The purpose of this study is to identify healthy phenotypes in knee kinematics based on clustering data analysis. Our analysis uses the 3D knee kinematics curves, namely, flexion/extension, abduction/adduction, and tibial internal/external rotation, measured via a KneeKG™ system during a gait task. We investigated two data representation approaches that are based on the joint analysis of the three dimensions. The first is a global approach that is considered a concatenation of the kinematic data without any dimensionality reduction. The second is a local approach that is considered a set of 69 biomechanical parameters of interest extracted from the 3D kinematic curves. The data representations are followed by a clustering process, based on the BIRCH (balanced iterative reducing and clustering using hierarchies) discriminant model, to separate 3D knee kinematics into homogeneous groups or clusters. Phenotypes were obtained by averaging those groups. We validated the clusters using inter-cluster correlation and statistical hypothesis tests. The simulation results showed that the global approach is more efficient, and it allows the identification of three descriptive 3D kinematic phenotypes within a healthy knee population.

Three-dimensional (3D) lower limb kinematic and kinetic analysis based on ambulatory measurements is introduced in this paper. We developed a wireless sensor system composed of a mobile force plate system, 3D motion sensor units and a wireless data logger. 3D motions of body segment and triaxial ground reaction force (GRF) could be simultaneously measured using the system, and the data obtained from sensor units on thighs, shanks and feet could be transferred to a personal computer by wireless local area network (LAN). An inverse dynamics method was adopted to calculate triaxial joint moments. The accuracy of kinematics and kinetics (joint moments) assessment is validated against results obtained from the stationary measurement system based on camera movement analysis and force plates.

Background: Kinematic analysis aimed toward scientific investigation or professional purposes is commonly unaffordable and complex to use. Objective: The purpose of this study was to verify concurrent validation between a cycling-specific 3D camera and the gold-standard 3D general camera systems. Methods: Overall, 11 healthy amateur male triathletes were filmed riding their bicycles with Vicon 3D cameras and the Retul 3D cameras for bike fitting analysis simultaneously. All 18 kinematic measurements given by the bike fitting system were compared with the same data given by Vicon cameras through Pearson correlation (r), intraclass correlation coefficients (ICC), standard error measurements (SEM), and Bland–Altman (BA) analysis. Confidence intervals of 95% are given. Results: A very high correlation between cameras was found on six of 18 measurements. All other presented a high correlation between cameras (between 0.7 and 0.9). In total, six variables indicate a SEM of less than one degree between systems. Only two variables indicate a SEM higher than two degrees between camera systems. Overall, four measures indicate bias tendency according to BA. Conclusions: The cycling-specific led-emitting 3D camera system tested revealed a high or very high degree of correlation with the gold-standard 3D camera system used in laboratory motion capture. In total, 14 measurements of this equipment could be used in sports medicine clinical practice and even by researchers of cycling studies.

Shoulder dysfunctions represent the third musculoskeletal disorder by frequency. However, monitoring the movement of the shoulder is particularly challenging due to the complexity of the joint kinematics. The 3D kinematic analysis with optical motion capture systems (OMCs) makes it possible to overcome clinical tests’ shortcomings and obtain objective data on the characteristics and quality of movement. This systematic review aims to retrieve the current knowledge about using OMCs for 3D shoulder kinematic analysis in patients with musculoskeletal shoulder disorders and their corresponding clinical relevance. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. Studies employing OMCs for 3D kinematic analysis in patients with musculoskeletal shoulder disorders were retrieved. Eleven articles were considered eligible for this study. OMCs can be considered a powerful tool in orthopedic clinical research. The high costs and organizing complexities of experimental setups are likely outweighed by the impact of these systems in guiding clinical practice and patient follow-up. However, additional high-quality studies on using OMCs in clinical practice are required, with standardized protocols and methodologies to make comparing clinical trials easier.

The objective of this study was to assess the precision and accuracy of a nonproprietary, optical three-dimensional (3D) motion analysis system for the simultaneous measurement of soft tissue strains and joint kinematics. The system consisted of two high-resolution digital cameras and software for calculating the 3D coordinates of contrast markers. System precision was assessed by examining the variation in the coordinates of static markers over time. Three-dimensional strain measurement accuracy was assessed by moving contrast markers fixed distances in the field of view and calculating the error in predicted strain. Three-dimensional accuracy for kinematic measurements was assessed by simulating the measurements that are required for recording knee kinematics. The field of view (190 mm) was chosen to allow simultaneous recording of markers for soft tissue strain measurement and knee joint kinematics. Average system precision was between ±0.004 mm and ±0.035 mm, depending on marker size and camera angle. Absolute error in strain measurement varied from a minimum of ±0.025% to a maximum of ±0.142%, depending on the angle between cameras and the direction of strain with respect to the camera axes. Kinematic accuracy for translations was between ±0.008 mm and ±0.034 mm, while rotational accuracy was ±0.082 deg to ±0.160 deg. These results demonstrate that simultaneous optical measurement of 3D soft tissue strain and 3D joint kinematics can be performed while achieving excellent accuracy for both sets of measurements.

