Electronic documentation management refers to the imaging documentation and document management technologies. In order to build a good electronic documentation management system, it is important to create a workflow for the process and follow up system (it also called e-tracking). This paper describes the workflow and follow up system in directorate of scholarship and cultural relations in Iraq. E-tracking provides a monitoring service on different section in this directorate. This research developed a workflow by discussing with main manager and some staff in this directorate. This study has two steps: first one is to make a follow up system (management system) in the Iraqi directorate of scholarship and cultural relations, which is the roadmap for creating a follow up system for this directorate in the future. Final step is the follow up system of this directorate. This tracking system provides more control on the work by keeping an eye on the staff in this directorate, and also it decreases the work process within short time. Finally, the main aim of this system to reduce the effort of doing the work and save the time. © 2014 IEEE.

WordNet Domains (WND) is a lexical resource where synsets have been semi-automatically annotated with one or more domain labels from a set of 170 hierarchically organized domains. The uses of WND include the power to reduce the polysemy degree of the words, grouping those senses that belong to the same domain. This paper presents a novel automatic method to propagate domain information through WordNet. We compare both labellings (the original and the new one) allowing us to detect anomalies in the original WND labels. We also compare the quality of both resources (the original labelling and the new one) in a common Word Sense Disambiguation task. The results show that the new labelling clearly outperform the original one by a large margin. © 2012 Springer-Verlag.

MONTREAL, QUEBEC--(Marketwired - Dec. 19, 2016) - Aurvista Gold Corporation ("Aurvista" or the "Company") (TSX VENTURE:AVA)(OTC PINK:ARVSF)(FRANKFURT:AV2) is pleased to announce the start of a ground UTEM-5 Geophysical Survey (the "Survey") on the Douay Gold Project ("Douay"). Lamontagne Geophysics Ltd., of Kingston, Ontario, will initiate and complete the Survey over the next month on the most significant bedrock conductors at Douay: Anomalies "E", "F" and "G". Results will be made available by mid-Q1-2017. As previously reported by Aurvista in August 2016, the Company had completed a 1,421 line-km airborne helicopter magnetic, time-domain electromagnetic ("TDEM") and radiometric survey. The TDEM survey outlined 7 strong near surface conductive bedrock anomalies ("A" to "G"), all associated to the strongest EM-INPUT™ anomalies, 4 in proximity to the Casa Berardi Deformation Zone ("A" to "D"), NW of the Adam Creek Gold Deposit (the "Deposit"), and 3 in proximity to, and surrounding the 'South Porphyry" ("E" to "G"), S of the Deposit. Characteristics of Anomalies "E", "F" and "G" are summarized as follows: Anomaly "E" is the most significant since it is located in proximity to the gold bearing "Main Porphyry", the "South Porphyry" and the "Adam-Porphyry". There are chlorite-sulphide bearing "feeder pipes" nearby as observed in drill holes DO-92-24 and DO-11-34, typically found in association with massive sulphide mineralization, yet to be found at Douay. The historical drill holes DY-99-04, 05 and 06, 46878-0, 46899-9 and 0, 64487-0, 468880-0 and D-92-32 skimmed the anomaly by drilling above or holes were too short, but explained the conductive source as graphite. There is no graphite in the re-logged drill core. Anomalies "F" and "G" are larger in size but are believed, based on nearby re-logged drill core from the Phase 1 program, to be related to sulphide mineralization. However, laminar graphite was observed in centimeter-wide shear zones in core from the Anomaly "F" area. UTEM is an acronym for University of Toronto Electro-Magnetic system. It is a wide-band time-domain electromagnetic ("EM") system, which uses a large fixed transmitter loop and a moving receiver. It is different from other EM systems in that it can detect good EM conductors in the presence of poorer ones. The UTEM system measures the EM response while the transmitter field is changing (on-time measurements). UTEM sees both the freely decaying and directly driven part of the magnetic field. It is this second aspect that makes UTEM unique and so important in detecting and characterizing extremely conductive deposits such as massive sulphides. The field procedure consists of first laying out a large loop of a single strand insulated wire and energizing it with a current from a transmitter powered by a motor generator. The loop is either square or rectangular shaped with sides between 300 meters and 4,000 meters long. At Douay, the loops are 1,500 meters by 1,200 meters. Survey lines are generally oriented perpendicular to one side of the loop and surveying can be performed both inside and outside the loop. At Douay, readings are off loop as the targets are thought to be steeply dipping. The UTEM receiver gathers and records a number of channels of data at each station simultaneously reading all three components. The higher number channels correspond to high frequency, while the lower number channels correspond to low frequency. Therefore, poor or weak conductors will respond on higher channels. Progressively better conductors will give responses on progressively lower number channels. Massive and highly conducting sulphides or graphite will produce a response on all channels, with graphite showing more linear anomalies and massive sulphides being more compact. Aurvista Gold Corporation is a junior gold exploration and development Company with 130,689,121 shares outstanding trading on the TSX Venture Exchange in Canada, the Frankfurt Stock Exchange and OTC Pink Sheets in the US. Aurvista's only asset is the Douay Gold Project, consisting of a 100% owned interest in 250 contiguous claims totaling 133.1 km2, plus a 90% interest in 5 contiguous claims totaling 0.2 km2 and a 75% interest (25% held by SOQUEM) in 32 contiguous claims totaling 11.9 km2. In total there are 287 claims covering 145.3 km2 located along a 20 km segment of the Casa Berardi Deformation Zone in the prolific Abitibi Belt of northern Quebec. Douay is located 40 km SW of the Matagami Zinc Base Metal Camp and 150 km N of the Val-d'Or-Malartic Gold Camp (both in Quebec). In August, 2012, Aurvista updated the Mineral Resources estimates that included all drilling completed to the end of March 2012, for the now termed Adam Creek Gold Deposit. The deposit contains Mineral Resources estimates of 2.7 million tonnes of Indicated Resources at 2.76 g/t gold for 238,000 ounces (above a 0.3 g/t gold cut-off grade) or 2.5 million tonnes grading 2.98 g/t gold (at a 0.5 g/t gold cut-off grade) for 235,500 ounces. There were additional Inferred Resources of 115 million tonnes at 0.75 g/t gold for 2.75 million ounces (above a 0.3 g/t gold cut-off grade) or 62 million tonnes grading 1.06 g/t gold for 2.1 million ounces (above a 0.5 g/t cut-off grade). Following the closing of the $6 million financing on November 15, 2016, the Company finalized the priority targeting of the initial 3,700 meters in 7 drill holes of the Phase 2 Drilling Program. The first targets were selected on the basis of their potential to prove up new and additional gold mineralization in the Douay West - Northwest - Adam Porphyry - Central Zones sector. Drilling and the UTEM Survey results will be incorporated in the 3-D geological model to add more drilling targets with the objective of increasing the overall quantity and quality of mineral resources of Douay.

