Intel iAPX 432: VLSI building blocks for a fault-tolerant computer
Authors: Dave Johnson, Dave Budde, Dave Carson, Craig Peterson
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

Early in 1983 two new VLSI components were added to the iAPX 432 family of components. The 43204 Bus Interface Unit (BIU) and the 43205 Memory Control Unit (MCU) extend the logical flexibility and robustness of the 432 processors into the physical implementation of 432 systems. The BIU and MCU provide a range of fault-tolerant system options. The components provide comprehensive detection facilities for processor operations as well as for the operation of buses and memories. Recovery is possible from permanent as well as transient errors. Detection and recovery are done totally in the VLSI components; there is no need for additional TTL logic or diagnostic software. This range of fault-tolerant capabilities is achieved by replication of VLSI components. VLSI replication provides software transparent migration over the full range of fault-tolerant options without any penalties for unused fault-tolerant facilities in low-end systems.

Authors: Yunxiang Gao, Chuangbai Xiao, Chaoqin Gao, Huiguang Chen
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

In order to meet the rapidly growing and changing needs of mobile instant messaging (IM), this paper provides a new service model and implementation mechanism based on Jabber and hierarchical thinking. The communication protocol of our system provides an open, expandable, real-time communication technology that can be used to build a wide range of XML applications. We use Linux C++, MySQL, and protocol conversion technology to develop the services of server and use J2ME technology to develop mobile client software. The system uses the newest network technology to supply WAP access and provide Web services. It is demonstrated by experiment that the system based on the hierarchical model can build stable and efficient mobile IM service that covers multimedia content sharing and corresponds with external services conveniently. It processes a message at an average of 4 milliseconds and the error rate is one ten thousandth.
Adaptive Resource Allocation in Multiuser OFDM System Based on Genetic Algorithm
Authors: Bo Liu, Mingyan Jiang, Dongfeng Yuan
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

Multiuser orthogonal frequency division multiplexing (MU-OFDM) is a promising technique for achieving high downlink capacities in future cellular and wireless local area network systems. The capacity of MU-OFDM can be maximized as long as subchannels and power are allocated adaptively, a new method based on genetic algorithm (GA) is proposed for adaptive power allocation in MU-OFDM system. Some proportional fairness constraints are also added to assure that each user can achieve a required data rate. Each subchannel to the user with the best channel-to-noise ratio has been assigned and an optimal power allocation algorithm based on GA has been proposed. The results demonstrate that the new method we proposed is optimal and efficient to resource allocation.
Learning to generalize for complex selection tasks
Authors: Alan Ritter, Sumit Basu
Venue: Proceedings of the 13th international conference on Intelligent user interfaces (2009)

Selection tasks are common in modern computer interfaces: we are often required to select a set of files, emails, data entries, and the like. File and data browsers have sorting and block selection facilities to make these tasks easier, but for complex selections there is little to aid the user without writing complex search queries. We propose an interactive machine learning solution to this problem called "smart selection," in which the user selects and deselects items as inputs to a selection classifier which attempts at each step to correctly generalize to the user's target state. Furthermore, we take advantage of our data on how users perform selection tasks over many sessions, and use it to train a label regressor that models their generalization behavior: we call this process learning to generalize. We then combine the user's explicit labels as well the label regressor outputs in the selection classifier to predict the user's desired selections. We show that the selection classifier alone takes dramatically fewer mouse clicks than the standard file browser, and when used in conjunction with the label regressor, the predictions of the classifier are significantly more accurate with respect to the target selection state.
Consistency between Task Models and Use Cases
Authors: Daniel Sinnig, Patrice Chalin, Ferhat Khendek
Venue: Engineering Interactive Systems: EIS 2007 Joint Working Conferences, EHCI 2007, DSV-IS 2007, HCSE 2007, Salamanca, Spain, March 22-24, 2007. Selected Papers (2008)

Use cases are the notation of choice for functional requirements documentation, whereas task models are used as a starting point for user interface design. In this paper, we motivate the need for an integrated development methodology in order to narrow the conceptual gap between software engineering and user interface design. This methodology rests upon a common semantic framework for developing and handling use cases and task models. Based on the intrinsic characteristic of both models we define a common formal semantics and provide a formal definition of consistency between task models and use cases. The semantic mapping and the application of the proposed consistency definition are supported by an illustrative example.

