Статья посвящена сведениям автобиографической надписи вельможи Сематауитефнахта на т.н. Неаполитанской стелы конца IV в. до н.э. В ней приведены аргументы против устоявшегося мнения о том, что этот вельможа оказался в 340-330-е гг. до н.э. при дворе Великого царя и, может быть, участвовал в войне против Александра по собственной воле, в силу своей проперсидской позиции
Статья посвящена анализу двух египетских источников, возможно, отразивших ситуации контактов знатных египтян с Александром Великим.
This report serves as a guide to the agricultural policy shifts made by the Government of Jamaica that would be desirable in the context of the changing role of agriculture. It focuses on the central question of how to create within the context of fiscal austerity an enabling framework for agriculture that results in a more competitive sector, with prospects for growth and poverty alleviation in the future. The three major studies underpinning this report are an Agricultural Sector Support Analysis, a Climat Change Report and an Agricultural Taxation Report. This report synthesizes and expands on the elements in these studies that are most relevant to the policy choices facing the government in the context of its tax reform initiative.
One of the challenging issues of Enterprise Architecture (EA) in large companies is organizing processes of baseline EA development and change management under conditions of steady change that implemented and changed IT solutions introduce. The research paper describes the approach of developing and keeping relevant baseline EA description together with IT project teams using Solution Architecture models. The method is in process of implementation in one of the leading Russian oil and gas companies Surgutneftegas
The rapid growth of traffic and number of simultaneously available devices leads to the new challenges in constructing fifth generation wireless networks (5G). To handle with them various schemes of non-orthogonal multiple access (NOMA) were proposed. One of these schemes is Sparse Code Multiple Access (SCMA), which is shown to achieve better link level performance. In order to support SCMA signal decoding channel estimation is needed and sparse Bayesian learning framework may be used to reduce the requirement of pilot overhead. In this paper we propose a modification of sparse Bayesian learning based channel estimation algorithm that is shown to achieve better accuracy of user detection and faster convergence in numerical simulations.
A new approach to network decomposition problems (and, hence, to classification problems, presented in network form) is suggested. Opposite to the conventional approach, consisting in construction of one, “the most correct” decomposition (classification), the suggested approach is focused on construction of a family of classifications. Basing on this family, two numerical indices are introduced and calculated. The suggested indices describe the complexity of the initial classification problem as whole. The expedience and applicability of the elaborated approach are illustrated by two well-known and important cases: political voting body and stock market. In both cases the presented results cannot be obtained by other known methods. It confirms the perspectives of the suggested approach.
Речь идет о применении новых вероятностно-статистических моделей к сравнительному анализу разноязычных метрически организованных (стихотворных) текстов.
We have observed unusual plasma formations (UPFs) in artificial clouds of charged water droplets using a high-speed infrared camera operating in conjunction with a high-speed visible-range camera. Inferred plasma parameters were close to those of long-spark leaders observed in the same experiments, while the channel morphology was distinctly different from that of leaders, so that UPFs can be viewed as a new type of in-cloud discharge. These formations can occur in the absence of spark leaders and appear to be manifestations of collective processes building, essentially from scratch, a complex hierarchical network of interacting channels at different stages of development (some of which are hot and live for milliseconds). We believe that the phenomenon should commonly occur in thunderclouds and might give insights on the missing link in the still poorly understood lightning initiation process.
