description: This paper considers the trouble of the usage of approximate strategies for realizing the neural controllers for
nonlinear SISO systems. In this paper, we introduce the nonlinear autoregressive moving average (NARMA-L2)
model which might be approximations to the NARMA model. The nonlinear autoregressive moving average
(NARMA-L2) model is an precise illustration of the input–output behavior of finite-dimensional nonlinear discrete
time dynamical systems in a neighborhood of the equilibrium state. However, it isn't always handy for purposes of
neural networks due to its nonlinear dependence on the manipulate input. In this paper, nerves system based arm
position sensor device is used to degree the precise arm function for nerve patients the use of the proposed systems.
In this paper, neural network controller is designed with NARMA-L2 model, neural network controller is designed
with NARMA-L2 model system identification based predictive controller and neural network controller is designed
with NARMA-L2 model based model reference adaptive control system. Hence, quite regularly, approximate
techniques are used for figuring out the neural controllers to conquer computational complexity. Comparison were
made among the neural network controller with NARMA-L2 model, neural network controller with NARMA-L2
model system identification based predictive controller and neural network controller with NARMA-L2 model
reference based adaptive control for the preferred input arm function (step, sine wave and random signals). The
comparative simulation result shows the effectiveness of the system with a neural network controller with NARMAL2 model based model reference adaptive control system.

description: Quantum spin-liquids are strongly correlated phases of matter displaying a highly entangled ground state. Due to their unconventional nature, finding experimental signatures of these states has proven to be a remarkable challenge. Here we show that the effects of local impurities can provide strong signatures of a Dirac quantum spin-liquid state. Focusing on a gapless Dirac quantum spin-liquid state as realized in NaYbO$_2$, we show that single magnetic impurity coupled to the quantum spin-liquid state creates a resonant spinon peak at zero frequency, coexisting the original Dirac spinons. We explore the spatial dependence of this zero-bias resonance, and show how different zero modes stemming from several impurities interfere. We finally address how such spinon zero-mode resonances can be experimentally probed with inelastic spectroscopy and electrically-driven paramagnetic resonance with scanning tunnel microscopy. Our results put forward impurity engineering as a means of identifying Dirac quantum spin-liquids with scanning probe techniques, highlighting the dramatic impact of magnetic impurities in a macroscopically entangled many-body ground state.

description: Changes in trade institutions, such as the abolishment of tariff barriers, have a potentially strong impact on economic development. The Zollverein, the 1834 customs union between German states, erased borders in much of central Europe. This paper investigates the Zollverein's economic impact through a study of urban population and its growth in the German state of Saxony. A model of the effect of market access on urban growth is combined with an extensive data set on town populations in Saxony and its neighbors as well as an improved distance measure based on GIS techniques, which take into account elevation patterns, roads, and rivers. The results show that Zollverein membership led to significantly higher growth for towns close to the border with fellow Zollverein member Thuringia. They also illustrate that natural resources affect town size but not the growth pattern after the Zollverein. The effects of changes in market access were reinforced through the impact on market access in other towns and they were stronger for larger towns as well. Migration was the predominant source of the differential growth pattern.

description: Group liability in microcredit purports to improve repayment rates through peer screening, monitoring, and enforcement. However, it may create excessive pressure, and discourage reliable clients from borrowing. Two randomized trials tested the overall effect, as well as specific mechanisms. The first removed group liability from pre-existing groups and the second randomly assigned villages to either group or individual liability loans. In both, groups still held weekly meetings. We find no increase in default and larger groups after three years in pre-existing areas, and no change in default but fewer groups created after two years in the expansion areas.

description: Van der Waals heteroepitaxy allows deterministic control over lattice mismatch or azimuthal orientation between atomic layers to produce long wavelength superlattices. The resulting electronic phases depend critically on the superlattice periodicity as well as localized structural deformations that introduce disorder and strain. Here, we introduce Bragg interferometry, based on four-dimensional scanning transmission electron microscopy, to capture atomic displacement fields in twisted bilayer graphene with twist angles < 2°. Nanoscale spatial fluctuations in twist angle and uniaxial heterostrain are statistically evaluated, revealing the prevalence of short-range disorder in this class of materials. By quantitatively mapping strain tensor fields we uncover two distinct regimes of structural relaxation -- in contrast to previous models depicting a single continuous process -- and we disentangle the electronic contributions of the rotation modes that comprise this relaxation. Further, we find that applied heterostrain accumulates anisotropically in saddle point regions to generate distinctive striped shear strain phases. Our results thus establish the reconstruction mechanics underpinning the twist angle dependent electronic behaviour of twisted bilayer graphene, and provide a new framework for directly visualizing structural relaxation, disorder, and strain in any moiré material.

