Recoil Polarization for Delta Excitation in Pion Electroproduction

We measured angular distributions of recoil-polarization response functions for neutral pion electroproduction for W=1.23 GeV at Q2=1.0 (GeV/c)2, obtaining 14 separated response functions plus 2 Rosenbluth combinations; of these, 12 have been observed for the first time. Dynamical models do not describe quantities governed by imaginary parts of interference products well, indicating the need for a

Object-oriented modeling and simulation of power systems using Modelica

Traditionally the simulation of transient and voltage stability in power systems has been constrained to tools developed specifically for this purpose, e.g. Simpow, PSS/E, ETMSP and Eurostag. While being efficient and thereby able to simulate large systems, their component models are often encapsulated and difficult or impossible to examine and modify. Also, these simulators often require substant

Predictive text entry using syntax and semantics

Most cellular telephones use numeric keypads, where texting is supported by dictionaries and frequency models. Given a key sequence, the entry system recognizes the matching words and proposes a rank-ordered list of candidates. The ranking quality is instrumental to an effective entry. This paper describes a new method to enhance entry that combines syntax and language models. We first investigat

Self-Tuning Controllers Based on Pole-Zero Placement

The paper gives a review of pole-placement design for systems with known parameters, then focuses entirely on the servos. Adaptive pole-placement algorithms are discussed, leading to the formulation of explicit and implicit schemes, and simulation of the behaviour of the alorithms is given.

Integrating Packaging and Logistics in Industrial Development

Global Enterprises today are dependent on performance within complex networks. To become effective and efficient, it is more important than ever to organize operations in order to capitalize on resources and to integrate different activities. This means that the supply chain and logistics have become core activities in international enterprises. Transportation has also become an issue based on the

IC-Project and Verification Course: Teaching Top Down Analog/Mixed Signal Design

This paper describes a project course that focuses on the design of analog and mixed signal circuits through a systematic top down design flow. In the project, the student will be involved in the planning, modeling, circuit level design, physical level implementation and measurement verification of for example a successive approximation (SA) ADC or a class-D audio amplifier. Throughout the project

Exploiting the Common-Mode Signal in xDSL

Communication over the copper twisted-pair channel is performed by transmitting and receiving differential-mode (DM) signals. In this paper, we extend the conventional DM receive scheme by incorporating the common-mode (CM) signal, which can be extracted at the end of every wire pair. We assess the potential of this idea for digital subscriber line systems (xDSL) in terms of channel capacity using

Hydrophobic Interactions in Bioseparation - Applications of Modified Green Fluorescent Protein

This thesis describes interactions that are salt-promoted and mainly based on the hydrophobicity of proteins. A series of variants of the green fluorescent protein (GFP) was first constructed by site-directed mutagenesis. Several tags with various properties were then genetically fused to the N-terminus of GFP. The protein variants constructed had small characteristic differences in hydrophobicity
