Ichthyoplankton Composition in the Loop Current and Sargassum Habitats in the Northern Gulf of Mexico
… in an otherwise oligotrophic environment: the Loop Current (LC) a mesoscale oceanographic feature characterized by the transition of environmental conditions of the water mass between the GOM and Caribbean; and <em>Sargassum</em>, a two species assemblage of floating brown algae that is habitat …

Ring Dynamics in the Western Gulf of Mexico
<p>The interaction of a recently-formed Loop Current ring and a fossil ring is studied using observations and a two-layered eddy-resolving general circulation model of the Gulf of Mexico. This interaction is investigated by following the evolution of volume, energy, potential vorticity, angular …

Some design consideration of switching regulator using current-injected control
Open-loop stability analysis of multi-loop current-injected switching regulator is performed using a small signal model containing a power stage, an error processor and a duty cycle pulse modulator. Two design constraints and the effects of various critical control circuit parameters are pinpointed …

CMOS current amplifiers : speed versus nonlinearity
… integrated circuit design using various types of current-mode amplifiers. These circuits are analysed and realised using modern CMOS integration technologies. The dynamic nonlinearities of these circuits are discussed in detail as in the literature only linear nonidealities and static …

Late Holocene hurricane activity and climate variability in the northeastern Gulf of Mexico
… In particular, low-frequency migrations of the Loop Current may exercise control over regional hurricane activity by changing the thermal structure of the upper ocean and influencing the role of storm-induced upwelling on hurricane intensification. A new method for estimating the frequency of …

Control signal transmission through power supply cables of a 3-phase PWM motor
… require feedback data for the drive control loop. Current methods require an independently shielded cable for feedback data transmission. This is due to the fact that high-voltage PWM signals could easily interfere with the feedback signals, which are typically one or more orders of magnitude …

A Comparison of Natural, Living, and Hardened Shorelines Ability to Prevent Coastal Erosion and Maintain a Healthy Ecosystem
… shoreline, since its’ low elevation and the Loop current make it vulnerable to sea level rise. I focused on two manmade methods, hardened, and living shorelines, of coastal protection for when the natural marsh suffers excess erosion rates. Living shorelines are a suite of shoreline …

Taxonomy, Diversity, and Distribution Patterns of Portunid Crab Megalopae in the Northern Gulf of Mexico During Fall of 2003
… crab larvae. Time of day of sampling and currents, including the Loop Current, had the most visible effect on larval densities and distributions. </p>

Assessing the Nursery-Role Function of Pelagic Sargassum for Juvenile Fishes in the Northern Gulf of Mexico
… spatial variables, or surface features (Loop Current or associated eddies). Diets were analyzed for juvenile Gray Triggerfish, Greater Amberjack, Lesser Amberjack, Almaco Jack, and Tripletail, and were found to be spatially variable (especially with distance from shelf break). I observed …

Determining the Viability of Recent Storms as Modern Analogues for North-Central Gulf of Mexico Paleotempestology Through Sedimentary Analysis and Storm Surge Reconstruction
… published sites suggests southerly shifts in the Loop Current may be responsible for regional variability.</p>

Modeling sea surface height in the Gulf of Mexico
… ocean feature in the Gulf of Mexico is the Loop Current (LC) which sheds warm eddies into the Gulf of Mexico at irregular intervals, which adds to the variability in monthly SSH readings beyond seasonal change. Satellite laser altimetry data was used from October 14th 1992 to May 23rd 2007. …

Supercapacitor-assisted Arc Management (SCA2M) technique for DC circuit breakers in low-voltage applications
Direct Current (DC) circuits are gaining popularity due to their compatibility with renewable energy. However, their development is hindered by the lack of mature DC protection, such as circuit breakers. Unlike alternating current (AC), DC lacks natural zero-crossing points, making arc extinction …
