Att slå marknaden har varit ett kontroversiellt ämne inom akademin under en väldigt lång tid.Enligt EMH, en grundläggande finansteori, är det inte möjligt att “slå marknaden” under enlång tid utan att ta högre risk. Hedgefond-förvaltaren Joel Greenblatt publicerade år 2006 enformel som ska kunna prestera över marknaden till lägre risk, även långsiktigt, The MagicFormula. Denna studie utvärderar en Magic Formula-portfölj på den svenska marknaden i syfteatt undersöka om den kan generera en abnormal avkastning i perioden år 2000-2020. Dettagenomförs genom en kvantitativ analys. Resultaten visar att Magic Formula-portföljensintercept är signifikant skiljt från 0 i Fama & Frenchs trefaktormodell som inkluderar enmarknads-, storleks- och värdefaktor. Eftersom de riskpremier som testats för inte förklararavkastningen dras slutsatsen att antingen är trefaktormodellen bristfällig, eller så existerar enanomali kopplat till strategin.

In 2004 a new law that allowed the formation of 3D - real estate, ie properties that are limited in both the vertical and horizontal direction and consists of a closed volume. The introduction of 3D buildings were met good by both construction companies and individuals, but in the early years after the introduction the extent of land holdings became lower than expected. In several of the metropolitan municipalities, including Stockholm and Malmö, they plan for 3D - properties already in the plan phase, while the private sphere of the property owners have not been as active. The reason is believed to be that 3D subdivisions are considered cumbersome and complex. It is therefore relevant to examine 3D subdivisions closer since it is not used to the extent that is possible while it at the same time is forecast to become an increasingly common phenomenon. The aim of this bachelor thesis is to find common dominators for completed 3D subdivisions which separates commercial and residential premises with a focus on Stockholm. A study has been conducted on eight properties through interviews with the responsible land surveyor, property owners and exploration of each objects subdivision act. The study will answer four questions: How suitability conditions in the 3rd chapter of Real property law have been met, what factors influenced whether the residential or premises was parceled off, what requirements the property owner had about the subdivision and finally the problems that arose during the subdivision. In the information that emerged during the interviews could be observed that the consideration of the appropriateness of the terms of Real Property Law is always a judgment according to law, but that depends on the specific property and its conditions. The surveyor must make a personal assessment of whether the property meets the reasoning behind the bill about the introduction of 3D properties and assessment can therefore be different depending on the property. It is also difficult to know whether the surveyors assessments leads to properties that are appropriate and functioning since 3D properties are a relatively new phenomenon and there is no practice for the surveyors to refer their decisions to. In the study of factors that influenced the choice of a cut in the subdivision it appeared that the part that would be left was split off. When subdivisioning premises it was mainly housing associations who wanted subdivide and then sell the premises so that the association could accomplish better tax benefits. Regarding the subdivision of homes it was mainly commercial factors since it was considered better to sell a purely residential building without premises. The choice of a cut was also affected by the commercial activity carried out in the property – such as telecom stations or commercial – property owners with important installations or operating units chose to subdivide the parts of the property that the business was not dependent on. Respect the wishes of the owner clear links could been drawn between that the properties where it conducted any kind of commercial activity had greater requirements on the design of the real estate cooperation. It also showed that to the greatest possible extent it was desired to achieve independence between the subdivided parts. Finally the problems raised during the subdivision were studied and it appeared that the boundaries are considered problematic and time-consuming in a 3D subdivision. It was also difficult to determine what features would consist of easements and community premises and how the percentage figures for these would be distributed. Building Collaboration has thus also had a significant role here and is something that can be experienced problematic. / År 2004 infördes en ny lagstiftning som möjliggjorde bildande av 3D-fastigheter, det vill säga fastigheter som är begränsade i både vertikalt och horisontellt led och utgörs av en sluten volym. Införandet av 3D-fastigheter bemöttes bra hos både företag och privatpersoner men under de första åren efter införandet blev omfattningen av fastighetsbildningen lägre än den förväntade. Hos flera av storstadskommunerna, bland annat Stockholm och Malmö, planeras det för 3Dfastigheter redan vid framtagandet av nya översikts- och detaljplaner medan den privata sfären av fastighetsägare inte varit lika aktiva. Anledningen tros vara att 3D-avstyckningar anses vara krångliga och komplexa. Det är därför relevant att undersöka 3D-avstyckningar närmare då det inte används i den grad som är möjlig samtidigt som det förutspås bli ett allt vanligare fenomen. Syftet med denna kandidatuppsats är därför att finna gemensamma nämnare för genomförda 3D-avstyckningar som separerar lokaler och bostäder med fokus på Stockholm. En kvalitativ studie har genomförts på åtta stycken fastigheter genom intervjuer med ansvarig lantmätare, fastighetsägare samt undersökning av varje objekts förrättningsakter. Studien besvarar fyra frågeställningar: Hur lämplighetsvillkoren i 3:e kapitlet Fastighetsbildningslagen har blivit uppfyllda, Vilka faktorer som har påverkat huruvida lokalen eller bostäderna styckades av, Vilka önskemål hade fastighetsägaren i förrättningen samt vilka problem som uppstod under förrättningen. I den information som framkom under intervjuerna kunde det observeras att vid hänsynstagande till lämplighetsvillkoren i FBL är det alltid en bedömning enligt lag men som beror av den specifika fastigheten och dess förutsättningar. Lantmätaren måste göra en personlig bedömning huruvida fastigheten uppfyller de resonemang som propositionen bakom införandet av 3D-fastigheter för och bedömningen kan således vara olika beroende på fastighet. Det är även svårt att veta huruvida lantmätarens bedömningar leder till fastigheter som fungerar i praktiken då 3D-fastigheter är ett relativt nytt fenomen och det finns ingen praxis för dem att hänvisa sina beslut till. Vid studie av faktorer som påverkat valet av styckningsdel framgick det att den del som skulle överlåtas avstyckades. Vi avstyckning av lokaler var det främst bostadsrättsföreningar som ville avstycka och överlåta dessa för att kunna bli äkta bostadsrättsföreningar. När det gällde avstyckning av bostäder var det främst affärsmässiga faktorer då det ansågs bättre att försälja en renodlad bostadsfastighet utan lokaler. Valet av styckningsdel påverkades även av den affärsmässiga verksamhet som bedrevs i fastigheten - exempelvis telekomstationer eller handelsverksamhet – fastighetsägare med viktiga installationer eller driftenheter valde att avstycka de delar av fastigheten som verksamheten inte var beroende av. Avseende önskemål från fastighetsägaren kunde tydliga samband dras mellan att fastigheter där det bedrevs någon form av affärsmässig verksamhet hade större önskemål angående utformning av fastighetssamverkan. Det framgick även att i största möjliga mån önskades det att oberoende mellan styckningslotten (3D) och stamfastigheten (2D) uppnåddes. Till sist studerades vilka problem som uppstått under förrättningarna och där framgick det att gränsdragning anses problematiskt och tidskrävande vid en 3D-avstyckning. Det var även svårt att avgöra vilka funktioner som skulle utgöras av servitut och gemensamhetsanläggningar och hur andelstalen för dessa skulle fördelas. Fastighetssamverkan har således även här en betydande roll och är något som kan upplevas problematiskt.

