Research Trend Topic Area on Mobile Anchor Localization: A Systematic Mapping Study

Localization in a dynamic environment is one of the challenges in WSN localization involving dynamic sensor nodes or anchor nodes. Mobile anchors can be an efficient solution for the number of anchors in a 3-dimensional environment requiring more local anchors. The reliability of a localization system using mobile anchors is determined by various parameters such as energy efficiency, coverage, computational complexity, and cost. Various methods have been proposed by researchers to build a reliable mobile anchor localization system. This certainly shows the many research opportunities that can be carried out in mobile anchor localization. The many opportunities in this topic will be very confusing for researchers who want to research in this field in choosing a topic area early. However, until now there is still no paper that discusses systematic mapping studies that can provide information on topic areas and trends in the field of mobile anchor localization. A systematic Mapping Study (SMS) was conducted to determine the topic area and its trends, influential authors, and produce modeling topics and trends from the resulting modeling topics. This SMS can be a solution for researchers who are interested in research in the field of mobile anchor localization in determining the research topics they are interested in for further research. This paper gives information on the mobile anchor research area, the author who has influenced mobile anchor localization research, and the topic modeling and trend that potentially promissing research in the future. The SMS includes a chronology of publications from 2017-2022, bibliometric co-occurrence, co-author analysis, topic modeling, and trends. The results show that the development of mobile anchor localization publications is still developing until 2022. There are 10 topic models with 6 of them included in the promising topic. The results of this SMS can be used as preliminary research from the literacy stage, namely Systematic Literature Review (SLR)

THE THEORETICAL-METHODOLOGICAL BASIS OF THE MODEL OF MACRO-ECONOMIC FORECAST, OF LABOUR MARKET AND POPULATION

During the last decade of the 20th century, modeling the macro-economic evolutions and implicitly modeling the evolutions in the social insurance systems, including and especially the pension systems, gained a very strong “anchor”, which allowed and allows at present the realization of multiple evolution scenarios, with a pretty big probability of achievement. This anchor, or better said this anchor-variable is the “inflation rate”, usually calculated as the consumption price index, respectively as its percentage variation from one period of time to another. The last decades of the 20th century and the first five years of the 21st century were characterized by an extremely accelerated rhythm of innovation, as well as by an acceleration and a multiplication of capital flows, which practically led to the phenomenon known as “economy globalization” or simply as “globalization”, as it extended outside the economical sphere towards all the spheres and sectors of the social life. This process has been accelerated by the “transition from plan to market” of the economies from Central and Eastern Europe, as a consequence of the fall of the totalitarian communist system, which dominated this part of Europe half a century, and of the end of the era known as “the Cold War”. The economic globalization movement, together with the transition from plan to market as well as with China’s entering into the international economic circuits, grew enormously the investment possibilities and thus the possibilities of placing the capital accumulated in the western countries during the autarchy period which characterized the Cold War era.labor market, pension system, globalization

Analysis of the phenomenon of speculative trading in one of its basic manifestations: postage stamp bubbles

We document and analyze the empirical facts concerning one of the clearest evidence of speculation in financial trading as observed in the postage collection stamp market. We unravel some of the mechanisms of speculative behavior which emphasize the role of fancy and collective behavior. In our conclusion, we propose a classification of speculative markets based on two parameters, namely the amplitude of the price peak and a second parameter that measures its ``sharpness''. This study is offered to anchor modeling efforts to realistic market constraints and observations.Comment: 9 pages, 5 figures and 2 tables, in press in Int. J. Mod. Phys.

Experimental Study of Pullout Capacity of Stars Plate Anchor

This study aims to investigate various types of anchors with 5, 4, and 3 plates star in which its section area and equivalent diameter constant. We performed experimental test by modeling anchor with 5 mm thick and 30 mm width. Pull test was subjected on the anchor in the compacted soil where the anchor was placed in the various depths, 300 mm, 600 mm, and 900 mm. The test results indicated that anchor plate with longer equivalent diameter yield larger pull stress. The depth of anchoring is also significant factor to pullout capacit
