EAI Implementation Project and Shakedown: An Exploratory Case Study

Enterprise Application Integration (EAI) is a pertinent approach to integrating core business processes and data processing in the organization. Based on a generic enterprise system experience cycle model and previous research on EAI and enterprise resource planning (ERP) projects, we propose an initial framework for the EAI implementation process. The framework is then applied in an exploratory case study of an EAI implementation project in a Norwegian energy group. As a result, we suggest a revised framework for the EAI implementation process. The revised framework identifies ten new factors based on the findings from the case study, which affect core business process integration by EAI,: two in connection to the chartering phase, six related to the project phase, and two for the shakedown phase of the enterprise system experience cycle. The framework provides guidance for practitioners when planning for EAI implementations.
Improvement of vector space information retrieval model based on supervised learning

This paper proposes and method to improve retrieval performance of the vector space model (VSM) by utilizing user-supplied information of those documents that are relevant to the query in question. In addition to the user's relevance feedback information, incorporated into the retrieval model, which is built by using a sequence of linear transformations, is information such as inter-document similarity values. Then, the high-dimensional and sparse vectors are reduced by SVD (Singular Value Decomposition) and transformed into the low-dimensional vector space, namely the space representing the latent semantic meanings of the words. The method was experimented on through two test collections, Medline collection and Cranfield collection. Improvement of average precision compared with LSI (Latent Semantic Indexing) model were 4.03% (Medline) and 24.87% (Cranfield) for the two training data sets, and 0.01% (Medline) and 4.89% (Cranfield) for the test data, respectively. The proposed method provides an approach that makes it possible to preserve the user-supplied relevance information for a long term in the system and to use the information later.
CrowdOp: Query Optimization for Declarative Crowdsourcing Systems

We study the query optimization problem in declarative crowdsourcing systems. Declarative crowdsourcing is designed to hide the complexities and relieve the user of the burden of dealing with the crowd. The user is only required to submit an SQL-like query and the system takes the responsibility of compiling the query, generating the execution plan and evaluating in the crowdsourcing marketplace. A given query can have many alternative execution plans and the difference in crowdsourcing cost between the best and the worst plans may be several orders of magnitude. Therefore, as in relational database systems, query optimization is important to crowdsourcing systems that provide declarative query interfaces. In this paper, we propose CROWDOP, a cost-based query optimization approach for declarative crowdsourcing systems. CROWDOP considers both cost and latency in query optimization objectives and generates query plans that provide a good balance between the cost and latency. We develop efficient algorithms in the CROWDOP for optimizing three types of queries: selection queries, join queries, and complex selection-join queries. We validate our approach via extensive experiments by simulation as well as with the real crowd on Amazon Mechanical Turk.
Fast Calculation of Read Field From Perpendicular Recording Medium Using Head Characteristic Matrix

A very fast calculation method of calculating the three-dimensional read head field from a perpendicular recording medium is presented using a head characteristic matrix K, and the medium charge with a spacing loss correction. The numerical integration in the evaluation of the matrix can be replaced with an infinite sum, speeding up the calculation significantly. The head characteristic matrix has a physical significance as the inverse matrix of the self-magnetostatic energy with a charge placed on the air bearing surface (ABS) of the read gap
A real convexity theorem for quasi-hamiltonian actions

The main result of this paper is a quasi-hamiltonian analogue of a special case of the O'Shea-Sjamaar convexity theorem for usual momentum maps. We denote by U a simply connected compact connected Lie group and we fix an involutive automorphism of maximal rank on this Lie group (such an automorphism always exists). We then denote by M a quasi-hamiltonian U-space and we prove that the image under the momentum map of the fixed-point set of a form-reversing compatible involution of M is a convex polytope, which is in fact equal to the full momentum polytope. This theorem was announced in arXiv:math/0609517v1. As an application, we obtain an example of lagrangian subspace in representation spaces of surface groups.
Efficient particle filter algorithm for ultrasonic sensor-based 2D range-only simultaneous localisation and mapping application

