Book review "Moving Innovation: A History of Computer Animation by Tom Sito , The MIT Press: Cambridge, MA, 2013"

As a Lecturer of Animation History and 3D Computer Animator, I received a copy of Moving Innovation: A History of Computer Animation by Tom Sito with an element of anticipation in the hope that this text would clarify the complex evolution of Computer Graphics (CG). Tom Sito did not disappoint, as this text weaves together the multiple development streams and convergent technologies and techniques throughout history that would ultimately result in modern CG. Universities now have students who have never known a world without computer animation and many students are younger than the first 3D CG animated feature film, Toy Story (1996); this text is ideal for teaching computer animation history and, as I would argue, it also provides a model for engaging young students in the study of animation history in general. This is because Sito places the development of computer animation within the context of its pre-digital ancestry and throughout the text he continues to link the discussion to the broader history of animation, its pioneers, technologies and techniques...

Gde moi kryl'ja? Analiz fil'ma Alekseja Balabanova »Brat»

Tutkielma on analyysi Aleksej Balabanovin ohjaamasta elokuvasta Brat (1997). Ensimmäisessä osassa tarkastellaan Brat-elokuvaa satuna jäsentämällä sen henkilöhahmoja ja rakennetta Vladimir Proppin satujen morfologisen analyysin pohjalta. Tärkeimmille henkilöhahmoille on mahdollista löytää vastineet satujen perushahmoista, mutta elokuvasta löytyy näille hahmoille myös erityisiä valheellisia variantteja, selkeimpänä esimerkkinä veljespari Danila – sankari ja Vitja – valheellinen sankari. Myös juonenkulusta on jäsennettävissä sekä varsinainen, että valheellinen juonenkulku: varsinainen juonenkulku käsittelee päähenkilön suhdetta veljeensä, sekä heidän yhteiseen viholliseensa, valheellinen juonenkulku puolestaan päähenkilön suhdetta tarinan potentiaaliseen sankarittareen. Lisäksi elokuvasta löytyy myös kolmas, vaihtoehtoinen juonenkulku, joka liittyy musiikin funktioon elokuvassa. Toisessa osassa analysoidaan päähenkilön suhdetta muihin henkilöhahmoihin sekä ympäröivään yhteiskuntaan käsitteiden horisontaali ja vertikaali avulla. Nämä käsitteet osittain limittyvät Vladimir Papernyin teoriaan Kul’tura 2. Analyysin lähtökohtana on, että elokuvan toiminta käynnistyy sankarin pyrkimyksestä löytää oma viiteryhmänsä ja sitä kautta identiteettinsä. Isän menetyksestä, niin konkreettisesti perheen kuin symbolisesti yhteiskunnan tasolla, seuraa horisontaalin ja vertikaalin oppositio; perheyhteisön ja yhteiskunnan hajoaminen. Päähenkilön kohtaamat henkilöhahmot voidaan jakaa vertikaali- ja horisontaalivariantteihin sen mukaan, mitä arvoja nämä edustavat. Tässä yhteydessä käsitellään myös sitä, miten veljeyteen ja kansallisuuten pohjautuvat identiteetinmuodostamiskeinot epäonnistuvat, sekä miten horisontaalius ja vertikaalius, auktoriteetin ja veljeyden teemat, toteutuvat elokuvan kuvakompositioissa. Kolmannessa osassa tarkastellaan elokuvan tapahtumapaikkoja ja minkälaisia oppositioita ne muodostavat. Konkreettisesti edustettujen oppositioiden maaseutu – kaupunki, sekä Pietari – Moskova lisäksi asettuvat vastakkain myös rikollisten ja tavallisten ihmisten Pietari, ulko- ja sisätilat, sekä yleinen ja yksityinen tila. Pietarin kuvaamiseen käytetyillä oppositioilla on selviä yhtymäkohtia Vladimir Toporovin esittämään pietarilaistekstien traditioon. Viimeisessä osassa käsitellään musiikin diegeettistä funktiota Bratissa. Se toimii elokuvassa vaihtoehtoisena juonenkulkuna, konkreettisena viiteryhmän etsimisen ja identiteetin muodostamisen keinona, sekä omana, erillisenä ’fantastisena’ tilanaan. Toiminta-/rikoselokuva oli vielä 1990-luvulla suhteellisen vieras genre venäläisessä elokuvassa. Tämä analyysi osoittaa, miten tiiviisti Brat kuitenkin asettuu venäläisen kulttuurin kontekstiin. Se käy dialogia niin venäläisen kansansatuperinteen, kuin 1800-luvun pietarilaistekstien kanssa, ja soveltuu tarkasteltavaksi myös kahden venäläisen kulttuurin vaihtelun teoriaa vasten. Vaikka Bratilla ei suoria elokuvallisia edeltäjiä Venäjällä olekaan, sen teemat ovat perivenäläisiä.

Beth Israel Hospital (Boston, MA) Records, undated, 1923, 1930-1964, 1988, 1991-1992

In 1916, the Jewish community of Boston established Beth Israel Hospital on Townsend Street in Roxbury to provide health care to immigrants in the area. Although accessible to everyone, the hospital provided Yiddish-speaking services for Eastern European Jewish immigrants and served kosher food, as well as conducted Jewish religious services. In 1928 the hospital entered into a teaching agreement with Harvard Medical School, Tufts University, and Simmons College. Shortly thereafter, the hospital moved to its current location in the Longwood area of Boston and expanded to a 220-bed operation. During 1935-1936, at the height of the Depression, Beth Israel spent 1.5 million dollars in free patient care and was only one of two local hospitals to offer health care to people on welfare. In 1996, Beth Israel Hospital merged with Deaconess Medical Center and became Beth Israel Deaconess Medical Center. This collection contains reports, pamphlets and hospital publications.

