Performance Evaluation of Sugar Cane Milling Plant and Optimization of Process Parameters: A Case of Wonji-Shoa Sugar Factory
Creators: name: Mesele, Bocha
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Performance assessment of WSSF and setting targets for the relatively inefficient mills to improve the efficiency and productivity is crucial. This study, focus on performance evaluation of milling plant and optimization of its process parameters. The milling plant (WSSF) performances have been evaluated in terms of its Brix juice extracted at all mill sets (5 sets). The performance of each mill was monitored by drawing juice Brix curves. From the Brix curve, the second mill front roller Brix curve overlays the back roller Brix curve this was not appropriate hence, improvement for delivery mill setting was desired. However, the reverse curve showed acceptable result. The juice and bagasse sample analysis for each mill set were analyzed then maximum loss areas were identified and the process optimization were done. The Brix free water for WSSF were done and found to be averagely 30.63 % on cane fiber. The statistical analysis were done by design expert software (6.08, version) of central composite design. The study were done by varying the effect of hydraulic pressure and imbibition water flow on the last mill for the response variables of pol and moisture % of final bagasse. The experimental design combination were held by inserting the lowest and highest values of hydraulic pressure and quantity of imbibition water flow rate for the last mill. The optimal results of pol and moisture % of bagasse were between 1.63 - 1.88% and 50.47 - 51.31% respectively, with the respective hydraulic pressure and quantity of imbibition water application of 195 - 200 kg/cm 2 3 and 71.3 - 72 m /hr. The pol and Brix extraction trends were done for how each and individual mills can perform well for a given milling season. The existing milling plant flow diagram were modified by recycling the primary juice Cush-Cush prior to the first mill and secondary juice Cush-Cush to the second mill. Using the optimum values of application of hydraulic pressure and quantity of imbibition water flow rate on the last mill, drawing juice Brix curve, Brix free water on cane fiber and recycling of respective Cush – Cush to recommended point and the optimum output of pol and moisture content of last mill bagasse which can be taken as a positive outcome to bring efficiency improvement, product maximization, for energy saving, cost reduction and increased profitability to WSSF in particular and all other sugar factories as general.

description: There is clearly an urgent need for representative animal models in the investigation of atherosclerotic plaque rupture. The primary aim of this study is therefore to generate an animal model which will further the understanding of the mechanism involved in the process of plaque rupture and aid in the development of new therapeutic agents (Chapter 2). The second aim of this study is to develop a non-invasive diagnostic tool for atherosclerosis. We hypothesized that coronary artery disease is reflected in a specific urine polypeptide pattern that originates from proteins present in atherosclerotic plaque (Chapter 4). Thirdly, ApoE-deficient mice provide a controllable pattern of atherosclerosis in experimental conditions. We would like to apply urine proteomic analysis to identify novel biomarkers of atherosclerotic disease (Chapter 3). Fourthly, it is well-known that CRP is associated with cardiovascular risks. Chapter 5 will highlight the divergent effect of monomeric CRP in comparison to pentameric CRP on atherosclerosis. Overall, this thesis will focus on the following objectives: Chapter 2: Creation of a mouse model reflecting human vulnerable plaque rupture (Paper submitted). Chapter 3: Urine Proteome analysis reflects atherosclerotic disease in an ApoE-/- mouse model and allows the discovery of new biomarkers and mediators of atherosclerosis (Paper submitted). Chapter 4: Evaluation of urine proteome pattern analysis for its potential to reflect coronary artery atherosclerosis in symptomatic patients (Paper published). Chapter 5: Dissociation of pentameric to monomeric C-reactive protein on activated platelets localizes inflammation to atherosclerotic plaques (Paper published).

