description: The succeeding pages contain scores of my music—Passage to Kublb, Dalamhati ni Osang, Pintig, and Talibun-ag. "Passage to kublb" , for large orchestra, is a travelogue. Using a certain number of intervals, the instruments go through a journey, signifying life's constant changes and ceaseless motion. Melodic and rhythmic motives are used, fragmentation, and variation of timbral colors. "Kublb" is a fictional place; in essence, a destination of one's life journey. "Dalamhati ni Osang" (Lament of Osang) for a soprano, bass clarinet and marimba, is a composition revolving around a hextatonic scale which goes through a process of change as the music progresses. The text, written in the Filipino language, conveys the lament of a woman wanting to escape from her sorrows as she pleads her beloved to "lull" her; thus the repeated phrase "iduyan mo, o hirang" which means lull me or cradle me, my beloved. The woman's concept of "sleep" is an end-goal from which she frees herself of bitter memories of the past. The nuances of the vocal lines point to some native materials common to the Filipino "kundiman"(ballad). Use of expressive lines in legato phrasing, repeated sections (ABA form), and in some instances, use of embellishments like the repeated grace notes. The hextatonic scale is the composer's own material injected to some pre-formed structure already existing as in the mentioned ballad. "Pintig" (Pulses of Mother Earth) which was originally written for the "Elektra Women's Choir" during a pre-Christmas choral reading is a study of tribal vocables and different vocal effects. Stomping of foot, tapping, and other ritual sounds are employed to concoct an amalgam of primitive or earthy vista. (Note that the recording provided with this thesis is simply a reading session of the piece). "Talibun-ag " is a coined title from the Filipino words "tali" and "bun-ag" (bondage and birth) which if combined literally can mean "birth of freedom". This is a music drama for a chamber ensemble (piano, alto flute and percussions), a mono-dramatist and a choral quartet.

description: Multi-electron semiconductor quantum dots have found wide application in qubits, where they enable readout and enhance polarizability. However, coherent control in such dots has typically been restricted to only the lowest two levels, and such control in the strongly interacting regime has not been realized. Here we report quantum control of eight different resonances in a silicon-based quantum dot. We use qubit readout to perform spectroscopy, revealing a dense set of energy levels with characteristic spacing far smaller than the single-particle energy. By comparing with full configuration interaction calculations, we argue that the dense set of levels arises from Wigner-molecule physics.

description: An interesting consequence of the modern cosmological paradigm is the spatial infinity of the universe. When coupled with naturalistic understanding of the origin of life and intelligence, which follows the basic tenets of astrobiology, and with some fairly incontroversial assumptions in the theory of observation selection effects, this infinity leads, as Ken Olum has recently shown, to a paradoxical conclusion. Olum's paradox is related, to the famous Fermi's paradox in astrobiology and SETI studies. We, hereby, present an evolutionary argument countering the apparent inconsistency, and show how, in the framework of a simplified model, deeper picture of the coupling between histories of intelligent/technological civilizations and astrophysical evolution of the Galaxy, can be achieved. This strategy has consequences of importance for both astrobiological studies and philosophy.

description: Das LHCb Experiment am Large Hadron Collier am CERN wird momentan für die nächste Datennahme verändert und modernisiert. Die instantane Luminosität wird um einen Faktor fünf erhöht, damit mehr Daten in kürzerer Zeit aufgenommen werden können. Die erste Stufe der Datennahme, der Hardwaretrigger, wird entfernt. LHCb muss nun eine Kollisionsrate von 30MHz in Echtzeit verarbeiten. In dieser Arbeit werden drei Projekte vorgestellt,die signifikant zu der Entwicklung eines schnellen und effizienten Triggersystems beitragen. Der erste Beitrag ist ein Scheduling Algorithmus mit vernachlässigbarem Overhead in der neuen Trigger-Applikation. Der Algorithmus steuert das Multi-Threading des Systems und ist der erste Algorithmus in LHCb, der den technischen Spezifikationen des Systems genügt. Durch die Restriktion auf Inter-Event Parallelismus können die meisten teuren Entscheidungen schon vor der Laufzeit der Applikation getroffen werden. Der zweite Beitrag besteht aus mehreren Algorithmen zur Filterung und Kombination von Teilchen in der Kollision. Diese Algorithmen sind bis zu mehreren Größenordnungen schneller als die aktuellen, etablierten Algorithmen. Der Einsatz der neuen Algorithmen in der zweiten Trigger-Phase (HLT2) ist ein wichtiger Schritt zur Vervollständigung eines Trigger-Systems, dass den erhöhten Anforderungen entspricht. Das letzte Projekt beschäftigt sich mit der Bandbreite, mit der der Trigger Kollisionen abspeichert. Dazu wird die wichtigste Selektion im HLT2 betrachtet, der topologische Trigger. Dieser Trigger versucht, Zerfälle von beauty Hadronen inklusiv zu selektieren. Zuerst wird der Selektionsalgorithmus selber optimiert. In einem zweiten Schritt werden die Kollisionen, die der Selektion entsprechen, getrimmt. Irrelevante Information für die Analyse von beauty Hadronen in diesen Kollisionen werden entfernt. Damit kann die Bandbreite pro gespeicherter Kollision verringert werden.

