Sound Analysis Pro — Animal Behavior

SA+ eliminates much of the efforts involved in maintaining long-term vocal learning experiments, allowing automated acquisition and analysis of large amounts of sound data, scheduled training and on-line monitoring of behavior of several animals simultaneously. SAP2011 is an open code freeware with several options and extensions that can be implemented. Feature summary of SAP2011: SAP2011 can be installed in any Windows computer (XP to Windows 7). 1. 2. 3. 4. 5. 6. 7. 8.

About Sound Analysis Pro Sound Analysis Pro2011 is an integrated system for studying animal vocalization. SAP2011 is an extension of Sound Analysis 3, although little remains from previous versions. Ofer Tchernichovski. Game of Thrones. Magic Hexagon for Trig Identities.

Magic Hexagon for Trig Identities

Here is how: Building It: The Quotient Identities OK, we have now built our hexagon, what do we get out of it? Well, we can now follow "around the clock" (either direction) to get all the "Quotient Identities": Product Identities The hexagon also shows that a function between any two functions is equal to them multiplied together (if they are opposite each other, then the "1" is between them): Some more examples: sin(x)csc(x) = 1 tan(x)csc(x) = sec(x) sin(x)sec(x) = tan(x) But Wait, There is More!

You can also get the "Reciprocal Identities", by going "through the 1" Here is the full set: sin(x) = 1 / csc(x) cos(x) = 1 / sec(x) cot(x) = 1 / tan(x) csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) tan(x) = 1 / cot(x) Bonus! AND we also get these: Double Bonus: The Pythagorean Identities The Unit Circle shows us that sin2 x + cos2 x = 1 You can also travel counterclockwise around a triangle, for example: Spike sorting - Scholarpedia. Figure 1: Extracellular recordings are usually done by inserting microwires in the brain.

Spike sorting - Scholarpedia

The signal from the microwire is amplified and band-pass filtered and the firing of the nearby neurons appears as spikes on top of background activity. Spikes are detected using an amplitude threshold and then sorted according to their shapes. For neurons close to the electrode tip -about 50 to 100 microns (Gerstein and Clark, 1964; Buzsaki, 2004)- the signal-to-noise ratio is good enough to distinguish the activity of each single unit (inner circle).

There are also Java applets with sound as well as interactive Java applets. World Dance New York. Dancing Like There's No Tomorrow: Nancy E. Hussey: 9781449045975: Books. Do Try This At Home. Scientific experiments do not need to happen in fancy laboratories.

Do Try This At Home

Exploring science can happen at home using inexpensive supplies. Oobleck Oobleck is a non-Newtonian fluid that behaves unlike other fluids. Flowing freely, it behaves as a regular liquid, but when a force is applied, it is more like a solid. If you pick oobleck up with your hands, it will easily flow through your fingers. For this experiment, you will need: 1 part water 2 parts cornstarch Drops of food coloring (there are a few options with this) Combine ingredients and stir.

Oobleck is nontoxic, but does get messy. Precipitation in a Jar: Exploring precipitation at home is quite easy. 200 ml (1 cup) Hot, but not boiling, water Tall glass jar Glass plate Ice cubes Pour the hot water into the clear glass jar and immediately cover with the plate. DNA Extraction DNA can be extracted and examined quite easily. To begin, you will need to choose the source of DNA. Add the plant material, salt, and water to the blender.
