description: We derive a kinematic variable that is sensitive to the mass of the Standard Model Higgs boson (M_H) in the H->WW*->l l nu nu-bar channel using symbolic regression method. Explicit mass reconstruction is not possible in this channel due to the presence of two neutrinos which escape detection. Mass determination problem is that of finding a mass-sensitive function that depends on the measured observables. We use symbolic regression, which is an analytical approach to the problem of non-linear regression, to derive an analytic formula sensitive to M_H from the two lepton momenta and the missing transverse momentum. Using the newly-derived mass-sensitive variable, we expect Higgs mass resolutions between 1 to 4 GeV for M_H between 130 and 190 GeV at the LHC with 10 fb^-1 of data. This is the first time symbolic regression method has been applied to a particle physics problem.

Gamification elements in smoking cessation mobile apps and their effects on the self-efficacy and motivation to quit of smokers
Creators: name: Weth, Nikita
Publisher: name: Imperial College London
Year: 2021

description: Background and Aim: Gamification can positively impact self-efficacy and motivation to quit, two vital factors associated with smoking cessation. Since it shares key components with behaviour change theories and is easily applicable to digital interventions, gamification has the potential of improving the effectiveness of mHealth solutions. However, the role of gamification in the context of smoking cessation and mHealth has been sparsely investigated. My research aims to examine gamification elements in smoking cessation mobile apps and quantitatively investigate their effects on the self-efficacy and motivation to quit of smokers seeking to quit. Methods: A review of smoking cessation apps on the UK market assessed app adherence to treatment guidelines and incorporation of gamification. One of two mobile apps identified from the review were assigned to smokers seeking to quit for a 4-week long study. Linear and logistic regression models investigated the effects of gamification on self-efficacy, motivation to quit and smoking cessation. Pairwise Pearson correlations compared self-reported and in-app engagement data. Statistical significance for all models and tests was determined at the 5% (.05) level. Results: Smoking cessation apps had low adherence to treatment guidelines and did not incorporate a high level of gamification. Compared to baseline, self-efficacy and motivation to quit statistically significantly increased after app use. Perceived engagement with overall gamification was associated with change in self-efficacy (β=3.35, 95% CI: 0.31 to 6.40) and motivation to quit (β=0.54, 95% CI: 0.15 to 0.94). Engagement with the steps/levels feature (based on self-reported and in-app data) was associated with change in self-efficacy and 7-day smoking cessation. Self-reported and in-app engagement data were positively moderately correlated. Conclusion: Gamification in mobile apps can have positive effects on the self-efficacy and motivation to quit of smokers. The findings provide important insights for tobacco control policymakers, mobile app developers and smokers trying to quit.
The roles of MUSE1 and MUSE15 in plant innate immunity
Creators: name: Dong, Xiaoou
Publisher: name: University of British Columbia

description: Nucleotide-binding leucine-rich repeat (NLR) immune receptors play crucial roles in pathogen recognition and defense activation in animals and plants. The immune responses mediated by NLR proteins are tightly regulated in plants so that the host effectively responds to pathogen attack without experiencing autoimmunity. However, the mechanisms underlying this regulation are not fully understood. To better understand this process, a mutant snc1-enhancing (MUSE) forward genetic screen was performed in model plant Arabidopsis thaliana. This thesis describes the identification and characterization of two genes encoding negative regulators of defense responses, MUSE1 and MUSE15, respectively. MUSE1 encodes a previously uncharacterized RING domain protein exhibiting E3 ubiquitin ligase activity. It has a close paralog in the Arabidopsis genome, which is MUSE2. Albeit both muse1 and muse2 single mutants are wild type (WT)-like, the muse1 muse2 double knockout mutant displays severe autoimmunity, suggesting their overlapping functions in regulating defense. Through epistatic analysis, it was found that the autoimmunity of muse1 muse2 is fully dependent on SNC1, suggesting that MUSE1 and MUSE2 are specifically involved in the regulation of SNC1-mediated immunity. Genetic and biochemical analyses excluded SNC1, bHLH84 and MOS10 from being potential ubiquitination substrates of MUSE1 and MUSE2, and offered clues to the identity of the substrates of MUSE1 and MUSE2. These findings add to the growing list of characterized E3 ubiquitin ligases involved in the stringent regulation of NLR-mediated immunity. MUSE15 encodes ADR1-L1, which belongs to the ADR1 helper NLR family. Previous studies have demonstrated that the ADR1 family is required for defense mediated by multiple sensor NLRs. Unexpectedly, loss of ADR1-L1 enhances immunity-related phenotypes in multiple autoimmune mutants including snc1, cpr1, bal and lsd1. This immunity-enhancing effect is not mediated by increased SNC1 protein stability, nor is it fully dependent on the accumulation of defense hormone salicylic acid (SA). Transcriptional analysis revealed an up-regulation of ADR1 and ADR1-L2 in the adr1-L1 background, which may over-compensate the loss of ADR1-L1, leading to stronger defense responses. The complex regulation within the ADR1 family extends our knowledge on the interplay among helper NLRs.

