Main article: Maritime mobile service Radio room clock, showing the 500 kHz silence periods (red wedges), the 2182 kHz silence periods (green wedges), and alternating red and white bars around the circumference to aid manual transmission of the 4-second SOLAS signal. CQ like calls (to see who is out there) should not take place until after 4 minutes after the hour. Priority transmissions should begin with the LITZ (Long Interval Tone Zero or Long Time Zero) DTMF signal for at least 5 seconds. A ham in a remote location may be able to relay emergency information through another wilderness ham who has better access to a repeater. The Wilderness protocol (see page 101, August 1995 QST) calls for hams in the wilderness to announce their presence on, and to monitor, the national calling frequencies for five minutes beginning at the top of the hour, every three hours from 7 AM to 7 PM while in the back country. The Wilderness Protocol is now included in both the ARRL ARES Field Resources Manual and the ARES Emergency Resources Manual. The Wilderness Protocol recommends that those stations able to do so should monitor the primary (and secondary, if possible) frequency every three hours starting at 7 AM, local time, for 5 minutes starting at the top of every hour, or even continuously. A single ship, aircraft, spacecraft, or group of them may also maintain radio silence. The term "radio station" may include anything capable of transmitting a radio signal. In telecommunications, radio silence or Emissions Control ( EMCON) is a status in which all fixed or mobile radio stations in an area are asked to stop transmitting for safety or security reasons. Polyhedrons are classified and named according to the number and type of faces. The cross sections of a convex polyhedron are all convex polygons. The intersection of a plane and a polyhedron is called the cross section of the polyhedron. Convex polyhedrons, also known as Euler polyhedrons, can be defined by the equation E = v + f – e = 2, where v is the number of vertices, f is the number of faces, and e is the number of edges. Vertices are connected through the body of the polyhedron by an imaginary line called a diagonal.Ī polyhedron is classified as convex if a diagonal contains only points inside of the polyhedron. The points at which the ends of edges intersect (think of the corner of a cereal box) are the vertices. The line segments along which the faces meet are called the edges. The bounding polygons of a polyhedron are called the faces. In an interesting exception, however, crystals grow in mathematically perfect -and frequently complex - polyhedrons. Most shapes formed in nature are irregular. The pyramids are a type of polyhedron, as are geodesic domes. The cube is seen in everything from dice to clock radios CD cases and sticks of butter are in the shape of polyhedrons called parallelpipeds. Many common objects are in the shape of polyhedrons. ” A polyhedron is a solid whose boundaries consist of planes. The word polyhedron comes from the Greek prefix poly-, which means “many, ” and the root word hedron which refers to “surface. Louis: Webster Division McGraw-Hill Book Company, 1962.Ī polyhedron is a three-dimensional closed surface or solid, bounded by plane figures called polygons. Modern Geometry: Its Structure and Function. The construction of polyhedron models can help make concepts in geometry easier to learn. Because a net is a flat pattern that can then be folded along the edges and taped together to regenerate the polyhedron of origin, a net therefore enables the easy construction of basic polyhedrons out of paper. A net contains all faces of a polyhedron, some of them separated by angular gaps. The resulting map, similar to a dressmaker's pattern, is called a net. NetsĪ polyhedron can be "opened up" along some of its edges until its surface is spread out like a rug. For example, a truncated dodecahedron is made of the pentagon-pentagon-triangle sequence. Each face is a regular polygon, and around every vertex the same polygons appear in the same sequence. Another common group of polyhedrons is the Archimedean solids, in which two or more different types of polygons appear. The tetrahedron consists of four triangular faces, and is represented as. The illustration below depicts the five Platonic solids (from left to right): tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The Platonic solids are within the larger grouping known as regular polyhedrons, in which the polygons of each are regular and congruent (that is, all polygons are identical in size and shape and all edges are identical in length), and are characterized by the same number of polygons meeting at each vertex. One common group is known as the Platonic solids, so-called because its five members appeared in the writings of Greek philosopher Plato. There are many groupings of polyhedrons classified by certain characteristics -too many to discuss here. Using the Euler characteristic and knowing two of the three variables, one can calculate the third variable. The value of v + f − e for a polyhedron is called the Euler characteristic of the polyhedron's surface, named after the Swiss mathematician Leonhard Euler (1707 –1783). For example, the cube has 8 vertices, 6 faces, and 12 edges, which gives 8 + 6 − 12 = 2. The relationship between the number of vertices ( v ), faces ( f ), and edges ( e ) is given by the equation v + f − e = 2. The illustration below indicates these features for a cube, which is a well-known polyhedron comprised of six square faces. A point where three or more edges meet is called a vertex. A straight side that intersects two faces is called an edge. A polygon is considered irregular if its interior angles are not equal or if the lengths of its sides are not equal.