description: Continuous Stirred Tank Reactor (CSTR) is amajorarea in process, chemical and control engineering. In this paper, PID
and MPC controllers are designed for CSTR in order to analyze the output concentration of the system by comparing
the two proposed systems using Matlab/Simulink. Comparison have been made using two desired concentration input
(Random reference and step) signals with and without input side disturbance (Flow rate error). The simulation result
shows that the continuous stirred tank reactor with MPC controller have better response in minimizing the overshoot
and tracking the desired concentration for the system without input disturbance and with the effect of the disturbance
makes the continuous stirred tank reactor with MPC controller output with small fluctuations and still better than the
continuous stirred tank reactor with PID controller. Finally the comparative analysis and simulation results prove the
effectiveness of the continuous stirred tank reactor with MPC controller.

description: Beim Entwickeln von Grafik-Engines liegt des Augenmerk meist auf der Performance, gemessen an der Anzahl Frames pro Sekunde, die die Engine zu generieren vermag. Dieser starke Fokus auf die Effizienz führt in vielen Fällen dazu, dass sich auch performancerelevante Details der Implementierung in der API wiederfinden um eine möglichst effiziente Verwendeung des Produkts zu ermöglichen. Durch diese Herangehensweise wird für die Verwendung solcher APIs einiges an Wissen in Teilbereichen der Grafikprogrammierung vorausgesetzt. Wir wollen im Rahmen dieser Arbeit die Notwendigkeit dieser Herangehensweise überprüfen. Wir wollen herausfinden, ob eine Reduktion des benötigten Fachwissens einen direkten Performance-Verlust zur Folge hat. Wir haben zu diesem Zweck drei quelloffene Grafik-Engines analysiert, um Konzepte zu identifizieren, die außerhalb der Grafikdomäne wenig Verbreitung finden. Auf Basis unserer Erkenntnisse haben wir PURGE - eine eigene Grafik-API - entwickelt, die auf die Verwendung durch Entwickler ausgerichtet ist, die wenig bis überhaupt keine Erfahrung in dieser Domäne besitzen. Anschließende Tests haben ergeben, dass diese zusätzliche Software-Ebene kaum Auswirkungen auf die Performance von visuell einfachen Applikationen hat.
description: When referring to the quality of 3D graphics engines, the central point of interest is usually computational performance. This very intense occupation with this aspect of such graphics engines leads to the exposure of performance-relevant implementation specifics in the API, to allow performance-aware usage of the product, but limiting the audience to those knowledgeable about the details of graphics engine implementation. Our aim was to evaluate whether the amount of domain knowledge in existing graphics engine APIs was justified; whether it would be possible to reduce the knowledge expected from the user of such APIs without sacrificing too much performance. We have analyzed three different open source graphics engines to identify elements that are less known outside of the graphics development domain. Based on our findings, we have created PURGE, our own high-level API for graphics development, which makes use of other libraries for the actual rendering. We have found that the performance impact of the added software layer was not noticeable during the development of simple test scenes, which we assume to be the prior concern of developers who are starting graphics development for the first time.

