Input allocation in multi-output settings: Nonparametric robust efficiency measurements

Abstract Comparing decision making units to detect their potential efficiency improvement, without relying on parametric unverifiable assumptions about the production process, is the goal of nonparametric efficiency analysis (such as FDH, DEA). While such methods have demonstrated their practical usefulness, practitioners sometimes have doubts about their fairness. In multi-output settings, two main limitations could give credit to their doubts: (1) the production process is modelled as a “black box,” i.e., it is implicitly assumed that all the inputs produce simultaneously all the outputs; (2) only techniques investigating for outliers in all output directions simultaneously exist. In this article, we tackle these two limitations by presenting two new nonparametric robust efficiency measurements for multi-output settings. Our new measurements present several attractive features. First, they increase the realism of the modelling by taking the links between inputs and outputs into account, and thus tackle (1). Second, they provide flexibility in the outlier detection exercise, and thus also tackle (2). Overall, our new measurements better use the data available, and can be seen as natural extensions of well-known nonparametric robust efficiency measurements for multi-output contexts. To demonstrate the usefulness of our method, we propose both a simulation and an empirical application.
Fast Processing Intelligent Wind Farm Controller for Production Maximisation

A practical wind farm controller for production maximisation based on coordinated control is presented. The farm controller emphasises computational efficiency without compromising accuracy. The controller combines particle swarm optimisation (PSO) with a turbulence intensity–based Jensen wake model (TI–JM) for exploiting the benefits of either curtailing upstream turbines using coefficient of power ( C P ) or deflecting wakes by applying yaw-offsets for maximising net farm production. Firstly, TI–JM is evaluated using convention control benchmarking WindPRO and real time SCADA data from three operating wind farms. Then the optimised strategies are evaluated using simulations based on TI–JM and PSO. The innovative control strategies can optimise a medium size wind farm, Lillgrund consisting of 48 wind turbines, requiring less than 50 s for a single simulation, increasing farm efficiency up to a maximum of 6% in full wake conditions.
BREAKING THE σ8−Ωm DEGENERACY USING THE CLUSTERING OF HIGH-z X-RAY ACTIVE GALACTIC NUCLEI

The clustering of X-ray selected active galactic nuclei (AGNs) appears to be a valuable tool for extracting cosmological information. Using the recent high-precision angular clustering results of ∼30,000 XMM-Newton soft (0.5–2 keV) X-ray sources, which have a median redshift of z ∼ 1, and assuming a flat geometry, a constant in comoving coordinates AGN clustering evolution, and the AGN bias evolution model of Basilakos et al., we manage to break the σ8–Ωm degeneracy. The resulting cosmological constraints are Ωm = 0.27+0.03−0.05, w = −0.90+0.10−0.16, and σ8 = 0.74+0.14−0.12, while the dark matter host halo mass, in which the X-ray selected AGNs are presumed to reside, is M = 2.50+0.50−1.50 × 1013 h−1 M☉. For the constant Λ model (w = −1) we find Ωm = 0.24 ± 0.06 and σ8 = 0.83+0.11−0.16, in good agreement with recent studies based on cluster abundances, weak lensing, and the cosmic microwave background, but in disagreement with the recent bulk flow analysis.
Occlusion for 3D Object Manipulation with Hands in Augmented Reality

By dynamically enhancing the reality with a wide range of applications, augmented reality has been drawing growing attention during recent years. Due to the need to interact with virtual objects, hand-object interaction has become a critical element in these applications. By enhancing existing objects with virtual visual appearance, tactile feedback can be provided to the user as well. However, to deal with problems of augmenting real objects with virtual data, a correct visual representation is needed. This becomes even more critical when the interaction between virtual and real objects happens. Incorrect occlusion information can be fatal to an immersive augmented reality experience. In this paper, we propose an innovative approach to handle the occlusion of augmented 3D object manipulation with hands in real-time by exploiting the nature of hand pose combined with tracking-based and model-based methods for estimating occlusion, to achieve a complete augmented reality experience without the necessities of heavy computations, complex manual segmentation processes or wearing special gloves.
Politeness in Intercultural Email Communication: Australian and Korean Perspectives

