Knowledge-Based Task Structure Planning for an Information Gathering Agent

An effective solution to model and apply planning domain knowledge for deliberation and action in probabilistic, agent-oriented control is presented. Specifically, the addition of a task structure planning component and supporting components to an agent-oriented architecture and agent implementation is described. For agent control in risky or uncertain environments, an approach and method of goal reduction to task plan sets and schedules of action is presented. Additionally, some issues related to component-wise, situation-dependent control of a task planning agent that schedules its tasks separately from planning them are motivated and discussed.

Työvaiheen kustannustietojen analysointi ja hyödyntäminen

Rakennushankkeen päämääränä on toteuttaa hanke sopimusten ja suunnitelmien mukaisesti. Koko hankkeen kustannus- ja aikatavoite eivät riitä ohjaamaan tuotantoa, vaan projektien hallinnan helpottamiseksi kokonaisuus on pilkottava osiin, tehtäviin, jotka suunnitellaan, budjetoidaan ja valvotaan itsenäisinä kokonaisuuksina. Työtehtävä on ajallisesti yhtenäinen työpanoksia vaativa kokonaisuus, jonka kustannus- ja aikatavoitteet voidaan määritellä. Yksittäisen tehtävän tavoitteet, vaatimukset ja aloitusedellytykset selkeytetään ja varmistetaan tehtäväsuunnittelulla. Tehtäväsuunnittelu on tapa suunnitella ja ohjata yksittäisiä tehtäviä ja varmistaa niiden kautta, että koko työmaan tuotanto etenee suunnitelmien ja tavoitteiden mukaisesti sekä saavuttaa sille asetetut kokonaistavoitteet. Yksi tehtäväsuunnittelun osa on tehtävän kustannusten tarkkailu, jolla varmistetaan, että työvaiheen tuotanto etenee suunnitellulla tavalla ja, että tuotantosuunnitelma ja tavoite saavutetaan. Vaikka uudisrakennuskohteissa tehtävien työmenekit toistuvat suunnilleen samoina, saattavat työmaalla toteutuneet kustannukset erota laskennan tavoitearviosta oleellisesti. Tämän insinöörityön tavoitteena oli selvittää YIT Rakennus Oy:n tavoitearvioiden, tuotettujen tehtäväsuunnitelmien mukaisten kustannusten, tarkekirjausten ja toteutuneiden kustannusten välisiä eroja, sekä yhdistää tietoketju työmaalta tehtäväsuunnitelman ja tarkekirjauksen kautta kustannuslaskentaan niin, että se toimii myös työmaan toimintaa parantavana prosessina. Samalla tehtävänä oli myös parantaa YIT Rakennus Oy:n tehtäväsuunnitelma- ja tarkekirjauspohjia. Vertaamalla neljän yksittäisen tehtävän tavoitearvion, tehtäväsuunnitelmassa tarkastettujen suunnitelmien ja kustannusten ja toteutuneiden kustannusten eroja eri kustannuslajeilla ja analysoimalla niitä, saatiin selville, mistä nämä erot voivat johtua ja mitkä ovat yleisimmät syyt eroihin tehtävästä riippumatta. Selkeitä syitä tehtävien tavoitearvioiden, tehtäväsuunnitelmien mukaisten kustannusten ja toteutuneiden kustannusten välisiin eroihin löytyi yhteensä 15. Näistä useimmiten toistuivat laskennan tavoitearviosta poikkeava urakkamuoto, keskituntiansion suuruus sekä aikataulu- ja materiaalimuutokset. Työssä tehdyt uudet tehtäväsuunnitelma-, tarkekirjaus- ja palauteanalyysipohjat yhdistävät tietoketjun työvaiheiden kustannuksista työmaalta laskentaan. Tavoitearvioita täsmentävänä prosessina tietoketjulla on siten myös työmaan toimintaa parantava vaikutus.

