BISM: built-in self map for hybrid crossbar nano-architectures
Authors: Mehdi B. Tahoori
Venue: Proceedings of the 19th ACM Great Lakes symposium on VLSI (2009)

In hybrid nano architectures, self-assembled nanoscale crossbars are fabricated on top a reliable CMOS subsystem. Bottom-up selfassembly process used in the fabrication of nanoscale devices yields significantly more defects compared to the conventional top-down lithography used in CMOS fabrication. Therefore, applying defect tolerant design schemes is inevitable in order to map the design to these programmable fabrics by bypassing defects. In this paper, we present an alternative approach for defect tolerant mapping in which the mapping phase is built into the programmable fabric and reliable on-chip resources are used for on-the-fly defectfree mapping. This built-in self map (BISM) scheme significantly reduces the complexity of defect tolerance during design time as well as post-fabrication configuration time. Various BISMschemes are presented and their efficiencies in terms of defect tolerance and mapping time are compared.
Graph-Based Iterative Hybrid Feature Selection
Authors: ErHeng Zhong, Sihong Xie, Wei Fan, Jiangtao Ren, Jing Peng, Kun Zhang
Venue: Proceedings of the 2008 Eighth IEEE International Conference on Data Mining (2008)

When the number of labeled examples is limited, traditional supervised feature selection techniques often fail due to sample selection bias or unrepresentative sample problem. To solve this, semi-supervised feature selection techniques exploit the statistical information of both labeled and unlabeled examples in the same time. However, the results of semi-supervised feature selection can be at times unsatisfactory, and the culprit is on how to effectively use the unlabeled data. Quite different from both supervised and semi-supervised feature selection, we propose a “hybrid”framework based on graph models. We first apply supervised methods to select a small set of most critical features from the labeled data. Importantly, these initial features might otherwise be missed when selection is performed onthe labeled and unlabeled examples simultaneously. Next,this initial feature set is expanded and corrected with the use of unlabeled data. We formally analyze why the expected performance of the hybrid framework is better than both supervised and semi-supervised feature selection. Experimental results demonstrate that the proposed method outperforms both traditional supervised and state-of-the-art semisupervised feature selection algorithms by at least 10% inaccuracy on a number of text and biomedical problems with thousands of features to choose from. Software and dataset is available from the authors.
Adaptive bandwidth selection for biomarker discovery in mass spectrometry
Authors: Bernd Fischer, Volker Roth, Joachim M. Buhmann
Venue: Artificial Intelligence in Medicine (2009)

Objective: Differential quantification of proteins by liquid chromatography/mass spectrometry requires the alignment of a retention time axis. The alignment automatically corrects for time changes in the liquid chromatography unit when repeating two experiments. Methods: In this paper we will show an extension of non-negative canonical correlation analysis. We introduce an adaptive scale space estimation that adapts the complexity of a monotone regression function to the density of measurements across the retention time. Furthermore, a global model selection of the scale is replaced by a local one, where we estimate the scale for each individual time axis, instead of a global parameter that holds for all time axes. Results: We show in experiments that we got a 13% gain. The performance gain is measured in the number of proteins that are detected to differ significantly in abundance for two different biological samples. Conclusion: We conclude that the adaptive scale estimation and the local model selection can outperform the global model selection which yields a more effective selection of differentially abundant proteins.
Fluid analysis of an input control problem
Authors: Michael H. Veatch, Jonathan R. Senning
Venue: Queueing Systems: Theory and Applications (2009)

A two-station network with controllable inputs and sequencing control, proposed by Wein (Oper. Res. 38:1065---1078, 1990), is analyzed. A control is sought to minimize holding cost subject to a throughput constraint. In a Lagrangian formulation, input vanishes in the fluid limit. Several alternative fluid models, including workload formulations, are analyzed to develop a heuristic policy for the stochastic network. Both the fluid heuristic and Wein's diffusion solution are compared with the optimal policy by solving the dynamic program. Examples with up to six customer classes, using Poisson arrival and service processes, are presented. The fluid heuristic does well at sequencing control but the diffusion gives additional, and better, information on input control. The fluid analysis, in particular whether the fluid priorities are greedy, aids in determining whether the fluid heuristic contains useful information.
Predicting students' grades in computer science courses based on complexity measures of teacher's lecture notes
Authors: Kevin J. Keen, Letha Etzkorn
Venue: Journal of Computing Sciences in Colleges (2009)

