Bandwidth reservation using WLAN handoff prediction
Authors: Libo Song, Udayan Deshpande, Ulas Kozat, David Kotz, Ravi Jain
Venue: ACM SIGMOBILE Mobile Computing and Communications Review (2006)

Many network services may be improved or enabled by successful predictions of users' future mobility. The success of predictions depend on how much accuracy can be achieved on real data and on the sensitivity of particular applications to this achievable accuracy. We investigate these issues for the case of advanced bandwidth reservation using real WLAN traces collected on the Dartmouth College campus [1].
Conceptual modeling for simulation: issues and research requirements
Authors: Stewart Robinson
Venue: Proceedings of the 38th conference on Winter simulation (2006)

It is generally recognized that conceptual modeling is one of the most vital parts of a simulation study. At the same time, it also seems to be one of the least understood. A review of the extant literature on conceptual modeling reveals a range of issues that need to be addressed: the definition of conceptual model(ling), conceptual model requirements, how to develop a conceptual model, conceptual model representation and communication, conceptual model validation, and teaching conceptual modeling. It is clear that this is an area ripe for further research, for the clarification of ideas and the development of new approaches. Some areas in which further research could be carried out are identified.
LSODE and LSODI, two new initial value ordinary differnetial equation solvers
Authors: Alan C. Hindmarsh
Venue: ACM SIGNUM Newsletter (1980)

Two new packages are available for the numerical solution of the initial value problem for stiff and nonstiff systems of ordinary differntial equations (ODE's). LSODE solves explicitly given ODE systems, while LSODI solves systems given in linearly implicit form, including differential-algebraic systems. Both are based on older packages that have proved highly popular, but both reflect a wide variety of improvements in the design of the user interface, algorithms, and program structure.
Restarting automata with restricted utilization of auxiliary symbols
Authors: Tomasz Jurdzinski, Friedrich Otto
Venue: Theoretical Computer Science (2006)

The restarting automaton is a restricted model of computation that was introduced by Jančar et al. to model the so-called analysis by reduction, which is a technique used in linguistics to analyse sentences of natural languages. The most general models of restarting automata make use of auxiliary symbols in their rewrite operations, although this ability does not directly correspond to any aspect of the analysis by reduction. Here we put restrictions on the way in which restarting automata use auxiliary symbols, and we investigate the influence of these restrictions on their expressive power. In fact, we consider two types of restrictions. First, we consider the number of auxiliary symbols in the tape alphabet of a restarting automaton as a measure of its descriptional complexity. Secondly, we consider the number of occurrences of auxiliary symbols on the tape as a dynamic complexity measure. We establish some lower and upper bounds with respect to these complexity measures concerning the ability of restarting automata to recognize the (deterministic) context-free languages and some of their subclasses.

Generating compact representations of static scenes by means of 3D object hierarchies
Authors: Angel Domingo Sappa, Miguel Angel Garcia
Venue: The Visual Computer: International Journal of Computer Graphics (2007)

This paper presents a new heuristic algorithm for computing a compact hierarchical representation of the objects contained in a 3D static scene. The algorithm first builds a fully-connected adjacency graph that keeps the costs of grouping the different pairs of objects of the scene. Afterward, the graph&#x2019;s minimum spanning tree is computed and its edges sorted in ascending order according to their cost. Next, from that sorted list, a cost-based clustering technique is applied, thus generating new objects at a higher level in the hierarchy. A new object can be defined after merging two or more objects according to their corresponding linking costs. The algorithm starts over by generating a new adjacency graph from those new objects, along with the objects that could not be merged before. The iterative process is applied until an adjacency graph with a single object is obtained. The latter is the root of the hierarchical representation. Balance and coherence of the hierarchy, in which spatially close objects are also structurally close, is achieved by defining an appropriate cost function. The proposed technique is evaluated upon several 3D scenes and compared to a previous technique. In addition, the benefits of the proposed technique with respect to techniques based on octrees and kd-trees are analyzed in terms of a practical application.
A PERT-CPM tutorial
Authors: H. S. Swanson, R. E. D. Woolsey
Venue: Issue 16 (April 1974) (1974)

