CLASSIFICATION OF WHEAT LEAF SEPTORIA DISEASE USING IMAGE PROCESSING AND MACHINE LEARNING TECHNIQUES
Creators: name: MEQUANNT KAHSAY
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019
Subjects: agriculture; classification; image processing; leaf disease; septoria; wheat

description: Education, health and food security are the three main concerns of developing countries
 including Ethiopia, and it’s clear that agriculture is the most powerful factor for the growth
 of Ethiopian economy. In addition to this, for citizens in order to keep them alive, at least
 planning of food security program is very essential and for these programs to achieve
 sufficient productivity of farming fields is expected. One way of making productive field
 is the serious care of its elements which begins with growing healthy plants or crops. For
 this to achieve a farmer or an agriculture expert should follow up, diagnose a field and
 make decisions accordingly. Farmers and agriculture experts visually carry out
 examination of crops. However, this evaluation process is tedious, time consuming, and
 less accurate, which can cause high risk of loss later. Image processing and machine
 learning have been extensively used in various disease diagnosis approaches. It has been
 applied to both images captured from cameras of visible light and from equipment that
 captures information in invisible wavelength, assisting experts to select the right measure
 and treatment. In this research work, a digital camera captured image is used as input and
 enhanced with various preprocessing techniques followed by color-based segmentation
 method to separate the regions of interest then features are extracted using Gray Level Cooccurrence
 Matrix. Classification of the input image is performed at the final stage taking
 four different supervised learning algorithms to classify in to two different classes called
 ‘healthy’ and ‘infected’. All the work is done using Python and supporting libraries. Naïve
 Bayes, k-Nearest Neighbor, Support Vector Machines and Random Forest are the
 classification algorithms taken for comparison. Based on a confusion matrix evaluation
 Random Forest found to be the best with 98.7 % accuracy of classification.

description: An inherent difficulty in studying mesoscopic effects in semiconductor--superconductor hybrid structures is the large Schottky barrier which often forms at the interface. A large technological effort has been invested in in improving the contact between the superconductor and the two-dimensional electron gas (2DEG) of a semiconductor heterostructure, and in recent years this has become possible for e.g. GaAs-Al, GaAs-In, and InAs-Nb junctions. This development motivates quantitative theoretical modeling of sample-specific transport properties. The aim of our work is to model the conducting properties of a ballistic 2DEG-S interfaces with a QPC in the normal region and also to take into account scattering due to a weak Schottky barrier and/or non-matching Fermi properties of the semiconductor and superconductor.

Classifying 5d SCFTs via 6d SCFTs: Arbitrary rank

description: According to a conjecture, all 5d SCFTs should be obtainable by rank-preserving RG flows of 6d SCFTs compactified on a circle possibly twisted by a background for the discrete global symmetries around the circle. For a 6d SCFT admitting an F-theory construction, its untwisted compactification admits a dual M-theory description in terms of a "parent" Calabi-Yau threefold which captures the Coulomb branch of the compactified 6d SCFT. The RG flows to 5d SCFTs can then be identified with a sequence of flop transitions and blowdowns of the parent Calabi-Yau leading to "descendant" Calabi-Yau threefolds which describe the Coulomb branches of the resulting 5d SCFTs. An explicit description of parent Calabi-Yaus is known for untwisted compactifications of rank one 6d SCFTs. In this paper, we provide a description of parent Calabi-Yaus for untwisted compactifications of arbitrary rank 6d SCFTs. Since 6d SCFTs of arbitrary rank can be viewed as being constructed out of rank one SCFTs, we accomplish the extension to arbitrary rank by identifying a prescription for gluing together Calabi-Yaus associated to rank one 6d SCFTs.

