Aimed to two major problems: one is not decidable and the other is no clear semantics. We construct a framework with explicit representation and formal semantics of goalsgoal description logics, which integrates two types of goals: declarative goals and procedural goals into one concept based on description logics. In addition, the goal plan is defined and analyzed, and some reasoning problems, such as goal consistency and goal satisfiability, are discussed. Contrary to traditional ways of goal description, GDLs can bridge the gap between theory and practice in a natural way.
针对传统的目标描述中存在的不可判定性以及没有清晰的语义等问题,在描述逻辑(description logics,DLs)上,将宣称型和过程型2种类型的目标描述有机地整合在一起,从而构建了具有清晰语义与可判定性的形式化框架--目标描述逻辑(goal description logics, GDLs),在此基础上,定义了该框架下有关规划规则;建立了可用于判定目标一致性、目标可满足性的方法,与传统的目标描述方法相比,目标描述逻辑为主体领域模型提供了一种更有力的形式化工具,同时为智能主体的模型和设计提供了很好的理论工具。

Base on the threshold voltage model presented, an intrinsic drain current model in strong inversion region is developed, which can describe the short-channel effects such as DIBL and charge-sharing effect well, and give special considerations for mobility, velocity saturation, channel length modulation and quantum effect. Based on the front interface surface potential model, a formula of unified inversion charge is derived, and an intrinsic drain current model in middle inversion region is developed.

We investigate phenomenologically effects of the flavor-dependent quarkonia annihilation on the meson-meson mixing, and find that corrections due to the flavor-dependent quarknoia annihilation can be described by the constituent quark masses in the mixing model which holds for all the meson nonet. We also study the relation between Regge trajectory and meson spectrum, and therefore concluded that the quasi-linear Regge trajectory with the requirements of additivity of intercepts and inverse slopes can describe the meson spectroscopy with good accuracy, and it also holds for the radial excited mesons except for the bbbar mesons.

Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.
由于信元抖动的复杂性,非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能,以及在目的节点的源定时恢复问题作了较为全面的研究。首先,文中描述了CBR业务流的信元抖动,并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后,采用了精确的数学模型和分析方法,有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法,在性能分析中,我们成功地完成了CBR业务流信元抖动的功率谱分析,使得不但可以从频域定性地认识信元抖动的能量分布特性,而且还可以定量地求出信元抖动的均方根值(rms:root-mean-square),以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中,我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流,并基于这一模型进行了CBR业务流中间节点的初步排队分析。
