Servo-Position Control with Dynamic Lag Precompensator for Pmsm Drives

The paper presents design of near-time-optimal position control of electrical drive with permanent magnet synchronous motor. The principles of timeoptimal-control and forced dynamic control are combined to form a novel method of achieving a nearly time optimal position control performance in drives equipped with controllers enabling close following of time varying reference position inputs from ‘near time optimal’ model. For compensation of the dynamic lag between model generated position and the real drive position response a precompensator is implemented. The simulations and experimental results show possibility to achieve ‘near time optimal’ behavior of the drive. Index Terms Vector control, Feedback linearisation, Time optimal control, Permanent magnet synchronous motor.
DESIGN AND ANALYSIS OF AN IMPROVED HIGH GAIN NON ISOLATED INTERLEAVED BOOST CONVERTER FOR SOLAR PHOTOVOLTAIC APPLICATIONS

In this paper, a novel non isolated four phase interleaved boost converter (IBC) with high voltage gain and reduced stress has been derived. This converter topology is intended to achieve a high step up gain without applying high duty cycle, utilizing input parallel and output series configuration. With less number of components, switching loss and conduction loss are also much reduced. Uniform current sharing without adding complex control methods reduces input ripple current. Due to reduced current ripple at input side and optimal number of phases, this converter is suitable for photovoltaic interface. The design equations has been derived and analyzed for the proposed converter. The theoretical analysis and simulation results validate the performance of the converter.
Revision of the status of bird species occurring or reported in Colombia 2011 Revisión del estatus de las especies de aves que existen o han sido reportadas en Colombia 2011

following species are added to Colombia's bird checklist: Red-breasted Merganser Mergus serrator (photograph, San Andres & Providencia), Black Scoter Melanitta americana (sight record) and Kelp Gull Larus dominicanus (photographic record). A new subspecies of Common Bush-Tanager Chlorospingus flavopectus olsoni is recognized. Proposed splits are accepted of Oxypogon Helmetcrests into four species (three in Colombia), Lineated Woodcreeper Lepidocolaptes albolineatus into five species (one in Colombia), Curve-billed Scythebill Campylorhamphus procurvoides into three species (one in Colombia), Stipple-throated Antwren Epinecrophylla haematonota into at least three species (one in Colombia) and Sirystes into four species (two in Colombia). The Green-crowned Woodnymph T. fannyi is lumped back into Purple-crowned Woodnymph T. colombica. Dunlin Calidris alpina becomes a confirmed species (photograph) and Caribbean Coot Fulica caribaea is confirmed from mainland records (photograph). A possible vagrant record of Mallard Anas platyrhynchos is presented. Zebra Finch Taeniopygia guttata and Fischer's Lovebird Agapornis fischeri are new escaped species known only from sight records and Java Sparrow Lonchura oryzivora becomes confirmed as an escapee. Several amendments to genus and species names, English names and linear order are made, following recent publications. As a result of these changes, the Colombian checklist again increases in size, for the first time for any country, passing the landmark of 1900 species to 1903 (excluding escapes), of which 1831 are documented by 'confirmed' records on the mainland. The Kelp Gull is Colombia's 1900 th bird.
Analyses of truss structures via total potential optimization implemented with teaching learning based optimization algorithm

According to the well-known principle of mechanics named minimum potential energy, if the total potential energy of a system is minimum, the system is in equilibrium state. Conventional methods use mathematical operations to find minimum potential energy of structures. Alternatively, metaheuristic algorithms that are frequently used for minimization or maximization of an objective function can be employed for this purpose. Thus, Total Potential Optimization using Meta-heuristic Algorithms (TPO/MA) technique has been proposed. In this paper, TPO/MA technique has been presented and used for the analyses of truss structures. The metaheuristic algorithms employed in the present study is teaching learning based optimization (TLBO) method. The named method was tested for three different systems and the results are compared with the documented methods. The proposed method is found to be effective, robust, powerful and accurate for analysing planar and space truss structures. Key-Words: meta-heuristics; teaching learning based optimization; total potential optimization method; truss structures.
Hybrid Vigor

