Control of mobile manipulators for power assist systems

We present a control algorithm for mobile power assist systems. Most mobile power assist systems have a heavy mobile base to prevent easy tumbling. So continual movement of the base during operations causes high energy consumption and gives the high risk of human injury. Furthermore, the slow dynamics of the base limits the frequency bandwidth of the whole system. Thus we propose a cooperation control method of the mobile base and manipulator to remove the unnecessary movement of the base. In our scheme, the mobile base does not move until the center of gravity (C.G.) of the system goes outside the safety region. When C.G. reaches the boundary of the safety region, the base starts to move to recover the manipulator's initial configuration. By varying the parameters of a human impedance controller, the operator is warned by a force feedback that C.G. is on the marginal safety region. Assigning a nonlinear mass-damper-spring impedance to the tip of the manipulator, our scheme is implemented. The experimental results are presented to demonstrate the efficacy of the control algorithm.
An Evaluation of the Human Relations Workshops and Training Programs.

The human relations task force of Milwaukee Area Technical College (MATC) sponsors a workshop series to improve human relations/productivity at the college. A practicum study evaluated the workshops by using the postworkshop training evaluation forms completed by workshop participants from 1990 to 1994. Data from a literature review were also incorporated into the evaluation. Of the 202 past wbrkshop participants surveyed, 145 (727.) believed that the workshops trained them to discuss and resolve differences with college objectives and 182 (907.) credited the workshops with helping them treat people with more understanding. Although most participants believed that the workshops increased their understanding of coworkers who are ethnically and culturally different from them, only 32%-467. stated that the workshops improved their understanding of coworkers with disabilities, and 22 (11%) stated that they still did not understand their disabled coworkers after having attended the workshops. It was recommended that the workshops be continued but that their curriculum be modified to include modules on dealing with disabled individuals and that future workshops be offered to part-time faculty and staff.

SRDF: Korean Open Information Extraction using Singleton Property

In this paper, we propose a new Korean Open Information Extraction system so-called SRDF. The SRDF system has been designed to effectively extract reified triples from Korean natural language texts based on the use of singleton property and other natural language processing techniques such as part-ofspeech tagging and chunking. The SRDF system is the Open Information Extraction system that enables extracting a multiple number of triples from a single sentence via reification.

System-level metrics for hardware/software architectural mapping

The current trend in Embedded Systems (ES) design is moving towards the integration of increasingly complex applications on a single chip, while having to meet strict market demands which force to face always shortening design times. In general, the ideal design methodology shall support the exploration of the highest possible number of alternatives (in terms of HW-SW architectures) starting in the early design stages as this will prevent costly correction efforts in the deployment phase. The present paper will propose a new methodology for tackling the design exploration problem, with the aim of providing a solution in terms of optimal partitioning with respect of the overall system performance.
From Tutoring to Cognitive Rehabilitation: Exploiting CBM to Support Memory Training

Constraint-Based Modeling (CBM) is an effective student modeling approach which has been used successfully in a wide range of instructional domains. Within the Intelligent Computer Tutoring Group (ICTG), we have developed numerous constraint-based tutors and demonstrated their effectiveness in real courses. In this paper, however, we discuss how we use CBM in the area of cognitive rehabilitation after stroke. Our computer-based treatment is aimed at improving prospective memory. Participants are first trained on how to use visual imagery and then practice in a Virtual Reality (VR) environment. We present how we use constraints to track the participant’s progress when performing tasks in the VR environment.
Prospects of the Theory of Prospects

The article offers a version of further development of the prospects theory fundamentals in the aspect of institutional forms creation and development model. D. Kahneman and A. Tverski’s “dimensionality of decisions and judgements” is taken as the starting point of institutional dimension formation. The ontological vector is added to the cognitive one in order to form the space. The mental and physical dichotomy is considered within the Helical Institutional Development Scheme framework.
Executive functions are associated with gait and balance in community-living elderly people.

