On the Impact of Optimal Modulation and FEC Overhead on Future Optical Networks
The potential of optimum selection of modulation and forward error correction
(FEC) overhead (OH) in future transparent nonlinear optical mesh networks is
studied from an information theory perspective. Different network topologies
are studied as well as both ideal soft-decision (SD) and hard-decision (HD) FEC
based on demap-and-decode (bit-wise) receivers. When compared to the de-facto
QPSK with 7% OH, our results show large gains in network throughput. When
compared to SD-FEC, HD-FEC is shown to cause network throughput losses of 12%,
15%, and 20% for a country, continental, and global network topology,
respectively. Furthermore, it is shown that most of the theoretically possible
gains can be achieved by using one modulation format and only two OHs. This is
in contrast to the infinite number of OHs required in the ideal case. The
obtained optimal OHs are between 5% and 80%, which highlights the potential
advantage of using FEC with high OHs.Comment: Some minor typos were correcte

Solution to a problem of Nirenberg concerning expanding maps
By constructing a map of a separable Hilbert space into itself that is continuous, expanding, nonsurjective, and equal to the identity on the unit ball we answer a problem stated by Louis Nirenberg
Lake Michigan Salmonid Stocking Costs in Wisconsin
The costs of stocking salmonids in the Wisconsin waters of Lake Michigan are estimated for 1985. Estimation procedures and costs per stocked and captured fish are presented. Fingerlings of a species were found in most cases to cost more per captured fish than yearlings. However chinook salmon fingerlings were least expensive at an average cost of only 12.67 and $10.14 respectively. While a full policy evaluation awaits additional research on species specific benefits, three tentative conclusions can be drawn for the Wisconsin fishery. First, the role of brook trout in the fishery should be reviewed. Second, despite difficulties with lake trout rehabilitation, the role of lake trout in the sport fishery is encouraging and may justify continued stocking. Finally, increased stocking of the popular chinook salmon may be justified if the recent problems of low capture-per-release rates can be solved.restocking costs, benefit-cost methodology, sport fisheries, salmonids, Lake Michigan, Environmental Economics and Policy, Resource /Energy Economics and Policy,

Design Considerations for Low-Margin Elastic Optical Networks in the Nonlinear Regime
We demonstrate from a system design perspective, that nonlinearity can be exploited, to minimize the impact of system margins on the system performance, both for point-to-point links and elastic optical networks. A nonlinear interaction causes a 2 dB reduction in launch power to be reduced to <0.25 dB signal-to-noise ratio (SNR) penalty and likewise, a 2 dB peak-peak (pk-pk) perturbation to the output power of an optical amplifier incurs <0.25 dB SNR penalty (for 5, 10 and 20 spans). Extending this to a gain ripple of 1 dB pk-pk with an internode spacing of 5x80 km, 10x80 km and 20x80 km the penalty is 0.4 dB, 1.5 dB and 5.1 dB, respectively, with pre-emphasis reducing this to 0.01 dB, 0.3 dB and 1.2 dB respectively. In elastic optical networks we consider the nonlinear relationship between SNR, margin and the fraction of capacity available. We consider scaling internode distances of a 9-node German scale network (DT9) such that the initial network diameter increases from 1,120 km to 6,720 km (six-fold scaling). We generate 1,000 different topologies based on the scaled DT9 node locations to quantify the impact of margin. For the unscaled DT9 network a 3 dB margin results in, on average, a 21% reduction in network throughput, however when the internode spacing is increased six-fold to a continental scale network, the network throughput is reduced by 40%, on average, for the same 3 dB margin.RJV acknowledges funding from EPSRC and BT through an

Strategies for Managing Citizen Developers and No-Code Tools
No-code and low-code development tools promise faster development and productivity gains by circumventing the traditional IT bottleneck. These tools pose both opportunities and challenges, especially when used by citizen developers. Based on the no-code experiences of various organizations, we identify the strengths of these tools and the risks, as well as the misalignments between no-code-empowered citizen developers and corporate IT departments. We also provide recommended strategies for managing citizen developers and leveraging no-code tools to enhance organizational agility
Grid generation: A view from the trenches
This paper presents 'A view from the trenches' on CFD grid generation from a Pratt & Whitney perspective. We anticipate that other organizations have similar views. We focus on customer expectations and the consequent requirements. We enunciate a vision for grid generation, discuss issues that developers must recognize
