description: We study resonant pair production of heavy particles in fully hadronic final states by means of jet substructure techniques. We propose a new resonance tagging strategy that smoothly interpolates between the highly boosted and fully resolved regimes, leading to uniform signal efficiencies and background rejection rates across a broad range of masses. Our method makes it possible to efficiently replace independent experimental searches, based on different final state topologies, with a single common analysis. As a case study, we apply our technique to pair production of Higgs bosons decaying into $b\bar{b}$ pairs in generic New Physics scenarios. We adopt as benchmark models radion and massive KK graviton production in warped extra dimensions. We find that despite the overwhelming QCD background, the $4b$ final state has enough sensitivity to provide a complementary handle in searches for enhanced Higgs pair production at the LHC.

title: The benefits of biodiversity: Human-wildlife interactions in urban Guyana
Creators: name: Fisher, Jessica C.
Publisher: name: University of Kent
Year: 2020

description: Worldwide, human populations are growing, the climate is changing, and natural habitat is being converted to alternative land-uses. In particular, urbanisation has both positive and negative implications for society and biodiversity conservation. Within cities, there is increasing evidence that green (e.g. parks, gardens) and blue spaces (e.g. rivers, coast) can benefit human subjective wellbeing by restoring attentional fatigue and reducing stress, while also providing resources to support biodiversity. However, it remains unclear how biodiversity, and other specific features of urban green and blue spaces, enhance or detract from wellbeing. These details are crucial to informing land-use management and policy decisions in towns and cities. Much of the existing evidence originates from the global North, despite biodiversity loss, population growth, and urbanisation rates accelerating in the global South. Drawing on theories and methods from multiple disciplines, this thesis empirically explores relationships between green and blue spaces and human wellbeing in Georgetown, the capital city of Guyana. This biodiversity-rich country in northern South America has the highest rate of suicide worldwide and is poised to transform due to the discovery of vast quantities of off-shore oil. First, I expose a dose-response relationship between patterns of visitor use to urban green and blue spaces and experiential wellbeing, finding that age, safety concerns, and nature-relatedness dictate patterns of use. Second, I show that green and coastal blue spaces are important for bird diversity and human wellbeing respectively, although the two do not relate. Third, I assess how human perceptions of bird diversity, naturalness, sounds, and safety affect wellbeing, influenced by how restorative these spaces are perceived to be. Finally, I use participatory video to triangulate earlier findings, discovering that biodiversity provides a multisensory experience, with place attachment, personal insecurity, and cultural beliefs contributing to wellbeing in green and coastal blue space. This interdisciplinary thesis makes important empirical contributions to the field of biodiversity-wellbeing research, representing the first evidence gathered from neotropical South America. Overall, my results provide a valuable evidence-base to inform the development of interventions (e.g. targeted public health and educational campaigns) in biodiversity-rich cities like Georgetown. From a wider perspective, these findings could be harnessed by policy-makers striving to meet international targets on sustainability while maximising human quality of life at a national scale.

description: The exact ground state of the reduced BCS Hamiltonian is investigated numerically for large system sizes and compared with the BCS ansatz. A "canonical'' order parameter is found to be equal to the largest eigenvalue of Yang's reduced density matrix in the thermodynamic limit. Moreover, the limiting values of the exact analysis agree with those obtained for the BCS ground state. Exact results for the ground state energy, level occupations and a pseudospin-pseudospin correlation function are also found to converge to the BCS values already for relatively small system sizes. However, discrepancies persist for a pair-pair correlation function, for inter-level correlations of occupancies and for the fidelity susceptibility, even for large system sizes where these quantities have visibly converged to well-defined limits. Our results indicate that there exist non-perturbative corrections to the BCS predictions in the thermodynamic limit.

