We discuss passive nonlinear energy pumping from a linear (main) mechanical structure to a weakly coupled, local, passive nonlinear energy sink (NES). We show that the NES can be designed to effectively absorb vibrational energy from the main structure in a one-way, irreversible fashion. We demonstrate the occurrence of pumping cascades, where an appropriately designed NES passively extracts energy sequentially from a number of modes of the main (linear) structure, interacting individually with each mode before moving to the next. Experimental results confirm our theoretical findings. The applications of the nonlinear energy pumping phenomenon to the problem of vibration and shock isolation will be discussed [less ▲]

Hypothesis / aims of study The aim of this study was to prospectively evaluate the efficacy of the TVT-O inside-out procedure for the treatment of female stress urinary incontinence (SUI). Study design, materials and methods From March 2003 through September 2003, 53 patients with clinical evidence of SUI participated in this prospective clinical trial. Preoperative evaluation included complete history, physical examination, multichannel urodynamics, urine analysis, and cystoscopy. None of the patients presented the following exclusion criteria: post-void residual volume (PVR) ≥ 100 cc, detrusor overactivity or acontractility, contraindication to anesthesia, pregnancy, neurological pathology, or active urinary or vaginal infection. All patients met the following inclusion criteria: age > 25 and < 85 years, clinically demonstrated SUI, positive Ulmsten test, and maximum cystometric capacity ≥ 300 mL. In all patients, a sub-urethral tape (Gynecare®) was inserted by one single surgeon via an inside-out transobturator approach (TVT-O), as previously described (1). Evaluation of SUI, urgency/urge incontinence, daytime urinary frequency/nocturia, and lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction/retention was carried out using the Measurement of Urinary Handicap scale questionnaire (2). The importance of urinary incontinence was assessed with a visual analog scale graded from 0 to 10. Quality of life (QoL) assessment was performed using the validated Ditrovie self-administered questionnaire. Outpatient follow-up was perfomed at 1 and 6 months, and every 6 months thereafter. Follow-up evaluation included physical examination with a stress test, uroflowmetry, PVR, and symptom, visual analog, and QoL scales scoring. Cure was defined as no leakage based on both symptom scale scoring and physical examination. Improvement was defined as at least a 50% decrease in symptoms based on the questionnaire’s evaluation. Chart review was conducted by a physician not associated with the surgical procedure. The specific protocol used in this study was approved by the Medical Ethics committee of our Institution. All patients had given their written informed consent. Methods, defintions,and units conform to the standards recommended by the ICS. Results Mean age of the patients was 61.2 years (36 to 80). Of the 53 patients, 20 had undergone previous pelvic surgery. Forty-eight patients suffered from SUI. Five patients did not complain of SUI but had clinical evidence of SUI after reduction of pelvic organ prolapse (POP) during vaginal examination. The TVT-O procedure was associated with POP cure (performed before TVT-O) in 12 patients. Maximal urethral closure pressure was < 30 cm H20 in 6 patients. Follow-up time was ≥ 6 months in all women (max = 12.5; mean = 8). A total of 33 and 20 women received spinal and general anesthesia, respectively. Intraoperative blood loss was < 100 cc in all cases. No vaginal wall, urethral, or bladder perforation was encountered. No hematoma, neurological complication, fistula, vaginal or urethral erosion, or tape rejection was observed. Some patients reported pain symptoms, directly after the procedure, mainly located in the thigh regions (either uni- or bilaterally). Pain was always mild, never requiring opioid antalgics. No patient complained of persistent pain; indeed, pain had completely vanished within the first post-operative month in all cases. At the latest follow-up visit, PVR was < 100 cc and max flow rate was ≥ 10 mL/sec in 49 (92.4%) and 39 (73.6%) patients, respectively. One patient underwent an immediate tape release procedure for complete retention 2 days after TVT-O. Thereafter, the patient had no PVR and was completely dry. The tape was sectioned in 2 patients for chronic retention and/or urgency associated with bladder outlet obstruction, 4 and 7 months after the operation. Based on the SUI questionnaire evaluation and physical examination, 50 (94.3%) patients were cured. SUI symptoms had improved in 1 patient and had not changed in another. One patient with POP not complaining of SUI preoperatively (but with clinically demonstrated SUI following POP reduction) developed SUI after POP cure associated with TVT-O. Analysis of the urgency questionnaire’s results revealed that among the 53 patients, 32 did not complain of any urgency before the operation. Of these 32 patients, 3 patients developed de novo urgency, with one of them requiring tape sectioning because of obstruction-associated urge incontinence. Among the 21 patients with preoperative urge symptoms, 15 of them reported disappearance of urgency after the procedure. Urge symptoms were unchanged in the remaining 6 patients. Daytime frequency/nocturia symptoms scale scoring showed that 4 patients had a worsening of these symptoms while all other patients were either improved or unchanged. LUTS suggestive of bladder outlet obstruction/retention appeared or worsened in 3 patients, amongst which the 2 patients who required tape sectioning. These symptoms were unchanged or decreased (mainly in patients with associated POP cure) in all other patients. Analysis of the urinary incontinence visual analog and QoL scale scores demonstrated that the majority of patients reported disappearance of urinary leakage together with significant improvement of their QoL (Figures 1 and 2). Interpretation of results As already suggested by the results of a recent feasibility study (1), TVT-O appears to be associated with a minimal risk of peri-operative complications. Indeed, in our present prospective study, no injury to the bladder, vagina, or urethra was encountered and we have not observed any vascular, digestive or neurological complication. Our data suggest that TVT-O is associated with high objective and subjective SUI cure rates and a low incidence of post-operative complications. Longer follow-up times are required to determine the long-term efficacy of TVT-O. Concluding message The short term results of this prospective study suggest that TVT-O is a safe and efficient surgical procedure for the treatment of female SUI. References 1.

