Wozniak’s Predictions for Technology Trends

According to Steve Wozniak in a recent interview, the technology world is on the verge of some fairly major changes, exciting changes.

In the area of memory and chip size, Wozniak pointed to the chips used in cameras and talked about using them in other ways, inside of computers on cards. He wants to see hard drives replaced entirely with non-moving chips and cards. They offer small size, huge capacity, and lightning-fast speed, and lots of other advantages if used in the “right” way. Wozniak point out the many are using them in “wrong” ways, creating solid-state drives and memory that in his opinion are pointless. 

The advantages became clearer when he spoke about “The Cloud” later in his talk. The “cloud” is not a new concept, traditionally referring to the internet in general, but it’s taken on a new meaning recently, combining the best of the internet and the best of micro-computing and putting them together into something akin to a universal “digital bank.” So instead of everyone having unlimited storage on their own personal computers, everyone would send their information – pictures, files, videos, everything – to the “cloud” for storage. Wozniak admitted that many people are leery of the security of such concept, but he’s certainly not alone in his prognostications about the cloud, and with iTunes recently moving toward online backup and storage for individual music libraries and google docs recently allowing upload of any file type, the reality of “the cloud” becoming everyone’s digital bank is closer than many think.

 Wozniak also talked about the new organic LED screens that are soft and flexible. Instead of making them stiff like some companies do, Wozniak wants to take advantage of their flexibility. He envisions a globe made from the material, turned into a 3-D, touchable Google Earth. He loves the new, touch-ability of many tech products, and sees that market continuing to succeed, also, mixing 3-d advances with touch screens and interactive computing experiences.

 It’s obvious that Wozniak is excited by the technology that’s coming in the weeks and months ahead, and why not? The ideas and hardware that he talks about is almost revolutionary, changing the face of computing and technology as we know it.

Genetic Algorithms in Electromagnetics

January 16, 2010 Leave a comment


Description: Authors : Randy L. Haupt, Douglas H. Werner

Genetic Algorithms in Electromagnetics focuses on optimizing the objective function when a computer algorithm, analytical model, or experimental result describes the performance of an electromagnetic system. It offers expert guidance to optimizing electromagnetic systems using genetic algorithms (GA), which have proven to be tenacious in finding optimal results where traditional techniques fail.

Genetic Algorithms in Electromagnetics begins with an introduction to optimization and several commonly used numerical optimization routines, and goes on to feature:

  • Introductions to GA in both binary and continuous variable forms, complete with examples of MATLAB(r) commands
  • Two step-by-step examples of optimizing antenna arrays as well as a comprehensive overview of applications of GA to antenna array design problems
  • Coverage of GA as an adaptive algorithm, including adaptive and smart arrays as well as adaptive reflectors and crossed dipoles
  • Explanations of the optimization of several different wire antennas, starting with the famous “crooked monopole”
  • How to optimize horn, reflector, and microstrip patch antennas, which require significantly more computing power than wire antennas
  • Coverage of GA optimization of scattering, including scattering from frequency selective surfaces and electromagnetic band gap materials
  • Ideas on operator and parameter selection for a GA
  • Detailed explanations of particle swarm optimization and multiple objective optimization
  • An appendix of MATLAB code for experimentation