description: We study whether dry merger-driven size growth of massive elliptical galaxies depends on their initial structural concentration, and analyse the validity of the homology hypothesis for virial mass determination in massive ellipticals grown by dry mergers. High-resolution simulations of a few realistic merger trees, starting with compact progenitors of different structural concentrations (Sérsic indices n), show that galaxy growth has little dependence on the initial Sérsic index (larger n leads to slightly larger size growth), and depends more on other particulars of the merger history. We show that the deposition of accreted matter in the outer parts leads to a systematic and predictable breaking of the homology between remnants and progenitors, which we characterize through the evolution, during the course of the merger history, of virial coefficients K = GM/Re σ^2 associated to the most commonly-used dynamical and stellar mass parameters. The virial coefficient for the luminous mass, K , is about 50 per cent larger at the z = 2 start of the merger evolution than in z = 0 remnants. Ignoring virial evolution leads to biased virial mass estimates. We provide K corresponding to a variety of dynamical and stellar mass parameters, and provide recipes for the dynamical determination of galaxy masses. For massive, non-compact ellipticals, the popular expression M = 5 Re σ^2 / G underestimates the dynamical mass within the luminous body by factors of up to 4; it instead provides an approximation to the total stellar mass with smaller uncertainty than current stellar population models.

description: Hot Jupiters are the most studied and easily detectable exoplanets for transit observations.However, the correlation between the atmospheric flow and the emission spectra of such planets is still not understood. Due to huge day-night temperature contrast in hot Jupiter, the thermal redistribution through atmospheric circulation has a significant impact on the vertical temperature-pressure structure and on the emission spectra. In the present work, we aim to study the variation of the temperature-pressure profiles and the emission spectra of such planets due to different amounts of atmospheric heat redistribution. For this purpose, we first derive an analytical relation between the heat redistribution parameter f and the emitted flux from the uppermost atmospheric layers of hot Jupiter. We adopt the three possible values of f under isotropic approximation as 1/4, 1/2, and 2/3 for full-redistribution, semi-redistribution and no-redistribution cases respectively and calculate the corresponding temperature-pressure profiles and the emission spectra. Next, we model the emission spectra for different values of f by numerically solving the radiative transfer equations using the discrete space theory formalism. We demonstrate that the atmospheric temperature-pressure profiles and the emission spectra both are susceptible to the values of the heat redistribution function. A reduction in the heat redistribution yields a thermal inversion in the temperature-pressure profiles and hence increases the amount of emission flux. Finally, we revisits the hot Jupiter XO-1b temperature-pressure profile degeneracy case and show that a non-inversion temperature-pressure profile best explains this observed planetary dayside emission spectra.

description: We present the Spectroscopic Classification of Astronomical Transients (SCAT) survey, which is dedicated to spectrophotometric observations of transient objects such as supernovae and tidal disruption events. SCAT uses the SuperNova Integral-Field Spectrograph (SNIFS) on the University of Hawai'i 2.2-meter (UH2.2m) telescope. SNIFS was designed specifically for accurate transient spectrophotometry, including absolute flux calibration and host-galaxy removal. We describe the data reduction and calibration pipeline including spectral extraction, telluric correction, atmospheric characterization, nightly photometricity, and spectrophotometric precision. We achieve $\lesssim 5\%$ spectrophotometry across the full optical wavelength range ($3500-9000~Å$) under photometric conditions. The inclusion of photometry from the SNIFS multi-filter mosaic imager allows for decent spectrophotometric calibration ($10-20\%$) even under unfavorable weather/atmospheric conditions. SCAT obtained $\approx 640$ spectra of transients over the first 3 years of operations, including supernovae of all types, active galactic nuclei, cataclysmic variables, and rare transients such as superluminous supernovae and tidal disruption events. These observations will provide the community with benchmark spectrophotometry to constrain the next generation of hydrodynamic and radiative transfer models.

