Uf, por fin le ha gustado alguno de mis dibujos al tutor (oh, señor todopoderoso, más comúnmente conocido como Javier Peña).

Aquí os dejo lo que le he enseñado hoy, aunque todavía queda realizarle varios retoques para hacerlo más presentable.

A ver qué os parecen.

Desde que vi la presentación de Google Wave este verano, la idea de desarrollar mi PFC usando la API que da Google me ha rondado bastante.

El problema principal entonces (ahora tengo otros problemas principales) era tener alguna idea un poco original y que me apeteciera implementar. En realidad, no me había dado cuenta nunca de lo difícil que es que se te ocurra una idea cuando lo intentas de forma activa. Al final, como suele pasar, se me ocurrió algo mientras hacía otra cosa. En mi caso, conducir.

Pero no, no tiene nada que ver con coches, ni con conducir Y de momento, no voy a desarrollar la idea puesto que tengo que madurarla y darle forma antes de poder presentarla a algún profesor para que me lo coja como proyecto.

La idea de hacer un blog para llevar el seguimiento del proyecto surge de la necesidad que tengo de organizar mis ideas en sitios que no pueda destruir o fragmentar accidentalmente, ya que cuando me pongo a trabajar en local, al final tengo trabajo repartido por 3 ordenadores distintos y sin ningún tipo de orden.

Iré actualizando las páginas a medida que pueda contar más cosas

Seguramente esta pregunta nos la hacemos todos los ingenieros cuando nos llega la hora de comenzar el Proyecto Fin de Carrera (PFC). Una de las cosas que aprendí de la asignatura de Proyectos, es que tener claros los objetivos y planificación del mismo es un punto muy importante si queremos garantizar el éxito. Cambiar de objetivos en mitad del desarrollo es algo muy costoso y muchas veces hasta resulta inviable.

Por este motivo, debemos empezar por ahí, por fijar los objetivos y tomar decisiones que sean claves para el desarrollo del proyecto. Aunque también es cierto que si nos podemos permitir el lujo de probar antes de tomar una elección, esto siempre nos ayudará a decidirnos.
Bien, mi proyecto se basará en OpenCV, estará escrito en C/C++ y ejecutable en la plataforma GNU/Linux.

OpenCV es un conjunto de herramientas para el tratamiento de imágenes en tiempo real sobre ordenadores orientado a visión artificial. Es decir, OpenCV nos ofrece facilidad para operaciones típicas de este campo como pueden ser la detección de objetos, el seguimiento de objetos, reconocimiento facial, etc.

OpenCV está escrito en C/C++ y optimizado para su uso en tiempo real, pudiendo mejorar su rendimiento con las Primitivas de Rendimiento Integradas de Intel ( IPP, específicas para procesadores Intel) que no son libres, sino que Intel las vende para fines comerciales.

Se puede trabajar con OpenCV con varios lenguajes de programación como Python a través de bindings, pero se recomienda C/C++.

A lo largo del desarrollo del proyecto volveremos a hablar de OpenCV.

President Barack Obama leaves a Presidential coin at the gravesite of 19-year-old Medal of Honor recipient, Specialist Ross McGinnis, who is one of two Medal of Honor recipients memorialized at the cemetery from the wars in Iraq and Afghanistan.

Daily News/James Gordon Meek—He didn’t introduce himself. He didn’t have to.

President Obama simply stuck out his hand and asked for my name as he stepped toward me amid a bone-chilling drizzle in the Gardens of Stone.

This was Section 60 of Arlington National Cemetery. I wasn’t there as a reporter, but to visit some friends and family buried there when Obama made an unscheduled stop – a rare presidential walk among what Lincoln called America’s “honored dead” – after laying a Veterans Day wreath at the Tomb of the Unknowns.

President Obama extends a hand to James Gordon Meek of the Daily News Washington Bureau.

What I got was an unexpected look into the eyes of a man who intertwined his roles as commander in chief and consoler in chief on a solemn day filled with remembrance and respect for sacrifices made – and sacrifices yet to be made.

I’m sure the cynics will assume this was just another Obama photoop.

If they’d been standing in my boots looking him in the eye, they would have surely choked on their bile.

His presence in Section 60 convinced me that he now carries the heavy burden of command.

I had stopped at Arlington to see the resting place of Ken Taylor, Ed Lenard and Dave Sharrett. Ken and Ed survived their service, in World War II and Korea, and died as old men. Dave did not leave Iraq alive. He was 27.

Obama arrived just before noon at the serene Section 60, where many of the dead from Iraq and Afghanistan are buried together – and where many more heroes will undoubtedly be laid to rest before this President leaves office.

It’s a section typically bustling with those visiting loved ones. Every time I go there, more and more graves have been dug into the earth.

The President and First Lady Michelle Obama emerged from their armored limousine hatless in the frigid downpour and took a slow stroll into the soggy rows of white marble headstones.

They stopped first at the grave of Medal of Honor recipient Ross McGinnis, an Army private who threw himself on a grenade in Iraq three years ago to save four buddies.

A sad-faced woman reached for Obama’s hand and pointed him to a nearby plot.

The face of another woman – who had grimly sat in a folding chair for hours next to a headstone she’d arranged flowers around – suddenly broadened into a smile as she stood to embrace Obama and thank him for paying his respects.

She was so overcome with emotion that a soldier from the Army’s Old Guard had to console her afterward.

Gravestone of Pfc. David Sharrett at Arlington National Cemetery

The President patted backs of a dozen other Gold Star relatives and troops visiting buddies now in the ground.

