Optimal operation of a virtual power plant

The increase in the amount of generators based on renewable energy sources (RES) in the power system is leading to many changes in its operation. Since the RES depends on weather conditions, coordinating the operation of the entire power system has become a more complex issue. New challenges need to be faced in order to supply the electric energy to the customers at the appropriate quality level. In this paper the concept and architecture of a complex Virtual Power Plant (VPP) will be introduced and discussed. The focus will be paid to the optimization of the structure of the VPP as well as to its optimal operation. The result of the optimization have been presented and discussed in the paper taking into account different operation scenarios.
COMPARISION OF DYNAMIC CYCLING VS STATIC CYCLING ON ENDURANCE, BALANCE, AND WALKING ABILITY OF CHILDREN WITH CEREBRAL PALSY

Results: All the 3 groups showed significant pre to post improvement for the entire outcomes measured but GMFM-66. Results of the studied showed more significant improvement in both the cycling groups compared to the control group; Dynamic cycling group showing better response than static cycling group. Though all the groups showed improvement in GMFM-66, the dynamic cycling group showed better improvement followed by control group. Conclusion: Dynamic cycling incorporated with conventional exercises improves the cardiovascular endurance, balance and functional abilities than conventional exercises only.
Measurement-based analysis of the throughput-power level trade-off with modulated multisine signals in a SWIPT system

Simultaneous wireless information and power transfer (SWIPT) has gained interest, especially due to its applicability in the world of Internet of Things. For pure wireless power transfer (WPT), multisine signals have already been shown to increase RF-to-DC power conversion efficiency (PCE) at the receiver which is key in WPT research. In a SWIPT system where the waveforms are modulated for information transfer, however, we expect the modulation scheme to impact both data transmission quality and WPT subsystem efficiency. This paper quantifies by means of an experimental study the impact of QAM and PSK modulated multisine signals, on the power and data transfer efficiency of a SWIPT system, taking into account the often neglected transmitter distortion. Error vector magnitude (EVM) is used as figure of merit for the impact of data transfer efficiency, output voltage ripple for the modulation's impact on WPT.
Fluoride varnish programmes for adolescents at school – caries, conceptions and costs

The overall aim of this thesis was to study the effects on caries, conceptions and costs of school-based fluoride varnish programmes for adolescents in Sweden. Paper I was a 3.5-year randomised controlled study of 1,143 adolescents, in a low caries prevalence area. Two fluoride varnishes, Bifluorid 12 and Duraphat, were compared, with a variation in the frequency of application. In Papers II and III, 26 adolescents and 15 dental nurses were interviewed and asked to describe their experiences as participants or performers in a fluoride varnish programme at school. Paper IV was an evaluation of a school-based fluoride varnish programme, implemented on a broad scale for all 12to 15-year-olds in a region in Sweden and caries data on 27,943 adolescents were analysed retrospectively. The results revealed no statistically significant differences in caries increment between Bifluorid 12 and Duraphat, after fluoride varnish applications every six months. The adolescents experienced taking part as positive, but had feelings of exposure, peer pressure and a lack of information during the programme. The dental nurses had positive experiences of meeting adolescents in a context in which the adolescents were comfortable and relaxed with an opportunity to identify individuals with poor dental health. The caries increment was significantly lower, with a prevented fraction of 32%, after the implementation of a fluoride varnish programme in a large region. A break-even was shown between costs and gains due to prevented fillings at the age of 15. The main conclusions were that a school-based fluoride varnish programme for all 12to 15-year-olds, implemented on a broad scale in a large region, appeared to affect the approximal caries increment in a positive way. The cost of the programme was similar to the cost of the avoided fillings, during the fouryear study period, which suggests good cost effectiveness in both the short and long perspective. The adolescents had mainly positive experiences of participating in a school-based fluoride varnish programme, although a desire for greater respect of their integrity was noted. Dental nurses described a feeling of professional development originating from the challenges associated with working in an arena outside the dental clinic.
Is the Correlation between Storage Capacity and Matrix Reasoning Driven by the Storage of Partial Solutions? A Pilot Study of an Experimental Approach

Working memory capacity (WMC) and reasoning abilities—as assessed by figural matrices tests—are substantially correlated. It is controversially discussed whether this correlation is only caused by controlled attention or also by storage capacity. This study aims at investigating storage of partial solutions as a possible mechanism by which storage capacity may contribute to solving figural matrices tests. For this purpose, we analyzed how an experimental manipulation of storage demands changes the pattern of correlations between WMC and performance in a matrix task. We manipulated the storage demands by applying two test formats: one providing the externalization of partial solutions and one without the possibility of externalization. Storage capacity was assessed by different types of change detection tasks. We found substantial correlations between storage capacity and matrices test performance, but they were of comparable size for both test formats. We take this as evidence that the necessity to store partial solutions is not the limiting factor which causes the association between storage capacity and matrices test. It is discussed how this approach can be used to investigate alternative mechanisms by that storage may influence performance in matrices tests.
A Scalable Belief Propagation Algorithm for Radio Signal Based SLAM

