Innovative research technologies in the neurosciences have remarkably improved the perception of brain structure and function. The use of several neurofeedback training techniques is broadly used for the memory and cognition augmentation as well as for several learning difficulties and AHDD rehabilitation. Author's objective is to review cognitive enhancement techniques with the use of brain imaging intervention methods as well to evaluate the effects of these methods in the educational process. The efficiency and limitations of neurofeedback training with the use of EEG brain imaging, HEG scanning, namely NIR and PIR method and fMRI scan including rt-fMRI brain scanning technique are also discussed. Moreover, technical and clinical details of several neurofeedback treatment approaches were also taken into consideration.

Although learning disabilities studies is in advanced stage, research related in algorithmic procedures is limited, since interest in this field is recently displayed. This discourse describes some cognitive and algorithmic principles, which rule the development of a software related to dyscalculia. More specifically,this software design is based on principles related to the diagnostic evaluation of dyscalculia . The proposed software is based on the assumption that dyscalculia is noticed due to a lack of understanding of mathematical concepts and aims at understanding the cerebral reproductions of algorithmic procedures. One of the challenges is the analysis and evaluation the difficulties related to algorithmic mathematical thinking. A key point is maping the features of people with problems in algorithmic thinking.

Over the last few years, one major research direction of information retrieval includes user behaviour prediction. For that reason many models have been proposed aiming at the accurate evaluation of information retrieval systems and the best prediction of web search users' behaviour. In this paper we propose a new evaluation metric for information retrieval systems which employs two relevance factors; a relevance judgement grade and a popularity grade that represents users' vote for a document. We show that this new metric performs better than other evaluation metrics when expressing user behaviour. Moreover, in order to test the performance of our metric on different and scalable ranking algorithms, we develop a pairwise text similarity algorithm using cosine similarity, implemented on the MapReduce model, and then perform experiments on rankings generated by the algorithm.

Huntington's disease as a neurodegenerative disease is characterized by motor and cognitive impairment. The disease is caused by the mutation of the gene that produces the huntingtin protein causing the repetition of trinucleotide CAG. The mutant protein reacts with other proteins inside and out of the cell causing problems to its normal function and cell death. Recent advances in the signal analysis have engendered EEG with the status of a true brain mapping and brain imaging method able of providing spatio-temporal information regarding brain (dys)function. Authors aim to review objectively and quantitatively the neurophysiological basis of the disease in HD patients as compared to normal controls, with the use of brain imaging in general and EEG brain imaging methods.

ABSTRACT The evaluation of basic arithmetic algorithms has been until recently the core of mathematical tests in elementary and secondary education. However, it is necessary that students are able to understand, analyze and improve more complex algorithms in order to support further the study of mathematics and science. In this paper, a number of issues concerning algorithmic thinking are explored. In particular, a case study is proposed in order to compare the efficiency of the traditional algorithmic problem solving in relation to problem solving using interactive virtual environment. The findings suggest that when problem solving using interactive interface is used under conditions the results are more efficient comparing to the traditional way of algorithmic problem solving.

During the last decades, the interest displayed in neurocognitive and brain science research is relatively high. In this chapter, the cognitive neuroscience field approach focuses in the aspect of the way that cognitive functions are produced by neural circuits in the brain. Within this frame, the effects of impairment to the brain and subsequent changes in the thought processes due to changes in neural circuitry resulting from the ensued damage are analyzed and evaluated. All cognitive functions result from the integration of many simple processing mechanisms, distributed throughout the brain. Brain cortex structures, linked with cognitive disorders, are located in several parts like the frontal, the parietal, the temporal, the occipital lobe and more are analyzed and specified. A critical topic of this chapter in the evaluation of brain operations is mapping regions that control cognitive and mathematical concepts functions. Dyscalculia, in this chapter, is described as a specific...

Although studies on learning difficulties are in general in advanced stage, research related to algorithmic thinking difficulties is limited, since interest in this field has been recently expressed. Additionally, young people nowadays are familiarized with the use of computer. Therefore, an interactive computer-based diagnostic screener, referring to dyscalculia and algorithmic thinking difficulties, is proposed. In this paper, a number of issues concerning algorithmic thinking are also explored. In particular, an approach of algorithmic thinking definition is given and difficulties in algorithmic thinking features are studied. People facing algorithmic thinking difficulties have common characteristic therefore it would be crucial to discover the way these features could be identified in order to detect people at risk. Precise and analytical conclusions concerning the efficiency of the proposed screener are to be reached upon completion and review of the overall project phases.

The mathematical study of epidemics is essential for a better perception of their evolution and control potential. The typical deterministic mathematical models do not provide subjective modeling of these phenomena. The application of fuzzy set theory in order to model epidemiological problems and overcome this issue is suggested as an efficient predictive procedure for the epidemiology of infectious diseases. Although this is a recent research field, authors objective is to provide a review of the state of the art of fuzzy logic theory implementation in epidemiology. Findings suggest that fuzzy sets implementation in epidemiology is a really promising field of research and specify the future stages of fuzzy sets application in epidemiology.

