Numerical simulation of the flow around two side by side circular cylinders by IVCBC vortex method

A novel two dimensional pure Lagrangian vortex method based on instantaneous vorticity conserved boundary conditions (IVCBC) has been applied to investigate the hydrodynamic coefficients and patterns flow around two circular cylinders in side by side arrangements with pitch ratios T D =1.1 7 at a high Reynolds number Re =6x10 4 The benchmark case of viscous flow around a circular cylinder was first carried out to validate the novel vortex method. Then simulations of the flow around two side by side circular cylinders were performed. A new scheme was proposed to distinguish the wide wake (WW) and narrow wake (NW) by judging the velocity direction of a specific point in the gap flow. The hydrodynamic coefficients and Strouhal numbers were thoroughly studied as a function of the pitch ratios. A total of five kinds of flow patterns were identified. During the investigation of biased flow, an intermediate frequency between frequencies of NW and WW was found and approached to that of a single cylinder. The results show good agreement with the previously published experimental and numerical data.
Experimental study on flow around an array of four circular cylinders
Venue: 2016 Techno Ocean (Techno Ocean)

Experiments were carried out in a towing tank regarding the flow around a stationary array of circular cylinders with low aspect ratio, H/D=1.5, piercing the water free surface. One isolated cylinder and one array of 4 cylinders were tested; this number of cylinders corresponds to the number of the columns of the typical multi column offshore floater system, as semi submersibles and TLP platforms. The aims are to create a reliable database for CFD studies and to better understand the influence of the relative position of the cylinders on the flow around this type of structure and afterward to use this research in VIM calculations for free multi columns systems. Two parameters were investigated: distance between column centers, S/D 2, 3 and 4; and current incidence angle, 0, 22.5 and 45 degrees. The Reynolds number range covers 50,000 up to 250,000. Forces were measured in each column using a three degree of freedom load cell. Results of lift and drag forces are presented for each column separately and for the whole system.
Biodiversity responses to vegetation structure in a fragmented landscape: ant communities in a peri urban coastal dune system
Venue: Journal of Insect Conservation

Habitat fragmentation often results in significant degradation of the structure and composition of remnant natural vegetation, leading to substantial biodiversity decline. Ants are an ecologically dominant faunal group known to be sensitive to vegetation degradation following fragmentation. We examined ant diversity and composition in relation to changes in vegetation structure in remnant coastal vegetation in the global biodiversity hotspot of southwestern Western Australia. The key features of vegetation structure driving the species and functional diversity and composition of ant communities were measures of cover of vegetation and bare ground. However, these effects were highly idiosyncratic at the species level. Cluster analyses based on plant species composition classified plots into two groups corresponding to relatively intact and degraded vegetation respectively. Although systematic changes in plant diversity and vegetation structure were observed between the two groups, key features from an ant perspective (native plant cover and bare ground) remained unchanged. Vegetation degradation consequently had little overall effect on ant species composition and functional diversity. The major disturbance related impact on ant communities was through invasion by exotic ants, especially Pheidole megacephala; however, this occurred only in close proximity to development. Our results suggest that the priority for conserving ant diversity in our coastal dune system is the prevention of invasion by exotic species.
Aspect based Opinion Summarization with Convolutional Neural Networks
Venue: 2016 International Joint Conference on Neural Networks (IJCNN)

This paper studies Aspect based Opinion Summarization (AOS) of reviews on particular products. In practice, an AOS system needs to address two core subtasks, aspect extraction and sentiment classification. Most existing approaches to aspect extraction, using linguistic analysis or topic modeling, are general across different products but not precise enough or suitable for particular products. Instead we take a less general but more precise scheme, which directly maps each review sentence into pre defined aspects. To tackle aspect mapping and sentiment classification, we propose two Convolutional Neural Network (CNN) based methods, cascaded CNN and multitask CNN. Cascaded CNN contains two levels of convolutional networks. Multiple CNNs at level 1 deal with aspect mapping task, and a single CNN at level 2 deals with sentiment classification. Multitask CNN also contains multiple aspect CNNs and a sentiment CNN, but different networks share the same word embeddings. Experimental results show that both cascaded and multitask CNNs with pre trained word embedding outperform linear classifiers, and multitask CNN generally performs better than cascaded CNN.
Aspect based Opinion Summarization for Disparate Features