This paper presents a cost- and time-effective wearable inertial sensor system, the InertialLAB. It includes gyroscopes and accelerometers for the real-time monitoring of 3D-angular velocity and 3D-acceleration of up to six lower limbs and trunk segment and sagittal joint angle up to six joints. InertialLAB followed an open architecture with a low computational load to be executed by wearable processing units up to 200 Hz for fostering kinematic gait data to third-party systems, advancing similar commercial systems. For joint angle estimation, we developed a trigonometric method based on the segments’ orientation previously computed by fusion-based methods. The validation covered healthy gait patterns in varying speed and terrain (flat, ramp, and stairs) and including turns, extending the experiments approached in the literature. The benchmarking analysis to MVN BIOMECH reported that InertialLAB provides more reliable measures in stairs than in flat terrain and ramp. The joint angle time-series of InertialLAB showed good waveform similarity (>0.898) with MVN BIOMECH, resulting in high reliability and excellent validity. User-independent neural network regression models successfully minimized the drift errors observed in InertialLAB’s joint angles (NRMSE < 0.092). Further, users ranked InertialLAB as good in terms of usability. InertialLAB shows promise for daily kinematic gait analysis and real-time kinematic feedback for wearable third-party systems.

Forward kinematics is one of the main research fields in robotics, where the goal is to obtain the position of a robot’s end-effector from its joint parameters. This work presents a method for achieving this using a recursive algorithm that builds a 3D computational model from the configuration of a robotic system. The orientation of the robot’s links is determined from the joint angles using Euler Angles and rotation matrices. Kinematic links are modeled sequentially, the properties of each link are defined by its geometry, the geometry of its predecessor in the kinematic chain, and the configuration of the joint between them. This makes this method ideal for tackling serial kinematic chains. The proposed method is advantageous due to its theoretical increase in computational efficiency, ease of implementation, and simple interpretation of the geometric operations. This method is tested and validated by modeling a human-inspired robotic mobile manipulator (CHARMIE) in Python.

Purpose: dinamic roentgen stereophotogrammetric analysis (RSA), a technique currently based only on customized radiographic equipment, has been shown to be a very accurate method for detecting threedimensional (3D) joint motion. The aim of the present work was to evaluate the applicability of an innovative RSA set-up for in vivo knee kinematic analysis, using a biplane fluoroscopic image system. To this end, the Authors describe the set-up as well as a possible protocol for clinical knee joint evaluation. The accuracy of the kinematic measurements is assessed. Methods: the Authors evaluated the accuracy of 3D kinematic analysis of the knee in a new RSA set-up, based on a commercial biplane fluoroscopy system integrated into the clinical environment. The study was organized in three main phases: an in vitro test under static conditions, an in vitro test under dynamic conditions reproducing a flexion-extension range of motion (ROM), and an in vivo analysis of the flexionextension ROM. For each test, the following were calculated, as an indication of the tracking accuracy: mean, minimum, maximum values and standard deviation of the error of rigid body fitting. Results: in terms of rigid body fitting, in vivo test errors were found to be 0.10±0.05 mm. Phantom tests in static and kinematic conditions showed precision levels, for translations and rotations, of below 0.1 mm/0.2º and below 0.5 mm/0.3º respectively for all directions. Conclusions: the results of this study suggest that kinematic RSA can be successfully performed using a standard clinical biplane fluoroscopy system for the acquisition of slow movements of the lower limb. Clinical relevance: a kinematic RSA set-up using a clinical biplane fluoroscopy system is potentially applicable and provides a useful method for obtaining better characterization of joint biomechanics.

As an important mechanism with intermittent motion, the globoidal indexing cam is always a research hot in the mechanical fields. The working profile of globoidal indexing cam is extremely complicated and undevelopable, which make it quite difficult to be protracted by the conventional drafting method. Aiming at this problem, the working curvilinear equation of the intermittent motion of an indexing cam is derived based on the RPY (Roll-Pitch-Yaw) coordinate transformation method. The 3D model based on the curvilinear equation is built by the Creo2.0 modeling software. The virtual prototype is established based on the ADAMS software, while the kinematics simulation is implemented. The success of virtual simulation verifies the correctness of curvilinear equation. The numerical results, presented and discussed in the paper, indicate that the proposed model is feasible to foresee the kinematic behaviour of an actual system.