: Simultaneously localization and mapping (SLAM) is a fundamental topic in robotics and mobile computing communities. Owning to low cost and relatively accurate measurement, ultrasonic sensors are widely used in range only SLAM applications. But these applications are challenging to accurately obtain an initial position given to the SLAM algorithm, and robustly localize the targets in a highly dynamic environment. The traditional approaches to solve these problems are Extended Kalman Filter (EKF) and Particle Filter (PF) algorithms. However, EKF approach suffers from the data association problem and map consistency, PF approach is limited by the highly computational complexity. This paper addresses an improved particle filter algorithm to solve the ultrasonic sensor based 2D range-only simultaneously localization and mapping (SLAM) problem with relatively good accuracy and robustness. A technique called Map Adjustment is proposed to increase the accuracy and efficiency of the algorithm. Using Map Adjustment, the proposed particle filter algorithm can either achieve improved localisation accuracy, or maintain the same accuracy but lower computational complexity. The feasibility and robustness of this algorithm is shown by experiments. The results demonstrate that the proposed algorithm can provide relatively good accuracy and robustness for ultrasonic sensor based 2D range SLAM applications.
Humor as an abrasive or a lubricant in social situations: Martineau revisited

Abstract In Martineau’s seminal chapter on the social functions of humor, he postulated some of the ways in which disparagement humor shapes social behavior. This research paper discusses three research studies that compared the effects of other-deprecating humor and self-deprecating humor on the observer and examines how they relate to Martineau’s theory. In our research, we hypothesized that people who observe ridicule of others experience “jeer pressure. ” This inhibiting effect on behavior was expected to result in conformity to others’ opinions, fear about failing or standing out, and conventional thinking. In the first two studies, participants observed videotapes containing self-ridiculing humor, other-deprecating humor, or non-ridiculing/no humor. Participants then completed tasks assessing conforming, fear of failure, and creativity. Results of both studies showed that participants who observed ridicule of others were more conforming and more afraid of failing than participants who observed self-deprecating humor or the control condition. Study 3 examined the effects of ridicule of others versus self-deprecating humor on creativity using a more sophisticated creativity measure, and less caustic humor. Results supported the hypothesis that observing self-deprecating humor would result in higher levels of creativity compared to the other-ridicule condition. Implications of these findings for Martineau’s model are discussed.
NADH Dehydrogenase Defects Confer Isoniazid Resistance and Conditional Lethality in Mycobacterium smegmatis

ABSTRACT Isoniazid (INH) is a highly effective drug used in the treatment and prophylaxis of Mycobacterium tuberculosis infections. Resistance to INH in clinical isolates has been correlated with mutations in the inhA, katG, andahpC genes. In this report, we describe a new mechanism for INH resistance in Mycobacterium smegmatis. Mutations that reduce NADH dehydrogenase activity (Ndh; type II) cause multiple phenotypes, including (i) coresistance to INH and a related drug, ethionamide; (ii) thermosensitive lethality; and (iii) auxotrophy. These phenotypes are corrected by expression of one of two enzymes: NADH dehydrogenase and the NADH-dependent malate dehydrogenase of theM. tuberculosis complex. The genetic data presented here indicate that defects in NADH oxidation cause all of the mutant traits and that an increase in the NADH/NAD+ ratio confers INH resistance.
Production of Recombinant α-Galactosidases inThermus thermophilus