description: Durante la fase di iniezione in Adone devono essere generati dei segnali di sincronismo fra la radiofrequenza (RF) acceleratrice, il cannone del LINAC ed i kickers di iniezione in modo da poter selezionare il numero (da uno a diciotto) e la posizione dei bunches da iniettare. Inoltre per i sistemi di feedback longitudinali e trasversali devono essere generati dei segnali di trigger sincroni con i segnali dei bunches. Il sistema di timing attualmente utilizzato permette di operare con tre bunches al massimo e non puo' essere gestito via computer. Inoltre poiche' il sistema e' implementato in tre moduli standard NIM il funzionamento complessivo puo' essere influenzato da fattori quali ad es. le interconnessioni fra i moduli e la stabilita' delle tensioni di alimentazioni (piu' racks in sala controllo sono serviti da un unico alimentatore con conseguenti problemi di cadute di tensione e disturbi in funzione sia del tipo di carico che della corrente assorbita). Per superare le limitazioni di cui sopra parte del circuito e' stata riprogettata in modo da funzionare autonomamente dal punto di vista delle alimentazioni (alimentazione da rete), e di iniettare fino a diciotto bunches con controllo remoto (via GPIB).

description: Due to the covid19 crisis, public transport (PT) systems are facing new challenges. Regarding restrictive measures such as physical distancing and the successive returning of passengers after the intelligent lockdown, significant lack of transport capacity can be expected. In this paper, the transport capacity of a PT network is assessed, using a mathematical passenger route choice and train scheduling model. By analysing the overall number of transported passengers and the resulting link and train utilization; the networks capabilities of facilitating different demands under capacity restrictions (e.g. physical distancing) are addressed. The analysis is performed on the Dutch railway network. The results show that at most 50% of the pre-covid19 demand can be transported, while most of the trains will be highly utilized reaching their maximum occupation. Thus, significantly more parts of the network are becoming highly utilized, leading to a more congested and vulnerable system than in normal conditions before covid19.

Regular spiking in high conductance states: the essential role of inhibition

description: Strong inhibitory input to neurons, which occurs in balanced states of neural networks, increases synaptic current fluctuations. This has led to the assumption that inhibition contributes to the high spike-firing irregularity observed in vivo. We used single compartment neuronal models with time-correlated (due to synaptic filtering) and state-dependent (due to reversal potentials) input to demonstrate that inhibitory input acts to decrease membrane potential fluctuations, a result that cannot be achieved with simplified neural input models. To clarify the effects on spike-firing regularity, we used models with different spike-firing adaptation mechanisms and observed that the addition of inhibition increased firing regularity in models with dynamic firing thresholds and decreased firing regularity if spike-firing adaptation was implemented through ionic currents or not at all. This novel fluctuation-stabilization mechanism provides a new perspective on the importance of strong inhibitory inputs observed in balanced states of neural networks and highlights the key roles of biologically plausible inputs and specific adaptation mechanisms in neuronal modeling.

description: Tungsten trioxide adopts a variety of structures which can be intercalated with charged species to alter the electronic properties, thus forming `tungsten bronzes'. Similar optical effects are observed upon removing oxygen from WO_3, although the electronic properties are slightly different. Here we present a computational study of cubic and hexagonal alkali bronzes and examine the effects on cell size and band structure as the size of the intercalated ion is increased. With the exception of hydrogen (which is predicted to be unstable as an intercalate), the behaviour of the bronzes are relatively consistent. NaWO_3 is the most stable of the cubic systems, although in the hexagonal system the larger ions are more stable. The band structures are identical, with the intercalated atom donating its single electron to the tungsten 5d valence band. Next, this was extended to a study of fractional doping in the Na_xWO_3 system (0 < x < 1). A linear variation in cell parameter, and a systematic change in the position of the Fermi level up into the valence band was observed with increasing x. In the underdoped WO_3-x system however, the Fermi level undergoes a sudden jump into the conduction band at around x = 0.2. Lastly, three compounds of a layered WO_4×a,wdiaminoalkane hybrid series were studied and found to be insulating, with features in the band structure similar to those of the parent WO_3 compound which relate well to experimental UV-visible spectroscopy results.

