Voltage quality enhancement using unified power quality conditioner (UPQC)

Recently power quality has become more important issue. Day by day in industries and in distribution area power electronics based device are widely used and creates more power quality problems. The quality of the power is defective by certain reasons. This improvement of the quality of the power is seen e.g. as sag, swell, over voltages, under voltage, and harmonics. The quality of the power may be improved by using power conditioning equipment, which may be active filter. This is one of the most modern power conditioning devices, i.e. the unified power quality conditioner (UPQC), which consists of the parallel active power filter (PAPF) and the series active power filter (SAPF). The UPQC is a power conditioning device able to compensate all kinds of power quality faults. UPQC is also used to filter both current and voltage harmonics and to compensate the voltage sag. This work deals with a way to improve the voltage compensation performance of the series APF. This improvement is achieved by improving the conventional hysteresis control system.
The Multiple Contexts of Food Insecurity : Evaluating the Impact on Child Energy Balance

This study uses data from the Early Childhood Longitudinal Survey, Kindergarten Class of 1998 to explore the impact of food insecurity, school environment and food infrastructure on elementary school-aged children’s body weight, food purchasing decisions and physical activity choices. Results show that Federal support for nutrition in the form of expenditures, a lower county unemployment rate, higher average wages, and access to unemployment compensation are associated with a lower risk of being food insecure. Using longitudinal methods, the study finds a positive association between household food insecurity and child BMI, but the connection is not consistent across gender and racial groups. This study was conducted by the University of Utah, under a cooperative research agreement with USDA’s Economic Research Service (ERS) Food Assistance and Nutrition Research Program (FANRP): agreement number 58-5000-6-0110 (ERS project representative: Jessica Todd). The views expressed are those of the authors and not necessarily those of ERS or USDA.
Problem-Solving by Immersive Virtual Reality: Towards a More Efficient Product Emergence Process in Automotive

The Automotive Industry has been actively investigating how Virtual Reality (VR) hardware and software platforms could provide new enhanced design tools since the end of the nineties, when DaimslerChrysler AG produced DBView, one the first software platforms for immersive visualisation and manufacturing simulations used in Automotive, featuring higher interaction with virtual objects through physics simulation. Since then, VR technologies have evolved further. Today interactive 3D immersive environments can be used to provide more efficient ways to solve problems and improve design choices at very early stages of new product developments. This paper analyses how Automotive (and Manufacturing in general) can benefit from the adoption of VR tools when they are examined from a problem-solving perspective in the context of the Product Emergence Process (PEP). Two areas of product development have been considered for this purpose: Quality Assessment and Process Planning. Related demonstration scenarios have been developed at the Virtual Engineering Centre of the University of Liverpool with the purpose of carrying out an exhaustive evaluation of benefits gained by the adoption of VR technologies in new product developments
PVFlow: Flow-Table Virtualization in POF-based vSDN Hypervisor (PVX)

It is known that by combining network virtualization with software-defined network (SDN), people can realize virtual SDNs (vSDNs) for enhanced programmability, adaptivity and cost-effectiveness. Meanwhile, protocol-oblivious forwarding (POF) can overcome the protocol-dependent restriction of Open-Flow and provide a more generic abstraction model of the forwarding elements in SDNs to realize a protocol-independent data plane. In this work, we design a flow-table virtualization module, i.e., PVFlow, to realize resource-efficient flow-table virtualization for POF-based vSDNs. To fully explore the flexibility of POF and support arbitrary matching fields in vSDNs’ flow-tables, we propose the idea of “BigMatch”, which enables different flow-tables in vSDNs to share a matching stage in a substrate POF switch efficiently. We implement PVFlow in a POF-based network virtualization hypervisor (NVH) system, i.e., PVX, and verify its effectiveness on improving the efficiency of flow-table virtualization with experiments.
Scribble legalization cryptographic aspect based on data access control for steam count

Recently, healthcare applications adopt the advents of cloud technologies. Electronic Health Records (EHR) plays a vital role in healthcare environments. Thus, the proper usage and protection of EHR systems enabled the growth of cloud based healthcare applications which implies the patients-safety of their sensitive information. However, the data owner should be online in order to send the PRE keys to the CSP in a timely fashion, to prevent the revoked user from accessing the future data. The delay of issuing the PRE keys may cause potential.
Is Black Carbon an Unimportant Ice‐Nucleating Particle in Mixed‐Phase Clouds?

