This work studies the temporal imbalance that processes experience when operating on a modern multicore cluster, and develops hierarchical algorithms that tolerate this imbalance. A micro-benchmark is used to investigate the nature of process imbalance with perfectly balanced workloads, and understand the nature of interversus intra-node imbalance. These insights are then used to develop imbala...

The subcarrier signal to interference-plus-noise ratio expression for orthogonal frequency division multiplexing systems impaired by in-phase/quadrature (I/Q) imbalance is a ratio of correlated random variables. In its original form, a quadruple integral is required to evaluate the exact average subcarrier SINR which is cumbersome to compute numerically. We show that the quadruple integral can ...

Abstract The occurrence of thrombotic complications, which can result in excess mortality and morbidity, represent an imbalance between the pro-thrombotic fibrinolytic equilibrium. mainstay treatment these complications involves use antithrombotic agents but despite advances pharmacotherapy, there remains a significant proportion patients who continue to remain at risk. Endogenous fibrinolysis ...

the square map is one of the functions used in cryptography. for instance, the square map is used in rabin encryption scheme, block cipher rc6 and stream cipher rabbit, in different forms. in this paper, we study statistical properties of the output of the square map as a vectorial boolean function. we obtain the joint probability distribution of arbitrary number of the upper and the lower bits...

Short-term periods of increased resistance exercise training are often used by athletes to enhance performance, and can induce functional overreaching (FOR), resulting in improved physical capabilities. Non-functional (NFOR) or overtraining syndrome (OTS), occur when demand is applied for prolonged without sufficient recovery. Overtraining (OT) describes the imbalance between recovery, diminish...

The inphase/quadrature (I/Q) amplitude and phase imbalance effects are studied in coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. An analytical model for the I/Q imbalance is developed and supported by simulation results. The results indicate that the I/Q imbalance degrades the BER performance considerably. Keywords—Coherent detection, I/Q imbalance, OFDM, optical...
