Abstract:
This article considers the problem of finding a shortest tour to visit viewing sets of points on a plane. Each viewing set is represented as an inverted view cone with apex angle [Formula: see text] and height [Formula: see text]. The apex of each cone is restricted to lie on the ground plane. Its orientation angle (tilt) [Formula: see text] is the angle difference between the cone bisector and the ground plane normal. This is a novel variant of the 3D Traveling Salesman Problem with Neighborhoods (TSPN) called Cone-TSPN. One application of Cone-TSPN is to compute a trajectory to observe a given set of locations with a camera: for each location, we can generate a set of cones whose apex and orientation angles [Formula: see text] and [Formula: see text] correspond to the camera’s field of view and tilt. The height of each cone [Formula: see text] corresponds to the desired resolution. Recently, Plonski and Isler presented an approximation algorithm for Cone-TSPN for the case where all cones have a uniform orientation angle of [Formula: see text]. We study a new variant of Cone-TSPN where we relax this constraint and allow the cones to have non-uniform orientations. We call this problem Tilted Cone-TSPN and present a polynomial-time approximation algorithm with ratio [Formula: see text], where [Formula: see text] is the set of all cone heights. We demonstrate through simulations that our algorithm can be implemented in a practical way and that by exploiting the structure of the cones we can achieve shorter tours. Finally, we present experimental results from various agriculture applications that show the benefit of considering view angles for path planning.

Abstract:
Forward blowing from a pair of plasma actuators on the leeward surface and near the apex is used to switch the asymmetric vortex pair over a cone of semi-apex angle 10° at high angles of attack. Wind tunnel pressure measurements show that by appropriate design of the actuators and appropriate choice of the AC voltage and frequency, side forces and yawing moments of opposite signs can be obtained at a given angle of attack by activating one of the plasma actuators. Further work is suggested.

Abstract:
A form of turbostratic boron nitride containing a large percentage of micrometre-size conically shaped particles was investigated by transmission electron microscopy. Electron diffraction patterns revealed the presence of correlations between adjacent boron nitride layers. The diffraction patterns were also used to determine the cone apex angle of many cone-like objects. The apex angles exhibited a broad distribution from 84 to 130° with an ill defined peak in the 92–95° region. These results could be accounted for by a structure model in which conical boron nitride layers are helically wound about a disclination axis, according to overlap angles that correspond to high densities of coincidental lattice sites between successive layers. The clustering of the apex angles near 93° was attributed to the formation of a square ring during the nucleation stage. This appears to be specific to the boron nitride system.

Abstract:
Abstract To explore the thermal elastohydrodynamic lubrication performance of rolling cone enveloping end face worm drive, the mathematical model of thermal elastohydrodynamic lubrication is established based on the meshing theory of rolling cone enveloping end face worm drive and elastohydrodynamic lubrication theory. With the help of the numerical analysis software MATLAB, the thermal elastohydrodynamic lubrication performance under smooth conditions is selectively analyzed by the multigrid method. Besides, the effects of throat coefficient, cone apex radius and half cone angle of the rolling cone on thermal elastohydrodynamic lubrication performance are analyzed at the meshing out of the transmission pair. The results show that the thermal elastohydrodynamic lubrication film thickness at meshing out of the worm gear is the smallest; the oil film thickness, oil film pressure and oil film temperature are reduced from meshing in to meshing out. The oil film temperature at the interlayer is the largest. The oil film temperature at the end face worm surface is the smallest. The small half-cone angle of the cone apex radius and larger throat coefficient and cone apex radius may achieve better thermal elastohydrodynamic lubrication performance of rolling cone enveloping end face worm drive.

A pair of plasma actuators with horseshoe shape is proposed for dynamic manipulation of forebody aerodynamic load at high angles of attack. Preliminary wind tunnel pressure measurements show that asymmetric force over a conical forebody with semi-apex angle 10° can be manipulated by activating the plasma actuator mounted on one side of the cone tip.

