A Speech Enhancement Method Based on AR Model

Some traditional speech enhancement methods are analyzed and compared,which include spectral subtraction and Minimum Mean Square Error method.Then,based on the autoregressive and moving average theory,the color noise is modeled and a new speech enhancement algorithm based on AR model is obtained.In the end,simulation experiments are conducted under three kinds of color noise conditions and within-5～5 dB signal-to-noise ratio range.The experiments demonstrate the good performance of the proposed method,which can whiten the noisy speech and keep the original speech perfect.
Proceedings of the 3rd International Workshop on Search-Driven Development: Users, Infrastructure, Tools, and Evaluation

The third international workshop on Search-Driven Development: Users, Infrastructure, Tools and Evaluation (SUITE 2011) focuses on exploring the notion of search as a fundamental activity during software development. As software development is a process of both information creation and information gathering, software developers are constantly engaged in activities that search for the pertinent information to solve their problems at hand. The information needs of software developers range from those related to code (writing, changing, fixing, communicating code) to process (design) and people (colleagues). SUITE is a workshop series that seek to understand and find solutions to address such a wide range of software developers' information needs. The goal of the workshop is to identify the search driven nature of software development as a key research topic. Topics related to search driven development range from core technical issues to human aspects. Therefore, SUITE 2011 aims to bring together researchers and practitioners with diverse interests and backgrounds in Software Engineering, Human Computer Interaction, Information Retrieval etc. SUITE 2011 aims to attract and foster a community of researchers who are interested in understanding and fulfilling various information needs during software development. SUITE 2011 will be a venue to discuss the problems and state-of-the-art; share ideas and results; and, set future directions in the area of Search-Driven development.
A Gossiping Framework for Scalaris

Gossiping is a technique for solving communication and computation tasks in peer-to-peer systems. It refers to the periodic, pairwise, message exchange between random peers in a network. Gossiping provides probabilistic guarantees on convergence speed and accuracy and features very good scalability, robustness and uniform load distribution. The two most important classes of gossiping algorithms are gossip based information dissemination and gossip based aggregation. Scalaris is a distributed key-value store with guarantees of atomicity, concurrency, isolation and durability on transactions (ACID properties). It is completely based on peer-to-peer techniques and uses gossiping for several purposes. The contribution of this work is is twofold: First, to conceptualise and implement a gossiping framework for Scalaris. An appropriate abstraction of different gossiping algorithms is established and used for the implementation. Second, the gossip based aggregation of load information in Scalaris is to be improved. The symmetric push-sum protocol is selected as aggregation algorithm and extended to allow histogram computation and periodic restarting. It is then implemented on the basis of the framework.
Format for human body modelling from 3‐D body scanning

Presents a standard data format for describing and interpolating 3‐D human body shapes from data collected by a 3‐D body scanner. The body data were treated as a series of horizontal cross‐sections. Each cross‐section was described by 16 data points. The 3‐D surface can be calculated by interpolating between these sections. This procedure allowed editing and manipulation of raw scanned data, as well as substantial data reduction. Horizontal cross‐sections of the body were chosen to correspond to particular anatomical surface landmarks, rather than distances from a reference point. Hence, each data element described a particular anatomical location, irrespective of body shape and size. This feature allowed comparison and averaging of 3‐D shapes, greatly enhancing the application of 3‐D scanned data. The standard data format allows 3‐D scanned data to be transferred into CAD/CAM systems for automated garment design and manikin manufacture.
Neural network based intrusion detection system for detecting changes in hardware profile

Abstract To protect the information and/or the system maintaining the information is a challenge in fast growing electronic information age. Some of the technological components available in a multilayered IT security policy are Authorization, access controls, and confidentiality. The intrusion detection systems are one of the most widely accepted solutions as cryptographic protocols rely on prevention as the sole means of defense. This paper discusses neural network based intrusion detection system for detecting changes in the hardware profile. For carrying out this work, back propagation network (BPN) architecture is used. Analysis is carried out on performance log for finding out if an unauthorized access to the system has been made to change its hardware profile. Analysis of these logs shows positive results of implementing Neural Network approach for different kind of intrusions.
A Virtual Chinese Keyboard BCI System Based on P300 Potentials

The Human-Computer Interaction(HCI) technology realm has witnessed the rise of new HCI channels in recent years,which is powered by enhancement of various signal-processing methods following the computer capacity boost in the last decade.Brain-Computer Interface(BCI),which has attracted broad notice,is one of such channels.The P300-based BCI utilizes the endogenous P300 event related potentials to decode user's intention.Most of previous applications of P300-BCI systems were targeted at English letter input.Our research developed the first Chinese input online BCI system based on P300 potentials.We took advantage of the stroke-comprising characteristics of Chinese characters to simplify the P300 induction interface,and designed the Chinese typing virtual keyboard accordingly.Online human experiments showed that the Chinese BCI idea is viable,and further improvement of the system could provide the Chinese-speaking paralyzed patients a new option to restore their body functions.

