ROS/Gazebo Based Simulation of Co-operative UAVs

2019

UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…

Effects of a ludic-motor program on motor development and early literacy skills in preschool children

2017

There is insufficient evidence in the literature about many correlations between motor and cognitive skills in 3-5 year old children [1]. The aim of this study was to explore the relationship between the development of the gross motor skills and the prerequisites of reading/writing following a ludic-motor program (LMP) in pre-school children. This study has involved 189 children (age: 4.62 ± 0.97 years; height: 107.83 ± 7.82 cm, body weight: 19.84 ± 4.95 kg) attending 8 kindergartens in Palermo. The children were randomly divided in a control group (C, n= 29), a 1-intervention group (I-1, n= 120) and a 2-intervention group (I-2, n= 40). I-1 and I-2 respectively performed 4 and 10 hours/week…

Cytoskeleton and Consciousness: An Evolutionary Based Review

2015

The fields of quantum biology and physics are now starting to unite to solve the mysteries associated with the field of evolutionary biology. One such question is the origination and propagation of consciousness which has always been ambiguous and in order to understand this concept, many theories have been proposed by several philosophers and scientists. This review paper agrees with the idea, that evolution is not a random process but hypothesizes, that its succession was managed by the expanding level of consciousness due to cell division and cell differentiation. Several theories propose that the cytoskeleton and its proteins are promoters for consciousness in the brain, which propagate…

Do Grading Gray Stimuli Help to Encode Letter Position?

2021

Numerous experiments in the past decades recurrently showed that a transposed-letter pseudoword (e.g., JUGDE) is much more wordlike than a replacement-letter control (e.g., JUPTE). Critically, there is an ongoing debate as to whether this effect arises at a perceptual level (e.g., perceptual uncertainty at assigning letter position of an array of visual objects) or at an abstract language-specific level (e.g., via a level of “open bigrams” between the letter and word levels). Here, we designed an experiment to test the limits of perceptual accounts of letter position coding. The stimuli in a lexical decision task were presented either with a homogeneous letter intensity or with a graded gra…

TREC: A tool kit for programming cognitive experiments in Applesoft BASIC

Gödel and the Blind Watchmaker

2015

While accepting that contingency is key to biological evolution, we wonder how much need there is for it. It is extremely difficult to talk about trends in evolution, but the fact remains that they are found here and there when evolutionary experiments are repeated. But we should ask, for example, whether there is an unavoidable tendency of life towards progressive complexity . This chapter deals with certain theoretical considerations from Logic and Computing on the conditions necessary to formulate a predictive evolutionary theory .

Learning processes in user training

2010

While the maturing research literature on training has generated increasingly sophisticated and more comprehensive theoretical models, the actual process through which users learn to use a system remains a relatively neglected area. The extant literature that has paid attention to processes have conceptualized these as structures and examined them through variance studies. In this paper, we address this knowledge gap by advancing hermeneutics as a lens to depict the process through which users come to learn about the system. We explain the hermeneutic process, situate it in a training context and illustrate our conceptualization by interpreting a specific training program at a large organiz…

La identidad de la diversidad funcional en la comunicación mediada por la tecnología

2017

El objeto de estudio de la investigación que a continuación se presenta gravita sobre el cambio ontológico que impone la tecnología en el ser humano. En concreto, el desarrollo de tecnologías de ayuda aplicadas a Sistemas Alternativos de Comunicación representa un interesante ejemplo de cómo dichos soportes actúan en la base de las interacciones sociales, la comunicación y, cómo esta mediación modifica la propia autoimagen e imagen social de la persona que la emplea. El presente estudio se centra en las personas con parálisis cerebral o enfermedad degenerativa neuronal y en la transformación identitaria que padecen al poderse comunicar con soportes autónomos de alta tecnología. La hipótesis…

Human motor system

2020

Abstract This chapter deals with the general issues of motor control and coordination rather than with neurophysiological mechanisms that form the basis for natural, coordinated movements. It is useful that, before we consider the basics of motor behaviours and disorders, we introduce a general theoretical framework adequate to consider issues of control and coordination in biological systems. However, it is impossible to separate issues of control from issues of coordination during natural human movements. Hence, this chapter will also deal with coordination, exploring how individual effectors (such as muscles, joints and limbs) are made to act together in a task-specific way. Ultimately, …
