If you’re new to the world of image editing, you might not have heard the terms raster image and vector image before – and there are even a few more experienced editors who could brush up on their terminology too. Vector vs Raster: What’s The Difference?.GIMP isn’t the only piece of free image editing software available, so I can point you in the direction of a couple of different options that will let you create vector images properly, with all the fun and time-saving tools that you’ll find in a dedicated vector graphics program. GIMP cannot do anything with these entities, but it can load them as paths.” – The official GIMP user manual, Section 5.7 ![]() “The SVG format handles many other graphical elements than just paths: among other things, it handles figures such as squares, rectangles, circles, ellipses, regular polygons, etc. An SVG file will probably display better in your web browser than it will in GIMP. You can open SVG files, but that’s about it. GIMP does have limited support for the web-friendly vector format SVG (Scalable Vector Graphics), but when I say limited support, I really mean it. The strokes, fills, and patterns of your shapes are all rasterized as pixels immediately, and never exist as vector data. The Paths tool in GIMP does use a Bezier curve system in the same way that vector graphics programs create shapes, but these paths are only used as a means of defining specific areas for pixel editing. GIMP is a raster image editor, which means it creates and edits pixels, not vectors. Creating vector images from pixel images is useful for a lot of different design projects, but I have to tell you right from the start that GIMP is not designed for creating vector images.

With it, anyone can add to or use the massive selection of codes to provide easy access to a world of programming possibilities.Īnother prominent feature of all Arduino boards, including the Mega, are the Arduino shields. The open-source coding terminal has a variety of features that make it accessible to both novices and programming gurus alike, most notably the IDE’s associated library of projects and other syntaxes created by the massive community of Arduino users. Like the Uno, the Mega operates in the Arduino Integrated Development Environment (IDE). Arduino Mega 2560 Pinout DiagramĪs far as other hardware on the Mega goes, it also touts four serial ports for general attachments, a USB connection (with a dedicated ATmega16U2 processor for interfacing with your computer), a reset button and a power supply port. See the graphic below for a (dare I say) mega-map of the Mega’s pins. Because of its brawnier processor, the Mega has 54 digital I/O pins (15 of which can provide PWM output) and 16 analog pins, which is almost four times that of its little brother, the Uno. Thanks to the ATmega2560 (and its associated crystal oscillator), the Arduino Mega sports 16 MHz clocking speed, as well as 256 KB of flash, 8 KB of SRAM and 4 KB of EEPROM. Voila, it worked like a charm! I would have saved a lot of time and frustration if I had known that the SMD required the ICSP header and the header was included in the kit.As stated before, the brain behind the Arduino Mega is the ATmega2560. I made up a header, soldered it onto the MicroSD Shield and placed the Shield back on the Arduino. Then I read a couple of comments on the SparkFun site about the MicroSD Shield not being able to be used with some Arduino types unless the ICSP header was installed. I then tried the shield on an Uno R3 and it worked fine.Īccording to the information provided on the Arduino site there are no differences between the R3 and SMD editions, so I thought my SMD was shot. All produced the same failure to initialize SD card message. ![]() ![]() I then tried all SD examples available on the Arduino IDE, those provided on the SparkFun site and even some found online. I then tried to run a sketch for data storage and got a failure to initialize SD card message on the serial monitor. I tried using the MicroSD Shield with the recommended Arduino R3 Stackable Header Kit installed on an Arduino Uno SMD. We recommend the Arduino R3 Stackable Header Kit. This shield comes populated with a microSD socket, red power indicator LED, and a reset button but it does not come with headers installed. The shield also includes a large prototyping area with a 13x12 grid of 0.1" pitch PTHs. Also for the libraries to work pin D8 will have to be set as an output in the 'setup()' section of your sketch. Most libraries assume the CS pin is connected to D10 this will have to be changed to D8. If you decide to use one of the many open source FAT libraries (like FAT16 or SDFat) make sure to change the code to reflect the location of the CS pin. The SCK, DI, and DO pins of the microSD socket are broken out to the ATmega168/328's standard SPI pins (digital 11-13), while the CS pin is broken out to Arduino's D8 pin. Running out of memory space in your Arduino project? The SparkFun microSD Shield equips your Arduino with mass-storage capability, so you can use it for data-logging or other related projects.Ĭommunication with microSD cards is achieved over an SPI interface. Gantt chart templates are most useful during the project planning stage. Take the place of project management once the project goes live. Note: you can prevent this by creating your Gantt chart template with project management software. If your Gantt chart template is made in a non-dynamic format, you won’t be able to adjust it as easily once you create it. Keep your project on track with easy-to-reference, clearly defined deadlines.