Stochastic Model for the NLMS Algorithm with Correlated Gaussian Data

This paper proposes a new stochastic model for the normalized LMS (NLMS) algorithm under correlated input data. The proposed model is derived without invoking the simplifying assumption that xT(n)x(n) has a chi-square distribution to determine E{1/[x T(n)x(n)/N]}. Under correlated input data that assumption is not correct and thus the resulting model becomes inaccurate. Without considering such simplifying assumption, a high-order hyperelliptic integral has to be computed. The proposed model is based on tackling the solution of that integral. Numerical simulations verify the quality of the proposed model
Texture Classification Based on Random Threshold Vector Technique

A new feature set derived from the fractal geometry, called the random threshold vector (RTV) is proposed for texture analysis. The RTV is computed for different run length entropy dimensions. The run length entropy dimensions are calculated based on different thresholds. To test the rotationally invariant feature, the run length entropies are calculated in different directions. The experimental results show that the RTV contains great discriminatory information needed for a successful classification.
A computational investigation and the conformational analysis of dimers, anions, cations, and zwitterions of L‐phenylalanine

The structure and stability of various conformations of L‐phenylalanine (PheN) and its zwitterions (PheZ), along with their ionized counterparts, cation (PheC) and anion (PheA), generated by adding and removing a proton respectively, have been investigated using first principle calculations in vacuum and in solution. This is followed by an extensive study on various possible dimer (PheD) conformations, which are noncovalently bound units without a peptide bond. This study results in 52, 31, 12, 9, and 11 minimum energy structures on the potential energy surfaces of PheD, PheN, PheC, PheA, and PheZ, respectively. Several important nonbonded interactions such as hydrogen bonds, NH‐π, CH‐π, OH‐π, and π‐π interactions, which impart stability to the monomeric and dimeric units, have been analyzed. The capability and strength of the nonbonded interactions drastically changing the conformational orientations of monomeric units has been illustrated. © 2011 Wiley Periodicals, Inc.

Backpressure-based Routing and Congestion Control Protocols for Delay Tolerant Networks

In this paper we suggest a novel routing algorithm for Delay Tolerant Networks (DTN). The suggested backpressurealgorithm uses information about queue backlogs in order to make routing decisions on a per-packet basis without the notion of end-to-end routes. The backpressure approach is highly agile and can be used as both a stand alone routing algorithm and a congestion control algorithm for well-known routing protocols. We have demonstrated performance analysis and implemented the suggested algorithms in a DTN environment using the ONE simulator. Using the simulation, we compared our new routing algorithm with other well-known algorithms (Epidemic, Prophet, MaxProp, and Spray and Wait). The main outcome of the simulation shows a significant improvement in energy consumption while sustaining the delivery ratio. To the best of our knowledge, this is the first ever discussion and implementation of dynamic backpressure routing in DTNs.
Vector generation for power supply noise estimation and verification of deep submicron designs

This paper presents new techniques for generating a small set of patterns for power network simulation to estimate the maximum power supply noise of the chip, as well as to identify cells/blocks for which the power supply noise at their V/sub dd/ ports exceeds a specified threshold. We first present an efficient, cell-level simulator for estimating power supply noise of any given vectors. Based on this simulator, we then apply the genetic algorithm (GA) to derive a small set of patterns producing high power supply noise. To identify critical nodes with power supply noise exceeding a threshold, the multiobjective GA is adapted for pattern generation. To achieve high coverage of such critical nodes, we model the search criteria as the maximum weighted matching of a bipartite graph, and guide the search direction according to the matching results. The derived patterns will be simulated on a power network simulator to obtain a lower bound of the maximum power supply noise and to identify the critical nodes. Experimental results on public benchmark circuits, as well as some industrial designs, are presented to demonstrate the efficiency and effectiveness of the proposed approaches.
Towards automatic assessment and mapping of traffic infrastructure by adding vision capabilities to a geoinformation inventory