description: Chimera-like states are manifested through the coexistence of synchronous and asynchronous dynamics and have been observed in various systems. To analyze the role of network topology in giving rise to chimera-like states we study a heterogeneous network model comprising two group of nodes, of high and low degrees of connectivity. The architecture facilitates the analysis of the system, which separates into a densely-connected coherent group of nodes, perturbed by their sparsely-connected drifting neighbors. It describes a synchronous behavior of the densely-connected group and scaling properties of the induced perturbations.
A decomposition framework for visualising telecommunications and cyberspace systems

description: A new technique has been developed to visualise massive amounts of telecommunications and network data. This is achieved by representing the discrete data in the form of a continuous surface map similar to meteorological weather maps to enable local and large scale features or behaviours to be viewed and analysed. The technique has two steps: (1) The discrete data is interpreted as a set of vectors positioned on a geographical map; (2) The set of vectors are transformed into a 3 dimensional surface called a torque surface. The transformation utilises the notion of physical torque defined by vector cross product. The torque affect is modified by a gaussian function whose parameter when varied, reveals local and global features on the torque surface. In the definitive version, surface peaks represent the source of data output. Peak heights represent the volume of output. Nadirs which are valleys surrounding peaks, indicate direction of output. Nadir depths represent directional output in relation to peaks. The torque surface is shown to be a Lipschitz function which can be encoded into binary sequences using a proven efficient technique from the global optimisation discipline. Lipschitz functions are represented by monotone functions by applying a symmetric chain decomposition on an E grid. These binary sequences effectively reduce the data representation to a size that can be managed by a desktop computer. The peaks and nadirs surface can be viewed as a "meteorological weather" map of telecommunications or cyberspace data. The geographical context of the data is clearly seen as in a weather map. In particular, the shape of the surface gives large-scale information similar to a weather map such as the position and motion of a front. The weather map view allows an unlimited amount of data to be viewed in a limited area such as on a computer monitor. The evolution of a network can be visualised in an animation of a series of torque surface "snapshots" of a network taken at regular time intervals.

description: A nonlinear electronic circuit comprising of three nodes with a feedback loop is analyzed. The system has two stable states, a uniform state and a sinusoidal oscillating state, and it transitions from one to another by means of a Hopf bifurcation. The stability of this system is analyzed with nonlinear equations derived from a repressilator-like transistor circuit. The apparatus is simple and inexpensive, and the experiment demonstrates aspects of nonlinear dynamical systems in an advanced undergraduate laboratory setting.

description: A comprehensive summary of the measurements made to characterize test mass charging due to the space environment during the LISA Pathfinder mission is presented. Measurements of the residual charge of the test mass after release by the grabbing and positioning mechanism, show that the initial charge of the test masses was negative after all releases, leaving the test mass with a potential in the range $-12$ mV to $-512$ mV. Variations in the neutral test mass charging rate between $21.7$ e s$^{-1}$ and $30.7$ e s$^{-1}$ were observed over the course of the 17-month science operations produced by cosmic ray flux changes including a Forbush decrease associated with a small solar energetic particle event. A dependence of the cosmic ray charging rate on the test mass potential between $-30.2$ e s$^{-1}$ V$^{-1}$ and $-40.3$ e s$^{-1}$ V$^{-1}$ was observed and this is attributed to a contribution to charging from low-energy electrons emitted from the gold surfaces of the gravitational reference sensor. Data from the on-board particle detector show a reliable correlation with the charging rate and with other environmental monitors of the cosmic ray flux. This correlation is exploited to extrapolate test mass charging rates to a 20-year period giving useful insight into the expected range of charging rate that may be observed in the LISA mission.

