Developing Enterprise Dashboards
Wonchang Hur
Asian Journal of Information Technology , 2012,
Abstract: BPM system is an information system that is introduced to accelerate process cycle time through automation of repetitive organizational tasks. With growing importance of business process management, functionality of BPM systems is now extended to support the design, analysis and optimization of business processes. In particular, BPM brought in new applications related with managing business processes; Business Activity Monitoring (BAM) and Business Process Analysis (BPA). In this study, we raise four issues regarding the successful implementation of BAM and discuss what companies should do to address them. Specifically, we will focus on the identification of Key Performance Indicators (KPIs), mapping the KIPs to the BPM metrics. Designing the analysis methods and building digital dashboards. By linking BPM and BPA, BAM provides the visibility on what goes on with several major business processes and all the related information that will help managers make a well-informed, timely decision, so that it significantly accelerates the enterprise s reaction time.
La création d’un réseau de villes : circulations, pouvoirs et territoires
Maxime Huré
Métropoles , 2009,
Abstract: Cet article vise à questionner les effets d’un réseau de villes sur les politiques publiques urbaines à travers la naissance et l’évolution du Club des Villes Cyclables. Autrement dit, il s’agit d’ouvrir la boite noire d’un réseau de villes en analysant sa genèse, sa structure, ses enjeux, son activité, afin de mettre en lumière sa capacité à transformer les cadres de l’action publique urbaine. La description historique et institutionnelle du réseau montre l’importance des circulations dans chaque phase de développement du Club, à la fois à l’intérieur du réseau et sur les territoires urbains. Dans un premier temps, on observe ces circulations dès la genèse du réseau, à une période où le Club des Villes Cyclables souhaite constituer un lobby national du vélo urbain. Dans un deuxième temps, les circulations vont s’orienter vers l’échelle urbaine, à travers l’avènement d’un pouvoir d’agglomération technique et politique. Enfin, le réseau et ses circulations constituent, de plus en plus, un enjeu pour les territoires et les politiques publiques urbaines. What impact a cities network can have on urban public policies ? This article purpose is to enlighten this question through the birth, and evolution, of the Club des Villes Cyclables (Biking Cities Club). In other words to open the black box of a cities network and analyse its genesis, its structure, its stakes, its activity, and eventually show its ability to transform the framework of public urban policies. The historical and institutional description of the network underlines the importance of circulations in each stage of development of the Club, at once within the network and in the urban areas. These circulations can be observed from the genesis of the network, when the Club was willing to constitute a national lobby of urban biking. Later on, circulations will turn onto the urban scale, through the advent of a technical and political urban authority. Now, it appears that the network and its circulations constitute, more and more, a stake for the territories administration and the urban public policy.

Métropoles , 2011,
Abstract: L’ouvrage dirigé par Philippe Hamman est aujourd’hui incontournable pour ceux qui s’intéressent à la fabrique de l’urbain et aux questions de mobilité en ville. Il est incontournable au niveau de son objet d’étude. En effet, le tramway est de retour dans de nombreuses villes européennes. Il participe à transformer l’organisation spatiale, sociale ou encore institutionnelle des villes. Mais l’ouvrage est aussi incontournable car le Tramway dans la ville pose toute une série de question...
The Kuratowski covering conjecture for graphs of order < 10 for the nonorientable surfaces of genus 3 and 4
Suhkjin Hur
Mathematics , 2008,
Abstract: Kuratowski proved that a finite graph embeds in the plane if it does not contain a subdivision of either K_5 or K_{3,3}, called Kuratowski subgraphs. A conjectured generalization of this result to all nonorientable surfaces says that a finite minimal forbidden subgraph for the nonorientable surface of genus g can be written as the union of g+1 Kuratowski subgraphs such that the union of each pair of these fails to embed in the projective plane, the union of each triple of these fails to embed in the Klein bottle if g >= 2, and the union of each triple of these fails to embed in the torus if g >= 3. We show that this conjecture is true for all minimal forbidden subgraphs of order < 10 for the nonorientable surfaces of genus 3 and 4.
Density of Schr?dinger Titchmarsh-Weyl $m$ functions on Herglotz functions
Injo Hur
Mathematics , 2015,
Abstract: We will show that all Titchmarsh-Weyl $m$ functions corresponding to Schr\"odinger operators are dense in all Herglotz functions. To show this, we first discuss a topology on canonical systems which interacts with the uniform convergence of Herglotz functions on compact subsets of the upper half plane. We then characterize canonical systems which can be written in a Schr\"odinger (eigenvalue) equation and vice versa, which gives us an easy way to construct $m$ functions corresponding to Schr\"odinger equations in terms of canonical systems. Finally we approximate the canonical system whose $m$ function is a given Herglotz function by canonical systems which can be written in Schr\"odinger equations such that their $m$ functions converges to a given Herglotz function.
Committee Algorithm: An Easy Way to Construct Wavelet Filter Banks
Youngmi Hur
Mathematics , 2012,
Abstract: Given a lowpass filter, finding a dual lowpass filter is an essential step in constructing non-redundant wavelet filter banks. Obtaining dual lowpass filters is not an easy task. In this paper, we introduce a new method called committee algorithm that builds a dual filter straightforwardly from two easily-constructible lowpass filters. It allows to design a wide range of new wavelet filter banks. An example based on the family of Burt-Adelson's 1-D Laplacian filters is given.
Overexpression of OsMAPK2 Enhances Low Phosphate Tolerance in Rice and Arabidopsis thaliana  [PDF]
Yeon Jae Hur, Doh Hoon Kim
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.54059
Abstract:

