abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
We explore the role that choice of comparison groups plays in explaining impasse in teacher contract negotiations. We hypothesize that the negotiators select "comparable" districts in a biased fashion such that teachers' salaries in districts that unions view as comparable are higher than teachers' salaries in districts that school boards view as comparable. We also predict that strike activity...
In vitro maturation (IVM) is being increasingly used to treat human infertility, especially as rescue therapy for patients of polycystic ovarian syndrome and ovarian hyperstimulation syndrome. Quality control and the determination of optimal fertilization conditions—important to increase the use of IVM oocytes for embryo production and improve pregnancy success rates—require a detailed understa...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
We present a method of selecting quasars up to redshift ?6 with random forests, supervised machine-learning method, applied Pan-STARRS1 and WISE data. find that, thanks the increasing set known quasars, we can assemble training that enables algorithms become competitive alternative other methods this redshift. candidate for range 4.8–6.3, which includes region around z = 5.5 where is difficult ...
although many scholars had proposed lots research results about online shopping, they are quite vague and hard for enterprisers to practice it. hence, this research observes the online store policies, services, functions, and activities among 17 online shopping platforms in taiwan, china, and hong kong. and, this research (1) finds online stores assessment items by literature review; (2) establ...
