As a consequence of this popularity, the malware targeting Android smartphones has also mushroomed. Android malware is one of the major security issues and fast growing threats facing the Internet in the mobile arena, today. So, in this context, DNS (Domain Name System) is widely misused by miscreants in order to provide internet connection within malicious networks and botnets. In our experiments, we use the MalGenome dataset in order to generate network traffic. Besides, most of the malware we examine use DNS in order to obtain the IP address of their command and control servers. Then, the problem of determining the DNS queries done by the malware through devices without modifying the firmware or rooting smartphone, is very important and it poses a big challenge. From traces we generated from apps under test, we can extract malicious URLs invoked by the malware.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system was modeled using the Euler-Lagrange formalism and the system's experimental resonant frequencies were obtained using the peak-picking method. An advantage of modal control for experimental applications is that it is not necessary to derive a mathematical model for the system to apply such controller which performs well for displacement and vibration reduction while keeping global stability. In particular, this paper addresses the case of an external force exciting the base of the structure. Numerical results demonstrate the controller's performance.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"332 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114059961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The estimator is based on no linear model that considers the evolution of the neural activity as non-homogeneous. These conditions can help to improve the solution of the neuromagnetic inverse problem and to find spatially focus sources.

The assessment of this problem is even more complex when considering the uncertainties that usually determine the long-term evolution of the system. Moreover, and from the point of view of regulators and policy makers, an optimal assessment is of great interest because the lack of coordination between the two types of investment can jeopardize competition and efficiency in the whole electricity sector. In that context, this paper proposes an improved method to assess the joint expansion planning of the generation and transmission segments, considering the inherent flexibility of investments belonging the first segment, using the Real Options valuation approach, considering the Least Squares Monte Carlo method. A numerical example has been tested considering a system of two nodes. It is shown that the consideration of investments flexibility allows increasing the social benefit through the coordinated planning of the generation and transmission segments.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115853551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This will allow DMs determining: a) how an ICT investment is expected to impact the VC of their business unit, b) how an ICT investment actually impacted the VC of their business unit, and c) whether the INTVAL impact obtained is aligned with the strategic objectives pursued in terms of how many value activities intended to be impacted were actually impacted at the extent predicted.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123542030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voltage measurements have been conducted at end users sites, and also in substations of the distribution system. Compliance has been analyzed in reference to the national power quality standard issued by SIGET (Superintendencia General de Electricidad y Telecomunicaciones). This standard includes limits and percentiles for slow voltage variations, harmonic distortion, and short term flicker severity index For harmonic voltage distortion, compliance evaluation applying SIGET standard is compared to application of IEEE 519-2014. Additionally, three electromagnetic phenomena not included in SIGET standard have been analyzed: short duration rms voltage variations (sags), voltage unbalance and long term flicker severity index The paper is conclusive regarding steady state electromagnetic phenomena: Measured Values comply with SIGET standard, except at two specific sites. High levels of short term flicker severity index (Pst) have been found at these two sites. Measurements conducted in 2016 and 2017, also show an increase trend in the levels of individual odd harmonics distortion components that are multiple of three, and also an increase in the long term flicker severity index, caused by an structural change of non-linear loads. At last, the estimation of voltage sag indices presented in this paper show that voltage sags represent the main power quality problem in the distribution system in El Salvador.","PeriodicalId":400949,"journal":{"name":"2017 IEEE 37th Central America and Panama Convention (CONCAPAN XXXVII)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129659392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, DNS (Domain Name System) is widely misused by miscreants in order to provide Internet connection within malicious networks. Here, we propose an infrastructure for monitoring the Android applications in a platform-independent manner, introducing hooks in order to trace restricted API calls used at runtime of the application.
