Real-Time Software Receiver for GPS Controlled Reception Pattern Antenna Array Processing

This paper demonstrates a real-time software receiver supporting GPS L1 C/A controlled reception pattern antenna (CRPA) processing. The software receiver is implemented on a widely-available recent generation multi-core processor and is capable of processing array signals from either radio frequency (RF) front-end modules or collected datasets. Most importantly, the receiver allocates dedicated satellite-tracking antenna patterns for each baseband receiver channel. The architecture of such a software receiver needs to be carefully developed so that it can process signals from each individual antenna, calculate the appropriate beam formed composite signals (one for each satellite/receiver channel) and then process those signals. Multitasking and synchronization mechanisms were developed to support the tracking of multiple channels in real time. To achieve real-time capability, parallel operations are necessary to reduce computation complexity. Bit-wise operations are exploited and implemented in the correlator. Additionally, Single Instruction Multiple Data (SIMD) instructions are used to efficiently calculate the covariance matrix for the beam steering algorithm. The architecture supports at least eighty tracking channels (ten channels from each of seven antennas plus ten composite beam formed signals) in real time. The CRPA software receiver was architected to operate without extensive set up and pre-calibration enhancing its suitability for commercial users. The algorithm design was architected to aid ease of set up. While conventional antenna array system receivers are used with the geometry of antennas and cable lengths known in advance, the algorithm implemented allows for operation without such a priori knowledge. Two beam steering techniques were tested. First is deterministic beam steering. An adaptive algorithm, Minimum Variance Distortion Response (MVDR) algorithm, was implemented to adaptively maximize signal power. The architecture determines of the carrier phase difference between signals from different antennas for a single satellite in order to build the steering vector. An experiment was conducted to show the enhanced C/No and controlled reception patterns through directing the CRPA toward the direction of satellite of interest. For evaluating interference rejection, a LI GPS simulator is used to build an environment with CDMA and CW interferences. The result shows that the MVDR algorithm has reliable performance than non beam steered and deterministic beam steering under the both type of interferences.
A Review of Three Different Studies on Hidden Markov Models for Epigenetic Problems: A Computational Perspective

Recent technical advances, such as chromatin immunoprecipitation combined with DNA microarrays (ChIp-chip) and chromatin immunoprecipitation-sequencing (ChIP-seq), have generated large quantities of high-throughput data. Considering that epigenomic datasets are arranged over chromosomes, their analysis must account for spatial or temporal characteristics. In that sense, simple clustering or classification methodologies are inadequate for the analysis of multi-track ChIP-chip or ChIP-seq data. Approaches that are based on hidden Markov models (HMMs) can integrate dependencies between directly adjacent measurements in the genome. Here, we review three HMM-based studies that have contributed to epigenetic research, from a computational perspective. We also give a brief tutorial on HMM modelling-targeted at bioinformaticians who are new to the field.
Evaluation of formant-based lip motion generation in tele-operated humanoid robots

Generating natural motion in robots is important for improving human-robot interaction. We developed a tele-operation system where the lip motion of a remote humanoid robot is automatically controlled from the operator's voice. In the present work, we introduce an improved version of our proposed speech-driven lip motion generation method, where lip height and width degrees are estimated based on vowel formant information. The method requires the calibration of only one parameter for speaker normalization. Lip height control is evaluated in two types of humanoid robots (Telenoid-R2 and Geminoid-F). Subjective evaluation indicated that the proposed audio-based method can generate lip motion with naturalness superior to vision-based and motion capture-based approaches. Partial lip width control was shown to improve lip motion naturalness in Geminoid-F, which also has an actuator for stretching the lip corners. Issues regarding online real-time processing are also discussed.
ASTE Observations of Nearby Galaxies: A Tight Correlation between CO J = 3–2 Emission and H$\alpha$

Star formation rates (SFRs) obtained via extinction-corrected H˛ are compared to dense gas, as traced by 12 CO ( J= 3–2) emission at the centers of nearby galaxies, observed with the ASTE telescope. It is found that, although many of the observed positions are dusty, and therefore heavily absorbed at H˛ ,t heSFR shows a striking correlation with dense gas in the form of the Schmidt law with an inde xo f 1.0. The correlation is also compared between gas traced by 12 CO ( J= 1–0) and the application of an H˛ extinction correction. We fin dt hat dense gas produces a
EVALUATION OF USER PRACTICES DURING COLLABORATIVE PROCESSES THROUGH PROPOSED HISTORICAL PROJECTION

