Robust D-Stability Controller Design for a Ducted Fan Unmanned Aerial Vehicle

This paper deals with the aerodynamic modeling of a small ducted fan UAV and the problem of attitude stabilization when the parameter of the vehicle is varied. The main aerodynamic model of the hovering flight UAV is first presented. Then, an attitude control is designed from a linearization of the dynamicmodel around the hovering flight, which is based on theH ∞ output feedback control theory withD-stability. Simulation results show that suchmethod has good robustness to the attitude system.They canmeet the requirements of attitude control and verify further the feasibility of such a control strategy.
Hazardous Facility Siting When Cost Information is Private: An Application of Multidimensional Mechanism Design

The siting of hazardous facilities often involves externalities that extend beyond the border of the community selected as a site. Thus, the private information of each community is potentially a vector of costs comprising a cost for each of the possible sites. I characterize the conditions for the existence of a direct mechanism that is incentive compatible, individually rational, and budget balancing. Incentive compatibility implies a pattern of compensation payments that often conflicts with compensation policy goals. When nonparticipating communities cannot block the siting of the facility, it will often be possible to implement siting policies with a balanced budget. Copyright 2003 Blackwell Publishing Inc.
Benefits, antecedents, buyer reputation, buyer status and strategic fit in relation to the preferred customer status : a multiple case study at company X and three of its key suppliers

Over the past few years, more attention has been given to the concept of the preferred customer status. Many academics have conducted studies on a theoretical basis regarding this concept, but have rarely studied this concept in a qualitative way. Therefore, this multiple case study is executed to give a qualitative view of the preferred customer status in relation to different concepts. Next to earlier examined concepts such as benefits, antecedents and drivers of the preferred status, new concepts are researched like buyer reputation, buyer status and strategic fit. The results of the multiple case study confirm a large number of earlier discovered benefits, antecedents and drivers of the preferred status, but also add a number of new factors to the literature such as company name and making good appointments. Regarding the three new concepts, several existing factors have been confirmed such as historical legacy, but also new factors have been added to the literature like trust and brand name. The influences of the new concepts on the preferred customer status differ per supplier. However, multiple suppliers argued together with the buying side that buyer reputation, buyer status and strategic fit have an influence on the preferred customer status.
A Dynamic View of Global Integration and Local Responsiveness Framework

Global-Integration and Local-Responsiveness (IR) framework with four pairs of external environment and appropriate international strategy types has contributed significantly to international business management. Nevertheless, the framework is still incomplete and lacks dynamic features. To deal with such limitations and enhance the theory, this paper, therefore, brings dynamic features regarding both environment and strategy into the IR grid. Under a dynamic capability angle with three steps of sensing, seizing and transforming [30], the dynamic global integration and local responsiveness framework – a new concept building for international business – would be explicated.
Research on the key technology of large scale mapping from low altitude photogrammetry

Abstract. Based on the theoretic analysis of the accuracy in large scale photogrammetric mapping, some defects in traditional procedure were discussed. A set of key technologies dedicate to accuracy improvement in low altitude photogrammetry were analyzed in detail, namely the utilization of wide angle camera and low altitude flight, enhancement in image matching, predesigned layout of Ground Control Points (GCPs) in field survey, optimization of adjustment model and improvement in map processing. Besides, a low altitude aerial unmanned airship system was established. Finally, successful implementation in 1:500 topographic mapping project in built-up areas of 30 counties in Shanxi Province proves the practicability and effectiveness of the proposed approaches.
Effects of Enzyme , Growth Promoter , Probiotic and Organic Acid Supplementation to Broiler Diets on Performance and Gut Microflora

