Inaccuracy correction of robotic grinding based on laser triangulation
Get PDFV sklopu magistrskega dela smo razvili program, s katerim smo iz oblaka točk ob pomoči podane trajektorije brušenja izračunali korigirano pot brusa, kjer so upoštevane netočnosti robota. V začetnih poglavjih so razložena teoretična ozadja robota, triangulacijskega senzorja in skeniranja, s katerimi si pomagamo pri izračunu trajektorije brušenja. V nadaljevanju sledi opis robotskega sistema in laserskega profilomera, ki sta bila uporabljena v procesu brušenja in 3D skeniranja. Tu je tudi predstavljeno, kako smo v oblaku točk zaznali utore ter korigirali trajektorijo. V rezultatih smo prikazali oblak točk izdelka pred in po obdelavi ter pripadajoč 3D model. Ugotovili smo, da nekateri parametri, kot na primer gostota točk, velikost merilnega območja in naklon normale na Z os, bistveno vplivajo na uspešno zaznavo utora. Izračunane korekcije trajektorije v povprečju odstopajo za približno 1 mm v Y in Z smeri od sprogramirane, v ekstremnih primerih pa tudi 2 mm v posameznih smereh.As part of the master’s thesis we developed a program with which we can calculate the corrected grinding path from the point cloud with the help of a given grinding trajectory, where the robot inaccuracies are taken into account. In the initial chapters we explained theoretical backgrounds of the robot, triangulation sensor and 3D scanning with which we help us calculate grinding trajectory. Following this we describe robot system and laser profilometer that we used in the grinding and scanning process. Here we also present how we detected grooves in the point cloud and how we corrected the trajectory. In the results, we showed how point cloud of the product looks before and after processing and the associated 3D model. We found out that some parameters, such as the density of the points, the size of the region of interest, and the inclination of the normal to the Z axis significantly, affect the successful detection of the groove. The calculated trajectory corrections deviate on average by about 1 mm in the Y and Z directions from the programmed one, and in extreme cases by 2 mm in the individual directions
Radiologic technologists and empathy - literature review
No full textUvod: Empatija je kompleksen, dinamičen in večplasten pojem. Je sposobnost razumevanja izkušnje druge osebe. Gre za pomembno komunikacijsko veščino, ki jo opisujemo v treh razsežnostih: čustvena, kognitivna ter vedenjska empatija. Empatija je ključna za uspešne socialne interakcije, kajti omogoča medsebojno razumevanje, učenje iz dejanj drugih ter na koncu nudenje pomoči sočloveku. Namen: Namen diplomskega dela je bil predstavitev pojma empatije v poklicu radiološkega inženirja. Raziskovali smo, zakaj je empatija pomembna komponenta radiološkega inženirja, kakšen je pozitiven vpliv empatije na paciente in radiološke inženirje, kakšen je negativen vpliv empatije na inženirje radiološke tehnologije, kako empatijo vpeljati v delo ter kaj vpliva na izražanje oz. ne izražanje empatije v radiološkem poklicu. Metode dela: Uporabili smo sistematičen pregled literature, kjer smo poiskali domačo in tujo literaturo po podatkovnih bazah: Mendeley, ScienceDirect, RUL, PubMed in ResearchGate. Iskali smo po ključnih besedah: empatija, emocionalno delo, radiološki inženir, empathy, radiographer, radiologic technologist, burnout in radiography. Vključili smo članke, izdane od leta 1991 naprej. Za vključitvene kriterije smo izbrali članke v slovenskem in angleškem jeziku, katerih besedilo je dostopno v celoti. Rezultati: V analizo smo vključili 13 člankov, razvrščenih v tabelo. Razvrstili smo jih glede na naslov članka, avtorja, letnico izdaje, ključne besede, namen raziskovanja ter njihove rezultate. Empatija predstavlja temeljno orodje za oblikovanje terapevtskega odnosa med radiološkimi inženirji in pacienti ter pripomore k boljši diagnostično kakovostni preiskavi. Različne raziskave so pokazale, da empatija pozitivno vpliva na terapevtske rezultate. Pozitivno vpliva tudi na radiološke inženirje, saj odnos, ki temelji na empatiji, lahko pripomore k zmanjševanju stresa in izgorelosti na delovnem mestu ter prispeva k boljši kakovosti življenja radioloških inženirjev. Po drugi strani pa lahko nenehna izpostavljenost stresnim in čustveno težkim situacijam vodi v različne čustvene in motivacijske posledice, kot sta empatična zaskrbljenost in osebna stiska. Za radiološke inženirje je pomembno, da razumejo čustva, mnenja in izkušnje pacientov, saj na podlagi tega lažje ocenijo njihove resnične potrebe, ukrepajo v skladu z njimi. Zaključek: Empatija ima pomembno vlogo pri delu radioloških inženirjev, saj doprinese k boljšemu odnosu s pacientom ter pripomore k izboljšanju diagnostične in terapevtske kakovosti preiskave.Introduction: Empathy is a complex, dynamic, and multifaceted concept. It is the ability to understand another person\u27s experience. It is an important communication skill described in three dimensions: emotional, cognitive, and behavioral empathy. Empathy is key to successful social interactions because it enables mutual understanding, learning from the actions of others, and ultimately offering help to a fellow human being. Purpose: The purpose was to present the concept of empathy