LTE radio analytics made easy and accessible

Despite the rapid growth of next-generation cellular networks, researchers and end-users today have limited visibility into the performance and problems of these networks. As LTE deployments move towards femto and pico cells, even operators struggle to fully understand the propagation and interference patterns affecting their service, particularly indoors. This paper introduces LTEye, the first open platform to monitor and analyze LTE radio performance at a fine temporal and spatial granularity. LTEye accesses the LTE PHY layer without requiring private user information or provider support. It provides deep insights into the PHY-layer protocols deployed in these networks. LTEye's analytics enable researchers and policy makers to uncover serious deficiencies in these networks due to inefficient spectrum utilization and inter-cell interference. In addition, LTEye extends synthetic aperture radar (SAR), widely used for radar and backscatter signals, to operate over cellular signals. This enables businesses and end-users to localize mobile users and capture the distribution of LTE performance across spatial locations in their facility. As a result, they can diagnose problems and better plan deployment of repeaters or femto cells. We implement LTEye on USRP software radios, and present empirical insights and analytics from multiple AT&T and Verizon base stations in our locality.
Scalable Cluster Computing with MOSIX for LINUX

Mosix is a software tool for supporting cluster computing. It consists of kernel-level, adaptive resource sharing algorithms that are geared for high performance, overhead-free scalability and ease-of-use of a scalable computing cluster. The core of the Mosix technology is the capability of multiple workstations and servers (nodes) to work cooperatively as if part of a single system. The algorithms of Mosix are designed to respond to variations in the resource usage among the nodes by migrating processes from one node to another, preemptively and transparently, for load-balancing and to prevent memory depletion at any node. Mosix is scalable and it attempts to improve the overall performance by dynamic distribution and redistribution of the workload and the resources among the nodes of a computing-cluster of any size. Mosix conveniently supports a multi-user time-sharing environment for the execution of both sequential and parallel tasks. So far Mosix was developed 7 times, for different version of Unix, BSD and most recently for Linux. This paper describes the 7-th version of Mosix, for Linux.
Age, gender, ethnicity and the digital divide: university students’ use of web‐based instruction

This paper focuses on the effects of social–structural factors (age, ethnicity and gender) on university students’ use of web‐based instruction. The study uses data from registration questionnaires of students at the Open University of Israel. During the period between 1995 and 2002 there has been a continuous increase in the proportion of students who use the Internet and email for study purposes. However, a significant minority (one‐third of the students) are still not Internet users. Previous studies have referred to the digital divide in terms of differences in access to the relevant hardware and explained it mainly by social and structural factors. Current research tends to focus on the digital divide in terms of use rather than access, and explains it mainly by micro, individual and situational characteristics. The present study shows that structural factors such as age, gender and ethnicity also play a significant role in the continuous existence of the usage gap. The social and educational implications of this gap are discussed.
Connectionist Models and Their Properties

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise-sensitivity, distributed decision-making, time and sequence problems, and the representation of complex concepts.
Technology in the classroom: steps toward a new vision

The history of technology in the classroom is one of cycles of exaggerated promises, highly publicised installations with committed teachers, and masterful and inventive excuses for why the promises went unfulfilled. But in spite of this history there is a new vision of technology in schooling emerging, thanks to the World Wide Web. This vision can be seen especially in schools that have used technology as a lever to achieve school‐wide reform in teaching and learning. The present study is based on 94 case studies of successful school reforms where information and computer technologies (ICT) were also heavily used. The studies, done in the 1999–2000 school year across 23 countries, were all case studies, organised around five central hypotheses. These hypotheses tested whether ICT acted as a catalyst for school reform, how ICT diffused throughout the school, what the key elements were for successful implementation of ICT, whether ICT use resulted in further inequities in schooling, and what happened to academic standards when ICT was heavily implemented. From the innovations and ICT uses in the schools studied, a vision of how ICT can assist with a transformation of K‐12 schooling can be discerned. By expanding the time and space of schooling, opening the classroom to the outside world, forming communities of learners, parents and teachers, and by giving all schools access to an expanding world of resources, both teaching and learning can be advanced to a new level of effectiveness and social importance.
Evaluation of the Length Distribution of Needle Thread within the Take-up Disc Zone of a Lockstitch Machine

Evaluation of the length distribution of needle thread during stitch formation is necessary to determine the dynamic characteristics of a sewing machine, and the thread needed in this process. In this study, physical and mathematical models of the take-up disc are developed. The thread length for the full rotation range is determined as the geometrical distance between the active frictional barriers. The algorithm of calculations is introduced and implemented alternatively by means of the languages Fortran and C++, as well as by genetic algorithms. The length distribution of the needle thread obtained was verified by using simulations of the sequence and geometry of the frictional barriers, as well as experimental research of the purpose-oriented model of the take-up disc prototype.
Effective Admission Policy for Multimedia Traffic Connections over Satellite DVB‐RCS Network

