Design and Real Time Digital Simulator Implementation of a Takagi Sugeno Fuzzy Controller for Battery Management in Photovoltaic Energy System Application

This paper presents a acomprehensive design and control strategy for a photovoltaic (PV) energy storage system. The system consists of a 2kW photovoltaic system, two converter circuits, a resistive load of 6 Ohm and a lithium-ion battery storage integrated with DC Bus applying constant power to the resistive load. This scheme offered two converter topologies, one is a boost converter and another is a DC/DC bidirectional converter. The boost converter is directly connected in series to the PV array whereas the bidirectional DC/DC converter (BDC) is connected to the battery. The boost converter is used to regulate the maximum power point tracking (MPPT) of the PV array. Closed-loop control of the bidirectional controller is implemented with Takagi-Sugeno Fuzzy (TS-Fuzzy) controller to regulate the battery charging and discharging power flow. The proposed scheme provides a good stabilization in the DC bus volatge. Simulation results of the proposed control schema under MATLAB/Simulink are presented and compared with the Proportional Integral (PI) controller. The simulation results obtained from MATLAB are verified on Real Time
A simulated annealing procedure based on the ABC Shadow algorithm for statistical inference of point processes

Recently a new algorithm for sampling posteriors of unnormalised probability densities, called ABC Shadow, was proposed in [8]. This talk introduces a global optimisation procedure based on the ABC Shadow simulation dynamics. First the general method is explained, and then results on simulated and real data are presented. The method is rather general, in the sense that it applies for probability densities that are continuously differentiable with respect to their parameters
Incremental approach to computation of elementary siphons for arbitrary simple sequential processes with resources

Computation of elementary siphons proposed by Li et al. is essential for deadlock control and expensive since complete siphon enumeration of the Petri net is needed, and the number of strict minimal siphons (SMS) grows quickly and exponentially with the size of the net. They assumed that the siphon constructed from each resource circuit is an elementary one and proposed a polynomial algorithm to compute elementary siphons. However, the author demonstrates a counter example where there may be an exponential number of resource circuits. Hence, constructing elementary siphons from resource circuits will result in an exponential number of elementary siphons, which is wrong. The author then develops a polynomial algorithm to find elementary siphons, which also constructs all SMS on the way. This is because, in the method proposed by Li et al., a linear algebraic expression must be established for each dependent siphon, which implies, all SMS must be located. However, all elementary siphons with polynomial complexity can be located.
Predictive System Reconfiguration for Fulfillment of Future Mission Requirements

Equipment failures can cause major disruptions to system operations. Although this is the case for engineered systems in general, it is especially applicable to autonomous systems as an operation or maintenance crew may not be available to remediate the situation during operation. Autonomous vehicles, for instance, may be performing critical missions miles away from the nearest manned support personnel when a failure occurs. In this work we propose and test an approach for automated predictive reconfiguration of an autonomous vehicle with the goal of delaying the occurrence of failures that would otherwise compromise mission accomplishment. The proposed approach is based on the Monte Carlo Tree Search (MCTS) method and assumes the availability of models describing relevant failure mechanisms and the relation between degradation and performance for each failure mode. Our solution introduces novel means for taking into account the uncertainty resulting from estimation of relevant parameters and states , with benefits in terms of reduction of computational cost compared to existing solutions. The proposed approach is successfully tested in a simulation environment.
Synchronization of chaotic injected-laser systems and its application to optical cryptography

We demonstrate that two chaotic systems, each made by two coupled semiconductor lasers, can be synchronized using direct-optical feedback. The robustness of the proposed synchronization scheme against mismatch of source parameters and difference in starting conditions is tested by numerical simulations. Applications to secure data transmission are proposed, namely chaotic masking and chaotic shift keying (CSK).
The Crystal Structures of the System Palladium-Hydrogen

Crystal structures of the system palladium-hydrogen. ---Palladium in the form of a fine wire, 1/4 mm diam. , or of a narrow strip 1/20 mm thick, was more or less saturated with hydrogen and used to diffract x-rays of known wave-length as in the well-known powder method. Two crystal structures were present, both having a face-centered cubic arrangement of atoms. One, that of pure palladium, has a parameter 3.900 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}8}$ cm, while the other, that of hydrogen-saturated palladium, has a parameter varying between 4.000 and 4.039 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}8}$ cm, depending on the degree of saturation. A value near the upper limit, say 4.036 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}8}$ cm, probably corresponds to a compound ${\mathrm{Pd}}_{2}H$, with a density of 10.76 gm/${\mathrm{cm}}^{3}$. The arrangement of atoms may be as in ${\mathrm{Cu}}_{2}$O, but there is no x-ray evidence for the positions of the hydrogen atoms. Stability. All the evidence so far obtained indicates that in the absence of sufficient free atomic hydrogen, the saturated state is unstable or metastable and that return to the hydrogen-free condition once initiated in any crystal proceeds rapidly to the end; also pure palladium is unstable in the presence of atomic hydrogen.
Two-dimensional Spectroscopy Reveals an Arc of Extended Emission in the Gravitational Lens System Q2237+0305