In this research, effects of enzyme, growth promoter, probiotic and mixture of organic acids on performance and gut microflora have been examined in 240 day-old Ross 308 broiler chicks. In the experiment, 8 treatments made by supplementation of 3 different additives (Control without additive, growth promoter, probiotic and organic acids and 2 different enzyme levels (O and 0.1 %) in corn-soy based broiler diets have been examined in a 4 x 2 factorial arrangement. Live weight, weight gain , feed consumption, hot carcass yield, mortality and ileal viscosity values has not been s ı gnificantly affected by dietary treatments through the experiment. However, feed conversion ratio was significantly affected by supplementation of enzyme in 0-6 weeks period. Feed conversion results are as follow; 1.898 and 1.845 for the groups without enzyme and with enzyme. Gut microorganism numbers determined 6 1h weeks of age by counting number of aerobic bacteria. total yeast and coliform were found significant (P<0.01) among the groups. The groups received organic acid and arganic acid plus enzyme had lower microorganism numbers than the others (P<0.01) Interaction between type of additives and levels of enzyme was also significant (P<0.01) regarding with microorganism numbers. It could be concluded that enzyme supplementation has improved performance of broilers and also organic acid and organic acid plus enzyme supplementation has decreased the undesired microorganism in the gut while the other treatments had no beneficial efffect in comparison to negative control.

Decision Control and the Pursuit of Binding Conflict Management

International relations scholars have garnered a good deal of evidence indicating that binding arbitration and adjudication are highly effective means for brokering agreements and ending conflict. However, binding third-party conflict management is rarely pursued to resolve interstate disputes over contentious issues like territorial or maritime control. While states value the effectiveness of binding procedures, they are reluctant to give up the decision control necessary to submit to arbitration or adjudication. The authors identify three factors that influence the willingness of states to give up decision control: issue salience, availability of outside options, and history of negotiations. An analysis of attempts to settle territorial, maritime, and river claims reveals that disputants are less likely to use binding conflict management when they have a greater need to maintain decision control.

Perspectives on mucus secretion in reef corals

The coral surface mucus layer provides a vital interface between the coral epithelium and the seawater environment and mucus acts in defence against a wide range of environmental stresses, in ciliary-mucus feeding and in sediment cleansing, amongst other roles. However, we know surpris- ingly little about the in situ physical and chemical properties of the layer, or its dynamics of formation. We review the nature of coral mucus and its derivation and outline the wide array of roles that are pro- posed for mucus secretion in corals. Finally, we review models of the surface mucus layer formation. We argue that at any one time, different types of mucus secretions may be produced at different sites within the coral colony and that mucus layers secreted by the coral may not be single homogeneous layers but consist of separate layers with different properties. This requires a much more dynamic view of mucus than has been considered before and has important implications, not least for bacterial colonisation. Understanding the formation and dynamics of the surface mucus layer under different environmental conditions is critical to understanding a wide range of associated ecological processes.
Analysis of key indicators of economic dimensions of spas' sustainable development in Serbia as tourism destinations.

The purpose of this paper is to analyse the economic indicators of sustainable development of spas in Serbia. The paper starts from the newest division of sustainable development indicators of the tourist destination given by the European Commission. The aim is the ranking of the leading spas in Serbia according to the level of tourism economic sustainability. The following methods are used in the paper: VIKOR method for determining the level of economic sustainability of tourist destination development, and FANMA method for determining the weight coefficients which are necessary for the implementation of VIKOR methods. Based on VIKOR method and starting from the economic indicators of sustainability of the tourist destinations, the leading spas in Serbia are ranked according to the economic sustainability of their development as tourist destinations. The research results indicate to tourism development policy makers to which the spas in Serbia activities should be directed in order to increase the level of their economic sustainable development.
Contact x time External factors and variability in L1 attrition

Investigations of the language behaviour of immigrant communities usually find that the degree of maintenance of the heritage language or shift to the language of the host country differs both between immigrant communities and between individuals. On the one hand, group comparisons between migrants and controls typically show signs of attrition among the experimental populations. On the other, investigations of individual linguistic development within one group of immigrants also show great variation between speakers where the degree of L1 maintenance or deterioration is concerned. Two decades ago, an explanation for such differences in L1 proficiency was proposed which invoked an interaction of two factors: time spent in emigration and amount of contact with the L1. In a study of Dutch migrants in France, De Bot, Gommans & Rossing (1991) established that there was a correlation between attrition effects in free speech and length of residence, but that this effect was only apparent for those speakers who had very little contact with their L1.The present investigation attempts to replicate this finding in a large-scale study of the attrition of L1 German in an L2 English and an L2 Dutch setting. It finds that, while length of residence has no explanatory validity when assessed across the entire population, a differential investigation of subgroups of speakers with different amounts of contact does show an impact of time with respect to performance on formal tasks, perceived foreign accent, and accuracy in free speech. Interestingly, with the exception of accuracy measures, this correlation obtains not only for those migrants who have the least contact with L1, but also for those with the most. It is argued that both very frequent and very infrequent use of the L1 can accelerate attrition, either through contact-induced change within a bilingual migrant community, or through lack of rehearsal.
EFFECTIVENESS OF DIFFERENT MECHANICAL BACTERIAL PLAQUE REMOVAL METHODS IN PATIENTS WITH FIXED ORTHODONTIC APPLIANCE : A SYSTEMATIC REVIEW AND META -