Under året 2020 så kom ett av de första rättsfallen inom tredimensionell fastighetsbildning. Detta ledde till reaktioner bland de som jobbar med fastighetsbildning. Efter att en konsultfirma genomförde ett seminarium på rättsfallet så framkom det att de som jobbar med fastighetsbildning inte var nöjda med 3 kap 1a§ andra stycket i fastighetsbildningslagen även kallad finnanseringsvillkoret. De tyckte att en förändring av finansieringsvillkoret behövdes eller att finansieringsvillkoret ska tas bort helt. Detta leder till syftet med denna studie: att undersöka hur prövningen/hanteringen av finansieringsvillkoret har genomförts för att få en uppfattning om hur villkoret har hanterats fram tills nu. Studien ska även gå in djupare på varför förrättningslantmätarna som arbetar med fastighetsbildning tycker att villkoret kräver en förändring. I denna studie så har en enkätundersökning, intervjuer och studie av förrättningsakter genomförts för att besvara studiens frågeställningar. Resultatet visar att förrättningsakterna är svåra att utläsa med avseende på hur finansieringsvillkoret har hanterats eller hur djupt en prövning vid en förrättning går. Från enkäterna och intervjuerna så har ett bättre resultat funnits som visar att prövningen har varit delvis bristfällig men också att det finns flertalet situationer där förrättningslantmätaren anser att villkoret är uppfyllda utan att de prövat villkoret. Enkäten och intervjuerna har uppvisat liknande resultat som seminariet, det vill säga att de som arbetar med fastighetsbildning anser att finansieringsvillkoret behöver en förändring. Slutsatsen är att prövningen/ hanteringen av finansieringsvillkoret inte har varit helt enligt propositionen men att en förändring har skett och att prövning är mer lik propositionen idag. Samtidigt ser vi att finansieringsvillkoret troligen har varit uppfyllt i många av de förrättningar som genomförts oavsett om en utförlig prövning eller ej genomförts. Slutsatsen gällande förrättningslantmätarnas åsikt om att finnanseringsvillkortet behöver en förändring är att det som propositionen ville hindra inte varit ett problem och att det finns andra problem med tredimensionella fastigheter som bildas innan anläggning är uppförd. Så en förändring av finansieringsvillkoret kan anser de vara av vikt att titta på. / During the year 2020, one of the first lawsuits in three-dimensional property formation came. This led to reactions among those who work with property development. After a consulting firm conducted a seminar on the case, it emerged that those who work with property development were not satisfied with the first paragraph in Chapter 3. 1a§, second paragraph of the Property Development Act, also called the financing condition. They felt that a change in the financing condition was needed or that the financing condition should be removed completely. This leads to the purpose of this study: to examine how the examination / handling of the financing condition has been carried out to get an idea of ​​how the condition has been handled until now. The study will also go deeper into why the business surveyors who work with property formation think that the condition requires a change. In this study, a questionnaire survey, interviews and a study of administrative acts were conducted to answer the study's questions. The results show that the administrative documents are difficult to read with regard to how the financing condition has been handled or how deep an examination at a procedure goes. From the surveys and interviews, there has been a better result which shows that the trial has been partly deficient but also that there are several situations where the surveyor considers that the condition is met without having tried the condition. The survey and the interviews have shown similar results as the seminar, that is, those who work with property development believe that the financing condition needs a change. The conclusion is that the examination / handling of the financing condition has not been entirely in accordance with the bill, but that a change has taken place and that the examination is more similar to the proposition today. At the same time, we see that the financing condition has probably been met in many of the procedures that have been carried out, regardless of whether a detailed examination has been carried out or not. The conclusion regarding the business surveyors' opinion that the financing condition needs a change is that those whom proposition wanted to prevent have not been a problem and that there are other problems with three-dimensional property that are formed before the facility is built. So a change in the condition somehow they consider important.

