Quarterly report discussing fuel cell research and development work at Argonne National Laboratory (ANL). This report describes efforts directed toward understanding and improving the components of molten-carbonate-electrolyte fuel cells operated at temperatures near 925 K.

Evaluation of melt-slagging techniques as a decontamination and consolidation step for metals contaminated with oxides of plutonium and americium.

Two ergodic theorems are presented for means of nonlinear contraction semigroups in a Hilbert space. These means are generated by a class of averaging kernels which includes the usual Abel and Cesaro-(C,cap alpha) kernels.

Report discusses the development of the existing ALICE Image Processing System into a computer-aided digitization, encoding, analysis and display system for mapped information pertaining to the environment and its elements.

Volume 2 presents information which is directly related to the actual computer code arid operational characteristics (keys and subroutines) of the software. The authors expect that Volume I will be of more interest to developers of software than to users of the software. However, developers of software should be aware that the code developed for the ALICE System operates in an environment where much of the peripheral hardware to the PDP-10 is ANL/AMD built. For this reason, portions of the code may have to be modified for implementation on other computer system configurations.

This report is concerned with ergodic theorems for Abel means of nonlinear contraction mappings and nonlinear contraction semigroups in a Hilbert space.

Let E be a reflexive Banach space with a uniformly Gateaux differentiable norm, D a closed convex subset of E, and C a nonexpansive retract of D.
