Abstract:
Abstract Background: Deep brain stimulation (DBS) surgery has an average accuracy of 2 to 3 mm (range, 0-6 mm). Intraoperative detection of track location may be useful in interpreting physiological results and thus limit the number of brain penetrations as well as decrease the incidence of reoperations. The O-arm has been used to identify the DBS lead position; however, early results have indicated a significant discrepancy with lead position on postoperative imaging. Objective: This prospective study was conducted to determine the accuracy and reliability of fiducial and track localization and to assess the accuracy of O-arm image– based registration. The computed tomography (CT) image was considered the gold standard, and so for this study, the locations of all objects on the O-arm image were compared with their CT location. Methods: Thirty-three DBS surgeries were performed using the O-arm to image each track with detailed analysis of fiducial and track localization accuracy. Twenty-one subsequent surgeries were performed using O-arm registration. Only the final lead position was assessed in these individuals. Results: The measurement error of the system was 0.7 mm, with a maximum error of 1.9 mm. Twenty-two percent of the parallel tracks through the BenGun exceeded this error and demonstrated the ability of the O-arm to detect these skewed tracks. The accuracy of final lead position was 2.04 mm in procedures with registration based on an O-arm image. This was not significantly different from CT-based registration at 2.16 mm. Conclusion: The O-arm was able to detect skewed tracks and provide registration accuracy equivalent to a CT scan.

Abstract:
In order to explore the kinematics and muscle force characteristics of competitive Taijiquan arm manipulation, and solve the problems of arm trajectory and control in the process of manipulation, this study puts forward the sports biomechanical analysis of arm manipulation in competitive Taijiquan. The technical characteristics and muscle force characteristics of 15 athletes from the competitive Taijiquan team of Xi’an Institute of physical education were studied. Use Excel 2007 and SPSS17.0 to statistically analyze and process the original data. According to the actual needs, the data indicators are summarized. The combined movements of competitive Taijiquan arm manipulation are captured through high-speed photography, and the kinematic data are statistically analyzed, mainly from the two aspects of action amplitude change and action braking. The results show the action track length, relative track length, and action track length of each plane of the two combined hands. The order of the two combined action tracks is: combination 1 > combination 2, in which the action track in the sagittal plane is the longest in combination 1, and it can also be considered that the motion amplitude in the sagittal plane is the largest in combination 1. The average acceleration of group A in the first beat is 0.51 m/s2 smaller than that of group B, and the value is 0.22 m/s2 smaller. Therefore, the deceleration of group A is larger than that of group B, and the braking capacity of group A is slightly stronger than that of group B. In the second beat, the average acceleration of group B is 1.5722 m/s2 larger than that of group A, and the value is 0.210 m/s2 larger. The average acceleration of group A in the third, fourth, fifth, and sixth beats is 0.9, 3.728, 0.57, and 0.837 m/s2 smaller than that of group B, and the values are 0.466, 0.174, 0.250, and 0.003 m/s2 smaller, indicating that the braking capacity of group A in the third, fourth, fifth, sixth, and eighth beats is slightly stronger than that of group B. In the braking of each beat in combination 1 and combination 2 of group AB, the braking ability of arm manipulation of group A is stronger than that of group B. In competitive Taijiquan, the movement techniques of manipulation include: bouncing technology, braking technology, and control technology. For arm manipulation, athletes should have the ability of “braking” technology. In the correlation analysis of movement track length, RMS and I EMG, the score of athletes in group A is high, and there is no correlation between movement track length and RMS. There is a significant correlation between RMS and movement track length in group B, and the correlation degree is moderate. This shows that when the movement of group B athletes is completed, the muscles are in a state of tension, the movement skills are not mastered well, and the energy saving is not achieved. During training, we should pay more attention to the proprioception of muscles and form a correct way of muscle exertion.

This paper presents a new gesture track recognition method based on the depth image information received from the Kinect sensor. First, a Kinect sensor is used to obtain the coordinates of a moving arm. Then, the gesture tracks corresponding to these coordinates are analyzed. Matching and recognition of gesture tracks are implemented by performing golden section search. The results show that this track-based method is highly effective in gesture recognition.

