Identifying the Variables Contributing to At Risk Performance: Initial Evaluation of the Performance Diagnostic Checklist Safety (PDC Safety)

We adapted the Performance Diagnostic Checklist to analyze the environmental events contributing to safe and at risk behaviors by employees in organizations. We then used the resulting tool, the Performance Diagnostic Checklist Safety (PDC Safety) to identify variables contributing to unsafe equipment usage by 3 members of a landscaping crew at a private university. Based on PDC Safety results, an intervention consisting of graphic feedback was implemented. The intervention increased safe performance for all participants.
The Performance Diagnostic Checklist Human Services: a Correction
Venue: Behavior analysis in practice

The Performance Diagnostic Checklist (PDC) has been used in a number of investigations to assess the environmental determinants of substandard employee performance. Carr et al. (2013) revised the PDC to explicitly assess the performance of employees in human service settings who are responsible for providing care to others: the Performance Diagnostic Checklist Human Services (PDC HS) The originally published PDC HS contained three minor scoring errors, which have been corrected in the present version.
Does learning ability differ with personality in dogs

Advances in understanding dog personality and learning ability can help match dogs to an owner or handler, providing a suitable and perfectly matched owner and dog (Coppinger et al, 2004) First, animal cognition is a developing area to measure an individual's welfare. Second, further research into dog personality and learning ability can improve our understanding of factors that affect cognitive performance which is much more complicated than simply intelligence. Third, new found knowledge on personality and learning ability can be used to assess dogs, especially puppies, for suitability for certain tasks. Overall, improved knowledge about a dog's individual personality can help promote better training and welfare (Svartberg, 2002)
Letter to the Editor "On the Feasibility of Noncontact ECG Measurements"
Venue: IEEE Transactions on Instrumentation and Measurement

The article by Kranjec <italic>et al./italic> <xref ref type="bibr" rid="ref1"[1]/xref> "Novel methods of noncontact heart rate measurement: A feasibility study" is interesting and informative as it compares different contactless methods for heart rate detection. Nevertheless, the use of the term "capacitively coupled ECG" (CCECG) in the article is confusing and may mislead readers.
Exchange rate policy and falling crude oil prices: Effect on the Nigerian stock market

This paper examines the effect of crude oil price movement on the Nigerian stock market and the role of exchange rate as a plausible countercyclical policy tool. Daily data on All Share Index of the Nigerian stock market, crude oil prices and exchange rate, were collected for two periods: 2008 2009 and 2012 2015.  model show that oil prices are positively related with the performance of the Nigerian stock market thus would drag the market down in times of turmoil. Howbeit, devaluation of the naira is found to be effective in cushioning the effect of crude oil price decline on the stock market. Results from the granger causality test, however, suggest that this policy measure may not be potent as expected.
Pedestrain detection from motion
Venue: 2016 23rd International Conference on Pattern Recognition (ICPR)

Pedestrian detection is a challenging problem studied over decades. Most algorithms are based on human appearance. Only few works consider motion as a feature component. In this paper, however, we tackle this problem only considering short periods of pedestrian walking. This motion does not depend on the variations of pedestrian pose, body shape, illumination, and background. We model pedestrian motion that has unique properties compare to background and rigid objects motion in spatial temporal motion profiles. This observation helps us to identify pedestrian leg motion along with body motion over a short time period. Our method also works for a vehicle borne camera where background also moves. We achieved more robust results by dealing with crowds, and other degenerating cases of human motion against background and dynamic scenes. The method has a low computational cost on a motion profile and it can be combined with a shape based method as pre screening for reducing the false positives. It also provides a feasible way to find human behaviors.
Starfish (Asteroidea, Echinodermata) from the Faroe Islands: spatial distribution and abundance

