Power supply units (PSUs) with an equally shared load current are widely employed for data processing equipment like servers due to their advantages such as easy extension of power processing capability and simple thermal management. This paper presents a method to improve light-load efficiency by reducing load-independent losses such as capacitive turn-on and core losses and reduce the THD of ...

We use a Principal-Agent framework to evaluate the economic impacts of imposing a tax on insurance payment in presence of moral hazard using a Gamma conditional distribution of losses. Our results show that any tax paid by the insured would the lower his effort to prevent loss, hence increasing insurance payments and decreasing pro ts. This result is reinforced as the insured becomes more risk ...

In this paper, we introduce the new generation 3300V HiPak2 IGBT module (130x190)mm employing the recently developed TSPT+ IGBT with Enhanced Trench MOS technology and Field Charge Extraction (FCE) diode. The new chip-set enables IGBT modules with improved electrical performance in terms of low losses, good controllability, high robustness and soft diode recovery. Due to the lower losses and th...

We demonstrate that, in the classical non-stochastic regret minimization problem with d decisions, gains and losses to be respectively maximized or minimized are fundamentally different. Indeed, by considering the additional sparsity assumption (at each stage, at most s decisions incur a nonzero outcome), we derive optimal regret bounds of different orders. Specifically, with gains, we obtain a...

In this paper we propose an analytical model of a resilient, tree-based end-node multicast streaming architecture that employs path diversity and forward error correction for improved resilience to node churns and packet losses. Using the model and via simulations we study the performance of this architecture in the presence of packet losses and dynamic node behavior. We show that the overlay c...

Recent research has focussed on the problems associated with TCP performance in the presence of wireless links and ways to improve its performance. We present an extension to TCP Santa Cruz which improves TCP performance over lossy wireless links. TCP has no mechanism to differentiate random losses on the wireless link from congestion, and therefore treats all losses as congestive. We present a...

The objective of this paper is to provide a comparative assessment of the consequences of worker displacement in France and the United-States. I estimate wage losses of displaced workers in the two countries and examine the relative contribution of two important sources of post-displacement wage adjustments. The first one relates to the loss of seniority-accumulated firmspecific earnings potent...

The weights of single mealworms were continuously recorded at 20 degrees C during exposure to periods of constant humidity and to abrupt changes in atmospheric vapour pressure. Two exchange stages were recognized in each animal. Weight changes were either limited to slow losses, suggesting transpiration through the external cuticle, or showed more rapid humidity-dependent gains as well as losse...

New high speed serial interfaces provide a major benefit to designers looking to provide greater data bandwidth across the backplanes or when interfacing chip to chip. However high speed signaling techniques suffer from a number of issues not seen at normal digital signaling levels. One key problem, which applies to all transmission mediums, but particularly related to PCB layout, are frequency...
