Master’s Thesis Proposal – Master of Science in Natural Resources

Master’s Thesis Proposal – Master of Science in Natural Resources Introduction Natural resources administration is a complex field primarily administered via the public-sector (local, state, and federal agencies). Managers in this field are regularly tasked with complicated issues such as reducing conflict between opposing interests on public lands (i.e. passive recreation versus extractive industries), providing quality educational and recreational experiences to the citizens they serve, promoting interagency collaboration and cooperation, constructing and maintaining safe and appropriate infrastructure, and increasing the level of professionalism among the employees of their respective agency, among others. The increasing competition for expanding programs at all levels of government has placed even greater priority on locating and securing sustainable funding necessary to serve the public in an effective manner. Budget resource scarcity, severe staff reductions, and service demands have placed public organizations under great pressure to apply better planning techniques (Eadie, 1983). This dilemma has driven public-sector natural resource managers to innovate and utilize creative strategies in an overall effort to sustain staff satisfaction, enhance service quality, and place their agencies in position to garner increased budget allocations. Due to these and other factors, strategic planning has emerged as a tool that may be used by natural resource managers to identify critical issues and develop comprehensive strategies to address those issues in an effort to accomplish goals and create positive organizational change. Although the practice of strategic planning was once prevalent only in the private sector business world, government leaders have become increasingly interested in strategic planning since the early 1970’s as a result of

Irreducibility of the moduli space of vector bundles on surfaces and Brill-Noether theory on singular curves

We prove the irreducibility of the moduli space of rank 2 semistable torsion free sheaves (with a generic polarization and any value of c_2) on a K3 or a del Pezzo surface. In the case of a K3 surface, we need to prove a result on the connectivity of the Brill-Noether locus for singular curves on the surface. In the case of a del Pezzo surface, we reduce the problem to the case of P^2 by first relating the moduli spaces of the plane and the blown-up plane, and then studying how the moduli space changes when we change the polarization.
In-Vitro Evaluation of Novel Polycaprolactone/ Chitosan/ Carbon Nano Tube Scaffold for Tissue Regeneration

Background: Many patients lose their organs or tissues due to disease, trauma, or a variety of genetic disorders. Tissue engineering is a multidisciplinary science to regenerate or restore tissue or organ function and an appropriate scaffold is the first and certainly a crucial step in tissue engineering strategies. Objective: The purpose of this study is to fabricate and evaluate the in-vitro response of porous nano Polycaprolactone (PCL)/ chitosan/ multi-wall carbon nanotube (MWCNTs) scaffold for tissue regeneration. Material and Methods: In this experimental research, a novel scaffold containing MWCNTs in polycaprolactone/chitosan nanofibrous scaffold was synthesized by electrospinning technique. Results: According to scanning electron microscopy SEM images, by increasing the number of MWCNT in the scaffold by 2%, the average diameter decreased significantly for fabricated scaffolds with 5% MWCNTs. Based on the results, the scaffolds plunged from submicron to nanoscale fibers at about 80 nm. In addition, by adding more MWCNT to the nanofibrous scaffold, the biodegradation rate was decreased by 32%. However, mechanical characterization demonstrates that the higher level of MWCNT increases young modulus by 96%, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay illustrated that MWCNTs could enhance bioactivity and cell- scaffold relationship in addition to alkaline phosphatase (ALP). Conclusion: MWCNT significantly improves the physical and mechanical properties of fabricated scaffolds and in-vitro assessment demonstrated that the prepared nanofibrous scaffold containing 4% MWCNT could be a very useful biocompatible material for tissue engineering.
Stroke risk evaluation for patients with atrial fibrillation: Insights from left atrial appendage

Left atrial appendage (LAA) is believed to be a common site of thrombus formation in patients with atrial fibrillation (AF). However, the commonly-applied stroke risk stratification model (such as. CHA2DS2-VASc score) does not include any structural or hemodynamic features of LAA. Recent studies have suggested that it is important to incorporate LAA geometrical and hemodynamic features to evaluate the risk of thrombus formation in LAA, which may better delineate the AF patients for anticoagulant administration and prevent strokes. This review focuses on the LAA-related factors that may be associated with thrombus formation and cardioembolic events.
Integer powers of complex anti-tridiagonal matrices and some complex factorizations

In this paper, we obtain a general expression for the entries of the rth power of a certain n-square complex anti-tridiagonal matrix where if n is odd, r is integer or if n is even, r is natural number. In addition, we get the complex factorizations of Fibonacci polynomials, Fibonacci and Pell numbers.
Robust tracking and disturbance rejection under physical parameter uncertainties for polynomial-exponential signals

