Bypassing the Chain of Command: The Political Origins of the RCN’s Equipment Crisis of 1943

At the behest of Angus L. Macdonald, the Minister of National Defence for Naval Services, John Joseph Connolly conducted a secret investigation in October 1943 into the state of equipment on Canadian warships. Connolly, who was Macdonald’s executive assistant, traveled to St. John’s, Londonderry and London where he discovered that the Royal Canadian Navy (RCN) was far behind its allies in the modernization of its escort fleet. Canadian ships lacked gyroscopic compasses, hedgehog, effective radar and asdic, as well as other technical gear that was essential in the Battle of the Atlantic. These deficiencies should not have come as a surprise. Inadequate equipment on RCN ships had already become obvious during the intense convoy battles of 1941, and had been confirmed yet again by those of 1942. Insufficient training and manning policies also played their part in Canadian problems at sea. However, it was to be the technical aspects that Macdonald focused upon once Connolly returned from overseas, leading not only to a disruptive feud with the naval staff, but also, in their way, to the eventual replacement of Vice Admiral Percy W. Nelles as the Chief of the Naval Staff (CNS) in January 1944

The Great Naval Battle of North Point: Myth or Reality?

Hollywood itself could hardly have scripted a better battle. According to eyewitnesses, a German U-boat lurking off the shores of North Point, Prince Edward Island, laid a trap for an unsuspecting convoy transitting the Northumberland Strait. On 7 May 1943, the trap was sprung, Canadian naval escorts and aircraft did their best to defend the beleaguered convoy from a brazen and unorthodox attack that was unlike any other. There could only be one conclusion: the German commander was half-mad. Just like the fictional Captain Ahab, he was willing to take unwarranted risks with his boat and men to destroy his white whale that came in the form of a troop ship at the centre of the convoy. His obsession led to a stunning three hour engagement that was brought to a dramatic end as the Canadians scored a direct hit forcing the U-boat’s bow to rise sharply out of the water before sinking. The problem is that there is no evidence that this battle ever took place

On the development of slime mould morphological, intracellular and heterotic computing devices

The use of live biological substrates in the fabrication of unconventional computing (UC) devices is steadily transcending the barriers between science fiction and reality, but efforts in this direction are impeded by ethical considerations, the field’s restrictively broad multidisciplinarity and our incomplete knowledge of fundamental biological processes. As such, very few functional prototypes of biological UC devices have been produced to date. This thesis aims to demonstrate the computational polymorphism and polyfunctionality of a chosen biological substrate — slime mould Physarum polycephalum, an arguably ‘simple’ single-celled organism — and how these properties can be harnessed to create laboratory experimental prototypes of functionally-useful biological UC prototypes. Computing devices utilising live slime mould as their key constituent element can be developed into a) heterotic, or hybrid devices, which are based on electrical recognition of slime mould behaviour via machine-organism interfaces, b) whole-organism-scale morphological processors, whose output is the organism’s morphological adaptation to environmental stimuli (input) and c) intracellular processors wherein data are represented by energetic signalling events mediated by the cytoskeleton, a nano-scale protein network. It is demonstrated that each category of device is capable of implementing logic and furthermore, specific applications for each class may be engineered, such as image processing applications for morphological processors and biosensors in the case of heterotic devices. The results presented are supported by a range of computer modelling experiments using cellular automata and multi-agent modelling. We conclude that P. polycephalum is a polymorphic UC substrate insofar as it can process multimodal sensory input and polyfunctional in its demonstrable ability to undertake a variety of computing problems. Furthermore, our results are highly applicable to the study of other living UC substrates and will inform future work in UC, biosensing, and biomedicine