description: Sulfonated poly (vinylidene fluoride-co-hexafluoropropylene) (SPVdF-HFP)/sulfonated graphene oxide (SGO) hybrid membrane was prepared via solution casting process. Incorporation of SGO nanosheets into SPVdF-HFP matrix increases the density of sulfonic acid moieties of hybrid membrane. This offer better water uptake, good proton conductivity, than pristine SPVdF-HFP membrane. Additionally, the complex structure generated between SGO and membrane chains helps to reduce methanol uptake and swelling ratio of the hybrid membrane. The formation of electrostatic interaction between membrane backbone and SGO skeleton helps the SPVdF-HFP/SGO to retained lower weight loss than SPVdF-HFP during TGA analysis. The presence of SGO nanosheets in membrane matrix is confirmed by morphological studies. The SPVdF-HFP/SGO membrane achieved maximum proton conductivity of 7.8 mS/cm at 70 °C and low methanol permeability of 2.567 × 10−7 cm2/s at 70 °C whereas the pristine SPVdF-HFP membrane exhibits 1.7 mS/cm and 3.105 × 10−7 cm2/s. From the obtained good results of hybrid membrane, we believe that the SPVdF-HFP/SGO would be a promising candidate for the application of DMFCs.

description: Encoding information in quantum systems can offer surprising advantages but at the same time there are limitations that arise from the fact that measuring an observable may disturb the state of the quantum system. In our work, we provide an in-depth analysis of a simple question: What happens when we perform two measurements sequentially on the same quantum system? This question touches upon some fundamental properties of quantum mechanics, namely the uncertainty principle and the complementarity of quantum measurements. Our results have interesting consequences, for example they can provide a simple proof of the optimal quantum strategy in the famous Clauser-Horne-Shimony-Holt game. Moreover, we show that the way information is encoded in quantum systems can provide a different perspective in understanding other fundamental aspects of quantum information, like non-locality and quantum cryptography. We prove some strong equivalences between these notions and provide a number of applications in all areas.

description: Object detection in remote sensing images relies on a large amount of labeled data for training. However, the increasing number of new categories and class imbalance make exhaustive annotation impractical. Few-shot object detection (FSOD) addresses this issue by leveraging meta-learning on seen base classes and fine-tuning on novel classes with limited labeled samples. Nonetheless, the substantial scale and orientation variations of objects in remote sensing images pose significant challenges to existing few-shot object detection methods. To overcome these challenges, we propose integrating a feature pyramid network and utilizing prototype features to enhance query features, thereby improving existing FSOD methods. We refer to this modified FSOD approach as a Strong Baseline, which has demonstrated significant performance improvements compared to the original baselines. Furthermore, we tackle the issue of spatial misalignment caused by orientation variations between the query and support images by introducing a Transformation-Invariant Network (TINet). TINet ensures geometric invariance and explicitly aligns the features of the query and support branches, resulting in additional performance gains while maintaining the same inference speed as the Strong Baseline. Extensive experiments on three widely used remote sensing object detection datasets, i.e., NWPU VHR-10.v2, DIOR, and HRRSD demonstrated the effectiveness of the proposed method.

description: Using the recently derived NNLO cross sections \cite{Czakon:2013goa}, we provide NNLO+NNLL theoretical predictions for top quark pair production based on all the available NNLO PDF sets, and compare them with the most precise LHC and Tevatron data. In this comparison we study in detail the PDF uncertainty and the scale, $m_t$ and $α_s$ dependence of the theoretical predictions for each PDF set. Next, we observe that top quark pair production provides a powerful direct constraint on the gluon PDF at large $x$, and include Tevatron and LHC top pair data consistently into a global NNLO PDF fit. We then explore the phenomenological consequences of the reduced gluon PDF uncertainties, by showing how they can improve predictions for Beyond the Standard Model processes at the LHC. Finally, we update to full NNLO+NNLL the theoretical predictions for the ratio of top quark cross sections between different LHC center of mass energies, as well as the cross sections for hypothetical heavy fourth-generation quark production at the LHC.

