description: Στο πλαίσιο της παρούσας διπλωματικής εργασίας επιχειρήθηκε η έρευνα των βασικότερων κανόνων του ιδιωτικού δικαίου αναφορικά με τις συγκρούσεις συμφερόντων που προκύπτουν όταν ένα φυσικό ή νομικό πρόσωπο έχει επιφορτιστεί με την διεκπεραίωση ξένων υποθέσεων. Η έρευνα έγινε από τη σκοπιά των βασικότερων δικαιικών περιοχών στις οποίες εκδηλώνεται το φαινόμενο,δηλαδή στο πλαίσιο της άμεσης αντιπροσώπευσης (αρ. 211 επ. ΑΚ), στο πλαίσιο των προστατευτικών θεσμών του ΑΚ (γονική μέριμνα, επιτροπεία ανηλίκου, δικαστική συμπαράσταση, δικαστική επιμέλεια ξένων υποθέσεων), στο πλαίσιο των νομικών προσώπων και στο πλαίσιο ταγορών παροχής επενδυτικών υπηρεσιών. Σε κάθε μια από τις περιοχές αυτές εντοπίστηκαν και εξατάστηκαν οι μηχανισμοί που χρησιμοποιούνται από το νομοθέτη για αντιμετώπιση του φαινομένου της σύγκρουσης συμφερόντων. Στη συνέχεια, επιχειρήθηκε η σύγκριση των κανόνων και η κατηγοριοποίησή τους σε επιμέρους κατηγορίες.
description: In this Thesis was attempted the research of the most basic rules of private law in regard to the conflicts of interests, that arise when a natural or legal person has been charged with the transaction foreign affairs. The research became from the perspective of the main areas, in which is expressed the phenomenon, that is in the frame of direct representation, in the frame of protective instititions (parental concern, child guardianship, guardianship, judicial custody of foreign affairs), in the frame of legal persons and in the frame of investment services. In each of these areas were identified and were examinated the mechanisms that are used by the legislator for confrontation of phenomenon of conflict of interest. Afterwards was attempted the comparison of the rules and their classification into individual categories.

description: Recently two encryption schemes were proposed by combining circular bit shift and XOR operations, under the control of a pseudorandom bit sequence (PRBS) generated from a chaotic system. This paper studies the security of these two encryption schemes and reports the following findings: 1) there exist some security defects in both schemes; 2) the underlying chaotic PRBS can be reconstructed as an equivalent key by using only two chosen plaintexts; 3) most elements in the underlying chaotic PRBS can be obtained by a differential known-plaintext attack using only two known plaintexts. Experimental results are given to demonstrate the feasibility of the proposed attack.

Equivariant Chow groups and multiplicities
Creators: name: Nyenhuis, Michael
Publisher: name: University of British Columbia
Year: 2008

description: We propose a definition of equivariant Chow groups for schemes with a torus action and develop the intersection theory related to it. The equivariant intersection theories that have been considered in the past have been the Chow groups and the K-theory of the quotient scheme, as well as the equivariant K-groups of the original scheme. The equivariant Chow groups are related to all of these. At first glance, we would expect a strong relationship with the equivariant K-groups. As it turns out, the equivariant Chow groups are more closely related to the Chow groups of the quotient scheme. We chose to restrict to tori since for them the equivariant cycles are of a particularly nice form. For general groups the equivariant cycles are harder to describe, and so the intersection theory is far messier, if it even exists. By restricting to tori, we are able to define an equivariant multiplicity that behaves similarly to the degree in the projective case. In particular, we are able to show that for certain schemes, the equivariant multiplicity of an equivariant cycle in the equivariant Chow group is defined and is an invariant of that cycle. While much of this work involves generalizing the work of others, in particular the work of Fulton, Rossmann and Borho, Brylinski and Macpherson, our approach is new. The equivariant Chow groups have not been considered in the past and relating the equivariant multiplicities to the equivariant Chow groups is new as well.

description: A time-dependent current-density-functional theory for many-particle systems in interaction with arbitrary external baths is developed. We prove that, given the initial quantum state $|Ψ_0>$ and the particle-bath interaction operator, two external vector potentials ${\bf A}({\bf r},t)$ and ${\bf A}'({\bf r},t)$ that produce the same ensemble-averaged current density, $\bar{{\bf j}({\bf r},t)}$, must necessarily coincide up to a gauge transformation. This result greatly expands the applicability of time-dependent density-functional theory to open quantum systems, and allows for first-principles calculations of many-particle time evolution beyond Hamiltonian dynamics.

