Bayesian analysis of constant elasticity of variance models: Research Articles
Authors: Jennifer S. K. Chan, S. T. Boris Choy, Anna B. W. Lee
Venue: Applied Stochastic Models in Business and Industry (2007)

This paper focuses on the estimation of some models in finance and in particular, in interest rates. We analyse discretized versions of the constant elasticity of variance (CEV) models where the normal law showing up in the usual discretization of the diffusion part is replaced by a range of heavy-tailed distributions. A further extension of the model is to allow the elasticity of variance to be a parameter itself. This generalized model allows great flexibility in modelling and simplifies the model implementation considerably using the scale mixtures representation. The mixing parameters provide a means to identify possible outliers and protect inference by down-weighting the distorting effects of these outliers. For parameter estimation, Bayesian approach is adopted and implemented using the software WinBUGS (Bayesian inference using Gibbs sampler). Results from a real data analysis show that an exponential power distribution with a random shape parameter, which is highly leptokurtic compared with the normal distribution, forms the best CEV model for the data.

Efficient simulation for risk measurement in portfolio of CDOS
Authors: Michael Gordy, Sandeep Juneja
Venue: Proceedings of the 38th conference on Winter simulation (2006)

We consider a portfolio containing CDO tranches as well as ordinary bonds. Our interest is in large loss probabilities and risk measures such as value-at-risk. When loss is measured on a mark-to-market basis, estimation via simulation requires a nested procedure: In the outer step one draws realizations of all risk factors up to the horizon, and in the inner step one re-prices each instrument in the portfolio at the horizon conditional on the drawn risk factors. Practitioners perceive the computational burden of such nested schemes to be unacceptable, and adopt a variety of somewhat ad hoc measures to avoid the inner simulation. In this paper, we question whether such short cuts are necessary. We show that a relatively small number of trials in the inner step can yield accurate estimates, and analyze how a fixed computational budget may be allocated to the inner and the outer step to minimize the mean square error of the resultant estimator.

Modeling ice dynamics as a thin-film Stefan problem
Authors: Theodore Kim, David Adalsteinsson, Ming C. Lin
Venue: Proceedings of the 2006 ACM SIGGRAPH/Eurographics symposium on Computer animation (2006)

Large, 3D ice formations such as icicles exhibit a high degree of geometric and optical complexity. Modeling these features by hand can be a daunting task, so we present a novel physically-based algorithm for simulating this phenomenon. Solidification is usually posed as a so-called 'Stefan problem', but the problem in its classic form is inappropriate for simulating the ice typically found in a winter scene. We instead use the 'thin-film' variant of the Stefan problem to derive velocity equations for a level set simulation. However, due to the scales involved in the problem, even an adaptive grid level set solver is still insufficient to track the tip of an icicle. Therefore, we derive an analytical solution for the icicle tip and use it to correct the level set simulation. The results appear to be in agreement with experimental data. We also present a physically-based technique for modeling ripples along the ice surface that alleviates the need to explicitly track small-scale geometry. To our knowledge, our approach is the most complete model available, and produces complex visual phenomena that no previous method has been able to capture.
High aspect ratio tapered hollow metallic microneedle arrays with microfluidic interconnector
Authors: Kabseog Kim, Jeong-Bong Lee
Venue: Microsystem Technologies (2006)

We present a novel microfabrication method for a tapered hollow metallic microneedle array and its complete microfluidic packaging for drug delivery and body fluid sampling applications. Backside exposure of SU-8 through a UV transparent substrate was investigated as a means of fabricating a dense array of tall (up to 400&#x00a0;&#x03bc;m) uniformly tapered SU-8 pillar structures with angles in the range of 3.1&#x2013;5&#x00b0; on top of the SU-8 mesa. Conformal electroplating of metals on top of the array of the tapered SU-8 pillars, lapping of the tip of the metallic microneedles with planarizing polymer, and removal of the SU-8 sacrificial layers resulted in an array of tapered hollow metallic microneedles with a fluidic reservoir on the backside. A microfluidic interconnector assembly was designed and fabricated using SU-8 and conventionally machined PMMA in a way that it has a male interconnector, which directly fits into the fluidic reservoir of the microneedle array at one end and the other male interconnector, which provides fluidic interconnection to external devices at the other end. The fluid flow rate was measured and it showed 0.69&#x00a0;&#x03bc;L/s. per microneedle when the pressure of 6.89&#x00a0;KPa (1&#x00a0;psi) was applied.
Deciding the financial health of dot-coms using rough sets
Authors: Indranil Bose
Venue: Information and Management (2006)

