BCJR based source coding of image residuals is investigated. From a trellis representation of the residual, a joint source-channel coding system is formed. Then the BCJR algorithm is applied to find the MAP encoding. MAP and minimized squared error encoding are compared. The novelty of this work is the use of the BCJR algorithm and the MAP criterion in the source coding procedure. The source encod
Äter folk fortfarande lutfisk? Varför smyckar så många sina trädgårdar och balkonger med ett överdåd av elekriskt ljus? Vem vill ha nakna tomtar och röda underkläder? Ett fyrtiotal forskare, verksamma vid arkiv, museer och universitetsinstitutioner med etnologisk och kulturvetenskaplig inriktning, ger här inblickar i vår tids jul i Sverige. Utgångspunkten är ett dokumentationsprojekt kring den nut
This paper presents the preliminary evaluation of different powered-wheelchair control modes for individuals with severe motor impediments. To this end, a C400 Permobil wheelchair has been updated with a control command communication interface and equipped with a scanning laser sensor to carry out the automation algorithms that are part of the robot operating system framework. A pilot test was per
Abstract in UndeterminedIn recent years, there has been a marked proliferation in the literature on economic approaches to ecosystem management, which has created a subsequent need for real understanding of the scope and the limits of the economic approaches to ecosystems and biodiversity. Within this Handbook, carefully commissioned original contributions from acknowledged experts in the field ad
This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. Axial heterostructures in the form of quantum dots (QDs) in the nanowires as well as radial heterostructures in the form of core-shell nanowires were studied. Axial

This paper claims that case is vP-internally interpretable and that high NP-movement is driven by (minimally) two other ‘forces’: Person checking in a position higher than Tense, and EPP (Fin) checking in a still higher position, ‘Spec,IP’. This is evidenced by ´low’ nominatives, quirky agreement, Stylistic Fronting and expletive-distribution. Another central claim of the paper is that grammar int
When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat
We report on the interfacial behaviour of a series of nonionic diblock copolymers at solid hydrophobic and hydrophilic surfaces/water and silicone oil/water interfaces, studied by ellipsometry. The polymers consist of a hydrophobic C-18 chain linked to a hydrophilic poly(ethylene oxide) (PEO), block varying from 50 to 250 U. The adsorption of these copolymers at low bulk concentrations was found t
Most methods that guide the designer through the later phases of the design process are general in nature, and it is up to the designer to organize the design work using the tools and techniques available. This process also relies greatly on experience, which is quite a challenge for students, who are mostly novices in the area. In a comparative study, the evolution of the experience and skills ac