description: HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-processed material at high speeds inside the old hydrogen-rich PN. In this letter we present GTC MEGARA integral field spectroscopic observations of the innermost regions of HuBi 1 at high spectral resolution $\simeq16$ km s$^{-1}$ and multi-epoch sub-arcsec images obtained $\simeq 12$ yr apart. The analysis of these data indicates that the inner regions of HuBi 1 were ejected $\simeq200$ yr ago and expand at velocities $\simeq300$ km s$^{-1}$, in excellent agreement with the born-again scenario. The unprecedented tomographic capabilities of the GTC MEGARA high-dispersion observations used here reveal that the ejecta in HuBi 1 has a shell-like structure, in contrast to the disrupted disk and jet morphology of the ejecta in other born-again PNe.

The remaining fermionic constraints are all second class, which we treat by the Dirac bracket. Upon quantization, all of the transverse coordinates are inevitably non-commutative.

description: The explosive molecular outflow detected decades ago in the Orion BN/KL region of massive star formation was considered to be a bizarre event. This belief was strengthened by the non detection of similar cases over the years with the only exception of the marginal case of DR21. Here, we confim a similar explosive outflow associated with the UCH$_{\rm II}$ region G5.89$-$0.39 that indicates that this phenomenon is not unique to Orion or DR21. Sensitive and high angular resolution ($\sim$ 0.1$''$) ALMA CO(2$-$1) and SiO(5$-$4) observations show that the molecular outflow in the massive star forming region G5.89$-$0.39 is indeed an explosive outflow with an age of about 1000 yrs and a liberated kinetic energy of 10$^{46-49}$ erg. Our new CO(2$-$1) ALMA observations revealed over 30 molecular filaments, with Hubble-like expansion motions, pointing to the center of UCH$_{\rm II}$ region. In addition, the SiO(5$-$4) observations reveal warmer and strong shocks very close to the origin of the explosion, confirming the true nature of the flow. A simple estimation for the occurrence of these explosive events during the formation of the massive stars indicates an event rate of once every $\sim$100 yrs, which is close to the supernovae rate.

description: We perform first principles simulations for the structural, elastic and electronic properties of orthorhombic samarium orthoferrite $SmFeO_3$ within the framework of density functional theory. A number of different density functionals, such as local density approximation, generalized gradient approximation, Hubbard interaction modified functional, modified Becke$-$Johnson approximation and Heyd$-$Scuseria$-$Ernzerhof hybrid functional have been used to model the exact electron exchange-correlation. We estimate the energy of the ground state for different magnetic configurations of $SmFeO_3$. The crystal structure of $SmFeO_3$ is characterized in terms of the lattice parameters, atomic positions, relevant ionic radii, bond lengths and bond angles. The stability of the $SmFeO_3$ orthorhombic structure is simulated in terms of its elastic properties. For the electronic structure simulations, we provide estimates based on density functionals with varying degrees of computational complexities in the Jacob's ladder.

description: In this paper, we first derive an intrinsic definition of classical triple intersection numbers of K_S, where S is a complex toric surface, and use this to compute the extended Picard-Fuchs system of K_S of our previous paper, without making use of the instanton expansion. We then extend this formalism to local fourfolds K_X, where X is a complex 3-fold. As a result, we are able to fix the prepotential of local Calabi-Yau threefolds K_S up to polynomial terms of degree 2. We then outline methods of extending the procedure to non canonical bundle cases.

