Interactive and Audience Adaptive Digital Signage Using Real-Time Computer Vision
Full text linkIn this paper we present the development of an interactive, content‐aware and cost‐effective digital signage system. Using a monocular camera installed within the frame of a digital signage display, we employ real‐time computer vision algorithms to extract temporal, spatial and demographic features of the observers, which are further used for observer‐specific broadcasting of digital signage content. The number of observers is obtained by the Viola and Jones face detection algorithm, whilst facial images are registered using multi‐view Active Appearance Models. The distance of the observers from the system is estimated from the interpupillary distance of registered faces. Demographic features, including gender and age group, are determined using SVM classifiers to achieve individual observer‐specific selection and adaption of the digital signage broadcasting content. The developed system was evaluated at the laboratory study level and in a field study performed for audience measurement research. Comparison of our monocular localization module with the Kinect stereo‐system reveals a comparable level of accuracy. The facial characterization module is evaluated on the FERET database with 95% accuracy for gender classification and 92% for age group. Finally, the field study demonstrates the applicability of the developed system in real‐life environments

Razmerje med reliefom in geološko strukturo v porečju reke Solina
No full textIn this paper, within the framework of morphostructural features, relationship between relief and geological structure in the river basin of Solina (north-eastern Bosnia and Herzegovina) is analyzed. Main goal of this study is to investigate causal relationship between complex geological characteristics of the terrain and genesis, morphological evolution and differentiation of three relief units in the river basin of Solina. Relief of river basin of Solina is predominantly non-conformal, tectonically predisposed; its structure is dominated by Cretaceous - Paleogene clastites. In this paper are applied modern geomorphological-geological methods, field work, analysis of topographic and geological maps, as well as satellite images of the studied area. Presentation of data has been realized in the Geographic Information System, and the geospatial data were geo-visualized on two thematic maps.V tem članku so v okviru morfostrukturnih značilnosti analizirani odnosi med reliefom in geološko strukturo v porečju reke Solina (severovzhodna Bosna in Hercegovina). Glavni cilj te študije je raziskati vzročno razmerje med kompleksnimi geološkimi značilnostmi terena in genezo, morfološko evolucijo in diferenciacijo treh reliefnih enot v porečju reke Solina. Relief porečja reke Solina je večinoma nekonformen, tektonsko predisponiran; njegovo strukturo prevladujejo kredno-paleogenski klastiti. V tem članku so uporabljene sodobne geomorfološko-geološke metode, terensko delo, analiza topografskih in geoloških kart ter satelitskih slik preučevanega območja. Predstavitev podatkov je bila realizirana v Geografskem informacijskem sistemu, geoprostorski podatki pa so bili geovizualizirani na dveh tematskih kartah
Analysis and application of waste sludge from meat processing industry
Full text linkV magistrskem delu smo raziskovali možnosti trajnostne uporabe odpadnega blata, ki nastaja v mesnopredelovalni industriji. Namen našega dela je preučiti alternativne metode ravnanja z odpadnim blatom, s posebnim poudarkom na procesu torefikacije, ki omogoča izboljšanje kurilne vrednosti in zmanjšanje vsebnosti vlage v materialu.
V teoretičnem delu smo opisali delovanje čistilne naprave, iz katere smo pridobili vzorce, in proces torefikacije. Eksperimentalni del je vključeval termično obdelavo vzorcev pri različnih temperaturah in analizo njihovih fizikalnih ter kemijskih lastnosti. Ugotovili smo, da torefikacija znatno povečuje kurilno vrednost obeh vzorcev, "Sito" in "Flotat", pri čemer je toreficirano sito pri 350 °C doseglo najvišjo vrednost, toreficiran flotat pa pri 300 °C. Ugotovili smo tudi, da so toreficirani vzorci sita imeli višji masni delež fiksnega ogljika, medtem ko so toreficirani vzorci flotata imeli višji masni delež pepela, kar pojasni zakaj je imelo nižjo kurilno vrednost kot tudi razmerje goriv. Vsi dokazi strmijo k temu, da so toreficirani vzorci sita bolj primerni za kurjenje in za proizvodnjo energije kot toreficirani vzorci flotata. Glede adsorpcijskih sposobnosti pa smo ugotovili, da je material neprimeren za adsorpcijo fosfata, ker vzorci že vsebujejo fosfatne spojine, medtem ko je za adsorpcijo bakra je primeren. Iz vseh dobljenih rezultatov lahko z gotovostjo trdimo, da kot material za gorivo ter kot adsorbent za razne snovi, je sito toreficirano pri 350 °C, najbolj primerno za uporabo. Za flotat pa je najbolj primeren, ko je toreficiran pri 300 °C.