This paper presents initial results from analysis of data collected on the topic of politeness in intercultural email communication from a large cohort of Australian academic and general staff at an established metropolitan university. We were interested in the language used by these staff members while they conducted their initial email communication with their contacts overseas. The contacts overseas were, for example, fellow professional colleagues, representatives from educational institutions and foreign students. The staff members did not know personally their overseas email partners in the sense that they had not previously met face-to-face. In particular, we were interested in if and how the staff members incorporated politeness indicators in their email language and how they interpreted politeness, or lack thereof, in their incoming emails. The paper also describes and analyses the politeness strategies in intercultural emails used by a smaller cohort of Korean academics at seven universities in Korea. Results show differences in politeness, both in expectations and use, between Australian and Korean academics. Themes and conceptual developments were identified in the primary data-gathering instrument, the questionnaire, using qualitative data analysis. The software package Leximancer was used for text analysis (Smith 2002). The software analysis confirms and strengthens our own qualitative analysis. Results show aspects such as formality in language and use of correct titles are important politeness considerations in intercultural email communication. These politeness considerations however, vary according to culture and results show many discrepancies on these and other aspects between the Australian and Korean data. Figures showing ranked themes display these results visually.
Training and testing in open versus closed kinetic chain

Optimization of different forms of training and testing in sports and therapy has traditionally been debated by various groups. Especially, the use of so-called open and closed kinetic chain exercises has frequently been a focal point. Scientific studies have indicated that no specific form of exercise and/or training has any particular advantage over the other. This applies to both assessment of efficiency, consideration of compression and shear forces, muscular activity and the extent of co-contractions. Unlike the broadly-applied non-specific and uncritical assessment of open and closed kinetic chain exercises, a specific application using the advantages of both procedures must be considered due to clinical, therapeutic and training- physiological aspects. Specificity refers to the training of either an isolated joint-muscle unit (arthron) or a system (group) of joints and muscles. Considering the original definitions and past misinterpretations, it appears logical to emphasize the role of physiological mecha- nisms operating in each form of training and testing. Therefore, the use of the term: single-joint (SJ) or multi-joint (MJ) training, is recommended since this would best reflect the area of application, according to a recent consensus expressed by EISCSA. Consequently, SJ and MJ exercises should be applied both in isolation and in combination as indicated by the principles of specificity. On the other hand, continuous use of the terms open and closed kinetic chain exercises is confusing, erroneous, leads to polarizing discussions and should hence be relegated to the past.

Clinical applications of virtual, non-contrast head images derived from dual-source, dual-energy cerebrovascular computed tomography angiography

The development of computed tomography (CT) has given rise to both multi-slice spiral CT and radiation dose control, aimed at expanding the applications of CT. Furthermore, the temporal resolution of DE-CT angiography (DE-CTA) head scans has been improved to enable the capture of much clearer images. In addition, the single radiation dose required to obtain virtualnon-contrast (VNC) and contrast-enhanced images has been reduced (1-2). Nowadays, VNC is widely applied to multiple organs, included the head (3), but is usually applied to hemorrhages and ischemia. In our study, tumors and calci*ications were also included to *ind the accuracy and consistency of VNC and CNC, which would be of great importance to clinics. ABSTRACT
Feedback-Aided PD-Type Iterative Learning Control

This paper presents a feedback-aided PD-type(FAPD) iterative learning control(ILC) algorithm for linear time-invariant systems. The convergence analysis of the proposed learning algorithm is conducted, and sufficient convergence condition are derived. Furthermore, the initial rectifying strategy is applied to eliminate the effect of fixed initial errors. This result is generalized to higher order systems. It is shown that the system output converges to the desired one in finite time, whatever value the fixed initial shift takes. Numerical simulations are given to demonstrate effectiveness of the proposed learning algorithms.
Localized muscle fatigue during isotonic and nonisotonic isometric efforts

Work-related musculoskeletal disorders (WMSDs) are prevalent in the workplace, and epidemiology studies show that these problems do not tend to diminish. While the use of new and advanced technology has substantially reduced the amount of physical workload, repetitive manual activities are still typically observed in various work settings. Despite their fairly low workload intensity, prolonged repetitive tasks have been associated with the development of musculoskeletal complaints and problems. Research on localized muscle fatigue (LMF) has been viewed as a viable endeavor toward understanding the processes and mechanisms associated with WMSDs. A mounting of evidence on local fatigue during sustained static work has been presented, but much less is known with respect to muscle fatigue during more complex activities. A study was conducted with the primary objectives of determining the repeatability of several commonly used fatigue measures, and to evaluate the presence of long-lasting effects of fatigue from different recovery periods. Based on low-level intermittent arm abductions, findings from this study demonstrated that the use of perceptions of muscular discomfort and muscle strength as fatigue measures was satisfactory. In contrast, electromyography (EMG)-based measures were characterized by a fairly low repeatability. The study also suggested that, whenever practical, two days of recovery should be allotted in studies involving multiple exposures to fatiguing protocols. Long lasting effects of fatigue could be present when shorter amounts of recovery period were assigned. A second study was also carried out to investigate the effects of work parameters (force-level, work-rest ratio, and work cycle) on muscular fatigue during intermittent static efforts. It was suggested that work conditions with muscular contraction level less than 12% MVE was nonfatiguing, irrespective of the values of the work parameters selected. Intermittent work with higher levels of muscle contraction might be acceptable, but it was dependent upon interactions of the other two parameters. The effects of dynamic work conditions on muscle fatigue were investigated in another study. Findings from this third study suggested that muscles responded differently under dynamic conditions and the use of typical EMG measures (dynamic EMG) could be less sensitive. This study further demonstrated that fatigue evaluations during such conditions were difficult, and only a limited number of EMG-based measures could be potentially employed.
Canadian Journal of Counselling and Psychotherapy / Revue canadienne de counseling et de psychothérapie