description: We compare the yields of two methods to obtain Bernstein type pointwise estimates for the derivative of a multivariate polynomial in points of some domain, where the polynomial is assumed to have sup norm at most 1. One method, due to Sarantopoulos, relies on inscribing ellipses into the convex domain K. The other, pluripotential theoretic approach, mainly due to Baran, works for even more general sets, and yields estimates through the use of the pluricomplex Green function (the Zaharjuta -Siciak extremal function). Using the inscribed ellipse method on non-symmetric convex domains, a key role was played by the generalized Minkowski functional a(K,x). With the aid of this functional, our current knowledge is precise within a constant (squareroot 2) factor. Recently L. Milev and the author derived the exact yield of this method in the case of the simplex, and a number of numerical improvements were obtained compared to the general estimates known. Here we compare the yields of this real, geometric method and the results of the complex, pluripotential theoretical approaches on the case of the simplex. In conclusion we can observe a few remarkable facts, comment on the existing conjectures, and formulate a number of new hypothesis.
title: Surface X-ray Diffraction Studies of Electrode/Vacuum and Electrode/Electrolyte Interfaces

Publisher: name: University of Liverpool Repository
Year: 2018

description: This thesis presents in situ Surface X-ray Diffraction (SXRD) studies of surfaces and interfaces, in both Ultra High Vacuum (UHV) and an electrochemical environment. Primarily Crystal Truncation Rod (CTR) measurements are utilised to determine a model for the atomic structure at the interface. A SXRD characterisation of the clean Ag(110) and Ag(111) surfaces in UHV were determined as a reference for the rest of the work in this thesis. Following this the growth conditions and structures of a silicene layer on Ag(111) were investigated, by Low Energy Electron Diffraction (LEED) and preliminary SXRD study of the interface structure is presented. A comprehensive study of the Ag(hkl)/alkaline interface is presented. X-ray Voltammetry (XRV) measurements have been performed to determine the potential dependence of the system. CTR measurements have been used to determine the structure at both the electrode and electrolyte sides of the interface. The results reveal large structural changes on the electrolyte side of the interface, with the response of relaxation of the surface layers in the metal. The presence of specifically adsorbed OH on the surface stabilises cations in a compact double layer through non-covalent interactions. The studies were extended to determine the effects of saturating the electrolyte gases, CO and O2 on the double layer structure. The results indicate that double layer structure is subtly perturbed, and hints at a change in the nature of bonding at the interface. Time resolved SXRD measurements are utilised to determine the dynamics of the restructuring of the electrolyte layering at the Ag(111)/Alkaline interface. In order to gain a comprehensive picture of the structural dynamics, two other systems are studied; the Au(111) reconstruction to determine the timescale of the (1 x 1) ↔ (p ×√3) reconstruction, and the underpotential deposition of Ag on Au(111). The results indicate that the mass transport of ions through electrolyte is on a timescale comparable to the charge transfer, whereas the ordering of ions and surface metal atoms occurs on much longer timescales.
title: Turkey’s Kin State Policy in the Balkans: The Muslim Community from Dobruja

description: This article is focused on empirical research of Turkey’s kin state policy in
the Muslim community in Dobruja post 1990. It investigates how Turkey
has managed to accumulate influence and soft power potential by using its
mother-state position to strengthen the community of Muslim Turks and
Tatars in Dobruja. The study explains the factors in the community which
determined the manifestation of Islamic fundamentalist actors in this
period, and the context in which Turkey stepped in and countered them
through its own actors. The main goal of the study is to identify the areas
in which the Turkish state acted, through cultural and religious funds and
through development assistance. It profiles the Turkish state actors in each
of these areas. The study is an overview of the presence, purposes and
activities of these actors at the local level, while also providing an
evaluation of the impact their action strategies have in the local Muslim
community.

description: Η σχέση ανάμεσα στα Συστήματα Μεταφορών και Χρήσεων Γης υπήρξε διαχρονικά ένα ενδιαφέρον ζήτημα για έρευνα. Οι σχέσεις του δίπολου χρήσεις γης - μεταφορές δεν αποτελούν μόνο τους σημαντικούς εκείνους παράγοντες για να κατανοήσει κανείς τη φύση και την εξέλιξη της αστικής μορφής, αλλά παρουσιάζουν και ενδιαφέρον στη διαδικασία λήψης αποφάσεων. Η αδιάκοπη ανατροφοδότηση της αλληλεξάρτησής τους, ορίζει άλλοτε την ισορροπία και άλλοτε την ανισορροπία των κοινωνικο-οικονομικών παραμέτρων μιας περιοχής. Είναι, λοιπόν, σημαντική η ολοκληρωμένη θεώρηση και αντιμετώπιση του Πολεοδομικού και Κυκλοφοριακού Σχεδιασμού, με σκοπό την ανάπτυξη μιας περιοχής.
description: The relationship between transport and land use systemw has been diachronically an interesting research subject. Land use - transportation relationships are not only key factors to understanding the nature and evolution of urban form, but also have important policy implications. The constant feedback of their interaction, defines the equilibrium or not of the socio-economical parameters of an area. This explains the importance of an integrated consideration and confrontation of Urban and Transportation Planning, aiming to the evolution of an area.

