Using IT tool to manage expert knowledge: Case study: KMORE implementation in TELKOM R&D center

As the biggest incumbent communication service provider (CSP) in Indonesia, TELKOM has a big challenge in competing with its competitor to win the competition in the dynamic market. Since the knowledge or intellectual is the key driver to win the competition, it is a big challenge for TELKOM on how to manage its knowledge, so it can give the highest business value. Innovation process in TELKOM is intensively take place in it sun it called R&D Center. This R &D Center is very unique, since most of its production machine is human brain. So its success is mainly depends on its human resource technical and business skill, level of creativity, innovation and motivation. Those should be blend and reside in its human resources, so that they can become competitive and produce highly marketable innovative products and solutions. To help knowledge management implementation, an IT Tool is significantly a must. This paper aims at describing KMORE application and its best practices as IT tool to support knowledge management implementation in TELKOM R&D Center.
SPLICE: Sub‐second diffusion‐sensitive MR imaging using a modified fast spin‐echo acquisition mode

Recent human studies for measuring of the apparent diffusion coefficient in tissue by magnetic resonance imaging have been conducted by time‐consuming standard spin‐echo acquisition sequences and phase correction with navigator echoes. Diffusion‐weighted echo‐planar sequences have been shown to be rapid alternatives for brain imaging. Both methods show inherent disadvantages in applications on thoracic or abdominal sites. A new approach combining single‐shot diffusion‐weighted imaging with a modified fast spin‐echo acquisition mode is reported here. The modification is necessary, because normal fast spin‐echo acquisition requires a particular phase relation between the magnetization and the refocusing pulses. Unfortunately, this phase relation is not provided after diffusion sensitive preparation. Therefore, the split echo acquisition mode was developed and is shown to be insensitive to the phase of the magnetization. The advantages of both fast spin‐echo acquisition and diffusion weighting can be combined in the SPLICE sequence (split aqcuisition of fast spin‐echo signals for diffusion imaging). The applicability of the new technique is shown by series of sub‐second diffusion‐weighted images from different parts of the body.
Lost in Translation: Reflecting on a Model to Reduce Translation and Interpretation Bias

Aim: This paper reflects on the language and translation challenges faced and interventions used whilst undertaking cross-cultural public health research in Nepal using translators. Background: The growth in cross-cultural studies and international research highlights the use of translators and the associated challenges for researchers with regard to cultural and linguistic issues when collecting data in one language and analysing and reporting in another. The specific challenges when using translators are frequently overlooked in the research literature and translators and the interpretation processes omitted from the research methodology and/or discussion. Methods: The experiences and challenges for an English-speaking nurse researcher working with a team of translators in a cross-cultural study on the sexual and reproductive health (SRH) of young people in Nepal, in 2006, is explored in this paper. The paper employs a case study approach. The Study: Data were collected over four weeks observing the settings, and the SRH knowledge and practices of participants in two villages in Kathmandu Valley were identified using a questionnaire, which was administered as a structured interview, and from the nurse researcher’s field notes. This provided information on the translation and interpretation events. Stages in the research process where error could occur are identified in the researchers model and the interventions taken to minimise these are discussed which clarify perspectives and opinions when researching in the field. Findings and Conclusion: Reflecting on translation and interpretation challenges during the data collection process in a language which the nurse researcher does not speak, can help reduce (or avoid) potential mistakes and error. The paper reflects on a model of translation processes which emerged during fieldwork which helps understand what events happened and what actions were taken to obtain the most accurate data. Using a model such as this for cross cultural fieldwork may be useful for both novice and established researchers.
Cyclic mechanical behaviour of granular soils: experimental results and constitutive modelling

The paper illustrates cyclic torsional shear experimental test results obtained on dry dense Toyoura sand specimens. The dependency of the soil specimen mechanical response on loading amplitude is discussed. Both equivalent/tangent elastic shear stiffness and damping ratio are evaluated by using different definitions. Their evolution with the number of cycles performed at different loading amplitudes is analysed: the irreversibility of the material mechanical response is discussed. Experimental data are then reproduced by means of a non associated multiple mechanism elastoviscoplastic constitutive model characterised by two generalized plastic mechanisms: one viscoplastic and one inner kinematic plastic which is capable of capturing the material mechanical response even when small cyclic tests are performed.
Reusability-based quality framework for software components

