Mechanical scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.

The purpose of this paper is to examine different methods for organisation and retrieval of pop and rock music recordings, and the problems concerned with this organisation. The focus is the question whether values towards pop and rock music influence the organisation of music in major Swedish record collections. As a background for this discussion, the study also discusses how music is organised in these collections, and what kind of problems are associated with their organisation. Also included in the paper is a minor investigation of how problems with the organisation of pop and rock music are dealt with in library and information science, and how values towards pop and rock music are dealt with in society in general. The main focus of the study, however, is an empirical study of how values towards pop and rock music manifest themselves in the pop and rock organisation of six Swedish institutions with major collections of music recordings.

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.

Rock singing - five vocal teachers´ experience of the female voice.The purpose of this study is to find out what different vocal teachers have to say about rock singing and the female singing voice. The method I have used to gather information is a phenomenographically inspired qualitative interview. The study begins with a few thoughts about my interest in rock singing, followed by a short overview about other research and literature that has been published on the subject. I have interviewed five vocal teachers in this study. All of them with many years experience of singing, both singing themselves and teaching professionally.

In this paper I discuss the theory of altered states of consciousness. Some of the rock art of the san-people in southern Africa and the lakota people in South Dakota, USA have been inspired by experiences during trance. The question is if some of the rock art in southern Scandinavia also have been inspired by trance experiences, and if archaeological scientists by investigating this theoretical view might find a better understanding as far as the Bronze Age in Southern Scandinavia is concerned..

Divisionen Underground Rock Excavation på Atlas Copco tillverkar kundanpassade gruvmaskiner i världsklass till kunder i mer än 170 länder. Från inköpsperspektivet är majoriteten av leverantörerna svenska men de dyraste komponenterna köps in från utlandet. Detta gör att stora krav ställs på både logistiken och produktionssystemet. De senaste årens ökande efterfrågan har lett till att materialförsörjningen har svårt att hantera de volymer som krävs och till följd uppstår störningar. En effektivisering och kapacitetsökning är nödvändig och därför kommer detta examensarbete att handla om kartläggning av material- och informationsflöde samt bristidentifiering av störningar i materialflödet.

Lately, more and more music festivals have emerged in Sweden. People?s desire and need to visit these events only seems to increase. Cultural tourism and music tourism has developed into a significant and important part of the experience industry and it employs more and more people within the tourism industry. The purpose of this paper is to investigate which effects this can have on the local community.

During the 1920?s the town of Bollnäs had the ambition to expand. The expansion included a merger with Björkhamre and the colonization of unused areas, e.g. the area around Onbacken. The archaeologist Gustaf Hallström came to Bollnäs to investigate an ancient tomb located on Onbacken.

The survey takes its starting point in a critical evaluation of recent phenomenological approaches to rock art in landscape studies, foremost the works of Chris Tilley. The purpose is to present a phenomenological theory, based on the philosophy of Maurice Merleau-Ponty, which includes both motives, places and landscapes in a holistic interpretation. Bronze age rock art around Motala ström and the city of Norrköping is used to exemplify the theoretical discussion. When presenting the framework, emphasis is being laid on the bodily experience of rock art and place through the process of phenomenological intersubjectivity..

The purpose of this thesis is to do an inventory of Swedish Bronze Age rock carvings depicting intercourse, and other sexual acts; applying gender traits on these in order to get a glimpse of what kind of normative outlook people at this time had upon sexuality. .

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

In this paper I will attempt to recreate a prehistoric landscape surrounding the rock carving site of Släbro at Nyköping in Södermanlands län by using GIS. The main focus area is the river valley at Släbro and the six panels with rock carvings that have been dated to the Bronze Age. I?ll attempt to shed light on a long lost landscape. The shore line displacement have been extensive in this area a reconstruction will visualize the relationship between the panels, and their relationship to the surrounding landscape.

Examensarbetet har utförts på Atlas Copco Rock Drills AB i Örebro i divisionen Underground Rock Excavation (URE). På URE i Örebro bedrivs tillverkning av underjordsmaskiner för gruv- och tunnelindustrin. En del av dessa maskiner är så kallade bergsförstärkningsriggar vars funktion är att säkra upp berg i gruvor och tunnlar.Uppgiften för arbetet var att undersöka cementsystemet på en av dessa riggar, kabelbultningsriggen Cabletec LC.Målet var att ta fram nya förslag på förbättringar och efterföljande experiment, gällande riggens cementsystem som ska leda till en ökad tillgänglighet av Cabletec LC.Arbetet inleddes med att ställa upp frågeställningar som skulle behöva besvaras och åtgärder för att få svar på dessa utformades. Dessa frågeställningar utgjorde grunden till planeringen av arbetet. Aktiviteter som utfördes utifrån frågeställningarna var analys av dagens system, litterär studie, kundbesök, intervjuer med konstruktörer, idégenerering och utvärdering.Studien av maskinen visade att det fanns flera problem med cementsystemet, framförallt med pumpning, blandning och renhållning.