description: Using the general notions of Batalin, Fradkin, Fradkina and Tyutin to convert second class systems into first class ones, we present a gauge invariant formulation of the massive Yang-Mills theory by embedding it in an extended phase space. The infinite set of correction terms necessary for obtaining the involutive constraints and Hamiltonian is explicitly computed and expressed in a closed form. It is also shown that the extra fields introduced in the correction terms are exactly identified with the auxiliary scalars used in the generalized Stückelberg formalism for converting a gauge noninvariant Lagrangian into a gauge invariant form.

description: A number of attempts have recently been made to extend the conjectured $S$ duality of Yang Mills theory to gravity. Central to these speculations has been the belief that electrically and magnetically charged black holes, the solitons of quantum gravity, have identical quantum properties. This is not obvious, because although duality is a symmetry of the classical equations of motion, it changes the sign of the Maxwell action. Nevertheless, we show that the chemical potential and charge projection that one has to introduce for electric but not magnetic black holes exactly compensate for the difference in action in the semi-classical approximation. In particular, we show that the pair production of electric black holes is not a runaway process, as one might think if one just went by the action of the relevant instanton. We also comment on the definition of the entropy in cosmological situations, and show that we need to be more careful when defining the entropy than we are in an asymptotically-flat case.

COMPARATIVE STUDY ON THE PERFORMANCES OF PROPORTIONAL INTEGRAL DERIVATIVE (PID) AND MODEL PREDICTIVE CONTROL (MPC) FOR CONTROLLING SHELL AND TUBE HEAT EXCHANGERS

Publisher: name: National Academic Digital Repository of Ethiopia

description: In many industrial process and operations heat exchangers are one of the most important thermal
 devices. Shell and tube heat exchangers are the common types of heat exchangers and sustained
 a wide range of operating temperature and pressure. Controlling heat exchanger system is a very
 challenging task due to its nonlinearity. While the amount of flow rates of both manipulated
 variable and disturbance variable changes, the gain, time delay and time constant varies, hence
 causing system nonlinearity. The solution for such problems is finding mathematical model that
 represents the real system and designing suitable controller which remove the offset, making fast
 settling with minimum steady state error possible. Input data for MATLAB system identification
 tool was generated experimentally. Experimental (empirical) based modeling has been used in this
 work. Due to system nonlinearities, the overall system is partitioned in to particular operating
 range. For this particular operating range input-output data has been collected and interpreted
 using MATLAB. Lastly, the plant and disturbance models have been obtained. Then, the next step
 after modelling is to design controllers using Proportional Integral Derivative (PID) and Model
 Predictive Control (MPC) and compare the results. Based on the results of the work, MPC was
 found to have a better performance than that of PID controller. For instances, the MPC
 performance indices are, 0.064 % overshoot, and settling time of 10.5 seconds, While the PID
 resulted 2.577 % overshoot, and settling time of 63.1 seconds. These results demonstrated that
 MPC controller is more effective for critical process control application and achieve fast and
 offset free control. Therefore, application of MPC controller in industries is highly recommended
 as it enables increased product quality at lower cost and in lesser time

A direct transition from the a- to the i-phase occurs for Al-Cu-Fe films at 430 C on the time scale of minutes. The resulting films are of good quality as shown by diffraction and electronic transport properties. The surface of the resulting films is very smooth.

description: We propose a phenomenological approach to examine the role of short- and long-range nucleon-nucleon correlations in the quenching of single-particle strength in atomic nuclei and their evolution in asymmetric nuclei and neutron matter. These correlations are thought to be the reason for the quenching of spectroscopic factors observed in $\rm (e,e'p)$, $\rm (p,2p)$ and transfer reactions. We show that the recently observed increase of the high-momentum component of the protons in neutron-rich nuclei is consistent with the reduced proton spectroscopic factors. Our approach connects recent results on short-range correlations from high-energy electron scattering experiments with the quenching of spectroscopic factors and addresses for the first time quantitatively this intriguing question in nuclear physics, in particular regarding its isospin dependence. We also speculate about the nature of a {\sl quasi-proton} (nuclear polaron) in neutron matter and its kinetic energy, an important quantity for the properties of neutron stars.

