The paper proposes an architecture of a test structure for verifying libraries of standard cells in silicon, based on a pipeline-distributive approach. This approach allows reducing both the number of inputs and outputs and the area occupied by the test structure on a crystal in comparison with traditional approaches. The components of the test structure and the relationships between them are listed. The main attention is paid to the use of multiplexers and demultiplexers for controlling the processes of selection, control and output of signals. Several options for arrang-ing auxiliary hierarchical blocks and the corresponding blocks of automated formation of input actions for combinational cells are considered. A numerical assessment of the characteristics of each of the considered options is performed. A comparative analysis of the application of the proposed test structure for verifying libraries of standard digital elements in silicon is carried out. The proposed architecture was successfully applied in a test crystal for verification of three libraries of standard elements developed using the basic technology of JSC MERI CMOS 90 nm. The completeness of verification of the proposed test structure compared to the use of circuits from the ISCAS’85/89 sets is 6.19-6.31 times greater and reaches 99.94%. The area of the proposed structure is 2.29-4.65 times smaller.

This paper investigates the potential of different fermentation feedstocks towards succinic acid production. Three alternative flowsheets were constructed and modelled in SuperPro Designer™, utilizing different fermentation substrates: crude glycerol (a by-product of the biodiesel industry), a commercial 95% glucose syrup and pure glycerol. Techno-economic analysis of the modelled plants showed that all three potential investments can be economically profitable, with the crude glycerol case as the most promising one. The succinic acid production cost for the crude glycerol scenario is estimated at 3.59 $/kg, while a thorough study of the capacity effect to the economics showed that it could drop as low as $2.6 $/kg. Parametric analysis and optimization performed on a flowsheet level, indicated opportunities for lowering the production cost down to 3 $/kg, a value that could pave the framework for a further potential decrease in the selling price of the product.

Underwater source localization from a passive array of acoustic sensors is a challenging problem, especially in complex environments characterized by multipath and reverberation effects, irregular seabed geometry, and low signal-to-noise ratio. This paper proposes a recursive Bayesian approach that propagates a spectral-element approximation of the wave equation to model the discretized space-time dynamics of the acoustic field conditioned on the position of the source, and sequentially estimates the field and the position of the radiating source from the acoustic measurements. We pursue a multiple-model approach where each model assumes either the source absence or its presence within a specific spectral element. To handle the high dimension of the large-scale field estimation problem and reduce the computational complexity, the multiple-model filter is implemented by using ensemble Kalman filters. Finally, the effectiveness of the proposed multiple-model spectral-element ensemble Kalman filter is demonstrated through simulation experiments in underwater acoustic environments with regular and irregular seabed geometry and via comparison with the standard matched-field processing method.

Doğum, evlilik ve ölüm başta olmak üzere yaşamdaki önemli dönüm noktaları “geçiş dönemi” olarak adlandırılır. İnsan ve toplum için bir eşik sayılan ve temelinde “yeniden doğuş” düşüncesi bulunan bu aşamalarda, kutsal olan ile bağlantı kurularak kut alınmaya ve olumlu bir başlangıç yapılmaya çalışılmaktadır. Türkler ayrıcalıklı görülen bu zamanlarda, kökenleri arkaik düşüncelere dayanan kutlama, törenler düzenleyip ritüeller yapar. “Yeniden doğuş” düşüncesine temellenen geçiş dönemi kutlama, tören ve ritüellerine gerek biçimleri ve yapıldığı maddeler gerekse renkleri ile bu düşünceyi simgeleyen eşya ve nesneler de dahil edilmektedir. Türklerde baş renk olarak bilinen ak/beyaz renk, daima doğaya ait, saf, arınmış ve temiz olma, yücelik anlamları ile bilinmekte ve kutsal olanla ilişkilendirilmektedir. Bu nedenle özellikle doğum, evlilik ve ölüm olmak üzere geçiş dönemi kutlama, tören ve ritüellerinde ak/beyaz renkteki nesneler ve eşyalar tercih edilmekte, bunlar en önemsenen an ve durumlarda belirmektedir. Bu çalışmada ak/beyaz rengin Türk dünya görüşlerindeki yeri ve anlamı incelenecek ve bu renkteki nesne ve eşyaların geçiş dönemi ritüellerinde nasıl ve ne amaçla kullanıldığı belirlenmeye çalışılacaktır. Konuyla bağlantılı olarak Türk anlatılarının bölümlerinden ilgili örnekler verilerek, rengin Türk mitolojisinde ne şekilde yer aldığı tespit edilecektir.

ABSTRACT This study presents an alternative approach to the numerical solution of 2D electromagnetic scattering problems using a hybrid numerical technique based on a beam pattern function combined with the method of moments (MoM). A surface field distribution with finite width radiates outward, and it is used to define the new Green's function. This new Green's function has a beam aperture localized on the surface, and its beam width can be reduced to a few basis function levels by using a generalized pencil of beam function method (GPOF). This localization of the new Green's function brings to the sparsity in the main matrix. Then, the memory storage and the overall running times are reduced significantly by applying this localized radiation of Green's function. Numerical results have been presented in both polarizations for the single perfectly electrically conducting (PEC) strip geometry and 2D PEC objects with closed polygonal cross-sections such as square, triangle and arbitrary shapes.

статья основана на результатах реализации проекта «Моё село: от культурных традиций к гражданским инициативам», представляющего собой цифровое масштабирование успешной муниципальной практики музейно-культурного центра «Дом традиций» села Паракино на муниципальный уровень. Востребованность в создании проекта обусловлена динамикой и спецификой социокультурного запроса общества – «поиск себя» через растущий интерес к истории, культуре и традициям, к экологическому, рекреационному и этнографическому туризму, приводящий человека в «своё село», в родительский дом, очаг, что имеет стратегически важное значение для сохранения и развития сельских территорий, российской культуры, самобытности и суверенности.
