The graphic user interface of the AudioGraph Recorder (PC version) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

With the popularity of the use of computers and the development of the Internet, many multimedia-authoring systems have been developed for computer-based teaching and learning. This is playing an increasingly important role in education. One authoring system is the AudioGraph project developed at Massey university of N.Z., which have been developed for recording audio-graphic presentation material for publication in an html reference environment, i.e. "on the web". One of the tools in the AudioGraph project is the AudioGraph Recorder, which is a Macintosh application for recording or authoring web-based multimedia presentations. Due to the success of the publication of the AudioGraph application and the need of PC users, an AudioGraph Recorder for the PCs is required. This project is about the porting of the AudioGraph Recorder from the Macintosh platform to the PC platform. First this project report explains the functionality of the AudioGraph Recoder (the Macintosh version), especially how the end users interact with the interface of the AudioGraph Recorder, and the corresponding state changes of the controls in the interface. Then the report compares the development tools used in both platforms. The Macintosh version of the AudioGraph Recorder has been developed with the PowerPlant framework in CodeWarrior environment, but the PC version uses MFC framework in Visual C++ 6.0. This report also describes in detail how the interface of the AudioGraph Recorder application was constructed with the MFC, and implementation of some functionality of the application. At the same time some internals of the MFC framework are discussed

EE Student Workstation Lab Status Report December, 1988

The Maclab project in the Spring of 1988 demonstrated that providing a Macintosh workstation environment to some sections of EE 267 (Digital Logic Design Laboratory) was both useful and feasible on a small scale. The goals of the EE Student Workstation project this past Summer and Fall were: A. To provide all sections of EE 267 (approximately 200 students) with a Macintosh workstation environment for the simulation of digital logic circuits and for the preparation of reports. B. Tb provide a useful Macintosh workstation environment to other Electrical Engineering students. C. To transfer responsibility for operational aspects of the Macintosh Workstatiori facilities to the Engineering Computer Network (ECN). The opening of the new Materials Science and Electrical Engineering (MSEE) building in August 1988 provided space to establish the EE Student Workstation Laboratory; The facility occupies two rooms (186 and 190) within the terminal room complex of the MSEE building. The lab is equipped with 40 Macintosh Plus personal computers networked together via AppleTalk and bridged to the Engineering Computer Network (ECN). A Macintosh Il with two 40 Megabyte hard drives is used as an applications server. Application serving can also be handled by one of ECN\u27s Sun Server Machines. Using Aufs (Apple-Unix file serving) software, students can access and store Macintosh files on their regular ECN UNIX accounts. Each room is equipped with a dot matrix and a laser printer for hard copy output. An instructor\u27s machine is equipped with an LCD display and overhead projector so that large screen class demonstrations can be given. The goal of expanding use of MacIntosh student workstations to all EE267 students was successful. In addition, software purchases were made to make the facility a useful and productive environment for other EE students. Significant progress has been made in integrating this type of facility into normal ECN operations. This report describes the operation and status of the EE Student Workstation Labs as of the end of the 1988 Fall semester. Recommendations based upon the experience gained during the semester are made

A CLIPS-based tool for aircraft pilot-vehicle interface design

The Pilot-Vehicle Interface of modern aircraft is the cognitive, sensory, and psychomotor link between the pilot, the avionics modules, and all other systems on board the aircraft. To assist pilot-vehicle interface designers, a C Language Integrated Production System (CLIPS) based tool was developed that allows design information to be stored in a table that can be modified by rules representing design knowledge. Developed for the Apple Macintosh, the tool allows users without any CLIPS programming experience to form simple rules using a point and click interface

Randomized crossover trial comparing cervical spine motion during tracheal intubation with a Macintosh laryngoscope versus a C-MAC D-blade videolaryngoscope in a simulated immobilized cervical spine

