Domain‐specific neural networks improve automated bird sound recognition already with small amount of local data

2022

1. An automatic bird sound recognition system is a useful tool for collecting data of different bird species for ecological analysis. Together with autonomous recording units (ARUs), such a system provides a possibility to collect bird observations on a scale that no human observer could ever match. During the last decades, progress has been made in the field of automatic bird sound recognition, but recognizing bird species from untargeted soundscape recordings remains a challenge. 2. In this article, we demonstrate the workflow for building a global identification model and adjusting it to perform well on the data of autonomous recorders from a specific region. We show how data augmentatio…

Offsetting harmful ecological impacts by restoring conservation areas

2019

Ihmistoiminnasta aiheutuvat ekologisesti haitalliset vaikutukset voidaan kompensoida tuottamalla luonnon kannalta hyötyjä, esimerkiksi ennallistamalla elinympäristöjä tai perustamalla uusia luonnonsuojelualueita. Elinympäristön ennallistaminen mahdollistaa elinympäristön palautumisen kohti luonnontilaa. Tämän tutkimuksen tarkoituksena oli selvittää, voitaisiinko jo aiemmin suojelluilla alueilla tehtävällä ennallistamisella saavuttaa ekologisessa kompensaatiossa tarvittava luontohyöty. Voi ehkä vaikuttaa siltä, että tällä tavoin tuotetut hyödyt eivät ole luonnon kannalta lisäisiä, koska toimenpiteet kohdistuvat alueisiin, jotka ovat jo suojeltu. Suomessa on kuitenkin tällä hetkellä monia suo…

Topological ranks reveal functional knowledge encoded in biological networks: a comparative analysis

2022

Abstract Motivation Biological networks topology yields important insights into biological function, occurrence of diseases and drug design. In the last few years, different types of topological measures have been introduced and applied to infer the biological relevance of network components/interactions, according to their position within the network structure. Although comparisons of such measures have been previously proposed, to what extent the topology per se may lead to the extraction of novel biological knowledge has never been critically examined nor formalized in the literature. Results We present a comparative analysis of nine outstanding topological measures, based on compact vie…

Export Barrier Perceptions in Tanzania: The Influence of Social Networks

2012

In this article, the author empirically examines export barriers Tanzanian firms encounter in attempting to initiate and/or expand export activities and the strategies they use for overcoming these barriers. Based on a social network perspective, the research hypothesizes that firms exploiting diverse networks should normally encounter fewer export barriers. Using a survey dataset collected from 122 manufacturing firms, the findings support the notion that networking reduces export barriers. More specifically, exploiting a large number of strong ties relative to weak ties, and a large number of institutional ties relative to business ties, can substantially enhance firms’ capabilities of ov…

Psychobiosocial Experiences in Sport : Development and Initial Validation of a Semantic Differential Scale

2021

Abstract Objectives To develop and validate the Psychobiosocial Experience Semantic Differential scale in sport (PESD-Sport), a new measure to assess discrete emotions and performance-related experiences in sport as conceptualized within the individual zones of optimal functioning (IZOF; Hanin, 2000, 2007, 2010) framework. Method In Study 1, we developed a preliminary 53-item version of the scale using a semantic differential format in the construction of the items pertaining to 12 psychobiosocial modalities. We chose this format to attain a clear representation of psychobiosocial states between opposites along perceived performance functionality (i.e., functional, dysfunctional). The preli…

Los poetas ciegos y la ceguera en la poesía árabe: algunos casos destacados

2013

This paper deals with the verses of some relevant and famous blind Arab classical poets that talked about their blindness like the cases of al-A‛¿à, Ba¿¿ār ibn Burd and Abū-l-ɈAlā¿ al-Ma‛arrī among others. The study shows how each one of them faced his disability and the influence that their blindness had on their poetic production. This paper contains also the translation from the Arabic and tha analysis of the verses inspired by blindness to some seeing poets of Granada and the moderm Arabic poetry. El artículo se ocupa de los versos de algunos poetas árabes ciegos que se han hecho famosos en la literatura árabe clásica y que nos hablan de la ceguera como es el caso de al-A‛ à, Ba ār ibn …

An Energy Blockchain, a Use Case on Tendermint

2018

The recent advances in distributed energy systems require new models for exchanging energy among prosumers in microgrids. The blockchain technology promises to solve the digital issues related to distributed systems without a trusted authority and to allow quick and secure energy transactions, which are verified and cryptographically protected. Transactions are approved and subsequently recorded on all the machines participating in the blockchain. This work demonstrates how users, which are nodes of the energy and digital networks, exchange energy supported by a customized blockchain based on Tendermint. We focus on the procedures for generating blocks and defining data structures for stori…

An Efficient and Privacy-Preserving Blockchain-Based Authentication Scheme for Low Earth Orbit Satellite Assisted Internet of Things

2022

Recently, integrating satellite networks (e.g. Low-earth-orbit satellite constellation) into the Internet of Things (IoT) ecosystem has emerged as a potential paradigm to provide more reliable, ubiquitous and seamless network services. The LEO satellite networks serves as a key enabler to transform the connectivity across industries and geographical border. Despite the convenience brought from the LEO satellite networks, it arises security concerns, in which the essential one is to secure the communication between the IoT devices and the LEO satellite network. However, some challenges inheriting from the LEO satellite networks need to be considered : 1) the dynamic topology; 2) the resource…

2014

There has been a shifting change that has been in process over the years. From a hospital oriented based care offer in psyciatric health care, to a more desentralised direction where the care is oritented through community-based service. The idea is that everyone is to receive individual and costumised help in the community where they live. One wishes that every being gets the help they need in the community so that they can have the opportunity to be integrated and live as a part of the community. The number of bedposts in psychiatric hospitals has decreased over the years, and the community-based services has increased the offer. At the same time it has been noticed that some people are r…
