Differences Between Data Analytics vs Business Analytics

Data Analytics is more technical centric than the other in terms of technical skillset as a data analyst would be doing hands-on data cleaning, data purging, finding correlations etc. A data analyst would love to dirty his hands on any of the latest tools out there and test his/her data on the tool and see what insights he/she can draw from it.

Business analytics, on the other hand, is a kind of more process-oriented / functional role where a business analyst would be looking into the day to day operations of the company. A CEO/CMO won’t understand what correlation is or what variables are really having a weight on the transform function, hence a business analyst. A business analyst should be able to interpret the data analyst terminologies and transom them to be presentable to their respective heads. A business analyst would also look into optimizing and would also be the one to call the shorts for upgrading/optimizing any models in the company/campaign.

Elicitation – A BA’s friend

Requirement elicitation is the process of collecting information from stakeholders. It serves as a foundation in documenting the requirements for application development.

There are a number of elicitation techniques to gather requirements or to collect the information from the stakeholders. Some of the requirement elicitation techniques are as follows.

  1. Document analysis
  2. Observation
  3. Interview
  4. Prototyping
  5. Brainstorming
  6. Workshop
  7. JAD (Joint Application Development)
  8. Reverse engineering
  9. Surveys/Questionnaire

GREENHOUSE GASES – Pandemic brings in the Drop

DRASTIC DROP IN GREENHOUSE GASES

Global CO2 Emissions Saw Record Drop during Pandemic Lockdown

 The wave of shutdowns and shuttered economies caused by the coronavirus pandemic fueled a momentous decline in global greenhouse gas emissions.

As infections surged in March and April, nations worldwide experienced an abrupt reduction in driving, flying and industrial output, leading to a startling decline of more than 1 billion tons of carbon dioxide emissions. That includes a peak drop in daily emissions of 17 percent in early April. For some nations, the falloff was much steeper.

At first glance, a reduction of that magnitude appears massive. In comparison, global emissions dropped 1.5% during the Great Recession in 2009.

But a deeper look shows that individual changes in behavior produce limited emission reductions. Much of the world stopped traveling, eating in restaurants and buying merchandise. It was an unmatched experiment and yet 80% of emissions were untouched.

Even an emissions drop of that scale would fall short of the 7.6% annual reductions the United Nations has said are necessary over the next decade to hold the global temperature rise to below 1.5 degrees Celsius. Continue reading

SoC

System On Chip (SoC)

A system-on-chip (SoC) is the integration of functions necessary to implement an electronic system onto a single substrate and contains at least one processor. The only real difference between an SoC and a microcontroller is one of scale.

An SoC contains multiple processing parts, memory, modems, and other essential bits and pieces manufactured together in a single chip that’s soldered onto the circuit board.

Dos and Don’t of Backyard Composting

CompostingBackyard Composting

Starting a compost bin is one of the easiest ways to reduce your household’s waste and create nutrient rich soil that can be used throughout your garden. With so many different options and styles of compost bins available these days, the best part is that a compost bin no longer has to be an eyesore in your garden and can easily tie in with your landscaping design.

Vector Graphics

An overview of Vector Graphics

Vector graphics,  consist of paths defined by a start and endpoint. These paths can be anything from a line to a series of lines that create a shape like a square or a circle. Despite the simplistic nature of a vector’s building block, paths are used to create extremely complex diagrams. Each path object carries its own mathematical statement that defines how the object should be displayed.

What Is an SVG File?

A file with the SVG file extension is most likely a Scalable Vector Graphics file. Files in this format use an XML-based text format to describe how the image should appear.

Since text is used to describe the graphic, an SVG file can be scaled to different sizes without losing quality—in other words, the format is resolution-independent. This is why website and print graphics are often built in the SVG format, so they can be resized to fit different designs in the future.

Podzolization

Podzolization encompasses the downward migration of Al and Fe, together with organic matter, from the surface areas and their accumulation in the profile’s deep areas.

This process is characterised by a strong acidity that causes the slow development of organic matter (which releases abundant organic compounds with an acidic nature) and an extreme alteration of the mineral phase (releasing abundant elements that are lixiviated by the drainage waters, while the medium is enriched with insoluble elements, such as Fe and Al, which are migrated downward by the organic compounds towards deeper horizons). In short, an eluvial horizon is formed on the surface with intense substance losses.

A process of soil formation, esp. in cool, humid regions, in which the upper layers are leached of iron, lime, and alumina, which are then concentrated in underlying layers.

The evidence that the podzolization process has developed in a soil is reflected in the profile’s spectacular micromorphology, with abundant coverings of organic matter on the sand grains in horizon Bh.

 

Hydrology and Soil

The relation between Hydrology and Soil

By: Vineeta Tawney

It is important to understand how the water and soil work in the town as well. For instance, one would want the ground to be both permeable and porous so it can store plenty of water for the plants.The hydraulic, or water, cycle as a whole is fairly self-explanatory. Water falls down to the earth through precipitation, such as rain or snow, runs down as discharge into a reservoir such as lakes, rivers, and oceans, and through evaporation, collects again in the sky as clouds. The figure below is a good visual representation of this cycle:

There are a few different types of water, gravitational, hygrosophic, and capillary. Capillary water is what plants (such as the one in the figure below) use to collect nutrients they need. This happens by the water moving up from pore space to pore space, in this case, against gravity.
There are many aquiclude wells. This means that the water comes up to the surface from the water table through its own pressure, and does not have to be pumped. The residents of this small town use these wells to water their crops, cooking, and bathing. What they are most likely unaware of, however is that if they use more water that is replaced by participation, the ground will lower and fill in the area where the water used to be held.. The wells will then dry up, and they will no longer be able to be filled. Residents will have to gather their water from the lake resting near the top of a mountain, or the ocean.
Soil is another important factor in farming. For example, if the soil is too hard or dry, or if it does not have enough nutrients than no, or very few crops will grow. A farming community needs a very lucrative soil to produce its main source of income. Following the graph below, and assuming that Trampoli has a climate similar to North Eastern United States since it has four very distinct seasons that vary dramatically in temperature, and it is near the coast, the process of the soil in Trampoli is somewhere between Poderization and Calification.
Also, looking at the soil profile below, there is a layer of soil that could be considered an ash-gray (at least if it was real). This color is from silica which is caused by a process called illuviation. This is a characteristic of soil formed by Podzolizatoin.
