Abstract:
Stability and settlement problems are common for foundations constructed on soft soils. In major parts of the world, ground improvement techniques have been used to mitigate these challenges. This research aims to stabilize the soft soils using corex steel slag blended with terrazyme treated clay. The corex steel slag is an industrial waste formed during the extraction of steel from ores through the corex process. The corex slag of sand size in the form of columns have been used to improve the load-carrying capacity of the soft soils and to control the settlement. To increase the stiffness of the corex slag columns, the terrazyme treated clay was mixed with the corex slag. The terrazyme is an eco-friendly and sustainable organic liquid and it is fully soluble in water. To prepare the terrazyme-processed clay gel 0 to 3 % of terrazyme dissolved in water was used. Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) for terrazyme treated clay were determined through the compaction tests. Appropriate proportions of corex slag and terrazyme treated clay with a suitable curing period were obtained from unconfined compression tests. A series of laboratory model plate load tests for 3 foundation shapes were performed on soft soil, stabilized with a blend of corex slag and terrazyme treated clay. Improvement in the MDD with a reduction in OMC was noticed when terrazyme was added to soft soil. Unconfined Compressive Strength (UCS) value for corex slag increased with an increase in the content of terrazyme treated clay. Model plate load tests showed significant improvement in the load-carrying capacity of soft soil.

Abstract:
COREX and COSRI smelting reduction iron-making process could directly use coal as reductant. So it is necessary to contrast the development and technology of two kinds smelting reduction iron-making process. Due to lack of funds, COSRI smelting reduction iron-making process has not been fully developed. And the COREX has completed the transformation to the industrial production. But on the whole, COSRI has good prospects for development as COREX.

Abstract:
High CO2 emissions and energy consumption have greatly restricted the development of China’s iron and steel industry. Two alternative ironmaking processes, top gas recycling-oxygen blast furnace (TGR-OBF) and COREX®, can reduce CO2 emissions and coking coal consumption in the steel industry when compared with a conventional blast furnace (BF). To obtain parameters on the material flow of these processes, two static process models for TGR-OBF and COREX were established. Combining the operating data from the Jingtang steel plant with established static process models, this research presents a detailed analysis of the material flows, metallurgical gas generation and consumption, electricity consumption and generation, comprehensive energy consumption, and CO2 emissions of three integrated steel plants (ISP) equipped with the BF, TGR-OBF, and COREX, respectively. The results indicated that the energy consumption of an ISP with the TGR-OBF was 16% and 16.5% lower than that of a conventional ISP and an ISP with the COREX. Compared with a conventional ISP, the coking coal consumption in an ISP with the TGR-OBF and an ISP with the COREX were reduced by 39.7% and 100% respectively. With the International Energy Agency factor, the ISP with the TGR-OBF had the lowest net CO2 emissions, which were 10.8% and 35.0% lower than that of a conventional ISP and an ISP with the COREX. With the China Grid factor, the conventional ISP had the lowest net CO2 emissions—2.8% and 24.1% lower than that of an ISP with the TGR-OBF and an ISP with the COREX, respectively.

Abstract:
COREX is one of the commercialized smelting reduction ironmaking processes. It mainly includes two reactors, i.e., a (reduction) shaft furnace (SF) and a melter gasifier (MG). In comparison with the conventional blast furnace (BF), the COREX MG is not only equipped with a more complicated top charging system consisting of one gimbal distributor for coal and eight flap distributors for direct reduction iron (DRI), but also the growth mechanism of its burden pile is in a developing phase, rather than that in a fully-developed phase in a BF. Since the distribution of charged burden plays a crucial role in determining the gas flow and thus in achieving a stable operation, it is of considerable importance to investigate the burden distribution influenced by the charging system of COREX MG. In the present work, a mathematical model is developed for predicting the burden distribution in terms of burden layer structure and radial ore/coal ratio within the COREX MG. Based on the burden pile width measured in the previous physical experiments at different ring radii on a horizontal flat surface, a new growth mechanism of burden pile is proposed. The validity of the model is demonstrated by comparing the simulated burden layer structure with the corresponding results obtained by physical experiments. Furthermore, the usefulness of the mathematical model is illustrated by performing a set of simulation cases under various charging matrixes. It is hoped that the model can be used as a what-if tool in practice for the COREX operator to gain a better understanding of burden distribution in the COREX MG.

