Background Noise Reduction in Wind Tunnels using Adaptive Noise Cancellation and Cepstral Echo Removal Techniques for Microphone Array Applications

Two experiments were conducted to investigate Adaptive Noise Cancelling and Cepstrum echo removal post-processing techniques on acoustic data from a linear microphone array in an anechoic chamber. A point source speaker driven with white noise was used as the primary signal. The first experiment included a background speaker to provide interference noise at three different Signal-to-Noise Ratios to simulate noise propagating down a wind tunnel circuit. The second experiment contained only the primary source and the wedges were removed from the floor to simulate reflections found in a wind tunnel environment. The techniques were applicable to both signal microphone and array analysis. The Adaptive Noise Cancellation proved successful in its task of removing the background noise from the microphone signals at SNRs as low as -20 dB. The recovered signals were then used for array processing. A simulation reflection case was analyzed with the Cepstral technique. Accurate removal of the reflection effects was achieved in recovering both magnitude and phase of the direct signal. Experimental data resulted in Cepstral features that caused errors in phase accuracy. A simple phase correction procedure was proposed for this data, but in general it appears that the Cepstral technique is and would be not well suited for all experimental data.

Motion Recognition Assisted Indoor Wireless Navigation on a Mobile Phone

The paper presents an indoor navigation solution combining physical motion recognition with WLAN positioning on a smart phone. Orientationindependent features are extracted from vertical and horizontal components of acceleration. The simple features such as the mean of horizontal acceleration, the variance of acceleration magnitude, and the variance of horizontal acceleration are selected as the nodes in a decision tree. Six common motion modes during indoor navigation, e.g., static, standing with hand swinging, normal walking with holding the phone in hand, normal walking with hand swinging, fast walking, and U-turning are detected. A fingerprinting based WLAN positioning approach offers the headings and initial positions for pedestrian dead reckoning with about 10 seconds interval. The velocities for six motion modes are trained by five testers and applied in the dead reckoning during the WLAN positioning gap. Test results indicate that the motion mode is recognized correctly in 95% of test cases. The field test shows 4.6m horizontal mean error for motion recognition assisted indoor wireless positioning.
Adaptive Resource Allocation for Wireless Body Sensor Networks

Wireless Body Sensor Network (WBSN) technologies are one of the main research elds in the health care and entertainment industry. These technologies aim to one day become mature enough to improve the quality of human life. For example, WBSN technologies are able to control and monitor the health status of a patient at all times, alert patients or practitioners about abnormal physical health status that otherwise would have been ignored or remained unnoticed by the patient, give enough time to the patient to seek medical care, and thus help to cure illness before symptoms become visible or the physical health of the patient becomes critical. They allow elderly and chronically ill people to maintain their independence without need for constant supervision or the presence of caregivers. WBSNs are an attractive proposal for such scenarios due to the ease of installation, their small size, low cost, low power consumption and low maintenance. Although WBSNs have signi cant bene ts, their characteristics create numerous challenges, namely: network mobility in urban environments, interference caused by other technologies sharing the same frequency band, and most importantly, limited resources such as nite power supply, computational power, storage capacity and communication capabilities. This thesis investigates adaptive resource allocation embedded into IEEE 802.15. 4based WBSNs with the aim to address the interference problem while reducing the overall energy consumed. In particular, the primary goal of this thesis is to maintain a reliable data communication between sensor nodes and their corresponding coordinator node by physical-layer resource allocation (frequency, and transmit power). Furthermore, our secondary goal is to increase the overall lifetime of the network by optimising energy consumption of the WBSN nodes. All these require the pro-
Basics of Bioinformatics in Biological Research

The concept of laboratory rat is giving way to the computer mouse arose after the famous handshake between Clinton-Blair for the completion of the human genome in April 2003. Bioinformatics is defined as the application of computational techniques to understand and organize the information associated with biological macromolecules. There is availability of large databases of genomic information which has enabled research efforts for discovering methods for diagnosis and treatment of human diseases using DNA microarrays and proteomics experiments. But there are various problems while doing this like it’s always challenging to develop proper and sophisticated analysis method which can properly use genomic data bases considering its and heterogeneity of the data. The main purpose of this first paper is to explore and explain Bioinformatics in a more scientific way, and try highlighting applications of bioinformatics in the medical sector.

