A comparison of commercial scent lures in attracting Raccoon dogs (Nyctereutes procyonoides)
The invasive species raccoon dog (Nyctereutes procyonoides) is currently under establishment Sweden and it is vital to discover invading individuals to prevent colonization. The use of wildlife cameras to discover dispersing raccoon dogs have been implemented in the north-European raccoon dog management program. In this study, I test the ability of four commercially available scent lures to attract raccoon dogs to camera stations. The study was conducted in the Åland Islands where raccoon dogs are abundant and the results could improve the effectiveness of the camera stations used in the program. I used 12 sites with five camera stations in each and tested the four lures and one control with no lure in each site.
Monitoring lion movements
Prevention of lion predation towards African livestock is of great importance due to the economical losses farmers have because of this. Predation is also one of the main reasons for human-wildlife conflicts and lions often get killed because of it. Therefore, a pilot study using camera traps was conducted to monitor movements of lions and other wildlife through a wildlife corridor in Ol Pejeta Conservancy. The results were compared with a previous study that counted prints in the soil in front of the corridor. Due to theft risk the cameras had to be taken down and pictures were only collected from nine days.
Realtidsstyrning av IP-kamera
The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network. An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS.
The Surveillance Camera Players : Ett konstnärligt motstånd mot övervakningssamhället
The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group The Surveillance Camera Players. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field.

Jag redovisar skillnaden mellan 2D, 2.5D och 3D-genererade miljöer och vad som bör användas vid olika situationer. Jag rapporterar även om områdets generella utveckling samt i vilken riktning dess utveckling ser ut att gå..
Utvärdering av lockmedel för marklevande predatorer under midvintermånader i Norrbottens inland
Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used.
In this study three kinds of different lures was tested against each other?s.
Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.
Kameraövervakning : En juridisk analys
Camera surveillance can provide good protection against certain types of crime, but it can also invade our privacy. The County Administrative Board monitors compliance with the rules by visiting those places to which the general public has access. They have to issue permits before general camera surveillance to those places which the general public has access. In certain cases, in stores for example, general camera surveillance is permitted only if the Country Administrative Board is notified in advance. The Data Inspection Board is a public authority and responsible for the camera surveillance for those places to which the public not has access.
Designkoncept av ?toycam? : Framtagning av koncept för analog kamera
Analogue photography is something that many thought died out in the beginning of the 21?st century as a result of the digital revolution. But that?s not the case. As the digital revolution swept over the world a movement of analogue cameras, and so called toycams grew bigger.
Datorsystem för kvalitetskontroll och temperaturövervakning med värmekamerateknik
The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .
En övervikt av kvinnor : En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv
We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.
Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?
The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.
Fjärrstyrning av videokamera
On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.
Anlockning och gnag av snytbaggar (Hylobius sp.) : effekt av plantstorlek och behandling med metyljasmonat
Two field experiments were conducted in central Sweden in order to: 1) Determine a relationship between the number of approaching pine weevils (Hylobius sp.) and the number of attacks by pine weevils, in relation to the size of seedlings of Scots pine (Pinus sylvestris). 2) Determine if application of methyljasmonate (MJ) on seedlings of Scots pine will result in higher resistance towards attacks by pine weevils and/or have any effect on the number of approaching pine weevils. The field experiments were designed with two separate parts in close vicinity on the same clear cuttings: a) pitfall traps placed in patches of scarified soil that caught approaching pine weevils at 2.5 cm from the bait, which consisted of different sized seedlings of Scots pine some of which were subjected to application of MJ and b) the same type of seedlings planted out in patches of scarified soil.
The first field experiment was conducted on a 1-year old clear cutting outside Uppsala in east central Sweden and the trapping part of the experiment consisted of 8 blocks with 6 treatments: 1) control, 2) small over-wintered seedling, 3) medium sized seedling, 4) medium sized seedling treated with 0.5 ml 100 mmol MJ 4 days prior to start of experiment, 5) large seedling, 6) vial with 9.5 ml of ?-pinene. The trapping experiment lasted for 6 weeks in the early summer.
Narrativ i visuell media
Denna undersökning omfattar kamerans inverkan på narrativet i visuella medium. Syftet är att få en insikt i hur kunskap om kameratekniker och ?vinklar påverkar hur åskådaren uppfattar vad regissören vill förmedla, och undvika att fokus sätts på element i filmscener som riskerar att förvirra åskådaren. För att undersöka detta problemområde har litteratur om filmhistoria och kamerateknik använts för att sammanfatta kunskap om hur kameran skall användas, för att förmedla relevant information och bygga upp den effekt som regissören strävar efter. Informationen utifrån detta har därefter tjänat som utgångspunkt för att skapa en kort animerad film med rymdtema där kameran eftersträvar att leverera en konkret visuell upplevelse där vinklar används för att understryka vad varje scen vill förmedla.