Neurofeedback video games respond to electrical brain signals instead to a mouse, joystick, or game controller input. These games embody the concept of improving physiological functioning by rewarding specific healthy body signals with success at playing a video game. In this paper, a threefold framework in reference to attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) treatment blending with neurofeedback techniques and video game implementation is presented. In particular, the specifications of a neurofeedback-based video game for children dealing with ADHD, in order to enhance attention and concentration skills, are analyzed. Potential boundaries of this cognitive enhancement approach and authors future directions are also discussed.

Eight computer science students, novice programmers, who were in the first semester of their studies, participated in a field study in order to explore potential differences in their brain activity during programming with a visual versus a textual programming language. The students were asked to develop two specific programs in both programming languages (a total of four tasks). Measurements of cerebral activity were performed by the electroencephalography (EEG) imaging method. According to data analysis, it appears that the type of programming language did not affect the students' brain activity.

Although several surveys related to dyscalculia have proceeded so far, research seems to fail till now to develop a clear concept map referring to the features of dyscalculia classified according to age. Dyscalculia can be recognized by some specific features that are noticed through all stages of the individual’s development. In this paper a classification of features is proposed, according to individuals’ age as well as several screening methods, in order to ensure efficiency of the screening procedure. Dyscalculia’s features evaluation during different stages of age is crucial since diagnosis is relevant to the age considering that math’s learning difficulties arising in early ages are likely to be remitted since this status is possible to be temporary. An innovative aspect in this work is the citation and analysis of algorithmic thinking difficulties encountering in older ages under the range of learning difficulties in mathematics and dyscalculia.

Nowadays, Alzheimer's disease (AD) diagnosis is considered to be a crucial and extremely complex process. Nevertheless, psychometric tools, like Mini-Mental State Evaluation (MMSE), are used to address cognitive function assessment and clinical evaluation processes. However, MMSE's sensitivity in the diagnosis of mild cognitive impairment is debatable in terms of education, age, or nationality. Typical psychometric tools with the use of "paper and pencil" methods combined with physiology measurements are proposed in order to enhance validity and effectiveness in the case of Alzheimer's disease cognitive deficits. The objective of this review study is to highlight the effectiveness of brief cognitive tests (BCT) in the case of dementia and Alzheimer's disease screening. Authors' future work will focus on the application of BCT in MCI diagnosis and evaluation.

Nowadays, mobile devices are considered to be a powerful and portable tool for assisting people dealing with daily life issues. With the advance of mobile technology, the issue of mobile learning has been broadly explored in e-learning research. Several researchers and educators use pedagogical and technical strengths of mobile technology into learning environments. In this paper, an educational mobile-based application is described in order to promote Corfu’s Old town cultural heritage. The proposed educational mobile based application was pilot-tested in forty-five postgraduate students at Ionian University during cultural heritage courses. The students used a mobile-based educational environment in order to augment their heritage cultural perception and knowledge. The case study results suggest an enhanced perception of the educational content as well as a significantly increased acceptance of the education approach within the role of mobile technology in higher education.

Although significant advances have been made in understanding several cognitive states, the algorithmic thinking ability is yet to be analyzed in terms of neuroscience and brain imaging techniques. Studies on the effects of neurofeedback on learning disabilities especially mathematics disorders are limited. The objective of the present study is to evaluate the brain activity and activation differences between neurofeedback trained participants and controls, during the overall EEG analysis during continuous algorithmic tasks performance. A study of 182 children of upper education is proposed to assess the efficacy of two protocols of neurofeedback training as means of algorithmic thinking ability evaluation. Results suggest statistical significant variation in the mean SD values in terms of several brain waves ratios during algorithmic task solving epochs.

“Serious games” refer to games that go beyond pure entertainment and promote learning. They are utilized within a variety of learning environments enabling students to acquire knowledge and skills, while they offer wide benefits. The authors' team measured and analyzed various factors related to the gameplay and educational content when 2D and 3D serious games are introduced in the educational process. The main objective focused on the correlation of the University students' views that were sharing common characteristics, like gender, information and communication technology skills, game playing experience, and specific scientific background with factors that related to the gameplay as well as the learning effectiveness. The results revealed that game-playing experience had a more positive impact in the case of males, while perceived learning effectiveness of 2D was higher compared to the 3D serious game for both genders. Moreover, there are differentiations among females concerning the scientific background, Information and Communication Technology skills and game-playing experience.