Marine benthic fauna of the Faroe Islands" (BIOFAR) is a large programme with a focus on collecting invertebrate fauna from the Faroes (62degN and 7degW) Cruises were undertaken from 1987 to 1990, and starfish (Asteroidea, Echinodermata) collected during this time were analysed. Asteroidea were sampled at ~50% of all BIOFAR stations. A Detritus sledge and a Triangular dredge proved to be the most efficient equipment, collecting over 60% of the specimens. In total 2473 specimens were collected from 20 to 1500 m depth, including 41 species from 17 families and 31 genera. Henricia pertusa (O. F. Muller, 1776) group, Pontaster tenuispinus (Duben Koren, 1846) and Leptychaster arcticus (M. Sars, 1851) showed highest relative abundance. Maximum species diversity was found at 500 700 m depth, which coincides with the transition zone of water masses (North Icelandic Winter Water and Arctic Intermediate Water (NI/AI) at approximately 400 600 m depth. 63% of the species were recorded at an average weighted depth above 600 m. Two different ordination methods (detrended correspondence analysis (DCA) and nonmetric multidimensional scaling (NMDS) gave highly consistent representations of the community structure gradients. The first ordination axis scores did not show significant relationships with any environmental variable. Biological covariates like the presence of Lophelia corals were not significantly related to ordination scores on any axis. The second ordination axis scores were significantly correlated with depth. Temperature and salinity were highly correlated r =0.90) and both negatively correlated with depth r 0.69 and r 0.57, respectively)

Pilot Tone Reference Less Phase Conjugator for Phase Modulated Retrodirective Antenna Applications
Venue: IEEE Antennas and Wireless Propagation Letters

This letter presents a simple tracking phased locked loop (PLL) that can be used to track phase modulated signals and provide a phase conjugated signal for retrodirective retransmission. The configuration allows the retrodirective antenna to directly track phase modulated signals with no requirement for a separate continuous wave (CW) pilot tone. The ability to directly track phase modulated signals is carried out using a 4x multiplier on the tracking PLL reference signal. Practical phase conjugation results are presented for a five element retrodirective array simultaneously sending and receiving phase modulated (QPSK) signals. Signals with levels as low as 122 dBm can be phase conjugated and retransmitted with 30 dBm EIRP.
A Novel Processing Approach for Additive Manufacturing of Commercial Aluminum Alloys

Aluminum 6061 is of great commercial interest due to its ubiquitous use in manufacturing, advantageous mechanical properties, and its successful certification in aerospace applications. However, as an off eutectic with accompanying large freezing range, attempts to process the material by additive manufacturing have resulted in part cracking and diminished mechanical properties. A unique approach using mixed powders is presented to process this historically difficult to process material. Expansion of this combined powder approach to other materials systems not typically compatible with additive manufacturing is possible. Dense parts without solidification cracking have been produced by the SLM process, as verified using SEM and EDS. An overview of this approach is presented along with test results using an Al Si mixture.
Preliminary Investigation into the Suitability of 2xxx Alloys for Wire Arc Additive Manufacturing

An investigation has been performed into the compatibility of aluminum alloys used in the aerospace industry with Wire Arc Additive Manufacturing. Modelling and preliminary experimental trials have been performed to show that it is viable to use Al Cu Mg alloys, like 2024, without solidification cracking. A relatively fine and texture free grain structure was obtained in the as deposited WAAM material and the addition of inter pass deformation, by rolling each added layer, led to further grain size refinement. With adequate control of porosity and subsequent heat treatment, the WAAM material was found to have tensile properties comparable to that of standard wrought products.
Generation of Spatial Temporal Panoramas with a Single Moving Camera
Venue: 2016 13th Conference on Computer and Robot Vision (CRV)

