STRUCTURED PRIORITY QUEUE WITH BATCH ARRIVALS

This paper investigates a single-server priority queueing system with batch arrivals where an arriving batch is composed of multi-class customers. The main motivation for studying this type of priority queue is its potential applicability to communication switching systems. Preemptive resume and nonpreemp­ tive (head-of-the-line) rules are considered. The queue length and waiting time distributions are obtained via the supplementary variable technique and delay cycle analysis. The conservation law approach is applied to find the mean delay formulas.
Efficient Buffering and Scheduling for a Single-Chip Crosspoint-Queued Switch

The single-chip crosspoint-queued (CQ) switch is a compact switching architecture that has all its buffers placed at the crosspoints of input and output lines. Scheduling is also performed inside the switching core and does not rely on latency-limited communications with input or output line-cards. Compared with other legacy switching architectures, the CQ switch has the advantages of high throughput, minimal delay, low scheduling complexity, and no speedup requirement. However, the crosspoint buffers are small and segregated; thus, how to efficiently use the buffers and avoid packet drops remains a major problem that needs to be addressed. In this paper, we consider load balancing, deflection routing, and buffer pooling for efficient buffer sharing in the CQ switch. We also design scheduling algorithms to maintain the correct packet order even while employing multi-path switching and resolve contentions caused by multiplexing. All these techniques require modest hardware modifications and memory speedup in the switching core but can greatly boost the buffer utilizations by up to 10 times and reduce the packet drop rates by one to three orders of magnitude. Extensive simulations and analyses have been done to demonstrate the advantages of the proposed buffering and scheduling techniques. By pushing the on-chip memory to the limit of current ASIC technology, we show that a cell drop rate of 10-8, which is low enough for practical uses, can be achieved under real Internet traffic traces corresponding to a load of 0.9.

Spatio-temporal analysis of the exposure of motorists to submersions of roads due to flash floods in the Gard region

Flash floods are considered as one of the most deadly natural disasters due to their short temporal scales that leave little time for exposed people to response. Recent studies have shown that almost half of the victims are vehicle-related and so daily mobility becomes an important factor which affects social exposure to flash flooding. This report presents the results of understanding and exploiting the potentialities of MobRISK – an activity-based mobility model used to simulate motorists’ exposure in flash flood events by integrating mobility adaptation behaviors with environmental perturbations. The first application of the model is conducted in the Ales area of the Gard department in southern of France for the flash flood event on 8-9 September 2002. Based on the comprehension of the model, the parameters of different factors in the model are changed to evaluate the effects of these factors on the motorists’ exposure to road submersion in flash floods events. The results of running different simulations for different scenarios show that there is a big variability between each simulation and between each individual exposure and the changes of the parameters in the decision-making model have not really affected the final result. The future work will have to explain the results of the simulations of the model and to investigate further ways to reduce the variability of exposure between different simulations.
Cross-Cultural Comparisons of English Request Speech Acts in Native Speakers of English and Chinese

This paper aims at comparing the uses of the English request speech acts in native speakers of English and Chinese. An oral discourse completion task (ODCT) was used to collect data and the chi-square analysis method was applied to examine the data. From the results, the comparisons of request strategies and internal modifications between Chinese and English native speakers showed no significant differences; both groups frequently used indirect strategies. However, with regard to the use of alerts and external modifications, significant differences were found between these two groups. Further results also indicated the effects of social status and familiarity on both groups. To interlocutor in higher status, both groups showed significantly different usages of internal and external modifications. As to interlocutors in equal status, they performed different request strategies, alerts and external modifications. In addition, significant differences were found in the use of alerts to interlocutors in lower social status. To familiar interlocutors, both groups showed different usages in alerts and external modifications. To unfamiliar interlocutors, significant differences were also found in the use of alerts and external modifications. At last, Chinese native speakers with high and low proficiency levels showed significantly different usages in alerts. Key words : English request speech act; Oral discourse completion task; Chi-square analysis; English native speaker; Chinese native speaker
Advertising Effectiveness by Social Media Influencer Type: The Moderating Role of Consumer Social Comparison Orientation

An influencer is an individual who can impact the potential customers of a brand/product by assisting marketing activities (Brown & Hayes, 2008). As social media provides a network to reach a large population of consumers in a short time, influencer marketing has become prominent (Evans, Phua, Lim, & Jun, 2017). Thus, it is imperative for brand managers to relay their marketing messages to right influencers for their brands/products. This study attempts to understand the effect of social media influencer type on advertising effectiveness. In so doing, this study examines the moderating role of consumer social comparison orientation.
Greenland Ice Sheet solid ice discharge from 1986 through 2017

