Dynamic Is-a Hierarchy Generation based on Viewpoints

Is-a hierarchies form the foundation of ontologies. That is, is-a hierarchies in an ontology reflect how the ontology captures the essential conceptual structure of the target world. Therefore, in ontological theories, an is-a hierarchy should be single-inheritance because the essential property of things cannot exist in multiple. However, we cannot avoid multi-perspective issues when we build an ontology because the user often want to understand things from their own viewpoints. In order to tackle this multi-perspective issue, the authors take an approach of dynamically generating is-a hierarchies according to the viewpoints of users from an ontology using single-inheritance. This article discusses a framework for dynamic is-a hierarchy generation with ontological consideration on is-a hierarchies generated by it. Then, the author shows its implementation as a new function of Hozo and its applications to a medical ontology for dynamically generation of is-a hierarchies of disease. Through the function, users can understand an ontology from a variety of viewpoints. As a result, it could contribute to comprehensive understanding of the ontology and its target world.
The Attachment Relationship with Emotional Intelligence and Well-Being

Introduction: In personality development, attachment experiences are critical for human emotional and cognitive development. Interactions with attachment figures are important for the shaping of individuals’ self-image and social world, which are internalized in an internal working model (Bowlby, 1969/1982), based on affective and cognitive representations of self, others, and relationships, which affect individuals’ close relationships and emotion regulation throughout their lifespan. Attachment theory has become, also, one of the most influential perspectives through we understand the emotional regulation. Onjectives: This study examines the relations between self-reported adult attachment orientation, self-esteem, emotional intelligence development and well-being. This study show the correlations between the types of adult attachment, emotional intelligence and self-esteem, and how these dimensions determine the adoption of emotion regulation strategies, attachment theory becoming one of the most influential perspectives through we understand the emotional regulation and social interaction as adult. Methods: 75 romanian adults were evaluated with Adult Attachment Scale (Collins & Read, 1990), Global Self-Esteem Scale (Rosenberg, 1965), Emotional Intelligence Test (adapted M. Roco by Bar-On, 1997) and Self-report Well-Being Questionnaire (Nanu, 2014). The results show the secure attachment is significative positive correlation with self-esteem, emotional intelligence and well-being. Results: Results reveal correlations between the types of adult attachment, self-esteem level, emotional intelligence development and subjective well-being. Results confirm conclusions of the other studies: Bartholomew and Horowitz (1991) link between attachment, self-esteem and sociability, Wayne, Cozzarelli & Nebi (2010) or Xu Li & Xue Zheng, (2014) – explore emotional intelligence and self-esteem as mediators of the relationship between adult attachment orientations and subjective well-being. Conclusions: We hope that the results of this study will garner sufficient interest among attachment researchers and practitioners, to generate further investigations to the function of attachment involved in well-being.
Detecting skin colors under varying illumination

Skin color has been used as an important cue for various human related computer vision applications. However, detecting skin colors under varying illumination is a challenging task, as the appearance of skin in an image highly depends on the illumination under which the image was taken. To this end, a method for detecting skin colors under varying illumination is proposed in this paper. First, spatial illumination variation is identified and the images are segmented into different regions with different illumination. Each illumination region of color images are corrected base on the illuminant estimated by a local edge-based color constancy algorithm. Then, the corrected images are transformed into a color-space, where statistical results on a skin dataset show that the skin color cluster and non-skin color clusters are separated. Finally, the skin colors are modeled under Bayesian decision framework and classified from non-skin colors. The experimental results show that the proposed method is robust to illumination variations.
Can computer vision assist creativity?

Computer vision techniques have been used extensively for 3D object recognition in many industrial applications such as robotics or automatic inspection. Very few attempts have explored the possibility of applying these techniques to 3D creative design. This paper discusses how requirements for creative design differ from those for other applications. Relevant computer vision techniques are identified, and a system which is suitable for creative design is proposed.
Mechanical Engineering 6-4-2019 Encoding Invariances in Deep Generative Models

Reliable training of generative adversarial networks (GANs) typically require massive datasets in order to model complicated distributions. However, in several applications, training samples obey invariances that are \textit{a priori} known; for example, in complex physics simulations, the training data obey universal laws encoded as well-defined mathematical equations. In this paper, we propose a new generative modeling approach, InvNet, that can efficiently model data spaces with known invariances. We devise an adversarial training algorithm to encode them into data distribution. We validate our framework in three experimental settings: generating images with fixed motifs; solving nonlinear partial differential equations (PDEs); and reconstructing two-phase microstructures with desired statistical properties. We complement our experiments with several theoretical results.

