A control theory approach for thermal balancing of MPSoC
Authors: Francesco Zanini, David Atienza, Giovanni De Micheli
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

Thermal balancing and reducing hot-spots are two important challenges facing the MPSoC designers. In this work, we model the thermal behavior of a MPSoC as a control theory problem which enables the design of an optimum frequency controller without depending on the thermal profile of the chip. The optimization performed by the controller is targeted to achieve thermal balancing on the MPSoC thermal profile to avoid hotspots and improve its reliability. The proposed system is able to perform an on-line minimization of chip thermal gradients based on both scheduler requirements and the chip thermal profile. We compare this with state of the art thermal management approaches. Our comparison shows that the proposed system offers a better both thermal profile (temperature differences higher than 4&deg; C have been reduced from 27.9% to 0.45%) and performance (up to 32% task waiting time reduction).
Leader election algorithm using heap structure
Authors: M. Sepehri, M. Goodarzi
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

Several distributed algorithms require that there be a coordinator process in the entire system. Since all other processes in the system have to interact with the coordinator, they all must agree on who the coordinator is. Furthermore, if the coordinator process fails due to the failure of the site on which it is located, a new coordinator process must be elected to take up the job of the failed coordinator. Election algorithms are meant for electing a coordinator among currently running processes. This paper deals with the distributed leader election algorithm for a set of processes connected by a tree network. In this paper, we propose a linear time algorithm for leader election using heap structure and describe it in details.
Managing Large Scale Broadband Multimedia Services on Distributed Media Servers
Authors: Reinhard Luling
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

This paper presents algorithms and principles for the management of large scale broadband multimedia services. For the implementation of these services we use a network of distributed media servers, storing broadband media information e.g. audio and video that are streamed from the server to the connected clients.The problem studied in this paper is the managing of media content on a server network. We present the "Distributed Server Management System (DSMS)" that performs an efficient content and service management on the distributed servers. The DSMS allows to collect access patterns from the users of the multimedia services and uses this knowledge for the solution of some combinatorial optimization algorithms that have to be solved for an efficient assignment of media assets. We present these optimization algorithms and evaluate their performance using some benchmark instances.

Power and performance management of virtualized computing environments via lookahead control
Authors: Dara Kusic, Jeffrey O. Kephart, James E. Hanson, Nagarajan Kandasamy, Guofei Jiang
Venue: Cluster Computing (2009)

There is growing incentive to reduce the power consumed by large-scale data centers that host online services such as banking, retail commerce, and gaming. Virtualization is a promising approach to consolidating multiple online services onto a smaller number of computing resources. A virtualized server environment allows computing resources to be shared among multiple performance-isolated platforms called virtual machines. By dynamically provisioning virtual machines, consolidating the workload, and turning servers on and off as needed, data center operators can maintain the desired quality-of-service (QoS) while achieving higher server utilization and energy efficiency. We implement and validate a dynamic resource provisioning framework for virtualized server environments wherein the provisioning problem is posed as one of sequential optimization under uncertainty and solved using a lookahead control scheme. The proposed approach accounts for the switching costs incurred while provisioning virtual machines and explicitly encodes the corresponding risk in the optimization problem. Experiments using the Trade6 enterprise application show that a server cluster managed by the controller conserves, on average, 22% of the power required by a system without dynamic control while still maintaining QoS goals. Finally, we use trace-based simulations to analyze controller performance on server clusters larger than our testbed, and show how concepts from approximation theory can be used to further reduce the computational burden of controlling large systems.

The design and evaluation of multi-finger mouse emulation techniques
Authors: Justin Matejka, Tovi Grossman, Jessica Lo, George Fitzmaurice
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

We explore the use of multi-finger input to emulate full mouse functionality, such as the tracking state, three buttons, and chording. We first present the design space for such techniques, which serves as a guide for the systematic investigation of possible solutions. We then perform a series of pilot studies to come up with recommendations for the various aspects of the design space. These pilot studies allow us to arrive at a recommended technique, the SDMouse. In a formal study, the SDMouse was shown to significantly improve performance in comparison to previously developed mouse emulation techniques.
Using role play for an upper level CS course
Authors: Michael Leverington, Murat Yüksel, Michael Robinson
Venue: Journal of Computing Sciences in Colleges (2009)