The ecological approach to rationality involves evaluating choice processes instead of choices themselves, and there are good reasons for doing this. Proponents of the ecological approach insist that objective performance criteria (such as monetary gains) replace axiomatic criteria, but this claim is highly contentious. This paper investigates these issues through a case study: 12 risky choice processes are simulated, and their performance records are compared. The first criterion is conformity to the Expected Utility axioms; the Priority Heuristic stands out for frequently violating Transitivity. Next, the Expected Value criterion is applied. Minimax performs especially poorly—despite never violating an axiom—highlighting the tension between axiomatic (coherence) and objective (correspondence) criteria. Finally, I show that axiom violations carry high costs in terms of expected value. Accordingly, coherence does not guarantee objectively high performance, but incoherence does guarantee diminished performance.
Albumin-to-Alkaline Phosphatase Ratio is an Independent Prognostic Indicator in Combined Hepatocellular and Cholangiocarcinoma

Background: The clinical significance of Albumin-to-Alkaline Phosphatase Ratio (AAPR) has been discussed in hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). The aim of this study is to clarify the prognostic value of AAPR in patients with combined hepatocellular and cholangiocarcinoma (cHCC-CCA). Methods: A total of 267 patients pathologically diagnosed as Allen type C cHCC-CCA in our institution were retrospectively enrolled and randomly divided into the training (N=187) cohort and validation (N=80) cohort. The prognostic value of AAPR was evaluated and validated. An AAPR-based nomogram was constructed and its prediction performance was assessed. Results: We identified 0.43 as the optimal threshold value of AAPR by the X-tile software. In the training cohort, the median overall survival (OS) of patients with AAPR < 0.43 was significant shorter than that of those with AAPR ≥ 0.43(15.8 months vs 35 months, respectively, P < 0.001). Univariate and multivariate analyses demonstrated that AAPR was a strong indicator of OS. The concordance index (C-index), receiver operating characteristic (ROC) curves, likelihood ratio tests (LAT), Akaike information criteria (AIC) and decision curve analysis (DCA) demonstrated that AAPR outperformed the Child-Pugh (CP) grade and albumin-bilirubin (ALBI) grade in predicting OS. These findings were further verified in the validation cohort. The AAPR-based nomogram achieved C-index values of 0.76 (95%CI: 0.71-0.81) in the training cohort and 0.69 (95%CI: 0.60-0.78) in the validation cohort, which presented significant superiority to TNM stage. Conclusions: Preoperative AAPR is an independent prognostic predictor in cHCC-CCA. The AAPR-based nomogram contributes to personalized prognosis prediction and clinical decision making for cHCC-CCA.
The Effect of Public Revenue and Public Expenditure in the Realization of Macroeconomic Objectives of Government of Nigeria: Evidence of 2015-2017

The aim of this paper was to examine the effect of public revenue and public expenditure on the actualization of Nigerian macroeconomic objectives within a given period of time. Specifically it examined the extent to which public revenue and expenditure has impacted on inflation rate (price stability), unemployment rate and economic growth in Nigeria within the period of 2015 – 2017. Data were gathered from Nigerian Bureau of Statistics, Central bank of Nigeria statistical bulletin as well as tradingeconomics.com. Content analysis and thematic analysis were employed for the analysis of the study. Findings indicate those macroeconomic objectives of price stability (low inflation target), low unemployment rate as well as stable and increasing economic growth within the period as set by the government were not actualized. Further, there were rising and high inflation rates, rising unemployment rate, slow but unstable economic growth witnessed as well as rising public expenditure and revenue in Nigeria. This situation is contrary to the Keynesian theory as adopted here, who advocates that the use of fiscal policy by government is the way it can achieve its macroeconomic objectives through effective manipulation of both revenue and expenditure. The implication of this is that obviously, the budget of Nigeria and its performance within the period has been ineffective, ill implemented and thus there is need for rethink and reevaluation in other to get a better performance of the budget. Further there is need to ensure that revenue leakages are reduced and prudent expenditure are maintained. This is particularly important given the fact that, there have been consistent budget deficit within the period as such fiscal policy of public expenditure and revenue, if not reexamined; macroeconomic objectives may not be achieved even in the long run.
Light Verb Constructions in Lithuanian: Identification and Classification

