Four different operating points describing four different local linear state models are used in obtaining the TS fuzzy model, state estimation based on Ackermann's principle was used to determine the state feedback matrix for the four selected operating points, the system in open loop and in closed loop is simulated at varying parameter conditions. Results indicating effectiveness of the developed controller over other reported control method are generated.
Morphometric studies of the tropical leatherleaf slug Laevicaulis alte from prachi belt of Odisha

The present study emphasizes the morphometric studies on a tropical leatherleaf slug Laevicaulis alte (Class: Gastropoda, Order: Systellommatophora, Family: Veronicellidae) recovered from Prachi belt of Odisha at Adaspur, Cuttack. The specimens (N=18) were collected from the college garden and traditional morphometric analysis was conducted in the laboratory. A significant positive correlation was obtained between the biological parameters like length-live weight (0.943), length-circumference (0.898), circumference-live weight (0.823). Considering these three sets of morphometric variables in the species i.e; live weight and length, length-circumference, live weight-circumference fitted regression equations were also developed like (Y= 0.998x – 2.307, R2 = 0.888), (Y= 0.607x + 0.017, R2 = 0.806), (Y= 0.536x + 1.671, R2 = 0.678) respectively.
Protection of Logical Qubits via Optimal State Transfers

Dynamical decoupling can enforce a symmetry on the dynamics of an open quantum system. Here we develop an efficient dynamical-decoupling-based strategy to create the decoherence-free subspaces (DFSs) for a set of qubits by optimally transferring the states of these qubits. We design to transfer the state of each qubit to all of the other qubits in an optimal and efficient manner, so as to produce an effective collective-type noise for all qubits. This collective pseudo-noise is essentially derived from arbitrarily independent real baths and needs only nearest-neighbor state transfers for its implementation. Moreover, our scheme requires only N steps to produce the effective collective-type noise for a system of N qubits. It provides an experimentally feasible and efficient approach to achieving the DFSs for encoding the protected logical qubits.
Response surface methodology (RSM) for optimization of chalcopyrite concentrate leaching with silver-coated pyrite

This study aims to leach copper from chalcopyrite and optimizing the leaching process, using the response surface methodology (RSM). The RSM, a D-optimal design with four factors in three levels was employed to evaluate the effect of particle size, temperature, silver-coated pyrite to chalcopyrite ratio and redox potential parameters on the copper extraction efficiency. A quadratic model was then proposed by the RSM to correlate leaching variables. The tests results indicated that the model was significant with the experimental data at a correlation coefficient (R) of 0.96. The most important parameters of copper extraction efficiency were particle size and silver-coated pyrite-to-chalcopyrite ratio, and also the squared term of particle size (A), temperature (B) and redox potential (D). In addition, the interaction between redox potential and silver-coated pyrite-to-chalcopyrite ratio (CD) was significant. It was shown that the finer the particle size the faster the leaching rate of copper. It was also indicated that by increasing silvercoated pyrite to chalcopyrite ratio of 6:1 copper recovery increased. The maximum recovery of copper (71%) was obtained for the particle size of -38 μm, 70 °C, 420 mV of redox potential, silver-coated pyrite-to-chalcopyrite ratio of 6 and leaching time of 8 hours.
Analysis of Oropharyngeal Microbiota between the Patients with Bronchial Asthma and the Non-Asthmatic Persons

Bronchial asthma can be triggered by microbial agents in the oropharynx. This study was designed to identify the differences in microbiota of oropharynx of bronchial asthmatic patients in contrast to normal controls. In order to resolve the qualitative and quantitative diversity of the 16S rRNA gene present in the oropharynx microbiota of 4 patients and 4 controls, we compared microbial communities using Sanger sequencing and 376 sequences of 16S rRNA gene were analyzed. Of the total microbial diversity detected in the oropharynx in asthmatic patients 45.6% comprised members of the Firmicutes. In contrast, Proteobacteria (44.0%) dominated the oropharyngeal microbiota in the normal control group. Members of the Bacteroidetes, Fusobacteria, Actinobacteria, TM7, Cyanobacteria and unclassified bacteria were present in both groups. In conclusion, the difference in the microbiota of the oropharynx between patients and normal individuals could trigger symptomatic attacks in bronchial asthma.
Examining the consistency of mastery and performance goals across group and perceived-ability contexts