The mitogen-activated protein kinase (MAPK) cascade is the most important mechanism in environmental responses and developmental processes in plants. The OsMAPK2 gene has been found to function in plant tolerance to diverse biotic/abiotic stresses. This paper presents evidence that OsMAPK2 (Oryza sativa MAP kinase gene 2) is responsive to Pi deficiency and involved in Pi homeostasis. We found that full-length expression of OsMAPK2 was up-regulated in both rice plants and cell culture in the absence of inorganic phosphate (Pi). The transgenic rice and Arabidopsis plants overexpressing OsMAPK2 showed affected root development and increased plant Pi content compared with wild-type plants. Overexpression of OsMAPK2 controlled the expression of several Pi starvation-responsive genes. Our results indicated that OsMAPK2 enables tolerance phosphate deficiency and is involved in Pi homeostasis.

In-Situ Synthesized Myoglobin Imprinted Poly(N-Isopropylacrylamide)/Silica Nanocomposite Gels by Using the Molecular Imprinting Method  [PDF]
Burcu Me?hur, Eylem Turan, Nursel Dilsiz
Advances in Materials Physics and Chemistry (AMPC) , 2014, DOI: 10.4236/ampc.2014.41001
Abstract:

Temperature sensitive imprinted poly(N-isopropylacrylamide) nanocomposite gels were syntheses via in-situ, free radical crosslinking polymerization of corresponding monomer in nano-sized silica and five different concentrations of myoglobin solution by using the molecular imprinting method. Mb adsorption from five different concentrations of Mb solutions was investigated by two types of nanocomposite gel systems prepared by non-imprinted and imprinted methods. Nanocomposite gels imprinted with Mb showed higher adsorption capacity and specificity for Mb than nanocomposite gels prepared by the usual procedure. The highest Mb adsorption was observed via the imprinted nanocomposite gels with 12.5% Mb. In addition, selectivity studies were also performed by using two reference molecules as fibrinogen and hemoglobin. The imprinted nanocomposite gels had higher adsorption capacity for Mb than the non-imprinted gels and also exhibited good selectivity for Mb and high adsorption rate depending on the number of Mb sized cavities.


Prediction of BOD, COD, and Total Nitrogen Concentrations in a Typical Urban River Using a Fluorescence Excitation-Emission Matrix with PARAFAC and UV Absorption Indices
Jin Hur,Jinwoo Cho
Sensors , 2012, DOI: 10.3390/s120100972
Abstract: The development of a real-time monitoring tool for the estimation of water quality is essential for efficient management of river pollution in urban areas. The Gap River in Korea is a typical urban river, which is affected by the effluent of a wastewater treatment plant (WWTP) and various anthropogenic activities. In this study, fluorescence excitation-emission matrices (EEM) with parallel factor analysis (PARAFAC) and UV absorption values at 220 nm and 254 nm were applied to evaluate the estimation capabilities for biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total nitrogen (TN) concentrations of the river samples. Three components were successfully identified by the PARAFAC modeling from the fluorescence EEM data, in which each fluorophore group represents microbial humic-like (C1), terrestrial humic-like organic substances (C2), and protein-like organic substances (C3), and UV absorption indices (UV220 and UV254), and the score values of the three PARAFAC components were selected as the estimation parameters for the nitrogen and the organic pollution of the river samples. Among the selected indices, UV220, C3 and C1 exhibited the highest correlation coefficients with BOD, COD, and TN concentrations, respectively. Multiple regression analysis using UV220 and C3 demonstrated the enhancement of the prediction capability for TN.
Wavelet-based identification of DNA focal genomic aberrations from single nucleotide polymorphism arrays
Youngmi Hur, Hyunju Lee
BMC Bioinformatics , 2011, DOI: 10.1186/1471-2105-12-146
Abstract: In this study, we introduce a novel method referred to as the wavelet-based identification of focal genomic aberrations (WIFA). The use of the wavelet analysis, because it is a multi-resolution approach, makes it possible to effectively identify focal genomic aberrations in broadly aberrant regions. The proposed method integrates multiple cancer samples so that it enables the detection of the consistent aberrations across multiple samples. We then apply this method to glioblastoma multiforme and lung cancer data sets from the SNP microarray platform. Through this process, we confirm the ability to detect previously known cancer related genes from both cancer types with high accuracy. Also, the application of this approach to a lung cancer data set identifies focal amplification regions that contain known oncogenes, though these regions are not reported using a recent CNAs detecting algorithm GISTIC: SMAD7 (chr18q21.1) and FGF10 (chr5p12).Our results suggest that WIFA can be used to reveal cancer related genes in various cancer data sets.With the recent advances of cancer studies at a molecular level, DNA copy number aberrations (CNAs) have been studied as important causes and consequences in the initiation, development, and progression of cancer. To date, many researchers have focused on the detection of chromosomal regions having amplifications and deletions using arrays of comparative genomic hybridization (CGH) data sets. These studies have generated valuable observations about cancer metastasis [1-7]. For example, it is now known that many oncogenes and tumor suppressor genes are located in regions of amplifications and deletions, and that chromosome regions with aberrations can be used to distinguish between cancer types. Also, new cancer related genes have been discovered. These advances have been accelerated by the development of computational methods and software [8-14]; segmentation and denoising methods such as circular binary segmentation (CBS) [8], wavel