We present two-dimensional spectroscopy of the gravitational lens system Q2237+0305 (Einstein Cross) obtained with the INTEGRAL fiber system in subarcsecond seeing conditions. The four components of the system appear clearly separated in the continuum intensity maps. However, the intensity map of the C III] λ1909 line exhibits an arc of extended emission connecting the A, D, and B components. This result can be explained if, as is usually assumed, the continuum arises from a compact source ≲0.05 pc in extent in the nucleus of the object while the line emission comes from a much larger region. A lens model fitted to the positions of the four compact images also accounts for the arc morphology. In the framework of this model, the region generating the C III] λ1909 emission would have dimensions of about 400 h-1 pc across. We interpret the observed arc as a gravitational lens image of the extended narrow line region of the source.
Image data compression by adaptive vector quantization of classified wavelet coefficients

The paper deals with a novel technique for image data compression based on adaptive vector quantization of wavelet coefficients. High compression factors can be achieved without loosing the informative content of each subband for the statistical properties of these coefficients. Performance of this approach, evaluated on a wide variety of pictures, is far better than the JPEG one, both in quantitative terms (PSNR) and in qualitative ones (absence of blockness distortion).
Energy dissipation mechanisms in wave breaking processes: Spilling and highly aerated plunging breaking events

[1] The breaking of free surface waves is investigated numerically via a Navier-Stokes model for the two-fluids flow of air and water. Third order Stokes waves in a periodic domain are simulated. The fundamental wavelength is 27 cm, whereas the initial steepness varies from low values, leading to regular wave trains, up to artificially steep wave trains yielding plunging breaking events. Attention is focused on the early stage of the breaking, when most of the energy is dissipated. The energy content in air, the fraction associated to surface tension effects, the viscous dissipation in water, and the work done against the pressure field are analyzed in order to distinguish the different contributions to the dissipation. Vorticity fields and dissipation contours are also presented. In the spilling case, the extra energy content with respect to the steepest nonbreaking case focusses into the breaking region and is gradually dissipated. Once the extra energy has been dissipated, the resulting wave matches the steepest nonbreaking solution. In the plunging case, an important role is played by the air entrainment. A fraction between 10 to 35% of the energy dissipated by the breaking is spent in entraining the air cavity, and most of it is dissipated by viscous effects when the cavity collapses. The phenomenon is clearly highlighted by sequences of vorticity and dissipation contours. The circulation and the area of the cavity generated by the plunging of the jet are provided, and parametric dependencies are proposed.
CCD observations of Abell clusters. V, Isophotometry of 175 brightest elliptical galaxies in Abell clusters

Profiles of major- and minor-axis surface brightness, ellipticity, position angle, and isophote centroid are presently derived from isophotometry for a sample of 175 brightest cluster ellipticals (BCEs). The BCEs' average ellipticity is a sharply rising function of metric radius; less than a fourth of the sample exhibits significant ellipticity decrease with increasing radius. While at radii of less than 16 kpc the BCEs are rounder than the average elliptical, they become too flattened at radii greater than 30 kpc to represent a randomly-oriented oblate-spheroid population. These results indicate that BCE outer regions are dynamically strongly coupled to their either prolate or stringy clusters. 136 refs.
A parametric error analysis of the backward integration method for reverberation time estimation

Backward integration of a room impulse response has long been used in room acoustics for the estimation of reverberation time. However, the inevitable noise floor limits the minimum level of the measured impulse response, thereby leading to errors. This paper shows how the error is influenced by the selection of truncation time and evaluation range. A general guideline that emerges from this study is to truncate the measured impulse response at the knee where the main decay slope intersects the noise floor, then measure the slope of the backward integrated truncated impulse response down to a level about 5 dB above the noise floor.
Can the Method of Reflections help predict future growth

Building upon an original and fruitful research line, a recent paper by Hidalgo and Hausmann (2009) proposed new indicators of product sophistication and economic complexity build solely upon international trade data, in their Method of Reflections. The authors find their indicators for economic complexity to be highly related to countries’ income and show evidence supporting their use as predictors of future growth in the short and long run. This would make these indicators very appealing to empirical economists and policy-makers. This work tests these properties for the indicators constructing them upon a more disaggregated database and changing some other important methodological decisions. Results show that MR indicators are strongly related to income and they can be considered good predictors of long-term growth under certain conditions. Evidence supporting MR indicators as good predictors of short-term growth could not be found.
Comparing Children's Fears in Alabama: An Investigation Using Post-9/11 and Post-Invasion of Iraq Data.