Generalized Riemann curvature corrections to type II supergravity
Creators: name: Garousi, Mohammad R.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We observe that the replacement of the Riemann curvature with the generalized Riemann curvature into the corrections to the type II supergravity at order $α'^3$ which are in terms of the contractions of four Riemann curvatures $R^4$, is not fully consistent with the S-matrix elements in the superstring theory. In particular, they produce non-zero S-matrix elements for odd number of B-field strengths which are not consistent with the string theory results. Using the consistency of the couplings with the linear T-duality as a guiding principle, we consider all T-duality invariant couplings and fix their coefficients by requiring them to be consistent with the S-matrix elements. The new Lagrangian density is then equivalent to the replacement of the generalized Riemann curvature into the expression $t_8t_8R^4$.

description: Both non-Abelian gauge fields and minimally interacting massless matter fields are localized on a domain wall in the five-dimensional spacetime. Field-dependent gauge coupling naturally gives a position-dependent coupling to localize non-Abelian gauge fields on the domain wall. An economical field content allows us to eliminate a moduli for a instability, and to demonstrate the positivity of the position-dependent coupling in the entire moduli space. Effective Lagrangian similar to the chiral Lagrangian is found with a new feature of different coupling strengths for adjoint and singlet matter that depend on the width of the domain wall.

description: CdS and Ag-doped CdS (Cd1-xAgxS, x = 0.02, 0.04 and 0.06) nanoparticles (NPs) with average Scherer’s sizes 9.9 nm, 9.6 nm, 10.5 nm and 12.8 nm, respectively, were successfully synthesized and systematically characterized using various experimental techniques. The catalytic activities of these NPs have been evaluated by an ultrasound assisted synthesis of fourteen 5(a-n) types of 1,8-dioxodecahydroacridine (DODHAs) derivatives via multi-component reaction (MCR) among dimedone (2 mmol), aryladehyde (1 mmol) and ammonium acetate (1 mmol) or aniline (1 mmol) or p-toluidine (1 mmol) in deionized water (DIW) at room temperature (RT) just in 15 min. Excellent yields and reusability of the catalyst up to six consecutive runs were remarkably obtained in each case; 89% being the highest yield for x = 0.06 compared to 20% yield of x = 0, indicating vividly the importance of Ag doping in CdS. Ag doping helps to increase the number of acidic sites enhancing the acidity as confirmed from NH3-TPD, zeta potential, conductivity and surface area of the catalysts. This methodology illustrates clearly a very facile procedure, with wide applicability, extending the scope to aliphatic and aromatic compounds as source for nitrogen in the synthesis of these acridines.

description: In this study, we analyzed the weak decays induced by $J^P = \frac{1}{2}^{+} \to \frac{3}{2}^{-} $ transitions within the light-cone sum rules. Specifically, semileptonic decays of the bottom baryons into the P-wave baryons $Λ_b \to Λ_c(2625) \ell ν_l$ and $Ξ_b \to Ξ_c(2815) \ell ν_l$ as well as nonleptonic $Λ_b \to Λ_c(2625) π(ρ)$ and $Ξ_b \to Ξ_c(2815) π(ρ)$ decays are investigated. The form factors for the considered transitions are obtained within the sum rules method. With the calculated form factors, the decay widths of the processes are determined. Up to now, only the decay width for $Λ_b^0 \to Λ_c^+ μ^- ν_μ$ has been measured among the considered decays, and we observe that our finding is quite compatible with the measurement. We also compare our results with the predictions of other approaches.

