Theory and Implementation of No-Joint Wire Rope Spatial Geometry Modeling

This paper takes a cross section of 6 × 7 + IWS wire rope as an example to complete the studies on a method of geometric modeling for no-joint wire rope and implementation of a 3D solid model. Frenet–Serret frame theory establishes three types of Frenet–Serret frame, which are double-helix winding straight line, single-helix winding arc, and double-helix winding arc, and it allows derivation of eight types of center line equation of wire. This paper has ascertained tangent condition of center lines of steel wires with the same name between arc and straight-line wire rope and closed condition of no-joint wire rope. It has been concluded that the length of steel wire must be an integer multiple of its lay pitch either in arc wire rope or in straight-line wire rope, and the name of wires in each wire rope must be consistent at the same time. Finally, using Pro/ENGINEER Wildfire 5.0 software generates a 3D solid model of no-joint wire rope.
Numerical study of an electrostatic plasma sheath with non‐thermal electrons and charged nanoparticles

Numerical solutions of the multi‐fluid equations are used to investigate the effects of non‐thermal electrons on the structure of an electrostatic plasma sheath in the presence of nano‐sized dust grains. It is assumed that electrons obey the Cairns distribution [Cairns et al. Geophys. Res. Lett. 22, 2709 (1995)], with a parameter α that determines the effect of non‐thermal electrons and shows the deviation from the Maxwellian distribution. The results revealed that sheath parameters are strongly modified in the presence of non‐thermal electrons and with increasing α the sheath width increases. With the increase in α, the absolute dust charge increases while the dust density is reduced.
Surface Wave Reduction in Antenna Arrays Using Metasurface Inclusion for MIMO and SAR Systems

An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for multiple‐input multiple‐output (MIMO) and synthetic aperture radar (SAR) systems. This is achieved by choking surface current waves induced over the patch antenna by inserting a cross‐shaped metasurface structure between the radiating elements. Each arm of the cross‐shaped structure constituting the metasurface is etched with meander line slot. Effectiveness of the metasurface is demonstrated for a 2 × 2 antenna array that operates over six frequency subbands in X, Ku, and K bands. With the proposed technique, the maximum improvement achieved in attenuating mutual coupling between neighboring antennas is 8.5 dB (8–8.4 GHz), 28 dB (9.6–10.8 GHz), 27 dB (11.7–12.6 GHz), 7.5 dB (13.4–14.2 GHz), 13 dB (16.5–16.8 GHz), and 22.5 dB (18.5–20.3 GHz). Furthermore, with the proposed technique (i) minimum center‐to‐center separation between the radiating elements can be reduced to 0. 26λ0, where λ0 is 8.0 GHz; (ii) use of ground‐plane or defected ground structures are unnecessary; (iii) use of short‐circuited via‐holes are avoided; (iv) it eliminates the issue with poor front‐to‐back ratio; and (v) it can be applied to existing arrays retrospectively.
Drivable Path Planning Using Hybrid Search Algorithm Based on E* and Bernstein–Bézier Motion Primitives

This article proposes a hybrid path-planning algorithm, the HE* algorithm, which combines the discrete grid-based E* search and continuous Bernstein–Bézier (BB) motion primitives. Several researchers have addressed the smooth path planning problem and the sample-based integrated path planning techniques. We believe that the main benefits of the proposed approach are: directly drivable path, no additional post-optimization tasks, reduced search branching, low computational complexity, and completeness guarantee. Several examples and comparisons with the state-of-the-art planners are provided to illustrate and evaluate the main advantages of the HE* algorithm. HE* yields a collision-safe and smooth path that is close to spatially optimal (the Euclidean shortest path) with a guaranteed continuity of curvature. Therefore, the path is easily drivable for a wheeled robot without any additional post-optimization and smoothing required. HE* is a two-stage algorithm which uses a direction-guiding heuristics computed by the E* search in the first stage, which improves the quality and reduces the complexity of the hybrid search in the second stage. In each iteration, the search is expanded by a set of BBs, the parameters of which adapt continuously according to the guiding heuristics. Completeness is guaranteed by relying on a complete node mechanism, which also provides an upper bound for the calculated path cost. A remarkable feature of HE* is that it produces good results even at coarse resolutions.
Estudo de propriedades estruturais e óticas de heteroestruturas formadas com materiais bidimensionais