description: Recent experimental advances have made it possible to study excited structure in superheavy nuclei. The observed states have often been interpreted as quasi-particle excitations. We show that in superheavy nuclei collective vibrations systematically appear as low-energy excitation modes. By using the microscopic Triaxial Projected Shell Model, we make a detailed prediction on gamma-vibrational states and their E2 transition probabilities to the ground state band in Fermium and Nobelium isotopes where active structure research is going on, and in 270Ds, the heaviest isotope where decay data have been obtained for the ground-state and for an isomeric state.

Τα αποτελέσματα έδειξαν ότι για να γίνουν περισσότερο αποτελεσματικές οι γεωργικές εκμεταλλεύσεις θα πρέπει να μειώσουν τις εισροές τους κατά 15,4 – 37,6%, ενώ οι εκμεταλλεύσεις του 2013, είναι αυτές που παρουσιάζουν την υψηλότερη τεχνική αποτελεσματικότητα (ΤΕCRS = 0,846).
description: This study aims to analyze the technical efficiency of agricultural holdings in the prefecture of Pieria in Northern Greece with final goal the extraction of useful conclusions regarding the strategical directions of the farm managers. The analysis concerns farms that took part in the annual studies of the Farm Accountancy Data Network (FADN) in a three year period, from 2012 to 2014. The data needed, was collected using questionnaires that were addressed to farms cultivating mostly perennial crops. In order to estimate the technical efficiency of the agricultural holdings, the Data Envelopment Analysis (DEA) method was used. The dependent variable used was the number of sales and the independent variables were the main production factors (soil, labor and fixed and variable capital). The results showed that farms must reduce their inputs in a scale from 15.4% up to 37.6%, in order to become more efficient. Also the farms with the highest technical efficiency (TEcrs= 0,846), were the farms participating in the 2013 FADN annual study.

description: We present a variational Monte Carlo (VMC) study of spontaneous Fermi surface symmetry breaking in the t-J model. We find that the variational energy of a Gutzwiller projected Fermi sea is lowered by allowing for a finite asymmetry between the x- and the y-directions. However, the best variational state remains a pure superconducting state with d-wave symmetry, as long as the underlying lattice is isotropic. Our VMC results are in good overall agreement with slave boson mean field theory (SBMFT) and renormalized mean field theory (RMFT), although apparent discrepancies do show up in the half-filled limit, revealing some limitations of mean field theories. VMC and complementary RMFT calculations also confirm the SBMFT predictions that many-body interactions can enhance any anisotropy in the underlying crystal lattice. Thus, our results may be of consequence for the description of strongly correlated superconductors with an anisotropic lattice structure.

description: In this work we explore the possible existence of static, spherically symmetric and stationary, axisymmetric traversable wormholes coupled to nonlinear electrodynamics. Considering static and spherically symmetric (2+1) and (3+1)-dimensional wormhole spacetimes, we verify the presence of an event horizon and the non-violation of the null energy condition at the throat. For the former spacetime, the principle of finiteness is imposed, in order to obtain regular physical fields at the throat. Next, we analyze the (2+1)-dimensional stationary and axisymmetric wormhole, and also verify the presence of an event horizon, rendering the geometry non-traversable. Relatively to the (3+1)-dimensional stationary and axisymmetric wormhole geometry, we find that the field equations impose specific conditions that are incompatible with the properties of wormholes. Thus, we prove the non-existence of the general class of traversable wormhole solutions, outlined above, within the context of nonlinear electrodynamics.

description: We present the first study relating structural parameters of precipitate free Ge0.95Mn0.05 films to magnetisation data. Nanometer sized clusters - areas with increased Mn content on substitutional lattice sites compared to the host matrix - are detected in transmission electron microscopy (TEM) analysis. The films show no overall spontaneous magnetisation at all down to 2K. The TEM and magnetisation results are interpreted in terms of an assembly of superparamagnetic moments developing in the dense distribution of clusters. Each cluster individually turns ferromagnetic below an ordering temperature which depends on its volume and Mn content.