in the profession of a radiographer. We researched why empathy is an important component of a radiologic technologist, the positive adn negative impact empathy has on patients and radiologic technologists, how to incorporate empathy into the work, and what affects the expression or non-expression of empathy in the radiology profession. Methods: We conducted a systematic literature search, searching domestic and foreign literature in the following databases: Mendeley, ScienceDirect, RUL, PubMed, and ResearchGate. We searched for the keywords: empatija, emocionalno delo, radiološki inženir, empathy, radiographer, radiologic technologist, burnout in radiography. We included articles published from 1991 onward. For the inclusion criteria, we selected articles in Slovenian and English with full text accessibility. Results: We included 13 articles classified in the table in the analysis. We classified them by article title, author, year of publication, keywords, research purpose, and results. Empathy is a fundamental tool for establishing a therapeutic relationship between radiographers and patients and contributes to better diagnostic quality of the examination. Several studies have shown that empathy has a positive impact on therapeutic outcomes. It also has a positive impact on radiographers, as an empathy-based attitude can help reduce stress and burnout in the workplace and improve the quality of life of radiographers. On the other hand, the constant exposure to stressful and emotionally difficult situations can lead to various emotional and motivational consequences, such as empathic concern and personal distress. It is important for radiographers to understand patients\u27 emotions, opinions, and experiences, because on this basis they can better assess their real needs and act accordingly. Conclusion: Empathy plays an important role in the work of radiographers, contributing to a better relationship with the patient and helping to improve the diagnostic and therapeutic quality of the examination

,,Raseinių tanko" istorijos klausimu
Get PDFDuring the opening days of the German-Soviet war in the area of Raseiniai, one of the largest tank battles took place. One episode of this battle is the so-called history of the tank of Raseiniai. This episode of the initial period of the war was researched by some historians, but almost all of them used the same sources. Therefore, we can find some misconstructions (e.g., that this panzer battle lasted two or even three days), and sometimes even solid authors make basic geographical mistakes.
A heavy Soviet KV tank stopped on the way to Raseiniai - Šiluva and cut contact between two combat groups of the German 6th tank division for a whole day, holding up the fast advance of the German 41st motorized corps to the east. Attempts to destroy this tank with the new 50 mm anti-tank cannon, bombardment by large caliber cannon, and the use of engineers with explosives during the night all failed. An attempt to request air support also failed, as the Luftwaffe had other, more important targets. Only after delivering one more 88 mm cannon and with the help of an imitated tank attack did the Germans succeed in destroying the Soviet heavy tank.
Describing the progression of the battle and establishing exact times and other facts became possible after reviewing archival documents (e.g., war diaries, radiograms) found in archives. But still, there are no answers to some questions.
The author hopes that this study will help to uncover more about battles in the territory of Lithuania during the first week of the war on the Eastern Front

Exploring Emptiness: An Investigation of MA and MU in My Sonic Composition Practice
No full textThe commentary investigates Japanese aesthetics of space, silence and emptiness - ma and mu - that informed my compositional practice during the research period 2012 - 2015. The portfolio comprises text compositions and sound installations in which forms of micro events and sustained events are employed. Throughout, the emphasis is on my personal engagement with, and manifestation of emptiness that concerns a particular model of listening and perception.
Chapter 1 discusses six primary research areas: ma and mu, material, text, form, listening and perception. Firstly, I introduce ma and mu by examining noh culture and Zeami's teaching of senu hima (where there is no-action) in the context of my personal approaches to music. The following subjects are then used to contextualise my PhD practice by means of examples from various composers and visual artists. Here, these particular and enigmatic concepts are explored through Japanese art as well as Western contemporary works by Alvin Lucier, Eliane Radigue and those of the Wandelweiser collective.
Part 2 provides contextual commentaries on selected compositions from the portfolio that mostly articulate my aesthetics in relation to the topics covered in Chapter 1. koso koso addresses my methodologies to investigate the essence of senu hima, followed by treow that discusses my approach to materials and the importance of space. I move on to grade two and grade two extended in order to examine text scores, and then, look into Espèces d'espaces 03 and 04 as examples of musical forms that I employ.
