A Novel Approach to Trojan Horse Detection in Mobile Phones Messaging and Bluetooth Services
( Juan A. Ortega ),( Daniel Fuentes ),( Juan A. Lvarez ),( Luis Gonzalez-abril ),( Francisco Velasco ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.8
A method to detect Trojan horses in messaging and Bluetooth in mobile phones by means of monitoring the events produced by the infections is presented in this paper. The structure of the detection approach is split into two modules: the first is the Monitoring module which controls connection requests and sent/received files, and the second is the Graphical User module which shows messages and, under suspicious situations, reports the user about a possible malware. Prototypes have been implemented on different mobile operating systems to test its feasibility on real cellphone malware. Experimental results are shown to be promising since this approach effectively detects various known malware.

Pulque is a fermented beverage prepared with the sap of agave species, consumed since pre-Hispanic times in Mexico. In the sixteenth century, spaces called pulquerías were established for the sale and consumption of pulque. The demand for pulque became so high that there were more than 1500 pulquerías in Mexico City early twentieth century, but due to socio-cultural factors, the popularity of pulque plummeted. Currently, there are few pulquerías in Mexico City, and these are the main spaces for the consumption of this beverage in the metropolis. The pulque sold in pulquerías comes from eight localities, largely from Nanacamilpa, Tlaxcala. People working in pulquerías have deep knowledge and specific practices to keep pulque in good conditions and to prepare it in a wide spectrum of flavors by mixing the fermented beverage with fruits, vegetables or seeds. We recorded 69 types of pulque mixtures. Pulquerías allow the economic maintenance of working families in urban and rural contexts, are spaces of socialization, and identity and help the conservation of an ancient traditional beverage.
Malignant Glomus Tumor of the Peritoneum: Case Report
Sandra Baleato-González,Roberto García-Figueiras,Maria Virginia Trujillo-Ariza,Juan Jose Carrera-Álvarez 대한영상의학회 2014 Korean Journal of Radiology Vol.15 No.1
Glomus tumors are usually benign tumors that occur in the skin and soft tissues of the extremities. Visceral locations, such as stomach, intestines or lung, are extremely rare because glomus bodies are rare or absent in these organs. This report describes our experience in a 47-year-old woman diagnosed with a peritoneal malignant glomus tumor. This finding has not been previously reported.
Numerical investigation of truck aerodynamics on several classes of infrastructures
Alejandro Alonso-Estébanez,Juan J. del Coz Díaz,Felipe P. Álvarez Rabanal,Pablo Pascual-Muñoz,Paulino J. García Nieto 한국풍공학회 2018 Wind and Structures, An International Journal (WAS Vol.26 No.1
This paper describes the effect of different testing parameters (configuration of infrastructure and truck position on road) on truck aerodynamic coefficients under cross wind conditions, by means of a numerical approach known as Large Eddy Simulation (LES). In order to estimate the air flow behaviour around both the infrastructure and the truck, the filtered continuity and momentum equations along with the Smagorinsky–Lilly model were solved. A solution for these non-linear equations was approached through the finite volume method (FVM) and using temporal and spatial discretization schemes. As for the results, the aerodynamic coefficients acting on the truck model exhibited nearly constant values regardless of the Reynolds number. The flat ground is the infrastructure where the rollover coefficient acting on the truck model showed lowest values under cross wind conditions (yaw angle of 90), while the worst infrastructure studied for vehicle stability was an embankment with downward-slope on the leeward side. The position of the truck on the road and the value of embankment slope angle that minimizes the rollover coefficient were determined by successfully applying the Response Surface Methodology.