Concepts to capture Relations between Project Documents using Ontologies

It is difficult to reveal erroneous assumptions in software projects due to mostly only implicit relations between project documents. Errors that result from these assumptions are expensive to fix in later project phases. Capturing relations between project documents helps to verify documents and detects potential erroneous assumptions early in a project, hence can avoid errors early that might be expensive to fix later. This thesis contributes an approach that uses the mechanisms of ontologies to verify project documents against requirements expressed in a controlled language. Natural language, a major component in mostly early phase documentation of software projects, is a source of ambiguity in requirements and project documents and can lead to misunderstandings. This thesis proposes a controlled natural language (CNL), based on a grammar definition, with a restricted vocabulary and sentence structure to formulate requirements with reduced ambiguity. In order to relate project documents, a generic format is required to compare the documents’ contents. This thesis describes an approach to transform the knowledge in project documents into an ontology. The ontology is built using semantically annotated productions in a CNL for requirements. Different types of semantic annotations are proposed and the semantic conflicts that can arise between them are discussed. Furthermore, a semantic meta-grammar is presented that allows the definition of grammars whose languages contain semantically annotated sentences. The concepts presented in this thesis are prototypically implemented in a tool which enables the user to write unambiguous requirements that are translated into ontology axioms. These axioms are used to capture relations between project documents that the user can import into the tool.
The integration of CL resources in CALL for Irish in the primary school context

It is difficult to integrate Computational Linguistics (CL) techniques in Computer-Assisted Language Learning (CALL) artefacts. The Computational Linguistics Integrated in CALL for Irish (CLICI) research1 presented in this dissertation aims to re-use existing CL resources and where suitable ones do not exist, to build its own modular, re-usable resources. The research question addressed was: can existing CL resources be integrated successfully in useful CALL artefacts for Irish for English-medium primary schools in Ireland? Irish is a compulsory subject in Irish primary schools but there are complex socio-cultural issues surrounding the teaching and learning of the language and in general CALL resources are not available for this group of learners. CL techniques and resources generally do not have CALL as a primary focus. There are often technical and pedagogical problems when CL and CALL researchers aim to integrate them in CALL artefacts. The CLICI project aimed to learn from previous CLICALL projects and determine the pedagogical needs in the deployment context first, and then to consider how CL techniques and resources can be used in CALL artefacts to address these needs. The project followed a structured approach to CALL design and development, using the Analysis Design Development Implementation Evaluation (ADDIE) courseware lifecycle. The CLICI project consists of three components: a Lesson Generation Component (LGC), a Verb Conjugation Component (VCC) and a Writing Checker Component (WCC). The LGC is a tool that facilitates the development of CALL lessons. The VCC enables automatic creation of animated verb conjugation lessons. The WCC enables students to enter free-form texts in Irish and provides feedback. The CLICI project demonstrated that it was possible to integrate existing CL resources in useful CALL artefacts for Irish in English-medium primary schools. However, the main determiner of success lies in the hands of the teachers and students.
Supporting young children drawing: developing a role

This article recognizes drawing as a child-appropriate symbolic activity young children use to make meaning in the world. Evidence from a three-year longitudinal study (Ring, 2003; Anning & Ring, 2004) of seven young children drawing at home, pre-school and school is taken as a starting point for considering the role of adults in supporting young children's drawing behaviours. Narrative is also drawn from an ongoing research project in which experienced teachers in English educational settings working with children aged between 3 and 5 years chart their exploration of their role as they strive to 'tune in' to their needs in relation to drawing. The article highlights the importance of adults making time and space for drawing; ensuring the materials they provide engage both genders; recognizing a wider range of drawing activity as 'developmentally appropriate' for meaning-making; developing and valuing their role as 'co-constructors' working alongside children. The emergent findings show the importance of supporting drawing on both a large and small scale, outdoors as well as indoors for both girls and boys.
Agglomerative clustering for community detection in dynamic graphs

