description: Στην παρούσα εργασία εξετάζονται οι δυνατότητες  των σύγχρονων λογισμικών σχεδίασης (CAD) στον σχεδιασμό χωρικών δικτυωμάτων δοκών. Τα συστήματα CAD βοηθούν στη δημιουργία, στην τροποποίηση, στην ανάλυση ή στη βελτιστοποίηση ενός σχεδιασμού και χρησιμοποιούνται από τον σχεδιαστή για να αυξήσει την παραγωγικότητα, να βελτιώσει την ποιότητα του σχεδιασμού, καθώς και να δημιουργήσει βάσεις δεδομένων για κάθε κατασκευή. Για την επιδίωξη των παραπάνω στόχων χρησιμοποιείται το λογισμικό Inventor της Autodesk.
Στην αρχή γίνεται μια εισαγωγική αναφορά στο σίδηρο και στις κατασκευαστικές δυνατότητες που παρείχε κατά τα αρχαία χρόνια. Τη θέση του σιδήρου θα λάβει ο χάλυβας, ένα υλικό που έφτασε να είναι πρωταγωνιστής στην εξέλιξη των μεταλλικών κατασκευών. Ύστερα από μια σύντομη περίληψη της ραγδαίας ανάπτυξης των μεταλλικών κατασκευών, παρουσιάζονται συνοπτικά μερικά από τα σημαντικότερα χαλύβδινα κτήρια που κατασκευάστηκαν, ενώ ταυτόχρονα γίνεται λόγος για τα πλεονεκτήματα αλλά και τα αρνητικά στοιχεία που παρατηρούνται στις κατασκευές αυτές.
Στο τμήμα του οδηγού χρήσης του λογισμικού Inventor, στο οποίο μελετάται λεπτομερώς το περιβάλλον του Frame Generator, γίνεται εκτενής παρουσίαση των αντίστοιχων εντολών, επεξηγούνται διεξοδικά τα βήματα που χρειάζεται να ακολουθήσει ο χρήστης για την σωστή εφαρμογή της κάθε εντολής και παρέχονται σχετικά παραδείγματα στο τέλος κάθε κεφαλαίου για περαιτέρω κατανόηση.
Επιπλέον, διαμορφώνεται συνδυαστική κατασκευή από την εκτέλεση όσο το δυνατόν περισσότερων εντολών. Η  κατασκευή προσομοιάζει το σκελετό ενός υπαρκτού μεταλλικού κτηρίου. Στόχος είναι να συνειδητοποιήσει ο χρήστης το εύρος των δυνατοτήτων του εν λόγω προγράμματος της Autodesk και να κατανοήσει τη λειτουργία του λογισμικού στο πλαίσιο των χωρικών δικτυωμάτων των δοκών.
Τέλος, προβάλλονται πίνακες στους οποίους διακρίνονται αναλυτικά τα τεχνικά χαρακτηριστικά, ράβδων, δοκών και κοίλων διατομών σύμφωνα με τον Ελληνικό Οργανισμό Τυποποίησης ΕΛ.Ο.Τ.

description: A new class of regular quaternionic functions, defined by power series in a natural fashion, has been introduced in recent years. Several results of the theory recall the classical complex analysis, whereas other results reflect the peculiarity of the quaternionic structure. A more recent paper identified a larger class of domains, on which the study of regular functions is most natural and not limited to the study of quaternionic power series. In the present paper we extend some basic results concerning the algebraic and topological properties of the zero set to regular functions defined on these domains. We then use these results to prove the Maximum and Minimum Modulus Principles and a version of the Open Mapping Theorem in this new setting.

Eccentric ellipsoidal variables (EEVs, "heartbeat stars") and their tidally excited oscillations (TEOs)
Creators: name: Kołaczek-Szymański, Piotr
Publisher: name: Zenodo
Year: 2024

description: Evolutionary tracks of the majority of binary and multiple systems fundamentally depend on tidal phenomena. Many common astrophysical problems, such as population synthesis or the statistical analysis of compact binary systems that are sources of gravitational waves, are based largely on the assumption that we can model various tidal effects. Among them, there is a unique type of stellar oscillations, so-called tidally excited oscillations (TEOs), which have many different properties compared to self-excited pulsations as they are resonantly driven by periodically varying tidal potential from the companion. These dynamical tides in eccentric binary systems can exchange energy and angular momentum with their orbital counterparts; hence, TEOs directly influence the evolution of the binary system. Despite several theoretical and detailed studies dedicated to TEOs, our knowledge about their actual efficiency is still limited and rather poorly constrained by observational data. Thanks to space-borne photometric surveys such as BRITE and TESS, we can approach providing an answer to this question.

