This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...

In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

The most commonly used empirical approach to address issues of attention constraint is evaluate the degree of interference in dual or multiple tasks. The purpose of this study was designing software to estimate the relative interference between multiple tasks and determine its validity in performance prediction of simultaneous multiple tasks. in order to assess the validity of software, 46 stud...

The domestic politics of international status unfolds beyond its foreign policy implications. Sometimes actors engage in to pursue their political aims.

A scaling procedure for skew-symmetric data is illustrated using results from a survey by the Institute of Politics at Harvard University. These data were discussed in an April 27, 2012 op-ed column from the New York Times by Charles Blow. The op-ed columnist for the New York Times, Charles Blow, is known for his creative graphics and visual representation of data. One of his more recent column...

Ecuador is located between latitudes 2°N and 5°S and limits the Pacific Ocean on the west, Colombia on the north, and Peru on the south and east (Fig. 1). Its capital, Quito, stands at 2850 m (9350 ft.) above sea level. The country has four different geographic regions, the Coast (west of the Andes), the Sierra (Interandean highlands), the Amazon (east of the Andes), and the Insular region (Gal...