The robust asymptotic tracking and disturbance rejection problem is solved for linear time-invariant systems whose matrices are assumed to depend on some parameters (each of which possibly affects all the elements of the matrices describing the system, thus playing the role of a physical parameter) and for classes of disturbance functions and reference signals of the polynomial-exponential type. It is assumed that reference commands exist only for some of the controlled outputs (i.e., that some scalar outputs must only be regulated), and that different subvectors of the reference vector are characterized by different classes of signals. The application of the theory developed to a flexible robot arm is presented. <<ETX>>
Hierarchical Bayesian models for road accident data

This paper is concerned with models for accident numbers at sites within a road network. It highlights the need to analyse data in a disaggregated form, rather than considering total accidents at a site. Obviously it is easier to analyse the data in a more aggregated form, but this approach can overlook important aspects of the underlying phenomena and misleading conclusions may be drawn from an aggregated analysis. The data analysed in this paper concern 156 single-carriageway link sites in Kent. The models proposed are multiple response models, where different types of accident (according to severity and the number of vehicles involved) are modelled simultaneously. Two quite similar classes of model are investigated. Both classes can be described as mixed generalised linear models, or hierarchical models, with the mean of each response variable equal to the product of a random effect and a regression term based on important explanatory variables such as speed limit, link length and estimated traffic. For one class the random effect is gamma distributed and for the other class it is a log-Normal random effect. The models are hierachical Bayesian, structuring the unknown parameters in different layers. In this way a better stochastic approximation is proposed of the causal machinery producing the phenomenon analysed. Inference is based on empirical quantities describing the posterior distributions of the parameters of interest. The multi-dimensional integrals involved in the analysis are approximated using Markov Chain Monte Carlo methods. (A)
Edge ideals: algebraic and combinatorial properties

Let C be a clutter and let I(C) be its edge ideal. This is a survey paper on the algebraic and combinatorial properties of R/I(C) and C, respectively. We give a criterion to estimate the regularity of R/I(C) and apply this criterion to give new proofs of some formulas for the regularity. If C is a clutter and R/I(C) is sequentially Cohen-Macaulay, we present a formula for the regularity of the ideal of vertex covers of C and give a formula for the projective dimension of R/I(C). We also examine the associated primes of powers of edge ideals, and show that for a graph with a leaf, these sets form an ascending chain.
Comparison of serum troponin level and echocardiographic parameters between male and femal patients with ACS

Background: Acute Coronary Syndrome is one of the commonly diagnosed life threatening condition as of now. Hence it is necessary to diagnose early and assess the severity of disease as soon as possible. Troponin is considered a specific marker for the diagnosis of acute coronary syndrome (ACS). Aim: To estimate the high-sensitivity cardiac troponin (hs-cTn) in Acute coronary syndrome patients. Also to compare serum troponin levels and echocardiographic parameter in patient's gender. Materials and Methods: 70 patients of both sexes who got admitted within 24 hours after onset of symptoms and diagnosed as Acute Coronary Syndrome in Hospital of Baghdad /medical city during the period of December 2020 to December 2021. The (hs-cTn) was measure in the blood with Elisa Assay kit. Results: This study included 70 patients, they divided into two groups: Male group and female group. The control group included 20 healthy persons. There was a significant increase in the frequency of ACS among males in comparison to females (P-value =0.0027). The mean (± SEM) value of serum hs-troponin I concentrations did not differ significantly (p=0.372) as compared with mean (± SEM) value of serum control group.
An Allard type regularity theorem for varifolds with H\"older continuous generalized normal

We prove that Allard's regularity theorem holds for rectifiable $n$-dimensional varifolds $V$ assuming a weaker condition on the first variation. This, in the special case when $V$ is a smooth manifold translates to the following: If $\omega_n^{-1}\rho^{-n}{\rm area}(V\cap B_\rho(x))$ is sufficiently close to $1$ and the unit normal of $V$ satisfies a $C^{0,\alpha}$ estimate, then $V\cap B_{\rho/2}(x)$ is the graph of a $C^{1,\alpha}$ function with estimates. Furthermore, a similar boundary regularity theorem is true.
Adaptive genetic algorithms-modeling and convergence

The paper presents a new mathematical analysis of genetic algorithms (GAs); we propose the use of random systems with complete connections (RSCC), a non-trivial extension of the Markovian dependence, accounting for a complete, rather than recent, history of a stochastic evolution. As far as we know, this is the first theoretical modeling of an adaptive GA. First we introduce the RSCC model of an p/sub m/-adaptive GA, then we prove that a "classification of states" is still valid for our model, and finally we derive a convergence condition for the algorithm.
Optimisation of the ILC vertex detector and study of the Higgs couplings

