Invited Talk 3: Foundry Full-Scale Reliability Testing Capability Setup for Advanced Technology
Authors: Kary Chien
Venue: Proceedings of the 16th Asian Test Symposium (2007)

To facilitate the business fast-growing and meet reliability test requirements of advanced technology development and multiple types of products, it is necessary to establish a flexible, fast-responsible, and efficient full-scale reliability testing capability. The reliability testing capability should cover all segments including technology development and qualification, process monitor and reliability assessment of process issues. Innovative test structure like matrix gate oxide structure was designed to improve wafer level reliability (WLR) test efficiency and probe contact resistance (PCR) calibration tool was developed to enhance test accuracy. The side braze assembly (SBA) line was established and significantly reduced the sample preparation cycle time. Moreover, it provides the flexibility to support complicated ESD/ function & design verifications, and product reliability studies using our innovative high-pin-count package solutions. Anti-ESD solution kits were developed to prevent ESD damage during sample preparation & package reliability testing in advanced technology node. Advanced test during burn in (TDBI) system was established to extend the test capability from memory device to mix-signal device. In-house Chip probing (CP) system deepens our understanding on correlation among CP, final test (FT) and reliability performance. Build-in reliability diagnosis system (BIRDS) was formed to manage the reliability data and ensures data integrity. It also creates an opportunity for reliability data systematical statistic analysis.

An Improved Anisotropic Diffusion PDE for Noise Removal and Edge Preservation
Authors: Zhifeng Wang, Xiaomao Li, Yandong Tang
Venue: Proceedings of the Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing - Volume 01 (2007)

In this paper, an improved anisotropic nonlinear diffusion equation for image restoration is presented. As a corner in an image is rounded when using degenerated diffusion equation to smooth the image, it proposed to use both the gradient and the second order directional derivative in the direction orthogonal to the gradient to control the diffusion velocity. It can remove noise and perform stably. It can also enhance step-like edges and keep the locality of them. Compared with other method, it is capable of keeping stronger peaks and thin edges. Due to these characteristics, not only the processed noisy image look much more clear and smooth, but also the details are kept, resulting in the naturalness. The experiment results are very satisfactory.

Authors: Yantao Shen, Nandagopal S. Methil, Craig A. Pomeroy, Ning Xi, Ranjan Mukherjee, Danyu Zhu, Zhiwei Cen, James Yang, Matt W. Mutka, Carol A. Slomski, Keith N. Apelgren
Venue: International Journal of Robotics Research (2007)

We present our development of a supermedia interface for telediagnostics of breast pathology via the Internet. Supermedia is the incorporation of multiple media and data streams, such as audio, video, ultrasound images, and tactile and haptic sensor data for enhanced telepresence capabilities. Our supermedia interface comprises an anthropomorphic arm/hand equipped with haptic and tactile sensing, ultrasound imaging capabilities, a physician interface capable of rendering both haptic and tactile information, and two-way audio and video. The supermedia interface was tested via the Internet and enables telediagnostics. Preliminary experiments with silicone breast models have demonstrated the e fectiveness of the supermedia interface for telediagnostics. The interface is expected to enhance and improve the diagnostic performance of breast pathology as well as promote telediagnostics in remote areas and for patients with cultural barriers.
Word image based latent semantic indexing for conceptual querying in document image databases
Authors: Sameek Banerjee, Gaurav Harit, Santanu Chaudhury
Venue: Proceedings of the Ninth International Conference on Document Analysis and Recognition - Volume 02 (2007)

In this paper we present an application of latent semantic analysis (LSA) for indexing and retrieval of document images with text. The query is specified as a set of word images and the documents which best match with the query representation in the the latent semantic space are retrieved. We show through extensive experiments on a large database that use of LSA for document images provides improvements in retrieval precision as is the case with electronic text documents.