To my grandfather, for showing me that the real-world is much more amazing than fantasy. ACKNOWLEDGEMENTS Switching my major from Aerospace Engineering to CSE for my Masters at Georgia Tech, made moving to a new country feel like a rather blanched change in comparison. While the last two years have been anything but cozy, I believe my marginal learning over this short span exceeds everything heretofore. It has truly given me an opportunity to remold myself into someone I aspired to be, at the onset. That indeed is the true purpose of education I believe. A major part of this learning has come from this Masters Thesis, for which I am indebted to my advisor, Prof. David Bader for giving me the opportunity, guidance and assistance throughout my study and research. I would also like to express my deepest gratitude to Dr. Jason Riedy without who's encouragement, expert advice and generous support, I couldn't even have imagined working on a topic as formidable as Graph Theory, given my distinct background. I always secretly believed Graph Theory was a cool topic. I can now confirm that my belief was well-founded. Thank you to Prof. Bistra Dilkina for being a part of my Thesis Committee and for the valuable insights. And thanks to James and Anita for all their spontaneous assistance in my research. Many thanks are also in order for my friends, for adding color to my time here at Georgia Tech. And finally, the acknowledgements would not be complete without thanking Reddit, Quora and the countless such time sinks, without which I would've probably been more productive, but life would've been much more drab, had I not known " The longterm effects of immortality on humans " .
The Good Collusion Defeats the Lone Ranger

We all collaborate from birth, in learning language for instance, in learning to play, and as writers. This paper discusses collaborative practice, how creative writers work with each other, including composite authorship as collaboration, as well as collaborative projects with visual and/or sound artists to generate material outside of conventional forms. Various questions are explored; what issues emerge in creative collaboration, especially cross-arts? How might one’s voice, or aesthetics, affect creative text? How might this kind of creativity be a social process? I will utilize examples from established collaborative partnerships. The paper addresses the concept and practicalities of collaboration, the issues and processes,and gives a brief discussion of theoretical ideas around these issues
On the Nature of Things = de Rerum Natura

Titus Lucretius Carus was probably born in the early first century B.C., and died in the year 55. Little is known of his life, although two tantalizing bits of gossip were passed on by St. Jerome: that he was poisoned by a madness-inducing aphrodisiac given him by his wife, and that his great poem On the Nature of Things was posthumously edited by Cicero. For the latter assertion, writes Anthony Esolen in his introduction to the present volume, there is little evidence, and none whatsoever for the former. What does survive is a masterful poetic work that stands as the greatest exposition of Epicurean philosophy. Writing in the waning days of the Roman Republic-as Rome's politics grew individualistic and treacherous, its high-life wanton, its piety introspective and morbid-Lucretius sets forth a rational and materialistic view of the world which offers a retreat into a quiet community of wisdom and friendship. Even to modern readers, the sweep of Lucretius's observations is remarkable. A careful observer of nature, he writes with an innocent curiosity into how things are put together-from the oceans, lands, and stars to a mound of poppy seeds, from the "applause" of a rooster's wings to the human mind and soul. Yet Lucretius is no romantic. Nature is what it is-fascinating,purposeless, beautiful, deadly. Once we understand this, we free ourselves of superstitious fears, becoming as human and as godlike as we can be. The poem, then, is about the universe and how human beings ought to live in it. Epicurean physics and morality converge. Until now, there has been no adequate English verse translation of Lucretius's work. Anthony Esolen fills that gap with a version that reproduces-with remarkable faithfulness-the meaning, pace, and tone of the original Latin. Here is a book that will introduce a new generation of readers to a thinker whose powers of observation and depth of insight remain fresh to the present day. "Esolen has the rare gift of being both a fine poet and a lover of languages. His diction is poetic and natural; he has a fine ear for sound, and the translation benefits greatly from being read aloud-as Latin poetry was meant to be. This translation is clear and forceful. It can, and will, be read. "-Kenneth J. Reckford, University of North Carolina, Chapel Hill
Developing an Aboriginal Healing Model for Intergenerational Trauma

