Estratetegia de Control Droop con Reducido Número de Sensores Para Inversores en Paralelo en UPS

A droop control strategy is proposed to achieve parallel operation of single-phase inverters for double conversion UPS applications. The distinctive caracteristics of this control strategy are a reduced number of sensors to achieve output impedance adjustment, fixed frequency of the output voltage, reduced circulating current between the inverters, excelent output voltage regulation and compliance with specifications given by international standards for transient and stationary response. A simple design methodology is proposed to choose the droop controller gain and adjust the output impedance value of each inverter, validating the proposal with simulation results. Resumen —Se propone una estrategia de control droop para la conexión de inversores monofásicos en paralelo utilizados en UPS de doble conversión. Esta estrategia logra una reducida cantidad de sensores para el ajuste de la impedancia de salida, operación con frecuencia fija de la tensión de salida, reducida corriente de circulación, excelente regulación, y cumple con las especificaciones de desempeño transitorio y de régimen permanente establecidas por normas internacionales. Se propone una metodología simple para la selección de la ganancia del controlador droop y el ajuste del valor de la impedancia de salida para cada inversor, validando la propuesta con resultados de simulación.
Homography based visual odometry with known vertical direction and weak Manhattan world assumption

—In this paper we present a novel visual odometry pipeline, that exploits the weak Manhattan world assumption and known vertical direction. A novel 2pt and 2.5pt method for computing the essential matrix under the Manhattan world assumption and known vertical direction is presented that improves the efﬁciency of relative motion estimation in the visual odometry pipeline. Similarly an efﬁcient 2pt algorithm for absolute camera pose estimation from 3D-2D correspondences is presented that speeds up the visual odometry pipeline as well. We show that the weak Manhattan world assumption and known vertical allow for direct relative scale estimation, without recovering the 3D structure. We evaluate our algorithms on synthetic data and show their application on real data sets from camera phones and robotic micro aerial vehicles. Our experiments show that the weak Manhattan world assumption holds for many real-world scenarios.
PASSIVE METAMATERIALS STRUCTURES USING IN MICROWAVE NONDESTRUCTIVE TESTING

Metamaterials are special one-, twoor three-dimensional artificial structures with electromagnetic properties generally not found in the nature. Due to the simultaneous negative values of permittivity (ɛ) and permeability (μ), the wave vector and the vectors of electricand magnetic-field intensity form a left-handed triplet with the result of antiparallel phase and group velocity and back wave propagation [1]. These unique properties of the left-handed materials have allowed novel applications and devices to be developed [2]. This paper is devoted to the application of metamaterials to the design of microwave sensor for dielectric properties of any solid sample detection. The sensor was projected based on the metamaterial structure consisting of the split ring resonators (SRR) etched on the appropriate dielectric substrate. The most interesting application of SRR is due to its resonant nature and strong response on applied electromagnetic field [3]. Using this characteristic the dielectric properties of unknown sample can be detected. When the dielectric sample occurs in the vicinity of the sensitive area of SRR, the electromagnetic field in this area is disturbed. According to this modification the dielectric properties of the sample can be characterized.
VERTICAL AND HORIZONTAL FABRICATION OF ALGINATE-BASED VASCULAR-LIKE CONSTRUCTS USING INKJETTING

Organ printing, among different tissue engineering innovations, is a layer-by-layer additive fabrication approach for making three-dimensional (3D) tissue and organ constructs using cellular spheroids or bioink as building blocks. The capability to fabricate 3D cellular tubes is the first step as well as an important indicator of the overall feasibility of envisioned organ printing technology. In this study, vascular-like alginate tubes with a hemi-branching point, which mimic typical vascular constructs, are fabricated both vertically and horizontally using drop-on-demand inkjetting. In addition, manufacturing challenges associated with the vertical and horizontal printing configurations are briefly discussed. This study lays a foundation for the effective and efficient fabrication of viable 3D vascular constructs with complex anatomies (e.g. branching) as required in organ printing of vascular trees.
CS Recovery Algorithm y Compressive Measurements e Edges FDs Fourier Descriptors

Fourier descriptors (FDs) are shape-based features for the recognition of two-dimensional connected shapes. We propose a method that can extract FDs of an object directly from compressive measurements without reconstructing the image. Our method entails estimating the edges via discrete horizontal and vertical image gradients from compressive measurements. Fourier descriptors are then extracted from the thresholded edges. One of the main advantages of the proposed method is that it requires fewer number of compressive measurements to estimate FDs than required to estimate the original image. Various numerical experiments on synthetic and real data demonstrate the effectiveness of the proposed method.
Detecting a metastable olivine wedge in the subducting Pacific slab under Japan Sea Summary :

