Assessing Ukrainian Banking Performance Before and After the Crisis

The main goal of this paper is to analyze the impact of the 2008 global financial crisis on the Ukrainian financial system, and on Ukrainian bank performance. Our analysis is based on key bank performance indicators from 2003-2011. Bank assets, liabilities and capital are analyzed, and changes in bank management are taken into consideration. Special attention is paid to changes in bank stock prices of two of the largest banks, following the crisis.performance, problem loans, debt provision, banking system, financial crisis, bank stock prices

The Case for Financial Sector Liberalization in Ethiopia

This paper focuses on issues of financial sector liberalization in Ethiopia, with reference in particular to the Ethiopian banking sector. We identify two factors that may constrain Ethiopia’s financial development. One is the closed nature of the Ethiopian financial sector in which there are no foreign banks, a non-competitive market structure, and strong capital controls in place. The other is the dominant role of state-owned banks. Our observations suggest that the Ethiopian economy would benefit from financial sector liberalization, especially from the entry of foreign banks and the associated privatization of state-owned banks.foreign banks, state-owned banks, financial sector liberalization, Africa, Ethiopia

A 3-D model for the CD40 ligand predicts that it is a compact trimer similar to the tumor necrosis factors

Based on the similarity in primary structure between the newly characterized ligand for CD40 (CD40L) and the tumor necrosis factors (TNFs), we have modeled a detailed 3-D structure for CD40L. We used the known structure of TNFα as a template for the generation of the CD40L model. The soundness of the model-building algorithms was verified by constructing a 3-D model of TNFβ and comparing it to its crystallographically determined structure. The CD40L sequence is entirety compatible with the ‘Jelly-roll' β-strand structure characteristic of the TNFs. Like the TNFs, CD40L is predicted to form a compact trimer, although the interactions between monomers are distinct from those found in the TNFs. The model predicts which regions of CD40L could interact with its receptor(s) and which amino acids are essential for the maintenance of its trimeric structur

Physics of prestall propagating disturbances in axial compressors and their potential as a stall warning indicator

Axial compressors in aero engines are prone to suffering a breakdown of orderly flow when operating at the peak of the pressure rise characteristic. The damaging potential of separated flows is why a safe distance has to be left between every possible operating point and an operating point at which stall occurs. During earlier investigations of stall inception mechanisms, a new type of prestall instability has been found. In this study, it could be demonstrated that the prestall instability characterised by discrete flow disturbances can be clearly assigned to the subject of “Rotating Instabilities”. Propagating disturbances are responsible for the rise in blade passing irregularity. If the mass flow is reduced successively, the level of irregularity increases until the prestall condition devolves into rotating stall. The primary objective of the current work is to highlight the basic physics behind these prestall disturbances by complementary experimental and numerical investigations. Before reaching the peak of the pressure rise characteristic flow, disturbances appear as small vortex tubes with one end attached to the casing and the other attached to the suction surface of the rotor blade. These vortex structures arise when the entire tip region is affected by blockage and at the same time the critical rotor incidence is not exceeded in this flow regime. Furthermore, a new stall indicator was developed by applying statistical methods to the unsteady pressure signal measured over the rotor blade tips, thus granting a better control of the safety margin.DFG, 325093850, Open Access Publizieren 2017 - 2018 / Technische Universität Berli

Experimental investigation of a turbine sealing cavity exposed to free stream pressure fluctuation

The current investigation examines the impact of a new pulsed unsteady combustion to the turbine sealing cavity, which prevents hot gas ingestion into the inner machine. Sealing flow is ensured by relatively cold secondary air blowing radially through the rotor-stator-wheel space. The interaction between the sealing flow and the main gas flow however causes aerodynamic losses. These losses as well as the secondary compressor air should be kept at a minimum in order to increase the efficiency of the whole machine. The Hot-Acoustic-Testrig (HAT) allows an investigation of the subject under realistic flow conditions. Therefore a specific measurement section has been designed, which features a plenum to provide secondary air to the main flow. To simulate an pressure increasing combustion, a setup with 6 fast shifting valves was realized. The unsteady flow was measured by pressure tabs with a high time resolution. In the next step a characteristic linear cascade was designed to replace the turbine stator and generate a typical stator wake. Measurements of the total pressure loss over the cascade vanes have been conducted by means of a five-hole probe and by Particle Image Velocimetry. A considerable pressure loss inside the vane wake was observed at a Mach number Ma = 0.35. The nvestigation is a subproject of the Collaborative Research Center 1029 Substantial efficiency increase in gas turbines through direct use of coupled unsteady combustion and flow dynamics and gives an outlook to further steps.DFG, 200291049, SFB 1029: TurbIn - Signifikante Wirkungsgradsteigerung durch gezielte, interagierende Verbrennungs- und Strömungsinstationaritäten in Gasturbine

Detailed design of a high speed switched reluctance starter/generator for more/all electric aircraft

The basic concepts and advantages of more/all electric aircraft (M/AEA) are briefly addressed. The combined starter/generator (CS/G) system is introduced as a key technology to enable M/AEA. Some important performance requirements for CS/G system are obtained. Based on these requirements, a high speed switched reluctance machine (SRM) is designed to operate as a starter/generator. The entire design process is mainly divided into two stages: electromagnetic design and thermal design. In electromagnetic design stage, the electromagnetic structure and dimensions of the machine and the number of phase winding turns per pole are obtained; the topology and main technical details of the converter are briefly introduced as well. In thermal design stage, a liquid-cooling system is designed based on the thermal analysis of the machine. In the end, the performances of the designed SRM are basically verified by simulation. To get high performances, the exciting angles are optimized in two different operating modes respectively, and the optimized performances in the motoring mode are given as well

SWISS-MODEL: an automated protein homology-modeling server

SWISS-MODEL (http://swissmodel.expasy.org) is a server for automated comparative modeling of three-dimensional (3D) protein structures. It pioneered the field of automated modeling starting in 1993 and is the most widely-used free web-based automated modeling facility today. In 2002 the server computed 120 000 user requests for 3D protein models. SWISS-MODEL provides several levels of user interaction through its World Wide Web interface: in the ‘first approach mode' only an amino acid sequence of a protein is submitted to build a 3D model. Template selection, alignment and model building are done completely automated by the server. In the ‘alignment mode', the modeling process is based on a user-defined target-template alignment. Complex modeling tasks can be handled with the ‘project mode' using DeepView (Swiss-PdbViewer), an integrated sequence-to-structure workbench. All models are sent back via email with a detailed modeling report. WhatCheck analyses and ANOLEA evaluations are provided optionally. The reliability of SWISS-MODEL is continuously evaluated in the EVA-CM project. The SWISS-MODEL server is under constant development to improve the successful implementation of expert knowledge into an easy-to-use serve
