The idea behind memory mapping is that a device will be connected to the system's address bus and uses a circuit called an address decoder to watch for reads or writes to its assigned addresses responds accordingly. Memory-mapped I/O uses the same mechanism as memory to communicate with the processor, but not the system's RAM. Not exactly, which is why the diagram in the question doesn't quite depict memory-mapped I/O. Thus, from this discussion, we can conclude that I/O-mapped I/O offers easy decoding but memory-mapped I/O offers difficult decoding and the reason for the same is that the latter has more number of address lines.So basically you access the device controller registers through memory. During the memory read and memory write cycle, the IO/M’ signal is kept low while during IO read and IO write cycle, the IO/M’ signal is asserted high.The memory mapping of the I/O devices facilitates interfacing of more number of I/O ports but the I/O mapping of I/O devices facilitates interfacing of fewer IO ports nearly 256.While the I/O mapped ports, allow the transfer of data to take place between the I/O devices and the processor. The memory-mapped ports allow data to get transferred between any register and the ports.However, the same case does not apply to isolated I/O as in IO-mapped IO, the devices are accessible through I/O read and I/O write cycle. In the memory-mapped I/O approach, the I/O devices are accessible through memory read and memory write cycles.As against, there are separate instructions, IN and OUT are used for data transfer between the I/O device and the processor in I/O-mapped I/O. In memory-mapped I/O, the I/O ports or peripherals are considered as memory locations and due to this reason, the memory-specific instructions can be used for data transfer between the I/O device and the processor.Hence, suits the systems that require large memory capacity. Whereas, when I/O-mapped I/O is done then the overall memory space can address the memory. Thus, it is suitable for systems where less memory requirement exists. When memory-mapped I/O is done then the whole available memory space cannot be used for addressing the memory as the I/O devices are also addressed within the same memory.While in I/O-mapped I/O, separate address spaces are used for memory and I/O device. The key factor of differentiation between memory-mapped I/O and Isolated I/O is that in memory-mapped I/O, the same address space is used for both memory and I/O device. Key Differences Between Memory-mapped I/O and I/O-mapped I/O The required chip select signals in this case are generated by an individual decoding unit. Here the operation takes place in a way that, if the data over which operation is to be performed is to be collected from the I/O devices then address is placed on the address line and I/O read and I/O write control lines will get activated so that data transfer can be performed between the processor and I/O.įor the transfer of data between the processor and I/O devices, only IN and OUT instructions are used in the isolated mapping. In this approach, there is a common bus for I/O devices and memory however, individual read and write control lines are used for I/O. Thus, different read and write instructions are used for I/O and memory. It is also known as Isolated I/O mapping and the reason for the same is that here the address space of memory and I/O are separated from each other. The same is the case with the memory write operation. In such a case, the processor is not concerned whether the responding data is coming from a memory device or an I/O device. So, whenever, an address is generated on the address bus then resultantly control signal is generated for memory read. In this case, the processor considers the I/O ports as memory locations for the purpose of reading and writing. This reduces the addressing capability of the memory. Thus, I/O is considered as memory and the same address space is used by both memory and I/O devices. Here each bus is common thus the same set of instructions is used for memory and I/O devices. In memory mapping of I/O devices, the I/O ports are assigned 16-bit address within the memory. In small systems where memory requirement is less. Special control signals are used for I/O devices.ĭuring memory read or memory write operations, IO/M’ is kept low.ĭuring I/O read and I/O write operation, IO/M’ is kept high. No separate control signal is needed for I/O devices. Content: Memory-mapped I/O Vs I/O-mapped I/O While in case I/O mapped I/O only IN and OUT instructions are accessed. In memory mapped I/O the memory-specific instructions are used by the I/O device.