Abstract:
In COREX processes, the cold gas is produced in melter gasifier, after being cooled and dust controlled, blown into the blast furnace and used in the reduction reaction. The cold gas content plays a key role in the reaction of lump ore and pellets reduction. A prediction model of COREX cold gas content of carbon dioxide is proposed based on modified orthogonal signal correction partial least squares algorithm (MOSC-PLS). Firstly, the input and output variables of the model are selected according to the COREX processes principle. Secondly, MOSC algorithm is used to preprocess the data, in order to remove the irrelevant information between the input and output variables of the model. Finally, prediction model is built based on PLS. The real field data of cold gas content of carbon dioxide from Baosteel COREX are used for verification. The results show that MOSC-PLS has an advantage over the orthogonal signal correction partial least squares (OSC-PLS) in prediction accuracy. Thus the necessary decision supports and analysis tools for the cold gas content control are provided.

Abstract:
Slag has been used in concrete as a cementitious extender for about 50 years in South Africa. Traditionally, blastfurnace slag has been used in concrete but recently a new product called Ground Granulated Corex Slag (GGCS) has become available on the market in the Western Cape Province. The objective of this research is to characterise the properties of this new product in concrete. In this study, the properties of corex slag concrete were compared to normal blastfurnace slag and plain CEM I concretes. A series of mixes was undertaken, with water:binder ratios varying between 0.4 and 0.3, and slag replacement levels between 30 and 70%. The physical characterisation of corex slag revealed that the material is finer than blastfurnace slag, having more ultra-fine particles. The oxide analysis showed that the higher proportions of the calcium and magnesium oxides present in corex slag increase the potential for hydraulic activity of the binder compared with blastfurnace slag. The investigation of the fresh concrete properties revealed that the consistence of concrete increases with the use of slag, especially at higher water:binder ratios. Blastfurnace slag performed marginally better than corex slag. The use of slag generally increased the setting time of the paste, with pastes containing corex slag having a shorter final setting time than those containing blastfurnace slag. The setting time was also found to increase with increasing stag replacement level. The increase in setting time caused the bleed time of slag concrete to increase but the total bleed volume was significantly reduced. The bleed properties of concrete were improved when corex slag was used. It was found that the compressive strength of the new cementitious material lagged behind that of CEM I controls during early ages but after seven days, corex slag concrete showed higher strength. The strength was observed to decrease with increasing water:binder ratio. From the compressive strength results, it was deduced that the optimum corex slag substitution rate varied with water:binder ratio, ranging from 45 to 60 % The elastic modulus of corex slag concrete was found to be equal to or higher than CEM I concrete, especially at low water:binder ratios (wtb = 0.4). Deformation experiments showed that corex slag concrete had the lowest creep and shrinkage strains of all the concretes at low water:binder ratios. At higher water:binder ratios, however, the shrinkage strains were in the same range as the other two materials. Prediction models were also assessed and it was found that no model was able to accurately predict both creep and shrinkage. Generally, the shrinkage predictions were more accurate. Durability index tests showed that corex slag concrete has good to excellent potential durability, based on historical data. Marine exposure testing indicated that corex slag binds a substantial amount of chlorides, hence reducing the risk of corrosion in marine environments. Furthermore, the risk of carbonation-induced corrosion is also decreased. Expansion associated with alkali-silica reaction is minimised with the use of corex slag and the efficiency of the material increases with replacement level. It is concluded that corex slag is an excellent extender for use in concrete. Finally, recommendations are made on the need to further characterise the properties of the material.

