The Perception of Technical Debt in the Embedded Systems Domain: An Industrial Case Study
- 2016

- Technical Debt Management (TDM) has drawn the attention of software industries during the last years, including embedded systems. However, we currently lack an overview of how practitioners from this application domain perceive technical debt. To this end, we conducted a multiple case study in the embedded systems industry, to investigate: (a) the expected lifetime of components that have TD, (b) the most frequently occurring types of TD in them, and (c) the significance of TD against run-time quality attributes. The case study was performed on seven embedded systems industries (telecommunications, printing, smart manufacturing, sensors, etc.) from five countries (Greece, Netherlands, Sweden, Austria, and Finland). The results of the case study suggest that: (a) maintainability is more seriously considered when the expected lifetime of components is larger than ten years; (b) the most frequent types of debt are test, architectural, and code debt; and (c) in embedded systems the run-time qualities are prioritized compared to design-time qualities that are usually associated with TD. The obtained results can be useful for both researchers and practitioners: the former can focus their research on the most industrially-relevant aspects of TD, whereas the latter can be informed about the most common types of TD and how to focus their TDM processes.

Secure migration of legacy applications to the web

Conference paper (peer-reviewed)abstract
- In software engineering, migration of an application is the process of moving the software from one execution platform to another. Nowadays, many desktop applications tend to migrate to the web or to the cloud. Desktop applications are not prepared to face the hostile environment of the web where applications frequently receive harmful data that attempt to exploit program vulnerabilities such as buffer overflows. We propose a migration process for desktop applications with a text-based user interface, which mitigates existing security concerns and enables the software to perform safely in the web without modifying its of the source code. Additionally, we describe an open source tool that facilitates our migration process.

Effects of increased wholegrain consumption on immune and inflammatory markers in healthy low habitual wholegrain consumers.
- 2016
-
In: European Journal of Nutrition. - : Springer Science and Business Media LLC. - 1436-6207 .- 1436-6215. ; 55:1, s. 183-195
-
Journal article (peer-reviewed)abstract
- Wholegrain (WG) consumption is associated with reduced risk of cardiovascular disease, but clinical data on inflammation and immune function is either conflicting or limited. The objective of this study was to assess the impact of increasing WG consumption to at least 80 g/day on markers of inflammation and glucose metabolism and on phenotypic and functional aspects of the immune system, in healthy, middle-aged adults with low habitual WG intake. Subjects consumed a diet high in WG (> 80 g/day) or low in WG (

Increased Whole Grain Consumption Does Not Affect Blood Biochemistry, Body Composition, or Gut Microbiology in Healthy, Low-Habitual Whole Grain Consumers
- 2015

Journal article (peer-reviewed)abstract
- Background: Whole-grain (WG) foods have been suggested to reduce the risk of cardiovascular disease, but studies are inconsistent and effects on cardiovascular risk markers are not clear. Objective: The objective of this study was to assess the impact of increasing WG consumption to at least 80 g/d on overall dietary intake, body composition, blood pressure (BP), blood lipids, blood glucose, gastrointestinal microbiology, and gastrointestinal symptoms in healthy, middle-aged adults with habitual WG intake 80 g/d) or low in WG[

Research state of the art on GoF design patterns: A mapping study
- 2013
-
In: Journal of Systems and Software. - : Elsevier BV. - 0164-1212. ; 86:7, s. 1945-1964
-
Journal article (peer-reviewed)abstract
- Design patterns are used in software development to provide reusable and documented solutions to common design problems. Although many studies have explored various aspects of design patterns, no research summarizing the state of research related to design patterns existed up to now. This paper presents the results of a mapping study of about 120 primary studies, to provide an overview of the research efforts on Gang of Four (GoF) design patterns. The research questions of this study deal with (a) if design pattern research can be further categorized in research subtopics, (b) which of the above subtopics are the most active ones and (c) what is the reported effect of GoF patterns on software quality attributes. The results suggest that design pattern research can be further categorized to research on GoF patterns formalization, detection and application and on the effect of GoF patterns on software quality attributes. Concerning the intensity of research activity of the abovementioned subtopics, research on pattern detection and on the effect of GoF patterns on software quality attributes appear to be the most active ones. Finally, the reported research to date on the effect of GoF patterns on software quality attributes are controversial; because some studies identify one pattern's effect as beneficial whereas others report the same pattern's effect as harmful.
