Examination of data delay and packet loss for wide-area monitoring and control systems

Timely and synchronized phasor data at high resolutions holds a great promise for more responsible and advanced power grid operations. It is expected that the combined effort of developing new application paradigms and the supporting Information and Communication Technology (ICT) will enable the evolutionary change for future transmission grid operation. This paper addresses the design of the supporting ICT system for Wide-Area Monitoring and Control applications considering system performance. The major contribution that distinguishes this paper from previous research efforts in the same area is that this study quantifies the end-to-end data delay and the received packet rate with considerations of different levels of data concentrations. The analysis performed in this paper is not merely limited to the performance issues caused by communication networks but also provides means to view and analyze the overall data delay of the entire supporting ICT system.
A real-time identification scheme of coherent generators based on the WAMS information

With the fast development of WAMS system, we can obtain the real-time information of power system, which makes it possible to realize the real-time transient stability analysis and close-loop control. The coherent generators identification plays an important role in the transient stability analysis on power system. It is the first step to study the stability of a multi-machine power system. So research on a coherent generators identification scheme based on the real-time information is necessary and vital important. This paper proposes an identification scheme of coherent generators which can be applied online based on the WAMS information. The scheme has advantages of little computation, fast identification speed and high accuracy. Besides, a coherency index is also proposed to evaluate the clustering result. The simulation on IEEE standard 39-bus-10-unit system verifies the speed and accuracy of the scheme.
Comparative Study for Biogas Production from Different Wastes

The bulk of our work was performing the anaerobic digestion of wastes rich in organic matter in a laboratory prototype. The two different substrates: the biodegradable waste from landfill and sludge from the wastewater treatment plant by natural lagoon. We surveyed the evolution of the degradation of organic matter of both experiments which are carried in a digester with a capacity one liter, sealed. During the experiments we followed themeasure of the COD (chemical oxygen demand), the volume of biogas formed during the digestion, the temperature and the pH.The biogas produced from the anaerobic digestion of the two substrates is flammable with a percentage of CH4 more than 64%. Comparing the volume of biogas produced during the digestion of the two substrates of digestion we found that the volume collect from the sludge waste is greater than 10 times relative to thevolume of biogas produced with organic matter in the landfill. The volume of biogas produced is always a function of the residence time of digestion and the concentration of organic matter in the experiment. The percentage of decrease in COD of the sludge was estimated at 87.3% and the substrate of the landfill is 82.44%.
Aerobic Fitness of South African Wheelchair Basketball and Rugby Players.

The aim of this study was to evaluate the VO2max, peak blood lactate and peak heart rate among wheelchair basketball and rugby players. Thirty-eight wheelchair basketball and rugby players were purposively selected based on the following criteria: aged 18-50 years, actively involved in a wheelchair sport for at least one year prior to the study and had at least a minimum of 10% loss of function in the lower extremities. Results indicated that the paraplegics had a higher absolute peak VO2 when compared with the quadriplegic groups. When percentage differences were compared, it was evident that the “other” group (34%) and the paraplegic group (27%) were above the average group mean (1564.3 m? /min-1), whilst the other two groups were (21% and 15%) below the group mean, respectively. The results of the study have practical implications for players’ health and sport performance. It is important that athletes suffering from spinal cord injury or any other type of physical impairment establish some type of anaerobic/aerobic fitness specific to their sport. For disabled athletes, sport participation is imperative for optimising their health, functional ability and physical performance.
H∞ control for nonlinear NCS with interval time-varying delay and packet dropouts

This paper presents a new approach to the problems of analysis and synthesis for nonlinear networked control systems(NNCSs) which can be represented by a T-S fuzzy model with consideration of interval-varying delay and packet dropouts. Neither free weighting matrices nor model transformations are employed in the derivation of system stability criteria. Instead, the significant features are to construct an improved Lyapunov function and to introduce an extended Jessen's inequality. The controllers are shown in terms of linear matrices inequalities, which can be computed through solving a convex optimization problem. Simulation result and numerical example shows the effectiveness of the method.
Does Microfinance Reduce Rural Poverty? Evidence Based on Household Panel Data from Northern Ethiopia

