improving mechanical properties of composites based on strength-to-weight ratio has been gained much attention in various applications. having the most resistant and at the same time the lightest and the most economical structure is believed as an aim in these applications. these three factors are usually opposed to each other. so, applying optimization algorithms for improving mechanical prope...

The increasing penetration of non-synchronous renewable energy sources (NS-RES) alters the dynamic characteristic, and consequently, the frequency behaviour of a power system. To accurately identify these changing trends and address them in a systematic way, it is necessary to assess a large number of scenarios. Given this, we propose a frequency stability assessment framework based on a time-s...

Usually the generalized sidelobe canceller (GSC) beamformer requires additional highpass pre-filtering due to insufficient suppression of low frequency directional interference, and it deteriorates the bandwidth quality of speech enhancement, especially for small size microphone array. This paper proposes a new GSC beamformer with multiple frequency dependent norm-constrained adaptive filters (...

Consider the link bandwidth allocation for transport of correlated traac on a single link with nite buuer capacity under a maximum allowable delay constraint d max. In our measurement architecture, traac is decomposed into three frequency regions: low-frequency (LF) traac in 0 < j!j ! L , high-frequency (HF) traac in j!j ! H and mid-frequency (MF) traac in ! L < j!j < ! H. The zero-frequency co...

Here, we demonstrate how comparative sequence analysis facilitates genome-wide base-pair-level interpretation of individual genetic variation and address two questions of importance for human personal genomics: first, whether an individual's functional variation comes mostly from noncoding or coding polymorphisms; and, second, whether population-specific or globally-present polymorphisms contri...

Constraints are factors that limit evolutionary change. A subset of constraints is developmental, and acts during embryonic development. There is some uncertainty about how to define developmental constraints, and how to formulate them as testable hypotheses. Furthermore, concepts such as constraint-breaking, universal constraints, and forbidden morphologies present some conceptual difficulties...

In this paper, we have study the optimal design for synchronous wireless information and power transfer (SWIPT) in downlink multiuser orthogonal frequency division multiplexing (OFDM) systems, where the users gather energy and explain information by using the same type of signals received from a stable access point (AP). For the transmission of information, we have to consider two types of nume...
