In this paper, the existing lumped circuit model for Through-Silicon-Via (TSV) structure embedded in Lightly-doped silicon substrate is reviewed and improved. A new lumped circuit model for TSV structure in heavily-doped silicon substrate is proposed. The underlying physics associated with the proposed lumped elements in the circuit topology is discussed and their values are found by data fitti...

We analyse the fi nancial performance of small German hospitals based on balance sheet data of about 1,000 hospitals in 2007. Measures of fi nancial performance are the earnings before interest, tax, depreciation, and amortisation (EBITDA) and the probability of default (PD). We fi nd that, on average, small hospitals have more fi nancial diffi culties than large ones. However, there is conside...

We analyze the investment decision of a firm that has an option to complete an investment project either in one lump or in two smaller parts at distinct points in time. The firm faces a trade-off between the cost savings that arise when the project is completed at once and the additional flexibility that arises when the firm is able to respond to resolving uncertainty by choosing optimal timing...

Hydroxylamine nitrate (HAN) is an important member of the hydroxylamine compound family with applications that include equipment decontamination in the nuclear industry and aqueous or solid propellants. Due to its instability and autocatalytic behavior, HAN has been involved in several incidents at the Hanford and Savannah River Site (SRS) [Technical Report on Hydroxylamine Nitrate, US Departme...

This review attempts to provide an updated compilation of studies reported in the literature pertaining to reactors containing lipases in immobilized forms, in a way that helps the reader direct a bibliographic search and develop an integrated perspective of the subject. Highlights are given to industrial applications of lipases (including control and economic considerations), as well as to met...

This paper presents the lumped parameters model of an internal gear crescent pump with relief valve, able to estimate the steady-state flow-pressure characteristic and the pressure ripple. The approach is based on the identification of three variable control volumes regardless of the number of gear teeth. The model has been implemented in the commercial environment LMS Amesim with the developme...

Numerous electrical analog models of the circulatory system have been proposed. However, conventional models are either too simple, focusing exclusively on heart function, or overly complex, characterizing arteries in excessive detail. The vessel beds, which comprise arteries, capillaries and veins, are well known to be responsible for most of the pressure drop in blood pressure and to dominate...
