    학위논문(박사) - 한국과학기술원 : 기계공학과, 2017.8,[viii, 135 p. :]This dissertation is concerned with the dynamic hardening and fracture behaviors of metallic materials at a wide range of strain rates from 10310^{-3} /s to 10610^6 /s. The main outcomes of this dissertation are: (i) experiments to obtain hardening behaviors and fracture strains at a wide range of strain rates from 10310^{-3} /s to 10310^3 /s and temperatures from 25C\circ C to 200C\circ C(ii) consideration of thermal softening effect at various strain rates due to large plastic deformation(iii) development of a rate and temperature dependent constitutive model to describe strain rate hardening and thermal softening behaviors(iv) investigation of a novel systematic procedure to calibrate hardening behaviors at ultra-high strain rates ranging from 10410^4 /s to 10610^6 /s where hardening behaviors are difficult to acquire from conventional experiments(v) development of a strain rate dependent fracture criterion which can decently estimate experiment results at various strain rates and loading pathsand (vi) prediction of sequential deformed shapes and fractured shapes of projectiles from Taylor impact tests for different metallic materials.한국과학기술원 :기계공학과

    The Tax Disadvantage Of Ordinary Income: An Event Study On The Legislative Process Of JGTRRA

    No full text
    The Jobs Growth and Tax ReliefReconciliation Act of 2003 (JGTRRA), signed into law by President George W.Bush, was a significant legislation in recent tax history.  As the tax rates on capital gains anddividends are reduced to a historical low of 15%, U.S. stock prices haveincreased and the cost of equity capital declined after its passage.  In contrast to the dividends and capital gainsthat receive preferential tax rates under JGTRRA, yields from U.S. Treasurybill remain tax-disadvantaged as ordinary income at a top marginal rate of 35%. Using an event study approach based ontwo years of Treasury yield observations, the author examines Treasury yield reactionsto major legislative events surrounding the passage of JGTRRA.  The result suggests that a tax policyintentionally favoring dividends and capital gains over ordinary income may unintentionallypush up yields in the Treasury bill market, thereby affecting the cost ofgovernment borrowing

    National systems of technology transfer of BRICS countries: features of formation

    No full text
    The article considers the features of creation and development of organizational systems of technology transfer in the BRICS member countries (Brazil, Russian Federation, India, China, South Africa), interaction of participants in the innovation process. The author identifies the significant role of the regional component in the formation of effective national innovation systems. The purpose of the article is to analyze the national innovation systems of the BRICS member countries, since each of these countries has gone its own way of innovative development, justified by regional characteristics. Based on the analysis of transfer systems operating in the BRICS countries, the author identifies key and most promising areas for the development of the integration of the scientific and educational, production spheres and the state in order to form special mechanisms for organizing innovative processes that ensure effective interaction between all its participants, contributing to the formation of competitive high-tech products