Thanks to the great possibilities of providing different types of telecommunication traffic to a large geographical area, satellite networks are expected to be an essential component of the next‐generation internet. As a result, issues concerning the designing and testing of efficient connection‐admission‐control (CAC) strategies in order to increase the quality of service (QoS) for multimedia traffic sources, are attractive and at the cutting edge of research. This paper investigates the potential strengths of a generic digital‐video‐broadcasting return‐channel‐via‐satellite (DVB‐RCS) system architecture, proposing a new CAC algorithm with the aim of efficiently managing real‐time multimedia video sources, both with constant and high variable data rate transmission; moreover, the proposed admission strategy is compared with a well‐known iterative CAC mainly designed for the managing of real‐time bursty traffic sources in order to demonstrate that the new algorithm is also well suited for those traffic sources. Performance analysis shows that, both algorithms guarantee the agreed QoS to real‐time bursty connections that are more sensitive to delay jitter; however, our proposed algorithm can also manage interactive real‐time multimedia traffic sources in high load and mixed traffic conditions.
Is the Cultural Cringe Alive and Kicking? Adolescent Mythscapes of Australian English in Queensland and Victoria

Although there is a growing literature on grammatical, lexical and phonological aspects of Australian English, there are comparatively few studies of attitudes towards this variety of English. What literature there is tends to be either anecdotal or based on media language or on findings from experimental, subjective reaction tests where samples of speech are matched against those produced by speakers of other varieties of English. This study aims to add to existing research through an examination of responses of Australian adolescents to the following question: ‘When you think about “Australian English”, tell me the first three things that come into your mind’. The findings fall into three broad overlapping categories: (i) comments about language features; (ii) comments about attitudes towards those features; and (iii) comments about culture. All three categories contain responses which suggest that young Australians associate Australian English with rural and informal lifestyles. Those who provide attitudinal judgments either describe the variety in neutral terms or give it evaluations typical of those reported for broad and vernacular varieties of English. Of particular interest is the frequency with which categories overlap and intersect, and the mythscapes they construct of Australian language and identity.
Validation of the Simple View of Reading in Hebrew—A Semitic Language

The Simple View of Reading (SVR) in Hebrew was tested by administering decoding, listening comprehension, and reading comprehension measures to 1,002 students from Grades 2 to 10 in the northern part of Israel. Results from hierarchical regression analyses supported the SVR in Hebrew with decoding and listening comprehension measures explaining much of the variance in reading comprehension. Further, commonality analyses showed that decoding and listening comprehension contributed differently at different grade levels with decoding generally contributing more at the early grade levels and listening comprehension contributing more at the higher grade levels, which is observed in other alphabetic languages as well. However, unlike in transparent orthographies, such as Spanish and Finnish, decoding seems to play an important role in reading comprehension for a longer period due to the nature of Hebrew orthography of using unpointed script after the fourth-grade level.
Personality Differences between Prisoners and Controls

2,070 male prisoners and 2,442 male controls were administered the Eysenck Personality Questionnaire, which gives scores on Psychoticism, Extraversion, Neuroticism, and Lie scales. The groups were subdivided into age groups, ranging from 16 to 69 yr. at the extremes. It was found that the Lie scale disclosed little dissimulation in either group. Scores on Psychoticism, Extraversion, and Neuroticism fell with age for both prisoners and controls. Prisoners had higher scores than controls, as predicted, on all three scales. It is concluded that prisoners show predictable differences in personality as compared with controls.

The study was undertaken to determine the prevalence diseases in commercial chickens in Sylhet region of Bangladesh. Among the diseases prevalence of infectious bursal disease (IBD) is higher (22%) followed by colibacillosis (14.03%), Newcastle disease (ND) (13.84%), salmonellosis (12.18%), chronic respiratory disease (CRD) (11.66%), coccidiosis (7.87%), aspergillosis (7.2%), omphalitis (5.31%), fowl cholera (2.70%), fowl pox (0.28%), nutritional deficiency (0.23%), lymphoid leucosis (0.14%) and some mixed infections like salmonellosis plus E. coli (1.14%), IBD plus coccidiosis (0.71%), ND plus colibacillosis (0.71%). According to the age groups, disease prevalence was recorded as 33.41% among the age group of 21-35 days followed by 8-20 days age group (21%), 61- above days age group (17.49%), 36-60 days age group (15.92%) and 0-8 days age group (12.18%) of commercial chickens. The distribution and proportionate occurrence of diseases in chickens of Bangladesh indicated that the diseases frequently occurred in summer season (39.85 %) followed by winter (32.80%) and rainy season (27.35%).
Plots of electric field strength in biological tissue irradiated with slot type MW irradiator

