La Codificación de Audio (también conocida como compresión de audio) es una representación digital de las señales de sonido para ser almacenadas o transmitidas por cualquier medio digital. En este proceso se busca siempre ocupar el mínimo número de bits posible para poder transmitirla por canales limitados en velocidad o bien poder almacenar muchos sonidos o música en el menor espacio posible. Todo ello se debe realizar manteniendo una calidad de sonido cada vez más exigente y, en los últimos años, permitiendo sistemas más avanzados que el estéreo que proporcionan sonido espacial. En este curso veremos los estándares más conocidos, como el MP3, así como otros formatos superiores aparecidos en los últimos años.

Unidades:

• Sección 1: Digitalización y compresión de audio, ¿cómo afecta a nuestra percepción?
• Sección 2: Escalas auditivas y tipos de compresión
• Sección 3: Estándares MPEG de compresión de audio
• Sección 4: Codificadores avanzados de audio
• Sección 5: Evaluación de codificadores

Cognitive Neuroscience Robotics is an interdisciplinary area for development of new information and robot technology systems based on understanding higher functions of the human brain, with the integration of cognitive science, neuroscience, and robotics.

This course introduces Cognitive Neuroscience Robotics with two approaches: the synthetic and the analytic approach. The synthetic approach means an engineering approach to understand human cognitive functions synthetically, trying to understand human cognitive functions by replicating them as artificial systems and putting them into social environments. Specifically, it develops artificial systems such as robots based on findings in neuroscience and physiology, and investigates how they could acquire intelligent behaviors through interaction with others and the environment.

On the other hand, human cognitive activities are investigated analytically. They are supported by higher functions of the brain and have been examined by psychological experiments or brain imaging. With the analytic approach, psychologists, cognitive scientists, and medical doctors are pursuing an understanding of the mechanism of the mind and its biological basis, with the help of engineering and philosophy.

This program will help students make a basis for interdisciplinary research by providing opportunities to understand what is undertaken in other disciplines and how to collaborate and exchange ideas with people from other disciplines. We expect many motivated students to apply.

Our lives are full of combinations. Combinatorial mathematics is just the science to deal with combinations of discrete items. As an ancient field, the history of combinatorial mathematics can be traced back over 4000 years to the age of the Great Yu in ancient China. Today, combinatorial mathematics is regarded as the basis of computer science since the algorithms in programming heavily rely on the analysis of the discrete elements.

Far too frequently, the people who have the most to say have the hardest time saying it. Many of the best minds in our society, our most talented employees and our most promising students, fail to have the impact they could because of ineffective strategies for communicating their ideas and insights to others.

This five-week refresher is geared toward experts (scientists, engineers, and other technical professionals) and will help them effectively communicate with non-scientists, usually management, to inform organizational decision-making.

Join us as we examine and learn the essential components of communication strategy.

In this engineering course, we will cover all aspects of communication acoustics, which is the way sounds travels from a source, through a channel and finally to a receiver. We will look at the different system components involved in acoustic communication, including those between humans, between humans and machines, and between machines. This includes:

• speech acoustics
• hearing acoustics
• electroacoustics
• spatial sound capture and presentation
• simulation of acoustical environments
• the human auditory system
• digital audio processing methods

You will learn from top experts in the field of communication acoustics, who are all affiliated with TU9, the nine leading Universities of Technology in Germany. Together, they have pooled their expertise in order to teach a comprehensive basic understanding and indicate current research trends to you.

After completion of the course, you will have gained a broad understanding of the involved subdomains, and will be ready to pick a specialization for future in-depth study.

La innovación es un término de moda desde hace años. No son pocas las personas que proponen la innovación como la receta mágica para todos o casi todos los males de las empresas de nuestros días, de hecho, es habitual encontrar en los medios de comunicación especializados en economía o empresas afirmaciones que vinculan la posibilidad de supervivencia de las organizaciones, al modo en que potencian, gestionan y explotan la innovación.

Sin embargo, la innovación la realizan las personas y, por desgracia, no es tan sencillo encontrar modelos que nos permitan analizar los comportamientos de nuestros trabajadores que ayudan a fomentar la innovación en la empresa.

En el curso te presentaremos un modelo de competencia de innovación compuesto de tres dimensiones que aplicaremos para que auto-evalúes tu competencia o la de las personas que están desempeñando un puesto de trabajo en tu organización. De este modo, podrás detectar necesidades y establecer acciones de formación personalizadas, así como recoger evidencias de los resultados de las posibles intervenciones realizadas para fomentar la innovación.

Composites are used in many industries today to enable high-performance products at economic advantage. These industries range from space to sports and include manufactured products for aircraft, transportation, energy, construction, sports, marine, and medical use. There are many material, economic and aesthetic advantages to using composites, but a solid knowledge of the physical properties, including the mechanics, tooling, design, inspection & repair, and manufacturing options is required for working in this medium as they are intrinsically linked.

This course provides an introduction to the fundamentals of composite materials for high performance structures from the point of view of Aerospace engineering design, manufacturing, and repair. It is designed to address critical areas of composite technologies that focus on materials, manufacturing, mechanics, design, inspection, and repair.  In this course students will learn how composite materials achieve properties of strength, weight ratios and durability that surpass aluminum in aircraft design.  For these high performance applications engineers typically rely on laminated structures, which are built up from many varying layers of ply-materials. Using this process the mechanical properties of the composite part can be tailored to specific applications resulting in significant weight and cost savings. Tailoring specific properties and designing innovative laminate structures highlights the multidisciplinary nature of this industry and how it touches the expertise of many disciplines including engineers, mechanics, and inspection specialists.

After successfully completing this course, students will be able to identify the unique characteristics of composites and understand how advanced composite structures are designed, manufactured and maintained.

Who Can Take This Course?

Unfortunately, learners from Iran, Sudan, Cuba and the Crimea region of Ukraine will not be able to register for this course at the present time. While edX has received a license from the U.S. Office of Foreign Assets Control (OFAC) to offer courses to learners from Iran, Sudan and Cuba, our license does not cover this course. Separately, EdX has applied for a license to offer courses to learners in the Crimea region of Ukraine, but we are awaiting a determination from OFAC on that application. We are deeply sorry the U.S. government has determined that we have to block these learners, and we are working diligently to rectify this situation as soon as possible.
