Many real world problems have iterative behaviors, so planners should be able to tackle such problems
and generate iterative plans. Iterative actions have been considered by a few of planners, and most of the
efforts have been based on linear planning. In this paper, we show how SAT-Plan, which is one of the
fastest existing planners, can be extended to generate recursive plans. Generated recursive plans are
similar to those that are generated by humans for iterative problems. The main idea in this work is based
on the mathematical induction, and has been implemented. Results obtained from testing the extended
SAT-Plan on several examples from the blocks-world domain, confirms the success of the proposed idea. عدم مشاهده کامل

Conventional software validation methods for real-time and reactive programs are not fully reliable. Considering
complexity of formal verification and incompleteness of testing approaches, runtime verification approach is used. In
this paper, Safety properties (after extracting from program requirement specification) are represented in Real-Time
Logic (RTL) and fault tolerant module reaction are added to the program.
Program monitoring module (which is realized by Functional, Timing and Deadline Aspects) is weaved to the
program code. The enriched program executes in the environment. The monitoring module verifies program behavior
by considering the specified safety properties and when any violence of a property is detected, then the specified
reaction (Fault Tolerance) activates and navigates the program to a safe state. عدم مشاهده کامل

Variability management is a major concern in successful exploitation of variabilities and
commonalities of software product families which also affects different aspects of development
activities. To use software product line approach in information systems context, it is necessary to
bring in variability in different phases of the life cycle, including business modeling which is
recognized as a key part of developing enterprise information systems.
This paper presents a method for variability management at business process level which covers
the activities of eliciting variability, representing variability in business process models, and also
managing dependencies among different variabilities. The method supports traceability by mapping
variabilities at business process level to assets of lower levels of abstraction, including feature and use
case models. To model business processes, UML activity diagrams are exploited. عدم مشاهده کامل

Real-time video transmission is considered as an important way for information broadcasting. One noticeable
example in this area is E-leaning applications, which is based on real-time video processing and transmission. On
the other hand, the process of registration is a fundamental component in automatic image and video processing.
In our previous work, we implemented a new method for cut detection technique based on dominant lines and
angles. This paper introduces a new video registration technique that uses dominant angles extracted from edge
information of the video frames in one shot. To the best of our knowledge, it is the first works done for
registration in E-learning applications. This method is compatible with our application’s requirements and has a
low complexity and high speed. We compare our method against three established techniques and present our
results using different video sequences. عدم مشاهده کامل

This paper presents a computationally effective trajectory generation algorithm for omni-directional mobile
robots. In this algorithm we use the Voronoi diagram to find a sketchy path that keeps away from obstacles and
then we smooth this path with a novel use of Bezier curves. This algorithm defines velocity magnitude of a robot
along the curved path to satisfy optimality conditions and dynamic constrains. The algorithm has been
implemented on real robots, and we present experimental results in different environments. عدم مشاهده کامل

The security of networked computers plays a strategic role in modern computer systems. This task is so
complicated because the determination of normal and abnormal behaviors in computer networks is hard, as the
boundaries cannot be well defined. This paper proposes a parallel genetic local search algorithm (PAGELS) to
generate fuzzy rules capable of detecting intrusive behaviors in computer networks. The system uses the
Michigan’s approach, where each individual represents a fuzzy rule which has the form “if condition then
prediction”. In the presented algorithm the global population is divided into some subpopulations, each assigned
to a distinct processor. Each subpopulation consists of the same class fuzzy rules. These rules evolve
independently in the proposed parallel manner. Experimental results show that the presented algorithm
produces fuzzy rules which can be used to construct a reliable intrusion detection system. عدم مشاهده کامل

Error Back Propagation, a class of neural networks, is proposed to solve the inverse kinematics problem in
robotic manipulator. In this approach a network has been trained to learn a desired set of joint angles positions
from a given set of end effectors positions. This paper demonstrates some methods of Back Propagation neural
network which can be used to solve inverse kinematics. Next the performance of these methods has been
compared for inverse kinematics problems.
The used Error Back Propagation techniques are the Standard, Momentum and Delta Bar- Delta. عدم مشاهده کامل

The flexible DFT strategy helps designers control the eventual cost of test during the chip design phase. To
reach a uniform test strategy for CPU data path, we use S-graph information. But register files and internal
memory structures cannot be easily represented by S-graphs. In most processors investigated, one can find some
sort of internal memory like general-purpose registers, stacks or queues. The control hardware and addressing
schemes of such structures make it difficult to test them. We design a wrapper around these structures to isolate
them from data path and incorporate them to S-graphs applications. These compatible S-graphs provide a
uniform BIST strategy for the whole data path. The wrapper design can test itself concurrently with other
modules so it can reduce the test application time. We apply our method on SAYEH CPU as a vehicle. عدم مشاهده کامل

This paper is about the vision and odometry errors of a sweeper mobile robot. The robot takes advantage of
color recognition in its vision in order to detect different types of objects having different colors. An effective
artificial neural network which is extremely easy to implement and is surprisingly quick in practice for mobile
robots is introduced. Consequently, the connectionist is applied on the robot for object detection and the gained
results are compared with other methods. Also experimental tests plus statistical analyses are carried out in
order to measure the robot localization errors. عدم مشاهده کامل

Several methodologies with their own characteristics have been proposed in the area of agent-oriented software
engineering. Consequently, deciding which methodology to select in a specific case is an important issue and it can
lead to decrease software development cost and effort. Thus, importance of evaluation of methodologies will be
highlighted in choosing the appropriate methodology in the development process of an application. It can also help in
developing new methodologies and improving existing ones. In this paper, we are going to provide an evaluation
framework of agent oriented methodologies. To demonstrate the usage of the suggested framework, it is applied to
evaluate two methodologies (MESSAGE and Prometheus) using a proper example. Results show that, using our
method, methodologies can be truly compared and evaluated. عدم مشاهده کامل