We present a simultaneous localization and mapping (SLAM) algorithm that is based on radio signals and the association of specular multipath components (MPCs) with geometric features. Especially in indoor scenarios, localization from radio signals is challenging due to diffuse multipath propagation and the unknown MPC-featureassociation. In our approach, specular reflections at flat surfaces (e.g., walls) are described in terms of virtual anchors (VAs). The positions of these VAs are unknown and possibly time-varying. We develop a Bayesian model of the SLAM problem including the unknown MPC-VA association. We represent this model by a factor graph, which enables the use of the belief propagation (BP) scheme for efficient marginalization of the joint posterior distribution. The resulting BP-based SLAM algorithm detects the VAs and estimates the time-varying position of the mobile agent and the possibly time-varying positions of the VAs, thereby leveraging the MPCs in the radio signal for improved accuracy and robustness of agent localization. A core aspect of the algorithm is BP-based probabilistic MPC-VA association. Moreover, for improved initialization of new VA positions, the states of unobserved potential VAs are modeled as a random finite set and propagated in time by means of a "zero-measurement" probability hypothesis density filter. The proposed BP-based SLAM algorithm has a low computational complexity and scales well in all relevant system parameters. Experimental results using both synthetically generated measurements and realultra-wideband radio signals demonstrate the excellent performance of the algorithm in challenging indoor environments.
Active or passive?: Investigating the impact of robot role in meetings

Meetings are an integral part of the work place and society in general. Research in Computer Supported Cooperative Work attempts to facilitate and make the process of meetings more effective. Our vision is that the incorporation of social robots in such human-human collaborative settings can assist and improve the effectiveness of a meeting. In this paper we present an empirical study in which pairs of participants collaborate in a meeting scenario with a Nao humanoid robot. Using a within-subjects design, we manipulated the robot's role within the meeting as being either “active” versus “passive”/“service-oriented”. Our results show that the more active robot was deemed as more more alive and social, had the participants more emotionally involved and caused more verbal engagement from the participants as compared to a passive service robot. In conclusion, we speculate on the inclusion of a collaborative robot as a meeting partner.
Generation of a cosecant-squared radiation pattern with a superstrate-like leaky-wave antenna

In this paper a planar leaky-wave antenna in a superstrate-like configuration is used to generate a cosecantsquared radiation pattern. As a difference with previous designs based on such configurations, the superstrate here is truncated. In this way an asymmetric illumination of the radiating aperture is achieved, thereby generating the required pattern. The antenna is fed by a waveguide open in the ground plane of the structure. A dispersion analysis is adopted for designing the antenna. Full-wave numerical results validate the proposed approach and structure. The proposed antenna may find application in mobile communication and radar systems.
Fibrotic Response as a Distinguishing Feature of Resistance and Susceptibility to Pulmonary Infection with Mycobacterium tuberculosis in Mice

ABSTRACT The differential susceptibility of inbred mouse strains DBA/2J (susceptible) and C57BL/6J (resistant) to pulmonary tuberculosis following aerosol infection is under complex genetic control. In this report, transcriptional profiling with RNAs from Mycobacterium tuberculosis-infected lungs was used to investigate the physiological response, cell type, and biochemical pathways underlying differential susceptibility to infection. Statistical analysis of cDNA-based microarrays revealed that 1,097 transcripts showed statistically significant changes in abundance (changes of ≥1.5-fold) in at least one of four experimental group comparisons (C57BL/6J [day 0] versus DBA/2J [day 0] mice, C57BL/6J [day 90] versus DBA/2J [day 90] mice, C57BL/6J [day 90] versus C57BL/6J [day 0] mice, or DBA/2J [day 90] versus DBA/2J [day 0] mice). A group of genes showing very high degrees of significance (changes of ≥2.0-fold) displayed enrichment for transcripts associated with tissue remodeling and the fibrotic response. The differential expression of fibrotic response genes (Sparc, Col1a1, Col1a2, Col4a1, and Col4a2) in the infected lungs of the two mouse strains was validated by another microarray platform (Affymetrix oligonucleotide chips) and by reverse transcription-PCR. Furthermore, the differential expression of additional genes known to be associated with fibrosis (Mmp2, Timp1, and Arg1) was also validated by these approaches. Overall, these results identify the differential fibrotic response as a pathological basis for the high susceptibility of DBA/2J mice to pulmonary tuberculosis.
Supporting social album creation with mobile photo-conferencing

