Intelligent Mobile Location in Wireless Networks Ph

Wireless communication systems, both cellular and distributed multi-hop networks, require efficient utilization of scarce radio bandwidth and energy consumption costs. It is proposed to develop intelligent mobile location algorithms that utilize probabilistic estimates in order to minimize these costs. For cellular wireless systems, sequential paging algorithms have been developed for various delay constraints. These algorithms typically group the possible locations in some manner and page them in decreasing order of user location probability. The design and analysis of such algorithms for cellular networks, and their extension to distributed multi-hop situations will be the chief subject of the proposed thesis. A related topic to be explored is the accurate estimation of mobile location probabilities using Bayesian techniques. Further, mobility models will be developed in order to simulate these estimation and location algorithms under realistic settings.
Symbolic Simulation of the Propagation and Filtering of Transient Faulty Pulses

This paper is concerned with statically analyzing the susceptibility of arbitrary combinational circuits to single event upsets that are becoming a significant concern for reliability of commercial electronics. For the first time, a fast and accurate technique based on static, vector-less analysis of soft error rates (SER) in general combinational circuits is proposed. The analysis technique is targeted to cell-based designs and characterized by two essential features: (1) accurate error-pulse propagation and attenuation models of library cells that are based on STAlike pre-characterization methods; and (2) an efficient computational procedure for pulse propagation via encoding of the error-pulses with the binary decision diagrams (BDD). Both electrical and logical masking mechanisms of soft errors are accurately captured.
Educating for conscious awareness

Conscious awareness implies a connection with all of life. Being conscious means acting with more intention, having greater self‐regulating behaviour, and demonstrating a deeper awareness of the causes and consequences of actions. This paper describes a course design for the development of consciousness awareness in management education. The purpose of the course, Managing with Spirit, is to encourage students to be more aware of their relationships with themselves, their community, and the planet as integrated wisdom. The three sections of the course (inner leadership, spirit at work, and the science of interconnection) all contribute to developing practices of reflection, mindfulness, and presencing for deeper awareness. From this, students can bring significant skills into the organizational context that include improved interpersonal skills, creativity, adaptability, problem‐solving, leadership skills, compassion, and ecological awareness. These skills enable our future managers to be better equipped to deal with the increasingly complex issues that are facing organizations as they understand and appreciate the sacredness of our interconnection with each other and our planet.
Extending INET framework for directional and asymmetrical wireless communications

This paper reports our work on extending the OMNeT++ INET Framework with a directional radio model, putting a special emphasis on the implementation of asymmetrical communications. We first analyze the original INET radio model, focusing on its design and components. Then we discuss the modifications that have been done to support directional communications. Our preliminary results show that the new model is flexible enough to allow the user to provide any antenna pattern shape, with only an additional reasonable computational cost.
Discrepancy Between Definitions of Learning Disabilities and School Practices

Students referred by general education teachers to school study teams (SSTs) were evaluated for learning disabilities (LD) eligibility. We classified children as LD on the basis of a WISC-III Full Scale IQ of 82 or higher and a 22-point discrepancy between IQ and any WRAT-R achievement score. Research decisions were then contrasted with actual school-based decisions regarding the child as LD. Over half of the students referred to SSTs were certified by the schools as LD, yet less than half of these school-certified students with LD evidenced the aptitude-achievement discrepancy required by the state. Examination of the cases called LD by the schools revealed that children were classified as LD on the basis of low absolute achievement, regardless of whether or not a discrepancy existed. Moreover, in cases where a discrepancy was found but the school did not classify the child as LD, that child evidenced significantly higher achievement, despite exhibiting the requisite 22-point discrepancy. The school-identified students with LD constituted an extremely heterogeneous group, including students with mental retardation along with a substantial number who failed to qualify for any special education services. Findings are discussed in terms of the discrepancy between criteria specified in state regulations and what the committee members at the school site seemed to use in classifying children with LD.
Anticonvulsant Effects of Transcranial Direct‐current Stimulation (tDCS) in the Rat Cortical Ramp Model of Focal Epilepsy

