Distribution network analysis: A comparison between hosting and loading capacities

Hosting Capacity (HC) of distribution grids represents the maximum level of Distributed Generation (DG) which can be connected at each bus, taking into account technical requirements, in order to guarantee a reliable and secure operation of the system, compliant with the power quality prescriptions. Though HC is usually related to active users, nevertheless, in the perspective of distribution system operators, it is of great importance to make best use of the existing network facilities, without the need for reinforcement, also with respect to the growing energy request of passive users. In this direction, the paper proposes the use of an AC Optimal Power Flow-based mathematical model with the aim of comparing the available hosting capacity, for active users, with the loading margin, for passive users, in order to define the overall correct operation of a distribution network.
Global marine plankton functional type biomass distributions: Phaeocystis spp.

Abstract. The planktonic haptophyte Phaeocystis has been suggested to play a fundamental role in the global biogeochemical cycling of carbon and sulphur, but little is known about its global biomass distribution. We have collected global microscopy data of the genus Phaeocystis and converted abundance data to carbon biomass using species-specific carbon conversion factors. Microscopic counts of single-celled and colonial Phaeocystis were obtained both through the mining of online databases and by accepting direct submissions (both published and unpublished) from Phaeocystis specialists. We recorded abundance data from a total of 1595 depth-resolved stations sampled between 1955–2009. The quality-controlled dataset includes 5057 counts of individual Phaeocystis cells resolved to species level and information regarding life-stages from 3526 samples. 83% of stations were located in the Northern Hemisphere while 17% were located in the Southern Hemisphere. Most data were located in the latitude range of 50–70° N. While the seasonal distribution of Northern Hemisphere data was well-balanced, Southern Hemisphere data was biased towards summer months. Mean species- and form-specific cell diameters were determined from previously published studies. Cell diameters were used to calculate the cellular biovolume of Phaeocystis cells, assuming spherical geometry. Cell biomass was calculated using a carbon conversion factor for prymnesiophytes. For colonies, the number of cells per colony was derived from the colony volume. Cell numbers were then converted to carbon concentrations. An estimation of colonial mucus carbon was included a posteriori, assuming a mean colony size for each species. Carbon content per cell ranged from 9 pg C cell−1 (single-celled Phaeocystis antarctica) to 29 pg C cell−1 (colonial Phaeocystis globosa). Non-zero Phaeocystis cell biomasses (without mucus carbon) range from 2.9 × 10−5 to 5.4 × 103 μg C l−1, with a mean of 45.7 μg C l−1 and a median of 3.0 μg C l−1. The highest biomasses occur in the Southern Ocean below 70° S (up to 783.9 μg C l−1) and in the North Atlantic around 50° N (up to 5.4 × 103 μg C l−1).

Asynchronous PipeRench: architecture and performance evaluations

PipeRench is a configurable architecture that has the unique ability to virtualize an application using dynamic reconfiguration. This paper investigates the potential benefits and costs of implementing this architecture using an asynchronous methodology. Since clock distribution and gating are relatively easy in the synchronous PipeRench, we focus on the benefit due to decreased timing pessimism in an asynchronous implementation. Two architectures for fully asynchronous implementation are considered. PE-based asynchronous implementation yields approximately 80% improvement in performance per stripe. This implementation, however, requires significant increases in configuration storage and wire count. A few particular features of the architecture, such as the crossbar interconnect structure within the stripe, are primarily responsible for this growth in configuration bits and wires. These features, however, are the primary aspects of the PipeRench architecture that make it a good compilation target.
Structural relationships among mega-event experiences, emotional responses, and satisfaction: focused on the 2014 Incheon Asian Games