description: We use the Mars Regional Atmospheric Modeling System (MRAMS) to simulate lake storms on Mars, finding that intense localized precipitation will occur for lake size >=10^3 km^2. Mars has a low-density atmosphere, so deep convection can be triggered by small amounts of latent heat release. In our reference simulation, the buoyant plume lifts vapor above condensation level, forming a 20km-high optically-thick cloud. Ice grains grow to 200 microns radius and fall near (or in) the lake at mean rates up to 1.5 mm/hr water equivalent (maximum rates up to 6 mm/hr water equivalent). Because atmospheric temperatures outside the surface layer are always well below 273K, supersaturation and condensation begin at low altitudes above lakes on Mars. In contrast to Earth lake-effect storms, lake storms on Mars involve continuous precipitation, and their vertical velocities and plume heights exceed those of tropical thunderstorms on Earth. Convection does not reach above the planetary boundary layer for lakes <<10^3 km^2 or for atmospheric pressure >O(10^2) mbar. Instead, vapor is advected downwind with little cloud formation. Precipitation occurs as snow, and the daytime radiative forcing at the land surface due to plume vapor and storm clouds is too small to melt snow directly (

description: The pulsation periods of long period variables (LPVs) depend on their mass and helium abundance as well as on their luminosity and metal abundance. Comparison of the observed periods of LPVs in globular clusters with models is capable of revealing the amount of mass lost on the giant branch and the helium abundance.} {We aim to determine the amount of mass loss that has occurred on the giant branches of the low metallicity globular clusters NGC 362 and NGC 2808. We also aim to see if the LPVs in NGC 2808 can tell us about helium abundance variations in this cluster.} We have used optical monitoring of NGC 362 and NGC 2808 to determine periods for the LPVs in these clusters. We have made linear pulsation models for the pulsating stars in these clusters taking into account variations in mass and helium abundance. Reliable periods have been determined for 11 LPVs in NGC 362 and 15 LPVs in NGC 2808. Comparison of the observed variables with models in the logP - K diagram shows that mass loss of ~0.15-0.2 Msun is required on the first giant branch in these clusters, in agreement with estimates from other methods. In NGC 2808, there is evidence that a high helium abundance of Y~0.4 is required to explain the periods of several of the LPVs. It would be interesting to determine periods for LPVs in other Galactic globular clusters where a helium abundance variation is suspected to see if the completely independent test for a high helium abundance provided by the LPVs can confirm the high helium abundance estimates.

description: Auctions are becoming an increasingly popular method for transacting business, especially over the Internet. This article presents a general approach to building autonomous bidding agents to bid in multiple simultaneous auctions for interacting goods. A core component of our approach learns a model of the empirical price dynamics based on past data and uses the model to analytically calculate, to the greatest extent possible, optimal bids. We introduce a new and general boosting-based algorithm for conditional density estimation problems of this kind, i.e., supervised learning problems in which the goal is to estimate the entire conditional distribution of the real-valued label. This approach is fully implemented as ATTac-2001, a top-scoring agent in the second Trading Agent Competition (TAC-01). We present experiments demonstrating the effectiveness of our boosting-based price predictor relative to several reasonable alternatives.

Modifications of the solutions by numerically motivated alterations of the equations are being reviewed using the examples of magnetic hyperdiffusion and artificial diffusion when advancing the magnetic field in its Euler potential representation. The importance of using integral kernel formulations in mean-field dynamo theory is emphasized in cases where the dynamo growth rate becomes comparable with the inverse turnover time. Finally, the significance of microscopic magnetic Prandtl number in controlling the conversion from kinetic to magnetic energy is highlighted.

The Metric-FF Planning System: Translating "Ignoring Delete Lists" to Numeric State Variables
Creators: name: Hoffmann, J.

Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: Planning with numeric state variables has been a challenge for many years, and was a part of the 3rd International Planning Competition (IPC-3). Currently one of the most popular and successful algorithmic techniques in STRIPS planning is to guide search by a heuristic function, where the heuristic is based on relaxing the planning task by ignoring the delete lists of the available actions. We present a natural extension of ``ignoring delete lists'' to numeric state variables, preserving the relevant theoretical properties of the STRIPS relaxation under the condition that the numeric task at hand is ``monotonic''. We then identify a subset of the numeric IPC-3 competition language, ``linear tasks'', where monotonicity can be achieved by pre-processing. Based on that, we extend the algorithms used in the heuristic planning system FF to linear tasks. The resulting system Metric-FF is, according to the IPC-3 results which we discuss, one of the two currently most efficient numeric planners.

Both bulk magnetization and magnetic torque experiments show a clear signature of the lower critical Hc1 transition, a pronounced difference in zero-field cooled and field cooled branches during temperature sweeps below 6K, and signatures of 1D superconducting fluctuations below ~15-18 K. These experiments extend the magnetic phase diagram we obtained previously by resistive experiments [Z. Wang et al., Phys. Rev.

Developing macro-level collision prediction models to enhance traditional road safety improvement programs and evaluate bicycle safety in the City of Vancouver
Creators: name: Popescu, Bianca
Publisher: name: University of British Columbia
Year: 2016

description: To encourage greener cities while reducing transportation impacts such as climate change, traffic congestion, and road safety issues, governments have been investing in sustainable transportation modes such as cycling. A safe and comfortable cycling environment is critical to encourage bicycle trips, since cyclists are subject to greater safety risks and represent the highest share of severe and fatal road collisions. Traditionally, engineering approaches have addressed road safety in reaction to existing collision histories. For bicycle collisions, which are rare events, a proactive approach is more appropriate. This study described the development of bicycle related macro-level (i.e. neighbourhood or traffic analysis zone level) Collision Prediction Models (CPMs) and tested the models as empirical tools for bicycle road safety evaluation and planning. This study was unique in its usage of the bicycle exposure variable represented by Bicycle Kilometers Travelled (BKT) as a lead exposure variable in the models. The macro-level CPMs that were developed for bicycle-vehicle collisions were applied to a case study of the City of Vancouver at the zonal level. The objectives of the study were to: (1) identify bicycle data safety indicators, (2) develop bicycle macro-level CPMs using generalized linear regression modeling (GLM), (3) demonstrate model use by applying them to a case study of the City of Vancouver through a macro-reactive road safety application, and (4) identify potential safety countermeasures for the highest ranked Collision Prone Zones (CPZs). The models were effective in enhancing traditional road safety initiatives and identifying and ranking dangerous CPZs in the City of Vancouver. The top three collision prone areas were then brought forward for diagnosis and remedy analysis. This case study effectively demonstrated the use of the models to proactively enhance bicycle safety.

These Sun-like stars have well-determined cyclic flux variations similar to 11 yr solar activity cycle. Our flux prediction is based on chromospheric HK emission time series measurements from Mount Wilson Observatory and comparable solar data. We show that solar three - component modeling explains well the stellar observations. We find that the 10 - 20% of K - stars disc surfaces are occupied by bright active regions.

description: Speech recognition and speaker identification are important for authentication and verification in security purpose, but they are difficult to achieve. Speaker identification methods can be divided into text-independent and text-dependent. This paper presents a technique of text-dependent speaker identification using MFCC-domain support vector machine (SVM). In this work, melfrequency cepstrum coefficients (MFCCs) and their statistical distribution properties are used as features, which will be inputs to the neural network. This work firstly used sequential minimum optimization (SMO) learning technique for SVM that improve performance over traditional techniques Chunking, Osuna. The cepstrum coefficients representing the speaker characteristics of a speech segment are computed by nonlinear filter bank analysis and discrete cosine transform. The speaker identification ability and convergence speed of the SVMs are investigated for different combinations of features. Extensive experimental results on several samples show the effectiveness of the proposed approach.