Evolution and usability of mobile phone interaction styles

Author Harri Kiljander Title Evolution and Usability of Mobile Phone Interaction Styles Over one billion people own or use cellular mobile telephones. Therefore, industry practitioners are faced with a question: how big steps can they take when designing the user interfaces for their new products, or how closely should they stick with the already existing user interface conventions that may already be familiar to the consumers. The objective of this research work is to create and communicate new knowledge for design and usability practitioners about how to design and evolve interaction style conventions in mainstream, voice-centric mobile telephones. In the context of this study, interaction style denotes the framework consisting of the physical interaction objects, the abstract interaction elements, and the associated behavior or interaction conventions that are applied throughout the core functionality of the mobile phone, but excludes the stylistic appearance elements of the user interface. The main research problem — how do mobile phone interaction style changes affect the initial usability of a mobile phone for users with earlier experience with mobile phones — is approached via several methods. A literature study compares the interaction styles applied in mainstream computing domains against the aspects relevant in the mobile phones domain. A heuristic analysis of contemporary mobile phones is used to formulate an understanding of the available interaction styles and analyze whether there is convergence towards specific types of interaction styles in the industry. An empirical usability testing experiment with 38 test users is conducted with a novel mobile phone interaction style to investigate differences between users who are already familiar with different mobile phone interaction styles. The study reveals that interaction styles applied in contemporary mobile telephones are designed around menu navigation, and they implement the three primary operations — Select, Back and Menu access — with dedicated hardkeys, context-sensitive softkeys, or using special control devices like joysticks or jog dials. The control keys in the contemporary interaction styles are converging around various twoand three-softkey conventions. The aspects related to indirect manipulation and small displays pose specific usability and UI design challenges on mobile phone user interfaces. The study shows that the mobile handset manufacturers are applying their usually proprietary interaction styles in a rather consistent manner in their products, with the notable exception of mobile Internet browsers that often break the underlying interaction style consistency. Based on the results from the empirical usability testing, we claim that despite differences between interaction styles in contemporary mobile phones, users do not face significant difficulties when transferring to a novel mobile phone model.

Will the Machine Like Your Image?Automatic Assessment of Beauty in Images with Machine Learning Techniques †

Although the concept of image quality has been a subject of study for the image processing community for more than forty years (where, with the term “quality”, we are referring to the accuracy with which an image processing system captures, processes, stores, compresses, transmits, and displays the signals that compose an image), notions related to aesthetics of photographs and images have only appeared for about ten years within the community. Studies devoted to aesthetics of images are multiplying today, taking advantage of the latest machine learning techniques and mostly due to the proliferation of huge communities and websites, specialized in digital photography sharing and archiving, such as Flickr, Imgur, DeviantArt, and Instagram. In this review, we examine the latest advances of computer methods that aim at computationally distinguishing high-quality from low-quality photos and images, relying on machine learning techniques. The paper is organized as follows: First, we introduce many approaches to aesthetics, studied in philosophy, neurobiology, experimental psychology, and sociology, to see what lighting they propose to researchers. Such points of view let us explain the weakness of the current consensus on the difficult aesthetics problem and the importance of the ongoing debates on it. Then, we analyze the work done in the community of pattern recognition and artificial intelligence on the task of automatic aesthetic assessment, and we both compare and critically examine the presented results. Finally, we describe many issues that have not been addressed, and starting from these, we outline some possible future directions.

The Practice and Evaluation of Applying PBL to e-Learning via Screencasting: Implications for Computing Courses

As the practice of e-learning continues to proliferate, online educators, especially in the computing disciplines, are facing special challenges. This chapter represents an effort in moving the existing problem-based learning (PBL) paradigm to e-learning through the use of screencasts. In the form of an empirical case study, the chapter provides empirical evidence and indicative support for the successful application and evaluation of PBL methods in a highly technical computing course that has traditionally been taught in a face-to-face setting. This chapter makes a unique contribution to the e-learning research with respect to the applicability of PBL methods in the online environment and the exciting possibilities for screencasting as an instructional technology. It also offers implications for creating elearning courses that can prepare students to develop lifelong problem solving skills and become more motivated and responsible learners in today’s networked society.

Nevertheless, the frequent presence of non-normative linguistic phenomena that can make any automatic processing challenging. In this paper is described the partici- pation in the Text Normalisation Workshop at the SEPLN conference (Tweet-norm 2013). The Workshop includes one unique task focused on the normalisation of Spa- nish tweets. For this task we have used TENOR, a multilingual lexical normalisation tool for Web 2.0 texts.
Time Domain Analysis Using a Network Analyzer

