Sitios web útiles

Easel.ly: Muy bueno para crear infografías online. Muchas plantillas donde elegir, y una mecánica basada en el drag & drop a la que quizás cueste un poco adaptarse. Además, guarda nuestros archivos en su propia nube, por lo que podemos interrumpir el trabajo y retomarlo después. La con-trapartida es que a la hora de exportarlos sólo permite hac-erlo en jpeg, se echa de menos la opción directa en PDF. Así y todo, una de las webs útiles para salirse de los informes antiestéticos.

Similar Sites: Básicamente sirve para encon-trar webs similares en cuanto a temática a una que introduzcamos. El funcionamiento no puede ser más sencillo: introducimos el nombre de una web en el cajón de búsqueda, y aparece una lista de-scendente de webs similares según el porcentaje de relación. He hecho unas cuantas pruebas con webs de dife-rente temática, y lo cierto es que funciona bastante bien.

Online OCR: Si alguna vez te diste cabezazos contra la mesa por tener que transcribir un texto ya impreso, no te los volverás a dar gracias a esta web. Permite subir textos escaneados o fotogra-fiados, y su sistema lo detectará (tiene 32 idiomas de reconocimiento), y nos lo devolverá en HTML, Word, Excel, texto plano, etc. No hace falta ni que nos registremos para empezar a usarlo, aunque en ese caso tiene la limitación de 15 páginas por hora, más que suficiente para muchos casos.

Font Squirrel: Para los amantes de las tipo-grafías. Font Squirrel pone a nuestra disposición muchísimas, bien clasificadas, con una presentación limpia, y además todas ellas son gratuitas.

El diseño de la web es excelente y no está nada so-brecargado, un rara avis en las webs que ofrecen tipografías.

Office Templates: Una sección de la web oficial de Microsoft Office para descargar plantil-las para Excel, Word, PowerPoint... Básicamente, una forma de conseguir documentos más visuales y hermosos sin apenas esfuerzo.

Una de mis herramientas favoritas, las plantillas, que en el caso de las que vienen preinstaladas con Office son algo mediocres.

Join: De los creadores de LogMeIn, Join sigue una línea similar, pero más social; permite compartir lo mostrado en nuestra pantalla con otros usuarios, como hace por ejemplo Google+ en sus hangouts.

Una de las webs útiles para quienes necesi-tan hacer tutoriales en directo, por ejem-plo. La diferencia es que Join ni siquiera pide un registro previo, sino que funciona a través de emparejamientos mediante la inserción del mismo código.

Toronto team, known for human-powered helicopter, aims for land speed record

TORONTO - The Canadian team that made an aviation breakthrough last year is trying for a new milestone — the land speed record for a human-powered vehicle.

The Toronto-based team, AeroVelo, is best known for making the first practical human-powered helicopter last year, taking home a $250,000 prize that went unclaimed for 33 years.Headed by two University of Toronto alumni, the team is currently working on a bicycle that can go faster than the current world record of 133.8 km/h.

"The helicopter was huge in forming our approach here," said Cameron Robertson, one of the team leaders."We had a lot of setbacks and we had a lot of unknowns, and that's really informed a lot of the design choices we have made."Robertson said while the aerodynamics of the vehicle — a recumbent bicycle encased in a slick bullet-shaped shell — are different from the helicopter, the choices of materials and manufacturing processes are similar.

A vehicle by a Dutch team set the record at the World Human-Powered Speed Challenge last fall. Before that, Sam Whit-tingham of Quadra Island, B.C., held it for nearly 14 years and the Toronto team is hoping to take it back for Canada at this year's challenge in September.The team's vehicle is dubbed "Eta," the Greek letter widely used in science to denote efficiency, and currently has three test-riders.Only one will ride it at the record-breaking attempt at Battle Mountain, Nev.Robertson said it will likely be Todd Reichert — the other team leader, who also piloted the helicopter last year — who produces about 10 to 15 per cent more power than the others.Brian MacIntosh, a kinesiology professor at the University of Calgary, said record breakers have been pushing the peak of human fitness over the years, and bigger gains in speed can be made from better machine designs.

Not only does it make use of the powerful leg muscles, it also holds a unique advantage over other propulsion methods."In rowing, it's intermittent. You apply a force, you accelerate forward, and then, during the recovery, you slow down. In skating, it's the same thing," MacIntosh said. "In cycling, you can apply force to the cranks almost continuously."

The project will cost $120,000 in total, most of which, Robertson said, will come from donations and sponsorship.