description: Machine learning models are increasingly being used in important decision-making software such as approving bank loans, recommending criminal sentencing, hiring employees, and so on. It is important to ensure the fairness of these models so that no discrimination is made based on protected attribute (e.g., race, sex, age) while decision making. Algorithms have been developed to measure unfairness and mitigate them to a certain extent. In this paper, we have focused on the empirical evaluation of fairness and mitigations on real-world machine learning models. We have created a benchmark of 40 top-rated models from Kaggle used for 5 different tasks, and then using a comprehensive set of fairness metrics, evaluated their fairness. Then, we have applied 7 mitigation techniques on these models and analyzed the fairness, mitigation results, and impacts on performance. We have found that some model optimization techniques result in inducing unfairness in the models. On the other hand, although there are some fairness control mechanisms in machine learning libraries, they are not documented. The mitigation algorithm also exhibit common patterns such as mitigation in the post-processing is often costly (in terms of performance) and mitigation in the pre-processing stage is preferred in most cases. We have also presented different trade-off choices of fairness mitigation decisions. Our study suggests future research directions to reduce the gap between theoretical fairness aware algorithms and the software engineering methods to leverage them in practice.

description: L'aumento continuo e spettacolare del dollaro sul mercato globale dei cambi, nonostante l'altrettanto spettacolare disavanzo delle partite correnti della bilancia dei pagamenti, è una cosa che nessun economista avrebbe sognato . Tutti saranno d'accordo che la risposta al puzzle sta nel fatto che le operazioni in conto corrente costituiscono ormai solo una piccola parte dei movimenti valutari lordi, dominata di fattop da movimenti di capitali. Ciò che deve essere spiegato allora è l'enorme volume di capitale netto totale che finanzia il deficit. Il presente lavoro considera questo paradosso, il ruolo del dollaro nel sistema monetario mondiale e le prospettive a medio e lungo termine per il sistema finanziario mondiale. The continuous and spectacular rise of the dollar on the global foreign exchange market, despite the equally spectacular current account deficit of the U.S. balance of payments, is something that no economist would have dreamed to be possible. Everyone will agree that the answer to the puzzle lies in the fact that the transactions in the current account now constitute only a small part of the gross currency movements, in fact dominated by capital movements. What needs to be explained then is the sheer volume of the total net capital that finances the deficit. The present work considers this paradox, the dollar’s role in the world monetary system and medium and long-term perspectives for the world financial system. JEL: E52, F31, E42,

description: Motivated by the dynamics in the deep interiors of many stars, we study the interaction between overshooting convection and the large-scale poloidal fields residing in radiative zones. We have run a suite of 3D Boussinesq numerical calculations in a spherical shell that consists of a convection zone with an underlying stable region that initially compactly contains a dipole field. By varying the strength of the convective driving, we find that, in the less turbulent regime, convection acts as turbulent diffusion that removes the field faster than solely molecular diffusion would do. However, in the more turbulent regime, turbulent pumping becomes more efficient and partially counteracts turbulent diffusion, leading to a local accumulation of the field below the overshoot region. These simulations suggest that dipole fields might be confined in underlying stable regions by highly turbulent convective motions at stellar parameters. The confinement is of large-scale field in an average sense and we show that it is reasonably modeled by mean-field ideas. Our findings are particularly interesting for certain models of the Sun, which require a large-scale, poloidal magnetic field to be confined in the solar radiative zone in order to explain simultaneously the uniform rotation of the latter and the thinness of the solar tachocline.

description: The Third EGRET Catalog (3EG) lists 66 high-confidence identifications of sources with Active Galactic Nuclei (AGN). All are classified as belonging to the blazar class, with the only exception of the nearby radio galaxy Centaurus A. We report and strengthen the association of another radio galaxy, 3C111, with the EGRET source 3EG J0416+3650. At the time of the compilation of the 3EG catalogue, 3C111 has been considered as a low-confidence counterpart of 3EGJ0416+3650, being located outside the 99% gamma-ray probability contour. Since this first suggestion, no other counterparts have been reported nor the EGRET error box has been searched for likely candidates. 3C111 has never been considerated or cited in literature as a radiogalaxy counterpart of an EGRET source. We report a detailed multiwavelength study of the EGRET error box as well as for the first time the overall spectral energy distribution of 3C111, which appears to be intriguingly similar to those of blazars, suggesting that the radiogalaxy 3C111 is the likely counterpart of 3EG J0416+3650.

description: We propose a new measure for food prices to further examine the impact of changes in food prices and real income on individuals’ eating decisions and weight. We calculate price per calorie for food consumed away from home and food consumed at home as the dollar amount spent by households on each food category divided by the number of calories consumed. We use our newly constructed time series for price per calorie as an input into a neoclassical model of eating decisions and weight. Our goal is to propose a quantitative explanation for the increase in calories consumed away from home as well as changes in weight for men and women 1971 and 2006. We find that prices determine the allocation of calories across food types, while income determines the total number of calories consumed and thus individuals' weight. Based on our results, we share the view that taxes on food will impact what people eat but will have limited effect on reducing the population body-mass index or the obesity prevalence.