Summary: Purpose: Weak direct currents induce lasting alterations of cortical excitability in animals and humans, which are controlled by polarity, duration of stimulation, and current strength applied. To evaluate its anticonvulsant potential, transcranial direct current stimulation (tDCS) was tested in a modified cortical ramp‐stimulation model of focal epilepsy.
Comparitive Analysis of Conventional, Real and Complex Wavelet Transforms for Iris Recognition

Iris Recognition System is a process of recognizingan individual by analyzing the random pattern of iris and comparing with database. In this paper comparative analysis is perform with wavelet transform such as 2D Discrete wavelet transform (2D-DWT), Real dual tree Discrete wavelet transform (R-DT-DWT) and Complex dual tree Discrete wavelet transform (C-DT-DWT) for iris recognition. These approaches are tested on various databases. The process starts from pre-processing. In pre-processing stage the image is enhanced, segmented and normalized. Now smoothed image is taken into consideration for feature extraction using above mentioned wavelet transforms. Finally image is applied post-classifier for reducing false
Research Commentary: On Gap Gazing in Mathematics Education: The Need for Gaps Analyses

Analyses of disparities in students' mathematics experiences and outcomes are an essential part of efforts to promote equity. Scholars concerned about equity should not write off such analyses as mere “gap gazing. ” Research on gaps between underserved groups and their more advantaged peers are important for shaping public opinion and informing education policy. Analyses of gaps also inform mathematics education research and practice, illuminating which groups and curricular areas are most in need of intervention and additional study. Instead of pulling back from gaps analyses, the mathematics education community should move toward more skilled and nuanced analyses and integrate research on instructional reforms with careful analyses of their impact on disparities in student outcomes broadly defined.
Uber: Utilizing Buffers to Simplify NoCs for Hundreds-Cores

Approaching ideal wire latency using a network-on-chip (NoC) is an important practical problem for many-core systems, particularly hundreds-cores. Although other researchers have focused on optimizing large meshes, bypassing or speculating router pipelines, or creating more intricate logarithmic topologies, this paper proposes a balanced combination that trades queue buffers for simplicity. Preliminary analysis of nine benchmarks from PARSEC and SPLASH using execution-driven simulation shows that utilization rises from 2% when connecting a single core per mesh port to at least 50%, as slack for delay in concentrator and router queues is around 6x higher compared to the ideal latency of just 20 cycles. That is, a 16-port mesh suffices because queueing is the uncommon case for system performance. In this way, the mesh hop count is bounded to three, as load becomes uniform via extended concentration, and ideal latency is approached using conventional four-stage pipelines for the mesh routers together with minor logarithmic edges. A realistic Uber is also detailed, featuring the same performance as a 64-port mesh that employs optimized router pipelines, improving the baseline by 12%. Ongoing work develops techniques to better balance load by tuning the placement of cache blocks, and compares Uber with bufferless routing.
Structure analysis of free and bound states of an RNA aptamer against ribosomal protein S8 from Bacillus anthracis

Several protein-targeted RNA aptamers have been identified for a variety of applications and although the affinities of numerous protein-aptamer complexes have been determined, the structural details of these complexes have not been widely explored. We examined the structural accommodation of an RNA aptamer that binds bacterial r-protein S8. The core of the primary binding site for S8 on helix 21 of 16S rRNA contains a pair of conserved base triples that mold the sugar-phosphate backbone to S8. The aptamer, which does not contain the conserved sequence motif, is specific for the rRNA binding site of S8. The protein-free RNA aptamer adopts a helical structure with multiple non-canonical base pairs. Surprisingly, binding of S8 leads to a dramatic change in the RNA conformation that restores the signature S8 recognition fold through a novel combination of nucleobase interactions. Nucleotides within the non-canonical core rearrange to create a G-(G-C) triple and a U-(A-U)-U quartet. Although native-like S8-RNA interactions are present in the aptamer-S8 complex, the topology of the aptamer RNA differs from that of the helix 21-S8 complex. This is the first example of an RNA aptamer that adopts substantially different secondary structures in the free and protein-bound states and highlights the remarkable plasticity of RNA secondary structure.
Phase Relations of Harzburgite and MORB up to the Uppermost Lower Mantle Conditions: Precise Comparison With Pyrolite by Multisample Cell High‐Pressure Experiments With Implication to Dynamics of Subducted Slabs

