Surfactant Association: Recent Theoretical and Experimental Developments

1991

A theoretical model describing the association of ionic surfactants into rod-shaped micelles is combined with an approximate formula for the viscosity increase induced by rod-shaped aggregates. It is shown that most of the thermodynamic parameters of the association model can be obtained from viscosity measurements. The approach is applied to micellar solutions of hexadecylpyridinium salts. The pronounced effect of counter-ion concentration on the growth of rod-shaped micelles can be attributed to a slightly higher degree of counter-ion association in the cylindrical part than in the end portions. An attempt is made to explain the finding that the degree of counter-ion association is virtua…

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…

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…

Right-handers and left-handers have different representations of their own hand

1998

The visual control of our own hand when dealing with an object and the observation of interactions between other people's hand and objects can be involved in the construction of internal representations of our own hand, as well as in hand recognition processes. Therefore, a different effect on handedness recognition is expected when subjects are presented with hands holding objects with either a congruent or an incongruent type of grip. Such an experiment was carried out on right-handed and left-handed subjects. We expected that the different degree of lateralisation in motor activities observed in the two populations [J. Herron, Neuropsychology of left- handedness, Academic Press, New York…

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…

Assessing Virtual Reality as a Tool for Support Imagination

2002

One of the major developments of the second year of human life is the emergence of the ability to pretend (Leslie, 1987). Many children with autism use no pretend play or are impoverished in the quality of their play (Baron-Cohen, 1989). The key factor of our Virtual Reality Software in relation to Pretend Play is the possibility to really show the object transformations we propose when pretending. We hope those technics to drive people with autism to a better understanding of pretense and to enable them to develop a play with more quality.

Systematic, cognitive and historical approaches in musicology

1997

The aim of this paper is to discuss the relationship between systematic, cognitive and historical musicology. This will be done by outlining the historical and epistemological backgrounds, and comparing the methods and objects. It is argued that systematic and cognitive musicology have a common methodological background with a focus on the systematic way of conducting research. However, quite a lot of studies in cognitive musicology apply nonsystematic methods as well; even a historical approach to cognition is needed. The main tenet of this paper is that the backgrounds of cognitive and systematic musicology are sufficiently similar for a close and fruitful cooperation. However, because th…

The Third Way of Cognitive Science and the Middle Way of Buddhism

2013

Even though cognitive science may not be established as a mature science, being rather a loose affiliation of disciplines which make human cognition a scientific theme, it has already had significant impact in the field of epistemology. Since the late 1970s, research conducted on aspects of cognition ranging from perception to language has laid the groundwork for a fundamental epistemological shift in cognitive science, which bears directly on the Western philosophical dilemma of whether reality is objective (and independent of our cognition) or subjective (and so our mind’s projection). My aim here is to trace some major developments in the history of cognitive science leading to the emerg…

The Semantics of Musical Topoi

2015

The article introduces an empirical approach to studying music’s extrinsic meanings, based on the idea of musical topos as a set of musical entities that is delimited and furnished with meaning by extramusical associations in a listener population. The proposed methodology involves free, associative responses as well as responses on semantic variables addressing the imagery. After deriving potential topical structures for a given musical domain from the quantitative results, the structures are substantiated by using them to guide a rule-based, qualitative analysis of the free responses. The approach allows a view to the topical organization of a musical domain in which the identity of each …