Īutomate processes through dependencies and robust customization, especially when it’s made with supporting software. Give all stakeholders a quick, bird’s-eye view of your project. But if you create your template in a dynamic tool, you can make updates and see changes in real time. ![]() If you’ve ever seen or used Gantt chart templates in a spreadsheet before, you’ve seen how manual and time consuming it can be to change them. Some of this will depend on the tool you use. Like any project management resource, your Gantt chart template will have best case scenarios and limitations. But once it’s done, all you need to do is duplicate the template and fill in the blanks. How to use your Gantt chart template for project planningīuilding your template is the more time-consuming part. Instead, you might want to consider project management software with more functionality-for example, a tool that lets you manipulate data and input information in a space that’s accessible by all stakeholders. If you’re in a project management tool, you can directly attach your Google sheets, Kanban boards, and references (like tutorial PowerPoints) directly to your project timeline.įor more complex projects, a simple spreadsheet likely won’t offer enough customization options. The more thought you put into constructing your template, the less work you’ll have when it comes time to launch your next project.Īdd integrations and apps to support your work. For example, if the same team member always manages the budget, you can keep them assigned to the budget deliverables in your template. Be sure to include recurring dependencies and roles. ![]() Input your information into one central source of truth, such as a project management software. Attach recurring worksheets, relevant roadmaps, documents, analysis results, reporting dashboards, goals, assigned roles and processes. Gather information and relevant resources. Possible inputs include:start dates, end dates, independent and dependent tasks, milestones, roles, subtasks, and descriptions. For complex projects, you need more inputs than others. These will be your inputs, and you’ll want to include space for each category in your templates. Once you decide how you’ll use your template, begin the process of building it:īrainstorm the elements you need to map and track in a project. If it’s a project information source, templatize the way your team will attach documents and track processes. For example, if you’re using this as a project schedule, focus on building out ways to assign tasks and delegate work. Is this going to serve as your project schedule, or will this template be your real-time project information source once the work begins? Depending on what you need the chart for, you might include more or less detail. ![]() To create your own Gantt chart template, consider the use case and complexity of your typical projects. ![]() Select your PDF file, then click Edit PDF from the Edit tab to launch.

![]() In other words, it measures the vertical distance between the actual data point and the predicted point on the line, or it measures how far the estimate is from the actual data value. The absolute value of a residual measures the vertical distance between the actual value of y and the estimated value of y. It is not an error in the sense of a mistake. The term y 0 – ŷ 0 = ε 0 is called the error or residual. It is not generally equal to y from data, but it is still important because it can help make predictions for other values. It is the value of y obtained using the regression line. The ŷ is read y hat and is the estimated value of y. Each point of data is of the the form ( x, y), and each point of the line of best fit using least-squares linear regression has the form ( x, ŷ). Rounding to the nearest tenth, the calculator gives the median–median line of y = 6.9 x − 315.5. The calculator shows a slight deviation from the previous manual calculation as a result of rounding. The slope, a, and y-intercept, b, will be provided. You can enter the x and y values into two separate lists choose Stat, Calc, Med-Med and then press Enter. The median–median line may also be found using your graphing calculator. Thus, the equation can be written as y = 6.9 x − 316.3. The line of best fit is represented as y = m x + b. Substituting these sums and the slope into the formula gives b = 476 − 6.9 ( 206.5 ) 3 b = 476 − 6.9 ( 206.5 ) 3, which simplifies to b ≈ − 316.3. The sum of the median x values is 206.5, and the sum of the median y values is 476. The y-intercept may be found using the formula b = Σ y − m Σ x 3 b = Σ y − m Σ x 3, which means the quantity of the sum of the median y values minus the slope times the sum of the median x values divided by three. Substituting the median x and y values from the first and third groups gives m = 174 − 143 71 − 66.5, m = 174 − 143 71 − 66.5, which simplifies to m ≈ 6.9. ![]() The slope can be calculated using the formula m − y 2 − y 1 x 2 − x 1. This allows us to find the slope and y-intercept of the median–median line. When this is completed, we can write the ordered pairs for the median values. Table 12.5 shows the correct ordering of the x values but does not show a reordering of the y values. However, to find the median, we first must rearrange the y values in each group from the least value to the greatest value. The corresponding y values are then recorded. We must remember first to put the x values in ascending order. The first and third groups have the same number of x values. ![]() We first divide our scores into three groups of approximately equal numbers of x values per