Uppsatsen undersöker vilka förändringar som har skett i stadsplaneringen i en utvald svensk stad under 1970- och 1980-talen till dagens datum år 2017 ur ett genusperspektiv. Staden som är vald är Varberg, Halland. Studien har gjorts genom att undersöka kartor och intervjupersoner som arbetat med stadsplanering i Varberg under 1970- och 1980-talen, samt personer som arbetar med det idag. Studien är en kvalitativ studie med inriktning på ostrukturerade intervjuer. Följande var mina frågeställningar:• På vilket sätt har stadsbilden förändrats genom årtiondena i Varberg?• Hur har de manliga och kvinnliga rörelsemönster sett ut i Varberg?• Vad är de största skillnaderna på dagens översiktsplanering och den från 1978?Studien visar att rörelsemönster är ständigt skiftande och att Varberg som stad har blivit större än vad som estimerades på 1970-talet. Under 1970-talet var Varberg en industristad, idag kan den snarare benämnas som en turiststad, där turismen har ett starkt fäste och är en stor del av näringslivet. Fler kvinnor har välkomnats in i planeringsrummet och staden har ett annat fokus på utveckling idag. Framförallt för mål mer konkretiserad, skola och utbildning har större plats i översiktsplanering. Det manliga och kvinnliga rörelsemönstret har skilt sig åt, då industrin funnits i nord och skolor, vård och affärer i söder. Staden har utvecklats för att bibehålla en stadskärna och inte utlokalisera detaljhandel och därmed öppna upp för att oavsett vem du är ska ha nära till centrum.

Magistro darbo tyrimo tema – vadybinės veiklos vertinimas laiko vadybos aspektu. Baigiamojo darbo teorinėje dalyje išnagrinėta laiko valdymo problemų analizė F. Tayloro mokslinuose darbuose. Aprašyta neefektyvaus laiko valdymo problemų mastas ir galimos pasekmės. Laiko planavimo priemonės, bei potencialios vidinės ir išorinės aplinkos įtakojimas laiko praradimo priežastims. Praktinėje baigiamojo darbo dalyje nagrinėjama vadovų ir vadybininkų veiklos rezultatai apie tai, kas yra statybinėse įmonėse laiko valdymas, jo reikšmė, ką jis duoda, jo formavimo veiksniai. Tyrimo metu nustatyta, kad tiek statybinių įmonių vadovai, tiek vadybininkai supranta laiko valdymo reikmę statybinėse organizacijose, taip pat suvokia laiko valdymo svarbą. Paskutinėje magistro darbo dalyje yra pateikiamos išvados, kurios išryškina esminius darbo klausimus, taip pat pateikiamos rekomendacijos. Mūsų magistriniame darbe norime parodyti, ką šia tema rašo teoretikai, palyginti skirtingas autorių nuomones. Taip pat bandėme pažiūrėti ką apie statybinių įmonių laiko valdymą mano patys vadovai ir vadybininkai. Atlikus mokslinės literatūros analizę, nustatyta, jog vieningos ir visa apimančios įmonių laiko valdymo sąvokos nėra. Bet vis dažniau laiko valdymas yra apibrėžiamas, kaip idėjų, jausmų, suvokimų ir įsivaizdavimų, kuriuos asmuo ar jų grupė turi įmonių atžvilgiu, visuma, jai turi įtakos materialūs ir nematerialūs organizaciniai elementai, komunikacija bei asmeninės ir socialinės vertybės. / The title of Masters thesis research is „The valuation of Management activity in time management aspect“.

The worst scenario of drilling operation is blowout which is uncontrolled flow of formation fluid into the wellbore. Blowouts result in environmental damage with potential risk of injuries and fatalities. Although not all blowouts result in disaster, outcomes of blowouts are unknown and should be studied before starting an operation. Plans should be available to prevent blowouts or provide safe and secure ways of controlling the well before the drilling operation starts. The plan should include procedures in case of any blowout incident as a proactive measure. A few commercial softwares are available in the industry for dynamic kill and transient modeling. All models are proprietary and very complex which reduces the flexibility of the program for specific cases. The purpose of this study is to develop a pseudo transient hydraulic simulator for dynamic kill operations. The idea and concept is to consider the flow of each phase as a single phase flow. The summation of hydrostatic and frictional pressure of each phase determines the bottomhole pressure during the dynamic kill operation. The simulator should be versatile and capable of handling special cases that may encounter during blowouts. Some of the main features of the proposed dynamic kill simulator include; quick and robust simulation, fluid properties are corrected for pressure and temperature, sensitivity analysis can be performed through slide bars, and capable of handling variety of wellbore trajectories. The results from the proposed simulator were compared to the result of commercial software, OLGA ABC. The results were in agreement with each other. It is recommended to apply the simulator for operations with required kill fluid volumes of one to two wellbore volumes.

