Realization of a matching region between a radome and a ground plane

In order to reduce the monostatic signature of the junction between a radome and the metallic structure to which it is attached, a tapered resistive sheet can be used. In this paper, we describe an easy method to realize this tapering using geometric variations on a subwavelength scale, with a significant reduction of the number of processing steps as a result.

The mechanism of protein kinase C regulation

Protein kinase C (PKC) is a family of serine/threonine protein kinases that plays a central role in transducing extracellular signals into a variety of intracellular responses ranging from cell proliferation to apoptosis. Nine PKC genes have been identified in the human genome, which encode 10 proteins. Each member of this protein kinase family displays distinct biochemical characteristics and is

Test of three different audio-haptic navigation tools

The present paper presents a continuation of the work on navigational tools studied in two pilot tests [1], [2]. To further test the tools most popular in these pilot tests, as well as investigate possible influences on the spatial perception by different

Eye Tapping: How to Beat Out an Accurate Rhythm using Eye Movements

Abstract in UndeterminedThe aim of this study was to investigate how well subjects beat out a rhythm using eye movements and to establish the most accurate method of doing this. Eighteen subjects participated in an experiment were five different methods were evaluated and a fixation based method was found to be the most accurate. All subjects were able to synchronize their eye movements with a giv

Customer Service process IT-enabled support Fit or misfit? -A real world case

This paper is a description of a real world case which focuses on a method to define the major gaps between functional requirements and existing support in a traditional ERP system. To identify and define the major gaps the method is using short interviews, existing documentation and graphic process diagrams. The report covers the process Customer Contact – Order Acknowledgement for a global chemi

Direct writing with an MeV proton beam: Development and Applications

This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. This allows the fabrication of thre

Ca-Pd/Pt-Ge Compounds on the Zintl Border

Zintl compounds form a category in intermetallic chemistry somewhere between metallic and ionic compounds. Classical Zintl compounds form between electropositive and electronegative elements, such as the alkaline earth metals and the p-block elements, i.e. elements with a relatively large electronegativity difference. The concept is based on the idea of a complete charge transfer from the electro
