The following report deals with a new autofocus algorithm within the framework of time domain SAR processing (Fast Factorized BackProjection). The strategy, developed at SAAB EDS, relies on varying flight track parameters until a sharp image is obtained. Focus measures are provided by a predetermined object function. After a short introduction and some preliminaries, the algorithm is described ...

Rubber based forming process is a versatile metal fabrication process used in commercial aerospace, automotive and defence applications. It is well suited for prototyping and production of small quantities of sheet metal parts. Rubber based forming employs a rubber pad contained in the rigid chamber or flexible diaphragm as one tool half, requiring only one solid half to form a part to final sh...

Components (in-house or pre-fabricated) are increasingly being used to reduce the cost of software development. Given that these components may not have not been developed with dependability as a driver, the components need to be adapted to deal with errors coming from their environment. To achieve this, error containment wrappers are often added to increase the robustness of such components. A...

Kansei or Affective Engineering is a relatively new research field in the West. Linköping University in Sweden has been pioneering research and application within Kansei Engineering since 1999. Several companies have cooperated in different Kansei studies, for example Toyota/BT, Volvo, Saab, Scania. In some of the early studies, there were difficulties to apply the methodology. Reasons for this...

Ethnobotanical surveys were conducted in Gamo Gofa, Debub Omo and Kaffa; which are the three major korarima (Aframomum corrorima (Braun) P.C.M. Jansen) growing regions of southern Ethiopia. Plant parts used as a medicine for different aliments were documented. Eightythree percent of key informants replied that seeds were mostly used as traditional medicine followed by leaves (75%) and rhizomes ...

Pigmentation has become an important phenotypical characteristic, in the pharmaceutical, medicinal as well as in the cosmetic field. Plants and their extracts are inexpensive and rich resources of active compounds that can be utilized to inhibit tyrosinase activity as well as melanin production. Natural and synthetic chemical agents can frequently modulate the metabolism of pigmentation produce...

As the aesthetic aspect of a product is becoming more and more important in customers' decisions, there is an increasing need of tools able to express and preserve the styling intent during the product development cycle, while offering an interaction with the user much more adherent to his mentality. The European Project FIORES-II (Character Preservation and Modelling in Aesthetic and Engineeri...

Support for system speci cation in terms of modelling and simulation environments has become a common practice in safety-critical applications. Also, a current trend is the automatic code-generation, and integration with formal methods tools in terms of translators from a high level design { often using common intermediate languages. What is missing from current formal methods tools is a well-f...

In modern systems for air surveillance, it is important to have a high quality situation assessment. SAAB has a system for air surveillance, and in this thesis possible improvements of the tracking performance of this system are explored. The focus has been on improving the tracking of highly maneuverable targets observed with low sampling rate. To evaluate improvements of the tracking performa...