Įach of the polygons of a polyhedron is called a face. Some common polygons are the triangle (with three sides), the quadrilateral (with four sides), the pentagon (with five sides), the hexagon (with six sides), the heptagon (with seven sides), and the octagon (with eight sides).Ī regular polygon, like the square, is one that contains equal interior angles and equal side lengths. The number of sides of each polygon is the major feature distinguishing polyhedrons from one another. A square and a triangle are two examples of polygons. Polygons are flat, two-dimensional figures (planes) bounded by straight sides. A polyhedron is a closed, three-dimensional solid bounded entirely by at least four polygons, no two of which are in the same plane. What’s Changed? Festool has made some questionable design choices, such as launching a cordless dust collector vacuum that can only be used with smaller low capacity batteries. The brand is not focused on the broader needs of users involved in construction or the trades.Īdditionally, Festool’s high pricing can make the tools inaccessible to many individual users. Festool made a push in 2020 to consolidate some of their cordless power tools into combo kits aimed at contractors and remodelers.įestool’s cordless platforms are limited, presumably because they are more of a finish and fine work brand. What I Said in 2021: If you want a Festool power tool, and you want it to be cordless, you have some options. Related Tool News: Dewalt 12V Max, Dewalt 20V Max, Dewalt FlexVoltīenefits: Unique tools, such as hybrid corded-cordless sanders, good quality, brand reputation.ĭownsides: Very limited product selection, very high pricing. Even so, FlexVolt still provides a power benefit that most other 18V/20V Max systems struggle to match. Notable Products: Power Detect and FlexVolt Advantage lines bridge the gap between 20V Max and FlexVolt 60V Max platforms. Dewalt’s PowerStack batteries provide numerous benefits over older technologies. What’s Changed? Dewalt has entered the automotive tool market with new ratchets, and recently launched new rivet tools. If I had to choose a “Best Cordless Power Tool Brand Overall” winner, Dewalt would face off against Milwaukee in a battle too close to easily call. Dewalt’s cordless platforms continue to have a lot of strengths, and few weaknesses. Quite simply put, you cannot go wrong with Dewalt cordless power tools. What I Said in 2021: Dewalt continues to have a lot of “firsts.” They’re no longer playing catch-up and are once again pushing boundaries. For instance, you can now choose between 20V Max brushless, 20V Max Power Detect, FlexVolt 60V Max, and 20V Max FlexVolt advantage saws. Dewalt has been continually expanding their 20V Max cordless power tool lineup, as well as their FlexVolt lineup, and they have also been actively expanding their 12V Max Xtreme Subcompact line.ĭownsides: Sorting through some of their core options can be a little confusing. Related Tool News: Bosch 12V Max Tools, Bosch 18V Tools Craftsmanīenefits: Excellent tools, expansive selection, comfortable ergonomics, great reliability. I anticipate that AmpShare will greatly help with this. They have been releasing new tools at a faster pace, and also seem to have abandoned the somewhat silly names given to certain tools, such as “the Freak.”īosch still has holes in their cordless lineup, but they’ve been filling some of the more glaring ones. What’s Changed? Bosch recently launched AmpShare, where their 18V battery will soon power a range of tools from numerous partnered brands. While I was impressed with some of their past releases, there are fewer reasons to buy into either of Bosch’s cordless power tool systems today. Looking at the greater picture, their 12V and 18V platforms aren’t as compelling as competing platforms. What I Said in 2021: Bosch makes some spectacular tools. Benefits: Good performance and reliability.ĭownsides: Historically, Bosch has not kept up with competitors in the USA, and some innovations are released here later than in Europe or not at all. The exhibit’s goal is intended to spark curiosity and excitement, as the glowing steps recreate the effect of walking along a beach at night and witnessing the bioluminescent organisms that illuminate dark ocean waters.

