This paper develops a two factor real options model of the harvesting decision over infinite rotations with mean reverting stochastic prices using a rigorous HamiltonJacobi-Bellman methodology. The harvesting problem is formulated as a Linear Complementarity Problem which is solved numerically using a fully implicit finite difference method. This approach is contrasted with Markov Decision Proc...
Due to the small energy harvesting rates and stochastic energy harvesting processes, energy management of energy harvesting senor is still crucial for body network. Transmission polices for energy harvesting sensors with Markov chain energy supply over time varying channels is formulated as an infinite discounted reward Markov Decision Problem under the assumption of geometric distribution of s...
Managing scientific data requires tools that can track complex provenance information about digital resources and workflows. RDF triples are a convenient abstraction for combining independentlygenerated factual statements, including statements about provenance [1]. Harvesting is a strategy for asynchronously acquiring distributed information for the purposes of aggregation and analysis [2]. Har...
In this paper, we propose a hybrid polling Medium Access Control (MAC) protocol with Human Energy Harvesting capabilities, called HEH-BMAC, designed for Wireless Body Area Networks (WBANs). The proposed protocol uses a dynamic schedule algorithm to combine User Identification polling (ID) and Probabilistic Contention (PC) random access, adapting the network operation to the random, time-varying...
The selection of the right timing for harvest oil palm fresh fruit bunch (FFB) can affect outcome quality, which further imply quality crude (CPO). Truly ripen fruits boost yield and oil. determination ripeness is done with an approach to estimating time cycle approximate number that are detached from their bunches (loose-fruit). study aimed investigate exact harvesting variations in loose at e...
background and objectives: milk thistle (silybum marianum), a medicinal plant of the asteraceae family that have been used long time ago, in the treatment of liver disease. sowing date of this plant has not been determined, therefore, this study was necessary. this plant was identified as a weed, this plant is identified as a weed, while silymarin in the seeds are used in the anti-hepatitis and...
This study aims to investigate the essential oils content of Thymbr Spicata L. in two times before flowering and full flowering in shirpenah area in Ilam Province. Both samples were dried out in shade and without humidity. Then 50 grams of each sample were powdered after obtaining the essential oils by hydro distillation using a Clevenger apparatus for 2 hours. Resulted oils were dried by anhyd...
Various solutions are utilized widely for the isolation, harvesting, sorting, testing and transplantation of neural stem cells (NSCs), whereas the effects of harvesting media on the biological characteristics and repair potential of NSCs remain unclear. To examine some of these effects, NSCs were isolated from cortex of E14.5 mice and exposed to the conventional harvesting media [0.9% saline (S...