Component based software engineering (CBSE) is a pivotal approach to software development since it helps to give much aspired benefits like reusability, on-time delivery, high quality at low cost to software companies. Therefore, individual software components must be selected with care as these are crucial to the success of the CBSE approach. The selection of a highly reusable and high-quality component is still a herculean task since stakeholders with varying expectations are involved in the software engineering process. This paper presents a reusability based quality model, which is suited to the identification and evaluation of software components. Three major stakeholders are recognized, which are important in the selection of a software component as well as to the development of software. In the proposed model, only those quality properties are incorporated that are preferred by stakeholders and necessary to increase the reuse of software components.
Resilience of civil infrastructure systems: literature review for improved asset management

Infrastructure resilience has drawn significant attention in recent years, partly because the occurrence of low-probability and high-consequence disruptive events like Hurricane Katrina, the Indonesian tsunami, terrorism attack in New York, and others. Since civil infrastructure systems support society welfare and viability, continuous infrastructural operation is critical. Along protection approaches, resilience concepts support achievement of near-continuous infrastructure operation. A variety of frameworks, models, and tools exist for advancing infrastructure resilience research. Nevertheless, translation of resilience concepts into practical methodologies for informing civil infrastructure operation and management remains challenging. This paper presents a state-of-the-art literature review on civil infrastructure resilience, particularly water distribution systems, enabling practical applications of infrastructure resilience towards improved system management. The literature review has two stages, quantitative and qualitative. Infrastructure resilience is defined to provide a foundation for operationalisation of infrastructure resilience concepts, enabling the inclusion of practical resilience considerations in formal management systems such as infrastructure asset management systems.
A low-voltage CMOS low-dropout regulator with novel capacitor-multiplier frequency compensation

This paper presents a low-voltage, low-quiescent current, low-dropout voltage regulator (LDO) with a novel capacitor-multiplier frequency compensation technique. The proposed compensation strategy can make the LDO stable under the entire load-current range without relying on an ESR zero. By eliminating cascode structure or buffer stage, the proposed LDO facilitates low voltage operation. Moreover, the capacitor-multiplier circuit reduces the on-chip compensation capacitor greatly and can be effectively realized without extra current budget. Implemented in a 0.18-mum CMOS technology, the LDO is able to provide 200 mA load current with 160 mV dropout voltage while consuming only 20 muA ground current. With a 1 muF output capacitor, the load-transient output variation is 17 mV through maximum current step changes. The on-chip compensation capacitor is reduced to 1 pF.
The PhysioFlow Thoracic Impedancemeter Is Not Valid for the Measurements of Cardiac Hemodynamic Parameters in Chronic Anemic Patients

The aim of the present study was to test the validity of the transthoracic electrical bioimpedance method PhysioFlow® to measure stroke volume in patients with chronic anemia. Stroke volume index (SVI), as well as cardiac index (CI) obtained by transthoracic electrical bioimpedance method and doppler echocardiography were compared in healthy subjects (n = 25) and patients with chronic anemia (i.e. mainly with sickle cell anemia; n = 32), at rest. While doppler echocardiography was able to detect difference in SVI between the two populations, the Physioflow® failed to detect any difference. Bland & Altman analyses have demonstrated no interchangeability between the two methods to assess CI and SVI in anemic patients and healthy subjects. While doppler echocardiography displayed a good concordance for SVI results with those obtained in the literature for anemic patients, the Physioflow® did not. Finally, in contrast to doppler echocardiography: 1) the CI obtained with the Physioflow® was not correlated with the hemoglobin level and 2) the stroke volume determined by the Physioflow® was highly influenced by body surface area. In conclusion, our findings indicate that the Physioflow® device is inaccurate for the measurement of SVI and CI in patients with chronic anemia and has a poor accuracy for the measurement of these parameters in African healthy subjects.
Capacity limit of cognitive radio with dynamic frequency hopping under imperfect spectrum sensing

In this paper, we investigate the capacity limit of a single secondary user (SU) communication link in a cognitive radio system. An SU transmitter establishes the communication with its receiver by dynamically hopping in a frequency spectrum pool, and by sensing the spectrum to exploit the temporal communication opportunities. We characterize the performance of sensing by false-alarm and miss-detection probabilities. Firstly, focusing on a high channel input power region, we develop an upper bound on the SU capacity by assuming a Gaussian distributed output. A lower bound on the SU capacity is also derived using a Gaussian input. We then show that the lower bound closely approaches the upper bound at a high channel input power level. This means that the Gaussian input is nearly optimal in this case. Furthermore, we characterize the impact of primary user activities and sensing performance on the SU capacity by developing a closed-form tight approximation. Secondly, paying attention to a low channel input power region, we propose a genie-aided upper bound and a lower bound using the Gaussian input. By comparing these two bounds, a closed-form approximation to the capacity is developed and the near optimality of the Gaussian input is demonstrated. Finally, numerical results are provided to complement the theoretical discussion.
To Cause Or Not To Cause: Cross-Lingual Semantic Matching for Paraphrase Modelling

