Immersive First Person Virtual Reality

Virtual Reality through head-mounted displays (HMD) has great potential for further development in various applications. There are still several problems that must be solved in order to make a product such as this, mainstream. Besides creating a lacking immersive virtual reality experience, fundamental issues such as time lag and motion sickness need to be resolved. This can be done with more dedicated research into the efficiency and accuracy of sensor hardware and the sensor fusion algorithms that utilize the data. Putting more time and money into developing an efficient approach to multi-sensor data fusion will not only lower the costs of hardware, but also improve the users immersive experience and make it a true virtual reality. This paper analyzes the history, technical underpinnings, a demonstration, and future trends of immersive first person virtual reality.
The investigation on the relationship between dairy cow hygiene scores and intramammary infections

The “cow hygiene score” system is a management tool for assessment of cow’s body hygiene and cleaning of the barn. In this study, the correlation between body hygiene scores and intramammary infections (IMI), California Mastitis Test (CMT) and Somatic Cell Count (SCC) were evaluated in two different seasons. Hygiene scoring of 1096 dairy cows in 4 herds was performed on five body areas including: udder, rear legs, flanks and upper legs, abdomen, and tail head. After doing CMT, milk samples were taken from quarters with score 2 or more for microbiological culture. SCC data were taken in two consecutive months. The results of this study showed no significant differences between the median of all hygiene scores except for tail head that were significantly greater in high than low rainy seasons (p 0.05), but a statistically significant relationship was found between udder hygiene score and isolation of environmental bacteria (p 0.05). Finally, it seems that udder hygiene scoring is an useful tool for predicting of intramammary infections caused by environmental bacteria.
Broad-band gap coupled microstrip antenna

A microstrip antenna with large bandwidth is developed using a parasitic technique. Compared to the available wideband antennas, the proposed antenna structure is very compact and gives a less distorted radiation pattern with frequency. An impedance bandwidth eight times that of a conventional patch antenna of the same size is achieved. The concept of coupled microstrip line model is extended for theoretical interpretation of the impedance loci. The experimental procedure and results are described, and a theoretical analysis is presented. >
SHIFTING MEDIA USES AND GRATIFICATIONS AMONG SINGAPOREAN TEENS AND UNIVERSITY STUDENTS: A FUTURE RIPE FOR MOBILE APPLICATIONS

An exploratory study examining the various opportunities and challenges facing advertisers wanting to reach the teen and young adult segments of the future was undertaken in Singapore. Media patterns from traditional channels to the Internet and mobile phones were assessed to provide a context for the study. Beyond frequency of use, actual online and mobile phone activities were assessed. In the case of mobile phones, everything from talking on the phone and text messaging to receiving advertisements were examined. Implications for advertisers are discussed.
Multiple Perspectives on Charter School Accountability: Research Findings from Charter Schools and Charter School Authorizers.

This paper presents national 2000-01 data from charter schools and charter-school authorizers in the United States regarding the various stages of the accountability process: the charter application stage, the monitoring stage, and the sanctions stage. The larger accountability context of public schools and its impact on charter schools are also discussed. The paper concludes with a discussion of the continuing mismatch between the theory and the reality of charter-school accountability. The authors maintain that the original vision of charter-school-level goalsetting is being eclipsed by state assessment mandates and other accountability requirements. Furthermore, charter-school accountability relationships continue to emphasize traditional inputs at most stages of the accountability process, especially during the implementation of sanctions against schools. Hence, the original theory of charter-school accountability is compromised by the continuing emphasis on inputs, on one hand, and by externally defined and imposed outcomes measures on the other.

