  The study conducts an experimental investigation to compare the effect of accelerated aging on a glass fiber/vinylester matrix filament wound composite. Two static aging conditions, thermal and hygrothermal, were chosen. Samples were aged at temperatures below the glass transition temperature (Tg) of vinylester for 224 days. Mechanical test – ILSS and flexure testing and physicochemical assessments – DMA, FTIR and colorimetry were conducted to gauge the aging effects on long-term durability and appearance. Results are presented as retained property values over aging durations and environments. Notably, coupons aged below 60 °C under both conditions exhibited residual curing, enhancing mechanical properties. Time-temperature coupling influenced behavior, with higher temperatures and longer durations leading to degradation. Hygrothermal aging at 80 °C prompted earlier degradation than thermal aging, highlighting moisture's impact. DMA revealed interfacial degradation for hygrothermally aged coupons, verified by fractography. Conversely, damping factor analysis indicated residual curing for thermally aged coupons. Results were confirmed through color change and FTIR, showcasing evolving chemical patterns with aging.

  Additively manufactured (AM) parts still lack a thorough understanding of their optical properties, particularly surface texture and reflectance characteristics at different viewing angles. This study examines the reflectance properties of material jetting (MJT) parts using bidirectional reflectance distribution functions (BRDFs). The visual appearance of the MJT parts was analyzed using a gonio-spectrophotometer at 328 unique incidence and viewing geometries for seven different wedge angles for build orientation (BO) from 0° to 90° at 15° intervals. The redundancy analysis (RDA) and principal component analysis (PCA) were used to study BO and to determine the prominent measurement geometries. The results indicate higher BOs resulted in more color and texture variation and rougher surfaces, with Sq 4.21 μm vertical compared to 1.42 μm for horizontal BOs. Furthermore, it affected the visual representation and parametric estimation of BRDF, where significantly lower luminance, more diffuse reflection, and less hue distribution were observed for all CMYK resins printed at higher BOs. Accordingly, vertically printed surfaces showed a wider near-to-specular luminance area than other BOs. An analysis of the bidirectional reflectance property suggests that a gonio-spectrophotometer can be embedded in the printing process and quality assurance in AM as a computationally efficient model.

  Material jetting (MJT) is a promising additive manufacturing (AM) technique that offers high-quality appearance reproduction. Considering the limited selection of aesthetic materials available for MJT technology, a thorough optical analysis is required to determine their optimal application. This study focuses on the prominent appearance attributes in MJT and the role of texture variation due to different build orientations (BOs). For this purpose, tilted surfaces were manufactured in a direction ranging from 0° to 90° degrees at 15° intervals. The spectral reflectance, absorbance, transmittance, color difference, gloss, haze, scattering, and texture of MJT objects with varying BOs were investigated. To illustrate the variation in visual appearance and texture of the studied surfaces, the optical properties were rendered to three-dimensional (3D) spherical models. Further, the interaction of the appearance of 3D printing interacts with the quality improvement of AM surfaces is discussed. The results indicated that BO significantly affected the surface texture and layer orientation, leading to variation in surface quality by impacting all studied appearance attributes. Furthermore, tilted MJT surfaces exhibited more variation in reflectance than transmittance. As a result of the Kendall rank correlation coefficient and principal component analysis (PCA), light transmittance through parts manufactured at BO 75° showed the largest variation compared to 0°. Regarding light reflectance, 60° showed more variation among studied angles. The results of gloss, haze, and scattering studies revealed the significance of the measurement direction due to the role of microsurface normals in the surface texture.