INVESTIGATION OF THE RELATION BETWEEN UNIFIED PARKINSON DISEASE RATING SCALE ( UPDRS ) AND BALANCE SCORES IN PATIENTS WITH IDIOPATHIC PARKINSON ’ S DĠSEASE

The aim of the study was to investigate the relation between unified parkinson disease rating scale (UPDRS) and balance scores in patients with idiopathic Parkinson’s disease. 15 patients; 11 female and 4 male with the diagnosis of idiopathic Parkinson’s disease were included in the study. The mean age was 68.00±9.44 years and mean disease duration was 3.36±0.71 years. Patients were evaluated with UPDRS, forward and lateral functional reach tests. As a result of statistical analysis, no significant relation were determined between UPDRS’s sub and total scores and forward functional reach test. (p>0.05). There was significantly high correlation between UPDRS’s activities of daily living, motor and total scores and lateral functional reach test (r= -.768, p<0.01_ r= -.696, p<0.05 and r= -.793, p<0.01). As a result of the study, it was concluded that lateral functional reach test is a practical and useful method for determining the functional level of the patients and the effects of therapeutic applications in patients with idiopathic Parkinson’s disease. Similar studies are needed to be performed in different types of parkinson’s diesease.
Cochannel Interference Suppression in the Single Antenna Amplify-and-Forward Relay Networks

We consider an amplify-and-forward relay system with a source node (S), a relay node (R), and a destination node (D) with an arbitrary number of cochannel interferers at the relay. Each node is equipped with a single antenna and operates under the frequency selective circumstance. For such a system, we propose a system scheme to suppress the relay cochannel interference (CCI) at both the relay and the destination, where the relay performs noise selective nulling in the training block to make the relay training sequence avoid suffering from the thermal noise and CCIs at R, and the destination combines the data blocks from the S→R→D link and the S→D link. Simulation results show that the proposed system scheme achieves better channel estimation and symbol detection performance than the original one.
Hadamard transform image coding

The introduction of the fast Fourier transform algorithm has led to the development of the Fourier transform image coding technique whereby the two-dimensional Fourier transform of an image is transmitted over a channel rather than the image itself. This devlopement has further led to a related image coding technique in which an image is transformed by a Hadamard matrix operator. The Hadamard matrix is a square array of plus and minus ones whose rows and columns are orthogonal to one another. A high-speed computational algorithm, similar to the fast Fourier transform algorithm, which performs the Hadamard transformation has been developed. Since only real number additions and subtractions are required with the Hadamard transform, an order of magnitude speed advantage is possible compared to the complex number Fourier transform. Transmitting the Hadamard transform of an image rather than the spatial representation of the image provides a potential toleration to channel errors and the possibility of reduced bandwidth transmission.
Bridging the Gap: Improving Students' Learning Experience through Shifting Pedagogical Practices in Higher Education

Curriculum modelling is a necessary pedagogical practice for teachers in higher education and appropriately designed curricula has the potential to reinvigorate student learning. Learning goals established collaboratively and sequentially across different courses in a program’s curriculum contribute to an assurance of learning (AOL) and involve students in quality teaching and learning experiences. If learners respond to explicit teaching how do we prepare students for the demands of professional practice? This paper describes the process of curriculum modelling that relies on the matching of professional standards (set by industry accreditation bodies) with University graduate attributes (set by the institution). In traditional curriculum design these two non-negotiable aspects are aligned with individual course outcomes, learning and teaching activities and assessment. It is proposed that embedding eLearning across curricula will ensure students engage appropriately with technology. One example is embedding reflection tasks into assessment and using an ePortfolio to document a student’s learning journey.