The paper focuses on the domain of user behaviour evaluation in the collaborative processes performed in a virtual user environment. Proposed historical projection of activities performed in such an environment provides several analytic perspectives materialised in form of different tools, but all of them are based on suitable visualization and extraction techniques. The differences are based on different analytical tasks to be supported by particular analytic tools. We will describe two of these analytic tools, but only one in more details because of our direct involvement in the design and implementation of this tool as project partner in the IST European project called KP-Lab. The main technological output of this project is represented by KP-Lab System as an original platform for support of collaborative working and learning practices based on knowledge creation metaphor. The first analytic approach is based on interactive visualisation of available historical data based on user requirements in simple and user friendly graphical formats as graphs or charts. The second analytic approach provides historical retrospective of performed collaborative processes based on timeline form visualisation of performed events with different selection a patterns’ search capabilities. These two approaches can be used instead of often used manual methods of user behaviour evaluation e.g. in a learning course. Manual evaluation is much more time consuming and tedious for teachers or researchers from several reasons: necessary collection of all materials from students, laborious analysis of their communication channels etc.; e.g. in this case it is difficult to identify the real involvement of each student. Suitable visualisation of automatically collected data with the possibility to define constraints based on users’needs provides easier approach, mainly in the case of large students’ groups. In our paper we will describe our motivation, related works, briefly the first analytical approach and the second one in more details as an important output of our research group.
ADMINISTRATIVE RECORDS EXPERIMENT IN 2000 : OUTCOMES EVALUATION

This paper presents selected results from the Administrative Records Experiment in 2000 (AREX 2000). AREX 2000 used administrative records to enumerate the population in two test sites and compared the results to Census 2000. The test sites included two Maryland and three Colorado counties that offered distinct challenges to the enumeration process. The Outcomes Evaluation assessed two enumeration methods, compared county and sub-county population counts to Census results, and examined the impact of race imputation and other processing issues. The results confirm that administrative records provide good estimates of Census household population counts at larger geographies with greater accuracy using the Bottom-Up enumeration method. Both Top-Down and Bottom-Up methods undercounted Census in most counties, with Bottom-Up population counts ranging from 97-102% of Census results. Age and sex differences indicated problems with source administrative files. Most of the AREX race distributions did not accurately replicate Census results, which was attributed to weaknesses in the race imputation methodology. Imputation rates and type of imputation, housing unit characteristics, and presence of non-relative household members were all associated with AREX-Census differences.
ATSI: Augmented and Tangible Sonic Interaction

This paper presents ATSI, a system for sonic augmentation of physical objects with spatialized sounds and their control by gestural interaction. The implementation combines tracking of the users' hands and head with commodity hardware, and binaural spatialized sound rendering over headphones. The user may attach sounds to common objects and the system maintains the correct spatial auditory perspective inside the augmented scene during the actions of attaching sounds, picking and moving the sounding objects, or exploring the scene. Attention has been given to the binaural rendering of distance cues to support the above actions with perceptual realism in small scale environments and for many objects. Through a user study assessing the localization accuracy that can be achieved with the system, we show that sound rendering performance looks appropriate for applications such as auditory displays for context and object specific information, sonic design for architectural planning and interior design, and music applications.
Benchmarking Vulnerability Detection Tools for Web Services

Vulnerability detection tools are frequently considered the silver-bullet for detecting vulnerabilities in web services. However, research shows that the effectiveness of most of those tools is very low and that using the wrong tool may lead to the deployment of services with undetected vulnerabilities. In this paper we propose a benchmarking approach to assess and compare the effectiveness of vulnerability detection tools in web services environments. This approach was used to define a concrete benchmark for SQL Injection vulnerability detection tools. This benchmark is demonstrated by a real example of benchmarking several widely used tools, including four penetration-testers, three static code analyzers, and one anomaly detector. Results show that the benchmark accurately portrays the effectiveness of vulnerability detection tools and suggest that the proposed approach can be applied in the field.
Iterative Total Variation Image Deblurring with Varying Regularized Parameter

Total variation based model is one of the most effective method for image restoration. In this paper, we consider the total variation (TV) based regularization method and evaluate the regularization parameter for the TV based iterative forward-backward splitting (IFBS) approach. Different parameters with different iterations are obtained. The proposed adaptive iterative forward-backward splitting method does not need to know the initial value of the regularization parameter and does not require any information about the perturbation process. Experimental results demonstrate that the adaptive parameter method is efficient and provide competitive performance.