Walking Modeling Based on Motion Functions
Authors: Hao Zhang, Zhijing Liu
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

A modeling method of motion-function is presented to represent the motion in detection of video images within the physical and motional characters of body. It concentrates on the characters of video surveillance, with the examples of walking videos, and results in walking functions by extracting and dealing with the data from the experiments. On this basis, more experiments are required to validate all coefficients in functions, and induce final expressions of gait function and modeling.
Integrating a shrimp-growth function, farming skills information, and a supply allocation algorithm to manage the shrimp supply chain
Authors: Supachai Pathumnakul, Kullapapruk Piewthongngam, Sakda Khamjan
Venue: Computers and Electronics in Agriculture (2009)

This study examines the coordination problem in the Thai shrimp supply chain. Farming skills and demand seasonality play a crucial role in the chain inventory problem. The proposed purchasing allocation framework consists of a shrimp-growth model, database management and a supply allocation algorithm. The objective of the framework is to minimize overall inventory costs of the chain. Scenario analysis is used to demonstrate the application of the framework. The results show that different efficient plans are appropriate for different scenarios. Hence, establishing a precise plan will potentially reduce inventory cost. The supply allocation decision without a systematic plan would raise inventory cost and would lead to the production of excess shrimp of undesirable sizes. A strong coordination among all members in the chain will benefit all parties and better serve the customers.
Graspables: grasp-recognition as a user interface
Authors: Brandon T. Taylor, V. Michael Bove,  Jr.
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

The Graspables project is an exploration of how measuring the way people hold and manipulate objects can be used as a user interface. As computational ability continues to be implemented in more and more objects and devices, new interaction methods need to be developed. The Graspables System is embodied by a physical set of sensors combined with pattern recognition software that can determine how users hold a device. The Graspables System has been implemented in two prototypes, the Bar of Soap and the Ball of Soap. Applications developed for these prototypes demonstrate the effectiveness of grasp-recognition as an interface in multiple scenarios.
Stealthy video capturer: a new video-based spyware in 3G smartphones
Authors: Nan Xu, Fan Zhang, Yisha Luo, Weijia Jia, Dong Xuan, Jin Teng
Venue: Proceedings of the second ACM conference on Wireless network security (2009)

In this paper, we investigate video-based vulnerabilities in 3G Smartphones. Particularly, we design a new video-based spyware, called Stealthy Video Capturer (SVC). SVC can secretly record video information for the third party, greatly compromising Smartphone users' privacy. We implement the spyware and conduct extensive experiments on real world 3G Smartphones. Our experimental results show that the spyware can capture private video information with unremarkable power consumption, CPU and memory occupancy, hence being stealthy to Smartphone users. Moreover, SVC can naturally be resistant to almost all commercial anti-virus tools, like McAfee, Kaspersky and F-Secure mobile version. To the best of our knowledge, our work is the first one to address video-based vulnerabilities in 3G Smartphones. We expect our work will prompt serious attentions on this issue.
Infrastructure-based route optimization for NEMO based on combined local and global mobility
Authors: Christian Bauer, Serkan Ayaz, Max Ehammer, Thomas Gräupl, Fabrice Arnal
Venue: Proceedings of the International Conference on Mobile Technology, Applications, and Systems (2008)

Global mobility management protocols have been standardized and are gaining more and more momentum for deployment. At the same time network-based local mobility management has been identified as an important cornerstone for an overall mobility management framework and is currently covered by PMIPv6. However, local and global mobility management are separated and serve different purposes with little interaction. In the light of the work on NEMO route optimization we propose to combine both approaches more tightly, reusing existing functionality. We show how PMIPv6 can be used to build a network-based route optimization procedure for NEMO/MIPv6 based on globally distributed Home Agents. We also show that this approach can directly benefit from future evolvements of the PMIPv6 protocol.
Parallel H.264 Decoding on an Embedded Multicore Processor
Authors: Arnaldo Azevedo, Cor Meenderinck, Ben Juurlink, Andrei Terechko, Jan Hoogerbrugge, Mauricio Alvarez, Alex Ramirez
Venue: Proceedings of the 4th International Conference on High Performance Embedded Architectures and Compilers (2008)