In the past, predicting students grades has been done primarily by looking at students past test scores, at their history [1, 2], by looking at their current notes and/or their note taking ability [3, 5], from surveys about various other aspects of their background, or by a combination of such factors [4, 6, 7]. In this paper a different approach is taken -- here, the complexity of the teacher's lecture notes is examined as a predictor of the students' grades. The results of this research indicate that simple measures such as total number of words in the lecture or total number of lines of code that appear in the lecture are not good predictors of students' grades; however, "buzzword density," or the total number of words with Computer Science meaning divided by the total number of words in the lecture does predict students' grades.
A comparison study of IKE protocols
Authors: Ningning Lu, Huachun Zhou, Yajuan Qin
Venue: Proceedings of the International Conference on Mobile Technology, Applications, and Systems (2008)

The Internet key exchange (IKE) protocol is a protocol with which two communication peers can authenticate each other, get a new shared key and build IPSec SA. It has been widely used in mobile IPv6, router systems, IPv6 VPN and 3G core network elements. IKEv2 significantly improves the communication efficiency and security when compared with IKEv1. This article introduces the IKEv2's mechanism, particularly compares the security of IKEv1 and IKEv2.

Authors: Manfred Klopschitz, Dieter Schmalstieg
Venue: Proceedings of the 2007 6th IEEE and ACM International Symposium on Mixed and Augmented Reality (2007)

We present an approach towards automatic reconstruction of large assemblies of fiducial markers scattered throughout a wide indoor area, using a computer vision based reconstruction approach. The data is acquired from a video stream captured with a monoscopic camera. The system is capable of creating markers models that are significantly larger in physical area and number of markers than with previous approaches.
Semantic Web Service Composition for Service-Oriented Architectures
Authors: Thomas Weise, Steffen Bleul, Marc Kirchhoff, Kurt Geihs
Venue: Proceedings of the 2008 10th IEEE Conference on E-Commerce Technology and the Fifth IEEE Conference on Enterprise Computing, E-Commerce and E-Services (2008)

Semantic web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer works on a repository of services. The parameters of these services are semantically annotated in the same way as the parameters in the request. The composer then finds a set of services fulfilling the request -- the composition. If the input parameters given in the request are provided, the services of this set can be executed and will finally produce the wanted output parameters. In this paper, we introduce our new, improved composition system with which we will take part in the Web Service Challenge 2008.
Firmware engineering: methods and tools for firmware specification and design
Authors: Wolfgang K. Giloi, Reinhold Gueth, Bruce D. Shriver
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

Microprogramming has become the means of implementing the machine language instructions of a conventional computer. In the future, the vertical migration of functions from the software levels of a system to the microprogramming level may become equally important. The vertical migration of functions of a computer is undertaken to realize architectures having improved performance, functionality, reliability, or data security. The increased volume of microcode brought about by vertical migration tends to increase the complexity of the firmware development process and calls for a firmware engineering discipline that provides tools for the design and specification, implementation, validation, and maintenance of firmware. We present a rationale for the specification and procedural design of firmware based on the use of an appropriately defined specification language. The features of such a language and the supporting software system are outlined and demonstrated by the example of an existing APL-based firmware development system.
Structured software maintenance
Authors: G. R. Eugenia Schneider
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

Many books are written about structured design and programming, but never about structured maintenance. True structured maintenance comprises four functional roles, called the manager, librarian, archivist, and programmer. The manager manages. The archivist protects contents of computer files and stores information about these files in an archive library. The librarian organizes and stores software documentation in the form of a program documentation package. The programmer, of course, programs, using versions of the archive and library documents with slightly altered contents, and records day-to-day activities in the programmer's notebook. A special tool used by programmers is emergency takeover, which is a procedure for taking maintenance control of a new program.

