Experiences With The Use of Aqueous Cleaning in The Electronics Industry

  • Munie G.

Aqueous processing has been shown to be a viable cleaning method for use in the post-solder cleaning of wave soldered printed wiring assemblies. This paper presents a discussion of aqueous process as it applies to the soldering of surface mount (SM) assemblies. A brief discussion of environmental problems and potential ...

The Karmarkar Algorithm for Communication Facility Capacity Planning

  • Fang S.
  • Slutsman L.

For a given planning horizon, a network loading problem is to find a route and a capacity plan that satisfies customer's demands at each year and the total operation cost. Due to the complexity of the problem, we need a fast algorithm and an efficient implementation. In this paper we ...

Reliability Considerations for Fiber Optic Connections

  • Mettler S.

The term reliability, as applied to optical fiber splices and connectors, usually means the long term stability of the optical connection over long time periods under varying environmental conditions. Reliability requirements for splices and connectors range from stringent (long term dependability under severe conditions), to lenient (temporary connections in air ...

New Directions in the Epitaxial Growth of Insulators and Metals on Silicon by Molecular Beam Epitaxy

  • Phillips J.

There is increasing interest in the growth and characterization of heteroepitaxial structures involving not only semiconductors but also metals and insulators. Various properties of the interfaces of such heterostructures are of crucial importance both for successful epitaxial growth and for applications. A number of recent developments promise to shed light ...

Nonequilibrium Phonon Dynamics in a Semiconductor Quantum Well

  • Cai W.
  • Lax M.
  • Marchetti M.

The dynamics of nonequilibrium phonons in heterolayers, where the carriers are quasi-two-dimensional (2D) while the equilibrium lattice excitations are those of the bulk (3D), require a new theoretical approach. We have derived a kinetic equation for the phonon one-body density matrix, and then transform it to a tractable set of ...

Optical Digital Computers - Devices and Architectures

  • Huang A.

Advances in computation are being limited by communication considerations. The fastest transistors switch in 5 picoseconds whereas the fastest computer runs with a 5 nanosecond clock. This three orders of magnitude disparity in speed can be traced to communication constraints such as connectivity and bandwidth.

Films of High-T sub c Superconductors

  • Hebard A.

Techniques for the fabrication and characterization of thin- film high-T sub c superconductors will be reviewed. This will include a discussion of the technique of reactive ion beam sputter deposition presently being pursued by this speaker. The technical challenges which remain will be related to more general questions concerning the ...

Implementations of Neural Network Models in Silicon

  • Graf H.
  • Mackie S.
  • Schwartz D.

The tasks of speech recognition, stereo vision, optical character recognition, video compression by vector quantization and many others are characterized by a desire to find the best match to an input data string in a large library of previously stored reference strings. In real applications the list may be of ...

Information Dynamics in Design

  • Fritsch C.

Today's market demands are for a wide variety of products, short life cycles, and latest technologies. These factors require various product descriptions and a radically different approach to design and product realization.

A Dual-Based Algorithm for Multiproduct Uncapacitated Facility Location

  • Klincewicz J.
  • Luss H.

The multiproduct uncapacitated facility location problem (MUFLP) is a generalization of the classic uncapacitated facility problem (UFLP). In MUFLP, different products are required by the customers. In addition to the fixed cost for opening a facility, there is an added fixed cost for handling a particular product. Assignment costs are ...

Organic Materials for Nonlinear Optics

  • Katz H.

We present results of studies of oriental order of Langmuir- Boldgett monolayer and multilayer films based on second harmonic generation and linear absorption measurements. New compounds with large second order molecular susceptibilities have been synthesized and transferred as monolayers from the air-water interface to solid supports using the Langmuir-Boldgett technique. ...

Pictures of Karmarkar's Linear Programming Algorithm

  • Gay D.

Karmarkar's linear programming algorithm handles inequality constraints by changing variables to make all constraints about equally distant; it moves in the steepest-descent direction seen by the new variables. This paper summarizes four variants of Karmarkar's linear programming algorithm (primal affine, primal projective, dual affine, and dual projective), discusses depicting polytopes ...

Interval Least Squares - a Diagnostic Tool

  • Gay D.

Linear least-squares models are often used to describe data and make predictions. In using such models, it is important to consider how much uncertainty there may be in the predictions.

Disordering at Ge(111) Surface Near the Bulk Melting Temperature

  • Mcrae E.

The Ge(111) surface undergoes a reversible disordering transition at 1050K, which is 160K below the Ge bulk melting temperature. Low energy electron diffraction (LEED) evidence has been interpreted to support a two-stage disordering mechanism: proliferation of strained double-layer islands with increasing crystal temperatures up to 960K; dissolution of islands at ...
