Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Scheduling transmissions in a network
Journal of Algorithms, 1985Summary: Consider k stations wishing to transmit messages over a network of channels to a common receiver. The capacity of a channel is the maximum amount of data which can be transmitted in a time unit. In addition to the transmission stations, the network contains switching nodes.

Optical Transmission Modules for Intraoffice Transmission Networks
IEEE Journal on Selected Areas in Communications, 1986This paper considers the requirements of, and proposes technical solutions for, the optical transmission modules used in intraoffice links. A novel crosstalk noise measurement procedure is proposed along with a quantitative evaluation method for crosstalk prevention which is very important in the development of compact modules.

Gigabit networking on the public transmission network
IEEE Communications Magazine, 1992The evolution of the public network, from gigabit transmission to gigabit networking, is examined from the perspective of a telephone operating company. The relationship between technology push and service pull and the impact that both have on network architectures are considered. The network transition is discussed to identify ways of cost effectively

Concurrent transmissions in broadcast networks
1984A linear time algorithm for determining the maximal number of collision-free transmissions in an arbitrary series-parallel network is developed. The method operates by a recursive contraction of the network to a single edge; during this contraction process, information is retained concerning each of the subnetworks which has been eliminated.

Optimizing Network Data Transmission
Third International Conference on Information Technology: New Generations (ITNG'06), 2006Theoretically, transmitting compressed data will optimize bandwidth use. Internet traffic is rarely compressed, thus this benefit is not fully realized. Compression algorithms should be increasingly effective as file size increases, up to a maximum determined by the data type and compression algorithm. However, these efficiencies are also not achieved.

Transmissions in a network with capacities and delays
Networks, 1999Summary: We examine the problem of transmitting in minimum time a given amount of data between a source and a destination in a network with finite channel capacities and nonzero propagation delays. In the absence of delays, the problem has been shown to be solvable in polynomial time. In this paper, we show that the general problem is NP-complete.

Feasibility of DC transmission networks
2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies, 2011This paper examines the current status of technology and discusses technical options for developing DC transmission grids. The fast advances in VSC HVDC, the recent offshore VSC projects, the experience with multiterminal HVDC and recent development of fast DC circuit breakers bring large meshed DC grids closer to reality.