Lesson 2.How can we do this and what can we learn from doing so? First, it is to advance the case for activity theory (AT) as a credible and alternative lens to view and research sports coaching. Lesson 1.CT invites us to “interrogate dichotomies” (Morin, 2007).What paradigm is CT attempting to shift?.Activities are specific, each one answering a definite need of the subject, directed toward an object. In order to combine both perspectives, we developed an Activity Theory. Also taken up are additional lessons afforded by the theory, specifically, overcoming dualities, the need to distinguish a focal system from its environment for the purposes of investigation, and how generalizability can be achieved. The multitheoretical perspective included the three theories of radical constructivism, activity theory, and complexity theory, as represented by Jean Piaget. There is similar complexity in the CHAT concept of object. The complexity of socio-technical interaction is increasingly representing a. These are discussed here as thirty aphorisms. Nevertheless, a metatheory still warrants object theories: in the case of second language development, a theory of language and a theory of learning. A metatheory has wide, transdisciplinary implications. I also relate how I have come to see CT as a metatheory. This is not to say that CT is without antecedents in history, some of which are mentioned in the chapter. The method of analysis by units is used to analyse the larger, complex process on the basis that the larger process is just thousands and thousands of such. Elaboration could be indexed by a number of action characteristics, such as complexity, the expertise of the actor, and the purpose mediating the action. These qualities make the non-reductionist, ecological, dynamic systems view that CT affords appropriate for our post-structural times. The perspective provided by activity theory suggests that the elaboration of plans and anticipations will also influence activity memory. This is not surprising, considering the state of the modern world – its dynamism, interconnectivity, mobile populations, changing climate, pattern of unintentional consequences, space-time compression, and technological innovation. Interest in Complexity Theory (CT) is growing. The the entire point of a dim7th chord is that it has many different interpretations and this can help one reinterpret it different to lead to different harmonic consequences. (e.g., if you are improvising you might want to think of it as sort of Lydian augmented so you can come up with new material that still relates in some way) Ultimately it depends on context and what one is trying to do with it. Maybe the lydian explanation I gave is nonsense because it makes more sense to think of it just as a C#o7 chord over a G# pedal. The point here is that it doesn't matter how you think about it. The G and A# are the maj7th and maj9th and act as dissonances but work because they make sense locally(It's just a Dim7 chord) and make sense globally as just dissonances that resolve to something that works/make sense next(A true G7b9). In the case of C#o7 over the G# bass, it creates a Lydian augmented sound: G# C# E(D#) G Bb(A#). In each case though they are variations of coloration of the V7b9 chord. All these though are essentially a G#7b9 sound as Beethoven peddles the G# to reinforce this. The G# acts as the V7b9 chord for the C#min tonic but the diminished sound is expressed and not the dominant sound due to the arpeggiation of D#o7(a V7b9), then C#o7(a io7 or a #ivo7 etc), then F#o7(V7b9). You just know how to communicate the basic color and then use your intuition(experience) to interpret it and understand it.įor example, in moonlight sonata there is a section of 3 dim7th arpeggios(2 out of the 4 possible) over a G# bass. Once you understand it through experience then you realize it is not something that can be explained using worse because the words are not the thing. Ultimately one just needs to familiarize themselves with how harmony works and how to name chords/colors and then everything else takes care of itself. We get in to the trap because "basic" harmonies are generally not ambiguous(but they can be) and we think all other harmonies sorta have the same simple interpretation. It's not about tying things down and saying it has to be X. Also different people will have different "expectations". Of course it might be clear it is part of something else, e.g., G7 Ab7b9 G7 if that is more natural. E.g., if you play Cmaj7 Cdim7 Cmaj7 and Cmaj7 is clearly the quality for the C chord then that Cdim7 is functioning as an alteration of Cmaj7 and it will sound different than if you did G7 Cdim7 G7 in which case the Cdim7 will be functioning in terms of G7 giving a sort of G7 Lydian augmented if the context is appropriate. It is harder to do but if you've established Cmaj7 as the quality for the C chord and then play Cdim7 you are essentially combining Cmaj7 and Cdim7 and it will color that Cdim7 as a Cmaj7 sound. You can make a diminished chord be a minor chord, a major 7th chord, or whatever. You simply want to learn how it works by usage rather than try to peg it to some ideal or specific thing that it must be. It is not about it being a specific thing. You want to always think of a dim7th as also being 4 V7b9 along with variations such as #ivo7, #vio7, io7, etc. The issue is that a diminished 7th chord has 4 V7b9 chords and not every one will work in the global context and they do have different sounds in some cases. Every diminished 7th can substitute for a V7b9 and vice versa. :)Ī diminished 7th chord is a V7b9 chord without the root. It would be a stretch to declare all of them V7-ish, unless one had a very limited list of allowed labels. Further, as in George Shearings "locked hands" voicings, diminished chords are simply not-quite-in-the-scale passing chords between inversions of something like I69 or other pentatonic-ish chords. Not going to the tonic or even secondary tonics, etc. Not always, though! Already in Brahms, and in jazz-standard-type stuff, the voicings often are stretched-out diminished chords, whose function is as much voice-leading as V7. But, still, I'd agree that its sound/function often is V7-ish. If the question is about whether or not various specific practice traditions would consider it so. I recall, as a kid, thinking that the diminished chords in classical music "really needed to be filled out to V7 chords". Interestingly/ambiguously, depending on the inversion/voicing, it can pretend to be an incomplete V7 in 4 different (major) keys. Certainly in some circumstances it functions as a V7 chord. |
