Sine, triangular and square wave alternating currents were used to anaesthetize young buffalo calves. Central venous pressure, systolic and diastolic blood pressure and circulatory rate were monitored before, during and after application of currents. The square and triangular wave current produced a significant (P less than 0.01) increase in central venous pressure, mean systolic and diastolic ...
Variable frequency devices are widely used in many power systems. A current tracking based VFD is proposed in this paper. The output current is firstly fed back and compared with a standard sine wave, the difference of them is then used for a PI regulator to control the PWM signal, so as to change the output current accordingly to make it approach the standard sine wave. Simulation and experime...
The symmetric space sine-Gordon models arise by conformal reduction of ordinary 2-dim σ-models, and they are integrable exhibiting a black-hole type metric in target space. We provide a Lagrangian formulation of these systems by considering a triplet of Lie groups F ⊃ G ⊃ H . We show that for every symmetric space F/G, the generalized sine-Gordon models can be derived from the G/H WZW action, p...
PCR primers for the detection of materials derived from ruminants, pigs, and chickens were newly designed on the basis of sequences of the Art2 short interspersed repetitive element (SINE), PRE-1 SINE, and CR1 long interspersed repetitive element (LINE), respectively. These primers amplified the SINE or LINE from total DNA extracted from the target animals and from test feed containing commerci...
Abstract In this paper a new estimator for the measurement of the rms value of a noncoherent sampled sine-wave is proposed. The key feature of this estimator is that the sine-wave offset, a priori estimated, is removed from the sine-wave. A formula used to estimate the sinewave offset is also given in the paper. It has been proved by means of computer simulations and experimental results that...
Producing and manipulating the sine wave function is a common problem encountered by circuit designers. Sine wave circuits pose a significant design challenge because they represent a constantly controlled linear oscillator. Sine wave circuitry is required in a number of diverse areas, including audio testing, calibration equipment, transducer drives, power conditioning and automatic test equip...
Abstract. We investigate the low-energy properties of a generalized quantum sine-Gordon model in one dimension with a self-dual symmetry. This model describes a class of quantum phase transitions that stems from the competition of different orders. This SU(N ) self-dual sine-Gordon model is shown to be equivalent to an SO(N )2 conformal field theory perturbed by a current-current interaction, w...
By studying the internal Riemannian geometry of the surfaces of constant negative scalar curvature, we obtain a natural map between the Liouville and the sine–Gordon equations. First, considering isometric immersions into the Lobachevskian plane, we obtain an uniform expression for the general (locally defined) solution of both the equations. Second, we prove that there is a Lie– Bäcklund trans...