BACKGROUND Cognition influences gait and balance in elderly people. Executive functions seem to play a key role in this mechanism. Previous studies used only a single test to probe executive functions, and outcome measures were restricted to gait variables. We extend this prior work by examining the association between two different executive functions and measures of both gait and balance, with and without two different cognitive dual tasks. METHODS This is a cross-sectional study with randomly selected community-living elderly people. Executive functions were tested with the Trail Making Test Parts A and B and the Stroop Color Word Test; memory with Cambridge Neuropsychological Test Automated Battery (CANTAB) subtests. Patients walked without and with two dual tasks (subtracting serial sevens and animal naming). Main outcomes focused on gait (velocity, stride length, and stride time variability), measured on an electronic walkway, and balance, measured as trunk movements during walking. Associations were assessed with multiple regression models. RESULTS One hundred elderly people, with a mean age 80.6 years (range 75-93 years) participated. Both dual tasks decreased gait velocity and increased variability and trunk sway. Executive functions were associated with only stride length variability and mediolateral trunk sway during performance of animal naming as the dual task. Memory was not associated with the gait and balance variables. CONCLUSIONS In community-living elderly people, executive functions are associated with gait and balance impairment during a challenging dual-task condition that also depends on executive integrity. Next steps will be to explore the value of executive functions in defining fall-risk profiles and in fall-prevention interventions for frail patients.
Simulation Study of Workfunction Variability in MOSFETs with Polycrystalline Metal Gates

The polycrystalline nature of the metal gate and the corresponding non-uniformity in the gate workfunction results in statistical variability in MOSFETs with high-! /metal gate stacks. Here the impact of the workfunction variation (WFV) associated with different gate grain orientations on the threshold voltage variation in a test bed 35 nm nMOSFETs is studied in details using full scale 3D numerical simulation. The workfunction-induced variability is compared with the variability introduced by other traditional sources of statistical variability including random discrete dopants (RDD) and line edge roughness (LER).

Relationship between the cAMP levels in leukocytes and the cytokine balance in patients surviving gram negative bacterial pneumonia

Lipopolysaccharide-stimulated leukocytes secrete proinflammatory cytokines including tumor necrosis factor-α and interleukin-12. Over-activation of host defense systems may result in severe tissue damage and requires regulation. Granulocyte colony-stimulating factor and interleukin-10 are candidate cytokines for inducing tolerance to lipopolysaccharide re-stimulation. We compared cytokines secreted by lipopolysaccharide-stimulated blood cells from patients who had survived gram negative bacterial pneumonia (Pseudomonas aeruginosa, Escherichia coli or Proteus mirabilis, n = 26) and age-matched healthy volunteers (n = 18). Interleukin-12p70 and tumor necrosis factor-α expression was significantly lower in patients (p = 0.0039 and p<0.001) compared to healthy controls, while granulocyte colony-stimulating factor production was markedly higher in patients (p<0.001). Levels of interleukin-10 were comparable. Granulocyte colony-stimulating factor expression was inversely correlated with interleukin-12p70 (R = −0.71, p<0.001) and tumor necrosis factor-α (R = −0.64, p<0.001) expression; interleukin-10 showed no significant correlation. In unstimulated leukocytes from patients, cAMP levels were significantly raised (p = 0.020) and were correlated inversely with interleukin-12p70 levels (R = −0.81, p<0.001) and directly with granulocyte colony-stimulating factor (R = 0.72, p = 0.0020), matrix metalloproteinase-9 (R = 0.67, p = 0.0067) and interleukin-10 (R = 0.54, p = 0.039) levels. Our results demonstrate that granulocyte colony-stimulating factor production by lipopolysaccharide-stimulated leukocytes is a useful indicator of tolerance induction in surviving pneumonia patients and that measuring cAMP in freshly isolated leukocytes may also be clinically significant.
Intracluster light in the Virgo cluster: large scale distribution

Aims. The intracluster light (ICL) is a faint diffuse stellar component of clusters made of stars that are not bound to individual galaxies. We have carried out a large scale study of this component in the nearby Virgo cluster. Methods. The diffuse light is traced using planetary nebulae (PNe). The surveyed areas were observed with a narrow-band filter centered on the [OIII]λ5007 A emission line redshifted to the Virgo cluster distance (the on-band image), and a broad-band filter (the off-band image). For some fields, additional narrow band imaging data corresponding to the Hα emission were also obtained. The PNe are detected in the on-band image due to their strong emission in the [OIII]λ5007 A line, but disappear in the off-band image. The contribution of Ly-α emitters at z = 3.14 are corrected statistically using blank field surveys, when the Hα image at the field position is not available. Results. We have surveyed a total area of 3.3 square degrees in the Virgo cluster with eleven fields located at different radial distances. Those fields located at smaller radii than 80 arcmin from the cluster center contain most of the detected diffuse light. In this central region of the cluster, the ICL has a surface brightness in the range μB = 28.8−30 mag arsec −2 , it is not uniformly distributed, and represents about 7% of the total galaxy light in this area. At distances larger than 80 arcmin the ICL is confined to single fields and individual sub-structures, e.g. in the sub-clump B, the M 60/M 59 group. For several fields at 2 and 3 degrees from the Virgo cluster center we set only upper limits. Conclusions. These results indicate that the ICL is not homogeneously distributed in the Virgo core, and it is concentrated in the high density regions of the Virgo cluster, e.g. the cluster core and other sub-structures. Outside these regions, the ICL is confined within areas of ∼100 kpc in size, where tidal effects may be at work. These observational results link the formation of the ICL with the formation history of the most luminous cluster galaxies.
EARQ: Energy Aware Routing for Real-Time and Reliable Communication in Wireless Industrial Sensor Networks

