Interpolations are among the most important tools for image processing. However, whether they are used for image compression and reconstruction purposes or for the increase of the image resolution along vertical, horizontal or both dimensions, the induced interpolation errors are often only qualitatively and a posteriori described. In this paper, we propose to extend a method used in an OFDM co...

Driven by major advances in sensor technology, GPS-enabled mobile devices and wireless communications, a large amount of trajectory data is currently generated and managed in scores of application domains. This inspires a tremendous amount of research effort analyzing large scale trajectory data from a variety of perspectives in the last decade. However, people are still witnessing that data qu...

The food processing industry has matured over the years with an impressive record on safety and a vibrant marketplace for new product evelopment. Consumer demands for high-quality products has inspired researchers and the food industry to explore alternative methods as eplacement for traditional processing methods. The food industry is poised to adopt cost effective technologies that offer bett...

ABSTRACT Background: The radiographic image accuracy depends on the X-ray film information visibility. Good visibility is found by good contrast. Radiation exposure parameters (kVp, mAs) and film processing conditions have impact on contrast. In dentistry radiography machines, exposure time and processing procedure are set by radiographer. No optimized exposure time and process...

Most watermark methods use pixel values or coefficients as the judgment condition to embed or extract a watermark image. The variation of these values may lead to the inaccurate condition such that an incorrect judgment has been laid out. To avoid this problem, we design a stable judgment mechanism, in which the outcome will not be seriously influenced by the variation. The principle of judgmen...

The contemporary large scale measuring systems in the real-time environment make extensive use of histogramming as a tool for the experimental data quality monitoring. The processing of a large number of data channels requires a suitable computing power where the graphical processors seem to be well suited. Histogramming operations run on the central and graphics processing units are discussed....

This paper presents an architecture for addressing the transformation of large volume of data generated by pervasive and other sensor applications in a timely manner (or subject to quality of service or QoS constraints). As the size and rate at which raw data is generated increases, novel approaches for meaningful reduction and extraction of actionable information from the data are needed. In t...

In developing countries, it is common to site (or locate) industries without environmental impact assessment. In this study the impacts of two food processing industries on land use and land capability, noise and vibration, environmentally sensitive areas and visual quality as environmental elements were investigated. The research method adopted was the investigative survey research approach (I...

Pistachio is one of the most important agricultural crops of Iran. It is a nut from Anacardiacea family and its domesticated species is called Pistacia vera L. Regarding to pistachio importance and usage and by the expanding of pistachio cultivate, it is necessary to improve agricultural situation and by establishing well equipped processing and packaging units near the farms, it is possible to...
