A theoretical analysis upon the four-dimensional (4D) spatio-temporal temperature dependent dynamics of 888 nm pumped Nd:YVO 4 dual-rod laser is established, which is valid in both continuous-wave (CW) and acousto-optic (AO) Q-switched pulse lasers conditions.Our model can accurately solve the 4D thermal generation Lip Gloss and temperature evoluti

In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the arm corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC code pair) in a joint source-channel coding (JSCC) system.Specifically, we pre-set the girth of the
