Autistisen lapsen toimintaan sitoutuminen sensorisen integraation terapiassa : havainnointimittarin muokkaus
2011
Tämän tutkimuksen tarkoituksena oli autistisen lapsen terapiatilanteen havainnointiin soveltuvan yhteistoimintaan sitoutumisen mittarin kehittäminen. Sitoutumisen mittari muokattiin Gallon, Tickle-Degnenin ja Costerin ”Challenge Management Rating Scale” (CMRS) – mittarista. Ensin sitoutumista tutkittiin teoreettisesti: minkälainen ilmiö sitoutuminen oikeastaan on ja mitä olennaisia tekijöitä siihen liittyy. Taustateorioina käytettiin toimintaterapian teoriaa, sensorisen integraation teoriaa, motivaatioteorioita ja teorioita varhaisesta vuorovaikutuksesta. Mittarin muokkaaminen perustui 1) tutkimuksessa koottuun teoriaan, 2) autismitutkimukseen 3) mittarin muokkaajien kliiniseen kokemukseen …
Data Mining for the Security of Cyber Physical Systems Using Deep-Learning Methods
2022
Cyber Physical Systems (CPSs) have become widely popular in recent years, and their applicability have been growing exponentially. A CPS is an advanced system that incorporates a computation unit along with a hardware unit, allowing for computing processes to interact with the physical world. However, this increased usage has also led to the security concerns in them, as they allow potential attack vendors to exploit the possibilities of committing misconduct for their own benefit. It is of paramount importance that these systems have comprehensive security mechanisms to mitigate these security threats. A typical attack vector for a CPS is malicious data supplied by compromised sensors that…
Quality, Reliability, Security and Robustness in Heterogeneous Systems
2020
This book constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Quality, Reliability, Security and Robustness in Heterogeneous Networks, QShine 2019, held in Shenzhen, China, in November 2019. The 16 revised full papers were carefully reviewed and selected from 55 submissions. The papers are organized thematically in tracks, starting with mobile systems, cloud resource management and scheduling, machine learning, telecommunication systems, and network management.
Understanding the Role of Sensorimotor Beta Oscillations
2021
Beta oscillations have been predominantly observed in sensorimotor cortices and basal\ud ganglia structures and they are thought to be involved in somatosensory processing\ud and motor control. Although beta activity is a distinct feature of healthy and pathological\ud sensorimotor processing, the role of this rhythm is still under debate. Here we review\ud recent findings about the role of beta oscillations during experimental manipulations (i.e.,\ud drugs and brain stimulation) and their alteration in aging and pathology. We show how\ud beta changes when learning new motor skills and its potential to integrate sensory input\ud with prior contextual knowledge. We conclude by discussing a n…
Big Data Applications for Disaster Management
2017
International audience; The term "disaster management" comprises both natural and man-made disasters. Highly pervaded with various types of sensors, our environment generates large amounts of data. Thus, big data applications in the field of disaster management should adopt a modular view, going from a component to nation scale. Current research trends mainly aim at integrating component, building, neighborhood and city levels, neglecting the region level for managing disasters. Current research on big data mainly address smart buildings and smart grids, notably in the following areas: energy waste management, prediction and planning of power generation needs (based on smart meter readings,…
Ultrasound accelerated esterification of bile acids
2004
In this study power ultrasound accelerated esterification reactions of some model substances and bile acids were done. In the model reactions the best result was 19-fold increase in the reaction rate when using ultrasound and the temperature was allowed to rise during the irradiation. In the case of bile acid methyl esters a clear increase in the reaction rates was also observed by ultrasonic irradiations.
Less Data Same Information for Event-Based Sensors: A Bioinspired Filtering and Data Reduction Algorithm
2018
Sensors provide data which need to be processed after acquisition to remove noise and extract relevant information. When the sensor is a network node and acquired data are to be transmitted to other nodes (e.g., through Ethernet), the amount of generated data from multiple nodes can overload the communication channel. The reduction of generated data implies the possibility of lower hardware requirements and less power consumption for the hardware devices. This work proposes a filtering algorithm (LDSI&mdash
Rapid learning of a spatial memory task in a lacertid lizard (Podarcis liolepis).
2018
Abstract Mammals and birds are capable of navigating to a goal using learned map-like representations of space (i.e. place learning), but research assessing this navigational strategy in reptiles has produced inconclusive results, in part due to the use of procedures that do not take account of the peculiarities of reptilian behavior and physiology. Here I present a procedure suitable for testing spatial cognition that exploits a naturally evolved, ethologically relevant ability common to many lizards (i.e. refuge seeking behavior). The procedure requires lizards to learn the location of an open refuge inside a rectangular arena containing artificial refuges in every corner, using distal ex…
Recent advances of electrochemical and optical biosensors for detection of C-reactive protein as a major inflammatory biomarker
2020
Abstract Early detection of inflammatory mediators including C-reactive protein (CRP) is of great diagnostic importance in many human diseases. CRP elevates very fast in conditions such as tissue injuries, infections, cancers, and renal and cardiovascular diseases. Conventional techniques for detecting CRP are based on antigen–antibody, agglutination, and precipitation reactions. Newer methods based on immunoturbidimetry and immunonephelometry are also time-consuming and relatively expensive. For solving these problems, highly efficient techniques based on CRP-biosensors have been introduced. Here, our aim was to summarize the features of recent biosensors for detection of CRP in biological…
Electrochemical biosensors for glucose based on metal nanoparticles
2013
Abstract Nanotechnology has affected almost all aspects of biomedicine. The integration of nanomaterials has contributed to the selectivity, the versatility, the stability and especially the sensitivity of bioelectronic devices, including biosensors. In this field, nanomaterials have been employed as enzyme immobilizers, enzyme stabilizers, surface modifiers or labeling factors or have provided individualized catalytic effects. Among other sensing platforms, glucose biosensors are of special clinical and industrial significance because of their role in monitoring blood-glucose levels in diabetes mellitus, one of the most prevalent metabolic disorders worldwide. Similar to other sensing plat…