We consider geoinformation inventory systems containing locations and types of traffic signs and road surface markings in a given geographical region. Such systems allow a human operator to assess the current state of the traffic infrastructure by comparing a recent georeferenced video with the prescribed state stored in the inventory. We are concerned with automating this assessment procedure (as well as the initial creation of the inventory) by designing appropriate computer vision modules. In this paper, we briefly present our research project, provide a review of suitable computer vision techniques, and present in more details two techniques which proved most promising in preliminary experiments. The two presented techniques are traffic sign detection by boosted Haar wavelets, and enhancement of surface markings by applying steerable filters to suitably preprocessed images. The experiments have been performed on individual real images acquired from a moving vehicle by a single perspective camera. The obtained results are provided and discussed.
Estimating the distribution of economy activity : a case study in Jiangsu Province ( China ) using large scale social network data

Understanding the spatial distribution of human social-economic activities helps marketing, policy making, planning, and government management. With rapid growing of internet, communication technology and the high penetration of mobile phones, massive activity data is collected from people daily life, giving us an opportunity to estimate the national distribution of human activities. This paper proposed a human-sensing approach to estimate the spatial distribution of economic activity derived from the mass of human mobility data. Comparisons with the economic activity estimation method based on a remote-sensing technology (i.e., nighttime light imagery) are analyzed. The results indicated that human mobility and activity data is a good indicator to model the high-resolution economic activity.

Non-linear observer for slip estimation of skid-steering vehicles

Accurate estimation of slip is essential in developing autonomous navigation strategies for mobile vehicles operating in unstructured terrain. In this paper, a sliding mode observer is firstly constructed to estimate slip parameters based on the kinematics model of a skid-steering vehicle and trajectory measurement. The stability of the sliding mode observer is given in a mathematical context. Slip estimation schemes using an extended Kalman filter and direct mathematical inversion of the kinematic equations are also presented for comparison purposes. It is shown that the non-linear sliding mode observer is more accurate than the other two methods. The robustness and superior performance of the sliding mode observer is demonstrated using both simulation and experimental results. A camera based system is used to measure the vehicle trajectory during experimental validation

The role of community context and psychological well-being for physical health: A dyadic study of military couples

ABSTRACT Drawing from the social organizational theory of community action and change (SOAC) within a systemic biopsychosocial perspective, associations between community context (military community connections and satisfaction with military life), psychological well-being (depressive symptoms, anxiety, and self-efficacy), and physical health were examined for a sample of active duty service members and their civilian spouses (N = 236 couples) using an actor partner interdependence framework. Service members with higher levels of military community connections reported better psychological well-being. When civilian spouses were more satisfied with military life, both partners reported better psychological well-being. In turn, both spouses’ psychological well-being was related to their own reports of physical health. Statistically significant indirect effects were found between community contexts and spouses’ physical health. Enhancing community connections may be an important leverage point for supporting health and family readiness.
Introduction to Query Processing and Optimization

Query Processing is the scientific art of obtaining the desired information from a database system in a predictable and reliable fashion. Database systems must be able to respond to requests for information from the user i.e. process queries. In large database systems, which may be running on un-predictable and volatile environments, it is difficult to produce efficient database query plans based on information available solely at compile time. Getting the database results in a timely manner deals with the technique of Query Optimization. Efficient processing of queries is an important requirement in many interactive environments that involve massive amounts of data. Efficient query processing in domains such as the Web, multimedia search, and distributed systems has shown a great impact on performance. This paper will introduce the basic concepts of query processing and query optimization in the relational database. We also describe and difference query processing techniques in relational databases.
Liensinine- and Neferine-Induced Cardiotoxicity in Primary Neonatal Rat Cardiomyocytes and Human-Induced Pluripotent Stem Cell-Derived Cardiomyocytes