This study was designed to investigate the fears of children and adolescents in Alabama in the aftermath of 9/11 and after the initial invasion of Iraq in 2003. The American Fear Survey Schedule for Children (FSSC-AM; Burnham, 1995, 2005) was utilized to measure the fears of youth in Grades 2-12. Introduction Children and adolescents in Alabama are directly exposed to traumatic events at school (e.g., guns, fights, threatening situations), in communities (e.g., tornadoes, hurricanes, drive-by shootings, homes destroyed by fire, disappearance of Natalee Holloway in Aruba), and with family members (e.g., arguments, illness, divorce, death). Youth in Alabama are also indirectly exposed to various media accounts of national and global trauma. For example, over the past ten years, national media coverage has included footage of the bombing of the Alfred Murrah Federal Building in Oklahoma City, the Columbine High School shootings, 9/11, the invasion of Iraq, the Asian tsunami, and Hurricane Katrina. Even though the latter events were not close in vicinity to children and adolescents in Alabama, with the exception of Hurricane Katrina, studies have shown that media exposure to traumatic events can be distressful, even at a distance Correspondence should be addressed to :Joy J.

Investigation of the effect of nanoparticles on wood-bioplastic composite behavior using the acoustic emission method

Acoustic emission (AE) is a non-destructive method capable of detecting various fracture micromechanisms in composite materials. Discrimination of AE signals associated with various fracture modes is of interest when utilizing this technique. Thus, this paper investigates the identification of AE signal processing wavelet packet transform (WPT) failure mechanisms in wood-bioplastic nanocomposites. To this end, nanocomposites with different compositions were prepared and tested according to the ASTM D638 standard. AE signals were collected during the experiment, and analyzed by various methods. The fast Fourier transform method was used to analyze the fracture of polymers and wood and determine the frequency range of fracture. Additionally, a time-frequency analysis of the AE signal generated by the WPT was performed. The energy distribution criterion was employed to determine the main components of the various damage micromechanisms. The results reveal distinct types and percentages of failure micromechanisms in various composites. This method examined the effect of nanoparticles on the matrix’s tensile strength. The scanning electron microscopy method was used to study the morphology of composites and mechanism of failure. The phase composition of the produced materials was examined with X-ray energy dispersive spectroscopy. The results demonstrated the proposed techniques show a good performance in computational damage discrimination.

Selection of sensors and actuators based on a sufficient condition for robust performance

A new method for selecting sensors and actuators for linear control system applications is proposed. The goal is to eliminate actuator/sensor combinations for which a controller achieving a desired robust stability or robust performance level cannot be designed. To account for the structured uncertainty block, the plants for all candidate combinations are extended with certain scaling filters. Each combination is subjected to six conditions for existence of a stabilizing controller meeting a required H∞ norm bound. However, combinations may be incorrectly rejected, since optimality of the scaling filters is not guaranteed. An active suspension control problem is used as an illustrative example.
Into the Black Box: Tracing Information About Risks Related to 10 Evolutionary Problems

Human behavioral risk-seeking tendencies differ across content domains. How can such behavioral differences be reliably produced by the cognitive system? This article presents an explorative analysis of the reasons for and cognitive mechanisms underlying different risk propensities across 10 evolutionary domains. We investigate three cognitive process models: Tally, Take The First, and Most Relevant. Tally assumes decision-makers use majority rules. Take The First assumes decision makers rely on the first piece of information that comes to mind. Most Relevant assumes decision makers rely on information that is important in their environment. A survey with a total of N = 120 individuals in the United States gathered 1,598 self-reported memory-based attributes of risky situations in 10 evolutionary content domains. The explorative analysis of the cognitive processes underlying the domain differences suggest that the Most Relevant strategy is most closely related to the shifts in risk seeking across content domains, and that Take The First is also related, but the Tally process is not related to domain differences in risk propensities. This means that a cognitive process that relies on the first or frequent pieces of information from the environment may be underlying domain differences in risk taking.
Estimation d'état des systèmes non linéaires incertains sous forme multimodèle de type Takagi-Sugeno