In previous work the 3D-Wave parallelization strategy was proposed to increase the parallel scalability of H.264 video decoding. This strategy is based on the observation that inter-frame dependencies have a limited spatial range. The previous results, however, investigate application scalability on an idealized multiprocessor. This work presents an implementation of the 3D-Wave strategy on a multicore architecture composed of NXP TriMedia TM3270 embedded processors. The results show that the parallel H.264 implementation scales very well, achieving a speedup of more than 54 on a 64-core processor. Potential drawbacks of the 3D-Wave strategy are that the memory requirements increase since there can be many frames in flight, and that the latencies of some frames might increase. To address these drawbacks, policies to reduce the number of frames in flight and the frame latency are also presented. The results show that our policies combat memory and latency issues with a negligible effect on the performance scalability.
Computational Prediction of Abiotic Stress Responsible MicroRNAs in Vitis vinifera Genome
Authors: Zhenlin Wei
Venue: Proceedings of the 2009 International Conference on Electronic Computer Technology (2009)

In this paper, we predicted abiotic stress responsive microRNAs in wine grape genome by homolog search based on computational approach. We successfully predicted 18 grape microRMAs from total 12 query–microRNAs families which chosed from Arabidopsis,Oryza and Populus plants. The MiPred software prediction results, the stem-loop structure feature analysis and pol II promoter prediction results showed that these 18 putative microRNAs are real plant microRNAs. Several known cold, drought stress responding transcript factor binding motifs were identified in these 18 promoter regions. Word spyanalysis displayed 2 remarkable consensus motifs in these promoters with Arabidopsis microRNAs. Four groups of targets were predicted in this work, including CCAAT-binding transcription factor, ring finger transcription factor, sugar metabolism and transport proteins, methyl-transferase and some unknown grape proteins. 3 putative targets of vv-mirRNA169j, 477a and vv-miR393a have reverse transcriptase and leucine-rich repeats (LRRs)ribonuclease inhibitor activity.

Effect of low-frequency power on etching of SiCOH low-k films in CHF3 13.56MHz/2MHz dual-frequency capacitively coupled plasma
Authors: Chao Ye, Yijun Xu, Xiaojiang Huang, Zhenyu Xing, Jing Yuan, Zhaoyuan Ning
Venue: Microelectronic Engineering (2009)

This work investigates the etching characteristics of SiCOH low dielectric constant (low-k) films in the CHF"3 13.56MHz/2MHz dual-frequency capacitively couple plasma (CCP). The effect of low-frequency (LF) power on etching behavior is analyzed. The results show that the increase of LF power can leads to a transition of etching behavior from films deposition to etching. By Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) analysis on the etched SiCOH films and optical emission spectroscopy (OES) analysis on the plasma radicals, the transition behavior is found to relate to the suppression of C:F deposition due to the energetic ions sputtering and the increase of F concentration at higher LF power.
Decentralised decision making in heterogeneous teams using anonymous optimisation
Authors: George M. Mathews, Hugh Durrant-Whyte, Mikhail Prokopenko
Venue: Robotics and Autonomous Systems (2009)

This paper considers the scenario where multiple autonomous agents must cooperate in making decisions to minimise a continuous and differentiable team cost function. A distributed and asynchronous optimisation algorithm is presented which allows each agent to incrementally refine their decisions while intermittently communicating with the rest of the team. A convergence analysis provides quantitative requirements on the frequency agents must communicate that is prescribed by the structure of the decision problem. In general the solution method will require every agent to communicate to and have a model of every other agent in the team. To overcome this, a specific subset of systems, called Partially Separable, is defined. These systems only require each agent to have a combined summary of the rest of the team and allows each agent to communicate locally over an acyclic communication network, greatly increasing the scalability of the system.
Electronic portfolios: Perspectives of students, teachers and parents
Authors: Julie K. Mcleod, Sheri Vasinda
Venue: Education and Information Technologies (2009)

This study explores the perspectives of students, teachers and parents to evaluate the use of digital portfolios as an additional way to capture and enhance the learning of elementary students in a public school setting and as an opportunity to communicate this learning to parents. The research questions address four problems: complex assessment of learning, parental participation, and student and teacher satisfaction and the impact of the portfolio on teaching methods. Particularly, we are interested in the subjective satisfaction of students, teachers and parents in the portfolio development process. We are also interested in whether students learn to reflect constructively on their work, whether teachers have changed their teaching methods and whether parents believe the portfolio was used or could be used for enhanced communications.