One of the requirements for the next generation of power supplies for distributed power systems (DPSs) is to achieve high power density with high efficiency. In the traditional front-end converter based on the two-stage approach for high-power three-phase DPSs, the DC-link voltage coming from the power factor correction (PFC) stage penalizes the second-stage DC/DC converter. This DC/DC converter not only has to meet the characteristics demanded by the load, but also must process energy with high efficiency, high reliability, high power density and low cost. To meet these requirements, approaches such as the series connection of converters and converters that reduce the voltage stress across the main devices have been proposed. In order to improve the characteristics of these solutions, this dissertation proposes high-efficiency, high-density DC/DC converters for high-power high-voltage applications. In the first part of the dissertation, a DC/DC converter based on a three-level structure and operated with pulse width modulation (PWM) phase-shift control is proposed. This new way to operate the three-level DC/DC converter allows soft-switching operation for the main devices. Zero-voltage switching (ZVS) and zero-voltage and zero-current switching (ZVZCS) soft-switching techniques are studied, analyzed and compared in order to improve the characteristics of the proposed converter. This results in a series of ZVS and ZVZCS three-level DC/DC converters for high-power high-voltage applications. In all cases, results from 6kW prototypes operating at 100 kHz are presented. In addition, with the ultimate goal of improving the power density of the DC/DC converter, a study of several resonant DC/DC converters that can operate at higher switching frequencies is presented. From this study, a three-element ZVS three-level resonant converter for applications with wide input voltage and load variations is proposed. Experimental results at 745 kHz obtained without penalizing the efficiency of the PWM approaches are presented. The second part of the dissertation proposes a quasi-integrated AC/DC three-phase converter that aims to reduce the complexity and cost of the traditional two-stage front-end converter. This converter improves the complexity/low-efficiency tradeoff characteristics evident in the two-stage approach and previous integrated converters. The principle of operation for the converter is analyzed and verified on a 3kW experimental prototype. / Ph. D.

Thesis (M. Tech. Design technology) -- Central University of Technology, Free State, 2011 / This dissertation outlines a procedural scanning process using the portable ZCorporation ZScanner® 700 and provides an overview of the developments surrounding 3D scanning technologies; specifically their application for archiving Cultural Heritage sites and projects. The procedural scanning process is structured around the identification of 3D data recording variables applicable to the digital archiving of an art museum’s collection of sculptures. The outlining of a procedural 3D scanning environment supports the developing technology of 3D digital archiving in view of artefact preservation and interactive digital accessibility. Presented in this paper are several case studies that record 3D scanning variables such as texture, scale, surface detail, light and data conversion applicable to varied sculptural surfaces and form. Emphasis is placed on the procedural documentation and the anomalies associated with the physical object, equipment used, and the scanning environment. In support of the above, the Cultural Heritage projects that are analyzed prove that 3D portable scanning could provide digital longevity and access to previously inaccessible arenas for a diverse range of digital data archiving infrastructures. The development of 3D data acquisition via scanning, CAD modelling and 2D to 3D data file conversion technologies as well as the aesthetic effect and standards of digital archiving in terms of the artwork – viewer relationship and international practices or criterions of 3D digitizing are analysed. These projects indicate the significant use of optical 3D scanning techniques and their employ on renowned historical artefacts thus emphasizing their importance, safety and effectiveness. The aim with this research is to establish that the innovation and future implications of 3D scanning could be instrumental to future technological advancement in an interdisciplinary capacity to further data capture and processing in various Cultural Heritage diagnostic applications.

