In recent years, the Rotating electromagnetic Field Eddy Current (RFEC) testing technique has attracted widespread attention due to its various advantages for the inspection of tubular structures. However, most of the related work were focused on the detection of inner wall defects on metal pipes using feed-through probes, which are often not applicable for outer wall defect detection. This work proposed an encircling RFEC technique and demonstrated its feasibility on the detection of outer wall defects. First, the basic principle of the encircling RFEC technique is introduced. Three-dimensional Finite Element (FE) model was built in COMSOL to analyze the distribution of the rotating electromagnetic field and study the interaction between the defects and eddy currents. The axial component of the resultant magnetic field due to defect was selected as a characteristic signal and obtained from the FE models to study the factors, including pipe tilt, defect circumferential location, defect orientation and defect size, that influence the detection performance. An Encircling RFEC system using a probe with six excitation windings and a single bobbin pick-up coil was constructed and used to inspect a steel pipe with one axial and one circumferential defect. The obtained voltage signal due to defect can form a Lissajous pattern in the impedance plane and can be used for defect evaluation. The results showed that the proposed encircling RFEC technique is capable of detecting outer wall defects of both orientations, and determining the circumferential location of the defect.

Rečni transport materiala je proces, ki je stalno prisoten v vodotokih. Prisotnost tega procesa je posledica energije vodnega toka, pa tudi erozije, ki predstavlja vir materiala, ki se premešča v vodotokih. Prisotnost plavin v vodotoku vpliva na spreminjanje njegovih lastnosti in oblike, njihove posledice se na primer kažejo v spremembah rečne struge in pokrajine ter zapolnjevanju akumulacijskih pregrad. Poznavanje količin transporta materiala v vodotoku ima tako pomembno vlogo pri razumevanju naravnih procesov v vodotoku. V diplomski nalogi obravnavamo dinamiko premeščanja sedimentov v hudournikih na območju Save Dolinke. Na podlagi zapolnjenosti in projektnih volumnov zaplavnih pregrad na hudourniških pritokih Save Dolinke skušamo oceniti količine materiala, ki se premeščajo v strugah teh hudournikov. S pomočjo primerjave lastnosti prispevnih območij vodotokov s premeščanjem sedimentov v njih skušamo ugotoviti kateri dejavniki imajo največji vpliv na količino transporta sedimentov v strugah hudournikov. Cilj diplomske naloge je nadgraditi razumevanje dinamike transporta sedimentov in določiti bilance transporta sedimentov za posamezne pritoke Save Dolinke, ter ugotoviti kateri dejavniki imajo na transport sedimentov največji vpliv. Na podlagi analize v diplomski nalogi je ocenjeno, da se v strugah hudourniških vodotokov na območju Save Dolinke letno povprečno premesti 547 m3 rinjenih plavin oziroma 2,15 m3 rinjenih plavin na hektar prispevnega območja. Po ugotovitvah diplomske naloge imajo na transport sedimentov najizrazitejši vpliv lastnosti padavin in njihova erozivnost, ter pokrovnost tal. River transport of material is a process that is constantly present in watercourses. Its presence is due to the energy of the water flow, as well as erosion. The presence of sediments in the watercourse changes its characteristics and shape, which can be seen in changes of the riverbed and landscape. Knowledge about the amount of sediment transport in a watercourse has an important role in understanding its natural processes. In the graduation thesis, we discuss the dynamics of sediment transport in torrents located in Sava Dolinka river catchment. Based on the volume of retained sediments and design volumes of check dams, we try to estimate the quantities of material that is transported by these torrents. By comparing the properties of watercourses’ drainage catchments with the transport of sediments in them, we try to determine which factors impact the rate of sediment transport. The aim of the graduation thesis is to improve the understanding of sediment transport dynamics and to determine transport rates for individual torrents, as well as investigation which factors have the greatest impact on the sediment transport. Based on the analysis conducted in the scope of the thesis, it is estimated, that an average of 547 m3 of sediments or 2,15 m3/ha of catchment area are transported annually in the torrents located in this territory. The erosivity of the precipitation and soil cover are indicated as two most dominant factors.