Significant advancement in e commerce has led to the invention of several websites selling products online. These websites also facilitate the buyers to express their opinions about the products their features in the form of reviews. Knowing these opinions and the related sentiments plays an important role in decision making processes involving regular customers to executive managers. But these reviews are available in huge numbers hence referring them becomes a practically impossible task to achieve. Thus a new orientation called Opinion Mining Summarization has emerged to deal with the problem. Aspect based (Feature based) Opinion Summarization is one of these summarization techniques which provide brief yet most relevant information about different features related to the target product. Hence the approach is in great demand nowadays because it exactly shows what a customer usually tries to search while referring the reviews. This paper focuses on extraction of different kinds of features associated with a target entity. Current state of the art suggests that concrete techniques are highly required for identification of those features which are not clearly mentioned. Thus our prime target is to deliver a succinct solution for effective identification of implicit features along with the explicit ones based on the opinion words encountered in user reviews. This is achieved by first extracting and processing the explicit features and then using them for the identification of implicit features. Finally summarization of sentences containing both kinds of aspects is done.

Medical Waste Disposal Method Selection Based on a Hierarchical Decision Model with Intuitionistic Fuzzy Relations
Venue: International journal of environmental research and public health

Although medical waste usually accounts for a small fraction of urban municipal waste, its proper disposal has been a challenging issue as it often contains infectious, radioactive, or hazardous waste. This article proposes a two level hierarchical multicriteria decision model to address medical waste disposal method selection (MWDMS) where disposal methods are assessed against different criteria as intuitionistic fuzzy preference relations and criteria weights are furnished as real values. This paper first introduces new operations for a special class of intuitionistic fuzzy values, whose membership and non membership information is cross ratio based ]0, 1[ values. New score and accuracy functions are defined in order to develop a comparison approach for ]0, 1[ valued intuitionistic fuzzy numbers. A weighted geometric operator is then put forward to aggregate a collection of ]0, 1[ valued intuitionistic fuzzy values. Similar to Saaty's 1 9 scale, this paper proposes a cross ratio based bipolar 0.1 0.9 scale to characterize pairwise comparison results. Subsequently, a two level hierarchical structure is formulated to handle multicriteria decision problems with intuitionistic preference relations. Finally, the proposed decision framework is applied to MWDMS to illustrate its feasibility and effectiveness.
Design and analysis of single phase voltage source inverter using Unipolar and Bipolar pulse width modulation techniques
Venue: 2016 International Conference on Advances in Electrical, Electronic and Systems Engineering (ICAEES)

This research work is organized in two sections. Performance comparison of single phase half bridge inverter and single phase full bridge inverter is done in the first section. It is observed the output current and output voltage of full bridge inverter is twice and generates less total harmonic distortion as compared to half bridge inverter. In the second section, performance comparison of Unipolar and Bipolar PWM is presented for single phase full bridge inverter with and without filter in MATLAB SIMULINK. The proper choice of Frequency Modulation Ratio (mf) is discussed in detail for bipolar and unipolar PWM scheme. Non integer value of mf results in sub harmonics which are nearly unfilterable and cause significant losses in any power system application. It is observed that Unipolar PWM has an advantage in terms of efficiency; it offers less switching losses and generates less EMI. Also, the switching frequency becomes twice and voltage amplitude is reduced to half in case of unipolar PWM. Therefore, total harmonic distortion (THD) content of output current and output voltage is decreased, thus improving the power quality and making filter easier.