  As a result of the associated costs and environmental impacts, Material Jetting (MJT) plays a limited role in Additive Manufacturing (AM). Research on the durability and long-term performance of MJT objects by evaluating their appearance is lacking. The objective of this study is to investigate the effect of aging on the color and the physico-mechanical performance of MJT parts. This work examines the influence of production settings on objects subjected to a total of 103days of accelerated aging. The studied Printing Primary Parameters (PPPs) were resin color, build platform position (swath), and finishing configurations. The results indicated the response of the studied PPP according to the aging time was non-linear due to the dynamic appearance response to aging time. VeroBlackPlus and VeroCyan photo resins demonstrated superior color fidelity through aging by a color difference of less than 10. Based on Taguchi and Redundancy Analysis (RDA), mechanical and physicochemical properties varied the most after 58 days of accelerated aging, with elastic modulus retention up to 149.21% and Glass Transition temperature (Tg) up to 116.6%. This study demonstrates the importance of considering long-term performance during the design process of AM products, depending on the intended application and service conditions.

  Material jetting (MJT) products have a high subjective appearance quality in additive manufacturing (AM). MJT objects are typically manufactured from multiple layers of semi-transparent photo resins to achieve the desired appearance. This study explores the optical properties of photopolymer plates in monolayer and bilayer combinations. The role of the white substrate as the background plate in bilayer configurations is discussed concerning appearance reproduction in MJT parts. For this purpose, spectral reflectance, transmittance, absorbance, color difference, and texture were investigated for MJT objects with different plate combinations. The primary digital materials in MJT were further investigated for haze, gloss, scattering variations, and their corresponding bidirectional reflectance distribution functions (BRDFs). The optical properties of the studied surfaces were then applied to three-dimensional (3D) models to illustrate the variation in visual appearance and texture. According to the results, it was inevitable to use a white background plate for color reproduction. Therefore, increasing the layer thickness did not improve color fidelity. Due to the role of microfacet normals in the surface texture, gloss, haze, and scattering, results followed the same analysis pattern but depended on the measurement direction.

  Surface roughness is gaining increasing recognition in the processing design methods of additive manufacturing (AM) due to its role in many critical applications. This impact extends not only to various AM product manufacturing but also to indirect applications, such as molding and casting. This review article discusses the role of processing on the surface roughness of AM-printed polymers with limited post-processing by summarizing recent advances. This review offers a benchmark for surface quality improvement of AM processes, considering the surface roughness of polymeric parts. For this purpose, it lists and analyzes the key processes and various printing parameters used to monitor and adjust surface roughness under given constraints. Four AM techniques for manufacturing polymeric parts are compared: fused filament fabrication (FFF), selective laser sintering (SLS), vat photopolymerization (VPP), and material jetting (MJT). A review and discussion of recent studies are presented, along with the most critical process parameters that affect surface roughness for the selected AM techniques. To assist in selecting the most appropriate method of 3D printing, comparable research summaries are presented. The outcome is a detailed survey of current techniques, process parameters, roughness ranges, and their applicability in achieving surface quality improvement in as-printed polymers.

  Filament winding is a technique to manufacture tubular composite structures and, therefore, is among the most appealing techniques for fabricating critical structures such as hollow tubes. Despite the recent advances, these structures are prone to a varying degree of porosity that may affect their mechanical performance. Therefore, the accurate detection and quantification of the manufacturing porosity is crucial. Micro-CT is most suitable for performing this activity at various scales. This work employs micro-CT for studying porosity inside an as-manufactured filament-winded composite structure. Void characteristics like volume, orientation, size, and relative volume fraction inside the hoop and helical layers are quantified inside a representative curved panel extracted from a glass fiber-vinyl ester tubular composite structure, which has not been studied in detail previously. It was observed that most voids are present in the matrix region. The voids are elliptical rod-like and spherical, with the latter present in the helical layers, which also host the majority of voids and the highest void volume fractions. The voids are highly aligned along the fiber orientation direction with higher misorientations for helical layers than the hoop layer. Large voids in base layers were created due to gaps formed during the winding process. Hence, the main goal of this study is to measure the voids' characteristics and the volumetric fraction during the stacking of filament wound hoop and helical layers during a generic filament winding pattern. The data can be further exploited as input for modeling filament winded composites in the presence of voids by researchers.

