This book examines the use of wedge strategies, a form of divisive statecraft designed to isolate adversaries from allies and potential supporters to gain key advantages. With a multidimensional argument about the power of accommodation in competition, and a survey of alliance diplomacy around both world wars, the book artfully analyzes the past and ...

2012 International Conference on Computational Problem-Solving (ICCP), 2012
A ultra-wideband (UWB) Wilkinson power divider with step impedance resonators (SIR) was presented in this paper. It was working in the ultra wide frequency band (3.1GHz – 10.6GHz) by modifying the traditional two sections Wilkinson power divider. The simulation results of the power divider shows a good performance.

China: Power Combiners/Dividers
IEEE Microwave Magazine, 2011Several types of coaxial-waveguide power dividers/combiners are summarized in this article. These types of coaxial-waveguide power dividers/combiners have several advantages, such as wide bandwidth, large numbers of power-dividing ports, excellent input impedance matching, low insertion loss, and good balance of amplitude and phase at output ports.

Radial Wilkinson power divider
2011 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2011), 2011The objective of this study was to develop a 1:4 power divider with high levels of symmetry and isolation between the ports. While the Wilkinson type divider offers high isolation between the ports and the radial divider offers high tracking between the ports, it is sought that a combination of the two concepts will comply with both requirements.

A Varactor Based Frequency-Tunable Power Divider With Unequal Power Dividing Ratio
IEEE Microwave and Wireless Components Letters, 2016An unequal power divider with tunable operating frequency is proposed for the first time, in which the operating frequency can be tuned over 100% around the center frequency. The theoretical analysis for the characteristic impedance and the electrical length are presented.

DIVIDED POWER AND ΕΥΝΟΜΙΑ: DELIBERATIVE PROCEDURES IN ANCIENT SPARTA
The Classical Quarterly, 2017Spartan institutions were pictured as a model of political stability from the Classical period onwards. The so-called Spartan ‘mirage’ did not involve only its constitutional order but also social and economic institutions. Xenophon begins hisConstitution of the Lacedaemoniansby associating Spartan fame with thepoliteiaset up by Lycurgus, which made ...