Design, implementation and performance of a modular power electronic transformer (PET) for railway application

Nowadays, power electronic transformers (PETs) are under consideration in various applications since PETs offer several advantages over traditional low-frequency transformers, including reduced weight and energy saving. This paper describes the practical design and implementation of a modular PET demonstrator, which is to be installed in a test locomotive and to operate in the field. The experimental results, including the performance of the developed PET demonstrator with different operating conditions, are presented.
Hybrid Stars that Masquerade as Neutron Stars

We show that a hybrid (nuclear+quark matter) star can have a mass-radius relationship very similar to that predicted for a star made of purely nucleonic matter. We show this for a generic parameterization of the quark matter equation of state and also for an MIT bag model, each including a phenomenological correction based on gluonic corrections to the equation of state. We obtain hybrid stars as heavy as 2 M☉ for reasonable values of the bag model parameters. For nuclear matter, we use the equation of state calculated by Akmal and coworkers using many-body techniques. Both mixed and homogeneous phases of nuclear and quark matter are considered.
Predicting when Two-Sided Ads will be More Effective than One-Sided Ads: The Role of Correlational and Correspondent Inferences

Two-sided ads often are more credible than one-sided ads because they admit that the advertised brands have shortcomings. Findings about the effectiveness of such ads have been inconclusive, however, perhaps because a critical moderator has been ignored. The author found that a two-sided ad was more effective than one-sided ads only when negatively correlated (vs. uncorrelated) attributes were featured. The brand's unfavorable positioning on the negatively correlated secondary attribute per se (i.e., “correlational inferences”), as well as the advertiser's honesty (i.e., “correspondent inferences”), jointly enhanced judgments of the brand on the primary attribute and thus overall brand evaluations.
SLOW-RELEASE FLUORIDE DEVICES: A LITERATURE REVIEW

Although the prevalence of caries has decreased dramatically over the past decades, it has become a polarised disease, with most of subjects presenting low caries levels and few individuals accounting for most of the caries affected surfaces. Thus it become evident for the need of clinical approaches directed at these high-risk patients, in order to overcome problems related to compliance and low attendance at dental care centres. Slow-release fluoride devices were developed based on the inverse relationship existing between intra-oral fluoride levels and dental caries experience. The two main types of slow-release devices – copolymer membrane type and glass bead – are addressed in the present review. A substantial number of studies have demonstrated that these devices are effective in raising intra-oral F concentrations at levels able to reduce enamel solubility, resulting in a caries-protective effect. Studies in animals and humans demonstrated that the use of these devices was able to also protect the occlusal surfaces, not normally protected by conventional fluoride regimens. However, retention rates have been shown to be the main problem related to these devices and still requires further improvements. Although the results of these studies are very promising, further randomised clinical trials are needed in order to validate the use of these devices in clinical practice. The concept of continuously providing low levels of intra-oral fluoride has great potential for caries prevention in high caries-risk groups.
Post-tetanic decay of evoked and spontaneous transmitter release and a residual-calcium model of synaptic facilitation at crayfish neuromuscular junctions

The post-tetanic decay in miniature excitatory junction potential (MEJP) frequency and in facilitation of excitatory junction potentials (EJPs) was measured at crayfish neuromuscular junctions. A 2-s tetanus at 20 Hz caused the MEJP frequency to increase an average of 40 times and the EJP amplitude to increase an average of 13 times. Both MEJP frequency and EJP facilitation decayed with two time constants. The fast component of MEJP frequency decay was 47 ms, and that of EJP facilitation was 130 ms. The slow component of MEJP frequency decay was 0.57 s, and that of EJP facilitation was approximately 1 s. These results were consistent with the predictions of a residual calcium model, with a nonlinear relationship between presynaptic calcium concentration and transmitter release.
Scientific Visualization in Astronomy: Towards the Petascale Astronomy Era

