Nonlinear equality constraints are turned into inequality constraints to be satisfied by all iterates and the maximum of the objective functions is replaced by an exact penalty function which penalizes nonlinear equality constraint violations only.
The user has the option of either requiring that the modified objective function decrease at each iteration after feasibility for nonlinear inequality and linear constraints has been reached monotone line search , or requiring a decrease within at most four iterations nonmonotone line search.
In the first one monotone line search , a certain Armijo type arc search is used with the property that the step of one is eventually accepted, a requirement for superlinear convergence. Click it and wait a LONG time. When done, it should reboot into 5.
In that case, a power cycle may be required to get it back up and running. Assets 11 BBB Assets 7 BBB Some wifi adapters are taking a while for the Linux kernel to detect and initialize. FPP 5. We tried to keep it familiar to FPP users, yet "new and fresh". New "Wizard" on first startup to help configure FPP for the first time Troubleshooting page updated to run commands asynchronously and provide direct links to needed results.
Display testing page updated to provide easier adjustments to channel ranges and test settings MultiSync Page updates to provide faster updates and much more information New Privacy settings to prevent callouts to 3rd party sites for vendor logos, statistics, etc Requires location Latitude and Longitude to be set. Expose the host description setting on the System settings tab when running in docker since the network settings page is not shown.
See the API conversion guide for more information "Bridge mode" has been removed. Instead, if e1. Any incoming channel data will override what is loaded from a sequence. This allows combining pre-rendered sequence data with live data. All lower case letters and the most common punctuation can be sent in just one symbol , and all other characters the total alphabet contains characters in just two symbols. The alphabet is listed below. This is a simple example of a Varicode , where it takes less time to send the more common characters.
RTTY has only one bit of information per symbol, 7. No Sync Another important factor in the design of FSQ is that no synchronising process is required to locate and decode the received characters. Lack of sync means that reception is much less influenced by propagation timing changes that affect almost all other modes, since timing is quite unimportant to FSQ; it almost completely eliminates impulse noise disruption; and it also contributes to very fast acquisition of the signal decoding reliably within one symbol of start of reception.
Fast acquisition removes the need for addition of extra idle characters at the start of transmission, and this leads to a very slick system.
Add high resistance to QRM and QRN, thanks to the low baud rate, and you have a system so robust that it does not need error correction. It will operate from 2 baud to 6 baud, and anywhere in-between, with no changes to settings. The speed tolerance of FSQ is very wide, in excess of This is completely unique to FSQ, and gives operators great flexibility. The slower speeds are more robust and slightly more sensitive. Four sending speeds are provided, 2, 3, 4.
While the default speed is 6 baud, 4. You don't use 'overs' as you would with a conventional digital or voice mode. It is highly suited to net operation. You just type a sentence and press Enter. Directed Messaging Option In addition, the FSQCall program, which operates FSQ, operates by default in an Active Selective Calling mode, which provides automated functions, and is also useful for net and emergency operation; as it provides network management, link establishment and order and reporting features.
It is now also widely used for chat QSOs because the protocol is easy to learn and it offers junk-free reception. Directed Messaging Selective Calling is described briefly below. Directed Telemetry Telemetry can also be directed to specific stations, or to all stations, and also to specific files at each station. Repeated telemetry frames sent to the same address and file places the data in the same file in sequential order. Telemetry can also of course be relayed, or sent from a third-party program via FSQCall.
The signals are analogue, of similar bandwidth to the FSQ digital transmissions. The transmissions can be used in Chat mode, and in Directed mode can be directed to specific or all stations for automatic reception. Pictures can be transmitted from file photos, scanned documents, drawings and live shots from a web-cam!
Here are some examples - 40m transmissions using 15W and a range of km. Directed File Transfer Files can be sent to a specific station, or all stations in range, and are saved automatically. The recipient is advised, and the sender notified if the file was saved safely. Files can be retrieved from a specific station, and you can also read brief or detailed listings of files available from any station running FSQCall V0.
File transfer is secure in that you can't over-write important files, and you can't read files from anywhere else but the Shared folder on the other station's computer. While the file content is limited to standard text, it could be any type, for example. HTML or.
