Abstract: This paper presents a novel deep learning based approach to solving arithmetic word problems . Solving different types of mathematical (math) word problems (MWP) is a very complex and challenging task as it requires Natural Language Understanding (NLU) and Commonsense knowledge . An application on this can benefit learning (education) technologies such as E-learning systems , Intelligent tutoring , Learning Management Systems (LMS), Innovative teaching/learning , etc. We propose Deep Learning based Arithmetic Word Problem Solver , DLAWPS, an intelligent MWP solver system. DLAWPS consists of a Recurrent Neural Network (RNN) based Bi-directional Long Short-Term Memory …(BiLSTM) to classify operation among four basic operations {+ , - , * , /}, and a knowledge-based irrelevant information removal unit (IIRU) to identify the relevant quantities to form an equation to solve arithmetic MWPs. Our system generates state-of-the-art results on the standard arithmetic word problem datasets –AddSub , SingleOp , and a Combined dataset. Show more

Abstract:  We tried to determine if emotive self-feedback from conscious assessment of artists’ own works generates sufficient impetus for accomplishment of goals. Self-reports from participants of an ‘experimental’ group working independently and without external feedback on their work are examined. The performance of this group is compared to ‘control’ performers in tutored sessions (with external feedback). On the whole a two-fold analysis was carried out. First, verbal reports of the participants’ feelings about their work in both experimental and control settings were analyzed. Second, a brainwave analysis of each participant was conducted while they were engaged in the …same tasks so as to examine effects of concentration and energy output. The Hilbert-Huang transform was used to filter data frequency for brainwaves emitted at channels AF4, AF3, F6 and F7, all positioned along the pre-frontal cortex. Results of participants’ brainwave behavior within frequency ranges of 14–16 Hz, as well as for higher ranges (above 60 Hz), do not show significant difference in the two groups. This indicates that brainwave activity is sustained in individuals who depend on self-feedback appraisals, at least within the domain of creativity investigated in this paper. Show more

Abstract: Currently, there is a great necessity in the organizations to support communication, collaboration, and coordination — important aspects that characterize collaborative systems—between its workers and enterprises; in order to simplify and improve their production processes. However, the development and maintenance of these systems are very complex. Although several proposals to develop them have been made, they usually lack theoretical models, which allow specifying and creating both group and interactive activities in a conceptual and formal way to sustain the requirements of group work. Therefore, this paper PRoposes an Ontological Model for developing collaboratIve SystEms (PROMISE), it tries to be a …guide for the analysis, design, and implementation of such systems in a formal, explicit manner. This model is based on an ontology, created using OWL (Web Ontology Language), providing a model of knowledge about in what way entities should be used and combined to control the execution of a set of orderly steps to develop these systems. Furthermore, this ontology has been validated through a set of academic’s projects, showing be great usefulness to developers. Show more

Abstract: Introduction Peripheral arterial disease (PAD) is a fairly common degenerative vascular condition in diabetic patients that leads to inadequate blood flow (BF), this disease is mainly due to atherosclerosis that causes chronic narrowing of arteries, which can precipitate acute thrombotic events. In patients with diabetes, atherosclerosis is the main reason for reducing life expectancy, as long as diabetic nephropathy and retinopathy are the largest contributors to end-stage renal disease and blindness, respectively. Objective This was an assessment of dilatation of the blood vessels on diabetic patients vs. healthy volunteers by using digital processing of imaging’s. Materials and Methods The study …subject was ultrasound imaging processing of blood vessels dilation on low extremities of diabetic patients, the results were compared with ultrasound images of healthy subjects. Results The digital images processing suggests that there is a significant difference among images experimental of the diabetic group and healthy volunteers’ images, the control group. Discussion The digital imaging processing performed in the Matlab platform is an adequate procedure for blood vessels dilation analysis of the ultrasound images taken from the lower extremities in diabetic patients.