Due to drug-induced potential congestive heart failure and irreversible dilated cardiomyopathies, preclinical evaluation of cardiac dysfunction is important to assess the safety of traditional or novel treatments. The embryos of Nelumbo nucifera Gaertner seeds are a homology of traditional Chinese medicine and food. In this study, we applied the real time cellular analysis (RTCA) Cardio system, which can real-time monitor the contractility of cardiomyocytes (CMs), to evaluate drug safety in rat neonatal CMs and human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs). This study showed detailed biomechanical CM contractility in vitro, and provided insights into the cardiac dysfunctions associated with liensinine and neferine treatment. These effects exhibited dose and time-dependent recovery. Neferine showed stronger blocking effect in rat neonatal CMs than liensinine. In addition, the effects of liensinine and neferine were further evaluated on hiPS-CMs. Our study also indicated that both liensinine and neferine can cause disruption of calcium homeostasis. For the first time, we demonstrated the potential cardiac side effects of liensinine or neferine. While the same inhibition was observed on hiPS-CMs, more importantly, this study introduced an efficient and effective approach to evaluate the cardiotoxicity of the existing and novel drug candidates.
MadCache: A PC-aware Cache Insertion Policy

While the field of computer architecture is always looking for novel research directions to bring improved performance and efficiency, it is often simple improvements to more mature topics that have the most substantial impact. Cache replacement policy is one such research area, where innovations are highly sought after because of their direct improvement on performance. Furthermore, as chip-multiprocessors have become the dominant chip design, new cache replacement schemes should seek to improve the performance of workloads for both singlethreaded and shared cache multithreaded systems. In this paper we propose MadCache, a cache insertion policy that uses memory access history based on the Program Counter (PC) to determine the appropriate policy for the L3 cache. A PC-based history table stores information regarding cache accesses and determines whether the L3 should default to the LRU replacement policy for workloads that exhibit good locality or bypass for streaming memory accesses. Furthermore, this PC-based history table allows individual PCs to override this default policy if its history indicates a behavior significantly different from the typical trend of the workload. We show that MadCache is able to improve IPC by 2.5% over LRU for a singlethreaded 1MB 16-way L3 cache. Finally, we extend MadCache to a four thread, 4MB shared L3 cache and demonstrate a 6% improvement in throughput and 4.5% speedup over LRU averaged across the mixed benchmarks we tested.

A Provably Secure Parallel Certificatelesss Ring Signcryption Scheme

Ring signcryption is a cryptographic primitivewhich combines the functions of a ring signature scheme andan encryption scheme. It can provide confidentiality, anonymityand authenticity simultaneously. In this paper, we show asecurity flaw in a previous certificateless ring signcryptionscheme (Wang et al.’s scheme) and propose an efficient parallelring signcryption scheme in certificateless public key setting.Compared with Wang et al.’s scheme, our new scheme needs 3less pairings and enjoys a shorter ciphertext. Furthermore theparallel execution of the expensive signature and encryptionoperations in our scheme implies a gain in running efficiency.We also prove that the new scheme is not only indistinguishableagainst chosen-ciphertext attacks but also existentially unforgeableagainst chosen-message attacks.
Estimating phase-locked loop jitter due to substrate coupling: a cyclostationary approach

On-chip phase-locked loops (PLLs) are critical components for clock generation and recovery in high-speed communication and data processing systems. The presence of partially-correlated substrate noise presents a new challenge to predicting PLL jitter. We propose a model that describes the substrate noise-to-jitter transfer characteristics for CMOS ring oscillator-based PLLs on epitaxial substrates. The proposed model is verified against jitter simulations.
Transcending the theory-practice problem of technology

: Design activities are fundamental to technological progress. Current design research holds tight to positivism, abandoned and critically opposed to by philosophers, mostly those outside the U.S. Maintaining the positivist view when conducting research leads to significant deficiencies in the quality of research, and to problems in transferring research results to practice. In spite of significant research efforts, the improvement of practice is slow. This improvement, in turn, does not necessarily reflects the diffusion of research results into practice, but rather, the development of ideas by practitioners. This paper analyzes this theory-practice problem of technology from practical, cultural, and philosophical perspectives. It proposes a research methodology of design and briefly shows how this methodology can shed light on some problems related to technology. The paper also discusses the fundamental role of design in technology, thereby viewing the research methodology proposed as a methodology for studying some aspects of technology.
Asymptotic design and analysis of multistage detectors with unequal powers