Model Analysis Using Statistical Screening : Extensions and Example Applications 1

System dynamics models are often constructed to improve system performance by identifying and modifying feedback mechanisms that drive system behavior. Once identified, these feedback mechanisms can be used to design and test policies for system performance improvement. A preliminary step in developing policies is the identification of high leverage parameters and structures, the influential model sections that drive system behavior. The current work clarifies and extends the use of statistical screening (Ford and Flynn, 2005) as a model analysis tool with a six step process that identifies specific model sections for further analysis and development. The work also presents a method that clarifies the results of model analysis with statistical screening to practicing managers. Example application to three models, including the tipping point model (Taylor and Ford 2006, 2007) Bass diffusion (Sterman 2000), and World3 model (Meadows et al. 1974), illustrate the use of the tool and method. Statistical screening offers system dynamicists a userfriendly tool that can be used to help explain how model structure drives system behavior.
Broadcasting in the New Millennium: A Prediction

The paper is an attempt to predict the Broadcasting in the new millennium keeping in view it's new role, the technological development, convergence, the impact of multimedia, computer, Internet on Radio and TV. The paper predicts that the prospect of digital and new delivery systems does not imply the ‘death of traditional broadcasting’. Broadcast transmissions will, of course, eventually become digital, but analogue services will continue for another 20 years, with “Plain Old Radio” continuing to be the heart of broadcasting. It further suggests that broadcasting will be a part of Global Information Infrastructure (GII) and National Information Infrastructure (NII) and will not exist in isolation. The broadcast organizations have to completely reorganize to be globally competitive and also to cater to its new role.
Improvement of distributed control algorithms for robots carrying an object

We consider the problem of moving a pair of omnidirectional robots carrying a ladder between start and goal positions in an obstacle-free plane as quickly as possible, using a distributed algorithm in which each robot decides its motion individually. In this paper we propose a modification to an existing algorithm for this problem and examine the performance of the resulting algorithm by computer simulation. The simulation results indicate that the resulting algorithm performs better in terms of time than previous algorithms in certain situations, and nearly as well in most other cases.
Forecasting Volatility Switching Arch by treed gaussian process with Jumps to the Limiting Linear Model

Abstract In this paper, we propose a new hybrid model of asymmetric volatility by using treed Gaussian process with jumps to the limiting linear model (TGPLLM) of Gramacy and Lee combined with the volatility switching ARCH (VS-ARCH) developed by Fornari and Mele to model and predict stock market volatility. Nonparametric sensitivity analysis based on the TGPLLM is applied to check the relevance level of five input variables in the model. Meanwhile, support vector machine is also employed to obtain another new hybrid model for making a comparison with the former. Empirical analysis of NASDAQ index reveals that the five input variables are all significant; the hybrid model based on TGPLLM yields better predictive performance than the ones based on SVM, the parametric models of VS-ARCH, ARMA-GARCH and ARMA-GJR models.
maritime expansion in the 19 th century : Existing explanations and some new explorations

The Norwegian merchant fleet expanded dramatically during the second and third quarter of the nineteenth century. Between 1850 and 1880 alone, the size of the fleet increased more than fivefold, making it the fastest expanding fleet in the world and reaching the position as the third largest fleet in the world by 1880 in terms of tonnage. The growth in registered tonnage reflected an increasing orientation towards international freight markets by Norwegian ship-owners: In 1875, 78 percent of the earnings made from the fleet was accumulated in cross-trades, and this expansion made shipping the largest export earner in the Norwegian economy, accounting for approximately 30 to 40 percent of export incomes in the period from 1835 to 1970.
Compressed Spectrum Sensing for Whitespace Networking

We study the problem of wideband compressed spectrum sensing for detection of whitespaces when some prior knowledge about spectrum occupancy is available. Our experiments show that the primary user occupancy of the UHF band at a given location doesn’t vary much with time. Thus, from initial sensing we estimate the support of spectrum occupancy and we use this knowledge in subsequent sensing. We explore two methods in this regard. However, the above methods still require spectrum recovery which has high complexity but since we are interested in only detection, we pose the detection problem directly on the compressed samples (thereby avoiding recovery) assuming i.i. d flat fading between the primary users, and analyse its performance.
C O ] 3 J an 2 01 9 Directed Plateau Polyhypercubes