PERT and CPM, acronyms for "program evaluation and review technique" and "critical path method", respectively, are network techniques used to aid in the planning, scheduling, monitoring, and control of activities which are related to each other. For example, CPM is frequently used in the construction industry to help organize and schedule those activities which together constitute a given construction project. PERT was first used to help coordinate the activities in the development of the Polaris missle system. PERT and CPM differ from each other in that activity times are handled differently by these two closely related techniques. In using CPM, one assumes the activity times are known with certainty (deterministic activity times); PERT allows for uncertainty and statistical variation in activity times (stochastic activity times). Never the less, PERT and CPM are closely related (CPM may be a special case of PERT), and a variety of projects are subject to analysis by either technique:(1)(1) construction projects(2) planning and launching a new product(3) a turn around in an oil refinery (or other maintenance projects)(4) installing and debugging a computer system(5) scheduling ship construction and repairs(6) manufacture and assembly of large job-lot operations(7) missile countdown procedures(8) end-of-the month closing of accounting records(9) research and development projects

Palmprint identification using feature-level fusion
Authors: Adams Kong, David Zhang, Mohamed Kamel
Venue: Pattern Recognition (2006)

In this paper, we propose a feature-level fusion approach for improving the efficiency of palmprint identification. Multiple elliptical Gabor filters with different orientations are employed to extract the phase information on a palmprint image, which is then merged according to a fusion rule to produce a single feature called the Fusion Code. The similarity of two Fusion Codes is measured by their normalized hamming distance. A dynamic threshold is used for the final decisions. A database containing 9599 palmprint images from 488 different palms is used to validate the performance of the proposed method. Comparing our previous non-fusion approach and the proposed method, improvement in verification and identification are ensured.

SU-8 3D microoptic components fabricated by inclined UV lithography in water
Authors: Z. Ling, K. Lian
Venue: Microsystem Technologies (2006)

Out-of-plane microlenses and microoptical fiber holder are two of the most important components for building an integrated microoptic system with a precise alignment accuracy. In this paper, a simple and convenient method to fabricate these components from SU-8 by using inclined UV lithography in water is proposed. It consists of two perpendicular exposures in SU-8 at &#x00b1;45&#x00b0;. DI water possesses a low absorption coefficient and a moderate and stable value of refractive index in near UV. Using water, the exposure angle in SU-8 can be increased to 50&#x00b0; from 35&#x00b0; in air necessary to pattern the desired 45&#x00b0; slope of the sidewalls. The principle of the proposed technique and the detailed fabrication process of the microoptic components will be presented. The integratability of the fabricated components was demonstrated by the fabrication of the microoptical fiber holder with a pre-aligned out-of-plane microlens.

Optical networks must meet the challenge of supporting multiple types of transmissions including voice, video, and data traffic. Although time-division multiplexing (TDM) has provided a growth path for services, it is more constrained than IP + Optical strategies like the Cisco Dynamic Packet Transport (Resilient Packet Ring). The Cisco Systems® end-to-end IP + Optical networking strategy provides an intelligent converged network in which optical infrastructures can be used to their fullest potential.While most reference books focus on the theory involved in SONET and optical infrastructures, Cisco Self-Study: Building Cisco Metro Optical Networks (METRO) focuses on the practical application of planning and configuring optical networks that involve SONET, DWDM, Metropolitan Ethernet, Packet over SONET, and Dynamic Packet Transport (Resilient Packet Ring).Cisco Self-Study: Building Cisco Metro Optical Networks (METRO) is part of a recommended learning path from Cisco Systems that can include simulation and hands-on training from authorized Cisco Learning Partners and self-study products from Cisco Press.