【Introduction of Research】 1. Detecting a metastable olivine wedge in the subducting Pacific slab under Japan Sea Summary: We apply a forward-modeling approach to high-quality arrival time data from 23 deep earthquakes greater than 400 km depth to investigate the detailed structure of the subducting Pacific slab beneath the Japan Sea. Our results show that a finger-like anomaly exists within the subducting Pacific slab below 400 km depth, which has a P-wave velocity 5% lower than the surrounding slab velocity (or 3% lower than that of the normal mantle), suggesting the existence of a metastable olivine wedge (MOW) in the slab. The MOW top and bottom depths are 400 and 560 km, respectively. Most of the deep earthquakes are located in the MOW. Our results favor transformational faulting as the mechanism for deep earthquakes.
Paradigm Integration between Equilibrium and Non-equilibrium Concepts for Evaluating Vegetation Dynamics in Rangeland Ecosystems

There are two major paradigms involved in applied ecological research on rangeland ecosystems: the equilibrium paradigm and non-equilibrium paradigm. The former idea posits that communities will respond in a sequential and predictable manner to the environment and disturbances such as grazing. The latter idea has minimized ecosystem regulation and stability and placed greater emphasis on external factors such as climatic variability and episodic events, implying that ecosystems are less predictable than indicated by the equilibrium concept. Previous literature has suggested that both equilibrium and non-equilibrium paradigms must be incorporated into rangeland management perspectives if the solid science of rangeland ecology is to continue to underpin them. However, the current state-of-the-art in rangeland management appears to be progressing at the extremes of the equilibrium–non-equilibrium continuum. Consequently, there is uncertainty as to whether the current knowledge is the key to successful environmental management of rangeland ecosystems. Here, I have synthesized the extensive debates on rangeland ecology from a rangeland management perspective, and merged the two major paradigms by placing the idea of ecological thresholds at the core of the study framework. The clear implication is that both equilibrium and non-equilibrium paradigms must be incorporated into vegetation management in rangeland ecosystems. Effective vegetation management based on both paradigms can prevent adverse changes in states before ecological thresholds are reached, while maintaining or enhancing the ecological resilience of rangeland ecosystems.

ASCORBIC ACID AMELIORATES GENOTOXIC EFFECTS OF COBALT NANOPARTICLES AND COBALT CHLORIDE IN IN VIVO DROSOPHILA ASSAYS

Nanoparticles are used in a wide variety of fields due to their many advantages in different industries, but knowledge about the genotoxic potential of nanoparticles is rather limited. It is known that genetic changes such as mutation, recombination, and DNA damage that occur in organisms are related to many diseases. Therefore, it is very important to determine such effects of nanomaterials. Ascorbic acid (AA), one of the water-soluble antioxidant micronutrients, can be found in many vegetables and fruits and acts as a cancer preventive agent by protecting cells against oxidative damage. In this study, the genotoxic effects of cobalt nanoparticles (CoNP, 40nm) and cobalt chloride (CoCl2) and the antigenotoxic effect of AA against them were examined by means of both the Somatic Mutation and Combination Test (SMART) and the Single Cell Gel Electrophoresis Test (COMET) on Drosophila melanogaster. The SMART method is a fast, reliable, and economical in vivo test method based on the loss of heterozygosity genetic changes (point mutation, deletion, non-separation, and recombination) occurring in the wing imaginal disc cells. The alkaline COMET assay is a sensitive and fast technique for the detection of single-strand DNA breaks. In this study, both preliminary and concurrent applications were performed in the SMART method. It is seen that the damage induced by CoCl2 and CoNPs in the pretreated group is higher than in the simultaneous application. On the other hand, simultaneous applications were made in the COMET study, and it was observed that AA decreased the genotoxicity with statistical significance.
standardized ethogram for the felidae : A tool for behavioral esearchers auren