This article is derived from a study of clients' moment-to-moment experience session. Their recollections of the experience were stimulated through the replay of a tape of the session and the transcribed interviews were analyzed in tenus of the grounded theory form of qualitative analysis. The article focuses on accounts given by some of these clients indicating that they were resistant to their counsellor because they were ambivalent about his or her approach to counselling. The returns from the analysis are discussed in terms of current notions of resistance and of the concept of the working alliance in counselling.
SYMBOL LASER PROJECTION DISPLAY ( LPD ) : A MINIATURE , HIGH RESOLUTION PROJECTION ENGINE

INTRODUCTION In recent years, mobile devices such as PDAs, cell phones and laptops have become smaller and more powerful, while the end user markets for such products have become increasingly ubiquitous. However, the human interface elements (e.g. displays and keypads) are posing limitations on the ability of OEMs to continue to reduce the size of these devices. Symbol's laser projection display (LPD) technology can resolve this issue for the display element by providing a very small, power efficient display engine which produces full color, high quality images.
Effects of Self-Efficacy and Attributions on Teachers ’ Well-Being : A Mediational Analysis

Whereas several studies in the field of achievement motivation have focused on students, there are surprisingly little research on motivation in teachers, which is surprising given high levels of burnout, low job satisfaction, and a high dropout rates among instructors. Prior research suggests that teachers’ self-efficacy plays an important role in predicting job satisfaction (Moe et al., 2010; Caprara, Barbaranelli et al., 2003), quitting intentions, and burnout (Skaalvik & Skaalvik, 2009, 2010) among teachers. Other studies show that although teachers’ stress levels are very high (Borg & Riding, 1991), the way they attribute occupational stress can greatly influence their psychological well-being (e.g., Manassero et al., 2006). Furthermore, Bandura’s (1986, 1994) social cognitive theory proposes that self-efficacy influences the types of causal attributions individuals make for situational events. Therefore, the present study evaluated the effects of both teacher’s self-efficacy and the way they attribute their occupational stress on burnout, job satisfaction, and quitting intentions based on the assumption that teachers’ attributions should mediate the relationship between self-efficacy and adjustment outcomes.
ROLE OF GBV-C AND HUMAN HERPES VIRUS COINFECTIONS IN AIDS DEVELOPMENT IN HIV-1 SEROCONVERTERS

Background: GB virus type C (GBV-C) co-infection prolongs survival among Human Immunodeficiency Virus (HIV) infected individuals. Chronic immune activation is associated with HIV-1 disease progression. Objective: To investigate the effect of GBV-C coinfection and herpes virus reactivation on AIDS development in HIV-1 seroconverters. Methods: A total of 272 men HIV-1 seroconverters were included for the analysis. Cox proportional hazards (PH) regression models were employed to evaluate the effects of GBV-C and herpes viruses (CMV, EBV, HHV6, HHV8) on time from HIV-1 seroconversion to AIDS development. In addition, Gray’s piecewise constant time-varying coefficient (PC-TVC) model that accounts for varying covariate effects over time was employed to estimate the effects for the variables that did not follow PH assumption. Results: In Cox PH model analysis, GBV-C coinfection delayed AIDS development statistically significant in HIV-1 seroconverters. The log10 GBV-C RNA increase was associated with a 15% decrease in AIDS development, while the high HHV8 and CMV reactivation increased AIDS development respectively. The effects of HHV6 and EBV on AIDS development were not statistically significant. Using Gray PC-TVC model, GBV-C coinfection was associated with delaying AIDS development, especially starting from year 3 of HIV-1 infection, then the hazard ratios decreased over time until 10 years, and kept in low level after 10 years of infection. HHV8 reactivation increased the chance of AIDS development, especially after 3 years of HIV-1 infection. The effect of CMV reactivation was constant with a hazard ratio of 1.38. In addition, two variables, age and baseline CD4+ T cell counts, which were not statistically significant in Cox PH regression model analysis, were statistically significant in Gray PC-TVC model. Similar to Cox PH analysis, the effects of HHV6 and EBV were not statistically significant either on AIDS development. Conclusion: GBV-C co-infection delayed HIV-1 disease progression. HHV8 and CMV accelerated AIDS development. The effects of HHV6 and EBV were not statistically significant on AIDS development. Public health importance: This study has important implications for investigating viral coinfections on AIDS development and providing alternative ideas to delay HIV disease progression.
FLOW AND HEAT TRANSFER BEHAVIORS OF WATER-BASED NANOFLUIDS CONFINED IN NANOCHANNEL BY MOLECULAR DYNAMICS SIMULATION

