Application of learning pallets for real-time scheduling by the use of radial basis function network
2013
The expansion of the scope and scale of products in the current business environments causes a continuous increase in complexity of logistics activities. In order to deal with this challenge in planning and control of logistics activities, several solutions have been introduced. One of the most latest one is the application of autonomy. The paradigm of autonomy in inbound logistics, can be reflected in decisions for real-time scheduling and control of material flows. Integration of autonomous control with material carrier objects can realize the expected advantages of this alternative into shop-floors. Since pallets (bins, fixtures, etc.) are some common used carrier objects in logistics, t…
The cognitive neuropsychology of recollection
2013
The recognition of whether someone, something or somewhere has been experienced before rests on a decisionmaking process. In humanmemory, information is not reproduced as it would be in a computer, but is a reflective, conscious process. This is more so the case when encountering the same scene, environment or idea for a second time. When we recognize something as having been encountered before we arguably make a comparison between what is represented in the cognitive system and what is currently perceived. Consider that somebody uses the word ‘loquacious’, a word which you have only just encountered recently, and up until then, you did not know its meaning, or even existence. When encounte…
Subjective Experience of Episodic Memory and Metacognition: A Neurodevelopmental Approach
2013
Episodic retrieval is characterized by the subjective experience of remembering. This experience enables the co-ordination of memory retrieval processes and can be acted on metacognitively. In successful retrieval, the feeling of remembering may be accompanied by recall of important contextual information. On the other hand, when people fail (or struggle) to retrieve information, other feelings, thoughts and information may come to mind. In this review, we examine the subjective and metacognitive basis of episodic memory function from a neurodevelopmental perspective, looking at recollection paradigms (such as source memory, and the report of recollective experience) and metacognitive parad…
Lie Detection: Remarks From Neuroethics
2016
El presente trabajo aborda los aspectos bioéticos derivados de los ya no tan recientes avances en Neurociencia cognitiva; especialmente las implicaciones que la introducción de las pruebas neurocientíficas en el proceso judicial penal, como la conocida técnica de detección de mentiras (prueba P.300) pueden acarrear. Como seguidamente veremos, el creciente desarrollo de la neuroimagen ha avivado la inquietud por la protección de la autonomía individual, la seguridad y la superación de interpretaciones reduccionistas contrarias a la dignidad de las personas. Cuestiones a las que están prestando atención los estudios de neuroética, los cuales, aunque empezaron su recorrido a finales de la déca…
Register affects language comprehension: ERP evidence from article omission in newspaper headlines
2011
Abstract Language processing involving syntax-discourse interface operations has been claimed to be particularly resource-consuming. In production, this additional complexity is claimed to be the source of article omission in the speech of young children and certain language-impaired speakers. In comprehension, article omission in some “special registers” (e.g., newspaper headlines) has been attributed to the trade-off between spending more processing resources and increasing processing speed. We investigated the comprehension of noun phrases (NPs) with and without articles (e.g., (a) policeman arrests (a) monk) when readers were or were not aware of reading headlines by recording electroph…
Conceptualization of relative size by honeybees
2014
The ability to process visual information using relational rules allows for decisions independent of the specific physical attributes of individual stimuli. Until recently, the manipulation of relational concepts was considered as a prerogative of large mammalian brains. Here we show that individual free flying honeybees can learn to use size relationship rules to choose either the larger or smaller stimulus as the correct solution in a given context, and subsequently apply the learnt rule to novel colors and shapes providing that there is sufficient input to the long wavelength (green) photoreceptor channel. Our results add a novel, size-based conceptual rule to the set of relational conce…
Grasp-specific motor resonance is influenced by the visibility of the observed actor
2016
AbstractMotor resonance is the modulation of M1 corticospinal excitability induced by observation of others' actions. Recent brain imaging studies have revealed that viewing videos of grasping actions led to a differential activation of the ventral premotor cortex depending on whether the entire person is viewed versus only their disembodied hand. Here we used transcranial magnetic stimulation (TMS) to examine motor evoked potentials (MEPs) in the first dorsal interosseous (FDI) and abductor digiti minimi (ADM) during observation of videos or static images in which a whole person or merely the hand was seen reaching and grasping a peanut (precision grip) or an apple (whole hand grasp). Part…
Non-cognate translation priming effects in the same–different task: evidence for the impact of “higher level” information
2015
Norris and colleagues have proposed that priming effects observed in the masked prime same–different task are based solely on pre-lexical orthographic information. This proposal was evaluated by examining translation priming effects from non-cognate translation equivalents using both Spanish–English and Japanese–English bilinguals in the same–different task. Although no priming was observed for Spanish–English bilinguals, who also produced very little translation priming in a lexical decision task, significant priming was observed for Japanese–English bilinguals. These results indicate that, although most of the priming in the same–different task has an orthographic basis, other types of pr…

A Neural Architecture for Segmentation and Modelling of Range Data
2003
A novel, two stage, neural architecture for the segmentation of range data and their modeling with undeformed superquadrics is presented. The system is composed by two distinct neural stages: a SOM is used to perform data segmentation, and, for each segment, a multi-layer feed-forward network performs model estimation. The topology preserving nature of the SOM algorithm makes this architecture suited to cluster data with respect to sudden curvature variations. The second stage is designed to model and compute the inside-outside function of an undeformed superquadric in whatever attitude, starting form the (x, y, z) data triples. The network has been trained using backpropagation, and the we…