description: Total intensity variability light curves offer a unique insight into the ongoing debate about the launching mechanism of jets. For this work, we utilise the availability of radio and $γ$-ray light curves over a few decades of the radio source 3C 84 (NGC 1275). We calculate the multiband time lags between the flares identified in the light curves via discrete cross-correlation and Gaussian process regression. We find that the jet particle and magnetic field energy densities are in equipartition ($k_\textrm{r} = 1.08\pm0.18$). The jet apex is located $z_\textrm{91.5 GHz}= 22 - 645$ $R_\textrm{s}$ ($2 - 20 \times 10^{-3}$ pc) upstream of the 3 mm radio core; at that position, the magnetic field amplitude is $B_\textrm{core}^\textrm{91.5 GHz}= 3 - 10$ G. Our results are in good agreement with earlier studies, which utilised very-long-baseline interferometry. Furthermore, we investigate the temporal relation between the ejection of radio and $γ$-ray flares. Our results are in favour of the $γ$-ray emission being associated with the radio emission. We are able to tentatively connect the ejection of features identified at 43 and 86 GHz to prominent $γ$-ray flares. Finally, we compute the multiplicity parameter $λ$ and the Michel magnetisation $σ_\textrm{M}$ and find that they are consistent with a jet launched by the Blandford & Znajek 1977 mechanism.

description: Iron sulfate has a diversified uses in agriculture, chemical industries and waste water treatment plants. Although Ethiopia has a huge deposits of iron ore. Therefore, this study investigates the potential of the country to produce iron sulfate from local iron ore and sulfuric acid. Iron samples has been taken from two ores namely Horu Guduru and Melkasedi in Oromia regional state characterized, 77% and 66% weight based iron oxide composition obtained from Horu Guduru and Melkasedi respectively. The sample from high iron oxide composition ore, Horu Guduru was reacted with sulfuric acid and hydro chloric acid subsequently by varying three process variables: temperature, reaction time and particle size. From the analysis the optimum iron sulfate yield obtained is 97.75% at temperature of (75oC), reaction time 60 min and particle size 1.00(which is <0.125mm) . Lastly, after iron sulfate characterization its production economics evaluated. The total investment cost of the project is estimated to be 1,830,822 birr. The project is financially viable with an internal rate of return (IRR) of 17.68 % and a Net annual profit of Birr 6,144,677.5birr/yr, at discounted rate of 10%. From the result, it is possible to conclude that establishment of such factory in the country saves foreign exchange, contributes for the economy, creates job opportunities, assures product availability and enhances input and output chain in the country

description: Entity Alignment (EA) aims to match equivalent entities that refer to the same real-world objects and is a key step for Knowledge Graph (KG) fusion. Most neural EA models cannot be applied to large-scale real-life KGs due to their excessive consumption of GPU memory and time. One promising solution is to divide a large EA task into several subtasks such that each subtask only needs to match two small subgraphs of the original KGs. However, it is challenging to divide the EA task without losing effectiveness. Existing methods display low coverage of potential mappings, insufficient evidence in context graphs, and largely differing subtask sizes. In this work, we design the DivEA framework for large-scale EA with high-quality task division. To include in the EA subtasks a high proportion of the potential mappings originally present in the large EA task, we devise a counterpart discovery method that exploits the locality principle of the EA task and the power of trained EA models. Unique to our counterpart discovery method is the explicit modelling of the chance of a potential mapping. We also introduce an evidence passing mechanism to quantify the informativeness of context entities and find the most informative context graphs with flexible control of the subtask size. Extensive experiments show that DivEA achieves higher EA performance than alternative state-of-the-art solutions.

description: We study patterns of quantum entanglement in systems of spins and ghost-spins regarding them as simple quantum mechanical toy models for theories containing negative norm states. We define a single ghost-spin as in arXiv:1602.06505 [hep-th] as a 2-state spin variable with an indefinite inner product in the state space. We find that whenever the spin sector is disentangled from the ghost-spin sector (both of which could be entangled within themselves), the reduced density matrix obtained by tracing over all the ghost-spins gives rise to positive entanglement entropy for positive norm states, while negative norm states have an entanglement entropy with a negative real part and a constant imaginary part. However when the spins are entangled with the ghost-spins, there are new entanglement patterns in general. For systems where the number of ghost-spins is even, it is possible to find subsectors of the Hilbert space where positive norm states always lead to positive entanglement entropy after tracing over the ghost-spins. With an odd number of ghost-spins however, we find that there always exist positive norm states with negative real part for entanglement entropy after tracing over the ghost-spins.

