A REAL TIME EMULATOR OF VARIABLE PITCH WIND TURBINES USING TORQUE-CONTROLLED INDUCTION MOTORS

Owing to the technical difficulties of experimental investigations of real wind turbines, Wind Turbine Emulator (WTE) plays a role for performing such experimental tasks. This facilitates to conduct advanced research efforts for wind energy conversion system applications without reliance on natural wind resources. In this paper, a WTE (able to emulate the steady-state and dynamic wind turbine behavior) is experimentally developed. This represents a chance to validate not only the behavior of the proposed controllers, but also to extensively evaluate the properness of their developed dynamic models as well. For this aim, a motor generator set based two induction motors and Digital Signal Possessing (DSP) board were used to develop the WTE in order to simulate the aerodynamic characteristics of fixed speed-variable pitch wind turbine. The response of the proposed WTE during wind speed variations and the behavior of its related pitch controller are tested and recorded. All presented test results corroborated the efficacy of the developed WTE for profiling the dynamic behavior of variable pitch turbines for analyzing wind farm applications.

Despite the interest in (anti-)perovskites and diverse hydrides as hydride conductors and all-solid-state battery materials, little experimental evidence on anion diffusion in these compounds is available. Herein, we use neutron diffraction at high temperatures to discover pathways and estimate activation barriers of anion migration in mechanosynthesized powders of BaLiF3, BaLiH3, and BaLiD3. We critically assess the limitations of both current methods for deriving effective one-particle potentials (i.e., via modelling of the probability-density func-
Determination of Synthetic Dyes in Various Food Samples of Iran’s Market and their Risk Assessment of Daily Intake

THE AIM of this study was to measure the level of synthetic food dyes used in different foodstuffs of Iran’s markets via ion-pair high-performance liquid chromatography diode array detector (Ion-Pair HPLC-DAD). The chronic daily intake (CDI), target hazard quotient (THQ) and hazard index (HI) of synthetic dyes for Iranian population were calculated. Based on obtained results, from 74 foodstuff samples tested, only five synthetic dyes (Quinoline, Sunset yellow, Carmoisine, Allura Red and Brilliant Blue) were detected. Sunset yellow was the most commonly used synthetic colorant (45%). The highest concentration of synthetic colors were identified in fruit snacks (361 mgkg-1) followed by jelly product (161.9 mgkg-1), jelly powder (125.5 mgkg-1), ice products (104 mgL-1) and drinks (99.8 mgL-1). To the determine risk of exposure of Iranian consumers to five identified colors in all food product samples the CDI and THQ values were respectively lower than acceptable daily intake (ADI) recommended by WHO/FAO and one. Also, the HI values of all identified colors were lower than one, that did not represent a sever public health risk for synthetic color intake through assessed food samples in Iran’s market. Nevertheless, the results highlight the importance of a more attention monitoring of these dyes by the public and food health authorities Iran.
Modelling Distributed Systems in Distributed Autonomous and Asynchronous Automata (DA3)

Integrated Model of Distributed Systems is used for modeling and verification. In formalism, the distributed system is modeled as a collection of server states and agent messages. The evolution of the system takes the form of actions that transform the global system configuration (states and messages) into a new configuration. Formalism is used in the Dedan verification environment for finding different kinds of deadlocks: communication deadlocks in the server view and resource deadlocks in the agent view. For other purposes, a conversion has been developed to equivalent models: to Petri nets for structural analysis and do Distributed Autonomous and Asynchronous Automata (DA3) for easy graphical modeling in terms of system components. In addition, it is possible to simulate a verified system on distributed components in DA3. The automata have two forms: Server-DA3 (S-DA3) for the server view and Agent-DA3 (A-DA3) for the agent view. DA3 formalism is compared to other concepts of distributed automata known from the literature.

The Impact Of Nigeria’s Democratic Leadership On Educational Policies And Values: A Case For Sustainable National Development

Education is a foremost plank for assessing the effectiveness of government. Since Nigeria’s return to democracy in 1999, the education sector has witnessed a good number of developments, positive and negative. While admittedly, the educational policies of the democratic governments have not been shown to be radically different from what obtained in the military era, there are noticeable changes in many integral components of education policy attributable to the democratic phenomenon including funding, value system, access, job opportunity, and the passage of very important legislations. The paper discusses the impact democratic governance in Nigeria has had on education policy in the specific areas highlighted. A lot has been accomplished in the current dispensation but only a few pass the sustainability test. The paper identified ‘short-termism’ as a major drawback to democratic governance which combines with poor investment in education to hold back qualitative education in Nigeria. The paper concludes that the way forward is to address these challenges head-on. Keywords—Impact, Nigeria, Democratic, Policies, Leadership, Educational, Values, Sustainable, National and Development.

