Design and analysis of dual pressure probes for predicting turbulence-induced vibration in low velocity flow

Measuring highly turbulent fluid flow is challenging, especially in cases where the turbulence intensity exceeds acceptable limits for hotwire anemometry techniques. Using fast response pressure probes is an effective and well documented turbulence measurement method; however, there is little literature about pressure probes capable of measuring turbulence in low mean velocity air flows (0-12 m/s). Also lacking in the literature is a complete method of using pressure probe measurements to predict turbulence-induced vibration. In this paper the design and analysis of two highsensitivity pressure probes is discussed. It will be shown how measurements with these probes are used to develop a statistically derived turbulent fluid forcing function. This function will then be combined with an analytical structural dynamics model such that not only the modal RMS displacements, but also the modal displacement power spectral density plots can be predicted for a given structure. The pressure probe design, turbulence measurement techniques, and both the statistical and analytical models will be validated with experimental results. The results shown in this paper are for a case study performed with a single cantilever exposed to turbulent cross-flow.
A classification of user experience frameworks for movement-based interaction design

Abstract Recent technological developments have made it possible for digital technology to offer interaction modes that can engage the whole body. These systems can track the users’ movements to support rehabilitation, to play games or to create music, among other activities. One important implication of interacting with the whole body is the increased relevance of the user’s experience. A number of approaches and frameworks have been proposed to design these movement-based systems and some of them pay special attention to the user’s experience. This paper maps the space of design frameworks for movement-based interaction that focus on user experience. It classifies existing frameworks by their type and by characteristics that could help practitioners intending to design applications of that sort to make informed decisions about what framework to employ. Additionally, and to illustrate the use of the classification, we include a case study related with selecting and deploying some of these frameworks for a design exercise.
Societies in transition: are they more sexist? A comparison between Polish, South African and British samples

This study investigates ambivalent sexism to women in student samples from two under-researched transitional countries, Poland (PL) and South Africa (SA), in comparison with the United Kingdom. Based on ambivalent sexism theory (AST), and in light of socio-economic context, it was hypothesised that: (1) the sample in PL and SA would be more hostile- and benevolent-sexist than the sample from the UK, (2) males would exhibit more hostile attitudes than females irrespective of country and (3) males would outscore females on benevolent attitudes in the relatively liberal UK but underscore them in relatively conservative SA. The Ambivalent Sexism Inventory was used to measure benevolent and hostile sexism. The findings largely supported the hypotheses. The participants in SA and PL were more sexist than in the UK and men were more hostile-sexist than women in all three countries. However, males outscored females on benevolent sexism not only in the UK but also in SA and PL. Moreover, the sample from PL was observed to be more sexist than the sample from SA. The findings are discussed in light of AST and the countries' transitional context.
Tax Law Asymmetries and Income Shifting: Evidence from Japanese Capital Keiretsu

Abstract While the asymmetric treatment of positive and negative income creates clear tax incentives to shift income among a group of closely related corporations, attempts to document the impact of such behavior on economic outcomes are relatively sparse. We aim to provide evidence on tax-motivated transfers from a large dataset of Japanese corporate groups. Using company level data on 33,340 subsidiary time pairs from 1988, 1990, and 1992, we consider testable implications of income shifting in a theoretical model tailored to the Japanese institution of the early 1990s and empirically examine the spread of the profitability distribution, the attrition rate of loss-making subsidiaries, and the propensity to report zero profit. The findings suggest that income shifting was pervasive when Japan had not adopted a formal allowance for group-level tax. The result underscores the importance of accounting for the inter-relatedness of companies, in designing a corporate income tax.
BROADBAND CPW-FED ANTENNA WITH BAND- REJECTED CHARACTERISTIC FOR WLAN/WIMAX OPERATION

A novel single-layer broadband coplanar waveguide- fed antenna with band-rejected characteristic is proposed for WLAN/WiMAX operation. First, the broadband characteristic (2.43{ 5.97GHz) is achieved by a CPW-fed patch antenna with a dual-Y slot. Then, a single slit is inserted on the radiating patch or ground plane to introduce a notched band. The proposed antenna has a compact size of 40 £ 25mm 2 . The broadband characteristic and band-rejected functions of the proposed antennas are implemented and measured. Two types of antennas were studied. Measured notched- band impedance bandwidths (return loss < 10dB) are 370MHz and 1050MHz, respectively, which satisfles the requirements for WLAN and WiMAX applications. Detailed design steps and experimental results for the designs are studied and investigated in this paper.
Determinants of the Adaption of Organic Agriculture in Egypt Using a Duration Analysis Technique

