This paper studied the calibration method for a type of embedded smart sensors which are integrated with inertial, magnetic and vision sensors. A set of calibration and modeling methods which are suitable for the low cost applications have been proposed. For the deterministic items and nondeterministic items, we used the method of modulus matching of the input vectors and the method of time series analysis to calibrate and modeling them respectively;for the relative rotation between the accelerometers' frame and the camera frame, we proposed a calibrating method which is based on the gravity vector and plumb line. The experimental and simulation results demonstrated the practicability and effectiveness of these methods.

This paper examines fractional-order dynamical model of happiness. The dynamics of this system is studied numerically. The system displays many different dynamic behaviors, such as periodic motions, chaotic motions and divergence. It was found that chaos exists in the fractional-order system with order less than 3. In this study, the lowest order for this system to yield chaos is 2.97. The results are validated by the existence of a positive Lyapunov exponent. Moreover, chaos control and synchronization are also discussed here, which is a step into the research field of psychology on emotion control and synchronization by using fractional order models. © 2009 IEEE.

To improve the agility, dynamics, composability, reusability, and development efficiency restricted by monolithic federation object model （FOM）, a modular FOM is proposed by high level architecture （HLA） evolved product development group. This paper reviews the state-of-the-art of HLA evolved modular FOM. In particular, related concepts, the overall impact on HLA standards, extension principles, and merging processes are discussed. Also permitted and restricted combinations, and merging rules are provided, and the influence on HLA interface specification is given. The comparison between modular FOM and base object model （BOM） is performed to illustrate the importance of their combination. The applications of modular FOM are summarized. Finally, the significance to facilitate compoable simulation both in academia and practice is presented and future directions are pointed out.

The AAAI-10 workshop program was held on July 11-12, 2010, at the Westin Peachtree Plaza in Atlanta, Georgia. The workshop program included 13 workshops covering a wide range of topics in artificial intelligence. There were several presentations on particular formalisms for combining the levels of planning from the perspectives of classical planning, motion planning, POMDPs, search-based planning, and temporal logic-based constraints. Henry Lieberman from Massachusetts Institute of Technology Media lab.ratory presented work developing a platform for knowledge acquisition and usage from expert users, built upon experience with eliciting information from nonexperts in a collab.rative manner. The objective of the AAAI Workshop on Goal-Directed Autonomy (GDA) was to encourage discussion and novel contributions on intelligent agents that can self-select their goals. Jeremy Baxter from QinetiQ focused on user interaction, while Nick Hawes described a goal-directed reasoning framework for controlling a mobile robot.

As a fundamental problem of wireless sensor networks, the minimal exposure path problem corresponding to the sensor network's worst-case coverage plays an important role in the applications for detecting intrusions. However, most existing works about minimal exposure path are based on omnidirectional sensors. In contrast, this paper studies the minimal exposure path problem for directional sensor networks. We first develop a directional sensing model: directional sensitivity model. Then, we formulate the minimal exposure path problem by using two sensing intensity functions: all-sensor intensity function and maximum-sensor intensity function, and generate two weighted grids to convert the minimal exposure path problem into two discrete geometric problems. Based on the above weighted grids, we also develop two approximation algorithms to find the minimal exposure path for the directional sensitive model. We conduct extensive simulations to validate and evaluate our proposed models and algorithms.

In wireless sensor networks, most existing works on region coverage mainly concentrate on the omnidirectional sensor based full coverage, which ensures that all points in the sensor-deployed region are covered. In contrast, this paper studies the problem of exposure-path prevention for the region coverage in directional sensor networks. Because the exposure paths are prevented as long as no moving objects or phenomena can go through a sensor-deployed region without being detected, exposure-path prevention does not require full coverage, and instead it only needs the partial coverage. Towards this end, we apply the percolation theory to solve the exposure path problem for directional sensor networks. In particular, we map the exposure path problem into a sector based percolation model, and then derive the bounds of critical density where directional sensors are deployed according to a 2-dimensional Poisson process. Also conducted is a set of extensive simulations to validate and evaluate our developed models and schemes. ©2009 IEEE.

Many biological sequence databases have redundant sequences which are not helpful to statistical analysis and require more computational time and resources to process. This lead us to design a new and fast program to generate a non-redundant sequence set. A graph theoretic algorithm was designed to process BLAST output and remove redundant proteins from a protein sequence database. We have developed a program named BlastCuller which can be used to generate a non-redundant protein database. BlastCuller is a flexible program with a parameter of sequence similarity cutoff, which can be a decimal from 0.0 to 1.0. This program can be downloaded from http://***/BlastCuller. html. ©2009 IEEE.

systems development needs to reconcile views from many roles, such as domain experts and engineers. A particular challenge is the multitude of models for requirements and quality, which can get time consuming and error prone to trace, change, and verify. In this paper we introduce an ontology-supported component-based systems engineering approach for the production automation domain that describes explicitly stakeholder quality requirements and traces design decisions to generate new system and software versions that implement these requirements. The ontology approach is expected to allow continuous modeling and extracting model views for all roles involved to a) improve the quality assurance of system requirements;b) support more explicit feedback on the quality of intermediate models during systems development;and c) provide better auditing capabilities of the systems development process. Based on an industry case study, we describe the ontology concept of the system, the development process, and how software quality can be measured and improved. Copyright 2008 ACM.
