Summary form only given. Resonant tunneling based devices are an intriguing set of devices with promising high speed, low power and high functionality capabilities. We have developed an technology to embed metallic features on the nm-scale inside a semiconductor. By combining such metallic features and heterostructures we have developed a new type of tunneling transistor, the so called Resonant Tu
We investigate the performance of concatenated coding schemes based on Faster Than Nyquist(FTN) signaling over the AWGN channel. We test both serial and parallel concatenations. In serial concatenation the FTN signaling is considered as the inner encoder and the outer code is a rate b/c convolutional code. In parallel schemes we use two parallel Gaussian channels and transmit FTN pulse trains in b
Machining is an important and widely spread manufacturing method which should not be neglected while striving towards sustainable production. Several previous articles have discussed sustainable machining and different approaches towards reaching this goal. However, few have discussed the influence of the cutting tool utilization on the sustainability during machining. This article presents a nove
Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. This accumulation procedure takes from a few hours to several days, dependin
This paper seeks to provide an overview of how companies assess and manage security risks in practice. For this purpose we referred to data of security surveys to examine the scope of risk analysis and to identify involved entities in this process. Our analysis shows a continuous focus on data system security rather than on real world organizational context as well as a prevalent involvement of to
Popular Abstract in Swedish Förståelsen av klimatets naturliga variation och dess förändring i regional skala är av grundläggande betydelse för planering och skötsel av ett hållbart samhälle. Nederbörden är en av huvudkomponenterna i den hydrologiska cykeln och har betydande inverkan på såväl vattentillgång som risker för tex översvämningar. I framtiden förväntas nederbördsmängderna öka i norra EuThis thesis focusses on the spatial distribution of precipitation within Scania and on its relation with large-scale climate. The spatial distribution of Scanian precipitation was analysed using a dense rain-gauge network of daily measurements. The performance of the Rossby Centre regional Atmospheric model in simulating the observed spatial distribution was evaluated. The influence of the regiona
The explosive popularization of personal computers during the last decade, along with the appearance of the World Wide Web and of high-level programming techniques, has opened many new and exciting opportunities in the field of education. In this chapter, a review of existing types of multimedia material used in education and of some of the authoring tools used in the production of this material i
Oldtidens og middelalderens litteratur – i skandinaviske oversættelser är en bibliografi över översättningar till danska, norska och svenska av de antika och medeltida litteraturerna. Den har som ambition att samla samtliga översättningar tryckta efter 1500 av grekisk, romersk, och övrig europeisk litteratur skriven före 1500, tillsvidare med undantag för bibliska texter. I sin nuvarande form tä