Analysis of kinematic and postural data of adolescent idiopathic scoliosis (AIS) patients seems relevant for a better understanding of biomechanical aspects involved in AIS and its etiopathogenesis. The present project aimed at investigating kinematic differences and asymmetries in early AIS in a static task and in uniplanar trunk movements (rotations, lateral bending, and forward bending). Trunk kinematics and posture were assessed using a 3D motion analysis system and a force plate. A total of fifteen healthy girls, fifteen AIS girls with a left lumbar main curve, and seventeen AIS girls with a right thoracic main curve were compared. Statistical analyses were performed to investigate presumed differences between the three groups. This study showed kinematic and postural differences between mild AIS patients and controls such as static imbalance, a reduced range of motion in the frontal plane, and a different kinematic strategy in lateral bending. These differences mainly occurred in the same direction, whatever the type of scoliosis, and suggested that AIS patients behave similarly from a dynamic point of view.

Aim The aim of the study was to examine the differences between able-bodied athletes (AB) and three para-athlete (PA) classes in three-dimensional range of motion (RoM) for the major joints of the body, and to define which joint angles are correlated with power output during paddling on a kayak ergometer. An additional aim was to validate three new classification tests used in classification of Paracanoe athletes. This study was an integral part of developing a new evidence-based classification system for Paracanoe which was accepted by the International Paralympic Committee in 2015. Method 41 PA (13 F and 28 M; 35 ± 9.0 years, 70.6 ± 12.5 kg, 1.74 ± 0.12 m) and 10 AB (4 F and 6 M; 22 ± 3.5 years, 78.3 ± 10.2 kg, 1.79 ± 0.06 m) participated in the study. Three-dimensional kinematic data was recorded using an optoelectronic system containing 12 infrared cameras capturing reflective markers placed on the participants, the paddle and on the force transducers. Force was measured at the paddle to enable calculations of power output. The kinematic and kinetic data were collected during paddling on the kayak ergometer at incremental intensities starting at a low intensity level (50 W). The athletes then increased intensity with 50 W up to a high intensity level which was defined as the highest level the athlete could maintain with good technique for 20 stroke cycles. The athletes were then asked to paddle at a maximal level. The kinematic and kinetic data were imported into Visual 3D and MATLAB where all calculations were made. Results There were significant differences between the AB and the three PA classes for joint angles in the shoulder (e.g. flexion/extension and internal/external rotation, AB>PA), trunk (trunk rotation and trunk flexion, AB>PA) and leg (hip, knee and ankle flexion AB>PA) during paddling. Significant positive correlations were seen for both men and women between power output and trunk rotation RoM, hip, knee and ankle flexion RoM and in maximal trunk flexion during paddling. A positive correlation was also seen between the newly developed classification tests and the RoM values and power output. Conclusion This study showed that the RoM of the trunk and legs are positively correlated with power output during paddling on a kayak ergometer and that there is a significant difference between the AB and the PA classes in trunk and leg RoM. The results also showed that the newly developed classification tests are valid tests to use in classification of Paracanoe athletes.
Syfte och frågeställningar Syftet med studien var att undersöka skillnaderna mellan icke funktionsnedsatta idrottare (AB) och tre klasser av funktionsnedsatta idrottare (PA) i tredimensionellt rörelseomfång (RoM) i samtliga större leder i kroppen, och att definiera vilka leder som korrelerade med power output vid paddling på kajak ergometer. Ett ytterligare syfte var att validera tre nya klassificeringstester för klassificering i Parakanot. Denna studie var en viktig del vid utvecklingen av ett nytt evidensbaserat klassificeringssystem för Parakanot vilket blev accepterat av Internationella Paralympiska Kommitteen under 2015. Metod 41 PA (13 K och 28 M; 35 ± 9.0 år, 70.6 ± 12.5 kg, 1.74 ± 0.12 m) och 10 AB (4 K och 6 M; 22 ± 3.5 år, 78.3 ± 10.2 kg, 1.79 ± 0.06 m) deltog i studien. Tredimensionell kinematisk data samlades in med ett optoelektroniskt system innehållandes 12 infraröda kameror som registrerade reflekterande markörer som var fäst på försökspersonerna, på paddeln och på kraftgivarna. Kraft mättes vid paddeln vilket möjliggjorde beräkning av power output. Den kinematiska och kinetiska datan samlades in vid paddling på kajak ergometer på olika intensitetsnivåer och idrottarna startade på en låg intensitetsnivå (50 W). Idrottarna ökade sedan intensitet med 50 W upp till en hög intensitet vilket definierades som den högsta nivån som idrottarna kunde paddla stabilt på med bra teknik i 20 drag cykler. Idrottarna paddlade sedan på en maximal nivå. Den kinematiska och kinetiska datan importerades sedan till Visual3D och MATLAB där alla beräkningar utfördes. Resultat Det fanns en signifikanta skillnader mellan AB och de tre PA klasserna för ledvinklarna i skuldran (flexion/extension och inåt/utåt rotation, AB>PA), bålen (bål rotation och bål flexion, AB>PA) och i benen (höft, knä och ankel flexion, AB>PA) vid paddling. Det fanns en signifikant positiv korrelation för både män och kvinnor mellan power output och RoM i bål rotation, höft, knä och ankel flexion och i maximal bål flexion vid paddling. En positiv korrelation fanns även mellan de nyutvecklade klassificeringstesterna och RoM värdena samt power output. Slutsats Studien visade att bål- och benrörelsen är positivt korrelerat med power output vid paddling på kajak ergometer och att det är en signifikant skillnad mellan AB och PA klasserna i bål och ben RoM. Resultaten visade också att de nyutvecklade klassificeringstesterna är valida tester för användning inom klassificering av Parakanotister.