Wireless industrial sensor networks are wireless sensor networks which have been adapted to industrial applications. Most techniques for wireless sensor networks can be applied to wireless industrial sensor networks. However, for industrial applications of wireless industrial sensor networks, new requirements such as real-time, reliable delivery need to be considered. In this paper, we propose EARQ, which is a novel routing protocol for wireless industrial sensor networks. It provides real-time, reliable delivery of a packet, while considering energy awareness. In EARQ, a node estimates the energy cost, delay and reliability of a path to the sink node, based only on information from neighboring nodes. Then, it calculates the probability of selecting a path, using the estimates. When packet forwarding is required, it randomly selects the next node. A path with lower energy cost is likely to be selected, because the probability is inversely proportional to the energy cost to the sink node. To achieve real-time delivery, only paths that may deliver a packet in time are selected. To achieve reliability, it may send a redundant packet via an alternate path, but only if it is a source of a packet. Experimental results show that EARQ is suitable for industrial applications, due to its capability for energy efficient, real-time, reliable communications.
The Elusive Quest for Inclusive Growth: Growth, Poverty, and Inequality in Asia

This paper assesses how pro-poor and inclusive Asia’s recent growth has been, and what factors have been driving these outcomes. It finds that while poverty has fallen across the region over the last two decades, inequality has increased, dampening the impact of growth on poverty reduction. As a result, relative to other emerging and developing regions and to Asia’s own past, the recent period of growth has been both less inclusive and less pro-poor. Our analysis suggests a number of policies that could help redress these trends and broaden the benefits of growth in Asia. These include fiscal policies to increase spending on health, education, and social safetynets; labor market reforms to boost the labor share of total income; and reforms to make financial systems more inclusive.
How Behavior Trees generalize the Teleo-Reactive paradigm and And-Or-Trees

Behavior Trees (BTs) is a way of organizing the switching structure of a control system, that was originally developed in the computer gaming industry but is now also being used in robotics. The Teleo-Reactive programs (TRs) is a highly cited reactive hierarchical robot control approach suggested by Nilsson and And-Or-Trees are trees used for heuristic problems solving. In this paper, we show that BTs generalize TRs as well as And-Or-Trees, even though the two concepts are quite different. And-Or-Trees are trees of conditions, and we show that they transform into a feedback execution plan when written as a BT. TRs are hierarchical control structures, and we show how every TR can be written as a BT. Furthermore, we show that so-called Universal TRs, guaranteeing that the goal will be reached, are a special case of so-called Finite Time Successful BTs. This implies that many designs and theoretical results developed for TRs can be applied to BTs.
Crisis maps validation and user requirements: an experience in SAFER project

The European Commission is putting a relevant effort in developing earth observation based Emergency Response Services (ERS), through the Global Monitoring for Environment and Security initiative and several FP7 projects, such as SAFER (Services and Applications For Emergency Response). The validation process developed in SAFER aims at measuring the effectiveness, reliability and usability of the ERS against users’ requirements. The JRC (Joint Research Centre of the European Commission) and the BBK (German Federal Office of Civil Protection and Disaster Assistance) are working together bridging the different perspectives. After a two year SAFER experience, a diversity of products are published whereas the user’s requirements and feedback are still incomplete. The definition of validation criteria is therefore a challenge. In some cases the independent validation raised problems that did not represent critical issues for the users, in some others it gave technical reference for the final users evaluation. A variety of users, with differing needs, is involved. Their feedback has been collected through a survey: the results indicate that some users are highly satisfied with the service and products whereas others point to some major issues. For example in some cases the phenomena in the maps were far from what had been found in the emergency area, and in some other cases the final users did not use or used partially the provided information during the response operations. This paper presents the JRC and BBK experience in SAFER project about validation against user requirements and users’ satisfaction. * Corresponding author.
THE EMBEDDEDNESS OF ENTREPRENEURSHIP EDUCATION IN THE CURRICULA OF NON-BUSINESS UNIVERSITY PROGRAMMES: PRELIMINARY EVIDENCE FROM SOUTH AFRICAN UNIVERSITIES OF TECHNOLOGY