group. If multiple data points have the same y values, then they are listed in order from least to greatest y (see data values where x = 71). Remember that this is the data from Example 12.6 after the ordered pairs have been listed by ordering x values. Let’s first find the line of best fit for the relationship between the third exam score and the final exam score using the median–median line approach. We can obtain a line of best fit using either the median–median line approach or by calculating the least-squares regression line. If each of you were to fit a line by eye, you would draw different lines. We will plot a regression line that best fits the data. Linear Correlation Coefficient is the measure of strength between any two variables.The third exam score, x, is the independent variable, and the final exam score, y, is the dependent variable. \( \rho_\) 4.What is the Linear Correlation Coefficient? The equation given below summarizes the above concept:.This value is then divided by the product of standard deviations for these variables.The correlation coefficient can be calculated by first determining the covariance of the given variables.How to Calculate Correlation Coefficient? It cannot differentiate between dependent and independent variables. It measures the strength and direction of the linear relationship between the two variables and cannot capture nonlinear relationships between two variables. There are several types of correlation coefficients, Pearson's correlation (r) being the most common among all. The following correlation graphs show the examples of different range of values for a correlation coefficient: This means that any value beyond this range will be the result of an error in correlation measurement.Ī correlation of value -1.0 means a perfect negative correlation, while a correlation of +1.0 means a perfect positive correlation.Ī correlation of 0.0 means no linear relationship between the movement of the two variables. The value of the correlation coefficient ranges from -1.0 to +1.0 The correlation coefficient is used to measure the strength of the relationship between two variables. ![]() What Is Correlation Coefficient?

![]() The reality is that 5 out of 100 males and 1 out of 100 females have my version of colour blindness and we generally lead quite normal lives, in that it’s not so much a complete lack of colour perception rather it’s more just a difficulty in determining various hues.īut what does this mean for the practising teacher? Well, perhaps it’s time to consider running one of these colour blind tests with your students. At this point, they’re understandably confused as the students expected a completely different answer. You could imagine that once students find out that I’m colour blind, invariably they can’t help but want to point out colours around the room in the hope to hear a strange answer … yet most of the time only to be disappointed as I keep naming most colours perfectly! You see, it is a standard misconception of students that all colour-blindness is alike and that we see things in ‘black and white’ (this condition whilst does exist is extremely rare!). It’s a sex-linked condition, in that the photopigment production genes are carried on the X chromosome and males only get one of those whereas females get both, causing males to show the condition more often (only one gene needs to be functional for normal colour vision to result). Basically, the cone-shaped structures within my retina have defective photopigments and as such don’t pick up light frequencies in the same way that the most of the population does. It also means that some blues and purples look similar as does some pinks and greys. This means that greens, reds, yellows, oranges and browns all can all look quite similar to me, especially when it is dim. My specific type of colour blindness is called deuteranomaly, which basically means that my retina at the back of my eye will not pick up much green light and instead is quite sensitive to reds, yellows and oranges. There are several types of colour blindness. ![]() Being a science teacher I couldn’t help myself but use my condition to my advantage, namely delving into the issue with real-life examples and how it actually works.ĭo both sides of the photo seem the same colour? Perhaps this might indicate colour deficiency. As the majority of the population sees the spectrum from red to violet, it is difficult for students to understand how colour perception can be different between people. They were in the middle of a unit covering the 5 senses and as I personally have red-green colour blindness, the kids were very interested trying to understand what I see when exposed to same frequencies of light as themselves. Only recently I was at school running a human body science incursion and the topic of vision & colour blindness was clearly a major interest with the students. The thing is, how often does the inability to perceive colours get picked up in class? Does it really have an impact on education, or is it just an oddity? As I myself have a form of red-green colour blindness, I thought I might dive deeper into this from a personal perspective as well as from a science educators point of view. Often seen as the ‘dot test’, people can get an idea of how well they see colours by running themselves through a series of quick tests in which they need to pick out the numbers and patterns depicted. Many people are aware of the variety of colour blindness tests available that are based on the Ishihara Colour blindness tests plates developed by Dr Shinobu Ishihara in 1917.