description: The extragalactic X-ray binary IC 10 X-1 has attracted attention as it is possibly the host of the most massive stellar-mass black-hole (BH) known to date. Here we consider all available observational constraints and construct its evolutionary history up to the instant just before the formation of the BH. Our analysis accounts for the simplest possible history that includes three evolutionary phases: binary orbital dynamics at core collapse, common envelope (CE) evolution, and evolution of the BH--helium star binary progenitor of the observed system. We derive the complete set of constraints on the progenitor system at various evolutionary stages. Specifically: right before the core collapse event, we find the mass of the BH immediate progenitor to be > 31 Msun (at 95% of confidence, same hereafter). The magnitude of the natal kick imparted to the BH is constrained to be < 130 km/s. Furthermore, we find that the "enthalpy" formalism recently suggested by Ivanova & Chaichenets is able to explain the existence of IC 10 X-1 without the need of invoking unreasonably high CE efficiencies. With this physically motivated formalism, we find that the CE efficiency required to explain the system is in the range of 0.6--1.

description: No process in nature can perfectly clone an arbitrary quantum state. But is it possible to engineer processes that replicate quantum information with vanishingly small error? Here we demonstrate the possibility of probabilistic super-replication phenomena where N equally prepared quantum clocks are transformed into a much larger number of M nearly perfect replicas, with an error that rapidly vanishes whenever M is small compared to the square of N. The quadratic replication rate is the ultimate limit imposed by Quantum Mechanics to the proliferation of information and is fundamentally linked with the Heisenberg limit of quantum metrology.

description: Soliton rate equations are based on non-Kolmogorovian models of probability and naturally include autocatalytic processes. The formalism is not widely known but has great unexplored potential for applications to systems interacting with environments. Beginning with links of contextuality to non-Kolmogorovity we introduce the general formalism of soliton rate equations and work out explicit examples of subsystems interacting with environments. Of particular interest is the case of a soliton autocatalytic rate equation coupled to a linear conservative environment, a formal way of expressing seasonal changes. Depending on strength of the system-environment coupling we observe phenomena analogous to hibernation or even complete blocking of decay of a population.

description: We study the impact of a projectile onto a bed of 3 mm grains immersed in an index-matched fluid. Specifically, we vary the amount of prestrain on the sample, strengthening the force chains within the system. We find this affects only the prefactor of linear depth-dependent term in the stopping force. We therefore attribute this term to pressure within the material, and not the grain-intruder friction as is sometimes suggested. Using a laser sheet scanning technique to visualize internal grain motion, a high-speed camera, and particle tracking, we can measure the trajectory of each grain throughout an impact event. Microscopically, our results indicate that weaker initial force chains result in more irreversible, plastic rearrangements during impact, suggesting static friction between grains does play a substantial role in the energy dissipation within the granular material.

description: Big data, which is derived from humans or machines, starting with social media and extending to smartphones or sensors, in forms of texts, images or transactions, is a continuously evolving field.
Thus, the ongoing increase of data generated creates a need for knowledge extraction from it, through data analysis. Several areas are engaged in data mining, and in particular the area of machine learning which has been well established over the past years. Various techniques and methods of machine learning are trying to solve big data problems and these two areas consist
now an integral part. This particular combination is the main subject of this study, which aims to implement a large-scale text processing architecture. More specifically, this architecture focuses on processing streaming texts derived from Reddit in real-time and the classification thereof as sarcastic or non-sarcastic through a machine learning model. The architecture uses the latest
technologies in the field of information processing through distributed platforms such as Apache Kafka and Spark as well as state-of-the-art but also simple and powerful ML algorithms, i.e Random Forests, Naive Bayes and Logistic Regression. After comparing the methodology and design of each individual piece forming the final layout, a selection of the most appropriate model is made followed by the implementation of the framework. Success rates exported were quite close
to the relevant literature and sometimes higher, depending on each technique examined. Finally, results are indexed in the distributed search engine Elasticsearch and are evaluated through the Kibana plugin.

