A MODELLING APPROACH FOR CONSERVATION OF EUROPEAN EEL (Anguilla anguilla) AND RELATED FISHERIES

Although the main features of the continental phase of European eel’s (Anguilla anguilla) biological cycle are currently well-known, realistic and well tuned demographic models based on long-term studies are still needed. Age-length data from a 11-year monitoring of the European eel population of the Camargue lagoons (Rhône delta, Southern France) were collected for glass, yellow and silver eels. Three distinct models were calibrated to describe the growth process of undifferentiated eels, females and males, respectively. Uncertainty of parameter estimates was evaluated by bootstrapping. Females were characterized by larger asymptotic body size than males (580±50 vs. 388±13 mm) and faster growth, whilst the Brody growth coefficient was larger for males than for females (3.00·10±1.68·10 vs. 1.73·10±0.50·10). Sexual differentiation was estimated to begin at 204±38 mm, i.e., at the end of the second year of permanence in the lagoons, well before the length at which macroscopic differentiation becomes possible (about 300 mm), but consistently with histological observations. Males are likely to leave the lagoon or die (due to either natural or fishing mortality) within the first three years, whilst females can remain up to five years. Sexual differentiation and maturation have a major role in shaping the length structure of the population. Length-weight data were fitted by allometric curves (W = a L). The calibration of distinct curves for data from different years evidenced that the allometric coefficient a is subject to wider inter-annual fluctuations than the allometric exponent b. A negative correlation links average body length and allometric exponent (r = –0.58, P<<0.01).
Study of DYS 390 Polymorphism among Khatri Population of Punjab in Comparison to Other Indian and World Population

Abstract The Y chromosome specific polymorphism (Y-STR and Y-SNPs) can be used to track paternal lineages as well as male specific movements and admixture among humans. The objective of the present work is to study the genetic polymorphism at Y chromosome specific STR locus, DYS390 among Khatri population of Punjab and generate a comparative data with respect to other Indian and world populations. The DNA was isolated from blood samples of Khatri male individuals through organic method and were amplified by PCR using specific primers for DYS390 locus. The PCR products were electrophoresed on polyacrylamide gels and silver staining was done to resolve and observe different alleles. Gel-Pro 3.1 software was used to confirm the allele size. Chi-Square test was applied to test whether differences between the allele frequencies among Khatri, other Indian and world populations were statistically significant. Network Joining (NJ) tree was constructed using Network analysis software. The results showed 7 different alleles ranging from 22 to 28 in Khatri population and revealed a significantly high degree of genetic heterogeneity at this locus. The gene diversity was found to be 0.8363. The Network Joining tree showed Khatri population as an independent branch alongside Chinese. Therefore, it can be inferred that Khatri population is probably a result of conglomeration of different lineages, like most other North-West Indian population.
Global Cooling: Effect of Urban Albedo on Global Temperature

In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 2025%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 1020% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3x10 -4 in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of ~0.2 years in global warming. This 0.2 years delay in global warming is equivalent to 10 Gt reduction in CO2 emissions.
Why Verb Meaning Matters to Syntax

Since Gruber (1965) and particularly Fillmore (1968), it is known that we can predict a lot of the syntax of verbs from their meaning. To quote Green (1974) or thirty years later Koenig and Davis (2006): ‘Syntactic properties of lexical items depend crucially and in regular ways on the meaning of those lexical items’ (Green 1974) ‘It is widely accepted that the semantic content of a lexical entry determines to a large extent its syntactic subcategorization’ (Koenig & Davis 2006)
Using geographically weighted regression to forecast rail demand in the Sydney Region

This paper is centred on using Geographically Weighted Regression (GWR) to investigate the spatial variability in the factors which influence rail demand patterns in the Sydney region of New South Wales, and to explicitly incorporate these variations in the demand forecasting process. It explores whether allowing spatial parameter variability to be included in demand models enhances their explanatory power and improves their forecasting capability. The paper firstly reviews the different methodologies in use for estimating and forecasting demand, both in the Sydney region and elsewhere around the world. Against this background the methodology of GWR is explained, identifying the key differences in both inputs and outputs of a GWR based model. The paper then describes the development of ‘conventional’ global regression models of rail demand in the Sydney region, and reports on the recalibration of the most successful model using GWR. A large number of explanatory variables are tested in the models, including catchment population and employment, household size, income and age profile, car ownership levels, train frequency, bus interchange potential, bicycle storage provision and distance to the city centre. The results from the global and GWR models are then compared, with the significance of the spatial variation in the GWR models tested using an AICc-based criterion. This comparison informs a discussion of the extent to which modelling spatial parameter variation contributes to a better understanding of rail demand and its forecasting. The discussion concludes by identifying the relative merits of the developed GWR models as compared to other models for forecasting rail travel.
IMPROVING THE RELIABILITY OF FREQUENCY DO- MAIN SIMULATORS IN THE PRESENCE OF HOMO- GENEOUS METAMATERIALS | A PRELIMINARY NU-

