In Escherichia coli the codons CGG, AGG, UGG or GGG (NGG codons) but not GGN or GNG (where N is non-G) are associated with low expression of a reporter gene, if located at positions +2 to +5. Induction of a lacZ reporter gene with any one of the NGG codons at position +2 to +5 does not influence growth of a normal strain, but growth of a strain with a defective peptidyl-tRNA hydrolase (Pth) enzyme

Spatially coupled turbo-like codes (SC-TCs) have been shown to have excellent decoding thresholds due to the threshold saturation effect. Furthermore, even for moderate block lengths, the simulation results demonstrate a very good bit error rate performance in the waterfall region. In this paper, we discuss the effect of spatial coupling on the performance of TCs in the finite block-length regime.

A new Key Environmental Performance Indicators (KEPIs) approach has been developed considering the perspective of a designer who may like to improve the environmental performance of the products but has limited resources and understanding of complex environmental issues. This approach empowers the designer with indicators like the area of PWB, the amount of precious metals etc which account for th

Perceptual consumer requirements are often disregarded in the product development process. The consequence of this is that products may become more attractive to the design practitioners than to the target consumers. This paper describes the development of a new internet based tool, VIPET (Visual Internet Product Emotion Tool), that can be used for global evaluation of visual product qualities by

One of the latest additions in defining the test process is the upcoming ISO/IEC 29119 standard, which aims to define a universally applicable generic test process model. However, currently the standard does not offer any support for the adoption process of the model. In this paper, we present our framework, which aims to combine a maturity level-based approach with the standard process. Our objec

Many fire protection engineers working in the operative part of the rescue service feel that they do not have enough training for their role as Tactical leader and as On scene commander. There is a need for a tool for competence development and competence assurance. This report provides the results of a master’s thesis, with the aim to develop a prototype of such a tool. The tool is limited to the

There is a need to identify factors that affect the result of empirical studies in software engineering research. It is still the case that seemingly identical replications of controlled experiments result in different conclusions due to the fact that all factors describing the experiment context are not clearly defined and hence controlled. In this article, a scheme for describing the participant

We use simulations to investigate the effect of sampling frequency on common dependent variables in eye-tracking. We identify two large groups of measures that behave differently, but consistently. The effect of sampling frequency on these two groups of measures are explored and simulations are performed to estimate how much data are required to overcome the uncertainty of a limited sampling frequ

The process of selecting the right set of requirements for a product release is highly dependent on how well we succeed in prioritising the requirements candidates. There are different techniques available for requirements prioritisation, some more elaborate than others. In order to compare different techniques, a controlled experiment was conducted with the objective of understanding differences

As the focus of Augmented Reality (AR) shifts from consumer entertainment to industry appliances, there is a big need for exploratory studies to figure out what role they will play in the years to come. This thesis aims to investigate how AR could be used to enhance the selling, planning and installation of a security system. A prototype was developed to demonstrate some of the potential benefit

In order for manufacturing companies to remain competitive while also offering a high degree of customization for the customers, flexible robots that can be rapidly reprogrammed to new tasks need to be applied in the factories. In this paper we propose a method for the intuitive programming of an industrial mobile robot by combining robot skills, a graphical user interface and human gesture recogn

The Toulmin model is reminiscent of the classical argument structure called theepicheireme. Upon closer inspection they turn out to be fundamentally different.For the contemporary argumentation analyst or rhetorical critic, both structures are burdened with drawbacks. The Toulmin model suffers from unclarity regarding definitions of its elements and the epicheireme from divergent traditions in cla