Light verb constructions (LVCs) are verb-noun constructions in which the noun carries the semantic meaning and the verb is semantically reduced, when compared with its main meaning, for example, atlikti analize (‘to perform an analysis’). LVCs in Lithuanian have not been addressed much so far. The analysis of Lithuanian LVCs was carried out as a part of the PARSEME project on verbal identification of multiword expressions (MWE). This paper aims at presenting some initial findings on the identification of LVCs in Lithuanian, based on the 1st edition of the PARSEME shared-task results (2017). We describe the identification process according to the semantic and syntactic features of LVCs (PARSEME guidelines 1.0 2017) and discuss the grammatical features of the identified Lithuanian LVCs. LVCs seem to be less frequent in Lithuanian than in other languages: they make up about 0.2% (215 instances) of the analysed 200,000 token corpus. Based on the number of different LVCs, there seem to be two groups of verbs functioning as light verbs: a relatively small group of common light verbs used in the most prototypical examples of Lithuanian LVCs (e.g., vykdyti ‘to perform’, atlikti ‘to perform’, daryti ‘to do’, and turėti ‘to have’) and a larger group of less common light verbs. Most of the nouns in analysed LVCs have suffixes -imas and -ymas, which are the most typical Lithuanian suffixes for deriving a noun from a verb. Almost 40% of all LVCs are used with 1–3 words intervening between a verb and a noun.
Hyperglycaemia in Pregnancy and Anthropometric Parameters in the Offspring at 10 Years: A Community-Based Retrospective Cohort Study in Sri Lanka

Background Studies of developmental origins of health and disease have highlighted the possible role of intrauterine hyperglycaemia, increasing the future risk of obesity, diabetes, and cardiovascular diseases in the offspring. There is limited evidence from South Asian populations for risk estimates for childhood obesity that are attributable to maternal diabetes in utero. Objective The aim of this study was to determine the association between hyperglycaemia in pregnancy (HIP) and anthropometric parameters in the offspring at 10-11 years of age. Methods A community-based retrospective cohort study was conducted in Colombo district, Sri Lanka. In the first stage, children born in 2005 were identified, and the availability of antenatal records was assessed. In the second stage, the exposure status of participants was ascertained based on antenatal records and predefined criteria. In the third stage, height, weight, waist circumference, and triceps skinfold thickness (TSFT) of eligible participants were measured to ascertain the outcome status. Background characteristics were collected by interviewing mothers. A 24-hour dietary recall and a 3-day diet diary were recorded. Results 159 children of mothers with HIP (exposed) and 253 children of mothers with no HIP (nonexposed) participated. Mean ages (SD) of exposed and unexposed groups were 10.9 (0.3) and 10.8 (0.3) years, respectively. The median BMI (17.6 vs 16.1, p < 0.001), waist circumference (63 cm vs 59.3 cm, p < 0.001), and triceps skinfold thickness (13.7 mm vs 11.2 mm, p < 0.001) were significantly higher in the exposed group. Offspring of women with HIP were more likely to be overweight (aOR = 2.6, 95% CI 1.4–4.9) and have abdominal obesity (aOR = 2.7, 95% CI 1.1–6.5) and high TSFT (aOR = 2.2, 95% CI 1.06–4.7) at 10-11 years than children who were not exposed after adjusting for maternal BMI, maternal age at delivery, and birth order. Conclusions Intrauterine exposure to HIP is a significant determinant of overweight, high TSFT, and abdominal obesity in the offspring.
What Does It Mean to Take Diversity Seriously? On Open-Mindedness as a Civic Virtue

