An Adaptive Frequency Regulation Method With Grid-Friendly Restoration for VSC-HVDC Integrated Offshore Wind Farms

With the rapid growth of voltage source converter based high-voltage direct current (VSC-HVdc)-integrated offshore wind farms, wind turbines (WTs), and VSC stations are required to provide frequency regulation to maintain the onshore system frequency stability. However, after a temporary power increase during the initial period of a disturbance, WTs and VSC stations must reduce their output power to restore their own initial operating states. If there is no other power injection to offset the corresponding power shortage, a significant second frequency drop (SFD) may occur. To address this issue, this paper proposes an adaptive frequency regulation method with grid-friendly restoration. Different frequency regulation strategies are designed to adaptively use the releasable kinetic energy in WTs or the electrostatic energy in VSC stations according to their own real-time operating status. In addition, a system-level grid-friendly coordination is proposed to use the persistent energy reserves of WTs with a deloading strategy to increase the instantaneous power injection and avoid a significant SFD while other WTs or VSC stations restore their operating states. The quantitative calculation and switching mechanism of the additional power injections of deloading WTs are highlighted, and the effectiveness of the proposed method is verified in a case study.
Control problems for one-dimensional fluids and reactive fluids with moving interfaces

The purpose of this paper is to expose several recent challenging control problems for mono-dimensional ﬂuids or reactive ﬂuids. These problems have in common the existence of a moving interface separating two spatial zones where the dynamics are rather diﬀerent. All these problems are grounded on topics of engineering interest. The aim of the author is to expose the main control issues, possible solutions and to spur an interest for other future contributors. As will appear, mobile interfaces play key roles in various problems, and truly capture main phenomena at stake in the dynamics of the considered systems.
An Efficient Adaptive Thresholding Technique for Wavelet Based Image Denoising

This frame work describes a computationally more efficient and adaptive threshold estimation method for image denoising in the wavelet domain based on Generalized Gaussian Distribution (GGD) modeling of subband coefficients. In this proposed method, the choice of the threshold estimation is carried out by analysing the statistical parameters of the wavelet subband coefficients like standard deviation, arithmetic mean and geometrical mean. The noisy image is first decomposed into many levels to obtain different frequency bands. Then soft thresholding method is used to remove the noisy coefficients, by fixing the optimum thresholding value by the proposed method. Experimental results on several test images by using this method show that this method yields significantly superior image quality and better Peak Signal to Noise Ratio (PSNR). Here, to prove the efficiency of this method in image denoising, we have compared this with various denoising methods like wiener filter, Average filter, VisuShrink and BayesShrink. Keywords—Wavelet Transform, Gaussian Noise, Image Denoising, Filter Banks and Thresholding.

The current status of MICE will be described.
Open- and Short-Circuit Fault Identification for a Boost dc/dc Converter in PV MPPT Systems

This paper proposes a fault identification system for short and open-circuit switch faults (SOCSF) for a dc/dc converter acting as a Maximum Power Point Tracker (MPPT) in Photovoltaic (PV) systems. A closed-loop operation is assumed for the boost dc/dc converter. A linearizing control plus a Proportional-Derivative (PD) controller is suggested for PV voltage regulation at the maximum power point (MPP). In this study, the SOCSF are modeled by using an additive fault representation and the fault identification (FI) system is synthesized departing from a Luenberger observer. Hence, an FI signal is obtained, which is insensitive to irradiance and load current changes, but affected by the SOCSF. For FI purposes, only the sensors used in the control system are needed. Finally, an experimental evaluation is presented by using a solar array simulator dc power supply and a boost dc/dc converter of 175 W in order to validate the ideas this study exposes.
Ensemble Forecasting of Tropical Cyclone Motion Using a Barotropic Model. Part II: Perturbations of the Vortex

