UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey
2021
Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…
Estimating regional differences in returns to education when schooling and location are determined endogenously
2010
While the growing supply of university skills is known to have agglomerated towards the large centers in Finland, there is no research knowledge available on the development of regional demands. This paper attempts to fill this gap by analyzing regional variation in the private-sector return to university education in Finland for the period 1970 - 2004. In the analysis, we focus on studying 1) whether there are differences in the return to university between different region types, and 2) to what extent can these differences - if they exist - be explained by differences in regional skill supply and unemployment. For the econometric analysis, we use a large register-based dataset constructed…
Postoperative Sagittal Balance Has Only a Limited Role in the Development of Adjacent Segment Disease After Lumbar Spine Fusion for Degenerative Lumb…
2022
Study Design. Retrospective additional analysis of a prospective follow-up study. Objectives. We aimed to find out whether poor postoperative sagittal alignment increases revisions for adjacent segment disease (ASD) after lumbar spine fusion (LSF) performed for degenerative lumbar spine disease. Summary of Background Data. Revisions for ASD accumulate over time after LSF for degenerative lumbar spine disease. The etiology of ASD is considered multifactorial. Yet, the role of postoperative sagittal balance in this process remains controversial. Materials and Methods. A total of 215 consecutive patients who had undergone an elective LSF surgery for spinal stenosis with (80%) or without (20%) …
Dialogicality in teaching process drama : three narratives, three frameworks
2018
This case study explores dialogicality in teaching process drama through the narratives and practices of three experienced drama teachers of the Open University. Dialogue is understood here in the context of ‘I-Thou’ attitude and as the phenomenon of heteroglossia. The analyses of the videotaped reflective interviews with the teachers and process dramas revealed a polyphonic picture of dialogicality in the teaching process, in which juxtapositions of communion and alterity are favoured. These findings may help drama teachers to become more conscious about the challenges and possibilities of generating a fluid and energised dialogicality in process drama. peerReviewed

Las estrategias del comercio especializado
2006
Este trabajo presenta una revisión y actualización de las estrategias empleadas por los minoristas especializados en su lucha competitiva con los minoristas generalistas. En un primer apartado se delimita el concepto de especialista, según la literatura académica, para pasar después a cuantificar su situación en España, en Europa y en Estados Unidos. A continuación se analiza la posición de los especialistas en los diferentes subsectores de actividad, para finalizar con una propuesta de las estrategias llevadas a cabo por los especialistas en España. This paper contains a review and update of the strategies used by specialized retailers to compete with their general counterparts. After defi…
Dog behaviour classification with movement sensors placed on the harness and the collar
2021
Dog owners’ understanding of the daily behaviour of their dogs may be enhanced by movement measurements that can detect repeatable dog behaviour, such as levels of daily activity and rest as well as their changes. The aim of this study was to evaluate the performance of supervised machine learning methods utilising accelerometer and gyroscope data provided by wearable movement sensors in classification of seven typical dog activities in a semi-controlled test situation. Forty-five middle to large sized dogs participated in the study. Two sensor devices were attached to each dog, one on the back of the dog in a harness and one on the neck collar. Altogether 54 features were extracted from th…

Emprendedor cooperativo de trabajo asociado y teorías de emprendimiento. Análisis en las cooperativas creadas en la Comunidad Valenciana en el period…
2015
Los objetivos de esta tesis doctoral son, por un lado, analizar los factores determinantes del proceso de emprendimiento de las cooperativas de trabajo asociado, y por otro configurar un modelo de emprendedor cooperativo, partiendo de dos supuestos o proposiciones de investigación: 1. La forma organizativa cooperativa de trabajo asociado plantea un contexto organizativo particular que difiere del contexto de las empresas capitalistas tradicionales y que influye en los procesos de dirección de la cooperativa, y que 2. Para quienes optan finalmente por la cooperativa de trabajo como forma organizativa para el desarrollo de un proyecto empresarial, los incentivos tienen un importante component…
