I think that the battles among the principle characters started off being good for the development of broadcasting and broadcast technology. Leading the discussion was Dr. Lee de Forest, who media historians described as inventive, competitive, and ambitious starting from childhood. If it weren’t for his competitive nature and having people to compete with, i.e. Fessenden and Armstrong, he would not have continued his research and experiments into the development of broadcasting. Edwin Howard…

As we approach the summer of 2016, the issue of immigration in the Western world has yet to lose momentum; whether Donald Trump is arguing to build a wall on the Mexican border in the U.S. or European parties against immigration are gaining traction, it’s become clear that opposition to multiculturalism is currently rampant. German chancellor Angela Merkel is under fire for the number of refugees being let into this country; but perhaps her actions are serving one of her oldest goals, true…

Is the radio still one of the major devices? And what did the invention of the radio make possible for us? Radio made the communication over distance faster, it brought entertainment to the people’s houses, cars and it made live sessions possible. We have to ask ourselves what the radio waves might do to our body. Radio waves are made of two type’s, electrical and magnetic energy. (Steve Parker, “How Radio Works”) Nobody knew how it will affect the human body. They are largely unaffected by day…

The emergence of modern media technologies has revolutionized the way humans conduct their daily lives. The evolution of media technology has and will continue to impact the information we consume, how we consume it and how that content is created. Being and individual born in the 90s, I have witnessed massive innovation take place on a global scale that has impacted the media technologies I use. As a toddler, much of the media entertainment I was exposed to was derived from clunky TV’s,…

Porter’s Five Forces Model of Competition The five forces analysis addresses industry factors affecting competition within the areas of rivalry, barriers to entry, bargaining powers of suppliers and buyers, and the threat of substitutes. For SiriusXM to remain competitive within the radio broadcast industry, they must carefully monitor and address each of these forces. Rivalry Intensity – (Strong). Rivalry within the radio broadcast industry is a strong force, as many options are available to…

Due to different media forms, New Zealand has experienced numerous transformations over time. There is a range of different media forms such as television and print media, however radio is an important one to be discussed, along with the negative impacts it has brought through the transformations. The transformations include deregulation, privatization and commercialization. It is important to consider how these transformations have then in turn negatively affected the media’s ability to…

INTRODUCTION Millimeter wave therapy is the exposure to a frequency that ranges from 30-300 GHz. This frequency is located in the radio frequency region of the electromagnetic spectrum. Due to the extremely small wavelength the frequency will only penetrate up to 2 mm of skin. In therapy the frequency is irradiated on certain parts of the tissue, depending on the specific treatment and energy it is deposited in the skin causing a variety of beneficial reactions. In the Former Soviet Union (FSU)…

the three-level inverters often need to operate with modulation indices (m) lower than 0.5 [6]- [10]. Additionally, at lower modulation indices, traction drives operating with induction motors (IMs), interior permanent magnet motors (IPMs) or synchronous reluctance motors (SynRMs) may need to provide higher reactive power, thus operating with a lower power factor (pf) [9], [11]- [17]. For example, in [9], the power factor of IPMSMs at 0.2 modulation index is shown to be 0.52. The power factor of…

used, as shown in Fig. 7. The proposed approach was tested on a system which operates at a nominal switching frequency of 6 kHz at the linear modulation index range and with 12 kHz at the over-modulation index range. The DC-link voltage…

Cognitive-behavioral therapy(CBT) is another form of therapy that showed positive maintenance of behaviors and mood swings, self-control, and cognition with individuals who have Huntington’s disease. One study on CBT introduced the idea of allowing caregivers, family members, and/or friends into the therapy process to help adapt appropriate skills for cognition and behavior management, including anxiety. Throughout this study, each patient “…received education and awareness training and were…