Dictionary of Valencies Meets Corpus Annotation: A Case of Russian FrameBank

The Russian FrameBank project aims at the development of a hybrid lexical resource that links a dictionary of valencies and an annotated corpus. Two types of data present generalized lexical constructions (LexCxs) and their realizations in contemporary written texts (1950-present). The predicate-argument structure for verbs, nominalizations, adjectives, adverbs, and other lexical units in Russian is mostly encoded in case and prepositional marking while word alignment is determined by information structure. This means that an argument can be found in any part of the sentence and the window for argument detection is infinitely wide. Russian predicates reveal more than 1000 typical morphosyntactic patterns; the number of shallow realizations under certain grammatical and discourse constraints is even greater. Morphosyntactic patterns are not fully predictable by semantics (Apresjan 1967), and, hence, we can speak here about lexical constructions. The patterns with lexical slots evoked by two or more target lexemes (e.g. idiomatic phrases like vzjal i <uexal> ‘he suddenly (lit. took and) <went away>’) are also treated as LexCxs. As experiments on unsupervised LexCx retrieval have shown (Toldova et al. 2008, Lashevskaja and Mitrofanova 2009), there is a great need for an open data pool annotated manually for lexical frames. In a wider perspective, the project on tagging the form and meaning pairings is of great significance for lexical and syntactic research, lexicography, and IR tasks. The dictionary of lexical constructions matches frames evoked by a particular target word into morphosyntactic patterns. The relevant dataset here is semantic explications (roles), lexico-semantic constrains (e.g. human, emotion, etc.), morphosyntactic constraints on the elements, their syntactic ranks. FrameBank is an offspring project of the Russian National Corpus (http://www.ruscorpora.ru) and involves a large illustrative sample taken from the corpus. The goal of framenet-like corpus annotation is to reveal the diverse realizations of a certain LexCxs in the running text and to mark the elements that correspond to constructional arguments and adjuncts. The corpus part of FrameBank details morphological and syntactic mismatches, violation of lexical and semantic constraints, and focuses on the grammatical constructions that introduce or license the use of elements within a given construction. This is a report on work in progress, which can be followed at http://framebank.ru.
The physiological correlates of variable gradient cycling performance

This study investigates the physiological correlates of computer simulated rolling terrain time-trial performance in a group of competitive cyclists. Twenty eight trained cyclists (age 33 Â± 10 years, body mass 74.4 Â± 7.3 kg, and peak oxygen uptake 64 Â± 7 mL . kg -1. min -1 ) participated in this study. Cyclists initially completed a graded exercise test (GXT) to establish measures of peak power output (PPO), peak oxygen uptake ( O2peak), onset blood lactate accumulation (OBLA), ventilatory threshold (VT) and gross efficiency (GE). On a further occasion cyclists then completed a 20-km time-trial over a computer simulated rolling terrain course from which performance time and mean power output were determined. Pearsonâ€™s correlation (r) was used to examine the magnitude of the relationship between measures in the GXT and time-trial. There were large to very large (r = 0.51-0.9) correlationsÂ between performance time and mean power output in the time-trial and measures of absolute O2peak and PPO from the GXT. Correlations between time-trial performance time and physiological measures were further increased when physiological measures were expressed relative to body mass. The smallest correlations (r < 0.3) were reported between time-trial performance time and mean power output when anaerobic threshold parameters were reported as fractional utilisations of peak power. These findings support the use of body mass corrected variables for predicting performance in rolling terrain time-trials. Cyclists preparing for rolling terrain races are recommended to optimise their power to weight ratio to gain a performance advantage.
Degenerate stochastic differential equations with Hölder continuous coefficients and super-Markov chains

We consider the operator. Formula math. acting on functions in C 2 b (R d + ). We prove uniqueness of the martingale problem for this degenerate operator under suitable nonnegativity and regularity conditions on γ ij and b i . In contrast to previous work, the b i need only be nonnegative on the boundary rather than strictly positive, at the expense of the γ ij and b i being Holder continuous. Applications to super-Markov chains are given. The proof follows Stroock and Varadhan's perturbation argument, but the underlying function space is now a weighted Holder space and each component of the constant coefficient process being perturbed is the square of a Bessel process.
Fuzzy and Adaptive Neuro-Fuzzy Inference System of Washing Machine

Software estimation accuracy is among the greatest challenges for software developers. Fuzzy set theory, Fuzzy system and Neural Networks techniques seem very well suited for typical geotechnical problems. In conjunction with software computing and conventional mathematical methods, hybrid methods can be developed that may prove to be a step forward in modeling geotechnical problems. This study aimed at building two different models, Fuzzy Inference Systems and Adaptive Neuro Fuzzy Inference System and a comparison between them, through an application to real data of the relationship between three inputs (time, temperature of water and the amount of washing powder) during the washing process by using washing machine to get the best result for the cleanness of clothes, where we apply this application at real data. It also provides a natural relationship for combining both numerical information in the form of input/output pairs and linguistic information in the form of If–Then rules in a uniform fashion. The proposed algorithm is achieved by the intelligent system FIS and ANFIS.
The concept of “Neolithic package”: considering its meaning and applicability

