In this study, an advanced machine learning model based on artificial intelligence, the Random Forest, was developed and applied to predict the bearing capacity of piles. This model is used as a predefined model applied in the MonteCarlo simulation method to determine the reliability of the pile-bearing capacity.

The diversity and ecology of spiders were studied in the Ngoc Thanh buffer zone of Tam Dao National Park, the Cuc Phuong buffer zone of Cuc Phuong National Park, and the Ba Trai buffer zone of Ba Vi National Park. Spiders were collected by five methods: pitfall traps, litter sampling, tree beating, sweep netting, and visual searches in four types of habitats including secondary forests, artificial forests, shrublands, and home gardens.

The paper presents the results of applying artificial intelligence methods in determining the pile bearing capacity. In this study, an artificial intelligence model namely random forest was developed and applied in pile bearing capacity prediction. The random forest model architecture is optimized by the grid search technique to find the best model.

A plethora of prognostic biomarkers for esophageal squamous cell carcinoma (ESCC) that have hitherto been reported are challenged with low reproducibility due to high molecular heterogeneity of ESCC. The purpose of this study was to identify the optimal biomarkers for ESCC using machine learning algorithms.

A prosthesis is an equipment provided to people who lost one or some parts of their limbs to help them having almost normal behaviors in daily or hard activities. The convenience and intelligence of devices should create easiness and flexibility for users. Artificial devices require interdisciplinary collaboration from neurosurgeons, surgical surgeons, physiotherapists and equipment development. Computer engineering plays a crucial role in the design step, supporting manufacturing, training and recognition to match the desirability of customers.

The present study investigated the natural and artificial regeneration of tree species of semi-arid region. All selected sites of this present study were Taj Nature Park, Shajahan Garden, Paliwal Park, Company Garden and Mau Forest in Agra. In this study, natural and artificial regeneration of tree species were categorized according to family wise and habitat wise. According to family wise, maximum artificial regeneration was 17 percent (Fabaceae) and minimum percentage was 7 percent (Meliaceae).

Brachyuran crabs are the most diverse group of crustaceans. They are found in most marine habitats such as coral reefs, sandy beaches, rocky beaches, mangroves, and seagrass meadows. In this study, we investigated the species composition of brachyuran crabs at 10 sampling locations belonging to three habitats (mangrove forest, artificial dykes, sandy beaches) at Duyen Hai town on August (rainy season) and December (dry season) in 2017. We found that there were 22 species belonging to 10 genera of six families present in the research area. The Ocypodidae family is the most abundant, with 45.

“Acacia hybrids” refers to the inter-specific hybrids of A. mangium and A. auriculiformis, including natural, artificial and polyploid ones. The superiorities of selected acacia hybrid are fast growth, straight stem form, small branches, high productivity, and high ratio of wood utilisation. Acacia hybrids are recognized as having a higher pulping potential and greater soil improvement ability than that of the parental species, which may be shown to have 2.5-13 times larger numbers of nitrogen - fixing nodules on its roots in nursery stage.

One of the software engineering interests is quality assurance activities such as testing, verification and validation, fault tolerance and fault prediction. When any company does not have sufficient budget and time for testing the entire application, a project manager can use some fault prediction algorithms to identify the parts of the system that are more defect prone.

We address air quality (AQ) forecasting as a regression problem employing computational intelligence (CI) methods for the Gdansk Metropolitan Area (GMA) in Poland and the Thessaloniki Metropolitan Area (TMA) in Greece. Linear Regression as well as Artificial Neural Network models are developed, accompanied by Random Forest models, for five locations per study area and for a dataset of limited feature dimensionality.

This Minor Field Study (MFS) was performed by Teresia Lindberg and Anna Nylander, who are both studying Eco-toxicology at Uppsala University in Sweden. The report is a Master´s thesis for Teresia Lindberg. The Swedish International Development Agency (Sida) finances a number of so-called Minor Field Studies for students or young people to carry out a research project in a developing country. The study usually takes place in one of Sida´s target countries and is part of a local Sida-sponsored aid programme.

Men experiencing troublesome urinary symptoms before treatment should be offered a urologi- cal assessment. Men undergoing treatment for prostate cancer should be warned of the likely effects of the treatment on their urinary function. Healthcare professionals should ensure that men with troublesome urinary symptoms after treatment should have access to specialist continence services for assessment, diagnosis and conservative treatment. This may include coping strategies, along with pelvic floor muscle re-education, bladder retraining and pharmacotherapy.

The ARIES methodology is based on explicit conceptualizations (ontologies: Villa, Athanasiadis et al. 2009) that lay out first of all a novel vision of ES, based on the breakdown into individual benefits, each of which is modeled independently, then linked to the others. Domain ontologies in ARIES result from a large-scale expert consensus. Artificial intelligence techniques (machine reasoning, pattern recognition) examine source data and extract from the ontologies models that best represent the situation at hand.