A hybrid method for simulation factor screening
Authors: Hua Shen, Hong Wan
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Factor screening is performed to eliminate unimportant factors so that the remaining important factors can be more thoroughly studied in later experiments. Controlled Sequential Bifurcation (CSB) and Controlled Sequential Factorial Design (CSFD) are two new screening methods for discrete-event simulations. Both methods use hypothesis testing procedures to control the Type I Error and power of the screening results. The scenarios at which each method is most efficient are complementary. This paper proposes a two-stage hybrid approach to combine CSB and CSFD. The new method usually has the same error control as CSB and CSFD. The efficiency, on the other hand, is usually much better than either component method.
Numerical and empirical approach in predicting the penetration of a concrete target by an ogive-nosed projectile
Authors: C. Y. Tham
Venue: Finite Elements in Analysis and Design (2006)

This paper demonstrates the application of both numerical simulation and empirical equation in predicting the penetration of a concrete target by an ogive-nosed projectile. The results from the experiment performed by Gran and Frew [In-target radial stress measurements from penetration experiments into concrete by ogive-nose steel projectiles, Int. J. Impact Eng. 19 (8) (1997) 715-726] are used as a benchmark for comparison. In the numerical simulations a 3.0-caliber radius-head steel ogival-nose projectile with a mass of 2.3 kg is fired against cylindrical concrete target with a striking velocity of 315m/s. The simulation, performed using AUTODYN 2-D, assesses three numerical schemes. namely Langrange, Euler-Lagrange coupling and smooth particles hydrodynamics SPH-Lagrange coupling, in predicting the maximum depth of penetration and the radial stress-time response of the concrete target. When assessing the three solution techniques we hypothesize that the effect of strain rate on strength for the concrete target does not adversely affect the prediction on the maximum depth of penetration and the radial stress-time response of the concrete target. In the empirical approach the penetration equation developed by Forrestal et al. [An empirical equation for penetration depth of ogive-nose projectiles into concrete targets, Int. J. Impact Eng. 15 (4) (1994) 395-405] is used to determine the maximum depth of penetration and the deceleration-time response. The deceleration-time response for the projectile using the empirical approach is compared with those obtained from the numerical simulations. Results from both the numerical and empirical approaches are consistent. The calculated depth of penetration from both approaches yield relatively good agreement with that obtained from the experiment The numerical simulations using each of the three numerical schemes are also able to reproduce the profiles from the radial stress measurements Simulations using the SPH numerical scheme give the best overall agreement. The good overall agreement with the experimental radial stress measurements and consistent results between both empirical and numerical approach, enhanced the confidence in engineers and ballisticians when using these two approaches in complementing full-scale testing.
Nonlinear regression modeling via regularized wavelets and smoothing parameter selection
Authors: Toru Fujii, Sadanori Konishi
Venue: Journal of Multivariate Analysis (2006)

We introduce regularized wavelet-based methods for nonlinear regression modeling when design points are not equally spaced. A crucial issue in the model building process is a choice of tuning parameters that control the smoothness of a fitted curve. We derive model selection criteria from an information-theoretic and also Bayesian approaches. Monte Carlo simulations are conducted to examine the performance of the proposed wavelet-based modeling technique.
Cross-border logistics with fleet management: a goal programming approach
Authors: Stephen C. H. Leung, Yue Wu, K. K. Lai
Venue: Computers and Industrial Engineering (2006)

In this paper, we introduce the cross-border logistics problem with fleet management. A major phenomenon of implementation of open-door policy in China is the move of Hong Kong-based manufacturers' production lines to China, crossing the border to take advantages of lower production costs, lower wages and lower rental costs. The finished products are then transshipped to Hong Kong, an efficient logistics hub well-equipped with reliable transportation facility, for exporting. We present a preemptive goal programming model for multi-objective cross-border logistics problem, in which three objectives are optimized hierarchically. We also describe a framework for incorporating decision-makers' opinions for determination of goal priorities and target values. A set of Hong Kong data have been used to test the effectiveness and efficiency of the proposed model. Results demonstrate the decision-makers can find the flexibility and robustness of the proposed model by adjusting the goal priorities with respect to the importance of each objective.
Sensitivity analysis of construction simulation using Cell-DEVS and microcyclone
Authors: Hong Pang, Cheng Zhang, Amin Hammad
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Simulation has been widely used in the construction industry to optimize productivity and resource allocation. However, simulation research that provides an explicit method to investigate possible space conflicts is still limited. This paper suggests a cell-based modeling approach to represent space resources in construction simulation, which enables spatial conflict analysis and visualization of the worksite and of the occupation of spaces. Comparison between the cell-based modeling approach and MicroCYCLONE approach is done to investigate the validity of the new proposed approach. Sensitivity analysis is applied to both methods to find the optimal resource combination.