The main objective of this study was to determine differences, if any, in three-dimensional (3D) kinematic characteristics of the three principal punches (the jab, hook and uppercut) executed by novice, intermediate and elite level amateur boxers. Specifically, the kinematic variables related to the displacement, linear velocity and acceleration of the upper body segments, translational hand acceleration and vertical ground reaction force generated by boxers were analyzed. The subjects of this study composed of 10 novice, 9 intermediate, and 11 elite level amateur boxers. Ages of the subjects ranged from 18 to 34 years old. All subjects executed their punches toward a head-high target on a standard practice bag. The motions were captured with PhaseSpace real time optical tracking system with 8 high speed cameras at 240 fps. Then, the motions captured were analyzed to quantify the kinematic factors associated with each punch. The results showed that the uppercut punch generated larger linear shoulder, elbow and wrist velocity compared to the jab punch. Similarly, the uppercut punch generated larger linear shoulder, elbow and wrist acceleration compared to the hook and jab punches. Moreover, the uppercut and hook punches generated larger translational hand acceleration compared to the jab punch. As a conclusion, the results for all kinematic variables demonstrated that the type of punch executed was the major determinant of the magnitude of each factor studied. Moreover, the technique employed can significantly affect the resulting displacement, linear velocity and acceleration, and translational hand acceleration of the fist.

I had the opportunity to develop my thesis during the Internship Program at F.lli Righini, a world leader in designing and manufacturing offshore equipment. I was tasked with improving the mechanical efficiency of an umbilical lay system. Instead of laying the cable on the sea floor, the Client wished to have it partially floating. A new system had to be devised whereby a number of buoyancy modules had to be installed on the cable itself, an operation complicated by the fact that it could not be performed by a traditional fixed chute. To solve this challenge, Righini suggested an innovative kinematic chute able to perform a certain rotation, thereby fully satisfying the requisites. The aim of this master thesis is to optimize this prototype system. A MATLAB code will be created to conduct a meticulous structural analysis of the kinematic chute, to see if the piston which activates the whole chute rotation can be optimized in terms of weight and cost.