ABSTRACT In this study, the relationships among the experiences of visitors to the 2014 Incheon Asian Games, their emotional responses, and their satisfaction are explored by employing a theoretical background derived from Pine and Gilmore’s experience economy theory. It was found that the visitors’ satisfaction with the Incheon Asian Games was mainly affected by their emotional responses of pleasure and arousal. Furthermore, their entertainment, educational, and esthetic experiences were positive antecedents of pleasure and arousal. The results also showed that their educational and esthetic experiences positively influenced dominance, although the construct of dominance was not a significant antecedent of satisfaction.
Temporal codes and computations for sensory representation and scene analysis

This paper considers a space of possible temporal codes, surveys neurophysiological and psychological evidence for their use in nervous systems, and presents examples of neural timing networks that operate in the time-domain. Sensory qualities can be encoded temporally by means of two broad strategies: stimulus-driven temporal correlations (phase-locking) and stimulus-triggering of endogenous temporal response patterns. Evidence for stimulus-related spike timing patterns exists in nearly every sensory modality, and such information can be potentially utilized for representation of stimulus qualities, localization of sources, and perceptual grouping. Multiple strategies for temporal (time, frequency, and code-division) multiplexing of information for transmission and grouping are outlined. Using delays and multiplications (coincidences), neural timing networks perform time-domain signal processing operations to compare, extract and separate temporal patterns. Separation of synthetic double vowels by a recurrent neural timing network is used to illustrate how coherences in temporal fine structure can be exploited to build up and separate periodic signals with different fundamentals. Timing nets constitute a time-domain scene analysis strategy based on temporal pattern invariance rather than feature-based labeling, segregation and binding of channels. Further potential implications of temporal codes and computations for new kinds of neural networks are explored.

An exploration of the relationship between emotional intelligence and stress, psychological distress and coping strategies for undergraduate nursing students

Background: Undergraduate nursing students may experience high levels of stress during their study. This may lead to high attrition rates. Coping strategies used to deal with stress may not always be effective. A growing number of studies have examined the effects of emotional intelligence in handling stress. The primary aim of this study was to examine the relationship between emotional Intelligence, stress and psychological distress, and coping strategies for undergraduate nursing students. Methods: A descriptive correlational design was used in this study. A convenience sample of 377 nursing students participated. Data were collected by self-report questionnaires. The Schutte Self-Report Emotional Intelligence Test, Perceived Stress Scale, Kessler Psychological Distress Scale, Coping Strategy Inventory – Short Form, and a demographic survey were utilised to obtain data. Data were analysed using descriptive statistics. The relationship between emotional intelligence, perceived stress, psychological distress and coping strategies was analysed by univariate analysis (independent samples t-test, one-way ANOVA, Pearson’s Correlation) and multiple regression. Completion and submission of questionnaires was implied consent. Institutional ethics approval was obtained. Findings: Second and third year undergraduate nursing students (n=377) participated in this study. Most participants had average levels of emotional intelligence and were likely to be experiencing moderate to high levels of stress and some degree of psychological distress. The participants reported preference for utilisation of engagement, rather than disengagement, coping strategies. A negative correlation was found between emotional intelligence and perceived stress, while a positive correlation was found between emotional intelligence and coping strategies and psychological distress. Significant differences were identified in emotional intelligence level, perceived stress and utilisation of coping strategies based on individual characteristics. Conclusion: While the majority of participants had an average level of emotional intelligence and were more likely to use engagement coping strategies rather than disengagement coping strategies, a moderate proportion of students could have been experiencing moderate levels of stress and psychological distress which needed to be addressed. Future research may explore the development, application and evaluation of strategies to reduce stress and distress for students undertaking tertiary education in nursing. In particular, international students and migrants may require specific support to enhance their educational experience.
Effects of food web construction by evolution or immigration

We present results contrasting food webs constructed using the same model where the source of species was either evolution or immigration from a previously evolved species pool. The overall structure of the webs are remarkably similar, although we find some important differences which mainly relate to the percentage of basal and top species. Food webs assembled from evolved webs also show distinct plateaux in the number of tropic levels as the resources available to system increase, in contrast to evolved webs. By equating the resources available to basal species to area, we are able to examine the species-area curve created by each process separately. They are found to correspond to different regimes of the tri-phasic species-area curve.
Visual cube and on-line analytical processing of images