Abstract:
We developed a method to fabricate bent fiber probe: heated pulling combined with chemical etching. Based on sampling theory, the resolving power of SNOM relates to the size of the probe tip. If the apex of the probe is smaller, the resolution ability of SNOM is higher. At the same time it can collect more near-field information through bigger cone angle of probe. Through improving the operation and optimizing the parameters of the heated-pulling instrument, we can obtain the probe with bent angle fiber varying from 120-150 degree, the cone angle varying from 40-90 degree and the apex diameter less than 100nm. With this new brush shape of probe, the collecting efficiency for near-field light is improved. That is to say that more near-field information is obtained. The successful ratio of the produce is more than 70%.

Abstract:
Abstract This study presents the effect of the 3 apex angles of cone and water levels on the bearing capacity of silty sandy soil (SM) layer by interpreting results from Kunzelstab test. The SM soil layer was prepared in the testing tank and it was used as the representative of sandy soil for some area in Thailand. As the results, the cone angle increase, a number of blows increase and the adjusted factors of the blows from the apex angles of 60° and 180 º to be that of the apex angle of 90º (control) were 1.118 and 0.878, respectively. The obtained correlation between the blows and the internal friction angles of SM soil can be used for calculating the soil bearing capacity which lowers the ground surface of 0.6 m. The soil bearing capacity of SM soil below ground water level decreases 70 to 75 percent (average values from testing results) comparing to that of dry soil. Moreover, the bearing capacity of SM soil above the water level up to 0.6 m decreases 25 to 30 percent (average values from testing results) comparing to that of dry soil at the same depth. Silty sandy soil layer was found determined to have lower bearing capacity due to higher ground water level. Therefore, the calculation of the soil bearing capacity in silty sandy soil layer should be considered the effect of ground water level.

Abstract:
The accuracy and stability of circular conical surface is easily influenced by the different distribution of noise and points in point cloud, when 3D point cloud data fits conical surface. For this reason, this paper proposes a novel method of establishing and optimizing the objective function with conical vertex. First, calculate the axis direction and half-apex angle of the cone; second, calculate conical vertex according to the result got in the first step; third, establish objective function with axis direction and half-apex angle and vertex, and optimize it with Levenberg-Marquardt. The method’s feasibility and robustness are verified by simulating and real experiments. The proposed algorithm has been successfully applied to a self-development 3D measuring system (TN 3DOMS) of Mianyang Saint Buffalo Technologies Limited Company.

Abstract:
A novel beam demagnifier(a cone) is presented based on total internal reflection-refraction principle, and the light propagation characteristics inside the cone were studied by using ray-tracing method and computer simulation. This paper presents several proof-theoretic results concerning a cone as a beam demagnifier under certain conditions. When the semiapex angle of the cone is equal to a series of specific values an output beam is parallel to an incident beam, the beam's diameter narrows, and the demagnification ratio of the cone is a function of apex angle and there exists a series of extreme points; the demagnifier can be used in series so as to further narrow or magnify the diameter of incident beam.

Full text
Abstract:
An experimental investigation was performed to ascertain the nature of turbulence in a narrow apex angle isosceles triangular duct. The study involved the design and construction of a low noise, low turbulence wind tunnel that had an isosceles triangular test section with an apex angle of 11.5[degrees]. Experiments involved the measurement of velocity fluctuations using hot wire anemometry and wall pressure fluctuations using a condenser microphone. Measurement of the velocity fluctuations reconfirms the coexistence of laminar and turbulent regions at a given cross section for a range of Reynolds numbers. The laminar region is concentrated closer to the apex while the turbulent region is found closer to the base. The point of transition is a function of the Reynolds number and moves closer to the apex as the flow rate is increased. Moreover, it was found in this investigation that traditional scaling of the turbulent statistical quantities do not hold good in this geometry. Although velocity fluctuations showed distinctive flow regimes, no such distinction could be seen in the dynamic wall pressure data. The nature of the dynamic wall pressure was uniform throughout the entire cross section suggesting that wall pressure fluctuations, unlike the velocity fluctuations, are able to travel from the base to the apex, without being damped. This implies that the relationship between the velocity and the pressure fluctuations applicable in the other systems does not hold well in a narrow apex angle isosceles triangular duct. Further, the typical scaling relationships applied to wall pressure spectra of other geometries doesn't apply in this scenario and the ratio of the RMS pressure fluctuation to the mean shear is much higher compared to a flat plate or pipe flow situation.

