H R : Extracting and Normalizing Temporal Expressions in Croatian

Temporal expression extraction and normalization are important for many NLP tasks and have been the topic of extensive research. While the majority of research on temporal expression extraction was performed for English, there has recently also been work on temporal processing for other languages. In this paper, we describe HEIDELTIME.HR, the Croatian resources for HeidelTime – a multilingual, cross-domain temporal expression tagger. HeidelTime recognizes temporal expressions in text and normalizes them according to the TIMEX3 annotation standard. We compile WikiWarsHr, a corpus of historical narratives in Croatian manually annotated for temporal expressions. On WikiWarsHr, HEIDELTIME.HR achieves results comparable to those originally achieved by HeidelTime on English texts, with F1-scores of 0.93 and 0.86 for expression extraction and normalization, respectively. HEIDELTIME.HR: luščenje in normaliziranje časovnih izrazov v hrvaščini Luščenje in normalizacija časovnih izrazov sta pomembna za raznovrstne naloge s področja računalniške obravnave naravnega jezika in sta bila predmet številnih raziskav. Medtem ko je bila večina raziskav luščenja časovnih izrazov opravljenih za angleščino, pa so bile v zadnjem času raziskave izvedene tudi za druge jezike. V prispevku opišemo HeidelTime.Hr, hrvaške vire za HeidelTime – večjezični in prekdomenski označevalec za časovne izraze. HeidelTime prepozna časovne izraze v besedilu in jih normalizira glede na standard za označevanje TIMEX3. Izdelamo WikiWarsHr, korpus zgodovinskih pripovedi v hrvaščini, ki je bil ročno označen za časovne izraze. Na WikiWarsHr doseže HeidelTime.Hr rezultate, primerljive s tistimi, ki jih je HeidelTime dosegal na angleških besedilih, z mero F 0,93 za luščenje in 0,86 za normalizacijo časovnih izrazov.

Modeling and control of a motor system using the Lego EV3 robot

In this thesis, I present my work on the modeling and control of a motor system using the Lego EV3 robot. The overall goal is to apply introductory systems and controls engineering techniques for estimation and design to a real-world system. First I detail the setup of materials used in this research: the hardware used was the Lego EV3 robot; the software used was the Student 2014 version of Simulink; a wireless network was used to communicate between them using a Netgear WNA1100 wifi dongle. Next I explain the approaches used to model the robot’s motor system: from a description of the basic system components, to data collection through experimentation with a proportionally controlled feedback loop, to parameter estimation (through time-domain specification relationships, Matlab’s curve-fitting toolbox, and a formal least-squares parameter estimation), to the discovery of the effects of frictional disturbance and saturation, and finally to the selection and verification of the final model through comparisons of simulated step responses of the estimated models to the actual time response of the motor system. Next I explore three different types of controllers for use within the motor system: a proportional controller, a lead compensator, and a PID controller. I catalogue the design and performance results – both in simulation and on the real system – of each controller. One controller is then selected to be used within two Controls Systems Engineering final course projects, both involving the robot traveling along a predetermined route. The controller’s performance is analyzed to determine whether it improves upon the accumulation of error in the robot’s position when the projects are executed without control.
Incorporating Synonyms into Snippet Based Query Recommendation System

Recently, growth of internet has been increased for information retrieval though it is difficult to extract the relevant information in less time. Search engine sometime fails to understand user search intend. Query recommendation can be used to help user to state exactly their information need. Search engine can return appropriate result to meet users’ information needs. There are various methods based on history of users and snippets to retrieve the information. But these methods fail to satisfy users need. Therefore in addition of history and snippets with synonyms will do better. Moreover user preferences can be used to build the user profile which will help in effective recommendations. Here for given query recommendation the synonyms are extracted on line. Synonym based method ranks the clicked URLs at the top of the result based on user profile. The performance of the system shows that the synonym based approach give better and effective recommendation for all queries as compared to previous methods.
Feature-Based Solid Model Reconstruction

