The child would need to work out that the two angles shown equal 70º. They may be given a diagram like this (not drawn to scale): They are taught that the internal (inside) angles of a triangle always total 180º. (If we didn't divide by 2 we'd be calculating the area of a rectangle, represented below by the total green area.)Ĭhildren in Year 6 also move onto finding unknown angles in triangles. We multiply these to make 24cm and then divide this by 2 to make the area which is 12cm². This means that you multiply the measurement of the base by the height, and then divide this answer by 2.įor example, this dark green triangle has a base of 6cm and a height of 4cm. There is a basic formula for this, which is: ![]() In Year 6, children are taught how to calculate the area of a triangle.

The following email was sent with an optimized and carefully crafted signature, with the CTA built-in. Worse than that, though, is the fact that the reader devotes almost no attention to the call-to-action underneath the signature.

![]() What can you add that doesn't exist in other systems? Tilt already has mechanisms for logging and displaying data during fermentation.If you use an external sensor, what kind and how does it fit into the fermenter hardware? Interfacing with a Tilt would be one idea. ESP8266 and such have built-in temperature sensors, but most are not very accurate. Think about how you will get your data, not just how to display it.If you log to a Google sheet with a graph, then embedding the graph in a multi-platform display is easy. Use common data formats, such as CSV or Excel. Use what is already available where you can. Some overall thoughts (based upon my own experience with a home-built system) 3 meads, 2 grape juice wines, 2 more ciders and a cran-raspberry juice thing. Currently I have 8 one gallon carboys going with 4 probably ready to rack tomorrow. PPS, I had my first cider finish last weekend and it was great. I am doing this partly as a class final project and as a demonstration to prospective employers. PS, I have not looked much at what software may already exist. What would the brewing community like to see in something like this. Drop down boxes for brew type, date stamp for each entry, large note section. What I am looking for is input as to what should be included in the software/hardware. ![]() The plan so far is a Java GUI and one of my final classes is Android development so an Android app with wifi enabled ESP8266 for temperature logging of each brew. I was going to start on some software/hardware to track and monitor/datalog brewing with the plan of making it all open/free for anyone to use. I do Java programming for work and embedded systems testing along with some programming of embedded systems. I am new to brewing and am not quite a software developer, in my 40's and 3 classes away from BS Computer Engineering. A sound with a loudness of four sones is one that listeners perceive to be four times as loud as the reference sound. One sone is arbitrarily set equal to the loudness of a 1,000- hertz tone at a sound level of 40 decibels above the standard reference level (i.e., the minimum audible threshold). Consequently, the sone scale of loudness is based on data obtained from subjects who were asked to judge the loudness of pure tones and noise. Loudness is a subjective characteristic of a sound (as opposed to the sound-pressure level in decibels, which is objective and directly measurable). The Encyclopedia Britannica describes sone as follows: ![]() Raise the same 20 decibel whisper to 500 Hertz and it becomes audible. Meaning our perception of sound level is related to the frequency of the sound wave.įor instance, a 20 decibel whisper delivered at 100 Hertz (frequency measurement) cannot be heard by the human ear. Most people hear high frequency sound waves better than lower frequencies. The human test subjects used to develop the sones rating system were asked to describe how loud a sound felt.Ī sone rating for sounds may be more useful because humans sense higher and lower sound wave frequencies differently. It is a system to tell how loud a sound feels to humans. Sones are not a physical measurement like decibels. The sones rating system is a way to measure or express perceived loudness. For every 3 decibel increase or decrease, you are adding or dropping 50% of the sound pressure levels your ears are exposed to. A simplified explanation is the 3 Decibel Rule. In some ways sone noise levels are easier to understand then decibel levels.ĭecibel levels use a logarithmic scale like the Richter earthquake scale. 2 sones are twice as loud as 1 sone and 4 sones are twice as loud as 2 sones. This means that doubling the number of sones doubles the noise level. If you know what a sone represents in the real world (See chart below.), you will be better able to know what the machine will sound like. But some electrical or mechanical equipment like range hoods and bathroom fans give sound value in sones. ![]() Most sound levels for equipment such as lawn mowers or compressors are given in decibels. Not very helpful? Please read on for real information that you can use when confronted with noise levels expressed in sones. Phon: a unit of the perceived loudness of sounds. Sone: a unit of subjective loudness, equal to 40 phons. Here is the Concise Oxford Dictionary definition. But when a measurement of noise level is expressed in sones, we might be a little confused. Most people have at least a rough idea of what a decibel