It has been hypothesized that black carbon (BC) influences mixed‐phase clouds by acting as an ice‐nucleating particle (INP). However, the literature data for ice nucleation by BC immersed in supercooled water are extremely varied, with some studies reporting that BC is very effective at nucleating ice, whereas others report no ice‐nucleating ability. Here we present new experimental results for immersion mode ice nucleation by BC from two contrasting fuels (n‐decane and eugenol). We observe no significant heterogeneous nucleation by either sample. Using a global aerosol model, we quantify the maximum relative importance of BC for ice nucleation when compared with K‐feldspar and marine organic aerosol acting as INP. Based on the upper limit from our laboratory data, we show that BC contributes at least several orders of magnitude less INP than feldspar and marine organic aerosol. Representations of its atmospheric ice‐nucleating ability based on older laboratory data produce unrealistic results when compared against ambient observations of INP. Since BC is a complex material, it cannot be unambiguously ruled out as an important INP species in all locations at all times. Therefore, we use our model to estimate a range of values for the density of active sites that BC particles must have to be relevant for ice nucleation in the atmosphere. The estimated values will guide future work on BC, defining the required sensitivity of future experimental studies.
The Water Footprints of Morocco and the Netherlands

Although bulk water itself is not a tradable commodity, agricultural commodities – that generally consume a lot of water during production – are increasingly being traded. As a result, water use within a nation is no longer an appropriate indicator of national water demand, at least not if one takes the consumer’s perspective. The aim of the paper is to assess the water footprints of Morocco, a semi-arid / arid country, and the Netherlands, a humid country. The water footprint of a country is defined as the volume of water needed for the production of the goods and services consumed by the inhabitants of the country. The internal water footprint is the volume of water used from domestic water resources; the external water footprint is the volume of water used in other countries to produce goods and services imported and consumed by the inhabitants of the country. The study shows that both Morocco and the Netherlands import more water in virtual form (in the form of water-intensive agricultural commodities) than they export, which makes them dependent on water resources elsewhere in the world. The water footprint calculations show that Morocco depends for 14% on water resources outside its own borders, while the Netherlands depend on foreign water resources for 95%. It is shown that international trade can result in global water saving when a water-intensive commodity is traded from an area where it is produced with high water productivity to an area with lower water productivity. If Morocco had to domestically produce the products that are now imported from the Netherlands, it would require 780 million m3/yr. However, the imported products from the Netherlands were actually produced with only 140 million m3/yr, which implies a global water saving of 640 million m3/yr.

An efficient object recognition based on Gabor transform and LBP variance

Recognizing objects from arbitrary aspects is always a highly challenging problem in applied engineering and computer vision fields. At present, most existing algorithms mainly focus on specific viewpoint detection. Hence, in this paper we propose a novel recognizing model, which combines Gabor transform with LBP variance to handle the problem of different viewpoints and pose changing. Then, the images of inaccurate recognizing are evaluated by learning and fed back the detector to avoid the same mistakes in the future. The principal idea is to extract intrinsic viewpoint invariant features from the unseen poses of object, and then to take advantage of these features to support recognition. Compared with other recognition models, the proposed approach can efficiently tackle the multi-view problem and promote the recognition performance. For a quantitative evaluation, this novel algorithm has been tested on two benchmark datasets such as Caltech 101 and PASCAL VOC 2011datasets. The experimental results validate that our approach can recognize objects more precisely and outperforms others single view recognition methods.
Using Sprint Velocity Decrement to Enhance Acute Sprint Performance.

Cochrane, DJ and Monaghan, D. Using sprint velocity decrement to enhance acute sprint performance. J Strength Cond Res XX(X): 000-000, 2018-Acute sled towing has the capability to elicit a potentiation. Currently, sled loading is determined from body mass (BM) percent. However, it may be more relevant to use a percentage of maximal sprint reduction to determine an individual's load. The purpose of this study was to determine if individualizing sled loads at 35 and 55% reduction in velocity would improve 20-m sprint performance. In addition, electromyography (EMG) was assessed to determine if any sprint-related improvements in velocity were due to changes in neural excitation. Twelve senior club male rugby union players performed familiarization and 2 sled towing sessions using a randomized, cross-over, and counterbalanced design. Testing sessions involved: baseline unresisted 20-m sprints, resisted sprint (35 and 55% reduction in velocity), and unresisted 20-m sprints at 2, 4, 6, 8, 12, and 16 minutes. The sled load to reduce maximal velocity by 35% significantly improved 20-m velocity (p <0.05, effect size [ES] = 0.21) compared with the heavier sled load (55% reduction in maximum velocity). A significant decline in sprint velocity occurred at 12 minutes (p < 0.01, ES = -0.61) and 16 minutes (p < 0.01, ES = -0.45) compared with baseline velocity. Other time intervals reported trivial small nonsignificant changes in sprint velocity (p >0.05). There was no significant change in EMG. Reducing sprint velocity provides an alternate method to determining sprint loading. Nonetheless, a greater range of reduced sprint velocity is required to assess if it is more effective than using BM percent procedure.
Mucogingival conditions in the natural dentition: Narrative review, case definitions, and diagnostic considerations