Rezultati so pokazali, da toreficirano blato predstavlja obetaven vir energije in učinkovit adsorbent za onesnaževala, kot je baker. Raziskava prispeva k razvoju trajnostnih praks v mesnopredelovalni industriji in odpira možnosti za nadaljnje raziskave o uporabi odpadnega blata v različnih aplikacijah. S tem delom smo potrdili, da je učinkovito ravnanje z odpadnim blatom ključno za zmanjšanje okoljskega vpliva in povečanje energetske učinkovitosti.In our master\u27s thesis, we explored the possibilities for the sustainable use of waste sludge generated in the meat processing industry. The aim of our work was to investigate alternative methods for managing waste sludge, with a particular focus on the torrefaction process, which enhances the calorific value and reduces the moisture content of the material.
In the theoretical part, we described the operation of the wastewater treatment plant from which we obtained samples, and the torrefaction process. The experimental part involved the thermal treatment of samples at various temperatures and the analysis of their physical and chemical properties. We found that torrefaction significantly increased the calorific value of both samples, "Sito" and "Flotat," with torrefied Sito reaching the highest value at 350°C and torrefied Flotat at 300°C. We also found that the torrefied samples of sito had a higher mass fraction of fixed carbon, while the torrefied samples of flotat had a higher mass fraction of ash. This explains why flotat had a lower calorific value as well as a lower fuel ratio. All evidence points to the fact that torrefied sito samples are more suitable for combustion and energy production compared to torrefied flotat samples. Regarding adsorption capabilities, we determined that the material is unsuitable for phosphate adsorption because the samples already contain phosphate compounds. However, it is suitable for copper adsorption. Based on all the results obtained, we can confidently conclude that as a fuel material and as an adsorbent for various substances, sito torrefied at 350°C is the most suitable for use. For flotat, the most suitable torrefaction temperature is 300°C.
The results showed that torrefied sludge represents a promising energy source and an effective adsorbent for pollutants such as copper. Our research contributes to the development of sustainable practices in the meat processing industry and opens up possibilities for further research on the use of waste sludge in various applications. With this work, we confirmed that efficient waste sludge management is crucial for reducing environmental impact and increasing energy efficiency

Carbon footprint modeling of methylated melamine resin
Full text linkPodnebne spremembe in globalno segrevanje sodita med glavne probleme na svetu, zato države in podjetja stremijo k temu, da bi preprečila ali vsaj zmanjšala vzroke teh pojavov. Eden izmed načinov za dosego tega cilja je zmanjšanje emisij toplogrednih plinov v industriji, zato smo v diplomskem delu v sodelovanju s podjetjem Melamin iz Kočevja razvili model za ocenjevanje ogljičnega odtisa za produkt metilirano melaminsko smolo heksametoksimetilol melamin. Za osnovo smo uporabili metodologijo ISCC+ in v izračun vključili emisije toplogrednih plinov, ki nastajajo pri transportu kemikalij in proizvodnji produkta in ne za celotni življenjski cikel izdelka. Za to metodologijo smo se odločili zaradi pobude podjetja Melamin. Za transport smo ugotovili, da je iz vidika ogljičnega odtisa najbolj ugodno, da se na kopnem kemikalije prevažajo z železniškim transportom namesto s cestnim in preko morij z ladijskim prevozom namesto letalskim. Pri proizvodnji produkta smo ugotovili, da je za zmanjšanje ogljičnega odtisa potrebno kemikalije, pridobljene iz fosilnih virov, zamenjati s kemikalijami, pridobljenimi iz bioosnovanih virov. Primerjali smo metanol na osnovi fosilnih virov z biometanolom iz podjetij BioMCN in Sodra. Količina nastalih emisij v proizvodnji z uporabo metanola na osnovi fosilnih virov je bila 3,88 tCO2eq/tprod. Če smo uporabili biometanol iz podjetja BioMCN, se je ogljični odtis zmanjša na 3,40 tCO2eq/tprod, medtem ko so z biometanolom podjetja Sodra bile emisije še nižje in sicer 3,05 tCO2eq/tprod. Pomembno je tudi, da se vsaj del porabljene elektrike proizvaja iz nefosilnih virov, kot je denimo lesna biomasa, saj se s tem zelo zmanjša ogljični odtis. Podjetje pridobiva 25 % električne energije iz lesne biomase in s tem zmanjša ogljični odtis zaradi porabe elektrike za 22,14 % v primerjavi s celotnim odjemom iz omrežja.Climate change and