The user interface generation process is still a complex issue. The manual creation process is time consuming and complex because it requires the combination of the application developer work and the user interface designer work. Therefore, many approaches investigate the automatic user interface generation. However, currently such approaches are not able to take usability aspects into account, due to the lack of information for such a process. Thus, we propose a tool which intends to ease and enhance the automatic user interface generation process for services by introducing service annotations that are attached to services and provide additional information for the process of automatic user interface generation.

This paper presents differential evolution with self-adaptation and local search for constrained multiobjective optimization algorithm (DECMOSA-SQP), which uses the self-adaptation mechanism from DEMOwSA algorithm presented at CEC 2007 and a SQP local search. The constrained handling mechanism is also incorporated in the new algorithm. Assessment of the algorithm using CEC 2009 special session and competition on constrained multiobjective optimization test functions is presented. The functions are composed of unconstrained and constrained problems. Their results are assessed using the IGD metric. Based on this metric, algorithm strengths and weaknesses are discussed.

The classical Hilbert transform on the real line is a valuable tool in signal processing. It constitutes the analytic signal which allows the determination of the instantaneous phase and amplitude of a one dimensional signal. For signals in in the Euclidean plane its analogue is the monogenic signal based on the Riesz transform, a generalization of the Hilbert transform to the plane. In addition to the instantaneous phase and amplitude, the orientation of intrinsically one dimensional structures in the plane can be determined. Various disciplines like geosciences, omnidirectional vision or astrophysics have to deal with signals arising on the two‐sphere. A Hilbert transform on the two‐sphere is well known from Clifford analysis. Yet it lacks a suitable interpretation from a signal processing viewpoint, especially in the frequency domain. In this paper we derive a series expansion of the Hilbert transform on the two‐sphere in terms of spherical harmonics. It provides an intuitive interpretation and turns out to be a gradient‐like operator acting only on the angular parts of the signal. This leads to intensity and rotation invariant signal analysis techniques on the two‐sphere in analogue to the Euclidean plane.

We will present a fundamental solution of the constructive interference‐problem of waves in two dimensions (also known as fringe patterns). Such problems are known from quantum physics and optics. In case of two one‐dimensional waves with same frequency but different phases and different amplitudes, the solution of their resulting superposition or interference is well known. We will generalize this solution to two dimensions. In case of two dimensions the waves can not only be described by their phases, amplitudes and frequencies, also geometric properties pop up since in two dimensions an infinite number of additional degrees of freedom exists. The wave equations will be given in a traditional Clifford‐valued tensor form. We will solve this problem in a hybrid matrix geometric algebra setting by mapping the traditional tensor expressions to Clifford numbers in conformal space. This Clifford number representation of two‐dimensional waves can be used to solve the interference‐problem linearly. Future work will consist of the generalization from 2D to multi‐dimensional waves.