Comment on Analysis of Scissors Cutting Paper at Super Luminal Speeds

description: In a recent paper, it was demonstrated that the popular legend that scissors can cut paper at super luminal speeds is indeed correct. In this comment we make this additional observation that when the cutting speed is super luminal, the direction of the cutting of the paper as observed by observers in the inertial frame stationary with respect to the blade of the scissors and the direction of the cutting of the paper as observed by observers in the inertial frame stationary with respect to the paper are opposite. This follows from the relativity of simultaneity, and the fact that space-time points that are separated beyond reach at sub-luminal speeds exhibit reversal in time order as observed by different inertial frames. The fact that the paper was cut in opposite directions as observed by the paper and scissors, can be interesting facet for students of Physics.

description: Die Integration von Kindern und Jugendlichen mit psychischen Traumata in unsere beiden Sonderschulheime der Stiftung „Gott hilft“ und ihre Beschulung zeigte sich bis anhin als Herausforderung. Nicht selten reichte der normale sonderpädagogische Rahmen nicht aus und es folgte eine Neuplatzierung in einer nächsten Institution. Durch den stärkeren Ausbau der Integrationsarbeit an den öffentlichen Schulen des Kantons Graubünden wird sich unser pädagogisches Arbeiten noch stärker in diese Richtung verändern. Den Weg der Sonderschulung werden vermehrt besonders belastete Kinder und Jugendliche einschlagen, bei denen alle Möglichkeiten der örtlichen Integration ausgeschöpft wurden. Es stellt sich nun die Frage, wie wir auf diese Begebenheit reagieren und welche Anpassungen wir in unserer pädagogischen Praxis und auf institutioneller Ebene vornehmen müssen, damit solche Kinder und Jugendliche nachhaltig in die Sonderschulheime Zizers und Scharans integriert werden können. Die vorliegende Arbeit soll eine Antwort auf diese Frage geben. Dazu wurde ein traumapädagogisches Konzept erstellt, das auf den Erkenntnissen und der Arbeitsweise der Traumapädagogik basiert. Dieses wurde den Lehrpersonen, der Heimleitung und der pädagogischen Leitung der Stiftung vorgestellt und anhand von Interviews aufgrund ihrer Erfahrung evaluiert. Daraus entstanden drei traumapädagogische Schulmodelle, die wichtige Bedürfnisse auf der Ebene der Lehrpersonen und auf institutioneller Ebene berücksichtigen. Zwei davon kommen für die Betriebe Zizers und Scharans in Frage und werden als Beantwortung der Hauptfrage am Ende der Arbeit vorgestellt.

description: Multi-contrast magnetic resonance (MR) image registration is useful in the clinic to achieve fast and accurate imaging-based disease diagnosis and treatment planning. Nevertheless, the efficiency and performance of the existing registration algorithms can still be improved. In this paper, we propose a novel unsupervised learning-based framework to achieve accurate and efficient multi-contrast MR image registrations. Specifically, an end-to-end coarse-to-fine network architecture consisting of affine and deformable transformations is designed to improve the robustness and achieve end-to-end registration. Furthermore, a dual consistency constraint and a new prior knowledge-based loss function are developed to enhance the registration performances. The proposed method has been evaluated on a clinical dataset containing 555 cases, and encouraging performances have been achieved. Compared to the commonly utilized registration methods, including VoxelMorph, SyN, and LT-Net, the proposed method achieves better registration performance with a Dice score of 0.8397 in identifying stroke lesions. With regards to the registration speed, our method is about 10 times faster than the most competitive method of SyN (Affine) when testing on a CPU. Moreover, we prove that our method can still perform well on more challenging tasks with lacking scanning information data, showing high robustness for the clinical application.
Formal equivalence checking of software specifications vs. hardware implementations
Creators: name: Feng, Xiushan
Publisher: name: University of British Columbia
Year: 2011

