This paper presents a systematic approach for 3-dimensional (3d) scene modeling based on Time-of-Flight (TOF) technology. Firstly the panoramic point cloud of scene model is built. To achieve that, point cloud data captured in different visual angles are transformed and registered into a panoramic 3d coordinate system. Based on the matching characteristics of feature points in various point clouds
The premise of massive multiple-input multiple-output (MIMO) is based around coherent transmission and detection. Majority of the vast literature on massive MIMO presents performance evaluations over simplified statistical propagation models. All such models are drop-based and do not ensure continuity of channel parameters. In this paper, we quantify the impact of spatially consistent (SC) models
Handling of submicron-sized objects is important in many biochemical and biomedical applications, but few methods today can precisely manipulate this range of particles. We present gradient acoustic focusing that enables flow-through particle separation of submicron particles and cells and we apply it for separation of bacteria from blood lysate to facilitate their detection in whole blood for imp
Copyright law reflects a balance between the competing interests of protection and access. It is often held that this balance has been disturbed by recent technological and related legal developments. This article describes and compares two vehicles to enhance access to information in the online environment, while also taking into account the interest of protection: (i) the introduction of (broade
A low-cost microstrip patch antenna array is proposed in this paper for automotive radar applications in ISM 24 GHz band. The elements of the center-fed array are connected in series to make a compact design with low complexity by obviating Wilkinson power divider. This approach also helps to reduce the dielectric losses of the array. A full-wave electromagnetics (EM) software EMPIRE XPU is used i
We present the early results from a novel experiment to study a particle-laden flow, under a parameter regime relevant to the conditions in planet-forming systems. We investigate the gas-particle interactions to identify the presence of and details regarding the streaming instability, which is theoretically predicted to aid the coalescence of small dust grains to form planetesimals - the macroscop
Much has been written about Percy Bysshe Shelley’s engagement with different aspects of natural philosophy in his poetry and prose. But Shelley’s interest in plants and botany has yet to receive sustained attention. This chapter focusses on the representation of wildness in what it defines as Shelley’s botanical poetry: poems which not only have a plant as their ostensible subject, or which develo
Multinuclear metal active sites are widely used as catalytic reaction centers in metalloenzymes and generally show high catalytic activity. For example, laccases are known to catalyze the oxygen reduction reaction (ORR) to water at a multinuclear copper site with almost no energy loss. The ORR is an important reaction not only in oxygenic respiration but also in future energy generation devices su
The first ab initio aspherical structure refinement against experimental X-ray structure factors for polypeptides and proteins using a fragmentation approach to break up the protein into residues and solvent, thereby speeding up quantum-crystallographic Hirshfeld atom refinement (HAR) calculations, is described. It it found that the geometric and atomic displacement parameters from the new fragHAR
This Letter presents for the first time radio frequency (RF) reliability studies of fully integrated CMOS RF integrated circuits (RFICs) for next generation wireless communication applications involving conformal bodies where wireless communication RFICs will be embedded on ultra-thin flexible packages. As a test case, RF characteristics of a CMOS voltage-controlled oscillator (VCO) chip with mult
Accessibility plays an essential role in determining real estate prices and land use. An understanding of how accessibility and changes in accessibility influence real estate prices is key to making decisions regarding investments in infrastructure projects. From an accessibility point of view, it is not clear that there should be differences in valuation depending on the mode of public transport,
