PEAK COVARIANCE STABILITY OF A RANDOM RICCATI EQUATION ARISING FROM KALMAN FILTERING WITH OBSERVATION LOSSES

We consider the stability of a random Riccati equation with a Markovian binary jump coefficient. More specifically, we are concerned with the boundedness of the solution of a random Riccati difference equation arising from Kalman filtering with measurement losses. A sufficient condition for the peak covariance stability is obtained which has a simpler form and is shown to be less conservative in some cases than a very recent result in existing literature. Furthermore, we show that a known sufficient condition is also necessary when the observability index equals one.

CONSTRUCTIVE KISSING NUMBERS IN HIGH-DIMENSIONAL SPACES

In the present paper, we focus on constructive spherical codes. By employing algebraic geometry codes, we give an explicit construction of spherical code sequences. By making use of the idea involved in the proof of the Gilbert-Varshamov bound in coding theory, we construct a spherical code sequence in exponential time which meets the best-known asymptotic bound by Shamsiev and Wyner.     

Nd:YAP激光晶体偏振光谱的测量与分析

从分析NdYAP和NdYAG两种激光晶体的优缺点入手,指出前者的各向异性能够提供许多特殊的用途,讨论了它的能级和光谱特性,详细介绍了该晶体偏振吸收谱、偏振受激发射截面谱和荧光寿命的测量方法,并给出了两块沿a轴切割的NdYAP晶体的测量结果和分析.这些分析与测量反映了NdYAP晶体各向异性的特性优势,将使其在固体激光器应用领域可以成为传统NdYAG晶体很有潜力的替代者.