Numerical crack propagation schemes were augmented in an elegant manner by the X-FEM method applied to fracture mechanics. The use of special tip enrichment functions, as well as a discontinuous function along the sides of the crack allows one to do a complete crack analysis virtually without modifying the underlying mesh, which is of an evident industrial interest. The conventional approach for crack tip enrichment (described in [2,3]) is that only a specific layer of elements are enriched around the crack tip. We show that this “topological” approach does not yield an increase of the order of the asymptotic convergence rate when compared to unenriched finite elements, as when the crack is part of the mesh. It rather modifies the proportionality factor of the asymptotic convergence rate. In this study, we propose another enrichment scheme which yields a convergence rate that appears to be close to that of regular finite elements used when the solution field does not show singularities. The enriched basis in X-FEM degrades the rigidity and mass matrices condition numbers (the mass matrix typically appears in case of time dependent problems such as wave propagation in cracked bodies). To recover the condition number of non enriched matrices, we introduce a preconditioning strategy which acts block-wise on the set of enriched degrees of freedom associated to each node. This strategy uses a local (nodal) Cholesky based decomposition. Another issue is brought by the integration scheme used to build the matrices. The nature of the asymptotic functions are such that any Gauss-Legendre based integration scheme will only poorly converge with respect of the order of the quadrature. We propose a modified integration scheme to handle that issue. We apply the new technique developed to the estimation of stress intensity factors along the crack front of 3D cracks and use these SIFs for crack propagation using a Paris type fatigue law.