The accuracy of the flnite difierence frequency domain (FDFD) method in the solution of canonical waveguide discontinuity problems involving complementary or nearly complementary metama- terials (MTMs) is analytically discussed. It is shown that the good accuracy of the method (in comparison with other frequency-domain techniques) is due to the intrinsic approximation which it introduces in the flnite-difierence discretization of sharp dielectric interfaces. By exploiting such a result, a perturbation algorithm is proposed for the reliable modeling of MTMs devices when other frequency domain nu- merical methods are at disposal. A preliminary numerical analysis is carried out to assess the reliability and accuracy of the proposed modeling approach when canonical scattering problems are at hand.
Interpretação gravimétrica na Borda Norte do Cráton do Congo, Sul de Camarões

Gravity data in the southern Cameroon are interpreted to better understand the organization of underlying structures throughout the northern edge of the Congo craton. The Bouguer anomaly maps of the region are characterized by an elongated SW-NE trending negative gravity anomaly which correspond to a collapsed structure associated with a granitic intrusion beneath the center of the region and limited by fault systems. We applied 3-D gravity modelling and inversion in order to obtain the 3-D density structure of the area. Our result demonstrated that observed gravity anomalies in the region are associated to tectonic structures in the subsurface. The resulting model agrees with the hypothesis of the existence of a major continental collision zone between the Congo Craton and the Pan-African belt. The presence of deep granulites structures in the northern part of the region expresses a continental collision.
La entrevista sociolingüística: esquemas de perspectivas

espanolEste estudio analiza la entrevista sociolinguistica desde unos planteamientos cognitivos. La entrevista sociolinguistica es analizada como un escenario comunicativo y para ello se propone, como punto de partida, el concepto de 'escenario discursivo' (Palmer 2000), interpretado como modelo cognitivo de interaccion formado por esquemas de actos de habla. Los 'esquemas' son categorias analiticas que dan cuenta de diferentes dimensiones de la interaccion. Mediante la aplicacion de estos esquemas, la identificacion de los participantes en la interaccion, el establecimiento del objetivo con que se emiten los discursos, la ordenacion de las secuencias y la percepcion del complejo conversacional, es posible llegar a una caracterizacion de la entrevista sociolinguistica mucho mas completa que las practicadas comunmente. EnglishThis paper examines the sociolinguistic interview from a cognitive approach. The sociolinguistic interview is analyzed as a communicative scenario. As a starting point, it is proposed the concept of 'discursive scenario' (Palmer 2000), interpreted as a cognitive model of interaction built by patterns of speech acts. 'Schemes' are analytical categories that account for different dimensions of interaction. The application of these schemes, the identification of participants in the interaction, the establishment of objective statements, the organization of the sequences and the perception of complex conversational, all these factors will make possible to characterize the sociolinguistic interview in a more complete way than commonly practiced.
PROPOSING A STANDARDS-BASED NATIONAL FRAMEWORK: CASE FROM NORTHERN CYPRUS

All items in the By-Law of Teachers in Northern Cyprus are based on general principles where the quality of education system in Northern Cyprus has been affected negatively. The goal of this study is to propose a standards-based national framework for Northern Cyprus. Therefore, the aim of the study is to identify the necessary-process (NP), dimensions (Ds), sub-dimensions (SDs) professionalteaching-standards (PTSs), and performance statements (PSs) as a nationalframework for Northern Cyprus (NC). Case study under qualitative paradigm was used as the research strategy in this study. Participants were 19 educationalexperts-for-necessary-process (EEfNP) and 43 study-group-members (SGMs). Various data collection instruments were applied. For data analysis, recorded interviews were transcribed. Through content analysis, data were put into categories and then themes and sub-themes were identified. The qualitative data yielded category 1, necessary-process. Then, category 2 on dimensions and subdimensions was generated. Category 3, PTSs, was produced and finally, category 4, PSs, was generated. As a result of the face-to-face interviews with the participants, 3 dimensions, 10 SDs, 25 PTSs 98 PSs were generated.
A Model Based on Cocitation for Web Information Retrieval

