Gross Final Product and GFP-Driven Economic Growth

After analyzing the defects of gross domestic product(GDP) as a statistical indicator, this paper identifies and defines the concept of gross final product(GFP), emphasizing the attribute of GFP as the final product of a natural process and the actuator of the entire economic system. The paper also investigates the roles of foreign trade, production investment, public goods and private goods in economic growth under the GFP perspective, and explores the possibility for the GFP analytical framework to explain the economic growth process.

The Research of Mutual Economic Relations of the World Countries on the Basis of Input-Output Table

＂Input-output＂ table which was designed for solution of mutual relation （impact） problem is a widely applied tool in the world for conducting economic analysis and forecasting. One of the most important problem of today＇s world is to prevent financial-economic crises in several countries of the world and especially in Eurozone countries where it is still ongoing. Input-output balance tables were prepared by modifying input-output table based on relevant economic indicators of the biggest countries of economy in the world as well as simulations were conducted by designing several balance models （mutual impact of GDP and change in general output of countries, mutual impact of added value and prices, mutual impact of GDP and work places）. Level of coverage of relevant indicators used in analysis on the countries of the world were tested on the basis of statistic methods and assessed. It was identified that, level of confidence of the coverage in designed model on world economy is higher than 95%. These models enable to analyze and forecast possible changes in world economy caused by changes which took place in economic conjecture of other big countries of the world, especially in USA, Japan, Germany, and China. It should be noted that, model＇s system was automatized in EXCEL system with the purpose of simplifying simulations and conducting analysis and increasing efficiency on the usage of models.

Spreadability of powders for additive manufacturing:A critical review of metrics and characterisation methods

Powder bed fusion methods of additive manufacturing (AM) require consistent, reproducible, and uniform layers of powder for the reliable production of high-quality parts, where properties of powder are central to achieving this. Among these properties, powder flowability and spreadability play critical roles in determining the quality of these powder layers.While extensive research has been conducted on powder flow and spreading behaviour, and on their characterisation, there is little critical comparison and review of these terms in the context of AM. Such a review is necessary to further develop and enhance our comprehension of spreading dynamics and its relation to powder properties in AM systems.This review paper aims to build a coherent understanding of the correlation between powder characteristics and spreading in powder based additive manufacturing and its impact on manufactured parts. It highlights the current progress in comprehending spreading dynamics, the influence of powder characteristics, environmental conditions, spreading system, and the development of testing tools to assess powder spreadability. Furthermore, the paper critically discusses the challenge of finding appropriate quantitative metrics and recent advances in the use of standardised methods for evaluating powder spreadability.

Cubic and Quartic Higgs Couplings of Higgs Potentials and CP Phases

We derive cubic and quartic couplings of the Higgs singlet extension of the SM and the two Higgs doublet model. We also examine the number of CP violated couplings in a model with n Higgs doublet model and a model with ns Higgs singlets and ndHiggs doublets. We conclude that in order to reconstruct the Higgs potential with multi Higgs fields at the LHC and future colliders, to detect the cubic/quartic couplings is necessary.