Abstract:
A two-dimensional computer simulation model is developed for dynamic analysis of high-mobility tracked vehicles fitted with a trailing arm suspension system. The simulation model is oriented as a design tool for detailed analysis of vehicle suspension dynamics and ride quality assessment. The Lagrangian model formulation of a tracked vehicle is derived by considering a rigid terrain of an arbitrary profile and constant forward vehicle speed. The model incorporates detailed representations of a vehicle suspension system and dynamic wheel-track-terrain interactions. The wheel forces are evaluated based on an adaptive footprint formulation of a wheel/track-terrain contact patch, and the track forces are modelled based on kinematic considerations. The computer model predictions are validated against field measurements, which were gathered from an extensive field testing of an in-service armoured personnel carrier. The comparison between measured and simulated dynamic responses exhibits a fairly close correlation.

Abstract:
This study innovatively proposes a synchronized gauge-overheight dual-parameter measurement method based on ARM architecture, aiming at solving the problems of low efficiency, high cost, and insufficient accuracy in traditional railroad track inspection. The method realizes efficient and accurate measurement of track geometric parameters by integrating a high-precision magnetotropic displacement sensor and LCF-100 inclinometer sensor. The system adopts a modularized design, uses an ARM processor as the core, and combines Bluetooth wireless transmission technology to construct a low-cost and high-reliability track inspection system. The application of the Bluetooth module not only simplifies the system wiring but also significantly improves the data transmission rate, which makes real-time uploading and processing of measurement data possible and further improves the system's response speed and work efficiency. In the experimental validation phase, the research team verified the measurement accuracy and stability of the method through multiple sets of comparison experiments. The experimental data show that the repeatability accuracy of the data measurement meets the experimental standards. In addition, the system has good environmental adaptability and anti-interference ability and can operate stably under complex working conditions. Through the in-depth analysis and processing of the experimental data by MATLAB software, the research team further optimized the algorithm, reduced the measurement error, and improved the system's overall performance. Compared with traditional track detection methods, this technology has significant advantages. The research results have important theoretical significance and practical application value in the field of railroad safety monitoring, laying a solid foundation for the development of a real-time track condition monitoring system, and also providing a valuable reference for precision measurement in other engineering fields.

Abstract:
Flexible hydraulic robotic arm is a complicated system which coupled by mechanics and hydraulics. It is widely applied in all kinds of large engineering equipments, such as concrete pump truck, bridge monitor truck, arm frame of crane, etc. The arm system of the hydraulic robotic arm is a multi-body system with redundant freedom, strong nonlinear, coupled with rigid and flexible characters. So it is of great theoretic value and real engineering significance to study the arm system of the robotic arm. In this theme, the movement of flexible hydraulic robotic arm and hydraulic cylinders are seperately analyzed with flexible multi-body dynamics, and the mechanical hydraulic dynamic model of the driving system and the arm system is built with Lagrange Equation and Virtual Work Theory. And the dynamic differential equation is built with the driving force of the hydraulic cylinder as the main force. With the track programming and the optimization method, the dynamic converse problem of the arm end track is researched, so as to get the optimized rotation angle when the arm end reaches the expected point. By using the PD control theory, without decoupling and rank-decreasing, only with feed back from the hydraulic system to realize the close loop control of the arm end position, pose and movement, the relationship between the hydraulic system and the end position & pose is studied, so that the flexible distortion is reduced and the libration is restrained. What’s more, the simulation model of the mechanical arms is built by the dynamic simulation software. The simulation result prove that the movement equation built by this way can clearly describe each dynamic character of the mechanical arms.

Abstract:
1. We examined the activity of neurons in the globus pallidus (GP) while monkeys (n = 2) performed sequential pointing movements under two task conditions: visually guided (TRACK task) and remembered (REM task). 2. Almost two-thirds of the task-related neurons in GP (155/236) were considered task dependent because they displayed exclusive or enhanced (greater than +/- 50%) changes in activity for one of the two task conditions. 3. More than 65% of the task-dependent neurons were termed REM neurons because they either displayed changes in activity that occurred only during the REM task or displayed changes that were more pronounced (greater than +/- 50%) during the REM task than during the TRACK task. 4. Nearly half of the REM neurons in GP displayed changes in activity that were limited to a single phase of the REM task (i.e., phase specific). Phase-specific neurons varied in the extent to which their activity depended on the particular sequence of movements performed. Some displayed a change in activity for all of the eight different movement sequences. Others displayed a change in activity during only one of the eight different sequences (i.e., phase and sequence specific). 5. We speculate that an ensemble of GP neurons with phase-specific responses could be used to encode the detailed spatio-temporal characteristics of a sequential movement. In this way, GP neurons would provide part of the neural substrate that solves the "serial order of motor behavior problem".