BACKGROUND Mucogingival deformities, and gingival recession in particular, are a group of conditions that affect a large number of patients. Since life expectancy is rising and people are retaining more teeth both gingival recession and the related damages to the root surface are likely to become more frequent. It is therefore important to define anatomic/morphologic characteristics of mucogingival lesions and other predisposing conditions or treatments that are likely to be associated with occurrence of gingival recession. OBJECTIVES Mucogingival defects including gingival recession occur frequently in adults, have a tendency to increase with age, and occur in populations with both high and low standards of oral hygiene. The root surface exposure is frequently associated with impaired esthetics, dentinal hypersensitivity and carious and non-carious cervical lesions. The objectives of this review are as follows (1) to propose a clinically oriented classification of the main mucogingival conditions, recession in particular; (2) to define the impact of these conditions in the areas of esthetics, dentin hypersensitivity and root surface alterations at the cervical area; and (3) to discuss the impact of the clinical signs and symptoms associated with the development of gingival recessions on future periodontal health status. RESULTS An extensive literature search revealed the following findings: 1) periodontal health can be maintained in most patients with optimal home care; 2) thin periodontal biotypes are at greater risk for developing gingival recession; 3) inadequate oral hygiene, orthodontic treatment, and cervical restorations might increase the risk for the development of gingival recession; 4) in the absence of pathosis, monitoring specific sites seems to be the proper approach; 5) surgical intervention, either to change the biotype and/or to cover roots, might be indicated when the risk for the development or progression of pathosis and associated root damages is increased and to satisfy the esthetic requirements of the patients. CONCLUSIONS The clinical impact and the prevalence of conditions like root surface lesions, hypersensitivity, and patient esthetic concern associated with gingival recessions indicate the need to modify the 1999 classification. The new classification includes additional information, such as recession severity, dimension of the gingiva (gingival biotype), presence/absence of caries and non-carious cervical lesions, esthetic concern of the patient, and presence/absence of dentin hypersensitivity.
Inappropriate sinus tachycardia

Inappropriate sinus tachycardia (IST) is a clinical syndrome, oftentimes debilitating, defined by fast sinus rates (>100 b.p.m. at rest or >90 b.p.m. on average over 24 h and not due to underlying causes) associated with symptoms that may include palpitations, as described in some guidelines and consensus documents. While heart rates may vary by patient, especially based upon gender and age, some individuals experience sinus tachycardia or persistent fast sinus rates with no symptoms; these individuals would not necessarily be considered to have the syndrome of IST. Various explanations for IST have been considered but a definitive common mechanism is not yet known; the true aetiology may be multifactorial. A thorough evaluation of secondary causes of tachycardia is required in the work-up of all cases and if found, must be treated before a diagnosis of IST can be made. Finally, effective treatments vary but can include ivabradine, beta-blockers, or calcium channel antagonists; ablation is seldom advised.
Skeletal Muscle Metabolism in Duchenne and Becker Muscular Dystrophy—Implications for Therapies

The interactions between nutrition and metabolism and skeletal muscle have long been known. Muscle is the major metabolic organ—it consumes more calories than other organs—and therefore, there is a clear need to discuss these interactions and provide some direction for future research areas regarding muscle pathologies. In addition, new experiments and manuscripts continually reveal additional highly intricate, reciprocal interactions between metabolism and muscle. These reciprocal interactions include exercise, age, sex, diet, and pathologies including atrophy, hypoxia, obesity, diabetes, and muscle myopathies. Central to this review are the metabolic changes that occur in the skeletal muscle cells of muscular dystrophy patients and mouse models. Many of these metabolic changes are pathogenic (inappropriate body mass changes, mitochondrial dysfunction, reduced adenosine triphosphate (ATP) levels, and increased Ca2+) and others are compensatory (increased phosphorylated AMP activated protein kinase (pAMPK), increased slow fiber numbers, and increased utrophin). Therefore, reversing or enhancing these changes with therapies will aid the patients. The multiple therapeutic targets to reverse or enhance the metabolic pathways will be discussed. Among the therapeutic targets are increasing pAMPK, utrophin, mitochondrial number and slow fiber characteristics, and inhibiting reactive oxygen species. Because new data reveals many additional intricate levels of interactions, new questions are rapidly arising. How does muscular dystrophy alter metabolism, and are the changes compensatory or pathogenic? How does metabolism affect muscular dystrophy? Of course, the most profound question is whether clinicians can therapeutically target nutrition and metabolism for muscular dystrophy patient benefit? Obtaining the answers to these questions will greatly aid patients with muscular dystrophy.
Association analysis of interleukin‐18 gene promoter region polymorphisms and susceptibility to sporadic breast cancer in Chinese Han women