Abstract:
An empirical approach to the study of phosphine compounds was completed using Molecular Mechanics 2 (MM2), and several computer programs written to descibe and analyze the final geometric orientations of the molecules. The calculations were performed on 64 conformers of 16 different phosphines. Results from these calculations were compared to those previously obtained for MNDO and MINDO/3 calculations, and to experimental data. Cone angles calculated from the MM2 optimized geometries, were compared to Tolman's original work, and to values obtained from semiempirical calculations, and to experimental results. In general, it was found that weighted average cone angles best represent the size of phosphine ligands.

There is a paucity of studies that make use of the alpha angle as a diagnostic tool to assist with the interceptive treatment, prognosis, treatment duration and surgical outcome of possible maxillary canine impaction in orthodontics. While the literature is replete with studies that utilise the sector method, the alpha angle is an alternative approach to assess the possible eruptive outcome of the unerupted canine. It has been reported that if the alpha angle is greater than 25°, there is the possibility of external root resorption. However, if the alpha angle is more than 31°, the prospect of canine eruption decreases even if the deciduous canine is extracted as an interceptive measure. The dental pantomograph has historically been used to predict canine eruption or possible impaction. The use of this method, however, is wrought with limitations. These limitations include magnification, distortion and blurred images. The use of cone-beam computed tomography has been advocated as a means to overcome these limitations.

O objetivo deste estudo prospectivo foi avaliar tridimensionalmente a remodelação e o deslocamento do côndilo mandibular na fossa articular nos indivíduos, pós-surto de crescimento pubertário, tratados com aparelho Herbst bandado. A amostra foi constituída por 24 indivíduos, de ambos os gêneros, leucodermas, com idade cronológica média de 16 anos e 1 mês. Os indivíduos foram tratados com aparelho Herbst bandado por um período de 8 meses (média da amostra: 9,8 meses). Para a avaliação da remodelação do côndilo mandibular foram utilizadas tomografias computadorizadas de feixe cônico (TCFC) em dois tempos, denominados de T1 (antes da colocação do aparelho e T2 (após a remoção do mesmo). As tomografias foram obtidas pelo tomógrafo i-CAT Classic e os dados foram exportados no formato DICOM (Digital Image and Comunication in Medicine) e avaliados no programa Dolphin® Imaging 11.5 Premium. As medidas foram analisadas nas imagens dos cortes multiplanares (planos coronal, sagital e axial) por um observador, previamente calibrado. Os dados obtidos foram calculados pelo sistema de coordenadas cartesianas tridimensionais em um programa de software Matlab desenvolvido pelo Departamento de Física e Biofísica, da Faculdade Estadual Paulista – UNESP de Botucatu. Para avaliar o grau de concordância entre as mensurações empregouse o coeficiente de correlação intraclasse (ICC). À exceção das medidas FOE (eixo Z), C1E (no eixo X) e C2-T2 em ambos os lados, todas as demais medidas apresentaram alto grau de reprodutibilidade, denotando que o erro do método pode ser desprezado. O deslocamento dos côndilos, no sistema de coordenadas cartesianas, foi calculado com o Ponto Zero na Base do crânio; a remodelação foi calculada com o Ponto Zero na média da distância dos forames mentuais direito e esquerdo, forneceu uma análise quantitativa e qualitativa e distâncias euclidianas. Com relação a base do crânio, o côndilo direito se deslocou de forma moderada (0,71mm) para baixo e de forma relevante (0,91mm) para frente; o côndilo esquerdo se deslocou de forma relevante (0,93mm) para baixo e de forma moderada (0,73mm) para frente. O côndilo direito remodelou de forma relevante 1,08mm para trás e se distanciou da média da distância dos forames mentuais de forma relevante (1,19mm); o côndilo esquerdo remodelou de forma relevante 0,98mm para cima e se distanciou da média da distância dos forames mentuais de forma relevante (0,93mm). Foram mensurados os espaçamentos entre os pontos nos côndilos direito e esquerdo, em relação a fossa articular, sendo observado aumento de forma média, do espaçamento superior do côndilo esquerdo (0,34mm). O tratamento não promoveu alterações significantes nas medidas no eixo X, constatando que não houve movimento de lateralidade. Conclui-se que, com relação a base do crânio, os côndilos direito e esquerdo se deslocaram para baixo e para frente. O côndilo direito remodelou para trás enquanto que o côndilo esquerdo remodelou para cima.
The aim of this prospective study was to evaluate in 3-D the remodeling and displacement of the mandibular condyle in the glenoid fossa in the individuals, post-pubertal growth outbreak, treated with the banded Herbst appliance. The sample consisted of 24 individuals of both genders, leucoderma, with a mean chronological age of 16 years and 1 month. Subjects were treated with banded Herbst appliance during 8 months. Cone beam computed tomography (CBCT) was performed in two times to evaluate the condylar remodeling: T1 (prior to placement of the device) and T2 (after removal).) CT scans were obtained by i-CAT tomography Classic and the data were exported in DICOM (Digital Image and Communication in Medicine) format and evaluated in the Dolphin® Imaging 11.5 Premium program. The measurements were analyzed in multiplanar sections images (coronal, sagittal and axial planes) by an observer, previously calibrated. The data obtained were calculated by 3-D Cartesian coordinate system in a Matlab software, developed by the Department of Physics and Biophysics, UNESP Botucatu. To evaluate the agreement degree between the measurements, the intraclass correlation coefficient (ICC) was used. With the exception of the measurements FOE (Z axis), C1E (X axis) and C2-T2 on both sides, all other measurements showed a high degree of reproducibility, denoting that the error of the method can be neglected. The displacement of the condyles in the Cartesian coordinate system was calculated with the Zero Point in the skull base; the remodeling was calculated with the Point Zero in the mean distance of the right and left mental foramina, provided a quantitative and qualitative analysis and Euclidean distances. In relation to skull base, the right condyle moved moderately (0.71 mm) downwards and significantly (0.91 mm) forward; the left condyle shifted significantly (0.93mm) downwards and moderately (0.73mm) forward. The right condyle significantly remodeled 1.08mm behind and distanced itself from the mean distance of the mental foramina significantly (1.19mm); the left condyle significantly reshaped 0.98mm upward and distanced itself from the mean distance of the mental foramina significantly (0.93mm). The spacing between the points on the right and left condyles were measured, in relation to the glenoid fossa; there was a mean increase in the superior space of the left condyle (0.34 mm). The treatment did not promote significant changes in the measurements on the X axis, noting that there was no laterality movement. It was concluded that, with respect to the skull base, the right and left condyles moved downwards and forward. The right condyle remodeled backwards while the left condyle remodeled upward.

