Integrated oxygen recovery system

Life Systems has conceptualized an innovative Integrated Oxygen Recovery System (IORS) applicable to advanced mission air revitalization. The IORS provides the capability to electrochemically generate metabolic oxygen (O2) and recover O2 from the space habitat atmosphere via a carbon dioxide (CO2) reduction process within a single assembly. To achieve this capability, the IORS utilizes a Solid Metal Cathode (SMC) water electrolysis unit that simultaneously serves as the Sabatier CO2 reduction reactor. The IORS enables two major life support systems currently baselined in closed loop air revitalization systems to be combined into one smaller, less complex system. This concept reduces fluidic and electrical interface requirements and eliminates a hydrogen (H2) interface. Life Systems is performing an evaluation of the IORS process directed at demonstrating performance and quantifying key physical characteristics including power, weight, and volume. The results of the checkout, shakedown, and initial parametric tests are summarized

Beyond the War on Terrorism: Towards the New Intelligence Network

In Terrorism, Freedom, and Security, Philip B. Heymann undertakes a wide-ranging study of how the United States can - and in his view should - respond to the threat of international terrorism. A former Deputy Attorney General of the United States Department of Justice ( DOJ ) and current James Barr Ames Professor of Law at Harvard Law School, Heymann draws on his governmental experience and jurisprudential background in developing a series of nuanced approaches to preventing terrorism. Heymann makes clear his own policy and legal preferences. First, as his choice of subtitle suggests, he firmly rejects the widely used metaphor of the United States engaging in a war on terrorism. Heymann views this mental model and the policies it spawns or is said to justify as, at best, incomplete, and, at worst, ineffective in preventing terrorist attacks and harmful to democracy in the United States (pp. 19-36). Second, Heymann advocates the paramount importance of intelligence to identify and disrupt terrorists\u27 plans and to prevent terrorists from attacking their targets (p. 61). Heymann observes that the United States needs both tactical intelligence to stop specific terrorist plans and strategic intelligence to understand the goals, organization, resources, and skills of terrorist organizations (p. 62)

ON ILLOCUTIONARY LOGIC AS A TELECOMMUNICATIONS LANGUAGE

Interorganizational telecommunications-mediated messages are nearly always expressed either in natural language (via telephone, telex, electronic mail, etc) or through specific protocols developed for the application at hand. Natural language expression is powerful, flexible, equivocal, and not generally machine readable. Specific protocols have a limited expressive power, are inflexible, can be unequivocal, and are machine readable. This paper commences an exploration of the possibility of using a formal language for interorganizational messaging. Such a strategy promises to combine the virtues of natural language and of specific protocols for communication. Formal logic is a natural basis for such a language. Recent developments in illocutionary logic (an extension of predicate logic) bid fair to provide a sound basis for a formal language for business communications. The paper discusses these concepts and how they might be implemented

FINDING INTERNATIONAL CONTRACTING OPPORTUNITIES: AI EXTENSIONS TO EDI

Electronic Data Interchange (EDI) offers a telecommunications infrastructure for inter-business communications. This paper proposes a particular use of that infra-structure to aid firms in identifying contracting opportunities, particularly where international trade is involved. We focus on two aspects of this problem: navigating the legal procedures relating to such contracts and managing the multi-lingual communications

Performative, Informative and Emotive Systems The First Piece of the PIE

This paper distinguishes computer and communications systems that\u27perform\u27 fr om those that\u27inform\u27 and those that deal with emotive aspects of problems. It indicates some of the ways that peformative systems seem to differ from the other kinds, why this distinction is important to both users and designers, and suggests research-some of it currently underway-to investigate this area. Results from this research will allow us to improve existing performative systems and to expand the domain of their application