  This study examines the impact of additive manufacturing (AM) settings on the durability of 3D-printed polymer composite objects in terms of object color appearance and corresponding mechanical properties when subjected to simulated environmental conditions using accelerated aging. For this purpose, the AM pre-processing factors that influence the performance of the composite material, such as build platform position, color, and finishing configurations, are discussed. The experimental campaign was designed according to the Taguchi method to minimize the color difference and maximize the mechanical parameters. The results indicate that the best factor parameters for each performance characteristic differ following the design goal. Accordingly, black-on-white with a glossy-on-matte finish manufactured on the outer swath demonstrated the best color and mechanical performance fidelity, where the studied properties were not altered significantly due to aging.

  Predicting the long-term response of polymer composite materials is a continuous challenge to the composite industry. The service aging of structural composites has different effects on composites’ physicochemical behavior manifested as changes in the mechanical properties. This work presents the effects of hot/wet and hot/dry accelerated aging conditions on the interlaminar shear properties of vinyl-ester glass fiber coupons made with filament winding. The test coupons were aged for 224 days, removed and tested after every 28, 56, 112, and 224 days. It was observed that the response of composite coupons is different for the hot/wet and hot/dry aging environments for same duration of aging. This is attributed to the time-temperature-environment coupling during the aging regime. The overall response of the composite behavior is then represented via retention curves and degradation maps that can help correlate the results for both hot/wet and hot/dry aging environment as a function of exposure times and temperatures. The findings of the study thus provide an insight on the dependence of matrix-dominated properties of composite. The results can be taken into account when designing structure made from vinyl-ester glass fiber filament winded composite which foresee aging in hot/wet and hot/dry conditions.

  Material jetting (MJT) is a recognized additive manufacturing (AM) method to combine various materials and create a wide range of designed appearances. However, the measured color of MJT objects is frequently different from the color provided in the printer software. As a result, estimating the color quality and the measured color attributes of an object before printing is vital for accurate color reproduction. This study investigates the color variation based on the texture in an object 3D-printed using the MJT method on a rotary tray. The novel radial shape of the rotary tray build platform and variation in the layers structure were targeted as the main factors that can increase the uncertainty in accurate color reproduction. The influence of the PolyJet printer setup has been examined by thickness variation of the colored layers, location on the tray (swath selection), ink color, and finish type between layers. Color quality was assessed by comparing the produced object color by calculating spectral and colorimetric differences. Spearman rank correlation coefficient and principal component analysis (PCA) methods were used to analyze the direct or indirect influence of independent categorical factors on the measured color variables. Based on the studied parameters, switching swathes did not fail printer objects for industrial color matching. In contrast, a thickness variation as small as 0.5 mm could cause CIEDE2000 above 5 for most models, resulting in unnatural color reproduction. Color differences in most objects might be discernible to inexperienced observers, depending on the 3D printing parameters.

  The structural and mechanical properties of Fe-Al compounds (FeAl, FeAl, FeAl, FeAl, FeAl, FeAl) have been studied using modified embedded atom method (MEAM) potentials. The equilibrium lattice constants, formation enthalpies, and elastic properties have been investigated and compared with other studies. The calculated lattice constants show good agreement with the embedded atom method (EAM) and density functional theory (DFT) calculations and with experiments. All Fe-Al compounds are mechanically stable according to the elastic constants restrictions. The calculated bulk modulus of the compounds does not show a linear relation with Fe concentration, which is most probably caused by the mechanical anisotropy of Fe-Al compounds. However, comparison of the Fe-Al mechanical properties of MEAM, DFT and EAM-based approaches and experiments show non-consistent differences, which reflects uncertainties with several of these methods, due to assumptions and simplifications imposed during calculations. In general, DFT calculations are closer to experimental observations than semi-empirical potentials. Comprehensive comparisons are made based on theoretical and experimental methodologies.

