    SEISGAMA: A Free C# Based Seismic Data Processing Software Platform

    Seismic reflection is one of the most popular methods in geophysical prospecting. Nevertheless, obtaining high resolution and accurate results requires a sophisticated processing stage. There are many open-source seismic reflection data processing software programs available; however, they often use a high-level programming language that decreases its overall performance, lacks intuitive user-interfaces, and is limited to a small set of tasks. These shortcomings reveal the need to develop new software using a programming language that is natively supported by Windows® operating systems, which uses a relatively medium-level programming language (such as C#) and can be enhanced by an intuitive user interface. SEISGAMA was designed to address this need and employs a modular concept, where each processing group is combined into one module to ensure continuous and easy development and documentation. SEISGAMA can perform basic seismic reflection processes. This ability is very useful, especially for educational purposes or during a quality control process (in the acquisition stage). Those processes can be easily carried out by users via specific menus on SEISGAMA’s main user interface. SEISGAMA has been tested, and its results have been verified using available theoretical frameworks and by comparison to similar commercial software

    Clinical Educator and Student Perceptions of iPad™ Technology to Enhance Clinical Supervision: The Electronically-Facilitated Feedback Initiative (EFFI)

    Purpose: Growing demands placed upon healthcare systems require more health professionals to be trained. Clinical placement education is an integral component of health professional training, however accommodating increasing numbers of student placements is a challenge for health services. Personal digital assistants such as iPads™ may assist in delivery of clinical education, by facilitating transfer of knowledge and skills from clinical educators to health professional students, however such an initiative has not been formally investigated. The present study sought to explore perceptions of clinical educators and allied health students regarding the impact of an iPad™-based feedback delivery system on student reflection and learning. Methods: A pilot study was performed using iPads™ with specialised software to deliver electronic formative feedback to physiotherapy, occupational therapy and speech pathology students during clinical placements. Students and clinical educators completed a questionnaire exploring advantages and disadvantages of the technology. Results: Nine clinical educators and 14 students participated and completed the survey. Clinical educators largely (n=7, 78%) reported the electronic feedback system was easy to use and 67% (n=6) reported it improved the quality of feedback provided to students. Five (56%) clinical educators thought electronic feedback improved student performance. Most students (n=10, 71%) reported electronic feedback facilitated reflection upon performance, and 64% (n=9) reported improved performance as a result. Disadvantages included poor wireless internet access and software inefficiencies (n=7 [78%] clinical educators, n=7 [50%] students), and difficulties using iPads™ in settings requiring infection control (n=2 [22%] clinical educators). Conclusions: Clinical educators and students perceived electronic feedback as a positive adjunct to student learning on clinical placement, however technological and software interface factors need to be considered for implementation in some settings

    Bandpass filters play a significant role in wireless communication systems. Transmitted and received signals have to be filtered at a certain center frequency with a specific bandwidth. The major problem in design microstrip bandpass filter is to get a deeper and wider rejection bandwidth. In this thesis, a dual mode microstrip open loop resonators and filter is design to be operated at 5.7 GHz for wireless local area network (WLAN) using sonnet lite simulation software. Results have been analyzed in terms of reflection coefficient and transmission coefficient. The simulated filter performances are presented. The simulated result shows the performance of bandpass is better for resonator with contact feed compared with non contact feed

    Flexible data input layer architecture (FDILA) for quick-response decision making tools in volatile manufacturing systems

    Get PDF
    This paper proposes the foundation for a flexible data input management system as a vital part of a generic solution for quick-response decision making. Lack of a comprehensive data input layer between data acquisition and processing systems has been realized and thought of. The proposed FDILA is applicable to a wide variety of volatile manufacturing environments. It provides a generic platform that enables systems designers to define any number of data entry points and types regardless of their make and specifications in a standard fashion. This is achieved by providing a variable definition layer immediately on top of the data acquisition layer and before data pre-processing layer. For proof of concept, National Instruments’ Labview data acquisition software is used to simulate a typical shop floor data acquisition system. The extracted data can then be fed into a data mining module that builds cost modeling functions involving the plant’s Key Performance Factors