Random fields and central limit theorem in some generalized Hölder spaces

Abstract. For rather general moduli of smoothness ρ (like e.g. ρ(h) = h ln(c/h) ) the Hölder spaces Hρ([0, 1] ), are characterized by the rate of coefficients in the skew pyramidal basis. With this analytical tool, we study in terms of second differences the existence of a version in Hρ for a given random field. In the same spirit, central limit theorems are obtained both for i.i. d. and martingale differences sequences of random elements in Hρ.
Nonlinear transient heat transfer analysis using two integration methods with different distribution of integration points in the domain in a meshless formulation

In this article, the transient heat transfer problem with both convection and radiation boundary conditions is studied. The meshless radial point interpolation method is implemented in this numerical study. Also, two integration methods, the Cartesian transformation method and the Gaussian quadrature method which uses background cells, are employed for computation of the domain integral. First a homogenous medium with both convection and radiation boundary conditions is considered. The temperature distribution obtained by the proposed meshless method, is compared with the analytical solution for a heat transfer problem and excellent agreement is observed. Then, a number of example problems in a layered composite and a functionally graded sample with both convection and radiation boundary conditions are solved and the temperature results are compared with those of ABAQUS software. Through the numerical examples it is observed that using the Cartesian transformation method in comparison with the background cell method in convection boundary conditions reduces the error to half and in radiation boundary conditions reduces the error to one-quarter. This numerical method is a meshless method which does not require any background mesh. Moreover, the amount of error using the background cell method in problems with radiation boundary conditions is more than those with convection boundary conditions. This shows the advantage of using Cartesian transformation method in problems with radiation boundary condition which have a higher degree of nonlinearity, due to the temperature dependent boundary conditions.
Short communication PREVALENCE AND PATHOLOGICAL LESIONS OF ONCHOCERCOSIS (ONCHOCERCA FASCIATA) IN CAMELS (CAMELUS DROMEDARIUS)

The filarial nematode Onchocerca fasciata lives as an adult worm, forming well developed fibrous tissue nodules within the fascial sheath of various parts of the camel body. This study was conducted to identify the prevalence and pathology of camel onchocercosis. A total of 298 dromedary camels of both sexes and different ages were examined carefully before and at the time of slaughtering. Twenty nine out of 298 camels (9.73%) were infected with O. fasciata. Nineteen out of 156 females (12.17%) and ten out of 142 males (7.04%) were positive. Grossly, one or multiple nodules with 1 to 2.5 centimeters in diameter were observed. The nodules were dry and raised, tactile or hard in their texture. On cross section, tangled masses of thin filarial worms were surrounded by a thick whitish fibrous connective tissue. Maximum number of nodular lesions was found in subcutaneous tissues of the neck, abdomen, hind limbs and other parts of infected camels. The intensity of infection, varied between one nodule and 18 nodules. Histopathologically, multifocal granulomatous inflammatory reactions were observed to be associated with the parasites in the affected areas. Transverse and longitudinal cross sections or fragment of the worms with different degrees of surrounding inflammatory reaction were scattered inside the granulomas.

CONSTRUCTAL DESIGN APPLIED TO A FINNED CHANNEL UNDER FORCED CONVECTION FLOWS WITH DIFFERENT IMPOSED PRESSURE DROPS

This paper aims to numerically study the heat transfer in a two dimensional finned channel under laminar, incompressible and forced convective flow with adiabatic walls. The main purpose is to maximize the convection heat transfer by changing the fin’s dimensions by means of Constructal Design. Numerical computations are performed for different Bejan numbers ranging from 0.182 up to 18.2. For all simulations the Prandlt number is kept constant, Pr = 0.71. The fluid motion throughout the channel is caused by imposition of pressure difference between inlet/outlet surfaces. Concerning heat transfer, it is caused by the difference of temperature between the inlet stream of fluid and the heated fins placed at the channel surfaces. The first fin is positioned in the lower surface of the channel while the second one is placed in the upper one. The problem is submitted to three constraints, the channel area (H × L), area of two fins and occupancy areas for the fins. It is considered here that both fins have the same fraction area (ratio between the fins and occupancy areas)  = 0.2. The problem is submitted to three degrees of freedom: H/L (ratio between height and length of channel), H3/L3 and H4/L4 which represent the ratio between the height and length of the first and second fin, respectively. Here, the second fin remains unchanged, being its dimensions H4/L4 = 2.0, whereas the first one is free to modify its dimensions, H3/L3. The channel dimensions are also constant. The solutions are sought using the conservation equations of mass, momentum and energy being these ones discretized through the Finite Volume Method (FVM). Results showed the importance of Constructal Design application for thermal improvement of the problem. Thermal efficiency differences of 5 times where achieved when comparing the best and worst cases. Other important observation is concerned with the effect of ratio H3/L3 over heat transfer ratio (q) which varied significantly from a case where a pressure drop is imposed in the channel to other case where the driven force is caused by imposition of velocity field at the channel inlet.
Metal Contents and Acute Toxicity of Combined Vernonia amygdalina Leaves and Garcinia kola Seeds-VAGK, a Herbal and Nutritional Formulation in Male Wistar Rats

