Incorporating Data Governance Frameworks in the Financial Industry

Data governance frameworks are critical to reducing operational costs and risks in the financial industry. Corporate data managers face challenges when implementing data governance frameworks. The purpose of this multiple case study was to explore the strategies that successful corporate data managers in some banks in the United States used to implement data governance frameworks to reduce operational costs and risks. The participants were 7 corporate data managers from 3 banks in North Carolina and New York. Servant leadership theory provided the conceptual framework for the study. Methodological triangulation involved assessment of nonconfidential bank documentation on the data governance framework, Basel Committee on Banking Supervision\u27s standard 239 compliance documents, and semistructured interview transcripts. Data were analyzed using Yin\u27s 5-step thematic data analysis technique. Five major themes emerged: leadership role in data governance frameworks to reduce risk and cost, data governance strategies and procedures, accuracy and security of data, establishment of a data office, and leadership commitment at the organizational level. The results of the study may lead to positive social change by supporting approaches to help banks maintain reliable and accurate data as well as reduce data breaches and misuse of consumer data. The availability of accurate data may enable corporate bank managers to make informed lending decisions to benefit consumers

Magnetic-time model for seed germination

Germination of seed depends on several physico-chemical factors like temperature, water potential, light,  nitrate content, smoke, electric field and magnetic field. In the present work, effect of static magnetic field on black-gram seeds (Cicer arietinum L.) was described. Seeds of C. arietinum L. were exposed in batches to static magnetic fields of 0 to 226 mT strength in steps of 50 mT (approximately) for 1 h. Treatment of seeds in these magnetic fields increased the speed of germination, seedling shoot and root length under laboratory  germination tests. On the basis of this, a new germination model called magnetic time model is developed which was incorporated in hydrothermal model and hence nominated as hydrothermal magnetic time model which is proposed to incorporate the effect of magnetic field of different intensities on plants. Magnetic time constant ΘB is determined experimentally for different seeds population. The model is helpful in a way that it defines another constant called hydrothermal-magnetic-time constant, which is of great importance to  understand the behavior of induced magnetic field on seeds and plant growth.Key words: Magnetic-time model, hydro-thermal-magnetic-time model, Cicer arietinum L

The colloidal properties of fluorocarbon emulsions

Some of the colloidal aspects of perfluorochemical emulsions have been investigated. Particular attention was given to the influence of the nature of the oil phase on emulsion stability. Bulk emulsion stability was measured by an electron micrographic technique. Interfacial and single droplet rest-time data were also collected. A range of surfactants and perfluorochemicals were investigated. It was found that emulsion stability depends on the chemical nature of the oil phase and the emulsifier. The differences in stability could be rationalized in terms of the intermolecular forces between oil molecules, and oil and surfactant molecules. The effect on stability of a small amount of an additive incorporated into the oil phase was also investigated. It is postulated that although coalescence is the main mechanism by which fluorocarbon emulsions coarsen, molecular diffusion (Ostwald Ripening), in the more stable systems, is also important. Most stable emulsions were obtained by utilizing an emulsifier system comprising a small and a large molecular weight emulsifier. Accelerated stability testing and optimum storage conditions were also investigated. About 40C was found to be the optimum storage temperature. The problem of the fluoride ion production during emulsification could be minimised by sonicating in a carbon dioxide atmosphere. The oxygen uptake and release by fluorocarbon emulsions was rapid, reaching equilibrium within half a second. The in-vitro phagocytosis experiments showed that the phagocytosis rate of fluorocarbon emulsions was dependent on the droplet diameter and its surface characteristics. Investigation of methods to sterilize the fluorocarbon emulsions showed that filtration of constituents before emulsification coupled with autoclaving had the minimum effect on stability. A qualitative correlation between single droplet stability and bulk emulsion stability was found and it is concluded that the method could be a useful screening procedure to find an optimum system

Modeling of electroluminescence in SrS:Ce ACTFEL display devices

The main objective of this study was to model electroluminescence behavior of ACTFEL display devices. Qualitative comparison of the predicted results with measurable characteristics is given. It is intended to explain certain unusual behavior that other models cannot explain fully. In particular, aspects of leading and trailing edge luminance peaks, oscillations in luminance, luminance peaks due to denting in applied voltage and multiple interfacial states are analyzed. Also, optimum concentration of activators has been analytically modeled for any phosphor to get maximum light output without causing appreciable quenching. Maximum light output for ZnS:Mn yellow devices is at about 2% Mn by weight. The beginning trailing edge peak (BTE) in SrS:Ce devices can be explained based on capture of electrons by ionized activators from the bulk traps due to their proximity. Oscillations in luminance are modeled due to distinct, widely separated and deep interfacial energy states when interface of two materials is rough. It has been observed that leading edge peak and luminance peak due to denting at leading edge are intercoupled and are partially created due to impact excitation and partially due to capture of electrons by ionized activators. Luminance vs. time graph of two interfacial energy states does not match very well with the experimental results. Luminance vs. time graph for multiple energy states matches better with experimental results