Abstract Background Maintaining cervical immobilization is essential during tracheal intubation in patients with unstable cervical spines. When using the Macintosh laryngoscope for intubation in patients with cervical immobilization, substantial neck extension is required for visualization of the glottis. However, the C-MAC D-Blade videolaryngoscope may require less neck extension due to its acute angulation. We hypothesized that C-MAC D-Blade videolaryngoscopic intubation would result in less cervical spine movement than Macintosh laryngoscopic intubation. We compared the effects of C-MAC D-Blade videolaryngoscopic intubation and Macintosh laryngoscopic intubation in terms of cervical spine motion during intubation in patients with simulated cervical immobilization. Methods In this randomized crossover study, the cervical spine angle was measured at the occiput–C1, C1–C2, and C2–C5 segments before and during tracheal intubation with either a C-MAC D-Blade videolaryngoscope or Macintosh laryngoscope in 20 patients, with application of a neck collar for simulated cervical immobilization. Cervical spine motion was defined as the change in angle measured before and during tracheal intubation. Results The cervical spine motion at the occiput–C1 segment was measured at 12.1 ± 4.2° and 6.8 ± 5.0° during Macintosh laryngoscopic and C-MAC D-blade videolaryngoscopic intubation, respectively, corresponding to a 44% reduction in cervical spine motion when using the latter device (mean difference, − 5.3; 98.33% CI: − 8.8 to − 1.8; p = 0.001). However, there was no significant difference between the two intubation devices at the C1–C2 segment (− 0.6; 98.33% CI: − 3.4 to 2.2; p = 0.639) or C2–C5 segment (0.2; 98.33% CI: − 6.0 to 6.4; p = 0.929). Conclusions The C-MAC D-Blade videolaryngoscope causes less upper cervical spine motion than the Macintosh laryngoscope during tracheal intubation of patients with simulated cervical immobilization. Trial registration This study was registered at ClinicalTrials.gov on June 26, 2018 ( NCT03567902 )

Comparing McGRATH® MAC, C-MAC®, and Macintosh Laryngoscopes Operated by Medical Students: A Randomized, Crossover, Manikin Study

We hypothesized that the McGRATH MAC would decrease the time of intubation compared to C-MAC for novices. Thirty-nine medical students who had used the Macintosh blade to intubate a manikin fewer than 3 times were recruited. The participants performed sequential intubations on the manikin in two simulated settings that included a normal airway and a difficult airway (tongue edema). The intubation time, success rate of intubation, Cormack-Lehane grade at laryngoscopy, and difficulty using the device were recorded. Each participant was asked to identify the device that was most useful. The intubation time decreased significantly and by a similar amount to the McGRATH MAC and C-MAC compared to the Macintosh blade (P < 0.001 and P = 0.017, resp.). In the difficult airway, the intubation times were similar among the three devices. The McGRATH MAC and C-MAC significantly increased the success rate of intubation, improved the Cormack-Lehane grade, and decreased the difficulty score compared to the Macintosh blade in both airway settings. The majority of participants selected the McGRATH MAC as the most useful device. The McGRATH MAC and C-MAC may offer similar benefits for intubation compared to the Macintosh blade in normal and difficult airway situations.ope

Comparison of the effectiveness between c-mac d-blade and glidescope for tracheal intubation in patients with cervical spine immobilisation simulated by a semi-rigid collar