Inovacije so že od nekdaj gonilna sila napredka gospodarstva in civilizacije. Najpogosteje se inovacije povezujejo z raziskovalno-razvojnimi aktivnostmi pri izdelkih. Konkurenčne prednosti evropskih podjetij pa ne izhajajo zgolj iz inovacij izdelkov, temelječih na R&R delu, ampak tudi iz ne-tehniških oziroma organizacijskih inovacij, s katerimi želimo posodobiti proizvodne procese. Pri tem je zelo pomemben parameter, ki ga v doktorski disertaciji imenujemo inovacijska učinkovitost. Inovacijska učinkovitost proizvodnih podjetij je sposobnost, da z implementacijo večjega števila tehniških ali organizacijskih inovacij, kot posledic izbranih dejavnikov za povečanje inovacijske učinkovitosti, povečujejo svojo sposobnost za razvoj novih izdelkov in s tem tudi svojo donosnost. Namen disertacije je bil raziskati vpliv dejavnikov za povečanje inovacijske učinkovitosti v proizvodnih podjetjih. V ta namen je bil razvit model vplivnih dejavnikov za povečanje inovacijske učinkovitosti proizvodnih podjetij. Cilj doktorske disertacije je bil, glede na razviti model, ugotoviti vpliv medsebojnih povezav posameznih sklopov dejavnikov za povečanje inovacijske učinkovitosti proizvodnih podjetij, ugotoviti njihov vpliv na tehniške in organizacijske inovacije ter njihov neposredni vpliv na sposobnost razvoja in uvedbe novih izdelkov na trg in donosnost podjetja. Doktorska disertacija je omejena na podatke, ki smo jih pridobili s pomočjo ankete Raziskava proizvodne dejavnosti v Evropi (EMS). Naše analize so bile opravljene z naprednimi statističnimi metodami. Pregled literature je pokazal, da inovacije niso dovolj raziskane, še posebej to velja za merjenje organizacijskih inovacij. Raziskave so pokazale, da proizvodna podjetja, ki so pogosteje sposobna uporabljati inovacijske koncepte na srednjem ali celo visokem nivoju, praktično ne proizvajajo enostavnih izdelkov. V skupini šestih identificiranih vplivnih dejavnikov za povečanje inovacijske učinkovitosti obstajata dva, ki močno vplivata na razvoj novih izdelkov in njihovo lansiranje na trg. To sta subjekt sodelovanja (sodelovanje s kupci) in R&R aktivnosti. Obstajajo trije tehnični in kar sedem organizacijskih konceptov, izmed katerih večina močno vpliva na sposobnost razvoja in lansiranja novih izdelkov na trg. Innovation has always been known to be the driving force of progress in the economy and civilization. Mostlly innovations are associated with research and developement activities of products. Competitive advantages of European companies do not only arise from innovations of products based on R & D work, but also from non-technical or organizational innovations, whose intent is to update production processes. In this context, there is a very important parameter called »Innovation efficiency« in this dissertation. Innovation efficiency of manufacturing companies is ability of implementing a larger number of technical or organizational innovations as a result of selected factors to increase their inovations efficiency, increasing their capability to develop new products and therefor their profitability. The aim of the dissertation was to investigate the influence of factors for increasing innovation efficiency in production companies. For this purpose, a model of influenting factors for increasing the innovation efficiency of manufactoring companies was developed. The goal of dissertation was, according to this model, to determine the influence of connections in between of individual sets of factors in order to increase the innovation efficiency of production companies, their impact on technical and organizational innovations and their direct impact on new products and on the profitability of the company. The doctoral dissertation is limited to the data obtained by the European Manufacturing Survey (EMS). Research carried out with advanced statistical methods. A literature review has shown innovations aren´t sufficiently explored, especially for measuring organizational innovations. Researces have shown production companies, that are more often capabile to use inovation concepts on medium or even on high level, practicaly do not produce simple products. Among six identified influential factors to increase inovation efficiency there are two, which has high influence on developement of new products and their launch on market. They are subject cooperation (cooperation with buyers/customers) and R&D activities. There are three technical and even seven organizational concepts, and majority of them have strong influence on capability of developement and lounching new products on market.