A MICROPROCESSOR-BASED SYSTEM FOR PROTECTION OF POWER TRANSFORMERS

Differential, overcurrent and ground fault relays are used for protecting transformers in electric. power systems. Several algorithms, that perform these functions and are suitable for implementation on microprocessors, have been proposed in the past. This thesis describes and evaluates an improved technique for modelling inverse-time overcurrent relay characteristics. This technique, which is used in a digital overcurrent relaying algorithm, is simple and requires a modest amount of computer memory. The proposed algorithm performs most computations in an off-line mode and, therefore, requires few on-line computations. The performance of the algorithm is evaluated using computer simulations. Some test results are reported in the thesis. Digital algorithms that can detect winding faults in power transformers are described in the thesis. The algorithms use non-linear models of a transformer to determine its health. The algorithms take the non-linearity and hysteresis of the transformer core into account, however, these do not explicitly become part of the algorithms. They are suitable for protecting transformers whose winding currents can not be measured at the terminals. The performance of the algorithms is studied for a variety of operating conditions simulated on a digital computer using the Electro-Magnetic Transient Program (EMTP). Some results of the simulation studies are reported in the thesis. The proposed algorithms for overcurrent relaying and transformer winding protection are implemented in a microprocessor-based system. The design implementation and, testing of the system are presented in the thesis. The system includes a man-machine interface for changing relay settings and relay software, and for uploading the relay signals for further analysis. The performance of the system was checked in the laboratory. The testing procedure and some test results are also presented

Fisheries education in Malaysia

The development of fisheries education in Malaysia, from its beginning in 1959, is described. There are presently three vocational schools and two institutes offering fisheries courses and six fishermen training centers. Five universities offer fisheries-related courses but only one, Universiti Pertanian Malaysia, provides degree courses in fisheries. Most employment opportunities are in government agencies. A number of areas in which improvements to the existing fisheries, educational system should be effected are discussed

Demand side management based charging strategy for fleet of plug-in hybrid electric vehicles

In coming years, the widespread use of Plug-in Hybrid Electric Vehicles (PHEVs) will impose a significant burden on the existing electric grid. The situation may worsen due to uncontrolled charging strategies adopted for PHEVs. On the other hand, these PHEVs, if charged through proper control mechanisms may reduce additional dynamic load demands. Also, if utilized properly, they may provide significant support to electric grid from time to time. The entire process of regulating the power exchanged with PHEVs w.r.t the existing grid conditions is well known as Demand Side Management (DSM). To indulge PHEVs in DSM, an accurate estimate of characteristics of PHEVs, both on-road and off-road, is necessary. Thus, this study aims to mathematically model the behaviour of four imperative parameters of PHEVs. These are dynamic travel behaviour, battery state-of-charge (SOC) requirements, the energy demands of PHEVs and, total power exchanged by PHEVs with the electric grid. In addition to this, a smart charging strategy is proposed and tested to verify the ability of PHEVs for participating in DSM for peak load management. The impacts of uncontrolled charging and smart charging of PHEVs on grid power demands are also discussed

Determination of Nanoindentation Behavior of HAZ on Glass Material Machined via ECSM Process through Simulation Approach

The current study develops a numerical model to investigate the nanoindentation behavior of heat-affected zones (HAZ) on glass material produced via the electrochemical spark machining (ECSM) method. Initially, microchannels were created using the ECSM method on soda–lime glass. Following that, a nanoindentation test was conducted to quantify the Young’s modulus and hardness of the glass sample. After that, a numerical model based on finite elements was created to characterize the changes in mechanical characteristics of HAZ. According to the findings, increasing the electrolyte concentration from 10 to 30% increases the intensity of electrochemical discharges, and thereby decreases the hardness of the work material by 16.29 to 30.58% compared to unmachined glass. The results obtained from the simulation are in close agreement with the experimental values. The maximum error obtained between simulation and experimental results is only 4.18%