In Z2, a polyomino is a finite union of cells (unit squares), connected by their edges, without a cut point and defined up to a translation [5]. Polyominoes appear in statistical physics, in the phenomenon of percolation [14]. The number of polyominoes in general is still an open problem. Polyhypercube are the extension of polyominoes in a dimension d ≥ 3 [1]. In Z, a polyhypercube of dimension d is a finite union of cells (unit hypercubes), connected by their hypercubes of dimension d − 1, and defined up to translation [7]. Polyhypercubes are also called d-polycubes. They are used in an efficient model for real time validation [12] and in representation of finite geometric languages [8]. There is no explicit formula for Ad(n) the number of polyhypercubes in dimension d with n cells. Many algorithms were made and values are given for many dimensions (see [1][13]). Some families of polyhypercubes were enumerated for instance: the directed plateau, the plateau, the espalier and the pyramid polyhyercubes by the hypervolume and width using Dirichlet convolutions [6]. Also, the generating function and asymptotic results were given for the rs-directed [9], polyhypercubes that can be split into directed strata. Also for d = 3, called polycubes, the directed plateau and the plateau polycubes were enumerated according to the lateral area [2]. In this paper, we introduce a new parameter: the lateral area of a polyhypercube for a dimension d ≥ 3. Using this parameter and the width, we enumerate the family of directed plateau polyhypercubes.
Effect of metformin on cardiac function in patients with STEMI : a systematic review and meta-analysis

Background and aim: Metformin may have the potential in improving cardiac function in patients with ST-elevation myocardial infarction (STEMI). However, the results remain controversial. We conducted a systematic review and meta-analysis to explore the effect of metformin on cardiac function of patients with STEMI. Methods: PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of metformin versus placebo on cardiac function of patients with STEMI were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. Meta-analysis was performed using the random-effect model. Results: Four RCTs involving 1366 patients were included in the meta-analysis. Overall, compared with control intervention in nondiabetic patients with STEMI, metformin treatment was found to significantly reduce LVEF (MD = -1.70; 95% CI = -1.71 to -1.69; P<0.00001), and increase LVEDV (MD = 0.50; 95% CI = 0.43 to 0.57; P<0.00001) and LVESV (MD = 3.80; 95% CI = 3.74 to 3.86; P<0.00001), but demonstrated no influence on NT-proBNP (MD = -1.90; 95% CI = -35.90 to 32.10; P = 0.91), creatinine (MD = -0.23; 95% CI = -2.09 to 1.62; P = 0.81), and HbA1c (MD = 0.00; 95% CI = -0.05 to 0.05; P = 1.00). Conclusions: Compared to control intervention non-diabetic patients with STEMI, metformin treatment significantly reduced LVEF, and improved LVEDV as well as LVESV, but had no influence on NTproBNP, creatinine and HbA1c.
Evaluation of Incidental Thyroid Findings Detected by Positron Emission Tomography/Computed Tomography

Background: Thyroid incidenteloma detected on 18FFDG PET/CT carries a high risk of malignancy. This high risk of malignancy supports the performance of a further diagnostic procedure, such as ultrasonography and fine needle aspiration biopsy. Aim of Study: To determine the role of PET/CT in evaluation of incidental thyroid lesions detected in patients being studied for lymphomas and/or cancers other than of thyroid. Material and Methods: This study included thirty four patients with incidental abnormal increased FDG uptake. All patients were subjected to ultrasound examination and patients with focal increased tracer uptake were subjected to fine needle aspiration biopsy. Results: This study included a total of 1263 consecutive patients who underwent a FDG PET/CT study for staging of an advanced cancer of any site of the body other than the thyroid gland during the period. An incidental abnormal increase in FDG uptake in the thyroid gland was observed in 39 (3.08%) patients. Out of these patients, 26/39 (66.6%) presented with a focal and 13/39 (33.4%) with a diffuse thyroid uptake giving a prevalence of 2.06% for focal uptake and 1.03% for diffuse uptake. Six patients out of 23 patients with focal abnormal thyroid uptake were proven to have thyroid malignancy (Four patients with papillary thyroid carcinoma, one patient with follicular thyroid carcinoma and the remaining patient with atypical Hurthle cells). Thus the malignancy rate in patients with thyroid incidentalomas which proceeded to tissue biopsy was about 26%. Conclusion: An incidental focal uptake of 18F-FDG in the thyroid gland is of significant risk of malignancy. A high value of SUVmax increases the risk of malignancy and SUVmax does not correlated with the diameter of malignant lesions, so FDG-PET/CT can detect malignancy in small thyroid lesions.