We determined phase relations of harzburgite and basalt (mid‐ocean ridge basalt, MORB) at 12–28 GPa and 1600–2200 °C with a large number of experiments using a multianvil high‐pressure apparatus. These phase relations were precisely compared with those of pyrolite simultaneously determined by multisample cell technique. The post‐spinel (pSp) transition of harzburgite occurs at 23 GPa and 1600 °C with the boundary slope of −3 ± 1 MPa/°C. The post‐garnet (pGt) transition boundary of MORB, defined as the beginning of the majorite garnet‐bridgmanite transition, is located at 25 GPa and 1600 °C, with a slope of 1.5 ± 1 MPa/°C. The pSp transition of harzburgite occurs at higher pressure by 0.5 GPa at 1600 °C and has the more negative slope than that of pyrolite (−1 ± 1 MPa/°C). The pGt transition of MORB occurs at higher pressure by 3 GPa than the pSp transition of harzburgite. At 1600 °C, the density of pyrolite is smaller than those of harzburgite and MORB before the pSp transition of pyrolite (pyrolite–harzburgite/MORB = −0.17 g/cm3). After the pSp transition of pyrolite, harzburgite has lower densities than that of pyrolite at 22–27 GPa (pyrolite–harzburgite = 0.31 and 0.08 g/cm3 before/after the pSp transition in harzburgite, respectively). On the other hand, the density of MORB becomes the highest among the three rocks above 25 GPa after the pGt transition of MORB (pyrolite–MORB = −0.18 g/cm3). The present density contrasts suggest that harzburgite and MORB may stagnate and accumulate in the transition zone by slab subduction, resulting in that the pyrolitic part of slabs is subducted into the lower mantle.
Shoplifter Perceptions of Store Environments: An Analysis of how Physical Cues in the Retail Interior Shape Shoplifter Behavior

Shoplifting losses and resulting violence and disruption continue to plague retail stores across the globe. Environmental criminology problem-solving process includes interviewing offenders involved in specific crimes in order to construct and evaluate crime control countermeasures. Using rational choice perspective and situational crime prevention process as theoretical frameworks, the authors applied both content and narrative analyses to interviews with known and admitted shoplifting offenders in order to identify in-store situational (physical) cues for crime prevention planning. Results revealed that over 70% of offender observations fell into four categories: hardened targets, natural surveillance, extended guardianship, and formal surveillance.
LTE - Wi-Fi coexistence in 5 GHz band

The proliferation of smart phones combined with increasing mobile data demand, cellular network operators around the world are considering various ways to augment network capacity. To meet the projected 1000x increase capacity by 2020 [3], a holistic approach is needed. The proposed solutions include hyper-dense small cell deployment, intelligent utilization of existing spectrum and offloading to other networks like Wi-Fi. Extending the LTE-Advanced (LTE-A) to unlicensed spectrum is a new approach being considered by the global standards body 3GPP, as part of LTE Release-13. The feasibility of LTE operation in 5 GHz band, also known as Licensed Assisted Access (LAA), is being studied. The main challenge is to ensure LTE do not affect the performance of existing technologies/systems in this band such as Wi-Fi, Radar etc. In this paper, we provide simulation study on LTE - Wi-Fi coexistence in the unlicensed spectrum.
Comparative Study of Iterative Channel Estimation Schemes for Turbo Decoding with Antenna Diversity Reception in Rayleigh Fading

