Database Mining

The term database mining refers to the process of extracting information from a set database and transforming that into understandable information. The data mining process is also known as data dredging or data snooping. The consumer focused companies into retail, financial, communication, and marketing fields are using data mining for cost reduction and increase revenues. This process is the powerful technology, which helps the organisations to focus on the most important and relevant information from their collected data. Organisations can easily understand the potential customers and their behaviour with this process. By predicting behaviours of future trends the recruitment process outsourcing firms assists the multiple organisations to make proactive and profitable decisions in their business. The database mining term is originated from the similarities between searching for valuable information in large databases and mining a mountain for a vein of valuable crystal.

Recruitment process outsourcing firm helps the organisation for the betterment of their future by analyzing the data from distinctive dimensions or angles. From the business point of view, the data mining and data entry services leads the organisation to increase their profitability and customer demands. Data mining process is must for every organisation to survive in the competitive market and quality assurance. Now a day the data mining services are actively utilised and adapted by many organisations to achieve great success and analyse competitor growth, profit analysis, budget, and sales etc. The data mining is a form of artificial intelligence that uses the automated process to find required information. You can easily and swiftly plan your business strategy for the future by finding and collecting the equivalent information from huge data.

With the advanced analytics and modern techniques, the database mining process uncovers the in-depth business intelligence. You can ask for the certain information and let this process provide you information, which can lead to an immense improvement in your business and quality. Every organisation holds a huge amount of data in their database. Due to rapid computerisation of business, the large amount of data gets produced by every organisation and then database mining comes in the picture. When there are problems arising and challenges addressing in the database management of your organisation, the fundamental usage of data mining will help you out with maximum returns. Thus, from the strategic point of view, the rapidly growing world of digital data will depend on the ability of mining and managing the data.

How Gold Mining of the Past Creates New Gold for Cash

The history of gold mining and the different methods for retrieving and producing gold from the earth is quite extensive. Gold has been extracted as early as 2000BC with the ancient roman civilization and has never stopped being mined since then. While the techniques have shifted slightly over the years, the process of finding gold and converting it into wealth has remained consistent and today you can sell gold for cash with ease. It is an interesting history to examine how this gold originally came from the earth.

The Roman civilization as we know were well advanced in their approach to science and this benefited their approach to gold mining. Hydraulic mines and pumps were used to excavate gold from various regions were it was discovered. Gold discoveries prompted the capture and expansion of several territories and countries by the Roman Empire. When gold was mined it was often used to produce coinage and served as the primary source of currency or exchange for goods and services where money really represented its value. Mining with the use of gold panning techniques also most-likely goes back to the Romans. This mining technique requires a prospector to slosh sediment containing gold in a pan with water using the naturally higher density of the metal to shift it to the bottom of the pan and all other dirt or rock forced out on top.

Between the time frame of 1840 to year 2000, the capacity of gold extraction has exploded with world gold production starting at a mere 1 ton growing to currently around 2500 tons. Over this time frame the significance of gold in financial terms hasn't changed with people who continue to sell gold for cash. The increase in production, however, can be attributable to more advanced machinery and mining practices. Hard rock mining is performed when gold is found in cased in rock and requires heavy machinery or explosives to grind rock down to the point that gold can be separated. For gold that is found in veins on loose soil, rock, or sentiment a common process of either dredging or sluicing is performed. These techniques are very similar to panning by allowing the gold to settle to the bottom, but are more practical in commercial application.

These are just a few of the courses your gold may have followed over the course of its use in human history. No matter what the case, it is always possible to sell gold for cash so that it may continue to follow its path and purpose in the human world.

Derek Robertson is a financial market analyst and writer. He has written for several years for publications in print and now on many blogs and online information resources. His background in investigative journalism enables him to provide a unique and unbiased perspective on many of the subjects he writes.

He also specializes in cash for Gold and Sell Gold.