Characterizing the exit process of a non-saturated IEEE 802.11 wireless network
Authors: Punit Rathod, Onkar Dabeer, Abhay Karandikar, Anirudha Sahoo
Venue: Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing (2009)

In this paper, we consider a non-saturated IEEE 802.11 based wireless network. We use a three-way fixed point to model the node behavior with Bernoulli packet arrivals and determine closed form expressions for the distribution of the time spent between two successful transmissions in an isolated network. The results of the analysis have been verified using extensive simulations in QualNet. The methodology presented in the paper is novel and we believe that the analysis like ours can be used as an approximation to model the behavior of sub-components of a larger mesh or hybrid network.

The purpose of this research is to develop an evaluation system for performing the initial evaluation, operational evaluation, and post evaluation of the collaborative information system that will support new product development of mould companies in KOREA. For these, we derived the CSFs and KPIs for evaluating the collaborative information system. And, the derived KPIs were applied to the design collaborative information system, which is the outcome of the e-Manufacturing project, and pre evaluation and post evaluation were conducted. Quantitative indexes were evaluated through the web-based evaluation system, whereas qualitative indexes can be evaluated through surveys.
Latent Dirichlet Allocation and Singular Value Decomposition Based Multi-document Summarization
Authors: Rachit Arora, Balaraman Ravindran
Venue: Proceedings of the 2008 Eighth IEEE International Conference on Data Mining (2008)

Multi-Document Summarization deals with computing a summary for a set of related articles such that they give the user a general view about the events. One of the objectives is that the sentences should cover the different events in the documents with the information covered in as few sentences as possible. Latent Dirichlet Allocation can breakdown these documents into different topics or events. However to reduce the common information content the sentences of the summary need to be orthogonal to each other since orthogonal vectors have the lowest possible similarity and correlation between them. Singular Value Decompositions used to get the orthogonal representations of vectors and representing sentences as vectors, we can get the sentences that are orthogonal to each other in the LDA mixture model weighted term domain. Thus using LDA we find the different topics in the documents and using SVD we find the sentences that best represent these topics. Finally we present the evaluation of the algorithms on the DUC2002 Corpus multi-document summarization tasks using the ROUGE evaluator to evaluate the summaries. Compared to DUC 2002 winners, our algorithms gave significantly better ROUGE-1 recall measures.

Authors: Javier Torrente, Ángel del Blanco, Guillermo Cañizal, Pablo Moreno-Ger, Baltasar Fernández-Manjón
Venue: Proceedings of the 2008 International Conference on Advances in Computer Entertainment Technology (2008)

Computer and videogames are rapidly entering the field of Technology-Enhanced Learning. Among the different approaches and game genres, adventure games have been pointed out as one of the most appropriate choices for education. Enthusiast instructors are looking for tools to develop their own educational games, but there are few tools for the rapid creation of modern adventure games with no programming background, and even fewer have been designed with educational gaming in mind. In this paper we present the <e-Adventure3D> platform, a complete environment for the creation and execution of 3D low-cost adventure games in educational contexts.
Conceptual simulation modeling: the structure of domain specific simulation environment
Authors: Kitti Setavoraphan, Floyd H. Grant
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

This study focuses on the development of a conceptual simulation modeling tool that can be used to structure a domain specific simulation environment. The issues in Software Engineering and Knowledge Engineering such as object-oriented concepts and knowledge representations are addressed to identify and analyze modeling frameworks and patterns of a specific problem domain. Thus, its structural and behavioral characteristics can be conceptualized and described in terms of simulation architecture and context. Moreover, symbols, notations, and diagrams are developed as a communication tool that creates a blueprint to be seen and recognized by both domain experts and simulation developers, which leads to the effectiveness and efficiency in the simulation development of any specific domains.