Turnout, the act of externally rotating the legs, is produced through the summation of joint structure characteristics and ranges of motion at the hip, knee, ankle and foot. The hip joint’s contribution to functional turnout, a dancer’s preferred turnout stance, has received extensive examination, whereas little is known about below-the-hip contributions. Dancers with limited hip external rotation (HER) are associated with an increased risk of overuse lower limb injury. These injuries have been attributed to forcing turnout via additional external tibiofemoral rotation (TFR) and foot pronation. Yet knowledge of these compensatory mechanisms is based on biomechanical theories and clinical observations rather than quantitative clinical assessments or 3D motion analysis. The principal aim of this research was to investigate the lower leg and foot contributions to turnout in university-level female dancers using quantitative clinical assessments and 3D motion analysis, as well as the compensations mechanisms dancers use to increase turnout. The first study focused on assessing the lower leg and foot contributions to turnout using the clinical assessments of passive TFR and active measures of foot pronation in turnout. The results showed dancers assumed a more pronated posture in turnout, and those with a greater passive TFR demonstrated a less pronated position in turnout providing new insight into the mechanical coupling between the foot and the tibiofemoral joint in dancers. The purpose of the second study was to use 3D kinematic analyses to determine the lower leg and foot compensations that dancers use to accentuate their turnout. Active and passive TFR of the dancers was also measured. The results demonstrated foot abduction was the strongest predictor of functional and forced turnout, compared to both the hip and knee external rotation. A moderate-strong negative relationship was observed between HER and foot abduction in all turnout conditions. A moderate negative relationship was found between the passive TFR and foot abduction in all turnout conditions. These findings indicate clinical measures of external tibiofemoral rotation can predict the total below-hip compensation mechanisms a dancer uses to achieve turnout. Suggesting, dancers are more likely to pronate about the foot/ankle complex, than rotate at the knee to compensate for limited HER. Whereas dancers with less foot mobility may force additional rotation via the knee which may contribute to rotational knee joint laxity. The previous study provided the rational for an in-depth analysis of the foot/ankle complex such as that provided by three-dimensional multi-segment foot models (3DMFMs). The lack of an appropriate model for ballet dancers led to the modification of the Rizzoli Foot Model. Kinematic repeatability of the model was determined from analysing ballet dancers performing the following movements; parallel stance, turnout plié, turnout stance, turnout rise and flex-point-flex. First metatarsophalangeal joint (MTPJ) in the sagittal plane demonstrated excellent intra and inter-assessor repeatability across all movements. All inter-segmental angles except for the tibia-hindfoot and hindfoot-midfoot frontal planes demonstrated excellent intra-assessor repeatability during flex-point-flex movements. Providing a reliable method to measure 3D foot/ankle complex can enable a deeper understanding of the foot/ankle complex contribution to turnout. Previous 3DMFM used in dance science consisted of only two foot segments, hindfoot and forefoot whereas this model includes a midfoot segment which is important as forefoot abduction has been suggested to give the illusion of a larger turnout angle. The final study aimed to examine the lower leg and foot compensations that dancers use to accentuate their turnout using a dance specific 3DMFM. Hindfoot abduction and eversion were the strongest predictors of foot abduction in turnout. Midfoot abduction was significantly greater in forced turnout compared to functional turnout. No significant differences were found for forefoot abduction, first MTPJ abduction and navicular drop in functional or forced turnout, compared to natural stance. Foot pronation does play a role in achieving turnout and there may be a safe range of pronation. However, the amount of detrimental pronation for a dancer is unknown. The overall results from these studies offer compelling evidence that the foot/ankle complex plays a more important role in achieving turnout, than previously thought. Further prospective research on in situ measures of the lower leg and foot in turnout and injury surveillance are required to improve our understanding of the normal and abnormal dance biomechanics.

Dynamic transperineal ultrasound (TPUS) video allows for kinematic analysis of urogenital morphology and mobility, however, measures are often limited to peak displacements of anatomical landmarks and are vulnerable to error incurred by probe rotation during imaging. This thesis aimed to (1) develop an algorithm to calculate kinematic curves of urogenital landmark motion from TPUS video and to (2) investigate the error incurred in these kinematic measures due to in-plane ultrasound probe rotation. UROKIN, a semi-automated software, was developed and, as a proof of concept, was used to identify differences in urogenital kinematics during pelvic floor muscle maximum voluntary contractions between women with and without stress urinary incontinence. A mathematical model revealed that the error incurred by TPUS probe rotation in the x- (anterior-posterior) and y- (cranial-caudal) directions, was a factor of: r, the radius of rotation; Ɵ, the in-plane angular probe rotation; and α, the angular deviation between the anatomical planes and the coordinate system in which error was calculated. As an absolute measure, the error incurred by in-plane probe rotation is reduced to a factor of only r and Ɵ. Moving forward, UROKIN must be adapted to include findings from (1), and must be tested for validity and reliability.

Finding patterns in biomolecular data, particularly in DNA and RNA, is at the center of modern biological research. These data are complex and growing rapidly, so the search for patterns requires increasingly sophisticated computer methods. Pattern Discovery in Biomolecular Data provides a clear, up-to-date summary of the principal techniques. Each chapter is self-contained, and the techniques are drawn from many fields, including graph theory, information theory, statistics, genetic algorithms, computer visualization, and vision. Since pattern searches often benefit from multiple approaches, the book presents methods in their purest form so that readers can best choose the method or combination that fits their needs. The chapters focus on finding patterns in DNA, RNA, and protein sequences, finding patterns in 2D and 3D structures, and choosing system components. This volume will be invaluable for all workers in genomics and genetic analysis, and others whose research requires biocomputing.

