Measurements of airborne particles in buildings with low-cost optical particle counters (OPCs) are often inaccurate and subject to uncertainties. This study introduces a methodology improve the performance OPCs measuring indoor through machine learning. A two-month field measurement campaign was conducted an occupied net-zero energy house. The studied (OPC–N2, Alphasense Ltd.) report size fract...

It is important to analyse the degree of genetic variation existing within genome extend base linseed/flaxseed accessions in order preserve, evaluate and use resources accurately successfully. The main aim current investigation was scope spread genomic across different linseed by employing molecular markers (RAPD). DNA 12 amplified with 16 decamer RAPD primers that generated 81 total bands, amo...

We discuss an algorithm (implemented in Matlab) that computes numerically total-degree bivariate orthogonal polynomials (OPs) given an algebraic cubature formula with positive weights, and constructs the orthogonal projection (hyperinterpolation) of a function sampled at the cubature nodes. The method is applicable to nonstandard regions where OPs are not known analytically, for example convex ...

In this paper Wavelength Switching (WS), Optical Burst Switching (OBS) and Optical Packet Switching (OPS) network models are compared. The next future is for WS networks but there is a big investigation effort for development of both OBS and OPS networks, which seem to be further successors in the optical networks world. At the beginning, a brief distinction between considered switching paradig...

Five organophosphates (OPs) (chlorpyrifos, chlorpyrifos methyl, fenthion, malathion, and temephos), 3 pyrethroids (bifenthrin, cypermethrin, and permethrin), and 2 microbial pesticides (Bacillus thuringiensis serovar.israelensis [B.t.i.] and Bacillus sphaericus) were tested as larvicides against a Florida Aedes albopictus population colonized in the laboratory. In addition, 3 insect growth regu...

In swine, five to six days post-insemination, morulae and blastocysts are collected together after uterine flushing. The purpose of this study was to vitrify zona pellucida-intact morulae with Open Pulled Straw (OPS) technology and obtain piglets after transfer. Morulae (200) were vitrified after a two-step equilibration in ethylene glycol, dimethyl sulfoxide and sucrose in Hepes-buffered TCM19...

Organophosphorus pesticides (OPs) were originally designed to affect the nervous system by inhibiting the enzyme acetylcholinesterase, an important regulator of the neurotransmitter acetylcholine. Over the past years evidence is mounting that these compounds affect many other processes. Little is known, however, about gene expression responses against OPs in the nematode Caenorhabditis elegans....

Orienteering problems (OPs) are typically used to model routing and trip planning problems. OP is a variant of the well known traveling salesman problem where the goal is to compute the highest reward path that includes a subset of nodes and has an overall travel time less than the specified deadline. Stochastic orienteering problems (SOPs) extend OPs to account for uncertain travel times and a...

Virtualization systems should be responsible for satisfying the service level objectives (SLOs) for each VM. Performance SLOs, in particular, are generally achieved by isolating the underlying hardware resources among the VMs. In this paper, we show through empirical evaluation that performance SLOs cannot be satisfied with current commercial SSDs. We show that garbage collection is the source ...

The unregulated use of organophosphates (OPs) as pesticides and toxic chemical warfare agents demands their continuous monitoring from a human health perspective. This study describes a fluorescence turn-on sensing assay for the selective quantification of OPs in aqueous medium. Metal complexes of two different Biginelli derivatives were processed in water through a reprecipitation technique. T...
