Travel time estimation (TTE) is a critical function in intelligent driving systems. Current research and applications related to TTE primarily focus on urban environments. The objective of this study develop methods that are applicable wilderness areas characterized by plateau mountainous topography. We selected Transformer, which has greater robustness capturing long-distance dependencies than LSTM, Transformer-based model. model simultaneously integrates positional encoding multi-head...

In field driving activities, off-road areas usually lack existing paths that can be directly driven on by ground vehicles, but their surface environments still satisfy the planning and passage requirements of some vehicles. Additionally, path methods face limitations in complex characterized undulating terrains diverse land cover types. Therefore, this study introduces an improved A* algorithm adapted 3D model real scenes is constructed. A velocity curve fitted evaluation function to reflect...

In the animal production industry, manure odors can be a potential nuisance to neighboring residents. A more suitable metric other than odor concentration and intensity is required evaluate dispersion or on-farm odor-reducing technologies. An parameter was developed better describe by integrating concentration, intensity, hedonic tone values into an index. order mathematically define index, assumption made that index equivalent geometric mean of tone. The mathematical models for...

Multisource data fusion technology integrates the strengths of various sources, addressing limitations relying on a single source. Therefore, it has been widely applied in fields such as lithological classification and mineral exploration. However, traditional deep learning algorithms fail to distinguish importance different features effectively during fusion, leading insufficient focus model. To address this issue, paper introduces ResHA network based hybrid attention mechanism fuse from...

N-butanol is used as a reference odor to train panelists and field sniffers measure concentrations intensities, respectively. It has different characteristics from that of livestock odors. Odors headspace samples stored swine manure wastewater sludge were analyzed with GC/MS. Seventeen identified compounds selected candidate constituents an artificial (ASO). Twenty-four formulations these developed. Three trials conducted evaluate 24 based on six criteria: the formulation would be safe human...

In order to mitigate the influence of outliers in point clouds on voxel down-sampling results and accuracy cloud registration practical applications, method Point Cloud Library (PCL) has been improved. First, nearest-neighbor distance is applied search for actual that closest calculated centroid a volume. This then used as reserved replace voxel, which helps preserve local detailed features edge contour cloud. Secondly, considering voxels located at edges often contain large number these are...

Odor measurements were compared among four olfactometry laboratoriesacross North America. Odorous air samples collected from livestock facilities weredelivered to the laboratories and odor concentration of each sample wasmeasured by olfactometers at same time. A certified commercial n-butanol,air mixture 40ppm, was used as a reference odor. Relatively large variations wereobserved between laboratories. By applying normalization model data fourlaboratories, standard error decreased 36%,...