Abstract Over the past decade, intergenerational trauma as an explanation for the array of social conditions that exist within Aboriginal communities has been put forward by a number of researchers. This study explored the family histories of 21 Aboriginal men at a homeless shelter, seeking links between personal homelessness and intergenerational trauma. The indicators of intergenerational trauma within four domains are synthesized in the Intergenerational Trauma Model. Recognizing that the healing of intergenerational trauma at the individual level must include family, community and nation, traditional Aboriginal healing practices including healing circles, sweat- lodge, fasting, vision quest and other ceremonies can augment mainstream interventions and motivate the individual to further explore their deep rooted pain. Healing within the intergenerational trauma framework is a slow complicated process and is a difficult journey both for the therapist and the client.
Health, Polysubstance Use, and Criminal Justice Involvement Among Adults With Varying Levels of Opioid Use

Importance Health profiles and patterns of involvement in the criminal justice system among people with various levels of opioid use are poorly defined. Data are needed to inform a public health approach to the opioid epidemic. Objective To examine the association between various levels of opioid use in the past year and physical and mental health, co-occurring substance use, and involvement in the criminal justice system. Design, Setting, and Participants This retrospective, cross-sectional analysis used the 2015-2016 National Survey on Drug Use and Health to assess the independent association of intensity of opioid use with health, co-occurring substance use, and involvement in the criminal justice system among US adults aged 18 to 64 years using multivariable logistic regression. Exposures No opioid use vs prescription opioid use, misuse, or use disorder or heroin use. Main Outcomes and Measures Self-reported physical and mental health, disability, co-occurring substance use, and past year and lifetime involvement in the criminal justice system. Results The sample consisted of 78 976 respondents (42 495 women and 36 481 men), representative of 196 280 447 US adults. In the weighted sample, 124 026 842 adults reported no opioid use in the past year (63.2%; 95% CI, 62.6%-63.7%), 61 462 897 reported prescription opioid use in the past year (31.3%; 95% CI, 30.8%-31.8%), 8 439 889 reported prescription opioid misuse in the past year (4.3%; 95% CI, 4.1%-4.5%), 1 475 433 reported prescription opioid use disorder in the past year (0.8%; 95% CI, 0.7%-0.8%), and 875 386 reported heroin use in the past year (0.4%; 95% CI, 0.4%-0.5%). Individuals who reported any level of opioid use were significantly more likely than individuals who reported no opioid use to be white, have a low income, and report a chronic condition, disability, severe mental illness, or co-occurring drug use. History of involvement in the criminal justice system increased as intensity of opioid use increased (no use, 15.9% [19 562 158 of 123 319 911]; 95% CI, 15.4%-16.4%; prescription opioid use, 22.4% [13 712 162 of 61 204 541]; 95% CI, 21.7%-23.1%; prescription opioid misuse, 33.2% [2 793 391 of 8 410 638]; 95% CI, 30.9%-35.6%; prescription opioid use disorder, 51.7% [762 189 of 1 473 552]; 95% CI, 45.4%-58.0%; and heroin use, 76.8% [668 453 of 870 250]; 95% CI, 70.6%-82.1%). In adjusted models, any level of opioid use was associated with involvement in the criminal justice system in the past year compared with no opioid use. Conclusions and Relevance Individuals who use opioids have complicated health profiles and high levels of involvement in the criminal justice system. Combating the opioid epidemic will require public health interventions that involve criminal justice systems, as well as policies that reduce involvement in the criminal justice system among individuals with substance use disorders.
Introdução à visualização de informações

Information visualization corresponds to the application of interactive computer graphics techniques aiming at supporting data analysis processes by means of graphical representations that can be manipulated by the user. An information visualization technique is based on a visual representation (a picture or image) and interaction mechanisms that allow a user to manipulate it to better understand the data represented in there. The abstraction level in information visualization is high due to the fact that data do not often have a natural physical or geometric representation, or the user is not interested in raw data but needs to search for features or trends inside the data set. This paper is a short survey of this area, presenting some fundamental aspects as well as techniques that illustrate them. This paper also offers a brief discussion on interdisciplinary characteristics of information visualization.
Map Matching for Vehicle Guidance

A two-phase, non-overlapping clock signal is generated in response to a single-phase input clock signal by delaying the input clock signal to produce the first phase output clock signal ( phi 1), producing a delayed signal from the first phase clock signal, and gating the further delayed first phase clock signal with the input clock signal to produce an inverted signal for a second phase clock signal ( phi 2), in order to produce gaps between the trailing edge of one phase of the output clock and the leading edge of the other phase of the output clock signal in order to accommodate dynamic transient conditions that must occur in a following utilization circuit between successive phase clock pulse signals.