description: We employ 76 type Ia supernovae with optical spectrophotometry within 2.5 days of B-band maximum light obtained by the Nearby Supernova Factory to derive the impact of Si and Ca features on supernovae intrinsic luminosity and determine a dust reddening law. We use the equivalent width of Si II λ4131 in place of light curve stretch to account for first-order intrinsic luminosity variability. The resultant empirical spectral reddening law exhibits strong features associated with Ca II and Si II λ6355. After applying a correction based on the Ca II H&K equivalent width we find a reddening law consistent with a Cardelli extinction law. Using the same input data, we compare this result to synthetic rest-frame UBVRI-like photometry in order to mimic literature observations. After corrections for signatures correlated with Si II λ4131 and Ca II H&K equivalent widths, and introducing an empirical correlation between colors, we determine the dust component in each band. We find a value of the total-to-selective extinction ratio, RV = 2.8 \pm 0.3. This agrees with the Milky Way value, in contrast to the low RV values found in most previous analyses. This result suggests that the long-standing controversy in interpreting SN Ia colors and their compatibility with a classical extinction law, critical to their use as cosmological probes, can be explained by the treatment of the dispersion in colors, and by the variability of features apparent in SN Ia spectra.

Fatherhood

description: The role of fatherhood in communities that experience marginalization is not well understood in academic literature. Further, there is little known about the implementation and evaluation of physical activity programs that are accessible and suitable for fathers who experience income instability, racial discrimination, precarious housing, gender discrimination, and domestic and/or sexualized violence. In this thesis, which is presented in the publishable paper format and is comprised of two papers, I sought to address these gaps. Informed by a constructionist epistemology and an intersectional poststructuralist theoretical framework, in the first paper, I used document analysis and Bacchi and Goodwin’s (2016) “What’s the problem represented to be approach” to investigate how fathers are represented in the program policies of organizations that provide family-centred services in the Downtown Eastside of Vancouver, British Columbia, Canada. In the second paper, guided by the methodological tenets of community-based participatory research, I used semi-structured interviews and critical discourse analysis to better understand how men’s lived experiences as fathers in the Downtown Eastside shaped their participation in Make a Move: Family Walking Program. Taken together, the findings from both papers provide insight into the lived experiences of fathers and the roles that policy and physical activity play in shaping fatherhood in the Downtown Eastside.

description: We present calculations of elliptic flow and azimuthal dependence of correlation radii in the ellipsoidally symmetric generalization of the Buda-Lund hydrodynamic model of hadron production in high-energy nuclear collisions. We compare them to data from RHIC by simultaneous fits to azimuthally integrated invariant spectra of pions, kaons and protons-antiprotons measured by PHENIX in Au+Au reactions at center of mass energy of 200 AGeV. STAR data were used for azimuthally sensitive two-particle correlation function radii and for the transverse momentum dependence of the elliptic flow parameter v2. We have found that the transverse flow is faster in the reaction plane then out of plane, which results in a reaction zone that gets slightly more elongated in-plane than out of plane. The model parameters extracted from the fits are shown and discussed.

description: Hoffmann, a professor and university faculty scholar in the Department of Plant and Microbial Biology, was a presenter in the first lightening round session during the research symposium, and discussed feedback loops between fire, climate, and vegetation. Part of Hoffmann's research seeks to understand the feedback loops between vegetation's modification of microclimates and its influence on the flammability of vegetation. Hoffmann described using a global climate model to examine these processes at the regional scale and how climate changes in relative humidity, rainfall, and wind speed increases fire risk. Another part of Hoffmann's research is studying the ecophysiology of plant responses to fires to better understand how climate and fire interact in vegetation.
Branching out : exploring the stories of female youth in custody

description: Female youth in custody are a marginalized population. The majority of research on the topic of risk factors for female youth in custody is quantitative in nature. There has been a lack of opportunity for female youth in custody to tell their own stories in their own words within a research setting. The primary research question was: What are the stories of female youth in custody? This research question was approached through a post-modernist perspective and used a social constructionist epistemology. A narrative methodology was employed. Participants completed a timeline of life events during a pre-interview, and the timeline was used as an elicitation device during the interview. The interviews were transcribed using Mikel Brown and Gilligan’s (1992) Listener’s Guide. The participants were asked to check their transcribed interviews for completeness and accuracy. The transcribed interviews were analyzed using Braun and Clarke’s (2006) Thematic Analysis Method. Within this method, the findings were coded and seven themes were identified. The themes included: Family Life, Peer Relationships, School Experiences, Substance Use/Mental Health, Childhood Trauma, Misbehaviour/Criminality, and Future Plans. The findings of the research study have provided invaluable information for future prevention efforts for at-risk children. The findings have also helped to inform counselling psychology practice for the population of female youth in custody.

