Improved Particle Swarm Optimization Algorithm Based on Periodic Evolution Strategy

This paper proposed a novel improved PSO algorithm based on an periodic evolution strategy (PSO-PES). From experiments, we observe that the novel search strategy enables the improved PSO to make use of swarm’s information on velocity more effectively to generate better quality solutions iteratively when compared to exiting PSO variants. And PSO-PES significantly improves the PSO’s performance and gives the better performance than original PSO. Another attractive property of the improved PSO is that it does not introduce any complex operations to the original simple PSO framework. The only difference from the standard PSO is the best solution will update by a periodic evolution strategy. PSO-PES is also simple and easy to implement like the original PSO.

Optimization Strategy for AODV Routing Protocol Based on Modified Ant Colony Algorithm

The Ad hoc On-Demand Distance Vector (AODV) routing protocol doesn’t consider the node itself condition in the route discovery. So it may cause some local nodes congestion, thus affects the whole transmission characteristic of the net; Meanwhile, in high-speed mobile network conditions, due to the dynamic change of topology structure, causes the communication link expire frequently, therefore increased the transmission latency greatly. This paper combines with ant colony algorithm, based on AODV routing protocol, proposed a modified routing protocol. The modified routing protocol considers the node routing load, remaining power, routing hop count, and so on. In the route discovery stage, the downward node in communication link makes the judgment to its own situation, avoids the node blindly processing route request; with the improved ant algorithm, the modified routing protocol makes the source node establish many ways to the destination node. Finally, the NS2 simulation shows that the modified protocol reduces the average delay, routing load and packet loss rate while increasing the data forwarding capacity of nodes.

Learning Frequent Episodes Based Hierarchical Hidden Markov Models in Sequence Data

We present a non-overlapping serial Episodes Based Hierarchical Hidden Markov Model (EBHHMM). Each EBHHMM is associated with two types of temporal frequent patterns, i.e. non-overlapping serial episodes and the presented SEI (Serial Episode Interactions). Serial episode interaction is a set of non-overlapping serial episodes which are correlated and occurs frequently in sequence. As the key advantage of our approach, we do not need any prior-knowledge to learn the structure of EBHHMM. Extensive experiments perform on real world data demonstrate that EBHHMM gets larger maximum log likelihood (has better quality) than existing models.

A Context-Aware Semantic-Based Access Control Model for Mobile Web Services

The emergence of ubiquitous mobile devices, such as mobile phones, PDAs, and laptops, has sparked the growth of mobile web services. Unlike traditional identity/role based approaches for access control, access decisions for mobile web services will depend on the combination of the required attributes of user and the contextual information. As well as, it is crucial that the policy system can understand and interpret semantics of the context. This paper proposes a context-aware semantic-based access control model (called CASBAC) to be applied in mobile web services environment by combining semantic web technologies with context-aware policy mechanism. The proposed model adopts a context-centric policy method, and grants permissions to users according to current context information and allows high-level description and reasoning about contexts and policies. The model-theoretic semantics of CASBAC is an extension of the model-theoretic semantics defined in the OWL standard and SWRL.

Optimization of the Expected Utility Portfolio Selection Model with Box Constraints

A new expected utility (EU) portfolio selection model is proposed under the assumption that the trading volume has the box constraints. In the model, the expected utility function is quadratic. The model is solved by a pivoting algorithm which needn’t be added any slack, surplus and artificial variable, and is easy to operate and works efficiently. A numerical example of a portfolio selection problem is given to compare the new model and the EU portfolio selection model not considering upper bounds. The comparison shows that when the risk preference coefficient is greater than a critical value, the risk and expected return don’t increase as the coefficient increases; The relationship between the risk preference coefficient and the expected return (or risk) is nonlinear while that is linear in the case when short sales are allowed; the efficient portfolio selection considering the box constraints is subset of that not considering the constraints.