MEPDG Work Plan Task No. 5: Characterization of Unbound Materials (Soils/Aggregates) for Mechanistic-Empirical Pavement Design Guide, 2009

The resilient modulus (MR) input parameters in the Mechanistic-Empirical Pavement Design Guide (MEPDG) program have a significant effect on the projected pavement performance. The MEPDG program uses three different levels of inputs depending on the desired level of accuracy. The primary objective of this research was to develop a laboratory testing program utilizing the Iowa DOT servo-hydraulic machine system for evaluating typical Iowa unbound materials and to establish a database of input values for MEPDG analysis. This was achieved by carrying out a detailed laboratory testing program designed in accordance with the AASHTO T307 resilient modulus test protocol using common Iowa unbound materials. The program included laboratory tests to characterize basic physical properties of the unbound materials, specimen preparation and repeated load triaxial tests to determine the resilient modulus. The MEPDG resilient modulus input parameter library for Iowa typical unbound pavement materials was established from the repeated load triaxial MR test results. This library includes the non-linear, stress-dependent resilient modulus model coefficients values for level 1 analysis, the unbound material properties values correlated to resilient modulus for level 2 analysis, and the typical resilient modulus values for level 3 analysis. The resilient modulus input parameters library can be utilized when designing low volume roads in the absence of any basic soil testing. Based on the results of this study, the use of level 2 analysis for MEPDG resilient modulus input is recommended since the repeated load triaxial test for level 1 analysis is complicated, time consuming, expensive, and requires sophisticated equipment and skilled operators.

MEPDG Work Plan Task No. 7: Existing Pavement Input Information for the Mechanistic-Empirical Pavement Design Guide, 2009

The objective of this study is to systematically evaluate the Iowa Department of Transportation’s (DOT’s) existing Pavement Management Information System (PMIS) with respect to the input information required for Mechanistic-Empirical Pavement Design Guide (MEPDG) rehabilitation analysis and design. To accomplish this objective, all of available PMIS data for interstate and primary roads in Iowa were retrieved from the Iowa DOT PMIS. The retrieved data were evaluated with respect to the input requirements and outputs for the latest version of the MEPDG software (version 1.0). The input parameters that are required for MEPDG HMA rehabilitation design, but currently unavailable in the Iowa DOT PMIS were identified. The differences in the specific measurement metrics used and their units for some of the pavement performance measures between the Iowa DOT PMIS and MEPDG were identified and discussed. Based on the results of this study, it is recommended that the Iowa DOT PMIS should be updated, if possible, to include the identified parameters that are currently unavailable, but are required for MEPDG rehabilitation design. Similarly, the measurement units of distress survey results in the Iowa DOT PMIS should be revised to correspond to those of MEPDG performance predictions. *******************Large File**************************

MEPDG Work Plan Task No. 8: Validation of Pavement Performance Curves for the Mechanistic-Empirical Pavement Design Guide, 2009

The objective of this research is to determine whether the nationally calibrated performance models used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) provide a reasonable prediction of actual field performance, and if the desired accuracy or correspondence exists between predicted and monitored performance for Iowa conditions. A comprehensive literature review was conducted to identify the MEPDG input parameters and the MEPDG verification/calibration process. Sensitivities of MEPDG input parameters to predictions were studied using different versions of the MEPDG software. Based on literature review and sensitivity analysis, a detailed verification procedure was developed. A total of sixteen different types of pavement sections across Iowa, not used for national calibration in NCHRP 1-47A, were selected. A database of MEPDG inputs and the actual pavement performance measures for the selected pavement sites were prepared for verification. The accuracy of the MEPDG performance models for Iowa conditions was statistically evaluated. The verification testing showed promising results in terms of MEPDG’s performance prediction accuracy for Iowa conditions. Recalibrating the MEPDG performance models for Iowa conditions is recommended to improve the accuracy of predictions. ****************** Large File**************************

Off-line simulation inspires insight: a neurodynamics approach to efficient robot task learning