New Technique to Boost US Uranium Mining - Satellite Plants

If you study the news releases, several companies have discussed the setting up of one or more satellite plants in conjunction with their In Situ Recovery (ISR) uranium mining operations. In order to help readers better understand what exactly a 'satellite plant' is, we interviewed Mark Pelizza of Uranium Resources about how this relatively new operational technique is presently being used at the company's Texas operations. This is part two our six-part series, describing the evolution of ISR uranium mining, building upon last year's basic series on this subject.

A larger uranium deposit, such as one at Cameco's Smith Ranch in Wyoming, requires a Central Processing Plant. The 'mother plant,' as it is called in the trade, can complete the entire processing cycle from uranium extraction through loading the resin, stripping the uranium from the resin with a solvent (elution), precipitating, drying and packaging.

With a satellite plant, also known as a Remote Ion Exchange (RIX), smaller and distant deposits can also be mined and then trucked to the mother plant. With an RIX operation, the front-end of the 'milling' cycle can be begun independent of the much larger mother plant. It is the same ion exchange column found at central processing facility. The mobility factor makes RIX an attractive proposition for many of the new-breed uranium producers. Rather than piping the water and uranium across a longer distance to the mother plant for the entire processing cycle, the modular nature of RIX allows for multiple columns at each well field doing the ion exchange on the spot.

This is not a new idea, but one which has instead been re-designed by Uranium Resources and is also used elsewhere. In the early 1970s, Conoco and Pioneer Nuclear Corporation formed the Conquista project in south Texas. Uranium was open-pit mined at between ten and fifteen mines within a thirty-five mile radius and in two counties. Trucks hauled ore to the 1750-ton/day processing mill near Falls City in Karnes County.

"The trademark of south Texas is a lot of small million-pound-style deposits," Mark Pelizza told us. "I think we are heading in the right direction to exploit those small deposits." Trucking resin beads loaded with uranium is different from trucking ore which has been conventionally mined. Small, scattered uranium deposits aren't only found in Texas. There are numerous smaller ISR-amenable properties in Wyoming, New Mexico, Colorado and South Dakota.

"About half the uranium deposits in New Mexico can be mined with ISR," Pelizza said, "and the other half would require conventional mining." A number of companies we've interviewed have geographically diverse, but relatively nearby properties within their portfolio. Several companies with whom we discussed RIX have already made plans to incorporate this method into their mining operations.

The sole-use semi-trailer trucks hauling the yellowcake slurry are different from the typical dump trucks used in conventional mining. According to Pelizza, the truck carries a modified bulk cement trailer with three compartments. The three compartments, or cells, each have a function. One cell holds the uranium-loaded resin, one cell is empty and the third has unloaded resin.

As per Department of Transportation (DOT) regulations, no liquids are permitted during the transportation process. Each container run between the wellfield and the mother plant can bring between 2,000 and 3,000 pounds of uranium-in-resin, depending upon how large the container is designed. The 'loaded' cell holds between 300 and 500 pounds of resin with six to eight pounds of uranium per cubic foot of resin. Age of the resin is important, too. New resin can hold up to ten pounds of uranium per cubic foot and can decline to five pounds of uranium per cubic foot after several years.

As we found with a conventional Ion Exchange process, the RIX system is run as a closed loop pressurized process to prevent the release of radon gas into the atmosphere. The uranium is oxidized, mobilized and pumped out of the sandstone formation into a loaded pipeline and ends up in an ion exchange column at the mining site. Inside the columns, uranium is extracted through an ion exchange process - a chloride ion on a resin bead exchanges for a uranium ion. After the fluid has been stripped of uranium, it is sent back to the wellfield as barren solution, minus the bleed.

When the ion exchange column is fully loaded, the column is taken offline. The loaded resin is transferred from the column to a bulk cement trailer, which is a pressurized vessel comprised of carbon steel with a rubberized internal lining. The resin trailer is connected to the ion exchange column transfer piping with hoses. After it has been drained of any free water, the uranium-loaded resin can be transported as a solid, known as 'wet yellowcake' to the mother plant. There, the yellowcake slurry is stripped from the resin, precipitated and vacuum-dried with a commercial-grade food dryer.