Kenny Rogers’ Through the Years is a song about looking back at the past you’ve shared with someone. Lyrics about remembering the past: Standin’ on your mama’s porchīryan Adams’ song was about summertime love and eventual heartbreak, so let’s visit the other side of the fence. That’ pretty obvious because this is a song about summertime and making love, and back in 1969 Adams was just 9 years old! ".Contrary to what people say, Summer of 69 isn’t really about Bryan Adams’ summer back in 1969. So I named it ‘Good Riddance’ just to express my anger.” 3. “In the song, I tried to be level-headed about her leaving, even though I was completely pissed off. “It’s about an ex-girlfriend who had moved to Ecuador,” the singer told Guitar World, according to Louder Sound. It was something unpredictable, but in the end, “Good Riddance” was actually a song about lead singer Billie Joe Armstrong’s ex. The rock band went from being alternative to the singers of everyone's graduation song for a decade. "Good Riddance (Time Of Your Life)" By Green DayĪnother turning point, a fork stuck in the road Time grabs you by the wrist, directs you where to go So make the best of this test and don't ask why It's not a question, but a lesson learned in time It's something unpredictable but in the end is right I hope you had the time of your lifeįor most of the ‘90s, Green Day set the standard for alternative music with the songs “Basket Case,” “When I Come Around,” and “Longview” from their hit album Dookie. It just shows that the classic album and song are still here to remind you of how awesome it always has been, even decades later. And now in 2019, Morissette’s 1995 Jagged Little Pill album, which contains “You Oughta Know,” is headed to Broadway as a musical opening later this year. You moved on, of course, but not after belting this tune in your car or at an impromptu karaoke event - just like in the movie Booksmart. And it was even more than OK to sing about it loud and proud in a song that was considered pretty edgy for the ‘90s. The 1995 song that taught you that it was OK to be upset and hurt after a breakup. The iconic breakup song of a generation that you know deep in your soul - and if you don’t seriously oughta know. 'Cause the love that you gave that we made Wasn't able to make it enough for you To be open wide, no And every time you speak her name Does she know how you told me You'd hold me until you died 'Til you died, but you're still alive And I'm here, to remind you Of the mess you left when you went away It's not fair, to deny me Of the cross I bear that you gave to me You, you, you oughta know Check out some unforgettable song lyrics to some of the most memorable '90s songs below. Such an iconic decade shouldn't - and probably won't - be forgotten anytime soon.Īnd neither will the words to certain songs. You can also relive the '90s and see singers like Britney Spears, Mariah Carey, Jennifer Lopez, and Celine Dion in their Las Vegas performance residencies, reviving their best of the decade (along with their new music) on stage in Sin City. Sure, there were definitely some one hit wonders by artists who made a splash and were never heard from again, but some artists have fame that lasted all the way into the 2010s. From grunge and Ska to hip-hop and rap, '90s music had some pretty unforgettable tunes. With that said, there are so many '90s songs whose lyrics you'll never forget, either because they are so darn catch or they've haunted you years later. It doesn't matter what age you are - it's hard to forget the soundtrack to your own childhood. The '90s might be long one, but there are still so many things about the decade that resonate: Lisa Frank designs, all the TV shows that are getting reboots, and so much now-classic music. (1989), "Displacement of Components and Solder during Reflow Soldering", Soldering & Surface Mount Technology, Vol. With the increase of assembly density and SMT, nitrogen filled reflow welding processes and equipment were created to increase the quality and yield of. The first step is to assemble the parts to be joined, including the placement of sufficient solder. After the oven stage, the circuit board undergoes a cooling stage. Reflow soldering consists of two basic processing steps. This will activate the flux in the solder paste in order to remove the oxides on the metal soldering surfaces. Soak: Once the board reaches the first designated temperature, it will remain here for a predetermined period. This causes the solder paste to melt (reflow). The solder reflow process generally follows this pattern: Preheat: This brings the board up to its first designated temperature. From this, important conclusions for vapour phase soldering, infra‐red soldering and hot‐belt soldering may be drawn. During the reflow soldering process, the PCB passes through an oven. The driving forces of the displacements can be explained in terms of forces and pressure caused by the surface tension of the molten solder, whereas the observed influences of the heating method are the result of the direction from which the heat is transported to the solder paste to be melted. Experiments show that all these effects depend on the heating method, vapour phase soldering often being the most prone. Designing and manufacturing state-of-the-art reflow systems for electronics manufacturers worldwide. Moreover, isolated small solder balls are often found on the board surface after melting of the paste. On the other hand, the molten solder may move to places other than those intended, e.g., into metallised holes (PTH) connected to the solder lands, or upwards along component leads away from the joint area this effect is called solder wicking. Reflow soldering is a process in which a solder paste is used to temporarily attach one or thousands of tiny electrical components to their contact pads. Components may move horizontally along the surface of the board (this is called swimming or floating), or may move vertically and stand on their ends (this is called drawbridging or Manhattan effect). This process, however, may be accompanied by various unwanted movements of components and solder. Reflow soldering is also called reflow soldering, which relies on the continuous reflow of the heat in the furnace, so that the solder paste is dissolved into tin liquid to solder the smt chip components and the circuit board. During reflow soldering the applied solder paste is melted and the components, previously placed on the solder paste, move into their final position. Reflow soldering is an automated soldering process in the SMT production process of electronic products. As we continue with testing, we’ll expand the size of these tests, add.

