Abstract This paper reports detailed propagation analyses of mm-wave indoor networks based numerical simulations of the wireless coverage and measurements of the propagation coefficient at 28 and 38 GHz. Additionally, ma...

Topicality of comparative study in Foreign Direct Investments (FDI) is determined by the need to deepen analysis of economic activity challenges and opportunities related to cross-border investments. Research in FDI tren...

PURPOSE: To develop and validate an automated computational tool for calculating a slice-specific volume computed tomography (CT) dose index (CTDIvol), a water-equivalent diameter (Dw), and size-specific dose estimates (...

Abstract Background People with disabilities—more than a billion people worldwide—are frequently excluded from social and political life, and often experience stigmatising attitudes and behaviours from people without...

Abstract Background Antimicrobial resistance is a significant public health concern with the establishment of antimicrobial stewardship in hospitals being increasingly obligatory. Perspectives and insights of health mana...

The purpose of this work is to analyse the impact of COVID-19 on teaching methods, focusing on the Home Based Learning approaches (HBL) utilised at short notice to support students at the Robert Gordon Univ...

Abstract This paper presents a bandpass filter based on a substrate integrated E-plane waveguide (SIEW) structure for wireless applications, at X-band. The SIEW geometry allows the development of new horizontally polariz...

Abstract This paper presents a cloud-based data-driven design optimization system, named DADOS, to help engineers and researchers improve a design or product easily and efficiently. DADOS has nearly 30 key algorithms, in...

Abstract Robotic splicing of steel arches is a challenging task that is necessary to realize the grasping and docking of steel arches in a limited space. Steel arches often have a mass of more than 200 kg and length of m...

Abstract As for the complex operational tasks in the unstructured environment with narrow workspace and numerous obstacles, the traditional robots cannot accomplish these mentioned complex operational tasks and meet the ...

The reliability of oil and gas transportation depends heavily on weld quality during pipeline construction. This study investigates the effect of gas metal arc welding (GMAW) current on API 5 L GrB pipeline weld joint. W...

Abstract The hot or cold processing would induce the change and the inhomogeneous of the material mechanical properties in the local processing region of the structure, and it is difficult to obtain the specific mechanic...

Abstract Introduction Tobacco is one of the biggest public health problems and a major risk factor for various non-communicable diseases (NCDs). An important aspect of tobacco control strategy could include modifications...

Abstract The operation of a shield tunnel boring machine (TBM) in a high-strength hard rock stratum results in significant cutter damage, adversely affecting the thrust and torque of the cutter head. Therefore, it is ver...

Abstract The problem of this paper is the high contact stress at the point of contact between the cam and the follower. A pear cam and roller follower mechanism were studied and analyzed for different position of the fol...