description: We calculate the transverse momentum and invariant mass dependence of elliptic flow of thermal dileptons for Au+Au collisions at the Relativistic Heavy Ion Collider. The system is described using hydrodynamics, with the assumption of formation of a thermalized quark-gluon plasma at some early time, followed by cooling through expansion, hadronization and decoupling. Dileptons are emitted throughout the expansion history: by annihilation of quarks and anti-quarks inthe early quark-gluon plasma stage and through a set of hadronic reactions during the late hadronic stage. The resulting differential elliptic flow exhibits a rich structure, with different dilepton mass windows providing access to different stages of the expansion history. Elliptic flow measurements for dileptons,combined with those of hadrons and direct photons, are a powerful tool for mapping the time-evolution of heavy-ion collisions.

A contribution to design life and life cycle considerations of structures
Creators: name: Schmalz, Thomas Christopher
Publisher: name: University of British Columbia
Year: 2009

description: The cost of a structure throughout its entire useful life has become an important issue in light of the deteriorating infrastructure and skyrocketing maintenance costs. As a result there has been an emergence of research interest in the field of life cycle analysis. In the last few decades researchers have begun to investigate the service life of existing structures which suffer from a real and perceived lack of performance. To address this issue, it has been suggested that, as part of the design process, more emphasis should be given to in-service performance of a structure which could possibly be based on design life concepts. Applying such concepts, considering the numerous variables and parameters involved, is undoubtedly a complex issue. This thesis summarizes the findings of recent research by the author, showing alternative approaches to the consideration of design life concepts as well as some discussion of the difficulties associated with them. Case studies are presented from the aerospace and nuclear industries, who have been applying design life considerations in one form or another for quite some time. Applicability of the methods used in these two industries to civil engineering structures have been considered and are explained. In considering civil engineering applications, the life span of a structure was broken up into the typical stages of progression, i.e. conceptual design, final design, construction, maintenance and repair, with the various influences identified and discussed at each of these stages. It followed from this research that quality control and quality assurance procedures at the design and construction stage have considerable influence on the design life of a structure. It was found that further research and development in these areas is required to propose a practical and effective means of assessing the durability of a structure.

description: Η αρχή της προφύλαξης χάραξε ένα νέο πεδίο στο Δίκαιο Περιβάλλοντος, εισάγοντας σε αυτό την έννοια της επιστημονικής αβεβαιότητας. Παρά τη ρητή κατοχύρωσή της αρχής στην ενωσιακή έννομη τάξη και τη συνακόλουθη εισχώρησή της στην ελληνική έννομη τάξη, η αρχή της προφύλαξης παραμένει αμφιλεγόμενη. Το βασικό ερώτημα που προσεγγίζεται είναι εάν η αρχή της προφύλαξης όπως έχει εφαρμοσθεί αφ’ ενός στην ελληνική και αφ’ ετέρου στην ενωσιακή έννομη τάξη έχει αναπτύξει εκείνα τα κανονιστικά θεμέλια, τα οποία της επιτρέπουν να συμβάλει στην επίτευξη υψηλού επιπέδου προστασίας για το περιβάλλον ή εάν η ασάφεια που περιβάλλει την εν λόγω αρχή μπορεί να αποτελέσει πρόσφορο πεδίο για τη λήψη αυθαίρετων αποφάσεων. Προς το σκοπό τούτο, στην εργασία οριοθετείται το εννοιολογικό περιεχόμενο της αρχής της προφύλαξης, όπως έχει διατυπωθεί στο θετικό δίκαιο και όπως έχει διαπλαστεί από το Δικαστή της Ένωσης, αναλύεται η νομική της φύση και μελετώνται τα στάδια εφαρμογής της. Τέλος, αναλύονται ζητήματα που έχουν ανακύψει κατά τη νομολογιακή προσέγγιση της αρχής αφ’ ενός από το Συμβούλιο της Επικρατείας και αφ’ ετέρου από το Δικαστήριο της Ευρωπαϊκής Ένωσης, καταλήγοντας σε μία κριτική αποτίμηση της αρχής ως προς τη μέχρι τώρα εφαρμογή της.
description: The precautionary principle has determined a new field in Environmental Law, introducing the notion of scientific uncertainty to it. Despite its explicit enshrinement in the E.U. legal order and its concomitant penetration into the Greek legal order, the precautionary principle remains controversial. The basic question approached is whether the precautionary principle, as it is implemented within the Greek and the E.U. legal order has developed the normative foundations that will permit the principle to help achieve the aim of a high level of environmental protection or whether the vagueness of this principle can lead to arbitrary decision making. For this purpose, the dissertation deals with the conceptual content of the precautionary principle, as it is stated in positive law and as it is edified by the judge of the E.U., analyses its legal nature and examines the conditions of its implementation. Finally, it examines issues that have emerged through the interpretation of the principle in the Greek Council of State (Symvoulio tis Epikrateias) and the European Court of Justice case-law, concluding to a critical analysis regarding the implementation of the precautionary principle up to now.

