Novelty Detection Of Machinery Using A Non-Parametric Machine Learning Approach

A novelty detection algorithm inspired by human audio pattern recognition is conceptualized and experimentally tested. This anomaly detection technique can be used to monitor the health of a machine or could also be coupled with a current state of the art system to enhance its fault detection capabilities. Time-domain data obtained from a microphone is processed by applying a short-time FFT, which returns time-frequency patterns. Such patterns are fed to a machine learning algorithm, which is designed to detect novel signals and identify windows in the frequency domain where such novelties occur. The algorithm presented in this paper uses one-dimensional kernel density estimation for different frequency bins. This process eliminates the need for data dimension reduction algorithms. The method of pseudo-likelihood cross validation is used to find an independent optimal kernel bandwidth for each frequency bin. Metrics such as the Individual Node Relative Difference and Total Novelty Score are presented in this work, and used to assess the degree of novelty of a new signal. Experimental datasets containing synthetic and real novelties are used to illustrate and test the novelty detection algorithm. Novelties are successfully detected in all experiments. The presented novelty detection technique could greatly enhance the performance of current state-of-the art condition monitoring systems, or could also be used as a stand-alone system

PENGARUH PENERAPAN PSAK 109 DAN PENGELOLAAN ZAKAT TERHADAP AKUNTABILTAS PUBLIK

Baitul Mal  Lhokseumawe merupakan salah satu Lembaga Amil Zakat yang ada di  Kota Lhokseumawe yang memiliki kewajiban sebagai pengganti BAZNAS yang bertanggung jawab dalam mengelola zakat. Dalam mengelola zakat tentulah membutuhkan penerapan akuntanasi dan manajemen yang baik. Penelitian ini bertujuan untuk melihat sejauh mana pengaruh penerapan PSAK 109 dan pengelolaan zakat terkait dengan erat kaitannya terhadap akuntabilitas sebagai pertanggungjawaban kepada publik. Pengujian dan analisis data menggunakan analisis regresi linear berganda dan uji hipotesis dengan teknik kuisioner. Hasil penelitian menunjukkan Penerapan PSAK 109 dan Pengelolaan Zakat berpengaruh secara simultan terhadap Akuntabilitas Publik. Dan secara parsial Penerapan PSAK 109 tidak berpengaruh terhadap akuntabilitas, sedangkan pengelolaan zakat berpengaruh signifikan terhadap akuntabilitas publik.   Kata kunci: PSAK 109, Pengelolaan Zakat, Akuntabiltas. &nbsp

Design and development of an implantable biohybrid device for muscle stimulation following lower motor neuron injury

In the absence of innervation caused by complete lower motor neuron injuries, skeletal muscle undergoes an inexorable course of degeneration and atrophy. The most apparent and debilitating clinical outcome of denervation is the immediate loss of voluntary use of muscle. However, these injuries are associated with secondary complications of bones, skin and cardiovascular system that, if untreated, may be fatal. Electrical stimulation has been implemented as a clinical rehabilitation technique in patients with denervated degenerated muscles offering remarkable improvements in muscle function. Nevertheless, this approach has limitations and side effects triggered by the delivery of high intensity electrical pulses. Combining innovative approaches in the fields of cell therapy and implanted electronics offers the opportunity to develop a biohybrid device to stimulate muscles in patients with lower motor neuron injuries. Incorporation of stem cell-derived motor neurons into implantable electrodes, could allow muscles to be stimulated in a physiological manner and circumvent problems associated with direct stimulation of muscle. The hypothesis underpinning this project is that artificially-grown motor neurons can serve as an intermediate between stimulator and muscle, converting the electrical stimulus into a biological action potential and re-innervating muscle via neuromuscular interaction. Here, a suitable stem cell candidate with therapeutic potential was identified and a differentiation protocol developed to generate motor neuron-like cells. Thick-film technology and laser micromachining were implemented to manufacture electrode arrays with features and dimensions suitable for implantation. Manufactured electrodes were electrochemically characterised, and motor neuron-like cells incorporated to create biohybrid devices. In vitro results indicate manufactured electrodes support motor neuron-like cell growth and neurite extension. Moreover, electrochemical characterisation suggests electrodes are suitable for stimulation. Preliminary in vivo testing explored implantation in a rat muscle denervation model. Overall, this thesis demonstrates initial development of a novel approach for fabricating biohybrid devices that may improve stimulation of denervated muscles

First of all, our thanks go to the Government of Angola for its commitment to mounting the country's first malaria survey; to the Angola Instituto Nacional de Estadi\ucc?stica, for its support of the survey even though it was embarked on important national surveys at the time; to the MOH and NMCP for their contributions towards highlighting survey needs and also for graciously donating Coartem\uc2\uae medicine to treat affected individuals; and to the National Laboratory, for its involvement in the training and microscopic analysis of blood samples. The agencies are particularly grateful to the United States Agency for International Development (USAID) and the President's Malaria Initiative (PMI) for financial and technical support for the survey, to the Malaria Branch of the Centers for Disease Prevention and Control (CDC) for inputs to the survey design, and to Macro International for substantial technical assistance offered throughout the survey.

On the relation of coloniality and masculinities in Namibia

The following is an essay that offers a critical view on the dominant gender studies’ concepts and utilizes theory from black and black masculinities studies in conjunction with the implications from the coloniality of power. The text will later touch on different aspects of black male experiences and organizational traits of Namibian masculine organization. Taking into consideration the immense transformations that were provoked by colonial occupation in the area of sexuality and identity, I intend a holistic approach that combines a critical view on capitalism and modernity under the light of the different dimensions of coloniality. As a contrast, ancestral Afrikan cornerstones are thematized as political points of articulation on which Afrikan masculinities and body-type in general can be renewed upon

La Guajira colombiana: Una economía de bonanza

La sociedad guajira, ubicada en la zona árida del caribe colombiano, considerada como expresión de diversidad étnica y convivencia, presenta una unidad de prácticas económicas que devienen de su tradición histórico-cultural de las periódicas bonanzas y sus consecuencias, altos niveles de insatisfacción en los indicadores de calidad de vida. Aspectos como la corrupción, la inequidad y la injusticia social tienen particular expresión en las formas, componente que complementa dicha tradición frente a los recursos y personas. En síntesis en La Guajira, debido a su marginalidad histórica, se ha configurado como una que hace casi imposible un desarrollo sostenido basado en el trabajo arduo.</p

Colombia y los héroes negros: un secreto a voces

Si bien la historia tradicional promovía la épica nacional como forma de exaltar los valores de los vencedores que configuraban los modelos sociales, resaltar la historia de los héroes negros tiene como propósito presentar la perspectiva de la memoria colectiva que hoy rememora los hombres notables de esta etnia como forma de evocar los valores que afloraban en épocas em que los afrocolombianos vivían en condiciones de desventaja social. Cada héroe nos da una pincelada, más allá de su epopeya singular, de las condiciones sociales e históricas circundantes que los llevó a tomar ciertas actitudes y asumir comportamientos que marcaron paradigmáticamente el telón de la memoria de los afrodescendientes. Estos personajes nos hablan tanto de los momentos de quiebre en la historia colonial, independencia, nación, abolición de la esclavitud, Guerra de los Mil Días y la Violencia, como de ciertos intersticios pacíficos en lo que hoy es Colombia