Authors: Yuxiang Wang, Xiuquan Qiao, Xiaofeng Li, Luoming Meng
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

The processing mechanism of service-context information is the foundation of personalized, intelligent services provision. This paper presented a Service Context Information Processing Mechanism Architecture (SCIPMA) based on "the laws of information transforms" in B3G/4G, and elaborated on its functional structure and technology realization. Based on the SCIPMA, we proposed the context-aware service provision framework in B3G/4G network. A new network entity-the context server that implemented the function of SCIPMA was inducted. Furthermore, an application example (the User-State Aware Communication System USACS) was developed and a series of experiments were conducted to verify the efficiency and applicability of SCIPMA. Finally, the results of experiments and evaluation of performance was demonstrated.
VEHICCLE: a model of web-based language learning
Authors: Anelly Kremenska
Venue: Proceedings of the 9th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing (2008)

This paper presents a model for Web-based language learning (VEHICCLE), which was developed to meet the needs of a growing number of specialists, lacking communicative competence when using a foreign language. It consists of modules (the process of learning) and assignments (the product of learning), embedded in a web-based learning environment. To exemplify the model, a working course is presented, and a scheme of application and evaluation of the model is proposed. Conclusions are drawn about the applicability of the model to creating courses in other languages and subjects and future work on evaluating the courses is suggested.
Data Availability in P2P Streaming Systems

Venue: Proceedings of the 2008 The Second International Conference on Next Generation Mobile Applications, Services, and Technologies (2008)

Nowadays, sharing multimedia contents in P2P systems has become a common practice. In general, it is done in "download" mode as any other type of data. However, due to their huge volume and real time constraint, multimedia data present another consumption mode which is the streaming mode. In this mode, rather than downloading the entire data before viewing it, it initiates a stream from the source peer to the destination one. The advantages of this mode are numerous such as latency reduction, copyright preservation (in the sense that the consumption peer does not hold the multimedia content), etc. Nevertheless, due to the unpredictable departure of peers and the real time constraint of the consumed data, the problem of maintaining data availability remains open. In this paper we propose to set up a cache to save the "last part" of the "now playing" videos. We demonstrate that such a cache can enhance the data availability in these systems while introducing an acceptable additional traffic. Additionally, we develop a cache management policy that automatically adapts the size of the cached data to the system workload. The simulations we conducted show the effectiveness of our approach.
Charge pump design for high-voltage biasing applications in piezoelectric-based miniaturized robots
Authors: A. Saiz-Vela, P. Miribel-Catala, J. Colomer, M. Puig-Vidal, J. Samitier
Venue: Analog Integrated Circuits and Signal Processing (2009)

Fully autonomous piezoelectric-based miniaturized robots usually have a high-voltage biasing system that provides the required voltage levels to drive properly their piezoelectric actuators. In this paper a novel on-board biasing system based on the cascade connection of three full-custom charge pump ICs is presented. Simulated and experimental results show that the proposed biasing system is capable to obtain a regulated output voltage up to 20 V from a 3.3 V battery and deliver successfully up to 120 mW of power. Moreover, a novel approach in the steady-state analysis of the two-phase voltage doubler (which is the core of the designed charge pump IC) has been developed in order to have a tool capable to provide a full understanding of the steady-state voltage doubler's behavior while at the same time accelerate and simplify the design process of such circuit. Simulated results show that the proposed mathematical model is more accurate than already developed models. The design of the charge pump IC has been implemented using a commercial 0.7 μm Bipolar-CMOS-DMOS (BCD) technology.
The design and implementation of a new UNIX kernel
Authors: Charles Crowley
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

A project to produce a kernel-based, message-passing version of UNIX is described. The system is designed to be (1) useful in teaching operating systems, (2) easily changeable, (3) easily portable, and (4) a vehicle for studying the message-passing approach to operating systems design. The system calls normally handled by the UNIX kernel are handled by system processes, each of which operates in its own address space. Interprocess communication and process environment management is done by a small kernel. The design and implementation of the system are described. Message passing as a system design method is evaluated in this context and compared with the procedure call orientation of standard UNIX. The message-based design proved successful in creating a modular and understandable system.
