Energetsko učinkovit sistem za detekcijo slonov s pomočjo strojnega učenja

Human-Elephant Conflicts are a major problem in terms of elephant conservation. According to WILDLABS, an average of 400 people and 100 elephants are killed every year in India alone because of them. Early warning systems replace the role of human watchers and warn local communities of nearby, potentially life threatening, elephants, thus minimising the Human-Elephant Conflicts. In this Master\u27s thesis we present the structure of an early warning system, which consists of several low-power embedded systems equipped with thermal cameras and a single gateway. To detect elephants from captured thermal images we used Machine Learning methods, specifically Convolutional Neural Networks. The main focus of this thesis was the design, implementation and evaluation of Machine Learning models running on microcontrollers under low-power conditions. We designed and trained several accurate image classification models, optimised them for on-device deployment and compared them against models trained with commercial software in terms of accuracy, inference speed and size. While writing firmware, we ported a part of the TensorFlow library and created our own build system, suitable for the libopencm3 platform. We also implemented reporting of inference results over the LoRaWAN network and described a possible server-size solution. We finally a constructed fully functional embedded system from various development and evaluation boards, and evaluated its performance in terms of power consumption. We show that embedded systems with Machine Learning capabilities are a viable solution to many real life problems.Konflikti med ljudmi in sloni predstavljajo velik problem ohranjanja populacije slonov. Zaradi fragmentacije in pomanjkanja habitata sloni, v iskanju hrane, pogosto zaidejo na riževa polja in plantaže, kjer pridejo v stik s človekom. Po podatkih skupnosti WILDLABS, zaradi konfliktov, samo v Indiji, letno umre povprečno 400 ljudi in 100 slonov. Sistemi zgodnje opozoritve nadomeščajo vlogo človeških stražarjev in opozarjajo bližnjo skupnost o bližini, potencialno nevarnih, slonov in tako pripomorejo k zmanjševanju konfliktov med ljudmi in sloni. V tem magistrskem delu predstavljamo strukturo sistema zgodnje opozoritve, ki je sestavljen iz večih, nizko porabnih, vgrajenih sistemov, ki so opremljeni s termalnimi kamerami in ene dostopne točke oz. prehoda (gateway). Vgrajeni sistemi so postavljeni na terenu, ob zaznavi slona pošljejo opozorilo preko brezžičnega omrežja do dostopne točke, ki nato lahko opozori lokalno skupnost. Za prepoznavo slonov iz zajetih termalnih slik smo uporabili metode strojnega učenja, bolj specifično konvolucijske nevronske mreže. Glavni cilji tega magistrskega dela so bili zasnova, izvedba in ovrednotenje modelov strojnega učenja, ki jih je možno poganjati na mikrokrmilnkih pod pogoji nizke porabe

Ranosrednjovjekovno likovno stvaralaštvo u Sloveniji

After the decline of the late antique material culture in the beginning of the 7th century, the first attempts of craft creativity in Slovenia are visible at the end of the 7th century -by introducing western figural style on circular brooches. We can speak about the real medieval art and craft creativity in Slovenia as late as the beginning of the 9th century and it is closely connected with christianisation (supported by the Prankish state). This creativity can be recognized in architecture (among the increasing number of churches mentioned in the 9th and 10th century only 6 of them are excavated), in sculpture with interlaced ornament (among 40 known examples only 3 are from the northeastern part of Slovenia, the others from Koper and its surroundings) and especially in the jewelry of the so called Kottlach culture (enameled semicircular earrings and circular brooches, usually with christian motifs)

