Ocean color satellite sensors are powerful tools to study and monitor the dynamics of suspended particulate matter (SPM) discharged by rivers in coastal waters. In this study, we test the capabilities of Landsat-8/Operational Land Imager (OLI), AQUA&TERRA/Moderate Resolution Imaging Spectroradiometer (MODIS) and MSG-3/Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensors in terms of sp...

We discuss a set of metrics for analyzing human spatial behavior motivated by work in the social sciences; specifically, we investigate individual, attentional, interpersonal, physiological, and organizational factors that contribute to social spacing (proxemics). We then present a pilot study to demonstrate the feasibility of real-time annotation of these spatial behaviors in multi-person soci...

In this paper, we provide an overview of our on-going work using spatial relations for mobile robot navigation. Using the histogram of forces, we show how linguistic expressions can be generated to describe a qualitative view of the robot with respect to its environment. The linguistic expressions provide a symbolic link between the robot and a human user, thus facilitating two-way, human-like ...

This paper addresses a behavior-based fuzzy controller (BFC) for mobile robot wall-following control.The wall-following task is usually used to explore an unknown environment.The proposed BFC consists of three sub-fuzzy controllers, including Straight-based Fuzzy Controller (SFC),Left-based Fuzzy Controller (LFC), and Right-based Fuzzy Controller (RFC).The proposed wall-...

OBJECTIVE The fallopian tube is considered as the site of origin of serous ovarian cancer, and risk-reducing salpingectomy (RRS) has been proposed as a new and safe strategy for preventing ovarian cancer. However, little is known about the public perception of RRS. METHODS We performed a questionnaire survey of 100 healthy female volunteers in November 2014. Questionnaire for this survey incl...

The main challenge that one has to face during the atmospheric correction (AC) of productive inland waters is inability correctly separate aerosol radiance from water-leaving in near-infrared range (NIR) bands. This leads both incorrect estimates parameters and remote-sensing reflectance (Rrs). For Gorky Reservoir, where we are developing regional bio-optical models, situation complicated by la...

Secchi disk depth (ZSD) is used to quantify water clarity as an important water-quality parameter, and one of the most mechanistic models for ZSD quasi-analytical algorithm (QAA), which latest version QAA_v6. There are two in QAA clear turbid waters (referred QAA_clear QAA_turbid). QAA_v6 switches between by setting a threshold value remote sensing reflectance (Rrs, sr−1) at selected reference ...