description: A qubit (a spin-1/2 particle) prepared in the up state is scattered by local spin-flipping potentials produced by the two target qubits (two fixed spins), both prepared in the down state, to generate an entangled state in the latter when the former is found in the down state after scattering. The scattering process is analyzed in three dimensions, both to lowest order and in full order in perturbation, with an appropriate renormalization for the latter. The entanglement is evaluated in terms of the concurrence as a function of the incident and scattering angles, the size of the incident wave packet, and the detector resolution, to clarify the key elements for obtaining an entanglement with high quality. The characteristics of the results are also discussed in the context of (in)distinguishability of alternative paths for a quantum particle.

Money as a transaction technology : a game-theoretic approach
Creators: name: Wiens, Elmer G.
Publisher: name: University of British Columbia
Year: 2010

description: A barter economy and a monetary economy are modelled using the cooperative game approach. The feature that distinguishes the two economies is the manner in which exchange activities are organized in the face of transaction costs. While division of labour or specialization is exploited in the monetary economy's technology of exchange, it is not exploited in that of the barter economy. The presence of a medium of exchange in the monetary economy permits its specialized traders to operate efficiently. The cooperative game approach admits group rationality along with the usual assumption of individual rationality. Group rationality means that individuals are able to perceive their interdependence. Money is explained as the product of interactions between individual rationality (utility maximizing consumers and profit maximizing traders) and group rationality (the ability to perceive the benefits of monetary exchange versus barter exchange). Consequently, money is viewed not as an object, but as an institution. Its value reflects the relative superiority of a monetary economy over a barter economy.

description: We developed means to produce wafer scale, high-quality graphene films as large as 3 inch wafer size on Ni and Cu films under ambient-pressure and transfer them onto arbitrary substrates through instantaneous etching of metal layers. We also demonstrated the applications of the large-area graphene films for the batch fabrication of field-effect transistor (FET) arrays and stretchable strain gauges showing extraordinary performances. Transistors showed the hole and electron mobilities of the device of 1,100 cm2/Vs and 550 cm2/Vs at drain bias of -0.75V, respectively. The piezo-resistance gauge factor of strain sensor was ~6.1. These methods represent a significant step toward the realization of graphene devices in wafer scale as well as application in optoelectronics, flexible and stretchable electronics.

description: We study the statistical behavior of entanglement in quantum bipartite systems over fermionic Gaussian states as measured by von Neumann entropy and entanglement capacity. The focus is on the variance of von Neumann entropy and the mean entanglement capacity that belong to the so-defined second-order statistics. The main results are the exact yet explicit formulas of the two considered second-order statistics for fixed subsystem dimension differences. We also conjecture the exact variance of von Neumann entropy valid for arbitrary subsystem dimensions. Based on the obtained results, we analytically study the numerically observed phenomena of Gaussianity of von Neumann entropy and linear growth of average capacity.

We will also look from a group-theoretc point of view at the more general problem of expressing a function on a manifold in terms of its integrals over certain submanifolds. Finally, the extension of the tomographic maps to the quantum case is considered, as a Weyl-Wigner quantization of the classical case.

description: A 20-band sp3d5s* spin-orbit-coupled, semi-empirical, atomistic tight-binding model is used with a semi-classical, ballistic, field-effect-transistor (FET) model, to examine the ON-current variations to size variations of [110] oriented PMOS nanowire devices. Infinitely long, uniform, rectangular nanowires of side dimensions from 3nm to 12nm are examined and significantly different behavior in width vs. height variations are identified and explained. Design regions are identified, which show minor ON-current variations to significant width variations that might occur due to lack of line width control. Regions which show large ON-current variations to small height variations are also identified. The considerations of the full band model here show that ON-current doubling can be observed in the ON-state at the onset of volume inversion to surface inversion transport caused by structural side size variations. Strain engineering can smooth out or tune such sensitivities to size variations. The cause of variations described is the structural quantization behavior of the nanowires, which provide an additional variation mechanism to any other ON-current variations such as surface roughness, phonon scattering etc.