description: Ever-growing complexity is forcing logic design to move above the register transfer level (RTL). For example, functional specifications are being written in software. These specifications are written for clarity, and are not optimized or intended for synthesis. Since the software is the target of functional validation, equivalence verification between the software specification and the RTL implementation is needed. This thesis introduces new techniques to reduce the complexity of this verification and increase the capability of current verification techniques. The first contribution improves the efficiency of sequential equivalence verification. I introduce a partitioned model checking approach using Annotated Control Flow Graphs (ACFG) to represent software specifications for sequential circuits. The approach partitions the software and hardware states based on the structure of the ACFG, and uses the flow and the edge annotations in the ACFG to guide the state-space exploration. Experimental results show that the new partitioned model checking approach runs faster than the standard global reachability analysis. The second contribution increases the scalability of combinational equivalence verification between a high-level software specification and RTL. Unlike conventional RTL-to-gate combinational equivalence verification, there are fewer structural similarities between the two models, and it is harder to find equivalent points. Furthermore, each path through the software can compute a different result, and there are an exponential number of paths. I first adapt the concept of cutpoints from hardware verification and define the analogous concept of software cutpoints, then implement a proof-of-concept cutpoint approach in my verification tool for the TI C6x family of DSPs. Experimental results show large improvements in both runtime and memory usage. Next, I introduce outpoints into the equivalence verification of software specifications vs. hardware implementations. I present a novel way to introduce cutpoints early, during the analysis of the software, rather than after a low-level hardware-equivalent has been generated, thereby avoiding the exponential enumeration of software paths as well as the logic blow-up of tracking merged paths. I evaluate this method on a challenge problem suggested by colleagues in industry. Experimental results show large improvements in runtime and memory usage due to the early cutpoint insertion.

Questo è confermato dal considerare il problema del debito internazionale tra la prima e la seconda guerra mondiale . La principale differenza tra allora e adesso è che il periodo tra le due guerre fu un periodo di transizione da un sistema di commercio dominato daòòa sterlina ad uno dominato dal dollaro statunitense . Molti dei problemi di oggi derivano da questa continua dominazione dollaro Considerable attention has recently been paid to the current problem of third world debt and its implications for the international banking system. A review of similar events at previous times in the past shows that operators in international financial markets have very short memories, since most of the aspects of the current crisis have occurred in the past. This is borne out by considering the international debt problem between the first and second world wars. The major difference between then and now is that the interwar period was a time of transition from a sterling-dominated trading system to one dominated by the US dollar. Many of today's problems stem from this continuing dollar domination. JEL: N24

description: Biosensors exploiting long-range surface plasmon polariton (LRSPP) waveguides comprised of Au stripes embedded in Cytop with integrated and encapsulated microfluidic channels are fabricated and demonstrated. A fabrication approach was devised where the lower cladding and recessed Au stripes are fabricated on a Si substrate, and the upper cladding and microfluidic channels are fabricated on a glass substrate, followed by wafer bonding to assemble the wafers into complete structures. The bond is centered over the full length of the optical path, yet no evidence of optical scattering or excess loss due to the bond could be observed, and no evidence of a bonding interface could be discerned from high-magnification cross-sectional images. We also demonstrate wafer-scale fabrication of in-plane microfluidic inlets and outlets, along with a fixture for fluidic edge coupling that provides sealed interfaces to external fluidic tubing and components. In-plane microfluidic interfaces are automatically defined along chip facets upon wafer dicing, precluding the need to drill through holes in lids. The performance of the chips was assessed by measuring the attenuation of LRSPPs on fully cladded reference waveguides, on waveguides passing through microfluidic channels, and by measuring the response of sensors to changes in refractive index produced by injecting various sensing solutions. Our fabrication approach based on wafer bonding and in-plane fluidic interfacing is compelling for low-cost high-volume manufacturing.

