The use of machine learning to identify the correctness of HS Code for the customs import declarations
No full textAs an increasing volume of international trade activities around the world, the amount of cross-boarder import declarations grows rapidly, resulting in an unprecedented scale of potentially fraudulent transactions, in particular false commodity code (e.g., HS Code). The incorrect HS Code will cause duty risk and adversely impact the revenue collection. Physical investigation by the customs administrations is impractical due to the substantial quantity of declarations. This paper provides an automatic approach by harnessing the power of machine learning techniques to relief the burden of customs targeting officers. We introduced a novel model based on the off-the-shelf embedding encoder to identify the correctness of HS Code without any human effort. Determining whether the HS Code is correctly matched with commodity description is a classification task, so the labelled data is typically required. However, the lack of gold standard labelled data sets in customs domain limits the development of supervised-based approach. Our model is developed by the unsupervised mechanism and trained on the unlabelled historical declaration records, which is robust and able to be smoothly adapted by the different customs administrations. Rather than typically classifying whether the HS Code is correct or not, our model predicts the score to indicate the degree of the HS Code being correct. We have evaluated our proposed model on the ground-truth data set provided by Dutch customs officers. Results show promising performance of 71% overall accuracy.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
Flavored waters: influence of ingredients on antioxidant capacity and terpenoid profile by HS-SPME/GC-MS
No full textThe antioxidant profiles of 39 water samples (29 flavored waters based on 10 natural waters) and 6 flavors used in
their formulation (furnished by producers) were determined. Total phenol and flavonoid contents, reducing power, and DPPH
radical scavenging activity were the optical techniques implemented and included in the referred profile. Flavor extracts were
analyzed by HS-SPME/GC-MS to obtain the qualitative and quantitative profiles of the volatile fraction of essential oils. Results
pointed out a higher reducing power (0.14 11.8 mg of gallic acid/L) and radical scavenging activity (0.29 211.5 mg Trolox/L) of
flavored waters compared with the corresponding natural ones, an interesting fact concerning human health. Bioactive compounds,
such as polyphenols, were present in all samples (0.5 359 mg of gallic acid/L), whereas flavonoids were not present either in
flavored waters or in flavors. The major components of flavor extracts were monoterpenes, such as citral, R-limonene, carveol, and
R-terpineol
HS-stability and complex products in involution semigroups
No full textWhen does the complex product of a given number of subsets of a group generate the same subgroup as their union? We answer this question in a more general form by introducing HS-stability and characterising the HS-stable involution subsemigroup generated by a subset of a given involution semigroup. We study HS-stability for the special cases of regular ∗-semigroups and commutative involution semigroups.</p
Removal of humic substances from water using solar irradiation and granular activated carbon adsorption
No full textFor the existing water treatment processes, difficulties in removing humic substances (HS) to improve drinking water quality, and safety, have created the
demand for exploring novel options to enhance HS removal. Here a combination of solar irradiation and granular activated carbon (GAC) adsorption is proposed. It aims to make use of the most freely available and abundant
energy source, sunlight, to improve the performance of GAC adsorption process.
An investigation into how characteristics of HS vary under natural sunlight and how this influences the subsequent removal of HS by GAC adsorption was carried
out. Bulk water parameters, and more specifically, UV absorbance at 254 nm
(UV254), as well as dissolved organic carbon (DOC) were used in conjunction with molecular weight (MW) to evaluate the performance of the solar-GAC method.