description: D^0-\bar{D}^0 mixing at the detectable level or significant CP violation in the charm system may strongly signify the existence of new physics. In view of the large discovery potential associated with the fixed target experiments, the B-meson factories and the τ-charm factories, we make a further study of the phenomenology of D^0-\bar{D}^0 mixing and CP violation in neutral $D$-meson decays. The generic formulas for the time-dependent and time-integrated decay rates of both coherent and incoherent D^0\bar{D}^0 events are derived, and their approximate expressions up to the second order of the mixing parameters x_D and y_D are presented. Explicitly we discuss D^0-\bar{D}^0 mixing and various CP-violating signals in neutral D decays to the semileptonic final states, the hadronic CP eigenstates, the hadronic non-CP eigenstates and the CP-forbidden states. A few non-trivial approaches to the separate determination of x_D and y_D and to the demonstration of direct and indirect CP asymmetries in the charm sector are suggested.
description: Latex 42 pages (including 6 PS figures). Minor changes: a) the more popular notation for D^0-\bar{D}^0 mixing is adopted; b) the possibility to test CPT symmetry in D^0-\bar{D}^0 system is not overrated. The present version is going to appear in Phys. Rev. D 1 (January 1997)
Automated Dataset Generation System for Collaborative Research of Cyber Threat Analysis

description: The objectives of cyberattacks are becoming sophisticated, and attackers are concealing their identity by masquerading as other attackers. Cyber threat intelligence (CTI) is gaining attention as a way to collect meaningful knowledge to better understand the intention of an attacker and eventually predict future attacks. A systemic threat analysis based on data acquired from actual cyber incidents is a useful approach to generating intelligence for such an objective. Developing an analysis technique requires a high volume and fine quality data. However, researchers can become discouraged by an inaccessibility to data because organizations rarely release their data to the research community. Owing to a data inaccessibility issue, academic research tends to be biased toward techniques that develope steps of the CTI process other than analysis and production. In this paper, we propose an automated dataset generation system called CTIMiner. The system collects threat data from publicly available security reports and malware repositories. The data are stored in a structured format. We released the source codes and dataset to the public, including approximately 640,000 records from 612 security reports published from January 2008 to June 2019. In addition, we present a statistical feature of the dataset and techniques that can be developed using it. Moreover, we demonstrate an application example of the dataset that analyzes the correlation and characteristics of an incident. We believe our dataset will promote collaborative research on threat analysis for the generation of CTI.

description: Managing an enterprise is perhaps even great deal and Organizational design in the context of constraints. Getting Deeper into the subject of differential productivity in the start-up resource assembly process is therefore important for the woman entrepreneur, who in addition to all the business problems must deal with the problems of being women in a traditionally male –dominated arena. In spite of the obstacles, the number of women entrepreneurs is increasing day by day. This growth in the number of women entrepreneurs and the additional 85% of all women says that they would like to be in business for themselves. Implementing policies to support women's small and medium business will require considerable cost. Research conducted in advanced countries reveals that Women Entrepreneur managed new ventures perform better when they both identify innovative ideas and also assemble human assets with expertise in structuring organizational arrangements to commercialize those ideas. An important implication is that organizational resources have a range of potential values, and that realizing the upper range of value capture involves the additional ability to structure organizational relationships. Women's businesses have been playing a leading role in technological innovation and job creation. Women Entrepreneurs are good leaders and managers in expanding the lowest stratum of medium and small enterprises which will lead to balanced entrepreneurial development

description: In this paper, the phytochemical analysis on the inflorescences (flowers and bracts) of a sample of Tilia tomentosa collected from an isolated population in Central Italy, was reported for the first time. Thirteen compounds (oleanolic acid, maslinic acid, apigenin, luteolin, kaempferol, quercetin, kaempferol-3-O-glucoside, quercetin-3-O-glucoside, rutin, tiliroside, ellagic acid, shikimic acid and quinic acid), belonging to several different classes of natural products, were identified on the basis of spectroscopic and spectrometric analysis. This sample was found to be mainly composed by flavonoids, followed by organic acids and pentacyclic triterpenes. The chemosystematic aspects of the identified components were also discussed, together with their pharmacologic relevance with respect to the traditional medicinal uses of this plant material.