Published Article / In this paper the time and cost parameters of tooling manufacturing by metal casting in rapid prototyping sand moulds are assessed and comparison is made with alternative tool making processes such as computer numerical control machining and investment casting (Paris Process). To that end two case studies obtained from local companies were carried out. The tool manufacturing was conducted according to a five steps process chain referred to as Rapid Casting for Tooling (RCT). These steps include CAD modelling, casting simulation, rapid prototyping, metal casting and finishing operations. In particular the Rapid Prototyping (RP) step for producing the sand moulds was achieved with the aid of an EOSINT S 550 Laser Sintering machine and a Spectrum 510 Three Dimensional Printer. The results indicate that RP is the rate determining step and cost driver of the proposed tooling manufacturing technique. In addition it was found that this tool making process is faster but more expensive than machining and investment casting.

The costal populations of perch (Perca fluviatilis) in some parts of the Baltic Sea have been in decline for about two decades. Recruitment failure in the early larval stages has been put forward as a possible cause and the decline has also been suggested to coincide with increases in three-pined stickleback (Gasterosteus aculeatus) densities. The aim of this study was to study the effects of growth and survival of newly hatched perch larvae in the presence of the three-pined stickleback, and if possible determine the main mechanism behind any negative effects the perch may suffer under such conditions. Using large scale experimental ponds as a controlled habitat, an experiment was conducted where perch larvae were being exposed to sticklebacks under four different stages of their development. Results showed that the three- spine stickleback can have a strong negative effect on the survival of young perch. This effect was strongest in the earliest stage of perch development and decreased as they grew bigger. The zooplankton densities didn't differ between the controls and stickleback treatments, suggesting that the young perch didn't suffer from food limitation. Instead predation was identified as the main mechanism behind the high mortality. The results of this study highlight the potential danger of the observed patterns of decreasing predator populations in conjunction with increasing populations of smaller prey species in the Baltic Sea.

Submitted in fullfilment of the requirements of the Degree of Master of the Built Environment (Survey), Durban University of Technology, Durban, South Africa, 2015. / Surveying concepts are difficult to understand, especially when students are exposed to surveying for the first time. Surveying is best understood when linked to field applications; however, students are only exposed to surveying and related field operation procedures during practicals. Two-dimensional (2D) explanations of surveying equipment used is shown during class lectures, which makes understanding of field procedures difficult to teach and learn during normal class lectures. A new approach to lecture delivery is required to make lectures more interesting and visually stimulating via three-dimensional (3D) animated models of levelling equipment and simulation of field observations and data collection. Additionally the learning of basic surveying concepts cannot be limited to field practicals, but in conjunction with learning that takes place in the classroom. Students' ability to properly learn the correct use of surveying equipment during time-tabled practicals is limited. The students do not have sufficient time in their normal scheduled practicals to learn to use surveying equipment to the required proficiency level. The main objective of this research was to deal with these inadequacies by exposing students to (3D) animated models of surveying equipment during lectures and the corresponding field applications created within SketchUp software. Students were exposed to these animated 3D models during lectures, so that their actual field operation and application could be simulated. Quantitative analysis of the student achievement data revealed that there was a significant difference between the test scores of the control and experimental groups. Additional analysis of the developed Likert-type scale questionnaire revealed that students' had a positive attitude towards the teaching tool.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Historically, aircraft power monitoring has required the use of multiple signal conditioning functions to measure various parameters including voltage, current, frequency and phase. This information was then post processed to determine the characteristics of the 3-phase power quality on the aircraft. Recent developments in embedded DSP processors within signalconditioning systems provide the instrumentation engineer with expanded capabilities for realtime on-board power quality monitoring. Advantages include reduced space and bandwidth requirements and minimal wiring intrusion. For each phase, output data may include peak positive and negative voltages and currents, peak-to-peak, average and RMS voltages and currents, phase power (real and apparent), phase power factor, phase period (frequency), phase shift measurement from phase 1 (the reference phase) to phase 2, and from phase 1 to phase 3. In addition, a Fast Fourier Transform (FFT) is performed on each phase voltage to provide Total Harmonic Distortion measurements. This paper describes the methods employed in the implementation of these functions on a single signal-conditioning card in order to provide detailed information about the power quality of a three-phase aircraft power source.