Diplomsko delo raziskuje in prikazuje, kako lahko različni dejavniki vplivajo na posredovanje resnice v politično dokumentarnih filmih skozi različna časovna obdobja in kraje. Po ogledu politično dokumentarnega filma se analizirajo vsi dejavniki, ki lahko nezavedno in zavedno vplivajo na sporočilo filma. Eden izmed teh dejavnikov je produkcija, ki lahko z velikostjo produkcijske ekipe, količine vloženega denarja in zastopanju velikih produkcijskih hiš, spremenijo smer pogleda na film. Diploma examines and illustrates how different factors influence the transmission of truths in political documentaries through different time periods in places. After viewing the political documentary film, all factors are analyzed which can unconsciously and knowingly influence the film's message. One of these factors is production, which can, with the size of the production team, increase the amount of money invested in representing large production houses, changing the direction of the film.

Analizirali smo poškodovanost bukovih gozdov v Sloveniji zaradi snega. V analizo smo vključili 22.609 oddelkov na bukovih rastiščih, na katerih je bil delež bukve vsaj 10 % celotne lesne zaloge sestojev. Količino, strukturo in pogostnost poškodb sestojev zaradi snega smo primerjali s poškodbami bukovih gozdov zaradi vetra in žleda. Največji delež v sanitarnem poseku so imeli vetrolomi, nato snegolomi, takoj zatem žledolomi. Pri snegolomih in vetrolomih je praviloma delež poškodovanih dreves iglavcev precej višji, pri žledolomih pa sta bila deleža listavcev in iglavcev skoraj enaka. V bukovih gozdovih je zaradi snega najbolj poškodovano drevje mlajših in srednjedobnih razvojnih faz. Izmed preučevanih treh klimatskih, štirih sestojnih in petih rastiščnih spremenljivk so bili v model binarne logistične regresije pojavljanja snegolomov vključene količina snega v spomladanskih mesecih (marec, april, maj), fitoregija, skalnatost, naklon terena in matična podlaga. Verjetnost za poškodovanost bukve zaradi snega se povečuje s povečevanjem količine zapadlega snega v spomladanskih mesecih, s povečevanjem naklona terena in z zmanjševanjem skalnatosti. V primerjavi z alpskim območjem je verjetnost poškodb pri enaki količini snega na območju preddinarskih gozdov za 4,2-krat, na območju dinarskih za 3,4-krat in na območju predalpskih bukovih gozdov za 1,9-krat večja. V bukovih gozdovih je bukev manj dovzetna za poškodbe zaradi snega kot smreka, zato lahko razloge za relativno visok sanitarni posek v bukovih gozdovih delno razložimo s spremenjenostjo gozdov zaradi primesi iglavcev. Sneg v bukovih gozdovih v največji meri poškoduje drevje mlajših in srednjedobnih razvojnih faz, zato so z vidika stabilnosti ustreznejša pogostejša redčenja nižjih jakosti. The aim of our study was to analyse snow damage in beech stands in Slovenia. 22.609 compartments with at least 10 % of European beech (Fagus sylvatica) in the total growing stock were included in the research. Amount, structure and frequency of snow breakages in beech forests were compared to damage due to other disturbance agents, namely wind and ice, while factors influencing the occurrence of snow damage were analysed in the second part of the study. The largest share in the sanitary felling accounted to windthrows, followed by snow and ice damage. Conifers were relatively more damaged compared to deciduous species by snow and wind, yet their proportions in ice damage were similar. The majority of damage occured in trees of younger and middle-aged developmental stages. Three climatic, four stand and five site variables have been tested in the binary logistic regression model. Statistically significant predictors were the sum of snow cover in spring months (March, April, May), phytogeographical region, rockiness, slope inclination, and bedrock. The probability of occurrence of snow damage increases with the increasing amount of snow in spring months, with increasing slope inclination, and with decreasing rockiness. The probability of snow damage occurrence in beech forests, at the constant amount of snow, was 4,2-times higher in the predinaric region, 3,4-times higher in dinaric region and 1,9-times higher in the prealpine phytogeographical region if compared to the alpine phytogeographical region. Beech was found as less susceptible to snow damage compared to spruce, therefore the reasons for relatively high sanitary fellings can partly be explained by alterations in forests due to the admixture of spruce. In terms of stands' mechanical stability, thinnings ought to be of lower intensities and carried out in shorter intervals.

