The negotiated revolution in Hungary
No full textPublished online: 20 January 2012The paper is an updated version of a piece that I wrote about the Hungarian regime change of 1989 with some cautious parallels to the North African regime changes. It analyses the strategies of the opponents and the defendants of the regime, the way they have adjusted their strategies to perceived changes in geopolitical constellations and the frames they have used to mobilize support for changing or conserving the regime.

Laszlo Varga: Pedagogy, history, and legacy
No full textThe purpose of this essay is to provide a detailed exploration of the personal history, teaching techniques, and professional achievements of Laszlo Varga, a famous and important Hungarian cellist living in America.Varga is considered one of the greatest living cellists and pedagogues in America today. He now resides in Sarasota, Florida, where he teaches and writes cello ensemble arrangements. He also performs and lectures throughout the world. Very little has been written about this cello virtuoso and master teacher who grew up in Hungary and worked with such artists as Casals and Starker.Varga agreed to spend several hours with the author answering questions and discussing his own history, teaching techniques, and current projects. The author met with Varga in his Sarasota, Florida home and conducted two taped interviews with him. Subjects covered in the interview included Varga's interest in performing on a five-string cello, the main issues he covers in a student's lesson, the scale system, etudes and methods he employs, and the repertoire he favors. In addition, an important part of the interview addressed Varga's impressions and stories about the many extraordinary musicians that he has met during his career.</p
Nouvel environnement européen et stabilité de l'Europe centrale
No full textThe New European Environment and the Stability of Central Europe, by Laszlo Valki
According to the author after the withdrawal of the Soviet troops front Hungary, Czechoslovakia, the former GDR, and most probably from Poland and after the dissolution of the Warsaw Pact no power vacuum will emerge in Central Europe. There is no immediate danger of any armed conflict in the region, even not in consequence of ethnical controversies. Much more threatening are the grave economie troubles, inherited from the post-Stalinist regimes. The author is very much afraid that many tasks simply cannot be solved simultaneously, e.g. decreasing enormous debts, accomplishing privatization, creating real market conditions, ensuring energy-supply, coping with the dissolution of Comecon, in other words, to start and bring to the end the system transformation. If these historical tasks will not be solved in the next couple of years, the world has to face with serious destabilization of domestic political orders, which might lead to destabilization of international relations in Central Europe, too.Selon l'auteur, après le retrait des troupes soviétiques de Hongrie, de Tchécoslovaquie, de l'ancienne RDA, et très vraisemblablement de Pologne, et après la dissolution du pacte de Varsovie, il n'y aura pas de vide du pouvoir en Europe centrale. Il n'y a aucun danger immédiat de conflit armé dans la région, même si l'on prend en compte les querelles ethniques. Les graves problèmes économiques hérités des régimes poststaliniens représentent un danger beaucoup plus grand. La grande crainte de l'auteur est que de nombreux impératifs ne puissent tout simplement pas être respectés simultanément comme, par exemple, réduire les énormes dettes, réussir la privatisation, créer une véritable économie de marché, assurer l'approvisionnement en énergie, s'adapter à la dissolution du Come-con ; autrement dit, commencer puis mener à terme la transformation du système. Si ces impératifs d'ordre historique ne sont pas respectés au cours des quelques années à venir, le monde devra faire face à une grave déstabilisation des régimes politiques intérieurs, ce qui pourrait aussi avoir comme conséquence une déstabilisation des relations internationales en Europe centrale.Valki Laszlo.

Provenance-based trust for grid computing: Position Paper
No full textCurrent evolutions of Internet technology such as Web Services, ebXML, peer-to-peer and Grid computing all point to the development of large-scale open networks of diverse computing systems interacting with one another to perform tasks. Grid systems (and Web Services) are exemplary in this respect and are perhaps some of the first large-scale open computing systems to see widespread use - making them an important testing ground for problems in trust management which are likely to arise. From this perspective, today's grid architectures suffer from limitations, such as lack of a mechanism to trace results and lack of infrastructure to build up trust networks. These are important concerns in open grids, in which "community resources" are owned and managed by multiple stakeholders, and are dynamically organised in virtual organisations. Provenance enables users to trace how a particular result has been arrived at by identifying the individual services and the aggregation of services that produced such a particular output. Against this background, we present a research agenda to design, conceive and implement an industrial-strength open provenance architecture for grid systems. We motivate its use with three complex grid applications, namely aerospace engineering, organ transplant management and bioinformatics. Industrial-strength provenance support includes a scalable and secure architecture, an open proposal for standardising the protocols and data structures, a set of tools for configuring and using the provenance architecture, an open source reference implementation, and a deployment and validation in industrial context. The provision of such facilities will enrich grid capabilities by including new functionalities required for solving complex problems such as provenance data to provide complete audit trails of process execution and third-party analysis and auditing. As a result, we anticipate that a larger uptake of grid technology is likely to occur, since unprecedented possibilities will be offered to users and will give them a competitive edge
Destroying necessity with necessity - on Laszlo Krasznahorkai's <i>Satantango</i>
No full textIn this article, I read and analyse the novel Satantango (1985) by the Hungarian writer Laszlo Krasznahorkai's. Set in a small community in rural Eastern Hungary - before the fall of the Berlin Wall and the end of the Soviet regime - where the rain is falling incessantly, all hope has been lost, history has ended before it even began, and the houses are crumbling from the inside out, the novel is, for obvious reasons, often considered to have a tone of brutal and bleak pessimism. Robert Boyers thus talks about Krasznahorkai's 'pessimistic virtuosity' and literary realism, the sole purpose of which is disillusion. In this article, however, I would like to contest this claim and look for some paradoxical glimpses of hope hidden in the anatomy of hopelessness that the author undoubtedly makes manifest trough a radical materialism; a hope against hope. I argue that Krasznahorkai destroys necessity with necessity. To that end I will bring in the work of Ernst Bloch as well as Jacques Ranciere's book on filmmaker Bela Tarr who has adapted several of Krasznahorkai's novels for the screen.</p