The Tightest Geometry for Lowest GDOP in Range-Based 2-D Wireless Location Systems

In wireless location systems the geometry between target and measuring points influences the positioning accuracy of the target. It is usually quantified by the geometric dilution of precision (GDOP). The GDOP depends on the geometry between target and measuring points. In this paper, firstly, a close form for the GDOP is derived as a function of both the number of measuring points and their bearing angle relative to the target. Then, such geometries that produce the lowest GDOP are reviewed with the close form expression of GDOP. Finally, a new geometry is proposed for absolute-range based 2-dimension (2-D) wireless location systems. The proposed geometry not only has the lowest GDOP but also forms the narrowest sector. In the proposed geometry all measuring points are distributed within a sector of

Saliency-Based Automatic Target Detection in Remote Sensing Images

Automatic target detection in satellite images remains a challenging problem. Previous methods mainly focus on independent detection of multiple targets. In this paper, we propose a simultaneous multi-class target detection approach by using saliency computation. The advantages are twofold. First, saliency map is computed only once for all target types. This saves a large amount of computational time but does not miss any targets. Second, we use small regions, obtained from over-segmentation, to be the elementary unit of detection. This provides shape information to remove most false candidates for the final detection. Experiments show that the targets can be quickly detected and the detection rate is as high as the independent detecting methods.

Improved Sparsing of Extended Information Filter for Vision-SLAM

There are a number of algorithms used on Simultaneous Localization and Mapping(SLAM). The sparse extended information filter (SEIF) algorithm is deduced by the sparsification treatment to EIF algorithm, which is the information form of EKF. SEIF has been successfully implemented with a variety of challenging real-world data sets and has lead to new insights into scalable SLAM. However, the computational burden related to information matrix balloons with respect to the increase of the mapped landmarks, the most computational cost is in recovery information matrix (inverse matrix).In this paper, by analyzing the every steps of information matrix update in SEIF process, A sparsification rule is put forward, which enforce the elements into zero according to setting a threshold and computer inverse information matrix with the method of tri-diagonal matrix splitting according to observation information of sparsification time. the computational complexity is much lower by using new sparsification rule. The algorithm used in vision-SLAM shows that the computational complexity of the SEIF algorithm is a constant, which is independent of environment features. That means SEIF has a high value of application in large-scale environment with a large number of features.

This study aims to using visible and near infrared spectroscopy (VIS-NIRS) for

in situ

determination of tomato maturity. A new index (GS) defined as the ratio of current growing age (days) to on-vine duration before harvest (days) was proposed. A partial least squares regression (PLSR) with leave-one-out cross validation was used to build calibration models for each cultivar spectra and the combined spectra of all cultivars. Result shows that PLSR for GS is successful and robust in predicting tomato maturity with coefficient of determination (



) of 0.89-0.92, and residual prediction deviation (RPD) of 3.00-3.70 for the single cultivar model and the general one. The analysis of PLSR coefficient plot indicates the consistency of assigning important wavelength bands for tomato cultivars. It is concluded that the proposed GS index can be adopted with common-purpose for maturity determination of on-vine tomatoes, which allows for selective harvest of tomatoes by a picking robot.

A Unified Operational Semantics for UML in Situation Calculus

An arising interest in the study of UML formal semantics is to integrate UML Diagrams into a uniform semantic model. In this paper, we propose a unified operational semantics for UML based on the Situation Calculus (SC) which is a sophisticated action theory and capable of modeling general dynamic systems. Specifically, UML models are treated as tailored dynamic systems in SC, with vocabularies borrowed from the UML metamodel. Structural diagrams, Class Diagrams and Object Diagrams, are modeled by Eternals for consistency checking. Behavioral diagram, the State Machine Diagram is modeled by Fluents and corresponding Axioms in SC. To analyze and test these dynamic diagrams, we appeal to Golog, an executable high-level programming language based on the SC. By executing Golog programs, UML diagrams can be analyzed and tested under a single semantic model.
