Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…
Towards multi-concern software development with Everything-as-Code
2022
As software is becoming a central element in our lives, more and more stakeholders have concerns. Unlike today, when developers stop their coding activities to satisfy these stakeholder concerns, we propose dealing with them as part of the coding workflow, the central element of programmers’ daily duties. This can be achieved by extending the approach that we call Everything-as-Code (EaC) beyond software engineers and operators. peerReviewed
Data-Driven Evolutionary Optimization: An Overview and Case Studies
2019
Most evolutionary optimization algorithms assume that the evaluation of the objective and constraint functions is straightforward. In solving many real-world optimization problems, however, such objective functions may not exist, instead computationally expensive numerical simulations or costly physical experiments must be performed for fitness evaluations. In more extreme cases, only historical data are available for performing optimization and no new data can be generated during optimization. Solving evolutionary optimization problems driven by data collected in simulations, physical experiments, production processes, or daily life are termed data-driven evolutionary optimization. In this…
Startup Metrics That Tech Entrepreneurs Need to Know
2020
Metrics can be used by firms to make more objective decisions based on data. Software startups in particular are characterized by the uncertain or even chaotic nature of the contexts in which they operate. Using data in the form of metrics can help software startups to make the right decisions amid uncertainty and limited resources. However, whereas conventional business metrics and software metrics have been studied in the past, metrics in the specific context of software startups have not been studied. In this chapter, we present the results of a multivocal literature review to offer you 118 metrics practitioner experts think software startups should measure. These metrics can give you id…
The reliability of spanish and german electricity forward prices. Databases and price discovery process
2021
Given the existence of different databases from different sources that offer information on forward electricity prices, the need to compare them arises to guarantee that research results and trading decisions based on them are not sensitive to the database used. We worked with forward electricity prices traded over the counter, closest month to maturity, covering the period from 2010 to 2016 for the Spanish over the counter (OTC) market, and from 2008 to 2016 for the German OTC market. The goal of this paper was to test whether there were significant discrepancies between the price series provided by two of the main agencies of financial information (Thomson Reuters and Bloomberg), as well …
Datu izmaiņu pārlūkošanas moduļa izstrāde nekustamā īpašuma nodokļa administrēšanas sistēmai NINO
2018
Darbā aprakstīta izstrādes gaita nekustamā īpašuma nodokļa administrēšanas sistēmas NINO papildinājuma – datu izmaiņu pārlūkošanas moduļa - risinājumam. Tas paredzēts NINO lietotājiem ērtākai un savām vajadzībām pielāgojamai datu izmaiņu vēstures pārlūkošanai. Risinājums atvieglo gan Latvijas pašvaldību nodokļu inspektoru darbu, gan šo darbinieku kontroli ar datu izmaiņām saistītos jautājumos, kā arī samazina nepieciešamību griezties pēc palīdzības pie NINO klientu konsultantiem. Datu izmaiņu vēsturi iespējams attēlot uz ekrāna vai izklājlapu lietotnē Microsoft Excel, saņemot informāciju, kāds lietotājs, kad un kā izmainījis konkrēta NINO objekta datus. Programmprodukta izstrāde veikta, iev…
Datapackage for national high-resolution conservation prioritisation of boreal forests
2023
This data package concerns the following work: Ninni Mikkonen, Niko Leikola, Joona Lehtomäki, Panu Halme, Atte Moilanen, National high-resolution conservation prioritisation of boreal forests, Forest Ecology and Management, Volume 541, 2023, 121079 ISSN 0378-1127 https://doi.org/10.1016/j.foreco.2023.121079 The overall objective of the work was to develop spatial prioritizations that can assist the forest conservation programme METSO (The Finnish Government 2008; 2014) to make well-informed decisions about acquisition of forests for protection. The results are also aimed to be useful for other actors interested in forest conservation or biodiversity friendly forest management. We focused th…
Predicting the availability of users' devices in Decentralized Online Social Networks
2018
The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…
Data-driven Interactive Multiobjective Optimization : Challenges and a Generic Multi-agent Architecture
2020
In many decision making problems, a decision maker needs computer support in finding a good compromise between multiple conflicting objectives that need to be optimized simultaneously. Interactive multiobjective optimization methods have a lot of potential for solving such problems. However, the growth of complexity in problem formulations and the abundance of data bring new challenges to be addressed by decision makers and method developers. On the other hand, advances in the field of artificial intelligence provide opportunities in this respect. We identify challenges and propose directions of addressing them in interactive multiobjective optimization methods with the help of multiple int…
From Agile Software Development to Mercury Business
2014
The rapid downfall of the Nokia software ecosystem has radically altered the landscape of software industry in Finland in recent years. There has been a shift from largely corporate driven way of working, which is often dominant in large companies, to more agile practices, and in general software organizations are seeking new, leaner ways of composing, delivering, and using software also inside already established companies. To accelerate this transformation in large scale, a collaborative research program has been created, called Need for Speed (N4S). In this paper, we give an insight to the joint goals and concrete actions of the program and discuss the motivations of individual companies…