Abstract. We present a 1986 through 2017 estimate of Greenland Ice Sheet ice discharge. Our data include all discharging ice that flows faster than 100 m yr−1 and are generated through an automatic and adaptable method, as opposed to conventional hand-picked gates. We position gates near the present-year termini and estimate problematic bed topography (ice thickness) values where necessary. In addition to using annual time-varying ice thickness, our time series uses velocity maps that begin with sparse spatial and temporal coverage and end with near-complete spatial coverage and 6 d updates to velocity. The 2010 through 2017 average ice discharge through the flux gates is ∼488±49 Gt yr−1. The 10 % uncertainty stems primarily from uncertain ice bed location (ice thickness). We attribute the ∼50 Gt yr−1 differences among our results and previous studies to our use of updated bed topography from BedMachine v3. Discharge is approximately steady from 1986 to 2000, increases sharply from 2000 to 2005, and then is approximately steady again. However, regional and glacier variability is more pronounced, with recent decreases at most major glaciers and in all but one region offset by increases in the NW (northwestern) region. As part of the journal's living archive option, all input data, code, and results from this study will be updated when new input data are accessible and made freely available at https://doi.org/10.22008/promice/data/ice_discharge.
HeinzelCluster: accelerated reconstruction for FORE and OSEM3D

Using iterative three-dimensional (3D) reconstruction techniques for reconstruction of positron emission tomography (PET) is not feasible on most single-processor machines due to the excessive computing time needed, especially so for the large sinogram sizes of our high-resolution research tomograph (HRRT). In our first approach to speed up reconstruction time we transform the 3D scan into the format of a two-dimensional (2D) scan with sinograms that can be reconstructed independently using Fourier rebinning (FORE) and a fast 2D reconstruction method. On our dedicated reconstruction cluster (seven four-processor systems, Intel PIII@700 MHz, switched fast ethernet and Myrinet, Windows NT Server), we process these 2D sinograms in parallel. We have achieved a speedup >23 using 26 processors and also compared results for different communication methods (RPC, Syngo, Myrinet GM). The other approach is to parallelize OSEM3D (implementation of C Michel), which has produced the best results for HRRT data so far and is more suitable for an adequate treatment of the sinogram gaps that result from the detector geometry of the HRRT. We have implemented two levels of parallelization for our dedicated cluster (a shared memory fine-grain level on each node utilizing all four processors and a coarse-grain level allowing for 15 nodes) reducing the time for one core iteration from over 7 h to about 35 min.
Correlation between single-wire and multi-wire tripping of the flow past a circular cylinder

An experimental study is carried out to explore if the collective influence of multiple tripwires applied spanwise on a circular cylinder can be correlated to the well-known effects of single-wire tripping from previous studies. Constant Temperature Anemometry and Particle Image Velocimetry tests were conducted on single-wire- and two-wire-fitted cylinders in subcritical flow. Noting that a single tripwire can only influence the shedding frequency when it is within a certain range of locations on the cylinder surface, two scenarios for two-wire-fitted cylinders are noteworthy: (1) One of the two wires can fall within this range of locations. This is the case where flow features for the two-wire-fitted cylinder are identical to the single-wire-fitted one. In this category, the Karman vortex shedding loses its coherence and a bistable separation behavior sets in when the influential wire is at the first critical location (+/−θc1) of the single-wire application. (2) Both tripwires can be in the range of locations where the single tripwire application influences the shedding frequency. This is the scenario where flow is controlled by both tripwires. The most dominant influence comes from the tripwire that is closer to the θc location (another critical location identified by previous studies for single-wire applications). Furthermore, in this category, the drastic attenuation of the Karman instability and the onset of the bistable shear-layer separation occur when one of the wires is at a new θc1 location that is about 5°–7° larger than the θc1 reported for single-wire tripping by previous studies. This change in θc1 comes together with a large degree of near-wake contraction to satisfy the simultaneous entrainment demand needed for the early transition of both shear layers in the two-wire-fitted case. A shortage of fluid in satisfying such an increased entrainment demand is speculated to be the cause of the observed shift in θc1.

Suggestions were given according to the results.
Bloch Analysis of Artificial Lines and Surfaces Exhibiting Glide Symmetry

Glide-symmetric structures have recently emerged as a smart choice to design planar lenses and electromagnetic bandgap materials. We discuss here the conditions under which a glide-symmetric structure is equivalent to a nonglide-symmetric structure with a reduced period. To this aim, we propose an analysis method based on network theory to efficiently derive the dispersive behavior of these periodic structures. Both phase and attenuation constants can be determined, with potential applications to both guiding and radiating structures. Retaining higher order modal interactions among cells helps to derive the dispersive behavior of periodic structures more accurately. Furthermore, we take advantage of the higher symmetry of these structures to decrease the computational cost by considering only one half or one-quarter of a unit cell instead of the entire cell. We study one and 2-D glide-symmetric structures and confirm the validity of our analysis with comparisons from commercial software.
Privacy regulation cannot be hardcoded. A critical comment on the ‘privacy by design’ provision in data-protection law