Glucosinolates are a class of ca. 120 secondary plant metabolites generally found in Brassicaceae. These compounds have a similar structure characterised by a common part containing a beta thioglucose coupled with a sulfonated oxim group and by a variable organic side chain constituted with alkyl, alcenyl, hydroxy-alcenyl, aryl, indolyl, sulfinyl, sulfonyl or thio residues. Present in high or low level (00 varieties) in rapeseed/canola seeds and in rapeseed/canola meals, these molecules are easily broken down during animal digestion, leading to compounds with detrimental and antinutritional characteristics. They are known to interfere with the thyroid and to damage vital organs (Fenwick et al., 1983). [less ▲]

This paper models the sea bottom evolution. This model is built up on three main parts. The first one describes the wave propagation, taking simultaneously into account the refraction, the diffraction and the reflection but also the energy dissipation caused by wave breaking. This model is solved by the numerical method of the finite volumes, using an iterative resolution (the GMRES method). Several validations of this model have been carried out on many examples such as harbors of various geometries and depths, beaches,… The wave induced currents are computed in the second part based on the concept of the radiation stresses describing the excess of the flux momentum caused by the waves. A model based on the complete Navier-Stokes equations integrated on the depth and associated with appropriated forcing and friction terms is used. This model is computed as an update of WOLF software (HACH, ULg) and is applied to some examples such as beaches with or without coastal structures. Finally, the third part is about the sediment transport. It exhibits the topographic modifications of the coastal sea bottom caused by the waves and their currents. A loop execution of these three models ends this work. It gives us an operational tool to describe the topographic evolution of the coastal areas caused by the incident waves, the induced currents and then the resulting sediment transport, fulfilling the objectives of this paper.

Satellite images are very useful for many applications in oceanography and other environmental sciences. They offer a great coverage both in time and space, not attained by in situ measurements. Clouds are responsible for missing data on images provided by receptors working in the visible and IR range receptors. In some seasons the cloud coverage can reach an important percentage. Many data analysis techniques do not need a total coverage, although it is always desirable. Some applications, such as Empirical Orthogonal Function (EOF) analysis, or wavelet decomposition need a complete set of data, and a technique for recovering these missing data is indispensable. In this work we present DINEOF (Data INterpolating Empirical Orthogonal Functions), a method for the reconstruction of satellite data, based on an EOF decomposition. DINEOF reconstructs the missing data from an optimal set of EOFs. The optimal number of EOFs is determined by cross-validation. This method has shown to obtain robust results. DINEOF has been applied to a series of 105 AVHRR SST images of the Adriatic Sea, in a period ranging from May to October 1995. The mean cloud coverage of this data set is 52%. The error obtained by the cross-validation is of 0.6°C, and a total of 10 EOFs were necessary to reconstruct the data. A comparison with in situ data obtained form the MEDAR/Medatlas database is made. A total of 452 stations are examined. The RMS error between MEDAR/Medatlas and the reconstructed data is of 0.95°C. The error between MEDAR/Medatlas data and the points that are not missing in the Adriatic data set is of 0.67°C, which can be considered as the inherent error between the in situ and remote sensed data sets.

This paper presents the numerical studies lead by the Laboratory of Applied Hydrodynamics and Hydraulic Constructions of the University of Liège (HACH) for the rehabilitation of the 21-meter high Nisramont dam in Belgium. After determination of the up-to-date 1000-year return flood using the hydrological runoff model WOLFHYDRO on the global 74,000 ha watershed real topography coupled with statistical analyzes, and after validation on the existing situation and for extreme observed events, the 2D finite volume multiblock flow solver WOLF2D has been applied to the design of the new stilling basin and to the bottom outlet rehabilitation impact study. The multiblock solver possibilities allow mesh refinement close to interesting areas, such as dam spillway and stilling pool, without leading to prohibitive CPU times, while suitable shallow water equations formulation allows the computation of the flows on the strongly vertically curved bottom of the spillway. In the described simulation, 270,000 structured finite volumes, from .25 to 1 meters long, are used to simulate as a whole the flows in the upstream reservoir, dam, spillway, stilling basin and downstream river, this on a real topography.

