Interactive and Audience Adaptive Digital Signage Using Real-Time Computer Vision
No full textIn 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
ANALYSIS OF SLOVENE GAZELLE COMPANIES IN ACCORDANCE TO EMPLOYMENT AS WELL AS SOME INDICATORS OF PERFORMANCE
No full textPričujoče diplomsko delo obravnava gazele skozi izbrane dimenzije proučevanja – zaposlovanje, viri financiranja, dobičkonosnost in donosnost kapitala. Obravnavo smo, razdelili na dva dela. V prvem delu opredeljujemo gazele (dinamična podjetja), podajamo nekatere ključne informacije o gazelah, poudarjamo pomen tovrstnih podjetij za gospodarstvo ter navajamo pogoje za razvoj le-teh. V tem delu torej teoretično opredeljujemo problem in se na podlagi sekundarnih virov osredotočimo na dinamična podjetja skozi omenjene dimenzije proučevanja. Na podlagi sekundarne raziskave smo se seznanili z ozadjem problema in izpopolnili znanje o gazelah ter delovanju kot tudi vplivu teh na gospodarstvo. Empirična raziskava temelji na statistični populaciji 500 najhitreje rastočih podjetjih v Sloveniji v letu 2009. Lestvico teh podjetij je pripravila časopisna hiša Dnevnik, d. d. v sodelovanju z družbo Bisnode. Rezultati so pokazali, da so slovenska dinamična podjetja veliki zaposlovalci, predvsem podjetja v razredu MSP. Ta podjetja so tudi nadpovprečno poslovno uspešna in učinkovita v primerjavi s povprečjem vseh slovenskih podjetij. Ena izmed bolj presenetljivih ugotovitev pa je, da so ta podjetja v skladu z dosedanjimi raziskavami nekaterih slovenskih akademikov, v zadnjih letih hitro rast v večji meri, na račun lastniških, financirala z dolžniškimi viri.Present diploma thesis deals with gazelle companies in accordance to several chosen dimensions – employment, sources of finance, profitability and return on equity. We have separated the thesis into two consecutive parts. In the first part we define the “gazelle companies” (dynamic enterprises), we stress the importance of these companies and its influence on the state economy. We also indicate the conditions that must take place in order for these types of companies to successfully grow. In this first (theoretical) part we are presenting findings, gathered on the basis of the secondary research, through which we were able to comprehend the background of the issue. Empirical study focuses on 500 fastest growing companies in Slovenia in year 2009. The ranking is issued by Dnevnik, d. d. media company in cooperation with company named Bisnode. Results show that Slovene dynamic enterprises are significant job creators, especially the MSE companies. These companies are also very profitable and efficient (in terms of ROE). In addition, one of the most surprising findings throughout the thesis was the fact that gazelle companies have chosen non-ownership capital rather than ownership capital in order to finance their high growth strategies. Many academicians in recent years have already supported this assertion

Breadsticks from ‘Solina’ common wheat (Triticum aestivum) flour: Technological properties of flour and process optimization.
No full textSolina is a common wheat variety cultivated in mountain areas of central Italy (mainly in the Abruzzo region) because it is adapted to sustainable agriculture carried out in marginal areas with cold climates; therefore Solina-based products are of interest for consumers, territorial sustainment, and biodiversity conservation. Even though Solina is locally used for bread-making, due to its unique flavour, the poor gluten quantity and quality of its flours do not permit to produce high quality products.
Aim of this study was to evaluate the use of Solina flour to make breadsticks since, usually, low strength flours are used for this type of products. The low bread-making quality of Solina does not permit to use standard process parameters suitable for commercial wheat for its mixing process. Mixing parameters such as mixing speed-rate, oil, and water addition before mixing were thus modulated by using an experimental design in order to optimize the mixing process. The doughs were eventually leavened and baked to obtain breadsticks. Commercial wheat flour used for breadsticks production was used for making breadsticks used as control.
Baked breadsticks were analysed for their volume increase after leavening and baking, moisture, colour, texture and sensory properties. Solina breadsticks resulted more friable, crunchy and grain-flavoured than commercial common wheat used for breadsticks production. Moreover, high oil percentages and medium speed-rate were necessary in order to optimize these peculiar characteristics even though oil addition masked the typical grain-flavour of Solina flour. The use of water contents lower than the optimal hydration level enhanced the brown colour and the biscuit-like flavour of breadsticks even if these conditions reduced their crunchiness and friability..
This study confirms that the optimization of process parameters could permit to obtain high quality products even by using flours with low gluten content and quality provided that the qualitative characteristics of prime materials and the final product are known
Analysis and application of waste sludge from meat processing industry
No full textV 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
Where physically is the optical center?
No full textA simple and fast method of determining the position of the optical center without any specialized equipment is presented. The position of the optical center is a depth determining parameter in a panoramic depth imaging system [Peer, P., Solina, F., 2002. Panoramic depth imaging: single standard camera approach. Internat. J. Comput. Vision 47 (1/2/3), 149–160; Peer, P., Solina, F., 2005. Multiperspective panoramic depth imaging. In: Computer Vision and Robotics. Nova Science Publishers]. The reconstructed distances correspond well to the actual measured distances on the scene
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
No full textUvod: 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
UTILIZATION OF WASTE RUBBER FOR THE MANUFACTURE OF FREEZE/THAW RESISTING CONCRETE
No full textV diplomskem delu je predstavljena uporaba reciklirane gume pri proizvodnji betonov, ki so prav tako mrazoobstojni. Pri betonski mešanici smo kot nadomestek cementa uporabili elektrofiltrski pepel. V seriji vzorcev je bil uporabljen tudi aerant. Izvajali smo preizkuse tlačnih trdnosti betona, ter med seboj primerjali betonske vzorce brez dodatka aeranta in vzorce z dodatkom aeranta. Iste primerjave smo opravili tudi pri preizkusih mrazoobstojnosti otrdelih betonskih vzorcev. Uporaba reciklirane gume in elektrofiltrskega pepela je predstavljena tudi z vidika ponovne uporabe odpadnih meterialov.The thesis presents the use of recycled rubber in the manufacture of concrete, which are also freeze/thaw resistant. In concrete mixture fly ash was used as a substitute for cement . Air entraining admixture was also used in a series of samples. We carried out tests of compressive strength of concrete, and compared the concrete samples without addition of air entraining and samples with addition of air entraining admixture. The same comparisons was also carried out in tests of freeze/thaw on hardened concrete samples. The use of recycled rubber and fly ash is also presented in terms of re-used waste materials