Venue: 2016 17th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM)

This paper presents a novel space vector pulse width modulation strategy for a single phase three level buck boost inverter based on an impedance source network. The case study system is based on T source inverter with continuous input current. To demonstrate the improved performance of the inverter, the strategy was compared the traditional pulse width modulation. It is shown that the approach proposed has fewer switching states and does not suffer from neutral point misbalance.
Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations

The protection of Controlled Unclassified Information (CUI) resident in nonfederal systems and organizations is of paramount importance to federal agencies and can directly impact the ability of the federal government to successfully conduct its essential missions and functions. This publication provides agencies with recommended security requirements for protecting the confidentiality of CUI when the information is resident in nonfederal systems and organizations; when the nonfederal organization is not collecting or maintaining information on behalf of a federal agency or using or operating a system on behalf of an agency; and where there are no specific safeguarding requirements for protecting the confidentiality of CUI prescribed by the authorizing law, regulation, or governmentwide policy for the CUI category listed in the CUI Registry. The requirements apply to all components of nonfederal systems and organizations that process, store, or transmit CUI, or that provide security protection for such components. The requirements are intended for use by federal agencies in contractual vehicles or other agreements established between those agencies and nonfederal organizations.
Towards a sustainable interoperability in networked enterprise information systems: Trends of knowledge and model driven technology
Venue: Comput. Ind.

Sustaining interoperability in enterprise networks is the next research challenge.Not understanding the impact of a single system change may cause network failures.Pervasive information models and EA can support dynamic interoperability enablers.Combined use of model driven and knowledge based approaches can improve NG EIS.We present and discuss the sustainable interoperability research framework. In a turbulent world, global competition and the uncertainty of markets have led organizations and technology to evolve exponentially, surpassing the most imaginary scenarios predicted at the beginning of the digital manufacturing era, in the 1980s. Business paradigms have changed from a standalone vision into complex and collaborative ecosystems where enterprises break down organizational barriers to improve synergies with others and become more competitive. In this context, paired with networking and enterprise integration, enterprise information systems (EIS) interoperability gained utmost importance, ensuring an increasing productivity and efficiency thanks to a promise of more automated information exchange in networked enterprises scenarios. However, EIS are also becoming more dynamic. Interfaces that are valid today are outdated tomorrow, thus static interoperability enablers and communication software services are no longer the solution for the future. This paper is focused on the challenge of sustaining networked EIS interoperability, and takes up input from solid research initiatives in the areas of knowledge management and model driven development, to propose and discuss several research strategies and technological trends towards next EIS generation.
A Rare Cause of Metabolic Acidosis: Fatal Transdermal Methanol Intoxication in an Infant.
Venue: Pediatric emergency care

Oral methanol intoxication is common, but dermal intoxication is rare. We report a previously healthy 19 month old female infant admitted to the emergency department (ED) with vomiting and tonic clonic seizure. On physical examination, she was comatose and presented signs of decompensated shock with Kussmaul breathing. Her left thigh was edematous, with purple coloration. Methanol intoxication was suspected due to high anion gap metabolic acidosis (pH, 6.89; HCO3, <3 meq/L) and exposure to spirit soaked bandages %96 methanol) for 24 hours and 3 days. The patient's serum methanol level was 20.4 mg/dL. She was treated with fomepizole and continuous venovenous hemodialysis (CVVHD) in the pediatric intensive care unit, and methanol levels decreased to 0 mg/dL after 12 hours. During follow up, massive edema and subarachnoid hemorrhage in the occipital lobe were detected by computed tomography of the brain. The patient died after 7 days.Although methanol intoxication occurs predominantly in adults, it must be considered in children with high anion gap metabolic acidosis. This case report demonstrates that fatal transdermal methanol intoxication can occur in children, and it is the second report in the English literature of transdermal methanol intoxication in an infant.
Understanding the influence of social media on people's life satisfaction through two competing explanatory mechanisms
Venue: Aslib J. Inf. Manag.