description: Context: New eclipse minimum timings of the M4.5/M4.5 binary CM Dra were obtained between the years 2000 and 2007. In combination with published timings going back to 1977, a clear non-linearity in observed-minus-calculated (O-C) times has become apparent. Several models are applied to explain the observed timing behavior. Aims: Revealing the processes that cause the observed O-C behavior, and testing the evidence for a third body around the CM Dra system. Methods: The O-C times of the system were fitted against several functions, representing different physical origins of the timing variations. Results: An analysis using model-selection statistics gives about equal weight to a parabolic and to a sinusoidal fitting function. Attraction from a third body, either at large distance in a quasi-constant constellation across the years of observations or from a body on a shorter orbit generating periodicities in O-C times is the most likely source of the observed O-C times. The white dwarf GJ 630.1B, a proper motion companion of CM Dra, can however be rejected as the responsible third body. Also, no further evidence of the short-periodic planet candidate described by Deeg et al. (2000) is found, whereas other mechanisms, such as period changes from stellar winds or Applegate's mechanism can be rejected. Conclusions: A third body, being either a few-Jupiter-mass object with a period of 18.5+-4.5 years or an object in the mass range of 1.5M_jup to 0.1M_sun with periods of hundreds to thousands of years is the most likely origin of the observed minimum timing behavior.

description: The article describes the application of the Hough transform to a honeycomb block image. The problem of cutting a mold from a honeycomb block is described. A number of image transformations are considered to increase the efficiency of the Hough algorithm. A method for obtaining a binary image using a simple threshold, a method for obtaining a binary image using Otsu binarization, and the Canny Edge Detection algorithm are considered. The method of binary skeleton (skeletonization) is considered, in which the skeleton is obtained using 2 main morphological operations: Dilation and Erosion. As a result of a number of experiments, the optimal sequence of processing the original image was revealed, which allows obtaining the coordinates of the maximum number of faces. This result allows one to choose the optimal places for cutting a honeycomb block, which will improve the quality of the resulting shapes.

description: Morphologic and morphometric data of a lion-like cat skull found in the Zandobbio (Lombardy -Italy) Eemian ossiferous rubble and stored in the Civic Museum of Natural History "E. Caffi" of Bergamo are presented.  The skull shows the typical lion morphology and its relatively small dimensions suggest that it belonged to a female individual. Carnassial tooth analysis underlines advanced lion characters already recognized in Italy during the Eemian. According to skull and teeth characters it is possible to ascribe the specimen to the group of Upper Pleistocene lion-like cats Panthera leo spelaea (Goldfuss, 1810).  The presence of P. leo spelaea in the Quaternary deposit of Zandobbio has remarkable importance not only locally. In fact, besides being the first report of this great feline at Zandobbio, it is the second report from Lombardy and, the oldest certain P. leo spelaea finding and the oldest complete P. leo spelaea  skull known from Italy to date. The advanced P. leo spelaea characters were already present in Italy during the Eemian.

Social drama in an activity-based peer group: a theatre for fostering self- and other- understanding
Creators: name: Novak, Helen Joanne
Publisher: name: University of British Columbia
Year: 2009

description: . A phenomenological approach was used to investigate the social experiences of "at-risk" adolescents as they occurred in the context of a drama project comprised of discussion and role play based on social issues deemed relevant by the participants. Experiences of self- and other-understanding were examined in and beyond the context of the project. Fourteen adolescents enrolled in an alternate "transition" classroom program for adolescents identified as "at risk" for school, drop out participated in the social issues drama project during 12 class periods over one month. The researcher and her assistant facilitated the activities in the project. Initially, participants completed questionnaires assessing demographic background, stress, and empathy. The adolescents' responses served as a springboard to the qualitative data. Over the next eight class periods in the project, the group engaged in discussion and dramatic role play activities based on relevant social issues identified by the participants. All of the above activities were audio taped. During the last two sessions, the adolescents participated in individual interviews that were audio taped about their experiences in the project. Transcripts of the discussions, role plays, and interviews were analyzed concurrently with observations and field notes taken by the researcher and assistant. The data were organized into four components: (1) a description of the adolescents' background; (2) a content analysis of the social issues identified for the subject matter of the drama activities, namely relationship issues in peer, family, and friendship contexts; (3) analysis of the participants' processes of perspective-taking, empathy, and prosocial behavior in and beyond the context of the role play activities; and (4) the adolescents' experiences of the project and the effects they perceived as resulting from the project. Implications for educational practice and for further research are discussed.
title: The Political Dimension of Ante Marković's Reform Project. “We must develop democracy and a Third Yugoslavia.”
Creators: name: Sasso, Alfredo
Publisher: name: Universität Graz
Year: 2020