description: We analyse how market competition in a vertically differentiated polluting industry is affected by product variants that comply at different levels with "green" social norms. A green consumption behaviour is considered as a byword of good citizenship. Consumer preferences depend on a combination of hedonic quality and compliance with the norms. Assuming that the high hedonic quality variant complies less with the norms than the low hedonic quality one, we characterize the different equilibrium configurations, depending on the perceived intensity of such norms. Then, we focus on the role that institutions may have in using these norms to reduce pollution emissions.

description: We investigate the model dependence of no-helicity flip generalized parton distribution of the pion upon different approaches for the quark-hadron and quark-photon vertexes, in the spacelike region. In order to obtain information on contributions from both the valence and non-valence regions, we compare results for spacelike momentum transfers obtained from i) an analytic covariant model with a bare quark-photon vertex, ii) a Light-front approach with a quark-photon vertex dressed through a microscopic vector-meson model and iii) a Light-front approach based on the Relativistic Hamiltonian Dynamics. Our comparisons lead to infer the same dynamical mechanism, the one-gluon-exchange dominance at short distances, as a source of both the electromagnetic form factor at large momentum transfer and the parton distribution close to the end-points. The expected collinear behavior of the generalized parton distributions at high momentum transfer, i.e. a maximum for $x\sim 1$, is also illustrated, independently of the different approaches. Finally a comparison with recent Lattice calculations of the gravitational form factors is presented.

description: An algorithm is developed for efficiently constructing the Lorentz covariant effective three-point vertices of the decay of a particle into two daughter particles in which all the masses and spins of the three particles can be arbitrary. The closely-related one-to-one correspondence between the helicity formalism and the covariant formulation is exploited for counting the number of independent terms and identifying the basic covariant three-point vertices. Assembling the basic operators according to the developed algorithm enables us to construct all the covariant three-point vertices systematically.

description: Beam loading is the phenomenon which limits the charge and the beam quality in plasma based accelerators. An experimental study conducted with a laser-plasma accelerator is presented. Beam loading manifests itself through the decrease of the beam energy, the reduction of dark current and the increase of the energy spread for large beam charge. 3D PIC simulations are compared to the experimental results and confirm the effects of beam loading. It is found that, in our experimental conditions, the trapped electron beams generate decelerating fields on the order of 1 GV/m/pC and that beam loading effects are optimized for trapped charges of about 20 pC.

description: This paper presents two simulation models to explore the energy production potential of thorium-based nuclear fuels. The first model involves a basic simulation where thorium is converted into uranium-233 with limited energy efficiency, and the energy produced is evaluated. In the second study, an advanced reactor design is simulated, targeting maximum efficiency. The results of both scenarios are compared, and the energy amounts are evaluated in relation to the electricity needs of all households in Turkey. The study concludes that advanced simulations significantly enhance energy production by fully utilizing thorium's potential.

description: Study of the polarization behaviour in blazars is a powerful tool to discern the role of magnetic field in the variable emission process in their relativistic jets. We present here results of our systematic investigation on the correlation between optical flux and polarization variations for eight flat-spectrum radio quasars on various timescales using data from the Steward Observatory that covers a period of $\sim$10 years. On long time scales ($\sim$several months), from a total of 79 observing cycles, in 34 observing cycles, we found a significant positive correlation between optical flux and optical polarization degree (PD), negative correlation in 3 cycles and no correlation in 42 cycles. On short time scales ($\sim$few days), in 47 out of a total of 55 epochs, we found a positive correlation between optical flux and PD, while, on the remaining 8 epochs, an anti-correlation was detected between the two quantities. Moreover, we noticed a significant positive correlation between optical and $γ-$ray fluxes on 14 epochs and a negative correlation between the two on one epoch. While the observed optical flux changes well fit in the shock-in-jet model, the observed changes in PD are not explainable by changes in the power-law spectral index of the relativistic electrons in the jet. Instead, the observed varied correlations between optical flux and PD could be due to multi-zone emission regions or the enhanced flux coinciding with the emergence of a new emission knot with its magnetic field either aligned or misaligned with the large scale magnetic field.