description: The influence of wax inhibitor molecular weight on wax crystallization was investigated in three steps: (1) Wax inhibitor fractionation via stepwise precipitation or ultrasonic disintegration, (2) characterization of inhibitor and sub-fractions in terms of molecular weight distribution, hydrodynamic radius, and precipitation from pure solvent, and (3) inhibitor effect on wax appearance temperature (WAT), waxy gelling, and wax crystal morphology. Stepwise precipitation yielded narrower molecular weight distributions, whereas ultrasonic disintegration reduced the average molecular weight and increase the polydispersity index. Changes in inhibitor molecular weight could improve as well as diminish WAT depression. Waxy gelation temperature showed similar trends, but overall effects were more pronounced. It was concluded the wax inhibitor molecular weight is a parameter that can be used to fine-tune additives to a particular waxy oil, but only after an effective PPD type has been identified.

description: We study the dynamics of a quantum $p$-spin glass model starting from initial states defined in microcanonical shells, in a classical regime. We compute different chaos estimators, such as the Lyapunov exponent and the Kolmogorov-Sinai entropy, and find a marked maximum as a function of the energy of the initial state. By studying the relaxation dynamics and the properties of the energy landscape we show that the maximal chaos emerges in correspondence with the fastest spin relaxation and the maximum complexity, thus suggesting a qualitative picture where chaos emerges as the trajectories are scattered over the exponentially many saddles of the underlying landscape. We also observe hints of ergodicity breaking at low energies, indicated by the correlation function and a maximum of the fidelity susceptibility.

description: Multifunctional thin films in energy-related devices often must be electrically insulating where a single nanoscale defect can result in complete device-scale failure. Locating and characterizing such defects presents a fundamental problem where high-resolution imaging methods are needed to find defects, but imaging with high spatial resolution limits the field of view and thus the measurement throughput. Here, we present a novel high-throughput method for detecting sub-micron defects in insulating thin films by leveraging the electrochemiluminescence (ECL) of luminol. Through a systematic study of reagent concentrations, buffers, voltage, and excitation time, we identify optimized conditions at which it is possible to detect features with areas ~500 times smaller than the area interrogated by a single pixel of the camera, showing high-throughput detection of sub-micron defects. In particular, we estimate the minimum detectable features to be lines as narrow as 2.5 nm in width and pinholes as small as 35 nm in radius. We further explore this method by using it to characterize a nominally insulating phenol film and find conductive defects that are cross-correlated with high-resolution atomic force microscopy to provide feedback to synthesis. Given the inherent parallelizability and scalability of this assay, it is expected to have a major impact on the automated discovery of multifunctional films.

description: We report new limits on spin-independent WIMP-nucleon interaction cross-section using 39.5 kg-days of data taken with a p-type point-contact germanium detector of 840 g fiducial mass at the Kuo-Sheng Reactor Neutrino Laboratory. Crucial to this study is the understanding of the selection procedures and, in particular, the bulk-surface events differentiation at the sub-keV range. The signal-retaining and background-rejecting efficiencies were measured with calibration gamma sources and a novel n-type point-contact germanium detector. Part of the parameter space in cross-section versus WIMP-mass implied by various experiments is probed and excluded.

Nodal band-off-diagonal superconductivity in twisted graphene superlattices

description: The superconducting state and mechanism are among the least understood phenomena in twisted graphene systems. For instance, recent tunneling experiments indicate a transition between nodal and gapped pairing with electron filling, which is not naturally understood within current theory. We demonstrate that the coexistence of superconductivity and flavor polarization leads to pairing channels that are guaranteed by symmetry to be entirely band-off-diagonal, with a variety of unusual consequences: most notably, the pairing invariant under all symmetries can have protected nodal lines or be fully gapped, depending on parameters, and the band-off-diagonal chiral d-wave state exhibits transitions between gapped and nodal regions upon varying the chemical potential. We demonstrate that nodal band-off-diagonal pairing can be the leading state when only phonons are considered, and is also uniquely favored by fluctuations of a time-reversal-symmetric intervalley-coherent order motivated by recent experiments. Consequently, band-off-diagonal superconductivity allows for the reconciliation of several key experimental observations in graphene moiré systems.