Finally, listening and perception are investigated through the compositions gnome and con.de.structuring. Throughout, I describe how my works explore emptiness as a result of my particular emphasis on listening over composing

No full textÉtude exploratoire de l’intelligence culturelle dans la gestion des parties prenantes en contexte de projet
Get PDFChaque projet s’inscrit dans un contexte socioculturel donné et les parties prenantes sont souvent issues de cultures différentes. C’est, conscients de cela que certains auteurs ont souligné l’influence de la dimension culturelle en management de projets (Bredillet, Yatim, & Ruiz, 2010; Hofstede, 1983; Fanta Tesgera Jetu, Riedl, & Roithmayr, 2011; Raynal & Chedru, 2009). Toutefois, la plupart des études n’ont pas mis en évidence la pertinence de l’intelligence culturelle (IC) face à la diversité culturelle. Très peu d’études ont abordé cet aspect en contexte de projet (Beck, Gregory, & Prifling, 2008; Chipulu et al., 2016; Dusseau, Tolstikov-Mast, Walls, & Bender, 2014; Kiznyte, Ciutiene, & Dechange, 2015; Konanahalli et al., 2014; Robert, Michael, & Roman, 2009). Nous n’avons trouvé aucune étude de ce genre portant spécifiquement sur la gestion des parties prenantes (GPP) en management de projets. Pourtant, si les problèmes culturels sont légion, ces derniers prennent leur source dans la diversité culturelle qui conduit souvent à des problèmes majeurs, pouvant scléroser ou favoriser considérablement la progression du projet. Pour faire face à une telle influence, les auteurs et experts préconisent l’acquisition des connaissances culturelles qui, cependant, présente une limite importante; celle relative à l’impossibilité de mémoriser et de maitriser la vaste quantité de connaissances culturelles dans une société culturellement diversifiée (Wu, 2013). Pour résoudre ce problème, le recours à l’IC constitue le meilleur rempart, puisque cette intelligence repose sur une dialectique pertinente dans une situation de diversité culturelle. L’IC se conçoit comme « une approche holistique de la gestion des différences culturelles en évaluant comment l'individu se comporte et comment il/elle doit se comporter dans des situations culturellement diverses en général, au lieu d'apprendre à connaître certaines cultures spécifiques en détail » (Kiznyte et al., 2015, p. 12). Cela pourrait bien contribuer à pallier les différents problèmes culturels que l’on rencontre dans le cadre des projets, et en l’occurrence dans celui de la GPP. La littérature reste passablement muette quant à la description de la manière dont l’IC se manifeste dans la GPP en gestion de projet. C’est en cela que la présente recherche trouve son originalité. Non seulement elle aborde un champ relativement nouveau, elle adopte aussi une approche novatrice. En clair, il s’agit d’une étude de cas qui examine trois évènements majeurs, en adoptant une perspective interprétativiste. Les résultats qui se dégagent montrent ceci : si l’IC se manifeste dans la gestion des parties prenantes suivant un processus qui se base sur des capacités intellectuelles des acteurs, elle aboutit à la co-construction d’une nouvelle culture dans le projet. Toutefois,cette manifestation, bien que partielle, se fait à travers le temps et suivant trois étapes itératives décrites dans un modèle que nous avons baptisé Constat-Émergence-Assimilation (CÉA). Le constat concerne les différences culturelles. Il est suivi de l’émergence d’une nouvelle culture dans le projet qui, enfin, fait l’objet d’une assimilation par les parties concernées. Ces résultats sont, cependant, beaucoup plus nuancés. Tout d’abord, nous constatons que l’absence de l’IC nuit globalement à la progression du projet ; inversement, dans la situation où cette intelligence se manifeste, nous observons un effet positif sur la progression du projet. Par ailleurs, tel qu’évoqué dans la littérature, nous pensions que la manifestation de l’IC pourrait prendre ancrage dans le désir pour les acteurs d’interagir en situation d’interculturalité et suivant les différences de cultures nationales. Pourtant, les résultats indiquent que c’est le désir d’atteindre les objectifs du projet qui pousse les acteurs à transcender les différences de cultures nationales, au profit de l’apparition d’une nouvelle culture dans le projet ; celle-ci étant co-construite par les acteurs sur le terrain. Cette nouvelle culture est, en réalité, nourrie par des emprunts aux différentes cultures nationales des acteurs du projet. Finalement, on peut voir également l’émergence de trois niveaux de gestion des parties prenantes, correspondant chacun à une unité d’analyse et à une catégorie de gestionnaires. Premièrement, nous identifions le niveau opérationnel qui est relatif au mode adopté pour le management de projet. À ce niveau, la GPP est faite par les cadres de terrain. Deuxièmement, nous avons le niveau intermédiaire qui se préoccupe de l’indemnisation des populations riveraines du projet. À cette échelle, la GPP est effectuée par les cadres intermédiaires. Troisièmement, il y a le niveau stratégique qui se rapporte à la modification de l’élément clé du contrat. Il relève de la compétence des cadres supérieurs. Ainsi, sur le plan pragmatique, les divergences observées dans la manifestation de l’IC par les gestionnaires s’expliquent par leurs appartenances aux différents niveaux de GPP. En effet, d’une part, les cadres de terrain ont recours à l’IC pour faire émerger une nouvelle culture dans le projet puisqu’ils sont sur le terrain ; d’autre part, les cadres intermédiaires et supérieurs ne font pas usage de l’IC, ils s’occupent beaucoup plus des aspects liés à la gouvernance du projet.