On both natural and manmade terrains, the maneuverability of mobile robots has been improving. Nevertheless, stair climbing remains a challenging functionality for mobile robots. In this paper, a step-by-step stair climbing approach is proposed for a track-driven mobile robot equipped with flipper arms. The flipper arms are actuated by DC motors controlled by PID controller. Potentiometers and rotary encoders are used to provide closed loop feedbacks. Executable codes are generated using Real-Time Workshop of MATLAB/Simulink. The reference angles to be followed by the flipper arm in stair climbing are emulated and verified by real time experiments.

Abstract:
The development in additive manufacturing methods has cleared the path for topology optimizationby making it possible to produce complex geometries, which would not be possible to produce bytraditional manufacturing methods. Topology optimization uses iterative structural computations tond an optimal material distribution given a maximum optimization domain, load cases and/or otherstructural criteria. The relation between retained mass and structural performance of a swing armfor the vehicle BvS10 was examined for two different materials. The first material was an estimate of an additive manufactured material and the other for a high structural steel. Given the extreme load cases, the geometrical limits of the swing arm and by specifying how much mass was to be retained the stiffness was to be maximized. The optimization was performed using an elastic material model in thecommercial software ANSYS. This elastic material models was based on standard material parameters of steel. Three geometries were generated, namely OG100, OG90 and OG80, which corresponded to 101 %, 87 % and 81 % of the mass of the original swing arm, respectively. The optimization procedurewas combined with geometry modications in SpaceClaim to simplify the obtained geometries. All these geometries consisted of a hollow geometry with a greater width compared to the original geometry. The geometries were then evaluated using multilinear plastic material models based on respective material. Using the additive manufactured material model no generated geometry could perform structurally better than the original swing arm. This indicates that greater material properties must be obtainedin order to be able to reduce the weight of the swing arm. By using the material properties of the highstructural steel, it was found that at least 31.3 kg per vehicle could be reduced by using the optimizedgeometry OG80, and still not perform structurally worse than of the original swing arm.<br>Utvecklingen inom additiv tillverkning har öppnat vägen för topologioptimering genom att kunna producera komplexa geometrier, som inte skulle vara möjliga att tillverka med hjälp av traditionella tillverkningsmetoder. Topologioptimering använder iterativa hållfasthetsberäkningar för att finna den optimala materialfördelning givet en maximal optimeringsdomän, lastfall och/eller andra strukturella kriterier. Relationen mellan bibehållen massa och strukturella prestationer hos en pendelarm till fordonet BvS10 har undersökts för två olika material. Det ena materialet var en uppskattning av ett additivt tillverkat material och det andra materialet var ett höghållfasthetsstål. Givet dem extrema lastfall, geometriska begränsningar hos pendelarmen och genom specficera hur mycket massa som skulle behållas så skulle styvheten maximeras. Optimeringarna utfördes med en elastisk materialmodell i den kommersiellamjukvaran ANSYS. Denna elastiska materialmodell var baserad på klassiska materialparametrarfor stål. Tre geometrier genererades. Optimeringsproceduren användes i kombination med geometriska modikationer i SpaceClaim för att förenkla de optimierade geometrierna. Dessa var OG100, OG90 och OG80, vilka motsvarade 101 %, 87 % och 81 % av pendelarmens originalvikt. Alla geometrier bestod av en ihålig geometri med större bredd än originalarmens. Geometrierna utvärderades sedan med hjälp av multilinjära plastiska materialmodeller baserat på respektive material. Ingen av dessa geometrier kunde prestera bättre än originalarmen när det additivt tillverkade materialet användes. Detta indikerar att bättre materialegenskaper måste uppnås för att kunna reducera vikten hos pendelarmen. Genom attanvända höghållfasthetsstålet upptäcktes att åtminstone 31.3 kg per fordon kunde reduceras genom attanvända OG80, och fortfarande inte prestera sämre än originalarmen.