improving road managing and ride comfort. This paper offers the development of mathematical modelling and
design of a neural network control approach. The paper will begin with a mathematical model designing primarily
based at the parameters of the active suspension system. A nonlinear three by four-way valve-piston hydraulic
actuator became advanced which will make the suspension system under the active condition. Then, the model can
be analyzed thru MATLAB/Simulink software program. Finally, the NARMA-L2, model reference and predictive
controllers are designed for the active suspension system. The results are acquired after designing the simulation of
the quarter-car nonlinear active suspension system. From the simulation end result using MATLAB/Simulink, the
response of the system might be as compared between the nonlinear active suspension system with NARMA-L2,
model reference and predictive controllers. Besides that, the evaluation has been made between the proposed
controllers thru the characteristics of the manage objectives suspension deflection, body acceleration and body travel
of the active suspension system. . As a conclusion, designing a nonlinear active suspension system with a nonlinear
hydraulic actuator for quarter car model has improved the car performance by using a NARMA-L2 controller. The
improvements in performance will improve road handling and ride comfort performance of the active suspension
system.

description: Following the first demonstration of a levitated nanosphere cooled to the quantum ground state in 2020 [1], macroscopic quantum sensors are seemingly on the horizon. The nanosphere's large mass as compared to other quantum systems enhances the susceptibility of the nanoparticle to gravitational and inertial forces. In this viewpoint we describe the features of experiments with optically levitated nanoparticles [2] and their proposed utility for acceleration sensing. Unique to the levitated nanoparticle platform is the ability to implement not only quantum noise limited transduction, predicted by quantum metrology to reach sensitivities on the order of $10^{-15}$ms$^{-2}$ [3], but also long-lived quantum spatial superpositions for enhanced gravimetry. This follows a global trend in developing sensors, such as cold-atom interferometers, that exploit superposition or entanglement. Thanks to significant commercial development of these existing quantum technologies, we discuss the feasibility of translating levitated nanoparticle research into applications.

subject: Web data extraction

description: Diese Arbeit präsentiert einen Ansatz um Daten von Mitarbeitern einer Universität und ihre berufliche Kompetenzen zu extrahieren, während man sich mit Themen wie Web-Datenextraktion Probleme wie z.B. Seitenstruktur Probleme, Dynamic Data, Unstrukturierte Daten usw. auseinandersetzen muss. Die Software die in dieser Arbeit vorgeschlagen versucht Daten zu extrahieren von Universitätsmitarbeitern und ihre berufliche Kompetenzen und das soweit möglich von den meisten Universitäten. Die Professionellen Kompetenzen der Universitätsmitarbeiter werden durch die Verwendung einer bestehenden Ontologie ermittelt, die erweitert wird um die Domäne eines Anwendungsfalls abzudecken. Diese Software wird aus zwei Teilen zusammengesetzt sein. Der erste Teil wird sich damit beschäftigen um alle nötigen Daten zu besorgen die ein Input für den zweiten Teil sein wird, welches ein Datenextrahieren ist. Es wird den SelectorGadget Bookmarklet verwenden, welches die CSS-selector Elemente bereitstellt mit denen Benutzer auswählen können welche Daten sie für die Extraktion möchten. Das andere Bookmarklet wird den Input von SelectorGadget bekommen und es dann an das Data extraction Software weiterleiten. Um das vorgeschlagene Verfahren zur Extraktion von den oben angeführten Daten zu evaluieren wird eine Umfrage durchgeführt mit Mitarbeitern eines Anwendungsfalls. Die Genauigkeit der extrahierten Kompetenzen die durch diese Arbeit ermittelt wurden wird durch den Vergleich mit Kompetenzen die aus der Umfrage gewonnen wurden gemessen.
description: This thesis presents an approach to extract University staff professional competences while dealing with Web data extraction issues like page structure problems, dynamic data, unstructured data, etc... The software which is proposed in this thesis will tend to extract University staff professional competences from most of the Universities and if it is possible to work for all. University staff professional competences will be determined by using an existing ontology which will be extended to cover the domain of an use case. That software will be composed of two parts. First part will be dealing with gathering required data which will be an input for the second part which will be a data extractor. It will use SelectorGadget bookmarklet which provides CSS-selector elements with which users can select desired data for extraction. The other bookmarklet will get the input from SelectorGadget and pass it to data extraction software. In order to evaluate the proposed method for extracting University staff professional competences the survey will be conducted with staff members of an use case. The accuracy of extracted competences obtained by the method from this thesis will be measured by comparing them with competences obtained from the survey.