In this paper, we propose an effective solution to reconstruct solid models of existing objects. Specifically, we convert the model reconstruction problem into the issue of feature parameter extraction, and thereby design diverse methods to extract the parameters of basic design features from input surface meshes. After extracting the feature parameters, the corresponding features are constructed. By performing modeling operations on those features, the final solid model is constructed, and meanwhile the complete history of the model building operations is recorded. By introducing the concepts of “feature,” “constraint,” and “modeling history” into the reconstruction process, the design intent is captured and hence represented in the reconstructed model. As a result, the model is geometrically accurate and topologically consistent, and moreover it is flexibly editable, which makes it convenient to carry out model redesign and modification for the innovation applications. A variety of experimental results demonstrate the effectiveness and robustness of this solution. [DOI: 10.1115/1.4023129]
FONT-CONVERSION SYSTEMS FOR INDIAN LANGUAGES

A large amount of data in Indian languages stored digitally is in ASCII-based font formats. ASCII has 128 character-set, therefore it is unable to represent all the characters necessary to deal with the variety of scripts available worldwide. Moreover, these ASCII-based fonts are not based on a single standard mapping between the character-codes and the individual characters, for a particular Indian script, unlike the English language fonts based on the standard ASCII mapping. Therefore, it is required that the fonts for a particular script must be available on the system to accurately represent the data in that script. Also, the conversion of data in one font into another is a difficult task. The non-standard ASCII-based fonts also pose problems in performing search on texts in Indian languages available over web. There are 25 official languages in India, and the amount of digital text available in ASCII-based fonts is much larger than the text available in the standard ISCII (Indian Script Code for Information Interchange) or Unicode formats. This paper discusses the work done in the field of font-detection (to identify the font of the given text) and font-converters (to convert the ASCII-format text into the corresponding Unicode text).
Prevalence of phylogenetic clustering at multiple scales in an African rain forest tree community

In highly diverse ecosystems, such as tropical forests, the relative importance of mechanisms underlying species coexistence (e.g. habitat filtering, competitive exclusion, neutral dynamics) is still poorly known and probably varies depending on spatial and phylogenetic scales. Here, we develop new approaches for dissecting simultaneously the phylogenetic structure of communities at different phylogenetic depths and spatial scales. We tested with simulations that our method is able to disentangle overdispersion and clustering effects occurring at contrasted phylogenetic depths. We applied our approaches to a 50 ha Forest Dynamic Plot located in Korup National Park (Cameroon) where 329,000 tree stems ≥ 1 cm in diameter were identified and mapped, and using a newly generated dated molecular phylogenetic tree based on 2 plastid loci (rbcL and matK), including 272 species from Korup (97% of the individuals). Significant patterns of phylogenetic turnover were detected across 20 × 20 m2 quadrats at most spatial scales, with higher turnover between topographic habitats than within habitats, indicating the prevalence of habitat filtering processes. Spatial phylogenetic clustering was detected over the entire range of phylogenetic depths indicating that competitive exclusion does not generate a pattern of phylogenetic overdispersion at this scale, even at a shallow phylogenetic depth. Using an individual‐based approach, we also show that closely related species tended to aggregate spatially until a scale of 1 m. However, the signal vanishes at smaller distance, suggesting that competitive exclusion can balance the impact of environmental filtering at a very fine spatial scale. Synthesis. Using new methods to characterize the structure of communities across spatial and phylogenetic scales, we inferred the relative importance of the mechanisms underlying species coexistence in tropical forests. Our analysis confirms that environmental filtering processes are key in the structuring of natural communities at most spatial scales. Although negative‐density tends to limit coexistence of closely related species at very short distance (<1 m), its influence is largely veiled by environmental filtering at larger distances.
Plan Explanation Through Search in an Abstract Model Space *

There is a growing interest within the AI research community in developing autonomous systems capable of explaining their behavior to users. However, the problem of computing explanations for users of different levels of expertise has received little research attention. We propose an approach for addressing this problem by representing the user’s understanding of the task as an abstraction of the domain model that the planner uses. We present algorithms for generating minimal explanations in cases where this abstract human model is not known. We reduce the problem of generating an explanation to a search over the space of abstract models and show that while the complete problem is NP-hard, a greedy algorithm can provide good approximations of the optimal solution. We also empirically show that our approach can efficiently compute explanations for a variety of problems.
Laissez Fear: Assessing the Impact of Government Involvement in the Economy on Ethnic Violence

