Reconstructing initial data using observers: error analysis of the semi-discrete and fully discrete approximations

A new iterative algorithm for solving initial data inverse problems from partial observations has been recently proposed in Ramdani et al. (Automatica 46(10), 1616-1625, 2010 ). Based on the concept of observers (also called Luenberger observers), this algorithm covers a large class of abstract evolution PDE's. In this paper, we are concerned with the convergence analysis of this algorithm. More precisely, we provide a complete numerical analysis for semi-discrete (in space) and fully discrete approximations derived using finite elements in space and an implicit Euler method in time. The analysis is carried out for abstract Schrödinger and wave conservative systems with bounded observation (locally distributed)

Odonata as indicators of environmental impacts in rivers, case of wadi El-Kébir-East (northeastern Algeria)

This paper presents results of two monitoring programs carried out in two decades during April 1993-May 1994,and April 2015 May 2016 in the East Wadi of  El-Kébiri,  a protected area (PNEK) of eastern Numidia (northeastern Algeria). Monitoring was located in areas with different degrees of anthropogenic impacts.Selected environmental variables were recorded during the monitoring periods. . The Odonata fauna and biological indices were used to characterize development of the study area, after two decades and to assess the quality of the environment. The alteration of this river has resulted in a marked simplification of the original (1993-1994) odonatological fauna. Over the past two decades, odonatological species richness has decreased from 14 to 7 species inventoried during the 1993 and 2015 seasons. The phenology of adult was extended until early December 2015, possibly as a result of global warming. Odonata are identified as useful as indicators of environmental change in the monitored river systems. The majority of species such as the Gomphidae are not tolerant of increased contamination and changes in structure of the river. Only some species such as Lestes vridis, Platycnemis subdilatata, Ischnura graellsii and Ceriagrion tenellum, appear to be adapted to changed conditions and became dominant in heavily disturbed sites. The species disappeared from these sites are clearly associated with good water quality and less disturbance, which highlights the importance of the conservation of the habitats of freshwater and regular monitorin

Chemical Composition and Antioxidant Activity of seeds oils and fruit juice of Opuntia Ficus Indica and Opuntia Dillenii from Morocco

peer reviewedThis study provides basic information on the mineral composition of the seeds and antioxidant activity in seeds oils and fruit juices of cactus belonging to two species Opuntia ficus indica and Opuntia dillenii, from Morocco (Oujda), in order to evaluate the nutritional value of the Opuntia extracts. Minerals determined from dry seeds of Opuntia ficus indica and Opuntia dillenii were: calcium 480.93 and 408.28; phosphorus 1417.59 and 970.15; potassium 304.51 and 201.96; magnesium: 316.59 and 240.30; sodium: 48.33 and 18.18; zinc: 70.77 and 78.26 mg/100g respectively. The main fatty acids of Opuntia ficus indica and Opuntia dillenii seed oil were respectively: linoleic acid: 58.79 and 79.83%, Palmitic acid: 11.18 and 13.52%. The antioxidant activity of Opuntia ficus indica and Opuntia dillenii seed oils and fruit juices were assessed by means of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay and ascorbic acid test. The results showed that the antioxidant activities of Opuntia ficus indica and Opuntia dillenii seed oil (IC50 = 19.79 ± 0.023 and 27.21 ± 0.075 μL/mL) are higher than that of the reference ascorbic acid (IC50 = 16.56 ± 0.019 μg/mL). However, the Opuntia dillenii juice presents antioxidant activity more important than this of Opuntia seed oil and ascorbic acid. It possessed strong antioxidant activity (IC50 = 8.18 μL/mL). The antioxidant activity of the seed oil and juice were also found to be concentration-dependent

Air quality in the metropolitan area of Sidi Bel Abbes (Algeria) through the lichens species as bio-indicators

The air quality in towns and cities is increasingly deteriorating as human activities increase but no actions have been taken in Algeria to limit air pollution. There are no regulations for controlling pollutant emissions and no specialist treatment center for treating diseases and allergies caused by  air pollution. To access urban air quality lichens species were used for bio-monitoring   12 stations spread across Sidi Bel Abbés city (Western  Algeria). The use of living organisms, in this case lichens, for evaluating the quality of air is a preferred method.  European lichenologists developed a new environmental quality assessment protocol using mapping lichen diversity and  lichens are very often used as bio- accumulators. The selected species are generally those growing on tree trunks, and having a broad geographic distribution. The lichen species most often used are thallus foliaceus or fruticose forms such as Parmelia caperata, P. sulcata, Hypogymnia physodes, Xanthoria parietina, Evernia prunastri, Pseudevernia furfuracea. These lichens species have large adsorption surfaces for major pollutants.  In this work we evaluate the air quality by applying lichen index based on German environmental engineers to map air pollution  in the city of Sidi Bel Abbes

Discrete-State Abstractions of Nonlinear Systems Using Multi-resolution Quantizer

Abstract. This paper proposes a design method for discrete abstrac-tions of nonlinear systems using multi-resolution quantizer, which is ca-pable of handling state dependent approximation precision requirements. To this aim, we extend the notion of quantizer embedding, which has been proposed by the authors ’ previous works as a transformation from continuous-state systems to discrete-state systems, to a multi-resolution setting. Then, we propose a computational method that analyzes how a locally generated quantization error is propagated through the state space. Based on this method, we present an algorithm that generates a multi-resolution quantizer with a specified error precision by finite refine-ments. Discrete abstractions produced by the proposed method exhibit non-uniform distribution of discrete states and inputs.

Exact Controllability of the Time Discrete Wave Equation: A Multiplier Approach

In this paper we summarize our recent results on the exact boundary controllability of a trapezoidal time discrete wave equation in a bounded domain. It is shown that the projection of the solution in an appropriate space in which the high frequencies have been filtered is exactly controllable with uniformly bounded controls (with respect to the time-step). By classical duality arguments, the problem is reduced to a boundary observability inequality for a time-discrete wave equation. Using multiplier techniques the uniform observability property is proved in a class of filtered initial data. The optimality of the filtering parameter is also analyzed

cAMP-Signalling Regulates Gametocyte-Infected Erythrocyte Deformability Required for Malaria Parasite Transmission.

Blocking Plasmodium falciparum transmission to mosquitoes has been designated a strategic objective in the global agenda of malaria elimination. Transmission is ensured by gametocyte-infected erythrocytes (GIE) that sequester in the bone marrow and at maturation are released into peripheral blood from where they are taken up during a mosquito blood meal. Release into the blood circulation is accompanied by an increase in GIE deformability that allows them to pass through the spleen. Here, we used a microsphere matrix to mimic splenic filtration and investigated the role of cAMP-signalling in regulating GIE deformability. We demonstrated that mature GIE deformability is dependent on reduced cAMP-signalling and on increased phosphodiesterase expression in stage V gametocytes, and that parasite cAMP-dependent kinase activity contributes to the stiffness of immature gametocytes. Importantly, pharmacological agents that raise cAMP levels in transmissible stage V gametocytes render them less deformable and hence less likely to circulate through the spleen. Therefore, phosphodiesterase inhibitors that raise cAMP levels in P. falciparum infected erythrocytes, such as sildenafil, represent new candidate drugs to block transmission of malaria parasites