In this paper we present a novel mobile photo-conferencing system that enables collocated and remote users to share, converse and interactively construct social albums. Unlike existing lab based solutions, the solution presented in this paper was designed from the ground up to interoperate across existing 3G mobile networks, enabling collocated and distributed collaboration around captured photos.
Coordinated Control of DFIG's Rotor and Grid Side Converters During Network Unbalance

This paper proposes a coordinated control of the rotor side converters (RSCs) and grid side converters (GSCs) of doubly-fed induction generator (DFIG) based wind generation systems under unbalanced voltage conditions. System behaviors and operations of the RSC and GSC under unbalanced voltage are illustrated. To provide enhanced operation, the RSC is controlled to eliminate the torque oscillations at double supply frequency under unbalanced stator supply. The oscillation of the stator output active power is then cancelled by the active power output from the GSC, to ensure constant active power output from the overall DFIG generation system. To provide the required positive and negative sequence currents control for the RSC and GSC, a current control strategy containing a main controller and an auxiliary controller is analyzed. The main controller is implemented in the positive (dq)+ frame without involving positive/negative sequence decomposition whereas the auxiliary controller is implemented in the negative sequence (dq)- frame with negative sequence current extracted. Simulation results using EMTDC/PSCAD are presented for a 2 MW DFIG wind generation system to validate the proposed control scheme and to show the enhanced system operation during unbalanced voltage supply.

Robust fuzzy controller design for model-based discrete ship steering systems subject to multiple variance constraints

This paper presents a fuzzy controller design method based on Takagi-Sugeno fuzzy model for controlling the Nomoto's ship steering systems with nonlinearities. The state variance and output variance constraints are considered for the stochastic behaviors in Nomoto's ship steering model. Also, the state uncertain dynamic is considered, which can be solved by robust control theory. In this paper, a controller is designed by parallel distributed compensation method with satisfying the Lyapunov stability conditions and multiple variance constraints. Finally, the stability conditions are effectively solved by recasting into so-called linear matrix inequality problems. At last, a simulation is provided for the nonlinear ship steering systems whenever the external disturbances and perturbations exist.
A 2-DOF Circular-Resonator-Driven In-Plane Vibratory Grating Laser Scanner

In this paper, we present the design, modeling, fabrication, and measurement results of a microelectromechanical systems (MEMS)-based in-plane vibratory grating scanner driven by a two-degree-of-freedom (2-DOF) comb-driven circular resonator for high-speed laser scanning applications. Diffraction grating driven by a 2-DOF circular resonator has the potential to scan at large amplitudes compared with those driven by a one-degree-of-freedom (1-DOF) comb-driven circular resonator or a 2-DOF electrical comb-driven lateral-to-rotational resonator. We have demonstrated that our prototype device, with a 1-mm-diameter diffraction grating is capable of scanning at 20.289 kHz with an optical scan angle of around 25deg. A refined theoretical model with fewer assumptions is proposed, which can make the prediction of dynamic performance much more accurate.
A Bayesian Approach to Predicting Water Supply and Rehabilitation of Water Distribution Networks

Water distribution network (WDN) consists of several elements the main ones: pipes and valves. The work developed in this article focuses on a water supply prediction in the short and long term. To this end, reliability data were conjugated in decision making tools on water distribution network rehabilitation in a forecasting context. The pipes are static elements that allow the transport of water to customers, while the valves are dynamic components which perform ensure management of water flow. This paper presents a Bayesian approach that allows management of water distribution network based on the evaluation of the reliability of network components. Modeling based on a Static Bayesian Network (SBN) is implemented to analyze qualitatively and quantitatively the availability of water in the different segments of the network. Dynamic Bayesian networks (DBN) are then used to assess the valves reliability as function of time, which allows management of water distribution based on water availability assessment in different segments. Finally an application on data of a fraction of a distribution network supplying a town is presented to show the effectiveness and the strong contribution of Bayesian networks (BN) in this research field.
miR-328-3p enhances the radiosensitivity of osteosarcoma and regulates apoptosis and cell viability via H2AX