description: A model is presented that explains the charging rate of the LISA Pathfinder test masses by the interplanetary cosmic ray environment. The model incorporates particle-tracking from TeV to eV energies using a combination of GEANT4 and a custom low-energy particle generation and tracking code. The electrostatic environment of the test mass is simulated allowing for a comparison of the test-mass charging-rate dependence on local electric fields with observations made in orbit. The model is able to reproduce the observed charging behavior with good accuracy using gold surface properties compatible with literature values. The results of the model confirm that a significant fraction of the net charging current is caused by a population of low-energy ($\sim$eV) electrons produced by electron- and ion-induced kinetic emission from the test mass and surrounding metal surfaces. Assuming a gold work function of 4.2 eV, the unbalanced flow of these electrons to and from the unbiased test mass contributes $\sim$10% of the overall test mass charging rate. Their contribution to the charging-current shot noise is disproportionately higher and it adds $\sim$40% to the overall predicted noise. However, even with this increased noise contribution the overall charging-current noise is still only 40% of that measured in-orbit, and this remains an unsolved issue.

description: Nanophotonics focuses on the control of light and the interaction with matter by the aid of intricate nanostructures. Typically, a photonic nanostructure is carefully designed for a specific application and any imperfections may reduce its performance, i.e., a thorough investigation of the role of unavoidable fabrication imperfections is essential for any application. However, another approach to nanophotonic applications exists where fabrication disorder is used to induce functionalities by enhancing light-matter interaction. Disorder leads to multiple scattering of light, which is the realm of statistical optics where light propagation requires a statistical description. We review here the recent progress on disordered photonic nanostructures and the potential implications for quantum photonics devices.

description: While two-way relaying is a promising way to enhance the spectral efficiency of wireless networks, the imbalance of relay-user distances may lead to excessive wireless power at the nearby-users. To exploit the excessive power, the recently proposed harvest-then-transmit technique can be applied. However, it is well-known that harvest-then-transmit introduces uplink-downlink coupling for a user. Together with the co-dependent relationship between paired users and interference among multiple user pairs, wirelessly powered two-way relay network suffers from the unique pairwise uplink-downlink coupling, and the joint uplink-downlink network design is nontrivial. To this end, for the one pair users case, we show that a global optimal solution can be obtained. For the general case of multi-pair users, based on the rank-constrained difference of convex program, a convergence guaranteed iterative algorithm with an efficient initialization is proposed. Furthermore, a lower bound to the performance of the optimal solution is derived by introducing virtual receivers at relay. Numerical results on total transmit power show that the proposed algorithm achieves a transmit power value close to the lower bound.

description: We present KETJU, a new extension of the widely-used smoothed particle hydrodynamics simulation code GADGET-3. The key feature of the code is the inclusion of algorithmically regularized regions around every supermassive black hole (SMBH). This allows for simultaneously following global galactic-scale dynamical and astrophysical processes, while solving the dynamics of SMBHs, SMBH binaries and surrounding stellar systems at sub-parsec scales. The KETJU code includes Post-Newtonian terms in the equations of motions of the SMBHs which enables a new SMBH merger criterion based on the gravitational wave coalescence timescale pushing the merger separation of SMBHs down to $\sim 0.005$ pc. We test the performance of our code by comparison to NBODY7 and rVINE. We set up dynamically stable multi-component merger progenitor galaxies to study the SMBH binary evolution during galaxy mergers. In our simulation sample the SMBH binaries do not suffer from the final-parsec problem, which we attribute to the non-spherical shape of the merger remnants. For bulge-only models, the hardening rate decreases with increasing resolution, whereas for models which in addition include massive dark matter halos the SMBH binary hardening rate becomes practically independent of the mass resolution of the stellar bulge. The SMBHs coalesce on average 200 Myr after the formation of the SMBH binary. However, small differences in the initial SMBH binary eccentricities can result in large differences in the SMBH coalescence times. Finally, we discuss the future prospects of KETJU, which allows for a straightforward inclusion of gas physics in the simulations.