the presence of fixed orthodontic appliances and its accessories tends to affect bacterial plaque removal, resulting in inadequate cleaning being performed by the patient. Thus, the aim of this systematic review and meta-analysis was to answer the following focal question: are the mechanical methods of oral cleaning effective for the reduction of bacterial dental plaque in patients with a fixed orthodontic appliance? A systematic search of the literature was conducted in the following databases: Scopus, PubMed, Cochrane, Web of Science, Embase, and Medline, in addition to Controlled Trials and Grey Literature, without limitations of language and year of publication. Furthermore, searches were also conducted in the reference lists of the articles selected. Included in the present review were clinical studies with patients undergoing therapy with fixed orthodontic appliances, which would, by means of comparison, evaluate the effectiveness of different mechanical bacterial plaque removal methods. The methodological quality of the articles included was evaluated in accordance with the methodological evaluation protocol, and was classified as high, moderate or low. In order to perform the meta-analysis, articles with high methodological quality were included. Analysis of subgroups was performed according to the type of intervention. The plaque index was defined as the continuous outcome variable, using the fixed effect when there was homogeneity among the articles, and the random effect in cases of heterogeneity. 1815 articles were found, of which only 23 fulfilled the eligibility criteria, with 17 being of high methodological quality and 6 of moderate quality. Of these, 18 included an analysis of the effectiveness of the conventional manual brush, 4 of the manual orthodontic brush,15 of electric brushes, 3 of interdental brushes, 1 of dental floss and 4 or oral irrigation devices, and 1 of Siwak. In the qualitative evaluation of the studies, the use of these mechanical control methods was shown to be effective, with exception of the use of Siwak, which presented an increase in bacterial plaque. Moreover, the results of the meta-analysis indicated a significant reduction of -0.98 (IC 95%) in the plaque index for the use of conventional manual brushes in the period of one month (p<0.001). There is a body of evidence that proves the effectiveness of mechanical bacterial plaque removal in patients using orthodontic appliances and accessories. The findings of the meta-analysis proved the effectiveness of the conventional manual brush. Further studies with better standardization of samples are required to strengthen the evidences.
Latest Developments of Negative Sequence Extensions for Generic RMS Models of Wind Turbines

—Generic wind turbine models for grid simulation commonly describe balanced grid conditions only. An extension implementing an active control of negative sequence currents for type 3 (DFIG) and type 4 (full converter) wind turbines is presented that could be used to implement the requirements of specific national grid codes (as required for example in Germany). The negative sequence control model is used for a distribution grid study to show a possible application for the negative sequence control. The results of simulations are compared to measurements from FRT-tests of a wind turbine during unbalanced faults to show the level of accuracy that can be achieved.
Potential role of some nutraceuticals in neurotoxicity induced by aluminum oxide in experimental animal model