Standardized ethograms offer many practical benefits to behavioral researchers, and several examples exist today for various species and taxa. Despite historic evidence that suggests the family Felidae share similar behavioral repertoires, no standardized ethogram providing comprehensive behavioral definitions exists. In order to create a working ethogram for the Felidae, we conducted a thorough literature review of published articles and books containing behavioral definitions designed for felid species. A total of 95 documents qualified for inclusion, and each was evaluated to identify the terminology used in its behavioral definitions, along with any categorization implemented. The articles included the behaviors of 30 species and 40 subspecies of felids, with the most frequent single study species being the domestic cat (Felis catus), followed by several “big cats”. The results were organized into the following mutually exclusive groups for comparison: domestic cat studies, big cat studies, and small cat studies excluding domestic cats (i.e. small exotic cats). Systematic review of definitions confirmed that researchers tend to define felid behavior in similar manners, although some divergence was found between the inclusion of behaviors in domestic and exotic (non-domestic) cat studies. Information from the literature review was used to create a standardized, universal ethogram for use in future felid behavioral studies. The final ethogram suggests the use of “base behaviors” which can be altered using pre-defined modifiers in order to accommodate the requirements of individual studies while retaining consistent terminology. Common behavioral categories are also defined, and suggestions of behaviors that qualify within each category are presented to further assist researchers when developing their study. The ethogram was designed to be user-friendly with clear definitions for each behavior, which should be coherent to a diverse range of observers. We anticipate that use of this ethogram will save researchers time and effort in creating behavioral definitions for their study, while also assisting in unifying felid behavioral research. © 2015 Elsevier B.V.

Greeneria uvicola , cause of bitter rot of grapes , belongs in the Diaporthales

Farr, D. E, L. A. Castlebury, A. Y. Rossman, & O. Erincik. (2001). Greeneria uvicola, cause of bitter rot of grapes, belongs in the Diaporthales. Sydowia 53 (2): 185-199. Bitter rot of grapes, a cosmopolitan disease, is caused by Greeneria uvicola, an asexually reproducing fungus with no known sexual state. Based on molecular sequence data, specifically the large subunit of the nuclear ribosomal DNA, it was determined that G. uvicola is a member of the Diaporthales. Greeneria uvicola is re-described and illustrated based on two recent collections and comparison with an authentic specimen. Data are also presented that suggest the family Magnaporthaceae, including Magnaporthe grisea (anamorph: Pyricularia grisea) and Gaeumannomyces graminis (anamorph: Harpophora sp.), plant pathogens of wheat, rice, and other grass crops, should be excluded from the Diaporthales.
Morphology and Biogeography phylogenetic investigation of the Neotropical genus Alphamenes van er Vecht , 1977 ( Hymenoptera , Vespidae , Eumeninae ) etícia

Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systematics have been proposed in the last five years, including the genus Alphamenes. This taxon contains seven described species whose distribution is exclusively Neotropical. Females are morphologically homogeneous, and characters related to copulatory organs are useful in male diagnosis. This contribution forms the first phylogenetic approach to include all species of Alphamenes, hence the first to strongly test for group monophyly. Our cladistic results recovered Alphamenes as a monophyletic group supported by male genital features. Relationships among included species also rely ystematics axonomy upon genitalic characters, highlighting the importance of these attributes for eumenine systematics. Recent phylogenetic investigations applied to the Neotropical fauna of potter wasps represent desirable advancements towards a natural classification for the group. © 2018 Published by Elsevier Editora Ltda. on behalf of Sociedade Brasileira de Entomologia.

P 2 B . 7 TRUNCATION ERRORS IN HISTORICAL WSR-88 D RAINFALL PRODUCTS

The National Weather Service (NWS) WSR-88D radars host a number of complex scientific algorithms that produce value-added radar products for our customers, including precipitation products of various durations in digital and graphical formats from the Precipitation Processing System (PPS; Fulton et al. 1998). Recent detailed analyses of these rainfall products have uncovered a small and very subtle software error, which we will call the “truncation error,” that has been latent in the radar software since the radars were first deployed over 10 years ago. The impact of the truncation error on the rainfall products generated in legacy Radar Product Generator (RPG) Software Builds 10 and prior has been non-trivial in certain circumstances, particularly stratiform rainfall events, and may largely explain the long-known tendency for the PPS to underestimate rainfall in these situations.
Title Ideal Secret Sharing Schemes with Share Selectability

In this paper, we investigate a new concept, called share selectable secret sharing, where no unauthorized set can obtain information of the secret (in the information-theoretic sense) even if shares are selectable as arbitrary values which are independent of the secret. We propose two totally selectable (i.e., all users’ shares are selectable) secret sharing schemes with unanimous structure. We also propose a quasiselectable (i.e., a part of each user’s share is selectable) secret sharing scheme with certain hierarchical structures which contains special cases of the hierarchical threshold structures introduced by Tamir Tassa in TCC2004 (or its full version (J. Cryptology2007)). If all selectable shares are randomly chosen, then our schemes are perfect. Finally, we discuss the effect of the leakage information of the secret if a weak secret is indicated as a selectable share.
Haemodynamic and respiratory response to the paravertebral injection of 0 . 5 % ropivacaine and 0 . 5 % bupivacaine