On-Line Analytical Processing (OLAP) has shown great success in many industry applications, including sales, marketing, management, financial data analysis, etc. In this paper, we propose Visual Cube and multi-dimensional OLAP of image collections, such as web images indexed in search engines (e.g., Google and Bing), product images (e.g. Amazon) and photos shared on social networks (e.g., Facebook and Flickr). It provides online responses to user requests with summarized statistics of image information and handles rich semantics related to image visual features. A clustering structure measure is proposed to help users freely navigate and explore images. Efficient algorithms are developed to construct Visual Cube. In addition, we introduce the new issue of Cell Overlapping in data cube and present efficient solutions for Visual Cube computation and OLAP operations. Extensive experiments are conducted and the results show good performance of our algorithms.
A systematical approach to expose manufacturing system as a service

Nowadays, the manufacturing industry trends for reorganization in geographically dispersed systems with manufacturing activities realized by distributed and autonomous components. Advances in mechatronics, automation, communication, and information technologies support the feasibility of these novel structures. In this sense, SOA (Service Oriented Architecture) is a way to treat the distribution of manufacturing resources considering the heterogeneous nature of this environment. Aim to guarantee the autonomy and interoperability of manufacturing system service, a systematical procedure is presented to define properly these services. These manufacturing services consider operations such as teleoperation and remote monitoring of manufacturing activities, users online request, and shared resources management. Based on the nature of this type of system it is considered discrete event system (DES), and techniques derived from Petri net (PN), including Production Flow Schema (PFS), are used in a PFS/PN modeling approach. This approach has been proven efficient for hierarchical description, analysis and control of DES. The system is approached in different levels of abstraction: a conceptual model which is developed through PFS technique and a functional model which is developed in PN. Finally, it is presented a particular implementation of the proposed procedure to define a manufacturing service, in which different and specific issues of distributed manufacturing activities are considered.
Effect of Glutathione Depletion on Ifosfamide Nephrotoxicity in Rats

Kidney injury is an important side effect of the chemotherapeutic agent ifosfamide in humans. Previous studies have shown that treatment with ifosfamide reduces kidney glutathione and that the toxicity of ifosfamide is enhanced in glutathione-depleted renal tubule cells in vitro. In this study, we examined the effect of glutathione depletion on ifosfamide nephrotoxicity in vivo using rats treated with the glutathione-depleting agent buthionine sulfoximine. Animals received 80 mg/kg ifosfamide intraperitoneally daily for three days with or without buthionine sulfoximine in drinking water. Buthionine sulfoximine produced a significant fall in renal glutathione content but did not affect kidney function. Ifosfamide-treated rats developed low-grade glucosuria, phosphaturia and proteinuria that worsened with concomitant buthionine sulfoximine therapy. These findings indicate that glutathione depletion exacerbates ifosfamide nephrotoxicity in rats and suggest that pharmacological methods for replenishing intracellular glutathione may be effective in ameliorating ifosfamide-induced renal injury.
Perception, Production, and Perception-Production: Research findings and implications for language pedagogy

When we are born our perceptual systems are capable of discriminating sounds that occur in English, Spanish, Hindi, or any other language. During the first year, our perception begins to zero in on the particular set of sounds that are contrastive in our native language(s) (L1s) (Kuhl et al., 2006). For example, a child whose parents are L1 English speakers will pick up on the fact that /b/ and /p/ are contrastive in English (e.g., “bet” vs. “pet”) and that the major difference is in the burst of air that occurs when the stop is released (i.e., there is a stronger burst of air, or more aspiration, on /p/ than /b/). A child whose parents are L1 Hindi speakers will pick up on this contrast, which also occurs in Hindi, as well as other contrasts that occur in Hindi but not in English. As our perception becomes attuned to our L1(s), we become more sensitive to L1 contrasts, such as /b/ vs. /p/ for L1 English speakers, and less sensitive to non-native contrasts, even though our ability to discriminate non-native sounds remains intact. When we begin to learn another language (L2) later in life, be it through formal instruction at university or through immersion if we move to another country where a different language is spoken, our L1 acts as a filter, altering our perception of L2 sounds. Consequently, we may not detect differences between contrastive L2 sounds that are not contrastive in our L1, and we may fail to notice the difference between our accented pronunciation of the L2 and the target pronunciation.