This study aimed to evaluate cephalometrically, by means of Cone Beam Computed Tomography (CBCT), the dentoalveolar and skeletal effects of Class II correction ith the Forsus® appliance. Study group was composed by 10 patients, 7 males and 3 females, with initial mean age of 16,1 years, with at least ½ Class II, minimum overjet of 5mm, no supernumeraries, anodontia or permanent teeth loss. Facial pattern should be meso or brachyfacial. Patients were evaluated and it was shown they were at stage IV or V of bone maturation, seen by cervical vertebrae. Forsus utilization period was 7,16 years on average, with a CBCT (T1) before and another one (T2) after the removal of Forsus. Paired t-test was used for statistical analysis. Results showed a decrease of SNA and a small grown of mandible, what improved maxillomandibular relationship; there was a counter-clockwise mandibular rotation and a clockwise rotation of the occlusal plane. Upper incisors were retruded, retroclined and extruded, and upper molars showed distal angulation. Lower incisors were proclined and intruded, and lower molars were mesialized and extruded. So, Forsus appliance showed to be effective in Class II correction, proportioning more dentoalveolar alterations than skeletal changes.
Este estudo teve como objetivo avaliar cefalometricamente as alterações dentoesqueléticas decorrentes do tratamento da maloclusão de Classe II, divisão 1, com o aparelho Forsus®, por meio de Tomografia Computadorizada de Feixe Cônico (TCFC). O grupo avaliado foi composto por 10 pacientes, sendo 7 do sexo masculino e 3 do sexo feminino, com idade média de 16,1 anos, maloclusão com severidade mínima de 1/2 Classe II, trespasse horizontal mínimo de 5 mm, padrão facial meso ou braquifacial. Estes jovens se encontravam no estágio IV ou V de maturação óssea, verificada pelas vértebras cervicais. O tempo de uso do aparelho Forsus foi de 7,16 meses (média), período de avaliação compreendido entre a aquisição da primeira teleradiografia gerada através da TCFC (T1 - pré-Forsus) e da segunda teleradiografia (T2 - pós-Forsus). Para análise estatística foi utilizado o teste-t pareado. Os resultados mostraram um pequeno crescimento mandibular que, juntamente com uma diminuição do SNA levaram a uma melhora da relação maxilomandibular. Houve uma rotação no sentido anti-horário da mandíbula e do plano oclusal no sentido horário. Os incisivos superiores foram retruídos, verticalizados e extruídos e os molares superiores distalizaram por inclinação. Houve vestibularização, protrusão e intrusão dos incisivos inferiores, além de mesialização e extrusão dos molares inferiores. Desta maneira, conclui-se que o aparelho Forsus foi efetivo na correção da maloclusão de Classe II, propiciando maiores alterações dentoalveolares do que esqueléticas.(AU)