A very important pillar of the modernization of the Egyptian agriculture depends upon the exportation of the high value added products such as organic products. In spite of the importance of the organic agriculture within the Egyptian agriculture sector and up to our knowledge, it does not exist in Egypt until now any study that try to determine and analyze the determinant factors of the adaption of the organic agriculture within the Egyptian farms. In this study, we focus on this issue. A survey with a representative sample of organic and non-organic farms in Upper Egypt area was carried out. Using obtained data set we apply duration analysis techniques to assess the effect of different explanatory variables on both the adoption of organic agriculture farming and the timing of this adoption. Our results suggest that the maximum hazard of adopting organic agriculture takes place during the first few years after the construction of the farm and Manager characteristics such as his education level and Risk behaviour together with the farm size seem to be the most significant factors affecting the likelihood of organic agriculture adoption in Egypt. These results could be helpful in designing the suitable policies and strategies to support the extension of organic agriculture within Egypt.
F 2 C Routing in Vehicular Delay Tolerant Network

There is a lot of ongoing work in the area of DTN research. Because these systems often comprise several tens, hundreds or even thousands of nodes, a real-world test is a very costly and time consuming operation. Most research is carried out using simulators, because it allows for fast and cheap evaluation of protocols and applications in a controllable and reproducible manner. A simulation study uses abstractions (i.e. models) in order to make a judgment on real-world feasibility. This paper proposes controlled flooding based routing algorithms for a VDTN. It is shown that FirstTwoContact and FirstTwoMobileContact routing algorithms improve significantly the delivery probability compared to traditional single copy approach. This paper proposes and simulates the new protocol to maximize delivery ratio.
Towards a Constraints Approach to Generating Personalised Horror Film Variants

In this work we explore the use of a Constraint Programming (CP) model for the selection of suitable ﬁlmic content to use to output a horror narrative in a way that is personalised to a particular viewer type. We adopt a bipartite representation of narrative where planning is used to generate an outline narrative and then CP is used to build the discourse presentation: the ﬁlmic variant that is presented to the viewer. In the paper we overview our model and illustrate it with example horror variants generated by our prototype system. We also present an analysis of sample ﬁlmic sequences output by the system along with the results of a small user evaluation which demonstrate the potential of the approach.
A Nonsingular Terminal Sliding Mode Approach Using Adaptive Disturbance Observer for Finite-Time Trajectory Tracking of MEMS Triaxial Vibratory Gyroscope

This paper develops a nonsingular terminal sliding mode controller (NTSMC) with adaptive disturbance observer (ADOB) for finite-time trajectory tracking of a MEMS triaxial vibratory gyroscope, which has parameter variations and external high-amplitude disturbance. A novel sliding mode controller with adaptive disturbance observer is designed to reconfigure the parameter variations and external high-amplitude disturbance and reduce the chattering phenomenon on the sliding surface greatly through setting the switching gain in control signal as a smaller value. The disturbance adaptive law is derived to guarantee the stability of the closed-loop adaptive control system via the Lyapunov criterion. The simulation results are performed to verify the effectiveness of the presented schemes.
APPLYING THE CULTURAL ACCOMMODATION MODEL TO DIVERSITY CONSULTING IN ORGANIZATIONS

In response to the increasing need for more consultation models that take into account culture, this article proposes an integration of Schein’s (1999) Process Consultation Model with Leong’s Cultural Accommodation Model (Leong & Lee, 2006) to address multicultural issues in consultation. Beginning with a review of each of these 2 models, the manuscript moves on to present the integrated CAM–PC Model. This is followed by an illustration of practical application of the CAM in a consultation case.

Performer vs. observer: whose comfort level should we consider when examining the social acceptability of input modalities for head-worn display?

The popularity of head-worn displays (HWD) technologies such as Virtual Reality (VR) and Augmented Reality (AR) headsets is growing rapidly. To predict their commercial success, it is essential to understand the acceptability of these new technologies, along with new methods to interact with them. In this vein, the evaluation of social acceptability of interactions with these technologies has received significant attention, particularly from the performer's (i.e., user's) viewpoint. However, little work has considered social acceptability concerns from observers' (i.e., spectators') perspective. Although HWDs are designed to be personal devices, interacting with their interfaces are often quite noticeable, making them an ideal platform to contrast performer and observer perspectives on social acceptability. Through two studies, this paper contrasts performers' and observers' perspectives of social acceptability interactions with HWDs under different social contexts. Results indicate similarities as well as differences, in acceptability, and advocate for the importance of including both perspectives when exploring social acceptability of emerging technologies. We provide guidelines for understanding social acceptability specifically from the observers' perspective, thus complementing our current practices used for understanding the acceptability of interacting with these devices.
Data report: microbial abundance in subseafloor sediments of the equatorial Pacific Ocean, Expedition 320/321 1

