For example, some of her math equations were used in a lecture series compendium called Notes on Space Technology. She began her career working with data from flight tests, but her life quickly changed after the Soviet Union launched the first satellite in 1957. In 1953, when she was back in the workforce, Johnson joined the West Area Computing section at Langley. She quickly enrolled, but left to have children. Two years later, when the college chose to integrate its graduate schools, Johnson and two male students were offered spots. After graduating with highest honors, she started work as a schoolteacher in 1937. She attended a high school on the campus of West Virginia State College by age 13, and began attending the college at age 18. Johnson showed early brilliance in West Virginia schools by being promoted several years ahead of her age, according to NASA. Although described as a behind-the-scenes sort of worker, she helped many people get promoted or become supervisors. "She discovered that occasionally it was something as simple as a lack of a couple of courses, or perhaps the location of the individual, or perhaps the assignments given them, and of course, the ever present glass ceiling that most women seemed to encounter," stated the biography.Īfter 30 years with NACA and NASA (at which point she was an engineer), Jackson decided to become an equal opportunity specialist to help women and minorities. She also tried to help other women advance in their career, according to the biography, by advising them on what educational opportunities to pursue. Her job was to extract the relevant data from experiments and flight tests. She began her career as a schoolteacher, and took on several other jobs before joining NACA.Īs a computer with the all-black West Area Computing section, she was involved with wind tunnels and flight experiments. She graduated with high marks from high school and received a bachelor of science degree from the Hampton Institute in Mathematics and Physical Science, according to a biography posted on NASA's website. Here are brief biographies of these women: Mary Jackson (1921-2005) "Hidden Figures" focuses on three computers, Mary Jackson, Katherine Johnson and Dorothy Vaughan. However, segregation policies required that these women work in a separate section, called the West Area Computers-although computing sections became more integrated after the first several years.Īs the years passed and the center evolved, the West Computers became engineers, (electronic) computer programmers, the first black managers at Langley and trajectory whizzes whose work propelled the first American, John Glenn, into orbit in 1962. Langley began recruiting African-American women with college degrees to work as computers, according to NASA. For example: Williamina Fleming is best known for classifying stars based on their temperature, and Annie Jump Cannon developed a stellar classification system still used today (from coolest to hottest stars: O, B, A, F, G, K, M.)ĭuring World War II, the computer pool was expanded. These women made discoveries still fundamental to astronomy today. In the late 19th and early 20thcentury, female “computers” at Harvard University analyzed star photos to learn more about their basic properties. The computers worked at the Langley Memorial Aeronautical Laboratory in Virginia. The job title designated someone who performed mathematical equations and calculations by hand, according to a NASA history. " Hidden Figures," a 2016 book by Margot Lee Shetterly and a movie based on the book, celebrates the contributions of some of those workers.īeginning in 1935, the National Advisory Committee for Aeronautics (NACA), a precursor of NASA, hired hundreds of women as computers. Behind the scenes, they were supported by hundreds of unheralded NASA workers, including "human computers" who did the calculations for their orbital trajectories. In the 1960s, Mercury astronauts Alan Shepard, Gus Grissom, John Glenn and others absorbed the accolades of being the first men in space.

More robust research is required to eliminate profound limitations and consider contributing factors to DSD. The DOSE VF trial showed that double sequential external defibrillation and vector-change defibrillation led to greater survival to hospital discharge for patients with refractory ventricular fibrillation and out-of-hospital cardiac arrest. However, results are consistently limited by varying protocol and small study groups and DSD success is likely multifactorial.Conclusion:The current systematic literature review indicated that no confirmed association existed between DSD and improved OHCA outcomes. Double (or dual) sequential defibrillation (DSD) has gained popularity as an alternative treatment option for patients who fail to respond to standard defibrillation attempts. Hands-on defibrillation: an analysis of current flow through rescuers in direct contact with patients during biphasic external defibrillation. DSD is offered as a potentially feasible RVF treatment strategy throughout. double sequential in adult out-of-hospital cardiac arrestīackground:Refractory ventricular fibrillation (RVF) in out-of-hospital cardiac arrest (OHCA) poses a significant challenge to paramedic teams and is further confounded by an absence of specific guidance on the management of this patient category.Objective:To conduct a systematic literature review to determine whether double sequential defibrillation (DSD) improves patient outcomes in adult OHCA.Methods:Electronic searches of CINAHL, MEDLINE and AMED databases were carried out, using EBSCOhost (2017) and a subsequent filtering process.Results:Three case series and two cohort studies provided the highest category of evidence to evaluate. Dual sequential external defibrillation (DSED) is the process of near simultaneous discharge of two defibrillators with differing pad placement to terminate refractory arrhythmias. Double external defibrillation (DED) is the application and administration of transthoracic electrical currents from two defibrillator devices to a single patient experiencing a single type of lethal dysrhythmia during cardiac arrest, known as refractory ventricular fibrillation (RVF). Bad recordings will be unbearable to listen to, and may not be as relaxing. If we pair KEF LS50 Meta with a bright-sounding amplifier, the overall sound delivery could be too clinical and can easily cause listener fatigue. This is where we need to be cautious when pairing them with an amplifier, as one of the greatest strengths may become its greatest turn-off. There are really revealing but fortunately not too clinical. With superb stereo imaging and precision, KEF LS50 Meta is truly a world-class studio monitor for this price point. Insightful and refined, no matter how comprehensive the music is, the soundstage will always be cohesive and never muddle. Other than the low-frequency, the high and mids are exceptional, with no qualms at all. The bass doesn’t go as deep and is not as impactful which is expected from such compact speakers. The bass is detailed, rich, and accurate, you will be able to tell the difference between various percussion instruments. KEF LS50 Meta reproduces more details and clarity than its predecessor, making all instruments sound so natural and clear. More Details at Amazon – KEF LS50 Meta (Carbon Black) The KEF LS50 Meta delivers you a music presentation as faithful and close to what the artists have intended. The sonic transparency is impeccable, you won’t miss a single musical detail as everything about your favorite tune will be revealed with crystal clear clarity and finesse. We already know that KEF LS50 is designed to be a passive studio monitor and the LS50 Meta is no exception. Since the visual aspect of KEF LS50 Meta is absolutely no issue, let us now check out the sound quality. The speaker itself looks absolutely gorgeous, the stylish aesthetic design and color options allow it to blend in well with most modern amplifiers. The frequency response is 79Hz – 28kHz (☓dB) and the actual range is 47Hz – 45kHz (-6dB), we will stick with the frequency response when searching for the best matching amplifiers to pair with KEF LS50 Meta. The rear port will help supplement the bass output of the speaker though. From the size of the mid/low driver cone and the size of the speaker itself, we already understand that it won’t be able to reproduce high bass output and move a lot of air in the room as compared to bigger speakers such as floor-standers. Like its predecessor KEF LS50, the LS50 Meta also uses a Uni-Q Driver Array driver which consists of a 25 mm (1 inch) vented aluminum dome tweeter situated right at the center of a 130 mm (5.25 in.) aluminum cone.