The paper presents some applications of a local second gradient theory used to describe the mechanical behavior of a continua. This theory has been developed in order to avoid some well known drawbacks of classical theories, when softening and/or localization occur in a computation. This theory is extended and then applied in a hydromechanical coupled problem, in the case of fully saturated geomaterials. The corresponding finite element method taking into account the geometrical non linearities is detailed. Preliminary results using the finite element code developed in this context are then discussed and allow to study post localization behavior. [less ▲]

In the last years, Europe was subject to catastrophic inundations. At the same time, computer's capacity are increasing such as bidimensional simulations can be applied to real cases. Two compementary theoretical and numerical models are presented and discussed in the present paper: the diffusive approximation and the complete shallow-water approach. An original refinement of meshes is also presented to increase the convergence speed to a steady solution. Numerous comparisons between models and methods of resolution are described. Finally, an example of determination of the flood extension on a natural river is illustrated. [less ▲]

Radiometric dates, typology and sedimentology suggest an autochthonous origin for the Gravettian culture in the Middle Danube. Its complex development is marked by tool specialisation, a demographic increase and an apparent sedentism. Subsequently, this key region spread to the east or the west by autonomous migratory movements during each phase (Bayacian, Kostenkian). The form of religiosity that is finally associated with this culture constitutes the first artistic creation evidencing a matriarchal system. Through the artistic forms, this belief system is also modified through time and across space: it is characterised as well by recognisable artistic “styles”. The broad Gravettian entity, in its distribution and the finesse of its adaptation, was a product of continental Europe, for which it constitutes the origin of later cultures and populations. At the same time, its plastic expressions seem to result in an Aurignacian acculturation, and its anatomy a blend of Neandertals with incoming modern humans. Curiously, recent phases are limited to the eastern Danube Basin. The Pleniglacial B seems to have interrupted western contacts, where the Magdalenians would soon appear, until Moravia. From then on, Europe as a whole would no longer be unified. In consequence, new approaches to the study of the Danubian Gravettian should be oriented towards the eastern plains, Moldavia and The Crimea. [less ▲]

A general approach to real-time transient stability control is described, yielding various complementary techniques: pure preventive, open loop emergency, and closed loop emergency controls. The organization of the resulting control schemes is then revisited in order to make it able to cover static and voltage security, in addition to transient stability. Distinct approaches for preventive and emergency operating conditions are advocated. [less ▲]

Four complementary and independent methods are used to characterize nanotube samples: (i) TEM observation coupled with image analysis, (ii) nitrogen and krypton adsorption isotherm analysis, (iii) thermogravimetry and (iv) wide angle X-ray scattering. The methodology is discussed on the basis of two multi-walled carbon nanotube samples produced by the CCVD technique with very different reaction rates. It is shown that the total amount of deposited carbon is larger for the sample produced at the higher rate, that the fraction of nanotubes in the deposited carbon does not seem to be significantly different, but that the crystallinity of the nanotubes wall is larger for the sample produced at the lowest reaction rate.

The quasi-3D flow solver WOLF has been developed at the University of Liege for almost a decade. It has been used to carry out the simulation of silting processes in large reservoirs and to predict the efficiency of flushing operations. Besides briefly depicting the mathematical and numerical model, the present paper demonstrates its applicability on the case of a large hydropower project in India. The silting process of the reservoir has been simulated by means of the quasi-3D flow model with a quasi-steady approach. For simulating flushing events, both the topography changes and their interactions with the flow have been carefully handled in a strongly coupled approach. This narrow coupling has required the development of a suitable upwind numerical scheme. Results are presented with 2D- and 3D-views, completed by cross-sections and curves of the variation of key variables. The numerous observations based on those results lead to a global assessment of the silting mechanism and of the flushing efficiency. [less ▲]

In this paper we consider an electricity market in which not only the power producers but also the transmission owners can submit a bid. The market is cleared at each stage by minimizing the sum of the production prices and the transmission prices. A model of the strategic behavior is formulated for the different agents of the system. This strategic behavior modelling leads to a market dynamics that can be used to determine the different payoffs of the agents over a temporal horizon. Simulations are carried out for several configurations of this two node power system. The influence of the transfer capacity and the market structure on the payoffs of the different agents is discussed. [less ▲]
