Parallel For Mac Mavericks
Bobby Morosco
I can install Ubuntu 13.10 in parallels ok and then log in. Problem is Ubuntu does an update and I get black screen / desktop such that I can't see any app windows that I open. I've tried a few of the other suggestions and they don't work for me.
Efficient velocity estimation is crucial for the robust operation of navigation control loops of micro aerial vehicles (MAVs). Motivated by the research on how animals exploit their visual topographies to rapidly perform locomotion, we propose a bio-inspired method that applies quasi-parallax technique to estimate the velocity of an MAV equipped with a forward-looking stereo camera without GPS. Different to the available optical flow-based methods, our method can realize efficient metric velocity estimation without applying any depth information from either additional distance sensors or from stereopsis. In particular, the quasi-parallax technique, which claims to press maximal benefits from the configuration of two frontally parallel cameras, leverages pairs of parallel visual rays to eliminate rotational flow for translational velocity estimation, followed by refinement of the estimation of rotational velocity and translational velocity iteratively and alternately. Our method fuses the motion information from two frontal-parallel cameras without performing correspondences matching, achieving enhanced robustness and efficiency. Extensive experiments on synthesized and actual scenes demonstrate the effectiveness and efficiency of our method.
GNU Parallel is a great utility to parallelize any computation through the command line. The book Data Science at the Command Line discusses, amongst several other things, how to use GNU Parallel to distribute your data over different machines. The toy example/ tutorial in the book makes three assumptions:
Structure_threader is a program to parallelize multiple runs of genetic clustering software that does not make use of multithreading technology (structure, fastStructure and MavericK) on multicore computers. Our approach was benchmarked across multiple systems and displayed great speed improvements relative to the single-threaded implementation, scaling very close to linearly with the number of physical cores used. Structure_threader was compared to previous software written for the same task-ParallelStructure and StrAuto and was proven to be the faster (up to 25% faster) wrapper under all tested scenarios. Furthermore, Structure_threader can perform several automatic and convenient operations, assisting the user in assessing the most biologically likely value of 'K' via implementations such as the "Evanno," or "Thermodynamic Integration" tests and automatically draw the "meanQ" plots (static or interactive) for each value of K (or even combined plots). Structure_threader is written in python 3 and licensed under the GPLv3. It can be downloaded free of charge at _threader.
Imagine, if you will, a parallel universe where a pretty blonde pop star can actually carry a tune, writes her own songs, and frets over artistic integrity. In this universe, when her record company demands more hits, she tells them to shove it and starts her own label. There's no making out with Madonna, no messy divorce, no custody battle, no 5150. Instead there's bankable talent and a credible, long-arc career. In other words, it's the anti-Britney Spears. Meet Robyn, the 28-year-old Swedish singer whose latest US release drops in April. In the mid-'90s, both were courted by the same big label to be molded into the Next Big Thing: Robyn said no. Britney said yes. It was the first choice of many, chronicled here, that would lead one to hipster stardom and the other to madness.
This is a map of shaded bathymetry with wave lines on it. The blue lines show hypothetical large wave crests propagating in to shore from the west. As the waves move into shallow water, they begin to interact with the seafloor ("shoal") and their crests slowly bend to try to maintain their roughly parallel orientation to the bottom contours. The more the waves interact with the seafloor, the more they slow down and bunch up. Wave "rays", or the pathways of wave energy, move perpendicular to the wave crests. In areas where the wave rays, and hence wave energy, diverges, the wave height decreases. Conversely, in areas where the wave rays, and hence wave energy, converges, the wave height increases. Due to the steep topography of the bedrock reef at Mavericks, the wave energy rapidly converges and the wave height rapidly increases, creating a huge wave compared to the adjacent areas.
At the center of Jefferson's plan of the university is the Rotunda, modeled after the Roman pantheon and intended by Jefferson to be used as a library. Flanking it are two parallel rows of five pavilions, each with school rooms on the lower floors and housing for the professor and his family above. All ten pavilions have a different classical facade, "so as to serve as specimens for the Architectural lectures."[2] Connecting the pavilions are single-celled dormitory rooms fronted by a colonnade, so that the students can be protected from the weather as they walk between classes. The pavilions and dormitories open onto a shared "lawn" and behind the pavilions are private yards and gardens enclosed by serpentine walls. The two outer "ranges" consist of six "hotels," or dining halls also connected by dormitories.
