Dimension of Seamount Using Multibeam Echosounder in Bengkulu Waters

The purpose of this research was to determine the dimensions of seamount using echosuonder in Bengkulu waters. The survey was conducted by BPPT, LIPI, the Ministry of Energy and Mineral Resources, CGGVeritas, and the Institut de Physique du Globe (IPG) Paris in the southwest of the Sumatera island on 18-19 December 2010. Two acoustic instruments were used i.e., ELAC Seabeam 1050D with a frequency of 50 kHz and Simrad EM 12D with a frequency of 12 kHz. Data acquisition was obtained by using the hydrostar software in Baruna Jaya 3 and 4 research vessels. CARIS HIPS and SIPS6.1 softwares were used toprocess the data of bathymetry. Amplitude and backscatter data were obtained by data processing on the MBSystem. Data visualization in 3-D was performed using the Fladermaus 6.2 software (personal license of Djoko Hartoyo). Seamount form was assumed as a cone with an elliptical base to calculate the dimensions. The result showed an under water seamount of 320 Km from the southwest of Bengkulu city at -4°22'9.16''latitude and 99°25'01.47'' longitude. The seamount height was ± 3,968 meters and had two peak separated at ± 3,050 meters. Seamount peaks located at ± 1.270 meters below sea level. The major axis was ± 50,240 meters and the minor axis in this seamount was ± 5,644 meter

Knowledge Management Mediation Model of Higher Learning Institution Performance

There are many studies on Knowledge Management (KM) in different organizations however less investigation on university, especially teaching staff in terms of using KM to enhance their duties at the universities. Thus, this paper presents a study to examine the Critical Influential Factors of Knowledge Management and Innovation Management on UAE Universities Performance. The study adopted a quantitative approach where a questionnaire survey was carried out among academic staffs of UAE universities. A total of 330 respondents involved in this survey. The data gathered from the survey was used to develop the mediation model which comprises of innovation learning acts as mediator to the relationship between the five knowledge management variables and the university performance variable.  The model was developed and assessed in SmartPLS software. The mediation model comprises of direct effect relationship and mediation effect relationship. For direct effect relationship, it was found that two KM dimensions have a direct significant effect on universities’ performance, which are knowledge acquisition and knowledge application. And also, it indicates that there is a significant direct effect for innovation learning on university performance. For mediation effect, it was found that innovation learning on the relationship between KM dimensions (knowledge acquisition, knowledge storage, knowledge sharing, and knowledge application) and universities’ performance. The results from this modelling work, indicated that knowledge acquisition and knowledge sharing have a significant indirect effect on universities’ performance with partial mediation for knowledge acquisition and full mediation for knowledge sharing. The findings of this research could benefit academic and decision makers in terms of enhancing organization performance through KM. Also, innovation learning can be considered as a stimulant to KM in further enhancing the university organization performance

Three-dimensional echocardiography for left ventricular quantification: fundamental validation and clinical applications

One of the earliest applications of clinical echocardiography is evaluation of left ventricular (LV) function and size. Accurate, reproducible and quantitative evaluation of LV function and size is vital for diagnosis, treatment and prediction of prognosis of heart disease. Early three-dimensional (3D) echocardiographic techniques showed better reproducibility than two-dimensional (2D) echocardiography and narrower limits of agreement for assessment of LV function and size in comparison to reference methods, mostly cardiac magnetic resonance (CMR) imaging, but acquisition methods were cumbersome and a lack of user-friendly analysis software initially precluded widespread use. Through the advent of matrix transducers enabling real-time three-dimensional echocardiography (3DE) and improvements in analysis software featuring semi-automated volumetric analysis, 3D echocardiography evolved into a simple and fast imaging modality for everyday clinical use. 3DE provides the possibility to evaluate the entire LV in three spatial dimensions during the complete cardiac cycle, offering a more accurate and complete quantitative evaluation the LV. Improved efficiency in acquisition and analysis may provide clinicians with important diagnostic information within minutes. The current article reviews the methodology and application of 3DE for quantitative evaluation of the LV, provides the scientific evidence for its current clinical use, and discusses its current limitations and potential future directions