This paper presents a manual pilot study in cross-linguistic analysis at the predicateargument level. Looking at translation pairs differing in their parts of speech, we find that predicate-argument structure abstracts somewhat from morphosyntactic language idiosyncrasies, but there is still considerable variation in the distribution of semantic material over predicates. We propose an algorithm for automatically identifying matching predicateargument structures (frame paraphrases). The resulting data allows an analysis of semantic differences e.g. in the expression of different degrees of causality.
Family-based performance measurement

Most contemporary programs are customizable. They provide many features that give rise to millions of program variants. Determining which feature selection yields an optimal performance is challenging, because of the exponential number of variants. Predicting the performance of a variant based on previous measurements proved successful, but induces a trade-off between the measurement effort and prediction accuracy. We propose the alternative approach of family-based performance measurement, to reduce the number of measurements required for identifying feature interactions and for obtaining accurate predictions. The key idea is to create a variant simulator (by translating compile-time variability to run-time variability) that can simulate the behavior of all program variants. We use it to measure performance of individual methods, trace methods to features, and infer feature interactions based on the call graph. We evaluate our approach by means of five feature-oriented programs. On average, we achieve accuracy of 98%, with only a single measurement per customizable program. Observations show that our approach opens avenues of future research in different domains, such an feature-interaction detection and testing.
Pentacyclic Triterpenoids from the Medicinal Herb, Centella asiatica (L.) Urban

Centella asiatica accumulates large quantities of pentacyclic triterpenoid saponins, collectively known as centelloids. These terpenoids include asiaticoside, centelloside, madecassoside, brahmoside, brahminoside, thankuniside, sceffoleoside, centellose, asiatic-, brahmic-, centellic- and madecassic acids. The triterpene saponins are common secondary plant metabolites and are synthesized via the isoprenoid pathway to produce a hydrophobic triterpenoid structure (aglycone) containing a hydrophilic sugar chain (glycone). The biological activity of saponins has been attributed to these characteristics. In planta, the Centella triterpenoids can be regarded as phytoanticipins due to their antimicrobial activities and protective role against attempted pathogen infections. Preparations of C. asiatica are used in traditional and alternative medicine due to the wide spectrum of pharmacological activities associated with these secondary metabolites. Here, the biosynthesis of the centelloid triterpenoids is reviewed; the range of metabolites found in C. asiatica, together with their known biological activities and the chemotype variation in the production of these metabolites due to growth conditions are summarized. These plant-derived pharmacologically active compounds have complex structures, making chemical synthesis an economically uncompetitive option. Production of secondary metabolites by cultured cells provides a particularly important benefit to manipulate and improve the production of desired compounds; thus biotechnological approaches to increase the concentrations of the metabolites are discussed.
Microstrip-Fed Circularly Polarized Square-Ring Patch Antenna for GPS Applications

A novel coupling technique for circularly polarized square-ring patch antenna is developed and discussed. The circular polarization (CP) radiation of the square-ring patch antenna is achieved by a simple microstrip feed line through the coupling of a square patch on the same plane of the antenna. Proper positioning of the coupling square patch excites two orthogonal resonant modes with 90deg phase difference, and a pure circular polarization is obtained. The dielectric material is a square block of ceramic with a permittivity of 58 and that reduces the size of the antenna. The prototype has been designed, fabricated and found to have an impedance bandwidth of 1.1% and a 3-dB axial-ratio bandwidth of about 0.03% at GPS frequency of 1573 MHz. The characteristics of the proposed antenna have been studied by simulation software HFSS and experiments. The measured and simulated results are in good agreement.

