Bullet sized [PDF]

open access: yesShort Film Studies, 2020
Abstract Taking as a touchstone A. L. Kennedy's observation about the disproportionate impact of the short story compared to its size, this article explores the extent to which David Von Ancken's adaptation of Tobias Wolff's text finds, via montage and perspective, a cinematic analogue to the aesthetic form of the short story.

Response-surface-model-based system sizing for nearly/net zero energy buildings under uncertainty [PDF]

open access: yes, 2018
Properly treating uncertainty is critical for robust system sizing of nearly/net zero energy buildings (ZEBs). To treat uncertainty, the conventional method conducts Monte Carlo simulations for thousands of possible design options, which inevitably leads

Sizing Assessment of Islanded Microgrids Considering Total Investment Cost and Tax Benefits in Colombia

open access: yesEnergies, 2022
This paper deals with the optimal sizing of islanded microgrids (MGs), which use diesel generators to supply energy in off-grid areas. The MG under study integrates photovoltaic (PV) and diesel generation, a battery energy storage System (BESS), and an ...

Buffer Sizing for 802.11 Based Networks [PDF]

open access: yes, 2011
We consider the sizing of network buffers in 802.11 based networks. Wireless networks face a number of fundamental issues that do not arise in wired networks. We demonstrate that the use of fixed size buffers in 802.11 networks inevitably leads to either
