Millimeter-wave multimedia communications: challenges, methodology, and applications

The worldwide opening of a massive amount of unlicensed millimeter-wave spectrum has triggered great interest in developing high-bit-rate multimedia services and applications. Specific challenges for mmWave communication design include large-scale attenuation, atmospheric absorption, phase noise, limited gain amplifiers, and so on. This article aims to define and evaluate important metrics to characterize multimedia QoS and jointly takes these technical challenges into account in the framework of mmWave. To this end, we design a QoS-aware multimedia scheduling scheme to achieve the trade-off between performance and complexity, in which accurate propagation analysis is carried out and suitable countermeasure techniques are pointed out to satisfy the QoS requirements. Moreover, potential multimedia applications are analyzed and possible solutions provided. Illustrative results indicate that the proposed multimedia scheduling scheme can perform efficiently in a practical mmWave communication system.
Visualizers versus verbalizers : Effects of cognitive style on learning with texts and pictures e An eye-tracking study

This study was conducted in order to examine the differences between visualizers and verbalizers in the way they gaze at pictures and texts while learning. Using a collection of questionnaires, college students were classified according to their visual or verbal cognitive style and were asked to learn about two different, in terms of subject and type of knowledge, topics by means of text-picture combinations. Eyetracking was used to investigate their gaze behavior. The results show that visualizers spent significantly more time inspecting pictures than verbalizers, while verbalizers spent more time inspecting texts. Results also suggest that both visualizers' and verbalizers' way of learning is active but mostly within areas providing the source of information in line with their cognitive style (pictures or text). Verbalizers tended to enter non-informative, irrelevant areas of pictures sooner than visualizers. The comparison of learning outcomes showed that the group of visualizers achieved better results than the group of verbalizers on a comprehension test. © 2016 The Authors. Published by Elsevier Ltd.

Issues of cognitive style and learning preferences have been an underlying topic of educational and psychological discussions for years (e.g., Mayer & Massa, 2003; Riding, 1997; Witkin, 1973). Sometimes the whole concept is disputed (e.g., Kirschner & van Merri€ enboer, 2013), sometimes endorsed (e.g., Cassidy, 2004). Regarding visual-verbal cognitive style and its influence on learning from text-picture combinations, relatively few studies have been conducted (e.g., H€ offler, Prechtl,&Nerdel, 2010; Riding& Douglas, 1993). There are even fewer studies which try to examine actual differences between visualizers and verbalizers via a direct observational method like, for example, eye-tracking (e.g., Mehigan, Barry, Kehoe, & Pitt, 2011; Tsianos, Germanakos, Lekkas, Mourlas, & Samaras, 2009). Our study is therefore an attempt to directly examine verbal and visual learners' eye-movements in the context of multimedia learning. Some eye-tracking studies already indicated that visualizers and verbalizers might differ in the way they view pictorial and textual stimuli (Mehigan et al., 2011; (M. Ko c-Januchta), hoeffler@ (G.-B. Thoma), prechtl@uni-
Nonnegative Matrix and Tensor Factorizations - Applications to Exploratory Multi-way Data Analysis and Blind Source Separation

This book provides a broad survey of models and efficient algorithms for Nonnegative Matrix Factorization (NMF). This includes NMFs various extensions and modifications, especially Nonnegative Tensor Factorizations (NTF) and Nonnegative Tucker Decompositions (NTD). NMF/NTF and their extensions are increasingly used as tools in signal and image processing, and data analysis, having garnered interest due to their capability to provide new insights and relevant information about the complex latent relationships in experimental data sets. It is suggested that NMF can provide meaningful components with physical interpretations; for example, in bioinformatics, NMF and its extensions have been successfully applied to gene expression, sequence analysis, the functional characterization of genes, clustering and text mining. As such, the authors focus on the algorithms that are most useful in practice, looking at the fastest, most robust, and suitable for large-scale models. Key features: Acts as a single source reference guide to NMF, collating information that is widely dispersed in current literature, including the authors own recently developed techniques in the subject area. Uses generalized cost functions such as Bregman, Alpha and Beta divergences, to present practical implementations of several types of robust algorithms, in particular Multiplicative, Alternating Least Squares, Projected Gradient and Quasi Newton algorithms. Provides a comparative analysis of the different methods in order to identify approximation error and complexity. Includes pseudo codes and optimized MATLAB source codes for almost all algorithms presented in the book. The increasing interest in nonnegative matrix and tensor factorizations, as well as decompositions and sparse representation of data, will ensure that this book is essential reading for engineers, scientists, researchers, industry practitioners and graduate students across signal and image processing; neuroscience; data mining and data analysis; computer science; bioinformatics; speech processing; biomedical engineering; and multimedia.
Nonnegative Matrix and Tensor Factorization T