Does government involvement in the economy promote ethnic peace, or does it contribute to ethnic violence? Two theories, grievances and opportunity, suggest that government involvement in the economy reduces ethnic violence. We present an alternative security-based logic that focuses on the role of economic rents in political competition. Our theory of insecurity predicts that free market economies reduce violent ethnic conflict by reducing fear and insecurity. We present statistical analyses, using data from the Minorities at Risk project and the Index of Economic Freedom, showing that government involvement in the economy increases ethnic rebellion. Our results suggest that the overall size of the public sector is less important than government interference with the market allocation mechanism. We conclude by discussing the policy implications of our findings.
Stabilization of Transition Metal Chromite Nanoparticles in Silica Matrix

—This article presents summary on preparation and characterization of zinc, copper, cadmium and cobalt chromite nanocrystals, embedded in an amorphous silica matrix. The ZnCr 2 O 4 /SiO 2 , CuCr 2 O 4 /SiO 2 , CdCr 2 O 4 /SiO 2 and CoCr 2 O 4 /SiO 2 nanocomposites were prepared by a conventional sol-gel method under acid catalysis. Final heat treatment of the samples was carried out at temperatures in the range of 900 − 1200 ◦ C to adjust the phase composition and the crystallite size, respectively. The resulting samples were characterized by Powder X-ray diffraction (PXRD), High Resolution Transmission Electron Microscopy (HRTEM), Raman/FTIR spectroscopy and magnetic measurements. Formation of the spinel phase was conﬁrmed in all samples. The average size of the nanocrystals was determined from the PXRD data and by direct particle size observation on HRTEM; both results were correlated. The mean particle size (reviewed by HRTEM) was in the range from ∼ 4 to 46nm. The results showed that the sol-gel method can be effectively used for preparation of the spinel chromite nanoparticles embedded in the silica matrix and the particle size is driven by the type of the cation A 2+ in the spinel structure and the temperature of the ﬁnal heat treatment. Magnetic properties of the nanocrystals were found to be just moderately modiﬁed in comparison to the bulk phases.
A DUAL PROCESS APPROACH TO EMOTIONAL MEMORY: EFFECTS OF EMOTION ON FAMILIARITY AND RETRIEVAL PROCESSES IN RECOGNITION

Research has indicated that emotion affects recognition memory by either increasing the hit rate and the false alarm rate (Windmann & Kutas; Windmann & Kruger, 1998), or by having selective effects on the hit rate (Maratos & Rugg, 2001). However, the recognition memory process that underlies these effects of emotion is not known. The purpose of this research was to determine the memory retrieval processes by which emotion influences recognition of items that are intrinsically emotional (Experiments 1 and 2) or that were associated with an emotional item during encoding (Experiment 3). Three response-signal associative recognition experiments are reported that demonstrate that emotion increases the proportion of "old" judgments for familiarity-based recognition judgments. In Experiment 1, emotional words were associated with a familiarity-based increase in the hit rate at short response lags. Experiment 2 demonstrated that this effect of emotion was driven by the arousal associated with the words, not their valence. And in Experiment 3, a familiarity-based effect of emotion was observed for neutral words that had been encoded in an emotional context. Taken together, these results suggest that emotion has a fast acting, low-level effect on recognition memory that is independent of the unique perceptual features of emotional items.
Dynamic molecular imaging of cardiac innervation using a dual headpinhole SPECT system

