Photoplethysmography (PPG) is a widely emerging method to assess vascular health in humans. The origins of the signal of reflective PPG on peripheral arteries have not been thoroughly investigated. We aimed to identify and quantify the optical and biomecha ...
This thesis develops three models that study the motivation of various agents to take on debt,
and the impact that excessive financial leverage can have on social welfare.
In the chapter "Short-term Bank Leverage and the Value of Liquid Reserves", the ince ...
We consider a portfolio of products in which each product probabilistically transitions through various life cycle stages. The evolution through these life cycle stages is impacted by both marketing support and product launch decisions, which are bound by ...
We propose a model that jointly determines the capital structure and investment decisions taking business cycle and debt maturity into account. It endogenously determines the triggers of investment/disinvestment and default, which depend on the state of th ...
We propose a model of a firm's reversible investment decision with macroeconomic conditions based on optimal switching of a diffusion regime. The switching costs and the cash flow generated from the firm depend on a business cycle alternating via a Markov ...
Arterial tree hemodynamics can be simulated by means of several models of different level of complexity, depending on the outputs of interest and the desired degree of accuracy. In this work, several numerical comparisons of geometrical multiscale models a ...
Supply chain management is widely accepted as a means for companies to gain competitive advantage. While product and information flows have been widely covered in the literature, relatively little attention has been paid to the management of a supply chain ...
Financial flows are often treated in a fragmented and disconnected way from the physical product flow. Managers take decisions from an operational point of view concerning inventory, service level or capacity needs. The implementation of such decisions inf ...
Closed-loop supply chains (CLSC) consider all of the activities in the lifecycle of a product from design to end-of-life operation. These chains encompass, in addition to the traditional forward flow of products to customers, the acquisition and return flo ...
Regions of positive slope in the pressure-discharge characteristics can result in a reduction or even lack of damping of system instabilities. They are therefore one of the major concerns in design and operation of centrifugal pumps as they are limiting th ...
