While polynomial-time approximation algorithms remain a dominant notion in tackling computationally hard problems, the framework of parameterized complexity has been emerging rapidly in recent years. Roughly speaking, the analytic framework of parameterized complexity attempts t…
This dissertation examines the history, evolution, and influence of Google News—Google’s news aggregation service—from the late 1990s to 2019. There are scattered studies about Google News, but no systematic and substantive research on what is, at this writing, its nearly two de…
Big data is much discussed in business, government, and healthcare, but the ascendance of the data-driven approach has consequences beyond these areas, detectable in both discourse and cultural practices such as self-quantification. The questions explored in this work, “Can the …
This thesis consists of two main parts. In the first part a detailed wireless sensor node model based on CC2430, a system-on-chip IEEE802.15.4 compliance wireless transceiver manufactured by Chipcon, is proposed. The accuracy of the proposed sensor node model is compared with so…
An automated computerized algorithm for identifying and blocking pornographic content was designed. Primitive information on pornography is studied and used to determine if a given image falls under the pornographic category. In this thesis the pornography image is defined as im…
Recently, automatic age progression has gained popularity due to its numerous applications. Among these is the frequent search for missing people, in the UK alone up to 300,000 people are reported missing every year. Although many algorithms have been proposed, most of the metho…
The growing demand for faster connection to the Internet service and wireless multimedia applications has motivated the development of broadband wireless access technologies in recent years. WiMAX has enabled convergence of mobile and fixed broadband networks through a common wi…
