How Gerrymandering can influence electoral results on a Voting system # Nonproportional and semiproportional methods | non-proportional system. Example for a state with 3 equally sized districts, 15 voters and 2 parties: Plum ( squares ) and Orange ( circles ). In ( a ), creating 3 mixed-type districts yields a 3 – 0 win to Plum — a disproportional result considering the state-wide 9: 6 Plum majority. In ( b ), Orange wins the urban district while Plum wins the rural districts — the 2-1 result reflects the state-wide vote ratio. In ( c ), gerrymandering techniques ensure a 2-1 win to the state-wide minority Orange party.

# For a given orbit, the ratio of the cube of its semi-major axis to the square of its period is constant.

Jerrum, Valiant, and Vazirani showed that every # P-complete problem either has an FPRAS, or is essentially impossible to approximate ; if there is any polynomial-time algorithm which consistently produces an approximation of a # P-complete problem which is within a polynomial ratio in the size of the input of the exact answer, then that algorithm can be used to construct an FPRAS.

# In asynchronous data transmission, the ratio of ( a ) the absolute value of the maximum measured difference between the actual and theoretical intervals separating any significant instant of modulation ( or demodulation ) from the significant instant of the start element immediately preceding it to ( b ) the unit interval.

# The ratio of power gain between the front and rear of a directional antenna.

# At a discontinuity or impedance mismatch, e. g. in a transmission line, the ratio of the incident power to the reflected power.

# The ratio of ( a ) total received power, i. e., the signal to ( b ) the noise-plus-distortion power.

# The ratio of ( a ) the power of original modulating audio signal, i. e., from a modulated radio frequency carrier to ( b ) the residual audio power, i. e., noise-plus-distortion powers remaining after the original modulating audio signal is removed.

# The contention that occurs when a terminal and data circuit-terminating equipment ( DCE ) specify the same channel at the same time to transfer a call request and handle an incoming call.

# The condition that occurs when a trunk or channel is seized at both ends simultaneously.

# The data signaling rate is given by where m is the number of parallel channels, n < sub > i </ sub > is the number of significant conditions of the modulation in the i-th channel, and T < sub > i </ sub > is the unit interval, expressed in seconds, for the i-th channel.

# For serial transmission in a single channel, the DSR reduces to ( 1 / T ) log < sub > 2 </ sub > n ; with a two-condition modulation, i. e. n = 2, the DSR is 1 / T, according to Hartley's law.

# For parallel transmission with equal unit intervals and equal numbers of significant conditions on each channel, the DSR is ( m / T ) log < sub > 2 </ sub > n ; in the case of a two-condition modulation, this reduces to m / T.

# A basic communications channel with the necessary bandwidth but without enhanced or value-added services.

# the signals from each channel are added together,

# the gain of each channel is made proportional to the rms signal level and inversely proportional to the mean square noise level in that channel.