Using socrates against today's education for labour market

U globalnom svijetu promjene se događaju svakodnevno i zahvaćaju odgojno-obrazovni sustav. Tome u prilog govori činjenica da se većina tradicionalnih smjernica odbacuje, te se teži novim ciljevima i metodama, onim izvanjskim koje zadovoljavaju neprestano mijenjajuće tržište rada. Svrha pojedinca u takvom sustavu jest prilagoditi mu se odgovarajući na njegove potrebe, dok Sokrat traži sreću unutar čovjeka – čovjeka koji posjeduje znanje i mudrost ne zbog drugih već zbog sebe i svoje slobode. Svojom metodom dijalektičkog govora traži istinu u sebi i drugima te nudi mnogo toga za promišljanje. Njegovo poučavanje koje ističe ljubav prema učenju i želju za istinskim znanjem koji stvaraju zrelog i autonomnog čovjeka svakako nadahnjuju već 25 stoljeća te bi ga trebalo uzeti u obzir kada se promišlja o budućnosti mladih generacija koje dolaze. U ovom radu uspoređujemo odgoj i obrazovanje danas s onim koje je bilo uvriježeno u Sokratovo doba te nastojimo ukazati na razlike. U radu se ističu promijene koje su zahvatile sveučilišta u vidu Bolonjske deklaracije ali i kako ih usmjerenost prema tržištu rada pretvara u poduzetničke centre. Što to znači za društvo znanja kojemu težimo i možemo li uopće tvrditi da zaista jesmo društvo znanja ukoliko stremimo isključivo znanjima diktiranima od strane neprestano mijenjajućeg tržišta rada? Uspoređujemo znanje kojemu težimo sa znanjem kojega je tražio Sokrat ukazujući pri tome na nedostatke današnjeg odgoja i obrazovanja te nudimo Sokratove ideje i mišljenja kao mogući pomak prema istinskoj mudrosti.In the global world, changes that strike our educational system, ocurr daily. In that matter, most of the traditional guidelines have been thrown away in order to strive new goals and methods, the external ones, which satisfy the constantly changing labor market. The purpose of an individual in that kind of a system is to adapt in order to satisfy its needs while Socrates searches for happiness inside a man itself- a man possesses knowledge and wisdom for himself and his own freedom, not others. With his method of dialect speech, he seeks his own truth and for others, and offers lots to think about. His teaching emphasizes love and desire for learning and true knowledge that leads to becoming an independent man inspires people for over 25 centurires and it should be taken into consideration when thinking about youth, younger generations and their future. In this paper, we are comparing and showing the differences in education today and the one in Socrates time. The changes through Bologna Declarationnare especially accented, so the directionality in the labor market makes the universities 4 entrepenurial centres. What does that mean for the knowledge economy we are thriving for? Can we even state that we really are the knowledge economy as we aspire the knowledge that is dictated by constantly changing labour market? We compare the knowledge to which we aspire with the knowledge which Socrates searches for and shows the disadvantages of today’s educational system. Here we offer Socrates ideas and opinions which lead to a possible progess to the genuine wisdom

Primjenjivost Sokratove metode odgoja u odgoju i obrazovanju danas

In the global world, changes that strike our educational system occur daily. In that matter, most of the traditional guidelines have been thrown away in order to strive towards new goals and methods, the external ones, which satisfy the continually changing labor market. The purpose of an individual in that kind of a system is to adapt in order to satisfy its needs while Socrates searches for happiness inside a man itself - a man possesses knowledge and wisdom for himself and his freedom, not others. With his method of dialectic speech, he seeks his truth and that of others and offers lots to think about. His teaching, which emphasizes love and desire for learning and real knowledge that leads to becoming an independent man, has been inspiring people for over twentyfive centuries, and it should be taken into consideration when thinking about youth, younger generations, and their future. In this paper, we are comparing and showing the differences in education today and the one in Socrates’ time. This paper highlights changes brought by the Bologna Declaration, but also the directionality in the labor market today, which makes the universities entrepreneurial centers. What does that mean for the knowledge economy we are striving for? Can we even state that we really are a knowledge society if we only aspire to knowledge that is dictated by the constantly changing labour market? We compare the knowledge to which we aspire with the knowledge which Socrates searches for and show the disadvantages of today’s educational system along the way. Here we offer Socrates’ ideas and opinions, which lead to possible progress towards genuine wisdom.U globalnom svijetu promjene se događaju svakodnevno i zahvaćaju odgojnoobrazovni sustav.

