TL;DR: A novel approach to measure traffic parameters is described, based on applying edge-detection techniques to the key regions or windows, which eliminates the need of a background frame, which is an essential, but unreliable technique for background-based image-detector methods.
Abstract: Traffic information is an important tool in the planning, maintenance, and control of any modern transport system. Of special interest to traffic engineers are parameters of traffic flow such as volume, speed, type of vehicle, queue parameters, traffic movements at junctions, etc. Various algorithms, mainly based on background differencing techniques, have been applied for this purpose. Since background-based algorithms are very sensitive to ambient lighting conditions, they have not yielded the expectative results. In this paper, we describe a novel approach to measure traffic parameters. This approach is based on applying edge-detection techniques to the key regions or windows. This method of measuring road traffic parameters eliminates the need of a background frame, which is an essential, but unreliable technique for background-based image-detection methods. A dynamic threshold selection technique has also been introduced to select the threshold value automatically. The image process algorithm has been applied to measure basic traffic parameters such a traffic volume, types of vehicles, as well as the complex traffic parameters such as queue parameters and movements of vehicles at a traffic junction.

TL;DR: In this paper, the ant colony optimization (ACO) algorithm is employed for optimal design of skeletal structures, where the advantage of using ACO lies in the fact that the discrete spaces can be optimized in a simple manner.
Abstract: In this article, the ant colony optimization (ACO) algorithm is employed for optimal design of skeletal structures. The advantage of using ACO lies in the fact that the discrete spaces can be optimized in a simple manner. The results of the present method are compared to those of the other optimization algorithms for some classic examples from the literature.

TL;DR: The unique physiochemical properties of metal nanoparticles suggest that they can perform as novel types of scaffolds for bone tissue engineering, and the basic principles of various nanoparticle‐based composites and scaffolds are discussed.
Abstract: Tissue is vital to the organization of multicellular organisms, because it creates the different organs and provides the main scaffold for body shape. The quest for effective methods to allow tissue regeneration and create scaffolds for new tissue growth has intensified in recent years. Tissue engineering has recently used some promising alternatives to existing conventional scaffold materials, many of which have been derived from nanotechnology. One important example of these is metal nanoparticles. The purpose of this review is to cover novel tissue engineering methods, paying special attention to those based on the use of metal-based nanoparticles. The unique physiochemical properties of metal nanoparticles, such as antibacterial effects, shape memory phenomenon, low cytotoxicity, stimulation of the proliferation process, good mechanical and tensile strength, acceptable biocompatibility, significant osteogenic potential, and ability to regulate cell growth pathways, suggest that they can perform as novel types of scaffolds for bone tissue engineering. The basic principles of various nanoparticle-based composites and scaffolds are discussed in this review. The merits and demerits of these particles are critically discussed, and their importance in bone tissue engineering is highlighted.