This paper reports on initial experiences with using role play interaction in an upper level operating systems (OS) course. Three role play scenarios were implemented related to multi-programming, concurrency and synchronization, and a culminating experience that included several OS transactions with emphasis on input and output (I/O) operations. Students reported better understanding of the concepts, and stated appreciation for the chance to see some of the abstracted components made more concrete. The activities are discussed, the initial student feedback is provided, and future plans for improvement and further implementation of these and other scenarios in the future are briefly presented.
Needs and trends in embedded software development for consumer electronics
Authors: Yasutaka Tsunakawa
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

Like other domains, the flow to Many-Core can not be avoided in the domain of the consumer electronics either. The Multi-Core has already become the mainstream of the system LSI, and the number of cores in the chip will continue to increase. Because of the advancement of required functions and the pressure to the consumption electricity reduction, the flow to Many-Core will continue without cessation. However, seeing it from a point of view of the embedded software development, there are many unsolved problems that lie like a huge cliff between the current Multi-Core and Many-Core. The research organizations seem to make their main efforts in technical establishment of Many-Core, and the tool vendors concentrates on a solution offer to the current Multi-Core. Therefore measures of the transition period will come several years later are still insufficient. In this article, I want to discuss about the major issues which block the shift to Many-Core from the current Multi-Core, from the viewpoint of consumer electronics.
A family of interface elements for the analysis of composite beams with interlayer slip
Authors: Amilton R. da Silva, João Batista M. Sousa Jr.
Venue: Finite Elements in Analysis and Design (2009)

This work presents the numerical formulation of a family of zero-thickness interface elements developed for the simulation of composite beams with horizontal deformable connection, or interlayer slip. The proposed elements include formulations to be employed with Euler-Bernoulli as well as with Timoshenko beam theories, combined to displacement-based beam elements sharing the same degrees of freedom. The elements may be employed for the simulation of steel-concrete composite beams, layered beams or other structural systems in which components are connected with the possibility of interlayer slip. Numerical examples are provided to assess the accuracy and robustness of the formulations and to identify the most reliable formulations. Abnormal slip distributions are shown to occur also with the Timoshenko-based elements, usually in conjunction with transverse shear locking.

Towards e-governance: a case study of employees provident fund of Nepal
Authors: Deepak Rauniar, Radha Krishna Pote
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

The effective use of Information and Communication Technologies (ICT) services in government administration can greatly enhance existing efficiencies, drive down communication costs, and increase transparency. Karmachari Sanchaya Kosh (KSK) or the Employees Provident Fund (EPF) in English, is a Public Sector Enterprise (PSE) in Nepal that provides social security benefits to its member contributors on behalf of Nepal government. In a country, where the bureaucratic system has been quite slow to adopt ICT and reap its benefits, KSK stands distinctly apart. It is often cited as an example of one of the few government agencies in Nepal which has succeeded in taking forward the computerization agenda and progress towards e-governance. In this case study, we review the same.
The attentional blink reveals serial working memory encoding: Evidence from virtual and human event-related potentials
Authors: Patrick Craston, Brad Wyble, Srivas Chennu, Howard Bowman
Venue: Journal of Cognitive Neuroscience (2009)

Observers often miss a second target (T2) if it follows an identified first target item (T1) within half a second in rapid serial visual presentation (RSVP), a finding termed the attentional blink. If two targets are presented in immediate succession, however, accuracy is excellent (Lag 1 sparing). The resource sharing hypothesis proposes a dynamic distribution of resources over a time span of up to 600 msec during the attentional blink. In contrast, the ST2 model argues that working memory encoding is serial during the attentional blink and that, due to joint consolidation, Lag 1 is the only case where resources are shared. Experiment 1 investigates the P3 ERP component evoked by targets in RSVP. The results suggest that, in this context, P3 amplitude is an indication of bottom-up strength rather than a measure of cognitive resource allocation. Experiment 2, employing a two-target paradigm, suggests that T1 consolidation is not affected by the presentation of T2 during the attentional blink. However, if targets are presented in immediate succession (Lag 1 sparing), they are jointly encoded into working memory. We use the ST2 model's neural network implementation, which replicates a range of behavioral results related to the attentional blink, to generate "virtual ERPs" by summing across activation traces. We compare virtual to human ERPs and show how the results suggest a serial nature of working memory encoding as implied by the ST2 model.

