Optimization methods for a direct current electric motor design : magistrsko delo
Vid Černec, 2022, magistrsko delo

Opis: In the modern world, the need for planning in advance has become increasingly important. The companies want to know the cost, the dimensions of the elements, and the properties of the final product in advance. Therefore, we can find teams working on the analysis and development of new and different products in larger companies. More experienced workers can determine the given results and see what would be acceptable by simply looking at the situation. Although, the help of technology makes the process easier and faster, and even provides the same result. When creating a specific model, we must focus on the equations describing our result. Then we begin with optimization, which means we define the variables, which will be our subject of research in the project, and define some fixed parameters until the desired goals are reached.
Ključne besede: design, DC electric motor, optimization, optimization algorithms, genetic algorithms

Izgradnja električnega ojačevalnika za piezoelektrični aktuator
Gregor Korže, 2022, diplomsko delo

Opis: V okviru diplomskega dela je bil izdelan hladilni sistem za električni ojačevalnik, ki ga uporabljamo za napajanje piezoelektričnih aktuatorjev. Preračunali smo temperature spoja ojačevalnika, izbrali ustrezen hladilnik in določili ustrezne ventilatorje za aktivno hlajenje sistema. Električni ojačevalnik smo nato testirali pri vhodnih signalih različnih frekvenc in amplitud, ob tem pa smo opazovali izhodni signal in temperaturo ohišja močnostnega ojačevalnika PB51. S programom Apex Power Design smo opravili analizo stabilnosti sestavljenega električnega ojačevalnika. Za lažje in bolj kvalitetno zajemanje fotografij in posnetkov smo 3d natisnili tudi nastavek za mobilni telefon, ki se pritrdi na okular mikroskopa. Tako lahko sedaj zajemamo počasne posnetke kroženja vode na mikroskopskem stekelcu, kar nam bo olajšalo nadaljnje raziskave na področju mikrofluidnih motorjev.
Ključne besede: Močnostni ojačevalnik, piezoelektrični aktuator, hladilni sistem, 3d tiskanje, SolidWorks, Apex Power Design.

Importance of business models in circular economy : bachelor thesis
Fernández Gómez Raquel, 2022, diplomsko delo

Opis: This bachelor thesis studies and analyzes the importance of business models in the Circular Economy. The company studied is an SME, i.e. 10 to 250 employees. The smaller companies are mainly confronted with the problem of resources, and the larger ones with their strategic orientation. The aim is to generate a guideline or way of doing that serves as a model for the SMEs already created so that the transition from the Linear Economy, which is still predominant today, to a Circular Economy. The idea is, after the study, a real case study of SMEs working with the premises of CE to establish a market model that follows the same. To support changes, we have documented the different business models currently in use, choosing the Canvas Business Model for several reasons and making the various changes necessary to make this a sustainable and circular model. In addition, it is established that the process of innovation and modification must be applied as a continuous cyclical process. If the company wants to be successful, it is a continuous cycle model, which should never stop.
Ključne besede: Business Models for Circular Economy, Business Model Canvas, Industrial symbiosis, Ressource efficciency, Synergies, Sustainable development, CE in SMEs, Circular Economy, Product Sustainable Design.

Parametrični vplivi na kakovost in zanesljivost merilnega vezja : učbenik
Vojko Matko, 2022, učbenik

Opis: Vsebina obsega vplive posameznih parametrov na kakovost in zanesljivost merilnega vezja. Parametrični pristop daje zelo natančen kakovostni pregled nad vplivi parametrov vezja, vplivnimi količinami in tudi optimiranju merilnih vezij v smislu “ECO (Ecology) design-a”. Ta je predpisan z evropsko direktivo 2009/125 /CE in postavlja okvir za določitev zahtev za okoljsko primerno zasnovo izdelkov, povezanih s čim manjšo porabo električne energije. Ob upoštevanju te direktive pa moramo ob zmanjšanju porabe energije posameznih vezij tudi preverjati kakovost in zanesljivost delovanja, kar je v tem učbeniku osredotočeno na področje merilne negotovosti merilnih vezij. Pomembne pridobitve parametričnega pristopa so, da v končni analizi dobimo informacijo o velikostnih redih posameznih parametričnih vplivov, da izboljšamo kakovost v smislu izboljšanja merilne negotovosti ob sočasnem zmanjšanju porabe električne energije in predvsem, da dobimo informacijo kako izboljšati vezje. Vsebina te publikacije je splošno uporabna tudi pri drugih predmetih študija splošne elektrotehnike.
Ključne besede: vpliv parametrov, analize parametrov, merilna negotovost, zanesljivost delovanja, »eco design«

Oblikovanje multifunkcionalnega stojala za gojenje zelišč v stanovanju : magistrsko delo
Monika Hudournik, 2022, magistrsko delo

