Analysis and Performance Evaluation of the IEEE 802.16 ARQ Mechanism
2008
The IEEE 802.16 standard defines the ARQ mechanismas a part of the MAC layer. The functioning of the ARQmechanism depends on a number of parameters. The IEEE802.16 specification defines them but it does not provide concrete values and solutions. This paper studies the key features and parameters of the 802.16 ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, an algorithm to build block sequences, the ARQ feedback intensity, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and the ARQ block size. We ran simulation scenarios to study these parameters and how they impact the performance of application protoc…
Software Startups – A Research Agenda
2016
Software startup companies develop innovative, software-intensive products within limited timeframes and with few resources, searching for sustainable and scalable business models. Softwarestartups are quite distinct from traditional mature software companies, but also from micro-,small-, and medium-sized enterprises, introducing new challenges relevant for software engineeringresearch. This paper’s research agenda focuses on software engineering in startups, identifying,in particular, 70+ research questions in the areas of supporting startup engineering activities,startup evolution models and patterns, ecosystems and innovation hubs, human aspects in softwarestartups, applying startup conc…
Fuzzy Methods and Approximate Reasoning in Geographical Information Systems
2014
This issue has been dedicated to the usage of fuzzy logic in the context of Geographical Information Systems (GIS) and were receveid the following papers whose contents are described below: - in the paper of A. Hofmann, S. Hoskova-Mayerova, and V. Talhofer, the authors use a GIS tool which is useful to study the influence of geographic and climatic factors on the terrain passability of armed forces and the Integrated Rescue System. - In the first paper of S. Sessa and F. Di Martino, the authors propose the usage of the well known Extended Gustafson-Kessel clustering method, encapsulated in a GIS tool, for detecting hotspots in spatial analysis. The data consist of geo-referenced patterns co…
The Electronic Historical Latvian Dictionary Based on the Corpus of Early Written Latvian Texts
2016
The Electronic Historical Latvian Dictionary Based on the Corpus of Early Written Latvian Texts This article deals with the development of the Electronic Historical Latvian Dictionary (http://www.tezaurs.lv/lvvv) based on the Corpus of Early Written Latvian Texts (http://www.korpuss.lv/senie/). Some issues concerning the compilation and processing of the corpus data are discussed and the main sources added to the Corpus during the four-year project are described: the 16th c. Lord’s Prayers , 17th c. dictionaries, texts of oaths and laws, religious texts and so-called dedication poetry. The aim of the project is to compile a pilot electronic dictionary of 16th–17th century Latvian where all…
INTEGRATED SYSTEMS FOR PLANNING AND RESOURCES MANAGEMENT IN COMPANIES
2014
Information is one of the most valuable resources of a company, since with it and around it the whole set of business processes unfold within companies. Till using internet companies were eager to find information that was necessary for the functioning and development of the company; now things have changed radically: the information is abundant and is provided through all possible channels; today, in order to thrive you have to „choose" and to filter the information to remain competitive on the market you are active on. The performance of an enterprise is influenced by its ability to adapt itself to the environment, by the effectiveness of its actions in capitalizing opportunities, by its …
Verification of IRRILAB Software Application for the Hydraulic Design of a Micro-Irrigation System by Using IRRIPRO for an Apple Farm in Sicily
2021
In recent years, many studies have been performed to develop simple and accurate methods to design micro-irrigation systems. However, most of these studies are based on numerical solutions that require a high number of iterations and attempts, without ensuring to maximize water use efficiency and energy-saving. Recently, the IRRILAB software, which is based on an analytical approach to optimally design rectangular micro-irrigation units, has been developed, providing the solution corresponding to the maximum energy-saving condition, for any slope of the laterals and of the manifold. One IRRILAB limitation is that, according to its theoretical basis, the rectangular planform geometry and uni…
Web 2.0 under the light of free software
2009
The development of Web 2.0 has favoured a closer relation between Internet users and the different web applications that facilitate creating, sharing and structuring digital information in a horizontal and collaborative way through so-called social software. Social software includes tools that are familiar to us all, such as chats, forums, blogs, wikis, syndication standards (RSS type), social tagging, multimedia file sharing, social networking, etc. They are tools oriented to give the user a greater capacity of interaction, and a stronger control over the content and the format in which they can be presented.
El Discurso del profesorado de educación musical en la innovación educativa con tic: posicionamientos en la evaluación del software tactus.
2014
This paper presents teachers positioning analysis around the assessment of ad hoc software designed for learning musical rhythm called “Tactus”. The main objective is to study the teachers speeches and opinions in software assessment, which is built through the speeches analysis (n = 115) in 8 focus groups, with a descriptive model of 5 clusters. The study gives us a diverse, varied and a full picture in educational software evaluation trough teachers’ discourses analysis. En este estudio empírico analizamos los discursos y posicionamientos del profesorado en torno a la evaluación de un software diseñado ad hoc, para el aprendizaje del ritmo musical denominado Tactus. El objetivo de investi…
Softening of Silica Filled Styrene-Butadiene Rubber under Uniaxial Cyclic Loading
2016
Stress-strain behaviour of silica filled styrene-butadiene rubber showed strong hysteresis and cyclic softening, while these effects were almost negligible for the neat rubber. Significant Mullins effect occurs between the first and second loading cycles, whereupon samples reach their steady state after four repeated cycles. The degree of softening increases with volume content of silica characterizing the softening effect as a breakdown of the filler-formed microstructure defined by both, specific interactions in the filler associations and between the filler and rubber matrix. Contribution of different damage mechanisms to the total energy losses on different stages of extension was estim…
Leadership as an enabler of professional agency and creativity : case studies from the Finnish information technology sector
2018
This paper summarizes and elaborates the findings of a research project on leadership as an enabler of professional agency and creativity in information technology organizations. The synthesis in this paper is based on a summary of three primary studies. Each of the studies approached leadership, creativity and/or professional agency with a specific focus. Leaning on a mixed‐methods and ethnographic approach, including various empirical data collection and analytical tools, the project investigated the relationship between professional agency and creativity; issues that frame professional agency and creativity; and the meaning of leadership practices for the enhancement of agency and creati…