We conducted an empirical investigation of dot-coms from a financial perspective. Data from the financial statements of 240 such businesses was used to compute financial ratios and the rough sets technique was used to evaluate whether the financial ratios could predict financial health of them based on available data. The most predictive financial ratios were identified and interesting rules concerning the financial ratios and financial health of dot-coms were discovered. It was shown that rough sets performed a satisfactory job of predicting financial health and were more suitable for detecting unhealthy dot-coms than healthy ones.
Analysis of binding site similarity, small-molecule similarity and experimental binding profiles in the human cytosolic sulfotransferase family
Authors: Rafael J. Najmanovich, Abdellah Allali-Hassani, Richard J. Morris, Ludmila Dombrovsky, Patricia W. Pan, Masoud Vedadi, Alexander N. Plotnikov, Aled Edwards, Cheryl Arrowsmith, Janet M. Thornton
Venue: Bioinformatics (2007)

Motivation: In the present work we combine computational analysis and experimental data to explore the extent to which binding site similarities between members of the human cytosolic sulfotransferase family correlate with small-molecule binding profiles. Conversely, from a small-molecule point of view, we explore the extent to which structural similarities between small molecules correlate to protein binding profiles. Results: The comparison of binding site structural similarities and small-molecule binding profiles shows that proteins with similar small-molecule binding profiles tend to have a higher degree of binding site similarity but the latter is not sufficient to predict small-molecule binding patterns, highlighting the difficulty of predicting small-molecule binding patterns from sequence or structure. Likewise, from a small-molecule perspective, small molecules with similar protein binding profiles tend to be topologically similar but topological similarity is not sufficient to predict their protein binding patterns. These observations have important consequences for function prediction and drug design. Contact: rafael.najmanovich@ebi.ac.uk
SU-8: promising resist for advanced direct LIGA applications for high aspect ratio mechanical microparts
Authors: J. Kouba, R. Engelke, M. Bednarzik, G. Ahrens, Heinz-Ulrich Scheunemann, G. Gruetzner, B. Loechel, H. Miller, D. Haase
Venue: Microsystem Technologies (2006)

A case study of use of negative type SU-8 X-ray sensitive resist for fabrication of advanced, highly precise, ultra tall direct LIGA mechanical microparts is presented in this paper. Using direct LIGA technique, &#x223c;1&#x00a0;mm tall highly precise metallic gear wheels are being fabricated, previously using PMMA based process. Starting from a non-optimized non-satisfying SU-8 process, significant process parameters for process optimization were identified using statistical design of experiment. By varying the significant process parameters, SU-8 process was further optimized with respect to critical aspect of sidewall bow and tilt of metallic structures. After the optimization, metallic parts fabricated using SU-8 process showed comparable quality as those fabricated using PMMA based process.
The Clustered AGgregation (CAG) technique leveraging spatial and temporal correlations in wireless sensor networks
Authors: Sunhee Yoon, Cyrus Shahabi
Venue: ACM Transactions on Sensor Networks (TOSN) (2007)

Sensed data in Wireless Sensor Networks (WSN) reflect the spatial and temporal correlations of physical attributes existing intrinsically in the environment. In this article, we present the Clustered AGgregation (CAG) algorithm that forms clusters of nodes sensing similar values within a given threshold (spatial correlation), and these clusters remain unchanged as long as the sensor values stay within a threshold over time (temporal correlation). With CAG, only one sensor reading per cluster is transmitted whereas with Tiny AGgregation (TAG) all the nodes in the network transmit the sensor readings. Thus, CAG provides energy efficient and approximate aggregation results with small and often negligible and bounded error. In this article we extend our initial work in CAG in five directions: First, we investigate the effectiveness of CAG that exploits the temporal as well as spatial correlations using both the measured and modeled data. Second, we design CAG for two modes of operation (interactive and streaming) to enable CAG to be used in different environments and for different purposes. Interactive mode provides mechanisms for one-shot queries, whereas the streaming mode provides those for continuous queries. Third, we propose a fixed range clustering method, which makes the performance of our system independent of the magnitude of the sensor readings and the network topology. Fourth, using mica2 motes, we perform a large-scale measurement of real environmental data (temperature and light, both indoor and outdoor) and the wireless radio reliability, which were used for both analytical modeling and simulation experiments. Fifth, we model the spatially correlated data using the properties of our real world measurements. Our experimental results show that when we compute the average of sensor readings in the network using the CAG interactive mode with the user-provided error threshold of, 20&percnt;, we can save 68.25&percnt; of transmissions over TAG with only 2.46&percnt; inaccuracy in the result. The streaming mode of CAG can save even more transmissions (up to 70.24&percnt; in our experiments) over TAG, when data shows high spatial and temporal correlations. We expect these results to hold in reality, because we used the mica2 radio profile and empirical datasets for our simulation study. CAG is the first system that leverages spatial and temporal correlations to improve energy efficiency of in-network aggregation. This study analytically and empirically validates CAG's effectiveness.
Effective Software Project Management
Authors: Robert K. Wysocki
Venue:  (2006)

