THE LINK BETWEEN OPERATIONAL PERFORMANCE AND OPERATIONAL ERRORS IN THE NATIONAL AIRSPACE SYSTEM

We consider the link between the incidence of operational errors (OEs), operations counts, operational conditions, and weather in the US National Airspace System (NAS). Our main aim is to test the hypothesis--suggested by the human factors literature linking cognitive tasks and human error-that adverse operating conditions lead to higher rates of OEs. Poisson regression estimation results support this hypothesis in all three air traffic control domains—en route, tower, and TRACON. Our results also demonstrate that OEs increase supralinearly with operations volume, that convective weather causes more TRACON and en route operational errors, that low visibility increases tower OEs, and that there are large facility fixed effects for TRACON and tower OEs. One implication of this research is that investments to improve operational performance of the NAS may also improve its safety performance.

The dielectric resonator antenna is fabricated on a cheap FR4 substrate with grounded CPW (GCPW) structure. A new closed circular loop GCPW slot structure is employed to obtain wideband impedance matching. Results of the designed dielectric resonator antenna show that good agreement between simulated and measured reflection coefficients, radiations, and antenna gains is observed. The measured -10 dB bandwidth of the dielectric resonator antenna is 1.6 GHz (28.5%, 4.8 – 6.4 GHz), which covers the WLAN 5.5 GHz band. Index Terms ─ Dielectric resonator, DRA, GCPW, wideband, WLAN.
MICROSTRUCTURE , STRENGTH , ELECTRICAL CONDUCTIVITY AND HEAT RESISTANCE OF AN Al-Mg-Zr ALLOY AFTER ECAP-CONFORM AND COLD DRAWING

This paper describes the routes to process conducting materials based on the Al-MgZr system combining high strength (UTS=267 MPa), electrical conductivity (over 57% IACS) and heat resistance (up to 150°C). These properties in the alloy with 0.4 wt. % Mg and 0.2 wt. % Zr are achieved through the formation of ultrafine-grained microstructure (UFG) by thermomechanical treatment (TMT), including annealing, severe plastic deformation (SPD) via equal channel angular pressing-Conform (ECAP-C) followed by cold drawing. The mechanical strength is enhanced by the formation of ultrafine grains during ECAP-C and their additional refinement through cold drawing. Also, ECAP-C and drawing result in the material strengthening due to increased dislocation density. The annealing of the alloy prior to SPD is used to provide a good heat resistance and high electrical conductivity via formation of nanoscale Al 3 Zr metastable precipitates and, correspondingly decreasing the concentration of Zr atoms in the Al solid solution.
BDNF AND ANDROGEN INTERACTIONS IN SPINAL NEUROMUSCULAR SYSTEMS

Neurotrophic factors and steroid hormones interact to regulate a variety of neuronal processes such as neurite outgrowth, differentiation, and neuroprotection. The coexpression of steroid hormone and neurotrophin receptor mRNAs and proteins, as well as their reciprocal regulation provides the necessary substrates for such interactions to occur. This review will focus on androgen-BDNF interactions in the spinal cord, describing androgen regulation of BDNF in neuromuscular systems following castration, androgen manipulation, and injury. Androgens interact with BDNF during development to regulate normally-occurring motoneuron death, and in adulthood, androgen-BDNF interactions are involved in the maintenance of several features of neuromuscular systems. Androgens regulate BDNF and trkB expression in spinal motoneurons. Androgens also regulate BDNF levels in the target musculature, and androgenic action at the muscle regulates BDNF levels in motoneurons. These interactions have important implications for the maintenance of motoneuron morphology. Finally, androgens interact with BDNF after injury, influencing soma size, dendritic morphology, and axon regeneration. Together, these findings provide further insight into the development and maintenance of neuromuscular systems and have implications for the neurotherapeutic/neuroprotective roles of androgens and trophic factors in the treatment of motoneuron disease and recovery from injury.
Image Steganography Method for Hiding Secret Message in Colored Images by Using IWT

Steganography is a medium to hide the secret message in such a way that only sender and receiver only know about it. No other one on network cannot suspects the existence of the message. The proposed paper represents here a image steganography method for hiding secret message in colored images by using integer wavelet transform. Steganography method is provides more security to images that contain secret message. The proposed techniques uses the LSB technique.