description: The present diploma thesis aims at developing automation software for an electromagnetic interference (EMI) receiver using Matlab in order to perform remote controlled electromagnetic compatibility (EMC) measurements. At first, the theoretical background is presented. In this is given the definition of terms of electromagnetic interference, electromagnetic immunity and electromagnetic compatibility. Possible sources and propagation mechanisms of electromagnetic interference are described, as well as the measures that must be taken to ensure the electromagnetic compatibility. Then, it is made distinction between compliance and pre-compliance testing. Also, the equipment, the environment and the preparation of electromagnetic interference measurements are considered and examined. Following the above, we study the hardware and software used to achieve remote control of EMI receiver from the computer to perform automated measurements. Finally, the Matlab implemented program is presented and examples of typical conducted interference control of DUTs in accordance with the technical standards that match specific testing equipment are performed.

description: Agricultural ecosystems provide a number of services that add greatly to the wellbeing of society. The most obvious services provided are the many forms of farm produce that are purchased and consumed. These ‘provisioning services’ are traded in established markets and their price often provides an indication of their value to society. Agroecosystems also generate many ecosystem services and disservices which are not valued by any established market. These non-market beneficial ecosystem services from agricultural landscapes include carbon sequestration, regulation of soil fertility and landscape and cultural services such as recreational opportunities on farmland. Disservices include nutrient runoff and greenhouse gas emissions. This paper provides an initial assessment of the value of Ireland’s agroecosystem services and disservices. Hydrological catchment units provide the spatial boundaries for case studies and an ecosystem service framework known as the Common International Classification of Ecosystem Services (CICES) is used to identify the relevant ecosystem services and disservices. A variety of indicators are employed to measure the level of ecosystem service or disservice generated. The values (or costs) of a number of ecosystem services are estimated and the contribution of Irish Agricultural in terms of ecosystem service benefits to society is found to be substantial.

description: Η παρούσα εργασία εξετάζει τη διαμόρφωση της Βυζαντινής τέχνης μέσα από τις τεχνικές, τις τεχνοτροπίες και τα υλικά από τον 6ο αι. μέχρι και την Άλωση το 1453. Αναφέρονται οι πηγές της και μέσα από μια σύντομη χρονολογική διαίρεση των περιόδων της ( Πρώιμη Βυζαντινή περίοδος, Μέση Και Ύστερη Βυζαντινή περίοδος ) γίνεται αναφορά στα σημαντικότερα γεγονότα καθεμίας. Στο θέμα των τεχνικών ερευνάτε πως η τεχνική της αυγοτέμπερας διαδέχεται την τεχνική της εγκαυστικής αλλά και τι ακριβώς είναι η καθεμιά ξεχωριστά. Παρουσιάζονται οι διάφορες τεχνοτροπίες όπως αυτές εμφανίζονται στην πορεία αυτών των αιώνων και συγκεκριμένα η Μακεδονική Αναγέννηση, η Κομνήνεια τεχνοτροπία, Η Παλαιολόγεια Αναγέννηση και η Μακεδονική και Κρητική Σχολή. Γίνεται επίσης μια αναλυτική περιγραφή όσον αφορά τα υλικά κατά τη Βυζαντινή περίοδο αλλά και τον τρόπο κατασκευής των φυσικών υλικών σύμφωνα με τον Διονύσιο εκ Φουρνά ( π. χ. κονδύλια, κάρβουνα, βερνίκια, κόλλες κ. .α. ). Τέλος, εξετάζεται και η γραμμή στο Βυζαντινό ζωγραφικό σύστημα.
description: The present dissertation is about the formation of the Byzantine art through the techniques, the styles and the materials from the 6th century to the Fall of the Constantinople in 1453. The sources are mentioned (Early Byzantine, Middle and Latter Byzantine period) as well as the most important events in each of them. As far as the techniques are concerned we examine the way the technique of egg - tempera follows that of the encaustic and we focus on each one of them individually. The various styles are presented as they appear through these centuries. There is, also, a thorough description as to the materials during the Byzantine period and the way the natural materials were constructed according to Dionisios from Fourna (eg. the stylus, coals, paints, glue etc) In conclusion, we examine the line in the byzantine painting system

