The electrical properties of ZrO2 and HfO2 gate dielectrics on n-InAs were evaluated. Particularly, an in situ surface treatment method including cyclic nitrogen plasma and trimethylaluminum pulses was used to improve the quality of the high-κ oxides. The quality of the InAs-oxide interface was evaluated with a full equivalent circuit model developed for narrow band gap metal-oxide-semiconductor (
This article examines the relationship between theories of the ‘new’ public diplomacy and recent attemptsby foreign ministries in the United Kingdom, United States and Sweden to develop public diplomacystrategies for the early twenty-first century. It provides a summary of policy debates in each nation alongsideanalysis of the evaluation methods that have been designed to support them. The article
A variety of alkyl and aryl glycosides were investigated as substrates for almond β-glucosidase catalysed synthesis of hexyl-β-D-glycosides in low aqueous hexanol media. The rate-limiting step in the organic media was determined to be the glycosylation of the enzyme. The kinetic constants V max , K m (glycosyl donor) and V max /K m were all influenced by the water activity and they all increased
Pseudo-random functions are a fundamental building block in many cryptographic applications. In certain scenarios, a weaker notion (where security is restricted to uniformly random input), but more computationally efficient, called weak pseudo-random functions, is sufficient. In this work, we present new differential attacks on the main binary weak pseudo-random function constructions, namely the
Organizations that manufacture high volumes of complex products (e.g., pharmaceutical, automotive, food) require specific strategies to ensure efficient processing of parts and a sustainable level of inventory by waste minimization. A review of literature sources revealed how inventory is classified and managed amongst organizations and industries and key challenges that current organizations face
BackgroundAnimal bedding remains an underutilized source of raw material for bioethanol production, despite the economic and environmental benefits of its use. Further research concerning the optimization of the production process is needed, as previously tested pretreatment methods have not increased the conversion efficiency to the levels necessary for commercialization of the process.ResultsWe
Nanowire (NW) Photovoltaics are a promising route for low-cost multi-bandgap tandem cells, which is taxing in terms of processing and lattice matching in traditional planar geometries.[1] III-V nanowires are more suitable for monolithic integration as they can assimilate the lattice mismatch to a larger extent.[2] GaAsP is a material that offers a wide tunability of the band gap from near infrared
In this paper, an investigation is done into the potential of increasing the coolant temperature of an engine to maximize the powertrain efficiency. The study takes a holistic approach by trying to optimise the combined engine and waste heat recovery system. The work was done experimentally on a Volvo 4-cylinder light duty diesel engine in combination with Rankine cycle simulations. For the study,
This thesis aims to provide a suggestion to how a chair could be designed to have less negative impact on the environment. At many offices the turnover of furniture is big. By conducting interviews and study visits, it was indicated that chairs used in lunch areas and meeting rooms are the type of furniture that gets exchanged the most in office environments. Many of the existing chairs used for t
Swedish fire and rescue services are in a transformation that shifts towards an increased focus on preventive actions as well as more strategic oriented activities within the organizations. To support and develop such types of activities, Geographical Information System (GIS) could be an effective tool to manage and analyze geographic data. This thesis aims to examine the prerequisites for develop
Beginning with the question of whether, and how, gender equality can be measured, this thesis is written with the ambition to evaluate one aspect of the Swedish government’s equality goal, equality in power and influence, with the help of an index. It departs from a discussion within the field of gender studies where gender equality is found to be an “empty” word that can be used for a variety of
The C99 standard for the C programming language introduced the new type qualifier restrict which acts as a hint for the compiler and the programmer that the specified pointer is not aliased by any other pointer if the pointed object can be modified. By using restrict on pointers the compiler may, if implemented and allowed, optimize code even further. This thesis investigates how well the C compil
Recently, major infrastructure projects have been started in Denmark and this research tries to answer how social aspects are investigated in planning and analysis work before the big projects are constructed. The research has interviewed representative from the Copenhagen Metro Company and Danish Road Directory to uncover the analysis work and how social aspects are included in their work. The re