This thesis is a contribution to the " Detector Baseline Document ", describing the ILD detector which is intendedfor the International Linear Collider (ILC). The physics goals of the ILD call for a vertex detector (VXD) particularly light, rapid and very granular allowing toreach an unprecedented resolution on the impact parameter of the tracks that reconstruct the particles producedin the studied interactions. The principle goal of this thesis is to show how to optimise the parameters of the VXDin the case that is composed of Active Pixel Sensors manufactured in industrial CMOS technology (CAPS). Thiswork has been realised by studying the sensitivity of the performance of the heavy flavour tagging and theprecision on the hadronic branching fractions of the Higgs boson as a function of different sets of VXDparameters.The specifications of the VXD, particularly ambitious, call for the development of a novel silicon pixel sensorstechnology, the CAPS, which was pioneered by the PICSEL group of IPHC. The readout speed and the influenceof the fabrication parameters have been studied in this thesis, and CAPS prototypes have been characterised intest beams. Finally, the tracking performance of a CAPS based VXD has been evaluated with simulation studies.
The Modifications of the Anterior Cruciate Ligament Rupture Physical Therapy Caused by the Anterolateral Ligament Injury

The anterolateral ligament (ALL) is a rotational stabilizer of the knee joint widely investigated the last 13 years as the possible cause of some anterior cruciate ligament (ACL) reconstructions failure. ALL injuries accompany 64% of ACL ruptures. Nevertheless, there are still no publications concerning changes in the ACL rehabilitation process due to the ALL concomitant rupture. We evaluated rotational stability in 12 athletes with the ACL rupture and concomitant ALL injury or Segond fracture treated conservatively before the treatment and 3 months later. The physical therapy comprised the range of motions and strengthening exercises during the immobilization period and thereafter. As only the knee joint was immobilized the physical therapy was conducted to the adjacent joints and muscles at the very beginning. A total of 83.33% of patients became pivot-shift negative in three months. In 16.67% pivot-shift test was questionable. Lachman test remained positive in 91.67%. The ACL is a more important structure than the ALL. So, our treatment strategy focuses mainly on it. Most changes in physical therapy are the immobilization and postponed axial loading with internal rotation. But even these minor changes may influence greatly the overall stability of the knee, particularly rotational stability. It seems to be the single case series as- sessing the rotational stability recovery after the ALL rupture conservative treatment we found in the scientific literature. Immobilization and non-weightbearing for up to 6 weeks may decrease the rotational instability in con- servatively treated ALL injuries concomitant to the ACL ruptures. Further investigations of the physical therapy and rehabilitation of the anterolateral ligament injuries and Segond fractures are necessary.

Salinity and medicinal plants: Challenges and strategies for production

Medicinal plants, since antiquity, have been relevant due to their therapeutic properties, are widely used for the prevention and treatment of diseases. However, the growth and production of these plants are impacted by a notorious environmental stressor, salinity. In this sense, this study aimed to review the impacts of salinity on plant development, the deleterious effects of this environmental stressor on the production of medicinal plants, and the production strategies of these species in saline conditions. Areas with salt excess problems have been increasing all over the planet, mainly due to human actions such as inadequate irrigation management. Salinity impacts plants at different times, the first phase results from osmotic stress, while the second derives from the ionic toxicity of the salt constituents. In medicinal plants, saline stress causes damage from germination to changes in morphological characteristics, physiology, nutrient concentration, and productivity. However, in some species, exposure to moderate degrees of salinity was positive for medicinal quality, with an improvement in the constitution of the essential oil. Strategies for the production of medicinal plants in saline conditions are reported in the literature, such as the use of amino acids (such as proline and betaine glycine), salicylic acid, arbuscular mycorrhizal fungi, resistance inducing genes, and projected nanoparticles. These strategies may represent an option for agricultural production in marginal areas and with waters with higher levels of salts.
Component masses and inclination of binary systems containing a pulsar, determined from relativistic effects

The first-order Doppler-effect term in the period of a pulsar in a binary system can yield a mass function involving the masses of both components and the orbital inclination and eccentricity. The relativistic rotation of the line of apsides would serve to establish the combined mass of the components. To determine the masses of the pulsar and its companion separately, one must include second-order effects in the pulsar frequency shift: the gravitational red shift and the quadratic Doppler effect. However, the variable part of these effects is proportional to a single component of the pulsar orbital velocity. At least two sets of observations at different positions of the line of apsides are required. The corresponding equations are given.