Time domain analysis is useful for measuring impedance values along a transmission line and for identifying a device problem in time or distance such as discontinuity.The time domain testing result provides a more intuitive and direct look about the characteristics of the device-under-test(DUT). Compared with other measuring techniques,it gives more meaningful information concerning the broadband response of a transmission system by showing the effect of each discontinuity as a function of time or distance.This paper will focus on the time domain analysis using the vector network analyzers(VNAs). The intent is to provide engineers with frequency domain background and an in-depth view of how a time domain display is created from the frequency domain data(S-parameters)and how to apply the time domain display to common problems in RF systems.
Fingerprint Image Quality: Predicting Biometric Performance

Finger image quality assessment is a crucial part of any system where a high biometric performance and user satisfaction is desired. Several algorithms measuring selected aspects of finger image quality have been proposed in the literature, yet only few of them have found their way into quality assessment algorithms used in practice. We provide comprehensive algorithm descriptions and make available implementations of adaptations of 10 quality assessment algorithms from the literature which operate at the local or global image level. We evaluate the performance on four datasets in terms of the capability in determining samples causing false non-matches and by their Spearman correlation with sample utility. Our evaluation shows that both the capability in rejecting samples causing false non-matches and the correlation between features varies depending on the dataset. 4.
Film notes: masculinity, violence, and queer identity in recent South African films

Told from multiple points of view, Vaya (meaning “to go”) follows the stories of three unrelated characters whose fates intertwine as they leave their hometowns in rural KwaZulu-Natal and head for Johannesburg – South Africa’s economic hub – on their respective personal quests. The script, which took several years to write, was developed out of the true stories of members of the Homeless Writers Project. This project runs story workshops with people in Johannesburg who are, or have been, homeless. While the intertwining of the storylines is a fictional device that gives structure to the plot, the individual stories thus reflect the real experiences of the writers. A young woman, Zanele (Zimkhitha Nyoka), is accompanying a girl child to the city to reunite the child with her mother, who manages a tavern. Nkulu (Sibusiso Msimang) must retrieve the body of his dead father, a mineworker, and return it to his grieving mother for burial in order to preserve the dignity of the family in the face of village gossip. Nhlanhla (Sihle Xaba) hopes to make quick money in order to pay lobola for the woman he wants to marry by doing unspecified work for his cousin Xolani (Warren Masemola). As their stories unfold, each character finds himself or herself in a precarious position: Zanele and her charge narrowly escape a human trafficking ring but are stranded in the city with no money and no contacts. Nkulu discovers that his father’s second, wealthy family have already claimed his body and refuse to give it up, and Nhlanhla is submitted to a harrowing gang initiation that culminates in homicide. The film’s ending is ambiguous, and the fates of the characters haunt the viewer long after the final aerial shot of homeless people washing in a polluted Johannesburg river has faded to black. Although the film is marketed as a drama, its aesthetics are those of a noir thriller. The stunning cinematography by Kabelo Thathe renders Johannesburg by turns vast

Return of the Tariffs: The Interwar Trade Collapse Revisited

Was the collapse of world trade between 1928 and 1937 caused by higher transport costs, increased protectionism or the collapse of the gold standard? Using recent advances in the estimation of gravity equations, I examine the partial and general equilibrium effects of bilateral distance, international borders, and the payment system on trade. My results suggest that had average tari and non-tari trade barriers remained at their 1928 level, total international trade would have been 64.6 % higher in 1937. Had the gold standard not collapsed in 1931 and had the British Empire not departed to establish its own currency and trade blocs, international trade would have been 3 % larger. Finally, had transport costs remained at their 1928 level, global trade would not have been significantly different nine years on. These results are supported by over 6,000 new hand-collected observations of ad-valorem ocean freight rates for cotton, which show an average increase of only 1.2 percentage points between 1928 and 1936. When expressed as an index, the movement of freight rates mirrors the evolution of the elasticity of trade to distance over the period.

Previsiones económicas para España 2019-2021

La economia espanola crecio a una tasa interanual del 2,4% en el primer trimestre de 2019, superando ligeramente las previsiones existentes a comienzos de ano. Dicha aceleracion procedio en su totalidad de la inversion en bienes de equipo, mientras que el consumo privado modero levemente su ritmo de crecimiento. Bajo el supuesto de una leve recuperacion de la economia mundial, las proyecciones situan en un 2,2% el crecimiento durante el conjunto del ano 2019, con una suave desaceleracion en 2020 y 2021, hasta un 1,8% en ambos casos. En estas condiciones, se crearian cerca de 930.000 empleos en el proximo trienio, lo que permitiria una reduccion de la tasa de paro hasta el 11,4% en 2021. Los mayores riesgos provienen del exterior, destacando entre ellos las tensiones comerciales entre los Estados Unidos y China, y la probable entrada de la industria europea en una fase de reestructuracion mas profunda de lo anticipado.