Development of image stitching techniques, whichtake multiple images and stitch them together to make naturallooking panoramas, is an integral part of the new wave invisual media the 360 surround displays, such as the OculusRift. However, as compared to static image stitching, there hasbeen little research conducted on video stitching, especiallymethods of generating panoramic video content from a singlemoving video camera. In this paper we present an effectivemeans of creating video panorama from a single camera. Ourvideo stitching method allows for widening the field of view ofa video while maintaining spatial temporal consistency. In thisapproach, a single image warping transformation, orhomography, is obtained by averaging several rotationmatrices from several frames. The application of the samehomography to every frame, with fixed camera intrinsicparameters, provides enhanced stability of the resultingpanoramic video. This novel stitching method can be used for avariety of applications, such as allowing the creation ofpanoramic video with smartphones and enabling gaming andmovie companies to make panoramic video content in a flexibleand inexpensive manner.
Fast valve power loss evaluation method for modular multi level converter operating at high frequency

There is no common accepted way for calculating the valve power loss of modular multilevel converter (MMC) Valve power loss estimation based on analytical calculation is inaccurate to address the switching power loss and valve power loss estimation based on detailed electro magnetic simulation is of low speed. To solve this problem, a method of valve power loss estimation based on the detailed equivalent simulation model of MMC is proposed. Results of valve power loss analysis of 201 level 500MW MMC operating at 50Hz~1000Hz are presented. It is seen that the valve power loss of a MMC increased by 12, 40 and 93 under 200Hz, 500Hz and 1000Hz operating frequency. The article concludes that in a device with isolated inner AC system, MMC operating at higher frequency will be more competitive than typical 50Hz/60Hz MMC with moderate increase of operating power loss and significant reduction of the size of the AC components.
Some Choreographic Notes on the Dance of Theory with Data: A Response to Roland Boer, The Sacred Economy of Ancient Israel (Louisville: Westminster John Knox Press, 2015)

This volume is a tour de force that exceeds any predecessor in its theoretical scope. Even more important than its intriguing syntheses are its probing questions, its analytical categories and tools, and its challenges to easy assumptions. Boer's pursuit of theoretical integration, however, sometimes leads him to overgeneralize. He staunchly maintains, for example, that arable land was plentiful in all times and places in ancient Southwest Asia. Comprehensive archaeological surveys of the southern Levant tell a different story. The Iron II population was more than double that of the Bronze Age or of Iron I. The highlands particularly witnessed the occupation of marginal niches. Population pressure on arable land was a reality in Iron II Palestine. Similarly, the many standardized wine amphorae recovered from two eighth century BCE. Phoenician ships sunk off the Philistine coast contradict Boer's repeated insistence that there is no evidence for long distance trade in bulk goods.

Sand Production Management the Critical Challenge in Zawtika Gas Production

Sand production continues to be a major challenge in many producing oil and gas assets worldwide. It can choke off production, reduce hydrocarbon recovery, eliminate the integrity of production facilities, and possibly cause disastrous facility failures and harm to personnel and the environment. As such, sand management becomes a priority when selecting appropriate sand control methods and equipment, and mitigation plans need to be addressed to reduce risks and harm resulting from sand production. Undertaken by PTTEPI, the Zawtika gas development project, located offshore Myanmar in the Moattama Basin, covering Block M 9 and a portion of Block M 11, lies within the Zawtika Development Production Area. The area is situated approximately 300 km south of Yangon and 290 km west of Tavoy off the Myanmar coast. Nine structures of discovered gas resource volumes have been dedicated to the Zawtika gas development project. They will be developed over 3 phases, i.e. 1A, 1B and 1C, at a Daily Contract Quantity of 300 MMscfd sales gas. The GSA was concluded and signed between all parties on July 30, 2010. Gas production from Phase 1A development, comprising the first three 3 structures, has been being delivered to buyers since March 10, 2014.
Mixed Metaphors in Muranow: Holocaust Memory and Architectural Meaning at the POLIN Museum of the History of Polish Jews

Since it opened in 2013, the POLIN Museum of the History of Polish Jews in Warsaw has been widely praised by journalists and scholars for its permanent exhibition and striking architecture. Built on the site of the former Warsaw ghetto established by the Nazis in World War II, the museum has been identified as a symbol of improved Polish Jewish relations in the wake of the Holocaust. Few commentators, however, have delved deeply into the complexities of the museum's architectural relationship to the Holocaust. This essay traces the long discussion surrounding the architectural symbolism of the museum from its inception up to its recent completion in order to illustrate how the Holocaust continues to pose major challenges to architects as they wrestle with the task of building after Auschwitz.