Taking diversity seriously should mean building political institutions that are open to diversity, rather than closed to it, and cultivating civic virtues that are welcoming of diversity, rather than hostile to it. Open-mindedness, in particular to the views of one’s political opponents, would seem to be such a civic virtue. This essay argues that this disposition cannot be properly cultivated in an institutional context—electoral or party democracy—which thrives on and encourages the exact opposite virtue: partisanship. The essay gestures instead towards a non-electoral form of democracy that would structurally encourage open rather than closed-mindedness and thus fully harness the benefits of diversity.
Enhanced Face Recognition Approach under Illumination Variations Based on Local Binary Pattern

— A new face recognition algorithm proposed by Z.Lian, M.J.Er and J.Li is implemented in this research paper. Unlike the other face recognition schemes, the proposed algorithm works efficiently in varying Illumination conditions. This paper highlights the limitation of present face recognition algorithms. Algorithms offering efficient feature extraction methods fail to differentiate between similar images under varying light conditions. Algorithms with efficient preprocessing methods give a lot of errors during distance computation. Distance measurement such as Histogram Intersection works well at global level but fails to compute pixel distance effectively. Similarly hamming distance gives better approximation of pixel distance but performs poorly at global level. A solution to the highlighted problems is presented in terms of new proposed algorithm by Z.Lian, M.J.Er and J.Li. The new algorithm is explained with the help of block diagram and experimental results. A detailed testing is done on Yale B & Extended Yale B data sets and further comparison with other existing schemes is also included to highlight the advantages of proposed method.
THE IMPACTS OF IC BUSINESS STRATEGY TOWARDS COMPANY PERFORMANCE: THE CASE OF MALAYSIAN PUBLIC LISTED COMPANIES

The 21st Century demands new business paradigms and every business will need help shifting from a focus on tangibles to intangibles or IC (IC) to become a “smarter company”. Thus, many companies are embarking on different approaches or strategies to be more competitive and create greater values. As such, strategy-related studies in IC are concerned with the management of IC to enhance performance. Earlier researchers suggest that companies which adopt IC strategies are able to achieve competitive success compared to companies that based their strategies on physical and financial resources. Studies on business strategy had focused on the strategy-performance relationship with most being strongly influenced by the frameworks developed by Miles and Snow (1978) and Porter (1980). The objective of this study is to find out whether business strategy adopted by the Malaysian Public-listed Companies (PLCs) has significant impact of business performance as far as IC is concern. Prior to that, IC is converted into IC Index based on the 178 managers’ responses to questionnaire survey about the IC practices in the Malaysian PLCs. Performance measurement employed in this study is based on the company’s Return on Equity (ROE) and Earnings per Share (EPS). Business strategy is based on Miles and Snow as well as Porter’s. Results from the multiple regression models prove that IC Index and Business Strategy are significant predictors for all selected performance measures. This study is expected to make a contribution to the companies by demonstrating that better IC management practices and right strategy implementation may contribute a better impact on business performance.
INVESTIGATION OF SUBSYNCHRONOUS OSCILLATIONS IN GRID CONNECTED TYPE-2 WIND FARM AND ITS MITIGATION USING STATCOM

This paper explores the possibility of occurrence of subsynchronous resonance (SSR) in a system comprising a conventional induction generator-based Type-2 wind farm connected to a series-compensated line. The induction generator is equipped with rotor resistance controller (RRC) which cuts in when wind velocity exceeds the rated. A comprehensive small-signal model of the system that includes the controller is developed and used for the analysis. The subsynchronous oscillations considered are due to self-excitation, torsional interaction and transient torque amplification. The test system considered is IEEE first benchmark model (FBM) for subsynchronous resonance with synchronous generator replaced by aggregated wind farm. Eigenvalue analysis is employed to evaluate system-wind farm interaction. The analysis includes the impact of series compensation level, wind velocity and wind farm size on SSR. Eigenvalue analysis is validated electromagnetic transient simulations and fast Fourier transform (FFT) analysis. The contributions of this paper are: Type-2 wind farms are more susceptible to selfexcited oscillation at normal (practical) compensation levels, mitigation of these self-excited oscillations by the STATCOM controller that is employed at the point of common coupling for reactive power compensation, thereby avoiding the necessity of other controllers (FACTS).
Eye Blink to Voice for Paralyzed Patients