Pseudo primitive idempotents and almost 2-homogeneous bipartite distance-regular graphs
Authors: Michael S. Lang
Venue: European Journal of Combinatorics (2008)

Let @C denote a bipartite distance-regular graph with diameter D>=4, valency k>=3 and intersection numbers c"i, b"i(0@?i@?D). By a pseudo cosine sequence of @C we mean a sequence of scalars @s"0,...,@s"D such that @s"0=1 and c"i@s"i"-"1+b"i@s"i"+"1=k@s"1@s"i for 1@?i@?D-1. By an associated pseudo primitive idempotent we mean a nonzero scalar multiple of the matrix @?"i"="0^D@s"iA"i, where A"0,...,A"D are the distance matrices of @C. Our main result is the following: Let @s"0,...,@s"D denote a pseudo cosine sequence of @C with @s"1@?{-1,1} and let E denote an associated pseudo primitive idempotent. The following are equivalent: (i) the entrywise product of E with itself is a linear combination of the all-ones matrix and a pseudo primitive idempotent of @C; (ii) there exists a scalar @b such that @s"i"-"1-@b@s"i+@s"i"+"1=0 for 1@?i@?D-1. Moreover, @C has such a pseudo cosine sequence and pseudo primitive idempotent if and only if @C is almost 2-homogeneous with c"2>=2.
Tornado Codes for MAID Archival Storage
Authors: Matthew Woitaszek, Henry M. Tufo
Venue: Proceedings of the 24th IEEE Conference on Mass Storage Systems and Technologies (2007)

This paper examines the application of Tornado Codes, a class of low density parity check (LDPC) erasure codes, to archival storage systems based on massive arrays of idle disks (MAID). We present a logstructured extent-based archival file system based on Tornado Coded stripe storage. The file system is combined with a MAID simulator to emulate the behavior of a large-scale storage system with the goal of employing Tornado Codes to provide fault tolerance and performance in a power-constrained environment. The effect of power conservation constraints on system throughput is examined, and a policy of placing multiple data nodes on a single device is shown to increase read throughput at the cost of a measurable, but negligible, decrease in fault tolerance. Finally, a system prototype is implemented on a 100 TB Lustre storage cluster, providing GridFTP accessible storage with higher reliability and availability than the underlying storage architecture.

In this paper we present a method of robustly detect cir- cles in a line drawing image. The method is fast, robust and very reliable, and is capable of assessing the quality of its detection. It is based on Random Sample Consensus mini- mization, and uses techniques that are inspired from object tracking in image sequences.

Tuple routing strategies for distributed eddies
Authors: Feng Tian, David J. DeWitt
Venue: Proceedings of the 29th international conference on Very large data bases - Volume 29 (2003)

Many applications that consist of streams of data are inherently distributed. Since input stream rates and other system parameters such as the amount of available computing resources can fluctuate significantly, a stream query plan must be able to adapt to these changes. Routing tuples between operators of a distributed stream query plan is used in several data stream management systems as an adaptive query optimization technique. The routing policy used can have a significant impact on system performance. In this paper, we use a queuing network to model a distributed stream query plan and define performance metrics for response time and system throughput. We also propose and evaluate several practical routing policies for a distributed stream management system. The performance results of these policies are compared using a discrete event simulator. Finally, we study the impact of the routing policy on system throughput and resource allocation when computing resources can be shared between operators.
The affective dimension of pervasive themes in the information technology curriculum
Authors: Charles W. Reynolds, Bryan S. Goda
Venue: Proceedings of the 8th ACM SIGITE conference on Information technology education (2007)

The pervasive themes cited by the IT2005 Information Technology Model Curriculum are system integration, use of abstraction, user advocacy, information assurance, adaptability, professionalism and outstanding interpersonal skills. These are aspects of what we teach that pervade and tie together the IT discipline, aspects whose understanding identifies the IT professional. Pervasive themes can be characterized (Meyer,Land[14]) as transformative (change how students think), irreversible (once understood, are never forgotten), integrative (provide a framework for understanding previous concepts), boundin(serve as discipline boundaries in that understanding them identifies someone as a member of the discipline), troublesome (are difficult to teach and learn). This paper illustrates each of these characteristics using the IT pervasive themes and then proposes that an essential aspect of a pervasive theme is that it has an affective component. That is, in addition to cognitive elements (knowledge and intellectual skills), a pervasive theme includes educational objectives that treat values and attitudes. Just as cognitive objectives have a well-known hierarchy of cognitive difficulty, so also affective objectives have a (less well-known) hierarchy of increasing value commitment in which affective objectives can be placed and classified. This paper discusses the affective component in the IT2005 pervasive themes, how they are specified and classified, and how they are achieved using inculcation, role models, role playing, values clarification and analysis, and educational tasks that include natural affective consequences such as project development for real clients.
Fast Recovery from Hidden Node Collision for IEEE 802.15.4 LR-WPANs
Authors: Shengzhi Zhang, Sang-Jo Yoo
Venue: Proceedings of the 7th IEEE International Conference on Computer and Information Technology (2007)