ABSTRACT A Thermus thermophilus selector strain for production of thermostable and thermoactive α-galactosidase was constructed. For this purpose, the native α-galactosidase gene (agaT) ofT. thermophilus TH125 was inactivated to prevent background activity. In our first attempt, insertional mutagenesis ofagaT by using a cassette carrying a kanamycin resistance gene led to bacterial inability to utilize melibiose (α-galactoside) and galactose as sole carbohydrate sources due to a polar effect of the insertional inactivation. A Gal+ phenotype was assumed to be essential for growth on melibiose. In a Gal−background, accumulation of galactose or its metabolite derivatives produced from melibiose hydrolysis could interfere with the growth of the host strain harboring recombinant α-galactosidase. Moreover, the AgaT− strain had to be Kms for establishment of the plasmids containing α-galactosidase genes and the kanamycin resistance marker. Therefore, a suitable selector strain (AgaT− Gal+ Kms) was generated by applying integration mutagenesis in combination with phenotypic selection. To produce heterologous α-galactosidase in T. thermophilus, the isogenes agaA and agaBof Bacillus stearothermophilus KVE36 were cloned into anEscherichia coli-Thermus shuttle vector. The region containing the E. coli plasmid sequence (pUC-derived vector) was deleted before transformation of T. thermophilus with the recombinant plasmids. As a result, transformation efficiency and plasmid stability were improved. However, growth on minimal agar medium containing melibiose was achieved only following random selection of the clones carrying a plasmid-based mutation that had promoted a higher copy number and greater stability of the plasmid.
Stability of wavelet frames with matrix dilations

Under certain assumptions we show that a wavelet frame {τ(A j ,b j,k )ψ} j,k∈Z :={|det A j | -1/2 ψ(A -1 j (x-b j,k ))} j,k∈Z in L 2 (R d ) remains a frame when the dilation matrices Aj and the translation parameters b j,k are perturbed. As a special case of our result, we obtain that if {τ(A j , A j Bn)ψ} j∈Z,n∈Z d is a frame for an expansive matrix A and an invertible matrix B, then {τ(A' j , A j Bλ n )ψ} j∈Z,n∈Z d is a frame if ||A -j A' j - I|| 2 ≤ e and ||λ n -n|| ∞ ≤ η for sufficiently small e, η > 0.
Dopamine Precursor Depletion Impairs Timing in Healthy Volunteers by Attenuating Activity in Putamen and Supplementary Motor Area

Neuropsychological investigations of patients with Parkinson's disease, schizophrenia, or attention deficit disorder converge with psychopharmacological studies in animals and healthy volunteers to implicate dopamine (DA) pathways in timing. In parallel, single-cell recording and functional neuroimaging studies have highlighted the importance of basal ganglia, prefrontal cortex, and supplementary motor area (SMA) for timing. In a placebo-controlled, within-subject design, we combined event-related functional magnetic resonance imaging with a DA manipulation (acute phenylalanine/tyrosine depletion; APTD) in healthy volunteers to pinpoint the neuroanatomical and functional substrates of the DA modulation of timing. Behaviorally, APTD selectively impaired accuracy of perceptual timing, with no effect on performance of a color-control task matched for difficulty, working memory (WM), and attentional demands. Neurally, APTD attenuated timing-specific activity in the putamen and SMA. Notably, APTD-induced decreases in brain activity were directly correlated to APTD-induced impairments in timing performance. Moreover, APTD modulated timing-specific activity selectively during initial storage of the sample duration, but had no effect during its subsequent retrieval or comparison to a probe. Our results do not simply reflect DA modulation of WM since the color task controlled for the WM updating process necessary for timing of durations in the seconds range. Moreover, preliminary evidence indicated APTD effects on putamen and SMA were greater for subsecond (540 ms) than suprasecond (1080 ms) durations, when WM demands would actually be lower. Instead, we show for the first time in healthy humans that DA manipulation perturbs timing by attenuating the activity in putamen and SMA that mediates initial storage of temporal information into WM.
Epigenetic DNA Methylation Mediating Octopus vulgaris Early Development: Effect of Essential Fatty Acids Enriched Diet