In Part I of this study, the technique of ensemble forecasting is applied to the problem of tropical cyclone motion prediction by perturbing the environmental ﬂow. In this part, the focus is shifted to perturbation of the vortex structure. The same barotropic model as in Part I is used to predict 66 cases from the Tropical Cyclone Motion (TCM-90) experiment. Two series of experiments are performed. The ﬁrst consists of the Monte Carlo forecast for the vortex (MCFV), lagged-average forecast for the vortex (LAFV), and breeding of growing modes for the vortex (BGMV). These are applied to the original analyses without adding any synthetic vortex, and their techniques of generating perturbations are similar to those in Part I. The second series adopts a technique that simulates uncertainties in estimating the synthetic vortex structure. The effect of adding an initial position error (IPER) is ﬁrst explored. Then a set of four experiments (BETA) is carried out to study the consequence of perturbing the persistence vector and/or various parameters used to generate the (cid:98) gyres in a spun-up vortex. Response of the model forecasts to random noise added in the experiment MCFV is found to be low, and the ensemble mean is thus always close to the control forecast. The situation is similar when the rms size of the noise is slightly varied, or when its characteristic length scale is changed. The skill of the IPER experiment also differs little from the control forecast. The remaining experiments other than the MCFV and IPER show a similar average skill to one another when veriﬁed both under the perfect model assumption (PMA) and by the best tracks. In the PMA veriﬁcation, potential improvement over the control forecast can be obtained by the ensemble mean in the LAFV, BGMV, and some sets of the BETA experiments. However, some failure cases are found in the LAFV and BGMV experiments when the vorticity center cannot be well identiﬁed during the model integration. When compared with the best tracks, a portion of the cases can still outperform the control in the LAFV, BGMV, and BETA experiments. Since different control forecasts are used in different experiments, the forecast errors are scaled to the same benchmark before they are compared. It is found that among the BETA experiments, the conﬁguration with the best performance is to perturb the parameters for generating the (cid:98) gyres and persistence vector simultaneously. It can outperform LAFV after 48 h and has comparable performance with BGMV. This set of BETA ensemble may therefore be suitable for substituting BGMV when a synthetic vortex is necessary. Another implication is that since the persistence vector represents an improved large-scale ﬂow, potential skill should exist for combining the perturbed (cid:98) gyres with the environmental perturbations used in Part I.
The Effect of Oral Corrective Feedback on Beginner and Low Intermediate Students’ Speaking Achievement

Oral corrective feedback (CF) and its subsequent impact on learning are main areas of current research on language learning and have attracted a lot of attention. There is a considerable amount of research investigating corrective feedback and error. What has not been researched extensively yet and is the focus of this study, is the effect of oral corrective feedback on students’ speaking achievement in Iranian schools. To this end, 370 Iranian EFL learners were chosen through multistage cluster sampling. Male students in Junior high schools of Zanjan city (n= 7936) were considered as the total size of the population being studied. They were in the seventh and ninth grades of Iranzamin, Sama, and Baharestan junior high schools in Zanjan-Iran. Cambridge Proficiency Test was used in order to have homogeneous groups. In the pretest the school speaking test was employed to measure their speaking skill. After six weeks of treatment, the speaking test was administered as a posttest. According to results, there were significant differences between the speaking mean scores in the posttest compared with the pretest; therefore, it was concluded that the oral corrective feedback had a positive effect on students’ speaking achievement. Pedagogical implications were extracted to assist English language instructors to be aware of the usefulness and value of the different kinds of oral corrective feedback, to effectively establish the necessary activities in the classroom, and to successfully supply the students with the appropriate kind of oral corrective feedback.

Will Smart Cars Drive on Smart Roads? About Sensor Systems in Asphalt Concrete

Developments in smart and automated driving raise questions about the future requirements of infrastructure. It is highly likely that advances in transport will require close to real-time information on the condition of roads. The recent, speedy development of sensors may lead to the development of Smart Roads and in so doing, provide the necessary real-time data. It is within this context that passive RFID sensors were tested in a series of experiments to ascertain their suitability to measure asphalt concrete mix temperature during construction and afterwards during the life of the pavement. Laboratory tests focused on the proper placement of the sensor in the asphalt concrete layer and studying the latter’s influence on the sensor. Field experiments focused on the suitability to measure temperature, traceability, robustness, and accuracy of the technology. The results show that reliable temperature measuring with passive RFID tags is possible. The sensors are robust, portable, accurate and can be integrated into existing measuring regimes such as determining asphalt concrete cooling rates during construction. While the cost of passive RFID sensors is relatively low, the major disadvantage is that they cannot be read automatically, which is crucial if the information is to be used to follow temperature developments over time or even provide asphalt concrete temperature information to vehicles in order to warn for extreme road conditions. Ongoing experiments with fiber optic sensors indicate that there may be other ways to measure temperature and possibly combine this with performance indicators such as strain.
Transparency and Conflict Resolution Automation Reliability in Air Trffic Control

This paper investigates the automation reliability and the transparency in automation conflict resolution advisories for air traffic control. Four general effects: those of traffic load, those of expertise and, those of imperfect automation and its mitigation by automation transparency in the context of the lumberjack analogy were examined. The results showed that the two automation functions, the conflict resolution advisor (CRA) and the vertical situation display (VSD) offer benefits for both novice and professional controllers’s performance and increased situation awareness across traffic loads, even when the former is of imperfect reliability.
This information is current as Cancer-Induced Immune Suppression Eradicate Established Tumors despite Adoptively Transferred Immune T Cells

Myeloid-derived CD11b + Gr1 + suppressor cells (MDSCs) and tumor-associated macrophages (TAMs) are considered a major obstacle for effective adoptive T cell therapy. Myeloid cells suppress naive T cell proliferation ex vivo and can prevent the generation of T cell responses in vivo. We ﬁnd, however, that adoptively transferred immune T cells eradicate well-established tumors in the presence of MDSCs and TAMs, which are strongly immunosuppressive ex vivo. These MDSCs and TAMs were comparable in numbers and immunosuppressive capacity among different tumor models. Longitudinal microscopy of tumors in vivo revealed that after T cell transfer, tumor vasculature and cancer cells disappeared simultaneously. During T cell–mediated tumor destruction, the tumor stroma contained abundant myeloid cells (mainly TAMs) that retained their suppressive properties. Preimmunized but not naive mice resisted immune suppression caused by an unrelated tumor burden, supporting the idea that in vivo, myeloid immunosuppressive cells can suppress naive but not memory T cell responses.

