Verification of the Accuracy of Sample-Size Equation Calculations for Visual Sample Plan Version 0.9C

Description: Visual Sample Plan (VSP) is a software tool being developed to facilitate the design of environmental sampling plans using a site-map visual interface, standard sample-size equations, a variety of sampling grids and random sampling plans, and graphs to visually depict the results to the user. This document provides comparisons between sample sizes calculated by VSP Version 0.9C, and sample sizes calculated by test code written in the S-Plus language. All sample sizes calculated by VSP matched the independently calculated sample sizes. Also the VSP implementation of the ELIGPRID-PC algorithm for hot spot probabilities is shown to match previous results for 100 standard test cases. The Conclusions and Limitations section of this document lists some aspects of VSP that were not tested by this suite of tests and recommends simulation-based enhancements for future versions of VSP.

Vendor System Vulnerability Testing Test Plan

Description: The Idaho National Laboratory (INL) prepared this generic test plan to provide clients (vendors, end users, program sponsors, etc.) with a sense of the scope and depth of vulnerability testing performed at the INL’s Supervisory Control and Data Acquisition (SCADA) Test Bed and to serve as an example of such a plan. Although this test plan specifically addresses vulnerability testing of systems applied to the energy sector (electric/power transmission and distribution and oil and gas systems), it is generic enough to be applied to control systems used in other critical infrastructures such as the transportation sector, water/waste water sector, or hazardous chemical production facilities. The SCADA Test Bed is established at the INL as a testing environment to evaluate the security vulnerabilities of SCADA systems, energy management systems (EMS), and distributed control systems. It now supports multiple programs sponsored by the U.S. Department of Energy, the U.S. Department of Homeland Security, other government agencies, and private sector clients. This particular test plan applies to testing conducted on a SCADA/EMS provided by a vendor. Before performing detailed vulnerability testing of a SCADA/EMS, an as delivered baseline examination of the system is conducted, to establish a starting point for all-subsequent testing. The series of baseline tests document factory delivered defaults, system configuration, and potential configuration changes to aid in the development of a security plan for in depth vulnerability testing. The baseline test document is provided to the System Provider,a who evaluates the baseline report and provides recommendations to the system configuration to enhance the security profile of the baseline system. Vulnerability testing is then conducted at the SCADA Test Bed, which provides an in-depth security analysis of the Vendor’s system.b a. The term System Provider replaces the name of the company/organization providing the system being evaluated. This can be the system ...

Thundershowers: A Novella, with a Commentary

Description: Thundershowers, an original novella, represents one person's perception of relationships between women and men. The first-person narrator, Anna Slone, records her limited observations of married and unmarried couples while she pursues her own involvement with a man. She observes nothing admirable in any of the relationships between men and women in the story, and her own romance falls short of her expectations. The only nurturing love that she records passes between herself and two other women, her mother and a friend. Thundershowers is not meant to be a suggestion that all woman-man relationships are soulless or that real love can exist only between women. Set in a Colorado resort, the action focuses on several concurrent love-interests, including a faltering marriage, a traditional marriage, the engagement of two young lovers, a lighthearted sexual affair, and the short-lived but painful romance of Anna and a man whom she meets at the resort.

Recommended Practice for Securing Control System Modems

Description: This paper addresses an often overlooked “backdoor” into critical infrastructure control systems created by modem connections. A modem’s connection to the public telephone system is similar to a corporate network connection to the Internet. By tracing typical attack paths into the system, this paper provides the reader with an analysis of the problem and then guides the reader through methods to evaluate existing modem security. Following the analysis, a series of methods for securing modems is provided. These methods are correlated to well-known networking security methods.

Power Systems Control Architecture

Description: A diagram provided in the report depicts the complexity of the power systems control architecture used by the national power structure. It shows the structural hierarchy and the relationship of the each system to those other systems interconnected to it. Each of these levels provides a different focus for vulnerability testing and has its own weaknesses. In evaluating each level, of prime concern is what vulnerabilities exist that provide a path into the system, either to cause the system to malfunction or to take control of a field device. An additional vulnerability to consider is can the system be compromised in such a manner that the attacker can obtain critical information about the system and the portion of the national power structure that it controls.