The electric field caused by a slot type MW irradiator is pictured and analyzed. It is shown that in the direction normal to the slot irradiator the electric field is spread far from the edge of the irradiator, and in the direction along the slot the field is concentrated near the central part of the irradiator and does not spread much beyond the edge of the irradiator.
Probabilistic Neural Network Based Islanding Detection in Distributed Generation

Abstract This article proposes a probabilistic neural network based islanding detection technique for distributed generation considering multiple parameters in order to secure the detection of islanding for any possible network topology. This approach utilizes different parameters (features), such as rate of change of frequency, rate of change of voltage, rate of change of power, rate of change of frequency over power, total harmonic distortion (current), and rate of change of power factor, derived at the target distributed generation location and fed to the probabilistic neural network for automatic islanding detection. While comparing with other techniques, such as the radial basis function neural network and decision tree, the probabilistic neural network based technique is found to be highly effective in islanding detection. The proposed algorithm has been tested for simulation model, as well as the real-time digital simulator, and results indicate that the proposed method can reliably detect islanding conditions in the power distribution network with multiple distributed generation interface.
Die Einrichtung von Einzelzimmern auf neonatologischen Intensivstationen – Auswirkungen auf die Betreuung aus Sicht der Eltern

Zusammenfassung Hintergrund: Das Konzept der Versorgung neonatologischer Patienten in Einzelzimmern wird bisher in keiner deutschen Klinik konsequent umgesetzt. Untersuchungen aus anderen Ländern zeigen sowohl Vor- als auch Nachteile für das Personal, die Patienten und deren Familien. Ziel einer Befragung war es, die Auswirkungen des Raumkonzeptes auf die Betreuung der Kinder im Vergleich zur Versorgung im Mehrbettzimmer aus Sicht betroffener Eltern zu erfassen. Methodik: Befragung der Eltern von Patienten einer deutschen neonatologischen Abteilung mittels standardisiertem Fragebogen und Vergleich der Ergebnisse mit international durchgeführten Untersuchungen. Ergebnisse: Deutliche Verbesserungen wurden im Einzelzimmer hinsichtlich der Ermöglichung familiärer Privatsphäre, des Datenschutzes und der Reduzierung störender Umwelteinflüsse auf die sensiblen Patienten wahrgenommen. Als negative Auswirkung erwies sich die erschwerte Kontaktaufnahme zu anderen betroffenen Eltern während des stationären Aufenthaltes. Die Ergebnisse spiegeln weitgehend die Erkenntnisse internationaler Studien wider. Diskussion: Durch die Einrichtung von Einzelzimmern auf neonatologischen Intensivstationen wird aus Sicht der Eltern die Versorgung der Patienten überwiegend verbessert. Die veränderten räumlichen Gegebenheiten können ein in der Abteilung implementiertes Konzept der entwicklungsfördernden und familienzentrierten Betreuung ergänzen.
Economic values of the APCN multi‐model ensemble categorical seasonal predictions

The skill of seasonal mean precipitation and temperature predictions by multi‐model ensemble (MME) schemes has been examined using hindcast data from the APEC Climate Network (APCN). The hindcast data of the member models have been collected from several institutions in the APEC region. Skill metrics, namely, anomaly correlation coefficient (ACC), Hanssen‐Kuipers skill (HKS), and economic value were used to assess the APCN MME predictions. The member models have a range of skills in predicting the seasonal mean conditions: however, the MME schemes consistently produce improved predictions. Though the weighted multi‐model ensemble schemes have better skill scores in terms of ACC, the unbiased multi‐model ensemble mean provides better and more useful categorical predictions as seen from the HKS score and the economic values. Prediction skills show distinct seasonality in different regions. Precipitation prediction skill is the lowest in the Asian monsoon region in June‐July‐August. The APCN MME predictions have positive economic values in most regions and examination of monthly values suggests that the MME predictions are reasonably good and useful even with three‐month lead times. An uncalibrated multi‐model probabilistic prediction scheme gives an indication of threshold probability for which the seasonal predictions are more beneficial to users. The extreme climatic conditions are predicted well by the MME schemes. However, user sectors for which the extreme climate predictions are beneficial are different to those of regular three‐category predictions. These results can be used in planning and preparedness for the extremes of climate in the future, and when developing economic decision support models. Copyright © 2006 Royal Meteorological Society
A low-power integrated circuit for remote speech recognition