Why another book on software project management? For some time, the fields of project management, computer science, and software development have been growing rapidly and concurrently. Effective support for the enterprise demands the merging of these efforts into a coordinated discipline, one that incorporates best practices from both systems development and project management life cycles. Robert K. Wysocki creates that discipline in this book--a ready reference for professionals and consultants as well as a textbook for students of computer information systems and project management. By their very nature, software projects defy a "one size fits all" approach. In these pages you will learn to apply best-practice principles while maintaining the flexibility that's essential for successful software development. Learn how to make the planning process fit the need * Understand how and why software development must be planned on a certainty-to-uncertainty continuum * Categorize your projects on a four-quadrant model * Learn when to use each of the five SDPM strategies--Linear, Incremental, Iterative, Adaptive, and Extreme * Explore the benefits of each strategic model and what types of projects it supports best * Recognize the activities that go into the Scoping, Planning, Launching, Monitoring/Controlling, and Closing phases of each strategy * Apply this knowledge to the specific projects you manage * Get a clear picture of where you are and how to get where you want to go
Bridging the gap between principles and practices in microprogramming
Authors: David Cohen, Ming T. Liu
Venue: ACM SIGMICRO Newsletter (1976)

The concept of microprogramming was introduced by Wilkes [WILKM51] a quarter of a century ago, but it took more than a decade of technological developments (the advent of low-cost, high-speed ROS) to bring it to the stage of an applied concept [HUSSS70]. The interest in microprogramming has increased markedly during the past years with the introduction of the low-cost, high-density LSI memory chips. Current trends in microprogramming include user microprogrammable systems, high-level language interpreters, operating systems, microprocessors, and special applications [JONEL74, FLYNM75, JONEL75, AGRAA76]. Although microprogramming has been widely accepted as a valid approach to the design of computer systems, it is still practiced by a limited number of professionals only, due to the cloak of secrecy held over this technology by major computer manufacturers [JONEL74]. The position of microprogramming in the computer science and engineering curriculum remains obscure [MULDM75]. We feel that this is partially due to the problem in teaching about microprogramming. Currently there does not exist a well established theory of microprogramming and therefore most technical articles on this subject are based on examples and case studies. The three books on microprogramming [HUSSS70, AGRAA76, SALIA76] are satisfactory in providing a set of basic principles and many case studies, but difficulties in understanding are encountered when a specific system is introduced with all its software, firmware and hardware complexity. The student can identify the major elements, but finds it difficult (in many cases impossible) to understand how the basic principles have been transformed into the results displayed before him. Existing literature rarely covers the design objectives and the design tradeoffs which in fact determine the final product of an implemented computer system (a good example is [BUCHW62]). As a result of this situation, we have experienced a serious difficulty in our effort to close the gap between understanding the basic principles and the ability to absorb the characteristics of existing systems.
Dynamic routing to heterogeneous collections of unreliable servers
Authors: K. D. Glazebrook, C. Kirkbride
Venue: Queueing Systems: Theory and Applications (2007)

We argue the importance of problems concerning the dynamic routing of tasks for service in environments where the servers have diverse characteristics and are subject to breakdown. We propose a general model in which both service times and repair times at each machine are i.i.d.with some general distribution. Routing decisions take account of queue lengths, machine states (up or down), the elapsed processing times of jobs in service and the times to date of any machine repairs in progress. We develop an approach to machine calibration which yields a machine index which is a function of all of the preceding information. The heuristic which routes all tasks to the machine of current smallest index performs outstandingly well. The approach of the paper is flexible and is capable of yielding strongly performing routing policies for a range of variants of the basic model. These include cases where job processing is lost at each breakdown and where the machine state may be only partially observed.
Approaches to complexity reduction in a systems biology research environment (SYCAMORE)
Authors: Irina Surovtsova, Sven Sahle, Jürgen Pahle, Ursula Kummer
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Due to the complexity of biochemical reaction networks, so-called complexity reduction algorithms play a crucial role for making simulations efficient and for dissecting biochemical networks into meaningful subnetworks for analysis. Here, different approaches are presented, which we are developing in the context of a computational research environment for systems biology (SYCAMORE). These approaches are based on time-scale decomposition, sensitivity analysis, and hybrid simulation methods.
An Efficient Pipeline Architecture for Deblocking Filter in H.264/AVC
Authors: Chung-Ming Chen, Chung-Ho Chen
Venue: IEICE - Transactions on Information and Systems (2007)

In this paper, we study and analyze the computational complexity of deblocking filter in H.264/AVC baseline decoder based on SimpleScalar/ARM simulator. The simulation result shows that the memory reference, content activity check operations, and filter operations are known to be very time consuming in the decoder of this new video coding standard. In order to improve overall system performance, we propose a novel processing order with efficient VLSI architecture which simultaneously processes the horizontal filtering of vertical edge and vertical filtering of horizontal edge. As a result, the memory performance of the proposed architecture is improved by four times when compared to the software implementation. Moreover, the system performance of our design significantly outperforms the previous proposals.