The quality of data collected in official spatial databases is crucial in making strategic decisions as well as in the implementation of planning and design works. Awareness of the level of the quality of these data is also important for individual users of official spatial data. The author presents methods and models of description and evaluation of the quality of spatial data collected in public registers. Data describing the space in the highest degree of detail, which are collected in three databases: land and buildings registry (EGiB), geodetic registry of the land infrastructure network (GESUT) and in database of topographic objects (BDOT500) were analyzed. The results of the research concerned selected aspects of activities in terms of the spatial data quality. These activities include: the assessment of the accuracy of data collected in official spatial databases; determination of the uncertainty of the area of registry parcels, analysis of the risk of damage to the underground infrastructure network due to the quality of spatial data, construction of the quality model of data collected in official databases and visualization of the phenomenon of uncertainty in spatial data. The evaluation of the accuracy of data collected in official, large-scale spatial databases was based on a representative sample of data. The test sample was a set of deviations of coordinates with three variables dX, dY and Dl – deviations from the X and Y coordinates and the length of the point offset vector of the test sample in relation to its position recognized as a faultless. The compatibility of empirical data accuracy distributions with models (theoretical distributions of random variables) was investigated and also the accuracy of the spatial data has been assessed by means of the methods resistant to the outliers. In the process of determination of the accuracy of spatial data collected in public registers, the author’s solution was used – resistant method of the relative frequency. Weight functions, which modify (to varying degree) the sizes of the vectors Dl – the lengths of the points offset vector of the test sample in relation to their position recognized as a faultless were proposed. From the scope of the uncertainty of estimation of the area of registry parcels the impact of the errors of the geodetic network points was determined (points of reference and of the higher class networks) and the effect of the correlation between the coordinates of the same point on the accuracy of the determined plot area. The scope of the correction was determined (in EGiB database) of the plots area, calculated on the basis of re-measurements, performed using equivalent techniques (in terms of accuracy). The analysis of the risk of damage to the underground infrastructure network due to the low quality of spatial data is another research topic presented in the paper. Three main factors have been identified that influence the value of this risk: incompleteness of spatial data sets and insufficient accuracy of determination of the horizontal and vertical position of underground infrastructure. A method for estimation of the project risk has been developed (quantitative and qualitative) and the author’s risk estimation technique, based on the idea of fuzzy logic was proposed. Maps (2D and 3D) of the risk of damage to the underground infrastructure network were developed in the form of large-scale thematic maps, presenting the design risk in qualitative and quantitative form. The data quality model is a set of rules used to describe the quality of these data sets. The model that has been proposed defines a standardized approach for assessing and reporting the quality of EGiB, GESUT and BDOT500 spatial data bases. Quantitative and qualitative rules (automatic, office and field) of data sets control were defined. The minimum sample size and the number of eligible nonconformities in random samples were determined. The data quality elements were described using the following descriptors: range, measure, result, and type and unit of value. Data quality studies were performed according to the users needs. The values of impact weights were determined by the hierarchical analytical process method (AHP). The harmonization of conceptual models of EGiB, GESUT and BDOT500 databases with BDOT10k database was analysed too. It was found that the downloading and supplying of the information in BDOT10k creation and update processes from the analyzed registers are limited. An effective approach to providing spatial data sets users with information concerning data uncertainty are cartographic visualization techniques. Based on the author’s own experience and research works on the quality of official spatial database data examination, the set of methods for visualization of the uncertainty of data bases EGiB, GESUT and BDOT500 was defined. This set includes visualization techniques designed to present three types of uncertainty: location, attribute values and time. Uncertainty of the position was defined (for surface, line, and point objects) using several (three to five) visual variables. Uncertainty of attribute values and time uncertainty, describing (for example) completeness or timeliness of sets, are presented by means of three graphical variables. The research problems presented in the paper are of cognitive and application importance. They indicate on the possibility of effective evaluation of the quality of spatial data collected in public registers and may be an important element of the expert system.

The paper presents a novel technique for the kinematic analysis of a geared mechanism manufactured through 3D printing technology. In the syllabus of the undergraduate 3D Printing course, one of the student projects is to manufacture a spur Norton type gear box which includes a planetary mechanism for engaging its three planets, thus three output velocities for the gear box are obtained. The connected elements (carriers, gears, planets) are fabricated without any involvement of assembly operation. At the prototype stage, a CAD model of the mechanism is created and a search for abilities and limitations of the mechanism are required. The analysis of abilities of motion includes determination of mechanism mobility (DOF). A step by step simple technique is presented for determination of the rank for the matrix of coefficients from the kinematic equations. Thus, the DOF is the difference between the number columns and the rank previously determined. The steps required in the analysis are: numbering of links and joints, graph attached to mechanism, matrix of incidence cycles-nodes in graph, and determination of its rank by using Mathematica commands. For the set of base cycles are automatically generated independent scalar equations. The matrix, denoted velocity matroidal, has the coefficients for the mechanism’s unknown absolute angular velocities-determined based on an analogy to a system of parallel forces from static equilibrium, angular velocities being considered analog to the “forces“. The relations between the input-output links’ absolute angular velocities are determined. The coefficients in the kinematic equations for velocities are written as function of gear ratios. The number of gear teeth can be selected also for the desired input-output speed ratios.