RTS/CTS mechanism to avoid the hidden/exposed node problem, for the consideration of constructing the low energy consumption networks. However, based on the modified CSMA/CA algorithm in LR-WPANs, the hidden node collisions will repeat up to aMaxframeRetries (default value is 3) times until the collided packets are discarded with a high probability. Therefore, a fast recovery mechanism is proposed in this paper to achieve the fast self-healing with negligible control overheads when the networks suffer the hidden node collisions. When the coordinator recognizes the hidden node collision occurs, it will issue a group polling ACK (PACK) to indicate the priority of the collided packets retransmission. Simulation results demonstrate that the proposed PACK mechanism is able to improve the network throughput and avoid the continuous hidden node collisions efficiently. Keywords- LR-WPAN; Hidden node collision; ACK I.
The visual active memory perspective on integrated recognition systems
Authors: C. Bauckhage, S. Wachsmuth, M. Hanheide, S. Wrede, G. Sagerer, G. Heidemann, H. Ritter
Venue: Image and Vision Computing (2008)

Object recognition is the ability of a system to relate visual stimuli to its knowledge of the world. Although humans perform this task effortlessly and without thinking about it, a general algorithmic solution has not yet been found. Recently, a shift from devising isolated recognition techniques towards integrated systems could be observed [Y. Aloimonos, Active vision revisited, in: Y. Aloimonos (Ed.), Active Perception, Lawrence Efibaum, 1993, pp. 1-18; H. Christensen, Cognitive (vision) systems, ERCIM News (April, 2003). 17-18]. The visual active memory (VAM) perspective refines this system view towards an interactive computational framework for recognition systems in human everyday environments. VAM is in line with the recently emerged Cognitive Vision paradigm [H. Christensen, Cognitive (vision) systems, ERCIM News (April, 2003). 17-18] which is concerned with vision systems that evaluate, gather and integrate contextual knowledge for visual analysis. It consists of active processes that generate knowledge by means of a tight cooperation of perception, reasoning, learning and prior models. In addition, VAM emphasizes the dynamic representation of gathered knowledge. The memory is assumed to be structured in a hierarchy of successive memory systems that mediate the modularly defined processing components of the recognition system. Recognition and learning take place in the stress field of objects, actions, activities, scene context, and user interaction. In this paper, we exemplify the VAM perspective by means of existing demonstrator systems. Assuming three different perspectives (biological foundation, system engineering, and computer vision), we will show that the VAM concept is central to the cognitive capabilities of the system and that it leads to a more general object recognition framework.
Finding optimal hardware/software partitions
Authors: Zoltán Ádám Mann, András Orbán, Péter Arató
Venue: Formal Methods in System Design (2007)

Most previous approaches to hardware/software partitioning considered heuristic solutions. In contrast, this paper presents an exact algorithm for the problem based on branch-and-bound. Several techniques are investigated to speed up the algorithm, including bounds based on linear programming, a custom inference engine to make the most out of the inferred information, advanced necessary conditions for partial solutions, and different heuristics to obtain high-quality initial solutions. It is demonstrated with empirical measurements that the resulting algorithm can solve highly complex partitioning problems in reasonable time. Moreover, it is about ten times faster than a previous exact algorithm based on integer linear programming. The presented methods can also be useful in other related optimization problems.
Profiling online learners: insights gained from learning indicators, learner behaviors and learner perceptions
Authors: Des Casey, Janet Fraser, David Murphy
Venue: Proceedings of the sixth conference on IASTED International Conference Web-Based Education - Volume 2 (2007)

This study constructs a learner profile for online learners using the Walkabout Ubiquitous Learning Environment. The learner profile is constructed from data collected on learning indicators, learner behaviors and learner perceptions of the environment. The constructed profile indicates that learners are content to work independently, without any great need to interact with teaching staff or other students, perform as well as learners with access to lectures and tutorials, adopt a traditional study pattern even though they are using a flexible environment. They like the flexibility offered, but also look for some imposed time based structures as an aid to learning. This study also compares these findings to those of other researchers.

