Modified Broyden’S Method For Accelerating Convergence In Self-Consistent Calculations, Duane D. Johnson Dec 1988

Modified Broyden’S Method For Accelerating Convergence In Self-Consistent Calculations, Duane D. Johnson

Duane D. Johnson

A modification to Broyden’s method for obtaining stable and computationally efficient convergence in self-consistent calculations is developed and discussed. The method incorporates the advantages of two schemes proposed by Srivastava and by Vanderbilt and Louie without any increase in complexity. Its improvement over their methods is discussed. The present method is compared with two other widely used convergence methods, simple mixing and Anderson’s method, for the case of the disordered binary alloy Ni0.35Fe0.65 on the verge of a magnetic instability and is shown to be much improved in stability and rate of convergence.


Portable Curing Frame, George B. Day V, Larry G. Wells, Timothy D. Smith, Ira J. Ross Dec 1988

Portable Curing Frame, George B. Day V, Larry G. Wells, Timothy D. Smith, Ira J. Ross

Biosystems and Agricultural Engineering Faculty Patents

A portable curing frame is provided particularly adapted for use with an automated tobacco harvester. The curing frame includes a substantially rectangular frame member including a series of slotted tracks, in the form of slotted tubes, specially designed for receiving a notched portion of the plant stalks. The slotted track is substantially continuous and thereby allows infinitely variable spacing between the plants and optimization of ventilation for air curing. Legs are also provided on the portable curing frame. The legs are displaceable between a retracted position allowing storage of the frames and loading of the frames with tobacco plants and ...

Force Distribution In Closed Kinematic Chains, Vijay R. Kumar, Kenneth J. Waldron Dec 1988

Force Distribution In Closed Kinematic Chains, Vijay R. Kumar, Kenneth J. Waldron

Departmental Papers (MEAM)

The problem of force distribution in systems involving multiple frictional contacts between actively coordinated mechanisms and passive objects is examined. The special case in which the contact interaction can he modeled by three components of forces (zero moments) is particularly interesting. The Moore-Penrose Generalized Inverse solution for such a model (point contact) is shown to yield a solution vector such that the difference between the forces at any two contact points projected along the line joining the two points vanishes. Such a system of contact forces is described by a helicoidal vector field which is geometrically similar to the velocity ...

A Systematic Transition To Flexible Manufacturing, Sema E. Alptekin, Daniel L. Webber Dec 1988

A Systematic Transition To Flexible Manufacturing, Sema E. Alptekin, Daniel L. Webber

Industrial and Manufacturing Engineering

The transition from basic automation to flexible manufacturing is an expensive and tedious procedure. It requires meticulous planning and almost clairvoyant forecasting to insure that the initial flexibility obtained is sufficient to allow growth and expansion in the future. This paper will suggest a systematic and methodological approach to achieve optimal flexibility and describe the present results of its application to an ongoing system transformation. Conclusions based on existing levels of completion are presented along with identification of critical and non critical flexibility requirements. The considerations and steps taken are summarized in a procedural format which may then be applied ...


The Role Of The Peripheral Vascular Bed In Arterial Pulse Wave Propagation, L. S. Baker, F. A. Anderson, Jr., H. B. Wheeler, William W. Durgin Dec 1988

The Role Of The Peripheral Vascular Bed In Arterial Pulse Wave Propagation, L. S. Baker, F. A. Anderson, Jr., H. B. Wheeler, William W. Durgin

Office of the Provost and Vice President of Academic Affairs Scholarship

An analytical model was developed to simulate human arterial pulse wave propagation in major arteries. It was verified with an experimental model. The models investigated the effects of the peripheral vascular bed on pressure pulse morphology. The models revealed that the capillary bed in normal humans acts as a high resistance, low reflectance, boundary condition.

Limitation Of Sulfur Dioxide Removal In A Fgd Spray Dryer Using Once Through Slaked Lime, Sambamurty Raju Dantuluri Dec 1988

Limitation Of Sulfur Dioxide Removal In A Fgd Spray Dryer Using Once Through Slaked Lime, Sambamurty Raju Dantuluri

Doctoral Dissertations

The present study discusses the importance of slaking operation and its effect on the removal efficiency in a spray dryer operated FGD system using slaked lime slurry. Laboratory scale slaking experiments were run to look into various characteristics of resulting slurry. Pilot plant tests were made to quantify the effects of different parameters on spray removal efficiency. A vertical tower mill was used to grind calcium hydroxide slurry to attain smaller particle size. X-ray diffraction and SEM techniques were used to visualize the crystallinity and surface aspects of calcium hydroxide slurry. Sorbent particle size and surface area measurements were made ...


On A Taylor Weak Statement For Finite Element Computations In Gas Dynamics, Jin Whan Kim Dec 1988

On A Taylor Weak Statement For Finite Element Computations In Gas Dynamics, Jin Whan Kim

Doctoral Dissertations

The Taylor Weak Statement has been developed as a potential unified approach for approximate computation of fluid flows. It is verified to contain a variety of numerical dissipative methods developed for advection problems by specific identification of its expansion parameters. Generalized Fourier modal analysis has been completed in one space dimension for both semi-and fully-discrete approximations, from which the flux limiter method is herein developed and evaluated for finite element computations. Its application to 1- and 2-dimensional scalar models is investigated for continuous and discontinuous initial value problems, and its use for the Euler equation system of gas dynamics in ...


Energy Considerations In Stock Preparation Refining Modified By Recycling, Rajendra D. Deshpande Dec 1988

Energy Considerations In Stock Preparation Refining Modified By Recycling, Rajendra D. Deshpande

Master's Theses

Experiments were conducted to study the effect of refining on virgin fibers as well as on recycled fibers. Interaction effects of recycling and type of treatment of virgin fibers on characteristics of secondary fiber were studied. A significant reduction in drainage properties of the furnish for both hardwood and softwood pulps were observed. This reduction in properties was found proportional to the amount of refining. It is necessary to achieve required strength properties at higher freeness values, if fibers are to be recycled. This can be done by improvement in uniformity or homogeneity of refining and by gentler and less ...