Step 4: Add the axis titles, increase the size of the bubble and Change the chart title as we have discussed in the above example. Step 3: This will create the scatter diagram. The following scatterplot examples illustrate these concepts. Step 2: Go to Insert > Chart > Scatter Chart > Click on the first chart. When you look at a scatterplot, you want to notice the overall pattern and any deviations from the pattern. Consider a scatter plot where all the points fall on a horizontal line providing a “perfect fit.” The horizontal line would in fact show no relationship. For a linear relationship there is an exception. You can determine the strength of the relationship by looking at the scatter plot and seeing how close the points are to a line, a power function, an exponential function, or to some other type of function. High values of one variable occurring with low values of the other variable.Scatter plots are important in statistics because they can show the extent of correlation, if any, between the values of observed quantities or phenomena (called variables). Scatter plots are used for data with two quantitative variables or data. A scatter plot is a set of points plotted on a horizontal and vertical axes. A Scatter Plot is also known as an XY Plot since the variables are plotted. A scatter plot is a graph that displays all of the data points for a set of data. High values of one variable occurring with high values of the other variable or low values of one variable occurring with low values of the other variable. A Scatter Plot is a chart that shows the relationship between two variables (if any).A scatterplot can also be called a scattergram or a scatter diagram. Plot the relationship between the Systolic and Diastolic variables by passing tbl as the first argument to the scatter function followed by the variable names. For example, read patients.xls as a table tbl. A clear direction happens when there is either: A scatterplot displays a relationship between two sets of data. A convenient way to plot data from a table is to pass the table to the scatter function and specify the variables you want to plot. She records the following data: X (hours practicing jump shot)Ĭonstruct a scatter plot and state if what Amelia thinks appears to be true.Ī scatter plot shows the direction of a relationship between the variables. She notices that the number of points she scores in a game goes up in response to the number of hours she practices her jump shot each week. She wants to improve to play at the college level. Its ability to show nonlinear relationships between variables is widely used in. Amelia plays basketball for her high school. A scatter plot is a two-dimensional graphical representation of a set of data. This is not very hard to understand if you think about the logarithmic curve of the way partials are laid out. Basically, the lower a note is registrally, the more likely you are to perceive it as important. There is one more factor, and this has to do with the physics of sound. So to summarize all of this, when you hear a 1-5 relationship in music, it reinforces the 1 as being strong and gives it more tonal gravity. Even in music that rejects tonality, this relationship is abundant, because it is so fundamental to the way we hear and perceive music, it is nearly impossible to avoid. But this is the beginning kernel of explaining why 5 leads to 1 in tonal music. So for all practical purposes, the 5th (which is the 3rd partial, don't want to cause confusion) is the only partial worth worrying about. You can theoretically do this with other partials, not just the 5th, but as the partial number goes up, the strength of that partial goes down drastically. The G is generated from the C, therefore reinforces it as being a strong note. Is it the root of a triad? The 7th of a dim7 chord? A pitch in some ordering of a 12 tone row? However if we play a C-G dyad, it is clear that C is the important note, because we are giving it some context. So for instance, if you play the note C on a piano, it is a little ambiguous what the function of the note is. The fifth is generated through playing the root, and provides clarity of context. So every time you hear a pitch, there is an inherent relationship, of a weaker 5th and a stronger root. The most prominent harmonic of any pitch other than the octave (which would be the same pitch class) is the fifth. Duration is a bit more tricky, but the shortest most concise explanation I can give, is that the longer a note is held and/or the more often it is repeated, the stronger we feel it as being an important note. The things that contribute to mass in a tonal sense are intensity (or volume) and duration. The larger the "mass" of a pitch, the more we feel its gravity. Think of tonal gravity as being analogous to real gravity. There are a couple of reasons why we feel it. So obviously this can get a bit confusing as to why we feel the tonal gravity of certain notes and not others. Do this process again and it becomes mixolydian, then dorian, then aeolean, then phygian, and finally locrian. For ease of explanation, let's take a Lydian mode with all white notes (the most common one anyway): Move the tonic note up a fifth, and if you use the same collection of notes, it becomes ionian mode, or the diatonic scale. Lydian is just the one where the first note in the collection is the tonic note of the scale. Well first of all, Lydian mode is not the only mode based on stacked 5ths. Beginning in Egypt, it follows The Holy Family back to Nazareth, and (like the Gospels) has its climax in Jerusalem. It takes place in Christ’s “hidden” childhood, when Jesus was seven. The filmmakers, perhaps not wanting to prejudice viewer’s minds based on Rice’ less-than-religious prior writings, don’t mention this in trailers, nor the opening credits. The story is based on Anne Rice’ 2005 Novel Christ the Lord: Out of Egypt. A