Izhodišče diplomskega projekta so davki. Države z davki izpolnjujejo fiskalne, socialne in ekonomske cilje. S plačevanjem davkov omogočamo obstoj in razvoj države, z njimi pa imajo davkoplačevalci obveznosti in tudi privilegije. Zaradi visokih davčnih stopenj in različnih drugih razlogov pride do zatajitev finančnih obveznosti, s katerimi se srečujemo povsod po svetu. Razlikujemo med zakonsko dovoljenim in zakonsko nedovoljenim neplačevanjem davkov. Pri zakonsko nedovoljenem plačevanju davkov obveznosti gre za nepravilno oziroma kaznivo dejanje davkoplačevalcev, ki ostaja dalj časa neodkrito. Zakonsko nedovoljenim zatajitvam finančnih obveznosti sledijo sankcije. V vsaki državi obstajajo razni zakoni, zakoniki ali druge uredbe, ki urejajo to področje. Osrednji problem diplomskega seminarja so razlike v sankcijah, ki za zatajitve finančnih obveznosti obstajajo v različnih državah. V diplomskem projektu opredeljujemo pojem zatajitev finančnih dejavnikov, metode zatajitve finančnih obveznosti in dejavnike, ki vplivajo na pogostost zatajitve. Osredotočamo se na sankcioniranje zatajitev finančnih obveznosti v naslednjih državah: Slovenija, Hrvaška, Nemčija in Amerika. The starting point of this thesis are taxes. With taxes countries comply the fiscal, social and economic goals. By paying taxes, taxpayers have obligations as well as privileges. By paying taxes we guarantee the existence and evelopment of the country. Due to the high tax rates and various other reasons we encounter on tax evasion. Tax evasion is encountered everywhere in the world. We distinguish between legally approved and legally illicit non-payment of taxes When we talk about legally illicit payment of tax we usually think about an offence of the taxpayer that remains undiscovered for a long time. Legally illict tax evasions are followd by sanctions. In every country there are various laws, codes or other regulations regulating this area. The main problem of this thesis are the differences in sanctions that exist for tax evasion in different countries. In the bachelor thesis we define the concept of tax evasion, methods of tax evasions and influencing factors that affect the frequency of tax evasion. We focus on sanctioning of tax evasion in the following countries: Slovenia, Croatia, Germany and America

Diplomsko delo obravnava problematiko, kako zagotoviti primerno in pravočasno porabo posipnega materiala za zimsko vzdrževanje cest. Na primeru cestnega podjetja Nova Gorica je bila izdelana analiza trenutnega stanja, popis trenutno uporabljenih modelov in primerjava tega z dejanskim stanjem. Na podlagi trenutnega modela je bil predlagan nov model, z utežnimi koeficienti, ki se v primerjavi z obstoječim, bolje približa dejanskemu stanju hkrati pa vključuje vpliv specifičnih vremenskih pogojev za posamezne cestne odseke. Predlagani model tudi zmanjša porabo posipnega materiala in obremenitev le tega na okolje, hkrati pa naredi posip ekonomsko učinkovitejši. The thesis deals with the problem of how to provide adequate and timely consumption of spreading material for winter road maintenance. For example, we choose Road company Nova Gorica and, do the analysis of the current situation, with the current inventory of the models used and we did comparison of this with current situation. Based on current model, we propose a new model, with the weighting coefficients to be compared with the existing one, at the same time, aproches closest to the actual situation but also includes the impact of specific weather condition for individual road sections. The proposed model also reduces the consumption of grit material and the burden thereof on the environment, but do the shake economically efficient.

