An energy efficient time-mode digit classification neural network implementation
No full textThis paper presents the design of an ultra-low energy neural network that uses time-mode signal processing). Handwritten digit classification using a single-layer artificial neural network (ANN) with a Softmin-based activation function is described as an implementation example. To realize time-mode operation, the presented design makes use of monostable multivibrator-based multiplying analogue-to-time converters, fixed-width pulse generators and basic digital gates. The time-mode digit classification ANN was designed in a standard CMOS 0.18 μm IC process and operates from a supply voltage of 0.6 V. The system operates on the MNIST database of handwritten digits with quantized neuron weights and has a classification accuracy of 88%, which is typical for single-layer ANNs, while dissipating 65.74 pJ per classification with a speed of 2.37 k classifications per second. This article is part of the theme issue 'Harmonizing energy-autonomous computing and intelligence'.Accepted Author ManuscriptBio-Electronic
Economising mooring and guiding constructions at lock approaches in inland waterways – the Dutch experience
No full textAs a result of diminishing budgets for maintenance, the Dutch waterway authority Rijkswaterstaat is amongst others in search for economizing infrastructural facilities for commercial inland vessels along its waterways. One type of those facilities are the mooring constructions for line up- and waiting areas at lock approaches. Another type are the guiding constructions for entering the lock chamber, the so called funnels. The mooring and guiding constructions basicly exist of piles, connected by crossbeams and can be designed in either a fixed or a floating version, depending on the fall of the waterway.Hydraulic EngineeringCivil Engineering and Geoscience
The role of classification and reference vessels in the design of inland fairways for commercial vessels – contribution to the Workshop of WG 141 Design Guidelines for Inland Waterways
No full textThe Pianc WG 141 is proceeding in the conception of Design Guidelines for Inland Waterways. WG 141 aims to produce its first draft in the end of 2015. Part of the forseen content are classification of waterways and the object of reference vessels. The role of those subjects will be presented and discussed in the Workshop, that WG 141 will give during the Smart Rivers 2015 Conference, scheduled at the 8th of September.Hydraulic EngineeringCivil Engineering and Geoscience

Richtlijnen Vaarwegen 2020
No full textDe Richtlijnen Vaarwegen bundelen de Nederlandse kennis op het gebied van het ontwerp en de inrichting van vaarwegen, zowel vaarwegvakken als havens, bruggen en sluizen. De richtlijnen geven aanwijzingen voor het kiezen van een maatgevend schip en maatgevende hydraulische randvoorwaarden voor zowel beroeps- als recreatievaart. De richtlijnen gelden voor vaarwegen tot en met CEMT-klasse VI. Door vaarwegen volgens dezelfde richtlijnen te ontwerpen, ontstaat een beter samenhangend vaarwegennetwerk
Workshop Design Guidelines for Inland Waterways – Best Practice Approach – using existing examples (PIANC-INCOM WG 141)
No full textThe Pianc Working group 141 is in progress to develop design guidelines for Inland Waterways. In advance of publication of the final report, this paper consists of paragraph 6.2 of the report to come. The possibility exists that the content of this paper needs to be revised to suit with the other (future) subjects in the framework of the final report. The best practice approach can be used if the design case under consideration is not handled in existing guidelines, or if there are doubts about the applicability of their recommendations. This means one is looking for comparable existing design cases. This can be helpful e.g. for fairway design in rivers.Hydraulic EngineeringCivil Engineering and Geoscience