We report a series of three studies investigating the consistency of 8to 10-year-olds’ achievement goal orientation across different learning contexts. Our main aim was to examine whether goal orientations represent stable individual differences towards learning or vary according to context. To achieve this we examined the influence of two variables on the consistency of children’s achievement goal adoption: (a) learning activities which varied in levels of peer interaction (individual, collaborative, and whole-class) and (b) children’s perceptions of their ability in these contexts (high or low). We developed a method of measuring achievement goals in each of these contexts by presenting children with situationspecific scenarios in which they selected a response from a choice of either masteryor performance-oriented behaviour. We then examined achievement goal preferences within each context and the consistency of goal responses across contexts. Results suggest that for some children achievement goal orientation is consistent across contexts and appears to be dispositional. However, most children adopted different goals according to context. Also, specific interactive contexts exerted particularly strong influences on achievement goal preferences both within and between the three samples. Implications for a theoretical understanding of achievement goals as both situationally specific and dispositional are discussed.
Tetra Primer ARMS PCR Optimization to Detect Single Nucleotide Polymorphism of the KLF14 Gene

GWAS (genome-wide association studies) have associated Type 2 Diabetes Mellitus with the single nucleotide polymorphism (SNPs) rs972283 (A/G) of KLF14 gene with in a global population. The most common techniques used to analyze SNPs are time consuming, multi-step process and require expensive instruments. Therefore, in order to overcome these problems, we have developed a new, rapid and cost effective T-ARMS PCR assay to genotype rs972283. However, the optimization step can be hardworking and laborious. Hence, we propose to demonstrate and discuss critical steps for its development, in a way to provide useful information. In a first step, we design and validate two specific primer pair for T-ARMS PCR. Later, the amplification conditions were optimized for DNA concentration, annealing temperature, Taq DNA polymerase units and primers concentration. The last one was considered the main interference factor for a correct amplification and appropriate band intensity. Finally, the results obtained by T-ARMS PCR were concordant with sequencing. T-ARMS PCR assay developed in our laboratory for genotyping rs972283 (A/G) of KLF14 gene is time saving and cost-effective compared to the available methods used for SNP studies.
A Local Time-Stepping Method for Multiphase Flow in Porous Media

Simulation of multiphase flow in natural subsurface formations include selection of time-step size, i.e., the discrete snapshots (steps) over which the time-dependent nonlinear process is investigated. The simulation results would naturally depend on the size of the discrete time step, according to the order of accuracy of the implemented numerical scheme. For accurate analyses the required time steps might be needed to be very small, which then leads to very costly simulations, which are often times impractical in real-world simulation applications. Taking coarse-scale time-step sizes can reduce the computational costs, however, it results in lower simulation accuracy. Note that a common simulation practice is to take constant time-step everywhere in the computational domain. To resolve this challenge, this MSc thesis report presents a novel local time-stepping (LTS) method for multiphase flow in porous media. In this method, different time-steps can be applied in one computational domain; allowing for employing small time steps in sub-domains with higher sensitivity to the time step size and bigger time steps elsewhere. The LTS method is developed for all types of sequentially-coupled and fully-coupled simulation strategies. For all of these developments, the interfacial flux continuity is the key requirement to connect the sub-domains of different time zones. The fluxes chosen for the inner stages of the coarse time-step are consistent with the chosen simulation strategy. More precisely, in the case of the implicit-pressure-explicit-saturation (IMPES) method these fluxes are lagged in time (explicit), while for the sequential implicit and fully implicit (FIM) methods they are calculated at the current (implicit) time-step. For implicit transport method, the refined zone partition matrices are developed to algebraically form the refined zone Jacobian matrix and refined zone residual vector. The numerical results show that only a fraction of the domain can be simulated with small time steps; while the rest can be simulated at a bigger one. Local time-stepping method provides accurate simulation results compared with the fine-scale time-step simulation results for all three simulation strategies. Specially, the local time-stepping for FIM simulations, which is the mostly common commercial-grade simulation approach, can preserve the accuracy of the results and also the computational efficiency. For the studied cases, the computational efficiency gain of LTS for sequential implicit method is not as significant as that of the FIM. To exploit full adaptivity in simulation, as presented in Appendix B, one can directly apply the developed method of this thesis to adaptive implicit method (AIM); where sequential and fully implicit coupling approaches are applied in different sub-domains of the reservoir. Overall, LTS casts a promising approach to optimize accuracy-efficiency tradeoff when it comes to time step selection.
The Effect of Color on Personality Traits