Dolgoročno dinamiko jelovo-bukovih gozdov v Sloveniji v treh prostorsko ločenih objektih (Leskova dolina, Trnovo in Jelovica) smo proučevali s podatki, ki smo jih pridobili iz gozdnogospodarskih načrtov in gozdarskih kart. Podatkovna zbirka GIS je obsegala podatke iz obdobja po letu 1897 za Trnovo, po letu 1899 za Jelovico in po letu 1912 za Leskovo dolino. Za analizirano obdobje smo ugotovili znatne spremembe proučevanih sestojnih znakov (debelinske strukture, lesne zaloge, raznolikosti debelinske strukture in drevesne sestave). Med objekti je različna velikost in usmerjenost sprememb sestojnih znakov. Nanje vplivajo mnogi dejavniki med pomembnejšimi so prejšnja raba gozdov, vpliv velikih rastlinojedov in rastiščne razmere. The long-term dynamics of silver fir-European beech forest stands in Slovenia were studied in three geographically dislocated study areas, Leskova dolina, Trnovo and Jelovica. In the study archival forest management plans and maps for the past century were used to create the GIS database. It included the data for the period after 1897 for Trnovo study area, after 1899 for Jelovica study area, and after 1912 for Leskova dolina study area. Substantial changes in diameter structure, stand volume, tree size diversity and tree species composition were documented, significantly differing between the study areas. Found stand dynamics were underpinned by a complex array of influential factors, among which past forest use, the impact of large ungulates and site conditions stood out.

Namen magistrske naloge je bil proučiti medsebojno odvisnost davčne kulture in davčne utaje v izbranih državah. Da bi dosegli zastavljen namen magistrske naloge, smo si zastavili različne cilje. Le-te smo razporedili v dve skupini, in sicer na teoretične in empirične cilje. Naša naloga je bila najprej proučiti in predstaviti pojem davčne kulture, izpostaviti nekaj izbranih definicij ter predstaviti oblikovanje davčne kulture. V nadaljevanju smo nato proučili in predstavili pojem davčne utaje, najpogostejše motive davčnih utaj, kategorizirali davčne utaje v različne vrste po določenih kriterijih in se dotaknili še zakonodaje, ki ureja kaznovanje davčnih utaj v Sloveniji. Proučili in predstavili smo nekaj izbranih študij iz obravnavanega področja in na ta način zbrali vplivne dejavnike, ki smo jih po posameznih študijah povzeli v tabeli. Nato smo izvedli lastno raziskavo, v katero smo zajeli 47 naključno izbranih držav. Opredelili smo odvisno spremenljivko, ki jo predstavljajo davčne utaje in neodvisne spremenljivke: zaupanje v vlado, religija, učinkovitost vlade, vplivnost, individualizem, patriarhizem, izogibanje negotovosti ter BDP na prebivalca. Raziskavo smo izvedli s pomočjo regresijske analize ob uporabi metode najmanjših kvadratov. Prva ugotovitev magistrskega dela je, da višja kot je stopnja individualizma, manjša je stopnja davčnih utaj, torej, če se poveča stopnja individualizma, se zmanjša stopnja davčnih utaj. Naslednja ugotovitev je, da med spremenljivko patriarhizem in davčnimi utajami obstaja pomembna povezava. Višja kot je stopnja izogibanja negotovosti, manjša je stopnja davčnih utaj. Zadnja ugotovitev magistrskega dela je, da višja kot je stopnja vplivnosti posameznika, višja je stopnja davčnih utaj v državi. To pomeni, da predstavlja višja stopnja vplivnosti posameznika, višjo stopnjo davčnih utaj v državi. My master's thesis is aimed at researching the interdependence between tax culture and tax evasion in some selected countries. To achieve the aim of our thesis we set two types of goals – the theoretical and empirical goals. Firstly, the term of tax culture was studied and presented moreover, some definitions and the formation of tax culture were presented. In addition, the term of tax evasion was studied and presented, followed by the most frequent tax evasion motives. Furthermore, tax evasion was categorised into different types according to specific criteria and the legislation regulating the tax evasion punishment in Slovenia was presented. Some selected studies regarding the topic were presented and studied to select the influencing factors which are summed up in tables according to individual study. After that we carried out our own research including 47 coincidentally chosen countries. We defined the dependent variable – the tax evasion and the following independent variables: trust in government, religion, government effectiveness, power distance, individualism, masculinity, uncertainty avoidance and GDP per capita. The research was carried out with the help of a regression analysis by using the least squares method. The first finding of our master’s thesis was the following: the higher is the individualism level the lower is the tax evasion level, i.e. when the individualism level is increasing, the tax evasion level is decreasing. This is the following finding: there is an important linking between the masculinity variable and the tax evasion variable and the higher is the uncertainty avoidance level, the lower is the tax evasion level. The last finding is the following: the higher is the level of power distance of an individual, the higher is tax evasion level in the country, which means that a higher level of power distance of an individual is increasing the tax evasion level in the country.