Capital costs can be dramatically reduced with the satellite plants, or RIX units. "Well field installation can cost more than RIX," Pelizza noted. Often, installing a well field can start at approximately $10 million and run multiples higher, depending upon the spacing of the wells and the depth at which uranium is mined. Still, compared to conventional mining, the entire ISR well field mining and solvent circuit method of uranium processing is relatively inexpensive.

We checked with a number of near-term producers - those with uranium projects in Wyoming - and discovered at least three companies planned to utilize one or more satellite plants, or RIX, in their operations. A company's reason for utilizing this method is to minimize capital and operating expenses while mining multiple smaller deposits within the same area. Water is treated at the RIX to extract the uranium instead of piping it across greater distances to a full-sized plant. Pelizza said, "The potential for pipeline failure and spillage from a high-flow trunk line is eliminated."

Strathmore Minerals vice president of technical services John DeJoia said his company was moving forward with a new type of Remote Ion Exchange design, but would not provide details. UR-Energy chief executive Bill Boberg said his company would use an RIX for either Lost Soldier or Lost Creek in Wyoming, perhaps for both. Uranerz Energy chief executive Glenn Catchpole told us he planned to probably set up two RIX operations at the company's Wyoming properties and build a central processing facility.

"We are working on a standardized design of the remote ion exchange unit so it doesn't require any major licensing action," Pelizza said. "If you can speed up the licensing time, perhaps it would take one to two years rather than three to five years."

Data Mining vs Screen-Scraping

Data mining isn't screen-scraping. I know that some people in the room may disagree with that statement, but they're actually two almost completely different concepts.

In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to analyze information. That's a pretty big simplification, so I'll elaborate a bit.

The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. Screen-scraping was used to extract characters from the screens so that they could be analyzed. Fast-forwarding to the web world of today, screen-scraping now most commonly refers to extracting information from web sites. That is, computer programs can "crawl" or "spider" through web sites, pulling out data. People often do this to build things like comparison shopping engines, archive web pages, or simply download text to a spreadsheet so that it can be filtered and analyzed.

Data mining, on the other hand, is defined by Wikipedia as the "practice of automatically searching large stores of data for patterns." In other words, you already have the data, and you're now analyzing it to learn useful things about it. Data mining often involves lots of complex algorithms based on statistical methods. It has nothing to do with how you got the data in the first place. In data mining you only care about analyzing what's already there.

The difficulty is that people who don't know the term "screen-scraping" will try Googling for anything that resembles it. We include a number of these terms on our web site to help such folks; for example, we created pages entitled Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I suppose "scraping" is sort of like "ripping"). So it presents a bit of a problem-we don't necessarily want to perpetuate a misconception (i.e., screen-scraping = data mining), but we also have to use terminology that people will actually use.

There is No Need to Disrupt the Schedule to Keep the Kitchen Canopy and Extraction System Clean

After taking over a large and beautiful stately hotel its new owner quickly realised that the kitchen extract system would not be straightforward to maintain because the duct work for the extract system was somewhat ancient and therefore would be difficult to clean.

A prestige hotel needs to maintain a high level of hygiene as well as to minimise the risk of a kitchen fire.

So, if replacing the entire system is not an option what can the new owner do to find a solution that would meet exacting standards of cleanliness and ensure that the risk of a fire starting in the system is minimised while ensuring that the cleaning does disrupt the operation of the hotel and restaurant as a business?

Using an experienced specialist commercial cleaning service to asses the establishment, the types of food cooked, how and at what level of intensity is the first step.

It is difficult without this information to advice on how maintenance should be carried out.

The frequency of the cleaning cycle for a canopy and its components depends not only on the regularity and duration of cooking below but also on the type of cooking and the ingredients being used.

