A HYBRID APPROACHES FOR THE PROFIT BASED UNIT COMMITMENT PROBLEM IN THE DEREGULATED MARKETS

In this paper, two hybrid models between Lagrange Relaxation (LR) with Evolutionary Programm ing (EP) and Lagrange Relaxation (LR) with particle swa rm optimization (PSO) are used to solve the profit bas ed unit commitment problem in a deregulated electricity mar ket. In recent days, operation and control of generating un it is modified because of the revolution in power system structure. Energy price becomes an important parame ter to make a decision in this restructured system. Unit commitment (UC) in such a competitive environment i s ot the same as the traditional one. The objective of U C is not only to minimize production cost as before but also to find the solution that produces a maximum profit for gen eration company (GENCO). A modest attempt has been made in this paper presents a simulated case study for the profi t based unit commitment problem and demonstrates the effectiveness of the proposed approaches.
Modeling, Simulation and Practical Realization of the Spiral Inductors Used in Wireless Power Systems

With the increase of the number of devices powered and using wireless systems, the optimal design of such systems is necessary. The present study aims at determining the influence of parameters like distance between inductors and the placement of ferrite layers on the phenomena regarding the spiral inductors through their numerical modelling. A simple wireless power system constructed from an emitter and a receiver spiral inductor is considered in the present study. The numerical modelling of the system is made using the software program Ansys Maxwell 3D Field Simulator. Also, a comparison of the results obtained from the modelling and simulation of this wireless power system and from a practical model made in the laboratory is presented. As the modelled structure, the practical model is constructed from two spiral inductors. The importance of numerical modelling of the structure in order to determine an optimum is highlighted. The parameters obtained and analysed from the 3D model are magnetic field intensity, magnetic induction and mutual inductance, while for the constructed model the voltage is studied. For the modelled structure, the distance between the receiver and the emitter is varied between 0.05 mm and 5 mm, considering the structures with and without the ferrite layers in order to reach a conclusion.

Democracy and Corruption: A Longitudinal Study of Latin America

Although often unable to satisfactorily solve the problem, democracy (especially enduring democracy) is commonly believed to reduce corruption. Yet, both Transparency International and World Bank continue to attach a high risk of corruption to Latin American countries: corruption and impunity remain prevalent in the area, despite consolidating democratic regimes and recent anticorruption reforms. Using level of democracy and its duration, as well as some information on the perception of corruption obtained from the Latinobarometro, we analyzed a panel data covering the period 2005-2009 in 18 Latin American countries. Our main results show that democratic levels have no clear impact on corruption, while democratic history does, but only after a certain period. Citizens’ trust towards government is also strongly associated to corruption levels: in particular, whenever citizens perceive government and the public administration to be inefficient and arbitrary, their perception of gains against corruption significantly decreases.
Fine structure of the cortex in the lichen family Parmeliaceae viewed with the scanning-electron microscope

Hale, Mason E. , Jr. Fine Structure of the Cortex in the Lichen Family Parmeliaceae Viewed with the Scanning-electron Microscope. Smithsonian Contributions to Botany, number 10, 92 pages, 150 figures, 1971. -The scanning-electron microscope was used to examine the cortical surface of 123 species of lichens in 12 genera of the lichen family Parmelinceae. Two general types of cortex were found, one consisting of exposed hyphae and one with the hyphae covered by a thin polysaccharide epicortex. The epicorticate species fell into two groups, one with a tightly appressed continuous epicortex and one with a more loosely associated pored epicortex. Type of epicortex is a constant character a t the genus and section level and appears to have considerable usefulness in the taxonomy of the family.

