RF PROPAGATION ENVIRONMENT AWARENESS FOR SMART MOBILE AD-HOC NETWORKS

Urban canyon environments represent a significant challenge to wireless communications, a satisfactory solution for which remains to be proven. We present RF Propagation Environment Awareness (RPEA), utilising ‘smart’ ad hoc, or self-forming and self-healing networks that are capable of storing and exploiting local propagation geometry information. An empirical radio propagation environment model, comprising a loss model specific to the local urban topology, is used to optimise network operation. This model is constructed over time from prior experience operating in the area of interest, and can be used to estimate the lifetime of a wireless connection, given current node kinematic behaviour, and location relative to attenuating objects in the environment. This lifetime can in turn be used to evaluate Quality of Service parameters for network routes, and to select optimal routes with the longest lifetime. We propose one technique to learn about the RF propagation environment, and evaluate the utility of RF Propagation Environment Awareness.

The Marketplace of Attention: How Audiences Take Shape in a Digital Age

Feature films, television shows, homemade videos, tweets, blogs, and breaking news: digital media offer an always-accessible, apparently inexhaustible supply of entertainment and information. Although choices seems endless, public attention is not. How do digital media find the audiences they need in an era of infinite choice? In The Marketplace of Attention, James Webster explains how audiences take shape in the digital age. Webster describes the factors that create audiences, including the preferences and habits of media users, the role of social networks, the resources and strategies of media providers, and the growing impact of media measures -- from ratings to user recommendations. He incorporates these factors into one comprehensive framework: the marketplace of attention. In doing so, he shows that the marketplace works in ways that belie our greatest hopes and fears about digital media. Some observers claim that digital media empower a new participatory culture; others fear that digital media encourage users to retreat to isolated enclaves. Webster shows that public attention is at once diverse and concentrated -- that users move across a variety of outlets, producing high levels of audience overlap. So although audiences are fragmented in ways that would astonish midcentury broadcasting executives, Webster argues that this doesn't signal polarization. He questions whether our preferences are immune from media influence, and he describes how our encounters with media might change our tastes. In the digital era's marketplace of attention, Webster claims, we typically encounter ideas that cut across our predispositions. In the process, we will remake the marketplace of ideas and reshape the twenty-first century public sphere.
Entropies of weighted sums and applications to polar codes

In this note, we give some specific examples of i.i. d. random variables $X, Y$ taking values in $\mZ/n\mZ$ such that the entropy of their sum is larger than the entropy of their difference; however, we also show that this cannot happen for $n=3$. Furthermore, we show that there exist i.i. d. $\mZ$-valued random variables $X, Y$ with finite entropy such that $H(X+Y)$ can exceed $H(X-Y)$ by an arbitrarily large amount, complementing a result of Lapidoth and Pete (2008); this statement is also true for differential entropies of real-valued random variables. These results are closely related to the study of MSTD (more sums than differences) sets in additive number theory. Finally we investigate polar codes for $q$-ary input channels using non-canonical kernels to construct the generator matrix, and present applications of our results to constructing polar codes with significantly improved error probability compared to the canonical construction.

Six Weeks in the Eifel: A Case for Culture Learning during Short‐Term Study Abroad

