Technical Analysis is a technique for forecasting the direction of stock prices based on past market data. Itas simplest form takes only two variables into account: 1) price, and 2) volume. At this level, Technical Analysis is an overly simplified statistical analysis of market trends, and while many people have claimed positive results, it does not stand up to the scrutiny of academic mathematicians. Historically, Technical Analysis stood in contrast with fundamental analysis, which prefers to make a more comprehensive profile of a company before predicting future trends. Technical Analysts argued that if specific company data was relevant, it would have already effected the price or volume of their stocks, and is therefore inherently included in the technical analysis anyway. Eliminating guesswork from the investment process is the goal of technical analysis. Using different data, fundamental analysis creates the same result with a different method. Technical analysis, however, gives a pure, quantitative gauge of future trends to help automate decision making. Professional Technical Analysts will likely identify atypical patternsa such as the aHead and Shoulders Patterna. When looking at a graph, this pattern depicts three peaks with the center peak the highest, and the other two approximately the same. Patterns such as this, serve as graphic indicators by which an analyst will make trading decisions. Critics argue that these patterns are not mathematically valid, but rather are the result of humanas psychological predisposition to finding patterns in an otherwise random graphical environment. The method of measuring and predicting market trends using quantitative methods may be limited. Subjective bias is evident when analysts give more or less consideration for certain statistical patterns or favor certain charting methods. Therefore, technical analysts traditionally ignore a great deal of quantitative data. Machine learning and artificial intelligence are the new frontier for both technical analysis and fundamental analysis. These computers can make the decision making process of investing automated, without consideration of how much data can be physically processed by an individual. Machine learning has no predisposition to identifying false patterns, and it is able to include disparate data, which on the surface appears to have no correlation to the trends being analyzed. Furthermore, machine learning will identify patterns at any scale. While Analysts tend to look for large (significant) trends, at the machine level, any scale is significant if a trend can truly be identified. Whether machine learning will replace Technical Analysis, or will be used as a tool to improve it, it is likely that many existing analytical paradigms will become less relevant as our tools become better, and reveal the shortcomings of our prior techniques.

Industrial vacuum cleaners are designed with two basic functions in mind - the removal of debris of all types from the floor and the removal of debris of all types from the air in the working environment. The first application was tricky, to say the least, but the specific needs were dealt with until systems and units were produced that could handle almost any type of debris from the floor of a manufacturing company.

At first, the size of the debris was a question to be dealt with. Then there were wet and dry items that needed to be dealt with simultaneously. Extremely hot or corrosive elements were added to the mix and then radioactive debris had to be taken into account. All of this debris, a bi-product of some sort of manufacturing or large-scale commercial operation, had to be dealt with by vacuum cleaner manufacturers. Often, the special requirements of a company were dealt with on a case-by-case basis at the same time as the new plant was being constructed.

Similarly, airborne debris, dust and microscopic particles of whatever was being produced in the shop had to be removed from the air, either to protect the workers or to gather and store the valuable materials to keep from losing them. Huge vacuum cleaners were mounted on rooftops, and behind the factories themselves, that resembled air-conditioning units more closely than vacuum cleaners. But they performed precisely the opposite function. Where air-conditioners cool and then pump air into the factory to keep temperatures comfortable and controlled, these huge vacuum cleaners are sucking the air out of the factories, either from the ceiling levels or from beneath the floor, filtering out the debris and keeping it accessible during cleaning.

Factories that produce fine particulate debris as part of their manufacturing process need to maintain a safe breathing environment for their workers and those companies that are refining a valuable metal need to collect the particulates for later re-use. Both functions are amply served by today’s industrial vacuum cleaners.