Motor Imagery with Brain-Computer Interface Neurotechnology

A brain-computer interface (BCI) analyzes brain activity in real-time to convey information or control an external device. BCI systems often consist of a biosignal amplifier for EEG data acquisition, parameter estimation, and classification to make decisions in real-time. Many BCIs are controlled via motor imagery (through imagined movements), which modulates the EEG in certain frequency bands and regions. Motor imagery based BCIs are used for various applications like cursor control,
Recruitment and growth of herb-layer species with different colonizing capacities in ancient and recent forests

Forest herbs differ greatly in their capacity to recolonize secondary forests established on former agricul- tural land. We investigated whether interspecific differences in recruitment or growth can account for differences in coloni- zation success. Seeds and adults of two species with limited colonization capacities (Anemone nemorosa and Primula elatior) and two species with high colonization capacities (Ranunculus ficaria and Geum urbanum) were introduced in ancient and recent forest sites within the Muizen forest (Bel- gium). At all sites, half of the plots were also cleared of above- ground vegetation. Seedling establishment was similar in recent and ancient forest sites. However, both the number and subsequent sur- vival of seedlings of the two hemicryptophytes (G. urbanum and P. elatior) were significantly lower when vegetation cover was present, while seedling number and survival of the two geophytes (A. nemorosa and R. ficaria) were less influenced by vegetation cover. Adult performance of P. elatior and G. urbanum was significantly better in the nutrient enriched recent forest stands and in the absence of vegetation cover. Performance of A. nemorosa and R. ficaria was not affected by any of these factors. We conclude that the extent of seed limitation is probably the main cause for the different coloni- zation capacities of the species investigated.
Effect of Type of Substrate, Ions and Aeration on Photo-catalytic Oxidation of Phenol

The effect of different parameters on photo-catalytic oxidation of phenol was studied. Photo-catalytic oxidation of phenol in various substrates groundwater, miliq water &evian water was studied. Rate of the reaction in various experimented substrate was found to be in the following order: Milliq> Evian Water> Groundwater, presence of ions in the substrate decided the rate of the reaction. Effect of various ionscalcium, magnesium, carbonate, chloride and bi-carbonate, which were abundantly found in water, was studied. Cations – magnesium and calcium had no effect on the rate of reaction, whereas anions had detrimental effect on the rate of reaction. Aeration of solution had positive effect on the rate of reaction.
Quantification of Ulocladium atrum in necrotic plant tissues by monoclonal antibody-based enzyme-linked immunosorbent assay

Five murine hybridoma cell lines secreting monoclonal antibodies (MAbs) with similar binding specificities were raised to extracts from cyclamen leaves colonized with Ulocladium atrum, a saprotrophic fungus used for biological control of Botrytis cinerea. One of the cell lines produced a MAb, UA-PC3, which was used to develop a quantitative ELISA to deternnine the biomass of U. atrum in extracts from colonized leaves. The antigen, which is water soluble, was present on the surface of conidia and hyphae and was secreted into culture fluids. Production of the antigen was much greater in vivo than in vitro. Germination of conidia took place in saline buffers at 4 °C after 6 h. To avoid amplification of the antigen in biomass assays of the fungus in extracts from sporulating tissues, coating of microtitre wells in ELISA was reduced to 1 h.
Effect of Outsourcing Supporting Activities on the Financial Performance of Hotel Industry in Nigeria (2009- 2018)

The study examined the effect of outsourcing supporting activities on the financial performance of Hotel industry in Nigeria. Specific objectives of the study are; determine whether outsourcing of transportation services affect the financial performance of Hotel industry in Nigeria; assess whether outsourcing of advertising services affect financial performance of Hotel industry in Nigeria; find out whether outsourcing of legal services affects organization financial performance of Hotel industry in Nigeria and establish whether outsourcing of technology services affects organization financial performance of Hotel industry in Nigeria. Ex post facto research design was adopted for the study. The population of this study covered the three listed hotels on the Nigerian Stock Exchange. Data were collected from annual accounts of these three hotels and the four formulated hypotheses were tested using regression analysis and Pearson coefficient correlation with aid of SPSS version 20.0. The study revealed that outsourcing of transportation services has negative significant effects on the financial performance of Hotel industry in Nigeria. Also outsourcing of advertising services has positive significant effect on the financial performance of Hotel industry in Nigeria.