The use of parallel kinematic structures allows to design light manipulators with higher dynamic performance with respect to serial robots. In this work, the issue of accurately modelling the dynamics of lightweight flexible-link parallel robots has been investigated. The Equivalent Rigid-Link System (ERLS) formulation, useful for describing the dynamic evolution of 3D serial robots with flexible-links, has been extended to Parallel-Kinematic-Machines (PKM) both from the theoretical and from the software implementation points of view. Standard robotics concepts of 3D kinematics are exploited to formulate and solve the ERLS kinematics, thus allowing to easily work with this formulation. A simulator, capable of predicting the deformations due to the elasticity of the links, has been developed and some industrial case-studies have been implemented to validate it. The formulation and the developed simulator will give the opportunity to extensively study the deformations of parallel manipulators, allow to predict the vibrations of the system, and, then, compensate them.

The Articulated Wheeled Vehicle (AWV) paradigm examines a class of wheeled vehicles where the chassis is connected via articulated chains to a set of ground-contact wheels. Actively- or passively-controlled articulations can help alter wheel placement with respect to chassis during locomotion, endowing the vehicle with significant reconfigurability and redundancy. The ensuing ‘leg-wheeled’ systems exploit these capabilities to realize significant advantages (improved stability, obstacle surmounting capability, enhanced robustness) over both traditional wheeled- and/or legged-systems in a range of uneven-terrain locomotion applications. In our previous work, we exploited the reconfiguration capabilities of a planar AWR to achieve internal shape regulation, secondary to a trajectory-following task. In this work, we extend these capabilities to the full 3D case — in order to utilize the full potential of kinematic- and actuation-redundancy to enhance rough-terrain locomotion.

In this paper, an effective method in dynamic modeling of spatial flexible-link robots under large displacements and small deformations is discussed and a generic Matlab™ software simulator based on it is presented and validated. The adopted method is based on an Equivalent Rigid Link System (ERLS) that enables to decouple the kinematic equations of the ERLS from the compatibility equations of the displacements at the joints allowing an easy and recursive procedure to build the robot dynamic matrices. The simulator is suitable for dynamic modelling of generic 3D serial flexible-link robots. The Matlab™ software simulator is validated with respect to the Adams-Flex™ commercial software, which implements Floating Frame of Reference (FFR) formulation, one of the most used methods for dynamic modeling of multibody flexible-link mechanisms with large displacements and small deformations.

This paper introduces MBSVT (Multibody Systems at Virginia Tech), as a software library for the kinematic and dynamic simulation of multibody systems, with forward kinematics and dynamics, direct and adjoint sensitivity analysis, and optimization capabilities. The MBSVT software was developed in Fortran 2003 as a collection of Fortran modules and it was tested on several different platforms using multiple compilers. The kinematic library includes dot-1 constraint, revolute, spherical, Euler, and translational joints, as well as distance and coordinates driving constraints. The forward dynamics uses the penalty formulation to write the equations of motion and both explicit and implicit Runge-Kutta numerical integrators are implemented to integrate the equations. The library implements external forces, such as translational spring-damper-actuator, bump stop, linear normal contact, and basic tire force. Direct and adjoint sensitivity equations are implemented for the penalty formulation. The L-BFGS-B quasi-Newton optimization algorithm [1] is integrated with the library, to carry out the optimization tasks. MBSVT also provides a connection with Matlab by means of the Matlab engine. 3D rendering is available via the graphic library MBSVT-viz based on OpenSceneGraph. The collection of benchmark problems provided includes a crank-slider mechanism, 2D and 3D excavators models, a vehicle suspension, and full vehicle model. The distribution includes a Cmake list, gfortran make files, MSV2010 project files, and a collection of training problems. Detailed doxygen documentation for the MBSVT library is available in html and pdf formats.

Abstract This paper presents a systematic rapid creative design framework for complex mechanisms to support creative conceptual design schemes’ generation and 3D virtual simulation. In conceptual design stage, a rule-based creative conceptual design system is constructed to expand conceptual design solution space through operating design rules related to functional requirements of design problems with graphic carriers. Compared with FBS models or catalogue-based matching approaches, the rule-based system can dig out more innovative conceptual design schemes including generalized mechanisms. Then a great number of conceptual design schemes generated in conceptual design are represented with symbolic schemes and identified into constituent basic mechanisms and their connections. To the constituent basic mechanisms, the object-oriented (OO) technology is applied to set up their 3D virtual solid models with encapsulated key feature parameters, which can be automatically modified by system’s database with the aid of the new defined classes. According to the OO solid models of constituent basic mechanisms and their connections, a 3D space layout algorithm considering the connections among the solid models is developed to determine the position of each constituent solid basic mechanism. Finally, an object-oriented based kinematic analysis method is pro-posed to carry out automatic kinematic analysis of the complex mechanisms related to the symbolic schemes. By means of the virtual-assembly approach and the kinematic data, all constituent components in the complex mechanisms are put onto the proper positions as they are assembled manually. In this way, the systematic design processes for complex mechanisms from creative conceptual design schemes’ generation, to 3D virtual solid design, layout de-sign, kinematic analysis, and virtual assembly and simulation are realized automatically. Based on the framework presented in this paper, rapid generating and evaluating innovative, excellent-performance schemes of complex mechanisms in 3D virtual prototype form are possible.

