The layout of irrigation water distribution networks is usually branched. In most of the previous studies pipe sizes of the network had been optimized assuming a predetermined layout of the distribution system. However, only few researches have focused on the simultaneous layout and pipe size optimization. In this study a hybrid approach is adapted for simultaneous layout and pipe size optimiza...

The current consensus in exercise physiology is that the repeated bout effect always appears after few eccentric exercise sessions. This is the first attempt to challenge this tenet, by exploiting specificity in muscle plasticity. More specifically, we examined whether the opposing adaptations in muscle induced after concentric and eccentric exercise can attenuate and/or remove the repeated bou...

Isokinetic moment ratios of the hamstrings (H) and quadriceps (Q) muscle groups, and their implication in muscle imbalance, have been investigated for more than three decades. The conventional concentric H/Q ratio with its normative value of 0.6 has been at the forefront of the discussion. This does not account for the joint angle at which moment occurs and the type of muscle action involved. A...

BACKGROUND AND OBJECTIVES It is not well understood whether the left ventricular geometry is associated with such diastolic parameters as the left atrial volume and the left ventricular filling pressure, as assessed by the Doppler indices. Accordingly, this study aimed to evaluate the influence of the left ventricular geometry on the left atrial volume and the left ventricular filling pressure,...

In this paper, a genetic algorithm is presented for the simultaneous layout and pipe size optimization of water distribution networks and its e ciency is evaluated and compared using di erent selection mechanisms. An engineering concept of reliability is used, in which the number of independent paths from source nodes to each of the demand nodes is considered as a measure of reliability. The me...

The optimal layout of stamping blanks is a complicated problem under the control of multicircumstances, and it cannot be best solved by any single algorithm. In order to solve this problem, the paper proposed a new kind of algorithm combining CHNN and genetic algorithm. It set up models for irregular parts, and these irregular parts were processed by using the surrounding rectangle methods and ...

Layout generation in the late analog CMOS design is challenging by its increasing layout constraints and performance requirements. However, iterative refinement on manual design damages the productivity of analog layout. Therefore, it is more efficient to enroll the know-how from existing design instead of generating a new one. To contend with time-consuming analog layout for more possibilities...

A comprehensive review on the approaches for synthesizing low side lobe concentric ring array (CRA) antennas is given. An Iterative Convex Optimization (ICO) based layout synthesis technique proposed peak side-lobe level (PSLL) minimization over a given circular field-of-view in steerable uniform-amplitude (UA-CRA) antennas. For number of rings and uniformly-distributed elements each ring, ICO ...