Aerodesign ITESM Campus Toluca AZTK 029 TeamThrough the following pages, the process and results that Campus Toluca's Aero Design team performed and obtained will be presented. The work for the construction of this prototype fulfils the Aero Design 2014 Competition's mission for the Regular Class, which consists on designing and manufacturing an aircraft that can lift as much weight as possible while noticing the available power and aircraft's dimension requirements.

Design Layout and TradesFor this airplane, the team decided to use only balsa wood and light plywood for the en-tire structure of the vehicle. Previous aircrafts made by the team had used aluminum to add rigidness and stiffness to the structure; how-ever, through the mechanical analyses per-formed, the team made the decision to substi-tute aluminum for balsa and plywood in special areas. By doing this, the aircraft reduced its weight significantly without compromising the expected performance. Since previous ex-perience made the team understand that the shape of the wings had to be changed, most of the design process and analysis was focused on this elements, from designing our own air-foil to selecting the best configuration of wings.

A high lift coefficient and the capability to ac-cept great variations of the angle of attack were the two main characteristics that the team was looking for in the new airfoil.Looking through an airfoil database, two airfoils popped out for their lift coefficient: the Selig 1210 and the Wortmann FX 74-CL5-140. While the Wort-mann was the one with the highest lift coeffi-cient and kept a good performance at different angles of attack, the Selig showed a high lift coefficient as well, but needed a constant an-gle of attack to maintain a good performance.

Based on this characteristics, the team decid-ed to make a combination of both airfoils us-ing Profili, and the results were as expected, having an airfoil with a lift coefficient almost as high as the Selig's and that doesn't vary its performance due to an angle of attack change. The aircraft is divided into six main elements which were designed individually to make the best out of them for performance. Each struc-ture, materials selection and other details are explained in the following list. Elevator and Horizontal Stabilizer: the horizontal stabilizer, as well as the elevator, has 14 ribs; two of them are made of plywood and are located at the center of the body. Both of them are used as interface between the elevator and the tail´s tube, therefore a more resistant material was needed. The rest of the ribs were made of balsa wood to keep the structure light. All


Wings: for this aircraft, wings have a semi-el-liptical shape. Thinking about the easiness for packaging and assembly, the whole structure is divided into three parts: one center and two tips. Only balsa wood and plywood was used to build it, using plywood only where the bigger stresses are located. Since no aluminum tubes were used this time, thin sheets of balsa wood were put on the top and bottom side of the leading edges as if they were coverings. The purpose of this was to make it more rigid and resistant. Two of those balsa sheets were also put transversally along the wings as to help them maintain the semi-elliptical form, and they also work as traditional spars do.

Fuselage: all of the walls assemble with each other as if they were part of a jigsaw puzzle, making it simple to con-struct. The structure is completely made out of plywood. Its dimensions were reduced significantly from previous designs, based on the philosophy that it should only have enough space to store all of the essential elements of the aircraft (payload bay, motor, battery, etc.).

Developed Models The velocities that were taken into consider-ation for analysis fall in the range of velocities for take-off (1.6ft/s - 39.4ft/s). By doing this, the team was able to predict the necessary dis-tance for the aircraft to take-off depending on the weight to lift. Also, velocities between the ranges of 39.4 ft/s to 78.7 ft/s, allowed us to analyze the aircraft's behavior during flight. The team had always worked with a rectangu-lar mesh that contained the body of the aircraft to conduct CFD analysis. This model allowed us to set an inlet and an outlet for the fluid, and simulate a wind tunnel.

However, the team realized that to change the angle of attack of the aircraft, it would be nec-essary to spend more time on doing at least 10 different meshes.For those reasons, a spherical mesh for the wind tunnel simulation was proposed. As it is shown, the sphere is divided into two sym-metrical parts, representing the inlet (blue) and outlet (red) for the wind. The first runs of the analysis showed that the air was actually inter-acting with the aircraft and rapidly converged to a result. Based on this, and the fact that the team wanted more accurate results, the num-ber of elements of the mesh was increased without increasing the time investment. Also, since only take-off as a time-saving strategy.

The engineering profession is changing in response to an

increasingly globalized and

interconnected world. Increased

technological opportunities and

changing global demographics have

transformed not only the way people

interact with information, associations,

and each other, but also what those

relationships mean to them. Traditional

modes of society operation no longer

adequately address these emerging

needs and shifting expectations. To

remain competitive and relevant, and

to preclude becoming obsolete, ASME

must change to meet the challenges of

this rapidly changing world.