The common octopus, Octopus vulgaris, is a good candidate for aquaculture but a sustainable production is still unviable due to an almost total mortality during the paralarvae stage. DNA methylation regulates gene expression in the eukaryotic genome, and has been shown to exhibit plasticity throughout O. vulgaris life cycle, changing profiles from paralarvae to adult stages. This pattern of methylation could be sensitive to small alterations in nutritional and environmental conditions during the species early development, thus impacting on its health, growth and survival. In this sense, a full understanding of the epigenetic mechanisms operating during O. vulgaris development would contribute to optimizing the culture conditions for this species. Paralarvae of O. vulgaris were cultured over 28 days post-hatching (dph) using two different Artemia sp. based diets: control and a long chain polyunsaturated fatty acids (LC-PUFA) enriched diet. The effect of the diets on the paralarvae DNA global methylation was analyzed by Methyl-Sensitive Amplification Polymorphism (MSAP) and global 5-methylcytosine enzyme-linked immunosorbent assay (ELISA) approaches. The analysis of different methylation states over the time revealed a global demethylation phenomena occurring along O. vulgaris early development being directly driven by the age of the paralarvae. A gradual decline in methylated loci (hemimethylated, internal cytosine methylated, and hypermethylated) parallel to a progressive gain in non-methylated (NMT) loci toward the later sampling points was verified regardless of the diet provided and demonstrate a pre-established and well-defined demethylation program during its early development, involving a 20% of the MSAP loci. In addition, a differential behavior between diets was also observed at 20 dph, with a LC-PUFA supplementation effect over the methylation profiles. The present results show significant differences on the paralarvae methylation profiles during its development and a diet effect on these changes. It is characterized by a process of demethylation of the genome at the paralarvae stage and the influence of diet to favor this methylation loss.
Research Note: Public Administration Journal Prestige: A Time Series Analysis

Thomas Vocino and Robert H. Elliott This article examines journal prestige in the field of public administration, using data from three surveys, in 1975, 1978, and 1981, of the membership of the American Society for Public Administration. Two dimensions of intensity and extensity were analyzed. The intensity rating measured the strength of feeling toward a particular journal, while the extensity rating measured the breadth of recognition for a journal. The results of these surveys indicate that the top-rated journals maintained their positions overtime. The surveys also revealed differences between academics and practitioners in their perceptions of public administration and related journals.
Recognition, feelings of injustice and claim justification: a case study of deaf people's storytelling on the internet

This paper argues that Honneth's theory of recognition opens promising venues for exploring the role of emotion in politics, particularly when issues of injustice are at stake. While endorsing Honneth's view that ‘feelings of injustice’ are an important source for intelligibility of injustice, and that disadvantaged individuals need to build a ‘shared interpretative framework’ in struggles for recognition, this article contends that a more nuanced account of discursive justification is required to deal with dissent and moral disagreement. As a response to this problem, we suggest that Honneth's approach of subjective reaction to injury as violation of conditions to practical identity can be brought together with notions of discursive justification in the Habermasian fashion. Through an empirically based analysis – using storytelling of deaf people gathered in two virtual environments: (a) the website of the main Brazilian organization for deaf persons (FENEIS), and (b) Orkut, an online social network – this paper evinces that subjects not only articulate feelings of injustice or claims for recognition in everyday experience, but also usually engage in interpretation, judgment and justification of such claims. Results show that Honneth's theory of recognition, when articulated with a notion of discursive justification, can better equip scholars concerned with practices that aim to overcome injustice.
Chapter 6 2 D and 3 D Object Recognition and Positioning with Algebraic Invariants and Covariants

