can achieve maximum energy recovery from urban wastewater (UWW) by converting influent COD into methane. The aim of this study was to assess the anaerobic biodegradability limits of urban wastewater with AnMBR technology by studying the possible degradation of the organic matter considered as non-biodegradable as observed in aerobic membrane bioreactors operated at very high sludge retention times. For this, the results obtained in an AnMBR pilot plant operated at very high SRT (140 days) treating sulfate-rich urban wastewater were compared with those previously obtained with the system operating at lower SRT (29 to 70 days). At 140 days SRT the …
Design of nutrient removal activated sludge systems
2003
A mechanistic mathematical model for nutrient and organic matter removal was used to describe the behavior of a nitrification denitrification enhanced biological phosphorus removal (NDEBPR) system. This model was implemented in a user-friendly software DESASS (design and simulation of activated sludge systems). A 484-L pilot plant was operated to verify the model results. The pilot plant was operated for three years over three different sludge ages. The validity of the model was confirmed with data from the pilot plant. Also, the utility of DESASS as a valuable tool for designing NDEBPR systems was confirmed.
Performance of a hybrid activated sludge/biofilm process for wastewater treatment in a cold climate region: Influence of operating conditions
2013
a b s t r a c t The main aim of the study was to investigate a hybrid MBBR process, mostly in terms of organic matter removal and nitrification, when operating with different values of the mixed liquor sludge retention time (SRT), and highlighting the influence of temperature on the process. Based on experience in practice it was hypothesized that nitrification could be maintained at far lower SRT's than in conventional activated sludge systems and with high organic loading rates applied. A field gathering campaign has been carried out on a hybrid activated sludge/biofilm. The obtained results highlighted that the pilot plant was capable to remove the organic matter at loading rates up to 3…
Expanded micro-particles by supercritical antisolvent precipitation: Interpretation of results
2008
Abstract Supercritical antisolvent (SAS) micronization has been used to obtain nanoparticles and micro-particles of several kinds of materials. Sometimes hollow expanded micro-particles have also been obtained. This work is focused on the analysis of this last morphology. We organized literature data and our previous experiments and we added new experiments on previously tested compounds and on compounds never tested before. As a result, expanded micro-particles using several compounds belonging to different categories and precipitated from different solvents in laboratory and pilot scale plants were obtained with diameters between about 10 and 180 μm. They also showed different sub-structu…
Natural organic matter coagulation in Valencia water supply. Pilot plant studies
1998
: To reduce disinfection by-product (DBP) formation in drinking water treatment, the presence of natural organic matter in surface waters must be minimised. This paper describes pilot plant studies carried out on two surface waters to assess the effectiveness of coagulation in organic matter removal, the Turia and Jucar rivers, which supply the city of Valencia (1m inhabitants). The experiments were conducted with different coagulants (iron sulphate, polyaluminium chloride (PACl)) and treatment schemes. Process effectiveness was evaluated in terms of effluent turbidity, presence of residual metal in final water, and organic matter removal. Four parameters were used to quantify organic matte…
Evaluation of a pilot-scale biotrickling filter as a VOC control technology for the plastic coating sector
2011
Abstract The performance and feasibility of a biotrickling filter (BTF) pilot unit for the treatment of exhaust gases from two robotic spray paint booths at a plastic coating facility were investigated. The volatile organic compound (VOC) concentrations in the emissions of the exhaust gases from the paint booths were relatively stable, although the VOC composition depended on the applied solvent-paint formulation in the booths. The pilot plant was operated for one year at empty bed residence times (EBRTs) ranging from 30 to 93 s. The performance of the system was affected by the solvent-paint formulations. An EBRT between 30 and 40 s was enough to meet legal requirements for products contai…
Electrochemical Syntheses Involving Carbon Dioxide
1990
The recent developments of electrosynthetic processes involving carbon dioxide are reviewed. Both processes involving carbon dioxide alone and electrocarboxylations are taken under consideration. The first of these two fields, mainly projected towards the production of basic chemicals such as methanol or carbon monoxide, is at present at a stage of fundamental research. Some interesting developments have recently appeared in the literature, concerning the use of electrode materials, or of transition metal complexes with particular catalytic activity. Electrocarboxylations are at a stage of more applicative development: some processes have reached the stage of pilot plant, and other have int…
El peligro como elemento vertebrador de los delitos contra la seguridad vial
2019
La presente tesis doctoral tiene por objeto el estudio del elemento del peligro como vertebrador de algunos delitos contra la seguridad vial, concretamente los recogidos en los artículos 379 a 382 del Capítulo IV del Título XVII del CP, que es además pieza diferencial de los ilícitos administrativos comprendidos en los artículos 75 y siguientes del RDL 6/2015. Los delitos contra la seguridad vial pueden ser definidos como el conjunto de infracciones, caracterizadas por la creación un riesgo para los bienes jurídicos de una doble tipología, difuso e individual. El primero de los peligros que tratan de conculcar es de lesión a la seguridad vial -anteriormente denominada seguridad del tráfico-…
