Abstract Housing affordability is the main policy challenge for most large cities in world. Zoning changes, rent control, housing vouchers, and tax credits are levers employed by policymakers. How effective they at combatting crisis? We build a dynamic stochastic spatial equilibrium model to evaluate effect of these policies on well-being its citizens. The endogenizes house prices, rents, const...

In this study, we address the durability of the brain, which is able to operate in various imperfect situations. In our previous research, we have proposed a new network structure called the “Affordable Neural Network”, where affordable neurons in the hidden layer of the feedforward neural network reflect important aspects of the real brain mechanism. We consider that the concept of the afforda...

In November 2002, the Common Market for Eastern and Southern Africa (COMESA), Africa’s major free trade bloc, applied to the World Trade Organization (WTO) for the right to manufacture low-cost drugs to treat AIDS. The Secretary General of the Organization Erastus Mwencha, in announcing this move, said that drugs must be cheaper as the world could not continue to see people dying for the sake o...

Joint Vision 2010 describes an approach about joint warfare of the future, and it depends on and highlights the contributions of air power. Accordingly, the Air Force’s vision of Global Engagement flows from Joint Vision 2010. The Air Force’s Strategic Plan outlines the core competencies that are necessary for Global Engagement. The capability for attaining the desired capabilities and goals of...

In July 2012, the Supreme Court upheld the constitutionality of the Patient Protection and Affordable Care Act (PPACA). The Court thus ended one phase in the political and legal battle over health reform. Yet in doing so, it opened a new front. In a notable departure from post– New Deal commerce clause jurisprudence, the Court ruled that the federal government could not require states that rece...

High cost and complexity of commercial X-ray computed tomography systems act as a barrier to the adoption of such technology by small and medium sized companies. The work presented here attempts to address these issues through the development of affordable solutions for both CT reconstruction and X-ray projection data set acquisition. Introduction The Precision Measurements Group at SIMTech has...

Turbidity is an internationally recognized criterion for assessing drinking water quality, because the colloidal particles in turbid water may harbor pathogens, chemically reduce oxidizing disinfectants, and hinder attempts to disinfect water with ultraviolet radiation. A turbidimeter is an electronic/optical instrument that assesses turbidity by measuring the scattering of light passing throug...