description: This article focuses on the political dimension of Ante Marković’s attempt
to reform the federation of Yugoslavia during his mandate as prime
minister between 1989 and 1991. While the literature about the crisis and
dissolution of Yugoslavia has usually depicted Marković as the initiator of
crucial reforms in the economic domain but having limited action outside of
those measures, here the attention is devoted to his agency in the political
domain, namely: 1) the attempt to redesign the institutional framework to
restore the fundaments of Yugoslav statehood, 2) the introduction of a statewide
multiparty system that would recreate a supra-national demos, and 3)
the reanimation of the historical and symbolic principles of democratic
Yugoslavism. These initiatives brought the federal government and the
political party led by Marković to overt conflict with substate republican
leaderships and with nationalist forces.

Walter Scotts orientalisierte Jüdin Rebecca: Negativexempel oder Symbolfigur der englischen Weiblichkeit zu Beginn des 19. Jahrhunderts?

description: Sir Walter Scott gilt als Erfinder des historischen Romans. Sein 1819 veröffentlichtes Werk ‚Ivanhoe‘ ist zeitlich im Mittelalter angesiedelt und bedient unter anderem beständige Klischees um das Rittertum, die Kreuzzüge und Robin Hood. Auch antisemitische Stereotype sind mit dem Geldverleiher Isaac von York und seiner Tochter präsent. Dabei fällt die schöne Rebecca aufgrund ihrer Darstellung abseits der typischen Vorurteile nicht nur anderen Figuren innerhalb der Erzählung positiv auf. Zeitgenössische Stimmen loben sie überschwänglich und empören sich darüber, dass der Held Ivanhoe letztlich die kühle Rowena ehelicht, statt seinen Gefühlen für Rebecca nachzugeben. Gegenwärtige Problematiken zur Diskussion in eine ferne Vergangenheit zu verlegen, ist in der Literatur eine häufig angewandte Strategie. Auch Scott nutzt das Mittelalter als Projektionsfläche für seinerzeit relevante Diskurse. Aber welche Rolle spielt dabei die schöne Jüdin? Und inwiefern ist ihre Inszenierung auch in der weiteren Rezeptionsgeschichte von Scotts Werk relevant

description: The bivalve Daonella Mojsisovics, 1874 is very common in the Middle Triassic pelagic facies, whereas the record of this genus from shallow water limestones is rare. In the present paper a new species of Daonella, named D. pseudograbensis, is described from the Esino Limestone, a Ladinian (Middle Triassic) carbonate platform in the central Southern Alps. The species is described from Brembana Valley, where the Esino Limestone is rather rich in bioclastic lenses yielding faunas with bivalves, cephalopods, gastropods, brachiopods, corals and calcareous algae. Daonella pseudograbensis n. sp. is based on very well preserved specimens, which are often articulated and closed, all coming from the same locality. The new species shows a narrow range of intraspecific and ontogenetic morphologic variations. It is easy distinguishable from the other species of the genus for the outline and ornamentation; it therefore differs from D. grabensis Kittl, 1912, the most similar species, for the longer anterior dorsal margin.Pdf

description: The development of automatic perception systems and techniques for bio-inspired flapping-wing robots is severely hampered by the high technical complexity of these platforms and the installation of onboard sensors and electronics. Besides, flapping-wing robot perception suffers from high vibration levels and abrupt movements during flight, which cause motion blur and strong changes in lighting conditions. This paper presents a perception dataset for bird-scale flapping-wing robots as a tool to help alleviate the aforementioned problems. The presented data include measurements from onboard sensors widely used in aerial robotics and suitable to deal with the perception challenges of flapping-wing robots, such as an event camera, a conventional camera, and two Inertial Measurement Units (IMUs), as well as ground truth measurements from a laser tracker or a motion capture system. A total of 21 datasets of different types of flights were collected in three different scenarios (one indoor and two outdoor). To the best of the authors' knowledge this is the first dataset for flapping-wing robot perception.
