A conceptual model that simulates the formation and fate of odorous substances in branched collection systems is presented. The model predicts the activity of the relevant biomass phenotypes under aerobic, anoxic, and anaerobic conditions in force mains and gravity sewers. The formation and fate of individual, malodorous substances in the bulk water, biofilms, and sediments are modeled. The rel...

We consider the question: To what extend does the Weyl function (i.e., the abstract Dirichlet-to-Neumann map) see the same singularities as the resolvent of some restriction of the maximal operator. The proper, so-called detectable, subspace will be introduced and analyzed for particular examples, such as, Schrodinger operators, Hain–Lust operators, and (if time permits), the Friedrichs model o...

Nous voilà attablés à dix mains sur clavier pour écrire ce que rend possible notre écart la discipline sociologique, une même envie de bouger quelque chose dans l’étau des spécialités académiques, un « vouloir savoir » autrement nous partageons site web avec accent grave entrer matière du social, vie quotidienne, ordinaire. D’abord le récit tiré d’une longue enquête suivi courte observation ill...

Conventional structures of power inverter filters, required for grid coupling operation and to fulfill EMI requirements, lead to a system, which was difficult to control (due to its high system order) and problematic to realize due to unknown mains impedance behavior. In this paper, a matching filter topology is presented, which can overcome all these limitations. It is shown, that the optimal ...

this study empirically examines whether managers manipulate reported income through the timing of sales of long-lived assets and investments. several empirical implications of the income-smoothing and debt-equity hypothesis in the context of asset sales were tested. the findings are consistent with the timing of asset sales by managers so that the recognized accounting income from these sales s...

The k-set agreement problem is a coordination problem where each process is assumed to propose a value and each process that does not crash has to decide a value such that each decided value is a proposed value and at most k different values are decided. While it can always be solved in synchronous systems, k-set agreement has no solution in asynchronous send/receive message-passing systems whe...

Le traitement des hemorroides peut-etre dif­feren: selon l'intens,ite et la frequence de leur manifestations.  1. Crise hemorroidaire avec douleur, hemor­ragie et parfois peUt procidence, a la suite d'un repas, fatigue, etc ... sans precedent, est traiter par des moyennes medicaux apropries. 2. Les vrais hemorroides doivent etre traite soit par des methodes Sclerosantes, soit par des meth...