Opis: Ljudje se vedno bolj zavedajo prednosti sveže in naravno pridelane hrane, ki jo je vedno težje najti. Tudi zelišča, ki jih uporabljamo skozi celo leto. Veliko ljudi želi gojiti zelišča v stanovanju, vendar imajo velikokrat premalo prostora in neprimerne pogoje za gojenje ter premalo časa in znanja za vzgojo rastlin. Z razvojem izdelka, osredotočenim na uporabnika, ki je potekal skozi faze metode design thinking, smo oblikovali multifunkcionalni sobni vrtiček z ambientalno lučjo. Ta bo omogočal enostavno gojenje več zelišč na majhnem prostoru in v stanovanje prinesel košček narave, ob katerem se bo uporabnik lahko sprostil.
Ključne besede: produktno oblikovanje, design thinking, notranji vrt, zelišča, multifunkcionalnost, modularnost

Retaining structure in demanding ground conditions: PK-16, road Hrastnik - Zidani Most : master's thesis
Aleksandr Sokolov, 2021, magistrsko delo

Opis: The master thesis presents the findings of the review of the design documentation of PGD plans for the PK-16 retaining structure, reconstruction of the G2-108 Hrastnik - Zidani Most road and deviation of the G1-5 Rimske Toplice - Zidani Most - Radeče road. The PK 16 retaining structure is foreseen between the Sava riverbed and the new road. The length of the retaining structure is substaintal (approx. 1140 m), the morphology of the terrain along the wall varies greatly. However, due to the erosion of the Sava River, it is estimated that the wall will need to be deep or corrosion protection should be constructed. Temporary security and work platforms based on the Sava River Basin (which is already impounded and quite deep in this part) will be required. The retaining structure is designed as a vertical cantilever wall that is on the underside rigidly fixed to the horizontal foundation plate. On the bulk of the structure, the foundation plate is supported by piles in two rows. The vertical wall at the top passes into a horizontal cantilever along which a corridor with a fringe runs. The controlling calculations were done employing a computational 2D model that takes into account the elastoplastic Mohr - Coulomb model for soil and the elastic model of concrete structures. The accompanying geotechnical calculations of the retaining structure in profiles P283 and P299 were compared with the analyses made in the design project to confirm the possibility of carrying out the proposed structures.

Ensemble Docking Coupled to Linear Interaction Energy Calculations for Identification of Coronavirus Main Protease (3CLpro) Non-Covalent Small-Molecule Inhibitors
Marko Jukič, Dušanka Janežič, Urban Bren, 2020, izvirni znanstveni članek

Opis: SARS-CoV-2, or severe acute respiratory syndrome coronavirus 2, represents a new strain of Coronaviridae. In the closing 2019 to early 2020 months, the virus caused a global pandemic of COVID-19 disease. We performed a virtual screening study in order to identify potential inhibitors of the SARS-CoV-2 main viral protease (3CLpro or Mpro). For this purpose, we developed a novel approach using ensemble docking high-throughput virtual screening directly coupled with subsequent Linear Interaction Energy (LIE) calculations to maximize the conformational space sampling and to assess the binding affinity of identified inhibitors. A large database of small commercial compounds was prepared, and top-scoring hits were identified with two compounds singled out, namely 1-[(R)-2-(1,3-benzimidazol-2-yl)-1-pyrrolidinyl]-2-(4-methyl-1,4-diazepan-1-yl)-1-ethanone and [({(S)-1-[(1H-indol-2-yl)methyl]-3-pyrrolidinyl}methyl)amino](5-methyl-2H-pyrazol-3-yl)formaldehyde. Moreover, we obtained a favorable binding free energy of the identified compounds, and using contact analysis we confirmed their stable binding modes in the 3CLpro active site. These compounds will facilitate further 3CLpro inhibitor design.

The direct and indirect relationships between design orientation and market orientation
Sanja Rocco, 2019, doktorska disertacija

Opis: The main purpose of this doctoral thesis is to investigate the relationship between design orientation and market orientation and propose a new conceptual model. Existing models were investigated. The initial conceptual model was proposed as the starting point. The research combined qualitative and quantitative methods. Quantitative research was conducted among managers and CEOs from Croatian companies in different industries. According to the final PLS-SEM model, design orientation has a direct and significant impact on market orientation and an indirect but significant impact on business success. Managerial approach has a direct and significant impact on design orientation, as well as on market orientation of a company. The new design orientation-market orientation model contributes to both marketing and design scholars, as well as implications for marketers, designers, and managers in practice. Our findings demonstrate that companies with higher level of market orientation and supported with design orientation also have the potential for achieving better results in the market and, consequently, better financial performance. It also provides the basis for future research on the topic.
Ključne besede: market orientation, design orientation, relationships, conceptual model, implications
