Analysis of tolerable capacity limits of intermittent photovoltaic power connected to the Namibian national electricity grid
… intermittent solar PV power and to determine the capacity limit beyond which the Namibian electricity grid system will become unstable due to an increase in intermittent solar PV systems feeding power into the grid system. Data of interest was obtained from collected reports, journal articles, and …

Assessing the technical and financial viability of broadband satellite systems using a cost per T1 minute metric
… of the system becomes the limiting factor. These limits include satellite power resources, achievable link margins, and rain attenuation. A computer simulation is developed to model the complex interactions between the capacity limits and distributed market models.

Production model based on Lean Manufacturing and SLP to increase efficiency for a company in the metal mechanical sector
… However, this growth has been stopped by capacity limits and a wide range of troubles and delays that occur during the process, most of the Peruvian companies don’t have developed methodologies like the companies abroad whose production efficiency is good. As a response to this problem, we …

Data compression application to the MIL-STD 1553 avionics data bus.
… F/A-18 C/D Aircraft is approaching message capacity on its MIL-STD-1553 buses. To slow this assent to capacity limits, one possible solution implements data compression techniques to increase bandwidth. In these efforts, this thesis examines different lossless compression schemes to find …

Setting optimal production lot sizes and planned lead times in a job shop system
… costs subject to workload variability and capacity limits. We model the interplay of three key components in the job shop, namely, the production frequency for each part, the variability of production at each work station, and the level of parts inventory. We consider two operating tactics …

Interhemispheric communication during face processing
… leading to an exploration of the impact of capacity limits for face processing on the experimental paradigm. Evidence that interhemispheric communication may occur asymmetrically in the direction of right hemisphere to left hemisphere was also obtained. Findings are discussed within the …

Downlink Transmission and Caching Strategies for Backhaul-Limited Cloud Radio Access Networks
… are connected to a central processor (CP) via capacity-limited backhaul links. Two fundamental and different downlink transmission strategies are studied, namely the data-sharing strategy and the compression strategy. In the data-sharing strategy, the backhaul links connecting the CP and the …
