In addition to the UK’s civil and military aerodromes, there are hundreds of smaller, grass airfields set up by private individuals (termed ‘farm strips’). If you own suitable land, it’s possible to set up your own – of course, planning restrictions and practical considerations apply. We outline some of them here. Naturally, we suggest you obtain professional advice before flying from your land – however, if you do own a suitable portion of real estate, you can operate your aircraft from it for up to 28 days per year without planning permission, providing it’s safe to do. If the usage exceeds that, then you’ll need to apply to your Local Authority for change of use permission. Airfields operating under the 28 day rule are classified as ‘unlicensed fields’. This isn’t to say they’re illegal, but rather that they haven’t been subject to a Civil Aviation Authority survey; which quantifies and assesses approach obstacles, runway surfaces & length, and so forth. Your farm strips is therefore likely to be more challenging to fly in and out of – but, as most farm strip flyers will tell you, therein lies the challenge!

The waterfall model is a relatively linear sequential design approach for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction ("downwards" like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. The waterfall development model originated in the manufacturing and construction industries; where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in the development process. When first adopted for software development, there were no recognized alternatives for knowledge-based creative work.

So, you just bought a shiny, new, and maybe expensive, lens for your camera, and being the savvy consumer, you did your homework. You pored over customer reviews on the B&H Photo website, read online reviews splattered all over the Internet, grabbed a copy of every photo magazine that reviewed the lens, bookmarked dozens of websites, and now have the lens’s MTF curve charts burned into your retinas. Now, your lens is here and it is time to go out shooting. Honestly, not a problem. Your lens should be as good as it can be and, as photographers, we want to take photos. So, stop reading and go out and make some photographs! Still here? OK, let me tell you why you might want to test that lens yourself. The main reason is that even with today's precision computer-controlled manufacturing techniques, there are variations in each and every lens that rolls off an assembly line. This means that some examples will be better than others. Some lenses will be outstanding and others will make you wonder if all of those glowing reviews you read online were completely bogus.

In the previous chapter, we explored in depth what we mean by the tidy text format and showed how this format can be used to approach questions about word frequency. This allowed us to analyze which words are used most frequently in documents and to compare documents, but now let’s investigate a different topic. Let’s address the topic of opinion mining or sentiment analysis. When human readers approach a text, we use our understanding of the emotional intent of words to infer whether a section of text is positive or negative, or perhaps characterized by some other more nuanced emotion like surprise or disgust. We can use the tools of text mining to approach the emotional content of text programmatically, as shown in Figure 2.1.

A central question in text mining and natural language processing is how to quantify what a document is about. Can we do this by looking at the words that make up the document? One measure of how important a word may be is its term frequency (tf), how frequently a word occurs in a document. There are words in a document, however, that occur many times but may not be important; in English, these are probably words like “the”, “is”, “of”, and so forth. We might take the approach of adding words like these to a list of stop words and removing them before analysis, but it is possible that some of these words might be more important in some documents than others. A list of stop words is not a sophisticated approach to adjusting term frequency for commonly used words. Another approach is to look at a term’s inverse document frequency (idf), which decreases the weight for commonly used words and increases the weight for words that are not used very much in a collection of documents. This can be combined with term frequency to calculate a term’s tf-idf, the frequency of a term adjusted for how rarely it is used. It is intended to measure how important a word is to a document in a collection (or corpus) of documents. It is a rule-of-thumb or heuristic quantity; while it has proved useful in text mining, search engines, etc., its theoretical foundations are considered less than firm by information theory experts.

Meet the NEW Miss Lone Star. We call her "Little Miss". She was purchased for a dollar and brought back to life from what would have been a fast approaching junkyard grave. This is the refit of all refits and I am doing it all by myself. After she is splashed we travel up the East coat of the United States.