The Diversity of Cosmic Explosions: Gamma-Ray Bursts and Type Ib/c Supernovae

The death of massive stars and the processes which govern the formation of compact remnants are not fully understood. Observationally, this problem may be addressed by studying different classes of cosmic explosions and their energy sources. Here we discuss recent results on the energetics of gamma-ray bursts (GRBs) and Type Ib/c Supernovae (SNe Ib/c). In particular, radio observations of GRB030329, which allow us to undertake calorimetry of the explosion, reveal that some GRBs are dominated by mildly relativistic ejecta such that the total explosive yield of GRBs is nearly constant, while the ultra-relativistic output varies considerably. On the other hand, SNe Ib/c exhibit a wide diversity in the energy contained in fast ejecta, but none of those observed to date (with the exception of SN1998bw) produced relativistic ejecta. We therefore place a firm limit of 3% on the fraction of SNe Ib/c that could have given rise to a GRB. Thus, there appears to be clear dichotomy between hydrodynamic (SNe) and engine-driven (GRBs) explosions
Landau-Zener-Stuckelberg interferometry in multilevel superconducting flux qubit

Landau-Zener-Stuckelberg interferometry has been extensively investigated in quantum two-level systems, with particular interests on artificial system such as superconducting flux qubits. With increasing the driving field amplitude, more energy levels will be involved into the quantum evolution, which results in population inversion and many interesting interference patterns. These interference patterns can be used to obtain the parameters characterizing the system and probe dephasing mechanisms of the qubit. Most recently, experiments have been extended to the regime with higher-frequency and larger-amplitude driving field, in which the interference pattern exhibited more complicated characteristics. In this article, we give a universal description of the characteristics observed in both low-frequency and high-frequency regimes. Besides explaining the already observed experimental results, our theoretical model predicted many interesting phenomenon, which can be demonstrated by future experiments.
Application of Intelligent Taste Analysis Based on Random Forest Algorithm in Food Quality Inspection

Food safety is a major concern that has an impact on the national economy and people's lives. The food industry has grown in quality and innovation in tandem with the rapid development of the economy and society. The emergence of new food technologies, as well as changes in dietary habits, has increased public concern about food safety. With the emergence of various counterfeit and substandard products, food quality and safety testing have become even more important. Traditional testing methods rely on sensory analysis and physical and chemical analysis. This approach is subjective and poorly adapted to the general public. It requires a high level of technical operation and is difficult to carry out on a large scale. To address this situation, this paper proposes an intelligent approach to food safety quality testing. The core idea is, first, to use sensors to collect data on the various components of the sample to be tested. Second, the random forest (RF) model used in this paper is trained. Third, the trained model is used to classify and identify the test samples. Based on the classification results, a conclusion is drawn as to whether the food product is a variant or a counterfeit. The advantage of this study is that the training model used is a weighted RF algorithm based on mutual information. The correlation between any two decision trees is calculated using mutual information, and for the more correlated decision trees, only the one with the highest evaluation accuracy is retained to form a new RF, and the evaluation accuracy is converted into voting weights, resulting in an RF model with less redundancy and higher evaluation accuracy. The experimental results show that the method used in this paper can successfully identify spoiled or counterfeit products and has good practicality.
Adaptive sliding mode backstepping control for entry reusable launch vehicles based on nonlinear disturbance observer

To attenuate the effects of parameter uncertainties and disturbances on the attitude control performance of entry reusable launch vehicles, an adaptive sliding mode backstepping controller based on nonlinear disturbance observer, here referred to as disturbance observer-based nonlinear controller, is proposed in this paper for the reusable launch vehicles nonlinear and fast time-varying system. The disturbance observer-based nonlinear controller comprises a nonlinear disturbance observer and an adaptive sliding mode backstepping controller with feedforward. First, multiple disturbances resulting from parameter uncertainties, unmodeled dynamics, and environmental disturbances are regarded as an “equivalent” disturbance and can be estimated by the nonlinear disturbance observer. Then, the estimated disturbance can be compensated by the feedforward, and the desired flight attitude can be tracked asymptotically by the adaptive sliding mode backstepping controller. Compared with other reusable launch vehicles flight controllers, the key contributions of the proposed control law are that the controller is independent from the moment of inertia and can achieve a fast convergence rate through an effective compensation for various disturbances. Simulation results of specific reusable launch vehicles demonstrate that the proposed disturbance observer-based nonlinear controller is feasible.