Interleukin‐18‐137G/C, ‐607G/T polymorphisms play multiple roles in various cancers. However, studies focused on its involvement in breast cancer remain controversial, and no study has taken the interaction between interleukin‐18 (IL‐18) gene polymorphism and body mass index (BMI), menopause into consideration. The study investigated the association between IL‐18‐137, ‐607 polymorphisms and risk of breast cancer and a possible interaction between the 2 single nucleotide polymorphisms (SNPs) and BMI, menopause in Chinese Han woman.
Biological corridors and connectivity

The ability of individual animals to move across complex landscapes is critical for maintaining regional populations in the short term (Fahrig 2003; Cushman 2006), and for species to shift their geographic range in response to climate change (Heller & Zavaleta 2009). As organisms move through spatially complex landscapes, they respond to multiple biotic and abiotic factors to maximize access to resources and mates while minimizing fitness costs such as mortality risks. Habitat fragmentation decreases dispersal success (Gibbs 1998), increases mortality (Fahrig et al. 1995) and reduces genetic diversity (Reh & Seitz 1990; Wilson & Provan 2003). Local populations may decline if immigration is prevented (Brown & Kodric-Brown 1977; Harrison 1991) and may prevent recolonization following local extinction (Semlitsch & Bodie 1998). The goal of this chapter is to describe the state of the art in quantitative corridor and connectivity modelling. We will review several critical issues in modelling, and provide expert guidance and examples to help practitioners implement effective programmes to preserve, enhance or create connectivity among wildlife populations. We first
JORDAN: A Novel Traffic Engineering Algorithm for Dynamic Adaptive Streaming over HTTP

Video streaming accounts for most of the Internet traffic. To cope with the increasing traffic and achieve better service, Internet service providers (ISPs) and applications take actions to mitigate the problem independently. Namely, ISPs perform traffic engineering (TE) to ensure the whole network capacity is evenly utilized based on an estimated traffic matrix. Additionally, many applications employ rate adaption mechanisms (such as Dynamic Adaptive Streaming over HTTP, DASH) to adjust streaming bit rates according to the measured network conditions. However, deploying these two interrelated methods separately may lead to suboptimal performance. To solve this problem, we first illustrate the challenges. Then we formulate a problem for Jointly Optimizing Routing and Dynamic Adaptation in Network (JORDAN) and propose an algorithm to obtain a near-optimal solution. Finally, our simulation results show that JORDAN can achieve up to 180% improvement in terms of average bit rates than TE and DASH working separately.
Preterm Birth : Causes , Consequences , and Prevention

Although individual behaviors have not been proven to have a strong influence on the risk of preterm birth, consistent evidence suggests that a constellation of favorable lifestyle factors are associated with more favorable pregnancy outcomes. These include a reduced risk of preterm birth among women who engage in leisure time physical activity, women who do not use cocaine, and those who have a favorable diet. There is clear evidence that a favorable lifestyle and a greater degree of health consciousness are associated with a reduced risk of preterm birth above and beyond what can be measured effectively and controlled in observational studies. Despite the lack of success in pinpointing behaviors that affect the occurrence of preterm birth, continued efforts are needed to better understand and ultimately pinpoint the aspects of a favorable lifestyle that are associated with a reduced risk of preterm birth. The results of research on psychosocial factors and preterm birth have accumulated rapidly in recent years. What is most clear from this large body of evidence is that psychosocial factors should not be grouped together as if they were one risk factor. Rather, they must be studied as the distinct theoretical risk factors that they are. Evidence indicates that some psychosocial factors in the etiology of preterm birth include major life events, chronic and catastrophic stress, maternal anxiety, personal racism, and lack of support.