In this paper, one of the most frequently used terms in Neolithic studies, e.g. the so-called “Neolithic package”, will be discussed. Apart from providing a brief historical background of the term and how it was used since the 80’s, the text will concentrate on a plausible definition and the possible contents of the package which can be observed as a common set of objects in Southwest Asia, Anatolia and Southeast Europe. It will be argued that the use of this concept has both advantages and disadvantages. Although the term provides a macro level look to the large geography mentioned above, that was obviously closely interconnected in the course of 7th and 6th millennia BC, the term should be implemented cautiously at regions where the elements of the package do not seem to be fully integrated into the life of the groups.
A Secret Sharing Scheme to Recover Secret Unnecessary Calculating

In general, traditional secret sharing threshold schemes require sub stantial computation when recover the secret. This paper represents a secret sharing threshold scheme based on direct partitio ning and combining of set which avoids any computation. This scheme shares the same authority, but different secret shadows, thus extends to general access structures. (w,t) threshold scheme is used to confirm as a special case.
Robust Control of PMSG-based Wind Turbine under Grid Fault Conditions

This paper presents modeling of a direct-driven permanent magnet synchronous generator – based wind turbine and proposes a new controller for Back-To-Back (BTB) converters to enhance Low Voltage Ride Through (LVRT). The LVRT is implemented without any additional devices during grid fault conditions. In this structure, the Proportional-Integral (PI) controllers of Machine Side Converter (MSC) and Grid Side Converter (GSC) are replaced by Sliding Mode (SM) controllers. The MSC controls dc-link voltage and the GSC controls Maximum Power Point Tracking (MPPT) by regulating turbine-generator speed. This control strategy implements different grid code requirements such as Danish grid code. The proposed SM controller in comparison with the PI controller can eliminate dc-link voltage oscillations and reduce the converter voltage and current stresses. Simulation results verify the robustness and effectiveness of the proposed strategy. Hence, by using SM controller, there is no need for additional equipments to enhance LVRT in PMSG-based wind turbines and cost and complexity are significantly reduced.
Optical interprocessor communication protocols

We study routing properties of an optical communication architecture for parallel computing. The building block of the system is a model called the Optical Communication Parallel Computer (OCPC). The units of this computer (processors with local memory) communicate with each other by transmitting messages. A processor can transmit a message to any other processor, and to the same processor neither transmission is successful and retransmission must occur. We also consider a 2-stage processor organization scheme, called the 2-stage OCPC, where processors are organized in a two-dimensional array whose rows and columns consist of OCPCs. The problem that motivated this work is the desire to program these architecture models using high-level, general-purpose, and user-friendly programming languages. The languages should be powerful enough to support features like concurrent memory access, virtual processors, barrier synchronization, and both automatic and explicit memory allocation. Such features are captured by the Parallel Random Access Machine and by Valiant's Bulk-Synchronous Parallel Computer model. Both of these models can be implemented using a certain communication pattern called h-relations. We discuss protocols for realizing h-relations on the OCPC and 2-stage OCPC. The protocols primarily deal with contention resolution since contention in an optical system can inhibit message transmission. <<ETX>>
Sexual dimorphism in cognition and behaviour: the role of X-linked genes

Chimpanzees and humans last shared a common ancestor between 5 and 7 million years ago; 99% of the two species' DNA is identical. Yet, since the paths of primate evolution diverged, there have been remarkable developments in the behavioural and cognitive attainments of our species, which ultimately reflect subtle differences in gene structure and function. These modifications have occurred despite evolutionary constraints upon the diversity of genetic influences, on the development and function of neural tissue. Significant species differences can be observed both at the levels of function (gene expression) and structure (amino acid sequence). Protein evolution is driving an accelerating increase in brain complexity and size. Playing centre stage, in terms of the proportion of genes involved in brain development and cognitive function, is the X chromosome. Recently, it has become clear that a long-standing theory, implicating X-linked genes in a sexually antagonistic evolutionary role, is probably correct. Genes on the sex chromosomes can directly influence sexual dimorphism in cognition and behaviour, independent of the action of sex steroids. Mechanisms by which sex-chromosomal effects, due to X-linked genes, influence neural development or function are reviewed. These include the biased expression of genes subject to X-inactivation. haploin-sufficiency (in males) for non-inactivated genes with no Y homology, sex-specific brain functions and genomic imprinting of X-linked loci. Evidence supporting each of these mechanisms is available from both human and animal models. Recently, the first candidate genes have been discovered.
A novel approach for rapid micropropagation of maspine pineapple (Ananas comosus L.) shoots using liquid shake culture system

