Catching the response time tail in the cloud

As modern service systems are pressured to provide competitive prices via cost-effective capacity planning, especially in the paradigm of cloud computing, service level agreements (SLAs) end up becoming ever more sophisticated, i.e., fulfilling targets of different percentiles of response times.…

Linearity improvement of microwave amplifiers by special harmonic loads

In this paper, the effects of special harmonic loads are presented in the case of microwave amplifiers. The third-order intercept point (IP3) and the 1-dB compression point (P1dB) of the amplifier are improved with the use of special harmonic loads.…

Sub-optimal initialization for blind equalization with fast convergence in OFDM/OQAM modulation

This paper deals with blind equalization in orthogonal frequency division multiplexing/offset quadrature amplitude modulation (OFDM/OQAM) systems. Blind equalization is an interesting solution with regard to the spectral efficiency since no pilot is used for the signal recovering, but blind iterative…

Sum-MSE minimization for MIMO interference channels under CSI mismatch

This paper considers multiple-input multiple-output (MIMO) interference channels, where the robust transceiver is designed under imperfect channel state information (CSI). Our objective is to minimize the sum mean-square-error (MSE) subject to per-transmitter power constraints. An iterative algorithm is proposed to…

Sparse Uncorrelated Linear Discriminant Analysis for Undersampled Problems

Linear discriminant analysis (LDA) as a well-known supervised dimensionality reduction method has been widely applied in many fields. However, the lack of sparsity in the LDA solution makes interpretation of the results challenging. In this paper, we propose a new…

Band anticrossing and luminescence emission in dilute InAs1−x−yNxSbyquaternary alloys

In this paper, we calculate the luminescence of the dilute quaternary InAs1−x−yNxSby semiconductor using a microscopic approach. The theory starts with the band anticrossing model applied to both conduction and the valence band to generate input for analytical approximations that lead…

Analysis on the LSP and shell modes of a silver-strip plasmonic nanolaser

We consider the two-dimensional (2-D) problem of the H-polarized electromagnetic eigenmodes that can exist on a silver nanostrip placed in the centre of an active shell in the form of circular quantum wire (QW). Both the lasing mode frequency and…