The challenges that face MNPCs in making healthcare more affordable is a topic that is being increasingly researched. These companies face challenges such as pressure from governments around the world to lower their prices, stagnant growth in developed markets and the failing blockbuster business model. Turning to new markets, such as emerging markets, for growth will necessitate innovations in their business models. The aim of this research was to understand what business models will work in low-income patient markets, specifically in the South African base of the pyramid context. The investigation of four MNPCs through a case study methodology, allowed the exploration of their current business models and ambidexterity level. Two of the four MNPCs exhibited a purely exploitative business model and as such had very little penetration into the BOP segment. One of the four MNPCs demonstrated a few characteristics of ambidexterity, but applied mainly an exploitative model and had limited access to the BOP segment. One of the four companies implemented all of the characteristics of business models that are successful in entering BOP markets as well as a high level of correlation to the characteristics of ambidexterity. The result of this MNPC described was a successful entrance in the BOP segment. The review of the literature and the findings of this research show that MNPCs can adopt profitable business models to enter low-income markets that not only serve consumers at the base of the pyramid but also provide sustained business benefits to the MNPCs. The research study successfully achieved the research objectives and provides insights to stakeholders as to which strategies are effective when entering a low-income patient market and what are the elements that are missing from business models that are not successful. The research also highlighted institutional voids and barriers that are unique to the South African state health care system. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Stepped hull forms are hulls with a vertical step in the hull bottom to improve performance at top speed. Stepped hulls are well documented anecdotally and scientifically to improve calm water performance at high speeds, but commonly demonstrate dangerous and unexpected dynamic instabilities during initial trials. These hulls also operate practically in waves, but their performance characteristics in waves are not well understood and rarely evaluated prior to full scale trials. To expand the scientific understanding of stepped hull performance, a systematic set of experiments and Reynolds Averaged Navier Stokes (RANS) computational fluid dynamics (CFD) simulations are used to evaluate the calm water performance, dynamic stability, and regular head wave response of two stepped hull models. Calm water experiments on two stepped hull models at varying displacement, longitudinal center of gravity location and forward speed offer data which can be used in the design to interpolate hull performance throughout expected operating conditions. CFD simulations in calm water are validated using the experimental results and numerical modeling approaches for stepped hull simulations are recommended. The calm water dynamic stability of both stepped hulls is investigated experimentally and numerically and procedures to evaluate the dynamic stability using both approaches are recommended. The performance of both stepped hulls in regular head waves is studied through experiments, which are used to validate CFD simulations of the hull in regular waves. System identification is used on five calm water CFD simulations to identify a reduced order model for the prediction of stepped hull response in waves. / Doctor of Philosophy / Boats designed specifically for high-speed operations, like military patrol craft, can often achieve higher top speeds when small vertical steps are added to the bottom of the hull. When a step is introduced, the back portion of the hull bottom is raised above the forward portion of the hull bottom to allow air underneath the hull at high speeds. When designed properly, a stepped hull can be safely operated by experienced and unexperienced users at higher speeds than conventional hulls. However, when the steps are not designed well a boat can be dangerous to operate, suffering from unexpected phenomena like end swapping (where the boat violently rotates from bow to stern) when beginning a turn. Unfortunately, it is currently difficult to predict how a stepped hull will behave during the early stages of the design. Builders often rely on full-scale prototype trials to assess the performance and safety of their designs, which is an expensive process. In this work, experimental tests (on small scale models) and computer simulations were performed on two stepped hull models in calm water and in waves to establish techniques to predict performance and safety without a full-scale prototype. The experiments were used to compare the performance of two geometries and assess the accuracy of computer simulation predictions. The computer simulations were found to predict the stepped hull performance accurately enough to be used in design prior to prototyping. Procedures are recommended to evaluate the safety of a stepped hull through experiments and computer simulations. Evaluation of hull safety through computer simulations or experiments offers the opportunity to reduce danger to test personnel during full scale trials and minimize the need for expensive design modifications after construction of the first prototype. The performance of the two hull designs in waves were studied experimentally, through computer simulation, and through a simplified method informed by computer simulations. The development of a simplified method to evaluate stepped hull performance in waves offers the opportunity for designers to consider performance in waves earlier in the design for a lower cost than previously available.
