Anytime planning for agent behaviour

For an agent to act successfully in a complex and dynamic environment (such as a computer game)it must have a method of generating future behaviour that meets the demands of its environment. One such method is anytime planning. This paper discusses the problems and benefits associated with making a planning system work under the anytime paradigm, and introduces Anytime-UMCP (A-UMCP), an anytime version of the UMCP hierarchical task network (HTN) planner [Erol, 1995]. It also covers the necessary abilities an agent must have in order to execute plans produced by an anytime hierarchical task network planner

So No Damn Politician Ever Scrap It: The Constitutional Protection of Social Security Benefits

Is the nation’s old-age pension system bankrupt? Each year brings repeated warnings of a need for immediate reform. Yet somehow, reasonable people and even experts dispute both the severity of the crises and the scope of the reforms, if any, that ought to be taken. Completely overlooked in the debate, however, are the legal and even constitutional limits to any reformation plan. President Roosevelt intended to create a program that would withstand political compromise—a program that would create a “legal, moral, and political right” to the receipt of benefits. Nearly seventy years after Social Security’s creation, we must ask: Did Roosevelt succeed

Clayville Rural Life Center and Museum - Publications Series II - Research Report #05: Inns and Taverns in the Midwest - Typical Functions, Forms, and Layouts

Part I of this report explores the functions of typical inns and taverns. It established the bases for setting up a typical inventory of furniture, cookware, eating utensils, and all the other likely necessary and not-so-necessary items which would be found in a combined farm home and inn. Part II presents the results of field work on the form and layout of surviving structures in Illinois. It has several sections on the architectural content and the probable use of the space inside the inn. 109p.National Endowment for the Humanitiespublished or submitted for publicationnot peer reviewe

Exploring Design Space For An Integrated Intelligent System

Understanding the trade-offs available in the design space of intelligent systems is a major unaddressed element in the study of Artificial Intelligence. In this paper we approach this problem in two ways. First, we discuss the development of our integrated robotic system in terms of its trajectory through design space. Second, we demonstrate the practical implications of architectural design decisions by using this system as an experimental platform for comparing behaviourally similar yet architecturally different systems. The results of this show that our system occupies a "sweet spot" in design space in terms of the cost of moving information between processing components

A qualitative study of the health experience of gypsy travellers in the UK with a focus on terminal illness

Aim To understand the experience of terminal care and health care access for Gypsy Travellers, to inform palliative and primary care service provision. Background Little contemporary research of UK English Romany Gypsy Travellers is available. This ethnic group is often overlooked in ethnic minority health research. Methods Access to Gypsy Traveller communities was through non-health care channels and required the development of trust through repeated contact over time. English Romany Gypsy Travellers at two Traveller sites participated in face-to-face contacts. Data collection was through field observation and seven semistructured interviews with Gypsy Traveller women who had experience of caring for relatives who were dying. In addition, data were collected over two years through discussion in a members-only Gypsy and Traveller interest e-mail forum. Findings The culture of Gypsy Travellers is distinct but diverse. Hygiene is important as is discretion and sensitivity to the information requirements of the patient and family. Gypsy Travellers are aware that their mobility (voluntary or enforced) can negatively impact on health care. Home care for the terminally ill is often preferred to hospital care often due to poor understanding of their cultural and personal needs by health care professionals and due to an aversion to ‘bricks and mortar’. Care may be provided by the extended family. Palliative care provision should consider the needs of Gypsy Travellers including respect for their culture and support for caring at home

Experimental Study of Ultra Shallow Floor Beams (USFB) with Perforated Steel Sections

ABSTRACT: In modern building construction design, floor spans are becoming longer. Hence, steel framed structures have become more competitive when compared with traditional reinforced concrete framed buildings. In order to minimise the structural section of the composite sections, and for economic reasons, steel perforated beams are designed to act compositely with the floor slab. When the concrete slab lies within the steel flanges, as in the Ultra Shallow Floor Beam (USFB), there is an additional benefit when considering fire resistance. The aim of this study is to investigate the contribution of the concrete in composite cellular beams in the case where the concrete slab lies between the beam flanges of a steel section, when resisting vertical shear forces. The concrete between the flanges enhances the load-carrying capacity by providing a load path to transfer the shear force. Four specimens of steel-concrete composite beams with web openings in the steel section were tested in this study. One bare steel section with web openings was also tested as a comparison. This is the first such investigation of the failure mode under shear resistance (Vierendeel action) of the Ultra Shallow Floor Beam. In the test specimens, the web opening diameter is 76% of the beam depth, which is the largest currently available. This represents the worst case in terms of Vierendeel bending forces generated in the vicinity of the web openings. The smaller the hole is, the easier it is for the trapped concrete between the flanges to transfer shear across the opening. The results from the composite beam tests show a significant increase in shear resistance. The percentage of the shear capacity improvement of the particular case is presented herein as well as the failure mode of the composite beams. The shear enhancement demonstrated in this study has been utilised software that is used in design practice
