Recently, anomaly-based intrusion detection techniques are valuable methodology to detect both known as well as unknown/new attacks, so they can cope with the diversity of the attacks and the constantly changing nature of network attacks. There are many problems need to be considered in anomaly-based network intrusion detection system (NIDS), such as ability to adapt to dynamic network environments,...
Vietnam has a concentrated HIV epidemic, with the highest HIV prevalence being observed among people who inject drugs (PWID). Based on its experience scaling-up robust HIV interventions, Vietnam aims to further strengthen its response by harnessing the preventive benefits of antiretroviral therapy (ART). Mathematical modelling suggests that prioritizing key populations for earlier access to ART, combined...
HCM city is the largest city in Vietnam with about 3,000 km of transport roads for 8 min people. There were many sinkholes appeared on the roads during the period of 2009–2010 years of different diameter. The location of those sinkholes is required to be done to forecast safety transportation in future for. We proposed to use GPR technique for location of these sinkholes in the city by Ramac X3M with...
The Kirchhoff migration plays an important role in converting seismic data into images of geological layers according to viewpoint in the applied geophysics. In this paper, the application of the Kirchhoff migration was used in the case of the high frequency electromagnetic method for specifying GPR velocity model. The measurements of raw GPR data collected by Ramac X3M with 500 MHz frequency in HoChiMinh...
Given D a domain in $$\mathbb{R}^M$$ , G an open set in $$\mathbb{R}^N $$ and E a subset of D verifying the harmonic analogue of ‘Local Polynomial Condition of Leja’ at some point in D. We prove that if f(x, y) is a complex function defined on D × G such that – f(x, ⋅) is harmonic on G for every fixed x ∈ E, – f(⋅, y) is harmonic on D for every fixed y ∈ G, then f is harmonic in (x, y)...