On the odderon mechanism for transverse single spin asymmetry in the Wandzura-Wilczek approximation

description: We compute the transverse single spin asymmetry in forward $p^\uparrow p \to hX$ and $p^\uparrow A \to hX$ collisions from the odderon mechanism originally suggested by Kovchegov and Sievert [1]. Working in the hybrid approach of the Color Glass Condensate effective theory we firstly identify the relevant collinear parton distribution function (PDF) of the transversely polarized proton $p^\uparrow$ as the intrinsic twist-3 $g_T(x)$ distribution. We further argue that the complete polarized cross section also contains contributions from the kinematical and the dynamical twist-3 PDFs, in addition to the intrinsic twist-3 PDF. By restricting to the Wandzura-Wilczek approximation, where the dynamical twist-3 PDFs are dropped, we find that the odderon contribution to the polarized cross section for inclusive hadron production is exactly zero at the next-to-leading order in the strong coupling.

description: In this work we construct a novel dissipaton-equation-of-motion (DEOM) theory in quadratic bath coupling environment, based an extended algebraic statistical quasi-particle approach. To validate the new ingredient of the underlying dissipaton algebra, we derive an extended Zusman equation via a totally different approach. We prove that the new theory, if it starts with the identical setup, constitutes the dynamical resolutions to the extended Zusman equation. Thus, we verify the generalized (non-Gaussian) Wick's theorem with dissipatons-pair added. This new algebraic ingredient enables the dissipaton approach being naturally extended to nonlinear coupling environments. Moreover, it is noticed that, unlike the linear bath coupling case, the influence of a non-Gaussian environment cannot be completely characterized with the linear response theory. The new theory has to take this fact into account. The developed DEOM theory manifests the dynamical interplay between dissipatons and nonlinear bath coupling descriptors that will be specified. Numerical demonstrations will be given with the optical line shapes in quadratic coupling environment.

description: La creciente demanda energética del sector industrial de Mamonal y la necesidad del consumo eléctrico continuo en procesos químicos y físicos a gran escala, llevan a ciertas empresas a instalar plantas, para el autoabastecimiento térmico y eléctrico, esto sumado a la importancia de conocer que tan eficientes son los equipos encargados de la transformación energética, conllevan a la realización de un análisis termodinámico. En este estudio, se presenta el desarrollo de un análisis exergético a un ciclo combinado, en la planta de servicios industriales de la empresa Abocol S.A, para ello se definieron las condiciones de operación basadas en datos reales de la planta, posteriormente se dividió al sistema en volúmenes de control a los cuales se le realizaron balances de energía y exergía, esto permitió localizar los principales focos de ineficiencia debida a las irreversibilidades de este ciclo de potencia. El ciclo combinado empleado en Abocol S.A, cuenta con la capacidad de producir hasta 24 MW, de los cuales 12.5 MW son producidos por el ciclo de gas y 11.5MW por el ciclo de vapor, los resultados obtenidos de el análisis exergético, mostraron que las calderas son las principales contribuyentes a la destrucción de exergía, con un valor de 23 % para la caldera 305 y 7% para las calderas 104 y 103, estos equipos también presentaron las eficiencias exergéticas más bajas, con valores entre el 53.9% y el 59.7%, esto debido a las irreversibilidades inherentes al proceso de combustión y al de intercambio de calor. Por último se encontró que existe una baja considerable en la eficiencia exergética del ciclo combinado en comparación a otros ciclos similares, debido al bajo aporte de el ciclo de Rankine a la generación de energía eléctrica solo aporta en promedio un 11.3 % a la eficiencia global del ciclo, porcentaje bajo en comparación al 32.4 % aportado por el ciclo Joule-Brayton, pero que está sujeto a los requerimientos de vapor en otras plantas de la empresa.