description: The Kuiper belt object Orcus and its satellite Vanth form an unusual system in the Kuiper belt. Orcus is amongst the largest objects known in the Kuiper belt, but the relative size of Vanth is much larger than that of the tiny satellites of the other large objects. From Hubble Space Telescope observations we find that Orcus and Vanth have different visible colors and that Vanth does not share the water ice absorption feature seen in the infrared spectrum of Orcus. We also find that Vanth has a nearly face-on circular orbit with a period of 9.5393 +-0.0001 days and semimajor axis of 8980+-20 km, implying a system mass of 6.32+- 0.01 X 10^20 kg or 3.8% the mass of dwarf planet Eris. From Spitzer Space Telescope observations we find that the thermal emission is consistent with a single body with diameter 940+-70 km and a geometric albedo of 0.28+-0.04. Assuming equal densities and albedos, this measurements implies sizes of Orcus and Vanth of 900 and 280 km, respectively, and a mass ratio of 33. Assuming a factor of 2 lower albedo for the non-icy Vanth, however, implies sizes of 820 and 640 km and a mass ratio of 2. The measured density depends on the assumed albedo ratio of the two objects but is approximately 1.5+-0.3 g cm^-3$, midway between typical densities measured for larger and for smaller objects. The orbit and mass ratio is consistent with formation from a giant impact and subsequent outward tidal evolution and even consistent with the system having now achieved a double synchronous state. The system can equally well be explained, however, by initial eccentric capture, Kozai cycling which increases the eccentricity and decreases the pericenter of the orbit of Vanth, and subsequent tidal evolution inward.

Episodic activities of supermassive black holes at redshift $z\le 2$: driven by mergers?

description: It has been suggested for quite a long time that galaxy mergers trigger activities of supermassive black holes (SMBHs) on the grounds of imaging observations of individual galaxies. To quantitatively examine this hypothesis, we calculate quasar luminosity functions (LFs) by manipulating the observed galaxy LFs ($z\lesssim 2$) and theoretical merger rates from semi-analytical formulations. We find that the model reproduces the observed quasar LFs provided that the mass ratio ($q$) of the secondary galaxy to the newly formed one changes with cosmic time. The results show that the fraction of major mergers decreases from $f_{\rm maj}\sim 0.2$ at $z\sim 2$ to $f_{\rm maj}\to 0$ at $z\sim 0$. As a consequence, the newly formed SMBHs from major mergers at $z\sim 2$ may acquire a maximal spin due to the orbital angular momentum of the merging holes. Subsequently, random accretion led by minor mergers rapidly drives the SMBHs to spin down. Such an evolutionary trend of the SMBH spins is consistent with that radiative efficiency of accreting SMBHs strongly declines with cosmic time, reported by Wang et al. (2009). This suggests that minor mergers are important in triggering activities of SMBHs at low redshift while major mergers may dominate at high redshift.

Non-disjunction in aging female mice
Creators: name: Martin, Renée Halo
Publisher: name: University of British Columbia
Year: 2010

description: Classical studies have shown that reproductive performance declines with maternal age in humans and other mammals. There is an increase of trisomic offspring with maternal age in humans and an increase of trisomic embryos and fetuses with maternal age in mice. It has been suggested that this increase in non-disjunction is due to the decrease in chiasma frequency arid increase in univalents observed in the oocytes of old mice. This study was undertaken to determine the effects of maternal age on non-disjunction in the oocytes of CBA mice. Oocytes from CBA mice varying in age from two to eleven months were cultured to the metaphase II stage of meiosis and the chromosomes were analysed. The oocytes from three maternal age groups were compared with respect to the mean number of oocytes obtained per mouse, the frequency of maturation to metaphase II, and the frequency of numerical chromosome abnormalities. Both the mean number of oocytes obtained per mouse and the frequency of maturation decreased markedly with maternal age. The frequency of chromosome abnormalities in the oocytes increased with maternal age from the young to the middle aged mice but dropped off in the oldest maternal age group. No hyper-ploid (n+1) oocytes were observed in the young or old group of mice but 4.9% hyperploidy occurred in the middle age group. It is suggested that the lack of hyperploid oocytes in the old CBA females might be due to a threshold effect in which oocytes which are damaged by the number or type of univalents become atretic and do not progress to metaphase II. The frequency of diploid (2n) oocytes was 1.7% and was not maternal age dependent. An overall theory of maternal age related nondisjunction is proposed in which the various environmental and genetic factors known to affect non-disjunction are linked to an underlying mechanism of univalent production in oocytes.