Abstract:
This study includes an experimental evaluation of a prototype trailing-arm suspension for heavy trucks. The primary goal of this new suspension is to match or improve the kinematics and dynamic performance of an existing â Z-barâ suspension. Significant reductions in cost, weight, and number of parts are the main reasons for this redesign. A permanent facility is constructed to support the testing of different heavy truck suspensions. For actuation of the vehicle suspension, hydraulic actuators are used in the kinematics tests in a quasi-dynamic manner. For the dynamic tests, the vehicle is excited using two hydrodynamic actuators. A collection of forces, displacements, velocities, and accelerations are measured during the tests using transducers that were installed on the suspension and test vehicle. The test measurements are analyzed in both time and frequency domains and then the results of the two suspensions were compared to establish the dynamic merits of the prototype suspension. The kinematics tests include vertical stiffness, roll stiffness, and roll steer measurements for each suspension. The results from the kinematics tests show that the trailing-arm suspension exhibits kinematics traits that are quite similar to the â Z-barâ suspension, within the context of the tests conducted in the study. The dynamic testing consists of three input signals commonly used for such tests, namely: a chirp signal input, a step signal input, and a range of pure tone inputs. The test results show that the resonant frequencies of the two primary suspensions differ by an amount that is most likely too small to affect ride dynamics. The two suspensions, however, exhibit significantly different damping characteristics. The new suspension has much less frictional damping than the existing suspension. This is expected to provide better ride characteristics, assuming that the primary dampers (shock absorbers) are properly tuned for the vehicle that the new suspension was designed for.<br>Master of Science

Abstract:
The purpose of this study was to analyze and determine the predictive power of individual and a combination of different indicators that are used to determine college readiness. For this study a logistic regression analysis was conducted due to the dichotomous nature of the dependent variable. The dependent variable for the study was the earning of a post-secondary credential. The independent variables included high school diploma type, Advanced Placement course taken, Advanced Placement test performance, SAT performance, ACT performance, a multidimensional index made up of all the variables, and high school GPA. The study found that high school GPA had the strongest odds ratio, Exp(B), for the participants earning a post-secondary credential (Exp(B) = 6.597), followed by diploma type (Exp(B) = 6.316), taking an Advanced Placement course (Exp(B) = 4.368), earning at least one qualifying Advanced Placement test score (Exp(B) = 3.846), a multidimensional index (Exp(B) = 2.318), ACT score (Exp(B) = 1.161) and SAT score (Exp(B) = 1.003). Future analysis is needed by using live data of student's college performance, stratifying the data to account for differences in post-secondary performance by different racial and socio-economic groups, and studying the effects of the State of Texas' chosen college readiness variables.

Abstract:
The vocal tract shape is crucial to voice production. Its lower part seems particularly relevant for voice timbre. This study analyzes the detailed morphology of parts of the epilaryngeal tube and the hypopharynx for the sustained German vowels /a/, /e/, /i/, /o/, and /u/ by thirteen male singer subjects who were at the beginning of their academic singing studies. Analysis was based on two different phonatory conditions: a natural, speech-like phonation and a singing phonation, like in classical singing. 3D models of the vocal tract were derived from magnetic resonance imaging and compared with long-term average spectrum analysis of audio recordings from the same subjects. Comparison of singing to the speech-like phonation, which served as reference, showed significant adjustments of the lower vocal tract: an average lowering of the larynx by 8 mm and an increase of the hypopharyngeal cross-sectional area (+ 21.9%) and volume (+ 16.8%). Changes in the analyzed epilaryngeal portion of the vocal tract were not significant. Consequently, lower larynx-to-hypopharynx area and volume ratios were found in singing compared to the speech-like phonation. All evaluated measures of the lower vocal tract varied significantly with vowel quality. Acoustically, an increase of high frequency energy in singing correlated with a wider hypopharyngeal area. The findings offer an explanation how classical male singers might succeed in producing a voice timbre with increased high frequency energy, creating a singer‘s formant cluster.