Microbial cell abundances in sediment cores from Integrated Ocean Drilling Program Expedition 320/321 were quantified. Cell abundances varied between sites and with depth between >10 6 cells/cm 3 and <10 3 cells/cm 3 . Even when using cell separation to increase sensitivity, cell abundances fall below the minimum detection limit in the deeper parts of several sites. At many of the sites, cell distribution does not follow the generally observed trend of a continuous decline with depth. Only some of these deviations appear to be correlated with lithologic changes.
Phylogeography of Neptune whelk (Neptunea arthritica) suggests sex-biased impact of tributyltin pollution and overfishing around northern Japan

The Neptune whelk, Neptunea arthritica, is a sublittoral snail from Pacific waters that is a food resource and supports a commercially important fishery in northern Japan. This species showed a severe decline during the 1970s and 1980s, possibly because of overfishing, imposex caused by tributyltin (TBT) pollution and parasite infection. In the present study, we investigated genetic variation among the populations of N. arthritica from eight localities in northern Japan, including Hokkaido and Aomori, using a mitochondrial DNA (mtDNA) marker, a partial sequence of the cytochrome c oxidase subunit I (COI) gene. We also addressed the evolutionary history of N. arthritica and human impact on the population genetic profiles of this species. The parsimony network showed 14 COI haplotypes separated into two groups (Groups A and B), with an intermediate haplotype connecting both groups. Among eight populations, six were fixed for only one or two haplotypes, and no geographic-genetic correlation was found; they were probably affected by random drift. These results contrasted with those from previous microsatellite analysis, which indicated that geographic structure was the result of restricted gene flow between populations. Our results suggested that N. arthritica diverged into Groups A and B during the Pliocene; however, recent TBT pollution and size-selective fishing pressure have reduced genetic diversity and concealed the natural population structure. The present study also suggested that human impact may cause longstanding and possibly irreversible modification of ecosystems, particularly for species forming discrete and relatively small local populations, such as N. arthritica. Thus, the combined use of mtDNA and microsatellite genetic data provides a powerful tool to investigate the health of biodiversity in molluscs.
THE EFFECTS OF ACCRETION FLOW DYNAMICS ON THE BLACK HOLE SHADOW OF SAGITTARIUS A*

A radiatively inefficient accretion flow (RIAF), which is commonly characterized by its sub-Keplerian nature, is a favored accretion model for the supermassive black hole at the Galactic center, Sagittarius A*. To investigate the observable features of an RIAF, we compare the modeled shadow images, visibilities, and spectra of three flow models with dynamics characterized by (i) a Keplerian shell that is rigidly rotating outside the innermost stable circular orbit (ISCO) and infalling with a constant angular momentum inside ISCO, (ii) a sub-Keplerian motion, and (iii) a free-falling motion with zero angular momentum at infinity. At near-millimeter wavelengths, the emission is dominated by the flow within several Schwarzschild radii. The energy shift due to these flow dynamics becomes important and distinguishable, suggesting that the flow dynamics are an important model parameter for interpreting the millimeter/sub-millimeter very long baseline interferometric observations with the forthcoming, fully assembled Event Horizon Telescope (EHT). As an example, we demonstrate that structural variations of Sagittarius A* on event horizon-scales detected in previous EHT observations can be explained by the non-stationary dynamics of an RIAF.
Traffic-driven optimalization of resilient QoS-aware Metro-Ethernet networks

The steadily increasing Internet access speeds have made it possible even for home users to reach and use previously unavailable bandwidth consuming services like, VoIP and Video on Demand. The rapid spread of these applications emerges the demand for QoS aware and reliable architectures in Metro Area Networks. At the same time, the low cost and the high speed links make the Ethernet the most cost efficient technology for building Metro Networks. Standardization further extends the capabilities of Ethernet making the Ethernet “Carrier Grade”. Assuming an Ethernet based QoS architecture with resilience capability, this thesis proposes an optimization framework and novel algorithms that support optimal off-line configuration of trees and optimal VLAN assignment to these trees. The optimized configuration considers Quality of Service (QoS), Traffic Engineering (TE) and reliability objectives and can be performed via centralized management plane. The optimization task is formulated as an Integer Linear Program (ILP) and compared to the traffic driven configuration method that use a standard based port cost set. The simulations show that high throughput gain (50–200%) can be realized over the typical metro network topologies. Since the ILP is rather unscalable, the decomposition of the problem is presented and based on it, novel heuristic algorithms are proposed. These algorithms provide near optimal solutions and they are proven to be scalable. Last, but not least, the assumed model and the proposed algorithms are further improved to deal with the requirements of Triple-Play: multicast and statistical multiplexing capabilities. Another direction is to extend the protection capabilities over Optical Ethernet, where Coarse Wavelength Division Multiplexing (CWDM) is applied to serve the huge bandwidths.
Social Policies in Solomon Islands and Vanuatu

