The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR P...

The purpose of this study is to conduct the financial and emission analysis of the Lahendong site as a case study of geothermal powerplant in Indonesia. The outputs of energy model in RETScreen worksheet are power capacity, electricity generation, annual GHG emission reduction, the Internal Rate Return (IRR) and payback period. The sensitivity analyses also were carried out at two scenarios (no...

The mitochondrion has long been known both as a chemical powerplant and as a cellular compartment housing various biosynthetic pathways. However, studies on the function of mitochondria in apoptotic cell death have revealed a versatility and complexity of these organelles previously unsuspected. The mechanisms proposed for mitochondrial involvement in cell death are diverse and highly controver...

Nearpt3 is an algorithm and implementation to preprocess more than 10 fixed points in E and then perform nearest point queries against them. With fixed and query points drawn from the same distribution, Nearpt3’s expected preprocessing and query time are θ(1) per point, with a very small constant factor. The data structure is a uniform grid in E, typically with the same number of grid cells as ...