Abstract:
Aim. The take-off is regarded as the most important phase of the pole vault yet there is an insufficient amount of research on the ground reaction forces of the pole vault takeoff. At this time there is not any scientific research comparing force and time between takeoffs that are out, on and under. The purpose of this study is to compare the differences in ground reaction forces between pole vault take-offs that are out, on or under. Methods. Over five days, 15 male and female college pole vaulters completed 226 vaults on a (AMTI Accupower) force plate. The jumps were put into categories of out, on and under and analyzed by Accupower, and Dartfish software. Separate mixed modal ANOVAs (SAS 9.3) were applied (P?.05) for comparison between jump types. Conclusions. There is no significant difference between ground reaction forces of the three jump types.

Full text
Abstract:
Arc is an IEG expressed in the CA1 sub-field of the hippocampus, following stimulus from an external environment and is expressed in the place cells involved in spatial learning. An initial experiment showed that Arc expression levels decreased with 25 minute rest periods between sessions. The current study aimed to see if similar results are seen with track running, if the rest periods are removed. The rats ran on a small circular track, ensuring that a small ensemble of place cells activate on each lap. Animals were assigned to 4 groups: positive control for Arc induced by MECS; negative control for animals sacrificed from their home cage; a 5 minute group and a 45 minute group. The brain tissue was stained using FISH. The 45 minute group had a 4% lower Arc expression than the 5 minute group. A univariate ANOVA indicated a statistically significant effect in the main factor of Behavioral Group (F= 6.955, p=0.03). Tukey tests showed that the differences between the MECS and the CC groups (p<0.05) and the MECS and the 45 minute groups (p<0.05) were significant. The behavioral groups showed no statistical significance meaning that massed exposure without rest does not attenuate Arc signal.

Abstract:
Abstract According to the current situation of China's agricultural picking, large scale, complex terrain and labor shortage. This design is an all-terrain intelligent agricultural picking robot. The picking robot has the functions of walking, avoiding obstacles and picking. In this paper, the design of robot structure and hardware circuit control is carried out. The basic structure of the design is divided into upper box and lower box. The upper box is a replaceable functional device and the default is a cargo hold and picking robot arm. The lower box is composed of a new all-terrain track motion mechanism and camera module, obstacle avoidance module, power module, transmission module and core control module. The upper box is fixed by a detachable bolt group on the balance table of the lower box, and the mechanical arm is installed in the cargo hold through bolt connection. The end of the mechanical arm is loaded with a pressure sensor, and the new all-terrain track motion mechanism and the drive and sensing control system equipped with the lower box can realize the picking and handling of the operation object. Aiming at the climbing stability, the dynamic modeling was carried out and the maximum climbing height of the robot was obtained based on theoretical calculation and simulation. Through the finite element analysis of the main parts of this design, it is found that the strength meets the requirements of material properties and the calculation is reasonable and reliable. The design has the advantages of stable structure, easy implementation and operation, low cost, strong expansibility and practicability, and easy promotion and application. It can be used with harvesting machinery, spraying equipment, etc., and can also be put into rescue and disaster relief, scientific research and exploration, logistics and transportation and other fields.

Abstract:
AbstractDeep learning architecture has become a cutting-edge method for automatic music generation, but there are still problems such as loss of music style and music structure. This paper presents an improved network structure of time series model based on multi-track music. A context generator is added to the traditional architecture. The context generator is responsible for generating cross-track contextual music features between tracks. The purpose is to better generate single-track and multi-track music features and tunes in time and space. A modified mapping model was further added to further modify the prediction results. Experiments show that compared with traditional methods, the proposed will partially improve the objective music evaluation index results.

Abstract:
AbstractThere is no systematic theory of track finding yet. Therefore, the first section of this chapter presents a list of basic techniques which have been successfully used, stand-alone or in combination, in past and present experiments. Among them are the conformal transformation, the Hough and the Legendre transform, cellular automata and neural networks, pattern matching, and track following by the combinatorial Kalman filter. The following section gives a brief excursion into online or real-time track finding in the collider experiments CDF, ATLAS, and CMS. As track finding in most cases delivers some candidates that do not correspond to actual particle tracks, the concluding section discusses methods for an efficient selection of valid candidates.

Abstract:
AbstractThe methods used for vertex fitting are closely related to the ones used in track fitting. The chapter describes least-squares estimators as well as robust and adaptive estimators. Furthermore, it is shown how the vertex fit can be extended to a kinematic fit by imposing additional constraints on the tracks participating in the fit.

