    Nous présentons dans ce travail les origines physiques des sources indépendantes de bruit dans le CPA (préamplificateur de charge), puis avec à l’aide du PS (circuit de filtrage) améliorer le S/B (rapport signal sur bruit). Dans la première partie, nous sommes intéressés aux équations mathématiques permettant d’exprimer les différentes sources de bruit. La seconde partie de ce travail s’étend sur l’évaluation du bruit en termes de l’ENC (Equivalent Noise Charge). Par la suite, les études et simulations vont être effectuées sur une technologie standard AMS CMOS 0.35µm et vont montrer que la miniaturisation est un atout. Aussi la valeur de l’ENC total est essentiellement dominée par l’expression du bruit thermique du transistor d’entrée et cette derniere peut etre optimisée au détriment de la consommation en jouant sur ID. La valeur du courant de drain et le dimensionnement du transistor d’entrée sont décisifs pour le bruit.Mots-clés : bruit, préamplificateur de charge, filtre CR-(RC) n, transistor CMOS, MatLab.Analysis of noise in CMOS charge sensitive preamplifier with PS circuit We present in this work the physical origins of independent noise sources in the front end circuit based on CMOS devices. The PS (Pulse shaper) added to CSA (charge sensitive preamplifier) improves the quality of SNR (Signal-to-Noise Ratio). In the first part, we are interested in the mathematic equations to express the different noise sources. The second part of this work has focusing on its evaluation in terms of ENC (Equivalent Noise Charge). Studies and simulations are performed for a 0.35µm CMOS on standard technology AMS and shown that the design circuit can reduce the noise level of the CSA. ENC is dominated by the thermal noise of an input transistor MOS and the thermal noise of the feedback resistor Rf. We show several aspects of the noise optimization of the CSA regarding the optimum transistor width W and the sensitivity of the ENC to this width.Keywords : noise, charge preamplifier, filter CR-(RC) n, transistor CMOS, MatLab

    EFFECTS OF THE REUSE OF UNTREATED WATER FROM THE AVO’O RIVER (CAMEROON) CONTAMINATED BY FECAL SLUDGE FOR THE GROWTH OF SOLANUM NIGRUM L.

    Get PDF
    Objective: The main objective of this research was to evaluate the growth parameters and sanitary quality of Solanum nigrum L. irrigated with polluted water from Avo’o river in Nomayos. Methods: Faecal sludge, water from Avo’o River and Solanum nigrum L., were analysed with respect to microbiological and parasitological parameters. Four points (S0: Control site, located in Mbankomo at 3 km away from faecal sludge discharge area; S1: located at 810 m before the faecal sludge discharge area; S2: located at 100 m away from the faecal sludge discharge area; and S3: located at 350 m after the faecal sludge discharge area) were considered for sampling events. For faecal indicator (FC: Faecal coliforms and FS: Faecal Streptococci), the membrane filtration method was used. Helminthes eggs were determined using the method of Bailenger, modified by Rodier. The growth parameters of S. nigrum L., measured in different site mentioned above, were plant height, number, length and width of fresh leaves. Results: High concentration of FC (6857 ± 5180) and FS (2500 ± 1876 CFU/100 ml), as well as helminths eggs (273 ± 186 eggs/L) were obtained in Avo’o water samples. The strong correlations (r=0.9) clearly show that the waters of the Avo’o stream influence the growth of S. nigrum L. Conclusion: Despite the best growth of Solanum Nigrum L. irrigated with water from Avo’o River, high concentration of parasites was obtained on their leaves (43 eggs/100 g) highlight the necessity of a better management of faecal sludge in this city

    Neutrino masses and mixings in the baryon triality constrained minimal supersymmetric standard model

    Full text link
    We discuss how the experimental neutrino oscillation data can be realized in the framework of the baryon triality (B3B_3) constrained supersymmetric Standard Model (cSSM). We show how to obtain phenomenologically viable solutions, which are compatible with the recent WMAP observations. We present results for the hierarchical, inverted and degenerate cases which illustrate the possible size and structure of the lepton number violating couplings. We work with a new, as yet unpublished version of SOFTSUSY, where we implemented full one--loop neutrino masses. Finally, we shortly discuss some phenomenological implications at the LHC.Comment: 25 pages, 17 figure

    The Effects of Light and Nitrate Levels on the Relationship Between Nitrate Reductase Activity and (NO3-)-N-15 Uptake: Field Observations in the East China Sea