The purpose of this paper is to explore how social media usage affects people's life satisfaction through two competing explanatory mechanisms.  An online survey was conducted to collect data. And the partial least squares method was used to examine the relationships among the usage of social media, social benefit, social overload and life satisfaction.  The results indicate that usage of social media can make people achieve social benefit, thus leading to enhanced life satisfaction. Unexpectedly, though usage of social media can bring the negative consequences (e.g. social overload) social overload cannot predict a decreased life satisfaction.  Concentrating on the outcomes of social aspects by using social media, this study proposes the double sided role of social media instead of single effect.
The Costs and Benefits of Active Coping for Adolescents Residing in Urban Poverty
Venue: Journal of youth and adolescence

The present study addresses the lack of specificity and diversity highlighted in recent stress literature reviews by examining active coping in relationships between exposure to violence and internalizing and externalizing symptoms in a sample of urban youth from predominantly low income, African American and Latino backgrounds. Two hundred and forty one youth (mean age at Time 1 13 years; 66 female; 41 African American, 28 Latino, 14 European American, 6 Asian American, 7 mixed/biracial, 1 American Indian/native American, .5 Hawaiian/Pacific Islander, 2 other) and their parents participated in this three wave study. Hierarchical regression analyses tested for moderation, and a cross lag panel path analysis tested for mediation. The results provide greater support for active coping as a variable that changes the relationship between exposure to community violence and externalizing symptoms, or moderation, rather than one that explains or mediates it. Further, specificity did not emerge for type of psychological outcome but did emerge for gender, such that active coping exacerbated the association between exposure to community violence and both internalizing and externalizing symptoms for girls, but not boys. These findings highlight the importance of contextual and demographic factors in influencing stress and coping processes during adolescence.
Biomechanical and biochemical outcomes of porcine temporomandibular joint disc deformation.
Venue: Archives of oral biology

The structure function relationship in the healthy temporomandibular joint (TMJ) disc has been well established, however the changes in dysfunctional joints has yet to be systematically evaluated. Due to the poor understanding of the etiology of temporomandibular disorders (TMDs) this study evaluated naturally occurring degenerative remodeling in aged female porcine temporomandibular joint (TMJ) discs in order to gain insight into the progression and effects on possible treatment strategies of TMDs.  Surface and regional biomechanical and biochemical properties of discal tissues were determined in grossly deformed =Wilkes Stage 3) and morphologically normal =Wilkes Stage 2) TMJ discs.  Compared to normal disc structure the deformed discs lacked a smooth biconcave shape and characteristic ECM organization. Reduction in tensile biomechanical integrity and increased compressive stiffness and cellularity was found in deformed discs. Regionally, the posterior and intermediate zones of the disc were most frequently affected along with the inferior surface.  The frequency of degeneration observed on the inferior surface of the disc (predominantly posterior) suggests that a disruption in the disc condyle relationship likely contributes to the progression of joint dysfunction more than the temporodiscal relationship. As such, the inferior joint space may be an important consideration in early clinical diagnosis and treatment of TMDs, as it is overlooked in techniques performed in the upper joint space, including arthroscopy and arthrocentesis. Furthermore, permanent damage to the disc mechanical properties would limit the ability to successfully reposition deformed discs, highlighting the importance of emerging therapies such as tissue engineering.
The Relationship of Teacher's Behavior and Performance with Intrinsic Motivation of the Primary School Students of Bandar Abbas City

This study examines the relationship of teacher's performance and teacher's behavior with intrinsic motivation the primary school students of Bandar Abbas city. The interaction and communication between teacher and student is an important part of the instruction and learning process. Teacher's behavior and performance should be impressive enough to encourage enthusiasm in students for learning. Without such qualities, there will be no (real) knowledge transfer. In the meantime, there is a major concern among most teachers and principals for student motivation. To make successful and effective learning happen, teachers need interested, motivated, and hardworking students. The relevant data on the research theoretical and empirical background which was used for identification of the research variables and formulation of the research problem and hypotheses was obtained through from the library research. The actual data was collected through a field inquiry using questionnaire. The target statistical population included all primary school teachers of Bandar Abbas city, Hormozgan province, Iran. Of this population, using Krejcie Morgan table for sample size, 194 teachers were initially selected among whom using simple random sampling the questionnaires was subsequently distributed. The results of the data analysis supported presence of a direct and statistically significant relationship between teacher's performance and behavior and student's intrinsic motivation among the understudy pupils.