Objective: Among the technique for cervical spine immobilisation is putting on semi-rigid collar but it renders difficult tracheal intubation. In this study, our aim is to compare the effectiveness of two available videolaryngoscopes meant for difficult intubation C-MAC D-Blade (DB) and GlideScope (GS). In terms of improvement of glottic view, time for successful intubation and haemodynamic changes on patients with a semi-rigid cervical collar. Methodology: This was a prospective, single-blinded, controlled trial with eighty patients scheduled for elective surgery under general anaesthesia. They were selected during premedication round with ASA I-II without any features of difficult intubation. They were randomized equally into two groups, 40 patients each group according to the studied videolaryngoscopes. After induction of general anaesthesia the semi-rigid collar was placed and repeated laryngoscopy was performed using conventional direct Macintosh laryngoscope, C-MAC D-Blade or GlideScope according to randomisation groups before patients were intubated with GliteRite styleted endotracheal tube. Glottic view was scored using Cormack Lehane (CL) and Percentage of Glottic Opening (POGO) scores with Macintoch and respective videolaryngoscope and time for successful intubation were recorded. All patients were successfully intubated by one operator experienced in the use of each laryngoscopes. Patient’s blood pressure, MAP and heart rate were recorded as a baseline value, post intubation at 1, 3, 5 and 10 minutes. Results: Both videolaryngoscopes showed significantly better Cormack Lehane grade and POGO scores than direct laryngoscope by Macintosh (DL). Majority of glottic view by DL were CL III and IV in both group. It was significantly reduced with the C-MAC D-Blade (DB), 40 patients (100%) had CL I and GlideScope (GS), 30 patients (75%) and 9 patients (22.5%), had CL I and CL II respectively. Only 1 patient had CL III by GlideScope and none had CL IV. Time to best achievable glottic view was significantly better in DB group with mean (SD) 11.68 (3.24) seconds vs 14.69 (5.59) seconds in GS group, p<0.001. Successful intubation time was significantly shorter in DB 37.57 (10.81) seconds than GS 53.03 (14.45) seconds, p<0.001. There were no significant changes in the baseline hemodynamic parameters (SBP, DBP, MAP and HR) and after intubation except reduced SBP in GS at 5 minutes post intubation. However there were significantly reduced SBP, DBP and MAP in both DB and GS between pre-intubation and post intubation. Hence no difference on incidence of complication in both groups. Conclusions: Compared to direct Macintosh laryngoscopy, both C-MAC D-Blade and GlideScope resulted in an improved view of glottic opening with successful intubation in all patients. The C-MAC D-Blade showed superior performance than GlideScope in this group of patient with semi-rigid collar applied during intubation on improvement of CL score and shorter duration for intubation. DB may serve as device of choice for intubation in difficult situation but further study needed to confirm these findings

Characterizing 51 Eri b from 1-5 μ\mum: a partly-cloudy exoplanet

We present spectro-photometry spanning 1-5 $\mu$m of 51 Eridani b, a 2-10 M$_\text{Jup}$ planet discovered by the Gemini Planet Imager Exoplanet Survey. In this study, we present new $K1$ (1.90-2.19 $\mu$m) and $K2$ (2.10-2.40 $\mu$m) spectra taken with the Gemini Planet Imager as well as an updated $L_P$ (3.76 $\mu$m) and new $M_S$ (4.67 $\mu$m) photometry from the NIRC2 Narrow camera. The new data were combined with $J$ (1.13-1.35 $\mu$m) and $H$ (1.50-1.80 $\mu$m) spectra from the discovery epoch with the goal of better characterizing the planet properties. 51 Eri b photometry is redder than field brown dwarfs as well as known young T-dwarfs with similar spectral type (between T4-T8) and we propose that 51 Eri b might be in the process of undergoing the transition from L-type to T-type. We used two complementary atmosphere model grids including either deep iron/silicate clouds or sulfide/salt clouds in the photosphere, spanning a range of cloud properties, including fully cloudy, cloud free and patchy/intermediate opacity clouds. Model fits suggest that 51 Eri b has an effective temperature ranging between 605-737 K, a solar metallicity, a surface gravity of $\log$(g) = 3.5-4.0 dex, and the atmosphere requires a patchy cloud atmosphere to model the SED. From the model atmospheres, we infer a luminosity for the planet of -5.83 to -5.93 ($\log L/L_{\odot}$), leaving 51 Eri b in the unique position as being one of the only directly imaged planet consistent with having formed via cold-start scenario. Comparisons of the planet SED against warm-start models indicates that the planet luminosity is best reproduced by a planet formed via core accretion with a core mass between 15 and 127 M$_{\oplus}$.Comment: 27 pages, 19 figures, Accepted for publication in The Astronomical Journa