The present study aimed to evaluate neurorestorative potential of lecithin (L) and/or gallic acid (GA) in alleviating aluminum (Al)-induced neurotoxicity in rat brain. Rats were classified into seven groups: Group (1): served as control, Groups (2)&(3): received lecithin or gallic acid in a dose of 100 mg/kg body weight. Group (4): received Al in a dose of 300 mg/kg body weight, Group (5): received Al + lecithin, Group (6): received Al + gallic acid and Group (7): received Al + lecithin+ gallic acid. Rats treated orally for 28 days (5days/week). Al induced a significant increase in AChE activity, along with a significant decrease in dopamine (DA), norepinephrine (NE) and serotonin (5-HT) levels. Al treatment resulted in significant increase in malondialdehyde (MDA), nitric oxide (NO) and oxidized glutathione (GSSG) content. On the contrary, Al caused a significant decrease in glutathione (GSH) and GSH/GSSG ratio. As well as, it stimulates an apoptotic signaling program by increase of Bax, caspase-3 and Bax/Bcl-2 ratio accompanied with decrease of Bcl-2 in the tested brain areas. Histopathological examination confirms the biochemical results. Conclusively, treatment with lecithin and/or gallic acid can retrieve the effect of aluminum toxicities on the basis of cholinergic, dopaminergic, oxidative, and apoptotic status.
Late twentieth century Northern Hemisphere sea‐ice record from U.S. National Ice Center ice charts

[1] Arctic sea ice plays a key role in the climate system, by acting as the interface between a warm ocean and a cold atmosphere. Establishing the true pattern of recent behavior of the sea ice in this region is critical to simulating the role of sea ice in future climate. Recently released operational ice charts from the U.S. National Ice Center provide insight into the late twentieth century behavior of Northern Hemisphere sea ice, providing more reliable ice concentrations during summer and freeze-up than those available from the passive microwave record. The major winter and summer modes of ice concentration variability observed from empirical orthogonal function analysis covering the period 1972–1994 are shown to indicate, respectively, the 1-year lagged response of the sea ice to the North Atlantic Oscillation and the winter preconditioning of summer sea ice coverage in the eastern Arctic by the North Atlantic Oscillation. Feedback to the atmosphere is suggested in each case by zero-lag cyclone frequency relationships to these two sea ice modes of variability.
Ramification and unintegrated value distribution.

For a holomorphic map / from the complex plane into the Riemann sphere, the ramification term n x (f,r) is studied. A geometric version of ramification is defined in terms of the intersection points of f(z)X f(z + h) with the diagonal Δ for a suitable vector field h. Estimates of a counting function for this intersection number are given in terms of the mean covering number.
Influence of some geometrical parameters on Piano Key Weir discharge efficiency

The Piano Key Weir (PKW) is a type of labyrinth weir with efficient hydraulic performance, especially at low heads. Since the primary parameters were extensively studied, Electricite De France (EDF) launched a new experimental program to improve the knowledge of some secondary parameters such as the overhangs, the crest shape, and the dam height. This program included the testing of a trapezoidal shape and of PKWs under submerged conditions. The data measured under free-flow conditions were also used to validate empirical correlations and FLOW-3D numerical models. This paper gives an overview of the program and highlights the main experimental and numerical results.
3D BEHAVIOUR OF A 4 PARAMETER ISOTROPIC NONLINEAR HARDENING PLASTICITY MODEL FOR CONCRETE

In general, concrete is a highly nonlinear material with great dependence on the confining stresses, a type of behaviour also common in other granular and quasi-brittle materials. The CEB-FIP Model Code (1) recommends the use of a four-parameter failure criterion to estimate the strength of concrete under multiaxial states of stress. This failure criterion is also known as the Ottosen failure criterion, and it captures with high accu- racy the behaviour of these materials, as demonstrated by several researchers, performing experimental test programs. The concrete strength estimation takes into account, with great precision, the effect of the increase in the confining stresses. In order to simulate the monotonic quasi-static multiaxial behaviour of concrete, one possible strategy is to introduce in this failure criterion a hardening parameter and the corresponding evolution law, under the isotropic behaviour framework. In the present work, the concrete com- pressive strength in the Ottosen failure criterion is assumed as the hardening parameter, and the CEB-FIP Model Code 90 law for the uniaxial nonlinear behaviour of concrete is used to derive the hardening law. In this case, the loading surface is not explicitly de- fined as a function of the hardening parameter, as in the other more common and simpler isotropic models. As a consequence, some difficulties may emerge, mainly of a numerical nature. In this context, the formulation of the model in a thermodynamically consistent framework is presented. The general behaviour of this model is accessed by the simulation of the monotonic multiaxial loading of concrete elements, and its numerical efficiency is discussed.