Research has shown correlations between color preference and psychiatric disorders, drug and alcohol addicts, and changes in preference in age progression. However, there is a shortage of research on the effect of color on personality assessment. College students were administered the Big Five personality test on one of two different colors of paper (red or blue). Although it was expected that red would increase extroversion scores and that blue would decrease extroversion scores, results showed no differences between groups.
A Graph Model of Alignment in Multilog

Justified by empirical-driven reasoning, this papers extends a graph-theoretical model of lexical alignment in dialog towards an initial conceptual model for alignment in multilog (three-and-more speaker discourse). Underway, the monotonic increasing alignment function is counterbalanced by an unlearning function which allows for capturing the drifting apart of language use. Thus, the paper contributes to alignment in communication in two respects: (i) by acknowledging “anti-alignment” alongside with the common notions of similarity or repetition, and (ii) by providing a theoretical starting point for quantifying alignment in multilog.

THE EFFECT OF OBJECT SURFACE COLORS ON TERRESTRIAL LASER SCANNERS

The terrestrial laser scanning systems are a relatively new measurement technology. Along with technological advances, these systems are gaining popularity and have been increasingly used in many different fields. With terrestrial laser scanning technology, three- dimensional (3D) information and images of objects can be obtained more practical, easy and with high accuracy compared to conventional methods. Additionally, measurement of an object is performed without being in physical contact. In this study, our test area 2.10m×2.80m in vertical position was scanned at 35 m distance in different object colors (white, red, blue and green) with Topcon laser scanner and laser scanner’s position accuracy according to this colors were investigated. By switching Y and Z coordinates obtained from laser scanning, test area was changed to horizontal position. In this case, expected a half rectangular prism’ volume and volumes obtained from laser scanning were calculated. Based on our volume differences evaluation results, it was found that within scanning 35meters distance, position accuracy of this laser scanner is between 5.7 mm and 12.2 mm. In addition, the best result is obtained by scanning the test area in white color.
Classical and Fractional-Order Analysis of the Free and Forced Double Pendulum

This paper presents the fractional-order dynamics of the double pendulum by means of fractional-order modeling. Equations of motion have been derived for cases with and without external forcing. Generalized force terms have been obtained for five different cases of forcing. Both integer and fractional-order analysis have been carried out. Phase diagrams have been plotted to visualize the effect of fractional order approach. The originality of this work arises from the fact that the double pendulum has been modeled with the fractional dynamics approach. The governing equations of motion of the system have been obtained through fractional variational principles.
3d Scanning and Replication for Museum and Cultural Heritage Applications

Abstract The recent proliferation of commercial three-dimensional digital scanning devices has made 3D scanning, and virtual and physical replication, a practical reality in the field of heritage preservation. 3D scanning produces a high-precision digital reference document that records condition, provides a virtual model for replication, and makes possible easy mass distribution of digital data. In addition to research, documentation, and replication, 3D data of artifacts are increasingly being used for museum collections storage and packing designs. The cost and complexity of 3D imaging technologies have made 3D scanning impractical for many heritage institutions in the past, but this is changing, as an increasing number of commercial systems are being tailored and marketed for heritage applications. This paper presents a review of the current state of 3D imaging in the cultural heritage field, methods of physical replication, the different systems used in heritage applications, criteria for choosing a system, and the techniques used for working with the data. Attention is given to identifying those objects that are not likely to be suited for 3D scanning.
EVALUATION OF ACCURACY OF DEMS OBTAINED FROM UAV-POINT CLOUDS FOR DIFFERENT TOPOGRAPHICAL AREAS

The main objective of the study was to examine accuracies of DEMs (Digital Elevation Models) with different topographical structures generated by using the Unmanned Aerial Vehicle (UAV) point clouds. Two different terrains with flat and sloping topographical structures were selected for the study, and DEMs of these terrains were generated using eight interpolation techniques (Kriging, Natural Neighbor, Radial Basis Function Triangulation with Linear interpolation, Nearest Neighbor, Invers Distance to a Power, Local Polynomial and Minimum Curvature). The accuracies of DEMs were tested by calculating the statistic methods with the help of the control points obtained by land surveying techniques. At the end of the study, it was observed that in DEMs prepared for both flat (study area 1) and sloping (study area 2) terrains, Kriging interpolation method yields the best results as study area 1 and 2, respectively. In addition, the results were examined using Shapiro-Wilk and ANOVA:Friedman tests. After observing with the Shapiro-Wilk test that the data has a normal distribution, it was statistically determined through the parametric ANOVA: Friedman test that there is no difference between the variables.
Classical and snapshot forms of the POD technique applied to a helical vortex filament

