What determines duration-based rhythm measures: text or speaker?

Differences in rhythm between languages have been often attributed to differences in phonological properties such as syllable structure. This paper uses quantitative analyses to determine whether and how popular duration-based rhythm measures depend on the phonological structure of a language. Native speakers of five languages read a large corpus of comparable texts (approximately 371,000 syllables in total). Phonological properties of each language were speci- fied as 11 variables, computed from the phonetic transcriptions. These variables were compared against published rhythm measures that captured variation in duration of consonantal and vocalic intervals. While the text-based measures dis- criminated well between languages, the values of rhythm measures overlapped substantially, showing that the languages are more alike in acoustic implementa- tion than in their phonological description. Multilevel models demonstrated that the mapping between phonological properties and acoustics is much weaker than previously assumed: linear effects of the phonological variables explained less than a quarter of the total variance in rhythm measures. Instead, speaker was the main source of variation in those measures. Rhythm, in the sense of dura- tional variability, depends far more on individual timing strategies than on the phonological structure of a language.
Learners on the move: mobile modalities in development studies

Many careers involve mobile lifestyles, yet require specialised postgraduate qualifications for career progression. Mobile technologies offer new opportunities by providing more choice in when, where, and how students learn. Experiences in an Australian postgraduate development studies program illustrate the choices. Three key issues are explored: the implications of variable Internet access and quality; how students use their mobile devices; and how mobile learning allows consistent engagement with peers, despite geographical, cultural, or socio‐political isolation. The outcomes demonstrate that mobile technologies offer opportunities for ongoing access to distance education that can be pursued off‐campus and transnationally with the same peer‐centred approaches available on‐campus, enhancing authenticity of both content and context. Offline, laptop computers and digital audio players provide portable lecture theatres, libraries, and study areas, while online they offer discussion spaces, research portals, and simulation environments. Mobile learners stand to benefit from the expanding access offered by new technologies, but the spotlight must remain firmly on pedagogical intentions rather than on delivery modes.
Intrusion Detection System for High Volume and High Velocity Packet Streams: A Clustering Approach

 Abstract—The success of any Intrusion Detection System lies in its ability to quickly adapt to new threats in near real time and further prevent new attacks. This implies extremely efficient machine learning algorithms in the backend, which in turn may use clustering algorithms capable of distinguishing between normal and anomalous network traffic. This work is a first step towards proposing such an IDS, which is built on clustering-based machine learning. The authors evaluate different clustering algorithms using a network packet trace and provide results, which help in evaluating these algorithms. The work-in-progress section of the paper visualizes the IDS which can be used in an environment where the traffic volumes are very high, enterprise boundaries are blurred, and the likelihood of malicious attacks is extremely high.
Research and Theoretical Considerations in Authority Control

Research and recent "theoretical" discussions of authority control are synthesized and organized into the following groups: general overviews; need for research; need for unique access points for names; need for authority control outside traditional library catalogs; reference structure for names and its relationship to users' needs; authority control for works; authority control for subjects; need for authority files; and, technological considerations. Conclusions are drawn about the need for research in the area of file design.
A 300fps Progressive Scan HDTV High Speed Camera

We have developed an HDTV (High-definition television) high speed camera that uses three 2.2 M-pixel complementary metal oxide semiconductor image devices. The camera enables image acquisition up to a maximum speed of 300 frames per second and stores the image sequences directly in a semiconductor memory chip in the camera head. High-quality slow motion playback is available as the image is stored without being compression. A compact, lightweight (7.7 kg), handheld camera head can be controlled from a camera control unit using a single standard HDTV hybrid fiber optic camera cable (Max. 2 km).
A three phase regulated PWM rectifier using direct on-line feedforward input unbalance correction control

The analysis and design of a direct six-switch three-phase PWM rectifier, capable of correcting input unbalance, is presented. Based on the input source positive and negative sequence components, an unbalanced transfer matrix in-terms of input phase voltages is derived. An online method is used to implement the transfer matrix function and generate the switch gating signals. As compared to other unbalance correction methods the proposed approach is very simple to implement. It uses a minimum of discrete analog and digital components. The algorithm of the proposed approach is described, and experimental results from a 1 kVA breadboard are provided for verification. <<ETX>>
A production ready, 6-18-GHz, 5-b phase shifter with integrated CMOS compatible digital interface circuitry