Cet article traite le probleme de la conception d'un observateur d'etat pour un systeme non lineaire decrit par un modele de Takagi-Sugeno (T-S). La particularite de ce travail reside dans la consideration de l'hypo- these de non mesurabilite des variables de decision ou de premisse. De plus, le modele T-S considere est suppose incertain et a mesures bruitees. On est alors face a un probleme de conception d'observateur pour un systeme T-S incertain et a variables de decision non mesurables. Deux approches sont proposees, elles se basent sur l'utilisation de la seconde theorie de Lyapu- nov combinee aux techniques d'optimisation L2. Les conditions de stabilite et de convergence de l'erreur d'estimation d'etat sont formulees en terme d'inegalites lineaires matricielles (LMI). Un exemple academique est pro- pose afin d'illustrer les performances des approches proposees. Enfin, la seconde approche est appliquee a un modele d'un bioprocede.
Management of Trigeminal Neuralgia with Botulinum Toxin Type A: Report of Two Cases

Trigeminal neuralgia is a chronic pain condition associated with sharp, shock-like pain in one or more divisions of the trigeminal nerve. For patients who do not respond well to pharmacotherapy, there is growing evidence that Botulinum toxin type A injections into the trigeminal ganglion provide pain relief for several weeks up to several months at a time. One option is to administer injections into the trigeminal ganglion in Meckel’s cave by inserting a needle through the Pterygopalatine Fossa using fluoroscopy to guide and confirm the proper needle placement. However, there is evidence that Botulinum toxin travels across nerve synapses; thus, injecting directly into the trigeminal ganglion may not be necessary. We present two patients with a confirmed diagnosis of trigeminal neuralgia who were treated by injecting Botulinum toxin type A intraorally into the mental foramen which resulted in 6 months or longer of pain relief. Injections into the mental foramen are much easier to administer than those administered directly into the trigeminal ganglion, and both patients treated with this technique experienced comparable results to what can be expected from traditional fluoroscopy-guided botulinum toxin injections. Though more research is needed, these cases potentially imply that a less-invasive injection may be sufficient in managing trigeminal neuralgia-related pain.
Micro-/Nano-Structured Biodegradable Pressure Sensors for Biomedical Applications

The interest in biodegradable pressure sensors in the biomedical field is growing because of their temporary existence in wearable and implantable applications without any biocompatibility issues. In contrast to the limited sensing performance and biocompatibility of initially developed biodegradable pressure sensors, device performances and functionalities have drastically improved owing to the recent developments in micro-/nano-technologies including device structures and materials. Thus, there is greater possibility of their use in diagnosis and healthcare applications. This review article summarizes the recent advances in micro-/nano-structured biodegradable pressure sensor devices. In particular, we focus on the considerable improvement in performance and functionality at the device-level that has been achieved by adapting the geometrical design parameters in the micro- and nano-meter range. First, the material choices and sensing mechanisms available for fabricating micro-/nano-structured biodegradable pressure sensor devices are discussed. Then, this is followed by a historical development in the biodegradable pressure sensors. In particular, we highlight not only the fabrication methods and performances of the sensor device, but also their biocompatibility. Finally, we intoduce the recent examples of the micro/nano-structured biodegradable pressure sensor for biomedical applications.
Internet Addiction In Malaysia: An Overview Of Uses And Gratifications Theory (Ugt)

People have grown increasingly attracted to, and even obsessed with, the Internet as technology has evolved and a myriad of applications have appeared. Neurological difficulties, psychological illnesses, social issues, decreased academic success, sleep disruption, excessive daytime sleepiness, and environmental stresses have all been related to excessive Internet use. Due to the widespread use and increase of internet access, researchers have focused on the uses and social implications of the Online, including internet addiction among Malaysians. The current study consists of a peer-reviewed research article on internet addiction that uses the Uses and Gratifications Theory (UGT) to describe the phenomenon. This theory is focused with establishing why individuals use certain sorts of media, what needs they have for them, and how much pleasure they get from utilising them. Therefore, this study aims to identify the predictors of internet addiction and what makes this internet usage so appealing. This study contributes to the body of knowledge on the phenomenon of internet addiction by presenting relevant findings on the determinants of internet addiction in Malaysia, which are not previously available. This research will also serve as a guideline for parents, educators, and other interested parties in dealing with the issues and planning for the intervention program, which will focus on young adults.