description: Diese Dissertation beschäftigt sich mit dem kardiovaskulären und psychischen Gesundheitsstatus von Schulleitungen und Lehrkräften. Zu klären war, ob sich der Gesundheitsstatus von Schulleitungen und Lehrkräften unterscheidet, welche gesundheitlichen Gefährdungen in beiden Berufsgruppen bestehen, und ob damit ein Beitrag zur bisher defizitär untersuchten Schulleitergesundheit geleistet werden kann. Aus den Ergebnissen sollten Schlussfolgerungen für die Prävention der beiden Pädagogengruppen abgeleitet werden.

description: In this paper we investigate warm electron injection in a double gate SONOS memory by means of 2D full-band Monte Carlo simulations of the Boltzmann Transport Equation (BTE). Electrons are accelerated in the channel by a drain-to-source voltage VDS smaller than 3 V, so that programming occurs via electrons tunneling through a potential barrier whose height has been effectively reduced by the accumulated kinetic energy. Particle energy distribution at the semiconductor/oxide interface is studied for different bias conditions and different positions along the channel. The gate current is calculated with a continuum-based post-processing method as a function of the particle distribution obtained from Monte Carlo. Simulation results show that the gate current increases by several orders of magnitude with increasing drain bias and warm electron injection can be an interesting option for programming when short channel effects prohibit the application of larger drain bias.

description: In recent years, engineering of Light, Oxygen and Voltage (LOV) domains have resulted in the development of flavin based fluorescent proteins (FbFP). The improved FbFP iLOV is a flavin mononucleotide (FMN) dependent fluorescent protein with great promise as a smaller and potentially more stable oxygen-independent alternative to the well-stablished Green Fluorescent Protein (GFP). Particularly, within industrial biotechnology the properties of the FbFPs can be advantageous for in vivo bioprocess optimisation. In this project, iLOV and two closely related FbFPs, LOVC426A and phiLOV2.1, have been studied. These demonstrate different fluorescent properties, and it has been hypothesised that this relates to differences in protein dynamics. This is best studied by nuclear magnetic resonance (NMR). Preparation of iLOV for this purpose revealed unreported self-association tendencies of the protein, resulting in broadening of the resonances and low-quality spectra. The zwitterionic detergent CHAPS was found to disrupt the self-association, resulting in high quality spectra and allowing for near complete backbone resonance assignment of the three AtLOV2 derived FbFPs. The dimerisation propensity of the three FbFPs was further explored by gel filtration analysis, revealing that iLOV appear to populate three states: a monomeric form, a stable dimer, and an intermediate, less stable presumed dimeric species. Using X-filtered NMR, the interaction between iLOV and CHAPS was probed to identify a series of hydrophobic residues across the main β-sheet. Point mutations at these sites yielded several novel iLOV variants with reduced self-association without loss of fluorescence. The most promising candidate, iLOV5xβ, was further characterised, and compared with iLOV, phiLOV2.1 and LOVC426A. The utility of iLOV as a transcriptional reporter in E. coli was investigated using constitutive and inducible promoters. Expression of iLOV appeared to slow E. coli growth primarily in the lag phase of growth, with this effect being less severe when the novel variant iLOV5xβ was expressed. To develop an iLOV-based in vivo biosensor for the anaerobic production of succinate in E. coli, the native response system DcuS/R was utilised to design three types of biosensors. Finally, iLOV was used as a fluorescent reporter for production of the antimicrobial peptide (AMP) epidermicin NI01. This enabled screening of transformants for jackpot clones by both direct screening and FACS. The iLOV-tag both improved expression of the target and eased the development of purification protocols. A P. pastoris strain with yields suitable for commercial production of the AMP was identified by these methods.