stelaCSF: a unified model of contrast sensitivity as the function of spatio-temporal frequency, eccentricity, luminance and area

contrast many The existing CSFs typically account for a subset of relevant dimensions describing a stimulus, limiting the use of such functions to either static or foveal content but not both. In this paper, we propose a unified CSF, stelaCSF, which accounts for all major dimensions of the stimulus: spatial and temporal frequency, eccentricity, luminance, and area. To model the 5- dimensional space of contrast sensitivity, we combined data from 11 papers, each of which studied a subset of this space. While previously proposed CSFs were fitted to a single dataset, stelaCSF can predict the data from all these studies using the same set of parameters. The predictions are accurate in the entire domain, including low frequencies. In addition, stelaCSF relies on psychophysical models and experimental evidence to explain the major interactions between the 5 dimensions of the CSF. We demonstrate the utility of our new CSF in a flicker detection metric and in foveated rendering.
E V ect of sub-lethal damage to juvenile colonies of massive Porites spp. under contrasting regimes of temperature and water X ow

In this study, juvenile colonies of massive Porites spp. (a combination of P. lutea and P. lobata ) from the lagoon of Moorea (W 149°50 (cid:1) , S 17°30 (cid:1) ) were damaged and exposed to contrasting conditions of temperature and X ow to evaluate how damage and abiotic conditions interact to a V ect growth, physiological performance, and recovery. The experiment was conducted in April and May 2008 and consisted of two treatments in which corals were either undamaged (controls) or damaged through gouging of tissue and skeleton in a discrete spot mimicking the e V ects of corallivorous W shes that utilize an excavating feeding mode. The two groups of corals were incubated for 10 days in microcosms that crossed levels of temperature (26.7 and 29.6°C) and X ow (6 and 21 cm s ¡ 1 ), and the response assessed as overall colony growth (change in weight), dark-adapted quantum yield of PSII ( F v / F m ), and healing of the gouged areas. The in X uence of damage on growth was a V ected by temperature, but not by X ow. When averaged across X ow treatments, damage promoted growth by 25% at 26.7°C, but caused a 25% inhibition at 29.6°C. The damage also a V ected F v / F m in a pattern that di V ered between X ow speeds, with a 10% reduction at 6 cm s ¡ 1 , but a 4% increase at 21 cm s ¡ 1 . Regardless of damage, F v / F m at 21 cm s ¡ 1 was 11% lower at 26.7°C than at 29.6°C, but was una V ected by temperature at 6 cm s ¡ 1 . The lesions declined in area at similar rates (4–5% day ¡ 1 ) under all conditions, although the tissue within them regained a normal appearance most rapidly at 26.7°C and 6 cm s ¡ 1 . These W ndings show that the response of poritid corals to sub-lethal damage is dependent partly on abiotic conditions, and they are consistent with the hypothesis that following damage, calci-W cation and photosynthesis can compete for metabolites necessary for repair, with the outcome a V ected by X ow-mediated mass transfer. These results may shed light upon the ways in which poritid corals respond to biting by certain corallivorous W shes.
Journal of Cell and Animal Biology

immunology, and This study evaluated the effects of aqueous seed extract of Parkia biglobosa on the micro-anatomy of the testis and sperm profile of adult Wistar rats. Twenty-one male Wistar rats weighing between 96 and 120 g were assigned into three groups A, B, and C (n=7). Group A was the control and received normal saline, while the animals in groups B and C were treated with 300 and 500 mg/kg body weight (Bwt) aqueous seed extract of P. biglobosa orally and daily for 30 days. The animals were sacrificed via cervical dislocation at the end of the administration, and the testes were extracted for micro anatomical and histochemical studies. The Makler counting chamber was used for semen analysis while the Hematoxylin and Eosin (H and E) stain was used to assess the microstructure of the testicular tissues. The result from semen analysis showed a significant increase (p<0.05) in sperm motility, vitality, and morphology in the group treated with 300 mg/kg Bwt when compared with the control. The group treated with 500 mg/kg Bwt, showed a significant decrease in sperm motility, vitality, and morphology when compared with the control. H and E studies revealed the increased thickness of the germ cell layers of the seminiferous tubules (ST), with an increased number of spermatozoa in the lumen of ST in the group treated with 300 mg/kg bwt compared to the control group. This is a biomarker for improved spermatogenic activity in testicular tissues. Ingesting of P. biglobosa in the conditions used in this study seems to be safe and improves sperm parameters at a low dose (300 mg/kg Bwt).