Abstract:
AbstractConventional transcranial magnetic stimulation (TMS) coils are limited by the depth-focality tradeoff rule. To better utilize this depth-focality tradeoff rule, a new approach needs to be employed. In this study, a new multi-layer winding-tilted TMS coil design is proposed for human brain stimulation. It can deliver stimulation with better depth-focality characteristic than the double cone coils to deep brain regions. In our design, circular coils were accumulated along their central axis to improve the field decay rate as a function of the stimulation depth. We also tilted the winding angle of the coils to break the ring-shaped symmetry of the electric field distribution and accomplish the focality. New curves were plotted in the depth-focality tradeoff profile for our coil design, which intersected with the figure-8 coil curve. The new curves break the depth-focality tradeoff, and our coil design presents better focality than the H coils and circular coils, deeper stimulation depth than figure-8 coils, and the capability for multisite brain stimulation due to its unique structure and the limited contact area with the human head surface, which cannot be accomplished with the double cone coils.

Abstract:
Dissipative particle dynamics (DPD) is an emerging method for simulating problems at mesoscopic time and length scales. In this paper, we present a new algorithm to describe the hydrodynamics of a perfect conductive fluid in the presence of an electric field. The model is based on solving the electrostatic equations in each DPD time step for determining the charge distribution at the fluid interface and, therefore, corresponding electrical forces exerted by the electric field to the particles near the interface. The method is applied to a perfect conductive pendant drop which is immersed in a perfect dielectric and hydrodynamically inactive ambient. We have shown that when the applied voltage is sufficiently high, the drop shape is changed to a cone with an apex angle which is near to the Taylor analytical estimation of 98.6°. Our results reveal that the presented algorithm gives new capabilities to the conventional DPD method for simulating nanoscale problems in the presence of an electric field.

Abstract:
Conical structures arising on the surface of a liquid with surface conductivity in an electric field are considered taking into account the influence of space charge of particles emanating from the cone apex. It is demonstrated that the field distribution problem admits an exact self-similar solution corresponding to the Taylor scaling law. This solution allows us to determine the relation between the total electric current flowing through the cone and the cone and space-charge region half-angles. The structure of this relation is quite sophisticated; it changes essentially with changing the permittivity of a liquid and the mobility of carriers.

Abstract:
This paper reports experimental measurements of film thickness for continuous fluid flow within a spinning cone. The results are compared to analytical theory for thin film flow and found to be in good agreement. Spinning cones are used in various industrial process machines, including spinning cone distillation columns, centrifugal film evaporators and continuous centrifugal filters. In each case a fluid is fed continuously into the centre of a conical vessel which spins about a vertical axis with the cone apex pointing downwards. The fluid acquires the angular velocity of the cone and migrates up the internal wall of the cone under centrifugal force. Knowledge of the film thickness and flow velocity is often important in order to understand other performance parameters of the process such as evaporation or filtration rates. This paper aims to aid the design of new process machines by providing a mathematical model for film thickness that is validated by experimental results. Experiments have been conducted in which the angle of cone, angular velocity and input flow rate were all varied. Film thickness measurements were obtained via a novel optical method based on photographing the displacement of a projected grid on the surface of the flow within the cone. The method has the advantages of not disturbing the flow in any way and can provide thickness measurements over the whole cone depth. Measurements are also made insensitive to any transients by use of relatively long photographic exposures. Measurements are compared to analytical theory for axisymmetric, steady state, free-surface laminar flow of a Newtonian fluid in a spinning cone. The theory assumes the flow is thin but takes account of gravity. The theoretical model is found to be in good agreement with the experimental results.