Regionalism temp

The last decade seen escalation of regional and bilateral trade agreements. Many view regionalism as being a counter to the move to foster rapid multilateralism. However, one could justify this striking proliferation to the reduced momentum of multilateral negotiations. Based on this logic, it makes sense to explore various viewpoints. The contrasting perspectives range from thinking of regionalism as a stumbling block to one that thinks it as being a building block for rapid growth in multilateralism. In the same vein would be the consideration whether regionalism is trade-creating or trade-diverting. The rapid build-up of the RTAs may have affected the negotiating dynamics of the Doha Round of negotiations under the World Trade Organisation (WTO) and it is unclear whether the increase in bilateral deals is in response to the slow progress of Doha talks. Concerns over the RTA expansion played a role in the launch of the Round, and, after the failure of the Cancun ministerial, it has gathered momentum . The divide between the developed and the developing world is being driven by the inability to arrive at a consensus on issues relating to agriculture. The split has been seen in the nature of a North-South polarisation and the characteristic movement of regional and bilateral trading formats is being declared, or announced, virtually on a daily basis. In this Paper, an attempt is being made to understand the entire gamut of issues connected with regionalism. It will try to look at the issue in the perspective of a rule-based global trading environment. Regionalism will be explained in the context of the legitimacy that the GATT and the WTO provide and whether it has a positive impact on the economy. What is Multilateralism?
PEAK NEGATIVE PRESSURE COEFFICIENTS ON LOW-TILTED SOLAR ARRAYS MOUNTED ON FLAT ROOFS : THE EFFECTS OF BUILDING SIZE AND MODEL SCALE

Pressure coefficients corresponding to peak uplift on low-tilted solar panels mounted on flat-roofed buildings were determined based on boundary layer wind tunnel testing. The solar panels were arranged in arrays of 8 panels by 12 rows. A total of 9 array positions on a total of 11 buildings of different sizes with sharp roof edges were studied. The testing was conducted on a geometrical scale of 1:100 with parts of the testing being repeated at a larger scale of 1:50. Significant effects of array location on the roof, row and panel position within the array, tributary area and building size on peak negative pressure coefficients were found. A refined method for plotting pressure coefficients over normalized tributary area is proposed. In addition, it is shown that at a model scale of 1:50 peak negative pressure coefficients are higher for all array positions and building sizes. This finding may partly be associated with the effects of additional high-frequency turbulence which is not present at the smaller 1:100 scale.
The morphology and mechanism of formation of SiC in C / CSiC composites fabricated by liquid silicon infiltration

Carbon fibre reinforced carbon and silicon carbide dual matrix composites (C/C-SiC) are a new type of high performance brake materials. In the present study, C/C-SiC brake composites were fabricated by the combination of chemical vapor infiltration (CVI) with liquid silicon infiltration (LSI). Results show the composite is composed of 55%C, 39% β-SiC, and 6% Si. There exist two different areas of SiC, one zone of coarse micro-β-SiC grains between 5 and 20 μm at the SiC/silicon interface, and this zone usually forms inside the porosity of the carbon fibre reinforced carbon (C/C) preform such as around the fibres and among the C/C bundles. The other zone consists of fine nano-SiC particles with dimensions of 100-800 nm at the pyrocarbon/carbon fibre interface. From these observations, reaction mechanisms governing the siliconization of porous C/C preform are proposed. After an initial reaction of carbon with liquid silicon, an initial continuous SiC layer formed on the silicon/pyrocarbon interface, and the subsequent formation of SiC is controlled by diffusion of carbon atoms and/or silicon atoms through the already formed SiC layer.
Media and Information Literacy among Macau University Students : An Initial Study

Recent research has emphasized the importance of media and information literacy among university undergraduate and graduate students with respect to the high demand on these critical thinking skills. The current study extended three scales for measuring these two literacies, including the Media Literacy Self-assessment Scale, the Competence Information Literacy Questionnaire, and the UNESCO Information Literacy Lifecycle, into Chinese culture with a Macau sample. The aims were to investigate the self-perception of these literacies of students from University of Macau, and the factors that may influence these self-perceptions. Result revealed that: first, gender has no effect on the level of media and information literacy; second, participants who own digital devices tended to have higher self-perceived score on media literacy; and third, participants at Master’s Year 2 level showed significantly higher self-perceived scores on the UNESCO information literacy lifecycle. Findings from this study help educators and school policy makers to gain insights on the way to enhance students’ media and information literacy in the 21st century and therefore, in the future.
H ET MR : Hybrid Deployment of MapReduce Jobs on Heterogeneous Hardware

