在伺服系统的传统设计方法里,关于前馈补偿量的选择,主要考虑的是补偿的精度和实现的代价,而没有定量考虑测量噪声的影响,本文从分析各种误差源入手,计算这些误差源对输出精度的影响,并且建立了用以衡量系统精度的评价函数,据此可对伺服系统里的前馈补偿量进行优选,文章对电视自动跟踪系统前馈补偿量的选择进行了较详细的讨论。  相似文献

The implications for African states of the recently created International Criminal Court should be carefully considered. There are far-reaching limitations placed on the ICC's jurisdictional scheme, both temporally as well as by the preconditions to the exercise of jurisdiction in the form of territoriality and nationality. The Court's powers may also be constrained out of deference to the grant of an internationally acceptable amnesty, and national courts may be constrained to recognise immunities from prosecution for high-ranking officials. These limitations need to be properly understood so that the ICC can be effectively utilised by African States to declare and act upon their commitment to the principle of individual criminal liability for those responsible for the most serious crimes.  相似文献

This article revisits Zimbabwe's land question from the vantage point of having been written five years after the ‘fast-track’ land redistribution programme was launched. Without belittling the accomplishments of land reform in the first 19 years of the country's independence, it is generally clear that the sweeping programme of 2000–2003, the most comprehensive of its kind, created a new paradigm. Clearly, the consequences will take many years to work themselves out through the country's political, economic and social fabric.

The article briefly defines what may be termed ‘old’ and ‘new’ versions of Zimbabwe's land question before outlining the salient aspects of the reform process itself. It then assesses the outcomes of the redistribution, the apparent lacuna between ‘land’ and ‘agrarian’ reform, and the debate that the reform process itself has kindled. Transforming land distribution into qualitative agrarian reform has proved an Achilles heel in the arguments put forward by the proponents of the fast-track programme. Finally, recommendations are provided as to what is necessary to secure land and agrarian reform in the short, medium and long term.  相似文献

This article assesses the prospects for a strategy of incrementalism to lead to achievement of the core bargain of the Treaty on the Non-Proliferation of Nuclear Weapons: non-nuclear weapon states' nuclear nonproliferation in exchange for nuclear weapon states' nuclear disarmament to the point of “global zero.” Game theory, prospect theory, and liberal international theory are used to evaluate the potential of a strategy of incrementalism. While separately each has insights to offer, it is when all three theoretical approaches are used in tandem that meaningful explanatory gains emerge. The article concludes that incrementalism probably cannot lead to complete nonproliferation and global nuclear zero. Instead, signal events (as described by prospect theory) are needed to “punctuate” incremental processes in negotiations (best explained by liberal international theory) in order to move past hindrances such as international structural constraints (exemplified by game theory) and the conservative risk-taking propensities of state elites (described by prospect theory).  相似文献

Based on the first-person account of coauthor Pierre Billaud, a prominent French participant, this article describes for the first time in such detail the history of the development of the French hydrogen bomb in the 1960s and the organization of military nuclear research in France. The authors illustrate the extent to which French defense and governmental authorities did not support research on thermonuclear weapons until 1966. Billaud, a project insider, relates the historical episodes that led to France's successful 1968 thermonuclear test, including the names of the individuals involved and how a timely tip from a foreign source hastened the success of the first H-bomb test.  相似文献

The mandate to promote human rights in Africa is a challenging one and the African Commission on Human and Peoples' Rights, whose mandate it is, will have to use partnerships, such as NEPAD and other supportive multilateral institutions to fulfil it. The African human rights enforcement mechanism can only be as strong as the African peoples themselves make it. This paper examines the African Commission on Human and Peoples' Rights and looks at the role of the Commission in the New African dispensation following the adopting of the Constitutive Act of the African Union and the adoption of the New Partnership for African Development (NEPAD).  相似文献

How do we assess the health of international regimes? Many analysts have insisted recently that the nuclear nonproliferation regime is in urgent need of repair or that it should even be discarded because of its supposed ineffectiveness. However, it is essential that statements about the regime being in crisis be scrutinized for veracity and utility. While the spread of nuclear weapons poses an undeniable and serious threat to international security, a mistaken crisis mentality with respect to the regime could lead to rash attempts to alter it in unnecessary or ineffective ways or, at worst, to discard it completely. This paper returns to a theoretical framework that differentiates regimes, across both issue areas and time, to provide a more specified evaluation of regime health. By disaggregating the nuclear nonproliferation regime and assessing the individual and interactive health of multiple dimensions, a number of dimension-specific, regime-strengthening policy recommendations emerge.  相似文献
