Scientific observations on the quality and reliability of combine harvesters have shown that all delays equipment, 32...35% total operating time, technical failures account for 17.4...19.8%. Most were observed with failure parts, mechanical transmissions, hydraulic systems, etc. Quantitative analysis harvester has most occur in operation cutting device, namely finger bar mower. The working hypo...

We present the case of a 72-year-old man with hemoptysis after a thoracic projectile injury, which occurred while mowing the lawn. Chest radiograph followed by a computed tomography angiogram revealed a metallic foreign body in the right middle lobe of the lung. The patient underwent a right anterolateral thoracotomy where the object was successfully retrieved. The patient had an uneventful pos...

In this dissertation, we focus on developing simultaneous localization and mapping (SLAM) algorithms with a robot-centric estimation framework primarily using monocular vision sensors. A primary contribution of this work is to use a robot-centric mapping framework concurrently with a world-centric localization method. We exploit the differential equation of motion of the normalized pixel coordi...

Autonomous (i.e., robotic) mowers have recently garnered interest with the public and within turfgrass industry. However, limited research has been conducted on their use for mowing warm-season turfgrasses. An experiment was at University of Florida’s West Florida Research Education Center (Jay, FL, USA) to investigate performance an autonomous mower using a lower than recommended height-of-cut...

Eukaryotic evolution has been characterized by intron loss. In eukaryotes, the proposed mechanisms of intron loss are exonization, random genomic deletion, retroprocessing and most recently, horizontal gene transfer followed by gene conversion (HGT-GC). Here we investigate the mechanism of intron loss from the mitochondrial cox2 gene, which in previous studies has shown a variable intron distri...

"Mow-lawning" is a colloquial term referred to actively cutting grass using reel mower, typically at faster than normal pace in order maximize exercise benefit and minimize time, with the emphasis on physical action of mowing only secondarily resulting lawn care. While mow-lawning remains relatively uncommon United States, adoption this practice by those healthy enough engage level required can...

We consider the problem of optimal position liquidation with the aim of maximizing the expected cash flow stream from the transaction in the presence of a temporary or permanent market impact. We use a stochastic programming approach to derive trading strategies that differentiate decisions with respect to different realizations of market conditions. The scenario set consists of a collection of...