Full text
Abstract:
Abstract Diode laser cladding (DLC) surfaces, valued in the nuclear industry for their wear resistance, corrosion protection, and oxidation resistance, present unique challenges in surface characterization compared to conventionally machined surfaces. While traditional machined surfaces exhibit predictable, periodic topographies that can be validated through simple linear profile measurements, DLC surfaces feature distinctive metal tracks with central peaks and inter-track troughs, creating a wave-like structure with randomly distributed spherical asperities. This complex topography cannot be adequately characterized by traditional single-trace sampling methods due to significant variations in localized features at peaks and troughs. To address this challenge, this study examines DLC surfaces produced under varying control parameters (laser power, head travel speed, powder feed rate, and track offset) using laser confocal microscopy. Both profile and areal surface measurements are compared to identify the most effective method for characterizing DLC surface structure and quality, providing a foundation for standardized quality assessment in industrial applications.

Abstract:
The main goal of this work is to present the SpinLoop Rotational Accelerator project as a preliminary module for accelerating space rockets destined for low Earth orbit. By uti-lizing magnetic levitation technology, which is also used in modern high-speed rail sys-tems (including the thriving Hyperloop technology), it will be possible to design a device that imparts high velocity to the rocket immediately upon launch. This would reduce the amount of fuel the spacecraft would need, thereby decreasing its dimensions and con-struction costs. During the acceleration phase, the rocket would be positioned on a special platform that moves along a magnetic track. This platform would be responsible for bear-ing the load resulting from the rocket�s mass and the centrifugal forces generated during acceleration. The platform itself would be attached to an arm mounted on a shaft, which would receive torque from the propulsion system equipped with an appropriately selected gearbox and an electric motor. The entire setup would be placed within a vacuum cham-ber tilted relative to the horizontal plane, minimizing air resistance and significantly re-ducing power requirements. Once the desired rotational speed is achieved (and the result-ing linear velocity), the platform would detach from the arm and transition from the cir-cular track to a straight track. After stabilizing the trajectory, the rocket would separate from the platform upon exiting the tube, utilizing the imparted velocity to pass through the thickest atmospheric layers. Finally, in the later stages of the flight, rocket engines would be activated to place the vehicle into the desired orbit. This project holds great promise for reducing the costs of launching payloads into near-space and could revolu-tionize space transportation.

Abstract:
The Arm cobot is a three degree-of-freedom manipulator intended for direct physical interaction with a human operator. The Arm cobot can operate as a passive device, such that the cobot sets the end-effector’s allowed direction of motion, while the human operator provides all motive forces. Previous work with the passive Arm cobot involved displaying free motion and virtual paths and surfaces. This paper presents experimental results with a powered Arm cobot. In one experiment, the Arm cobot is commanded to track a user-defined trajectory, while in another experiment, we show an improved free motion controller.

Full text
Abstract:
Hilly terrain poses challenges to truck platoons using fixed set speed cruise control. Driving the front truck efficiently on hilly terrain improves both trucks fuel economies and improves gap maintenance between the trucks. An experimentally-validated simulation model was used to show fuel savings for the platoon of 12.3% when the front truck uses long horizon predictive cruise control (LH-PCC), 8.7% when the front truck uses flexible set speed cruise control, and only 1.2% when the front truck uses fixed set speed cruise control. Purdue, Peloton, and Cummins have jointly configured two Peterbilt 579 trucks for relevant combinations of: (1) coordinated shifting, (2) constant or variable platoon gap controls, (3) flexible or constant speed setpoint cruise control of the front trucks, and (4) long-horizon predictive cruise control (LHPCC) of the front truck. Confirmation of this functionality during platooning was demonstrated at the Continental Test track in Uvalde, Texas. In Indiana, on-road experiments were limited to single truck operation with long-horizon predictive cruise control, flexible set speed cruise control, and constant setpoint cruise control. Data from all of the above was used to improve the fidelity of simulations used to arrive at the fuel savings and gap control findings for hilly terrain per what is summarized in the findings section. Additionally, in early summer 2020, Purdue submitted to, and received improvement from, INDOT for a safe truck platoon testing protocol (located in this report’s appendix), which could not be implemented in Indiana before the end of the project because of COVID-19. Presentations of the subject matter at COMVEC, MAASTO, Purdue Road School, and the Work Truck Show are listed in the appendix.