This paper evaluates the long-term impact of microfinance credit from the intensity of participation in borrowing. We use a four-round panel data set on 351 farm households that had access to microfinance in northern Ethiopia. Over the years 1997-2006, with three-year intervals, households are observed on key poverty indicators: improvements in annual consumption and housing improvements. The relatively long duration in the panel enables to measure household poverty changes between consecutive periods and see the long-run effects of exposure to microfinance from the intensity of participation borrowing. The fixed-effects model is innovatively modeled to account for potential selection biases due to both time-invariant and time-varying unobserved individual household heterogeneities. Results show that microfinance borrowing indeed causally increased consumption and housing improvements. A more flexible specification that allows for the number of times the household has been in borrowing also shows that repeated borrowing is effectively increasing consumption: the longer the borrowing relationship the larger the effect partly due to lasting credit effects. Impact estimates that do not account for such dynamic effects may therefore undermine the effect of MFI borrowing.
Motor pump group efficiency in a wind energy pumped storage system

Pumped storage systems are more and more involved in renewable energy at high power levels. But in the same time, pumped storage can be successfully used for grid integration of small scale renewable energy sources, such as wind energy. The purpose of this paper is motor control analyze for pump driving, in order to obtain maximum power available for pumping and a higher efficiency of the pump. An induction motor control based on cubic dependency between voltage and frequency is proposed for induction machine in pumped storage applications. A comparison between this control and linear classic control V/Hz is realized in order to see the benefits given by this cubic dependency control. Experimental validation of the proposed control method is presented, in contrast with classical scalar control. Motor-pump group efficiency is improved by implementing appropriate control method for the system.
vitro characterization of cadmium transport along the gastro-intestinal ract of freshwater rainbow trout ( Oncorhynchus mykiss ) oel

An in vitro gut sac technique was used to examine the mechanism(s) of cadmium (Cd) uptake along the gastro-intestinal tract (GIT) of rainbow trout (Oncorhynchus mykiss). The spatial distribution of Cd between three compartments (mucus-binding, mucosal epithelium, and transport into blood space) was determined using a modified Cortland saline containing 50 M Cd (as CdCl2) labeled with 109Cd radiotracer. Taking into account total surface areas, the order of relative importance for total Cd uptake rate was: posterior intestine > anterior intestine > stomach > mid intestine. Cd transport was not inhibited by experimentally reducing fluid transport rates by manipulation of osmotic gradients using mannitol, but was sensitive to internal luminal pressure changes, suggesting a mechanosensitive pathway. Q10 values (1, 11, and 19 ◦C) indicated a facilitated transport of Cd in the anteriorand mid-intestine. The effects of a channel blockers 10 mM Ca on the kinetics of Cd uptake suggest the presence of a common uptake pathway for Cd and Ca in the stomach, anterior-, and mid-intestine. Further evidence of a shared route of entry was found using three Ca channel blockers, lanthanum, verapamil, and nifedipine: both voltage-insensitive and voltagesensitive Ca channels appear to be present in either some, or all portions of the GIT. Elevated Fe (500 M), Mg (50 mM), and Zn (500 M) showed varying degrees of inhibition of Cd transport depending on the compartment and segment of the GIT. Overall it appears that there are multiple sites, and mechanisms, T of r of Cd uptake along the GI
Microwave microfluidic sensor for determination of glucose concentration in water

In this paper, a compact microfluidic biosensor is designed based on a complementary electric-LC resonator coupled with a microstrip line. It is shown that by flowing water-glucose solutions with different concentrations to the sensing area, the resonance property of the resonator is modified. This measurable change in the electromagnetic property is then used to quantify the glucose concentration. A prototype of the designed sensor is fabricated and tested to verify the biosensing concept.
Neural Interactions That Give Rise to Musical Pleasure

Music is arguably one of the most potent rewards, existing in all cultures as far back as history dates, and currently reported to be among the most pleasurable stimuli by most individuals. In this review, we summarize the literature to investigate how a mere sequence of sound events can become so pleasurable. We examine the role of the brain’s mesolimbic reward and reinforcement circuitry in processing of rewards, and how the connectivity of this system has become more integrated with higher-order brain regions involved in complex thought to give rise to abstract pleasures. We suggest an integrative role for complex cortical processes with long-existing reinforcement circuits and an interaction between sensory processing and decoding mechanisms and affective processing.
Prevalence of Periodontal Diseases in Orlu Local Government Area of Imo State , Nigeria