Prior, the deadened patients couldn't communicate and decipher thus the connection with the outside world happens over human-PC cooperation; for example, following eye developments and checking cerebrum waves. By and by, individuals are badly arranged to utilize mind development observing gadgets on the grounds that the clients must wear it. Our venture is shrewd framework which is exceptionally intended for MND patients. The patients can't speak with the consideration suppliers on the off chance that he/she is experiencing MND sickness over the bed. In this examination investigation, a component supports to demand others since it is both basic just as laid-back method that plans to help MND victims. This examination study gives an assistive gadget to distinctively abled patients predominantly incapacitated patients. Everybody realizes that deadened patients can't speak with the outside world, so this framework gives a help to them to speak with their own eye squint and get their prerequisites satisfied via overseers. Likewise gives an effective and exact outcome when contrasted with the current ones. Both of the guardian not being available or the patient necessity isn't satisfied a message will be sent to his relatives alongside the patient’s prerequisite required. The business can utilize this investigation for secret word validation utilizing virtual keypad where dependent on the flickers comparing to the specific component in the virtual keypad individually. Our investigation focuses to produce an ongoing video preparing strategy, which identifies the eye squint absolutely independent of the head directions, day or night. In light of the flicker relating to the prerequisite by the patient is identified and it is coverted to voice and given as a yield. Aside from this, a message alarming framework is additionally made so the overseers and the relatives will become more acquainted with about the patient’s prerequisites.
Equity Incentives, Executive Compensation, and Real Activity Management: Panel Data Evidence from Quoted Nigerian Firms

The main inspiration for the present research study is to empirically investigate equity incentives and executive compensation and how they affect real activity management in quoted industrial goods firms in Nigeria. The dependent variable that is real activity management was determined using Roychowdhury models, while the independent variables were proxied by executive stockholdings, bonuses, and fixed salaries. Cross-sectional data were sourced from the audited financial statements of the firms. The Ordinary Least Square (OLS) method of co-integration, unit root, and Granger causality tests were used to determine the extent to which equity incentives and executive compensation affect real activity management. After cross-examination of the validity of the pooled effect, fixed effect, and random effect, the study accepts the random effect model. Model two found that the independent variables explain only 6.9 percent variations on the real activity management. The beta coefficient found that executive stockholdings, bonuses, and fixed salaries have a positive effect on real activity management. The study concludes that equity incentives and executive compensation do not have any significant effect on real activity management of quoted industrial goods firms in Nigeria. From the findings we recommend that the policymakers need to provide adequate regulation on the determination of equity incentives of the directors of listed companies; this will reduce the negative effect of ownership concentration for directors and the overbearing influence of directors in annual general meetings.
Physiological Changes Associated with Performance of Kentucky Bluegrass Cultivars during Summer Stress

Understanding the factors influencing the performance of Kentucky bluegrass (Poa pratensis L.) cultivars under summer stress is necessary for developing criteria for identifying resistant germplasm. The objectives of this study were to evaluate two Kentucky bluegrass cultivars for leaf water (ψ 1 ) and osmotic potential (ψ π ), stomatal resistance (R s ), leaf: air temperature differential (ΔT) and determine the relationship of these parameters to drought and heat tolerance. Stress-resistant ('Midnight') and susceptible ('Nugget') cultivars were evaluated in a field study during 1993 and 1994 under moisture-limiting conditions. Leaf water potential for 'Nugget' was higher than for 'Midnight' in 1993 and similar in 1994. 'Midnight' had lower ψ π than 'Nugget' during the evaluation period in 1994. 'Midnight' maintained more open stomata (lower R s ) and lower AT than 'Nugget' at the end of the dry down period when 'Nugget' was showing visual signs of stress. 'Midnight' and 'Nugget' had similar root weight at the 0- to 45-cm depth zone in 1994. Lower basal osmotic potential (i.e., higher solute concentration) may be the physiological mechanism allowing larger stomatal aperture in 'Midnight'. Greater transpirational cooling in 'Midnight' relative to 'Nugget' was correlated with higher turf quality for 'Midnight'.