The popularity of "short-term" 1 study abroad has grown significantly in the past decade. Today, more than half of university study abroad students choose "summer, January term, and other pro grams of 8 weeks or less" (Open Doors). In fact, such programs are cited as the driving force behind the remarkable growth in overall study abroad par ticipation, and many expect continued increase in the area of short-term programs (Loveland and Murphy). There are numerous positive aspects of short term study abroad. First, because programs typi cally take place during semester breaks, January or May intercessions, or the summer, students can study abroad without forgoing academic, extra curricular, or employment options that occur dur ing the academic year. Second, short-term pro grams typically offer courses that fulfill major, mi nor or elective requirements that students would need to take even if they remained on their home campus. Third, students can study abroad several times during their undergraduate career, and have the opportunity to learn about and explore several parts of the world. Fourth, short-term programs of fer a sense of security (Woolf), as students typically venture abroad as a group of US students and at least one faculty leader, who are often all from the same home institution. Finally, because such pro grams are typically faculty-led, there is often signifi cant control over the academic focus, course con tent, and program schedule. Based on findings from a recent ethnographic study that documented how a group of undergrad uate students defined, experienced, and perceived self-identified cultural encounters as they navi gated the complexities of the 6-week German Lan guage and Culture in Mayen program (see "Cul tural Encounters"), this article suggests that culture learning should become an integral and explicit component of short-term study abroad. After pro viding background information on the study, a model of culture leaming that can be applied to short-term study abroad is presented. Then, three issues from the study's findings that support the need for integrating culture leaming into short term study abroad are highlighted. Finally, con crete suggestions and activities are offered.
Mode Filters for Oversized Rectangular Waveguides: A Modal Approach

A semi-analytical approach, relying on the mode-matching method and the resonator technique, is proposed. It is conceived to evaluate the performance of mode filters, based on corrugations partially filled with an absorbing material, in the case of oversized rectangular waveguides. The mathematical formulation allows an accurate and fast computation of the scattering parameters, through closed-form expression of the surface integrals and some matrix algebra. The theoretical model is implemented in a code that is benchmarked against a finite-element method to elucidate its advantages with respect to volumetric solvers. After giving an insight on the physical mechanisms ruling the performance of these devices, the modal method is used to run the particle swarm optimization algorithm for different types of devices, taking advantage of the reduced computation time of the developed tool.
Discovery of a z = 6.17 galaxy from CFHT and VLT observations

Received idate? / Accepted idate? Abstract. We report the discovery of a galaxy at a redshift z = 6.17 identified from deep narrow band imaging and spectrosco pic follow-up in one of the CFHT-VIRMOS deep survey fields at 0226-04. In addition to the existing deep BVRI images of this field , we obtained a very deep narrow band image at 920 nm with the aim of detecting Lyα emission at redshift∼ 6.5. Spectroscopic follow-up of some of the candidates selected on the basis of their excess flux in the NB920 filter was performed at the VLT-UT 4 with the FORS2 instrument. For one object a strong and asymmetric emission line associated with a strong break in continuum emission is identified as Lyα at z = 6.17. This galaxy was selected from its continuum emission in the 920 nm filter rather than for its Lyα emission, in effect performing a Lyman Break detection at z = 6.17. We estimate a star formation rate of several tens of M⊙. yr −1 for this object, with a velocity dispersion ∼ 400 km.s −1 . The spectroscopic follow-up of other high z galaxy
Voice Quality Assessment and Visualization

Commercial voice analysis systems are expensive and complicated. These equipments are only available at medical centers and need to be operated by well trained physicians. Thus the treatment costs of speech disorders are usually high. To improve this situation, we develop a software system dedicated to the assessment of human voice qualities. Our system is implemented in an ordinary personal computer. High precision electronic devices are not required for acquiring and analyzing voices. Therefore, the installation costs are low. Our system relies on four voice parameters to evaluate the qualities of voice signals. These parameters are fundamental frequency, jitter, shimmer, and harmonic-to-noise ratio. These measurements are widely used in otolaryngology to assess the pitch, variation of frequency, perturbation of amplitude, and harmony of human voice. Our system extracts these information from voice data and displays them by using graphical media. Consequently, the qualities of voice are more comprehensible. Users with little training and background knowledge can operate this system in their living rooms to assess their voices.
Open-label, multicenter study of combined intrathecal morphine and ziconotide: addition of morphine in patients receiving ziconotide for severe chronic pain.