  The surface appearance in additive manufacturing (AM) has attracted attention in recent years due to its importance in evaluating the quality of 3D printed structures. Fused Deposition Modeling (FDM), also known as Fused Filament Fabrication (FFF), holds an important share of the AM market because of its large economic potential in many industries. Nevertheless, the quality assurance procedure for FDM manufactured parts is usually complicated and expensive. The enhancement of the appearance at different illumination and viewing angles can be exploited in various applications, such as civil engineering, aeronautics, medical fields, and art. There are two steps in improving the microstructure and material appearance of printed objects, including pre-processing and post-processing. This study aims to elucidate the role of the pre-processing phase in the development of FDM parts through the assessment of color differences. For this purpose, a set of polymeric samples with different wedge (slope) angles were 3D printed using an FDM printer. The color difference between the elements is discussed and correlated with the pre-processing parameters. It is revealed that the wedge angle of the elements in the design, slicing process, and infill density could alter the color appearance of the printed parts in a predictable trend. This research suggests that low infill density and wedge angles in polylactide filaments can result in a more stable color appearance.

  The interfacial strengths of a low misfit Fe2Al5//Fe interface structure found at aluminum-steel joints has been studied using density functional theory. An interface between Fe and Fe2Al5 was selected based on a criteria of low lattice misfit and number of atoms. Through virtual tensile testing of bulk Fe2Al5 and the interface structures we show that the energy-displacement curve can be well described by including extra polynomial terms in the Universal Binding Energy Relation (UBER). It is shown that the Fe2Al5//Fe interface has a higher tensile strength than the bulk Fe2Al5 phase. We also find that the shear deformation process potentially can be initiated from an Fe-terminated interface.

  First-principles virtual tensile and shear strength calculations have been performed on the Fe2Al5// Fe4Al13 and -AlFeSi// Fe4Al13 interfaces. The Fast Inertial Relaxation Engine (FIRE) algorithm is used for optimizing these complex Intermetallic Compound (IMC) interface structures. To characterize the virtual tensile strength, an extended generalized Universal Binding Energy Relation (UBER) was used to fit the energy-displacement data. The virtual tensile strength was evaluated with the Rigid Grain Shift (RGS) methodology without atomic relaxations during tensile displacement and with RGS+relaxation with atomic relaxations. All calculated values for IMC//IMC interfaces in this study are compared with pure Al//Fe and Al//IMCs [1] interfaces to identify the role of IMCs at aluminum-steel joints.

  First-principles virtual tensile and shear test calculations have been performed to Al(0 0 )//-AlFeSi(0 0 1) and Al(0 4)//Fe4Al13(1 0 ) interfaces by the ab initio pseudo potential density functional theory method. Work of separation, ultimate tensile strength and shear strength of bulk and interface structures were calculated. The Al(0 0 )/-AlFeSi(0 0 1) interface showed higher tensile strength than the Al(0 4)//Fe4Al13(1 0 ) interface structure. Moreover, interface calculations revealed a charge depletion region in the second layer of the Fe4Al13 structure, which caused lower work of separation. Furthermore, shear calculations showed stronger shear strength for the Al(0 4)//Fe4Al13(1 0 ) interface than for the Al(0 0 1)//-AlFeSi(0 0 1) interface structure.

  The topic of the chapter is track and vertex reconstruction in particle detectors. The reconstruction of (charged) tracks and the subsequent reconstruction of interaction vertices are important steps in the data analysis chain of an experiment in high-energy physics. Track reconstruction typically proceeds in three steps: Track Finding; Track Fitting; and Testing the track hypothesis. The most important pattern recognition algorithms and statistical estimation methods applied in this context are presented in the first section of the chapter, along with material on track-based alignment and formulas for the quick assessment of the momentum resolution of a tracking system. The following section deals with the reconstruction of interaction vertices, including both the primary interaction vertex in the collision zone of an experiment and secondary decay vertices of unstable particles. The pattern recognition methods and statical estimators involved are in many respects similar to the ones deployed in track reconstruction. The final section presents a brief overview of track and vertex reconstruction in the four LHC experiments. The methods applied by the experiments are described and their performance is illustrated by results from a few selected physics channels.