In the last few years Robot integrator T&D in collaboration with a leading supplier of natural stone, Marmi e Graniti d'Italia (MGI), has applied its technology and innovation for applications in the stone industry. One of the latest frontiers in the field is definitely the interaction between ABB robots and natural stone. Using the creation of a replica of artist Amedeo Modigliani's infamous "HEAD" sculpture in white granite, T&D explored the application of a robotic milling system to evaluate whether industrial robots are capable of the demands and challenges that processing stone requires. The results of the experiment surpassed all expectations offering a quality of cut comparable to CNC machinery. The possibility of perfecting the approach, integrating milling and polishing, is currently being explored in collaboration with ABB integrator T&D Robotics.

Through innovative design and engineering, our yachts are carefully crafted for comfort, safety and performance. Shuttleworth Design is a multi-award winning design consultancy that has been working with an international client base at the forefront of yacht design, engineering and naval architecture for more than 35 years. Shuttleworth Design grew out of John Shuttleworth Yacht Designs Ltd, a company founded by John Shuttleworth in 1980 to develop the knowledge of multihull design and engineering. John was one of the first yacht designers to develop the idea of "integrated design", a way of approaching the engineering and overall design as an integrated whole rather than a series of parts joined together. John also pioneered the use of computer aided design in multihulls and has always been a believer in research and development, often conducting tank tests and radio controlled model tests. This innovative approach resulted in boats that were lighter, stiffer, and stronger than any previous multihull designs, and put John Shuttleworth Yacht Designs firmly in the forefront of the field. John then successfully transferred this knowledge to cruising designs, an area that is under continual development. His designs have many ocean crossings behind them and Zeepoes (a 63 ft cruising catamaran) has completed two around the world voyages.

As any good web developer knows, it's important to be constantly vigilant with the handling of user data. We avoid buffer overflows and format string exploits (remember those?) by using safer languages or being careful in our C. To avoid SQL injection, we never build database queries by concatenating user-supplied data. These measures protect the integrity of the data on our servers, but what about our (non-malicious) users?

ALS booth The ALS Association’s booth at the Society for Neuroscience 2004 show Information about progress on ALS proved to be an important highlight of the 2004 meeting of The Society for Neuroscience, including reports by ALSA-funded investigators worldwide. News included gene therapy developments, stem cell research, RNA silencing, and evidence for processes underlying ALS that could point the way to new therapies. The 25,000 scientists gathered in San Diego learned about ALS by choosing among two slide sessions and several different poster sessions detailing the many different approaches underway in ALS research. Several ALSA-funded investigators notably reported on tests with a variety of compounds in animals, emphasizing ALSA’s efforts in translational research. The amount of research presented on ALS after a decade of focused attention translated into a sizeable chunk of the meeting. ALSA’s science director Lucie Bruijn, Ph.D., said, “It is encouraging to see so many invest

As the craft of Web design continues to evolve, we’re recognizing the need to develop thoughtful design systems, rather than creating simple collections of web pages. A lot has been said about creating design systems, and much of it focuses on establishing foundations for color, typography, grids, texture and the like. This type of thinking is certainly important, but I’m slightly less interested in these aspects of design because ultimately they are and will always be subjective. Lately I’ve been more interested in what our interfaces are comprised of and how we can construct design systems in a more methodical way.

Almost every new client these days wants a mobile version of their website. It’s practically essential after all: one design for the BlackBerry, another for the iPhone, the iPad, netbook, Kindle — and all screen resolutions must be compatible, too. In the next five years, we’ll likely need to design for a number of additional inventions. When will the madness stop? It won’t, of course.

We all have different habits, good and bad, in the way that we learn. For example, you may find yourself copying things out when reading rather than summarising and writing notes in your own words. We also have different preferences for the ways that we learn best. For example, some people find it much easier to understand a concept if they discuss it, whilst others find it easier to understand if they are able to see a diagram that explains the concept. Understanding your learning approaches and preferences is very important if you are going to help yourself to learn better.