All Rights Reserved No part of this book may be reproduced in any form, by photostat, microfilm or any other means, without written permission from the publishers A catalogue record for this book is available from the British Library We describe part of our model-based approach to 3D rigid object recognition and positioning from range data: methods for fast classification and positioning of algebraic surfaces. Since we are primarily interested in recognizing and positioning rigid objects, we focus on methods invariant under Euclidean coordinate transformations, but we also include some extensions to the affine and projective cases. These cases are related to other recognition and positioning problems involving 2D or 3D curves. Our approach to model-based object recognition and positioning can be divided in four stages. In the first stage algebraic surfaces are fitted to regions of the data set. Then, in the second stage, a data base is searched for regions of known objects with algebraic surface approximations similar to those fitted to the data regions. In the third stage, a matching coordinate transformation is computed for each matching candidate extracted from the data base. These coordinate transformations are computed using explicit formulas, and constitute the estimated positions for the initially recognized object. These matches constitute initial hypotheses for the presence of the associated objects in the data regions. Finally, the hypotheses are globally tested to sort out inconsistencies. We start by reviewing some of our previous work on computationally attractive fitting of algebraic curves and surfaces. Then we introduce methods to solve the classification and positioning problems, the second and third stages of our approach. We base the fast data base search for similar algebraic surfaces, the classification problem, on comparing algebraic invariants. We compute the matching coordinate transformation between two surfaces with approximately the same invariants by associating an intrinsic frame of reference to every algebraic surface. This frame of reference, an object-based coordinate system, is a covariant function of the coefficients of the polynomial which defines the surface, and its relative location with respect to the surface is independent of the viewpoint. For a nonsingular quadratic surface, the eigenvalues of the matrix associated with the second degree terms of the defining polynomial are Euclidean invariants. The center of symmetry of the surface, and the eigenvectors of the same matrix define an intrinsic frame of reference. The methods introduced in this paper generalize these constructions to algebraic …
RNase A activity in Japanese quail oocytes

Summary The presence of RNase A activity was studied in vitro in homogenates of quail oocytes and early embryos using [3H]poly(U) as a substrate. The activity was measured by adsorption of the undegraded substrate onto DE-81 filter paper discs and by chromatographic separation on a Sephadex G-50 column. RNase A activity examined by these methods was almost undetectable in quail previtellogenic, vitellogenic and ovulated oocytes as well as in the embryos from laid eggs. It is estimated to be about 1.1 × 10−5 Kunitz units per ovulated oocyte. Higher activity starts to appear in gastrulating embryos. These findings are discussed in relation to other studies demonstrating the high stability of maternal RNA during early development, especially in growing oocytes.
Power and binary signal transmissions using couple of standard RFID antennas

The paper describes theoretical and mainly experimental evaluation of power transfer from a primary to a secondary coil and a transmission of an on-off signal back with an inductive coupling of pair of identical RFID antennas for 125 kHz band. Their function uses principles of RFID systems. The impact of conductive parts around the coils was also examined. The results were intended to design a simple telemetry system which transfers temperature data from a special rotor.
A wearable mixed reality with an on-board projector

One of the methods achieving mixed reality (MR) displays is the texture projection method using projectors. Another kind of emerging information environment is a wearable information device, which realizes ubiquitous computing. It is very promising to integrate these technologies. Using this kind of fusion system, two or more users can get the same MR environments without using HMD at the same moment. In this demonstration, we propose a wearable MR system with an on-board projector and introduce some applications with this system.
Multiplicity of Limit Cycle Attractors in Coupled Heteroclinic Cycles

A square lattice distribution of coupled oscillators that have heteroclinic cycle attractors is studied. In this system, we find a novel type of patterns that is spatially disordered and periodic in time. These patterns are limit cycle attractors in the ambient phase space (i.e. not chaotic), and there exsit many limit cycles, dividing the phase space into their basins. The patterns emerge from a local law concerning the difference between the phases of oscillators. The number of patterns grows exponentially as a function of the number of oscillators.
The enhancement of park current vectors technique for inverter fault detection

This paper work addresses the enhancement of this technique by associating it the polar coordinates as a proposed tool for a better detection and location of the faulty inverter switch. The proposed use of the polar coordinates tool not only allows the exact computation of both the magnitude and the phase angle values of the fault current vector allied to the faulty inverter IGBT but also enables to develop a simple graphical representation to facilitate the detection and location of the inverter fault by using a fault current vector representation instead of a trajectory representation as that in Park's vectors technique. To illustrate the merits and effectiveness of the enhanced detection Park's current technique, several simulation results are obtained and then validated by employing the experimental test-rig realized by the ‘diagnostic group’ in our LDEE laboratory.