The fusion of Artificial Neural Networks and Fuzzy Logic Systems allows researchers to model real
world problems through the development of intelligent and adaptive systems. Artificial Neural networks
are able to adapt and learn by adjusting the interconnections between layers while fuzzy logic inference
systems provide a computing framework based on the concept of fuzzy set theory, fuzzy if-then rules, and
fuzzy reasoning. The combined use of those adaptive structures is known as “Neuro-Fuzzy” systems. In
this chapter, the basic elements of both approaches are analyzed while neuro-fuzzy networks learning
algorithms are presented. Here, we combine the use of neuro-fuzzy algorithms with multimedia-based
signals for training. Ultimately this process may be employed for automatic identification of patterns
introduced in medical applications and more specifically for analysis of content produced by brain
imaging processes.

During the last decades, the interest displayed in neurocognitive and brain science research is relatively high. In this chapter, the cognitive neuroscience field approach focuses in the aspect of the way that cognitive functions are produced by neural circuits in the brain. Within this frame, the effects of impairment to the brain and subsequent changes in the thought processes due to changes in neural circuitry resulting from the ensued damage are analyzed and evaluated. All cognitive functions result from the integration of many simple processing mechanisms, distributed throughout the brain. Brain cortex structures, linked with cognitive disorders, are located in several parts like the frontal, the parietal, the temporal,
the occipital lobe and more are analyzed and specified. A critical topic of this chapter in the evaluation of brain operations is mapping regions that control cognitive and mathematical concepts functions.
Dyscalculia, in this chapter, is described as a specific disorder of managing and conceiving mathematical concepts. Dyscalculia could be identified by difficulties in visual perception, in spatial number organization, in basic mathematical operations and in mathematical induction logic. Moreover, people who deal with dyscalculia present problems, in Euclidean and Non-Euclidean Geometry concepts perception, in
Calculus aspects as well as in solving algorithmic problems where the design, the description and the application of algorithmic steps are required. In order to enhance cognitive brain functions perception, the use of EEG brain imaging is proposed measuring cerebral activity and event-related potentials. The procedure described in this chapter is about the comparison and contrasts EEG brain imaging patterns
of healthy volunteers to EEG samples taken of adults considered being at risk of mathematics learning disabilities such as Dyscalculia and algorithmic thinking difficulties. EEG interpretation analysis is to follow where the deviation of a normal and an abnormal range of wave’s frequency are defined. Several visualized
EEG patterns in relevance with specific abnormalities are presented while several neurocognitive generated disorders could be identified with the use of EEG Brain-imaging technique. The electroencephalogram EEG brain imaging procedure, in order to evaluate problems associated with brain function, is to be further analyzed in this chapter as well. The EEG is the depiction of the electrical activity occurring at the surface of the brain. The recorded waveforms reflect the cortical electrical
activity and they are generally classified according to their frequency (Delta, Theta, Beta, Alpha, Beta, and Gamma) amplitude, and shape. EEG Implementation with the use of 10/20 system of the standardized position of scalp electrodes placement for a classical EEG recording is described as well.
The EEG implementation objective is to identify, classify and evaluate those frequencies and regions in the brain that best characterize brain activity associated with mathematical learning disabilities. Mapping the brain with non-invasive techniques based on trigger and sensing/evaluation experimental multimedia methods similar to those used in computer games and applications are expected to provide relevant results in order to enhance and confirm theoretical cognitive aspects. At that point, a cognitive and mathematical perception evaluation is to follow and specifically the assessment of the relation of difficulties in mathematics with particular parts of the human brain. EEG wave data visualization is contacted with the use of Acknowledge an interactive, intuitive program which provides data analysis instantly. At the end of this chapter EEG computational evaluation with the use of pattern recognition methods as well as the intuition of author’s future work in relevance with the use of experimental multimedia technologies to enhance the dynamic recognition and evaluation of user cognitive responses during EEG implementation are noted.

As Internet develops rapidly huge amounts of texts need to be processed in a short time. This entails the necessity of fast, scalable methods for text processing. In this paper a method for pairwise text similarity on massive data-sets, using the Cosine Similarity metric and the tf-idf (Term Frequency-Inverse Document Frequency) normalization method is proposed. The research approach is mainly focused on the MapReduce paradigm, a model for processing large data-sets in parallel manner, with a distributed algorithm on computer clusters. Through MapReduce model application on each step of the proposed method, text processing speed and scalability is enhanced in reference to other traditional methods. The CSMR (Cosine Similarity with MapReduce) method’s implementation is currently at the implementation stage. Precise and analytical conclusions concerning the efficiency of the proposed method are to be reached upon completion and review of the overall project phases

"Taboo-Transgression-Transcendence in Art & Science" started as a wish to explore three different levels of conception and perception of the aesthetics and ethics in the field of art & science. During its maturing process the project developed towards the exploration of the line where art and science meet and therefore also the border where they divide. The three "T" initials condensate three ideas. First the forbidden, a convention that is so deeply rooted that few seem to be willing to break it. Second the defiance, the challenge to the convention itself either through the resistance to execute an order or through the direct action against the status quo. Third, the sublimation, the transition to an alternative state that overcomes the expected intermediary stages in linear conceptualization, here connected with the expansion of limits.