few episodes are similar to childhood stories of Jesus as shown in apocryphal books, but they do not portray anything contradictory to the Christ of the Gospels. Much like the movie Risen which hit theaters last month, The Young Messiah finds a clever way to spread the good news: through fiction that tells a separate story from the Gospels without losing the truth in them. That is an important to take note of. However, such editing is often necessary when taking a story told in several paragraphs in the Bible, and turning it into a feature-length movie (see: Noah). Harder still: doing so when audience members could be offended if the story leaves out or adds details. It’s difficult to generate viewers from texts people have studied for thousands of years. One obstacle studios face is that the stories are already known. Many lament the lack of major motion pictures depicting Bible-based stories. Director Cyrus Nowrasteh achieves this and more. If The Young Messiah (opening Friday, March 11) accomplished nothing other than offering a way to spread biblical values via Hollywood, it would succeed for that alone. Secure Shell (SSH) - used for secure logins, file transfers ( scp, sftp) and port forwarding On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. They are used by system processes that provide widely used types of network services. The port numbers in the range from 0 to 1023 are the well-known ports. Multiple applications are known to use this port. Port is not registered with IANA for the application Port is registered with IANA for the application However, many unofficial uses of both well-known and registered port numbers occur in practice. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses. SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. TCP and UDP port numbers are also used for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). This is why some even numbers in the well-known port number range are unassigned. As Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) were adopted, only one port was needed. Originally, these port numbers were used by the Network Control Program (NCP) and two ports were needed as transmission was done at half duplex. This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suitefor the establishment of host-to-host communications. Step 2: Choose, mix-and-match base object (or start from scratch) Start a new file with an artboard that is 24×24 pixels, RGB color mode, Raster Effects at 300dpi (only affects on-screen dpi), and set “Align New Objects to Pixel Grid” to off (this can be changed later per individual objects).This simple tutorial explains how to generate PNG icon images from Adobe Illustrator, for a script that moves a face of a solid Rhino object while maintaining its face orientation and the existing neighbor edge orientations. RhinoVAULT is a good example where the general guidelines outlined above are (notably the pixel alignment, contrast of color, and edge offset) incorporated well to generate clear, easy to read icons ( from version 1.3.0.1). Use outlines for areas next to the transparent background.Avoid using texts in icons (this clashes with localization).Avoid near-vertical and near-horizontal lines.Try to use the same view projection as the standard Box function button icon.Try not to use the pixels along the edges of the icon (this leaves an active icon size of 22×22 pixels.).White (or other bright) lines should be at least 2 pixels thick.All lines in icons should be a whole number of pixels thick (the default set only contains 1 and 2 pixel lines).Use default Rhino icons in vector format, or raster images as the base to stay somewhat consistent with Rhino’s visual conventions.In Rhino, default button size is “medium”, which is 24×24 pixels (“small” = 16×16 pixels, “large” = 32×32 pixels) → create icons based on 24×24 pixel grid.For clean anti-aliasing, align shapes to the pixel grid whenever possible.Use full alpha-channeled PNG format for all images (so four channels in total: RGBA, not just RGB – automatically done when exporting from Illustrator) the alpha channel controls the level of transparency per pixel, and therefore creates a smooth gradient from fully-opaque to fully-transparent.The vector drawing can be exported as a PNG image and imported “to fit” from Rhino. Using an external vector drawing software – This option is ideal for creating icons from scratch using vector drawing software like Illustrator.Using an external pixel editing software – This option is the “Photoshop” approach, where the icon is created as an image by modifying, adding layers of anti-aliased images, incorporating filters, etc., then saving it as a PNG image with all the layers flattened while keeping the alpha channel. It could be used for minor refinements and tweaks, but is not ideal for creating new icons from scratch. Using built-in Rhino pixel editor – This option does not require any extra software, but the built in pixel editor is a more dumbed-down version of MS Paint with extremely limited drawing functions.There are three ways to change/create custom button icons:.General tips and info on Rhino toolbar button icons Raster image of Grasshopper component icons (via David Rutten from here).Microsoft Developer Network : general information and tips for creating Windows icons (for Windows XP, but still valid tips).McNeel Wiki : thorough explanation on Rhino toolbar button icons.Rhino help : general information on Rhino toolbar styles, sizes and properties.Also included in the post is a short tutorial on how to create an icon from Adobe Illustrator. This post highlights a few good web sources that provide general information and tips for customizing toolbar button icons in Rhino. After writing hundreds of lines of a code that executes a sophisticated operation in Rhino through a single click of a button, it would be nice to have a cool icon to go with it. |