A producible, high-yield, monolithic 6-18-GHz, 5-b phase shifter with integrated standard CMOS compatible digital interface circuitry has been developed for use over the -55 to +90 degrees C temperature range. Differential phase shift is achieved using high-pass and low-pass filter structures. The integrated digital interface circuitry produces complementary outputs that are used to bias the phase-shifter bits. The integration of the digital interface circuitry, made with microwave FETs, reduced the phase-shifter bit control bias lines by a factor of 2. The phase shifter was fabricated at both Raytheon's and Texas Instruments' GaAs foundries in production quantities using a standard microwave process. Complete on-wafer RF tests were performed to screen the phase-shifter circuits and determine electrical yield. The phase shifter has an r.m.s. phase error >

Windows Malware Detection Method Based on the Path IRP

Because the IRP (I/O Request Packets) sequences of programs are not identical in different environments in the same operating system, which have a certain influence on the detection results. Through a lot of experiments, we found that the IRP request sequences of programs on the same operation path are consistent. Therefore, the new malware detection method based on the path IRP sequences is proposed. Every single IRP request sequence on the same operation path is extracted, Negative Selection Algorithm (NSA) and Positive Selection Algorithm (PSA) are used for detection. Experimental results reveal that our method outperforms the method which based on IRP sequences in detection rate.
International Symposium on Intelligent Manufacturing and Automation , DAAAM 2014 Classification of Test Documents Based on Handwritten Student ID ’ s Characteristics

The bag of words (BoW) model is an efficient image representation technique for image categorization and annotation tasks. Building good feature vocabularies from automatically extracted image feature vectors produces discriminative feature words, which can improve the accuracy of image categorization tasks. In this paper we use feature vocabularies based biometric characteristic for identification on student ID and classification of students' papers and various exam documents used at the University of Mostar. We demonstrated an experiment in which we used OpenCV as an image processing tool and tool for feature extraction. As regards to classification method, we used Neural Network for Recognition of Handwritten Digits (student ID). We tested out proposed method on MNIST test database and achieved recognition rate of 94,76% accuracy. The model is tested on digits which are extracted from the handwritten student exams and the accuracy of 82% is achieved (92% correctly classified digits). © 2015 The Authors.

Implementation of an Application for Intrusion Detection on Network Virtual Machine

Al giorno d’oggi, i sistemi per il rilevamento delle intrusioni, comunemente detti IDS, dall’inglese Intrusion Detection System, costituiscono un componente essenziale delle reti di computer. Infatti, la diffusione delle connessioni ad Internet causa un continuo aumento del numero di utenti e servizi, con il risultato che la quantita di lavoro che deve essere svolto da un IDS aumenta giorno dopo giorno, e gli IDS devono migliorare le proprie prestazioni altrettanto costantemente. Dato che siamo ormai arrivati ad un punto in cui e difficile migliorare ulteriormente questi programmi per quanto riguarda il software, gli ultimi sforzi nel campo sono stati orientati verso l’implementazione in hardware degli IDS, o almeno delle loro parti computazionalmente piu intensive. Il passaggio non e scontato, dato che il riutilizzo di codice preesistente non e facilmente realizzabile, a causa delle enormi diversita che presenta l’hardware in commercio, sia per quanto riguarda l’architettura, che per quanto riguarda il metodo di programmazione. Spesso, la soluzione piu pratica e quella di ricominciare il lavoro da capo, “reinventando la ruota” per ogni dispositivo. Il framework NetVM, sviluppato al Politecnico di Torino, ha come scopo la risoluzione di questo problema. Attraverso l’astrazione di un network processor e la definizione di un set di istruzioni molto specifico, orientato al processamento di pacchetti, si propone di ottenere la portabilita del codice su un buon numero di dispositivi hardware e software, pur mantenendo alta l’efficienza.
Modeling Local Segregation: A Spatial Interaction Approach

Most measures of residential segregation can be regarded as global measures because they are summary indices for the entire study region. But the level of segregation is not uniform within the region and therefore local measures are warranted. The entropy-based diversity index is a local measure, but it fails to account for interactions between population groups across areal boundaries. In this paper, the diversity index is modified to accommodate spatial interaction between population groups across areal units. In addition, a set of local segregation measures is introduced to model local segregation based upon the exposure concept in segregation studies and the spatial interaction concept in geographical modeling. A simulation and an empirical study are used to demonstrate the utilities of this modeling approach.
Masked morphological priming of compound constituents