In this work we provide equations to precisely calculate the asymptotic weighting of multistage detectors satisfying the individually and jointly LMMSE criteria in the projection subspace for scenarios with unequal powers. Additionally, a general expression of the SINR achievable at the filter output as system size grows large is derived. Such an equation can be applied to any multistage detector. We specialize this result to both the individually and jointly LMMSE multistage detector with asymptotic weighting. We show that the individually LMMSE detector outperforms the other detector in the case of unequal received powers while both the detectors are equivalent in the case of equal received powers.
Grade Level Differences in the Cognitive, Behavioral, and Physiological Components of Test Anxiety

The capacity to cope with test anxiety that contain high concentrations of cognitive, behavioral, and physiological manifestations, is becoming increasingly important in educational contexts as well as evaluative settings. The developing ability to deal with test anxiety relative to the increasingly strict evaluative practices students encounter points that students’ test anxiety may decline as they move through school years. This study examined three test anxiety components (thoughts, off-task behaviors, and autonomic reactions) with students from 3 public schools in İstanbul, Turkey. Using a diverse sample of elementary (Grade 4; N = 414) and middle (Grade 6; N = 201) school students, grade level differences in these components were investigated. Applying a multivariate approach, significant differences were found in the overall test anxiety, favoring fourth grade students. The results also revealed Grade 4 advantage for off-task behaviors and autonomic reactions, = . 014 and = . 011, but no grade level differences in the thoughts. Educational implications of the findings are discussed.
DFG reference number and title

The four types of nouns to be distinguished are sortal nouns (SC), individual nouns (IC), relational nouns proper (RC), and functional nouns (FC) (cf. Löbner 1979, 1985). The four types differ along two independent semantic parameters: relationality and inherent uniqueness. These characteristics are immediately relevant for the way in which the respective nouns are used: • IC and FC nouns are inherently unique; they are therefore in their unmarked uses combined with definite determination and in the singular. • SC and RC nouns do not determine semantically the number of their potential referents in a given context: they may apply to zero, one or multiple instances; they are therefore open for singular and plural use. The unmarked use is indefinite. • RC and FC nouns are inherently relational. They therefore require the specification of their possessor argument for determining their referents in a given context.

Fuzzy Thresholding in Wavelet Domain for Speckle Reduction in Synthetic Aperture Radar Images

Aperture Radar (SAR) imagery has improved despeckling performance. To deduce the problem of filtering the multiplicative noise to the case of an additive noise, the wavelet decomposition is performed on the logarithm of the image gray levels. The detail coefficients produced by the bidimensional discrete wavelet transform (DWT-2D) needs to be thresholded to extract out the speckle in highest subbands. An initial threshold value is estimated according to the noise variance. In this paper, an additional fuzzy thresholding approach for automatic determination of the rate threshold level around the traditional wavelet noise thresholding (initial threshold) is applied, and used for the soft or hard-threshold performed on all the high frequency subimages. The filtered logarithmic image is then obtained by reconstruction from the thresholded coefficients. This process is applied a single time, and exclusively to the first level of decomposition. The exponential function of this reconstructed image gives the final filtered image. Experimental results on test images have demonstrated the effectiveness of this method compared to the most of methods in use at the moment.
Performance Analysis of Primary User Detection in a Multiple Antenna Cognitive Radio

We consider the problem of detecting a primary user signal over a wireless channel by a cognitive radio with multiple antennas. We present a multiple antenna processing based energy detector. In this detection method, the multiple copies of the primary user signal at the antennas of the cognitive radio receiver are combined and input to an energy detector. We consider two multiple antenna processing methods and analyze their detection performance - the achieved probability of detection for a pre-specified probability of false alarm and given signal-to-noise ratio. We derive closed-form expressions for the probabilities for detection and false alarm for each of the processing schemes. Finally, we show through numerical results the potential improvement in primary user detection with multiple antenna processing based energy detection at the cognitive radio receiver.