    Get PDF
    Nitrate reductase activity (NRA) and 15NO3- uptake (NU) were determined in the East China Sea and the adjoining Kuroshio in May 1996, at six stations covering a range of hydrographic conditions: the nutrient-rich and fresher plume of Changjiang Diluted Water along the Chinese coast, the nutrient-rich upwelling Kuroshio Subsurface Water at the shelf edge northeast of Taiwan, the oligotrophic Kuroshio Surface Water and the mixing zones among these water masses on the shelf. The values of NRA in the surface mixed layer ranged between 16 and 0.1 nM-N h-1, whereas those of NU ranged between 37 and 1 nM-N h-1. Higher NRA and NU were found in the frontal zone between the coastal and shelf waters and in the upwelling zone, whereas the lowest values were found in the surface Kuroshio. The NRA/Chl a ratio increased linearly with increasing NU/primary production ratio in the sequence: Kuroshio \u3c coastal plume \u3c upwelling zone and mixing zones in the shelf. This is probably a reflection of the varying nutrient condition and the relative importance of NU in sustaining the biomass in these regions. In nitrate- and light-replete waters, the average NU/NRA was 1.0 +/- 0.3. NRA was linearly related to NU so that NU = 1.08 (+/- 0.07)NRA (r(2) = 0.79). Thus, NRA may be used for estimating NU in these waters. In nitrate deficient and light-replete waters, the average NU/NRA was 4 +/- 4. These high and variable values of NU/NRA might have been caused by an over-estimation of NU as a result of the stimulatory effect of the added 15NO3-N on phytoplankton growth. Thus, NRA may be a more reliable indicator of the rate of NO3- uptake in oligotrophic waters. In nitrate-replete and light-deficient waters, NU did not correlate well with NRA. The average NU/NRA was 0.7 +/- 0.7. These low and variable values of NU/NRA suggest a possible decoupling between NRA and NU. By using the relationship between NU and NRA in nitrate- and light-replete waters and the depth-integrated inventory of NRA in the photic zone at each station, NU in oligotrophic waters, the coastal plume, upwelling waters and shelf waters can be estimated to be 0.45, 1.55, 3.12, and 3.59 mg-N m-2 h-1 respectively. These values fall well within the range of previously reported values in similar types of water

    Charge asymmetry ratio as a probe of quark flavour couplings of resonant particles at the LHC

    Full text link
    We show how a precise knowledge of parton distribution functions, in particular those of the u and d quarks, can be used to constrain a certain class of New Physics models in which new heavy charged resonances couple to quarks and leptons. We illustrate the method by considering a left-right symmetric model with a W' from a SU(2)_R gauge sector produced in quark-antiquark annihilation and decaying into a charged lepton and a heavy Majorana neutrino. We discuss a number of quark and lepton mixing scenarios, and simulate both signals and backgrounds in order to determine the size of the expected charge asymmetry. We show that various quark-W' mixing scenarios can indeed be constrained by charge asymmetry measurements at the LHC, particularly at 14 TeV centre of mass energy.Comment: 14 pages, 3 figure

    A robust abnormal behavior detection method using convolutional neural network

    Get PDF
    A behavior is considered abnormal when it is seen as unusual under certain contexts. The definition for abnormal behavior varies depending on situations. For example, people running in a field is considered normal but is deemed abnormal if it takes place in a mall. Similarly, loitering in the alleys, fighting or pushing each other in public areas are considered abnormal under specific circumstances. Abnormal behavior detection is crucial due to the increasing crime rate in the society. If an abnormal behavior can be detected earlier, tragedies can be avoided. In recent years, deep learning has been widely applied in the computer vision field and has acquired great success for human detection. In particular, Convolutional Neural Network (CNN) has shown to have achieved state-of-the-art performance in human detection. In this paper, a CNN-based abnormal behavior detection method is presented. The proposed approach automatically learns the most discriminative characteristics pertaining to human behavior from a large pool of videos containing normal and abnormal behaviors. Since the interpretation for abnormal behavior varies across contexts, extensive experiments have been carried out to assess various conditions and scopes including crowd and single person behavior detection and recognition. The proposed method represents an end-to-end solution to deal with abnormal behavior under different conditions including variations in background, number of subjects (individual, two persons or crowd), and a range of diverse unusual human activities. Experiments on five benchmark datasets validate the performance of the proposed approach

    Same-sign W pair production as a probe of double parton scattering at the LHC

    Full text link
    We study the production of same-sign W boson pairs at the LHC in double parton interactions. Compared with simple factorised double parton distributions (dPDFs), we show that the recently developed dPDFs, GS09, lead to non-trivial kinematic correlations between the W bosons. A numerical study of the prospects for observing this process using same-sign dilepton signatures, including same-sign WWjj, di-boson and heavy flavour backgrounds, at 14 TeV centre-of-mass energy is then performed. It is shown that a small excess of same-sign dilepton events from double parton scattering over a background dominated by single scattering WZ(gamma*) production could be observed at the LHC.Comment: 14 pages, 8 figures.

    Sparticle Spectra and LHC Signatures for Large Volume String Compactifications

    Full text link
    We study the supersymmetric particle spectra and LHC collider observables for the large-volume string models with a fundamental scale of 10^{11} GeV that arise in moduli-fixed string compactifications with branes and fluxes. The presence of magnetic fluxes on the brane world volume, required for chirality, perturb the soft terms away from those previously computed in the dilute-flux limit. We use the difference in high-scale gauge couplings to estimate the magnitude of this perturbation and study the potential effects of the magnetic fluxes by generating many random spectra with the soft terms perturbed around the dilute flux limit. Even with a 40% variation in the high-scale soft terms the low-energy spectra take a clear and predictive form. The resulting spectra are broadly similar to those arising on the SPS1a slope, but more degenerate. In their minimal version the models predict the ratios of gaugino masses to be M_1 : M_2 : M_3=(1.5 - 2) : 2 : 6, different to both mSUGRA and mirage mediation. Among the scalars, the squarks tend to be lighter and the sleptons heavier than for comparable mSUGRA models. We generate 10 fb^{-1} of sample LHC data for the random spectra in order to study the range of collider phenomenology that can occur. We perform a detailed mass reconstruction on one example large-volume string model spectrum. 100 fb^{-1} of integrated luminosity is sufficient to discriminate the model from mSUGRA and aspects of the sparticle spectrum can be accurately reconstructed.Comment: 42 pages, 21 figures.