The observation was made that solar irradiation led to a decrease in DOC, UV254 and MW of HS. The high MW components were photodegraded into smaller
molecules, even with very low solar intensity in winter. Significant photodegradation of small molecules was also achievable by exposure to natural
sunlight alone. Pre-treatment using solar irradiation was shown to successfully improve the GAC adsorption performance on HS removal, increasing the DOC
removal from 69 % to 95 %. An up to three-fold increase in the adsorption
capacity of GAC for the irradiated HS was observed. Solar collectors were
found to effectively enhance the photodegradation of HS, and consequently
enhance the removal of HS by GAC adsorption. The application of solar
collectors could be a viable option for humic water treatment. The proposed
solar irradiation-GAC adsorption method provides a new approach for the
treatment of humic rich waters. The utilization of solar irradiation in water
treatment processes is considered a sustainable and promising field
Comparison of Molecular Markers to Detect Fresh Sewage in Environmental Waters
No full textHuman-specific Bacteroides HF183 (HS-HF183), human-specific E. faecium esp (HS-esp), human-specific adenoviruses (HS-AVs) and human-specific polyomaviruses (HS-PVs) assays were evaluated in freshwater, seawater and distilled water to detect fresh sewage. The sewage spiked water samples were also tested for the concentrations of traditional fecal indicators (i.e., E coli, enterococci and Clostridium perfringens) and enteric viruses such as enteroviruses (EVs), sapoviruses (SVs), and torquetenoviruses (TVs). The overall host-specificity of the HS-HF183 marker to differentiate between humans and other animals was 98%. However, the HS-esp, HS-AVs and HS-PVs showed 100% host-specificity. All the humans-specific markers showed > 97% sensitivity to detect human fecal pollution. E. coli, enterococci and, C. perfringens were detected up to dilutions of sewage 10−5, 10−4 and 10−3 respectively. HS-esp, HS-AVs, HS-PVs, SVs and TVs were detected up to dilution of sewage 10−4 whilist EVs were detected up to dilution 10−5. The ability of the HS-HF183 marker to detect fresh sewage was 3 to 4 orders of magnitude higher than that of the HS-esp and viral markers. The ability to detect fresh sewage in freshwater, seawater and distilled water matrices were similar for human-specific bacterial and viral marker. Based on our data, it appears that human-specific molecular markers are sensitive measures of fresh sewage pollution, and the HS-HF183 marker appears to be the most sensitive among these markers in terms of detecting fresh sewage. However, the presence of the HS-HF183 marker in environmental waters may not necessarily indicate the presence of enteric viruses due to their high abundance in sewage compared to enteric viruses. More research is required on the persistency of these markers in environmental water samples in relation to traditional fecal indicators and enteric pathogens
Hydrochemistry of sulphide-bearing waters in La Rioja
No full textIn this work are studied the hydrochemical characteristics of the sulphide-bearing waters originating from springs and boreholes in La Rioja. These water points are located mainly in the Weald facies materials, especially in the Oncala Group limestones, also in the limestone facies of the Urbion and Enciso Croups. These waters have their origin in groundwater, flows through the Weald facies, that are behaved as a means of low-mean permeability. Sulphide-bearing waters belongs to calcium-sulphate and high salinity facies; the pH is basic, Eh Slightly reducing, contents in H2S and HS; among 3 and 74 mg/ I. Sulphate^-reduction with presence of organic matter seems to be the most common origin of the H2S and HS' dissolve

Yritysesittelyvideo Hs-Vesi Oy:lle
No full textOpinnäytetyöni on yritysvideo HS-Vesi Oy:lle joka toimii Hämeenlinnan, Akaan ja Hattulan kun- nan kunnallisena vesihuolto yhtiönä. Kuvasin, editoin ja värimäärittelin videon. Videon käsikirjoitus ja kuvausten organisointi tapahtui yhteistyössä yrityksen kanssa.
Tavoitteeni työssä on tutkia mahdollisuuksia jälkikäsittelyssä. Tulen perehtymään värimäärittelyyn sekä käytettyyn kameraan ja kuvaustekniikkaan. Tavoitteenani oli kuvata kaikki materiaali raaka formaatissa, mutta tämän kaltaisessa videossa ja valmistumis prosessi tuli vastaan ongelmia, jotka käänsivät mielipiteeni tästä
Suurin osa työstäni tulee olemaan kuvausta, leikkausta ja värimäärittelyä. Eniten aion painottua värimäärittelyyn. Unohtamatta kuitenkaan kuvausta koko prosessista sen alusta aina loppuun asti valmiin videon yritykselle palautukseen asti.
Isoin tavoite jonka itselleni olen asettanut, on oppia enemmän värimäärittelystä ja sen eri työkaluista ja termeistä.Avainsanat: multimedia, Internet, video, journalismiSubject of this thesis is corporate video for water management company called Hs-Vesi Oy. Com- pany manages waters for cities of Hämeenlinna, Akaa and Hattula. For the video i did the filming, editing and color correction. Screenwriting and organizing of video filming were done in collabora- tion with the ccompany.
The purpose for this thesis were to study different possibilities of color correction. I will be empha- sized to color correction, to the camera that were used and techiques of filming video. In the begin- ning of this project my goal was to film all material in raw format, but as it will reveal, that in this kind of video, there came problems on the way that changed my opinion about this.
Most of my thesis will deal with filming, editing and color correcting of the video. I will also cover the hole process of this video, from the very beginnig till the end, when i gave final product to the company.
Biggest goal for me was to learn more about color correction and possibilities that lies in it. Also to learn how to use tools and understand the terminology.Työtä koskeva video löytää Hs-Vesi Oy:n internet sivuilta
