Tabular GANs for Uneven Distribution

GANs are well known for success in the realistic image gen-eration. However, they can be applied in tabular data generation as well.We will review and examine some recent papers about tabular GANs inaction. We will generate data to make train distribution bring closer tothe test. Then compare model performance trained on the initial traindataset, with trained on the train with GAN generated data, also wetrain the model by sampling train by adversarial training. We show thatusing GAN might be an option in case of uneven data distribution be-tween train and test data

Improving PM Collection of EPA Other Test Method (OTM) 36 Precutter

The Environmental Protection Agency (EPA) regulates the amount of particulate matter (PM) emitted by different industrial processes to protect human health and the environment. EPA Test Method 5 is the standard method to determine PM emissions from stationary sources. However, moisture present in emission sources can yield overestimated PM concentrations when using EPA Method 5. Alternatively, EPA Other Test Method (OTM) 36 regulates the method used for determining the concentration of PM2.5 emissions, which are particles with a diameter of less than 2.5 micrometers, from moisture-saturated stationary source gas streams. The EPA has found that the OTM 36 sampling train measures lower PM concentrations than actual concentrations in the emission source. This is because the sampling train’s precutter nozzle, which is the first instrument of a sampling train placed into an emission source, collects particles at smaller sizes than intended, preventing these particles from being measured by the sampling train. The purpose of this research is to create a new precutter nozzle design that allows the PM sampling train to more accurately measure PM to reflect actual concentrations in emission sources tested by OTM 36. By using computational fluid dynamics (CFD) simulations in ANSYS Fluent program, the collection efficiency of different dimensions of the new precutter nozzle was calculated to choose the best design that more accurately collects PM. Based on this objective, a precutter nozzle with a 7-degree half-cone angle and 3-cm throat length was chosen as the most viable design.

Analysis of air pollutants presents in a bricks factory at Carabayllo district, Lima

The aim of the study was analyzing pollutants such as: sulfur dioxide, nitrogen dioxide, carbon monoxide and hydrogen sulfide; as well as PM10, which they were expelled by the brick Factory "Cuadros " located in the town of San Pedro de Carabayllo , Lima, Peru . Analyses were made for gases by sampling train and for PM10 was taken by Hi-Vol. Analyzed the results do not exceed Environmental Quality Standards. The Wind direction predominate in SSW ( South South West) and Wind speed indicate that moderate is.

Effect of Liquid Inhibitor De-dioTM on Dioxin-Furan Emission From Medical Waste Incineration Plant

The aim of the study was to investigate the effects of liquid inhibitor (known as De-dioTM) on the emission of dioxin-furan from medical waste incineration plants. Various concentrations of De-dioTM solutions were tested on the medical waste incinerator combustion chamber with an injection flow rate of 1.5 L/min. The sampling protocol of US EPA Method 23 was adopted to collect the sample using a modified US EPA Method 5 sampling train. The flue gas emission was collected before and during the injection of the chemical. The result showed that the De-dioTM was able to reduce or minimize the formation of dioxin-furan to meet its regulatory limits. The study illustrates that the higher the concentration of De-dioTM solution, the lower the dioxin-furan emission was observed in the flue gas.
