    Tema završnog rada je „Uvođenje postupka za analizu mjernog sustava u proizvodni proces“. Radi boljeg kontroliranja, ali i poboljšavanja proizvodnih procesa, potreban je kvalitetan mjerni sustavi koji mjeri značajke procesa. U ovom su radu opisani postupci za analizu mjernog sustava u proizvodnome procesu te je navedena matematička podloga provedenih koraka. Analiza mjernog sustava razlikuje se od slučaja do slučaja, odnosno ovisi o broju mjeritelja, broju predmeta mjerenja i broju ponavljanja mjerenja. U svrhu lakše analize mjernog sustava upotrebaljvaju se različiti računalni programi. Pri izradi ovog rada korišten je jedan takav program – Minitab 17 (probna verzija)

    Tema diplomskog rada je „Osnovni statistički alati za analizu podataka“. Rad je podijeljen na dva dijela. U prvom su dijelu opisane metode deskriptivne statistike, koja se bavi prikupljanjem, analizom i interpretacijom podataka. U području inferencijalne statistike, kod koje na temelju uzorka zaključujemo o populaciji, objašnjene su metode testiranja hipoteza. U drugom dijelu, odabrani su primjeri konkretne primjene opisanih statističkih alata te je procijenjen njihov praktički značaj. U svrhu lakše analize podataka upotrebljavaju se različiti računalni programi. Pri izradi ovog rada korišten je jedan takav program – Minitab 17 (probna verzija)

    Comparing Risk and Resilience Approaches

    Get PDF
    Ever increasing challenges in the areas of risk management have led to a need for a risk management approach which deals not only with threat prevention but also adaption, absorption and recovery from adverse events. This has led to the rise of the concept of resilience analysis and management, which, unlike risk assessment and management focuses on the overall system under analysis rather than its individual components. Therefore, both the civilian and military sector have, over the past decade, emphasized the need to clarify the concept of resilience management as well as to differentiate it from related terms such as risk management. This article aims to build upon the existing literature and provide a comparison of the risk and resilience approaches which offer ways to analyse and manage these concepts

    In-Crystal Dislocation Behaviour and Hardness Changes in the Case of Severe Plastic Deformation of Aluminium Samples

    The presence of dislocations significantly modifies the mechanical properties of crystalline solids. Severe plastic deformation (SPD) and the most used SPD process – the Equal Channel Angular Pressing (ECAP), affect the multiplication and localized accumulation of dislocations. This research is related to the observation of dislocation pile-up and significant reduction of the crystalline grain size caused by severe deformations in the ECAP process of the widely used aluminium material (Al 99.5%). Because of its lightweight, the application of Al 99.5 % can pose a challenge for the aviation and space industry, especially since its mechanical properties limit its application. Improving these mechanical properties can extend its applicability in cases of demanding constructions as well as influence the final product cost. As a confirmation of SPD in-fluence on mechanical properties, material hardness has been examined and described. Dislocation monitoring is enabled using the light and electron microscopy and AFM (Atomic Force Microscope) device. A numerical simulation of the Equal Channel Angular Pressing process using the ABAQUS software package determined the representative area of the most severe deformation

The thesis is separated into two parts. The first one shows methods of descriptive statistics, which deals with data collection, analysis and interpretation. In the inferential statistics section, hypothesis testing methods are explained. In the second part, examples of the specific application of the described statistical tools are selected and their practical significance is assessed. To facilitate data analysis, various computer programs are used. Also, in preparation for this study, one such program was used – Minitab 17 (trial)

For better control, and improvement of production processes, quality measurement system is needed to measure the characteristics of the process. This paper describes the procedures for the measurement system analysis in the manufacturing process and mathematical backgroud of implemented steps. Analysis of the measurement system is different from case to case, and depends on the number of operators, the number of measured parts and number of measurement repetitions. In order to facilitate analysis of the measurement system, various computer programs are used. Also, in preparation of this study, one such program was used – Minitab 17 (trial)
