This program allows you to record lectures and attach written summaries. To make a lecture summary several rich-text fields are provided: course, subject, date, lecturer, digest and notes. There is also an option to print the summary. Built-in audio recorder comes with real-time OGG audio compression, an editor for making cut-outs, voice operated recording mode and transcription playback mode. All recordings are 8-bit, mono, with 44KHz as the default sampling rate, but you can also use 22KHz and 11KHz if you want to save on space. The program keeps both text and audio in the same lecture file that you can easily share. Of course, if that is necessary you can export your recordings to standard sound files and use them in other programs. Sound file import option is available too. Lecture file size can go up to 2GB and that is sufficient for more than 12 hours of uncompressed recording with the highest sampling rate. Lecture Recorder can work with all sound sources you have on your computer. Note: if your microphone can not pick up lecturer's voice try to find one designed for conferences.

WirelessMon 2.0 enables a person to detect and monitor Access Points (AP) on any wireless (WiFi) networks within range. The program provides substantial information regarding each SSID it locates including whether the AP is secure (or not) and its availability for use.

A live 'channel usage' chart provides information on the level of traffic for each available channel. This information will assist network managers by indicating channels that could be used to reduce interference and improve throughput.

Users of the Professional Edition will have the additional bonus of being able to generate 'coverage maps' based upon the signal strength of all detected APs. To use this function, users need to import a map created by an another application (e.g. scanning). Once the map is loaded, users can either plot points manually on the map, or use a Global Positioning System (GPS) device. If done manually, the user selects a point on the map and the program automatically stores information on every AP it can detect there. GPS users need to establish two reference points, then they can leave it to the program to detect their location on the map and store the AP information for each point.

Network managers, laptop users and wardrivers will all find WirelessMon 2.0 to be the perfect tool for their wireless network requirements.

Trading software for all instruments on every market! Optimal Trader combines technical analysis with artificial neural networks and modern signal processing. Many indicators have been improved with new technology. A large database with stocks, mutual funds and indices is available for free.
Features:
*Optimal Trader's Combined Analysis Model merges the buy and sell signals of the active models into one buy or sell signal. The Combined Analysis Model produces more stable buy and sell signals than single models buy and sell signals.
*Pick winning stocks or funds with Portfolio Scan based on your criteria and neural network forecasting.
*Neural Network Forecasting. Neural networks have a high ability in detecting patterns in stock price development.
*In-house developed adaptive moving average filter for most indicators. Optimal Trader Adaptive Mean Average filter(OptAMA), reacts fast on major price changes and smoothes noise efficiently in stock data. The result is clearer signals in many models and fewer erroneous signals when the trend is uncertain.
*Optimal Trader can make a backward analysis (step-by-step Back Testing) to evaluate the results of following a certain stock with a certain model.
*Autoselect Models
*Robust Optimization and Robust Parameters

The filter adds artificial noise of one common types (equidistributed, normaldistributed,
colour stains, echo signal) to video stream. It can be used for testing, debuging and comparison
of various denoising filters.
'Settings' dialogue box allows to select type of noise to generation.
Noise intensity can be specified for each colour component (the filter uses YCrCb colour space).
Individual noise parameters also can be changed for some noise types.
