Noise Removal in Speech Processing Using Spectral Subtraction  [PDF]
Marc Karam, Hasan F. Khazaal, Heshmat Aglan, Cliston Cole
Journal of Signal and Information Processing (JSIP) , 2014, DOI: 10.4236/jsip.2014.52006
Abstract:

Spectral subtraction is used in this research as a method to remove noise from noisy speech signals in the frequency domain. This method consists of computing the spectrum of the noisy speech using the Fast Fourier Transform (FFT) and subtracting the average magnitude of the noise spectrum from the noisy speech spectrum. We applied spectral subtraction to the speech signal “Real graph”. A digital audio recorder system embedded in a personal computer was used to sample the speech signal “Real graph” to which we digitally added vacuum cleaner noise. The noise removal algorithm was implemented using Matlab software by storing the noisy speech data into Hanning time-widowed half-overlapped data buffers, computing the corresponding spectrums using the FFT, removing the noise from the noisy speech, and reconstructing the speech back into the time domain using the inverse Fast Fourier Transform (IFFT). The performance of the algorithm was evaluated by calculating the Speech to Noise Ratio (SNR). Frame averaging was introduced as an optional technique that could improve the SNR. Seventeen different configurations with various lengths of the Hanning time windows, various degrees of data buffers overlapping, and various numbers of frames to be averaged were investigated in view of improving the SNR. Results showed that using one-fourth overlapped data buffers with 128 points Hanning windows and no frames averaging leads to the best performance in removing noise from the noisy speech.

Children grow and horses race: is the adiposity rebound a critical period for later obesity?
TJ Cole
BMC Pediatrics , 2004, DOI: 10.1186/1471-2431-4-6
Abstract: Longitudinal changes in body mass index during adiposity rebound, measured both in original (kg/m2) and standard deviation (SD) score units, are studied in five hypothetical subjects. Two aspects of the body mass index curve, the body mass index centile and the rate of body mass index centile crossing, determine a child's age at rebound. A high centile and upward centile crossing are both associated separately with an early rebound, while a low centile and/or downward centile crossing correspond to a late rebound. Early adiposity rebound is a risk factor for later fatness because it identifies children whose body mass index centile is high and/or crossing upwards. Such children are likely to have a raised body mass index later in childhood and adulthood. This is an example of Peto's "horse racing effect". The association of centile crossing with later obesity is statistical not physiological, and it applies at all ages not just at rebound, so adiposity rebound cannot be considered a critical period for future obesity. Body mass index centile crossing is a more direct indicator of the underlying drive to fatness.An early age at adiposity rebound predicts later fatness because it identifies children whose body mass index centile is high and/or crossing upwards. Such children are likely to have a raised body mass index later. Body mass index centile crossing is more direct than the timing of adiposity rebound for predicting later fatness.There is continuing interest and concern about the worldwide epidemic of child obesity, particularly its role in the development of later obesity and adult chronic disease. [1,2] The adiposity rebound is the second rise in adiposity, as measured by body mass index (BMI = weight/height2), which occurs between 3 and 7 years of age in individual children. [3] It corresponds to fat cells starting to increase in number after an earlier phase of increasing then decreasing in size. [4] In an important paper Rolland-Cachera [3] noted that the
From “Animal Machines” to “Happy Meat”? Foucault’s Ideas of Disciplinary and Pastoral Power Applied to ‘Animal-Centred’ Welfare Discourse
Matthew Cole
Animals , 2011, DOI: 10.3390/ani1010083
Abstract: Michel Foucault’s work traces shifting techniques in the governance of humans, from the production of ‘docile bodies’ subjected to the knowledge formations of the human sciences (disciplinary power), to the facilitation of self-governing agents directed towards specified forms of self-knowledge by quasi-therapeutic authorities (pastoral power). While mindful of the important differences between the governance of human subjects and the oppression of nonhuman animals, exemplified in nonhuman animals’ legal status as property, this paper explores parallel shifts from disciplinary to pastoral regimes of human-‘farmed’ animal relations. Recent innovations in ‘animal-centred’ welfare science represent a trend away from the ‘disciplinary’ techniques of confinement and torture associated with ‘factory farms’ and towards quasi-therapeutic ways of claiming to know ‘farmed’ animals, in which the animals themselves are co-opted into the processes by which knowledge about them is generated. The new pastoral turn in ‘animal-centred’ welfare finds popular expression in ‘happy meat’ discourses that invite ‘consumers’ to adopt a position of vicarious carer for the ‘farmed’ animals who they eat. The paper concludes that while ‘animal-centred’ welfare reform and ‘happy meat’ discourses promise a possibility of a somewhat less degraded life for some ‘farmed’ animals, they do so by perpetuating exploitation and oppression and entrenching speciesist privilege by making it less vulnerable to critical scrutiny.
Reinventando las prácticas educativas del pasado para lograr el éxito pedagógico del futuro
Cole,Michael;
Revista de Estudios Sociales , 2011,
Abstract: in this paper i argue that the future of psychological research on educational processes would benefit from an interdisciplinary approach that enables psychologists to locate their objects of study within the cultural, social, and historical contexts of their research. an examination of anthropological accounts of the characteristics of education in small, face-to-face, pre-industrial societies raises the question of why major challenges have confronted contemporary psycho-educational research that seeks to implement major, qualitative changes in modern educational practices by transforming them to have the properties of education in those same face-to-face societies. the paper concludes with a description of a multi-institutional, multi-disciplinary system of education that responds to these challenges while offering a model for educating psychology students in a multi-generational system of activities with potential widespread benefits.