OBJECTIVE To assess the safety and efficacy of adding intrathecal morphine to intrathecal ziconotide in patients treated with stable ziconotide doses. DESIGN Multicenter, open-label study with a 4-week morphine titration phase during which ziconotide was held constant and an extension phase during which dosing of either drug could vary. SETTING Outpatient clinics. PATIENTS Patients with suboptimal pain relief receiving stable ziconotide doses (> or = 4.8 microg/day) in one of two ongoing ziconotide trials. INTERVENTIONS Ziconotide dosing remained constant during the titration phase; intrathecal morphine titration was based on each patient's daily systemic opioid dose at the study's start. During the extension phase, intrathecal ziconotide and morphine dosing were adjusted per investigator discretion. OUTCOME MEASURES Safety was assessed primarily via adverse events. Efficacy was analyzed via percentage change on the visual analog scale of pain intensity and in weekly systemic opioid consumption. RESULTS Twenty-five patients enrolled. The most common (> or = 10% of patients in either study phase) study drug-related (i.e., ziconotide/morphine combination [or ziconotide monotherapy in the extension phase only]) treatment-emergent adverse events included dizziness, peripheral edema, pruritus, and nausea. From the initial visit to week 4, visual analog scale of pain intensity scores improved by a mean of 26.3% (95% confidence interval: 15.6%-37.1%) but varied during the extension phase (mean percentage change from the initial visit ranged from -0.4% at week 16 to -35.0% at week 72). Mean percentage decrease in systemic opioid consumption from the initial visit was 49.1% at week 4 and 51.2% at week 56 of the extension phase. CONCLUSIONS Intrathecal morphine, combined with stable intrathecal ziconotide doses, reduced pain in patients with previously suboptimal pain relief on ziconotide monotherapy.
The role of expectations in human-computer interaction

This paper describes a pilot study on the role of expectations in human-computer interaction on a decision-making task. Participants (N=70) were randomly assigned to one of 5 different computer partners or to a human partner. After completing the rankings for the Desert Survival Task, participants engaged in a dialog with their computer or human partners. Results revealed that interaction with human partners was more expected and more positively evaluated than interaction with computer agents. In addition, the addition of human-like qualities to computer interfaces did not increase expectedness or evaluations as predicted. Correlation analysis for the five computer conditions demonstrated that expectations and evaluations do effect influence and perceptions of the partner. Discussion focuses on ways to coordinate expectations, interface design, and task objectives.
TROUBLE 3: A fault diagnostic expert system for Space Station Freedom's power system

Designing Space Station Freedom has given NASA many opportunities to develop expert systems that automate onboard operations of space based systems. One such development, TROUBLE 3, an expert system that was designed to automate the fault diagnostics of Space Station Freedom's electric power system is described. TROUBLE 3's design is complicated by the fact that Space Station Freedom's power system is evolving and changing. TROUBLE 3 has to be made flexible enough to handle changes with minimal changes to the program. Three types of expert systems were studied: rule-based, set-covering, and model-based. A set-covering approach was selected for TROUBLE 3 because if offered the needed flexibility that was missing from the other approaches. With this flexibility, TROUBLE 3 is not limited to Space Station Freedom applications, it can easily be adapted to handle any diagnostic system.
Interconnect mode conversion in high-speed VLSI circuits

A modification of the electromagnetic field configuration (mode conversion) at interconnect discontinuities in deep submicron digital ULSI circuits was investigated by using a full wave electromagnetic analysis. The mode conversion analysis is indispensable in identifying the signal return path, the return current distribution, and therefore for an accurate inductance modeling which remains a challenging problem. On the other hand, switching activity of a high speed CMOS circuit may produce large current derivatives. These transient currents can generate large potential surges and coupled noise due to the parasitic resistances and inductances of the wires. To this aim, we determined a simple design rule to reduce the mode conversion phenomenon and, therefore, decrease noise in high-speed ULSI circuits.

