Modern UAVs available in the market have well-developed to cater to the countless field of application. UAVs have their own limitations in terms of flight range and manoeuvrability. The traditional fixed-wing UAVs can fly for long distance but require runways or wide-open spaces for take-off and landing. On the other hand, the more trending multirotor UAVs are extremely manoeuvrable but cannot be used for long-distance flights because of their slower speeds and relatively higher consumption of energy. This study proposed the implementation of hybrid VTOL UAV which has the manoeuvring advantage of a multirotor UAV while having the ability to travel fast to reach a further distance. The design methodology and fabrication method are discussed extensively which would be followed by a number of flight tests to prove the concept. The proposed UAV would be equipped with quadcopter motors and a horizontal thrust motor for vertical and horizontal flight modes respectively.

This chapter explores how the analyses of audible infrastructures presented in this volume connect to the established and growing body of literature on civic infrastructures from scholars in the humanities and social sciences. There are clearly convergent interests between those who work on roads, water, and energy systems, on the one hand, and those who study the production, circulation, and reproduction of sound, on the other. To analyze the materialities of music making, as with civic infrastructures, is to investigate the relational capacities of the materials from which things are made, the diverse types of labor through which these materials become integral to their emergent forms, and the uneven distribution of access to the wider structures that underpin the circulation and reproduction of such forms. In particular, the chapter focuses on how the relationship between the hardware of engineered systems and the software of sociality creates new possibilities for thinking about the politics of infrastructure. The chapter explores these resonances between audible and civic infrastructures by considering the M1 Symphony, a work commissioned by the British Broadcasting Corporation to mark the sixtieth anniversary of the opening of Britain’s first long-distance motorway. The example provokes reflection on the relationship between media and infrastructure, between composition and improvisation, and between ontological experiment and artful design.

The aim of this study was to investigate whether human infants' cries show individually and contextually discriminable acoustic parameters. 20 full-term normal human newborns (aged 1 to 4 days) had their cries recorded during routine blood withdrawal (pain context) 30 min. before a scheduled feeding (hunger context) and when subjected to kinetic stimuli during neurological examination (manipulation context). Type of cries, melodic contours, F0 parameters, but not the “macro” trend of the start of the fundamental frequency, indicated a difference in pain cries in the other two contexts. All the acoustic features considered showed an individual specificity. The peak frequencies of voiceless or partially voiced wails had the interesting property of being optimised as long distance signals. We hypothesised that this feature of infants' cries may have evolved in a time window when the infants were left in collective nurseries and not carried on the mothers' backs as maintained by the traditional view.

This paper focuses on the interaction between raising, subject–verb inversion and agreement in Modern Hebrew. It identifies, alongside ‘standard’ (i.e., English-like) subject-to-subject raising, two additional patterns where the embedded subject appears post-verbally. In one, the raising predicate exhibits long-distance agreement with the embedded subject, while in the other, a colloquial variant, it is marked with impersonal (3sm) agreement. The choice between the three raising constructions in the language is shown to be solely dependent on properties of the embedded clause. The data are discussed and analyzed against a background of typological and theoretical work on raising. The analysis, cast in the framework of Head-driven Phrase Structure Grammar (HPSG), builds on research on raising, selectional locality, agreement, subjecthood and information structure, as well as verb-initial constructions in Modern Hebrew.

We examined evolutionary relationships, hybridisation and genetic diversity in species of Dacrydium (Podocarpaceae) in Remote Oceania, where it is restricted to New Caledonia and Fiji. We used cpDNA sequence (trnL–trnF) data to construct a phylogeny and estimate taxon divergence by using a relaxed molecular clock approach. The phylogeny was verified using allozymes, which were also used to investigate genetic diversity of all species and the hybridisation dynamics of two endangered species, D. guillauminii and D. nidulum. Our results suggested that Dacrydium species in Remote Oceania form a monophyletic group that arose and diversified within the last 20 million years through long-distance dispersal and a range of speciation mechanisms. Whereas we detected no hybridisation between the Fijian species D. nausoriense and D. nidulum, we confirmed hybridisation between D. guillauminii and D. araucarioides in New Caledonia and determined introgression to be assymetric from the widespread D. araucarioides into the rare, restricted-range species D. guillauminii. In addition, D. guillauminii had lower genetic diversity than did the other species of Dacrydium studied, which had genetic diversity similar to that of other gymnosperms. Our results provided evidence for the recent and complex diversification of Dacrydium in Remote Oceania. In addition, low genetic diversity of and introgression from D. araucarioides, are of grave concern for the conservation of D. guillauminii.

This paper explores the implications of 'gradient dissimilation' (Jatteau & Hejná 2016) for the diachronic implementation of long-distance dissimilation (e.g. ChVCh > CVCh). Since dissimilation is usually considered as lexically sporadic, cases where it applies regularly throughout the lexicon should result from lexical diffusion. Against this assumption, we explore the hypothesis that gradient dissimilation may represent the phonetic precursor of completed, regular dissimilatory processes. Such cases might then be reanalysed as Neogrammarian types of change. To assess this question, we gather and analyse new data from Halh Mongolian, a language reported to show gradient dissimilation of the aspiration feature, and compare it to two completed patterns of aspiration dissimilation reconstructed within the Mongolic family: Chahar Mongolian and Monguor. The results suggest that the gradient dissimilation in Halh may represent the phonetic precursor of Chahar, but also that gradient dissimilation may be bidirectional for some speakers. An interesting difference between our Halh Mongolian results and the other patterns of the Mongolic family resides in the behaviour of /s/, which in our data does not pattern as expected with the aspirated stops.

