Nejc Trpin, 2021, magistrsko delo

Opis: Tehnologija se nenehno razvija in kot odraz na to se v poslovnem svetu pojavljajo različni koncepti, s pomočjo katerih lahko organizacije implementirajo najsodobnejše tehnologije kot so internet stvari, strojno učenje, napredna analitika in umetna inteligenca v svoje poslovanje. V zadnjih letih se vedno bolj govori o konceptu inteligentnih organizacij (angl. Intelligent enterprise), katere s pomočjo implementacije naprednih inteligentnih tehnologij v različnih industrijah uvajajo inovacije na raznih področji poslovanja ter s tem postavljajo mejnike tehnološkega napredka in strateškega razvoja za podjetja po vsem svetu. Ker številna podjetja, želijo doseči to inteligentno komponento poslovanja s pomočjo uvedbe koncepta inteligentne organizacije, so različni ponudniki programskih rešitev na trgu predstavili okvirje informacijske infrastrukture, nove programske rešitve in aplikacije, ki omogočajo integracijo najsodobnejših tehnologij v poslovanje. Eno takšnih podjetji je podjetje SAP, katero je na trg predstavilo svoj komplet rešitev za SAP inteligentno organizacijo. V prvem delu magistrske nalogo smo se posvetili pojmu inteligentne organizacije, ga pojasnili, opredelili smo katere pogoje morajo podjetja izpolnjevati, da jih lahko tretiramo kot inteligentne organizacije inteligentne organizacije in predstavili pogoje za opredelitev podjetja kot SAP inteligentne organizacije ter opredelili osnovno sestavo SAP inteligentnih organizacij. Raziskali smo napredne tehnologije inteligentnih organizacij ter preučili pojem rešitev ERP, saj rešitve ERP predstavljajo digitalno jedro inteligentnih organizacij. V nadaljevanju smo raziskovali različne metodologije, strategije in kritične dejavnike katere je potrebno upoštevati pri uvedbi koncepta inteligentne organizacije v podjetje. Sledila je podrobnejša analiza SAP S/4 HANA rešitve in drugih tehnologij, ki pogosto igrajo pomembno vlogo pri uvedbi koncepta inteligentne organizacij ter predstavljajo njihove ključne komponente digitalnega okvirja ter informacijske podpore. Drugi del magistrske naloge smo posvetili analizi treh študijskih primerov podjetij različnih panog, ki so v svoje poslovanje v določeni meri že uvedle koncept inteligentne organizacije s pomočjo rešitev podjetja SAP. Ob tem smo poskušali ugotoviti uspešnost implementacij koncepta v podjetja glede na njihove predhodno zastavljene cilje, preučili smo tudi katere rešitve so v posamezna podjetja bile implementirane, ter analizirali splošno stanje po uvedbi koncepta v podjetje. Ta del raziskave je predstavljal praktično osnovo, za potrditev ugotovitev iz teoretičnega dela.

Analytical solutions for one-dimensional consolidation in unsaturated soils considering the non-Darcy law of water flow
Jiwei Li, Huabin Wang, 2014, izvirni znanstveni članek

Opis: Analytical solutions were derived for the non-linear, one-dimensional consolidation equations for unsaturated soils. The governing equations with a non-homogeneous mixed-boundary condition were presented, in which the water flow was assumed to be governed by a non-Darcy law, whereas the air flow followed the Darcy law. The non-Darcy law was actually the non-linear, flux-gradients relationship. The consolidation equations were thus present in a strong, non-linear way. In order to analytically solve the equation, a homotopy analysis method (HAM) was introduced in the study, which is an analytical technique for nonlinear problems. Firstly, a governing equation in a dimensionless form was derived for a one-dimensional consolidation under unsaturated soils. The method was then used for a mapping technique to transfer the original nonlinear differential equations to a number of linear differential equations. These differential equations were independent with respect to any small parameters, and were convenient for controlling the convergence region. After this transferring, a series solution to the equations was then obtained using the HAM by selecting the linear operator and the auxiliary parameters. Meanwhile, comparisons between the analytical solutions and the results of the finite-difference method indicate that the analytical solution is more efficient. Furthermore, our solutions indicate that the dissipation of air pressure is much faster than that of water pressure, and the values for the threshold gradient I have obvious effects on the dissipation values of the excess pore-water pressure, but no significant effect on that of the excess pore-air pressure.