Numerical simulation of a direct current glow discharge in atmospheric pressure helium

Characteristics of a direct current (DC) discharge in atmospheric pressure helium are numerically investigated based on a one dimensional fluid model. The results indicate that the discharge does not reach its steady state till it takes a period of time. Moreover, the required time increases and the current density of the steady state decreases with increasing the gap width. Through analyzing the spatial distributions of the electron density, the ion density and the electric field at different discharge moments, it is found that the DC discharge starts with a Townsend regime, then transits to a glow regime. In addition, the discharge operates in a normal glow mode or an abnormal glow one under different parameters, such as the gap width, the ballast resistors, and the secondary electron emission coefficients, judged by its voltage current characteristics.
NUMERICAL SIMULATION OF INTERACTION PROCESS BETWEEN DIELECTRIC BARRIER DISCHARGE AND DUCT FLOW

Numerical procedure of DBD modeling based on RANS equations has been developed and tested in present study both for the standard DBD and DBD working in constricted mode. Qualitative and approximate quantitative correspondence between known experimental data and numerical results has been achieved. Typical volume force and heat magnitudes has been evaluated, these values could be used as estimation in steady approximation calculations. Both DBD actuators models has shown up that required volume force magnitude has to be increased by 2 3 orders influence on flow separation in S type engine ducts at relatively high inlet velocity Different method of volume force calculation using actuator electrical parameters (DPM) has been carried out. Continuous volume force components fields have been calculated as a function of DBD actuator potential difference and charge density amplitude.
Numerical Simulation of Stall Flow Control Using a DBD Plasma Actuator in Pulse Mode

A numerical simulation method is employed to investigate the effects of the unsteady plasma body force over the stalled NACA 0015 airfoil at low Reynolds number flow conditions. The plasma body force created by a dielectric barrier discharge actuator is modeled with a phenomenological method for plasma simulation coupled with the compressible Navier Stokes equations. The governing equations are solved using an efficient implicit finitevolume method. The responses of the separated flow field to the effects of an unsteady body force in various inter pulses and duty cycles as well as different locations and magnitudes are studied. It is shown that the duty cycle and inter pulse are key parameters for flow separation control. Additionally, it is concluded that the body force is able to attach the flow and can affect boundary layer grow that Mach number 0.1 and Reynolds number of 45000.
CFD Based Analysis and Parametric Study of a Novel Wind Turbine Design: the Dual Vertical Axis Wind Turbine

Small Vertical Axis Wind Turbines (VAWTs) are good candidates to extract energy from wind in urban areas because they are easy to install, service and do not generate much noise; however, the aerodynamic efficiency of small turbines is low. Here in a new turbine, with high aerodynamic efficiency, is proposed. The novel design is based on the classical H Darrieus VAWT. VAWTs produce the highest power when the blade chord is perpendicular to the incoming wind direction. The basic idea behind the proposed turbine is to extend that said region of maximum power by having the blades continue straight instead of following a circular path. This motion can be performed if the blades turn along two axes; hence it was named Dual Vertical Axis Wind Turbine (D VAWT) The analysis of this new turbine is done through the use of Computational Fluid Dynamics (CFD) with 2D and 3D simulations. While 2D is used to validate the methodology, 3D is used to get an accurate estimate of the turbine performance. The analysis of a single blade is performed and the turbine shows that a power coefficient of 0.4 can be achieved. So far, reaching performance levels high enough to compete with the most efficient VAWTs. The D VAWT is still far from full optimization, but the analysis presented here shows the hidden potential and serves as proof of concept. The study of the D VAWT is concluded with a preliminary parametric study of the turbine sensitivity to different incoming wind angles, turbine axes spacing, number of blades, airfoil profile and blade mounting point.