description: Orthogonal Frequency Division Multiplexing (OFDM) is an attractive modulation and multiple access techniques for channels with a nonflat frequency response, as it saves the need for complex equalizers. It can offer high quality performance in terms of bandwidth efficiency, robustness against multipath fading and cost-effective implementation. However, its main disadvantage is the high peak-to-average power ratio (PAPR) of the output signal. As a result, a linear behavior of the system over a large dynamic range is needed and therefore the efficiency of the output amplifier is reduced. In this paper, we investigate the effect of some of these sets of time waveforms on the OFDM system performance in terms of Bit Error Rate (BER). We evaluate the system performance in AWGN channels. The obtained results indicate that the reduction in PAPR of the investigated methods is associated with considerable improvement in BER performance of the system, in multipath channels, as compared to conventional OFDM. These promising results indicate that pulse shaping with reduced PAPR is an attractive solution for an OFDM system.

Reliability analysis of discrete fracture network projections from borehole to shaft scale discontinuity data
Creators: name: Brueckman, Christina
Publisher: name: University of British Columbia

description: When listing the risk factors that may impact the feasibility and success of a block cave operation, Brown (2003) highlights the adequacy of the geotechnical data available as a primary risk. Detailed data on the major structures, rock mass properties, and in situ stresses are necessary to assess the caveability of the orebody, and the excavation stability on the operating levels below, including the potential for fault slip and rockburst hazards when mining in a higher stress environment. The source of this essential data, especially at feasibility-level design, is almost always limited to borehole data. This is emphasized by Laubscher (2000) who notes that most block cave mines are designed solely on borehole data. When restricted to borehole data, significant effort is expended on obtaining oriented core and/or televiewer logs to derive critical data regarding the frequency and orientation of discontinuities and the presence of major faults. Subsequent analysis of the spatial relationships between discontinuities is facilitated by the use of Discrete Fracture Network (DFN) modelling. The value of DFN models for assessing in situ fragmentation and rock mass strength identifies a critical limitation of borehole data. Required DFN inputs include the orientation, intensity, and size distributions of the discontinuities to allow the stochastic generation of a representative fracture network. The evaluation of the discontinuity orientation is relatively easy, intensity or spacing is possible with sufficient effort, but the discontinuity size is not possible given the small “observation window” of a borehole. This thesis reports the results from research carried out to compare analyses of discontinuity data sampled across different spatial scales to improve our understanding and reduce uncertainty in the characterization and projection of discontinuity networks, specifically with respect to fracture spacing and persistence within the rock mass. This work is undertaken using discontinuity data from a deep geotechnical borehole and co-located large diameter shaft. The close proximity of the borehole and shaft provided an opportunity to ground-truth borehole projections based on traditional core logging and televiewer logs. The comparative analysis was completed with the use of DFN modelling. The improved understanding of the spacing and persistence of the discontinuities will aid in further development of guidelines for rapid geotechnical characterization.
The Young Planet-mass Object 2M1207b: a cool, cloudy, and methane-poor atmosphere

description: The properties of 2M1207b, a young (~ 8 Myr) planet-mass companion, have lacked a satisfactory explanation for some time. The combination of low luminosity, red near-IR colors, and L-type near-IR spectrum (previously consistent with Teff ~ 1600K) implies an abnormally small radius. Early explanations for the apparent underluminosity of 2M1207b invoked an edge-on disk or the remnant of a recent protoplanetary collision. The discovery of a second planet-mass object (HR8799b) with similar luminosity and colors as 2M1207b indicates that a third explanation, one of a purely atmospheric nature, is more likely. By including clouds, non-equilibrium chemistry, and low-gravity, an atmosphere with effective temperature consistent with evolution cooling-track predictions is revealed. Consequently, 2M1207b, and others like it, requires no new physics to explain nor do they belong to a new class of objects. Instead they most likely represent the natural extension of cloudy substellar atmospheres down to low Teff and log(g). If this atmosphere only explanation for 2M1207b is correct, then very young planet-mass objects with near-IR spectra similar to field T dwarfs may be rare.

description: This paper introduces a novel method for human face detection with its orientation by using wavelet, principle component analysis (PCA) and redial basis networks. The input image is analyzed by two-dimensional wavelet and a two-dimensional stationary wavelet. The common goals concern are the image clearance and simplification, which are parts of de-noising or compression. We applied an effective procedure to reduce the dimension of the input vectors using PCA. Radial Basis Function (RBF) neural network is then used as a function approximation network to detect where either the input image is contained a face or not and if there is a face exists then tell about its orientation. We will show how RBF can perform well then back-propagation algorithm and give some solution for better regularization of the RBF (GRNN) network. Compared with traditional RBF networks, the proposed network demonstrates better capability of approximation to underlying functions, faster learning speed, better size of network, and high robustness to outliers.

description: Strained Fe-Co films have recently been demonstrated to exhibit a large magnetocrystalline anisotropy (MCA) and thus to be of potential interest as magnetic storage material. Here, we show by means of density-functional (DF) calculations, that chemical order can remarkably enhance the MCA. We also investigate the effect of relaxation perpendicular to the applied strain and evaluate the strain energy as a function of Co concentration and substrate lattice parameter. On this basis, favourable preparation routes for films with a large perpendicular anisotropy are suggested.

