Massive MIMO for Connectivity With Drones: Case Studies and Future Directions

Unmanned aerial vehicles (UAVs), also known as drones, are proliferating. Applications, such as surveillance, disaster management, and drone racing, place high requirements on the communication with the drones in terms of throughput, reliability, and latency. The existing wireless technologies, notably Wi-Fi, that are currently used for drone connectivity are limited to short ranges and low-mobility situations. New, scalable technology is needed to meet future demands on long connectivity ranges, support for fast-moving drones, and the possibility to simultaneously communicate with entire swarms of drones. Massive multiple-input and multiple-output (MIMO), the main technology component of emerging 5G standards, has the potential to meet these requirements.

The structure was 19 refined to R1 = 0.0387 using 53 observed reflections [2σ(I) level]. Magnesium and silicon 20 were found to be disordered at the same octahedral site (with a mean bond distance of 1.957 21 Å). Hydrogen was not located in the difference Fourier maps but it is very likely disordered at 22 a half-occupied 4g position. The centrosymmetric nature of the structure of Phase H is 23 examined in relation to that reported for pure δ-AlOOH at ambient conditions (non24 centrosymmetric, P21nm), and the possibility that these two compounds can form a solid 25 solution at least at high pressure is discussed. 26
Model-based Skin Pigment Cartography by High-Resolution Hyperspectral Imaging

The determination of local components in human skin from in-vivo spectral reflectance measurements is crucial for medical applications, especially for aiding the diagnostic of skin diseases. Hyper-spectral imaging is a convenient technique since one spectrum is acquired in each pixel of the image, and by inversing a light scattering model, we can retrieve the concentrations of skin components in each pixel. The good performance of the method presented in this paper comes from both the imaging system and the model. The hyper-spectral camera that we conceived uses polarizing filters in order to remove the gloss effects by the stratum corneum; it provides a high image size of 1120 × 900 pixels, with a thin spectral sampling of 10 nm over the visible spectrum. The acquisition time of 2 seconds is short enough to prevent movement effects of the imaged area, which is usually the main issue in hyperspectral imaging. The model relies on a two-layer model for the skin, and the Kubelka-Munk theory with Saunderson correction for the light reflection. An optimization method enables computing, in less than one hour, several skin parameters in each of the million of pixels. These parameters (blood, melanin and bilirubin volume fractions, oxygen saturation…) are then displayed under the form of density images. Different skin structures, such as veins, blood capillaries, hematoma or pigmented spots, can be highlighted. The deviation between the measured spectrum and the one computed from the fitted parameters is evaluated in each pixel.
Improved Exact String Matching Algorithms Based upon Selective Matching Order and Branch and Bound Approach

In this paper, we propose two improved algorithms for exact string matching problem, which aims to find all the positions i's in a given text where a given pattern occurs. Our algorithms find the optimal selective comparing order of the pattern so that we could have a better performance in the searching phase. To find the optimal comparing order, we adopt the branch and bound approach. Moreover, our proposed algorithm can be combined with other existing exact string matching algorithms to improve the searching efficiency. The experimental results show that our algorithms indeed have the smallest number of character comparisons when comparing with the other algorithms using different comparing order. Besides, our algorithms are also efficient in the running time as compared with other existing exact string matching algorithms.
Iron L 3-edge spectroscopic evaluation of iron oxide and oxy-1 hydroxide coordination 2 Revision 1 3

15 16 The iron (Fe) L2,3-edge X-ray Absorption Near-Edge Structure (XANES) spectrum is 17 sensitive to the local coordination environment around the Fe metal centre, making it a 18 useful probe for understanding Fe mineral speciation. The two dominant spectral peaks in 19 the Fe L3-edge are parameterised according to the difference in the energy position 20 (ΔeV), and the quotient (intensity ratio) of the two peaks’ maxima. Variations in the ΔeV 21 value are strongly linked to factors that impact on the strength of the ligand field (e.g., Fe 22 valence state, coordination number, and the nature of ligand bonding). The intensity ratio 23 is affected by the strength of the ligand field and by the composition of the resultant 24 molecular orbitals. The Fe valence state also strongly affects the intensity ratio, and an 25 intensity ratio equal to one can be used to distinguish between Fe(II) and Fe(III) minerals. 26
The relationship between isokinetic knee flexion and extension muscle strength, jump performance, dynamic balance and injury risk in female volleyball players