SOCIAL POLICIES IN SMALL STATES SERIES The country case studies and thematic papers in this series examine social policy issues facing small states and the implications for economic development. They show how, despite their inherent vulnerability, some small states have been successful in improving their social indicators because of the complementary social and economic policies they have implemented. CASE STUDY – SOLOMON ISLANDS AND VANUATU Solomon Islands and Vanuatu are two small states that have struggled to develop successful social policies since gaining independence. This final study in the series traces the history of social development in both countries, examining closely the factors that have hindered progress: the colonial legacy, poor economic development, high population growth, political instability, the lack of social cohesion, mismanagement of resources and natural disasters. The authors argue that for progress to continue both countries need to move away from a reliance on their traditional social structures and focus on political stability and economic growth.
Traditional Islamic Education in Morocco: Sociohistorical and Psychological Perspectives

As in many parts of the Muslim world, traditional Islamic schooling1 in Morocco predates modern formal schooling by almost a millennium. It has played a crucial historical role in the training of the nation's youth and continues to reach a higher percentage of school-age children than has the modern school system. Although such traditional Quranic schooling may have touched the lives of most Moroccans, its impact--relative to the modern school system--is not yet fully understood. Probably the most difficult aspect of analyzing the impact of traditional Quranic education is that there are several "types" of Quranic schools, and there are a number of levels of analysis upon which such education may be observed and discussed. Any discussion of the consequences of traditional Quranic schooling will, therefore, depend on an adequate understanding of the varieties of this type of traditional education. This paper will discuss present forms of traditional Quranic education in Morocco in the light of modernization. More specifically, discussion will center on the potential impact of such traditional pedagogy on various cognitive abilities, whose growth is sometimes said to have been stunted by such experiences. Quranic schooling, as used in this paper, refers specifically to the elementary and intermediate levels of traditional Quranic education, which provide the learner with the basic skills of reading, writing, elementary notions of grammar, and knowledge of Islamic law. Also, Quranic schooling requires the student to memorize part or all of the Quran itself. In this paper we will not, therefore, focus attention on advanced training in both religious and secular sciences (which were often taught only at the more prestigious mosque-universities), but will instead concentrate on schooling for younger children and adolescents.
Comparison of lignocellulose biodegradation in solid state fermentation of sugarcane bagasse and rice straw by Aspergillus tamarii

The present study examines the lignocellulose degradation in solid state fermentation in sugarcane bagasse and rice straw by Aspergillus tamarii over a period of 21 days. Lignocellulose degradation in sugarcane bagasse and rice straw, fortified with glucose was studied with and without ammonium sulphate. In bagasse fermentation, when the substrate initially containing 17.4% lignin was fortified with 5% glucose in the absence of ammonium sulphate, a maximum lignin loss of 24.7, was recorded. This maximum lignin loss was accompanied by a minimum cellulose loss of 3. In rice straw, fermentation under the same conditions resulted in a maximum lignin loss of 45.5% and 2.8% loss of cellulose. Efficiency of solid state fermentation using the two different substrates indicates that lignin loss is high in comparison to cellulose loss. Key words: lignin, cellulose, fortification, white rot fungi DOI: http://dx.doi. org/10.4038/cjsbs.v40i1. 3408 CJSBS 2011; 40(1): 65-68
Lumpy Investments, Factor Adjustments and Productivity

This paper describes firms' output and factor demand before, during and after episodes of lumpy investments using a rich employer-employee panel data set for two manufacturing industries and one service industry. We focus on the simultaneous adjustment of capital, materials, man-hours, as well as the skill composition and hourly cost of labour. The investment spikes lead to roughly proportional changes in sales, labour and materials, while capital intensity increases significantly. Capital adjustments are found to be smoother in the service industry than in the two manufacturing industries, a difference that may be related to the labour intensity in the service industry. Finally, the changes in productivity associated with episodes of investment spikes are small, indicating that productivity improvements are related to learning-by-doing rather than instantaneous technological changes through investment spikes.