Full text
Abstract:
Many-core architectures are more promising hardware to design real-time systems than multi-core systems as they should enable an easier mastered integration of a higher number of applications, potentially of different level of criticalities. In embedded real-time systems, these architectures will be integrated within backbone Ethernet networks, as they mostly provide Ethernet controllers as Input/Output(I/O) interfaces. Thus, a number of applications of different level of criticalities could be allocated on the Network-on-Chip (NoC) and required to communicate with sensors and actuators. However, the worst-case behavior of NoC for both inter-core and core-to-I/O communications must be established. Several NoCs targeting hard real-time systems, made of specific hardware extensions, have been designed. However, none of these extensions are currently available in commercially available NoC-based many-core architectures, that instead rely on wormhole switching with round-robin arbitration. Using this switching strategy, interference patterns can occur between direct and indirect flows on many-cores. Besides, the mapping over the NoC of both critical and non-critical applications has an impact on the network contention these core-to-I/O communications exhibit. These core-to-I/O flows (coming from the Ethernet interface of the NoC) cross two networks of different speeds: NoC and Ethernet. On the NoC, the size of allowed packets is much smaller than the size of Ethernet frames. Thus, once an Ethernet frame is transmitted over the NoC, it will be divided into many packets. When all the data corresponding to this frame are received by the DDR-SDRAM memory on the NoC, the frame is removed from the buffer of the Ethernet interface. In addition, the congestion on the NoC, due to wormhole switching, can delay these flows. Besides, the buffer in the Ethernet interface has a limited capacity. Then, this behavior may lead to a problem of dropping Ethernet frames. The idea is therefore to analyze the worst case transmission delays on the NoC and reduce the delays of the core-to-I/O flows. In this thesis, we show that the pessimism of the existing Worst-Case Traversal Time (WCTT) computing methods and the existing mapping strategies lead to drop Ethernet frames due to an internal congestion in the NoC. Thus, we demonstrate properties of such NoC-based wormhole networks to reduce the pessimism when modeling flows in contentions. Then, we propose a mapping strategy that minimizes the contention of core-to-I/O flows in order to solve this problem. We show that the WCTT values can be reduced up to 50% compared to current state-of-the-art real-time packet schedulability analysis. These results are due to the modeling of the real impact of the flows in contention in our proposed computing method. Besides, experimental results on real avionics applications show significant improvements of core-to-I/O flows transmission delays, up to 94%, without significantly impacting transmission delays of core-to-core flows. These improvements are due to our mapping strategy that allocates the applications in such a way to reduce the impact of non-critical flows on critical flows. These reductions on the WCTT of the core-to-I/O flows avoid the drop of Ethernet frames.

To ease thechoice of power efficient microcontrollers, controlled experiments were thereforeperformed with the Cortex-M4, this microcontroller was chosen because of theupgraded hardware, which has led to an appreciable change in both power- and speedefficiency compared to its predecessors.The conclusion presents important points, along with advantages and difficulties toconsider when implementing a DSP application. By comparing different optimizationswith the Floating Point Unit(FPU), Fixed-point and software Floating-point, the resultsshow that there are major differences in power consumption between these threeoptions. Depending on which option and optimization used then the powerconsumption can exceed over 70% more compared to the other options available.

Abstract:
Deposition of silica shells onto ZnO nanoparticles (NPs) in dimethyl sulfoxide was found to be an efficient tool for terminating the growth of ZnO NPs during thermal treatment and producing stable core–shell ZnO NPs with core sizes of 3.5–5.8 nm. The core–shell ZnO–SiO2 NPs emit two photoluminescence (PL) bands centred at [similar]370 and [similar]550 nm originating from the direct radiative electron–hole recombination and defect-mediated electron–hole recombination, respectively. An increase of the ZnO NP size from 3.5 to 5.8 nm is accompanied by a decrease of the intensity of the defect PL band and growth of its radiative life-time from 0.78 to 1.49 μs. FTIR spectroscopy reveals no size dependence of the FTIR-active spectral features of ZnO–SiO2 NPs in the ZnO core size range of 3.5–5.8 nm, while in the Raman spectra a shift of the LO frequency from 577 cm−1 for the 3.5 nm ZnO core to 573 cm−1 for the 5.8 nm core is observed, which can indicate a larger compressive stress in smaller ZnO cores induced by the SiO2 shell. Simultaneous hydrolysis of zinc(II) acetate and tetraethyl orthosilicate also results in the formation of ZnO–SiO2 NPs with the ZnO core size varying from 3.1 to 3.8 nm. However, unlike the case of the SiO2 shell deposition onto the pre-formed ZnO NPs, individual core–shell NPs are not formed but loosely aggregated constellations of ZnO–SiO2 NPs with a size of 20–30 nm are. The variation of the synthetic procedures in the latter method proposed here allows the size of both the ZnO core and SiO2 host particles to be tuned<br>Dieser Beitrag ist aufgrund einer (DFG-geförderten) Allianz- bzw.

Abstract:
Dopamine is implicated in the responsiveness to rewarding properties of natural and pharmacological stimuli. Conditioned stimuli (CS), linked to rewards such as food or drugs of abuse (uncontidioned stimuli, US), are essential to support the motivated behaviour. The role of mesocortical and mesolimbic DA in response to food CS after instrumental paradigm still remains unclear. The aim of our study was to investigate by microdialysis the impact of instrumental food CSs and US on behaviour and on basal DA in three terminal DA areas: shell and core of nucleus accumbens (NAc) and medial prefrontal cortex (mPFCX), using a food self-administration paradigm. Rats were trained to acquire sucrose self-administration under a Fixed Ratio 1 (FR 1) or FR5 variable time out schedule of responding. After training, animals were able to self-administer sucrose pellets and microdialysis coupled with self-administration experiments were performed.. The main finding of our study was that NAc shell DA has been activated not only by the conditioned cues but also by food after the instrumental conditioning. When both stimuli are presented in the same moment the increase of DA is strengthened and prolonged. DA response was obtained in NAc core only during US presentation. mPFCX has been activated by each component of motivated behaviour, except for the response to CS using a FR5 schedule. We can conclude that DA in the NAc shell plays an important role on the acquisition and expression of motivated behaviour in food consumption, whereas NAc core and PFCX are less implicated. This study provides a robust and reproducible model for a parametric study of the relationship between behaviour and DA transmission in the NAc shell and core and in the mPFCX .

