The goal of ergonomics is to design jobs and tasks around the user's limitations and capabilities. To accomplish this, it is necessary for the designer to develop a clear understanding of how the equipment will be used, maintained, and even misused.

The design of the system must incorporate the worker, equipment, and environment as a whole. Task analysis is one of the basic tools that an ergonomist has to design and evaluate systems. Task analysis is any process of assessing what a user does and why, step by step, and using this information to design a new system or analyze an existing system.

The term task analysis refers to a methodology that can be carried out by many specific techniques. These techniques are used to describe or evaluate the interactions between the humans and the equipment or machines. They can be used to make a step-by-step comparison of the capabilities and limitations of the operator with the requirements of the system.

The resulting information is useful for designing not only equipment, but also procedures and training. Evaluation and design of a system using task analysis more effectively integrates the human element into the system design and operations. System design must consider the human as a component of the system to ensure efficient and safe operation. The entire system must be thought of as being comprised of the following components: human operator, equipment hardware and softwareand environment.

The mining environment inherently places many restrictions on the system design, which makes it even more important to consider these three components as a whole at the design stage to design an effective system. This systematic analysis of the tasks required of the user can result in equipment that is safer to use, easier to maintain, and operated using effective procedures.

Ideally, a task analysis should be used when designing the system. By performing a task analysis early on in the system design, the user's capabilities and limitations can be incorporated into the design of the equipment, procedures, and training. However, it does not end here. Like the overall design process, task analysis is an iterative process. After the results of the task analysis are incorporated into the system design, it is necessary to perform the analysis again to ensure that the changes do not produce an unforseen consequence.

In addition to providing useful information to incorporate into the design of system, task analysis information can be used to develop and improve the personnel and training requirements.

Task analysis also can be used to evaluate an existing system. If a problem is identified or a new piece of equipment is added, a task analysis can be used to enhance the system. There are hundreds of task analysis techniques. The mechanics used to carry out task analyses can range from observation to complex computer simulations.Despite a dip today, bitcoin has crossed into bullish territory with the biggest weekly gain since July.

In an age when data leads to economic domination, shifting control is a really impactful way to empower individuals.Bitcoin mining is performed by high-powered computers that solve complex computational math problems; these problems are so complex that they cannot be solved by hand and are complicated enough to tax even incredibly powerful computers.

The result of bitcoin mining is twofold.

Data mining

First, when computers solve these complex math problems on the bitcoin network, they produce new bitcoin not unlike when a mining operation extracts gold from the ground.

And second, by solving computational math problems, bitcoin miners make the bitcoin payment network trustworthy and secure by verifying its transaction information. When someone sends bitcoin anywhere, it's called a transaction.

Transactions made in-store or online are documented by banks, point-of-sale systems, and physical receipts. When bitcoin miners add a new block of transactions to the blockchain, part of their job is to make sure that those transactions are accurate.

With digital currency, however, it's a different story. Digital information can be reproduced relatively easily, so with Bitcoin and other digital currencies, there is a risk that a spender can make a copy of their bitcoin and send it to another party while still holding onto the original.

With as many aspurchases and sales occurring in a single day, verifying each of those transactions can be a lot of work for miners. The amount of new bitcoin released with each mined block is called the "block reward. Init was Init was 25, in it was Bitcoin successfully halved its mining reward—from This system will continue until around These fees ensure that miners still have the incentive to mine and keep the network going.

The idea is that competition for these fees will cause them to remain low after halvings are finished. These halvings reduce the rate at which new coins are created and, thus, lower the available supply. This can cause some implications for investors, as other assets with low supply—like gold—can have high demand and push prices higher.

At this rate of halving, the total number of bitcoin in circulation will reach a limit of 21 million, making the currency entirely finite and potentially more valuable over time.

mining analysis

In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to occur. First, they must verify one megabyte MB worth of transactions, which can theoretically be as small as one transaction but are more often several thousand, depending on how much data each transaction stores. Second, in order to add a block of transactions to the blockchain, miners must solve a complex computational math problem, also called a "proof of work.

In other words, it's a gamble. The difficulty level of the most recent block as of August is more than 16 trillion. That is, the chance of a computer producing a hash below the target is 1 in 16 trillion. To put that in perspective, you are about 44, times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try.

mining analysis

Fortunately, mining computer systems spit out many hash possibilities. Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing operations. The difficulty level is adjusted every blocks, or roughly every 2 weeks, with the goal of keeping rates of mining constant.

The opposite is also true. If computational power is taken off of the network, the difficulty adjusts downward to make mining easier. Say I tell three friends that I'm thinking of a number between 1 andand I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number, they just have to be the first person to guess any number that is less than or equal to the number I am thinking of.