Background. Haemodynamic and respiratory function after the paravertebral injection of ropivacaine and bupivacaine has not been evaluated previously. The objective of the study was to determine whether there is a clinically significant impairment of circulation and respiration following thoracic paravertebral blockade and whether this potential impairment is different after ropivacaine or bupivacaine. Material and methods. 70 patients scheduled for mastectomy were randomized to receive a single injection of 0.4 ml/kg of 0.5% ropivacaine (n = 35) or 0.5% bupivacaine (n = 35) at the T4 level. Haemodynamic parameters and pulmonary function (evaluated by bedside spirometry) before and after the injection of the local anesthetic were analyzed. Results. Haemodynamic parameters did not change significantly from baseline values. The exception was diastolic blood pressure which increased after ropivacaine (from 77 ± 10 to 82 ± 12 mmHg, P = 0.006) and heart rate which decreased after bupivacaine (from 75 ± 12 to 71 ± 12 beats/min, P = 0.014). FVC and FEV1 decreased similarly in both groups FVC decreased from 2.19 ± 0.74 to 1.92 ± 0.67 L in ropivacaine group (P < 0.05) and from 2.20 ± 0.7 to 1.90 ± 0.70 L in bupivacaine group (P < 0.001), while FEV1 decreased from 1.97 ± 0.61 L to 1.73 ± 0.56 L in ropivacaine group (P < 0.05) and from 1.97 ± 0.62 to 1.66 ± 0.62 L in bupivacaine group (P < 0.001). Conclusions. Paravertebral injection of equal concentrations of bupivacaine or ropivacaine combined with premedication has almost no influence on a circulatory system and produces comparable, not clinically significant impairment of pulmonary function.

HU-EP-19 / 18 HU-Mathematik-2019-03 Functional relations for elliptic polylogarithms

Numerous examples of functional relations for multiple polylogarithms are known. For elliptic polylogarithms, however, tools for the exploration of functional relations are available, but only very few relations are identified. Starting from an approach of Zagier and Gangl, which in turn is based on considerations about an elliptic version of the Bloch group, we explore functional relations between elliptic polylogarithms and link them to the relations which can be derived using the elliptic symbol formalism. The elliptic symbol formalism in turn allows for an alternative proof of the validity of the elliptic Bloch relation. While the five-term identity is the prime example of a functional identity for multiple polylogarithms and implies many dilogarithm identities, the situation in the elliptic setup is more involved: there is no simple elliptic analogue, but rather a whole class of elliptic identities. ar X iv :1 90 6. 11 85 7v 1 [ he pth ] 2 7 Ju n 20 19
Optimal Routing Strategy on Weighted Networks

How to improve the transfer capability of the weighted networks is one of the most important problems in complex networks. In this paper, a novel and effective routing strategy is proposed by deleting edges in proper order according to their different definitions of edge weight. Kicking out few specified edges can enhance the transfer capability of weighted networks greatly. Simulations on both compute generated and real world networks show that the routing strategy kicking out edges according to the product of the strengths of two nodes of the edge is more effective. Moreover, we analyse the curve of critical packet generation rate of kicking out all deletable edges and find that there is a sharp transition after kicking out some edges. Due to the strongly improved network capacity, easy realization on networks, and low cost, the strategy may be useful for real communication networks.

Globally Synchronized Frames for Guaranteed Quality-of-Service in Shared Memory Systems

Resource contention among concurrent threads on multicore platforms results in greater performance variability of individual threads than traditionally seen with time-multiplexed threads on single-core platforms. This performance variability makes it hard to provide performance guarantees, degrades parallel program performance, and burdens software writers by making performance tuning and load balancing more challenging. In this thesis, we propose a novel QoS framework, called Globally Synchronized Frames (GSF), to combat the performance variability problem in shared memory systems. We first apply GSF to a multi-hop on-chip network to provide QoS guarantees of minimum bandwidth and maximum delay for each flow sharing the network. The GSF framework can be easily integrated with a conventional virtual channel (VC) router without significantly increasing the hardware complexity. We then present an extended version of GSF framework to provide end-to-end QoS for cache-coherent shared memory systems, which is called GSF memory system (GSFM). GSFM employs a single unified framework to manage multiple heterogeneous bandwidth resources such as on-chip networks, DRAM banks and DRAM channels, to achieve better hardware efficiency and composability towards end-to-end QoS than component-wise QoS approaches. Finally, we propose the METERG (MEasurement Time Enforcement and Runtime Guarantee) QoS framework. Independent of GSF, the METERG framework provides an easy method to obtain a tight estimate of the upper bound of a program’s execution time for a given resource reservation setting. Our approach is based on simple measurement without involving any expensive program analysis or hardware modeling.