Where  the kitchen use is light canopies and extract systems may only need a 12-month cycle for maintenance and cleaning. However, in a busy hotel, kitchen activity is most likely to be heavy and the cleaning company may advise a three or four-month cycle.

Grease filters and canopies over the cookers should ideally be designed, sized and constructed to be robust enough for regular washing in a commercial dishwasher, which is the most thorough and efficient method of cleaning them yourself.

It's important to make sure when re-installing filters that they are fitted the right way around with any framework drain holes at the lowest, front edge. Of course, grease filters are covered with a coating of grease and can therefore be slippery and difficult to handle. Appropriate protyective gloves should be used when handling them.

The canopies and their component parts should be designed to be easy to clean, but if they are not, provided the cleaning intervals are fairly frequent, regular washing with soap or mild detergent and warm water, followed by a clean water rinse might be adequate. If too long a period is left between cleans, grease will become baked-on and require special attention.

No grease filtration is 100% efficient and therefore a certain amount of grease passes through the filters to be deposited on the internal surfaces of the filter housings and ductwork.

Left unattended, this layer of grease on the non-visible surfaces of the canopy creates both hygiene and fire risks.

Deciding on when cleaning should take place, and how often, is something an experienced specialist cleaning company can help with. The simplest guide is that if a surface or component looks dirty, then it needs cleaning.

Most important, however, is regular inspection of all surfaces and especially non-visible ones. The maintenance schedule for any kitchen installation should include inspections.

A regular maintenance and cleaning schedule is not impossible even in the kitchen of a hotel with an antiquated canopy and duct system with the help of a specialist commercial cleaning company to advise on how to do it without disrupting the work flow, as writer Ali Withers discovers.

The Trouble With Bots, Spiders and Scrapers

With the Q4 State of the Internet - Security Report due out later this month, we continue to preview sections of it.

Earlier this week we told you about a DDoS attack from a group claiming to be Lizard Squad. Today we look at how
third-party content bots and scrapers are becoming more prevalent as developers seek to gather, store, sort and present
a wealth of information available from other websites.

These meta searches typically use APIs to access data, but many now use screen-scraping to collect information.

As the use of bots and scrapers continues to surge, there's an increased burden on webservers. While bot behavior is
mainly harmless, poorly-coded bots can hurt site performance and resemble DDoS attacks. Or, they may be part of a rival's competitive intelligence program.

Understanding the different categories of third-party content bots, how they affect a website, and how to mitigate their impact is an important part of building a secure web presence.

Specifically, Akamai has seen bots and scrapers used for such purposes as:

•    Setting up fraudulent sites
•    Reuse of consumer price indices
•    Analysis of corporate financial statements
•    Metasearch engines
•    Search engines
•    Data mashups
•    Analysis of stock portfolios
•    Competitive intelligence
•    Location tracking

During 2014 Akamai observed a substantial increase in the number of bots and scrapers hitting the travel, hotel and hospitality sectors. The growth in scrapers targeting these sectors is likely driven by the rise of rapidly developed mobile apps that use scrapers as the fastest and easiest way to collect information from disparate websites.

Scrapers target room rate pages for hotels, pricing and schedules for airlines. In many cases that Akamai investigated, scrapers and bots made several thousand requests per second, far in excess of what can be expected by a human using a web browser.

An interesting development in the use of headless browsers is the advent of companies that offer scraping as a service, such as PhantomJs Cloud. These sites make it easy for users to scrape content and have it delivered, lowering the bar to entry and making it easier for unskilled individuals to scrape content while hiding behind a service.

For each type of bot, there is a corresponding mitigation strategy.

The key to mitigating aggressive, undesirable bots is to reduce their efficiency. In most cases, highly aggressive bots are only helpful to their controllers if they can scrape a lot of content very quickly. By reducing the efficiency of the bot through rate controls, tar pits or spider traps, bot-herders can be driven elsewhere for the data they need.