Nesta tese apresentamos a fabricacao de heteroestruturas formadas a partir de materiais bidimensionais com a finalidade de estudar suas propriedades estruturais e opticas. Os resultados mostram que e possivel integrar materiais bidimensionais em heteroestruturas com interfaces bem definidas. Duas metodologias independentes foram utilizadas. A primeira metodologia consiste no enrolamento de filmes finos para fabricar micro- e nano-tubos de InGaAs/Cr/grafeno. Neste sistema estudamos as interacoes e as propriedades estruturais de mono- e multicamadas de grafeno inseridas em heteroestruturas com simetria cilindrica. Fomos capazes de recuperar os valores para as constantes elasticas do grafeno por meio de um metodo que impoeuma curvatura homogenea e nao-local e mostramos que os efeitos apenas de curvatura nao modificam a assinatura Raman do grafeno ate um limite inferior de raio da ordem de 600 nm. A segunda metodologia utiliza um sistema de transferencia discreta de camadas atomicas de materiais bidimensionais esfoliados micromecanicamente, formando heteroestruturas de Van der Waals (VdW) de grafeno/nitreto de borohexagonal (hBN). Apresentamos um estudo das propriedades opticas destas estruturas com enfase nos efeitos devido a polaritons utilizando a tecnica de espalhamento de infravermelho por microscopia de campo proximo (IR s-SNOM). Ao menos duas classes diferentes de propagacao de polaritons sao conhecidas em sistemas grafeno/hBN: plasmons-polaritons de superficie (SPP ou SP2) no grafeno, efonons-polaritons hiperbolicos (HPP ou HP2) no hBN. Aqui relatamos a observacao de uma hibridizacao destes modos, resultando em modos proprios da heteroestrutura grafeno/hBN. Estes modos serao designados por plasmon-fonons polaritons de superficie (SPPP) e sao produzidos por oscilacoes coerentes da densidade de eletrons no grafeno e vibracoes da rede do hBN.
Extended adaptive optimal control of linear systems with unknown dynamics using adaptive dynamic programming

The extended infinite horizon optimal control problem of continuous time linear systems with unknown dynamics is investigated in this paper. This optimal control problem can be solved using the corresponding extended algebraic Riccati equation. A new policy iteration algorithm is proposed to approximate the solution of the extended algebraic Riccati equation when the system dynamics are known. The convergence of the proposed algorithm is proved. Based on the proposed policy iteration algorithm, an online adaptive dynamic programming (ADP) algorithm is developed to find the solution to the extended infinite horizon optimal control problem of unknown continuous time linear systems. The convergence of the online ADP algorithm is analyzed. Finally, two simulation examples are given to demonstrate the effectiveness of the developed online ADP algorithm.
Event-Triggered Dynamic Output Feedback Control for Switched Systems With Frequent Asynchronism

This paper addresses the event-triggered dynamic output feedback control for switched linear systems with frequent asynchronism. Different from existing work, which limits at most once switching during an interevent interval, we adopt the average dwell time approach without limiting the minimum dwell time of each subsystem, and thus frequent switching is allowed to happen in an interevent interval. Since the difficulty in acquiring the full information of system states, the dynamic output feedback controller is taken into account to stabilize the switched system. By employing a controller-mode-dependent Lyapunov functional, stability criterion is proposed for the resulting closed-loop system, based on which the dynamic output feedback controller together with the mode-dependent event-triggered mechanism is codesigned. Besides, the existence of the lower bound on interevent intervals is attentively discussed, which gets rid of the Zeno behavior. Finally, the effectiveness of the proposed method is illustrated by numerical simulations.
Non-linearity between inflation and economic growth: What lessons for the BEAC Zone?

The purpose of this paper is to estimate the optimal inflation rate, defined as the threshold level below and above which inflation affects economic growth, from the experience of the BEAC1. For this purpose, we use panel data over the period 1985-2013. Relying upon the estimation of Panel Smooth Transition Regression (PSTR) model inspired from Gonzalez et al. (2005), our main findings are the following. (i) The optimal inflation rate is around 4.3%. (ii) Below the threshold, an increase of 1% of inflation enhances growth by 0.28 %. Over the threshold, a one percent increase in inflation leads to a reduction of 0.26% in growth. These results are robust with respect to sensitivity analyses and GMM estimation.JEL Codes: E31, C23.
Extended Anisotropic Diffusion Profiles in GPU for Hyperspectral Imagery

Morphological profiles are a common approach for extracting spatial information from remote sensing hyperspectral images by extracting structural features. Other profiles can be built based on different approaches such as, for example, differential morphological profiles, or attribute profiles. Another technique used for characterizing spatial information on the images at different scales is based on computing profiles relying on edge-preserving filters such as anisotropic diffusion filters. Their main advantage is the preservation of the distinctive morphological features of the images at the cost of an iterative calculation. In this article, the high computational cost associated with the construction of anisotropic diffusion profiles (ADPs) is highly reduced. In particular, we propose a low-cost computational approach for computing ADPs on Nvidia GPUs as well as a detailed characterization of the method, comparing it in terms of accuracy and structural similarity to other existing alternatives.