Ma Ma Ma Mad

Ma Ma Ma Mad is an autobiographical work, written and performed by Singaporean-Australian theatre maker Merlynn Tong. This production, presented at the Brisbane Powerhouse in December 2015, was a multi-genre work incorporating aspects of Butoh, physical theatre, cabaret and contemporary monologue. More than an experiment in mixed performative forms, however, this particular production was also an exercise in inter-cultural collaboration as well as gender in (and of) performance. Heavily influenced by the creator's experiences growing up in urban Southeast Asia, the director's specialisation in contemporary Australian theatre and experience telling uniquely Australian stories worked to manipulate the form in an endeavour to succinctly speak to local audiences, without pandering to entrenched stereotypes or diluting the underlying Chinese-Singaporean themes. The success of this production was also somewhat of a personal challenge for the creatives, after being told by some of Brisbane's most influential theatre venues and festivals that they would rather not support the work because a) it was a one woman show, and b) it was a one woman show about an Asian woman; and therefore would not sell well. One very influential local producer even said that he already had a one-woman show about an Asian person programmed, so he couldn't possibly program another. Operating in such a biased and out-of-touch artistic environment was seen as an easy challenge for the artists involved, which resulted in a highly successful and critically acclaimed sell-out run of Ma Ma Ma Mad, followed by offers to tour the work nationally and internationally. As such, this production also stands as a practical example of the ingrained and patriarchal structures of the Australian arts scene, and how art can work to break down the very barriers that it has helped to construct through a lack of vision and diversity amongst its leaders.

Hot deformation characteristics of INCONEL alloy MA 754 and development of a processing map

The characteristics of hot deformation of INCONEL alloy MA 754 have been studied processing maps obtained on the basis of flow stress data generated in compression in the temperature range 700-degrees-C to 1150-degrees-C and strain rate range 0.001 to 100 s-1. The map exhibited three domains. (1) A domain of dynamic recovery occurs in the temperature range 800-degrees-C to 1075-degrees-C and strain rate range 0.02 to 2 s-1, with a peak efficiency of 18 pct occurring at 950-degrees-C and 0.1 s-1. Transmission electron microscope (TEM) micrographs revealed stable subgrain structure in this domain with the subgrain size increasing exponentially with an increase in temperature. (2) A domain exhibiting grain boundary cracking occurs at temperatures lower than 800-degrees-C and strain rates lower than 0.01 s-1. (3) A domain exhibiting intense grain boundary cavitation occurs at temperatures higher than 1075-degrees-C. The material did not exhibit a dynamic recrystallization (DRX) domain, unlike other superalloys. At strain rates higher than about 1 s-1, the material exhibits flow instabilities manifesting as kinking of the elongated grains and adiabatic shear bands. The material may be safely worked in the domain of dynamic recovery but can only be statically recrystallized.

Direct Numerical Simulation of a Spatially Evolving Supersonic Turbulent Boundary Layer at Ma=6

Direct numerical simulation is carried out for a spatially evolving supersonic turbulent boundary layer at free-stream Mach number 6. To overcome numerical instability, the seventh-order WENO scheme is used for the convection terms of Navier-Stokes equations, and fine mesh is adopted to minimize numerical dissipation. Compressibilty effects on the near-wall turbulent kinetic energy budget are studied. The cross-stream extended self-similarity and scaling exponents including the near-wall region are studied. In high Mach number flows, the coherence vortex structures are arranged to be smoother and streamwised, and the hair-pin vortices are less likely to occur.

Coherent Structures in Transition of a Flat-Plate Boundary Layer at Ma=0.7

Direct numerical simulation (DNS) of a spatially evolving flat-plate boundary layer transition process at free stream Mach number 0.7 is performed. Tollmien-Schlichting (T-S) waves are added on the inlet boundary as the disturbances before transition. Typical coherent structures in the transition process are investigated based on the second invariant of velocity gradient tensor. The instantaneous shear stress and the mean velocity profile in the transition region are studied. In our view, the fact that the peak value of shear stress in the stress concentration area increases and exceeds a threshold value during the later stage of the transition process plays an important role in the laminar breakdown process.

FTT-MA: A Flexible Time-Triggered Middleware Architecture for Time Sensitive, Resource-Aware AmI Systems

There is an increasing number of Ambient Intelligence (AmI) systems that are time-sensitive and resource-aware. From healthcare to building and even home/office automation, it is now common to find systems combining interactive and sensing multimedia traffic with relatively simple sensors and actuators (door locks, presence detectors, RFIDs, HVAC, information panels, etc.). Many of these are today known as Cyber-Physical Systems (CPS). Quite frequently, these systems must be capable of (1) prioritizing different traffic flows (process data, alarms, non-critical data, etc.), (2) synchronizing actions in several distributed devices and, to certain degree, (3) easing resource management (e.g., detecting faulty nodes, managing battery levels, handling overloads, etc.). This work presents FTT-MA, a high-level middleware architecture aimed at easing the design, deployment and operation of such AmI systems. FTT-MA ensures that both functional and non-functional aspects of the applications are met even during reconfiguration stages. The paper also proposes a methodology, together with a design tool, to create this kind of systems. Finally, a sample case study is presented that illustrates the use of the middleware and the methodology proposed in the paper.