‘Privacy by design’ is an increasingly popular paradigm. It is the principle or concept that privacy should be promoted as a default setting of every new ICT system and should be built into systems from the design stage. The draft General Data Protection Regulation embraces ‘privacy by design’ without detailing how it can or should be applied. This paper discusses what the proposed legal obligation for ‘privacy by design’ implies in practice for online businesses. In particular, does it entail hard-coding privacy requirements in system design? First, the ‘privacy by design’ provision in the proposed Regulation is analysed and interpreted. Next, we discuss an extreme interpretation – embedding data protection requirements in system software – and identify five complicating issues. On the basis of these complications, we conclude that ‘privacy by design’ should not be interpreted as trying to achieve rule compliance by techno-regulation. Instead, fostering the right mindset of those responsible for developing and running data processing systems may prove to be more productive. Therefore, in terms of the regulatory tool-box, privacy by design should be approached less from a ‘code’ perspective, but rather from the perspective of ‘communication’ strategies.
Unexpected Utilizations of Information Technology: off Interaction between Users and EDI

This paper studies the interaction between a specific information system, namely, the Electronic Data Interchange (EDI), and its users. This interaction is addressed by arguing that EDI does not only have expected functions but also unforeseen ones. We assume that activity, e.g., everyday practice, is a relevant level of analysis for the interaction between users and EDI. This paper outlines a model of user-technological artifact interaction by drawing on the activity theory framework. This model, termed instrument-mediated and object-oriented activity, distinguishes the technological artifact from its users’ utilizations. Furthermore, the model focuses on the dialectical relation between users and object-oriented activity, mediated by technology. These developments are illustrated with an empirical study carried out in a multinational enterprise using EDI. The results show different EDI-in-use and point out a double shaping between users and EDI.
Regularized Zero-Variance Control Variates

Zero-variance control variates (ZV-CV) are a post-processing method to reduce the variance of Monte Carlo estimators of expectations using the derivatives of the log target. Once the derivatives are available, the only additional computational effort lies in solving a linear regression problem. Significant variance reductions have been achieved with this method in low dimensional examples, but the number of covariates in the regression rapidly increases with the dimension of the target. In this paper, we present compelling empirical evidence that the use of penalized regression techniques in the selection of high-dimensional control variates provides performance gains over the classical least squares method. Another type of regularization based on using subsets of derivatives, or a priori regularization as we refer to it in this paper, is also proposed to reduce computational and storage requirements. Several examples showing the utility and limitations of regularized ZV-CV for Bayesian inference are given. The methods proposed in this paper are accessible through the R package ZVCV.
A wide input range analog multiplier for neuro-computing

A wide input range 4-quadrant analog multiplier design and its VLSI implementation are presented. The design is based on the squaring law operation of saturated NMOS transistors. The circuit is realized by using 12 NMOS and 2 PMOS transistors. The multiplier accepts two signed inputs in the range of /spl plusmn/4 V. The simulated corner frequency is found to be at 85 MHz. N-well 2 /spl mu/m CMOS double metal process is utilized. It occupies 99/spl times/160 /spl mu/m/sup 2/. Statistical linear regression showed that the multiplier has less than 1% overall error. By extending the input range and minimizing the silicon area, this design has high potential in evolving neuro-computing applications.
Market Symmetry and Its Application to Pattern-Matching-Based Portfolio Selection

Portfolio selection based on pattern matching has shown great potential. The authors show that this approach can be derived from a symmetric market perspective, in which the relationship between market status and optimal portfolio is quantitatively defined in terms of a Pearson correlation. This new perspective motivated a revised pattern-matching algorithm (symmetric CORN-K), which selects the portfolio that simultaneously maximizes the returns of similar periods and minimizes the returns of dissimilar periods. The algorithm was further extended to a general symmetry-based pattern-matching algorithm (functional CORN-K) that uses the symmetry property in a principled way. The authors’ experiments demonstrated that the new algorithms can deliver better returns, larger Sharpe ratios, and lower maximum drawdown, and that the improvements are statistically significant.
Optimising nitrogen fertiliser in high yielding irrigated cotton: A benefit-cost analysis and the feasibility of participation in the ERF

Maximising nutrient use efficiency and minimising emissions of the powerful greenhouse gas nitrous oxide, could enable Australian producers of high yielding irrigated cotton to participate in the Emissions Reduction Fund. This paper reviews nitrogen (N) use in the cotton industry in Australia to date and the challenges of achieving optimal N use in commercial growing practices. The study quantifies both the social and economic parameters in a benefit-cost analysis using two scenarios: an optimal use of N fertiliser and an overuse of N fertiliser in irrigated cotton production. Results of sensitivity analysis for social and economic costs have implications for policy makers focusing on improved N management and an industry supplying an increasingly environmentally aware global market. The study also contains preliminary modelling using industry research of a cotton-N emissions abatement project under the Australian Government’s Emissions Reduction Fund.
Stochastic homogenization of Λ-convex gradient flows

In this paper we present a stochastic homogenization result for a class of Hilbert space evolutionary gradient systems driven by a quadratic dissipation potential and a Λ-convex energy functional featuring random and rapidly oscillating coefficients. Specific examples included in the result are Allen-Cahn type equations and evolutionary equations driven by the p-Laplace operator with p∈(1,∞). The homogenization procedure we apply is based on a stochastic two-scale convergence approach. In particular, we define a stochastic unfolding operator which can be considered as a random counterpart of the well-established notion of periodic unfolding. The stochastic unfolding procedure grants a very convenient method for homogenization problems defined in terms of (Λ-)convex functionals.
