Motivated by the asset-liability management of a nuclear power plant operator, we consider the problem of finding the least expensive portfolio which outperforms a given set of stochastic benchmarks at a sequence of future dates. For a specified loss function, the shortfall with respect to each of the benchmarks weighted by this loss function must remain bounded in expectation by a given thresh...

In this paper, the multiple-input multiple-output (MIMO) transmit beampattern matching problem is considered. The problem is formulated to approximate a desired transmit beampattern (i.e., an energy distribution in space and frequency) and to minimize the cross-correlation of signals reflected back to the array by considering different practical waveform constraints at the same time. Due to the...

In this paper, we investigate the existence of infinitely many solutions for a bi-nonlocal equation with sign-changing weight functions. We use some natural constraints and the Ljusternik-Schnirelman critical point theory on C1-manifolds, to prove our main results.

Multiple feature occurrences, cross-linguistically attested as undesirable phonological configurations, may be resolved in at least two ways. One is by imposing a requirement that at most one feature of a given type may occur in a linguistic form. Another is by restricting the distribution, rather than the number, of features within a linguistic form; that is, by imposing like distributions on ...

Seismic waves are filtered as they pass through soil layers, from bedrock to surface. Frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground motion characteristics. Therefore, it is important to consider the impact of the soil properties on the evaluation of earthquake ground motions for the design of structures. Soil ...

Free vibration of soil often occurs during earthquakes. Since the vibration caused by earthquake does not have (steady state harmonic vibration) continuity, the alluvium vibrates with its natural frequency between two natural seismic waves. This study evaluates the effect of piles on the period of free vibration of a soil layer using numerical method. In the first stage, using analytical equati...

This paper discusses the practical constraints of testing Radio Frequency Integrated Circuit (RFIC) devices in a Multiple-Input Multiple-Output (MIMO) topology. Techniques to optimize test equipment setup and operation for MIMO architectures are detailed. Because RFICs are tested at a device level, this paper focuses on MIMO compliance testing and characterization within a cabled RF environment...