There has been a global pandemic of periodontal diseases with a rising prevalence worldwide. In Nigeria, reported cases of rising prevalence have occurred because of poor oral hygiene, and other related factors. This descriptive survey study was aimed at ascertaining the prevalence of periodontal diseases in Orlu Local Government Area of Imo state, Nigeria. The main instrument for data collection was a structured interview questionnaire bordering on biodata, economic status, oral hygiene, as well as dental care assessment. A sample of 500 was randomly selected from the population i.e males and females of ages between 6-55yeras (schooling and working population). Data collected was analyzed using descriptive statistics of frequency, percentage, histograms, and pie chart. Results showed that 470(94%) respondents have had one form of periodontal disease while 30(6%) never had it. Also pain and bleeding gums had 34.6% and 19.8% and as such the commonest pattern of periodontal disease in the populace. The disease was commoner amongst 16-25years age group i.e 128(27.2%) and there was also a male preponderance of 59.4% against the female of 40.6%. Sixmonthly dental check-up, and health education were recommended.

Running head : Emotional state classification in PD 1 Optimal set of EEG features for emotional state classification and trajectory visualization in Parkinson s disease

In addition to classic motor signs and symptoms, individuals with Parkinsons disease (PD) are characterized by emotional deficits. Ongoing brain activity can be recorded as electroencephalograph (EEG) to discover the links between emotional states and brain activity. This study utilized machine-learning algorithms to categorize emotional states in PD patients compared with healthy controls (HC) using EEG. Twenty non-demented PD patients and 20 healthy age-, gender-, and education level-matched controls viewed happiness, sadness, fear, anger, surprise, and disgust emotional stimuli while fourteen-channel EEG was being recorded. Multi-modal stimulus (combination of audio and visual) was used to evoke the emotions. To classify the EEG-based emotional states and visualize the changes of emotional states over time, this paper compares four kinds of EEG features for emotional state classification and proposes an approach to track the trajectory of emotion changes with manifold learning. From the experimental results using our EEG data set, we found that (a) bispectrum feature is superior to other three kinds of features, namely power spectrum, wavelet packet and nonlinear dynamical analysis; (b) higher frequency bands (alpha, beta and gamma) play a more important role in emotion activities than lower frequency bands (delta and theta) in both the groups and; (c) the trajectory of emotion changes can be visualized by reducing subject-independent features with manifold learning. This provides a promising way of implementing visualization of patients emotional state in real time and leads to a practical system for noninvasive assessment of the emotional impairments associated with neurological disorders.
Performance of Tungsten wire reservoir cathodes

Research is continuing on development of controlled porosity cathodes capable of very long life times. Tungsten wires are sintered to form a material consisting of a uniform pattern of pores to transport barium from a reservoir. The combination of uniform pores and the reservoir results in very uniform current emission from the surface with extremely long life. The barium diffusion rate can be controlled by the designer.
Analysis on the Relationship between Rating and Economic Growth for the European Union Emergent Economies

This article analyses the relationship between sovereign credit risk rating and gross domestic product for Central and Eastern European Countries for the period 1996 – 2010. In order to study the metioned relationship, we have used a numerical transformation of the risk qualification, thus: we marked 0 the lowest risk; then, we went on ascending, with a pace of 5, up to the score of 355 corresponding to the maximum risk. The used method of analysis is that of econometric modelling with EViews 7.0. programme. This software allows the analysis of data into a pannel type system, involving a mix of periods of time and series of data for different entities. The main conclusion of the work is the one confirming the negative relationship between the sovereign credit risk and the gross domestic product for the Central European and Eastern countries during the reviewed period. Keywords—credit rating agencies, economic growth, gross domestic product, sovereign credit risk rating.
Design and experimental validation of interconnected observers for sensorless induction motor on low frequencies benchmark

The design of two interconnected observers for induction motor drive in sensorless application is adressed in this paper. The first one is dedicated to angular speed and load torque estimation while the second estimates fluxes. Stability of both observers is discussed. Moreover due to the complexity of observation at low frequencies, a part of the contribution of this paper is that the observers are tested and validated on reference trajectories of a sensorless induction motor observer benchmark. This benchmark is applied on an experimental set-up located at IRCCyN (Nantes, France). Robustness experiment tests with respect to parameters variation emphasize the applicability of the designed observers
NeuroImage: Clinical Association between precuneus volume and autobiographical memory impairment in posterior cortical atrophy: Beyond the visual syndrome

