This paper presents the implementation of a JPEG encoder that exploits minimal usage of FPGA resources. The encoder compresses an image as a stream of 8times8 blocks with each element of the block applied and processed individually. The zigzag unit typically found in implementations of JPEG encoders is eliminated. The division operation of the quantization(More)
The efficient layout planning of a construction site is a fundamental task to any project undertaking. In an attempt to enhance the general practice of layout planning of construction sites, the paper introduces a novel approach for producing the sought layouts. This approach integrates the highly sophisticated graphical capabilities of computer-aided(More)
This paper presents a hybrid framework that integrates value analysis and decision making for eliciting and evaluating design alternatives. Value analysis approach relies on the integration of the functional analysis through the systematic use of the functional analysis system technique and quality function deployment. This value analysis methodology(More)
This paper proposes new fuzzy-based scheme providing position information vital for smart home applications. The scheme runs efficiently on the economical wireless ZigBee nodes and uses the link quality indicator (LQI) measured without the need for any additional hardware. It uses fuzzy logic to represent measure noise and surrounding environmental impacts.(More)

This paper proposes a novel algorithm for constructing multiclass SVM-based binary decision tree classifiers. The basic strategy of the proposed algorithm is to set the target values for the training patterns such that linear separability is always achieved and thus a linear SVM can be constructed at each non-leaf node. It is argued that replacing complex,(More)
Wind turbine construction is a challenging undertaking due to the need to lift heavy loads to high locations in conditions of high and variable wind speeds. These conditions create great risks to contractors during the turbine assembly process. This paper presents a simulation-based system to aid in the construction planning of wind turbines. The system is(More)
Modelling in the architecture, engineering, and construction (AEC) industry is a fundamental step for product and project delivery, and serves multiple purposes from visualization, communication, simulation, analysis, decision making, to performance assessment. For long, the AEC industry has used different types of modelling schemes. Typical examples(More)
Wind energy as a power source is attractive alternative to fossil fuels. Wind farms are typically constructed in undeveloped rural areas with challenging topography. The lack of a paved road network leading to the site and within the site itself pose significant challenges to the planning of wind farm construction. Therefore the selection of the most(More)