The smart phone has become essential part of personal and business life across all age boundaries. The smart phone usage can potentially play a significant role in assisting the elderly in many ways especially in terms of maintaining social relationship, providing a sense of safety and accessibility. However, elderly seems to be the neglected user group in the design of recent smart phone interface and the penetration of the technology to the elderly are very low. Hence this paper attempt to report issues that are related to why this particular group of user aged 40 years old and above was influenced to own the smart phones and the data gathering was done specifically in Malaysia context. This research used an interview and survey instrument to obtain the data from the intended target group of user whom are using smart phones. The result indicates three main factors that influence the respondents to own their smart phone which is family encouragement, the use of mobile internet and social networking. © 2005 - 2014 JATIT & LLS.

A comparative study on vector controlled Permanent Magnet Synchronous Motor (PMSM) drive with Proportional-Integral (PI) speed controller for long cable implementation. As reported by previous research, long cable caused an over voltage problem at motor terminal and could be double from the pulse output voltage at inverter terminal. However, this paper addresses another important application issue, namely increased losses in the motor drive system caused degrade and instability of the speed performances when long cable lengths are required. Two different length cables which are 1 meter and 10 meter connected from dSPACE to PMSM and the results are compared and evaluated. A DS1103DSP embedded with the Real-Time Interface (RTI) provided by dSPACE, hysteresis current controller scheme and PI control has been developed for a high performance control for PMSM drives The robustness of different length of cable over load disturbance, step response and change at command setting with inertia variations are studied. © 2005 - 2012 JATIT & LLS.

This review paper describes the implementation process for STEPNCFBUoA. Its software environment is first explained. ST-Developer is the central software tool that is responsible for converting EXPRESS schema to Java classes. FBDK is the tool used for developing the function blocks editor, raw material user interface, machining set-up data interface, and machine tool database. The two examples in the ISO 14649-11 standard are used as the main test parts. The paper provides a detailed account of STEP-NC data processing, Graphic user interface (GUI) and local manufacturing databases, for example, raw material, set-up, machine tool, and cutting tool databases. Machining simulation is validated through physical machining. This is done through machining a number of parts with varying data. The simulation graphic user interface is simple and wire-frame based, but sufficiently illustrates the tool-path information as well as showing the machine tool's limits, and set-up orientations. © (2014) Trans Tech Publications, Switzerland.

Having a significance vulnerability classification is important in developing a strong confidence in choosing the damaging cases associated with testing problems. The accurate classification helps to explain the belonging of vulnerability. The current research failed to empirically describe these matters, due to the absence of generic classification for testing and assessment. The aim of this paper is to fulfil this gap by enhancing the vulnerability classification meant for a secured software testing. This enhancement, which benefited from the issues of users view point and abstraction level, is later implemented in a vulnerability report database to determine the pattern of vulnerability relationship. As a result, the patterns, which support the traceability aspect, exposed the ability to be mapped with requirement elicitation through use case notation and served as a practical tool to demonstrate the impact and priority in performing the appropriate secure software testing. © 2014 WIT Press.

The dual motor drives fed by a single inverter are purposely designed to reduce size and cost with respect to single motor drives fed by a single inverter. This paper presents the speed responses behavior of Dual Permanent Magnet Synchronous Motor (PMSM) driven by Mean and Differential Torque Control technique. The drive is simulated by using Hysteresis Current Controller. MATLAB/Simulink is chosen as the simulation tools. The performance of speed, current and torque responses for Dual Motor PMSM fed by a single inverter is presented. The applied technique shows satisfactory speed regulation for a wide range of speed either with load, no load or variation of load. © 2005 - 2011 JATIT & LLS. All rights reserved.
