Strobe Light Effects On Stress and Avoidance Behavior in Fishes and Distribution of Zooplankton in Lake Oahe, South Dakota
During the summers of 2004 and 2005 strobe lights were evaluated for their influence on (1) stress (plasma cortisol) and avoidance (distance moved away) responses across a broad range of fish taxa and (2) abundance (no./l) and distribution of zooplankton in Lake Oahe, South Dakota. To quantify …

Behavioral Responses of Rainbow Smelt to Sensory Deterrent Systems
… underwater sound projector array (SPA) and (2) strobe lights as fish deterrents for avoidance and acclimation behavior of rainbow smelt; 3) to determine physical characteristics that affect light attenuation in Lake Oahe; and 4) to evaluate predator-prey interactions of rainbow smelt and …

Factors Influencing Rainbow Smelt Entrainment Through Oahe Dam, South Dakota
… diel and seasonal water release patterns, strobe lights. From 1997 to 1999, rainbow smelt and other fish species were collected in the Oahe Dam tailrace (tailrace) from May through October or November with paired 1-m diameter, 1-mm (bar measure) mesh Nitex plankton nets. Additionally, water …

Speed of the Earth : illusion and experience of speed and scale
… through the use of rapidly sequenced strobe lights sited in a straight east/west axis line, which create a momentary event of pure light that is both corporeal and illusive. The proposed sculpture will also addresses the concept of relative perception, the light event itself creating a …

Influence of Predation on Least Tern and Piping Plover Productivity Along the Missouri River in South Dakota
… chick escape shelters, exclosure cages, and strobe lights as passive deterrent devices. Piping plover nest success was significantly increased (P < 0.001) with the use of exclosure cages. Piping plover and least tern nest success and chick survival appeared to be enhanced with the use of …

An Investigation of the Effectiveness of A Strobe Light As An Imminent Rear Warning Signal
Strobe lights have been used successfully in many transportation applications to increase conspicuity. It was hoped that a strobe signal could also be applied to more effectively warn distracted drivers of an unexpected rear end conflict. This "proof of concept study" used a 2 x 2 between-subjects …

In-situ tests of sound-bubble-strobe light barrier technologies to prevent the range expansions of Asian carp
… Chicago Sanitary and Ship Canal. Sound-bubble-strobe light barrier (SBSLB) technologies may have the potential to slow Asian carp range expansions. A sound-bubble barrier was 95% effective at deterring adult bighead carp passage in a hatchery raceway experiment. In 2009-2010, I tested the …

Optimization of an Emergency Response Vehicle's Intra-Link Movement in Urban Transportation Networks Utilizing a Connected Vehicle Environment
… response vehicle (ERV) through sirens and/or strobe lights. These traditional warning systems do not give any recommendation about how to react, leaving the drivers confused and often adopting unsafe behavior while trying to open a passage for the ERV. In this research, an advanced intra-link …

Accelerated settling of particulate matter by ’marine snow’ aggregates
… lying on the bottom plate is illuminated by strobe lights mounted in the wall of the cylinder and photographed by a camera which is positioned below the bottom plate. Flux is determined as the number of aggregates arriving during the time interval between photographic frames (# area-1 …
