On the Presence of Green and Sustainable Software Engineering in Higher Education Curricula
Nowadays, software is pervasive in our everyday lives. Its sustainability and
environmental impact have become major factors to be considered in the
development of software systems. Millennials-the newer generation of university
students-are particularly keen to learn about and contribute to a more
sustainable and green society. The need for training on green and sustainable
topics in software engineering has been reflected in a number of recent
studies. The goal of this paper is to get a first understanding of what is the
current state of teaching sustainability in the software engineering community,
what are the motivations behind the current state of teaching, and what can be
done to improve it. To this end, we report the findings from a targeted survey
of 33 academics on the presence of green and sustainable software engineering
in higher education. The major findings from the collected data suggest that
sustainability is under-represented in the curricula, while the current focus
of teaching is on energy efficiency delivered through a fact-based approach.
The reasons vary from lack of awareness, teaching material and suitable
technologies, to the high effort required to teach sustainability. Finally, we
provide recommendations for educators willing to teach sustainability in
software engineering that can help to suit millennial students needs.Comment: The paper will be presented at the 1st International Workshop on
Software Engineering Curricula for Millennials (SECM2017
The Unfulfilled Potential of Data-Driven Decision Making in Agile Software Development
With the general trend towards data-driven decision making (DDDM),
organizations are looking for ways to use DDDM to improve their decisions.
However, few studies have looked into the practitioners view of DDDM, in
particular for agile organizations. In this paper we investigated the
experiences of using DDDM, and how data can improve decision making. An emailed
questionnaire was sent out to 124 industry practitioners in agile software
developing companies, of which 84 answered. The results show that few
practitioners indicated a widespread use of DDDM in their current decision
making practices. The practitioners were more positive to its future use for
higher-level and more general decision making, fairly positive to its use for
requirements elicitation and prioritization decisions, while being less
positive to its future use at the team level. The practitioners do see a lot of
potential for DDDM in an agile context; however, currently unfulfilled
Machine Learning in Wireless Sensor Networks: Algorithms, Strategies, and Applications
Wireless sensor networks monitor dynamic environments that change rapidly
over time. This dynamic behavior is either caused by external factors or
initiated by the system designers themselves. To adapt to such conditions,
sensor networks often adopt machine learning techniques to eliminate the need
for unnecessary redesign. Machine learning also inspires many practical
solutions that maximize resource utilization and prolong the lifespan of the
network. In this paper, we present an extensive literature review over the
period 2002-2013 of machine learning methods that were used to address common
issues in wireless sensor networks (WSNs). The advantages and disadvantages of
each proposed algorithm are evaluated against the corresponding problem. We
also provide a comparative guide to aid WSN designers in developing suitable
machine learning solutions for their specific application challenges.Comment: Accepted for publication in IEEE Communications Surveys and Tutorial
