THE PERM CIS-URALS IN 5th–7th CENTURIES: RECONSTRUCTION OF THE SETTLEMENT SYSTEM USING GIS

The article on the base of GIS-technologies reconstructs the tribal settlement system of the “Harin time” (5th–7th centuries) in the Perm Cis-Ural region. The basis for reconstruction is materials of 45 sites, forming five territorial groups. Each of these groups can be interpreted as a community (tribe) settlement area with internal economic unity. The comparative analysis of topographical peculiarities of the sites location, specifics of space organization, population dynamics, probable population size, communication links of groups made it possible to distinguish two types of adaptive strategies of human interaction with the environment. The first type has a producing economy (cattle-breeding) as its basis. This type was situated within the Tuisko-Poludenskaya and Sylvenskaya groups. The location of the settlements on the terraces above the floodplain in groups of two or three villages at some distance (about 3 km) from the necropolis is typical for this type. There are two or three groups of settlements within one territory, the distance between groups is about 6 km. The boundaries of the territory can be marked by hillforts, making up a single defensive / signal line. The second type is oriented to the appropriating economy — hunting and gathering — and was typical for the northern territories of the region (the Lologskaya, Gainskaya and Velvinskaya groups). The location of cemeteries near settlements (no more than 1 km) is typical for these territories. In this case, one cemetery often adjoins one village. There are from one to three or more such groups within the territory. The distance between them is 3–4 km. As a rule, there is one single hillfort in the territorial groups. In the first type, we can see the prevalence of local “Glyadenovo” traditions, and in the second — of foreign “Kharino” ones.

Moving Average Convergence-Divergence (MACD) Trading Rule: An Application in Nepalese Stock Market "NEPSE"

There are two types of analysis done for a stock market. One is fundamental analysis, where an investor looks at an intrinsic value of the stock, and another is technical analysis, where investors determine the future trend of the market looking at the current pattern or trend of the market. This paper is focused on one of the technical analysis tools, i.e., Moving Average Convergence-Divergence. It is a tool based on the three exponential moving average (9-12-26 EMA Rule). The MACD analysis, with the help of a single line, was helpful to find out the exact bullish and the bearish trend of the Nepse. A signal line is a benchmark to determine the stock market moving either to a bullish or bearish trend. It can help an investor, where the market is going in a direction. A market convergence, divergence, and crossover were better identified with the help of the MACD histogram. The paper found that the Nepse return was stable for a very minimal period from 1998-99 to 2019-20. The shift from the bullish to bearish or vice-verse were seen easily identified with the help of a MACD histogram. Finally, a better-combined knowledge of moving average and candlestick chart analysis will help an investor, to put a clear picture of a market trend with the help of MACD analysis.

Finite Ground CB-CPW Bandpass Filter using Vertically Installed Coupled Open-ended Stubs

In this paper, a conductor backed coplanar waveguide (CB-CPW) 3rd order bandpass filter is designed using coupled open-ended stub resonator placed vertically to the signal line. Vertically loaded open ended stubs are designed at quarter wavelength so as to behave like a short circuit at the input terminal thus giving a band-accepted response with lesser metallic area or minimum size. Four such coupled open ended resonators are placed in series and also in closely manner to provide greater field confinement of the proposed bandpass filter. The bandpass filter is designed for a center frequency of 2.5 GHz with FBW of 97.89%, insertion loss of <0.5dB, rising and falling edge selectivity of 30.75 dB/GHz and 27.01dB/GHz respectively with a wide stopband of around 4GHz after the desired passband. Further to validate the design technique six such resonators are placed to obtain 5th order bandpass filter.

Relationship of T2 Value of High-signal Line on MRI to the Fragment in Osteochondral Lesion of the Talus

Background: Magnetic resonance imaging (MRI) is useful for evaluating the stability of an osteochondral lesion of the talus (OLT). A T2 high-signal line between the fragment and its bed on MRI is known as a reliable indicator of an unstable lesion. However, the lesion exhibits various conditions even if a T2 high-signal line is observed. The purpose of this study was to evaluate the relationship between the T2 value of a high-signal line and the condition of the area between the fragment and its bed in OLT. Methods: T2 values of the T2 high-signal line and those of joint fluid were measured from preoperative MRI images in 46 ankles with OLT and the T2 ratio (high-signal line / joint fluid) was calculated. The relationship between the T2 ratio and CT, arthroscopic, and histologic findings was examined. Results: The mean T2 ratio was 0.48. T2 ratios of cystic lesions (0.62) or bone absorption (0.67) in the bed were significantly higher than those without a cyst (0.40) or no absorption (0.40). The T2 ratio of an unstable lesion (0.51) was significantly lower than that of a stable lesion (0.29). In histologic findings, there were 2 separate patterns: chondral and subchondral bone separations. The T2 ratio of the chondral separation (0.60) was significantly higher than that of bone separation (0.48). Conclusion: This study showed that the T2 ratio on a high-signal line was a predictor of stability, cyst, and bone absorption in OLT. Level of evidence: Level III, comparative series.

MACD technical indicator study and software implementation of decision function

Technical analysis is the study of the dynamics of the main market indicators by the availability of graphical methods in order to predict the future directions of their movement.The task of technical analysis to determine the current direction of the market.Most analysts use figures to characterize the lines of resistance, support, turn and the emergence of trends.The dynamic indicator MACD is classified as a trend - this parameter can be used to judge the ratio between a pair of sliding average prices. The indicator is constructed taking into account the difference between two EMAs with periods of 12 and 26 days. For more accurate drawing of the best places for a deal (sale or purchase), an additional (signal) line can be plotted from the MACD-Line with nine exponential average-forks from the MACD-Line with mandatory anti-aliasing (the default setting is 9).As a result of the work, the possibilities of using the MACD technical indicator were analyzed and the function for making decisions based on the logic of the advisor “buy or not” for the two exchanges of the Exmo and Poloniex cryptocurrencies was implemented programmatically.The use of MACD - indicator, as well as any other indicator, can sometimes be Su-Conducted by false signals. Therefore, for more successful trading in the stock and foreign exchange markets, it is best to use the MACD indicator in conjunction with other indices, the indicators of which will confirm the correctness of the chosen item.