Novejše antične najdbe na Gorenjskem

Im vorliegenden Text werden zwei neue antike Fundorte in Gorenjsko vorgestellt, im Umfang, wie sie bei der topographischen Sondierung entdeckt wurden. S p o d n j e B i t n j e b e i K r a n j (Taf. 1: 1-18; 2: 1-13) AnlaBlich des Suchens nach der (vor)romanischen Kirche des hi. Veit, die bis zum 16. Jh. neben der gegenwartigen kleinen Kirche des hi. Nikolaus stand1-4, wurde die Mauer eines spatantiken Gebaudes freigelegt, das die gefundene Keramik ungefahr ins 3. Jh. datiert,5-14 das jedoch auch verwandte Ziige mit der benachbarten villa rustica in Žabnica aufweist . Z a s i p b e i B l e d (Taf. 3: 1-18; Abb. 4, 5) Die Sondierung im Jahr 1984 hat auBer den Uberresten eines mittelalterlichen Gebaudes, das vermutlich das Wohnhaus der Gorzer-Brixener Ministerialen (Bleder - Zasiper) Reynman aus dem 13. bis 14. Jh. darstellt,16-22 auch den Teil eines Gebaudes freigelegt, das - in Hinsicht auf die Keramikfunde - antik sein diirfte. Die Keramik ist reichlich atypisch, grob, von Hand verfertigt. Es handelt sich hauptsachlich um Backhauben zweier Typen und sparliche Reste von Topfen mit Besenstrichornament.

A hoard find from Grdavov hrib near Radomlje

V poznoantični naselbini Grdavov hrib pri Radomljah je bil leta 1996 odkrit depo sočasnega orodja, nedvomno namenjenega obdelavi lesa. S sondiranjem in preverjanjem natančne lokacije so bile odkrite še druge naselbinske najdbe. Novost v članku predstavljata interpretacija nazobčanega polmesečastega rezila kot sestavni del sodarskega orodja (t. i. utorovnika) ter določitev namembnosti ukrivljenemu, na eni strani gibljivo vpetemu rezilu – verjetno so ga uporabljali kot sekač za obdelavo lesenih izdelkov. Orodje iz zakladne najdbe je funkcionalno poenoteno in po vsej verjetnosti predstavlja inventar poznorimske tesarske delavnice iz druge polovice 4. stoletja. S sočasnimi sorodnimi najdbami nakazuje postopen prehod k pretežno leseni gradnji v poznorimskem obdobju.A hoard of woodworking tools from Late Antiquity was found in 1996 within the settlement from the same period on the hill of Grdavov hrib near Radomlje. The find was followed by trial trenching, which revealed other settlement finds. The article offers a new interpretation of the object with a crescent-shaped serrated blade as part of a barrel-making implement (so-called croze), as well as an interpretation of the tool with a curved blade ending in a loop at one end and a tang at the other, which presumably served as a woodworking pile-knife. The tools of the hoard are functionally uniform and most likely represent the tool kit of a Late Roman carpenter’s workshop from the second half of the 4th century. Together with comparable finds, the tool kit is evidence of the gradual transition, in the Late Roman period, to houses and other buildings mainly constructed of wood

Poselitev Kranja v starejši železni dobi – pregled raziskav

The article provides an overview of the field research to date in Kranj, which have yielded material from the early and late Hallstatt period. The extent of settlement in the Hallstatt period, evidenced by the spread of finds, is relatively large and exceeds the size of the later medieval city. Grave finds from the Hallstatt period are consistently concentrated on the northern outskirts of the town, on the former river terrace. Bronze Age finds are very rare and without contexts in the form of structures. The amount of finds from individual phases of the Early Iron Age shows that the settlement reached its peak in its initial phase (Ha B3/C1). In the later phases, it still maintained its size, but settlement was less intensive. The transition to the La Tène and early Roman periods took place without interruption. During the early and late Hallstatt periods, the surroundings of Kranj were also quite intensively inhabited, especially Šmarjetna gora and Stražišče lying below it.V prispevku prinaša pregled dosedanjih raziskav v Kranju, ki so prinesle gradivo iz starejšega in mlajšega halštatskega obdobja, ter temu gradivu posvečene literature. Obseg naselbine v halštatski dobi, ki ga nakazuje razprostranjenost najdb, je razmeroma velik in presega velikost poznejšega srednjeveškega mesta. Grobne najdbe iz halštatske dobe so dosledno skoncentrirane na severno obrobje mesta, na rob nekdanje rečne terase. Bronastodobne najdbe so izrazito redke in brez kontekstov v obliki struktur. Količina najdb iz posameznih faz starejše železne dobe kaže, da je naselbina dosegla vrhunec v svoji začetni fazi (Ha B3/C1), medtem ko je v mlajši fazi sicer še ohranila svoj obseg, a je bila poselitev manj intenzivna. Prehod v latensko dobo in zgodnjo antiko je potekal brez prekinitve. V času starejšega in mlajšega halštatskega obdobja je bila dokaj intenzivno poseljena tudi okolica Kranja, zlasti Šmarjetna gora in pod njo ležeče Stražišče
