The Earth s climate is very complex and highly variable, making it difficult to measure and model small changes that occur over decadal and longer time scales
The Maps captured by robots in real environment are usually incomplete, distorted, and noisy. To evaluate the quality of these kind of maps is an important

We demonstrate Hanbury-Brown Twiss interferometry without a beamsplitter, by employing a single-mode optical fiber coupled to a multi-element superconducting
Identification and recognition of three dimensional (3D) objects in range data is a challenging problem. We propose a novel method to fulfill the task through
In this paper, we analyze the state of current human and automatic evaluation of topic-focused summarization in the Document Understanding Conference main task

We report on propagation tests carried out in a subterranean tunnel to support improved wireless communications for urban search and rescue robots. We describe
Computer experiments, that is, experiments performed using a mathematical model of a physical or chemical process implemented using a computer simulation are
For over 35 years, each IC generation has doubled the transistor count while cutting the cost per function in half. This progress, described by Moore's Law, has

Volatile organic compounds (VOCs) emitted by building materials and products have been shown to significantly impact human health and comfort. As a result, the
Building and space ventilation rates are primary determinants of indoor pollutant levels and occupant exposures, and the impacts of ventilation on health and

Buildings are a major and growing source of energy consumption and as such, contribute to the significant problems associated with energy dependence and growing
NIST is studying ultrafine particles (UFP) between 2 nm and 64 nm produced by common indoor combustion and electric appliances. Experiments were conducted in an

We demonstrate that the higher-order resonant modes of a near-field microwave probe can be used for quantitative relative permittivity measurements of low-loss
The neutralization energy carried by highly charged ions (HCIs) provides a fundamentally independent method for localizing energy on a targets surface