description: Habitat loss and degradation are recognised as the most important causes of species decline and extinction in marine ecosystems. It is also widely recognised that a range of restoration actions are now essential to halt further decline. From a policy perspective, demonstration that restoration activity is in the interest of society is an important goal. In this paper, the welfare impacts of restoring Norwegian kelp forests to areas where they once were dominant but which now lie barren are estimated using the discrete choice modelling approach. The paper also examines if more direct contact with the environmental good under investigation influences respondents’ willingness to pay to restore ecosystem features. The results indicate a positive and significant marginal societal willingness to pay for the ecosystem services associated with kelp forest restoration. The enhanced biodiversity levels as a result of the restoration activity are the most highly valued by the Norwegian public although the size of the area restored is more highly valued by respondents who are active marine environment users. It is argued that without incorporating these non-market values into the decision making process marine policy decisions may be made that are not in fact in the best interest of society.

description: The search for extraterrestrial intelligence (SETI) has been conducted for nearly 60 years. A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative energy outward as an energy source for an advanced civilisation, is one of the main targets of SETI. In this study, we discuss whether building a Dyson Sphere around a black hole is effective. We consider six energy sources: (i) the cosmic microwave background, (ii) the Hawking radiation, (iii) an accretion disk, (iv) Bondi accretion, (v) a corona, and (vi) relativistic jets. To develop future civilisations (for example, a Type II civilisation), $4\times10^{26}\,{\rm W}$($1\,{\rm L_{\odot}}$) is expected to be needed. Among (iii) to (vi), the largest luminosity can be collected from an accretion disk, reaching $10^{5}\,{\rm L_{\odot}}$, enough to maintain a Type II civilisation. Moreover, if a Dyson Sphere collects not only the electromagnetic radiation but also other types of energy (e.g., kinetic energy) from the jets, the total collected energy would be approximately 5 times larger. Considering the emission from a Dyson Sphere, our results show that the Dyson Sphere around a stellar-mass black hole in the Milky Way ($10\,\rm kpc$ away from us) is detectable in the ultraviolet$(\rm 10-400\,{\rm nm)}$, optical$(\rm 400-760\,{\rm nm)}$, near-infrared($\rm 760\,{\rm nm}-5\,{\rm μm}$), and mid-infrared($\rm 5-40\,{\rm μm}$) wavelengths via the waste heat radiation using current telescopes such as Galaxy Evolution Explorer Ultraviolet Sky Surveys. Performing model fitting to observed spectral energy distributions and measuring the variability of radial velocity may help us to identify these possible artificial structures.

description: Direct photon spectra measured at small $p_T$ in p+p, d+Au and Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV are presented. Several measurement techniques including statistical subtraction, tagging, and internal and external conversion were applied and found to produce consistent results. The p+p and d+Au results are found to be in very good agreement with pQCD predictions over the entire $p_T$ range. No excess of direct photons in Au+Au collisions with respect to binary scaled d+Au data is observed within systematic errors.

