Abstract:
John Couch Adams predicted the location of Neptune in the sky, calculated the expectation of the change in the mean motion of the Moon due to the Earth’s pull, and determined the origin and the orbit of the Leonids meteor shower which had puzzled astronomers for almost a thousand years. With his achievements Adams can be compared with his good friend George Stokes. Not only were they born in the same year but were also both senior wranglers, received the Smith’s Prizes and Copley medals, lived, thought and researched at Pembroke College, and shared an appreciation of Newton. On the other hand, Adams’ prediction of Neptune’s location had absolutely no influence on its discovery in Berlin. His lunar theory did not offer a physical explanation for the Moon’s motion. The origin of the Leonids was explained by others before him. Adams refused a knighthood and an appointment as Astronomer Royal. He was reluctant and slow to publish, but loved to derive the values of logarithms to 263 decimal places. The maths and calculations at which he so excelled mark one of the high points of celestial mechanics, but are rarely taught nowadays in undergraduate courses. The differences and similarities between Adams and Stokes could not be more striking. This volume attests to the lasting legacy of Stokes’ scientific work. What is then Adams’ legacy? In this contribution, I will outline Adams’ life, instances when Stokes’ and Adams’ lives touched the most, his scientific achievements and a usually overlooked legacy: female higher education and support of a woman astronomer. This article is part of the theme issue ‘Stokes at 200 (part 2)’.

Abstract:
This paper examines the performance of the 3rd and 4th order implicit Adams methods in the framework of the two-loop implicit sparse matrix numerical integration method in solving the differential/algebraic equations of heavily constrained dynamical systems. The variable-step size two-loop implicit sparse matrix numerical integration/Adams method proposed in this investigation avoids numerical force differentiation, ensures satisfying the nonlinear algebraic constraint equations at the position, velocity, and acceleration levels, and allows using sparse matrix techniques for efficiently solving the dynamical equations. The iterative outer loop of the two-loop implicit sparse matrix numerical integration/Adams method is aimed at achieving the convergence of the implicit integration formulae used to solve the independent differential equations of motion, while the inner loop is used to ensure the convergence of the iterative procedure used to satisfy the algebraic constraint equations. To solve the independent differential equations, two different implicit Adams integration formulae are examined in this investigation; a 3rd order implicit Adams-Moulton formula with a 2nd order explicit predictor Adams Bashforth formula, and a 4th order implicit Adams-Moulton formula with a 3rd order explicit predictor Adams Bashforth formula. A standard Newton–Raphson algorithm is used to satisfy the nonlinear algebraic constraint equations at the position level. The constraint equations at the velocity and acceleration levels are linear, and therefore, there is no need for an iterative procedure to solve for the dependent velocities and accelerations. The algorithm used for the error check and step-size change is described. The performance of the two-loop implicit sparse matrix numerical integration/Adams algorithm developed in this investigation is evaluated by comparison with the explicit predictor-corrector Adams method which has a variable-order and variable-step size. Simple and heavily constrained dynamical systems are used to evaluate the accuracy, robustness, damping characteristics, and effect of the outer-loop iterations of the proposed implicit schemes. The results obtained in this investigation show that the two-loop implicit sparse matrix numerical integration methods proposed in this study can be more efficient for stiff systems because of their ability to damp out high-frequency oscillations. Explicit integration methods, on the other hand, can be more efficient in the case of non-stiff systems.

These In order to overcome the behindhand and inefficient design of potato diggers, feature-based parametric modeling software Autodesk Inventor was used for the modeling of potato diggers. The swing sieve, movement simulation with ADAMS was carried out. The complex velocity acceleration and displacement curves were analyzed. Collision pressure curves were analyzed too. νis less than or equal to 500 mm/s, and αis more than or equal to 2.5m/s2, and less than or equal to 20m/s2. Test results indicated that Collision pressures of small and medium tubers are 120 Newton and 250 Newton respectively, which are all smaller than damaging pressure. Potato can be transferred freely and damage rate is less than or equal to 4% when the frequency is 5.5Hz and the swing is 30mm. It satisfies the design request.

Abstract:
SUMMARYIn this study, the kinematics and dynamics of a six-degree-of-freedom parallel manipulator, known as Hexarot, are evaluated. Hexarot is classified under axis-symmetric robotic mechanisms. The manipulator comprises a cylindrical base column and six actuated upper arms, which are connected to a platform through passive joints and six lower arms. The actuators of the mechanism are located inside a cylindrical-shaped base, which allows the mechanism to rotate infinitely about the axes of the latter column. In the context of kinematics, the inverse-kinematic problem is solved using positions, velocities, and accelerations of the actuated joints with respect to the position, orientation, and motion of the platform. Accordingly, the main objective of this study is to dynamically model the manipulator using the Newton–Euler approach. For validation, the obtained dynamic model of the Hexarot manipulator is simulated in MATLAB based on the formulations presented in this paper. The kinematic and dynamic models of the manipulator are simulated for a given motion scenario using MATLAB and ADAMS. The results of the mathematical model obtained using MATLAB are in good agreement with that using the ADAMS model, confirming the effectiveness of the proposed mathematical model.