is. ![]() ![]() Use of the Mean Squared Error(MSE) as the cost on a dataset that has many large outliers, can result in a model that fits the outliers more than the true data due to the higher importance assigned by MSE to large errors. Linear regression models are often fitted using the least squares approach, but they may also be fitted in other ways, such as by minimizing the " lack of fit" in some other norm (as with least absolute deviations regression), or by minimizing a penalized version of the least squares cost function as in ridge regression ( L 2-norm penalty) and lasso ( L 1-norm penalty). If the goal is to explain variation in the response variable that can be attributed to variation in the explanatory variables, linear regression analysis can be applied to quantify the strength of the relationship between the response and the explanatory variables, and in particular to determine whether some explanatory variables may have no linear relationship with the response at all, or to identify which subsets of explanatory variables may contain redundant information about the response. ![]() After developing such a model, if additional values of the explanatory variables are collected without an accompanying response value, the fitted model can be used to make a prediction of the response. If the goal is error reduction in prediction or forecasting, linear regression can be used to fit a predictive model to an observed data set of values of the response and explanatory variables.Most applications fall into one of the following two broad categories: ![]() Linear regression has many practical uses. This is because models which depend linearly on their unknown parameters are easier to fit than models which are non-linearly related to their parameters and because the statistical properties of the resulting estimators are easier to determine. Linear regression was the first type of regression analysis to be studied rigorously, and to be used extensively in practical applications. Like all forms of regression analysis, linear regression focuses on the conditional probability distribution of the response given the values of the predictors, rather than on the joint probability distribution of all of these variables, which is the domain of multivariate analysis. Most commonly, the conditional mean of the response given the values of the explanatory variables (or predictors) is assumed to be an affine function of those values less commonly, the conditional median or some other quantile is used. In linear regression, the relationships are modeled using linear predictor functions whose unknown model parameters are estimated from the data. If the explanatory variables are measured with error then errors-in-variables models are required, also known as measurement error models. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable. The case of one explanatory variable is called simple linear regression for more than one, the process is called multiple linear regression. In statistics, linear regression is a statistical model which estimates the linear relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). Statistical modeling method Part of a series on Even with a string, the square edge makes it necessary for angled tick marks to be the source of the reading a round compass rose trying to be read off a square piece of plastic! If your azimuth lies in between the tick marks.Another field expedient is to take the straight edge of a sheet of paper, lay it along the two points to be measured and then lay the protractor on top in order to get a reading. The RM protractor as can be seen in the picture here comes with an elastic string that is tied around the outside edge of the protractor for azimuth measuring. Two knots secures the string to the protractor center but creates a bulge so the protractor will not lay flat on your military topographic map. It takes a 1:50,000 scale map distance of 1,800 meters just to reach the protractor's square edge to get a reading.Īnother self-help technique is to poke a hole in the center and place a knotted string in the center to overlap extend over your map lines for a reading, but this leaves a knot in the center, obscuring the center placement of the original point to be measured from and the string can fall out at the worst possible time. You lose the mills scale for artillery calls for fire and still have to draw extended lines on your map, cluttering and obscuring important details. Often hand trimming of the mils edge results in a sloppy, uneven edge cutting off degree marks. When measuring a grid angle from point A to point B on a map with the Army protractor, you are often forced to draw and extended line so you can reach the square's edge for a measurement! An improvement somewhat is to trim the mils scale off, but not a significant enough improvement. The RM protractor is round with degrees and mils scales on the outside edge. Army protractor (GTA 5-2-12) is a square shaped piece of clear plastic with mils scale and degrees on the outside edge of the square. ![]() Army SNCO, Rudy Madayag and offered in military clothing sales stores (MCSS) is far superior, easier to use and more accurate. The round and improved square map protractors produced by retired U.S. ![]() The current square issue map protractor ( GTA 5-2-12) is cumbersome to use, resulting in added time in planning, and inherently inaccurate resulting in map errors that can cause units to get lost and rounds to fall on friendly forces. |