Each project fits into a given socio-cultural context and the stakeholders often come from different cultures. It is, aware of this that certain authors have underlined the influence of the cultural dimension in project management (Bredillet, Yatim, & Ruiz, 2010; Hofstede, 1983; Fanta Tesgera Jetu, Riedl, & Roithmayr, 2011; Raynal & Chedru, 2009). However, most studies have failed to highlight the relevance of cultural intelligence (CI) to cultural diversity. Very few studies have addressed this aspect in a project context (Beck, Gregory, & Prifling, 2008; Chipulu et al., 2016; Dusseau, Tolstikov-Mast, Walls, & Bender, 2014; Kiznyte, Ciutiene, & Dechange, 2015 ; Konanahalli et al., 2014; Robert, Michael, & Roman, 2009). We did not find any such study dealing specifically with stakeholder management in project management. However, if the cultural problems are legion, they have their source in the cultural diversity which often leads to major problems, which can sclerotic or considerably favor the progress of the project. To cope with such influence, authors and experts advocate the acquisition of cultural knowledge which, however, has an important limitation; that of the inability to memorize and master the vast amount of cultural knowledge in a culturally diverse society (Wu, 2013). To solve this problem, recourse to CI is the best bulwark, since this intelligence is based on a dialectic that is relevant in a situation of cultural diversity. CI sees itself as « a holistic approach to managing cultural differences by assessing how the individual behaves and how he/she should behave in culturally diverse situations in general, instead of getting to know some specific cultures in detail » (Kiznyte et al., 2015, p. 12). This could well help to alleviate the various cultural problems that one encounters in the projects, and in this case in that of the GPP. The literature remains fairly silent on the description of how CI manifests itself in stakeholder management in project management. This is where the present research finds its originality. Not only does it tackle a relatively new field, it takes an innovative approach. Clearly, this is a case study that examines three major events, taking an interpretive perspective. The results that emerge show this: if CI manifests itself in the management of stakeholders following a process which is based on the intellectual capacities of the actors, it leads to the co-construction of a new culture in the project. However, this manifestation, although partial, takes place over time and following three iterative stages described in a model that we have called Constat-Émergence-Assimilation (CÉA), which is observation, emergence-Assimilation. The observation concerns cultural differences. It is followed by the emergence of a new culture in the project which, finally, is assimilated by the parties concerned. These results are, however, much more nuanced. First of all, we find that the absence of the CI generally hampers the progress of the project; conversely, in the situation where this intelligence is manifested, we observe a positive effect on the progress of the project. Moreover, as mentioned in the literature, we thought that the manifestation of CI could be anchored in the desire for actors to interact in a situation of interculturality and according to the differences of national cultures. However, the results indicate that it is the desire to achieve the objectives of the project that pushes the actors to transcend the differences of national cultures, in favor of the emergence of a new culture in the project; this being co-constructed by the actors in the field. This new culture is, in reality, nourished by borrowings from the different national cultures of the actors of the project. Finally, we can also see the emergence of three levels of stakeholder management, each corresponding to a unit of analysis and a category of managers. First, we identify the operational level which relates to the mode adopted for project management. At this level, the stakeholder management is done by the field managers. Second, we have the intermediate level which is concerned with the compensation of the populations living around the project. At this scale, stakeholder management is performed by middle managers. Third, there is the strategic level which relates to changing the key element of the contract. It is the responsibility of senior executives. Thus, on a pragmatic level, the discrepancies observed in the manifestation of CI by managers can be explained by their membership in different levels of stakeholder management. Indeed, on the one hand, field managers use CI to bring out a new culture in the project since they are in the field; on the other hand, middle and senior managers do not use CI, they are much more concerned with governance aspects of the project