While plants have been useful to man as food and medicine, many have the potentials to induce toxicity either singly or in combination, which may result from their phytochemical contents or accumulation of toxic metals. Therefore, this study investigated the metal contents and acute toxicity of Vernonia amygdalina (VA) leaves and Garcinia kola (GK) seeds in single and combined forms on rat′s kidney and liver. Aqueous extracts of these plants were used to investigate their acute toxicity potentials separately and in combined formulation, VAGK, using male Wistar rats. Following previous studies, a limit acute toxicity investigation of VA and GK were carried out. In addition, a full acute toxicity test was performed on VAGK using Lorkes’ method. The geometric means of doses were used to obtain the acute toxicity value. Histopathological examination was carried out on harvested rats’ kidney and liver while metal analysis was performed on the powdered plants. Results showed that all animals survived the limit dose as well as the full acute toxicity tests. The Kidney and liver revealed no notable pathological changes in the tested plants. Concentration of some of the analysed metals (mg/kg) in plants fell within recommended permissible limits except for Pb, Co, Cr and Ni, which were above these limits. In conclusion, although the acute oral toxicity test revealed no mortality and demonstrated no detrimental effects on the kidney and liver of the treated rats, however based on metal results, caution must be taken when using these plants as herbal remedy.
Good Semi-supervised VAE Requires Tighter Evidence Lower Bound

Semi-supervised learning approaches based on generative models have now encountered 3 challenges: (1) The two-stage training strategy is not robust. (2) Good semi-supervised learning results and good generative performance can not be obtained at the same time. (3) Even at the expense of sacrificing generative performance, the semi-supervised classification results are still not satisfactory. To address these problems, we propose One-stage Semi-suPervised Optimal Transport VAE (OSPOT-VAE), a one-stage deep generative model that theoretically unifies the generation and classification loss in one ELBO framework and achieves a tighter ELBO by applying the optimal transport scheme to the distribution of latent variables. We show that with tighter ELBO, our OSPOT-VAE surpasses the best semi-supervised generative models by a large margin across many benchmark datasets. For example, we reduce the error rate from 14.41% to 6.11% on Cifar-10 with 4k labels and achieve state-of-the-art performance with 25.30% on Cifar-100 with 10k labels. We also demonstrate that good generative models and semi-supervised results can be achieved simultaneously by OSPOT-VAE.
A Method of Directly Defining the inverse Mapping (MDDiM) for solutions of non-linear coupled systems arising in SIR and SIS epidemic models

In this paper, we extend Liao’s newly invented MDDiM for a differential equation to a coupled system of nonlinear differential equations arising in SIR and SIS epidemic models. The method is novel, extended and is applied to the epidemiology models for the first time. Our analytical results agree well with the numerical results obtained by Runge-Kutta method. Errors ranging from 10−5 to 10−17 are obtained for a relatively few terms. Also, MDDiM uses less CPU time. Further, we present error plots and solution curves with numerical results to validate our approximate series solutions. This analytic approach is more general and can be used to analyze complicated models arising in mathematical biology, physics and engineering.

Role of Morphological and Metalinguistic Awareness on Reading among Turkish EFL Learners

This study investigates the effect of morphological treatment on morphological awareness and reading comprehension skill in a foreign language teaching. Experimental design was used in this study which was conducted with 74 freshmen who are studying at Translation and Interpreting Department. Following the Oxford Quick Placement Test and Nation’s Vocabulary Knowledge Test, the participants were divided into two groups as experimental and control groups. Before starting the training process, both groups were pretested with ‘Morphological Correction Test (MCT)’ and ‘Reading Comprehension Test (RCT)’. Following the completion of the pre-test, the treatment period of experimental group for 2 semesters started, while the control group completed the same exercises and studies without focusing on the morphological awareness. Behind the training, post-test study was applied to both groups and the differences were analysed. According to the results, the experimental group outperformed the control group in MCT and RCT. In other words, the morphological awareness of the experimental group increased efficiently; in addition to this, their reading comprehension skills developed as well. Besides, it can be said that the participants benefited effectively and consciously from the explicit training period of morphological awareness and this helped them improve their metalinguistic capacity.
