Based on an overall consideration of factors affecting road safety evaluations, the Bayesian network theory based probability risk analysis was applied to causation accidents. By taking Adelaide Central Business District (CBD) in South Australia as a case, structure established by integrating K2 algorithm with experts’ knowledge, and Expectation-Maximization that could process missing data adopted conduct parameter learning Netica, thereby establishing model for Then Netica used carry out...

A self-powered biosensor for monitoring the maximal lactate steady state (MLSS) during exercise has been developed intelligently assisting training system. It presented to create poly (vinylidene fluoride) (PVDF)/Tetrapod-shaped ZnO (T-ZnO)/enzyme-modified nanocomposite film through an efficient and cost-effective fabrication process. This sensor can be readily attached skin surface of tester. Due piezoelectric coupling effect, this monitor/sense analyze physical information in real-time...

This work proposes an all-quartz integrated lens antenna for the first time. The feed and materials are both made of quartz. is designed to at 26 GHz has advantages small size reduced surface wave loss. Two antennas, a hemispheric extended lens, demonstrated. area 30 × mm2 height 16 mm, while with same area, mm. measured peak gain 15.49 dBi, simulated 17.68 dBi. electric-field distribution was analyzed, two antennas were on PCB substrate comparative analysis. results validate impact effect...

This paper presents a novel Ku-band parasitic patch antenna based on MEMS technology. The consists of two substrates that are bonded together. lower substrate houses the main and ground layer, while upper supports patch. To minimize dielectric loss, is fabricated using double-layer suspended film process, combining parylene C Spin-on-glass (SOG) materials. also SOG. proposed achieves measured bandwidth 30% (11.1~15.01 GHz), peak gain 8.57 dBi, compact size 0.87 × 0.09 λ03.

Neonicotinoid insecticides are one of the most important commercial used worldwide. The potential toxicity residues present in environment to humans has received considerable attention. In this study, a novel Ochrobactrum sp. strain D-12 capable using acetamiprid as sole carbon source well energy, nitrogen for growth was isolated and identified from polluted agricultural soil. Strain able completely degrade with initial concentrations 0–3000 mg·L−1 within 48 h. Haldane inhibition model fit...

Poly (ethylene terephthalate) (PET) constitutes an important composition of environmental microplastics (MPs). This study was to explore the degradation PET MPs in high-temperature composting and also make attempt for enhanced by exogenous addition thermophilic hydrolase. Herein, six 220 L composters were applied perform composting, with half designated group hydrolase added. After 20 days, exhibited a notable reduction (21.1%) weight resulted 32.8% MPs. is corroborated increase terephthalic...

The 2008 Wenchuan earthquake triggered tens of thousands landslides, resulting in rich loose materials for the 8.13 debris flows. Longchi Town southwest China's Sichuan Province was one worst hit areas both by and source generated coseismic landslides Longxi River watershed upper Min are widely distributed cover an area 7.97 km2. volume has reached as high 13,364.99×104 m3. After catastrophic flows occurred on August 13, 2010, there were still large amounts remaining. This presented major...

The textile industry significantly contributes to environmental pollution through its use of synthetic dyes, especially sulfur black, known for toxicity and resistance degradation. This research focuses on a fungal strain, Aspergillus sp. strain DS-28, isolated from activated sludge, which exhibits an exceptional ability biodegrade black dye. study systematically assessed the biodegradation capacity this series experiments conducted over 7-day period. Analytical techniques including...

Aspergillus sp. D-23 was obtained by ultraviolet-diethyl sulfate (UV-DES) compound mutagenesis from C18 that the α-galactosidase purified from. According to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and non-denaturing polyacrylamide (Native-PAGE), enzyme demonstrated apparent homogeneity. The monomeric α-galactosidase’s native molecular weight 125 kDa. optimal temperature of 65 °C, 75% initial activity could be maintained between 45 55 °C. Its pH 5.0 with good...

Three dimensional laser scanning technology has been widely used in machine vision and reverse engineering. Plane segmentation is an important step for object recognition the point cloud obtained by scanner. Traditional plane method cannot obtain a specific accurately when normal unknown. This paper proposes new based on Mean Shift clustering RANSAC with constraints initial to segment whose Firstly, down sampled using Voxel Grid method. Secondly, algorithm uses sphere actual of be segmented....

Signalized metering roundabouts are equipped with advanced loop detectors and traffic signals that can reduce vehicle queuing lengths, especially on the dominant approach, when unbalanced flow conditions occur. At a roundabout, changeable lengths location of determine signal phase times, which in turn affect length each approach. To date, most studies have focused performance comparisons between normal metered roundabouts, but failed to evaluate effect detector locations formations. In...