According to the relationship between authority and cocitation in HITS, we propose a new hyperlink weighting scheme to describe the strength of the relevancy between any two webpages. Then we combine hyperlink weight normalization and random surfing schemes as used in PageRank to justify the new model. In the new model based on cocitation (MBCC), the pages with stronger relevancy are assigned higher values, not just depending on the outlinks. This model combines both features of HITS and PageRank. Finally, we present the results of some numerical experiments, showing that the MBCC ranking agrees with the HITS ranking, especially in top 10. Meanwhile, MBCC keeps the superiority of PageRank, that is, existence and uniqueness of ranking vectors.
Enhanced Exemplar Based Inpainting Using Patch Ratio

Image inpainting is the art of modyfing part of image or video that cannot detectable by ordinary observer. There are two different classes of algorithms for inpainting. Texture synthesis, and geometric partial differential equations(PDEs). We think that we don’t have to make new color in image so we only focus on find the best matching pixels for each unknown pixels. In this paper, we suggest a new method based on exemplar based inpainting. The method is suggested by Criminisi et al. [1]. But its method takes a long time, but also cannot give a good result for some cases. First, we analyze deficiency of Criminisi algorithm and then we offer a new algorithm. Our algorithm uses a modified calculation for priority and then uses patch ratio for finding the best candidates. For faster computing, we use window and number of nonzero elements of candidates. Finally, among the candidates we concern about gradients of the template.
Fingerprint and Face Recognition: Application to Multimodal Biometrics System

Multimodal biometrics systems combine different unimodal biometric sources to achieve high recognition accuracy. By overcoming the limitation of unimodal biometric systems in this paper, a multimodal biometric recognition system which combines two modalities, fingerprint and face based on score level fusion is proposed. For fingerprint trait, the features are built based on the minutiae points of ridge area, while Local Binary Patterns (LBP) is used for face trait. The procedures of pre-processing, features extraction and matching are proceeding independently to obtain the individual matching scores. Afterwards, the two calculated results are combined by a matching score level fusion scheme to make the final decision on declaring the person as genuine or an imposter.
Microstructures and Properties for a Superalloy Powder Mixture Processed by Electron Beam Melting

The microstructures and residual hardnesses for solid components of 2-phase TiAl (Ti-48Al-2Nb-2Cr in a / o ) and Inconel 625 (Ni-19Cr-9Mo-4Nb in w / o ) fabricated by electron beam melting (EBM) were compared with a 10:1 blend of TiAl: alloy 625 pre-alloyed powders producing a complex alloy having the composition 48Ti-24Al-9Ni-8Nb-4.5Cr-4Ni (in w / o ). The blended alloy hardness (HV) reached 7.5 GPa in contrast to 1.4 GPa for the Alloy 625 and 4.0 for the 2-phase TiAl alloy. Reticulated mesh samples and stochastic foam samples prepared from the blended alloy by EBM exhibited a relative stiffness versus relative density plotted on a log-log basis consistent with other reference alloys fitted to a straight line with a slope n = 2 for ideal open cellular materials.
On the Presence of a Day-ofthe-Week Effect in the Foreign Exchange Market

The purpose of this paper is to study the presence of the day-of-the-week effect in the foreign exchange market using an extensive data set of six exchange rates and employing two alternative types of distributional assumptions and also distribution-free tests. Our findings support the hypotheses of higher Wednesday returns prior to October 1, 1981, for the British pound, the Canadian dollar, the Deutsch mark, the French franc, the Swiss franc and the Japanese yen. Pursuant to the change in the settlement procedures which took effect October 1, 1981, the differential Wednesday returns disappear.
Collecting and Using Data to Develop Digital Learning Culture at School

The use of ICT in schools is varied and can change quickly. In this paper, we present a new way of measuring and doing research on ICT in schools that combines ICT research with ICT development in a mutually beneficial way. We have developed a web service that helps schools in their own ICT development. The tool called Opeka has been widely adopted and now produces new information regularly. The information works on three levels: First, it gives immediate feedback to the teacher about their use of ICT in education. Second, it provides the principals and school communities information on how their school is doing in the use of ICT and provides comparative information. And third, it is useful for developers, decision makers and politicians on town, province or nation level. The tool can become an integral part of the development cycle of any municipality or school. The Opeka service can also be seen as a help in finding and identifying the problems in ICT use of schools in the same way that learning analytics do but with a focus on teaching instead of learning. The system could even be seen as nudge analytics, where the idea is to create analytics that can nudge the users in a good direction, in our case to nudge teachers to use ICT in their teaching.
Stream programming framework for global ilumination techniques using a GPU

