Implementable Wireless Access for B3G Networks - III: Complexity Reducing Transceiver Structures

This article presents a comprehensive overview of some of the research conducted within Mobile VCE’s Core Wireless Access Research Programme,1 a key focus of which has naturally been on MIMO transceivers. The series of articles offers a coherent view of how the work was structured and comprises a compilation of material that has been presented in detail elsewhere (see references within the article). In this article MIMO channel measurements, analysis, and modeling, which were presented previously in the first article in this series of four, are utilized to develop compact and distributed antenna arrays. Parallel activities led to research into low-complexity MIMO single-user spacetime coding techniques, as well as SISO and MIMO multi-user CDMA-based transceivers for B3G systems. As well as feeding into the industry’s in-house research program, significant extensions of this work are now in hand, within Mobile VCE’s own core activity, aiming toward securing major improvements in delivery efficiency in future wireless systems through crosslayer operation

Blind Philhellenes vs. Selective Consumers of Foreign Cultures: A Reassessment of the Ancient Greco-Roman Literary Record’s Portrayal of the Gauls in Light of New Archaeological Evidence

The issue of perspective is intrinsic to historiography. This is evident in the ancient Greco-Roman literary record, specifically the limits placed on its value to modern academics by the ethnographic biases of its authors. However, with the rise of the post-processual approach to archaeology over the past thirty years, modern historians have begun to address this issue. By utilizing the impartial records offered by excavation, these scholars have increasingly managed to circumvent ancient authorial subjectivity and reevaluate the modern preconceptions it created of the world of antiquity. An example of the archaeological record\u27s value in reassessing the inherent prejudices of the ancient literary record can be seen in the instance of the archaic-era Ionian Greek colony of Massalia. While the ancient writings on Massalia have provided modern historians with a limited overview of this Greek polis, their potential for offering genuine insight is denigrated by the cultural bias evident in their overly positive portrayal of Massalia and their pejorative treatment of the native Gauls. However, by examining archaeological excavations of Massalia and surrounding Gallic sites, modern historians have begun to sidestep this Hellenic literary bias and its associated cultural stereotypes, and gain valuable insight into the much more complex reality of relations and interactions that existed between the Massaliotes and their Gallic neighbors. Overall, although ancient historians portray Massalia as a powerful bastion of civilizing Hellenism amongst the barbarian tribes of Gaul, the modern archaeological record indicates that this characterization is largely false, and that in reality Massalia\u27s Gallic trading partners were not Philhellenes who attempted to imitate Greek culture, but selective consumers who incorporated a limited range of Greek goods into their own existing cultural systems

Strategy management through quantitative modelling of performance measurement systems

This paper is based on previous works on performance measurement and on quantification of relationships between factors which affect performance. It demonstrates how tools and techniques developed can be used to evaluate the performance of alternative strategic choices through a quantitative approach to modelling of performance measurement systems. The paper provides a brief background to the research problem and preceding works. The tools and techniques used are briefly introduced. Use of these tools and techniques to evaluate the performance of alternative manufacturing strategies is demonstrated. Finally, the capability of the approach to deal with dynamic environments is demonstrated using sensitivity analysis

We Will Never Speak of It: Evidence of Hitler\u27s Direct Responsibility for the Premeditation and Implementation of the Nazi Final Solution

The “Intentionalist vs. Functionalist” debate has raged amongst academic historians for decades, centered on the question of whether Adolf Hitler personally premeditated and instigated the Final Solution, or whether the idea and its implementation developed more gradually out of a collaborative effort within the ranks of the Nazi bureaucracy. This paper seeks, through careful analysis of Nazi primary source materials, to establish an “Intentionalist” argument in favor of Hitler being directly responsible for the premeditation and implementation of the infamous Nazi attempt to systematically annihilate the entirety of Europe’s Jewish population

Dual Constraint Problem Optimization Using A Natural Approach: Genetic Algorithm and Simulated Annealing

Constraint optimization problems with multiple constraints and a large solution domain are NP hard and span almost all industries in a variety of applications. One such application is the optimization of resource scheduling in a pay per use grid environment. Charging for these resources based on demand is often referred to as Utility Computing, where resource providers lease computing power with varying costs based on processing speed. Consumers using this resource have time and cost constraints associated with each job they submit. Determining the optimal way to divide the job among the available resources with regard to the time and cost constraints is tasked to the Grid Resource Broker (GRB). The GRB must use an optimization algorithm that returns an accurate result in a timely mam1er. The Genetic Algorithm and the Simulated Annealing algorithm can both be used to achieve this goal, although Simulated Annealing outperforms the Genetic Algorithm for use by the GRB. Determining optimal values for the variables used in each algorithm is often achieved through trial and error, and success depends upon the solution domain of the problem. Although this work outlines a specific grid resource allocation application, the results can be applied to any optimization problem based on dual constraints

Project-Based Learning (PBL) via Segmented Lectures and Peer-Reviews: Programed Instruction for APA Style Literature Reviews

Twenty-first century pedagogical trends desire collaborative learning by students in and out of the classroom environment. Lesson plans proposed here are based on multiple approaches to actively engage students, promote proficiency, reinforce student-learning outcomes (SLO), and attain course outcomes (CO). Advocated is a programed instruction of APA Style via segmented lectures with interspersed student activities, and scaffold assignments with corresponding peer- reviews and peer evaluation. Project-based learning (PBL) is facilitated because students learn to instruct peers via sequenced reviews

On the Unicity of Smartphone Applications

Prior works have shown that the list of apps installed by a user reveal a lot about user interests and behavior. These works rely on the semantics of the installed apps and show that various user traits could be learnt automatically using off-the-shelf machine-learning techniques. In this work, we focus on the re-identifiability issue and thoroughly study the unicity of smartphone apps on a dataset containing 54,893 Android users collected over a period of 7 months. Our study finds that any 4 apps installed by a user are enough (more than 95% times) for the re-identification of the user in our dataset. As the complete list of installed apps is unique for 99% of the users in our dataset, it can be easily used to track/profile the users by a service such as Twitter that has access to the whole list of installed apps of users. As our analyzed dataset is small as compared to the total population of Android users, we also study how unicity would vary with larger datasets. This work emphasizes the need of better privacy guards against collection, use and release of the list of installed apps.Comment: 10 pages, 9 Figures, Appeared at ACM CCS Workshop on Privacy in Electronic Society (WPES) 201