Abstract:
A new whole-core transport method is described for 3-D hexagonal geometry. This is an extension of a stochastic-deterministic hybrid method which has previously been shown highly accurate and efficient for eigenvalue problems. Via Monte Carlo, it determines the solution to the transport equation in sub-regions of reactor cores, such as individual fuel elements or sections thereof, and uses those solutions to compose a library of response expansion coefficients. The information acquired allows the deterministic solution procedure to arrive at the whole core solution for the eigenvalue and the explicit fuel pin fission density distribution more quickly than other transport methods. Because it solves the transport equation stochastically, complicated geometry may be modeled exactly and therefore heterogeneity even at the most detailed level does not challenge the method. In this dissertation, the method is evaluated using comparisons with full core Monte Carlo reference solutions of benchmark problems based on gas-cooled, graphite-moderated reactor core designs. Solutions are given for core eigenvalue problems, the calculation of fuel pin fission densities throughout the core, and the determination of incremental control rod worth. Using a single processor, results are found in minutes for small cores, and in no more than a few hours for a realistically large core. Typical eigenvalues calculated by the method differ from reference solutions by less than 0.1%, and pin fission density calculations have average accuracy of well within 1%, even for unrealistically challenging core configuration problems. This new method enables the accurate determination of core eigenvalues and flux shapes in hexagonal cores with efficiency far exceeding that of other transport methods.

Abstract:
The Corex process is a more environmental-friendly method of pig iron production than the blast-furnace process. Additionally, this technology is accompanied by production of a fuel gas with a LHV twice as high as blast-furnace gas. Corex gas may be a useful fuel in a metallurgical CHP plant including a combined gas-and-steam cycle. The utilization of Corex gas contributes also to a decrease of CO2 emissions, which is an advantage from the viewpoint of the greenhouse effect. Moreover removing CO2 from the gas before its consumption can allow a further reduction of greenhouse issues. The paper considers the application of two methods of CO2 removal, namely “physical absorption (Selexol solvent)” and “cryogenic gas separation”. The effect of CO2 removal on the operation of CHP plants has been investigated. The removal of CO2 affects first of all the quality of fuel gas in comparison with the raw Corex gas. However, the CO2-removal installation is characterized by a considerable power consumption. Thus the net power and the efficiency of the CHP plant are reduced. Comparing the two considered methods of CO2 removal the cryogenic separation method requires more input energy, but in some cases liquefied CO2 may be an attractive agent. The paper contains the results of a quantitative analysis of the application of these two CO2-removal methods in the Corex technology and their effect on the exploitation characteristics of CHP plants fired with Corex gas.

Full text
Abstract:
Learning by children and animals occurs effortlessly and largely without obvious supervision. Successes in automating supervised learning have not translated to the more ambiguous realm of unsupervised learning where goals and labels are not provided. Barlow (1961) suggested that the signal that brains leverage for unsupervised learning is dependence, or redundancy, in the sensory environment. Dependence can be characterized using the information-theoretic multivariate mutual information measure called total correlation. The principle of Total Cor-relation Ex-planation (CorEx) is to learn representations of data that "explain" as much dependence in the data as possible. We review some manifestations of this principle along with successes in unsupervised learning problems across diverse domains including human behavior, biology, and language.

Full text
Abstract:
As of September 2009, GE Energy (GE) has successfully expanded its large-frame gas turbine product line to burn ultra-low calorific steel mill gas fuel blends, especially mixtures of Blast Furnace Gas (BFG) and Coke Oven Gas (COG). The first two GE frame 9E Gas Turbines in China with this capability have thus far accumulated more than 8000 hours operating on BFG/COG blends. The China site comprises two complete power trains, including GE 9E gas turbines, generators, fuel cleaning equipment, and fuel gas compressors. Since startup, combustion operating parameters have remained within design limits, consistent with the extensive full-scale lab testing GE conducted during the turbine’s design development effort, and comparable to fleet experience on natural gas fired GE gas turbines. Based on this accumulated data set, especially the wide range of gas compositions tested in the combustion lab, similar process gases such as corex and finex gases, and air-blown synthetic gases are operable in this system. The GE 9E platform targets the 50Hz market. For 60Hz applications, a 7EA BFG product is available.