  A measurement of the mass of the W boson is presented based on proton–proton collision data recorded in 2011 at a centre-of-mass energy of 7 TeV with the ATLAS detector at the LHC, and corresponding to 4.6 fb−1 of integrated luminosity. The selected data sample consists of 7.8×106 candidates in the 𝑊→𝜇𝜈 channel and 5.9×106 candidates in the 𝑊→𝑒𝜈 channel. The W-boson mass is obtained from template fits to the reconstructed distributions of the charged lepton transverse momentum and of the W boson transverse mass in the electron and muon decay channels, yielding 𝑚𝑊=80370=80370±7 (stat.)±11(exp. syst.)±14 (mod. syst.) MeV±19MeV, where the first uncertainty is statistical, the second corresponds to the experimental systematic uncertainty, and the third to the physics-modelling systematic uncertainty. A measurement of the mass difference between the 𝑊+ and 𝑊− bosons yields 𝑚𝑊+−𝑚𝑊−=−29±28 MeV.

  The modification of the production of 𝐽/𝜓 , 𝜓(2S) , and 𝛶(𝑛S) ( 𝑛=1,2,3 ) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of 28 nb−1 and 25 pb−1 respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of 𝐽/𝜓 and 𝜓(2S) are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, 𝑅𝑝Pb for 𝐽/𝜓 and 𝛶(𝑛S) . No significant modification of the 𝐽/𝜓 production is observed while 𝛶(𝑛S) production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions.

  Two phase Stefan problem was solved using analytical method in cylindrical domain. To solve governing equations Eigen conditions were formulated by using separation of variable technique. Eigenvalues of the eigencondition were obtained by applying corresponding boundary conditions for liquid and solid phase. Eigenvalues are graphically validated by using window size method in Mathematica. It is noted radial eigenvalues are free from imaginary values. Interface equation obtained from this method were solved and analyzed by varying the Stefan number and introducing the forced and natural convection. Conduction and convection heat transfer mechanism was studied and results obtained by varying thermal diffusivity, thermal conductivity and Stefan number were discussed. Natural convection effects were studied by introducing Rayleigh number and results showed Stefan number has significant effect than Rayleigh number during Phase transition process. Furthermore, eigen function expansion Method was compared with exact solution of Exponential Integral function method and results showed good agreement for Q = 1.

  A measurement of the fragmentation functions of jets into charged particles in collisions and pp collisions is presented. The analysis utilizes 28 nb−1 of data and 26 pb−1 of pp data, both at = 5.02 TeV, collected in 2013 and 2015, respectively, with the ATLAS detector at the LHC. The measurement is reported in the centre-of-mass frame of the nucleon–nucleon system for jets in the rapidity range ⁎ 1.6 and with transverse momentum 45 260 GeV. Results are presented both as a function of the charged-particle transverse momentum and as a function of the longitudinal momentum fraction of the particle with respect to the jet. The pp fragmentation functions are compared with results from Monte Carlo event generators and two theoretical models. The ratios of the to pp fragmentation functions are found to be consistent with unity.

  Finding and fitting circles from a set of points is a frequent problem in the data analysis of high-energy physics experiments. In a tracker immersed in a homogeneous magnetic field, tracks are close to perfect circles if projected to the bending plane. In a ring-imaging Cherenkov (RICH) detector, circles of photons around the crossing point of charged particles have to be found and their radii estimated. In both cases, non-negligible background may be present that tends to complicate the pattern recognition and to bias the circle fit. In this contribution we present a robust circle fit based on a modified Riemann fit that removes or significantly reduces the effect of background points. As in the standard Riemann fit, the measured points are projected to the Riemann sphere or paraboloid, and a plane is fitted to the projected points. The fit is made robust by replacing the usual least-squares regression by a least median of squares (LMS) regression. Because of the high breakdown point of the LMS estimator, the fit is insensitive to background points. The LMS plane is used to initialize the weights of an M-estimator that refits the plane in order to suppress eventual remaining outliers and to obtain the final circle parameters. The method is demonstrated on three sets of artificial data: points on a circle plus a comparable number of background points; points on two overlapping circles with additional background; and points obtained by the simulation of tracks in a drift chamber with mirror points and additional background. The results show high circle finding efficiency and small contamination of the final fitted circles.