description: Pyrochlore oxides are fascinating systems where strong, multi-orbital correlations in concert with geometrical frustration give rise to unanticipated physical properties. The detailed mechanism of the insulator-metal transitions (IMT) underpinning these phenomena is, however, ill-understood in general. Motivated thereby, we study the IMT in the pyrochlore ${\rm Hg_{2}Ru_{2}O_{7}}$ using LDA+DMFT. In contrast to the well-known examples of Mott transitions in TMO, we show that, in the negative charge-transfer situation characteristic of \hg, self-doping plays a crucial role in the emergence of an orbital-selective IMT. We argue that this mechanism has broader relevance to other correlated pyrochlore oxides.

description: Runaway stars ejected from the Galactic disk populate the halo of the Milky Way. To predict the spatial and kinematic properties of runaways, we inject stars into a Galactic potential, compute their trajectories through the Galaxy, and derive simulated catalogs for comparison with observations. Runaways have a flattened spatial distribution, with higher velocity stars at Galactic latitudes less than 30 degrees. Due to their shorter stellar lifetimes, massive runaway stars are more concentrated towards the disk than low mass runaways. Bound (unbound) runaways that reach the halo probably originate from distances of 6--12 kpc (10--15 kpc) from the Galactic center, close to the estimated origin of the unbound runaway star HD 271791. Because runaways are brighter and have smaller velocities than hypervelocity stars (HVSs), radial velocity surveys are unlikely to confuse runaway stars with HVSs. We estimate that at most 1 runaway star contaminates the current sample. We place an upper limit of 2% on the fraction of A-type main sequence stars ejected as runaways.

description: Der Beitrag flacher Küstengewässer als lokale Quellen oder Senken für atmosphärische Treibhausgase (THG) ist ungenau. In dieser Dissertation wurden zwei Messplattformen mit Sensoren im Flachwasser der Ostsee (< 6 m) eingesetzt, um biogeochemische Variablen und THG in hoher zeitlicher Auflösung zu erfassen. Außerdem wurde eine Wiederbefeuchtung eines küstennahen Moorgebietes untersucht, wobei die Auswirkungen einer Vernässung mit Brackwasser auf die THG-Emissionen weitgehend unbekannt sind, obwohl ein positiver Effekt auf die Verringerung der CH4 Emissionen erwartet wird.

description: There is a large and important collection of Ramsey-type combinatorial problems, closely related to central problems in complexity theory, that can be formulated in terms of the asymptotic growth of the size of the maximum independent sets in powers of a fixed small (directed or undirected) hypergraph, also called the Shannon capacity. An important instance of this is the corner problem studied in the context of multiparty communication complexity in the Number On the Forehead (NOF) model. Versions of this problem and the NOF connection have seen much interest (and progress) in recent works of Linial, Pitassi and Shraibman (ITCS 2019) and Linial and Shraibman (CCC 2021). We introduce and study a general algebraic method for lower bounding the Shannon capacity of directed hypergraphs via combinatorial degenerations, a combinatorial kind of "approximation" of subgraphs that originates from the study of matrix multiplication in algebraic complexity theory (and which play an important role there) but which we use in a novel way. Using the combinatorial degeneration method, we make progress on the corner problem by explicitly constructing a corner-free subset in $F_2^n \times F_2^n$ of size $Ω(3.39^n/poly(n))$, which improves the previous lower bound $Ω(2.82^n)$ of Linial, Pitassi and Shraibman (ITCS 2019) and which gets us closer to the best upper bound $4^{n - o(n)}$. Our new construction of corner-free sets implies an improved NOF protocol for the Eval problem. In the Eval problem over a group $G$, three players need to determine whether their inputs $x_1, x_2, x_3 \in G$ sum to zero. We find that the NOF communication complexity of the Eval problem over $F_2^n$ is at most $0.24n + O(\log n)$, which improves the previous upper bound $0.5n + O(\log n)$.

description: We use the Millennium simulation to probe the correlation between cluster velocities and their shapes and the consequences for measurements of the kinetic Sunyaev-Zeldovich (kSZ) effect. Halos are generally prolate ellipsoids with orientations that are correlated with those of nearby halos. We measure the mean streaming velocities of halos along the lines that separate them, demonstrating that the peculiar velocities and the long axes of halos tend to be somewhat aligned, especially for the most massive halos. Since the kSZ effect is proportional to the line-of-sight velocity and the optical depth of the cluster, the alignment results in a strong enhancement of the kSZ signature in clusters moving along the line of sight. This effect has not been taken into account in many analyses of kSZ signatures.