Genetic algorithms, selection schemes, and the varying effects of noise
Authors: Brad L. Miller, David E. Goldberg
Venue: Evolutionary Computation (1996)

This paper analyzes the effect of noise on different selection mechanisms for genetic algorithms (GAs). Models for several selection schemes are developed that successfully predict the convergence characteristics of GAs within noisy environments. The selection schemes modeled in this paper include proportionate selection, tournament selection, (μ, λ) selection, and linear ranking selection. An allele-wise model for convergence in the presence of noise is developed for the OneMax domain, and then extended to more complex domains where the building blocks are uniformly scaled. These models are shown to accurately predict the convergence rate of GAs for a wide range of noise levels.

A Framework to Enable Offshore Outsourcing
Authors: Andreas Braun
Venue: Proceedings of the International Conference on Global Software Engineering (2007)

Offshore outsourcing (offshoring) is increasingly important in IT projects. The anticipated gains are primarily cost savings and span to -- amongst others -- shorter time-to-market, address scarce qualified labor force, bypass local regulations, laws, and taxes, and work following the sun. However, many offshoring IT projects fail [3] and significantly miss their anticipated improvements mainly due to cost and quality issues.. We identified categories of projects that are likely to perform well in an offshoring scenario and some that won't. They are related to specific business processes, differences in language (client vs. offshore partners), and tacit knowledge. The paper at hand specifically regards the latter category of projects and suggests an offshoring framework to enable distributed, blended workforce in a real-world business context. The framework has been developed in large scale projects with IT service firms and consultancies and has been evaluated in a large distributed project [2] [6].
Continuous-index hidden Markov modelling of array CGH copy number data
Authors: Susann Stjernqvist, Tobias Rydén, Martin Sköld, Johan Staaf
Venue: Bioinformatics (2007)

Motivation: In recent years, a range of techniques for analysis and segmentation of array comparative genomic hybridization (aCGH) data have been proposed. For array designs in which clones are of unequal lengths, are unevenly spaced or overlap, the discrete-index view typically adopted by such methods may be questionable or improved. Results: We describe a continuous-index hidden Markov model for aCGH data as well as a Monte Carlo EM algorithm to estimate its parameters. It is shown that for a dataset from the BT-474 cell line analysed on 32K BAC tiling microarrays, this model yields considerably better model fit in terms of lag-1 residual autocorrelations compared to a discrete-index HMM, and it is also shown how to use the model for e.g. estimation of change points on the base-pair scale and for estimation of conditional state probabilities across the genome. In addition, the model is applied to the Glioblastoma Multiforme data used in the comparative study by Lai et al. (Lai,W.R. et al. (2005) Comparative analysis of algorithms for identifying amplifications and deletions in array CGH data. Bioinformatics, 21, 3763–3370.) giving result similar to theirs but with certain features highlighted in the continuous-index setting.

Evolution of 3D mobile games development
Authors: Fadi Chehimi, Paul Coulton, Reuben Edwards
Venue: Personal and Ubiquitous Computing (2008)

3D computer graphics have been an important feature in games development since it was first introduced in the early 80s and there is no doubt that 3D based content is often viewed as more attractive in games than the more abstract 2D graphics. Many games publishers are keen to leverage their success in the console market into the mobile phone platform. However, the resource constraints of mobile phones and the fragmented nature of the environment present considerable challenges for games developers. In this paper we consider some of the current constraints together with current and, probable, future developments both in the software and hardware of mobile phones. As part of this process we benchmark some of the latest and most prevalent software and hardware devices to ascertain both the quality of the graphics produced and the effects upon battery life. Whilst our test results highlight that the current market does indeed present challenges, our research into the future developments highlights the fact we are approaching greater standardization, which will be an important factor for the successful development of 3D mobile games.
A 40-ns 17-Bit by 17-Bit Array Multiplier
Authors: S. D. Pezaris
Venue: IEEE Transactions on Computers (1971)

A high-speed array multiplier generating the full 34-bit product of two 17-bit signed (2's complement) numbers in 40 ns is described. The multiplier uses a special 2-bit gated adder circuit with anticipated carry. Negative numbers are handled by considering their highest order bit as negative, all other bits as positive, and adding negative partial products directly through appropriate circuits. The propagation of sum and carry signals is such that sum delays do not significantly contribute to the overall multiplier delay.