Survival of Timber Rattlesnakes (Crotalus Horridus) Estimated by Capture–recapture Models in Relation to Age, Sex, Color Morph, Time, and Birthplace

Abstract Juvenile survival is one of the least known elements of the life history of many species, in particular snakes. We conducted a mark–recapture study of Crotalus horridus from 1978–2002 in northeastern New York near the northern limits of the species' range. We marked 588 neonates and estimated annual age-, sex-, and morph-specific recapture and survival rates using the Cormack-Jolly-Seber (CJS) model. Wild-caught neonates (field-born, n = 407) and neonates produced by captive-held gravid females (lab-born, n = 181) allowed comparison of the birthplace, or lab treatment effect, in estimated survival. Recapture rates declined from about 10–20% over time while increasing from young to older age classes. Estimated survival rates (S ± 1 SE) in the first year were significantly higher among field-born (black morph: S = 0.773 ± 0.203; yellow morph: S = 0.531 ± 0.104) than among lab-born snakes (black morph: S = 0.411 ± 0.131; yellow morph: S = 0.301 ± 0.081). Lower birth weights combined with a lack of field exposure until release apparently contributed to the lower survival rate of lab-born snakes. Subsequent survival estimates for 2–4-yr-old snakes were S = 0.845 ± 0.084 for the black morph and S = 0.999 (SE not available) for the yellow morph, and for ≥5-yr-old snakes S = 0.958 ± 0.039 (black morph) and S = 0.822 ± 0.034 (yellow morph). The most parsimonious model overall contained an independent time trend for survival of each age, morph, and lab-treatment group. For snakes of the first two age groups (ages 1 yr and 2–4 yr), survival tended to decline over the years for both morphs, while for adult snakes (5 yr and older), survival was constant or even slightly increased. Our data on survival and recapture are among the first rigorous estimates of these parameters in a rattlesnake and among the few yet available for any viperid snake. These data are useful for analyses of the life-history strategy, population dynamics, and conservation of this long-lived snake.
Split Gibbs Sampling Algorithm for Consistent Motif Discovery

Motif discovery is a widely studied problem in bioinformatics, used to discover common patterns across divergent biological sequences. Gibbs sampling is commonly used to perform motif discovery. However Gibbs sampling is often susceptible to local maxima issues, meaning that the algorithm may sometimes fail to converge on discovery of the most optimal motif in a group of biological sequences. The present study shows how by running Gibbs sampling in batches of sequences and averaging out the results of each batch, consistent motifs can be discovered across separate, independent executions of the algorithm. This method was shown to be effective, regardless of motif size.
Automatic Disease Inference System on the basis of Health Related Questions via Deep Learning

: Better health is central to human happiness and well being. But diseases are one of the increasing subject. The health seeker have many online and offline methods to get the information requested by them. The researchers are encouraged by the advancement in computer technology and machine learning techniques are used to develop software to assist doctors in making decision without necessitating the direct consultation with the specialists. Automatic disease inference is significance to overcome the difficulty of online health seeker.

Then user will search for their needs as query. Next preprocesses the query to find the medical attributes. Then the preprocessed attributes to identify the corresponding disease concept.
Eigenvalue Analysis for Stability Improvement of Wind Turbine by Using UPQC Based on Fuzzy Controller

Abstract — the unified power quality conditioner (UPQC) can be utilized to alleviate the fluctuations and improve the stability of the wind turbine. The fuzzy controller is able to handle non-linear and time varying systems. This paper presents application of the fuzzy controller in control system of the UPQC for stability enhancement of wind farm. A frequency-domain method based on a linearized system model using root locus, eigenvalue technique and a time-domain analysis based on nonlinear system model are both employed to verify the effectiveness of the proposed controller. It is validates the UPQC with proposed controller can enhance the stability margin in tested power system significantly and it has fast response. The proposed controller is robust and powerful for recovery of the bus voltage rather than UPQC with classic controller.
A Study of Organizational Commitment of Manufacturing Workers in Singapore

This exploratory study discusses the three components of the Allen-Mayer's framework of organizational commitment, namely the affective, continuance and normative aspects. It reports the behavioral outcomes of a pilot study and investigates the relationship between two instruments measuring affective commitment, the Organizational Commitment Questionnaire (OCQ) and the Affective Commitment Scale (ACS). The results indicate the unidimensionality of the OCQ and suggest that the ACS may not be as homogeneous as it is commonly assumed.
Cogging torque and torque ripple analysis of permanent magnet flux-switching machine having two stators