The Duran Duran blog offers snippets of life on the road, video, product updates, event information and random insights into the band members. Personal and business blogs often come with a theme or a plan and while let’s face it, not everybody lives the life of a rock star travelling the globe it’s not too difficult to look at new ways of entertaining readers or displaying a little personality as appropriate. You should also decide which social media channels you’ll be using for your event and invite people to tweet, like, pin or share as appropriate but plan and don’t let it just happen as you’ll be diluting the coverage if you don’t. Decide on your hashtag at the planning stage and make sure attendees and everybody connected with the event is aware of it from the start. We know businesses are increasingly adopting hashtags for their events but all too often we see a number of different tags in use or that twitter gets all the attention whereas despite its phenomenal growth, twitter still lags considerably behind facebook in the numbers. They also suggest that their fans RSVP via the events option on Facebook so that friends of fans know exactly who’s going to a gig that night. It’s not unusual of course for the tag to trend ensuring everybody knows exactly who’s in town that night. Throughout the world tour the #duranlive tag has been used on twitter, streamed on to a screen at the back of a stage and enabling all of the fans in the auditorium of the night to participate or send a message to the band. Social Media should be integrated with events Nothing is more off-putting than constant sales messages, think engagement first and sales second. In business brands all too often focus on trying to sell to their followers, use their example and get to know people first – sales will come once people learn to trust you or build a relationship with you. Simon it would appear aims to entertain as this column which offers a round-up of his quirky tweets highlights! John tends to engage with the fans on anything from his autobiography to world events. Two of the band can frequently be found tweeting – John Taylor and Simon Le Bon – each with their very own unique style. So, apart from their world tours and ability to move with the times in their music, we’re looking at digital media lessons any business could take from Duran Duran! We tend as businesses to look to international brands, particularly in the FMCG or technology sectors as examples of how to do Social Business right but few articles appear in relation to the music or movie industry as all too often the updates we see from “celebrities” are in fact part of a perfectly polished plan from a PR or Social Media team ensuring that their clients best side is on show at all times.

We discuss these findings in terms of design recommendations for bare hands interactions that involve grasp-and-release tasks.Īlbert W, Tullis T (2013) Measuring the user experience: collecting, analyzing, and presenting usability metrics. (e) Some visual feedback is always preferred by users than none in both VR and desktop. The results can be summarized into: (a) user performance is significantly better in the VR configuration compared to the desktop (b) coloring techniques for visual feedback (‘object coloring’ and ‘object halo’) are more usable than ‘connecting line’ regardless of UI (c) in the VR, coloring techniques remain more usable, while in the desktop interface the ‘shadow’ technique is also usable and preferred by users, (d) the ‘connecting line’ technique often distracts users from grasp-and-release tasks on static targets. Participants (n 32) performed four trials × five feedback techniques × two UI (user interface) configurations, i.e., a total of 1280 trials. A software test bed was developed for two interface configurations: using the Leap Motion controller alone (desktop configuration) and using the Leap with Oculus Rift (virtual reality (VR) configuration). The techniques are ‘object coloring,’ ‘connecting line,’ ‘shadow’ and ‘object halo.’ The usability was examined in terms of task time, accuracy, errors and user satisfaction. This paper presents a controlled usability evaluation of four common visual feedback techniques in grasp-and-release tasks using bare hand interaction (BHI). For BHI to realize widespread adoption, interaction techniques for fundamental operations, like grasp-and-release, need to be identified and optimized. Bare hand interaction (BHI) allows users to use their hands and fingers to interact with digital content without any attached devices or accessories.