Picard-Vessiot theory of differentially simple rings

description: In Picard-Vessiot theory, the Galois theory for linear differential equations, the Picard-Vessiot ring plays an important role, since it is the Picard-Vessiot ring which is a torsor (principal homogeneous space) for the Galois group (scheme). Like fields are simple rings having only (0) and (1) as ideals, the Picard-Vessiot ring is a differentially simple ring, i.e. a differential ring having only (0) and (1) as differential ideals. Having in mind that the classical Galois theory is a theory of extensions of fields, i.e. of simple rings, it is quite natural to ask whether one can also set up a Picard-Vessiot theory where the base is not a differential field, but more general a differentially simple ring. It is the aim of this article to give a positive answer to this question, i.e. to set up such a differential Galois theory.

description: Mesoporous magnetite (Fe3O4) nanoparticles were synthesized via a simple process of Fe2+ and Fe3+ co-precipitating with OH− from different sources of chemical bases (NH4OH and NaOH) under ambient air. Two routes of an impregnation process were performed using deionized water or ethanol solvent with equal weight ratios of the synthesized Fe3O4 and activated carbon (AC). To reveal microstructures, surface characteristics, crystal structures, chemical functionalities and magnetization properties of the synthesized Fe3O4, AC and Fe3O4/AC composites, all of the synthesized powders were characterized using various techniques. As a model of heavy metals contaminated in wastewater effluent, hexavalent chromium (Cr(VI)) aqueous solutions were prepared in ranges of 30–50 mg/l for the adsorption experiment. Pure phase of Fe3O4 nanoparticles was formed in the synthesized route using NaOH based on characterized results. Goethite phase (α-FeOOH) mixed with the Fe3O4 phase was found in the synthesized route using NH4OH. AC and Fe3O4/AC composites showed higher efficiencies for Cr(VI) reduction in the solutions compared with the synthesized Fe3O4. Magnetic properties of the synthesized Fe3O4 and Fe3O4/AC composites could assist in separating the used absorbents out from the solutions. Adsorption mechanisms were finally discussed in terms of microstructural investigations and chemical analysis on composite surfaces.

description: Mathematical inequalities, combined with atomic-physics sum rules, enable one to derive lower and upper bounds for the Rosseland and/or Planck mean opacities. The resulting constraints must be satisfied, either for pure elements or mixtures. The intriguing law of anomalous numbers, also named Benford's law, is of great interest to detect errors in line-strength collections required for fine-structure calculations. Testing regularities may reveal hidden properties, such as the fractal nature of complex atomic spectra. The aforementioned constraints can also be useful to assess the reliability of experimental measurements. Finally, we recall that it is important to quantify the uncertainties due to interpolations in density-temperature opacity (or more generally atomic-data) tables, and that convergence studies are of course unavoidable in order to address the issue of completeness in terms of levels, configurations or superconfigurations, which is a cornerstone of opacity calculations.