NON-INVASIVE BRAIN EEG ROBOT NAVIGATION FRAMEWORK BASED ON EMOTIV EPOC

A Brain computer interface (BCI) has introduced new dimensions and created a new era for creative applications for developers and researchers giving alternative communication channels for people suffering of motor disabilities. The motor system is currently the primary focus, where EEG signals are being obtained while the subject is imagining or performing a motor response. With the help of an EEG signals, navigating a robot or controlling a wheel chair has come from science fiction movies or stories to reality. The purpose of this study is to design a navigation framework for a robot or a wheel chair using the capabilities of the brain EEG using an online acquisition device in our case it’s Emotiv Epoc. The framework is based on SSVEP focusing on visual cortex EEG signal analysis, the methodology used to complete this application is agile software development which basically is based on iterative and incremental development providing a rapid and flexible product. The tools used to implement the framework are divided into two categories hardware and software as for the hardware EEG acquisition device is used to acquire EEG signals, a robot based on NXT logo is used to demonstrate the control capabilities of the framework, as for the software Emotiv SDK , Open vibe as a signal processing and visual studio to design the a GUI as a man in the middle for interfacing the EEG signal processing platform with the robot

The future of technology enhanced active learning – a roadmap

The notion of active learning refers to the active involvement of learner in the learning process, capturing ideas of learning-by-doing and the fact that active participation and knowledge construction leads to deeper and more sustained learning. Interactivity, in particular learnercontent interaction, is a central aspect of technology-enhanced active learning. In this roadmap, the pedagogical background is discussed, the essential dimensions of technology-enhanced active learning systems are outlined and the factors that are expected to influence these systems currently and in the future are identified. A central aim is to address this promising field from a best practices perspective, clarifying central issues and formulating an agenda for future developments in the form of a roadmap

Models of internationalisation: The New Zealand experience

This paper examines the models of internationalisation adopted by thirty firms from New Zealand. Analysis of the international model is based on five key dimensions: firm sector and size; international market scope; market entry and servicing strategies; and speed of internationalisation. Drivers and constraints to internationalisation are also considered in the analysis. Evaluation of these dimensions over time finds evidence of both traditional ‘stages’ and emergent ‘born (again) global’ models of internationalisation, and reveals that over one third of these firms experience dramatic change to their international activities and resources initiated by divestment or change of ownership. We refer to the alternative internationalisation trajectory adopted by these firms as the ‘transformational’ model of internationalisation. The paper makes a contribution to the extant literature by providing synthesis of the New Zealand internationalisation and by building on our understanding of how patterns of internationalisation from a small open economy are changing in response to global environmental pressures

Communication issues in requirements elicitation: A content analysis of stakeholder experiences

The gathering of stakeholder requirements comprises an early, but continuous and highly critical stage in system development. This phase in development is subject to a large degree of error, influenced by key factors rooted in communication problems. This pilot study builds upon an existing theory-based categorisation of these problems through presentation of a four-dimensional framework on communication. Its structure is validated through a content analysis of interview data, from which themes emerge, that can be assigned to the dimensional categories, highlighting any problematic areas. The paper concludes with a discussion on the utilisation of the framework for requirements elicitation exercises

EChO Payload electronics architecture and SW design

EChO is a three-modules (VNIR, SWIR, MWIR), highly integrated spectrometer, covering the wavelength range from 0.55 $\mu$m, to 11.0 $\mu$m. The baseline design includes the goal wavelength extension to 0.4 $\mu$m while an optional LWIR module extends the range to the goal wavelength of 16.0 $\mu$m. An Instrument Control Unit (ICU) is foreseen as the main electronic subsystem interfacing the spacecraft and collecting data from all the payload spectrometers modules. ICU is in charge of two main tasks: the overall payload control (Instrument Control Function) and the housekeepings and scientific data digital processing (Data Processing Function), including the lossless compression prior to store the science data to the Solid State Mass Memory of the Spacecraft. These two main tasks are accomplished thanks to the Payload On Board Software (P-OBSW) running on the ICU CPUs.Comment: Experimental Astronomy - EChO Special Issue 201