description: By means of the plane wave method we study spin wave dynamics in two-dimensional bi-component magnonic crystals based on a squeezed hexagonal lattice and consist of a permalloy thin film with cobalt inclusions. We explore the dependence of a spin wave frequency on the external magnetic field, especially in weak fields where the mode softening takes place. For considered structures, the mode softening proves to be highly non-uniform on both the mode number and the wave vector. We found this effect to be responsible for the omnidirectional band gap opening. Moreover, we show that the enhancement of the demagnetizing field caused by the squeezing of the structure is of crucial importance for the non-uniform mode softening. This allows us to employ this mechanism to design magnonic gaps with different sensitivity for the tiny change of the external field. The effects we have found should be useful in designing and optimization of spin wave filters highly tunable by a small external magnetic field.

description: Spin current is a central theme in spintronics, and its generation is a keen issue. The spin-polarized current injection from the ferromagnet, spin battery, and spin Hall effect have been used to generate spin current, but Ohmic currents in the normal state are involved in all of these methods. On the other hand, the spin and spin current manipulation by the supercurrent in superconductors is a promising route for dissipationless spintronics. Here we show theoretically that, in two-dimensional superconductors with Rashba spin-orbit interaction, the generation of dissipationless bulk spin current by charge supercurrent becomes highly efficient, exceeding that in normal states in the dilute limit, i.e. when the chemical potential is close to the band edge, although the spin density becomes small there. This result manifests the possibility of creating new spintronic devices with long-range coherence.

description: Cuccìa is a traditional Sicilian food prepared by boiling whole durum wheat kernels, in water, for many hours. This process destroys the vitamins E and B contents of crude kernels. It was rated a method to prepare the Cuccìa, preserving the vitamin content. Four varieties of durum wheat were processed comparing the traditional cooking method (TR-boiling for 5/6 hours), and an innovative one (IN-grains scarification, germination, and cooking at 50 °C for 2 hours). On soups obtained the content of biotin, niacin and α-amylase activity were determined. ANOVA showed the cooking method influences biotin and niacin content having values from 0.56 and 0.72 ng ml−1 (raw grain) and values close to 0 (TR), while only a 10% decrease (IN) respectively for both vitamins. On the contrary, α-amylase activity was reduced with IN method. The IN method combined with ancient grains, produces the soup with a good vitamin B amount.

In the same nonintegrable Hamiltonian, we discover several eigenstates at \emph{infinite temperature} that can be represented exactly as matrix product states with finite bond dimension, for both periodic boundary conditions (two exact $E = 0$ states) and open boundary conditions (two $E = 0$ states and one each $E = \pm \sqrt{2}$). This discovery explicitly demonstrates violation of strong eigenstate thermalization hypothesis in this model and uncovers exact quantum many-body scar states. These states show signatures of translational symmetry breaking with period-2 bond-centered pattern, despite being in one dimension at infinite temperature. We show that the nearby many-body scar states can be well approximated as "quasiparticle excitations" on top of our exact $E = 0$ scar states, and propose a quasiparticle explanation of the strong oscillations observed in experiments.

description: The paper of Unal [J. Math. Phys. 59, 062104 (2018)], though worthy of attention, contains a conclusion that is in error and may mislead the efforts to extend his results. The aim of the present note is twofold: we provide a correction to such a conclusion and then we emphasize some missing points that are necessary to clarify the content of the paper.

