Human activities in the deep North Atlantic
… of the oceans requires data on the extent of human impacts and the wider availability of data on human activities. This study, which aimed to provide the first detailed assessment of the extent of human activities in the deep North East Atlantic, OSPAR Maritime Area, revealed that during 2005 …

Multi-modal on-body sensing of human activities
… the working efficiency. Due to unhandy human-computer-interaction methods this progress does not always result in increased efficiency, for mobile workers in particular. Activity recognition based contextual computing attempts to balance this interaction deficiency. This work …

Analyzing intentions from big data traces of human activities
The rapid growth of big data formed by human activities makes research on intention analysis both challenging and rewarding. We study multifaceted problems in analyzing intentions from big data traces of human activities, and such problems span a range of machine learning, optimization, and …

Impact of climate variability and human activities on water resources.
… (climate change, groundwater dynamics, etc.) and human activities (land-use/land-cover changes, dam construction, etc.) interact and affect the hydrological regime in some selected basins in the semi-arid region of southeastern Spain. To conduct a comprehensive causal analysis, this PhD Thesis …

Discovering Audio-Visual Associations in Narrated Videos of Human Activities
The experimental results show that the algorithm presented in this dissertation successfully discovers the correct associations between video scenes and audio utterances in an unsupervised way despite the imperfect correlation between the video and audio. The algorithm outperforms standard …

Recognition of Human Activities in Hybrid Teamwork with Industrial Robot Systems
… enable novel forms of hybrid teamwork between humans and robots with significant implications for operators. Hybrid teamwork refers to the interaction of operators and robot systems in order to complete a work task in a robot cell. Cells are coherent environments that include robot systems with …

Seaweed diversity in Saldanha Bay and the effects of human activities
… and Langebaan System, but none has looked at how human activities may have affected the seaweed diversity of Saldanha Bay. The major human activities in the Bay include shipping and mariculture. The major human impacts resulting from these activities are species introductions which often lead to a …

Scalable recognition of human activities for pervasive applications in natural environments
Past approaches on the automatic recognition of human activities have achieved promising results by sensing patterns of physical motion via wireless accelerometers worn on the body and classifying them using supervised or semi-supervised machine learning algorithms. Despite their relative success, …

Quantifying groundwater-surface water interactions to improve the outcomes of human activities
… zones and shallow fluvial aquifers, and how human beings influence these interactions and are influenced by them. The three chapters of this dissertation span scales from cm to km and locations from Upstate New York to the Peruvian Andes, but are united by the goal to improve the scientific …

Perchlorate Variations Over 300 Years: Influence of Human Activities, Volcanic Eruptions and Bolide Events
… constitutes a significant health risk to humans because it competitively inhibits iodine uptake by the thyroid gland. Thus, there has been considerable interest in reducing the human exposure to environmental perchlorate by limiting the release of perchlorate from anthropogenic sources. …

Deciphering human activities in complex urban systems : mining big data for sustainable urban future
… phone traces, and other windows onto urban activities has generated much hype about the advent of a new 'urban science.' However, translating such Big Data into a planning-relevant understanding of activity patterns and travel behavior presents a number of obstacles. This dissertation …

USING SOCIALLY SENSED BIG DATA TO MODEL PATTERNS AND GEOGRAPHIC CONTEXT OF HUMAN ACTIVITIES IN CITIES
Understanding dynamic interactions between human activities and land-use structure in a city is a key lens to explore the city as a complex system. This dissertation contributes to understanding the complexity of urban dynamics by gaining knowledge of the interactions between human activities and …

The influence of earth surface movements and human activities on the river Karun in lowland south-west Iran
… “wind gaps” across a fold.The influences of human impacts on major rivers can be distinguished from those of Earth surface movements by suites of river characteristics. There may be significant interactions where these two external factors coincide, most notably where fold uplift and major …

The effect of human activities on the distribution and abundance of the Jordan Lake - Falls Lake bald eagles
I studied the effect of human activities on bald eagle (Haliaeetus leucocephahus) distribution and abundance at Jordan Lake and Falls Lake, North Carolina in 1986 and 1981. Eagles used most of the area available on Jordan Lake, but 63% of the use occurred in the northern 25% of the lake. Eagle use …

Simulating Real-World Human Activities with VirtualCity: A Large-Scale Embodied Environment for 2D, 3D, and Language-Driven Tasks
Embodied environments act as a tool that enables various control tasks to be learned. Within these simulators, having realistic rendering and physics ensures that the sim2real gap for tasks isn’t too large. Current embodied environments focus mainly on small-scale or low-level tasks, without the …

Simulations and projections of major air pollutants over the United States and uncertainty analyses, effects of natural change and human activities
… to continue in the coming decades driven by the human-related activities and natural fluctuations in the Earth climate system. These potential changes would have very important consequences on regional air quality over the contiguous United States due to their effects on atmospheric chemical and …
