A nonlinear model for top fuel dragster dynamic performance assessment

The top fuel dragster is the fastest and quickest vehicle in drag racing. This vehicle is capable of travelling a quarter mile in less than 4.5 s, reaching a final speed in excess of 330 miles per hour. The average power delivered by its engine exceeds 7000 Hp. To analyse and eventually increase the performance of a top fuel dragster, a dynamic model of the vehicle is developed. Longitudinal, vertical, and pitching chassis motions are considered, as well as drive-train dynamics. The aerodynamics of the vehicle, the engine characteristics, and the force due to the combustion gases are incorporated into the model. Further, a simplified model of the traction characteristics of the rear tyres is developed where the traction is calculated as a function of the slip ratio and the velocity. The resulting nonlinear, coupled differential equations of motion are solved using a fourth-order Runge–Kutta numerical integration scheme. Several simulation runs are made to investigate the effects of the aerodynamics and of the engine's initial torque in the performance of the vehicle. The results of the computational simulations are scrutinised by comparisons with data from actual dragster races. Ultimately, the proposed dynamic model of the dragster can be used to improve the aerodynamics, the engine and clutch set-ups of the vehicle, and possibly facilitate the redesign of the dragster.
Highly Cited Researchers 2014 and 2015: An investigation of some of the world's most influential scientific minds on the institutional and country level

For several years, Clarivate Analytics, formerly the IP & Science business of Thomson Reuters, has published a list of researchers who have published the largest number of highly cited papers in a particular discipline. These researchers are described by Clarivate Analytics as highly-cited researchers (HCRs) or as some of the world's most influential scientific minds. Whereas the HCR 2014 list refers to the publication years 2002 to 2012, the HCR 2015 list refers to the years 2003 to 2013. The HCR 2015 list contains a total of 3126 researchers worldwide. Compared with the HCR 2014 list which includes 3215 researchers, the 2015 list thus includes 89 fewer researchers as HCRs. This study undertakes a comparison of HCR 2014 and 2015 on the institute and country levels. As the results on the countries show, for HCR 2015, around half the researchers work in the USA; a further ∼10% in Great Britain. About 6% or 5% of the researchers are in Germany or China respectively. In comparison with HCR 2014, no country has lost as many HCRs as the USA with 3.4%. An especially great increase in HCRs occurred in Australia (1.3%), Saudi Arabia (0.7%), Germany (0.5%) and Great Britain (0.5%). The evaluation of the institutional affiliations proves that - based on the primary affiliations - the largest number of HCRs is employed at the University of California, System (n=161). This is followed by Harvard University (n = 95). However, both institutions are also - if one compares HCR 2015 with HCR 2014 - affected by a large decrease in the HCRs (both in numbers of HCR and percentages).
Bilingual word alignment of multi-strategy

Aligning bilingual corpus at the word level is very important to statistical machine translation (SMT). The diversity and feasibility of morphology, semantics and syntax, with out-of-vocabulary words and segmentation error directly or indirectly affect the word alignment. An efficient multi-strategy alignment algorithm is presented, by combining the lexical information, GIZA++ results and HowNet. A set form operation is used to guide the disambiguation process of word alignment, according to the analysis of the bilingual corpus and the alignment result. The experiments show that F-score is 85.07% and increased by 10% over optimized IBM model, and alignment error ratio is decreased by 10%. The strategy complements the advantages of those algorithms according to the reliability and consistence of them.

Choosing an XML database for linguistically annotated corpora

XML has become the de-facto standard for representing linguistically annotated corpora. It seems safe to assume that storing and querying an XML-encoded, annotated corpus in an XML database is a straightforward procedure. In reality, however, it is not. This article aims to provide guidelines for deciding whether to use an XML database and how to choose a suitable product. To this end we examine the following questions: Which aspects should be considered before choosing to store an XML-encoded annotated corpus in an XML database? Which facilities does a database need to provide in order to be suitable for storing and querying annotated corpora? Do current XML databases offer these facilities, and, if not, can they be added?

Wheelie-using a scroll-wheel pen in complex virtual environment applications

Input devices and system control techniques for complex virtual environment (VE) applications are still an open field of research. We propose the use of a scroll-wheel as an extra, dedicated input stream on a tracked stylus for means of system control. We demonstrate how this enhanced stylus can be used together with an appropriate user interface to quickly select commands, change tools, and adjust parameters. This user interface consists of two different styles: a toolbar and a graphical menu system, both accessible by the same hand that holds the stylus. The scroll-wheel extension does in no way impair the conventional use of the stylus.

Implementation of a Connected Digit Recognizer Using Continuous Hidden Markov Modeling

(ABSTRACT) This thesis describes the implementation of a speaker dependent connected-digit recognizer using continuous Hidden Markov Modeling (HMM). The speech recognition system was implemented using MATLAB and on the ADSP-2181, a digital signal processor manufactured by Analog Devices. Linear predictive coding (LPC) analysis was first performed on a speech signal to model the characteristics of the vocal tract filter. A 7 state continuous HMM with 4 mixture density components was used to model each digit. The Viterbi reestimation method was primarily used in the training phase to obtain the parameters of the HMM. Viterbi decoding was used for the recognition phase. The system was first implemented as an isolated word recognizer. Recognition rates exceeding 99% were obtained on both the MATLAB and the ADSP-2181 implementations. For continuous word recognition, several algorithms were implemented and compared. Using MATLAB, recognition rates exceeding 90% were obtained. In addition, the algorithms were implemented on the ADSP-2181 yielding recognition rates comparable to the MATLAB implementation.

