Suhrawardi's Modal Syllogisms

Suhrawardi’s logic of the Hikmat al-Ishraq is basically modal. So to understand his modal logic one first has to know the non-modal part upon which his modal logic is built. In my previous paper ‘Suhrawardi on Syllogisms’(3) I discussed the former in detail. The present paper is an exposition of his treatment of modal syllogisms. On the basis of some reasonable existential presuppositions and a number of controversial metaphysical theses, and also by confining his theory to alethic modality, Suhrawardi makes his modal syllogism simple in a way that is without precedent

International Competitiveness—Where Pakistan Stands?

The concept of competitiveness has been widely accepted and has become a part of discussion in world-wide forums. Today global economy cannot be explained in the same manner as it was a few decades ago. Improved competitiveness of economies is a need of the day and ability to compete in the world market is of major concern. This paper attempts to assess the position of Pakistan in the International Competitiveness. As a survey paper, the concept, definition and the measurement of competitiveness have been analysed further to assess Pakistan’s position in the region. Competitiveness is linked with export performance of other trading and non trading countries. Pakistan’s export performance is analysed in this context. Lessons for Pakistan have been drawn on the basis of experiences of emerging economies. It has been concluded that countries can strengthen their export markets with the passage of time. They need to improve the governance as well as technological progress to increase high-tech exports. Developing countries like Pakistan start from low technology and with passage of time shift to improved technologies. Technology-based activities help improving export performance that brings competitiveness of a country. The paper also suggests a model to government of Pakistan which describes that high technology exports will be a result of extensive Research and Development (R&D) using human capital as an investment in the country. The success depends upon the combined efforts of the government, individuals and business initiatives both in public and private sectors.Competitiveness, Growth Performance

On the control aspect of laser frequency stabilization

Realization of frequency stable lasers is viewed as key to progress in many areas of research; therefore, the search for more effective techniques of frequency stabilization has intensified significantly in recent years. Investigating and validating the fundamental linewidth and frequency stability limits of a Nd:YAG laser oscillator, locked to a high finesse reference cavity in the microgravity and vibration-free environment of space, is the objective of a NASA project called SUNLITE at LaRC. The objective of this paper is to further investigate the application of feedback control theory in active frequency control as a frequency stabilization technique and determine the most appropriate control strategy to be used in general and particularly in the SUNLITE Project

Mathematical model for adaptive control system of ASEA robot at Kennedy Space Center

The dynamic properties and the mathematical model for the adaptive control of the robotic system presently under investigation at Robotic Application and Development Laboratory at Kennedy Space Center are discussed. NASA is currently investigating the use of robotic manipulators for mating and demating of fuel lines to the Space Shuttle Vehicle prior to launch. The Robotic system used as a testbed for this purpose is an ASEA IRB-90 industrial robot with adaptive control capabilities. The system was tested and it's performance with respect to stability was improved by using an analogue force controller. The objective of this research project is to determine the mathematical model of the system operating under force feedback control with varying dynamic internal perturbation in order to provide continuous stable operation under variable load conditions. A series of lumped parameter models are developed. The models include some effects of robot structural dynamics, sensor compliance, and workpiece dynamics

Rebalancing, Growth, and Development in a Multipolar Global Economy

Reduction of large and persistent external imbalances is currently a key focus of G-20 discussions. The paper argues that in a progressively multipolar world economy, the goals of global rebalancing, growth, and development are increasingly inter-linked. Growth-oriented rebalancing calls for emphasizing structural reforms and leveraging the role of developing countries in supporting strong and balanced global growth.Basel III, Imbalances, current account, global imbalances, g20, g-20, development, growth, structural reforms, developing countries

Do we face a global"capital shortage"?

The author of this paper assesses the medium- to long-term outlook for global demand and supply of capital. He reaches the following conclusions: 1) the demand for investment funds in developing countries will remain strong, but most increased demand will likely be met by domestic savings. Investment's share in GDP will probably rise in these countries, but so will saving's share, so their net claim on industrial countries'savings is likely to remain small. Of course, savings will not rise automatically. It is essential that policies, institution, and the economic environment be conducive to saving; 2) financial liberalization and integration of international capital markets will continue to give developing countries as a group improved access to private foreign capital. But whether specific countries attract and sustain such inflows will depend on their economic prospects and policies, including conditions that promote domestic saving and investment. Investments needs in developing countries are great, but"effective"demand for foreign capital will remain limited by the countries'perceived creditworthiness and viability; 3) most low-income countries will continue to depend mainly on official capital for some time. But official capital will likely be increasingly scarce, so these countries must identify their domestic resource mobilization and accelerate the policy reform needed to attract private investment; 4) the critical factor in alleviating pressure on global interest rates will be progress on fiscal consolidation in industrial countries, especially the reform of social security systems. Net capital flows from industrial to developing countries are much smaller than the budget deficits in industrial countries; and 5) international capital markets will tend to remain tight in the coming decade, but a severe global capital squeeze and a big increase in global real interest rates are unlikely if industrial countries continue fiscal consolidation. Without such consolidation, global real interest rates could rise well above already high recent levels of about 4 percent, with adverse consequences for all countries.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Capital Markets and Capital Flows,International Terrorism&Counterterrorism,Economic Theory&Research,Banks&Banking Reform,Macroeconomic Management,Environmental Economics&Policies,International Terrorism&Counterterrorism