The relationship between balance, knee muscle strength, jump height and risk of injury has not been clearly stated in female volleyball athletes. The study was to determine whether a correlation exists between knee joint isokinetic muscle strength, risk of injury, balance and jump height in female volleyball athletes. Twenty-two female volleyball athletes were involved into the study. Knee muscle strength were evaluated with the Biodex 3 ® isokinetic dynamometer. Jump performances were evaluated with the countermovement (CMJ) jump test using the Vert Jump ® Motion Sensitive Sensor. The injury risk for all players were evaluated by the Functional Movement Screen (FMS ® ). Balance measurements were performed with a dynamometer Biodex Systems 3 ® device. There was a significant relationship between CMJ height, knee flexion and extension peak torque and H:Q ratio values at two angular velocities, dynamic balance and total FMS ® scores ( p .05). We suggest that all clinicians and coaches involved in the protective and preventive rehabilitation phase evaluate these parameters and plan their training programs in line with the results obtained in increasing both individual and team performance of athletes.
Learner autonomy , the Common European Framework of Reference for Languages , the European Language Portfolio , and language teaching at university

This paper begins by discussing two versions of the theoretical construct ‘learner autonomy’. Version 1 has played a role in second and foreign language teaching at universities since the 1980s, largely via self-access learning schemes. Version 2 has had far less impact at university level, though it rests on broader theoretical foundations than Version 1. The second part of the paper explains how the Common European Framework of Reference for Languages can be used to develop university L2 curricula informed by learner autonomy Version 2 and how the European Language Portfolio can support their implementation. Although my arguments have general relevance, for the sake of clarity I focus on foreign language degree programmes. In my conclusion I briefly recapitulate the argument of the paper and outline its implications for university L2 examinations and other assessment practices. Two versions of learner autonomy Version 1 The term ‘learner autonomy’ was introduced to the world of language teaching by Henri Holec in Autonomy and foreign language learning, a report commissioned by the Council of Europe and first published in 1979 (cited here as Holec 1981). Holec defines learner autonomy as the ‘ability to take charge of one’s own learning’ (1981: 3): To take charge of one’s learning is to have, and to hold, the responsibility for all the decisions concerning all aspects of this learning, i.e.: determining the objectives; defining the contents and progressions; selecting methods and techniques to be used; monitoring the procedure of acquisition properly speaking (rhythm, time, place, etc.); evaluating what has been acquired. (ibid.) This is Version 1 of learner autonomy. The link between the Council of Europe and learner autonomy is not accidental. The Council of Europe was founded to defend human rights, parliamentary democracy and the rule of law, and its various educational policies and projects have all been concerned in one way or another with education for democratic citizenship. In the 1970s it promoted adult education and adult language learning as instruments of democratization, believing that whatever was learnt should enhance the learner’s capacity to contribute to the democratic process. In another Council of Europe report of the 1970s, Janne argued that adult education should be an instrument for arousing an increasing sense of awareness and liberation in man, and, in some cases, an instrument for changing the environment itself. From the idea of man ‘product of his society’, one moves to the idea of man ‘producer of his society’. (Janne 1977: 15) This ideal should be reflected in the teaching/learning process itself: the aim of the Council of Europe’s policy in regard to adult language learning, for example, was to
THE EXPERIENCE OF APPLYING A QUALITATIVE METHOD IN A HOSPITALITY RESEARCH

There are many ways of collecting data for performing research in the hospitality industry. Many researchers in this area are using both qualitative and quantitative approach to collect data for their relevant studies. However, the chosen method needs to be suited with what researchers need to find out and what kind of study they perform. Generally research can be classified as either an academic research and/or applied research. The former addresses new ideas and fundamental knowledge lead to new theories and the latter provides and stimulates interests to an industry practitioner. This paper explains one way of collecting data using a qualitative approach in the hospitality industry. To obtain qualitative data, an in-depth interviewing was utilized to critically investigate the perception of the industry practitioners towards the usage of the Internet as a marketing tool. Series of semi-structured interviews were conducted with the hotel managers at Langkawi Island to discuss issues such as online marketing strategies and their effectiveness in marketing hotel products and services to a global market. In the case of Langkawi’s hotel industry, there are factors such as hotel type, star rating, location and target markets that influence the uses of the Internet within hotels and resorts. There are few issues highlighted in the paper in terms of getting hotel managers to participate in this study, finding the suitable time for collecting data and convincing the owner or manager the value of this research. Working with hotel managers and interviewing them for the topic investigated are the most exciting process but yet very challenging. It is strongly felt that researchers need to work collaboratively with the practitioners to gain new knowledge and experience for the benefits of the hospitality industry.
University of Verona Bayesian Kantorovich Deconvolution in Finite Mixture Models

