This study discusses the creation method of topographic models from LIDAR data with the view of using them for tsunami simulation. Additionally, an examination regarding the improvement of simulation accuracy and topographic approximation of topographic models is carried out for the coastal region of Taro area of Miyako City in Iwate Prefecture in Japan using LIDAR data, comparing the simulatio...

Recent technology development and penetration of advanced metering infrastructure (AMI), building control systems, the internet-of-things (IoT) in built environment are providing detailed information on operation, performance, user’s comfort behavior. Building owners can obtain a wide range energy consumption details at various levels time granularity to augment their decisions as they manage o...

PURPOSE To investigate the feasibility of adequate reading by recipients of future prosthetic visual implants through simulation in sighted observers. METHODS Four normally sighted subjects used a video headset to view short-story segments at a sixth grade reading level, presented in 6- to 11-word paragraphs through a pixelizing grid defined by five parameters (dot size, grid size, dot spacin...

A method to perform distribution grid power flow calculations using stochastic load profiles and meteorological data is presented in this paper. The method is based on two previously presented algorithms: The first algorithm generates stochastic household load profiles and the second generates stochastic irradiance data, both using a sampling rate of one minute. Applying this data to an electri...

BACKGROUND Epidemiological findings of higher injury incidence during the latter stages of soccer match-play have been attributed to fatigue. OBJECTIVE To examine the interaction of physical and cognitive responses during soccer-specific intermittent exercise. METHOD Ten semi-professional soccer players completed a 90-minute laboratory-based treadmill protocol replicating the activity profi...

When viewed in hourly intervals, a solar photovoltaic (PV) system appears to have a more stable output than usual. However, there are short-term rapid variations in its generation output that result from transient cloudiness and weather disturbances in the atmosphere. By using Monte Carlo simulations applied to a Markov model, this study demonstrates the shortterm intermittency of the transient...

There is increasing urgency towards integration of renewable sources into electricity generation so as to minimize greenhouse gas (GHG) emissions. Renewable power are highly specific in prevalence, both regionally and temporally, their utilization at utility scale for round-the-clock supply poses the problem matching capacity demand every instant time. In present work, we propose a model that i...

We are exploring algorithms to predict the aggregate power output of many photovoltaic systems in a single geographic region on a 3-hour time horizon at 5-minute steps (a 36-step forecast) based only on observed system power. The goal is to correctly identify upcoming “ramp events,” or large positive or negative deviations from a long-term trend over a short time period (Sevlian and Rajagopal, ...

We present an approach to simulate time-synchronized, one-minute power output from large photovoltaic (PV) generation plants in locations where only hourly irradiance estimates are available from satellite sources. The approach uses one-minute irradiance measurements from ground sensors in a climatically and geographically similar area. Irradiance is translated to power using the Sandia Array P...
