Abstract: This paper summarizes on-going work on 3D sensing and imaging for unmanned aerial vehicles UAV carried laser sensors. We study sensor concepts, UAVs suitable for carrying the sensors, and signal processing for mapping and target detection applications. We also perform user studies together with the Swedish armed forces, to evaluate usage in their mission cycle and interviews to clarify how to present data. Two ladar sensor concepts for mounting in UAV are studied. The discussion is based on known performance in commercial ladar systems today and predicted performance in future UAV applications. The small UAV is equipped with a short-range scanning ladar. The system is aimed for quick situational analysis of small areas and for documentation of a situation. The large UAV is equipped with a high-performing photon counting ladar with matrix detector. Its purpose is to support large-area surveillance, intelligence and mapping operations. Based on these sensors and their performance, signal and image processing support for data analysis is analyzed. Generated data amounts are estimated and demands on data storage capacity and data transfer is analyzed. We have tested the usage of 3D mapping together with military rangers. We tested to use 3D mapping in the planning phase and as last-minute intelligence update of the target. Feedback from these tests will be presented. We are performing interviews with various military professions, to get better understanding of how 3D data are used and interpreted. We discuss approaches of how to present data from 3D imaging sensor for a user.

Good soundness is a result of good health care and lifestyle. How can medicaments hels up? Today the assortment you can order from online pharmacy is real high. For example Antabuse is used in given men with chronic alcoholism. Creates an distasteful reaction when drinking alcohol, which reduces the desire to drink. Cialis is a prescription drug used to treat impotence. If you’re concerned about erectile disease, you perhaps know about canadian pharmacy cialis 20mg and . Where you can get more information about ? (Read more ). At present more than half of men aged over 50 reported some degree of erectile dysfunctions. A medical review found that about 14 percent of patients grab Zyban reported sexual dysfunction. If you choose to order remedies like Cialis online, always visit your sex physician before do it. Very likely your physician will take into account possible remedy interactions with Cialis, your age and any previous experiment you have had with the therapy.

Security Link Yearly Report 2014 now available

The Security Link Yearly Report 2014 is the first of its kind. It describes the accomplishments of Security Link during 2014.

The highlights in short:

  • Security Link partners have attracted external funding for 89 different research projects. Of these, 44 were funded by the EU framework program.
  • During 2014, 62 scientific peer ‐ reviewed publications in refereed journals, 73 peer ‐ reviewed conference papers and 42 other scientific publications connected to Security Link were published.
  • The yearly Security Linkworkshop took place 20 November 2014 in Linköping.
  • Since January 2014, the multidisciplinary graduate school Forum Securitatis has been a permanent part of Security Link and is managed and financed by the Swedish Defence Research Agency (FOI) and Linköping University (LiU). During 2014, a total of 18 PhD students have been enrolled in the graduate school and a total of 2 doctoral degrees have been obtained.
  • During 2014, the five funding organizations VR, VINNOVA, Forte, FORMAS and Energimyndigheten, have on behalf of the Swedish Government, conducted and evaluation of the Strategic Research Areas, including Security Link, to determine the future financing of the strategic research areas. The result from the evaluation is expected during 2015.

20 Million SEK to CARER-The Center for Advanced Research in Emergency Response

CARER-The Center for Advanced Research in Emergency Response, has received funding with 20 Million SEK from the Swedish Civil Contingencies Agency (Myndigheten för samhällskydd och beredskap, MSB) to perform research focusing on effective emergency response.

How can the emergency response with accidents be strengthened in the future?

These are some of the issues that will be studied in a new research initiative funded by the MSB for 20 Million SEK over five years.

Researchers at Linköping University have been commissioned to build a new research environment in the field “Effective emergency response to future incident site”.

“We believe that the evolution towards a more dynamic and flexible approach in how rescue and relief resources are organized and alerted to accidents, and we also believe that it is increasingly common to use players outside the professional emergency services,” says Sofie Pilemalm, professor and director of the Research Centre CARER at Linköping University.

The work will be conducted in collaboration with rescue actors of various kinds, SOS Alarm, municipalities, government agencies and others. By developing new practice-oriented knowledge in this area, society can both save lives and reduce the damage to people, property and infrastructure. The research is expected to start in the autumn of 2015.

Docent lecture: Dr. Gustaf Hendeby

On 21 May, Security Link researcher Gustaf Hendeby presented his docent lecture with the title ‘Sensorfusion: från mätning till lägesbild’. Abstract below (only in Swedish).

Abstract: Att ha en bra lägesbild är en förutsättning för många funktioner som idag tas för givna men som för bara några decennier sedan var ren science fiction. En drivande faktor som gjort detta möjligt är den snabba utvecklingen av teknik som har gett oss allt snabbare och bättre datorer samt billigare och bättre sensorer som nu finns nästan
överallt. En minst lika viktig faktor är utvecklingen inom sensorfusion som gör det möjligt att hantera alla mätningar för att leverera en lägesbild. Sensorfusion studeras därför närmare här.

Automatiska fordonsfunktioner eller ett behov av att förstå interaktionen mellan en användare och dennes omgivning är bara två exempel på tillfällen då en bra lägesbild ger ett mervärde. En lägesbild kan ses som ett tillstånd för ett systems som skattas med tillgängliga sensorer, t ex kameror och/eller tröghetssensorer (IMUer). Genom att definiera det underliggande tillståndsskattingsproblemet matematiskt fås ett kraftfullt verktyg för att hitta en lösning. I det linjära gaussiska fallet leder det fram till det optimala kalmanfiltret. För olinjära problem krävs
approximationer. Två metoder baserade på kalmanfiltret förs fram och ett mindre känt men relevant samband presenteras. Partikelfiltret är ett kraftfullt men beräkningstungt alternativ som inte är baserat på kalmanfiltret. Genom att utnyttja modell- och metodkunskap kan partikelfiltret ändå göras till ett attraktivt alternativ för t ex
positionerings- och navigationstillämpningar. Avslutningsvis berörs alternativa ansatser till lösningar av skattningsproblemet och hur det går att bedöma om tillräckligt bra lösningar existerar. Sammantaget visar det att t ex drömmen om helt autonoma fordon inte ligger så långt bort som man kan tro utan att det går att komma en bra bit på
vägen redan med dagens teknik.
