Linguistic reflection allows a running program to generate new program fragments and to integrate these into its own execution. The advantages of the technique include attaining high levels of genericity and accommodating system evolution. Here its use to provide generic programs in Java is compared for a particular example, natural join, against alternative implementation approaches.

In this paper, we propose a quantitative scenario-based method for dealing with the quality attributes for future software systems before any architecture implementation effort is actually done. The exploration of the possible design variants for a future system is done using so-called user scenarios. The method supports the software architects in developing future systems that meet their speci...

The mosaicing technique has been employed in more and more application fields, from entertainment to scientific ones. In the latter case, often the final evaluation is still left to human beings, that assess visually the quality of the mosaic. Many times, a lack of objective measurements in microscopic mosaicing may prevent the mosaic from being used as a starting image for further analysis. In...

Protection in experimental rabbit syphilis has been previously assessed by lesion development following intradermal challenge with Treponema pallidum. We have recently reported that passive immunization using monoclonal antibody M131 conveys partial protection as evidenced by significant lesion delays following intradermal challenge. To determine whether such delays in time to lesion appearance...

Indices of diffusion anisotropy calculated from diffusion coefficients acquired in two or three perpendicular directions are rotationally variant. In living monkey brain, these indices severely underestimate the degree of diffusion anisotropy. New indices calculated from the entire diffusion tensor are rotationally invariant (RI). They show that anisotropy is highly variable in different white ...

The occurrence of foodborne disease remains a widespread problem in both the developing and the developed world. A systematic and quantitative evaluation of food safety is important to control the risk of foodborne diseases. World-wide, many initiatives are being taken to develop quantitative risk analysis. However, the quantitative evaluation of food safety in all its aspects is very complex, ...

Predictive biomarkers are among the most direct steps towards converting precision medicine into a clinical reality. By their very definition they are fundamentally different from prognostic or diagnostic biomarkers—instead of helping identify individuals who will develop the disease, they focus on differentiating between those who will and will not " benefit " from treatment. Given this differ...

One day, you will discover a new adventure and knowledge by spending more money. But when? Do you think that you need to obtain those all requirements when having much money? Why don't you try to get something simple at first? That's something that will lead you to know more about the world, adventure, some places, history, entertainment, and more? It is your own time to continue reading habit....

This paper shows how to carry out a quantitative risk assessment, describing how each step in the process is carried out. We use the grade management system at the University of Bergen as a case study, evaluating the risk of wrong grades ending up in the university grade database.