He gave hugs. He shook wet, chilly hands. He wanted to know something about each fallen warrior.

He began to slowly trudge back toward the motorcade – and to another White House huddle with his war council, which is advising him whether to send up to 40,000 additional troops into harm’s way in Afghanistan.

And then Obama noticed a tall, bearded figure. He probably didn’t see the mud-caked combat boots I trudged around Afghanistan in a few years ago.

“What’s your name?” a somber President asked as he extended his hand.

“James Meek, sir,” I replied, struggling to pull off my wool glove and pull my hood back from my head. “I’m here visiting a friend, Pfc. David H. Sharrett II, who was killed in Iraq last year.”

Con esta entrada queda inaugurado el blog LanderPFC en el que escribiré acerca de mis avances, dudas o problemas que surjan en la elaboración de mi Proyecto Fin de Carrera.

El Proyecto Fin de Carrera está incluido en mi plan de estudios como una asignatura de 3º de Ingeniería Técnica de Telecomunicaciones, especialidad Sonido e Imagen.

A grandes rasgos el proyecto se basa en crear un programa informático que sea capaz de analizar las imágenes que le llegan desde una webcam y hacer seguimiento (tracking) de un color destacable de forma que creemos una especie de pizarra virtual. Este tipo de proyectos pertenece al área de la realidad aumentada (AR), y usará las librería de código abierto OpenCV diseñadas para visión por ordenador, con un sinfín de aplicaciones.

Dentro de los departamentos de la Universidad de Extremadura (UNEX), este proyecto pertenece al de Teoría de la Señal y Comunicaciones (TSC) y mi tutor del proyecto es Pedro Núñez.

¡De momento esto es todo pues acabo de comenzar!

Skip the Non-Stick

Non-stick cookware has been popular because, well, it’s non-stick — very convenient to use and clean. But it also emits toxic fumes when overheated. Environmental Working Group recommends that you choose safer cookware to reduce the risk of inhaling toxic particles when you let that non-stick pan get a little too hot. And who doesn’t do that occasionally?

• Why you should skip the non-stick
• What safer cookware to choose
• How to cook with non-stick if you’re ’stuck’ with it
• Other ways people are exposed to PFCs, and how to avoid them

Non-stick surfaces are aluminum pans coated with a synthetic called polytetrafluoroetheylene (PTFE), also known as Teflon, a DuPont brand trademark. Learn more about Teflon and its perfluorinated chemical “family” (PFC’s) in our chemical dictionary.

Toxic fumes from the Teflon chemical are released from pots and pans at high temperatures, potentially killing pet birds and causing people to exhibit flu-like symptoms (called “Teflon Flu” or, as scientists describe it, “Polymer fume fever”). Ingesting particles that flake off scratched non-stick cookware isn’t toxic because solid PTFE flakes are inert.

Manufacturers’ labels often warn consumers to avoid high heat when cooking on Teflon. But EWG-commissioned tests conducted in 2003 showed that in just two to five minutes on a conventional stove top, cookware coated with Teflon and other non-stick surfaces could exceed temperatures at which the coating breaks apart and emits toxic particles and gases.

See a graphic of what happens at to Teflon at various temperatures.

Health dangers: When you breathe kitchen air polluted with fumes from overheated Teflon, you’re at risk for developing flu-like symptoms (yes, “Teflon flu”). The long-term effects of routine exposure to Teflon fumes, and from Teflon flu itself, have not been adequately studied.
PFCs have been found in nearly all Americans tested by federal public health officials. Chemicals from this family are associated with smaller birth weight and size in newborn babies, elevated cholesterol, abnormal thyroid hormone levels, liver inflammation and weakened immune defense against disease.

Environmental hazards: Manufacturing PFCs and the consumer products that contain them poses great risks to the environment and wildlife. The U.S. Environmental Protection Agency says PFCs present “persistence, bioaccumulation, and toxicity properties to an extraordinary degree.”

While there are a growing number of new cookware options on the market, we don’t know enough about them to know if they’re safe — even if they’re advertised as “green” or “not non-stick.” We continue to recommend cast iron and stainless steel cookware as safer options for stove-top cooking, and oven-safe glass for baking. These safer pans might be a little harder to clean, but your health is worth it.

Stainless steel is a terrific alternative to a non-stick cooking surface. Most chefs agree that stainless steel browns foods better than non-stick surfaces.
Cast iron remains a great alternative to non-stick cooking surfaces. Lodge, America’s oldest family-owned cookware manufacturer, refers to its cookware as “natural non-stick.” Cast iron is extremely durable and can be pre-heated to temperatures that will brown meat and will withstand oven temperatures well above what is considered safe for non-stick pans.

• Never preheat nonstick cookware at high heat — empty pans can rapidly reach high temperatures. Heat at the lowest temperature possible to cook your food safely.
• Don’t put nonstick cookware in an oven hotter than 500 degrees.
• Use an exhaust fan over the stove.
• Keep pet birds out of the kitchen — the fumes from an overheated pan can kill a bird in seconds. Learn more here.
• Skip the self-cleaning function on your oven. It cleans by heating to high temperatures, which can release toxic fumes from non-stick interior oven parts.
• Choose a safer alternative when buying new cookware.

PFCs are ubiquitous — both in and out of the kitchen. They are widely used as water, stain and grease repellents for food wrap, carpeting, furniture, and clothing. They keep food from sticking to pots and pans, repel stains on furniture and rugs, and make the rain roll off raincoats.

If you want to avoid PFCs in more places than your cookware, download our Guide to PFCs to reduce your exposures further.