Febrile Neutropenia Associated with Painful Lesions of the Palms and Digits

A 47-year-old African American woman with a history of multiple myeloma was admitted to the hospital to undergo allogeneic stem cell transplantation. At admission to the hospital, the patient underwent conditioning total body irradiation and then received high-dose melphalan. On the day before she underwent transplantation, the patient developed a temperature >38.6? C. At the time, the findings of her physical examination were unremarkable except for moderate mucositis. The patient was treated with empirical piperacillin-tazobactam and vancomycin. Despite this treatment, she continued to have daily fevers, and after 2 days, voriconazole was added to the patient's regimen. The patient was neutropenic throughout this time. On day 7 after admission to the hospital, the patient developed exquisitely tender lesions on the palms of both hands and on her second and third digits. These lesions were purplish
Evaluating the effect of temperature on flower and boll opening density for selection of climate resilient cultivars in cotton

Climate change is a great challenge that badly affects the agricultural economy all over the world. Studies on evaluating the effect of temperature on flower, boll opening density for selection of climate resilient cultivars in cotton were conducted for two crop seasons during 2016 and 2017. FH-Lalazar, FH-Kahkashan, FHNoor, FH-326 and MNH-992 cultivars were used for experimentation following randomized complete block design with three replications. Temperature during 2016 was higher than 2017 that badly affected the flower and boll opening density. On the basis of fruiting behaviour FH-Noor and MNH-992 were early maturing as compared with FH-326. Cluster analysis exhibited that cluster-2 consisted of three months i.e., July, August and September. Maximum flowers on all cultivars were observed during these three months contributing maximum yield. Principal component analysis results demonstrated that first two Principal components having Eigen values ≥1 induced accumulative 90.7% variations. The variability was mainly due to minimum and maximum temperature. In fact, we could state that based on the correlation of 0.647% variation of this, principal component is primarily a measure of the minimum temperature. It was concluded that reproductive stage of cotton is very sensitive to increasing temperature and cultivation of FH-326 that will be very useful in the changing climate.

OBJECTIVE: To explore the expressions and clinical significance of serum vascular endothelial growth factor(VEGF),tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) in multiple myeloma(MM) patients with thalidomide and VAD chemotherapy.METHODS: Totally 46 patients were divided into two groups randomly,T-VAD and VAD.Twenty-three patients received six courses VAD chemotherapy and thalidomide 200-250 mg/d was taken orally every day.The other group received six VAD chemotherapy only.The expressions of VEGF,TNF-α and IL-6 were examined by ELISA before and after treatment,and compared with 26 normal persons as control group.RESULTS: Both the expressions of VEGF,TNF-α and IL-6 were higher compared with normal persons before treatment.There were significant differences between treatment groups and controls(P0.01),but no significant difference was detected between both treatment groups(P0.05). And after treatment,the difference was statistically different in the expressions of VEGF,TNF-α and IL-6 between two treatment groups(P0.05),while the data of group T-VAD was significantly decreased than the other.But both had statistically difference before and after treatment(P0.05). The total effective rate was higher in group T-VAD(P0.05). CONCLUSIONS: The expressions of VEGF,TNF-α and IL-6 are much higher in the patients with MM than in the healthy people.The total effective rate after treatment is higher in group T-VAD than VAD,and the expressions of VEGF,TNF-α and IL-6 were significantly decreased,which is clinically important for improving the prognosis of patients with MM.
Etude de l’impact du renforcemen t de la couche de forme dans les chaussées par des biomatériaux – fibre de Dattier

In order to contribute to the reduction of construction costs, the preservation of the environment and the assurance of a good sustainability of road projects, the idea of the reuse of mediocre soils for the realization of road surface layers becomes a necessity, on the other hand the strengthening of the soil by ecological materials of local origin is an optimal solution. Palm leaf fibers (Dattier) have been used to improve the mechanical characteristics of this type of soil. The main objective of this work is the study of the effect of the Dattier palm fiber content at different percentages (3%, 5%, and 7%) on the mechanical characteristics of a soil sample taken from a tree. site located in the municipality of Tidjellabine wilaya de Boumerdes. The results obtained show that the mechanical behavior improves each time the percentage of the addition of fiber is increased for all the tests carried out.
2D flat Luneburg lens antenna for multibeam scanning application

