Deductive object-oriented databases are intended to integrate the deductive and object-oriented database techniques to combine the best of two approaches and to overcome their inherent shortcomings, with a number of deductive object-oriented database languages proposed. However, most of these languages are only structurally object-oriented. Important behaviorally object-oriented features such a...

substituted naphthofurans and naphthopyrans were constructed at high temperature from allyl or propargyl naphthyl ethers via claisen rearrangement in moderate to good yields. also, substituted (trimethylsilyl)-naphthofurans were synthesized from the corresponding naphtofurans.

• New models of evaporating liquid films in heated tubes are developed. Liquid particles allowed to overtake one another. Non-uniform evaporation proposed. Models derived from the physical conservation laws. described by time-delay equations relating inflow and outflow. The paper presents novel control-oriented transport for a falling film evaporator. In this context, our goal consists qualitat...

Aiming at the key optimization problems of wireless sensor networks in complex industrial application environments, such as optimum coverage and reliability network, a novel topology coverage-oriented strategy for based on wolf pack algorithm is proposed. Combining characteristics structure idea redefines group’s wandering surprise behavior. A head mutation proposed, which increases neighborhoo...

Abstract The rise in percentage of deteriorated bridges coupled with the escalation maintenance costs call for systematic bridge management systems. Therefore, this research paper introduces an exponential chaotic differential evolution (ECDE) model optimizing plans at both project and network levels. developed optimization is envisioned on addressing performance, economic, social, environmenta...