Multiphase approach to developing model of logistics for coastal tourist destinations
Sanja Bauk, Željko Ivanović, 2016, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: The process of urbanization of coastal tourist destinations (CTDs) is taking place at high speed and at the same time creating a lot of complex problems. The positive trend of urbanization has resulted in increased volume of freight transport which leads to burdening the traffic network, time losses and causes traffic congestion problems on the streets with increased environmental pollution due to emissions, noise and vibration. These findings brought to some research being started on the EU level, aiming to develop new logistic solutions, so these areas could be developed on a sustainable basis. With this in mind, the paper proposes a method of developing a novel model of logistics (MoL) for CTDs through several stages. The point of proposed MoL lies in achieving optimal connectivity of transportation, warehousing and physical distribution of goods, and making it a single functional model, so as to allow simultaneous optimization of logistic processes in a CTD, and to incorporate logistics in tourist offer.

Forward osmosis in wastewater treatment processes
Jasmina Korenak, Subhankar Basu, Malini Balakrishnan, Claus Hélix-Nielsen, Irena Petrinić, 2017, izvirni znanstveni članek

Opis: In recent years, membrane technology has been widely used in wastewater treatment and water purification. Membrane technology is simple to operate and produces very high quality water for human consumption and industrial purposes. One of the promising technologies for water and wastewater treatment is the application of forward osmosis. Essentially, forward osmosis is a process in which water is driven through a semipermeable membrane from a feed solution to a draw solution due to the osmotic pressure gradient across the membrane. The immediate advantage over existing pressure driven membrane technologies is that the forward osmosis process per se eliminates the need for operation with high hydraulic pressure and forward osmosis has low fouling tendency. Hence, it provides an opportunity for saving energy and membrane replacement cost. However, there are many limitations that still need to be addressed. Here we briefly review some of the applications within water purification and new developments in forward osmosis membrane fabrication.

Effect of drying parameters on physiochemical and sensory properties of fruit powders processed by PGSS-, vacuum- and spray-drying
Urban Feguš, Uroš Žigon, Marcus Petermann, Željko Knez, 2015, izvirni znanstveni članek

Opis: Aim of this experimental work was to investigate the possibility of producing fruit powders without employing drying aid and to investigate the effect of drying temperature on the final powder characteristics. Raw fruit materials (banana puree, strawberry puree and blueberry concentrate) were processed using three different drying techniques each opera- ting at different temperature conditions: vacuum-drying (–27–17 °C), spray-drying (130–160 °C) and PGSS-drying (112–152 °C). Moisture content, total colour difference, antioxidant activity and sensory characteristics of the proces- sed fruit powders were analysed. The results obtained from the experimental work indicate that investigated fruit pow- ders without or with minimal addition of maltodextrin can be produced. Additionally, it was observed that an increase in process temperature results in a higher loss of colour, reduced antioxidant activity and intensity of the flavour profile.

Towards the novel reasoning among particles in PSO by the use of RDF and SPARQL
Iztok Fister, Xin-She Yang, Karin Ljubič Fister, Dušan Fister, Janez Brest, Iztok Fister, 2014, izvirni znanstveni članek

Opis: The significant development of the Internet has posed some new challenges and many new programming tools have been developed to address such challenges. Today, semantic web is a modern paradigm for representing and accessing knowledge data on the Internet. This paper tries to use the semantic tools such as resource definition framework (RDF) and RDF query language (SPARQL) for the optimization purpose. These tools are combined with particle swarm optimization (PSO) and the selection of the best solutions depends on its fitness. Instead of the local best solution, a neighborhood of solutions for each particle can be defined and used for the calculation of the new position, based on the key ideas from semantic web domain. The preliminary results by optimizing ten benchmark functions showed the promising results and thus this method should be investigated further.