Aggressive but desirable bots are a slightly different problem. These bots adversely impact operations, but they bring a benefit to the organization. Therefore, it is impractical to block them fully. Rate controls with a high threshold, or a user-prioritization application (UPA) product, are a good way to minimize the impact of a bot. This permits the bot access to the site until the number of requests reaches a set threshold, at which point the bot is blocked or sent to a waiting room. In the meantime, legitimate users are able to access the site normally.

Top Tips for Data Mining Success

You may have trieTips for data mining successd data mining before but you seem to be lost in the maze of confusion, data overload, and a number of strange terms and icons. Do not fret, you are not alone. There may be a number of first timers who are in the same boat as you do. Stop, refocus and start all over again with the following tips in mind.

It is important that proper handling of the data mining procedure must be employed. Easy as it may sound, it can only bring in great results when it is placed in the expert hands and when done according to the right patterns and processes. This is not to say that data mining is only successful for a gifted and trained few. It means serious consideration, preparation, and training must be part of the groundwork before disembarking into it.

The most practical and tested tips are: know your desired outcomes; set expectations; assign the right personnel; avoid data dump; create a deployment scheme; develop a maintenance plan.

Know your desired outcomes

As the major proprietor of your business, you of all people should have a clear view in mind of what you really want for your business. Thus, before trying on new strategies and techniques that are recommended to you, you must know what your desired outcomes are. For instance, if your business is in real estate, you must be able to foresee which direction your market should go. Are you going up on skyscrapers or towards the horizons in the countryside? From great lengths, you go to the specifics and clearly spell out what you want and where it should be.

Set expectations

In connection with identifying your outcomes, you must also set realistic and attainable expectations. These are the very things that preclude possible obstacles and frustrations in the coming years. You can see where your business is going by web research or data mining. You can see the past and present of your competitors and you can also set your own future based on the experiences of others. It is often wise to set expectations that you have not attained before. It is like plowing and preparing the ground because you know rain is coming and it is the right time to plant and gain great harvest.

Assign the right personnel

When you find the right person as well as the right data mining service, you can cut short tiresome planning, devising and preparation. If you are in a small enterprise, you can spearhead the procedure but if you have enough staff at your disposal, choose one who is not only knowledgeable but also reliable and dedicated. You do not want someone who is only a good starter and one who would leave you hanging when the going gets tough.

Avoid data dump

Being sure of what you want can help you avoid unnecessary data. Data mining like real mining is being able to know where the gold is and is able to get it done in the most efficient and effective way. Being able to identify the legal sites and reliable, well researched information is the short cut to finding the right and exact data. It would be a waste of time and effort if you are aimlessly opening and clicking on unsure and ambiguous websites. There are a lot of links that lead you to more links and are simply making money out of others’ ignorance.

Create a deployment scheme

Like any other venture, you must also be able to delegate the task as well as the information that you gather. Since you are not a superhuman, learn to seek the assistance of others and be sure that you know who to trust. In addition, you must have a classification and segregation of the needed materials so that these will be easy to locate and analyze. In other words, order and proper organization is another tip in order to achieve success in data mining.

Develop a maintenance plan

Finally, along with orderliness and efficiency, you must see to it that you have an effective maintenance plan. What to do with old data and where to store the vital ones are concerns that need to be considered too. In addition, there is a need for a watchdog in the whole duration of your business venture. This will not only assure you of security of your data but also keep you on healthy and solid ground. This maintenance can be both a cleaning and healing spot for your business’ overall life and sustainability.

So much can be said about how to go about with your business using data mining but there is a factor that is uniquely your own. Above and beyond all these techniques and strategies, trust your instincts. You are the better judge of your desires and actions; thus, you must spend time alone in reflection, contemplation and retrospection. Being silent and alone can make you see things that are missed among all the movements and noise. Once in a while, leave the scene and look objectively at your work. Remember, there is wisdom in alienation and objectivity.