Activation and Habituation in Olfaction—An fMRI Study

This study investigated human BOLD responses in primary and higher order olfactory cortices following presentation of short- and long-duration odorant stimuli using a 3-T MR scanner. The goal was to identify temporal differences in the course of the response that might underlie habituation. A short-duration stimulus (9 s) consistently activated the primary olfactory cortex (POC). After a long stimulus (60 s), the temporal form of the response differed in different parts of the olfactory network: (1) The POC (piriform, entorhinal cortex, amygdala) and, interestingly, the hippocampus and, to a certain degree, the anterior insula show a short, phasic increase in the signal, followed by a prolonged decrease below baseline. (2) In the orbitofrontal cortex a sustained increase in activation was seen. This increase lasted approximately as long as the duration of odorant presentation ( approximately 60 s). (3) The mediodorsal nucleus of the thalamus and the caudate nucleus responded with an increase in signal which returned to baseline after approximately 15 to 30 s. The correlated biphasic hemodynamic response in the POC, hippocampus, and anterior insula during prolonged olfactory stimulation suggests that these three areas may interact closely with each other in the control of habituation. These results extend recent data which showed habituation of the rat piriform cortex and dissociation between the POC and the orbitofrontal cortex.
Computer Science Education for Primary and Lower Secondary School Students

We explore the feasibility of early introduction to automata theory through gamification. We designed a puzzle game that players can answer correctly if they understand the fundamental concepts of automata theory. In our investigation, 90 children played the game, and their actions were recorded in play logs. An analysis of the play logs shows that approximately 60% of the children achieved correct-answer rates of at least 70%, which suggests that primary and lower secondary school students can understand the fundamental concepts of automata theory. Meanwhile, our analysis shows that most of them do not fully understand automata theory, but some of them have a good understanding of the concept.
Caching P2P Traffic: What Are the Benefits for an ISP?

Caching P2P content could be an effective way of alleviating network usage, thereby reducing operation costs for operators. However, cache performances are affected by a lot of factors related to the cache itself, but also to the properties of the P2P overlay, the P2P contents, and the cache deployment location. In order to evaluate the potential usefulness of P2P caches, we have setup a large-scale experiment for monitoring traffic of a popular P2P application in the operational network of France Telecom. After gaining some insights on the characteristics of the P2P traffic, we simulate a cache based on data contained in our trace. We are then able to evaluate cache performances in terms of the bandwidth that could have been saved if a cache was really in the network during our measurements. Additionally, the paper studies the impact of various factors on performance, such as cache properties and more importantly the number of customers served by the cache. The results show that the bandwidth gain can reach 23% of P2P traffic with a passive cache.
Pushdown flow analysis of first-class control

Pushdown models are better than control-flow graphs for higher-order flow analysis. They faithfully model the call/return structure of a program, which results in fewer spurious flows and increased precision. However, pushdown models require that calls and returns in the analyzed program nest properly. As a result, they cannot be used to analyze language constructs that break call/return nesting such as generators, coroutines, call/cc, etc. In this paper, we extend the CFA2 flow analysis to create the first pushdown flow analysis for languages with first-class control. We modify the abstract semantics of CFA2 to allow continuations to escape to, and be restored from, the heap. We then present a summarization algorithm that handles escaping continuations via a new kind of summary edge. We prove that the algorithm is sound with respect to the abstract semantics.