New feeder line rail freight paradigm for the European railways
Stanislav Božičnik, 2006, kratki znanstveni prispevek

Opis: The article deals with the development of the new paradigm of the European rail freight system predominantly suitable for the feeder lines (market niches). Taking into consideration the so far adopted legal solutions of the EU Commission for internationalisation (liberalisation) of the European railway system, the concept of the new rail freight model was developed in order to contribute to the increase of the quality, as well as to the growth of the volume of the rail freight services in Europe. Based on the findings about the disadvantages of the existing rail freight paradigm, the new solution consisting of the three interrelated and interconnected subsystems: institutional, technical/technological and organisational, is proposed. New liberalised access to the entire European rail infrastructure network will increase the competition and most probably attract new railway freight service providers. The introduction of the suggested innovative solutions in form of small, self-propelled, bi-directional train formation that can be automatically coupled and decoupled and equipped with the innovative loading and unloading equipment (enabling loading/unloading operations wherever the truck can stay parallel to the train), is to be expected predominantly on the feeder lines (market niches) of the European railways.

RELATIONSHIP BETWEEN KNOWLEDGE MANAGEMENT INFORMATION SOLUTIONS AND HUMAN RESOURCE MANAGEMENT IN IT COMPANIES
Jelena Horvat, 2015, doktorska disertacija

Opis: Knowledge has been recognized as currency for organizational sustenance and competitive advantage and is the most prominent among traditional factors of production, such as land, labour and capital. Human resource management (HRM) includes decisions that affect the success of business, all with aim of achieving long-term goals. This thesis supports the premise of relationship between HRM and knowledge management (KM) with focus on information solutions and aims to elaborate on this link from the aspect of ICT companies. Four major parts in this thesis can be distinguished: first three concern the literature analysis of current findings and fourth part covers methodology, data analysis and conclusion. In the first part, current literature findings in the field of human resource management, its functions, applications, IT systems and previous research from Slovenia and Croatia are presented. HRM is observed through HRM functions (recruitment and selection; training and development; performance appraisal). In addition to functions, various research has been done in the field of best practices, which lead to enhancement of HR. These HR best practices are considered as important factors for successful knowledge management development. This thesis tries to present and comprehend the best practises of HRM through literature analysis and classification. Second part of the literature analysis concerns the knowledge management processes, systems and mechanisms, which are explained and supported with current research results. In the third part, findings on the relationship between HRM and KM are analysed providing a conceptual model for empirical research. This doctoral thesis focuses on two aims: the analysis of previous research findings in two perspective fields (human resource management and knowledge management) and developing and testing a conceptual model that would explain the relationship between them. Achieving these aims required a comprehensive preliminary research; involvement of experts in the field of HRM and a whole set of recent statistical techniques and findings to be applied for data analysis and interpretation. Three main hypotheses and a conceptual model regarding KM and HRM were formed based on literature findings. A total of 274 completed responses were received from companies. For data analysis and hypothesis software tool the SmartPLS is used. In ICT companies and IT departments in Slovenia and Croatia, the relationship between HRM functions and effective factors with knowledge management and information solutions is analysed. Data analysis showed that in most case there is not a large difference between Slovenian and Croatian companies when it comes to HRM functions and KM solutions. One of the major contributions is the analysis of literature evidence and providing new classification and categorization of the HRM best practice. Accordingly, after literature analysis, indicators of the HR best practice were categorized into two effective factors: Work design structures (sub-factors: Design of Work and Design of relationship) and Encouraging and opportunity structures. Second contribution are the hypothesis testing through which relationship between effective factor and knowledge management, and HRM functions, information solutions and knowledge management was analyzed. Data for this thesis was collected through online questionnaire administered to ICT companies in Slovenia and Croatia. This dissertation systemizes current literature findings in two perspective field and it offers an inside in the ICT companies form Slovenia and Croatia. Due to the fact that such research has not yet been done in Slovenia and Croatian nor systematization and classifications of best practices has been provided, this dissertation contributes to the field of human research management and knowledge management through theoretical and empirical findings.
