Little Boxes: The Simplest Demonstration of the Failure of Einstein's Attempt to Show the Incompleteness of Quantum Theory

The failure of Einstein's co-authored "EPR" attempt to show the incompleteness of quantum theory is demonstrated directly for spatial degrees of freedom using only elementary notions. A GHZ construction is realized in the position properties of three particles whose quantum waves are distributed over three two-chambered boxes. The same system is modeled more realistically using three spatially separated, singly ionized hydrogen molecules.Comment: To appear in American Journal of Physic

Induction without Probabilities

A simple indeterministic system is displayed and it is urged that we cannot responsibly infer inductively over it if we presume that the probability calculus is the appropriate logic of induction. The example illustrates the general thesis of a material theory of induction, that the logic appropriate to a particular domain is determined by the facts that prevail there

How Hume and Mach Helped Einstein Find Special Relativity

In recounting his discovery of special relativity, Einstein recalled a debt to the philosophical writings of Hume and Mach. I review the path Einstein took to special relativity and urge that, at a critical juncture, he was aided decisively not by any specific doctrine of space and time, but by a general account of concepts that Einstein found in Hume and Mach’s writings. That account required that concepts, used to represent the physical, must be properly grounded in experience. In so far as they extended beyond that grounding, they were fictional and to be abjured (Mach) or at best tolerated (Hume). Einstein drew a different moral. These fictional concepts revealed an arbitrariness in our physical theorizing and may still be introduced through freely chosen definitions, as long as these definitions do not commit us to false presumptions. After years of failed efforts to conform electrodynamics to the principle of relativity and with his frustration mounting, Einstein applied this account to the concept of simultaneity. The resulting definition of simultaneity provided the reconceptualization that solved the problem in electrodynamics and led directly to the special theory of relativity

Reforming Immigration Law to Allow More Foreign Student Entrepreneurs to Launch Job-Creating Ventures in the United States

As universities move toward a more experiential approach to entrepreneurship education, many academic units and cross-campus entrepreneurship programs are encouraging their students to actively engage with the curriculum and apply the skills they learn. One such approach is to have students start their own businesses before they graduate. In addition to enhancing their education, participation in the planning, launch and operation of a start-up venture can lead directly to the creation of new jobs for many other individuals. Unfortunately, being the founder of a start-up venture in the United States proves complicated for foreign students in our colleges and universities. Across the country, both undergraduate and graduate entrepreneurship students desiring to participate actively in a startup face vexing immigration law challenges. This paper outlines some of the barriers that foreign student entrepreneurs face, and describes how bipartisan legislation would help to address some of these roadblocks

The business process modelling ontology

In this paper we describe the Business Process Modelling Ontology (BPMO), which is part of an approach to modelling business processes at the semantic level, integrating knowledge about the organisational context, workflow activities and Semantic Web Services. We harness knowledge representation and reasoning techniques so that business process workflows can: be exposed and shared through semantic descriptions; refer to semantically annotated data and services; incorporate heterogeneous data though semantic mappings; and be queried using a reasoner or inference engine. In this paper we describe our approach and evaluate BPMO through a use case

An introduction to sensitivity assessment of simulation models

In view of increasing application of sensitivity assessment (SA) to environmental simulation models, a relatively short, informal introduction to aims and methods of SA is given. Their variety, motivation and scope are illustrated by outlines of a broad selection of approaches. Methods based on derivatives, algebraic analysis, sparse sampling, variance decomposition, Fourier analysis and binary classification are included

2012 State of Metropolitan Housing Report

This report updates Metropolitan Housing Coalition's nine annual measures of fair and affordable housing for the Louisville, KY Metropolitan Statistical Area: Concentration of Subsidized Housing; Housing Segregation; Renters with Excessive Cost Burden; Production and Rehabilitation of Affordable Housing; Homeownership Rate; Access to Homeownership; Foreclosures; Homelessness; and Community Development Block Grants (CDBG) and HOME Funds.The 2012 State of Metropolitan Housing Report clearly demonstrates Metropolitan Louisville's growing need for safe, fair, and affordable housing. For the first time, the tenth annual State of Metropoltian Housing Report includes data on the number of children experiencing homelessness in the MSA's public school systems; before MHC reported only on Jefferson County Public Schools.The 2012 report also includes a focus topic: vacant properties and their impact on the community as well as current efforts and best practices that to address this issue. Additionally, the report also drills down into the Neighborhood Stabilization Program, a federal program designed to address the issue of vacant properties, and how it was used in Louisville

Panel Mounted SFF-TA-1002 Connectors with Common Mounting Slot

SFF-TA-1002 is a new standard connector standardized under SNIA and adopted by multiple industry bodies such as Gen-Z, EDSFF, JEDEC and OCP. The signal integrity requirements on future high speed systems (32Gbps+) will require more directly cabled solutions that bypass host PCBs and midplanes. This invention details an SFF-TA-1002 implementation that can be panel mounted and deployed into standard backplanes constructed of either PCB or sheet metal