A two-dimensional (2D) flat Luneburg lens antenna (LLA) operating at Ka-band is presented in this Letter. Based on the transformation optics, the 2D conventional Luneburg lens is compressed to the flat form. The proposed flat LLA is composed of six discretised dielectric layers with different permittivity, two metallic parallel plates and an E-shaped microstrip patch antenna array. By switching on/off the array elements, the lens antenna is able to achieve 1D beam-scanning with a scan coverage of ±30° at 28 GHz. The proposed lens antenna has a low profile of 7 mm, a focus-to-diameter ratio of 0.42, and the simulated/measured aperture efficiency for the on-axis beam is 56.8/36% at 28 GHz. The proposed 2D flat LLA is highly suitable for 5G mm-wave wireless communication with the advantages of low profile, wide beam-scanning range, low cost, and easy fabrication.
NON-INFORMATIVE BAYESIAN INFERENCE FOR HETEROGENEITY IN A GENERALIZED MARGINAL RANDOM EFFECTS META-ANALYSIS

In this paper an objective Bayesian inference is proposed for the heterogeneity parameter in a generalized marginal random effects model. Models of this kind are widely used in meta-analysis and in inter-laboratory comparisons. Under the assumption of elliptically contoured distributions, a reference prior for the model parameters is obtained and the analytical expression of the corresponding posterior is derived. We also state necessary conditions for the resulting posterior to be proper and for the existence of its first two moments. The obtained general theoretical results are illustrated for three popular families of elliptically contoured distributions: normal distribution, t-distribution, and Laplace distribution.
Critical L-values of Primitive Forms Twisted by Dirichlet Characters

Let f be a primitive form of weight k > 1 with nebentypus e and χ be a primitive Dirichlet character. Then, we consider the twist of f by χ and its Dirichlet L-series denoted by L(f, s, χ). Those central L-values (or even vanishings and nonvanishings of them) are believed to encode important arithmetic invariants of algebraic objects over various fields. In this thesis, we mainly study vanishings and nonvanishings of the central Lvalues of primitive form f of weight k ≥ 2 twisted by χ of a prime order l. More precisely, firstly, assume that k > 2, 2 | k and l > 2. Then, as a generalisation of the nonvanishing theorem for k = 2 of Fearnley, Kisilevsky and Kuwata, for the case that L(f, k/2) 6= 0 we prove that for all but finitely many primes l there exist infinitely many of twists of order l such that L(f, k/2, χ) 6= 0. We also present numerical results on vanishings of twists of l = 3, 5, and 7 for some primitive forms of k > 2, and based on the random matrix theory, make a conjecture that for a primitive form of even weight k > 2, there exist only a finite number of vanishings of twists of order l > 2. Secondly, assume that k = 2 and l = 3. Then, inspired by the work of Fiorilli for quadratic twists, we estimate the average analytic rank of twists for the group family under some hypotheses including the generalised Riemann hypothesis, which implies that there exist infinitely many cubic twists such that L(f, 1, χ) 6= 0. Lastly, consider quadratic twists of an elliptic curve E over Q of conductor N associated with quadratic characters χd of fundamental discriminants d with a prime |d|. Then, by controlling 2-Selmer groups of E and its quadratic twist by χd using the method of Mazur and Rubin, we show that for some E satisfying some conditions there exist a set of residue classes |d| mod N such that L(E, 1, χd) 6= 0 under the Birch and Swinnerton-Dyer conjecture.

Cálculo por primeros principios del coeficiente de difusión del H en una red de Fe pura

La fragilizacion por hidrogeno es una de las principales causas de fallo de los aceros de alta resistencia basados en hierro BCC. Debido a su importancia tecnologica, se han realizado numerosos estudios sobre el transporte de hidrogeno en la red de hierro. Sin embargo, los datos experimentales y los calculos teoricos muestran una gran dispersion debida a los diferentes metodos de ensayo, los defectos inherentes del material (vacantes, dislocaciones o bordes de grano) y las diferentes aproximaciones teoricas. Utilizando una teoria de primeros principios hemos calculado el espectro de vibraciones (fonones) de una red de hierro BCC en presencia de hidrogeno intersticial para obtener la energia libre de Helmholtz, F. Se han encontrado diferencias significativas entre el regimen de alta (Fe:H = 1:1) y de baja concentracion (Fe:H = 16:1), en particular una ocupacion diferente de los intersticiales en huecos octaedricos y tetraedricos. Aplicando la ley de las mezclas para estas poblaciones y utilizando la dependencia de F con la temperatura hemos estimado la dependencia del coeficiente de difusion de Hidrogeno con la temperatura. La comparacion con los datos experimentales seleccionados por Kiuchi y McLellan (Acta Metal. 31, 961) es satisfactoria y refrenda el metodo teorico utilizado.
