Recommendation domains for pond aquaculture
This publication introduces the methods and results of a research project that has developed a set of decision-support tools to identify places and sets of conditions for which a particular target aquaculture technology is considered feasible and therefore good to promote. The tools also identify the nature of constraints to aquaculture development and thereby shed light on appropriate interventions to realize the potential of the target areas. The project results will be useful for policy planners and decision makers in national, regional and local governments and development funding agencies, aquaculture extension workers in regional and local governments, and researchers in aquaculture systems and rural livelihoods.

DevOps in Practice -- A preliminary Analysis of two Multinational Companies
DevOps is a cultural movement that aims the collaboration of all the
stakeholders involved in the development, deployment and operation of soft-ware
to deliver a quality product or service in the shortest possible time. DevOps
is relatively recent, and companies have developed their DevOps prac-tices
largely from scratch. Our research aims to conduct an analysis on practic-ing
DevOps in +20 software-intensive companies to provide patterns of DevOps
practices and identify their benefits and barriers. This paper presents the
preliminary analysis of an exploratory case study based on the interviews to
relevant stakeholders of two (multinational) companies. The results show the
benefits (software delivery performance) and barriers that these companies are
dealing with, as well as DevOps team topology they approached during their
DevOps transformation. This study aims to help practitioners and researchers to
better understand DevOps transformations and the contexts where the practices
worked. This, hopefully, will contribute to strengthening the evidence
regarding DevOps and supporting practitioners in making better informed
decisions about the return of investment when adopting DevOps.Comment: 8 pages, 1 figure, 2 tables, conferenc
PerfVis: Pervasive Visualization in Immersive AugmentedReality for Performance Awareness
Developers are usually unaware of the impact of code changes to the
performance of software systems. Although developers can analyze the
performance of a system by executing, for instance, a performance test to
compare the performance of two consecutive versions of the system, changing
from a programming task to a testing task would disrupt the development flow.
In this paper, we propose the use of a city visualization that dynamically
provides developers with a pervasive view of the continuous performance of a
system. We use an immersive augmented reality device (Microsoft HoloLens) to
display our visualization and extend the integrated development environment on
a computer screen to use the physical space. We report on technical details of
the design and implementation of our visualization tool, and discuss early
feedback that we collected of its usability. Our investigation explores a new
visual metaphor to support the exploration and analysis of possibly very large
and multidimensional performance data. Our initial result indicates that the
city metaphor can be adequate to analyze dynamic performance data on a large
and non-trivial software system.Comment: ICPE'19 vision, 4 pages, 2 figure, conferenc
Software Measurement Activities in Small and Medium Enterprises: an Empirical Assessment
An empirical study for evaluating the proper implementation of measurement/metric programs in software companies in one area of Turkey is presented. The research questions are discussed and validated with the help of senior software
managers (more than 15 years’ experience) and then used for interviewing a variety of medium and small scale software companies in Ankara. Observations show that there is a
common reluctance/lack of interest in utilizing measurements/metrics despite the fact that they are well known in the industry. A side product of this research is that internationally recognized standards such as ISO and CMMI are pursued if they are a part of project/job
requirements; without these requirements, introducing those standards to the companies remains as a long-term target to increase quality
Design of the obstacle detection system with the SONAR MK3 on Guanay II AUV
Autonomous underwater vehicles (AUV)
perform inspection missions and intervention in known
and unknown environments, where it is necessary to
ensure their safety. The AUV must have the ability to
detect and avoid obstacles in the path of navigation.
This article, an obstacle detection system for
experimental Guanay II AUV is proposed, using a
mechanical scanning SONAR Tritech Micron MK3.
Since Guanay II operates autonomously, we have
designed software that allows adjustment and control
of the parameters of SONAR, and the acquisition and
processing of the signals obtained. Experimental tests
at sea have allowed to verify the correct operation of
software designed, as well as, experimental tests in a
controlled environment have allowed to determine the
optimal values of the basic parameters of SONAR.Postprint (published version
High-Performance Cloud Computing: A View of Scientific Applications
Scientific computing often requires the availability of a massive number of
computers for performing large scale experiments. Traditionally, these needs
have been addressed by using high-performance computing solutions and installed
facilities such as clusters and super computers, which are difficult to setup,
maintain, and operate. Cloud computing provides scientists with a completely
new model of utilizing the computing infrastructure. Compute resources, storage
resources, as well as applications, can be dynamically provisioned (and
integrated within the existing infrastructure) on a pay per use basis. These
resources can be released when they are no more needed. Such services are often
offered within the context of a Service Level Agreement (SLA), which ensure the
desired Quality of Service (QoS). Aneka, an enterprise Cloud computing
solution, harnesses the power of compute resources by relying on private and
public Clouds and delivers to users the desired QoS. Its flexible and service
based infrastructure supports multiple programming paradigms that make Aneka
address a variety of different scenarios: from finance applications to
computational science. As examples of scientific computing in the Cloud, we
present a preliminary case study on using Aneka for the classification of gene
expression data and the execution of fMRI brain imaging workflow.Comment: 13 pages, 9 figures, conference pape