V diplomskem delu smo preučevali vpliv temperature, časa in konzerviranja na vsebnost težkohlapnih lipofilnih snovi (TLS) v vzorcih industrijskih odpadnih vod. TLS so nepolarne ali šibko polarne snovi, ki imajo temperaturo vrelišča nad 250 °C. Gre za mineralna, rastlinska in živalska olja, maščobe, masti in voske. Po drugi definiciji gre za vsoto ekstrahiranih nepolarnih ogljikovodikov, ki so določeni z gravimetrično metodo po sušenju na temperaturi 80 °C. Vsebnost TLS smo določili z gravimetrično metodo, ki je temeljila na standardni metodi SIST ISO 11349:2011. Vzorec odpadne vode smo homogenizirali, ekstrahirali s heksanom, nato smo topilo odparili s pomočjo rotacijskega vakuumskega uparjalnika in vzorec stehtali. Rezultati kažejo, da se vsebnost TLS spreminja pod vplivom temperature in časa, medtem ko 7-dnevno konzerviranje pri temperaturi 4 °C in dodatek H2SO4 ohranita vsebnost TLS. Uporabljena metoda je tako primerna za analize, ki se izvedejo v roku 7 dni. Koncentracija TLS se poveča z dvigom temperature na 40 °C (višja ekstrakcijska hitrost) in zmanjša s časom (poteče proces oksidacije). V kislem mediju pri pH

Namen magistrske naloge je bil, da se je preverilo, katere spremenljivke vplivajo na pojav odmiranja dreves. Eden od namenov je bil tudi, da se na podlagi stalnih vzorčnih ploskev Zavoda za gozdove Slovenije ugotovijo zakonitosti pojavljanja odmrlega drevja v Zasavju. S podrobnejšo terensko analizo pa ugotovi značilnosti prostorske razmestitve velikih lesnih ostankov.Pri analizi podatkov se je uporabilo Clark in Evansov indeks ter Ripleyevo K(t) funkcijo. Analizo podatkov pojava odmrlih dreves na stalnih vzorčnih ploskvah pa je bila izvedena s pomočjo logistične regresije. Analiza je pokazala, da imajo bukev, plemeniti listavci in beli gaber manjšo verjetnost kot iglavci, da odmrejo. Posek, višja temeljnica iglavcev ter večji prsni premer drevesa glede na mediano zmanjšujejo verjetnost pojav odmrlih dreves. Kostanj, poškodovanost in naklon pa povečujejo verjetnost odmiranja. Pri analizi podatkov s terena pa se je izkazalo, da različni testi podajo neenake rezultate. Pri večini ploskev velikosti 1 ha, na podlagi Ripleyeve K(t) funkcije se je ugotovila naključna razmestitev velikih lesnih ostankov, za precejšen del ploskev pa je bila značilna šopasta razmestitev. Največji delež ploskev s šopasto razmestitvijo je bil na razdalji 18 metrov. Med odmrlimi ostanki, kjer so bile opravljene terenske meritve, je prevladovalo ležeče mrtvo drevje, med drevesnimi vrstami sta prevladovali smreka in bukev. Največ je bilo odmrlih drevesnih ostankov v prvem razširjenem debelinskem razredu, najmanj pa v tretjem. The purpose of the master's thesis has been to examine which variables influence on the onset of tree deaths. The main goal has been to figure out the laws governing the occurrence of the tree deaths in Zasavje on the basis of permanent sample plots of Slovenia Forest service. Detailed field analysis has been used to determine the characteristics of the spatial distribution of large woody debris. Clark's and Evansʼs index and Ripley's K(t) function have been used for the data analysis. Logistic regression has been used for the data analysis on the occurrence of tree deaths in the permanent sample plots .The analysis has showed that beech, valuable broadleves and hornbeam are lesslikely to die than conifers. Cutting, higher basal area of conifers and increased breast diameter of the trees according to the median reducing the probability of occurrence of tree deaths. On the other hand, chestnut, tree damage and slope are increasing the probability of tree deaths. Dissimilar results have been obtained from various tests in data analysis from the field.Random distribution of large woody debris have been found at the majority of plots sized 1ha on the basis of Ripley's K(t) function but a considerable part of plots have been characterized as a clustered distribution. The largest proportion of plots with cluster distribution has been at the distance of 18 meters. Field measurements have been conducted among the dead tree remains and it has been dominated by lying dead trees. Spruce and beech have been dominated among the tree species. Most of the dead tree remains have been in the first diameter class and at least in the third class.

