The progression of the tablet computer

To say that the tablet has been on a rollercoaster journey over its lifespan would be something of an understatement. This is a type of computer that was written off by some quarters when it first hit the mainstream market, while some lauded it as one of the biggest advancements in computers. Suffice to say, sales of the iPad have proven that tablets certainly made it and while some have suggested that mobile phones might make them obsolete for younger generations, this appears to be some time away. For now, we can focus on how tablets have transformed day-to-day life. Whether it’s at home on the sofa, or devices using Aegex Technologies in a hazardous environment – they’ve made life a whole lot more convenient. Now, we’ll take a look at some of the major milestones of this device to highlight its progress in-detail.

Importance of Renewable Energy and Types of Renewable Energy Resources

Today, the majority of the world is currently dependent on various sources of fossil fuel, such as coal, gas, or oil. These resources are finite in nature, and the process of unearthing and using them is very damaging to the environment as a whole. Renewable energy is energy taken from sources which don’t run out, such as the sun, the wind, and the sea. Though we are still at the beginning of our journey into how to use renewable energy, we have already made huge strides in harnessing it. One way we have moved forward in harnessing renewable energy is by the use of feedback actuators, or linear actuators, in our set ups. Solar panels in particular have benefitted from this, as they have been able to pick up much more energy than they could before. Linear actuators have made solar panels much more moveable, so they can follow the…

Running remote host Weka experiments

Previously we have tried to run weka server to utilize all cores of processor in classification tasks. But appears that wekaserver works only in explorer for classification routines. For more advanced machine learning there is more flexible tool – experimenter. Weka server doesn’s support this area. So what to do if you want more performance or simply utilize multi-core processor of local machine. There is a way out, but it is more tricky. Weka has ability to perform remote experiments that allow spreading the load across multiple host machines that have Weka set up. You can read the documentation of remote experiment on Weka wikispaces, but in some cases it may be somewhat confusing. It took time for me to figure out some parts by trial and error. The trickiest part is to set everything up and prepare the necessary command to be run before performing remote experiment. So lets…

Utilizing multi-core processor for classification in WEKA

Currently WEKA is one of the most favorites machine learning tools. Without programming skills you can do serious classification, clustering and big data analysis. For some time I’ve been using its standard GUI features without thinking much about performance bottlenecks. But since researches are becoming more complex by using ensemble, voting and other meta-algorithms that normally are based on multiple classifiers running simultaneously, the performance issues start becoming annoying. You need to wait for hours until task is completed. The problem is that when running classification algorithms from the WEKA GUI, the utilize a single core of your processor. Such algorithms as Multi-layer Percepron running 10 fold cross-validation is calculating one cross fold at the time on one core taking long time to accomplish: So I started looking for options to make it use all cores of processor as separate threads for each fold of operation. There are couple options…

How Modern Technology Has Helped Improve Weather Forecast

On October 17th 2014, the hurricane named Gonzalo hit the island named Bermuda. It did severe damage by knocking down power lines, many trees, and completely destroying access to many, many roads. However, due to early warnings Bermuda residents were able to avoid the disaster areas. The warnings were so effective that not one death or even serious injury was reported. It’s common knowledge that storms can be hard to predict, because there are so many factors. It is nature, so it’s very difficult to see what all the potential factors would be for a storm because so many different things can develop, and so quickly. Still, scientists and weather forecasters are getting much more accurate and efficient at predicting the weather. The weather systems these days are looked at supercomputers. These computers use special algorithms to predict the weather patterns, and also store new data. Or you can find…

Taking The Plunge Into Alternative Energy

Last year was when my wife and I moved to Montana, found a comfortable home sitting on several acres with a beautiful view of the mountains. The only problem was that the property was off the grid. In fact, everybody in the subdivision produced their own power including the local bed and breakfast. It does not mean that the house was primitive. It has a wind turbine, solar panels, a generator, a battery bank and inverter, as well as a full range of appliances including a dishwasher, propane furnace, satellite TV, stove, refrigerator, and even a washer and dryer. I had previously run a cogeneration power plant prior to coming to Montana, so I was not too worried about producing my own electricity, so we ended up buying the property.

Why Ethanol is a Fantastic Fuel and Source of Energy

As the modern world moves towards a renewable energy future, ethanol fuel is becoming more popular. And even though it’s not perfect, it presents a sustainable future that doesn’t cause pollution. So, here is a look at why ethanol fuel is the big focal point all over the world. Ethanol Fuel Is More Affordable Given the fact that almost every country is in a position to make their own ethanol fuel, it makes it the most affordable energy source. Basically, if a country can grow sugar cane, corn, or grains, they can start producing ethanol. And when you compare it to conventional fossil fuel, which places huge pressure on developing countries as well as those that produce it, ethanol is the logical next step. In fact, it is a clean energy source that can help to build struggling economies. According to Wall Fireplace Pros, this has led to a significant…