And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the 'guess what number I'm thinking of' question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number.Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learningstatisticsand database systems.

The term "data mining" is a misnomerbecause the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction mining of data itself. The book Data mining: Practical machine learning tools and techniques with Java [8] which covers mostly machine learning material was originally to be named just Practical machine learningand the term data mining was only added for marketing reasons.

The actual data mining task is the semi-automatic or automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records cluster analysisunusual records anomaly detectionand dependencies association rule miningsequential pattern mining.

This usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics.

For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system. Neither the data collection, data preparation, nor result interpretation and reporting is part of the data mining step, but do belong to the overall KDD process as additional steps. The difference between data analysis and data mining is that data analysis is used to test models and hypotheses on the dataset, e.

The related terms data dredgingdata fishingand data snooping refer to the use of data mining methods to sample parts of a larger population data set that are or may be too small for reliable statistical inferences to be made about the validity of any patterns discovered. These methods can, however, be used in creating new hypotheses to test against the larger data populations. In the s, statisticians and economists used terms like data fishing or data dredging to refer to what they considered the bad practice of analyzing data without an a-priori hypothesis.

The term "data mining" was used in a similarly critical way by economist Michael Lovell in an article published in the Review of Economic Studies in The term data mining appeared around in the database community, generally with positive connotations. Other terms used include data archaeologyinformation harvestinginformation discoveryknowledge extractionetc.

Gregory Piatetsky-Shapiro coined the term "knowledge discovery in databases" for the first workshop on the same topic KDD and this term became more popular in AI and machine learning community.

However, the term data mining became more popular in the business and press communities. It was co-chaired by Usama Fayyad and Ramasamy Uthurusamy. A year later, inUsama Fayyad launched the journal by Kluwer called Data Mining and Knowledge Discovery as its founding editor-in-chief. The journal Data Mining and Knowledge Discovery is the primary research journal of the field.If it isn't grown, it has to be mined.

You've probably heard some variation of this saying. It is used by people concerned about the environmental effects of mineral depletionas well as people bullish on mining stocks.

Almost every commercial product has elements that started off buried beneath the earth. Here are a few things that you should know before adding mining stocks to your portfolio. Mining stocks are truly two distinct groups: majors and juniors. The majors are well-capitalized companies with decades of history, world-spanning operations, and slow and steady cash flow.

Major mining companies are no different from large oil companies, and many of the same metrics apply with a mining twist. Both have proven, and probable reservesexcept mining companies, break down profit and cost on a given deposit by the ton, instead of the barrel. In short, a mining major is easy to evaluate and easy to invest in.

The junior mining stocks are very nearly the exact opposite of mining majors. They tend to have little capital, short histories, and high hopes for huge returns in the future.

For the juniors, there are three possible fates. Although majors and juniors are very different, they are united by the one fact that makes all mining stocks unique: their business model is based on using up all the assets they have in the ground.

The catch is that mining companies don't know exactly how much is in a given deposit until it is all dug up. Reserves are evaluated through feasibility studies. These studies independently verify the worth of a deposit. A feasibility study takes the estimated size and grade of the deposit and balances it against the costs and difficulties of extracting it all.

If the deposit will fetch more money on the market than it costs to dig up, then it is feasible. If a mining major has hundreds of deposits staked or being mined, the contents of any single deposit aren't likely to shake the stock value too much. A major is the sum of all the deposits with the aforementioned goodwill tied to history. A change in the market value of a mineral that makes up a larger percentage of the deposits will have a much larger effect than a new deposit or a failed deposit.

A junior mining stock lives or dies on the results of its feasibility studies. A junior mining stock typically sees the most action leading up to, and immediately after, a feasibility study. If the study is positive, then the value of the company may shoot up. The opposite, of course, is also true. Often, a junior miner won't mine a feasible deposit to the end.

Instead, they sell the deposit or themselves to a larger miner and move on to search for another one. In this sense, junior mining stocks form an exploration pipeline that feeds the major miners in the end.

A Beginner's Guide to Mining Stocks

In this view, the big risks and rewards mostly reside at the junior mining level. As an aspiring mining investor, you're probably wondering whether you should invest in junior mining stocks or major mining stocks. The answer depends on what you are looking for.

Juniors have the potential to offer a lot of appreciation in the right market. This makes them an ideal destination for risk capitalbut hardly the best place to put your social security checks. If you are looking for a lower-risk stock with the potential for dividends and some decent appreciation, then major mining stocks may be for you.

This is a primer and as such, suffers from being overly broad and simplistic. For those who would prefer to get investing exposure to the greater mining sector rather than pick individual stocksthere are several mining-related ETFs and mutual funds available that could be added to your portfolio.