Darwinian evolution tends to produce energy-efficient outcomes. On the other hand, energy limits computation, be it neural and probabilistic or digital and logical. Taking a particular energy-efficient viewpoint, we define neural computation and make use of an energy-constrained, computational function. This function can be optimized over a variable that is proportional to the number of synapses per neuron. This function also implies a specific distinction between ATP-consuming processes, especially computation per se vs the communication processes including action potentials and transmitter release. Thus to apply this mathematical function requires an energy audit with a partitioning of energy consumption that differs from earlier work. The audit points out that, rather than the oft-quoted 20 watts of glucose available to the brain (1, 2), the fraction partitioned to cortical computation is only 0.1 watts of ATP. On the other hand at 3.5 watts, long-distance communication costs are 35-fold greater. Other novel quantifications include (i) a finding that the biological vs ideal values of neural computational efficiency differ by a factor of 108 and (ii) two predictions of N, the number of synaptic transmissions needed to fire a neuron (2500 vs 2000).Significance StatementEngineers hold up the human brain as a low energy form of computation. However from the simplest physical viewpoint, a neuron’s computation cost is remarkably larger than the best possible bits/J – off by a factor of 108. Here we explicate, in the context of energy consumption, a definition of neural computation that is optimal given explicit constraints. The plausibility of this definition as Nature’s perspective is supported by an energy-audit of the human brain. The audit itself requires certain novel perspectives and calculations revealing that communication costs are 35-fold computational costs.

A new algorithm for multi-object recognition and localization is introduced in this paper. This algorithm deals with objects which have different reflectivity factors and distinguish color with respect to the other objects. Two beacons scan multi-color objects using long distance IR sensors to estimate their absolute locations. These two beacon nodes are placed at two corners of the environment. The recognition of these objects is estimated by matching the locations of each object with respect to the two beacons. A look-up table contains the distances information about different color objects is used to convert the reading of the long distance IR sensor from voltage to distance units. The locations of invisible objects are computed by using absolute locations of invisible objects method. The performance of introduced algorithm is tested with several experimental scenarios that implemented on color objects.

Abstract: In 1992 the agency responsible for regulating Canadian Telecommunications, the CRTC (Canadian Radio-television and Telecommunications Commission), authorized Unitel Communications Inc. to provide a public long-distance telephone service. For the first time Bell Canada, and six of the other telephone companies that comprise the Stentor common carrier consortium, would face competition in the market for public telephony (CRTC, 1992a). This article is critical of the CRTC decision. It analyzes the content and to a lesser extent the process that led to the CRTC decision in order to demonstrate: (1) that in order to justify its decision the Commission was obliged to ignore the initial objectives it had set for the proceedings; (2) that the ultimate ruling was based on a bogus problematic which by definition the monopoly common carriers could not respond to; (3) that the decision to liberalize was based on a selective and inconsistent use of economic theory; and (4) the decision was not grounded in a rational consideration of the evidence presented before the Commission, but rather it was the culmination of a piecemeal shift in policy in favour of competition that had begun in the early 1980s. Résumé: En 1992, l'agence responsable de la réglementation des télécommunications canadiennes, le CRTC (Le Conseil de la radiodiffusion et des télécommunications canadiennes), a autorisé Unitel Communications Inc. à offrir un service interurbain public (CRTC, 1992a). Pour la première fois, Bell Canada et les six autres compagnies téléphoniques membres du groupe Stentor devront faire face à un marché interurbain compétitif. Dans cet article, nous analysons la décision du CRTC, d'une perspective critique. On examine le contenu de la décision et à moindre degré le processus décisionnel qui a abouti à cette décision. Nous effectuons cette analyse dans le but: (1) de démontrer comment, pour justifier sa décision, le Conseil a été obligé d'abandonner en cours de route les objectifs initiaux qu'il s'était donnés; (2) de démontrer que la décision a été fondée sur une fausse problématique qui ne donnait presque aucune chance à Bell et aux autres membres de Stentor de défendre l'option du monopole; (3) de démontrer comment la décision d'ouvrir le marché interurbain à la compétition a été fondée sur une utilisation sélective et parfois contradictoire de la théorie économique; et (4) de démontrer jusqu'à quel point la décision n'a pas été fondée sur une évaluation équilibrée et rationnelle des arguments et témoignages présentés devant le Conseil; elle a été l'aboutissement d'un virage politique déjà commencé depuis le début des années 1980, virage qui a été effectué par morceaux (pièce à pièce) et qui n'a jamais été assujetti à une évaluation compréhensive et globale.

Propertius’ elegy 3.17 is full of references to Tibullus’ elegies, partly for reasons of convergence of context, partly because of the Propertian choice, to resume an earlier long-distance polemic with the other Roman elegiac poet.
