国际自动化与计算杂志 , 2005,
Abstract: This paper presents a new approach for deriving a power system aggregate load area model (ALAM). In this approach, an equivalent area load model is derived to represent the load characters for a particular area load of a power system network. The Particle Swarm Optimization (PSO) method is employed to identify the unknown parameters of the generalised system, ALAM, based on the system measurement directly using a one-step scheme. Simulation studies are carried out for an IEEE 14-Bus power system and an IEEE 57-Bus power system. Simulation results show that the ALAM can represent the area load characters accurately under different operational conditions and at different power system states.

Abstract: Seventy-two male adult Wistar rats were divided into three groups and treated as follows. (1) PEMF stimulation group (PEMF group, n = 24): intravenously injected with lipopolysaccharide (LPS, 10 μg/kg) on day 0 and intramuscularly injected with methylprednisolone acetate (MPSL, 20 mg/kg) on days 1, 2 and 3, then subjected to PEMF stimulation 4 h per day for 1 to 8 weeks. (2) Methylprednisolone-treated group (MPSL group, n = 24): injected the same dose of LPS and MPSL as the PEMF group but without exposure to PEMF. (3) Control group (PS group, n = 24): injected 0.9% saline in the same mode at the same time points. The incidence of osteonecrosis, serum lipid levels and the mRNA and protein expression of transforming growth factor β1 (TGF-β1) in the proximal femur were measured 1, 2, 4 and 8 weeks after the last MPSL (or saline) injection.The incidence of osteonecrosis in the PEMF group (29%) was significantly lower than that observed in the MPSL group (75%), while no osteonecrosis was observed in the PS group. The serum lipid levels were significantly lower in the PEMF and PS groups than in the MPSL group. Compared with the MPSL and PS groups, the mRNA expression of TGF-β1 increased, reaching a peak 1 week after PEMF treatment, and remained high for 4 weeks, then declined at 8 weeks, whereas the protein expression of TGF-β1 increased, reaching a peak at 2 weeks after PEMF treatment, and remained high for 8 weeks.PEMF stimulation can prevent steroid-induced osteonecrosis in rats, and the underlying mechanisms involve decreased serum lipid levels and increased expression of TGF-β1.Osteonecrosis of the femoral head is the end point of a disease process that results in progressive collapse of the femoral head followed by destruction of the hip joint. It has been recognized as a side effect of the corticosteroid used to treat diseases such as Acute Respiratory Syndrome (SARS), Acquired Immunodeficiency Syndrome (AIDS) and Systemic Lupus Erythematosus (SLE) [1-3].

Abstract: The new features of multi core add the optimization space for MPI applications, and besides tuning MPI runtime parameters is a common practice perceived to optimize the MPI application performance. However, the best configuration of the runtime parameters not only depends on the underlying architecture of a specific multi-core cluster but also on the features of MPI application. We constructed and analyzed an effective tuning model bases on artificial neural network to automatically predict the near-optimal configuration of runtime parameters for any unseen input programs under the current multi-core cluster. Experimental results from two different benchmarks were presented to show effectiveness of our approach. We observed that the speedup gained by the predicted runtime parameters can averagely achieve 95% of the speedup gained by the best parameters configuration.
An identity related to Jordan's inequality
Jian-Lin Li
International Journal of Mathematics and Mathematical Sciences , 2006, DOI: 10.1155/ijmms/2006/76782
Abstract: The main purpose of this note is to establish an identity which states that the function sinx/x is a power series of (π2−4x2) with positive coefficients for all x≠0. This enable us to obtain a much stronger Jordan's inequality than that obtained before.

Tamkang Journal of Mathematics , 2002, DOI: 10.5556/j.tkjm.33.2002.303-308
Abstract: The object of this paper is to investigate some properties of the convex null operators which are defined for analytic functions. The result obtained here extends and sharpens some recent results due to Silvia [5], Ahuja and Jahangiri [1].
Notes on the starlikeness of an integral transform
Jian-Lin Li
Tamkang Journal of Mathematics , 2001, DOI: 10.5556/j.tkjm.32.2001.151-154
Abstract: Let $ A $ denote the class of normalized analytic functions in the unit disk $ D $. For $ f(z) in A $ and $ alpha > 0 $, let $ F_{alpha} (z) = int_0^z (f(t)/t)^{alpha} dt $ in $ D $. In this note, the author obtains the best constant $ eta (alpha) $ for each $ alpha in (0,3] $ such that Re$ { f'(z) (f(z)/z)^{alpha -1} } > eta (alpha) $ implies the starlikeness of $ F_{alpha} (z) $.