Authors: D. A. May-Arrioja, N. Bickel, A. Alejo-Molina, M. Torres-Cisneros, J. J. Sanchez-Mondragon, P. LiKamWa
Venue: Microelectronics Journal (2009)

The intermixing characteristics of three widely used combinations of InP-based quantum wells (QW) are investigated using the impurity-free vacancy disordering (IFVD) technique. We demonstrate that the bandgap energy shift is highly dependent on the concentration gradient of the as-grown wells and barriers, as well as the thickness of the well, with thinner wells more susceptible to interdiffusion at the interface between the barrier and well. According to our results, the InGaAsP/InGaAsP and InGaAs/InP are well suited for applications requiring a wide range of bandgap values within the same wafer. In the case of the InGaAs/InGaAsP system, its use is limited due to the significant broadening of the photoluminescence spectrum that was observed. The effect of the top InGaAs layer over the InP cladding is also investigated, which leads to a simple way to obtain three different bandgaps in a single intermixing step.
MAPS: multi-algorithm parallel circuit simulation
Authors: Xiaoji Ye, Wei Dong, Peng Li, Sani Nassif
Venue: Proceedings of the 2008 IEEE/ACM International Conference on Computer-Aided Design (2008)

The emergence of multi-core and many-core processors has introduced new opportunities and challenges to EDA research and development. While the availability of increasing parallel computing power holds new promise to address many computing challenges in CAD, the leverage of hardware parallelism can only be possible with a new generation of parallel CAD applications. In this paper, we propose a novel Multi-Algorithm Parallel circuit Simulation approach (MAPS) and its multi-core implementation to expedite one of the most fundamental CAD applications: transistor-level transient circuit simulation. MAPS starts multiple simulation algorithms in parallel for a given simulation task. By properly synchronizing these algorithms on-the-fly, we exploit the diversity in simulation algorithms to achieve possibly superlinear overall speedup in transient simulation. In addition, our unique multi-algorithm framework allows unique safe exploration of simulation methods that are conventionally discarded due to convergence concerns. As a coarse grained parallel simulation approach, the implementation of MAPS demands a minimum of parallel programming effort and allows for reuse of existing serial simulation codes.

Authors: Mooseop Kim, Jaecheol Ryou, Sungik Jun
Venue: Information Security Applications: 9th International Workshop, WISA 2008, Jeju Island, Korea, September 23-25, 2008, Revised Selected Papers (2009)

We present a compact SHA-1 hardware architecture suitable for the Mobile Trusted Module (MTM) that requires low-area and low-power characteristics. The built-in SHA-1 engine in MTM is one of the most important circuit blocks and contributes the performance of the whole platform because it is used as key primitives supporting platform integrity and command authentication. Unlike personal computers, mobile platform have very stringent limitations with respect to available power, physical circuit area, and cost. Therefore special architecture and design methods for a compact SHA-1 hardware module are required. Our SHA-1 hardware can compute 512-bit data block using 6,812 gates on a 0.25μm CMOS process. The highest operation frequency and throughput of the proposed architecture are 114MHz and 164Mbps, which satisfies processing requirement for the mobile application.

Authors: Nadezhda Govedarova, Stanimir Stoyanov, Ivan Popchev
Venue: Proceedings of the 9th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing (2008)

In this paper we present otology-based architecture for knowledge management in BULCHINO web-based catalogue for Bulgarian cultural heritage. Our approach for realizing content-based search and retrieval in the catalogue implies the application of the CBR technology for the representation of metadata characterizations of the cultural objects and the integration of ontology for semantic formalization of these characterizations. We provide an insight of the technical aspects of the architecture by enumerating the technological requirements, where we pay specific attention to the CBR framework jCOLIBRI and its features for implementing concept-based similarity assessment.
Silhouette quality quantification for gait sequence analysis and recognition
Authors: Jianyi Liu, Nanning Zheng, Lei Xiong
Venue: Signal Processing (2009)

Most gait analysis and recognition algorithms are designed based on silhouette data. Their recognition performances may therefore be impaired by the poor quality silhouettes extracted from outdoor environments. In this paper, a silhouette quality quantification (SQQ) method is proposed to assess the quality of silhouette sequence. SQQ analyzes the sequence quality based on 1D foreground-sum signal modeling and signal processing technique. As an immediate application of SQQ, a general enhancement framework namely silhouette quality weighting (SQW) is designed toward improving most of the current gait recognition algorithms by taking into consideration sequence quality. The experiments are performed on the USF HumanID gait dataset v1.7 (with 71 subjects). Investigation using the SQQ criterion has revealed the baseline algorithm's mechanism of silhouette quality consideration. Two instantiations of the SQW algorithm based on gait energy image (GEI) are implemented. Improved recognition performances compared to the original GEI and baseline methods are obtained, which verifies the effectiveness of the proposed SQQ, SQW methods.