Abstract:
A 2-DOF manipulator is modeled in PROE. In MATLAB, inverse kinematics is solved by geometric method. The desired trajectory, angular velocity and angular acceleration of each joint are obtained by the linear interpolation of parabola transition to complete the kinematics planning of the manipulator. The velocity of the end-point and the kinematics analysis are got by Newton-Euler method. In PROE, the expected trajectory of the end point is got by the simulation of the position planning. Kinematics simulation on the model is made in ADAMS. The simulation results are consistent with theoretical calculations to verify the correctness of the theory computing, which can provide an effective basis for the control of the manipulator.

Abstract:
Selection of drive components and determination of dynamics properties are extremely important technical components for overall design of palletizing robot. As an example, the paper firstly introduce how to establish mathematical model and finish kinematics analysis. Based on the previous work, MATLAB scripts are written through the use of Newton-Euler Method to analyze and calculate dynamic analysis, after which the parameters of dynamics are obtained. Then the dynamic behavior is studied by multi-body system simulation using ADAMS software to testify the former analysis in MATLAB. Lastly, two speed trajectory algorithm were adopted to simulate for the same working condition, in an attempt to investigate the difference in their dynamic behavior and provide a reliable theoretical basis for optimal control method.

Abstract:
This thesis examines the work of the American Zulu Mission in Natal from 1835 to 1910. Of the institutions controlled by this mission, the most famous was that known in the 20th Century as Adams College, named after one of the founders of the Natal work, Dr Newton Adams. Although other research work has been done on this institution and this mission in general, this thesis attempts to examine the work in the light of the mission's own view of its educational purpose and the expectations of the Colonial Government of what could be expected of missionary education. To meet this purpose particular stress was laid first on the actual development of the mission's educational institutions, especially when reports and letters assessed the aims of the developments and the ways in which these aims were being met. Secondly, the aims of missionary education were explained through five capital Colonial Government Commissions, which looked, in a number of different ways, at the current position and future of the Zulu peoples of Natal. These Commissions reported in 1846, 1852-1853, 1881-1882, 1892 and 1902. Two major findings emerge from the investigation. The first was lack of clarity, not only on the part of what the mission was trying to do, but also on what the Colonial Government expected it to do. To this absence of clarity must be added the continuous shortage of finance, the reluctance of the Zulu themselves to accept the combination of education (which they wanted) and conversion (of which they were often suspicious). In these circumstances, their slow progress of the 75 years from 1835 to 1910 becomes understandable. Had these years been the total extent of the mission' s contribution to Natal, there would be little justification for any extended investigation, or any reason behind the high prestige which the mission enjoyed. It is shown, however, that from 1902 onwards a new, more incisive and directional policy, especially on the question of education, came from the mission. This emerged particularly under the leadership of Le Roy, Principal from 1903 to 1925. The last part of this thesis assesses this new direction. The detailed investigation comes to an end at 1910 when with the creation of Union, an entirely new organisation and dispensation came into being. In the last years of Le Roy's principalship the promise of the period of 1902 to 1920 came to fruition and in the final chapter a brief summary of these developments are given

Abstract:
This book treats Adam Smith as a systematic philosopher. Smith was a giant of the Scottish Enlightenment with polymath interests. The book explores Smith’s economics and ethics in light of his other commitments on the nature of knowledge, the theory of emotions, the theory of mind, his account of language, the nature of causation, and his views on methodology. It places Smith’s ideas in the context of a host of other philosophers, especially David Hume, Rousseau, and Isaac Newton; it draws on the reception of Smith’s ideas by Sophie de Grouchy, Mary Wollstonecraft, and other philosophers and economists to sketch the elements of and the detailed connections within Smith’s system. The book traces out Smith’s system and puts it in the context of his highly developed views on the norms that govern responsible speech. In particular, the book articulates Smith’s concerns with the impact of his public policy recommendations, especially on the least powerful in society. In so doing, the book offers new interpretations of Smith’s views on the invisible hand, Wealth of Nations, his treatment of virtue, the nature of freedom, the individual’s relationship to society, his account of the passions, the moral roles of religion, and his treatment of the role of mathematics in economics. While the book offers a single argument, it is organized in modular fashion and includes a helpful index; readers with a more focused interest in Smith’s achievements can skip ahead to the section of interest.

Abstract:
This chapter argues that in general Adam Smith is distinctly reserved about the application of mathematics to political economy and even other terrestrial sciences. Smith endorses a so-called containment strategy—that is, he restricts the application of mathematics to a fairly limited domain of enquiry. Smith was not alone in such a containment strategy: we find instances of it in Locke, Buffon (whom he admired), and Mandeville. Such a containment strategy is part of a wider trend of eighteenth-century “anti-mathematicism,” the expressed reservations about the authority and utility of the application of mathematical sciences. By treating Smith as instantiating such anti-mathematicism, this chapter deviates from the recent tendency of arguing that Smith meant to emulate Isaac Newton.