Non-thermal processes around accreting galactic black holes

description: Accreting black holes in galactic X-ray sources are surrounded by hot plasma. The innermost part of these systems is likely a corona with different temperatures for ions and electrons. In the so-called low-hard state, hot electrons Comptonize soft X-ray photons from the disk that partially penetrates the corona, producing emission up to $\sim 150$ keV, well beyond the expectations for an optically thick disk of maximum temperature $\sim 10^{7}$ K. However, sources such as Cygnus X-1 produce steady emission up to a few MeV, which is indicative of a non-thermal contribution to the spectral energy distribution. We study the radiative output produced by the injection of non-thermal (both electron and proton) particles in a magnetized corona around a black hole. Energy losses and maximum energies are estimated for all types of particles in a variety of models, characterized by different kinds of advection and relativistic proton content. Transport equations are solved for primary and secondary particles, and spectral energy distributions are determined and corrected by internal absorption. We show that a local injection of non-thermal particles can account for the high energy excess observed in some sources, and we predict the existence of a high-energy bump at energies above 1 TeV, and typical luminosities of $\sim 10^{33}$ erg s$^{-1}$. High-energy instruments such as the future Cherenkov Telescope Array (CTA) can be used to probe the relativistic particle content of the coronae around galactic black holes.

description: The depth profile of the intrinsic magnetic properties in an Fe/Sm-Co bilayer fabricated under nearly optimal spring-magnet conditions was determined by complementary studies of polarized neutron reflectometry and micromagnetic simulations. We found that at the Fe/Sm-Co interface the magnetic properties change gradually at the length scale of 8 nm. In this intermixed interfacial region, the saturation magnetization and magnetic anisotropy are lower and the exchange stiffness is higher than values estimated from the model based on a mixture of Fe and Sm-Co phases. Therefore, the intermixed interface yields superior exchange coupling between the Fe and Sm-Co layers, but at the cost of average magnetization.

Numerical modeling of orthogonal cutting of carbon fibre reinforced polymer composites
Creators: name: Garekani, Amir Hossein Afrasiabi
Publisher: name: University of British Columbia
Year: 2016

description: The focus of this study is on the orthogonal cutting of fibre reinforced composites. A thorough review of the literature is presented in both experimental and numerical work that has thus far been conducted. It is found that in orthogonal cutting of composites, cutting forces, chip formation mechanism and the extent of damage below the cutting plane are highly dependent on the fibre orientation. With fibre orientation increasing from 0° to 90°, cutting forces tend to increase and chips become more dust-like. Two modeling approaches are most commonly adopted for the prediction of force and chip formation, namely the micro-mechanical and the macro-mechanical approach; in the former, the fibre and the matrix are modeled as separate phases and their interface is defined by a traction-separation law. In the latter, the composite is represented by an anisotropic equivalent homogeneous material. It is shown that the numerical predictions are in good agreement with experimental results. With ABAQUS being the most commonly used tool for modeling of composite orthogonal cutting, a two-dimensional macro-mechanical model for cutting of CFRP was created in ABAQUS using Hashin’s damage model. The cutting forces were predicted for fibre orientations of 0°, 30°, 45°, 60°, 90° and 135°. Good prediction of cutting forces with the available experimental data in the literature was obtained. The model however fails to predict the complete chip formation mechanism due to limitations in the material model. A similar model was developed in LS-Dyna using MAT_054 for composites. The cutting forces were found to be sensitive to the damage input parameters, mainly the strain-to-failure of the elements. However, the complete chip formation and chip release was captured in this model which correlated well with the experimental observations. It is suggested that for improved modeling capability, better understanding of the damage behaviour of FRP, especially at the micro-scale is needed. Also, the existing work is found to be limited to orthogonal cutting and drilling separately; it is however worth looking into both items in one study and linking the two processes through a geometric transformation which is the established framework in metal machining.