Leta 2008 je viharni veter v osrednji Sloveniji na območju 20.000 ha poškodoval več kot 500.000 m3 lesne mase, popolnoma uničenih je bilo 700 ha gozdov. Raziskava je bila omejena na območje prelaza Črnivec (GGE Gornji Grad,GGO Nazarje). S 320 stalnih vzorčnih ploskev (SVP) se je z multivariatnimi metodami in logistično regresijo analiziralo podatke o drevju in gozdnih sestojih. Želelo se je ugotoviti, katere rastiščne in sestojne značilnosti vplivajo na obseg in stopnjo poškodovanosti sestojev in podati priporočila, kako pri gospodarjenju z gozdovi zmanjšati tveganja zaradi vpliva močnih vetrov. Podatki s SVP in drugo gradivo (sestojna karta, aerofoto posnetki, karta poškodovanosti) so bili dobljeni na Zavodu za gozdove Slovenije, Območna enota Nazarje. V model pojava vetroloma je bilo vključenih sedem od sedemindvajsetih spremenljivk: nadmorska višina, lega, naklon, lesna zaloga smreke, jelke in bukve ter matična podlaga. Med njimi je bila najpomembnejša matična podlaga, saj se na silikatni matični podlagi verjetnost pojava vetroloma zmanjša za količnik 0,37. Pomemben dejavnik je bila tudi lega, saj je verjetnost pojava vetroloma 1,48-krat višja na privetrni strani kot na zavetrni. Rezultati tudi kažejo, da je stopnja poškodovanosti sestojev z večjo primesjo listavcev znatno nižja. In the year 2008 the stormy wind in central Slovenia destroyed more than 500,000 m3 of wood mass at an area of 20,000 hectares. 700 hectares of forests were completely destroyed. This research focuses on the mountain pass Črnivec area (the forest economic unit Gornji Grad in the forest economic area Nazarje). 320 permanent sample plots (PSP) were analysed with multi-version methods and logistic regression to collect data on trees and forest stands. The aim was to find out which characteristics of sites and stands have influence on the scale and level of damage on stands, as well as give recommendations concerning the reduction of high winds hazard in forest management. The data from PSP and other material (stand map, air photos, damage map) was obtained from the Slovenian Forest Service, regional unit Nazarje. The windfall occurrence model includes seven of twenty-seven variables: altitude, location, incline, wood stock of spruce, fir and beech, and bedrock. The most important among them is the bedrock, since the chance of windfall decreases for a quotient of 0.37 on a silicate ground. Another important factor is the location the chance of windfall is 1.48 higher at the windward side then at the leeward side. The results show that the damage level on stands with more deciduous trees is far lower.

Leta 2006 je orkan porušil 125 hektarjev enomernih smrekovih debeljakov na planoti Jelovica (GGE Jelovica, GGO Bled). Raziskava naj bi pokazala: 1) uspešnost naravne obnove na vetrolomni površini in 2) vpliv izbranih rastiščnih in sestojnih dejavnikov na pojavnost in gostoto pomladka drevesnih vrst. Na terenu je bila zakoličena mreža 81 stalnih vzorčnih ploskev (4 x 4 m)z gostoto 100 x 200 m, na katerih so bile opisane rastiščne in sestojne razmere ter analizirano število, sestava in višinska struktura pomladka (dbh