Full text
Abstract:
Each year, more than 17,000 gas storage wells in the United States lose from 3�5% of their storage capacity and deliverability. In addition, the gas storage industry spends $80�100 million annually to revitalize existing wells; thus, there is an economic incentive to develop new stimulation methods. Limited laboratory information suggests that using surfactants to alter the wettability of the reservoir rock could increase deliverability of gas storage wells. The objective of this project was to develop new technology to improve deliverability from gas storage wells. Two cost-effective surfactants were selected from 11 candidates through preliminary screening tests for additional reservoir core tests. Reservoir cores from three gas storage facilities including sandstone and dolomite reservoirs were used to evaluate surfactant-gas-core systems. The imbibition and core flood tests showed that gas deliverability and storage capacity were improved in surfactant-treated sandstone cores. However, the surfactants had a very limited effect on dolomite cores. An engineering analysis was conducted to develop an analytical method to evaluate future field tests of the new technology. The aquifer storage facilities are candidates for field testing.

Full text
Abstract:
In water-wet gas storage reservoirs, the imbibition force promotes the retention of water in the pore space, which curtails the deliverability of gas to the wellbore during periods of high demand. Similarly, the injection of gas during the fill cycle is restricted. In addition, the pore space occupied by irreducible water is not available to hold gas. The objective of this Phase II project was to demonstrate in the field the new technology developed in the laboratory during Phase I. Wettability alteration was evaluated as a technique to improve gas deliverability from gas storage wells during Phase I. During the first year, two cost-effective surfactants were selected from 11 candidates through various laboratory screening and reservoir core tests. Reservoir cores from three gas storage facilities including sandstone and dolomite reservoirs were used to evaluate the two surfactants. The imbibition and core flood tests showed that gas deliverability and storage capacity were improved in surfactant-treated sandstone cores. However, these surfactants had a very limited effect on dolomite cores. An engineering analysis was conducted to develop an analytical method for evaluating future field tests of the new technology. It was concluded that the aquifer storage facilities are candidates for field testing. Results from Phase I provided the foundation for this Phase II project.

Brooks, G. R. Thickness record of varves from glacial Ojibway Lake recovered in sediment cores from Frederick House Lake, northeastern Ontario. Natural Resources Canada/CMSS/Information Management, 2022. http://dx.doi.org/10.4095/329275.

Full text
Abstract:
The thicknesses of 384 rhythmic couplets were measured along a composite sequence of glacial Lake Ojibway glaciolacustrine deposits recovered in two sediment cores from Frederick House Lake, Ontario. The visual comparison of distinctive couplets in the CT-scan radiographs of the Frederick House core samples to photographs of core samples from Reid Lake show a match of ±1 varve number from v1656-v1902, and ±5 varve numbers between v1903-v2010, relative to the regional numbering of the Timiskaming varve series. There are two interpretations for the post-v2010 couplets that fall within the Connaught varve sequence of the regional series. In the first, the interpreted numbering spans from v2066-v2115, which produces a gap of 55 missing varves equivalent to v2011-v2065, and corresponds to the original interpretation of the Connaught varve numbering. The second spans v2011a-v2060a, and represents alternative (a) numbering for the same varves. Varve thickness data are listed in spreadsheet files (.xlsx and .csv formats), and CT-Scan radiograph images of core samples are laid out on a mosaic poster showing the interpreted varve numbering and between-core sample correlations of the varve couplets.

Full text
Abstract:
This short note describes one way of taking advantage of the multiple cores on most desktop computers. It describes running one of the processes in the GTAP build procedure called ’FIT’. The input to ’FIT’ is a balanced input-output table (IOT), which is adjusted to a number of exogenous elements including aggregate domestic absorption and import and export vectors. It is run for each of the countries/regions in the build, but there is no interaction across countries/regions and thus can be run in parallel. The procedure uses a Python script to run the ’FIT’ procedure, either sequentially or in parallel. Most of the code is generic and thus it can be easily adapted to other programs that can take advantage of parallelism, for example Monte Carlo simulations. For the tested ’FIT’ procedure, it reduces the runtime from 75 minutes to 14 minutes on a relatively new desktop with a 12th Generation Intel Core I-9 CPU with 16 physical cores.