Abstract Astronomy is entering a new era of discovery, coincident with the establishment of new facilities for observation and simulation that will routinely generate petabytes of data. While an increasing reliance on automated data analysis is anticipated, a critical role will remain for visualization-based knowledge discovery. We have investigated scientific visualization applications in astronomy through an examination of the literature published during the last two decades. We identify the two most active fields for progress — visualization of large-N particle data and spectral data cubes—discuss open areas of research, and introduce a mapping between astronomical sources of data and data representations used in general-purpose visualization tools. We discuss contributions using high-performance computing architectures (e.g. distributed processing and GPUs), collaborative astronomy visualization, the use of workflow systems to store metadata about visualization parameters, and the use of advanced interaction devices. We examine a number of issues that may be limiting the spread of scientific visualization research in astronomy and identify six grand challenges for scientific visualization research in the Petascale Astronomy Era.
Understanding the relationship between mindfulness and eating behaviour

Mindfulness is a meditation practice and personality trait that concerns the extent to which an individual attends to present-moment experience in an open and non-judgemental manner. Mindfulness has been associated with a wealth of benefits for both psychological and physical wellbeing. With respect to eating behaviour, mindfulness has been linked with more favourable eating practices and positive outcomes for weight management, encompassing reduced energy intake, greater intake of fruit and vegetables, lower BMI, and greater success in weight loss efforts. In order to best apply mindfulness to eating and weight management a greater understanding of the mechanisms underlying the relationship between mindfulness and eating would be beneficial. Here, I investigated these mechanisms by focusing on the extent to which mindfulness may allow greater self-regulation of eating behaviour. Across six studies I used a variety of methods to examine processes of self-regulation in relation to mindfulness in the context of eating behaviour. This included investigating the mediating role of executive function in determining food consumption following a mindfulness induction, as well as implementing food cueing paradigms that manipulated the need for self-control to observe effects of dispositional mindfulness on eating behaviour. Finally, I examined the cognitive accessibility of dieting goals and motivational styles of behavioural regulation in relation to mindfulness and how they predicted weight and diet outcomes across time. Overall, the effects of mindfulness on eating behaviour were nuanced and complex. Rather than simply reducing energy intake per se, mindfulness may increase healthy food choices or act as a moderator of effects, and its benefits may be overridden by the motivational state of hunger. I found no evidence for enhanced self-control in the form of executive function or accessibility of dieting goals as being a mechanism underlying the effects of mindfulness. Instead, mindfulness may be predictive of slower responses to food stimuli and specific styles of behavioural regulation which represent more deliberative self-regulation rather than automatic self-control.
Knowledge Contexts-Through the Theoretical Lens of Niklas Luhmann

Context is considered to be an important aspect of knowledge work. However, understanding of knowledge context is dominated by a perspective that assumes that context can be predefined and applicable to all knowledge work. In this paper it is argued that this approach cannot accommodate the dynamic and emergent nature of knowledge work. Using Niklas Luhmann’s socio-theoretical concepts, a definition of knowledge context is developed which extends current understanding and addresses the shortcomings of the conventional approach.
A Model of Computer Live Forensics Based on Physical Memory Analysis

This paper provides a look at some of the shortcomings of current approaches to live forensics. On this basis, a model of computer live forensics based on physical memory analysis is proposed. The model can be used to effectively address many of the challenges facing the conventional live forensics. Then taking the credibility of digital evidence as a starting point, the issue of credibility of live forensic is then put forward for study. Finally, methods of credibility calculation are given through probabilistic and statistical computing. This work may help to improve the scientific credibility of the digital evidence acquired by live forensic in current practice.
Impact of Ad Libraries on Ratings of Android Mobile Apps

One of the most popular ways to monetize a free app is by including advertisements in the app. Several advertising (ad) companies provide these ads to app developers through ad libraries that need to be integrated in the app. However, the demand for ads far exceeds the supply. This obstacle may lead app developers to integrate several ad libraries from different ad companies in their app to ensure they receive an ad with each request. However, no study has explored how many ad libraries are commonly integrated into apps. Additionally, no research to date has examined whether integrating many different ad libraries impacts an app's ratings. This article examines these two issues by empirically examining thousands of Android apps. The authors find that there are apps with as many as 28 ad libraries, but they find no evidence that the number of ad libraries in an app is related to its possible rating in the app store. However, integrating certain ad libraries can negatively impact an app's rating.