Chemotherapy-based versus chemotherapy-free stem cell mobilization (± plerixafor) in multiple myeloma patients: an Italian cost-effectiveness analysis
No full textGiven the availability and efficacy of the mobilizing agent plerixafor in augmenting hematopoietic progenitor cell mobilization with granulocyte colony-stimulating factor (G-CSF), there is a strong case for comparing the cost-effectiveness of mobilization with G-CSF + cyclophosphamide versus G-CSF alone. This study investigated the cost and effectiveness (i.e., successful 4 million-CD34+ collection) of G-CSF alone versus high-dose cyclophosphamide (4 g/m2) + G-CSF mobilization (± on-demand plerixafor) in patients with multiple myeloma (MM) eligible for autograft in Italy. A decision tree-supported cost-effectiveness analysis (CEA) model in MM patients was developed from the societal perspective. The CEA model compared G-CSF alone with cyclophosphamide 4 g/m2 + G-CSF (± on-demand plerixafor) and was populated with demographic, healthcare and non-healthcare resource utilization data collected from a questionnaire administered to six Italian oncohematologists. Costs were expressed in Euro (€) 2019. The CEA model showed that G-CSF alone was strongly dominant versus cyclophosphamide + G-CSF (± on-demand plerixafor), with incremental savings of €1198.59 and an incremental probability of a successful 4 million-CD34+ apheresis (+0.052). Sensitivity analyses confirmed the robustness of the base-case results. In conclusion, chemotherapy-free mobilization (± on-demand plerixafor) is a “good value for money” option for MM patients eligible for autograft. © 2021, The Author(s)
NET PRESENT VALUE CALCULATION: REAL LIFE APPROACH
No full textNet Present Value (and IRR) is calculation considered as the most widely accepted measures of investment’s financial evaluation. Both methods apply long-term cashflows for 5 to 15 years ahead. During that period inflation certainly has an effect on both cash inflow and outflow figures. Litereture often does not take into account the inflation or suggest a simplified inflation-corrected calculation method. Author proves that it is not appropriate in case of long-term physical investments. A new method: life-long financial simulation is suggested by the author for financial evaluation of physical investments
Two investigations of compressor stability : spike stall inception and transient heat transfer effects
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Aeronautics and Astronautics, 2015.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 139-142).Two investigations of current problems in the field of compressor stability are presented. The first is of the formation of spike-type rotating stall precursors. Recently, high fidelity computations have attributed pre-cursor formation to a leading-edge separation and consequent shedding of vorticity near the rotor tip due to high incidence. This hypothesis is assessed via experiments in a low-speed compressor and a linear cascade, supported by unsteady computations. Fast-response pressure measurements at the blade tip show spike pre-cursors propagating in the cascade environment at a rate consistent with the low-speed compressor. The cascade design produces high incidence at the mid-span and fast-response velocity measurements show pre-cursor formation away from the tip region. Unsteady computations confirm leading-edge separation and vortex shedding in both the compressor and cascade. A single blade was instrumented with smoke injection at the leading-edge to visualize the separation and the effect of Reynolds number on pre-cursor formation was quantified to facilitate smoke visualization. The resultant visualizations confirm the leading-edge separation and propagation of shed vorticity. The second investigation is of the effects of heat transfer between the compressor structure and gas path during transient operation. A mean line model of an advanced, high pressure ratio compressor is extended to include the effects of heat transfer. Diabatic, transient calculations show a 9.9 point reduction in stall margin from the adiabatic case. 2.5 points are attributed to the effect of heat transfer on blade row deviation and the remainder is attributed to stage rematching. Heat transfer increases loading in the front stages and the stalling pressure ratio is set by front stage stall, suggesting heat transfer effects are greater for compressors with highly loaded front stages. Sensitivity studies of heat flow rate and deviation show a linear dependence of stall margin loss for ratios of heat flow rate to inlet stagnation enthalpy flux much less than unity.by Andras Laszlo Andor Kiss.S.M