  Two-particle pseudorapidity correlations are measured in \(\sqrt{s_{\rm{NN}}}\) = 2.76 TeV Pb+Pb, \(\sqrt{s_{\rm{NN}}}\) = 5.02 TeV \(p\)+Pb, and \(\sqrt{s}\) = 13 TeV \(pp\) collisions at the LHC, with total integrated luminosities of approximately 7 \(\mu\mathrm{b}^{-1}\), 28 \(\mathrm{nb}^{-1}\), and 65 \(\mathrm{nb}^{-1}\), respectively. The correlation function \(C_{\rm N}(\eta_1,\eta_2)\) is measured as a function of event multiplicity using charged particles in the pseudorapidity range \(|\eta|<2.4\), The correlation function contains a significant short-range component, which is estimated and subtracted. After removal of the short-range component, the shape of the correlation function is described approximately by \(1+\langle{a_1^2}\rangle \eta_1\eta_2\) in all collision systems over the full multiplicity range. The values of \(\sqrt{\langle{a_1^2}\rangle}\) are consistent between the opposite-charge pairs and same-charge pairs, and for the three collision systems at similar multiplicity. The values of \(\sqrt{\langle{a_1^2}\rangle}\) and the magnitude of the short-range component both follow a power-law dependence on the event multiplicity. The \(\eta\) distribution of the short-range component, after symmetrizing the proton and lead directions in \(p\)+Pb collisions, is found to be smaller than that in \(pp\) collisions with comparable multiplicity.

  This paper presents the method and performance of primary vertex reconstruction in proton--proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during 2012 at a centre-of-mass energy of \(\sqrt{s} = 8\) TeV. The performance has been measured as a function of the number of interactions per bunch crossing over a wide range, from one to seventy. The measurement of the position and size of the luminous region and its use as a constraint to improve the primary vertex resolution are discussed. A longitudinal vertex position resolution of about \(30 \mu{\rm m}\) is achieved for events with high multiplicity of reconstructed tracks. The transverse position resolution is better than \(20 \mu{\rm m}\) and is dominated by the precision on the size of the luminous region. An analytical model is proposed to describe the primary vertex reconstruction efficiency as a function of the number of interactions per bunch crossing and of the longitudinal size of the luminous region. Agreement between the data and the predictions of this model is better than 3% up to seventy interactions per bunch crossing.

  A measurement of the calorimeter response to isolated charged hadrons in the ATLAS detector at the LHC is presented. This measurement is performed with 3.2 nb\(^{-1}\) of proton--proton collision data at \(\sqrt{s}=7\) TeV from 2010 and 0.1 nb\(^{-1}\) of data at \(\sqrt{s}=8\) TeV from 2012. A number of aspects of the calorimeter response to isolated hadrons are explored. After accounting for energy deposited by neutral particles, there is a 5% discrepancy in the modelling, using Geant4 physics lists, of the calorimeter response to isolated charged hadrons in the central calorimeter region. The description of the response to anti-protons at low momenta is found to be improved with respect to previous analyses. The electromagnetic and hadronic calorimeters are also examined separately, and the detector simulation is found to describe the response in the hadronic calorimeter well. The jet energy scale uncertainty and correlations in scale between jets of different momenta are derived based on these studies. The uncertainty is 2-5% for jets with transverse momenta above 2 TeV, where this method provides the jet energy scale uncertainty for ATLAS.

  Direct searches for lepton flavour violation in decays of the Higgs and \(Z\) bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: \(H\to e\tau\), \(H\to\mu\tau\), and \(Z\to\mu\tau\), The searches are based on the data sample of proton--proton collisions collected by the ATLAS detector corresponding to an integrated luminosity of 20.3 fb\(^{-1}\) at a centre-of-mass energy of \(\sqrt{s} = 8\) TeV. No significant excess is observed, and upper limits on the lepton-flavour-violating branching ratios are set at the 95% confidence level: Br\((H\to e\tau) <\) 1.04%, Br\((H\to\mu\tau) <\) 1.43%, and Br\((Z\to\mu\tau) <\) 1.69 \(\times\) 10\)^{-5}\),