In this paper, the possibilities of using augmented reality technology are analyzed and the software model of the solar system model is created. The analysis of the available software products modeling the solar system is carried out. The developed software application demonstrates the behavior of solar system objects in detail with augmented reality technology. In addition to the interactive 3D model, you can explore each planet visually as well as informatively – by reading the description of each object, its main characteristics, and interesting facts. The model has two main views: Augmented Reality and 3D. Real-world object parameters were used to create the 3D models, using the basic ones – the correct proportions in the size and velocity of the objects and the shapes and distances between the orbits of the celestial bodies.

Rapid technological innovation is reshaping the UK food system in many ways. FSA needs to stay abreast of these changes and develop regulatory responses to ensure novel technologies do not compromise food safety and public health. This report presents a rapid evidence assessment of the emerging technologies considered most likely to have a material impact on the UK food system and food safety over the coming decade. Six technology fields were identified and their implications for industry, consumers, food safety and the regulatory framework explored. These fields are: Food Production and Processing (indoor farming, 3D food printing, food side and byproduct use, novel non-thermal processing, and novel pesticides); Novel Sources of Protein, such as insects (for human consumption, and animal feedstock); Synthetic Biology (including lab-grown meat and proteins); Genomics Applications along the value chain (for food safety applications, and personal “nutrigenomics”); Novel Packaging (active, smart, biodegradable, edible, and reusable solutions); and, Digital Technologies in the food sector (supporting analysis, decision making and traceability). The report identifies priority areas for regulatory engagement, and three major areas of emerging technology that are likely to have broad impact across the entire food industry. These areas are synthetic biology, novel food packaging technologies, and digital technologies. FSA will need to take a proactive approach to regulation, based on frequent monitoring and rapid feedback, to manage the challenges these technologies present, and balance increasing technological push and commercial pressures with broader human health and sustainability requirements. It is recommended FSA consider expanding in-house expertise and long-term ties with experts in relevant fields to support policymaking. Recognising the convergence of increasingly sophisticated science and technology applications, alongside wider systemic risks to the environment, human health and society, it is recommended that FSA adopt a complex systems perspective to future food safety regulation, including its wider impact on public health. Finally, the increasing pace of technological

This work aims to understand the processes that have taken part in the deformation, both on a small and large scale, of metamorphic materials in Valdemorillo area, located in the west of the Community of Madrid and within the Spanish Central System. The objective is to understand the kinematic evolution and the specific mechanical behaviour of igneous-metamorphic materials from the area, deformed by certain efforts developed throughout the Hercynian Orogeny. Therefore, a structural analysis has been carried out throughout a geological mapping scaled 1: 25000 and the analysis of various petrographic studies by microscope. Thus, a total of 5 different deformations have been identified, which have allowed us to better understand the reconstruction of the processes generated in these materials and that we see today.

These high-accuracy, coregistered data produced a 3-D model with assigned temperature values for measured surfaces, useful in identifying thermal anomalies and areas for potential improvements and for assessing building and utilidor infrastructure by locating and quantifying areas settlement and structural anomalies. The ground-based survey of the Crary Lab was similar to previous work performed by the team at both Palmer (2015) and South Pole (2017) Stations. The UAS platform focused on approximately 10,500 linear-feet of utilidor throughout McMurdo Station. The datasets of the two survey areas overlapped, allowing us to combine them into a single, georeferenced 3-D model of McMurdo Station. Coincident exterior temperature and atmospheric measurements and Global Navigation Satellite System real-time kinematic surveys provided further insights. Finally, we assessed the thermal envelope of the Crary Lab and the structural features of the utilidor. The resulting dataset is available for analysis and quantification.

The need to conduct complex operations over time results in U.S. forces remaining in deployed locations for long periods. In such cases, more sustainable facilities are required to better accommodate and protect forward deployed forces. Current efforts to develop safer, more sustainable operating facilities for contingency bases involve construction activities that redesign the types and characteris-tics of the structures constructed, reduce the resources required to build, and reduce resources needed to operate and maintain the com-pleted facilities. The Automated Construction of Expeditionary Structures (ACES) project was undertaken to develop the capability to “print” custom-designed expeditionary structures on demand, in the field, using locally available materials with the minimum number of personnel. This work investigated large-scale automated “additive construction” (i.e., 3D printing with concrete) for construction applications. This document, which documents ACES energy and modeling, is one of four technical reports, each of which details a major area of the ACES research project, its research processes, and associated results, including: System Requirements, Construction, and Performance; Energy and Modeling; Materials and Testing; Architectural and Structural Analysis.