Cloud providers offer access to hardware accelerators, such as FPGAs and GPUs, according to a pay-per-use model. Data-parallel processing frameworks, such as MapReduce, make it easy for users to express parallel jobs, but an open challenge remains how such jobs can exploit accelerators in a cloud setting. While dedicated MapReduce frameworks for specific accelerators exist, users lack decision support on when accelerators can deliver substantial benefit for their jobs. We observe that the performance improvement attained by accelerators, if any, is dependent on both the data and the phase (map or reduce) of the MapReduce job. Based on a generalised model of shared-memory MapReduce, we describe HETMR, a MapReduce framework that can execute jobs in a hybrid fashion across CPUs and accelerators. While previous attempts at a hybrid solution simply allocate portions of job data to full MapReduce implementations residing on the CPU and accelerator, HETMR instead assigns a phase to each device and provides a means to move the data between the two. To avoid unnecessary accelerator costs and determine the best phase assignment, HETMR first profiles the MapReduce job on the CPU, yielding a measure of potential speedup. Depending on the outcome, it then deploys the job in either a CPU-only or hybrid fashion by drawing on a library of designs. Our experimental evaluation shows that HETMR’s hybrid execution model improves job completion by up to 6 times with an FPGA.
TREATED BY LASER RECANALIZATION THERAPY : CASE REPORT

Bronchology has a background of approximately a century. During the next 80 years its indication was just limited to foreign body removal. Since 1980’s, indications of therapeutic bronchoscopy have been expanded owing to widespread use of laser systems in medical and surgical fields [1]. Today, bronchoscopic laser therapy is applied in many benign and malignant tracheobronchial stenoses. Endobronchial laser therapy is rapid, safe, and complementary to other treatments. It is well tolerated and repeatable as well. Endobronchial laser recanalization provides effective palliation in malignant diseases when surgical therapy can not be performed [2-4]. In benign tracheobronchial stenoses it is curative method that obviates the need of surgical operation. In tracheobronchial stenoses it should be accepted as the method of choice when mortality and morbidity risks of surgical operations are considered. Especially in recurrent obstructive lesions of central airways since surgical procedures are not repeatable. For this reason, therapeutic bronchoscopic methods are the only treatment modalities [5]. In this article, we discussed a 50 year-old male patient with a recurrent endobronchial thymoma after surgical operation, who underwent endobronchial laser recanalization seven times in a three years period, and the results of laser treatment was evaluated.
3 D FACE IDENTIFICATION AND RECONSTRUCTION WITH RANGE SENSOR 1

A method of data augmentation for 3D face model and using it for 3D face identification is proposed in our work. In the past few years, researchers had achieved significant progress on 2D face identification and verification through neural network approaches, such as VGG (Visual Geometry Group) Face, GoogleNet Inception, and ResNet (Residual Network). Since there are so many hyper parameters that need to be optimized in neural networks, large data must be provided for training. In 2017, FaceID was proposed by Apple Inc. Face identification has been scaled up from 2D to 3D. However, training a 3D face classifier is difficult. 3D face datasets nowadays are so small that even a large set of 3D faces contains only 4,666 faces of 105 identities. In order to solve the lack of data, we use transfer learning [13], and several data augmentation methods by generating face mesh from different views to make the classifier more robust and discriminative.
FDI-assisted development in the light of the investment development path paradigm : Evidence from Central and Eastern European countries

Some forms of foreign direct investment (FDI)-assisted development strategies have been widely adopted among developing and transition economies. The Central and Eastern European countries (CEECs) are an interesting case because of the surge of inward FDI over the past decade and the recent increase in outward FDI from the region. But the uneven distribution of FDI among the CEECs raises a question as to whether and to what extent the CEECs are converging in terms of FDI-assisted development path with the EU15 countries, and with each other. The analysis in this study is based on the investment development path (IDP) framework. First, a cluster analysis is used to divide the CEECs into more homogeneous groupings. Econometric and statistical analyses are then carried out to delineate the different IDPs followed by the CEECs. The results indicate that (i) the position of the CEECs is at stage one or two of the IDP; (ii) the CEECs are diverging from EU15 in terms of outward investment position but converging in terms of GDP; (iii) the IDPs within the five sub-groups are converging, and (iv) less developed CEECs are converging with more developed CEECs in terms of outward investment position but not in terms of GDP.
Nonstationary Frequency Content of Ground Motions From The 2011 Tohoku Earthquake in Japan