Abstract:
This chapter offers a new take on the history of science by detailing how the turn from Scholasticism in the seventeenth and eighteenth centuries took the form of a gradual turn to system as the “firmer” form of what the physicist, and Enlightenment scholar, David Deutsch calls “guesswork.” That turn was completed in grand fashion with Newton’s decision to communicate his principles and laws philosophically by adding a “System of the World” to his treatise. I explain how and why Newton came very close—repeatedly—to sending the Principia into the world without any “System” at all. Why was system such a vexed issue in the late seventeenth century? What was at stake for Newton in choosing to write a system over competitors such as “hypothesis”? And why, once it did make it onto the printed page, did system become so successful that a copy of Newton’s system was launched into space as one of humanity’s calling cards three centuries later? How did that particular form of knowledge come to represent—for Condillac, Goldsmith, Hume, Pownall, Granger—our species’ good and bad efforts to advance knowledge? The primary generic marker of what came to be called Enlightenment, I conclude, were the monumental efforts—highlighted by Adam Smith’s project for Scotland—to scale up systems into master SYSTEMs that persisted from roughly the 1730s through the 1780s.

Abstract:
This chapter reviews the incidence, epidemiology, genetics, and anatomical varieties of congenital anomalies of the lower extremity. Defects can be transverse, longitudinal, intercalary, or central and involve the femur, tibia, or fibula and there are combined defects and conditions affecting both upper and lower extremity. Isolated transverse defects are less common in the lower extremity than the upper but amniotic band disruption sequence can affect both upper and lower limbs. Adams Oliver syndrome affects both upper and lower limbs. Femoral facial syndrome is the most common lower extremity syndrome. Split hand/split foot is clinically heterogeneous and complex albeit with several well characterized syndromes including those caused by variants in TP63 and the 17p1.3. chromosome duplicaton syndrome . The clinical case presentation features an infant with fibular aplasia, tibial campomelia, and oligosyndactyly due to FATCO syndrome, a condition whose genetic cause is unknown.

Abstract:
The dynamics of large scale and complex multibody systems (MBS) that include flexible bodies and contact/impact pairs is governed by stiff equations. Because explicit integration methods can be very inefficient and often fail in the case of stiff problems, the use of implicit numerical integration methods is recommended in this case. This paper presents a new and efficient implementation of the two-loop implicit sparse matrix numerical integration (TLISMNI) method proposed for the solution of constrained rigid and flexible MBS differential and algebraic equations. The TLISMNI method has desirable features that include avoiding numerical differentiation of the forces, allowing for an efficient sparse matrix implementation, and ensuring that the kinematic constraint equations are satisfied at the position, velocity and acceleration levels. In this method, a sparse Lagrangian augmented form of the equations of motion that ensures that the constraints are satisfied at the acceleration level is first used to solve for all the accelerations and Lagrange multipliers. The generalized coordinate partitioning or recursive methods can be used to satisfy the constraint equations at the position and velocity levels. In order to improve the efficiency and robustness of the TLISMNI method, the simple iteration and the Jacobian-Free Newton-Krylov approaches are used in this investigation. The new implementation is tested using several low order formulas that include Hilber–Hughes–Taylor (HHT), L-stable Park, A-stable Trapezoidal, and A-stable BDF methods. The HHT method allow for including numerical damping. Discussion on which method is more appropriate to use for a certain application is provided. The paper also discusses TLISMNI implementation issues including the step size selection, the convergence criteria, the error control, and the effect of the numerical damping. The use of the computer algorithm described in this paper is demonstrated by solving complex rigid and flexible tracked vehicle models, railroad vehicle models, and very stiff structure problems. The results, obtained using these low order formulas, are compared with the results obtained using the explicit Adams-Bashforth predictor-corrector method. Using the TLISMNI method, which does not require numerical differentiation of the forces and allows for an efficient sparse matrix implementation, for solving complex and stiff structure problems leads to significant computational cost saving as demonstrated in this paper. In some problems, it was found that the new TLISMNI implementation is 35 times faster than the explicit Adams-Bashforth method.

Full text
Abstract:
This paper describes a planar or two-dimensional model to examine the gross motions of rail cars in a generalized train derailment. Three coupled, second-order differential equations are derived from Newton’s Laws to calculate rigid-body car motions with time. Car motions are defined with respect to a right-handed and fixed (i.e., non-rotating) reference frame. The rail cars are translating and rotating but not deforming. Moreover, the differential equations are considered as stiff, requiring relatively small time steps in the numerical solution, which is carried out using a FORTRAN computer code. Sensitivity studies are conducted using the purpose-built model to examine the relative effect of different factors on the derailment outcome. These factors include the number of cars in the train makeup, car mass, initial translational and rotational velocities, and coefficients of friction. Derailment outcomes include the number of derailed cars, maximum closing velocities (i.e., relative velocities between impacting cars), and peak coupler forces. Results from the purpose-built model are also compared to those from a model for derailment dynamics developed using commercial software for rigid-body dynamics called Automatic Dynamic Analysis of Mechanical Systems (ADAMS). Moreover, the purpose-built and the ADAMS models produce nearly identical results, which suggest that the dynamics are being calculated correctly in both models.
