Spending Versus Tax Cuts: Who Pays the Cost of Political Compromise?

President Obama and the Democratic leadership will undoubtedly have to make some political compromises in order to get a stimulus package through Congress. However, it is important to keep in mind that there will be real costs associated with these compromises insofar as they result in a less effective stimulus package. A less effective package will mean less economic growth, which will, in turn, mean that fewer people will have jobs

Hilbert's machine and the Axiom of Infinity

Hilbert's machine is a supertask machine inspired by Hilbert's Hotel whose functioning leads to a contradiction that compromises the Axiom of Infinity

Purity or pragmatism? : Reflecting on the use of systematic review methodology in development

Systematic review methodology pioneered in health care has been increasingly applied to development questions of importance in lower- and middle-income countries. This paper reports one such review on the topic of microfinance in sub-Saharan Africa and reflects on the number of pragmatic methodological compromises made when applying the method to a new field. These compromises relate to multidisciplinary teamwork, application of regional filters, drawing on evidence from additional study types and exploring mechanisms for change through the development and testing of a causal pathway. The paper concludes that a pragmatic rigorous approach to systematically reviewing evidence of effectiveness is needed for international development

Thermal scale modeling

Complex system study data indicate that factors associated with multilayer insulation pose major problem in scale modeling, that numerical analysis aids correction for known compromises of scaling criteria, and that probable errors in scale modeling experiments fall within range predicted by statistical analysis

Sustainability without compromises

There is a very small amount of detailed experience available regarding instrument transformers filled with biodegradable liquids. In an effort to make their entire high-voltage product line more sustainable, thus providing considerable added value, Končar – Instrument Transformers, decided to implement all available biodegradable liquid technologies into their instrument transformers. While it may seem trivial, there is extensive dielectric, thermal, climatic and material compatibility testing that needs to be done, before a dielectric liquid can be approved for use. That being said, the aim of this article is to give a brief overview of performed tests and gathered data. The focus will be on prototypes filled with two different types of biodegradable liquids: synthetic ester MIDEL 7131 and bio-hydrocarbonbased oil Nynas Nytro BIO 300X. Both of the liquids successfully completed the entire testing cycle and are considered approved for commercial use

Integrated series active filter for aerospace flight control surface actuation

The paper investigates integrated series active filters to satisfy aircraft power quality benchmarks and underlying design compromises. Advantages include reduced component count and retrofitting capability. Further insights into the merits of the proposed solution are included, along with representative results from a prototype system
