The time-domain version of the optical theorem is discussed. The theorem relates the sum of the scattered and absorbed energies, for a plane pulse that is scattered from a bounded obstacle, to the far-field amplitude in the forward direction. Several fundamental results concerning the scattered and absorbed energies that follow from the theorem are discussed.

All-optical packet switching designs have evolved in the last years. However, all-optical packet forwarding functionalities are still limited. Several label assignation methods have been studied in order to efficiently use the small label space of the designs. In this paper, we present a novel scheme for label switched path protection for networks with small label spaces, such as all-optical packe

This paper presents results from testing of a burst detection and location technique on a water transmission pipeline. The primary targets of the method are medium and large bursts that are the result of a sudden rupture of a pipe wall or other physical element in the pipeline system. The technique is based on the continuous monitoring of the pressure in the pipeline combined with a hydraulic tran

Projektet redovisas med en beskrivning och analys av arbetet med att leda ett lärarlag som här definieras som ett community of practice (Etienne Wenger 1988) med målet att genom ett sådant kollegiearbete gemensamt utveckla ett ändamålsenligt campus ethos för våra masterstudenter (Adrianna Kezar 2007). Mina erfarenheter och reflektioner kring arbetet med att leda och skapa möjligheter för samarbete

Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. The paper discusses a pipelined implementation that supports the handling of gray-level images at 180 to 240 Mpixels per second by exploiting the Virtex-II macros to spatially unroll the local feedback.

Popular Abstract in Swedish Att balansera. Cancer från ett primärvårdsperspektiv. Diagnostik, posttraumatisk stress och vård vid livets slut Denna avhandling belyser cancer från en utgångspunkt som kanske inte handlar om vad man först kommer att tänka på när man hör ordet cancerforskning. Det handlar inte om att “lösa cancerns gåta” eller att hitta nya metoder för behandling eller diagnos. UtgångThis thesis explores cancer from a primary care perspective covering three areas: diagnosis, posttraumatic stress disorder (PTSD), and end-of-life care. We analyzed patient records of every child diagnosed with a malignancy in a defined area. During 12 years 68 children were diagnosed (incidence 14/100,000). For 68% the diagnosis was initiated in primary care. There were 25 children with leukemia

År 1905 arrangerades det första nordiska historikermötet i Lund. Mötet blev till viss del ett misslyckande eftersom norrmännen uteblev på grund av den svensk-norska unionskrisen. Några få finländare medverkade - men de hade sin politiska och historieteoretiska uppmärksamhet riktad åt andra håll. De nordatlantiska samhällena hade ännu inga akademiska historiker. Mötets öde visar hur historia och hi

Test-Driven Development (TDD) is a software development approach where test cases are written before actual development of the code in iterative cycles. Context: TDD has gained attention of many software practitioners during the last decade since it has contributed several benefits to the software development process. However, empirical evidence of its dominance in terms of internal code quality,