Place recognition based on Latent Dirichlet Allocation

This paper describes a new scheme based on Latent Dirichlet Allocation for place recognition of mobile robot system. It firstly extracts the local features from the training images, forms a discrete set of “image words” which are commonly known as vocabulary or codebook, and each image is represented as a frequency vector based on this vocabulary. Then the model based on Latent Dirichlet Allocation is used to learn themes distribution in the training set and testing images. Finally the unknown test images are recognized according to the similarity of themes distribution. In order to evaluate the method, we perform it on the IDOL2 Database and our own pictures. Experimental results show that the method has good robustness to different types of variations, including different illumination conditions, different perspective and other changes over long periods in real-world environments.
Statistical mechanics analysis of LDPC coding in MIMO Gaussian channels

Using analytical methods of statistical mechanics, we analyse the typical behaviour of a multiple-input multiple-output (MIMO) Gaussian channel with binary inputs under low-density parity-check (LDPC) network coding and joint decoding. The saddle point equations for the replica symmetric solution are found in particular realizations of this channel, including a small and large number of transmitters and receivers. In particular, we examine the cases of a single transmitter, a single receiver and symmetric and asymmetric interference. Both dynamical and thermodynamical transitions from the ferromagnetic solution of perfect decoding to a non-ferromagnetic solution are identified for the cases considered, marking the practical and theoretical limits of the system under the current coding scheme. Numerical results are provided, showing the typical level of improvement/deterioration achieved with respect to the single transmitter/receiver result, for the various cases.
Happiness and meaning in life: Unique, differential, and indirect associations with mental health

ABSTRACT Researchers broadly recognize happiness and meaning in life as key indicators of hedonic and eudaimonic well-being respectively. Although happiness and meaning in life are life pursuits among many people, they might differ in their associations with mental health. Taking both a preventative and promotive approach (Wong, 2013), this study examined the relations of happiness and meaning in life with mental health using a university student sample (N = 284). Happiness and meaning in life were both uniquely, negatively related to perceived stress as well as anxiety and depressive symptoms, although happiness was more strongly linked to these mental health outcomes. Additionally, happiness and meaning in life were both indirectly related to anxiety and depressive symptoms through their positive association with perceived stress. Based on our findings and previous literature, we propose the following distinction between happiness and meaning in life: the former leads to self-satisfying outcomes and the latter yields self-transcending outcomes. We propose that the overlap between the two constructs result in salutary outcomes, reflecting the emphasis of Positive Psychology 2.0 on the complexity of meaning in life and the intricate link between positive and negative psychological processes. Implications for counseling are discussed.
Radio continuum sources associated with ab aur

We present high angular resolution, high-sensitivity Very Large Array observations at 3.6 cm of the Herbig Ae star AB Aur. This star is of interest since its circumstellar disk exhibits characteristics that have been attributed to the presence of an undetected low mass companion or giant gas planet. Our image conrms the continuum emission known to exist in association with the star, and detects a faint protuberance that extends about 0. 00 3 to its SE. Previous theoretical considerations and observational results are consistent with the presence of a companion to AB Aur with the separation and position angle derived from our radio data. We also determine the proper motion of AB Aur by comparing our new observations with data taken about 17 years ago and nd values consistent with those found by Hipparcos.
Assessment of ventricular-arterial coupling with a model-based sensor

Estimation of ventricular contractility is clinically important in diagnosing cardiac dysfunction in the critically ill. However, experimental assessment of indexes of ventricular contractility, such as the end-systolic pressure-volume relationship requires a highly invasive maneuver. This research describes the use of a previously validated cardiovascular system (CVS) model and identification process to evaluate the right-ventricle contractility as well as the right ventricular arterial coupling in septic shock. The results show good agreement with the gold-standard experimental assessment (conductance catheter method), and offer the potential to develop a model-based sensor to monitor the coupling in clinical realtime.
Nonlinear timing jitter in an installed fiber network with balanced dispersion compensation

We present field measurements of timing jitter induced by intrachannel cross-phase modulation on an installed terrestrial fiber link. The measured jitter is strongly dependent on the arrangement of dispersion-compensating fiber, in excellent qualitative agreement with numerical simulations. We find that balancing the dispersion compensation yields significant benefits, even for an inhomogeneous fiber path. We show that numerical simulation combined with experimental results is a practical way to develop a link model, even when the system loss cannot be completely characterized experimentally.