Recent masked priming studies suggest that complex words are rapidly segmented into potential morphological constituents during initial visual word recognition. Much of this evidence involves affixation or other formally regular operations, leaving open the question of whether these effects rely heavily on the identification of a closed-class affix or other formal regularity. In two masked priming experiments with English transparent and opaque bimorphemic compound primes consisting solely of open-class morphemes, we find significant constituent priming, but no significant priming for purely orthographic overlap. We conclude that masked morphological priming generalizes across word-formation types to include compounds with no affix or other regular form. These results provide new evidence for across-the-board morphological-level segmentation during visual word recognition and for morpheme-based compound processing.
ATOMIC BROADCAST: FROM SIMPLE MESSAGE DIFFUSION TO BYZANTINE AGREEMENT

In loosely coupled distributed systems subject to random communication delays and component failures, atomic brocrdcart protocols can be used to implement the abstraction of a A-common sfomge, a replicated storage that displays at any clock time the same contents to every correct processor and that requires A time units to complete replicated updates. We term a broadcast protocol atomic if (1) it delivers every message broadcast by a correct sender to all correct receivers within some known time bound (ferminution), (2) it ensures that every message whose broadcast is initiated by a sender is either delivered to all correct receivers or to none of them (ofomicify), and (3) it guarantees that all delivered messages from all senders are delivered in the same order at all receiving nodes (order). This paper presents a famib of atomic broadcast protocols that are tolerant of increasingly general fault classes: ommm fuulfs, which cause a component (processor or communication link) never to deliver a requested service, riming fuulfs, which cause a component to deliver a requested service either too early or too late, and Byanfine fuults, which lead to the delivery of a service other 'than the one requested. The protocols work for arbitrary point-to-point network topologies, can tolerate any number of faults up to network partitioning, use a small number of messages, and achieve in many wes the best possible termination times.
The Expression of Time in Tibeto-Burman

This paper studies the syntax of three Tibeto-Burman languages as it is related to the expression of time. The languages are Nusu, Anung, and rGyalrong (Jiarong). They are among the non-Sinitic languages that I have done field research on during the past ten years. The first two languages are spoken along the Nu River valley in northwestern Yunnan, China. Nusu, with its simple inflectional system, is generally classified with the Yi-Mian or Lolo-Burmese branch of TB, while Anung is a close kin of Dulong (Trung, Rawang) and belongs to the Rungish group. rGyalrong is a TB language spoken in Sichuan. The name rGyalrong also refers to a group. rGyalrong has been classified as a sub-branch of the Qiangic stock because these languages share more typological features with each other than with any other TB branch, though it is possible that rGyalrong may turn out to deserve a separate place from Qiang. The rGyalrong variety being considered here is the eastern Situ dialect.
Novel algorithm by low complexity filter on retinal vessel segmentation

This article shows a new method to detect blood vessels in the retina by digital images. Retinal vessel segmentation is important for detection of side effect of diabetic disease, because diabetes can form new capillaries which are very brittle. The research has been done in two phases: preprocessing and processing. Preprocessing phase consists to apply a new filter that produces a suitable output. It shows vessels in dark color on white background and make a good difference between vessels and background. The complexity is very low and extra images are eliminated. The second phase is processing and used the method is called Bayesian. It is a built-in in supervision classification method. This method uses of mean and variance of intensity of pixels for calculate of probability. Finally Pixels of image are divided into two classes: vessels and background. Used images are related to the DRIVE database. After performing this operation, the calculation gives 95 percent of efficiency average. The method also was performed from an external sample DRIVE database which has retinopathy, and perfect result was obtained
Research on Domain Ontology-Based Concept Similarity Calculation

Similarity computing of ontological concept has made rapid progress in the field of data mining, information processing and artificial intelligence and becoming one of the hot research field of information technology, particularly the idea of the semantic Web was proposed in 2000, the concept of semantic similarity has gotten more attention, while also facilitating its further development and application in information retrieval. Considering the deficiencies of existing concept similarity algorithm, this paper design the method to reduce the candidate set of domain concept, and put forward a similarity calculation model based on the concept name, instances, properties, and semantic structure of domain ontology. Integrated several main influencing factors, the experiments show the proposed algorithm can express the impact of various factors on the similarity in the calculation concept similarity of domain ontology. By comparing with the traditional similarity method and expertise experience value, the experiment result shows that the effectiveness and correctness of the concept similarity calculation model.
Which Comes First the Simulation or the Lecture?