description: Αντικείμενο της παρούσας διπλωματικής εργασίας αποτελεί η μελέτη των δυνάμενων να επιβληθούν σε ανήλικους κατηγορούμενους μέτρων δικονομικού καταναγκασμού. Με δεδομένη μάλιστα την σταδιακή θέσπιση της δυνατότητας επιβολής των ήδη υφιστάμενων μέτρων δικονομικού καταναγκασμού στους ανηλίκους, ήτοι της προσωρινής κράτησης και των περιοριστικών όρων, η δομή της παρούσας εργασίας διαρθρώνεται, ακολουθώντας την ιστορική πορεία της καθιέρωσης του κάθε μέτρου, ξεκινώντας από την προσωρινή κράτηση, η δυνατότητα επιβολής της οποίας σε ανήλικους κατηγορούμενους συναντάται για πρώτη φορά στον ν. 1135/1955. Ακολουθεί η καθιέρωση της δυνατότητας επιβολής περιοριστικών όρων στους ανηλίκους με τον ν. 2408/1996 και στην συνέχεια η εισαγωγή με το ν. 3189/2003 της επιβολής των αναμορφωτικών μέτρων του άρθρου 122 ΠΚ, ως περιοριστικών όρων. Κύριος άξονας της παρούσας θεματικής είναι η ανάδειξη των ιδιαίτερων ρυθμίσεων που αφορούν τους ανήλικους παραβάτες, οι οποίες ακροβατούν μεταξύ ενός προστατευτικού δικαίου ανηλίκων, το οποίο επιφυλάσσει ευνοϊκή μεταχείριση στους ανήλικους, πρεσβεύοντας την αγωγή έναντι της τιμωρίας και ενός αμιγώς περιοριστικού της ελευθερίας πλέγματος διατάξεων, όπως είναι το ρυθμιστικό των μέτρων δικονομικού καταναγκασμού νομικό πλαίσιο. Για την πληρότητα της παρούσας εργασίας, θίγονται ακροθιγώς και ορισμένες προβληματικές του δικαίου της προσωρινής κράτησης εν γένει, για τις οποίες μολονότι δεν υπάρχουν ιδιαίτερες για τους ανήλικους ρυθμίσεις, θεωρούνται αναπόσπαστο κομμάτι αυτής, όπως είναι τα μέσα άμυνας κατά των επιβληθέντων μέτρων δικονομικού καταναγκασμού και η συρροή περισσοτέρων ενταλμάτων προσωρινής κράτησης επί αληθινής πραγματικής συρροής εγκλημάτων.
description: The purpose of the present thesis is to examine the procedural coercion measures that could be imposed on criminal responsible minors. The structure of the thesis is in line with the gradual introduction of the following measures: custody, introduced in 1955 (Law No. 1135/1955), restrictive conditions on minors (Law No. 2408/1996) and the correctional measures enumerated on article 122 of the Greek penal code, as restrictive conditions (Law No. 3189/2003). The main objective of this thesis is to highlight the specific legislative provisions for juvenile offenders, in search for a fine balance between the protective character of juvenile penal law, which favors education against punishment and the mere restrictive of personal freedom character of the procedural coercion measures legal framework. Certain issues of the detention law framework, such as the defense against an (already) imposed juridical coercion measure and the cumulative detention warrants, are also briefly raised, for the completeness of the present thesis.

description: Millimetre continuum observations of debris discs can provide insights into the physical and dynamical properties of the unseen planetesimals that these discs host. The material properties and collisional models of planetesimals leave their signature on the grain size distribution, which can be traced through the millimetre spectral index. We present 8.8 mm observations of the debris discs HD 48370, CPD 72 2713, HD 131488, and HD 32297 using the Australian Telescope Compact Array (ATCA) as part of the PLanetesimals Around TYpicalPre-main seqUence Stars (PLATYPUS) survey. We detect all four targets with a characteristic beam size of 5 arcseconds and derive a grain size distribution parameter that is consistent with collisional cascade models and theoretical predictions for parent planetesimal bodies where binding is dominated by self-gravity. We combine our sample with 19 other millimetre-wavelength detected debris discs from the literature and calculate a weighted mean grain size power law index which is close to analytical predictions for a classical steady state collisional cascade model. We suggest the possibility of two distributions of q in our debris disc sample; a broad distribution (where q is approximately 3.2 to 3.7) for "typical" debris discs (gas-poor/non-detection), and a narrow distribution (where q is less than 3.2) for bright gas-rich discs. Or alternatively, we suggest that there exists an observational bias between the grain size distribution parameter and absolute flux which may be attributed to the detection rates of faint debris discs at cm wavelengths.

description: Fully adaptive computations of the resistive magnetohydrodynamic (MHD) equations are presented in two and three space dimensions using a finite volume discretization on locally refined dyadic grids. Divergence cleaning is used to control the incompressibility constraint of the magnetic field. For automatic grid adaptation a cell-averaged multiresolution analysis is applied which guarantees the precision of the adaptive computations, while reducing CPU time and memory requirements. Implementation issues of the open source code CARMEN-MHD are discussed. To illustrate its precision and efficiency different benchmark computations including shock-cloud interaction and magnetic reconnection are presented.