global warming are two of the most important issues facing the world. Therefore, countries and companies are trying to prevent or at least reduce the negative consequences of these phenomena. One way is to reduce greenhouse gas emissions in industry. Therefore, in this thesis, in cooperation with the company Melamin from Kočevje, we have developed a model for estimating the carbon footprint for the product methylated melamine resin hexamethoxymethylol melamine. We used the ISCC+ method as a basis and included emissions from the transport of chemicals and product manufacturing in the calculation and not for the entire lifecycle of the product. We decided on this methodology due to the initiative of the company Melamin. As far as transport is concerned, we have established that, in terms of the carbon footprint, it is most advantageous for chemicals to be transported overland by rail rather than by road, and over the sea by ship rather than by plane. In the production of the product, it was found that in order to reduce the carbon footprint, it is necessary to replace chemicals obtained from fossil sources with chemicals derived from bio-based sources. We compared methanol based on fossil sources with biomethanol from two companies, BioMCN and Sodra. The amount of emissions generated by the use of methanol based on fossil sources is 3,88 tCO2eq/tprod. Using biomethanol from BioMCN, the carbon footprint would be reduced to 3,4 tCO2eq/tprod , and using biomethanol from Sodra, the carbon footprint would be even lower at 3,05 tCO2eq/tprod. It is also important that at least some of the electricity consumed is generated from non-fossil sources such as wood biomass, as this significantly reduces the carbon footprint. The company obtains 25 % of its electricity from wood biomass, reducing the carbon footprint from electricity consumption by 22,14 % compared to purchasing all energy from the grid
Exploration of the Genetic Diversity of Solina Wheat and Its Implication for Grain Quality
No full textDifferent Solina wheat accessions (n = 24) collected in the Abruzzo region (Italy) were studied using 45,000 SNP markers generated from the DarTseq platform. The structure of genetic data was analyzed by Principal Component Analysis and Hierarchical Cluster analysis that revealed the existence of two main clusters (Clu1 and Clu2) characterized by samples with different geographical origin. The Solina genetic dataset was further merged and analyzed with a public genetic one provided by CIMMYT containing 25,963 genotypes from all over the world. The Solina accessions occupied a vast space, thus confirming a high heterogeneity of this landrace that, nevertheless, is considerably unique and placed quite far from other clusters. Clu1 and Clu2 divergence were clearly visible. Solina clusters were genetically closer to landraces from Turkey and the central fertile crescent than to the Italian genotypes present in the dataset. Selected commercial quality traits of accessions of the two Solina clusters were analyzed (yield, thousand kernel weight, test weight, and protein content), and significant differences were found between clusters. The results of this investigation did not highlight any relationships of Solina with Italian genotypes, and confirmed its wide genetic diversity by permitting to identify two genetic groups with distinct origin and quality traits
Drug use and quality of life in adolescents
Full text linkUvod: Kakovost življenja je dimenzija, ki ni omejena zgolj na posameznikove finančne zmožnosti, temveč na občutek zadovoljstva v lastnem življenju. V življenju obstajajo obdobja, v katerih je človek bolj ranljiv in dovzeten za uporabo prepovedanih drog. To so vsakdanje težave zaradi stanovanja, službe, družine, prijateljev ali obremenjujoče osebne izkušnje iz otroštva, in pubertete ter pritiski, s katerimi se srečujejo otroci v šoli. Namen zaključnega dela je bil na osnovi pregleda literature raziskati, kakšna je kakovost življenja pri mladostniku, ki uživa droge.Introduction: Quality of life is a dimension that is not limited to an individual\u27s financial capacity, but rather to the sense of satisfaction in one\u27s own life. There are periods in life when a person is more vulnerable and susceptible to illicit drug use. These are the everyday problems of housing, work, family, friends, the burdensome personal experiences of childhood and adolescence, and the pressures faced by children at school. The aim of the thesis was to investigate, based on a literature review, the quality of life of adolescents who use drugs