Typically 123I-MIBG is used for the study of innervation and function of the sympathetic nervous system in heart failure. The protocol involves two studies: first a planar or SPECT scan is performed to measure initial uptake of the tracer, followed some 3-4 hours later by another study measuring the wash-out of the tracer from the heart. A fast wash-out is indicative of a compromised heart. In this work, a dual head pinhole SPECT system was used for imaging the distribution and kinetics of 123I-MIBG in the myocardium of spontaneous hypertensive rats (SHR) and normotensive Wistar Kyoto (WKY) rats. The system geometry was calibrated based on a nonlinear point projection fitting method using a three-point source phantom. The angle variation effect of the parameters was modeled with a sinusoidal function. A dynamic acquisition was performed by injecting 123I-MIBG into rats immediately after starting the data acquisition. The detectors rotated continuously performing a 360o data acquisition every 90 seconds. We applied the factor analysis (FA)method and region of interest (ROI) sampling method to obtain time activity curves (TACs)in the blood pool and myocardium and then applied two-compartment modeling to estimate the kinetic parameters. Since the initial injection bolus is too fast for obtaining a consistent tomographic data set in the first few minutes of the study, we applied the FA method directly to projections during the first rotation. Then the time active curves for blood and myocardial tissue were obtained from ROI sampling. The method was applied to determine if there were differences in the kinetics between SHR and WKY rats and requires less time by replacing the delayed scan at 3-4 hours after injection with a dynamic acquisition over 90 to 120 minutes. The results of a faster washout and a smaller distribution volume of 123IMIBG near the end of life in the SHR model of hypertrophic cardiomyopthy may be indicative of a failing heart in late stages of heart failure.

Systems biology is based on the understanding that the behaviour of the whole is greater than would be expected from the sum of its parts. Thus the ultimate goal of systems biology is to predict the behaviour of the whole system on the basis of the list of components involved. Recent advances in ‘-omics’ technologies and the development of new computational techniques and algorithms have greatly contributed to progress in this fi eld of biology. Among the main ‘-omics’ technologies, metabolomics is expected to play a signifi cant role in bridging the phenotype–genotype gap, since it amplifi es changes in the proteome and provides a better representation of the phenotype of an organism than other methods. However, knowledge of the complete set of metabolites is not enough to predict the phenotype, especially for higher cells in which the distinct metabolic processes involved in their production and degradation are fi nely regulated and interconnected. In these cases, quantitative knowledge of intracellular fl uxes is required for a comprehensive characterization of metabolic networks and their functional operation. These intracellular fl uxes cannot be detected directly, but can be estimated through interpretation of stable isotope patterns in metabolites. Moreover, analysis of these fl uxes by means of metabolic control theories 1To whom correspondence should be addressed (email martacascante@ub.edu). © The Authors Journal compilation © 2008 Biochemical Society
A comparative analysis of international education satisfaction using servqual

University education, the world over, has undergone significant transformation and reform with respect to higher education systems meeting the growing role of information and communication revolution, and the demand for knowledge, which represent the new challenges of globalisation . These challenges are seen as threats as well as opportunities for higher education systems around the world. The driving force of globalisation is competition and the international education market has become fiercely competitive with different marketing strategies being implemented by educational institutions to attract the growing number of students seeking higher education. The objective of this paper is to examine the relationship between the SERVQUAL constructs proposed by Parasuraman et al (1988 & 1985) and the country of origin and satisfaction among four cohorts of Asian international postgraduate students studying in Australian universities. Country of origin is recognized as an important predictor of satisfaction and choice in the international education environment. The data used in this study is derived from a mail survey conducted among international postgraduate students from China, India, Indonesia and Thailand studying in five universities in Victoria, Australia. An adapted version of the SERVQUAL instrument was used to collect the data and was designed to measure the gap between student responses on expectations and perceptions of the university as a study destination on a seven point bi-polar scale. The responses were sought on 36 statements representing aspects of the operations and services of the university under desired (ideal) expectations of choice and post-choice perceptions. Scales were developed to investigate the relationship between the SERVQUAL constructs of reliability, responsiveness, assurance, empathy and tangibles and the country of origin and were shown to be reliable. Using ANOVA and MANOVA techniques, the study found significant differences between country of origin and the SERVQUAL constructs and discusses strategic implications and opportunities for higher educational institutions.
Ethical Leadership: A Multifoci Social Exchange Perspective

In this conceptual paper, I advocate a multifoci social exchange perspective on ethical leadership for the first time. I propose that social exchange relationships form between ethical leaders at organizational and supervisory levels and that these relationships, especially under certain circumstances (person and contextual factors), impact a broad range of important subordinate attitudinal and behavioral outcomes, including many that are unrelated to ethics but highly beneficial for organizations. Summarizing these propositions into a single conceptual model, I present a comprehensive multifoci social exchange model of ethical leadership and briefly discuss the theoretical and potential practical implications of this model.
