Journal Article
Grant, P. M., & Rutter, M. (1984). The application of gradient adaptive lattice filters to channel equalisation. IEE proceedings. F, Communications, radar, and signal processing, 131(5), 473-479. https://doi.org/10.1049/ip-f-1%3A19840073

In this paper, the potential application of adaptive lattice equalisers based on gradient search adaptive
algorithms, is examined. The assessment is based on simulations of equaliser performance in data communications
systems which provides a compa... Read More about The application of gradient adaptive lattice filters to channel equalisation.

Axisymmetric outflow from large vessels (1984)
Journal Article
Kubie, J. (1984). Axisymmetric outflow from large vessels. Proceedings of the Institution of Mechanical Engineers. Part A, Power and process engineering, 198(5), 113-119. https://doi.org/10.1243/pime_proc_1984_198_016_02

A model of axisymmetric liquid outflow from large vessels is developed and is used to explain aspects of flow for self-venting and choked outlets. It is shown that for flows with self-venting outlets the model relates the liquid level to the flow. It... Read More about Axisymmetric outflow from large vessels.

An architecture and syntax for distributed databases (1984)

Recently, there has been a lot of work undertaken in the area of distributed databases. The architecture and syntax presented in this paper is a response to the very real need for the development of a unified approach to distributed databases. The de...

Three solutions for a robot arm controller using Pascal-Plus, occam and edison (1984)
Journal Article
Kerridge, J. M., & Simpson, D. (1984). Three solutions for a robot arm controller using Pascal-Plus, occam and edison. Software: Practice and Experience, 14(1), 3-15. https://doi.org/10.1002/spe.4380140103

Three currently available concurrent language systems, Pascal‐Plus, occam and Edison, are used to implement a controller for a robot arm. The robot arm allows real parallelism of operation within the movements of the arm. The feasibility and restrict...

Generation of codes with good autocorrelation properties (1983)
Journal Article
Rutter, M., & Grant, P. M. (1983). Generation of codes with good autocorrelation properties. Electronics Letters, 19, 571-572. https://doi.org/10.1049/el%3A19830389

The letter describes a conceptually simple method of generating
impulse equivalent burst and cyclic codes, using an
all-pass autoregressive moving average (ARMA) filter. These
infinite impulse response burst codes may be converted into
cyclic cod... Read More about Generation of codes with good autocorrelation properties.

Open-loop transversal equaliser of optimal length (1983)
Journal Article
Rutter, M., & Cowan, C. F. N. (1983). Open-loop transversal equaliser of optimal length. Electronics Letters, 19, 208-210. https://doi.org/10.1049/el%3A19830144

As a rule, in equaliser training algorithms complexity
increases with efficiency. Unfortunately, complex recursive
algorithms do not suit high-bandwidth systems. This letter
describes a nonrecursive technique for the derivation of the
weight vect... Read More about Open-loop transversal equaliser of optimal length.

Performance and design of plug‐type check valves (1982)
Journal Article
Kubie, J. (1982). Performance and design of plug‐type check valves. Proceedings / Institution of Mechanical Engineers, 196(1982), 47-56. https://doi.org/10.1243/pime_proc_1982_196_006_02

Plug check valves are frequently used in high pressure systems where parallel pump operations are envisaged, in order to prevent flow recirculation through the out-of-service pump. Serious operational problems are sometimes encountered with these val... Read More about Performance and design of plug‐type check valves.
