Reducing the settlements of soft foundation effectively is a critical problem of high-speed railway construction in China. The new CFG pile-slab structure composite foundation is a ground treatment technique which is applied on CFG pile foundation and pile-slab structure composite foundation. Based on the experience of constructing Beijing-Shanghai high-speed railway in China, the settlement-co...

An outdoor pilot-scale study was undertaken to pretreat municipal solid waste by windrow composting. The raw waste was introduced to active composting without any source separation or pulverization. Pretreatment indicators were developed and used as a tool to measure the optimum level of sorting and waste stabilization. The moisture content of the waste dropped from 68% to 61% and the pile atta...

BACKGROUND We report on a comparative ethno-ornithological study of Zapotec and Cuicatec communities in Northern Oaxaca, Mexico that provided a challenge to some existing descriptions of folk classification. Our default model was the taxonomic system of ranks developed by Brent Berlin. METHODS Fieldwork was conducted in the Zapotec village of San Miguel Tiltepec and in the Cuicatec village of...

in this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. two objective functions, real power loss and energy not supplied index (ens), were utilized. multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

Time-correlated single photon counting (TCSPC) is a fundamental fluorescence lifetime measurement technique offering high signal to noise ratio (SNR). However, its requirement for complex software algorithms for histogram processing restricts throughput in flow cytometers and prevents on-the-fly sorting of cells. We present a single-point digital silicon photomultiplier (SiPM) detector accompli...

The observation of a bright X-ray source by the Chandra X-ray Observatory's High Energy Transmission Grating Spectrometer (HETGS) can be compromised by photon pile-up in the CCD leading to false absorption features in the observed spectrum. A method for removing the e ects of pile-up in a dispersed grating spectrum is presented. The e ectiveness of the technique is demonstrated through its appl...

This study used ethnographic methods to examine the perception of mercury contamination by adolescents in the mining community of Poconé, Mato Grosso, Brazil. In Phase I, 53 students aged 13 to 16 years in six schools presented theatrical sketches about community health risks to generate key terms for a pile sorting activity in Phase II. Mercury was reported by four of the 15 groups (26%). In P...

The goal of this research is to enable a robotic system to manipulate clothing and other highly non-rigid objects using an RGBD sensor. The focus of this thesis is to present various algorithms / models to solve parts of the laundry process (i.e. handling, classifying, sorting, unfolding, and folding). First, a system is presented for automatically extracting and classifying items in a pile of ...

OBJECTIVE Understanding cultural dimensions concerning Mexican and Colombian healthcare workers suffering from dengue to produce information and elements for healthcare and prevention. METHOD This was a cognitive anthropological study. Purposive sampling was used to select 197 healthcare workers in Morelia, Mexico, and Santiago de Cali, Colombia; free associations lists and pile sorting were ...