Abstract:
Joining of the dissimilar metal pair NiTi to stainless steel is of great interest for implantable biomedical applications. Formation of brittle intermetallic phases requires that the joining processes limit the amount of over-melting and mixing along the interface. Thus, laser joining is a preferred method due to its ability to precisely control heat input. This study explores a method of using a cup and cone interfacial geometry, with no filler material, to increase the tensile strength of the joint. Not only does the cup and cone geometry increase the surface area of the interface, but it also introduces a shear component, which is shown to be beneficial to tensile strength of the wire as well. The fracture strength for various cone apex angles and laser powers is determined. Compositional profiles of the interfaces are analyzed. A numerical model is used for explanation of the processing.

Abstract:
We propose mathematical models for turbulent round atomized liquid jets that describe its dynamics in a simplebut comprehensive manner with the apex angle of the cone being the main disposable parameter. The basic assumptions are that (i) the jet is statistically stationary and that (ii) it can be approximated by a mixture of two fluids with the phases in local dynamic equilibrium, or so-called locally homogeneous flow (LHF). The models differ in their particular balance of explanatory capability and precision. To derive them we impose partial conservation of the initial mass and energy fluxes, introducing loss factors again as disposable parameters. Depending on each model, the equations admit explicit or implicit analytical solutions or a numerical solution in the discretized model case. The described variables are the the two-phase fluid’s composite density and velocity, both as functions of thedistance from the nozzle, from which the dynamic pressure is calculated.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4778

Full text
Abstract:
Straight bevel gears are usually manufactured with various machines and systems, and the tooth profiles are produced by grinding or machining by means of a tool with many cutting edges. In recent years, the straight bevel gear has been manufactured by an end mill using a CNC milling machine because the use of the auxiliary apparatus, special cutters, and special machine tools are not needed. Using this method, the gear manufacturing with high accuracy is important problem. In this paper, the coordinate measurement of the straight bevel gear manufactured in this method is performed and the gear accuracy is evaluated. The tooth profiles of a straight bevel gear generated by a quasicomplementary crown gear instead of a conventional complementary crown gear is introduced. For this study, first the tooth profiles of the straight bevel gear were modeled using a 3D-CAD system and the gear was manufactured by an end mill using a CNC milling machine based on a CAM process. Afterward, the coordinates of many points on the gear tooth surfaces were measured at random using a coordinate measuring machine. This coordinate measurement provides the information about the factors relation to the gear accuracy such as pressure angle, tooth angle error, root cone angle, and apex to back and so on. Therefore, the values of the above factors were estimated and were compared with the theoretical ones, respectively.

Abstract:
The launching efficiency (η) from semiconductor lasers into plane-ended (PE) multimode fibers is low(~10 20%). We polished PE into rooftop (RT) ends, having a RT angle of 65° to the fiber axis, and observed a substantial increase in η; 27% (PE) to 51 % (RT). This was achieved (ηmax) after optimizing the apex position of RT fiber with respect to the stripe; the two have to be parallel. When they were perpendicular, ηmin = 29% was obtained. The effect of longitudinal, lateral, and angular misalignments was compared for the PE and RT ends; the latter were always more critical. We further investigated, for the first time, the effect on the intermodal pulse dispersion and obtained the following results: (i) output FWHM after 1 m having PE or RT end was 0.57 ns, (ii) FWHM after 1 km with PE input was 0.70 ns, giving pulse dispersion (t m ) of 0.41 ns, (iii) FWHM after 1 km with RT input and r/max was 0.61 ns giving t m = 0.22 ns, (iv) FWHM after 1 km with RT end and ηmin was 0.65 ns giving t m = 0.31 ns. The material dispersion was negligible. Hence comparing (ii) and (iii) above, t m was reduced by a factor of 2. This was explained by alteration of the modal power distribution in fiber core and confirmed by output far-field measurements.