All this information is stored in a data warehouse, which is then used for Business Intelligence purpose. There are several definitions and views but all would agree that Data Analysis and Data mining are two subsets of Business Intelligence.

What is Data Analysis and Data Mining?

It is also known as Knowledge Discovery in Databases. Data Analysis — Data Analysis, on the other hand, is a superset of Data Mining that involves extracting, cleaning, transforming, modeling and visualization of data with an intention to uncover meaningful and useful information that can help in deriving conclusion and take decisions. Data Mining and Data Analysis are two distinct names and processes yet there are some views where people use them interchangeably.

This also depends on the organization or project team undertaking such tasks where this distinction is not marked specifically. To establish their unique identities, we are highlighting the major difference between them are as follows:.

A data mining specialist is still a Data Analyst with extensive knowledge of inductive learning and hands-on coding A Data Analyst usually cannot be a single person. They have been used interchangeably by some user groups while some have made a clear distinction in both the activities.

Data mining is usually a part of data analysis where the aim or intention remains discovering or identifying only the pattern from a dataset. Data Analysis, on the other hand, comes as a complete package for making sense from the data which may or may not involve data mining.

Both require different skillset and expertise and in the following years, both areas will see high demands both data, resources, and jobs.

What kind of mining industry will resurface from the ruins of the recession?

Here is the crucial role that electricity and technology played in the mining industry with observed gradual resurgence after the Covid pandemic. The mining industry is enduring a period of great uncertainty. In the face of extreme market volatility, coronavirus pandemic, stagnant commodity prices, weak demand for products, and suppressed levels of economic growth in established markets, many mining companies around the world are striving to remain buoyant.

In their quest to victoriously emerge from the recession, many miners have implemented cost-cutting initiatives aimed at maximizing customer value with fewer resources. Others have chosen to be cautiously proactive and embarked on exploration programs in a bid to boost long-term profitability. Some have turned to technology to optimize processes and facilitate existing methods.

Going lean has now become one of the central trends in the industry, as mining companies seek to concurrently reduce manpower, capital and energy intensity; exploit growth opportunities and maximize the value of their products and services.

In a highly volatile market, it is essential for mining companies to strike a balance between controlling costs and capitalizing on growth prospects and profitable opportunities. It is, therefore, imperative for them to ensure the efficient utilization of their working capital. Power generation and supply represents an area where mining operations can make significant adjustments to their capital expenditure.

Electricity remains to be the life-blood of mine sites anywhere in the world. However, with the present economic situation, mine operators cannot afford to devote, rather strap, a large portion of their scarce capital to a major expenditure, like a permanent power plant. Considering this, mine operators can instead choose to hire multi-megawatt temporary power solutions.

A consistent, dependable and sufficient supply of electricity is vital throughout the life-cycle of a mine operation.

Temporary power plants can adequately provide for the electricity needs of a mine site. They can power camp sites during pre-feasibility, feasibility and exploratory stages, and support the establishment of the mine operation after a successful exploration. They can provide power to the machinery and the processing plants, and also to the temperature-control equipment. Obviously, they can also provide the necessary power for expansion. Multi-megawatt temporary power plants could not be more relevant to the mining industry than in these times.

Renting power is a logical decision for any miner looking to effectively streamline its operations. For instance, in this economic climate, one cannot overstate the importance of precise allocation of funds and of better management of financial resources.

Gossip meaning in assamese

A key benefit of renting power is that payment schedules are fixed and regular over a contracted term. Along this line, mining companies should also be mindful of associated costs that come with building or purchasing a permanent power plant.

The cost of spare parts and ancillary which are indispensable to the continuous operation of a permanent power plants. When a mine operator goes for the rental option, all spares and ancillary will be provided by the temporary power company.

Renting multi-megawatt power plants can also prove beneficial for mining companies seeking to optimize their manpower resources. Mine operators will be happy to know that in hiring power plants, they will no longer need to employ new operators or allocate or re-train existing staff members to manage the plant. Temporary power providers will provide the necessary expert engineering services to ensure the faultless operation of the power station.

Temporary power plants can also assist in reducing the energy intensity of mine operations. Hiring power plants will preclude the chances of generators being under-utilized, because the capacity of rental power generation equipment can be increased or decreased with respect to the demand of specific mine processes.

As conventional power plants are usually specified to meet the peak demand of a particular site, they are left under-utilised when the power requirement decreases. When a power plant is running at part-load, it consumes fuel less efficiently. This will no longer be the case with rental power plants on board, thanks to their flexibility and scalability.

At the peak of the industry recession due to the Covid pandemic, many mining companies dramatically slashed their exploration budgets in the interest of making quick cost savings.
