5 Boll, Steven F.Improving linear prediction analysis of noisy speech by predictive noise cancellationThe analysis of speech using Linear Prediction is reformulated to account for the presence of acoustically added noise and a technique is presented for reducing its effect on parameter estimation. The method, called Predictive Noise Cancellation (PNC), modifies the noisy speech autocorrelations ...Linear prediction; Predictive Noise Cancellation; Noisy speech; Sppech analysis1977

7 Ailion, David CharlesNew NMR techniques to study diffusion in multispin crystalsWe present a new NMR method for studying slow diffusion in multispin systems. With this method we can vary the effect of a particular spin species' motion relative to the others, thus enabling us to separate and identify the component motions. We present a new pulse sequence for measuring T1L', a ge...NMR; Nuclear magnetic resonance; Crystals; Nuclear-spin species; Diffusion; Molecular rotations1977
8 Ailion, David CharlesNMR in lithium metal: thermal mixingWe present a calculation of the thermal mixing rate t~ 1 between nuclear Zeeman and dipolar reservoirs in the presence of large rf fields. We applied this calculation to slow-motion diffusion in lithium metal. In particular, we measured the rotating frame spin-lattice relaxation time Tl p as a funct...NMR; Nuclear magnetic resonance; Lattices; Relaxation time1977
9 Hartmann, Donald P.Considerations in the choice of interobserver reliability estimatesTwo types of interobserver reliability values may be needed in treatment studies in which observers constitute the primary data-acquisition system: trial reilability and the reliability of the composite unit or score which is subsequently analyzed, e.g., daily or weekly session totals. Two approache...Observational technology; Reliability; Validity; Statistics; Recording and measurement techniques; Cohen's kappa; Generalizability theory; Measurement theory; Spearman-Brown prophesy formula; Correlational measures1977
10 Ailion, David CharlesNuclear magnetic resonance in LiF: a single nuclear-dipolar-spin temperature in crystals with more than one spin speciesIn a crystal containing more than one species of nuclear spin in a large dc magnetic field, the secular dipolar interactions between all spins, unlike as well as like, form a single reservoir described by a single spin temperature. We demonstrated this concept with experiments on LiF. In particula...Spin species; Spin-lattice relaxation; NMR; Nuclear magnetic resonance1977
11 Lindstrom, Gary E.CONSIM: a converstional simulation language implemented through interpretive control self-modelingThis paper describes an implementation technique termed interpretive control self-modeling (ICSM) and outlines its application in the implementation of CONSIM, a prototype conversational simulation language. ICSM may be defined as the use of a higher-level programming language (HLL) to specify its o...CONSIM; Converstional simulation language; Interpretive control self-modeling; ICSM1977
12 Lindstrom, Gary E.Efficiency in nondeterministic control through non-forgetful backtrackingNondeterministic (ND) control has long been used to express elegant solutions to complex search problems. Programs using ND control can be executed on conventional machines through a systematic examination of trial execution paths. Among the many approaches to the enumeration of these paths is backt...Nondeterministic control; Non-forgetful backtracking; Search problems1977
13 Boll, Steven F.Noise suppression methods for robust speech processing (1 Oct. 1976 - 31 March 1977)To develop robust speech processes, based upon the integration of digital noise suppression methods and narrow band speech analysis-synthesis methods, capable of realizing practical, real time methods for effectively processing speech recorded in practical operating environments.Digital noise suppression1977
14 Davis, A.L.The architecture of DDMl: a recursively structured data driven machineAn architecture for a highly modular, recursively structured class of machines is presented. DDMl is an instance of such a machine structure, and is capable of executing machine language programs which are data driven (data flow) nets. These nets may represent arbitrary amounts of concurrency as wel...DDMl; machine structure; machine language programs1977
15 Capecchi, Mario R.Isolation of a suppressible nonsense mutant in mammalian cellsAn HGPRT- cell line derived from mouse L cells has been shown to have the following properties: it is CRM'; the defective HGPRT molecules are altered in the carboxyterminal peptide; the mutant cells regain HGPRT activity when ochre-suppressor tRNA is microinjected into them, but not when amber...HGPRT cell line; HGPRT activity; Ochre nonsense mutation; Mouse L cells; Mammalian cells1977
16 Ailion, David CharlesNuclear double resonance: cross relaxation rates between two spin speciesA rotating-frame nuclear-double-resonance experiment is reported in which the cross-relaxation rates between 7Li and 6Li in powdered lithium metal were measured. The theory developed my McArthur, Hahn, and Walstedt (MHW) is applied to these data and good agreement is obtained. We also apply this t...Nuclear-double-resonance; Lithium; MHW; Cross-relaxation1977
17 Keller, Robert M.Semantics of parallel program graphsA denotational model for networks of parallel processes is presented which generalizes the work of Kahn by using alternative data types, e.g. Lisp-like operators on trees. It is shown that the ordering aspect of data types plays a central role in determining how much parallelism can be present. It i...Parallel program graphs; Computer semantics; Denotational model1977
18 Keller, Robert M.Denotational models for parallel programs with indeterminate operatorsSeveral approaches to networks of concurrently-operating modules involving indeterminacy are discussed. Techniques for representing the denotational semantics of such networks, and for verifying properties of them, are presented, including an oracle approach, an axiomatic approach, a data-type reduc...Denotational models; Indeterminate operators1977