description: In this paper, the phytochemical analysis on the inflorescences (flowers and bracts) of a sample of Tilia tomentosa collected from an isolated population in Central Italy, was reported for the first time. Thirteen compounds (oleanolic acid, maslinic acid, apigenin, luteolin, kaempferol, quercetin, kaempferol-3-O-glucoside, quercetin-3-O-glucoside, rutin, tiliroside, ellagic acid, shikimic acid and quinic acid), belonging to several different classes of natural products, were identified on the basis of spectroscopic and spectrometric analysis. This sample was found to be mainly composed by flavonoids, followed by organic acids and pentacyclic triterpenes. The chemosystematic aspects of the identified components were also discussed, together with their pharmacologic relevance with respect to the traditional medicinal uses of this plant material.

description: It is known that the spin structure on a Riemannian manifold can be extended to noncommutative geometry using the notion of a spectral triple. For finite geometries, the corresponding finite spectral triples are completely described in terms of matrices and classified using diagrams. When tensorized with the ordinary space-time geometry, finite spectral triples give rise to Yang-Mills theories with spontaneous symmetry breaking, whose characteristic features are given within the diagrammatic approach: vertices of the diagram correspond to gauge multiplets of chiral fermions and links to Yukawa couplings.

title: Essays on household finance, venture capital, and labor

description: In the first chapter, I study households’ insurance decisions against flood risk. Flooding is the most costly natural disaster in the US, yet policymakers are puzzled by the low take-up for flood insurance. I argue that households are affected by the low salience of flood risk. Leveraging novel transaction-level data, I use two empirical strategies to support my hypothesis. First, I exploit a staggered campaign that publicizes already freely-available flood risk information. Insurance purchases increase by 30.6% in response. Second, I exploit salient flood events shared through social media. Households purchase significantly more insurance after their geographically distant peers experience floods. My results suggest that behavioral frictions have a major impact on households’ insurance decisions. Chapter two studies the role of venture capitalists (VCs) in the labor market for entrepreneurs. There is an ongoing debate on whether VCs bet on ideas or founders. Prior studies find that successful startups often have kept businesses stable but replaced founders; however, practitioners see founders as more critical. This paper aims to rationalize the two views. I analyze new hand-collected data and find that VCs redeploy entrepreneurs across portfolio companies, highlighting VCs’ emphasis on human capital. I propose that VCs utilize private information about founders, and I show: (1) former VC partners continue influencing founders’ mobility; (2) the redeployment positively predicts VC performance; (3) the redeployment is stronger where information is more asymmetric. In the third chapter (co-authored with Ashwini Agrawal and Isaac Hacamo), we find that rank-and-file labor flows can be used to predict abnormal stock returns. Rank-and-file employees are becoming increasingly critical for many firms, yet we know little about how their employment dynamics matter for stock prices. We analyze new data from the individual CV’s of public company employees and find that rank-and-file labor flows can be used to predict abnormal stock returns. Accounting data and survey evidence indicate that workers’ labor market decisions reflect information about future corporate earnings. Investors, however, do not appear to fully incorporate this information into their earnings expectations. The findings support the hypothesis that rank-and-file employees’ entry and exit decisions convey valuable insight into their employers’ future stock performance.

description: In high-Tc cuprates, the orbital magnetoresistance in plane (MR, $Δρ/ρ$) is anomalously enhanced at lower tempemeratures compared with conventional Fermi liquids, and thus Kohler's rule is strongly violated. Moreover, it should be noted that an intimate relation between the MR and the Hall coefficient ($R_H$), $Δρ/ρ\propto (R_H/ρ)^2$, holds well experimentally, and is called the "modified Kohler's rule". In this letter, we study this long-standing problem in terms of the nearly antiferromagnetic (AF) Fermi liquid. We analyze the exact expression for the MR by including the vertex corrections (VC's) to keep the conservation laws, and find the approximate "scaling relation" $Δρ/ρ\propto ξ_{AF}^4 /ρ^2$ ($ξ_{AF}$ being the AF correlation length.) in the presence of AF fluctuations. The factor $ξ_{AF}^4$, which comes from the VC's for the current, gives the additional temperature dependence. By taking account of the relation $R_H \propto ξ_{AF}^2$ [Kontani et al., PRB 59 (1999) 14723.], we can naturally explain the modified Kohler's rule. In conclusion, based on the Fermi liquid theory, the famous {\it seemingly} non-Fermi liquid behaviors of the Hall coefficient and the MR in high-Tc cuprates are naturally understood on an equal footing.

