GAAR: Gross Anatomy using Augmented Reality Mobile Application

Covid-19 pandemic has forced the teaching and learning activity into real time and real-world education meetings. The traditional physical and face-to-face meetings are avoided in accordance to reducing the close physical contacts among individuals. Thus, a new paradigm shift towards teaching and learning needs to be highly enforced. Teaching and learning on medical field especially require for real world anatomy against human or living things body. In response to providing the facility for medical teachers and learners, Gross Anatomy Augmented Reality (GAAR) is introduced. GAAR is an android mobile Augmented Reality (AR) learning tool to assist the educators and learners in internalizing 3D human anatomy with more fun and interactivity. The AR methodology is implied to attract the personal impacts and feelings towards operating of close to ‘real’ organ during anatomy practices. Traditional learning methods are changed with AR technology through small digital device. This application may be able to show the students the actual form of human gross anatomy and assist the teachers or educators’ in explaining the sciences behind human body in more interactive and interesting. Furthermore, this application uses a 3-dimensional object, video and interactive info so that students are interested in using this application. The AR for education and learning is vital in bridging the digital divide among all generations through the conversion of static pictures into real-like 3D animation. The implementation results show that, through the real visualization, small to adult learners can imitate the real truth on human organ and how this can motivate them to take care of their bodies that would lead to a healthier living styles as well as easy memorizing of the subject contents.

Michael Nyman: Composer in Progress; Michael Nyman: In Concert (review)

Michael Nyman: Composer in Progress; Michael Nyman: In Concert. DVD. Written and directed by Silvia Beck. [Germany]: Arthaus Musik, 2010. 101 526. $39.99. In 1993, Michael Nyman was blindsided by the overwhelming success of his film score for Jane Campion's The Piano. In crafting the voice for Holly Hunter's mute character, Ada, Nyman believed he was writing for a film with the reach of his collaborations with Peter Greenaway-art house fare little seen by mainstream audiences. However, The Piano exploded into the cultural consciousness, and Nyman's score, drenched with Scottish melodies subjected to his trademark style of motoric repetition and layering, went on to sell over three million copies. Nyman became an overnight success twenty years in the making. Even with the name recognition that came from The Piano, Nyman did not receive the imprimatur of the British musical establishment until sixteen years later when he was invited to perform at the 2009 BBC Proms in Royal Albert Hall. Silvia Beck's portrait of Nyman, fittingly called Composer in Progress, takes these two moments when Nyman bathed in the popular limelight as touchstones from which to explore the composer's diverse interests and activities. With seemingly full access both to Nyman and his core musicians, Beck has created a frustratingly fascinating film that provides tantalizing glimpses of the composer, but not a full portrait. Instead of a straight-forward chronological approach, Beck has opted to engage Nyman episodically. Where many filmmakers would seek entry into a composer's aesthetic by beginning at the beginning with childhood and music studies, Beck opens with influences on Nyman's music by focusing on his 1977 In Re Don Giovanni, a work that recontextualizes and rearticulates the first 16 bars of Leporello's catalogue aria through the lens of Jerry Lee Lewis-style rock. She then jumps to Nyman's film scores, particularly Peter Greenaway's The Draughtsman's Contract (which relies heavily on Purcell's music), Jane Campion's The Piano, and Volker Schlondorff's The Ogre, before digging into the makeup of The Michael Nyman Band and its performance at the BBC Proms. Interspersed among her three foci of recontextualization of older music, film music, and popular-music influenced performative style, Beck has peppered choice anecdotes to demonstrate Nyman's work outside of composition. We meet Steve Reich and hear how the famed minimalist convinced Nyman to return to composing after twelve years of music criticism, a time that resulted in the seminal book Experimental Music: Cage and Beyond. We observe Nyman taking photographs and video with small digital devices in Mexico City leading up to footage of his film Witness I. And we see him helping prepare and then perform at a festival of his music in Groningen in the Netherlands. However, throughout these episodes though we seek a common thread to help us categorize the thrust, impact, and import of Nyman's music, we never find it. That perspective, that thread, could have been delivered through interviews with his most important collaborators, particularly in film, but Beck only interviewed Volker Schlondorff, who in his two minutes on camera clearly articulates the subtexts Nyman's music brings to film and provides the most penetrating glimpse into Nyman's significance of the whole documentary. …

Fabrication of miniaturized Si-based electrocatalytic membranes

The increasing interest for lightweight and portable electronic systems, cellphones and small digital devices is driving technological research towards integrated regenerating power sources with small dimensions and great autonomy. Conventional batteries are already unable to deliver power in ever smaller volumes while maintaining the requirements of long duration and light weight. A possible solution to overcome these limits is the use of miniaturized fuel cells. The fuel cell offers a greater gravimetric energy density compared to conventional batteries. The micromachining technology of silicon is an important tool to reduce the fuel cell structure to micron sizes. The use of silicon also gives the opportunity to integrate the power source and the electronic circuits controlling the fuel cell on the same structure. This article reports preliminary results concerning the micromachining process for fabricating a silicon-based electrocatalytic membrane for miniaturized Si-based proton-exchange membrane (PEM) fuel cells.

Fabrication of miniaturised Si-based electrocatalytic membranes

The increasing interest for light and movable electronic systems, cell phones and small digital devices, drives the technological research toward integrated regenerating power sources with small dimensions and great autonomy. Conventional batteries are already unable to deliver power in more and more shrunk volumes maintaining the requirements of long duration and light weight. A possible solution to overcome these limits is the use of miniaturised fuel cell. The fuel cell offers a greater gravimetric energy density compared to conventional batteries. The micromachining technology of silicon is an important tool to reduce the fuel cell structure to micrometer sizes. The use of silicon also gives the opportunity to integrate the power source and the electronic circuits controlling the fuel cell on the same structure.

Surveillance of Water Pollution in a Tidal River by a State Estimator with Switching Structure

An estimator is presented for the surveillance of the organic pollution load in a tidal river when measurements are available only from sensors at larger distances. Due to the daily variation of the shape and range of the tide instationary flow conditions prevail and the estimator design is based on a dynamic hydromechanic river model which is kept simple enough to be processed on small digital devices in the field. From investigations of the structural properties of an Extended Kalman Filter applied to the problem a time constant estimator was developed. This estimator has a switching structure to cope with the inversion of flow direction by means of the interchange of input and output variables. Simulation results show that this estimator is capable to yield sufficiently reliable estimates under the instationary conditions in a tidal river

Precise Solutions of Linear Simultaneous Equations Using a Low Cost Analog

The device described in this paper reflects a general philosophy for the fuller utilization of analog computing devices which has been promoted at Watertown Arsenal Laboratory. When solutions of analog computers are used as tools in conjunction with techniques readily handled by standard desk calculators rather than as direct solutions, any desired accuracy of the final solution can be usually obtained. The emphasis is placed upon obtaining the equivalent of a large scale digital device by combining solutions from analog computers with techniques readily handled by very small digital devices.
