Background: This work evaluated the efficiency of common ultrasound stimulation (U.S.S) types on bacterial growth in vitro using clinically relevant conditions.Objective: To estimate different frequencies ultrasound bactericidal ability on bacteria in bacteria of Pseudomonas Aeruginosa. Methods: Six types of U.S.S (continuous wave, 7w/cm2, 20 KHz; continuous wave, 35w/0.8L, 40 KHz; continuous ...

Location privacy-preserving mechanisms (LPPMs) have been extensively studied for protecting users' location privacy by releasing a perturbed to third parties such as location-based service providers. However, when user's locations are released continuously, existing LPPMs may not protect the sensitive information about real-world activities, “visited hospital in last week” or “regularly commuti...

This paper presents a multi-objective mixed-integer non-linear programming model for congested multiple-server discrete facility location problem with uniformly distributed demands along the network edges. Regarding capacity of each and maximum waiting time threshold, developed aims to determine number locations established facilities their corresponding assigned servers such that traveling dis...

Continuous location problems and network location problems are generally viewed as completely different classes of problems. We will show in this paper that despite the classical distinction between continuous and discrete optimization, there are many similarities that can be exploited both for the development of new location models and for the derivation of theoretical properties and solution ...