T here has been a recent surge of interest in matrix and tensor factorization (decomposition), which provides meaningful latent (hidden) components or features with physical or physiological meaning and interpretation. Nonnegative matrix factorization (NMF) and its extension to three-dimensional (3-D) nonnegative tensor factorization (NTF) attempt to recover hidden nonnegative common structures or patterns from usually redundant data. These lecture notes present several alternative methods for solving NMF/NTF problems.
CONCURRENCY AND COMPUTATION : PRACTICE AND EXPERIENCE Concurrency Computat

This special issue of Concurrency and Computation: Practice and Experience contains selected high-quality papers from the 3rd International Workshop on Workflow Management and Applications in Grid Environments (WaGe2008), which was held on May 25 2008, in Kunming China [1]. The WaGe workshop series aims to provide an international forum for the presentation and discussion of research and development trends regarding workflow support in grid environments. WaGe2008 attracted many international attendants, allowing deep discussion and the exchange of ideas and results related to ongoing research among attendants. FollowingWaGe2007 on August 17, 2007, in Urumqi China, WaGe2008 continues to discuss workflow management in grid environments from different perspectives and areas to tackle different potentials for further research and development. Grid workflow has been under investigation for several years [2–8]. In particular, the special issue titled Workflow in Grid Systems in Concurrency and Computation: Practice and Experience was a key step [7]. The special issue was edited by Professor Geoffrey C. Fox and Professor Dennis Gannon from Indiana University in U.S.A. A follow-up were the special issues in the same journal for WSGE2006 (1st International Workshop on Workflow Systems in Grid Environments) and WaGe2007 [9,10]. This WaGe2008 special issue is another follow-up of the three special issues to further boost the research and development of workflow management and applications in grid environments. Many research and development efforts have been made in the field of workflow management and applications in grid environments such as [2–8,11–19]. More and more people from different areas are trying to facilitate the techniques from their respective areas to tackle tough issues in grid workflow such as resource scheduling, computation reduction, and semantic/knowledge management issues. Accordingly, following the special issue of WaGe2007, this special issue continues to accommodate a range of papers from different perspectives and areas such as service computing and knowledge management to provide some different views and hints for grid workflow research. This special issue contains ten papers based on those that were presented at WaGe2008. They are listed as [20–29]. Research problems in these papers have been analysed systematically, and for specific approaches or models, evaluation has been performed to demonstrate their feasibility and advantages. The 10 papers were selected on this basis and also peer reviewed thoroughly. They are summarized below. Paper [20] is related to Pegasus—a grid/scientific workflow management system. The paper provides an extension to Pegasus whereby resource allocation decisions are revised during workflow
Biological Degradation of Naphthalene: A New Era

Naphthalene is a simplest Polycyclic Aromatic Hydrocarbon (PAH). PAHs are major contaminants of environment, associated with common anthropogenic activities such as oil refineries and incomplete combustion of fossil fuels. PAHs are toxic, mutagenic and carcinogenic. Isolation of naphthalene degrading bacteria is recommended using a complex ONR 7a medium. Present work includes a modified medium with Naphthalene as a sole source of carbon. Four isolates were screened from marine sample collected from Mumbai as well as petroleum soil sample from Trimbak road Satpur, Nashik. Further characterization using morphological and biochemical tests showed resemblance with Gram positive bacteria as well as Gram negative bacteria, belonging to genus such as Micrococcus spp, Bacillus spp, Staphylococcus spp, Pseudomonas spp. These strains were further grown in modified broth for 45 days as well as on ONR 7a agar medium. In turbidometric assay Bacillus spp showed significant growth at 1 mg/ ml of naphthalene concentration. Catechol which is a intermediate product which generated through biodegradation of naphthalene was detected by Winkelmann modified Arnow’s method. All four isolates efficiently degraded naphthalene which was confirmed by Arnow’s test. These naphthalene degraders could be further checked and explored for their efficiency in bioremediation of polluted marine environment and in oil contaminated fields.
Matrix inversion on CPU–GPU platforms with applications in control theory