This chapter addresses the Bayesian approach to the problem of recovering the latent or mixing distribution in finite general kernel mixture models, when the number of components is unknown, yet bounded above by a fixed number. Taking a step back to the historical development of the analysis of this problem within the Bayesian paradigm and making use of the current methodology for the study of the posterior contraction phenomenon, we show that, for general prior laws supported over the space of mixing distributions with at most a fixed number of components, under replicated observations from the mixed density, the mixing distribution is estimable in the Kantorovich or L-Wasserstein metric at the optimal frequentist rate n−1/4 (up to a logarithmic factor), n being the sample size.
Prioritization of Balatira Watershed by Morphometric and Landuse Landcover Analysis , Atpadi Taluka , Sangli District , Maharashtra

Today the world is facing the biggest crisis of water. The available both surface and groundwater resources are not sufficient to the water requirements for all purpose. Remote Sensing and Geographical Information System have emerged to meet ever increasing demand for more precise and timely information. These techniques permit rapid and cost effective natural resource survey and management. The morphometric analysis of the drainage basin and channel network play an important role in understanding the geohydrological behaviour of drainage basin and is manifestation of the prevailing climate, geology, geomorphology, hydrology, structure and land cover of the catchment area. In the present study, morphometric analysis and land use / land cover analysis has been carried out using Geographical Information System (GIS) techniques to assess the geo-hydrological characteristic of Balatira drainage basin. Balatira watershed falls in Atpadi taluka, Sangli district, Maharashtra and covers an area of 278 Km 2 . The morphometric analysis of watershed has been carried out using GIS softwares – Arc-GIS 10.0 and Arc View. An attempt has been made to identify the groundwater potential zones through geomorphometric aspects. Drainage analysis based on morphometric parameters is important for watershed planning since it gives an idea about the basin characteristics in terms of slope, topography, soil condition, runoff characteristics, surface water potential etc. The development of landforms and drainage network depends on bed rock lithology and associated geological structures. GIS techniques were used for assessing various morphometric parameters of Balatira drainage basins as it provides a flexible environment and an important tool for the manipulation and analysis of spatial information.
1 Disposal of High-Level Nuclear Waste in Deep 2 Horizontal Drillholes 3

Spent nuclear fuel and high-level radioactive waste can be disposed in deep horizontal 14 drillholes in sedimentary, metamorphic, or igneous rocks. Horizontal drillhole disposal has safety, 15 operational, and economic benefits: The repository is deep in the brine-saturated zone far below 16 aquifers in a reducing environment of formations that can be shown to have been isolated from the 17 surface for millions of years; its depth provides safety against inadvertent intrusion, earthquakes, 18 and near-surface perturbations; it can be placed close to the reactors and interim storage facilities, 19 minimizing transportation; disposal costs per ton of waste can be kept substantially lower than for 20 mined repositories by its smaller size, reduced infrastructure needs, and staged implementation; 21 and, if desired, the waste could be retrieved using “fishing” technology. In the proposed disposal 22 concept, corrosion-resistant canisters containing unmodified fuel assemblies from commercial 23 reactors would be placed end-to-end in up to 50 cm diameter horizontal drillholes, a configuration 24 that reduces mechanical stresses and keeps the temperatures below the boiling point of the brine. 25 Other high-level wastes, such as capsules containing 137Cs and 90Sr, can be disposed in small26 diameter drillholes. We provide an overview of this novel disposal concept and its technology, 27 discuss some of its safety aspects, and compare it to mined repositories and the deep vertical 28 borehole disposal concept. 29
FATTY AND LEAN PIGLETS ESTABLISH EARLY DIFFERENCIATION IN DNA , RNA AND PROTEIN RETAIN : COMPARATIVE TRIAL ON ALENTEJANO BREED vs . CROSSBRED PIGLETS

1 Instituto de Ciências Agrárias e Ambientais (ICAAM) Universidade de Évora, Apartado 94, 7002-554 Évora, Portugal, e-mail: jnunes@uevora.pt AbStrAct The aim of this trial was to compare protein, DNA and RNA concentrations in muscle samples from Alentejano piglets (AL) versus Large-White Landrace crossbred piglets (C), since DNA-RNA interrelations and the relations of each parameter with the protein, can serve as indicators for the number of muscle cells and the ability to synthesize protein. The Alentejano swine breed carcasses are characterized by offering a high fat/muscle ratio, consequently it is important to determine the reasons of the relatively small proportion of muscle in the carcass. Samples were taken from longissimus dorsi muscle (LD) of 6 Alentejano piglets (AL) and 6 crossbred piglets (C) slaughtered at 21 days of age. DNA, RNA and protein concentrations were determined. The LD samples from AL piglets showed lower concentration in the DNA compared with C piglets (131.87 ± 10.50 mg/100 g vs. 169.38 ± 10.50 mg/100 g; P < 0.05). However, the LD from AL piglets presented greater concentration of RNA (180.50 ± 11.25 mg/100 g vs. 134.00 ± 11.25 mg/100 g; P ≤ 0.01) and protein (22.41 ± 0.83 vs. 18.91 ± 0.83 g/100g; P ≤ 0.01) when compared to the LD from C piglets. The RNA/ADN and Protein/DNA relations were also significantly higher (P < 0.01) in samples of muscle from AL piglets. These results indicate a lower number of muscle cells in the LD of AL piglets however, the situation reversed when capacity for synthesis was considered.
Monetary Policies under the EMS . An Empirical VAR Approach . 1

