Design of a power-aware digital image rejection receiver

This paper deals with and details the design of a power-aware adaptive digital image rejection receiver based on blind-source-separation that alleviates the RF analog front-end impairments. Power-aware system design at the RTL level without having to redesign arithmetic circuits is used to reduce the power consumption in nomadic devices. Power-aware multipliers with configurable precision are used to trade-off the image-rejection-ratio (IRR) performance with power consumption. Results of the simulation case studies demonstrate that the IRR performance of the power-aware system is comparable to that of the normal implementation albeit degraded slightly, but well within the acceptable limits.

Handling the transfer of power: a note on the 1964 origins of the Douglas‐Home rules

Opposition is rarely a good preparation for government. The only post‐war government to enter office confident, well‐acquainted with the Civil Service and with a fund of administrative experience to draw on was the Attlee administration formed in 1945. The longer a party spends in opposition the more these assets disappear. Labour, by the end of the long period of Conservative rule in 1951–64, was largely unfamiliar with the burdens of office. This formed the background to the formulation of the Douglas‐Home rules, whereby informal contact is permitted between the Civil Service and the Opposition in advance of a general election. Since 1964 this arrangement has gradually become more extensive (especially after Neil Kinnock complained that the period for contact was too brief during the run‐up to the 1992 election) and more formalised. In late 1993 John Major agreed that contacts could be made from early 1996 in advance of the next election, rather than only during the last six months of a parliament, as had by then become the convention.’ The object of this short paper is, however, to explain how these rules originated.

Rethinking crises and the accretion of executive power: the “War on Terror” and conditionality evidence from seven political systems

External shocks to democratic systems are likely to threaten the stability of relations between the executive and the representative assembly. This article investigates the impact of the so-called “war on terror” on executive-assembly relations in comparative perspective. We analyze data from seven countries, which varied in terms of form of government, level of democracy, culture, social structure, and geographic location, to evaluate its effects. We find that whereas in some systems the “war on terror” altered the balance of power between the executive and the assembly, in other cases the extant balance of power was preserved. We postulate various conditions under which the constitutionally sanctioned balance of power is most likely to be preserved in times of crisis.