Posterior cortical atrophy is a neurodegenerative syndrome characterised by progressive disruption of visual and perceptual processing, associated with atrophy in the parieto-occipital cortex. Current diagnostic criteria describe relative sparing of episodic memory function, but recent ﬁ ndings suggest that anterograde memory is often impaired. Whether these de ﬁ cits extend to remote memory has not been addressed. A large body of evidence suggests that the recollection of an autobiographical event from the remote past coincides with the successful retrieval of visual images. We hypothesised that the profound visual processing de ﬁ cits in posterior cortical atrophy would result in impaired autobiographical memory retrieval. Fourteen posterior cortical atrophy patients, eighteen typical Alzheimer's disease patients and twenty-eight healthy controls completed the Autobiographical Interview. Autobiographical memory in posterior cortical atrophy was characterised by a striking loss of internal, episodic detail relative to controls and to same extent as typical Alzheimer's disease patients, in conjunction with an increase in external details tangential to the memory described. The memory narratives of posterior cortical atrophy patients showed a speci ﬁ c reduction in spatiotemporal and perceptual detail. Voxel-based morphometry analysis revealed atrophy of the parieto-occipital cortices in posterior cortical atrophy but relatively spared hippocampi bilaterally, compared with characteristic atrophy of the medial temporal lobes in typical Alzheimer's disease. Analysis of brain regions showing posterior cortical atrophy-speci ﬁ c atrophy revealed a correlation between perceptual details in autobiographical memory and grey matter density in the right precuneus. This study demonstrates remote memory impairment in posterior cortical atrophy despite relatively preserved medial temporal lobe structures. The results demonstrate, for the ﬁ rst time, profound autobiographical memory impairment in PCA and suggest that this is driven by the well-recognised de ﬁ cits in higher-order visual processing. The ﬁ ndings are discussed in the context of posterior parietal contributions to imagery and memory, and the clinical implications of autobiographical memory impairment for diagnostic and management protocols in posterior cortical atrophy.

DNA sequence variants and risk of perinatal HIV-1 transmission

Background: HLA-G gene is a non-classical MHC class 1 molecule that is highly expressed in the trophoblast at the maternal-fetal interface. In an attempt to elucidate possible immunological mechanisms facilitating protection of infants born to human immunodeficiency virus type (HIV-1) infected mothers, we have been studying genetic variations in the coding and untranslated regions of HLA-G antigen between HIV-1-infected mothers and their infected or uninfected infants. This study investigated whether HLA-G DNA sequence variants are associated with perinatal HIV-1 transmission. Results: Genomic DNA samples were obtained from a nested case-control study of 34 motherchild pairs co-enrolled in a cohort of the Perinatal AIDS Collaborative Transmission Study in New York. The samples were from two groups predominantly of African-American and Hispanic origin: In the first group, both mother and child were HIV-1-infected; in the second group, only the mother was infected while the child remained uninfected. Genotyping of HLA-G gene were performed on the extracted DNA from peripheral blood mononuclear cells using PCR based sequencing and restriction fragment-length polymorphism analyses. Among the studied HLA-G exons, dissimilarities in HLA-G DNA sequence variants between the HIV-1 non-transmitting mother child pairs were mostly observed in exon 8-3'-untranslated region at nucleotide positions T3742A, C3743T, G3777C (P = 0.001). Non-transmitting HIV-1 mother child pairs exhibited dissimilarities at nucleotide position C3743T allele with decreased risk of perinatal HIV-1 transmission, compared with HIV-1 transmitting mother-child pairs carrying this allele (odds ratio 0.02 [95% confidence interval 0.00–0.15] P = 0.00001). In addition, heterozygous dissimilarities at nucleotide positions C634G and 714 insT/G in the 5'-upstream regulatory region were observed between the mother child pairs of the HIV-1-non-transmitting group while homozygous similarities of C634C, and either 714insG/G or mother-child pairs with similar 714insT/G were observed among the transmitting group in the same region. Conclusion: This study identified new variants in the HLA-G gene and provides further evidence that dissimilarities in the HLA-G DNA sequence variants could influence the transmission of HIV1 from infected mothers to their infants.

Scan-based emitter passive localization

This paper investigates the problem of estimating the position of a scanning emitter using a passive scan-based geolocation technique. This is achieved by taking advantage of the geometric constraints introduced by the uniform rotating motion of the antenna main beam as it sweeps across a number of separate receivers. A detailed analysis of the estimation process and accuracy of the emitter position is given and a number of computer simulations showing the benefits of this geolocation technique are also included
