The novelty of the paper is the comparison between the inverse dynamic solution based on Lagrangian formulation and the direct dynamic solution of the Stewart platform by simulation with ADAMS commercial engineering package. In this paper, based on the inverse kinematics, the Jacobian matrix and the dynamic equations of the six-degree-of-freedom Stewart platform are derived. The Inertia matrix and...
Decision making is an important task for enterprise managers, and is typically based on various data sources derived from information systems, such as enterprise resource planning, supply chain management and customer relationship management. Numerous business intelligence tools (BI) thus have been developed to support decision making. Some existing BI tools have several limitations, for example lacking...
The discrete wavelet transform has taken its place at the forefront of research for the development of signal and image processing applications. Hence this paper is proposed on the work of design of hardware for the computation of Floating Point Discrete Wavelet Transform using Harr wavelet. The proposed hardware was implemented using VHDL and components were designed at the gate level. This resulted...
Book reviews are comments written by readers regarding their experiences about a particular book. Some reviews contain useful information and may help prospective buyers in making a purchase decision, while some are viewed as less helpful, such as, complaints about shipping delay. The review's content is the key to differentiating them. Presenting a methodology for evaluating the helpfulness of a...
One of the disputable issues in the new generation of multimedia networks that requires to be concentrated is decreasing the signal delay and bit error rate and increasing the network efficiency and quality. This study evaluates the results of uplink 10 Gbps base-band radio over 30 km coarse wavelength division multiplexing single mode fiber in three important factors for multimedia communication...
Safety topic as the same as many topics in transportation system, impresses many factors and is influenced by the other factors. In Iran the most attention was concentrated in executive engineering activities and it was conceived that with only physical adjustments, accident rate will be reduced. In recently years identification and remedying of Accident prone zones was considered by experts, but...
In this paper, we investigate predicting the Stock Exchange of Thailand Index movement. Currently, there are two stock markets in Thailand; the Stock Exchange of Thailand (SET) and the Market for Alternative Investment (MAI). This paper focuses on the movement of the Stock Exchange of Thailand Index (SET Index). The back propagation neural network (BPNN) technology was employed in forecasting the...
The peak volume characteristics are of great significance to transportation planning, design, and management. However, the amount of researches conducted on the subject of site-to-site variability of the peak volume characteristics is relatively limited, which largely restrict the identification of appropriate peak volume factor and other pertinent parameters in traffic analysis. This paper discussed...
Clustering in wireless sensor networks is one of the crucial methods for increasing of network lifetime. There are many algorithms for clustering. One of the cluster based algorithm in wireless sensor networks is LEACH algorithm. In this paper we proposed a new clustering method for increasing of network lifetime. In proposed method Clustering is done symmetrically and the best node with respect to...
Based on linear combination with differential Gaussian pulse, a designing impulse radio waveforms method for Ultra Wideband (UWB) wireless communications was investigated. According to the spread spectrum effect of the shaping factor and differential coefficient, a simple pulse design method on constructing differential Gaussian pulse was proposed that made use of a linear only triple-pulse combination...
For any file, the modification, access and creation date and time stamp (MAC DTS) is a major parameter, which if preserved properly can be used to gain crucial evidence about activities on the file. Activities on a file system is generally protected by access control mechanism specific to the operating system; discretionary or mandatory access control mechanism being the most common ones. Generally,...
The objective of this work is to propose a membrane computing model for software requirement engineering activities during the inception phase of the software development. The bio-inspired approach is used in requirement engineering for the transformation of user requirements into system requirements using a probabilistic distributed computing model with abstraction coefficients, amalgamation factors...
In this paper, we propose a multi objective stochastic model with linear partial information on probability distribution (MSPLI) for portfolio selection problem. We apply an extended chance constrained compromise programming approach to obtain the deterministic equivalent of the MSPLI model.
The measurement of parameters for obtaining the mathematical model of the Level process station has to make accurately so as to obtain satisfactory performance of the system. The subject of this paper is concerned with the precise level control of a Level process station. The mathematical modeling of the system is done and control law for fuzzy and fuzzy immune PID is established. The Simulink of...
This study deals with the joint multi-item replenishment problem under trade credit. All existing studies about trade credit focused on single-item replenishment policy. However, joint multi-item replenishment has been widely applied in many industries to take advantage of transport economies of scale. In this paper we extend the traditional inventory model by considering trade credit and multi-item...
Today many organizations used data warehouse for strategic decision making. Today's real-time business stresses the potential to process increasingly volumes of data at very high speed in order to stay competitive in market. Data Warehouse is populated by data extraction, transformation and loading from different data sources by software utilities called ETL (Extraction, transformation & loading)...
Breast carcinoma is considered as the second major cause of death in females. Malignant tumor affects some tissues of breast and may spread over neighboring tissues. Early detection of this malignant mass is very important to save the precious lives. Although the death rate is reduced by application of modern tools yet research for optimal solutions is still in progress to bring more comprehensive...
A circular profile micro strip antenna and its related structural dimensions meant for 5850-7075 MHz Malaysia HAPS operating band are investigated here. Appearing by three layers and having layer three surface copper re-shaped on a microwave laminate. It was by varying the middle air gap spacing's height covering layer two regions. At the same time, this conditions will permit copper at layer three...