The Poetry of Emily Dickinson and Edna St. Vincent Millay

Description: Millay and Dickinson, born more than sixty years apart, were subject to vastly different influences and environments, although their homes were in the same geographic area. Their poetry reflects the difference of their times and their own temperament, but both wrote from a great depth and understanding of feeling and experience about subjects common to all mankind - death, love, anguish, the significance of nature.

William Livingston: Revolutionary War Governor of New Jersey

Description: This investigation is concerned with the importance of the role that William Livingston played in the struggle for American independence. Two methods were used to present this role. First, a narrative account describes his work as governor of the state of New Jersey. Second, subjective opinions of his contemporaries and others evaluate the effectiveness of his work.

Visual Sample Plan Version 1.0 User's Guide

Description: This user's guide describes Visual Sample Plan (VSP) Version 1.0 and provides instructions for using the software. VSP selects the appropriate number and location of environmental samples to ensure that the results of statistical tests performed to provide input to environmental decisions have the required confidence and performance. VSP Version 1.0 provides sample-size equations or algorithms needed by specific statistical tests appropriate for specific environmental sampling objectives. The easy-to-use program is highly visual and graphic. VSP runs on personal computers with Microsoft Windows operating systems (95, 98, Millenium Edition, 2000, and Windows NT). Designed primarily for project managers and users without expertise in statistics, VSP is applicable to any two-dimensional geographical population to be sampled (e.g., surface soil, a defined layer of subsurface soil, building surfaces, water bodies, and other similar applications) for studies of environmental quality.

The Poetic Voice and the Romantic Tradition in the Poetry of Maxine Kumin

Description: The purpose of this study is to explore elements of the Romantic tradition in the poetry of Maxine Kumin and the poetic voice of Ms. Kumin as she writes in this tradition. The poet's choice of poetic-persona illustrates a growth of the consciousness, an identity of self. Of particular interest is the poet's close interaction with nature and use of natural symbols and images. A principal motif in Kumin's poetry is the common man. Another theme is the poet's role in the family. In poems exalting nature and the person who lives in simple and close interaction with nature, a number of men from the past and present are subjects of Kumin's poetry.

Self-Alienating Characters in the Fiction of John Steinbeck

Description: The primary purpose of this study is to show that John Steinbeck's concern with alienation is pervasive and consistent from the beginning of his career as a writer until the end. The pervasiveness of his concern with alienation is demonstrated by examining his two early collections of short stories and by showing how alienated characters in these stories resemble alienated characters in all the author's major works of fiction. Since much confusion surrounds the meaning of the word "alienation," it is necessary to begin with a definition of "alienation" as it is used to discuss Steinbeck. An alienated character in Steinbeck's fiction is a person who is separated from another person, group of persons, society, or the person's ideal self. This study is concerned with characters who create their own alienation rather than with those who are merely helpless victims.

“Night Shaping Itself” and Forty Other Poems

Description: The forty-one poems comprising this thesis are written in a variety of styles and reflect my general international eclecticism. The most prominent influences on my work are ancient Chinese verse, as exemplified by the poems for N., and Zen tanka and haiku, as exemplified by "Detail from a Cubistic Autobiography." Largely imagistic rather than narrative, the poems were conceived in an effort to record my experiences and to define my reactions to those experiences.

Selected Poems: Does This Pen Write?

Description: This thesis is a collection of poetry written between 1970 and 1975. The quality of the poems is admittedly uneven, but the inclusion of earlier, weaker poems may indicate a progression in the areas of flexibility, control of material, and strength of poetic voice. The poems are arranged into five sections, entitled "Love," "Rabbits," Poetry about Poetry," "Religion and Ancestors," and "Henry. Poems collected here are intended to demonstrate that experimentation with various forms contributes to an increased ability to control poetic material and technique. By confining a poem to particular forms, one is forced to be more creative, imaginative, and exact. Both control and flexibility are important in contemporary poetry, and my hope is that the following poems demonstrate a balance of those qualities.

Emily and the Child: An Examination of the Child Image in the Work of Emily Dickinson

Description: The primary sources for this study are Dickinson's poems and letters. The purpose is to examine child imagery in Dickinson's work, and the investigation is based on the chronological age of children in the images. Dickinson's small child exists in mystical communion with nature and deity. Inevitably the child is wrenched from this divine state by one of three estranging forces: adult society, death, or love. After the estrangement the state of childhood may be regained only after death, at which time the soul enters immortality as a small child. The study moreover contends that one aspect of Dickinson's seclusion was an endeavor to remain a child.
