The aim of the paper is to develop a new nonlinear tuned vibration absorber (NLTVA) capable of mitigating the vibrations of nonlinear systems which are known to exhibit frequency-energy-dependent oscillations. A nonlinear generalization of Den Hartog’s equal-peak method is proposed to ensure equal peaks in the nonlinear frequency response for a large range of forcing amplitudes. An analytical tuning procedure is developed and provides the load-deflection characteristic of the NLTVA. Based on this prescribed relation, the NLTVA design is performed by two different approaches, namely thanks to (i) analytical formulas of uniform cantilever and doubly-clamped beams and (ii) numerical shape optimization of beams with varying width and thickness. A primary system composed of a cantilever beam with a geometrically nonlinear component at its free end serves to illustrate the proposed methodology. [less ▲]

LaTeX is a beautiful programming language. One sometimes wants to write in an easy and quick way various documents, such as letters, papers, reports, theses, and so on. Here, “one” can be a new student, an old professor, or even somebody who is not linked at all with any academic stuff. We often want special constructs in our documents. This is more difficult than basic typesetting, especially using LaTeX when you are not experienced. On one hand, scientists do not always have the time to learn another programming language, especially if they are making a PhD, or doing something else which asks for a lot of time. Using direct and working programming tricks can speed up your productivity, and make you learning better. But where can they be found? On the other hand, everybody wants to make nice documents, if possible. A nicer document attracts the reader. Evidently, “a nice document” is a subjective notion. By “nice document,” we want to speak about a document which 1. is structured in an unambiguous way, and has a clear presentation, 2. is read with pleasure, if possible. The beginner, whoever he is, often faces strange errors because he tries to teach LaTeX to do what he wants it to do. It is difficult to learn the advanced notions about LaTeX, even in an average period of time. The good books have to be found. But that is often the moment where you lack of time and that you are happy to find complete solutions. That is a moment where you tell to yourself “Is there no folk out there to give me such a trivial tip?” but nobody hears it. The aim of this book, is to avoid you these problems: you do not need to write everything from scratch, ask on various forums or Usenet groups, or even read heaps of books just to make a simple script. That is my goal. You can now continue writing your document in LaTeX’s philosophy: concentrating on your document’s content, at the place of its appearence. These reasons justify the presence of this book. I have tried to pack the most useful tricks which can enhance your documents’ content in a concise way. The aim is not to teach LaTeX programming, but to give a quick reference to all the tips and tricks that can be used if you are encountering a (difficult) problem, or simply facing a question which you cannot find the answer to. I consider that the reader is familiar with basic LATEX programming. It can be learnt from various sources (given in this book's bibliography), and many others. I hope this will give you new ideas about advanced ways to typeset text and to make different processes automatic, thus giving you more time for other activities. Many others subjects were added during Fall 2010. [less ▲]

Unsatisfactory compliance in the treatment of high blood presure is frequently due to sequential barriers, such as insufficient patient education about the illness and low motivation to receive any treatment, existence of a large gap between physicians'perceptions of the problem and clinical reality, complexity of the treatment potentially generating adverse effects, and a health care environment with few public education compaigns and incentives for better coordinated supportive care. In order to improve drug compliance, establishment of personalized plans adapted to each patient is required. First, a good doctor-patient relationship is mandatory, with regular education of the patient about hypertension and its risks, discussion about adverse drug effects, and the complexity and cost of treatment. Second, to have any chance of success, the provider should offer convenient appointments and tailor the treatment regimen to the patient's lifestyle and needs, with written instructions. Third, there is a need to promote active patient collaboration with treatment. An innovative combination of home self-measurement of blood pressure, use of new technology options, eg, texting or telemedicine, and creation of a multi-disciplinary working team can offer new, effective opportunities. This approach could reduce cardiovascular complications by improving the control of high blood pressure, and thereby the overall costs of hypertension to the health care system. [less ▲]

Imatinib has drastically changed the outcome of patients with chronic myeloid leukemia (CML), with the majority of them showing a normal life span. Recently, the development of second and third generation tyrosine kinase inhibitors (TKIs) and the possibility of treatment discontinuation made the management of these patients more challenging. In this review, practical management guidelines of CML are presented, adapted to the Belgian situation in 2014. In first line chronic phase patients, imatinib, nilotinib and dasatinib can be prescribed. While second generation TKIs give faster and deeper responses, their impact on long-term survival remain to be determined. The choice of the TKI depends on CML risk score, priority for a deep response to allow a treatment-free remission protocol, age, presence of comorbid conditions, side effect profile, drug interactions, compliance concerns and price. Monitoring the response has to be made according the 2013 ELN criteria, and is based on the bone-marrow cytogenetic response during the first months and on the blood molecular response. Molecular follow-up is sufficient in patients with a complete cytogenetic response. For patients who fail frontline therapy, nilotinib, dasatinib, bosutinib and ponatinib are an option depending of the type of intolerance or resistance. T315I patients are only sensitive to ponatinib, which has to be carefully handled due to cardiovascular toxicity. Advanced phase diseases are more difficult to handle, with treatments including allogeneic stem cell transplantation, which is also an option for patients failing at least two TKIs. The possibility of treatment-free remission and pregnancy are also discussed. [less ▲]

This paper analyzes the implications of the Advanced Measurement Approach (AMA) for the assessment of operational risk. Through a clinical case study on a matrix of two selected business lines and two event types of a large financial institution, we develop a procedure that addresses the major issues faced by banks in the implementation of the AMA. For each cell, we calibrate two truncated distributions functions, one for “normal” losses and the other for the “extreme” losses. In addition, we propose a method to include external data in the framework. We then estimate the impact of operational risk management on bank profitability, through an adapted measure of RAROC. The results suggest that substantial savings can be achieved through active management techniques. [less ▲]

Two practical methods are proposed to measure the tortuosity of a porous or permeable material from its tomographic reconstruction. The first method is based on the direct measurement of the shortest distance between two points in the pores, and the second is based on the geodesic reconstruction of the pore or permeation space. Unlike the first method, the second can be directly applied to gray-tone tomograms, without the need of a segmentation step. The methods are illustrated with an electron tomogram of clay/plastic nanocomposite, an X-ray microtomogram of sandstone, and a series of model morphologies consisting of penetrable random spheres. For the latter series, the measured tortuosities compare very well with those derived independently from the theoretical effective diffusion coefficients [less ▲]

Pulmonary hypertension (PH) is defined by a sustained increase in mean pulmonary arterial pressure > 25 mmHg. Due to its widespread availability, echocardiography (ECHO) is used as the first-line imaging modality to detect pulmonary PH and assess right ventricular (RV) function in daily routine. As such, ECHO is the key examination to detect the presence of PH, to provide valuable prognostic information and to give an orientation to therapeutic strategies. In addition to detection and screening, ECHO also provides clues for the differential diagnosis of PH. The present document, based on a consensus of experts, provides practical recommendations for the use of ECHO in the evaluation of PH and of its consequences on the right ventricle. [less ▲]

A quantitative comparison of two 15 storey high framesdesigned to resist a 0.4g PGAhas been made: one frame corresponds to a standard design in which connections of diagonals are capacity designed to the diagonal sections and the other one uses dissipative connections at the diagonals ends. The structures are designed by a standard elastic procedure under reduced forces. Pushover analysis and non linear dynamic analyses are then performed to assess the real behavior and performance of the structures. The advantages of using dissipative connections are confirmed in a high rise flexible building. [less ▲]
