A model for adapting 3D graphics based on scalable coding, real-time simplification and remote rendering

Most current multiplayer 3D games can only be played on dedicated platforms, requiring specifically designed content and communication over a predefined network. To overcome these limitations, the OLGA (On-Line GAming) consortium has devised a framework to develop distributive, multiplayer 3D games. Scalability at the level of content, platforms and networks is exploited to achieve the best trade-offs between complexity and quality

Extending the Internet of Things to the future Internet through IPv6 Support

Emerging Internet of Things (IoT)/Machine-to-Machine (M2M) systems require a transparent access to information and services through a seamless integration into the Future Internet. This integration exploits infrastructure and services found on the Internet by the IoT. On the one hand, the so-called Web of Things aims for direct Web connectivity by pushing its technology down to devices and smart things. On the other hand, the current and Future Internet offer stable, scalable, extensive, and tested protocols for node and service discovery, mobility, security, and auto-configuration, which are also required for the IoT. In order to integrate the IoT into the Internet, this work adapts, extends, and bridges using IPv6 the existing IoT building blocks (such as solutions from IEEE 802.15.4, BT-LE, RFID) while maintaining backwards compatibility with legacy networked embedded systems from building and industrial automation. Specifically, this work presents an extended Internet stack with a set of adaptation layers from non-IP towards the IPv6-based network layer in order to enable homogeneous access for applications and services

Sensorineural hearing loss enhances auditory sensitivity and temporal integration for amplitude modulation.

Amplitude-modulation detection thresholds (AMDTs) were measured at 40 dB sensation level for listeners with mild-to-moderate sensorineural hearing loss (age: 50-64 yr) for a carrier frequency of 500 Hz and rates of 2 and 20 Hz. The number of modulation cycles, N, varied between two and nine. The data were compared with AMDTs measured for young and older normal-hearing listeners [Wallaert, Moore, and Lorenzi (2016). J. Acoust. Soc. Am. 139, 3088-3096]. As for normal-hearing listeners, AMDTs were lower for the 2-Hz than for the 20-Hz rate, and AMDTs decreased with increasing N. AMDTs were lower for hearing-impaired listeners than for normal-hearing listeners, and the effect of increasing N was greater for hearing-impaired listeners. A computational model based on the modulation-filterbank concept and a template-matching decision strategy was developed to account for the data. The psychophysical and simulation data suggest that the loss of amplitude compression in the impaired cochlea is mainly responsible for the enhanced sensitivity and temporal integration of temporal envelope cues found for hearing-impaired listeners. The data also suggest that, for AM detection, cochlear damage is associated with increased internal noise, but preserved short-term memory and decision mechanisms.N.W. was supported by a grant from Neurelec Oticon Medical.

Kajian Terjemahan Struktur dan Pola Pengembangan Tema pada Artikel Fleeing Terror, Finding Refuge ke dalam Bahasa Indonesia

This research is conducted by analyzing the thematic structure and progression of the the March 2015 National Geographic article Fleeing Terror, Finding Refuge and its March 2015 National Geographic Indonesia Indonesian translation Mencari Tempat Berlindung. This research aims to describe: (1) its thematic structure and progression, (2) the translation techniques employed and its effect on the translation’s thematic structure and progression, and (3) its effect on the translation quality. This study belongs to the qualitative research at the descriptive level, employs embedded case study approach, and focuses on the translation product. The data sources consist of the document in the form of the March 2015 National Geographic article Fleeing Terror, Finding Refuge and its March 2015 National Geographic Indonesia Indonesian translation Mencari Tempat Berlindung and informants selected based on some pre-determined criteria (criterion-based sampling) who will then be required to give their assessment regarding the translation quality. The data consist of the Themes of the National Geographic March 2015 article Fleeing Terror, Finding Refuge and its National Geographic Indonesia March 2015 Indonesian translation Mencari Tempat Berlindung collected through content analysis and the result of the informant’s translation quality assessment collected through questionnaire and focus group discussion. The data were analyzed according to the Miles et al. (2014) interactive model. The result shows that shifts in thematic structure and progression occur in the translation. It also shows that there are 12 translation techniques employed: established equivalent, transposition, amplification, borrowing, variation, modulation, reduction, linguistic amplification, particularization, generalization, linguistic compression, and adaptation. The majority of the data involves no shift and is accurate, acceptable, and has high readability. This study revealed that the translation employs more marked Topical Theme than the source text and the percentage of the translation’s Rheme-based progressions (the simple linear and split Rheme progression) is higher than the source text’s. The thematic structure shifts (mostly a shift from the unmarked to the marked Topical Theme (or vice-versa) or a change in the Topical Theme constituent) can be caused by the use of these six translation techniques: transposition, modulation, reduction, amplification, established equivalent, and particularization. Of these six, particularization does not cause any Thematic progression shift. These six techniques that can cause a shift in the Thematic structure can also decrease the translation’s quality. Keywords: Thematic structure, Thematic progression, translation techniques, translation quality assessmen

Multilayers Fast Mode Decision Algorithms for Scalable Video Coding

Abstract: Scalable video coding (SVC) is the extension of H.264/AVC standard. The features in SVC are also developed from the H.264/AVC standard, so that SVC has more features compared to H.264/AVC standard. This provides higher coding complexity in SVC encoder which causes higher encoding time for SVC. SVC is gaining great interest because of its ability and scalability to adapt in various network conditions. SVC allows partial transmission and decoding of a bitstream. This research deals with multilayers fast mode decision algorithm for decreasing encoding time or fastening the mode decision process of the SVC encoder. The proposed fast mode decision scheme has been implemented and is successfully decrease encoding time with negligible loss of quality and bitrate requirement. The simulation result shows the proposed fast mode decision algorithm provides time saving up to 45 % while maintaining video quality with negligible PSNR loss
