Dynamic optimisation problems are difficult to solve because they involve variables that change over time. In this paper, we present a new HookeJeeves based Memetic Algorithm (HJMA) for dynamic function optimisation, and use the Moving Peaks (MP) problem as a test bed for experimentation. The results show that HJMA outperforms all previously published approaches on the three standardised benchm...

Mobile Cloud Computing (MCC) integrates mobile computing and cloud computing aiming to extend mobile devices capabilities through offloading techniques. In MCC, many controlled experiments have been performed using mobile applications as benchmarks. Usually, these applications are used to validate proposed algorithms, architectures or frameworks. The task of choosing a specific benchmark to eva...

We present the first published large-scale study of mobile web tracking. We compare tracking across five physical and emulated mobile devices with one desktop device as a benchmark. Our crawler is based on FourthParty; however, our architecture avoids clearing state which has the benefit of continual observation of (and by) third-parties. We confirm many intuitive predictions and report a few s...

zataria multiflora boiss is used in traditional folk remedies as antiseptic, analgesic, carminative, anthelmintic medication. the main components of zataria multiflora are phenolic compounds such as thymol and carvacrol. the aim of this study was developed a simple and rapid method for determination of the thymol in different extracts of zataria multiflora by hplc method. the dried aerial parts...

the aim of this paper is to develop a rapid, and highly sensitive quantitative hplc fingerprint method with multiple indicators by using the compound chinese medicine wuwei changyanning granule and 5 herbs in the prescription. the quantitative fingerprint chromatogram with multiple indicators was investigated. ⅰ)6 compositions included rutin, gallic acid, chlorogenic acid, atractylenolideⅰ, pac...

Occupational and toxicological studies have demonstrated adverse health effects from exposure to toxic air contaminants. Data on outdoor levels of toxic air contaminants have not been available for most communities in the United States, making it difficult to assess the potential for adverse human health effects from general population exposures. Emissions data from stationary and mobile source...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

This paper investigates optimization in dynamic environments where the numbers of optima are unknown or fluctuating. The authors present a novel algorithm, Dynamic Population Differential Evolution (DynPopDE), which is specifically designed for these problems. DynPopDE is a Differential Evolution based multi-population algorithm that dynamically spawns and removes populations as required. The n...

This thesis proposes, implements, and evaluates in terms of correctness and performance, an online metrics collection strategy to assist mobile application adaptation with the support of a mobile object framework. The solution is based upon an abstract representation of the system, which holds containers aggregating metrics for each specific component comprising a mobile object framework, inclu...