LIPID PEROXIDE LEVELS AND ANTIOXIDANT STATUS IN HEALTHY AND ALCOHOLIC HEPATITIS PATIENTS

Background: Alcohol remains the single most significant cause of liver disease throughout the Western world, responsible for between 40 and 80% of cases of cirrhosis in different countries. Material & Methods:The study was conducted in Department of Biochemistry, Santosh medical college & Hospital, Ghaziabad and Veer Chandra Singh Garhwali Govt. Institute of Medical Sciences & Research, 164 alcoholic hepatitis patients were subjected to detailed clinical examination and laboratory investigations and the results were compared with 82controls. Blood samples were collected for oxidative stress parameters. It was observed that there was a significant increase in activities of Catalase, SOD, MDA, GPX and GR activity in patients with alcoholic hepatitis when compared to controls. Results: Results of our study show higher oxygen free radical production, evidenced by elevated levels of MDA and decreased levels of Catalase, SOD, GPx, GR, and TAS activity, supporting the evidence of oxidative stress in alcoholic hepatitis patients. Decreased concentrations of antioxidant support the hypothesis that alcoholic hepatitis is an important causative factor in pathogenesis of lipid peroxidation. Conclusion:Theantioxidant defense mechanisms might be impaired in patients with alcoholic hepatitis. These findings also provide a theoretical basis for development of novel therapeutic strategies, such as antioxidant supplementation. Key words: Alcoholic Hepatitis; Catalase;Glutathione Peroxidase; Glutathione Reductase; Malondialdehyde; Superoxide dismutase; Total antioxidant status.

The Algebraic Operations and Their Implementation Based on a Two-Layer Cloud Data Model

Abstract The existing cloud data models cannot meet the management requirements of structured data very well including a great deal of relational data, therefore a two-layer cloud data model is proposed. The composite object is defined to model the nested data in the representation layer, while a 4-tuple is defined to model the non-nested data in the storage layer. Referring the relational algebra, the concept of SNO (Simple Nested Object) is defined as basic operational unit of the algebraic operations; the formal definitions of the algebraic operations consisting of the set operations and the query operations on the representation layer are proposed. The algorithm of extracting all SNOs from a CAO (Component-Attribute-Object) set of a composite object is proposed firstly as the foundation, and then as the idea; the pseudo code implementation of algorithms of the algebraic operations on the storage layer are proposed. Logic proof and example proof indicate that the definition and the algorithms of the algebraic operations are correct.
Computer Go and Monte Carlo Tree Search: Opening Book and Parallel Solutions

This work examines two aspects of Monte Carlo Tree Search (MCTS), a recent invention in the field of artificial intelligence. We propose a method to guide a Monte Carlo Tree Search in the initial moves of the game of Go. Our method matches the current state of a Go board against clusters of board configurations that are derived from a large number of games played by experts. The main advantage of this method is that it does not require an exact match of the current board, and hence is effective for a longer sequence of moves compared to traditional opening books. We apply this method to two different open-source Go-playing programs. Our experiments show that this method, through its filtering or biasing the choice of a next move to a small subset of possible moves, improves play effectively in the initial moves of a game. We also conduct a study of the effectiveness of various kinds of parallelization of MCTS, and add our own parallel MCTS variant. This variant introduces the notion of using multiple algorithms in the root version of parallelization. The study is conducted across two different domains: Go and Hex. Our study uses a consistent measure of performance gains in terms of winning rates against a fixed opponent and uses enough trials to provide statistically significant results.

Romantic Relationship Satisfaction Levels of Female University Students in Turkey: Examining through Attachment Dimensions, Perceived Abuse in Relationship and Future Time Orientation of Relationship

The study mainly aimed to identify an important task of adolescence, i.e. romantic relationships by investigating possible roles of socio-economic status of families, attachment dimensions, future orientation and perceived abuse in relations on relationship satisfaction of female university students. Moreover, it is aimed to understand the role of being a student of state or private universities, as well as grades, relationship durations, family income, mothers’ and fathers’ education level and marital status of parents’ among perceived abuse in relationship and satisfaction in relationship. To that end, we carried out the research in two different universities whose students have different socio-economic background with the assumption that it has an important role in perceiving abuse as well as in determining the value of romantic relationship.According to findings, students of the private university have more satisfaction in their romantic relationships than students of the state university. Females who are at higher-grades and have relatively longer relationship also have more relationship satisfaction. Besides, according to findings of regression analysis, predictive factors of romantic relationship satisfaction are avoidance attachment, perceived abuse in romantic relationship, anxiety attachment and future time orientation in romantic relationship.