This paper proposes an empirical framework to analyse monetary policies in a small open economy under xed exchange rates. First, the analysis proposes a semi{restricted VAR model with the lowest number of restrictions to focus on the e ects of the center{country and the Rest{of{the{World monetary policies. Next, we use a fully structural VAR approach where the identifying restrictions are imposed on the short{run behavior of the variables. The model is applied to the EMS experience of France, Italy and the Netherlands by considering Germany as the center country and the US as the Rest of the World. The presence of imperfect capital mobility allows us to attribute partial monetary independence to the domestic monetary authorities. Innovations in the German monetary policy are found to be highly important for the Dutch monetary policy, but much less for France and especially for Italy. Instead, the US shock plays a particularly relevant role for the French monetary policymaking. There is also evidence of stronger recessionary impact of restrictive German monetary policies on France and Italy rather than the Netherlands. This may explain why the former two countries devalued so many times. JEL Classi cation: F33, F41, F42.
The Inevitability of Price Spikes and Tight Capacity in Competitive Electricity Markets

Underinvestment in generation capacity and price volatility in competitive electricity markets are major concerns to policymakers in the USA and Europe. Using a two-stage decision model describing a competitive electricity market with endogenous capacity and operations, and with two generating technologies and uncertain demand, this paper shows that both price volatility and tight generation capacity in deregulated electricity markets are closely related, inevitable, and result from the optimal (non-abusive) behavior of market participants. This paper presents easy-to-use conditions for the existence and uniqueness of the solution of the model and shows that the probability of a price spike increases when the capacity cost of the peaking technology rises, decreases when the volatility of demand increases, and is independent of the number and distribution of producers in the market. The theoretical predictions of the model are illustrated by applying it to the Israeli electricity market.
Molecular phylogeny and classi fi cation of Lyropaeini ( Coleoptera : Lycidae ) with description of larvae and new species of Lyropaeus

The generic classifi cation of Lyropaeini is revised on the basis of molecular phylogeny. Two lineages mark the basal split of Lyropaeus Waterhouse, 1878: the Indian-Sri Lankan-Vietnamese clade (subgenus Lyropaeus s. str.) and the East Oriental clade (subgenus Lyroneces Kazantsev, 1998). Lyroneces is demoted to a subgenus of Lyropaeus due to the absence of reliable morphological characters. Lyropaeus bicolor Pic, 1911 (Java), L. binotatus Pic, 1926 (Java), L. longipennis Pic, 1911 (Java), L. philippinensis Kleine, 1926 (Philippines), L. ritsemae Gorham, 1882 (Sumatra), and L. waterhousei Gorham, 1882 (Sumatra) are placed in the subgenus Lyroneces Kazantsev, 1998. Paralycus Medvedev & Kazantsev, 1992 is a junior homonym of Paralycus Womersley, 1944 (Acari). The larvae of three Lyropaeus species are described and compared with neotenic larvae of Platerodrilus Pic, 1921. The independent origins of large-bodied neotenic larvae are hypothesized in Lyropaeus and Platerodrilus and the molecular evidence is supported by the differences in morphology. Two new Lyropaeus species are described: Lyropaeus (s. str.) kejvali, new species (India: Kerala), and L. (s. str.) nepalensis, new species (Nepal).
1 A Framework for Spatial Interestingness Scoping of a Performance Variable in Different Contexts

Predicting if a particular user clicks on a particular Ad is of critical importance for Internet advertizing. Associations between the Internet Ad’s Click Through Rate, CTR, and demographic data may be very weak on the global level but are strong at the regional level. Identifying such regions with strong associations of a continuous performance attribute with other factors is important for geo-targeted advertising. In this paper, we propose a novel framework for interestingness scoping to identify such regions by iteratively merging zip code areas, maximizing a plug-in, userdefined interestingness function. We applied our framework to a geo-spatial data set, combining data from a major Ad network and demographic data from the 2000 Census. In the experimental results, our framework found strong global associations between CTR and educational level, and regions of strong positive and negative associations between CTR and income that do not exist globally. Given that the behavior of the population is the driving force determining CTR, it follows that those regional variations in population demographics would account for differences with respect to CTR in those regions. These results can, in turn, be utilized by the Ad provider to improve its geo-targeted advertising in those regions.
