Base heating methodology improvements, volume 1

This document is the final report for NASA MSFC Contract NAS8-38141. The contracted effort had the broad objective of improving the launch vehicles ascent base heating methodology to improve and simplify the determination of that environment for Advanced Launch System (ALS) concepts. It was pursued as an Advanced Development Plan (ADP) for the Joint DoD/NASA ALS program office with project management assigned to NASA/MSFC. The original study was to be completed in 26 months beginning Sep. 1989. Because of several program changes and emphasis on evolving launch vehicle concepts, the period of performance was extended to the current completion date of Nov. 1992. A computer code incorporating the methodology improvements into a quick prediction tool was developed and is operational for basic configuration and propulsion concepts. The code and its users guide are also provided as part of the contract documentation. Background information describing the specific objectives, limitations, and goals of the contract is summarized. A brief chronology of the ALS/NLS program history is also presented to provide the reader with an overview of the many variables influencing the development of the code over the past three years

The Update, September 7, 2009

The Update is a bi-weekly web newsletter published by the Iowa Department of Public Health's Bureau of Family Health. It is posted the second and fourth week of every month, and provides useful job resource information for departmental health care professionals, information on training opportunities, intradepartmental reports and meetings, and additional information pertinent to health care professionals

Degrees of Freedom: Expanding College Opportunities - for Currently and Formerly Incarcerated Californians

This report begins with a background on the higher education and criminal justice systems in California. This background section highlights the vocabulary and common pathways for each system, and provides a primer on California community colleges. Part II explains why California needs this initiative. Part III presents the landscape of existing college programs dedicated to criminal justice-involved populations in the community and in jails and prisons. This landscape identifies promising strategies and sites of innovation across the state, as well as current challenges to sustaining and expanding these programs. Part IV lays out concrete recommendations California should take to realize the vision of expanding high-quality college opportunities for currently and formerly incarcerated individuals. It includes guidelines for developing high-quality, sustainable programs, building and strengthening partnerships, and shaping the policy landscape, both by using existing opportunities and by advocating for specific legislative and policy changes. Profiles of current college students and graduates with criminal records divide the sections and offer first-hand accounts of the joys and challenges of a college experience

The Importance Of Community: Investing In Effective Community-Based Crime Prevention Strategies

After more than a year of listening to our community, researching evidence-based practices, and evaluating our own efforts, 'The Importance of Community' inaugural report unequivocally asserts that our greatest potential of reducing homicides and incarceration as a result of committing a crime is deeply rooted in collective community action and targeted interventions aimed at serving narrowly defined populations. In this report, The Indianapolis Foundation will summarize years of community-based recommendations and provides a specific community investment plan based on multiple community convenings, crime prevention related reports, and listening to our community

A Neural Architecture for Generating Natural Language Descriptions from Source Code Changes

We propose a model to automatically describe changes introduced in the source code of a program using natural language. Our method receives as input a set of code commits, which contains both the modifications and message introduced by an user. These two modalities are used to train an encoder-decoder architecture. We evaluated our approach on twelve real world open source projects from four different programming languages. Quantitative and qualitative results showed that the proposed approach can generate feasible and semantically sound descriptions not only in standard in-project settings, but also in a cross-project setting.Comment: Accepted at ACL 201

Structured Review of the Evidence for Effects of Code Duplication on Software Quality

This report presents the detailed steps and results of a structured review of code clone literature. The aim of the review is to investigate the evidence for the claim that code duplication has a negative effect on code changeability. This report contains only the details of the review for which there is not enough place to include them in the companion paper published at a conference (Hordijk, Ponisio et al. 2009 - Harmfulness of Code Duplication - A Structured Review of the Evidence)