Stream processors are becoming an affordable alternative to implement hardware assisted rendering techniques which were usually relegated to offline usage. We built a stream processing framework based on the Stream Programming Model concepts, selected the Photon Mapping algorithm and an NVIDIA GPU (Graphics Processing Unit) as a test case implementation of a Global Illumination technique. We defined a set of C++ classes to encapsulate the components (kernels and streams) of this new paradigm, using OpenGL and Cg language. Our application combines the Photon Splatting method and the BVH (Bounding Volumes Hierarchy) acceleration structure into a rendering pipeline relying almost entirely on the GPU. Finally, we evaluated its performance using a Cornell Box model.
Flight Envelope Calculation of a Hypersonic Vehicle Using a First Principles-Derived Model

Steady, level flight for an air-breathing hypersonic vehicles requires balancing intricate couplings among the engine, lifting surfaces, and control effectors. A newly developed fundamental model is used to determine the range of flight Mach numbers and altitudes at which this balance can be obtained. The hypersonic vehicle was developed specifically for flight dynamics evaluations, and the model can calculate the net forces and moments on a three-dimensional vehicle in less than ten seconds using a single 2.6 GHz processor. The propulsive model includes complex physics such as wave interactions, fuel mixing, and finite-rate chemistry. This type of model requires less computational resources than a model based on computational fluid dynamics and provides a more accurate characterization of the flight envelope than simplified models could.
A Parallel Genetic Algorithm and Its Variance Analysis for A New Multiple Knapsack Problem

This paper presents some results of experimental evaluation on the fitness varieties in parallel genetic algorithms based on tree topology migrations. The evaluation focuses on the relation between the solution quality and the fitness varieties. We perform the evaluation for the typical tree topologies; the star, line, and balanced binary tree with varying migration interval since the solution quality of the parallel genetic algorithm depends on the kind of the topology and migration interval. The results show that the line topology can keep the chromosome variety of the GA and obtain better quality of solutions since the topology has the longest distance between the root and the leaves.
Comment définir et classer les maladies inflammatoires ? How to define and to classify inflammatory systemic diseases ?

Ces maladies inflammatoires étaient définies jusqu’à présent par des critères cliniques et biologiques validés par l’usage et l’avis d’experts. Cependant, leur polymorphisme suggère qu’une même entité puisse être liée à des mécanismes moléculaires différents. À titre d’exemple, la polyarthrite rhumatoïde (PR) est une maladie articulaire parfois extrêmement agressive ou inversement une forme bénigne non destructrice. S’agit-il de la même affection ou d’affections différentes ? Jusqu’à présent, il était difficile d’envisager « d’affiner » la classification de ces maladies, mais de nouveaux outils immunitaires et/ou
Prospective Teachers' Use of Representations in Solving Statistical Tasks with Dynamic Statistical Software

This study examined a random stratified sample (n=62) of prospective teachers' work across eight institutions on three tasks that utilized dynamic statistical software. Our work was guided by considering how teachers may utilize their statistical knowledge and technological statistical knowledge to engage in cycles of investigation. Although teachers did not tend to take full advantage of dynamic linking capabilities, they utilized a large variety of graphical representations and often added statistical measures or other augmentations to graphs as part of their analysis
Effects of extractants on the yields and selected chemical characteristics of humic acids isolated from tropical saprists peat

Problem statement: Humic acids are beneficial to soil aggregation, binding of heavy metal, plant growth and many more. However, the isolation of Humic Acids (HA) from its origin is not only time-consuming, but the isolation is also affected by factors such as temperature and the types of extractants and their concentrations. Different concentrations of extractant are said to alter the chemical characteristics of HA. Although this kind of information is important in HA studies, it is lacking for tropical peats. Approach: This study was conducted to investigate the yields and selected chemical element contents of HA isolated from tropical saprists peat as affected by NaOH and KOH with different concentrations. Humic acids were isolated from tropical saprists peat taken from Sarawak, Malaysia. Yields of HA and selected chemical properties were determined using standard procedures. Results: Yields of HA isolated using different concentrations of NaOH and KOH showed significant difference at each level of concentrations. For the chemical characteristics tested, only total acidity showed no significant difference. For TOC and ash, the KOH used exhibited inconsistent results compared to that of NaOH. As for E4/E6 values, the high values obtained suggests that HA in Sarawak peats contain relatively lower molecular weight. Conclusion: For the purpose of studying chemical characteristics, 0.2, 0.3 and 0.4 M of both NaOH and KOH were good enough to be used in isolating HA. This is because the results of study showed that these 3 levels of concentrations yielded HA with more homogenous chemical characteristics. On the other hand, extractants with higher concentrations are preferred when the yield of HA is of concern.