The total early stage entrepreneurial activity (TEA ) in South Africa is said to be extremely low compared to those of other sub-Saharan countrie s. This is despite the concerted efforts of the government to establish, develop and nurture entrepreneurship at all levels, especially among the youths. This calls for concern given the current state of the economy and the challenges faced by South Africa’s future g eneration. This paper is anchored on two theoretical frameworks to substantiate our argu ment for the inclusion of entrepreneurship education in the curricula of non- business programmes at universities of technology. The theoretical frameworks are the cont ingency organizational theory and the magnet versus radiant model. The study adopted an exploratory cross sectional research
High-Cloud Horizontal Inhomogeneity and Solar Albedo Bias

High ice cloud horizontal inhomogeneity is examined using optical depth retrievals from four midlatitude datasets. Three datasets include ice cloud microphysical profiles derived from millimeter cloud radar at the Southern Great Plains Atmospheric Radiation Measurement site in Oklahoma. A fourth dataset combines lidar and midinfrared radiometry (LIRAD), and is from the Facility for Atmospheric Remote Sensing at the University of Utah, Salt Lake City, Utah. Plane-parallel homogeneous (PPH) calculations of domain-averaged solar albedo for these four datasets are compared to independent column approximation (ICA) results. A solar albedo bias up to 25% is found over a low reflective surface at a high solar zenith angle. A spherical solar albedo bias as high as 11% is shown. The gamma-weighted radiative transfer (GWRT) scheme is shown to be an effective correction for the solar albedo bias suitable for GCM applications. The GWRT result was, in all cases, within 1‐2 Wm 22 of the ICA outgoing solar flux. The GWRT requires a parameterization of the standard deviation of cloud optical depth. It is suggested that the domain-averaged cloud optical depth and ice water path together can be used in a parameterization to account for 80% of the standard deviation in optical depth.
Semantic Matching Between Job Offers and Job Search Requests

An orthodontic appliance is provided which applies a pulsating force to the tooth to be moved, rather than a continuous force as in the case with the prior art devices. The invention is predicated on the concept that when pulsating forces are applied to the tooth, there is little or no hyalinization and consequently more cellular activity, giving rise to more oesteoclastic activity for bone resorption and more oesteoblastic activity for bone opposition. Moreover, the pulsational effect of the tooth on the adjacent periodontal membrane and bone tends to loosen their fibrous structure, and helps the tooth to find a path of least resistance through the bone.
An integrated virtual environment for visual-based reaching

An interactive application to test different visuo-motor interactions is presented. The long term goal is to obtain a perceptual agent capable of achieving a full 3D awareness for interaction control/planning in the peripersonal space by using the interplay between vision and motion. We have developed an integrated virtual reality environment that implements robotic reaching tasks based on stereo visual cues. Stereo processing adopts a generalized phase-based algorithm to handle the 2D disparities present in active stereo vision system in order to achieve high accuracy.
The IMF’s Stand-by Arrangements and the Economic Downturn in Eastern Europe: The Cases of Hungary, Latvia, and Ukraine

This paper looks at three countries that have been hard-hit by the world economic recession, and have turned to the IMF for assistance: Hungary, Latvia, and Ukraine. In all of these countries, it would appear that there were more sensible responses to the crisis that would reduce the loss of employment and output, cuts in social services, and political instability that have resulted from the downturn. Instead, the governments’ responses to the downturn as well as IMF conditions for assistance have caused additional harm.
Relatedness measures between conferences in computer science: a preliminary study based on DBLP

A large percentage of the research in computer science is published in conferences and workshops. We propose three methods which compute a "relatedness score" for conferences relative to a pivot conference, usually a top rated conference. We experiment with the DBLP bibliography to show that our relatedness ranking can be used to help understand the basis of conference reputation ratings, determine what conferences are related to an area and the classification of conferences into areas.