The analysis of cogging torque, torque ripple and total harmonic distortion of a permanent magnet (PM) flux-switching machine having separate excitation stators is presented in this study. Further, the effect of unbalanced magnetic force (UMF) on the rotor of this machine is also investigated. A comparison of the analysed machine having different rotor pole configurations is also given. The analysis shows that the largest cogging torque, torque ripple as well as total harmonic distortion (THD) are obtained in the four-rotor-pole machine while the least of THD and torque ripple effects is seen in the thirteen-rotor-pole machine. Furthermore, the evaluation of the radial magnetic force of the machines having an odd number of rotor poles shows that the investigated machine having a five-rotor-pole number exhibits the highest value of UMF, while the smallest amount of UMF is obtained in an eleven-rotor-pole machine. Similarly, it is observed that the machines having an even number of rotor poles exhibit a negligible amount of UMF compared to the ones of the odd number of rotor poles.
Relative Orbit Determination for Formation Flight Based on Unscented Transformation

This paper discusses the relative orbit determination of formation flying spacecraft based on spacecraft-to-spacecraft range measurements. The major challenge of this problem is that, since the available initial guess of estimation and the dynamic range of the relative orbital motion itself are of the same order, relatively higher convergence capability is required for the estimator to realize an accurate guess. The Bayesian filter, which is generally applied to this kind problem, is, however, found to have an insufficient convergence performance. This paper derives a new batch sequential estimator utilizing "Unscented Transformation. " Since this method can directly deal with nonlinear system equations, a higher convergence capability can be obtained starting from poorer initial guesses.

A Novel High Frequency Isolated Full-Bridge Three-Level AC/AC Converter

In order to solve the problems existed in the field of high power applications such as voltage stresses and harmonic interferences of the two-level AC/AC converter. A new kind of high frequency isolated full-bridge three-level AC/AC direct converter is proposed. The converter has many advantages such as two-stage power conversions, simple topology and, low voltage stresses. The topology of circuit, operational principle and six kinds of operational strategy are deeply analyzed. The control method of SPWM, which is based on instantaneous voltage value feedback, is used to respond fast to the change of input and output voltage. The control method of converter driving signal, which is from the comparing of four carrier waves and error magnification signal, is summarized. The circuit is simulated by saber and the result indicates that the wave of the converter is improved; however the harmonic and voltage stresses are reduced. 

Vertical Structure of Heterotrophic Bacterioplankton Communities in the Western Pacific Ocean

The abundance and composition of summer heterotrophic bacterioplankton communities at the Western Pacific Ocean (WPO) were determined using catalyzed-reporter depositionfluorescence in situ hybridization (CARD-FISH) technique. Several oligonucleotide probes specific to the Domain Bacteria (EUB338), Phylum Proteobacteria (α-, β-, and γ-Proteobacteria and SAR 11); Actinobacteria (HGC); and Cytophaga-Flavobacter-Bacteroides (CFB) were used to identify and quantify the common bacterial phyla relative to total microbial abundance using 4’ 6-diamidino-2-phenylindole (DAPI) over a depth profile – from 10 to 4000 m. The profiles of microbial and bacterial abundance, temperature, and oxygen all decreased with depth, in contrast to the profiles of the inorganic compounds. Around 30–59% of the DAPIpositive cells took up the EUB338 probe, suggesting that bacteria are numerically significant components of the microbial biomass in the WPO. Phylum Proteobacteria was the predominant group in the whole water column, with classes α-and γ-Proteobacteria and SAR 11 numerically dominating at specific depths. Statistical analyses showed an association between the bacterial groups – α-Proteobacteria and CFB – and the environmental parameters – temperature and chlorophyll-a concentration – at the depth of 100 m, suggesting the role of organic matter and temperature in structuring the bacterial community in this oceanic regime. This study provided a preview on the abundance and controls of specific groups of heterotrophic bacteria in the WPO, warranting a more detailed and comprehensive investigation of the community structure at clade or genus level.
