    A Critical Analysis of the Wetback Problem

    Automobilpalatset i Jönköping, ritat av byggnadsingenjör Birger Lindström, uppfördes under åren 1929-1930 och var ett av de första parkeringshusen i Sverige. Förutom parkering fanns det utställningshallar och bilförsäljning, service och bensinstation-långt före bilismen var en del av folks vardag. Efter rivningshot byggnadsminnesmärktes huset år 2001.   Idag finns andra affärsverksamheter i gatuplan, resterande våningar står relativt tomma och mycket nedgånga. Automobilpalatset ägs av kommunen och det finns för närvarande ingen plan för förändring.   Jag vill i mitt förslag addera människan till Automobilpalatset. Stadsbilden och synen på bilen har förändrats sedan 1930. Det är inte rimligt i dagens samhälle att frånta en stadskärna den potential som Automobilpalatset besitter genom att förvanska byggnaden och låta den stå mestadels tom. Det känns inte heller längre modernt att parkera bilar i ett så kallat palats. Den unika arkitektur och kontext som man hittar i byggnaden borde istället till större del  öppnas upp för allmänheten. Att få ta del av dessa fantastiska rum skulle vara en upplevelse för besökaren och möjliggöra en mer levande attraktiv stadsbild.   Gatubilden under kvällen skulle förändras av att de stora fönstren äntligen fick lysa upp av de boende vilket skulle trygga platsen såväl som synliggöra huset på ett nytt sätt. Byggnadens komplexa uppbyggnad med split-level-plan skapar speciella situationer. Flexibilitet och robusthet liksom tydliga industrifunkisvärden i struktur, rymd och materialitet präglar huset. Utmaningen ligger bland annat i den djupa huskroppens stora mörka ytor och i det att väga mellan nytt och gammalt.“Automobilpalatset” in Jönköping , designed by engineer Birger Lindstrom and built 1929-1930, was one of the first car parks in Sweden . In addition to parkingspace , there were showrooms and car sales , service and a petrol station - long before the car was a part of people's everyday lives. After threats of demolition the building was named a heritage, to be protected, in 2001.   Today, there is other business related spaces at street level , while the remaining floors are relatively empty and in very bad shape . Automobilpalatset is owned by the municipality and there is currently no plan for changes.   In my proposal I wan’t to add people to this place. Cityscape and the opinion of cars has changed since 1930. It is not reasonable in today's society to deprive a city center the potential that this buildning possesses by distorting the building and leaving it empty . It's no longer fashionable to park cars in a so-called palace. The unique architecture and context that one finds in the building ought instead to be opened up and public. To take part of this amazing place would be an experience for the visitor and allow for a more vibrant attractive cityscape. The large windows, finally lit up by residents, would change how the building is looked up-on. The building complex structures with a split-level-plan creates special situations. Flexibility and robustness as well as the industrustrial modernist values ​​in structure , space and materiality characterizes the house. The challenge in restoring it lies in the deep volume and large dark surfaces, and in balancing between new and old

    Tracking sperm whales using passive acoustics and particle filters

    Passive acoustics provides a powerful tool for marine mammal research and mitigation of the risk posed by high energy anthropogenic acoustic activities through monitoring animal positions. Animal vocalisations can be detected and utilised in poor visibility conditions and while animals are dived. Marine mammal research is often conducted on restricted financial budgets by non-government organisations and academic institutions from boats or ships towing hydrophone arrays often comprising only two elements. The arrival time-delay of the acoustic wavefront from the vocalising animals across the array aperture is computed, often using freely available software, and typically regarded as the bearing of the animal to the array. This methodology is limited as it provides no ranging information and, until a boat manoeuvre is performed, whether the animal is to the left or right of the array remains ambiguous. Methods of determining range that have been suggested either negate the fact the animal is moving, rely on robust detection of acoustic reflections, rely on accurate equipment calibration and knowledge of the animal’s orientation or require modification of hydrophone equipment. There is a clear need to develop an improved method of estimating animal position as relative bearing, range and elevation to a hydrophone array or boat based on time-delay measurements. To avoid the costs of upgrading hydrophone arrays, and potentially the size of the vessels required to tow them, a software solution is desirable. This thesis proposes that the source location be modelled as a probability density function and that the source location is estimated as the mean. This is developed into a practical method using particle filters to track sperm whales. Sperm whales are the ideal subject species for this kind of development because the high sound pressure levels of their impulsive vocalisations (up to 236 dB re 1 ?Pa) makes them relatively simple to detect. Simulation tracking results demonstrate particle filters are capable of tracking a manoeuvring target using time-delay measurements. Tracking results for real data are presented and compared to the pseudotrack reconstructed from a tag equipped with accelerometers, magnetometers, a depth sensor and an acoustic recorder placed on the subject animal. For the majority of datasets the animal is tracked to a position relatively close to the surface sighting position. Sperm whales are typically encountered in groups, therefore a viable tracking solution needs to be capable of tracking multiple animals. A multiple hypothesis tracking method is proposed and tested for associating received vocalisations with animals, whereby vocalisations are correctly associated for periods exceeding 15 minute

    Safe Sleep Education and Staff Compliance

    The purpose of this project was to evaluate compliance with the teaching and documentation of safe sleep practices within a pediatric unit. The objective was to increase the percentage of the charts of patients one year of age and younger that have documented safe sleep teaching at the level of compliance with the department policy. This change in compliance was measured by determining the percentage of patient charts having documented safe sleep teaching at the level of compliance prior to the implementation of mandatory staff education as compared to the percentage of charts with documented safe sleep teaching at the level of compliance after the quality improvement education. The current percentage of documentation compliance with the pediatric department policy on Safe Sleep Teaching is less than 40%. The goal is 100% of the charts will have documentation of safe sleep teaching each shift per department policy