Research into the instructional effectiveness of computer-based simulations has yielded inconsistent results. Part of this inconsistency can be attributed to the inappropriate instructional roles for which simulations are used. Two of the most promising roles of simulations in instruction are to: 1) establish a cognitive framework or structure to accommodate further learning in a related subject area, and 2) provide an opportunity for reinforcing, integrating and extending previously learned material. Thus, the effectiveness of a given simulation may depend upon when it is administered within an instructional sequence. The purpose of these two studies was to: 1) ascertain the value of a particular simulation to the learning of genetics principles, and 2) determine whether the position of the simulation, within the sequence of instructional events, altered its effectiveness. In both studies, students receiving the stimulation as a framework for understanding prior to formal classroom instruction scored significantly higher on an applications posttest than did students using the simulation as an integrating activity following formal instruction. Both groups scored higher than a control group which did not use the simulation prior to the posttest.
Vision-Based Detection and Tracking of a Mobile Ground Target Using a Fixed-Wing UAV

This paper presents a framework for tracking a mobile ground target (MGT) using a fixed-wing unmanned aerial vehicle (UAV). Challenges from pure theories to practical applications, including varying illumination, computational limits and a lack of clarity are considered. The procedure consists of four steps, namely: target detection, target localization, states estimation and UAV guidance. Firstly, the MGT in the wild is separated from the background using a Laplacian operator-based method. Next, the MGT is located by performing coordinate transformations with the assumption that the altitude of the ground is invariant and known. Afterwards, a Kalman filter is used to estimate the location and velocity of the MGT. Finally, a modified guidance law is developed to guide the UAV to circle and track the MGT. The performance of our framework is validated by simulations and a number of actual flight tests. The results indicate that the framework is effective and of low computational complexity, and in particular our modified guidance law can reduce the error of the tracking distance by about 75% in specified situations. With the proposed framework, such challenges caused by the actual system can be tackled effectively, and the fixed-wing UAV can track the MGT stably.
The CSIRO Mk3L climate system model version 1.0 – Part 1: Description and evaluation

Abstract. The CSIRO Mk3L climate system model is a coupled general circulation model, designed primarily for millennial-scale climate simulations and palaeoclimate research. Mk3L includes components which describe the atmosphere, ocean, sea ice and land surface, and combines computational efficiency with a stable and realistic control climatology. This paper describes the model physics and software, analyses the control climatology, and evaluates the ability of the model to simulate the modern climate. Mk3L incorporates a spectral atmospheric general circulation model, a z-coordinate ocean general circulation model, a dynamic-thermodynamic sea ice model and a land surface scheme with static vegetation. The source code is highly portable, and has no dependence upon proprietary software. The model distribution is freely available to the research community. A 1000-yr climate simulation can be completed in around one-and-a-half months on a typical desktop computer, with greater throughput being possible on high-performance computing facilities. Mk3L produces realistic simulations of the larger-scale features of the modern climate, although with some biases on the regional scale. The model also produces reasonable representations of the leading modes of internal climate variability in both the tropics and extratropics. The control state of the model exhibits a high degree of stability, with only a weak cooling trend on millennial timescales. Ongoing development work aims to improve the model climatology and transform Mk3L into a comprehensive earth system model.
Effect of Orostachys japonicus on Apoptosis and Autophagy in Human monocytic leukemia Cell line THP-1 via Inhibition of NF-κB and Phosphorylation of p38 MAPK

Objectives: Orostachys japonicas (O. japonicus) has been known for its anti-tumor effect. In the present study, it was investigated whether O. japonicus EtOH extracts could induce apoptosis and autophagy which are part of the main mechanism related to anti-tumor effect in THP-1 cells. Methods: Cells were treated with various concentrations of O. japonicus EtOH extracts (0-300μg/ml) for 24, 48, and 72h. Cell viability was evaluated by MTS/PMS assay and apoptosis rate was examined by flow cytometry and ELISA assay. The mRNA expression of apoptosis-related genes (Bcl-2, Mcl-1, Survivin, Bax) and autophagy-related gene (mTOR) was evaluated using real-time PCR. The protein expression of Caspase-3, Akt, LC3II, Beclin-1, Atg5, NF-κ B, p38, ERK was evaluated using western blot analysis. Results: O. japonicus EtOH extracts inhibited cell proliferation and apoptosis rate was increased in both flow cytometry and ELISA assay. Bcl-2, Mcl-1, Survivin (anti-apoptosis factors) mRNA expressions were decreased and Bax (pro-apoptosis factor) mRNA level was increased. mTOR mRNA expressions was decreased and LC3II protein expressions was increased. Activation of NF-κB was decreased and phosphorylation of p38 was increased. Conclusion: O. japonicus is regarded to inhibit cell proliferation, to induce apoptosis and to regulate autophagy-related genes in THP-1 cells via NF-κB and p38 MAPK signaling pathway. This suggests O. japonicus could be an effective herb in treating acute myeloid leukemia.