SUMMARY Turbo decoding with coherent detection requires accurate channel estimation. In this paper, we consider outer-turbo channel estimation (OTCE), which carries out iterative channel estimation before turbo decoding, and inner-turbo channel estimation (ITCE), which incorporates iterative channel estimation into turbo decoding process. The average bit error rate (BER)performances with OTCE and ITCE in a frequency nonselective Rayleigh fading channel with antenna diversity reception are evaluated by means of computer simulations to be compared. It is found that although ITCE is superior to OTCE, OTCE provides the average BER performance very close to ITCE when dual antenna diversity reception is used.
Reduced cortical thickness and increased gyrification in generalized anxiety disorder: a 3 T MRI study

Abstract Background Although the study of the neuroanatomical correlates of generalized anxiety disorder (GAD) is gaining increasing interest, up to now the cortical anatomy of GAD patients has been poorly investigated and still no data on cortical gyrification are available. The aim of the present study is to quantitatively examine the cortical morphology in patients with GAD compared with healthy controls (HC) using magnetic resonance imaging (MRI). To the best of our knowledge, this is the first study analyzing the gyrification patterns in GAD. Methods A total of 31 GAD patients and 31 HC underwent 3 T structural MRI. For each subject, cortical surface area (CSA), cortical thickness (CT), gray matter volume (GMV), and local gyrification index (LGI) were estimated in 19 regions of interest using the Freesurfer software. These parameters were then compared between the two groups using General Linear Model designs. Results Compared with HC, GAD patients showed: (1) reduced CT in right caudal middle frontal gyrus (p < 0.05, Bonferroni corrected), (2) hyper-gyrification in right fusiform, inferior temporal, superior parietal and supramarginal gyri and in left supramarginal and superior frontal gyri (p < 0.05, Bonferroni corrected). No significant alterations in CSA and GMV were observed. Conclusions Our findings support the hypothesis of a neuroanatomical basis for GAD, highlighting a possible key role of the right hemisphere. The alterations of CT and gyrification in GAD suggest a neurodevelopmental origin of the disorder. Further studies on GAD are needed to understand the evolution of the cerebral morphology with age and during the clinical course of the illness.
Visual odometry aided by a sun sensor and inclinometer

In this paper, we present a novel approach to localization for planetary rovers, in which sun sensor and inclinometer measurements are incorporated directly into a stereo visual odometry pipeline. Utilizing the absolute orientation information provided by the sun sensor significantly reduces the error growth of the visual odometry path estimate. The measurements have minimal computation, power, and mass requirements, providing a localization improvement at nearly negligible cost. We describe the mathematical formulation of error terms for the stereo camera, sun sensor, and inclinometer measurements, as well as the bundle adjustment framework for determining the maximum likelihood vehicle transformation. Improved localization accuracy is demonstrated through extensive experimental results from a 10 kilometre traversal of a Mars analogue site on Devon Island in the Canadian High Arctic.
Temporal integration for on-board stereo-based pedestrian detection

Pedestrian detection is a difficult task for the following reasons. Firstly, pedestrians have many variations of size, pose, clothing, and motion. Secondly, the background tends to be crowded. Thirdly, many pedestrian-like patterns are observed in real environments. As a result, even if state-of-the-art pattern recognition method is used, a frame-by-frame detection has many false positives and negatives. This article presents a method of temporal integration for stereo-based pedestrian detection for improving the detection performance. In our method, a pedestrian is detected by evaluating consistency of the extracted pedestrian candidate for a short period of time. In order to get the consistency, the pedestrian candidate at each frame is combined with temporally corresponded ones through a hypothesis selection process. We demonstrate the effectiveness of our method by checking a recall and false positive number with 20,000 frames recorded in complex urban environments and public data sets. The proposed method reduces the number of false detection to one hundredth with holding recall.
A Criação de Amigos Imaginários: Uma Revisão de Literatura

