Dynamic Office Environments Improve Brain Activity and Attentional Performance Mediated by Increased Motor Activity.
2018
Current research demonstrates beneficial effects of physical activity on brain functions and cognitive performance. To date, less is known on the effects of gross motor movements that do not fall into the category of sports-related aerobic or anaerobic exercise. In previous studies, we found beneficial effects of dynamic working environments, i.e., environments that encourage movements during cognitive task performance, on cognitive performance and corresponding brain activity. Aim of the present study was to examine the effects of working in a dynamic and a static office environment on attentional and vigilance performance, and on the corresponding electroencephalographic (EEG) brain oscil…
Movement Detection with Event-Based Cameras: Comparison with Frame-Based Cameras in Robot Object Tracking Using Powerlink Communication
2018
Event-based cameras are not common in industrial applications despite the fact that they can add multiple advantages for applications with moving objects. In comparison with frame-based cameras, the amount of generated data is very low while keeping the main information in the scene. For an industrial environment with interconnected systems, data reduction becomes very important to avoid network congestion and provide faster response time. However, the use of new sensors as event-based cameras is not common since they do not usually provide connectivity to industrial buses. This work develops a network node based on a Field Programmable Gate Array (FPGA), including data acquisition and trac…
Differential Effects of Interruptions and Distractions on Working Memory Processes in an ERP Study
2020
Interruptions (interfering stimuli to respond to) and distractions (interfering stimuli to be ignored) have been shown to negatively impact performance, particularly in tasks requiring working memory (WM). This study investigated how these two types of external interference affect task performance and attentional and WM processes as indexed by specific event-related potentials (ERPs) of the EEG. A Continuous Number Task (CNT) was applied, in which participants had to either decide whether the current number (condition without WM load) or the sum of the current and the preceding number (condition with WM load) was odd or even while responding to interlaced single letters (interruptions) or i…
Union representation and prevention of occupational risks during the crisis: impact and limits
2019
La investigación que presentamos estudia el impacto de la intervención sindical en materia de salud laboral, en lo que se refiere tanto a la gestión preventiva y creación de una cultura participativa como en los procesos de vigilancia y control de las condiciones de trabajo. A tal efecto, se han consultado las principales encuestas nacionales e internacionales sobre gestión de riesgos laborales en las empresas, analizando los datos más relevantes en base a modelos de regresión logística y lineal, lo que ha permitido constatar que la representación sindical de los trabajadores en la empresa (generalista y especializada) correlaciona positivamente con el desarrollo de las principales dimensio…
Masters of their own time? Working carers’s visions about combining retirement and caring
2011
How do working careers anticipate the timing of retirement and the weight of care commitments related to other activities when retired? This question is discussed by analysing the experiences of Finnish working careers. Most of the interviewees indicated that helping parent(s) would be part of their own retirement, but after leaving full-time work they would also like to devote time for their other personal interests, too. Working careers are willing to engage in caring when retired. However, they also have a desire to outline their caring tasks and manage their own time. nonPeerReviewed

A CUDA-based implementation of an improved SPH method on GPU
2021
We present a CUDA-based parallel implementation on GPU architecture of a modified version of the Smoothed Particle Hydrodynamics (SPH) method. This modified formulation exploits a strategy based on the Taylor series expansion, which simultaneously improves the approximation of a function and its derivatives with respect to the standard formulation. The improvement in accuracy comes at the cost of an additional computational effort. The computational demand becomes increasingly crucial as problem size increases but can be addressed by employing fast summations in a parallel computational scheme. The experimental analysis showed that our parallel implementation significantly reduces the runti…
Robust Selective Stereo SLAM without Loop Closure and Bundle Adjustment
2013
This paper presents a novel stereo SLAM framework, where a robust loop chain matching scheme for tracking keypoints is combined with an effective frame selection strategy. The proposed approach, referred to as selective SLAM (SSLAM), relies on the observation that the error in the pose estimation propagates from the uncertainty of the three-dimensional points. This is higher for distant points, corresponding to matches with low temporal flow disparity in the images. Comparative results based on the reference KITTI evaluation framework show that SSLAM is effective and can be implemented efficiently, as it does not require any loop closure or bundle adjustment.
Tyytyväisyys työaikapankkiin
2009
Tutkimuksessa tarkasteltiin työaikapankkiin tyytyväisyyttä ennustavia tekijöitä. Tutkimus perustuu yhdeksässä työorganisaatiossa tehdyn kyselyn aineistoon (N = 268). Analyysit suoritettiin polkuanalyysina, jolloin selittäjien kausaalinen järjestys ja keskinäinen riippuvuus pystyttiin ottamaan huomioon. Selvä enemmistö vastaajista oli tyytyväisiä työaikapankkiin. Tyytyväisyyttä lisäsivät mahdollisuus kokonaisen vapaa-päivän viettämiseen säästetyistä tunneista, korkea asema organisaatiossa sekä työntekijöiden organisaation johdolta saama tuki. Tyytyväisyyttä heikensivät ongelmat säästettyjen vapaiden käytössä sekä työaikatilin saldorajojen huono mitoitus suhteessa työtehtävien vaativuuteen. K…
NASH EVOLUTIONARY ALGORITHMS: TESTING PROBLEM SIZE IN RECONSTRUCTION PROBLEMS IN FRAME STRUCTURES
2016
The use of evolutionary algorithms has been enhanced in recent years for solving real engineering problems, where the requirements of intense computational calculations are needed, especially when computational engineering simulations are involved (use of finite element method, boundary element method, etc). The coupling of game-theory concepts in evolutionary algorithms has been a recent line of research which could enhance the efficiency of the optimum design procedure and the quality of the design solutions achieved. They have been applied in several fields of engineering and sciences, mainly, in aeronautical and structural engineering (e.g: in computational fluid dynamics and solid mech…