Improved Randomized Online Scheduling of Unit Length Intervals and Jobs
Authors: Stanley P. Fung, Chung Keung Poon, Feifeng Zheng
Venue: Approximation and Online Algorithms: 6th International Workshop, WAOA 2008, Karlsruhe, Germany, September 18-19, 2008. Revised Papers (2009)

We study the online interval scheduling problem and the online job scheduling problem (with restart). In both problems, the intervals or jobs have unit length and arbitrary weights, and the objective is to maximize the total weight of completed intervals (or jobs). We first gave a 2-competitive randomized algorithm for the case of intervals. The algorithm is barely random in the sense that it randomly chooses between two deterministic algorithms at the beginning and then sticks with it thereafter. The algorithm is surprisingly simple and improves upon several previous results. Then we extended the algorithm to the scheduling of jobs with restarts, and proved that it is 3-competitive. We also proved a lower bound of 2 on the competitive ratio of all barely random algorithms that choose between two deterministic algorithms for scheduling intervals (and jobs).
Effects of HIV-1 Proteins on the Fas-Mediated Apoptotic Signaling Cascade: A Computational Study of Latent CD4+ T Cell Activation
Authors: John Jack, Andrei Păun, Alfonso Rodríguez-Patón
Venue: Membrane Computing: 9th International Workshop, WMC 2008, Edinburgh, UK, July 28-31, 2008, Revised Selected and Invited Papers (2009)

We present a new model for simulating Fas-induced apoptosis in HIV-1-infected CD4+ T cells. Moreover, the reactivation of latently infected cells is explored. The work, an extension of our previous modeling efforts, is the first attempt in systems biology for modeling the Fas pathway in the latently infected cells. These enigmatic cells are considered the last barrier in the elimination of HIV infection. In building the model, we gathered what reaction rates and initial conditions are available from the literature. For the unknown constants, we fit the model to the available information on the observed effects of HIV-1 proteins in activated CD4+ T cells. We provide results, using the Nondeterministic Waiting Time (NWT) algorithm, from the model, simulating the infection of activated CD4+ T cells as well as the reactivation of a latently infected cells. These two model versions are distinct with respect to the initial conditions --- multiplicities and locations of proteins at the beginning of the simulation.

We give an overview of a drawing approach that combines the concepts constraint satisfaction, attribute evaluation and transformation. The approach is tailored to an editor for visual languages, which supports structured editing as well as free-hand editing. In this paper, we focus on the visual specification of such a layout algorithm. As a running example, deterministic finite automata are used.
Miniaturized extended-stopband microstrip ring resonator bandpass filter using uniplanar compact photonic bandgap (UC-PBG) structures
Authors: Heba B. El-Shaarawy, Fabio Coccetti, Robert Plana, Mostafa El-Said, Essam A. Hashish
Venue: Proceedings of the 8th conference on Applied informatics and communications (2008)

This paper addresses a modified bandpass ring resonator filter providing compact size, low insertion-loss, wide bandwidth, sharp rejection and suppressed higher order modes. The filter enhancement follows a threefold approach. First, UC-PBG structures are used to suppress the higher order passbands yielding an upper stopband that reaches 4.7 GHz, beside offering a further advantage in terms of size reduction. Second, the use of internal folded stubs allows the exploitation of the internal area of the ring resonator, which translates into an overall size reduction of 84.5%. Finally, a solution employing via holes to replace the tuning stubs is explored in order to extend the lower stopband. EM simulation, equivalent circuit model, as well as measurement results validate the followed design approach and are in excellent agreement within each other.

MMOHILS: a simpler approach to valid agents in human simulation studies
Authors: Seth N. Hetu, Gary Tan
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

A novel technique for accurately and inexpensively simulating large numbers of people is introduced: Massively Multiplayer Online Human In the Loop Simulation (MMOHILS). This technique is applicable to certain simulations which would normally use AI-based agents to model human behavior, and its validation techniques are substantially simpler. A prototype for two types of MMOHILS (experimental and unannounced) is laid forth in this paper, with examples given from a current prototype in development for use in egress analysis.
