Block and load 2

CancelProduct actions will be executed next (in that order).From the second iteration onwards only the SearchProduct, OrderProduct and CancelProduct actions will be executed.And in the last iteration, after the CancelProduct action is executed, the Logout and vuser_end actions (in that order) are executed and the script execution stops.Also, we can define two ways of running the Run block (click on the Run block and these options will be enabled on the right)–Sequential and Random.When we set ‘Sequential’, all the actions in the Run block run sequentially (in the order they appear).When we set ‘Random’, we are prompted to enter the percentage weights for each of the actions in the Run block and accordingly only one of these actions will get executed in each iteration.Also, we can define Block (click on Insert Block button) to group related actions. For Example, we can put SearchProduct and OrderProduct actions under a block.2) General->Pacing:Pacing is the time for which the Vuser waits between iterations. It is used to control the number of iterations in a specified time thereby controlling the load on the application. There are three pacing options as shown below.The first option is not used in a load test, it is used for verifying data or for a low load test. Option 2 or 3 can be used to control the load in a load test.3) General->Log:The level of logging can be set here. As logging creates additional overhead on the Load Generators, one should be wise (log only what is required)

Equations (4) and (5), a transfer function with xema as the output and TL and Fema as inputs can be obtained as follows: x ema = η ema k ema T L R − F ema s ( s m ema + B fr ) (6) The model is not specific to the roller-screw type, but is instead general. Equations (5) and (6) are written in the case of an opposite load, and for simplification the case of an aiding load is not considered, although the EMA works in both cases.The open-loop system model block diagram of the planetary-roller screw pair is shown in Figure 3. 3.3. Force SensorSince the force sensor has very small inertia and operates within the range of elastic deformation, the force analysis equation of the force sensor can be obtained as follows: F ema = K s ( x ema − x fs ) (7) Thus, the open-loop system model block diagram of the force sensor is shown in Figure 4. 3.4. Load Connection PointIn order to make the model more perfect, the inertial load is selected in the mathematical model; the mass of the inertial load is 0.001 kg, which is equivalent to no load.Considering the connection stiffness between the LEMA and the load connection point, the force analysis equation at the load connection point can be obtained as follows: F ema = m el x ¨ ema + S t ( x ema − x a ) (8) Thus, the open-loop system model block diagram at the load connection point is shown in Figure 5. 4. Anti-Disturbance Control Strategy for the Force Servo System 4.1. Establishment of an Open-Loop Model of the Force Servo SystemBased on the model block diagrams of each core component, an open-loop model block diagram of the force servo system with the input command u and the external position disturbance xa as inputs and Fema as the output can be obtained, as depicted in Figure 6. Its open-loop transfer function is expressed as follows: F ema = R k ema η ema K i K v C T u − s F ab ( F ema K s + F ema + S t x a s 2 m el + S t ) s L m + R m + K i K f (9) where Fab can be obtained as follows: F ab = { R k

Modified on: Thu, 1 Nov, 2018 at 7:40 PM This guide will show you how to load a multi-timbral instrument like Equator into Cubase.Short answerCreate an instrument track receiving on all channels, and load a multi-timbral plugin such as Equator. Edit the polyphonic expression data (Glide, Press, Slide) using Note Expression.Detailed answerThe Seaboard Block and Lightpad Block use multiple channels of MIDI to achieve polyphonic dimensions of touch. Cubase is very compatible with BLOCKS because it accommodates multiple MIDI channels on a single track which can host a multi-timbral plug-in like Equator.Step 1: ROLI Dashboard SettingsConnect your Blocks and launch ROLI Dashboard. If you're using a Lightpad Block, load the "Note Grid" app and then click the "Edit" button.Ensure that the MIDI Settings in ROLI Dashboard are set as shown below.We have selected:MIDI Mode: MPEMPE Zone: LowerNo. MIDI Channels: 15Pitch bend range: 48 semitonesStep 2: Create an Instrument TrackOpen your Cubase project.Project ➝ Add Track ➝ InstrumentSelect a multi-timbral plugin like Equator.Step 3: Select all MIDI channelsIn the inspector, select the Seaboard or Lightpad Block as the MIDI input, and set the channel to Any. (In this example we’re using a Seaboard Block and the Equator plugin.)Step 4: Equator’s MIDI/MPE SettingsBy default, Equator's MIDI/ MPE Settings will already match those that we select for ROLI Dashboard in step one. But since a mismatch of settings in ROLI Dashboard and Equator can cause silent notes or incorrect pitch bends, it's worth double-checking them now.Open the Equator plugin from your instrument track in Cubase.Click on menu (☰) in the top right and select MIDI/MPE Settings.Ensure that Equator’s MIDI Settings match the ones we set in ROLI Dashboard in Step 1 (by default they should already be correct). Now that Equator is listening for MIDI on the same channels that the Seaboard is

Let's pretend for a moment you are as crazy as myself about computing and, specially, about classic computers like the PDP-11. Let's say your crazyness gets to the point you start to consider seriously writing your own operating system for the PDP-11. Or, at least, doing the first steps to write something similat to an operating system. Sounds scary, doesn't it? No way! It sounds fun!Still reading? Fine, because we are going to do those very first steps towards this goal. And the very first step to build an operating system is to have the hability to write, debug and run standalone software. That is, to run programs in a PDP-11 without any operating system loaded.To do that, we can use two different approaches:We can use a running PDP11 system with an existen operating system to write and assemble the software, moving it to our "empty" system.We can use a cross-assembler and cross-compiler to write the software under another operating system, and feed it to our PDP11.At this point, it is important to remember we are talking about a simulated PDP-11. At least in my case, I don't have access to a real machine. Then, it makes sense to use the host operating environment to write and compile the software we will run in the simulator. The plan is to be able to build files loadable into the SIMH simulator using the "load" console command. Then we can use simh to run the software or to single step it. No operating system needed for that.Load file formatSimh can load into memory files representing a paper tape image. Yup, you have read it well. Punched paper tape. Now we are talking about classic computing! We can find the format of those images reading the pdp11_sys.c source file of the simh distribution. The code is in a function called sim_load. The comments block of that function describes the file format, which is not very complicated. The file is composed by byte blocks, each one of them preceded by a header and followed by a checksum. The last block is en empty one (just header and checksum). The structure of the header is as follows: Offset Length Datatype Content 0 1 char Fixed value: 1 1 1 char Fixed value: 0 2 2 word Size of the data block, in little endian format 4 2 word Load address for that block, in little endian formatThe checksum is computed adding every byte value of the block including the header and taking the 2's complement of the low order byte of the result. In other words, the negative value of the low order byte taken as an unsigned character.The last (empty) block also contains a
