The selection criteria for multiphase boosting options remain somewhat subjective and are frequently influenced by the vendors’ data, which may mask potential limitations of this emerging technology. Existing literature on multiphase pumping tends to focus on a certain pump type for a specific field application, but does not provide more-generalized criteria for the selection of multiphase boos...

Calcium-based catalysts are of high interest for glycerol polymerization due to their catalytic activity and large availability. However, poor stability under reaction conditions is an issue. In the present study, we investigated Ca-hydroxyapatites (HAps) as one most abundant Ca-source in nature. A stochiometric, Ca-deficient Ca-rich HAps were synthesized tested reaction. Deficient stochiometri...

The integrated use of non-terrestrial network (NTN) entities such as the high-altitude platform station (HAPS) and low-altitude (LAPS) has become essential elements in space-air-ground networks (SAGINs). However, complexity, mobility, heterogeneity NTN resources present various challenges from system design to deployment. This paper proposes a novel approach designing heterogeneous consisting H...

In this paper, we propose a novel Deep Reinforcement Learning Evolution Algorithm (DRLEA) method to control the antenna parameters of High-Altitude Platform Station (HAPS) mobile reduce number low-throughput users. Considering random movement HAPS caused by winds, throughput users might decrease. Therefore, that can dynamically adjust based on in coverage area improving users’ throughput. Diffe...

Biomacromolecules have been used as templates to grow hydroxyapatite crystals (HAps) by biomineralization to fabricate mineralized materials for potential application in bone tissue engineering. Silk sericin is a protein with features desirable as a biomaterial, such as increased hydrophilicity and biodegradation. Mineralization of the silk sericin from Antheraea pernyi (A. pernyi) silkworm has...

This paper reviews the state of the art and current trends towards 3G and 3GC mobile satellite systems that are being planned in parallel or within the International Mobile Telecommunications (IMT-2000) framework. The subject is firstly approached by introducing the key and enabling technologies both for satellites and high altitude platform stations. After having introduced an overall picture,...