There is currently an increasing demand for robots able to acquire the sequential organization of tasks from social learning interactions with ordinary people. Interactive learning-by-demonstration and communication is a promising research topic in current robotics research. However, the efficient acquisition of generalized task representations that allow the robot to adapt to different users and contexts is a major challenge. In this paper, we present a dynamic neural field (DNF) model that is inspired by the hypothesis that the nervous system uses the off-line re-activation of initial memory traces to incrementally incorporate new information into structured knowledge. To achieve this, the model combines fast activation-based learning to robustly represent sequential information from single task demonstrations with slower, weight-based learning during internal simulations to establish longer-term associations between neural populations representing individual subtasks. The efficiency of the learning process is tested in an assembly paradigm in which the humanoid robot ARoS learns to construct a toy vehicle from its parts. User demonstrations with different serial orders together with the correction of initial prediction errors allow the robot to acquire generalized task knowledge about possible serial orders and the longer term dependencies between subgoals in very few social learning interactions. This success is shown in a joint action scenario in which ARoS uses the newly acquired assembly plan to construct the toy together with a human partner.

Reducing the Risk: A Strategic Approach - The Report of the Task Force on Sudden Cardiac Death

Joint Commissioning Plan of the Health and Social Care Board and the Public Health Agency: 2010-2011

Legislation enacted on 1 April 2009 created a new Commissioning system with the establishment of a region-wide Health and Social Care Board, including 5 Local Commissioning Groups (LCGs), and a Public Health Agency. In line with Departmental direction and guidance the objectives of the new commissioning arrangements were to: - Approach the future delivery of Health and Social Care from a region-wide perspective focused on outcomes. - Ensure local sensitivity through the creation of five Local Commissioning Groups reflective of their areas. - Give appropriate weight to the public health agenda to ensure that commissioning reflects the drive to reduce health inequalities in our society and works in partnership with others to improve health and wellbeing. In this regard the legislation signalled a new way forward which would first be expressed in a Commissioning Plan for 2010/11 and beyond. This plan outlines how the Health and Social Care Board and the Public Health Agency are approaching that task. It is our aim that this plan is straightforward and written in a manner which will encourage public engagement and understanding. We wish to show clearly how the commissioning task is to be approached and to signal the decisions necessary to ensure the maintenance of a health and social care system in Northern Ireland which responds to the population it serves.

Report Against Drugs- an action plan to combat substance abuse in Longford.

The Forum for Longford was started in 1997 to provide a co-ordinated inter-agency approach to identify and help tackle social problems in Longford. A survey was carried out with 1,331 post-primary students to ascertain attitudes and behaviours towards alcohol, smoking and drug use. Of the pupils interviewed, 64% had taken an alcoholic drink at age 15 or younger; of these 73% had their first drink between the ages of 12 to 15. Of those that had experience of alcohol, 51% drank several times a week or daily. For smoking, 67% had smoked a cigarette; of these 8% smoked 5 or more daily. Of those that smoked, 47% began between the ages of 11 to 14. With regard to illegal drugs 27% had used cannabis, 20% had used inhalants, 10% hallucinogens, 9% amphetamines and 7.4% had used ecstasy. Following on form these findings, the report makes several recommendations, including the formation of a community task force, Garda/ neighbourhood watch response, schools prevention and information. Also among these key areas are the role of parents, the needs of young people and facilities for young people.This resource was contributed by The National Documentation Centre on Drug Use.

Tugan-Baranovsky on Socialism: From Utopia to the Economic Plan

Tugan-Baranovsky's ideas on socialism are reconstructed with an emphasis on the relation between political economy and utopia. Utopia enters the stage after the critique of capitalism, in the definition of the realm of possibilities in the world of ideas. With the help of ethics, the notion of ideal socialism, unreachable by definition, is defined in the sphere of utopia. Thus, the task of political economy is first to show which of these possible worlds are reachable in the real world, and second to choose the one that conforms better to ideal socialism: this is socialism in practice through the economic plan. Thus, far from considering utopia and science as contradictory, Tugan-Baranovsky saw them as complementary, and his socialism is the result of the dialogue he instituted between them.
