Abstract

More than six million people died of the COVID-19 by April 2022. The heavy casualties have put people on great and urgent alert and people try to find all kinds of information to keep them from being inflected by the coronavirus. This research tries to find out whether the mobile health text information sent to peoples devices is correct as smartphones becoming the major information source for people. The proposed method uses various mobile information retrieval and data mining technologies including lexical analysis, stopword elimination, stemming, and decision trees to classify the mobile health text information to one of the following classes: (i) true, (ii) fake, (iii) misinformative, (iv) disinformative, and (v) neutral. Experiment results show the accuracy of the proposed method is above the threshold value 50 percentage, but is not optimal. It is because the problem, mobile text misinformation identification, is intrinsically difficult.

6. Alternative Technique to Asymmetry Analysis-Based Overlapping for Foot Ulcer Examination: Scalable Scanning

Abstract

Asymmetry analysis based on the overlapping of thermal images proved able to detect inflammation and, predict foot ulceration. This technique involves three main steps: segmentation, geometric transformation, and overlapping. However, the overlapping technique, which consists of subtracting the intensity levels of the right foot from those of the left foot, can also detect false abnormal areas if the projections of the left and right feet are not the same. In this paper, we present an alternative technique to asymmetry analysis-based overlapping. The proposed technique, scalable scanning, allows for an effective comparison even if the shapes and sizes of the feet projections appear differently in the image. The tested results show that asymmetry analysis- based scalable scanning provides fewer false abnormal areas than does asymmetry analysis -based overlapping., Comment: Journal of Diabetes & Metabolism, 2012

The growing diversity of the Internet brings in many organizations under different authorities with conflicting interests. Each such organization forms an Autonomous System (AS), with its own policy regulating network traffic across its boundaries to protect valuable network resources. As a result, a policy violation at any intermediate AS may cause a packet to be silently dropped before reaching its destination. The Border Gateway Protocol (BGP) was introduced to solve this packet-dropping problem in the mid-1990s, followed by a series of revisions. Currently, BGP is the dominant protocol in this field. However, BGP is a distance-vector and hop-by-hop protocol, resulting in a loss of reachability information for some destinations, even though feasible routes to those destinations may physically exist. Unreachable destinations under BGP are not necessarily truly unreachable. To overcome this deficiency, this paper presents a source policy route discovery protocol to supplement BGP. Simulation results show that almost all the false negative unreachable destinations can be resolved by the proposed protocol.