In this paper, we tackle the inversion of large‐scale dense matrices via conventional matrix factorizations (LU, Cholesky, and LDLT) and the Gauss–Jordan method on hybrid platforms consisting of a multicore CPU and a many‐core graphics processor (GPU). Specifically, we introduce the different matrix inversion algorithms by using a unified framework based on the notation from the FLAME project; we develop hybrid implementations for those matrix operations underlying the algorithms, alternative to those in existing libraries for single GPU systems; and we perform an extensive experimental study on a platform equipped with state‐of‐the‐art general‐purpose architectures from Intel (Santa Clara, CA, USA) and a ‘Fermi’ GPU from NVIDIA (Santa Clara, CA, USA) that exposes the efficiency of the different inversion approaches. Our study and experimental results show the simplicity and performance advantage of the Gauss–Jordan elimination‐based inversion methods and the difficulties associated with the symmetric indefinite case.

Overview of the H . 264 / AVC Video Coding Standard

H.264/AVC is newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goals of the H.264/AVC standardization effort have been enhanced compression performance and provision of a “network-friendly” video representation addressing “conversational” (video telephony) and “nonconversational” (storage, broadcast, or streaming) applications. H.264/AVC has achieved a significant improvement in rate-distortion efficiency relative to existing standards. This article provides an overview of the technical features of H.264/AVC, describes profiles and applications for the standard, and outlines the history of the standardization process.
Extracellular DNA: A Major Proinflammatory Component of Pseudomonas aeruginosa Biofilms

We previously demonstrated that extracellular bacterial DNA activates neutrophils through a CpG- and TLR9-independent mechanism. Biofilms are microbial communities enclosed in a polymeric matrix that play a critical role in the pathogenesis of many infectious diseases. Because extracellular DNA is a key component of biofilms of different bacterial species, the aim of this study was to determine whether it plays a role in the ability of biofilms to induce human neutrophil activation. We found that degradation of matrix extracellular DNA with DNase I markedly reduced the capacity of Pseudomonas aeruginosa biofilms to induce the release of the neutrophil proinflammatory cytokines IL-8 and IL-1β (>75%); reduced the upregulation of neutrophil activation markers CD18, CD11b, and CD66b (p < 0.001); reduced the number of bacteria phagocytosed per neutrophil contacting the biofilm; and reduced the production of neutrophil extracellular traps. Consistent with these findings, we found that biofilms formed by the lasI rhlI P. aeruginosa mutant strain, exhibiting a very low content of matrix extracellular DNA, displayed a lower capacity to stimulate the release of proinflammatory cytokines by neutrophils, which was not decreased further by DNase I treatment. Together, our findings support that matrix extracellular DNA is a major proinflammatory component of P. aeruginosa biofilms.

Dynamic surface grasping is applicable to landing of micro air vehicles (MAVs) and to grappling objects in space. In both applications, the grasper must absorb the kinetic energy of a moving object and provide secure attachment to a surface using, for example, gecko-inspired directional adhesives. Functional principles of dynamic surface grasping are presented, and two prototype grasper designs are discussed. Computer simulation and physical testing confirms the expected relationships concerning (i) the alignment of the grasper at initial contact, (ii) the absorption of energy during collision and rebound, and (iii) the force limits of synthetic directional adhesives.
The morphology of fossil pebbles as a tool for determining their transport processes (Koźmin South lignite open-cast pit, central Poland)

The Koźmin South lignite open-cast pit is the southernmost exposure of Palaeogene (lower Oligocene) deposits in central Poland. This study is focused on Palaeogene pebbles of the so-called Koźmin Gravels, rede- posited in the Neogene sands. These pebbles are not known from the adjacent territory of central Poland and they vary in petrographic composition, shape and surface texture. The classification of the pebble-size particle form is determined as DI/DL (elongation ratio) and DS/DI (flatness ratio). A great number of pebbles are disc-shaped (oblate-shaped) and blade-shaped or they can be classified as platy, bladed and very bladed pebbles. The oblate–prolate index (OP) is less than –2 for 45% of the particles (typical of beach pebbles), the mean sphericity (yp) is 0.56 (typical of beach pebbles), and the mean roundness (RWt) is 0.73 (typical of beach pebbles). The data obtained from SEM analysis of quartz pebble surface micromorphology are characteristic of high mechanical energy of the littoral environment. The surface of some pebbles is excellently polished with v-shaped indentations and grooves. The average composition of the heavy mineral fraction occurring with these pebbles is marked by the predominance of zircon (exceeding 70%). All the above-mentioned data, in the light of extensive literature, indicate that more morphological features of the analysed pebbles have been inherited from the littoral/beach environment. Moreover, a detailed petrographic study was very useful for determining the prove- nance of these pebbles. The most characteristic rocks are greyish-blue quartzes. They are known only from the Sudetes Mts. , situated on the NE slope of the Bohemian Massif. Thus, the rock fragments were transported at least 300 km by rivers from the Sudetes to the littoral/beach zone of the Palaeogene sea. Then, the residually-marine beach pebbles were redeposited into the Neogene debris flow and/or fluvial deposits. The present-day area of the Koźmin South lignite open-cast pit was tectonically active at that time.
Estimating Effectiveness of Twitter Messages with a Personalized Machine Learning Approach Title: Estimating Effectiveness of Twitter Messages with a Personalized Machine Learning