Low-dimensional characteristics of a helical vortex filament from a reduced-scale rotor are investigated using proper orthogonal decomposition (POD). Measurements are captured by way of particle image velocimetry. Experiments are performed on a 1.0 m diameter, single-bladed rotor in hover. The rotor is operated at 1500 RPM, which corresponds to a blade tip chord Reynolds number of 218,000 and a tip Mach number of 0.23. The blade is set to a collective pitch angle of 7.3◦, which resulted in a blade loading (CT /σ ) of 0.066. Classical and snapshot techniques of POD are applied to a helical vortex filament, both of which revealed similar characteristics of the dominant modes. Two different techniques (Γ1 and geometric center methods) of wander correction are applied to test the sensitivity of the low-dimensional characteristics using POD. Using the Γ1 method, POD revealed that an elliptic instability dominated the energy spectrum of the velocity fluctuations within the tip vortex. However, at early vortex ages an axisymmetric mode, which is found to perform vortex roll-up, is found to be equally dominant. Further, the spatial structures of the most energetic modes derived from POD are found to be sensitive to the choice of the centering technique used.

Targeted Estimation of Variable Importance Measures with Interval-Censored Outcomes

In most experimental and observational studies, participants are not followed in continuous time. Instead, data is collected about participants only at certain monitoring times. These monitoring times are random, and often participant specific. As a result, outcomes are only known up to random time intervals, resulting in interval-censored data. In contrast, when estimating variable importance measures on interval-censored outcomes, practitioners often ignore the presence of interval-censoring, and instead treat the data as continuous or right-censored, applying ad-hoc approaches to mask the true interval-censoring. In this paper, we describe Targeted Minimum Loss-based Estimation methods tailored for estimation of variable importance measures with interval-censored outcomes. We demonstrate the performance of the interval-censored TMLE procedure through simulation studies, and apply the method to analyze the effects of a variety of variables on spontaneous hepatitis C virus clearance among injection drug users, using data from the “International Collaboration of Incident HIV and HCV in Injecting Cohorts” project.
Application-Layer DDOS Detection Based on a One-Class Support Vector Machine

Application-layer Distributed Denial-of-Service (DDoS) attack takes advantage of the complexity and diversity of network protocols and services. This kind of attacks is more difficult to prevent than other kinds of DDoS attacks. This paper introduces a novel detection mechanism for application-layer DDoS attack based on a One-Class Support Vector Machine (OC-SVM). Support vector machine (SVM) is a relatively new machine learning technique based on statistics. OC-SVM is a special variant of the SVM and since only the normal data is required for training, it is effective for detection of application-layer DDoS attack. In this detection strategy, we first extract 7 features from normal users’ sessions. Then, we build normal users’ browsing models by using OC-SVM. Finally, we use these models to detect application-layer DDoS attacks. Numerical results based on simulation experiments demonstrate the efficacy of our detection method.
Hartite from Bilina

In the Bilina Mine (Czech Republic), a very chemically pure material corresponding to hartite was found as a product of distillation into the pelosiderite nodule during coalification of a lignite seam in the Miocene or later. The amount of the material available allowed characterizing this natural mineral equivalent of the hydrocarbon (+)-phyllocladane [ 16ct(H)-phyllocladane] thoroughly. Elementary analysis of hartite from Bflina gave C :87.45 wt%o andH: 12.55 wt%o, which corresponds to the formula CroH.o. The IR spectrum demonstrated the presence of gem-dimethyl groups (doublet E"CH, at 1369 and 1383 cm '). Other bands indicated the presence of methyl and methylene groups. NMR studies showed that the hydrocarbon (hatite) molecule contains four CH. groups, nine CH, groups, four CH groups, and three quaternary carbon atoms. The sample exhibits a well-defined melting point between 71 and 71.5 "C. Measurements of optical rotation gave [ct]o: +24.2 (CHCI., c : 0.7). Lattice parameters from single-crystal study measured at 293(2) K were a : 11.401 (l), b = 20.952 (2), c : 7.4060 (8) A. ct : 93.941 (9)', p : 100.750 (8)', and 1 : 80.499 (9)'. The crystal system is triclinic with space group Pl, Z : 4, V : 1113.8 (3) A. Densities arc D^ : I.O4 g/cm3 and D, = 1.064 g/cm3, respectively. Isotopic composition of C in hartite from Bflina gave D'3Crpoer : -24.4(l) %o, d cornmon value for coal and organic sedimentary material derived from higher plants.