description: It is well-known that the noise associated with the collection of an astronomical image by a CCD camera is, in large part, Poissonian. One would expect, therefore, that computational approaches that incorporate this a priori information will be more effective than those that do not. The Richardson-Lucy (RL) algorithm, for example, can be viewed as a maximum-likelihood (ML) method for image deblurring when the data noise is assumed to be Poissonian. Least-squares (LS) approaches, on the other hand, arises from the assumption that the noise is Gaussian with fixed variance across pixels, which is rarely accurate. Given this, it is surprising that in many cases results obtained using LS techniques are relatively insensitive to whether the noise is Poissonian or Gaussian. Furthermore, in the presence of Poisson noise, results obtained using LS techniques are often comparable with those obtained by the RL algorithm. We seek an explanation of these phenomena via an examination of the regularization properties of particular LS algorithms. In addition, a careful analysis of the RL algorithm yields an explanation as to why it is more effective than LS approaches for star-like objects, and why it provides similar reconstructions for extended objects. We finish with a convergence analysis of the RL algorithm. Numerical results are presented throughout the paper. It is important to stress that the subject treated in this paper is not academic. In fact, in comparison with many ML algorithms, the LS algorithms are much easier to use and to implement, often provide faster convergence rates, and are much more flexible regarding the incorporation of constraints on the solution. Consequently, if little to no improvement is gained in the use of an ML approach over an LS algorithm, the latter will often be the preferred approach.

description: L' articolo esamina le condizioni del FMI per la tranche di credito accordi stand-by superiori. L' FMI deve affrontare le critiche che le sue azioni recenti hanno comportato sul ' territorio a causa di errori nei prestiti di banche ai paesi del terzo mondo banche private - una questione che avrebbe potuto essere lasciata alle forze di mercato libere .Le condizioni di assistenza del FMI dovrebbero concentrarsi non sugli strumenti di politica ma su obiettivi politici , come la crescita , l'occupazione , l'inflazione e , in ultima analisi , il ripristino della bilancia dei pagamenti dei paesi. The article looks at IMF conditions for upper credit tranche stand-by arrangements. The IMF must face the criticism that its recent actions have transgressed on private banks' territory because of banks' errors in lending to third world countries - a matter that could have been left to free market forces. Conditions for IMF aid should focus not on policy instruments but on policy targets, such as growth, employment, inflation and, ultimately, restoration of countries' balance of payments positions. Conditions for IMF help should be centred squarely on the balance of payments of aid-seeking countries if a backwards trend is to be avoided. JEL: F32, F33

description: L'interesse di Joan Robinson nel problema della distribuzione del reddito e il suo disprezzo per quello che considera le teorie che hanno cercato di giustificare le distribuzioni esistenti di reddito mai segnalati . Il suo lavoro è caratterizzato da una forte inclinazione per chiari argomenti ben ragionati che non lasciavano spazio per sciatte abitudini di pensiero . La portata ampia e la quantità di scritti di Robinson rendono difficile presentare una valutazione critica dei suoi contributi nel contesto anche di un documento lungo . Quella attuale si concentra sui suoi scritti in cinque aree principali : (i) l'economia della concorrenza imperfetta ; ( ii ) la teoria del rapporto di lavoro ; ( iii ) la teoria di accumulazione nel lungo periodo ; ( iv ) il concetto di capitale e la funzione di produzione ; e ( v ) il problema del tempo in economia che si riflette nei suoi scritti sulla storia tema contro equilibrio . Joan Robinson’s interest in the question of the distribution of income and her disdain for what she considered to be theories that tried to justify existing distributions of income never flagged. Her work is marked by a strong inclination for clear, well reasoned arguments that left no room for sloppy habits of thought. The wide scope and quantity of Robinson’s writings make it difficult to present a critical evaluation of her contributions within the context of even a lengthy paper. The present one concentrates on her writings in five main areas: (i) the economics of imperfect competition; (ii) the theory of employment; (iii) the theory of accumulation in the long run; (iv) the concept of capital and the production function; and (v) the problem of time in economics as reflected in her writings on the theme history versus equilibrium.
