    WebLogger is a php-based application designed to help Amateur Radio operators log radio traffic. WebLogger targets traffic related to community and public service such as skywarn, assisting in natural disasters and other emergency situations. WebLogger is written in PHP and uses MySQL on the back end to store information.

    CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h).

    Returns equivalent IIR coefficients for an analog RC filter Usage: [B,A] = RC_FILTER(r, c, fs, type); R is the resistance value (in ohms) C is the capacitance value (in farrads) FS is the digital sample rate (in Hz) type is a character string defining filter type Choices are: 'high' or 'low' This function uses a pre-calculated equation for both of these circuits that only requires the resistance and capacitance value to get a true digital filter equivalent to a basic analog filter.

    The aim of this toolbox is to compute blocking probabilities in WDM networks. This work was based on [1], [2], [3], [4] and user is referred to those papers for deeper study. Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources.

    ScaleTime - fast linear matrix interpolation I have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames. For this task, the direct approach with Matlab's INTERP1 works, but it is slow: interp1(1:size(Y, 1), Y, Ti, '*linear') Cutting Y to blocks of 1000 frames at first accelerates the computing, but encreases the complexity.

    ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate (BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes 2 transmit (Tx) and arbitrary number of receive (Rx) elements. If Rx=1 (one receive element) the ALAMOUTI is transformed to the order 2 transmit diversity scheme with Maximum Ratio Combining (MRC).

    PHPMQ is an Open Source serverless messaging toolkit for PHP, giving the PHP developer ability to perform JMS operations such as sending and receiving messages on queues and topics while ensuring delivery and enabling persistent messaging. Connecting PHP to a messaging bus is equivalent to connecting it to a database; the possibilities for using this infrastructure are endless, PHP developers using the PHPMQ will be able to communicate with other elements in the messaging bus, thus breaking the barrier between the two worlds.