description: Six fish species (Labeo calbasu, Puntius ticto, Notopterus notopterus, Labeo rohita, Channa punctatus, and Aorichthys seenghala) were selected from Dimna Lake, Jamshedpur, India. Metal(loid) (As, Cd, Cr, Cu, Hg, Pb, and Zn) concentrations were assessed in gill, muscle, intestine, liver, and caudal fin of each fish species. The result showed that the concentrations of Cd (2.16–3.87 mg/kg), Cr (2.22–9.97 mg/kg), Hg (0.09–1.99 mg/kg), Pb (12.00–39.65 mg/kg), and Zn (97.20–376.02 mg/kg) were higher than that of previous research and international standard. Industrial discharge, vehicular emission and agricultural run-off were responsible sources of elevated concentration of these metal(loids). Among different organs, highest concentrations were observed in gill, liver and intestine may be attributed to the physiology of organs and their interaction with the environment. Among different fish species, carnivorous and bottom feeders concentrate more metal(loid)s. The potential human health risk due to consumption of fish species was assessed by Target Hazard Quotient (THQ) and Hazard Index (HI) of metal(loid)s. The result showed the value of THQ greater than 1 and the value of HI within 2.7–15.1. These results showed a serious threat (especially due to lead and mercury) to the local population consuming fish from Dimna Lake.

description: The Soil Data Assimiliation Guidance wiki is a collaborative effort to collect and describe hands-on good practices on data assimilation in the soil domain, with a focus on Europe. The term Soil data assimilation has been chosen by the autors as an alternative to the terms harmonisation and standardisation, which already have a specific meaning in the soil domain:

standardisation; aligning soil data to a common model, using common codelists.

harmonisation; transforming results from observations and measurements to values as if all results for a property are measured using the same procedure, by applying so called Pedotransfer Functions (PTF).

The process of assimilation also aims to capture additional aspects, such as finding, downloading and using the data. Most of these aspects are also well described as part of the FAIR principles.

The “Infrastructure for Spatial Information in the European Community” (INSPIRE) directive has been and is an important effort for standardisation in the environmental data domain, therefore this wiki has many links to INSPIRE sources. Because INSPIRE adopts industry standards, this wiki does reference common standards from ISO (International Organization for Standardization), Open Geospatial Consortium, Global Soils Partnership, IANA (Internet Assigned Numbers Authority) and W3C (World Wide Web Consortium), giving it a global relevance.

This guide was initiatied by ISRIC - World Soil Information and Wageningen Environmental Research as part of the European Joint Program on Soil (EJP Soil) with funding from the European Union’s horizon 2020 research and innovation programme under grant agreement No. 862695.
Excluding Light Gluinos from Z decays

description: We reanalyze the constraints on light gluinos (m_{\tilde{g}}\leq 5 GeV/c^2) from the hadronic Z decays into four jets. We find that the published OPAL data from the 1991 and 1992 runs exclude a light quasi-stable gluino with mass \lesssim 1.5 GeV/c^2 at more than 90% confidence level. This limit depends little on assumptions about the gluino fragmentation and the definition of the gluino mass. The exclusion confidence level is shown as a function of the mass. A future projection is briefly discussed. We also discuss quantitatively how the distributions in the Bengtsson-Zerwas and the modified Nachtmann-Reiter angles change due to the finite bottom quark or gluino mass. The analysis is limited to the leading-order calculations. We, however, give an empirical reason to why the next-to-leading-order corrections are unlikely to change our conclusions.