description: Η βιομετρική ταυτοποίηση χρησιμοποιείται στην επιστήμη των υπολογιστών ως μια μορφή αναγνώρισης και ελέγχου πρόσβασης. Τα τελευταία χρόνια όλο και περισσότερα συστήματα χρησιμοποιούν έλεγχο πρόσβασης με βιομετρική ταυτοποίηση, γιατί εκτός από την ασφάλεια, προσφέρουν και ευκολία σε σχέση με τις παραδοσιακές μεθόδους.
Σκοπός της παρούσας διπλωματικής εργασίας είναι η σχεδίαση και υλοποίηση μιας ενσωματωμένης εφαρμογής αναγνώρισης ίριδας μέσω ενός Android smartphone. Η όλη υλοποίηση μπορεί να κατηγοριοποιηθεί σε τρία βασικά μέρη.
Αρχικά, έγινε μελέτη του φωτισμού, ώστε η φωτογραφία, που θα ληφθεί από το smartphone, να καλύπτει τις ελάχιστες προϋποθέσεις (ανάλυση, φωτεινότητα, χρωματική ισορροπία) και να μπορεί να εφαρμοστεί ο αλγόριθμος αναγνώρισης.
Στη συνέχεια, υλοποιήθηκε ο αλγόριθμος αναγνώρισης της ίριδας που περιλαμβάνει τον εντοπισμό των εικονοστοιχείων, που ανήκουν στην ίριδα. Μετά, πραγματοποιήθηκε η μετατροπή των καρτεσιανών συντεταγμένων των εικονοστοιχείων, που βρέθηκαν να ανήκουν στην ίριδα σε πολικές συντεταγμένες. Κατόπιν, εκτελέστηκε η κωδικοποίηση των εικονοστοιχείων της ίριδας. Συγκρίνοντας τελικά τους κωδικούς που αντιστοιχούν στις ίριδες, αποφασίστηκε η ταυτοποίηση του ατόμου.
Τέλος, αναπτύχθηκε μια εφαρμογή σε λειτουργικό Android, η οποία επιτρέπει στο χρήστη να φωτογραφίσει την ίριδα ενός ατόμου. Επιπλέον δίνεται η δυνατότητα να την συγκρίνει άμεσα με μια δεύτερη φωτογραφία, ελέγχοντας την ομοιότητα τους, βάσει του προηγούμενου αλγορίθμου.

description: Ο σκοπός αυτής της διπλωματικής ήταν να δημιουργηθεί ένας επεξεργαστής ARM με τη χρήση της γλώσσας προγραμματισμού Bluespec System Verilog(BSV). Η BSV έχει μία θεμελιωδώς διαφορετική προσέγγιση στη σχεδίαση υλικού, συγκριτικά με άλλες γλώσσες περιγραφής υλικού. Βασίζεται στη δημιουργία κυκλωμάτων  από ότι στην απλή περιγραφή κυκλωμάτων και επίσης βασίζεται σε ατομικούς κανόνες συναλλαγών αντί για μια συνολική σύγχρονη άποψη του κόσμου. O επεξεργαστής είναι μέλος της ARM7 οικογένειας επεξεργαστών, έχει 3 στάδια pipeline, χρησιμοποιεί 32-bit αρχιτεκτονική και βασίζεται στο ARMv4 σύνολο εντολών. Επιπλέον ο επεξεργαστής υποστηρίζει όλα τα διαφορετικά modes λειτουργίας. Τα mode λειτουργίας είναι User, Fast Interrupt(FIQ), Interrupt(IRQ), Supervisor, Abort, System και Undefined. Ο αριθμός των τύπων των διαφορετικών εντολών που υλοποιήθηκαν είναι 26. Ο καθένας από αυτούς τους διαφορετικούς τύπους έχει επιπλέον λειτουργίες ανάλογα της συνθήκη της εντολής και το τρόπο με τον οποίο έχει διευθυνσιοδότηθεί. Για την επιβεβαίωσης της σωστής λειτουργίας του επεξεργαστή χρησιμοποιήθηκε κώδικας assembly . Αυτός ο κώδικας παράχθηκε από  κώδικα C++ μέσω του ARM gcc
description: The goal of this thesis was to construct an ARM processor using the Bluspec System Verilog language(BSV). BSV has a fundamentally different approach to hardware design, comparing to other Hardware Description Languages. It is based on circuit generation rather than merely circuit description and is also based on atomic transactional rules instead of a globally synchronous view of the world. The processor belongs to the ARM7 family, it has a 3-stage pipeline, it uses a 32-bit architecture and is based on ARMv4 instruction set. In addition the processor supports all the operating modes. The modes of operation are User, Fast Interrupt(FIQ), Interrupt(IRQ), Supervisor, Abort, System and Undefined. The amount of different types of instructions that were implemented is 26. Each and every one of these types has additional functions depending on the condition codes and the addressing modes of the instruction. For the verification of the design, assembly code was used. This assembly code was produced by C++ code, through the ARM GCC.