Osteosarcoma is a kind of high-risk sarcoma of the skeleton typically observed in people under 25 years old. Currently, radiotherapy is widely applied in cancer treatment. However, osteosarcoma is radioresistant and accordingly new, more effective radiosensitizers are needed. miRNAs have been reported to play an important role in osteosarcoma radiosensitivity. We examined the modulating effect of miR-328-3p in vivo and in vitro. miR-328-3p was downregulated in HOS-2R cells. The overexpression of miR-328-3p enhanced the radiosensitivity of osteosarcoma cells. miR-328-3p inhibited proliferation and promoted apoptosis in osteosarcoma cells under radiation conditions. In cells overexpressing miR-328-3p, H2AX expression was downregulated. We found that miR-328-3p targets H2AX and inhibits its expression. It was concluded, that miR-328-3p enhances the radiosensitization of osteosarcoma following X-ray irradiation, and determined that it directly targets H2AX to regulate radiosensitization.
Some Genetic Determinants of Obesity , Type 2 Diabetes and Dyslipidemias in “ Oman Family Study ”

Complex polygenic diseases result from the interactions of genetic and environmental factors. However, genetic studies are complicated by phenomena such as genetic heterogeneity, variable age at onset and clinical expression, incomplete penetrance, and wide-ranging, illunderstood, environmental triggers (Rannala, 2001). Because genetic influences are less clear-cut, progress in identifying genes implicated in the pathogenesis has been slow and success limited (Frayling, 2007a; Frayling, 2007b; Frayling et al., 2007; DGI, 2007; Scott et al; Sladek et al., 2007; WTCCC; 2007; Zeggini et al., 2007; Zeggini, 2007). The main difficulties associated with studies of complex traits are to achieve the necessary statistical power and reproducibility. In heterogeneous populations, very large sample sizes are required for successful detection of effects of multiple genes, both for association and linkage studies (Frayling, 2007b; Zeginni, 2007; Groop and Lyssenko, 2008).
Ectopic Meis 1 expression in the mouse limb bud alters PD patterning in a Pbx 1-independent manner

During limb development, expression of the TALE homeobox transcription factor Meis1 is activated by retinoic acid in the proximal-most limb bud regions, which give rise to the upper forelimb and hindlimb. Early subdivision of the limb bud into proximal Meis-positive and distal Meis-negative domains is necessary for correct proximo-distal (P-D) limb development in the chick, since ectopic Meis1 overexpression abolishes distal limb structures, produces a proximal shift of limb identities along the P-D axis, and proximalizes distal limb cell affinity properties. To determine whether Meis activity is also required for P-D limb specification in mammals, we generated transgenic mice ectopically expressing Meis1 in the distal limb mesenchyme under the control of the Msx2 promoter. Msx2:Meis1 transgenic mice display altered P-D patterning and shifted P-D Hox gene expression domains, similar to those previously described for the chicken. Meis proteins function in cooperation with PBX factors, another TALE homeodomain subfamily. Meis-Pbx interaction is required for nuclear localization of both proteins in cell culture, and is important for their DNA-binding and transactivation efficiency. During limb development, Pbx1 nuclear expression correlates with the Meis expression domain, and Pbx1 has been proposed as the main Meis partner in this context; however, we found that Pbx1 deficiency did not modify the limb phenotype of Msx2:Meis1 mice. Our results indicate a conserved role of Meis activity in P-D specification of the tetrapod limb and suggest that Pbx function in this context is either not required or is provided by partners other than Pbx1.
Minireviews S 1 P Signaling and De Novo Biosynthesis in Blood Pressure Homeostasis

Initially discovered as abundant components of eukaryotic cell membranes, sphingolipids are now recognized as important bioactive signaling molecules that modulate a variety of cellular functions, including those relevant to cancer and immunologic, inflammatory, and cardiovascular disorders. In this review, we discuss recent advances in our understanding of the role of sphingosine-1-phosphate (S1P) receptors in the regulation of vascular function, and focus on how de novo biosynthesized sphingolipids play a role in blood pressure homeostasis. The therapeutic potential of new drugs that target S1P signaling is also discussed.
Analysis of Personality Traits of Applicants for Cosmetic Surgery

Performing cosmetic surgery on body members, especially on face and mostly on nose, is globally widespread and thus rhinoplasty is commonly practiced in all societies and nations. Each year ten thousands of individuals undergo cosmetic surgery in order to enhance the appearance of their bodies. The objective of this study was to study the personality traits of people who had applied for cosmetic surgery. The sample included 50 participants: 25 applicants for cosmetic surgery and 25 ordinary individuals. All the individuals were examined by NEO personality inventory. The data were analyzed by employing the independent t-test method. The results obtained from the study indicated that applicants for cosmetic surgery do not differ from normal people in characteristics associated with neurosis, desirability, extraversion, and conscientiousness. The results obtained from this research showed a significant difference between the flexibility of the two groups. That is to say, the flexibility of candidates for cosmetic surgery was higher than that of the ordinary people. In sum, it can be concluded that there is no significant difference between the personality characteristics of these individuals and the ordinary ones.
