Readout errors are a significant source of noise for near term intermediate scale quantum computers. Mismeasuring qubit as 1 when it should be 0 occurs much less often than mismeasuring have been 1. We make the simple observation that one can improve readout fidelity computers by applying targeted X gates prior to performing measurement. These placed so expected number qubits in state is minimi...

In this paper we start off by reviewing the literature on how to extend the meanvariance portfolio model to multi-stage portfolio problems. We then apply a multiperiod portfolio selection model to power generation assets, which is based on a reallocation methodology with scenario tree. Two solution approaches are used: the multi-period rebalancing model and the global solution one. These approa...

Distributed file systems are key technology for cloud computing applications. In such file system, each node having storage as well as computing functionalities. A file is partitioned into a number of chunks allocated in distinct nodes so that data processing can be performed in parallel. Specifically, in this study, we suggest offloading the load rebalancing task to storage nodes by having the...

This paper extends the model of Engler et al. (2007) on the adjustment of the US current account to a three-country world economy. This allows an analysis of the differential impact of a reversal of the US current account on Europe and Asia. In particular, the outcomes under different exchange rate policies are analysed. The main nding is that large factor re-allocations from non-tradables to t...

Optimal asset allocation strategies are often derived in continuous time models, but have to be implemented in discrete time. It has been shown that in models with stochastic volatility or jumps, an investor who just uses the continuous time strategy in discrete time has to trade at least daily to profit from having access to derivatives. In this paper, we determine the optimal investment strat...

sensitivity of an electromagnetic type metal detector is directly related to stability, the higher the required sensitivity, the more frequently the rebalancing controls will have to be adjusted. thus, for maximum sensitivity in the head ,the use of automatic drift compensation network is necessary in order to cancel out the signal resulting from a slow drift in the coil system due to the tempe...