  Recently, a new Riemann track fit which operates on translated and scaled measurements has been proposed. This study shows that the new Riemann fit is virtually as precise as popular approaches such as the Kalman filter or an iterative non-linear track fitting procedure, and significantly more precise than other, non-iterative circular track fitting approaches over a large range of measurement uncertainties. The fit is then extended in two directions: first, the measurements are allowed to lie on plane sensors of arbitrary orientation; second, the full error propagation from the measurements to the estimated circle parameters is computed. The covariance matrix of the estimated track parameters can therefore be computed without recourse to asymptotic properties, and is consequently valid for any number of observation. It does, however, assume normally distributed measurement errors. The calculations are validated on a simulated track sample and show excellent agreement with the theoretical expectations.

  Measurements of the electroweak production of a \(W\) boson in association with two jets at high dijet invariant mass are performed using \(\sqrt{s} = 7\) and \(8\) TeV proton--proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb\(^{-1}\) of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a \(W\) boson via a triple-gauge-boson vertex and include both the fiducial and differential cross sections of the electroweak process.

  The tracking performance parameters of the ATLAS Transition Radiation Tracker (TRT) as part of the ATLAS inner detector are described in this paper for different data-taking conditions in proton-proton, proton-lead and lead-lead collisions at the Large Hadron Collider (LHC). The performance is studied using data collected during the first period of LHC operation (Run 1) and is compared with Monte Carlo simulations. The performance of the TRT, operating with two different gas mixtures (xenon-based and argon-based) and its dependence on the TRT occupancy is presented. These studies show that the tracking performance of the TRT is similar for the two gas mixtures and that a significant contribution to the particle momentum resolution is made by the TRT up to high particle densities.

  During 2015 the ATLAS experiment recorded \(3.8 \mathrm{fb}^{-1}\) of proton--proton collision data at a centre-of-mass energy of \(13 \mathrm{TeV}\), The ATLAS trigger system is a crucial component of the experiment, responsible for selecting events of interest at a recording rate of approximately 1 kHz from up to 40 MHz of collisions. This paper presents a short overview of the changes to the trigger and data acquisition systems during the first long shutdown of the LHC and shows the performance of the trigger system and its components based on the 2015 proton--proton collision data.

  This open access book is a comprehensive review of the methods and algorithms that are used in the reconstruction of events recorded by past, running and planned experiments at particle accelerators such as the LHC, SuperKEKB and FAIR. The main topics are pattern recognition for track and vertex finding, solving the equations of motion by analytical or numerical methods, treatment of material effects such as multiple Coulomb scattering and energy loss, and the estimation of track and vertex parameters by statistical algorithms. The material covers both established methods and recent developments in these fields and illustrates them by outlining exemplary solutions developed by selected experiments. The clear presentation enables readers to easily implement the material in a high-level programming language. It also highlights software solutions that are in the public domain whenever possible. It is a valuable resource for PhD students and researchers working on online or offline reconstruction for their experiments.

  Studying surface texture and morphology is essential to developing Additive Manufacturing (AM). Assessing the quality of part layer compounds in the process will assist with adjusting process parameters for optimal part quality in the manufacturing process. For this purpose, Material Jetting (MJT) system has been used to manufacture objects at various platform locations (swathes) to examine the surface morphology, including surface roughness and texture. Due to the rotating disc used as the build platform, the studied parts showed a different surface morphology from parts printed using other material jetting machines. To study the surface texture, we generated high-resolution surface mesh grids after scanning the surface using a coordinate measuring machine (CMM) and a 3D scanner. The surface topography was decomposed into scan lines using a fast Fourier transform (FFT). The power spectral density (PSD) of a surface was calculated and compared to roughness to discuss the surface topography. Signal processing demonstrated that different textures can be fabricated by tuning the printing position conditions. As a result of determining the surface texture and roughness characteristics in conjunction with 3D printing parameters in the design process, it was possible to categorize the build platform regions based on their surface textures.
