Airfoils for wind turbines have been selected by comparing data from different wind tunnels, tested under different conditions, making it difficult to make accurate comparisons. Most wind tunnel data sets do not contain airfoil performance in stall commonly experienced by turbines operating in the field. Wind turbines commonly experience extreme roughness for which there is very little data. Finally recent tests have shown that dynamic stall is a common occurrence for most wind turbines operating in yawed, stall or turbulent conditions. Very little dynamic stall data exists for the airfoils of interest to wind turbine designer. In summary, very little airfoil performance data exists which is appropriate for wind turbine design.

The authors describe the structure, formation and interpretation of 35 different string figures (fafoa) made among the Wampar (Morobe province, Papua New Guinea). The string figures were recorded in 2003/4 and 2013, from families of the village of Gabsongkeg. Aspects of the context in which the string figures occur are described. Placed in a comparative perspective, the Wampar string figure repertoire reflects the various relations that existed and exist with neighboring and more distant ethnic groups in Papua New Guinea. Two of the string figures have (until now) only been recorded among the Wampar, while three have been recorded only among the Wampar and their neighbors, the Watut. Nowadays rapid social change often occurs in the communities of Papua New Guinea, and this is certainly true of the Wampar. The making of string figures now competes with several alternative pastimes. This has led to changes in the string figure tradition, yet the material presented in this paper does not support the conclusion that the repertoire is diminishing or that the tradition will die out soon. Wampar string figures (fafoa) have been documented by Hans Fischer over a remarkably long period (Fischer 2010, 2012). Since the 1950s he has taken pictures, made drawings of the final figures and asked for their names and their meanings. Bettina Beer added to this corpus in the course of more recent research. This article aims to describe the repertoire of Wampar string figures, discuss aspects of its change over time and to contextualise it with material

The marine benthic green and brown macroalgae of Rodrigues, collected during an expedition in October 2001, are documented and 18 of the 60 taxa of Chlorophyta (53 species) and 18 species of Phaeophyceae are illustrated. Fifty taxa of green and 12 taxa of brown algae are added to the existing species list of the island. Turf algae and smaller epiphytic species are not or are only sporadically included in this study. All records are listed with bibliographic, biogeographic, taxonomic and nomenclatural comments. Infrageneric identification keys are included. The new combination Caulerpa mexicana var. exposita is proposed and the discovery of a new Udotea species is mentioned. The algal flora of Rodrigues is of a typical Indian Ocean composition but appears to be relatively poor when compared to the nearby island of Mauritius.

Many electric circuits are complex, but it is an engineer's goal to reduce their complexity to analyze them easily. In the previous chapters, we have mastered the ability to solve networks containing independent and dependent sources making use of either mesh or nodal analysis. In this chapter, we will introduce new techniques to strengthen our armoury to solve complicated networks. Also, these new techniques in many cases do provide insight into the circuit's operation that cannot be obtained from mesh or nodal analysis. Most often, we are interested only in the detailed performance of an isolated portion of a complex circuit. If we can model the remainder of the circuit with a simple equivalent network, then our task of analysis gets greatly reduced and simplified. For example, the function of many circuits is to deliver maximum power to load such as an audio speaker in a stereo system. Here, we develop the required relationship betweeen a load resistor and a fixed series resistor which can represent the remaining portion of the circuit. Two of the theorems that we present in this chapter will permit us to do just that.

Scalability is an important issue in object recognition as it reduces database storage and recognition time. In this paper, we propose a new scalable 3D object representation and a learning method to recognize many everyday objects. The key proposal for scalable object representation is to combine the concept of feature sharing with multi-view clustering in part-based object representation, in particular a common-frame A c c e p t e d m a n u s c r i p t constellation model (CFCM). In this representation scheme, we also propose a fully automatic learning method: appearance-based automatic feature clustering and sequential construction of clustered CFCMs from labeled multi-views and multiple objects. We evaluated the scalability of the proposed method to COIL-100 DB and applied the learning scheme to 112 objects with 620 training views. Experimental results show the scalable learning results in almost constant recognition performance relative to the number of objects.

Two large bolted steel moment-resisting connections were studied by experiments. These connections were single-sided beam-column assemblies that are representative of exterior beam-column connections. They were composed of W36x150 Grade 50 beams and W14x257 Grade 50 columns. T-sections were cut from W40x264 sections of Grade 50 steel. The T-section webs were welded to the beams and prestressed by bolts to the beam flanges in the shop. Final beam-to-column assembly required no additional welding: the T-section flanges were bolted to the column and the column shear tab was bolted to the beam web. The specimens had two symmetrically located T-sections with different web geometry: Specimen 1 had rectangular-shaped webs, whereas Specimen 2 had U-shaped webs. During cyclic testing beam deformation was minimal due to active participation of the T-section flanges: a separation between T-section flanges and the column flanges was observed. This separation occurred due to bending plastic deformation in the T-section flanges. This phenomenon allowed dissipating energy and prevented severe buckling in the beam flanges and beam web. iv ACKNOWLEDGMENTS

This report comprises four chapters. The first chapter unfolds citizens’ perceptions on national security concerns. The second chapter elaborates citizens’ perceptions on public safety. Consequently, the third chapter interrelates citizens’ perceptions toward public safety concerns with reality, while examining the reasons that may have influenced these perceptions. Meanwhile, the last chapter offers a range of recommendations, measures to be taken into consideration, in order to improve public safety in Kosovo. Various elements affect citizens’ perceptions regarding public safety. Indisputably, such attitudes are shaped by personal experiences. However, the importance of media and social networks in shaping citizens’ opinions cannot be ignored. Perceptions might be correlated with personal characteristics such as age, gender, ethnicity, education and economic status. Therefore, beyond general data analyses, this edition also includes cross-analyses of various public security threats with personal characteristics.