We the undersigned committee hereby approve the attached thesis, " Estimating Effectiveness of Twitter Messages with a Personalized Machine Learning Approach " by Xunhu Sun. In Twitter, many aspects of retweeting behavior, which is the most effective indicator of spreading effectiveness of the tweet, have been researched, such as whether a reader will retweet a certain tweet or not. However, the total number of retweets of the tweet, which is the quantitative measure of quality, has not been well addressed by existing work. To estimate the number of retweets and associated factors, this paper proposes a procedure to develop a personalized model for one author. The training data comes from the author's past tweets. We propose 3 types of new features based on the contents of the tweets: Entity, Pair, and Cluster features, and combine them with features used in prior work. The experiments on 7 authors demonstrate that comparing to the previous features only. Pair feature has a statistically significant improvement on the correlation coefficient between the prediction and the actual number of retweets. We studied all combinations of the 3 types of features, and the combination of the Pair and Cluster features has the best performance overall. As an application, this work can be used as a personalized tool for an author to evaluate his/her tweet before posting it, so that he/she can improve the tweet to achieve more attention.
Overlap-free Karatsuba-Ofman polynomial multiplication algorithms

The authors describe how a simple way to split input operands allows for fast VLSI implementations of subquadratic GF (2)[ x ] Karatsuba-Ofman multipliers. The theoretical XOR gate delay of the resulting multipliers is reduced significantly. For example, it is reduced by about 33 and 25% for n = 2 t and n = 3 t ( t > 1), respectively. To the best of our knowledge, this parameter has never been improved since the original Karatsuba-Ofman algorithm was first used to design GF (2 n ) multipliers in 1990.
Interacting with Personal Fabrication Devices

Personal fabrication tools, such as 3D printers, are on the way of enabling a future in which non-technical users will be able to create custom objects. However, while the hardware is there, the current interaction model behind existing design tools is not suitable for nontechnical users. Today, 3D printers are operated by fabricating the object in one go, which tends to take overnight due to the slow 3D printing technology. Consequently, the current interaction model requires users to think carefully before printing as every mistake may imply another overnight print. Planning every step ahead, however, is not feasible for non-technical users as they lack the experience to reason about the consequences of their design decisions. In this dissertation, we propose changing the interaction model around personal fabrication tools to better serve this user group. We draw inspiration from personal computing and argue that the evolution of personal fabrication may resemble the evolution of personal computing: Computing started with machines that executed a program in one go before returning the result to the user. By decreasing the interaction unit to single requests, turn-taking systems such as the command line evolved, which provided users with feedback after every input. Finally, with the introduction of direct-manipulation interfaces, users continuously interacted with a program receiving feedback about every action in real-time. In this dissertation, we explore whether these interaction concepts can be applied to personal fabrication as well. We start with fabricating an object in one go and investigate how to tighten the feedback-cycle on an object-level: We contribute a method called low-fidelity fabrication, which saves up to 90% fabrication time by creating objects as fast low-fidelity previews, which are sufficient to evaluate key design aspects. Depending on what is currently being tested, we propose different conversions that enable users to focus on different parts: faBrickator allows for a modular design in the early stages of prototyping; when users move on WirePrint allows quickly testing an object’s shape, while Platener allows testing an object’s technical function. We present an interactive editor for each technique and explain the underlying conversion algorithms. By interacting on smaller units, such as a single element of an object, we explore what it means to transition from systems that fabricate objects in one go to turn-taking systems. We start with a 2D system called constructable: Users draw with a laser pointer onto the
