STIS/CCD data were acquired in a time series mode on α Cen A & B to test limitations to ultra high Signal to Noise (S/N) capabilities. In order to reach a Poisson limited noise level of nearly 40,000 on α Cen A the data were acquired in a spectral mode to spread the image over a full row of pixels, and with an exposure time that led to strong over-saturation. Each 10s exposure resulted in detec...

This thesis attempts to study the technological progress of wireless technology and the wireless industry throughout history, using high-level, non-device specific performance metrics. Such metrics are developed by following the broad functional category approach. The analysis performed is both qualitative and quantitative. Firstly, the quantitative study provides a general perspective of how t...

One of the arguments for functional programming is better modular design. By analyzing publications advocating this approach, in particular through the example of a framework for financial contracts, we assess is strengths and weaknesses, and compare it with object-oriented design. The overall conclusion is that objectoriented design, especially in a modern form supporting high-level routine ob...

In this paper, a fuzzy multi-objective constrained optimization problem (FMCOP) is converted to a single-objective constrained optimization problem with equality and inequality constraints (SCOP) by using α−level set of the fuzzy vector and weighting approach. A trust-region algorithm for solving problem (SCOP) is introduced to obtain α−pareto optimal solutions of problem (FMCOP). An εα−stabili...

At its most fundamental, cognition as displayed by biological agents (such as humans) may be described as being the manipulation and utilisation of memory. A low-level approach to the associative sensory-motor development of cognition is then appropriate, rather than the more common higher-level functional approach. A novel theoretical framework – the memory-based cognitive framework (MBCF) – i...

This paper presents an extension of current Global Dynamic Window approaches to arbitrarily shaped holonomic and non-holonomic mobile robots. The algorithm proceeds in two stages. In order to account for an arbitrary robot cross section, the first stage takes the robot’s orientation explicitly into account by constructing a navigation function in the (x, y, θ) configuration space. In a second s...

Abnormal accumulation of filamentous α-synuclein (α-syn) in neurons, regarded as Lewy bodies (LBs), are a hallmark of Parkinson disease (PD). Although the exact mechanism(s) underlying LBs formation remains unknown, autophagy and ER stress response have emerged as two important pathways affecting α-syn aggregation. In present study we tested whether cells with the tetracycline-off inducible ove...