The present work reports a molecular dynamics simulation on the flow and heat transfer behaviors of water-based nanofluids confined in a nanochannel. The Brownian motion of nanoparticles in the base fluid is analyzed. Rotational velocity of nanoparticle is found to be in the range of 1×10 9 ~1×10 10 rad/s. Translational velocity of nanoparticles is calculated by MD simulation to be approximately 10m/s. By means of rotational and translational Peclet number the effect of nanoparticle movements for heat transfer augmentation with nanofluids have been verified. It is also found that the local velocity and temperature of nanofluids near the fixed wall is evidently higher than that of base fluid, which indicates the velocity gradient and temperature gradient of nanofluids near the fixed wall is greater than those of single-phase base fluid. The change of nanofluid velocity and temperature profiles is attributed to the high-speed micro-motions of nanoparticles.
Non-Coherent Massive SIMO System Based on M-DPSK for Rician Channels

In this paper, we propose a new constellation design for a non-coherent massive single input multiple output (m-SIMO) uplink system based on M-DPSK suitable for Rician channels. Under Rician propagation, the non-coherent systems proposed until now cannot completely remove the interference. This new design takes into account the inter user and inter symbol interferences in order to convert them into useful terms that help us in the non-coherent detection. We propose an algorithm to non coherently detect the joint symbol with the information from all users leveraging the characteristics of the new constellation. In addition, the signal-to-interference-plus-noise ratio is derived and is used to present analytical bounds for the symbol error rate. It is shown that the analytical results tightly match the numerical simulation. We show that with the proposed constellation and detection algorithm we are able to leverage the line-of-sight component of the Rician propagation, obtaining a better performance than with Rayleigh channels.

Foreign Media Framing of Boko Haram Insurgency : A Critical Analysis of BBC and Aljazeera Online Coverage

The 2015 Global Terrorism Index (GTI) indicates that Boko Haram, which majorly operates in Nigeria, has overtaken ISIL and has become the most dreadful terrorist group in the world, a figure that has placed Nigeria on the world map as the most terrorised country. This study is a critical evaluation of foreign media coverage of Boko Haram insurgency, using media framing as a theoretical framework. A qualitative content analysis was conducted on stories about Boko Haram that appear on the websites of two leading international broadcast media organisations – BBC and Aljazeera. In this study, twelve stories each were sampled from the BBC and Al-Jazeera websites using purposeful random sampling. The study found that BBC framing of Boko Haram insurgency took stereotypic dimension of age-long and deep-rooted narratives of western media that associate Islam with barbarism, killing, suicide-bombing, fanaticism, extremism, and terrorism. Al-Jazeera posture on Boko Haram coverage on the other hand, tends to counter the stereotypic disposition and dominant narratives of western media by establishing the fact that there are “good” Muslims who are committed to propagating peace in the multi-religious society. The findings further expose how western media capitalise on the socio-economic and political failures of African countries to influence the political and economic bearings of these nations. Unlike Al-Jazeera that appeared fair to both the ruling and the opposition parties, the BBC tend to confer the status of competence on the opposition party by continuously portraying the ruling party as grossly incompetent in tackling the menace of Boko Haram. The study recommends that BBC and other foreign media should be more balanced in its reportage of terrorism in foreign countries by downplaying on the religious status of perpetrators. This is because, when all Muslims are labelled as terrorists, the sympathy the world deserves from “good” Muslims when tackling terrorism would diminish, naturally.