In this paper, a low-power, low-voltage speech processing system is presented. The system is intended to he used in remote speech recognition applications where feature extraction is performed on terminal and high-complexity recognition tasks and moved to a remote server accessed through a radio link. The proposed system is based on a CMOS feature extraction chip for speech recognition that computes 15 cepstrum parameters, each 8 ms, and dissipates 30 /spl mu/W at 0.9-V supply. Single-cell battery operation is achieved. Processing relies on a novel feature extraction algorithm using 1-bit A/D conversion of the input speech signal. The chip has been implemented as a gate array in a standard 0.5-/spl mu/m, three-metal CMOS technology. The average energy required to process a single word of the TI46 speech corpus is 10 /spl mu/J. It achieves recognition rates over 98% in isolated-word speech recognition tasks.
Aspects of melting and the radar bright band

The melting of snow as it falls through the 0 °C level is a significant meteorological process that is important for its impact as the bright band of enhanced reflectivity in radar observations. Thus, it is necessary to understand the variability of the phenomena and to determine the factors upon which it depends. This paper reports on preliminary investigations into the observations of the bright band over the UK using vertically pointing radar. These results are compared with output from a simple model of the melting of snowflakes and with other observations from Canada and the Netherlands. The vertical depth of the bright band was determined from the vertical pointing radar data for four cases of widespread frontal rainfall. An increase in the depth of the bright band was seen with increasing background reflectivities. Depths of 100–150 m at 10 dBZ increased to 200–400 m at 25 dBZ. Results from a simple model of the melting of snowflakes were compared with the vertical pointing radar observations. Similar trends were seen in the model output, but in general the model produced deeper but less intense bright bands. Notable in the model results was the lack of strong dependence of the depth on vertical air motions. Indeed, the bright band depth only increased by approximately 30 m in a downdraft of 1 m s−1. Comparisons of the bright band characteristics with other observations from elsewhere show that the bright band depth was similar to that observed by Klaasen (1988) in the Netherlands, but shallower than those observed by Fabry & Zawadski (1995) in Canada.

Cervical Epidural Blockade: A Technique in Disuse or Alternative to Other Techniques

Regional anesthesia has a wide area of choices, especially when selecting the surgical procedure to be performed, either elective or emergency. Applied neck surgeries, upper limbs (brachial plexus in its entirety) and thoracic surgery and anesthesia, analgesia or in combination with general anesthesia, depending on the needs. The cervical epidural technique is a procedure that is not regularly because of ignorance and lack practical training in medical units residence, have left for fear of complications that could be catastrophic in inexperienced hands [1]. With the advent of technology tools such as ultrasound neurostimulator and they have moved this technique considered risky compared to previous ones. However, although some studies in the literature with excellent results, complications from this procedure are low are not reported [2,3]. And the knowledge of anatomy and physiological changes of this technique to be well recognized even know it is much safer than others, which reports frequent complication because their approaches are: Robert M. Raw makes an exemplary description regarding the technique.
Learners’ interactions: a comparison of oral and computer-assisted written conversations

Previous research has underscored the role of negotiation in providing appropriate conditions for second language acquisition. Varonis and Gass (1985b), in a study of English as a Second Language (ESL), found greater amount of negotiation in non-native–non-native interaction than in native-non–native interaction. Given the increased interest in computer mediated communication and in its applications to language learning, this investigation explores whether those results are obtained when using an electronic written medium. This study compared the negotiations generated by dyads of non-native speakers (NNS–NNS), native speakers (NS–NS), and non-native and native speakers (NNS–NS), in the oral and written modes. The results revealed that the NNS–NS group negotiated in the oral mode significantly more than in the written mode; this group also negotiated significantly more than the other two groups in the oral mode. Learners' shared social and linguistic background seemed to have facilitated the comprehension of input. Conversely, lack of familiarity with native speaker's pronunciation seemed to have caused more breakdowns in the oral conversations of the mixed dyads. Though the results of this study suggest that negotiation is not the main resource to obtain modified input in a foreign language context, other learning strategies that may be beneficial in the language learning process were at use in learner-learner interaction.
Routine Contraction in Good Times: An Example of a Typical Prototype Development Routine

In this study, I questioned the general wisdom in the routine literature that routine contraction happens only as a response to adverse situation. I empirically examined routine contraction in a metaphorical context of SCRABBLE® played in the National SCRABBLE® Championship, 2010. Here, each SCRABBLE® routine is an analogy of a prototype development routine. The results indicate that the performance of a routine at time t0 positively affects contraction of the routine at time t1. This relationship is negatively moderated by the efficiency of the routine. Therefore, routine contraction does not necessarily imply that “all is not well” with the routine.