Maspine ( Ananas comosus L.) is currently the most preferred pineapple variety in Malaysia due to its pleasant aroma and applicability in caning. Large quantities of plant materials are needed to fulfill the market demand which could not be obtained from the conventional breeding method. Hence, in vitro procedure was developed as an alternative method to improve the multiplication rate of this special variety. Sterilized explants were cultured on solidified Murashige and Skoog (MS) medium supplemented with various combinations of 6-benzylaminopurine (BAP) (1 to 5 mg/l) and ∝-naphthaleneacetic acid (NAA) (1 to 5 mg/l) hormones. Pineapple plant cultures required 5 mg/l BAP to significantly increase the shoot development during the in vitro stage. In addition, explants were subsequently sub-cultured on medium with 1 mg/l BAP which produced highest number of proliferated in vitro plantlets. The optimization of the conditions for shoot propagation was carried out in both liquid and solid medium by supplementing with 1 or 5 mg/l of BAP. MS liquid medium supplemented with 1 mg/l BAP produced the highest number of shoots (31) after 4 weeks. The number of shoots formed was increased to 204 after third sub-culture in liquid medium. Shoot proliferation was increased up to nine-fold in liquid medium when compared to the cultures maintained on solid medium. This improved method of Maspine in vitro multiplication will serve as an alternative source of planting materials of this cultivar for subsistence and large-scale pineapple farmers. Key words : Pineapple, in vitro, 6-benzylaminopurine, ∝-naphthaleneacetic acid, liquid medium.

The Viability of Asset Price Channel Implementation to the Monetary Transmission Mechanism of Ukraine

Monetary transmission mechanism is a key element of the central bank’s activity, where the asset price channel plays an important role among others. Although in Ukraine it is not used. The viability analysis of this channel implementation in the monetary transmission mechanism of Ukraine is executed and the finding about current unavailability for this is made. However, the perspectivity and necessity of asset price channel implementation in the monetary transmission of Ukraine already today requires the creation of theoretic base appropriate for this. Therefore some propositions on the assets price channel implementation in the monetary transmission mechanism of Ukraine are offered.
Electric freight vehicles for urban logistics – technical performance, economics feasibility and environmental impacts

This paper summarises the lessons learned from using electric freight vehicles (EFVs) for urban freight transport in three dimensions. First we look at the technical and operational suitability of using EFVs, including energy efficiency, range and its seasonal variations, and charging and local grid capacity issues. Then we examine all the elements which affect the business case from a carrier’s perspective, including changes of business model by the size of the vehicle, changes in value network and the elements required to enable a transition towards a widerscale electrification. Finally, we present the environmental impacts from running EFVs at three levels, including direct impact analysis from the project demonstration activities, impact analysis at a wider uptake level by using traffic models and impact monetisation. Data used for this analysis is collected under the European FP7 project FREVUE, where around 80 electric-powered vehicles were deployed in the cities of Amsterdam, Lisbon, London, Madrid, Milan, Oslo, Rotterdam, and Stockholm.
A Review on Information Retrieval – Natural Language Processing Approach

Information retrieval is very important area in any of the IT applications. Systematic data storage is essential in information retrieval. In conventional method, data is stored in a structured format and retrieved using SQL queries which requires technical knowledge. Most common data storing and retrieving mechanism in IT is the Relational Database Management Systems. Now there is a necessity to retrieve data from a very large database using natural language from any social media. A brief survey of various methods used to store and retrieve data using Natural Language Processing (NLP) is carried out in this paper.
Non-destructive evaluation of moisture content in wood using ground-penetrating radar

Abstract. This paper presents the results of a series of laboratory measurements, carried out to study how the ground-penetrating radar (GPR) signal is affected by moisture variation in wood material. The effects of the wood fibre direction, with respect to the polarisation of the electromagnetic field, are investigated. The relative permittivity of wood and the amplitude of the electric field received by the radar are measured for different humidity levels using the direct-wave method in wide angle radar reflection configuration, in which one GPR antenna is moved while the other is kept in a fixed position. The received signal is recorded for different separations between the transmitting and receiving antennas. Dielectric constants estimated from direct waves are compared to those estimated from reflected waves: direct and reflected waves show different behaviour when the moisture content varies, due to their different propagation paths.