Culture and Cognitive Science
Michael Cole
Outlines : Critical Practice Studies , 2003,
Abstract: The purpose of this paper is to review the way in which cultural contributions to human nature have been treated within the field of cognitive science. I was initially motivated to write about this topic when invited to give a talk to a Cognitive Science department at a sister university in California a few years ago. My goal, on that occasion, was to convince my audience, none of whom were predisposed to considering culture an integral part of cognitive science, that they would indeed benefit from recognizing some affinities between the ideas of some of the founders of cognitive science and ideas about culture emanating from the Soviet (now Russian) cultural-historical school. My task in presenting this argument to the readers of Outlines is most likely the mirror image of that earlier effort. On the one hand, the ideas of the cultural-historical school are well known to this readership and you do not need to be lectured on the topic by an American whose knowledge of the topic is no greater than your own. At best, the ways in which I have appropriated those ideas and put them to work might provide an opportunity to reflect on the strange fate of ideas when they move between national traditions of thought. On the other hand, owing to a double twist of fate (after all, what was an American doing in Moscow in 1962 doing post-doctoral work in psychology) I was also present during the discussions leading to the founding of Cognitive Science in the early 1970’s and subsequently became a member of the Cognitive Science Program at UCSD in the early 1980’s, arguably one of the pioneering efforts to institutionalize this new discipline. My hope is this unusual confluence of experiences, and the ideas that they have generated, will be of some use to those who see value in a dialogue between these different intellectual projects. With this goal in mind, I will begin by providing my own brief history of key ideas associated with the origins of cognitive science. My presentation will of necessity be highly selective – it is the relevance of the inclusion of culture in cognitive science that is my major focus. I will then summarize some major milestones in the development of cognitive science at UCSD before turning to describe my own fusion of ideas from cultural-historical psychology and cognitive science as a kind of existence proof of the potential value of inter-disciplinary dialogue.

Identifying and Engaging 'Disengaged' and 'Disruptive' Students
Ted Cole
International Journal of Emotional Education , 2009,
Abstract: This paper outlines concerns in the UK about young people who are disruptive in class and/or disengaged from the normal educational process. After discussing who these children are and estimating their numbers, the paper examines recent research on how best to meet their needs. This research indicates the appropriateness of the UK government's recent softening of its position on 'inclusion'. The studies cited indicate that far more can be done in 'normal' school settings to promote engagement but that special provision can sometimes be more appropriate. If social inclusion as adults is the overarching aim, what matters more than the physical location of the education offered are the qualities, skills, commitment and energies of the professionals involved. The values of staff, the quality of their relationships with the children and young people, and their imaginative, flexible delivery of appropriate curricula are crucial, as is the need to support these professionals in their demanding task.

Travesías peligrosas: los caminos hacia la ciudadanía
Cole, Phillip
Arbor : Ciencia, Pensamiento y Cultura , 2010, DOI: 10.3989/arbor.2010.744n1221
Abstract: In this paper I argue that citizenship and immigration policy in the United Kingdom, and other European powers, is informed by a postcolonial anxiety, informed by their colonial history. As far as the United Kingdom is concerned, the traveller from western Europe is civilized, and so welcome with no restrictions on access to the territory and with a shared European Union citizenship. The traveller from eastern Europe is less welcome. Travellers from beyond the European “frontier” face even more restrictions if they journey to the United Kingdom seeking national citizenship. Their journey has grown more hazardous during recent years, physically, politically and legally. While liberal political theory has “forgotten” its colonial past and writes about a world in which colonialism and slavery never happened, the UK’s immigration and citizenship regulations seem unable to forget either the past or the colonial narrative that shaped how it was understood at the time. This paper examines the most recent developments in the UK’s citizenship and immigration legislation and their likely future development against this background. En este artículo sostengo que la política de ciudadanía e inmigración en el Reino Unido, y en otras potencias europeas, está fundada en una ansiedad postcolonial, heredera de su historia colonial. Por lo que respecta al Reino Unido, el viajero de Europa occidental es civilizado y, por tanto, bienvenido, sin ninguna restricción de acceso al territorio y con la ciudadanía de la UE compartida. En cambio, no es tan bienvenido el viajero procedente de Europa del este. Los viajeros de más allá de la “frontera” europea se enfrentan incluso a un mayor número de restricciones si viajan al Reino Unido buscando la ciudadanía nacional. Su viaje se ha hecho más peligroso durante los últimos a os tanto físicamente como en términos políticos y legales. Mientras que la teoría política liberal ha “olvidado” su pasado colonial y escribe sobre un mundo en el que el colonialismo y la esclavitud nunca sucedieron, las regulaciones sobre inmigración y ciudadanía en el Reino Unido parecen incapaces de olvidar el pasado y la narrativa colonial que determinaron cómo dicho pasado fue comprendido en su momento. En este artículo examino los desarrollos más recientes en la legislación de ciudadanía e inmigración del Reino Unido y su probable desarrollo futuro en contraposición a estos antecedentes.