Self-* Storage: Brick-based Storage with Automated Administration (CMU-CS-03-178)

This white paper describes a new project exploring the design and implementation of “self-* storage systems:” self-organizing, self-configuring, self-tuning, self-healing, self-managing systems of storage bricks. Borrowing organizational ideas from corporate structure and automation technologies from AI and control systems, we hope to dramatically reduce the administrative burden currently faced by data center administrators. Further, compositions of lower cost components can be utilized, with available resources collectively used to achieve high levels of reliability, availability, and performance.
Effects of Different Adjuvants in the Context of Intramuscular and Intranasal Routes on Humoral and Cellular Immune Responses Induced by Detergent-Split A/H3N2 Influenza Vaccines in Mice

ABSTRACT Influenza A/H3N2 viruses have caused the most severe epidemics since 1968 despite current immunization programs with inactivated vaccines. We undertook a side-by-side preclinical evaluation of different adjuvants (Alum, AS03, and Protollin) and routes of administration (intramuscular [i.m.] and intranasal [i.n.]) for assessing their effect on the immunogenicity and cross-reactivity of inactivated split vaccines (A/H3N2/New York/55/2004). Humoral and T cell-mediated immune responses against the homologous virus and a heterologous drifted strain (A/H3N2/Wisconsin/67/2005) were measured in BALB/c mice at 2, 6, and 19 weeks postboost. The AS03- and Alum-adjuvanted i.m. vaccines induced at least an 8-fold increase over the nonadjuvanted vaccine in functional antibody titers against both the homotypic and heterotypic strains and low IgG2a and high IgG1 levels, suggesting a mixed Th1/Th2 response with a Th2 trend. The Protollin-adjuvanted i.n. vaccine induced the lowest IgG1/IgG2a ratio, which is indicative of a mixed Th1/Th2-type profile with a Th1 trend. This adjuvanted vaccine was the only vaccine to stimulate a mucosal IgA response. Whatever the timing after the boost, both hemagglutination inhibition (HAI) and microneutralization (MN) titers were higher with the AS03-adjuvanted i.m. vaccine than with the protollin-adjuvanted i.n. vaccine. Finally, the Alum-adjuvanted i.m. vaccine and the lower-dose Protollin-adjuvanted i.n. vaccine elicited significantly higher CD4+ Th1 and Th2 responses and more gamma interferon (IFN-γ)-producing CD8+ T cells than the nonadjuvanted vaccine. Our data indicate that the adjuvanted vaccines tested in this study can elicit stronger, more persistent, and broader immune responses against A/H3N2 strains than nonadjuvanted inactivated influenza vaccines.
Northeastward motion of nighttime medium‐scale traveling ionospheric disturbances at middle latitudes observed by an airglow imager

[1] Nighttime medium-scale traveling ionospheric disturbances (MSTIDs) observed in 630-nm airglow images at middle latitudes are known to have a predominantly northwest-southeast phase surface and to move southwestward in the Northern Hemisphere of Earth. However, the mechanisms of MSTID generation and their systematic southwestward motion have not been clarified. In this paper, we report the “northeastward” motion of the MSTIDs observed at Paratunka, Far East Russia (52.97°N, 158.25°E), using an all-sky 630-nm airglow imager at 2000–2300 LT on 19 August 2007. The MSTIDs moved first southwestward but then back northeastward in the northern part of the images. The northeastward motion of the MSTIDs took place coincident with a F layer height decrease observed by an ionosonde at Paratunka. The F layer height decrease was also confirmed by an enhancement of the 630-nm airglow intensity, which seemed to propagate from northeast to southwest. This fact suggests that the F layer height decrease was caused by poleward wind enhancement rather than westward electric field. These observations imply that the F layer height decrease or the poleward thermospheric wind has some role in the northeastward turning of the MSTID propagation direction.
Automated planning for collaborative UAV systems

Mission planning for collaborative Unmanned Aircraft Systems (UAS:s) is a complex topic which involves trade-offs between the degree of centralization or decentralization required, the degree of abstraction in which plans are generated, and the degree to which such plans are distributed among participating UAS:s. In realistic environments such as those found in natural and man-made catastrophes where emergency services personnel are involved, a certain degree of centralization and abstraction is necessary in order for those in charge to understand and eventually sign off on potential plans. It is also quite often the case that unconstrained distribution of actions is inconsistent with the loosely coupled interactions and dependencies which arise between collaborating systems. In this article, we present a new planning algorithm for collaborative UAS:s based on combining ideas from forward chaining planning with partial-order planning leading to a new hybrid partial order forward-chaining (POFC) framework which meets the requirements on centralization, abstraction and distribution we find in realistic emergency services settings.