Pretend play is an important milestone in child development. Among the many forms that symbolic play can take, one stands out for its singularity: the creation of imaginary companions. The phenomenon has been associated with various positive aspects of development, however, there are very few Brazilian studies investigating this topic. The present research aims to contribute to this study field by presenting a systematic literature review on imaginary companions. The literature review was based on the analysis of indexed books and articles found in SciELO-Brasil, Index Psi, PePSIC, LILACS and PsycINFO databases, published between 1934 and 2013. In total, 46 national and foreign papers, published between 1934 and 2013, were found. The literature suggests that the creation of imaginary companions is associated with important gains, for example, in creativity, sociability and social cognition. Therefore, future directions for this line of research in the country are suggested.
Coalitional game theoretic optimization of electricity cost for communities of smart households

In this paper we propose a novel coalitional game theory based optimization method for minimizing the cost of the electricity consumed from the power grid by a community of smart households. A smart household may own both a renewable energy source and an energy storage system (ESS), or only an ESS. We propose an optimization model in which all the members of the community jointly share their renewable resources and storage systems. We show that the proposed coalitional optimization method reduces the consumption costs both at community level and at the individual level when compared to the case in which the households would individually optimize their costs. The monetary revenues gained by the coalition are divided among the members of the coalition according to the Shapley value. Simulation examples show that the proposed coalitional optimization method may reduce the electricity costs for the community by roughly 18%.
Role recognition for meeting participants: an approach based on lexical information and social network analysis

This paper presents experiments on the automatic recognition of roles in meetings. The proposed approach combines two sources of information: the lexical choices made by people playing different roles on one hand, and the Social Networks describing the interactions between the meeting participants on the other hand. Both sources lead to role recognition results significantly higher than chance when used separately, but the best results are obtained with their combination. Preliminary experiments obtained over a corpus of 138 meeting recordings (over 45 hours of material) show that around 70% of the time is labeled correctly in terms of role.
Merging the Bramble-Pasciak-Steinbach and the Crouzeix-Thomée criterion for H1-stability of the L2-projection onto finite element spaces

Suppose S ⊂ H1(Ω) is a finite-dimensional linear space based on a triangulation T of a domain Ω, and let Π : L2(Ω) → L2 (Ω) denote the L2-projection onto S. Provided the mass matrix of each element T ∈ T and the surrounding mesh-sizes obey the inequalities due to Bramble, Pasciak, and Steinbach or that neighboring element-sizes obey the global growth-condition due to Crouzeix and Thomee, Π is H1-stable: For all u ∈ H1 (Ω) we have ||Πu||H1 (Ω) ≤ C ||u||H1 (Ω) with a constant C that is independent of, e.g., the dimension of S.This paper provides a more flexible version of the Bramble-Pasciak-Steinbach criterion for H1-stability on an abstract level. In its general version, (i) the criterion is applicable to all kind of finite element spaces and yields, in particular, H1-stability for nonconforming schemes on arbitrary (shape-regular) meshes; (ii) it is weaker than (i.e., implied by) either the Bramble-Pasciak-Steinbach or the Crouzeix-Thomee criterion for regular triangulations into triangles; (iii) it guarantees H1-stability of Π a priori for a class of adaptively-refined triangulations into right isosceles triangles.
Radiation from an Eccentric Coated Cylinder with Slots of Arbitrary Sizes and Positions

The transverse electric (TE) field patterns and characteris- tics are considered for a cylinder with N infinite axialslots of arbitrary opening size and position. The cylinder is a thin circular conductor and covered by an eccentric material. Radiations are determined by applying the boundary conditions to the cylindrical wave functions of the fields. The addition theorem of Bessel functions is employed to find an infinite-series solution in Fourier-Bessel series form. Results are achieved by reducing the produced infinite series to a finite num- ber of terms and judged against other published data. Numerical and graphical results for different values are also presented and discussed for small eccentricities.