The 2011 Tohoku earthquake (Mw9.0) and tsunami caused severe casualties,loss of property and destroy of natural environment. After this earthquake, nearly 700 strong ground motions were released by the K-NET of National Research Institute for Earth Science and Disaster Prevention (NIED). For earthquake engineering, timely and effectively processing these ground motion records and comprehensively summarizing their characteristics and rules, can not only reveal the source mechanism of this earthquake, but also help to renew our existing knowledge of devastating earthquake. In this paper, the non-stationary frequency content of ground motions is investigated based on the instantaneous frequency of ground motion. First, an exponential decay model is used to describe the instantaneous frequency and optimization algorithm is used to determine the model parameters. Then, the multidimensional correlation and attenuation relations of model parameters are analysed. Lastly, the analysis results are compared with those of 2008 Wenchuan earthquake (Mw7.9) to demonstrate some unique properties of these mega earthquakes.

Localization is an important objective to be achieved a network of wireless sensor as it has a numerous nodes which are distributed randomly in the network and do not know about their own position. Different techniques are available to be used as distance and position estimation. In this paper a succinct survey on MDS based localization techniques are presented along with their problem and future work.
Fresh , Mechanical and Permeability Properties of Self Compacting Concrete with Recycled Concrete Aggregate

The objective of this research is to evaluate the effect of the incorporation of coarse recycled concrete aggregate, on the properties of self compacting concrete. The effects of such incorporation on fresh, mechanical and permeability properties were investigated and are discussed. Two different series of concrete mixes (i.e. 30 Mpa and 40 Mpa) were prepared to test these properties. In each series, six concrete mixes with replacement ratios of 0%, 20%, 40%, 60%, 80% and 100% of natural coarse aggregate by recycled concrete aggregates were adopted. Results obtained show that self compacting concrete with recycled concrete aggregate exhibits adequate performance. However with increasing replacement of NCA the performance of concrete decreased but at higher strengths it shows improvement in all properties.
Mécanismes moléculaires de la tolérance aux opiacés et aux cannabinoïdes Molecular mechanisms of tolerance to opioids and cannabinoids

MOTS CLÉS Opioïdes ; Cannabinoïdes ; Récepteurs couplés aux protéines G ; Désensibilisation ; Tolérance Résumé Les parallèles entre opiacés et cannabinoïdes sont nombreux. En effet, ces substances exercent leurs effets pharmacologiques sur des récepteurs couplés aux protéines G et sont capables de réguler de la même manière de nombreux effecteurs intracellulaires. De plus, l’utilisation de ces substances, en particulier dans le domaine du traitement de la douleur (depuis longtemps pour les opiacés et en plein développement pour les cannabinoïdes), se heurte à un problème majeur qui est la survenue d’une tolérance lors d’un traitement prolongé. Un des mécanismes à l’origine de cette tolérance serait l’existence d’une désensibilisation des récepteurs. Cette revue va donc s’attacher à décrire les mécanismes moléculaires mis en jeu dans la désensibilisation et à montrer comment les progrès réalisés sur la compréhension de ces mécanismes ouvrent de nouvelles perspectives thérapeutiques. © 2009 Société de réanimation de langue française.

Dominican Spirituality

or the most part people live by stories. I myself live by my own story. When I became a Dominican I linked my life story with the family Story of the Dominicans; as a result, my life story took on a new orientation and I picked up the thread of the story of the Order in my own way. So my own life has become part of the Dominican family story: a chapter in it. Through the story of the Order I have attained my own identity. Stories of the Dominican Order keep us together as Dominicans.
Composition of web applications in clouds environment

In recent years, for the advances of Cloud Computing technologies, cloud applications have been popularity for their rich set of features. The advantages of cloud applications include that users can utilize them in a low cost, threshold, and risk way; these applications can be quickly deployed on the clouds without duplication of work such that developers can focus on enhancing their QoS to improve core competitiveness. Therefore, their practical use on business with promising values can be expected. As such, cloud applications are recognized as a trend for the next generation of business applications, and hence how to migrate these onpremise applications to the clouds becomes a desired field in the literature. For this need, we present an ontology-based method for the composition process that specifically addresses the cloud features and the composition of on-premise applications into the clouds. In particular, for enabling the selection of desired clouds, the method imposes semantic ontologies on the specifications of the candidate clouds from which the desired ones can be effectively selected. For illustration, the method is applied to the composition of a CSS application to its cloud version.
