This paper presents a high-performance four-channel signal acquisition system composed of frequency channelizers and signal detectors in a single 6U VME slot. The intense computational complexity necessary to implement such an application requires field programmable gate arrays (FPGAs) to achieve a 10x performance density increase over a traditional GPP implementation. The same application perf...

inventory management in production-remanufacturing system has been receiving a great deal of attention in recent years. in literature review, production environment is composed of two sections. the first section is included: production process, remanufacturing process and other options considered in reverse logistics. the second section is included: collection and sorting processes. determinati...

Steady State Visually Evoked Potentials have been known for several decades and they appear in the primary visual cortex of brain as a result of light stimulation of the sense of sight. In this article a simple method for electroencephalographic data acquisition is presented. The system is based on the DSM-51 unit connected to goggles with blinking diodes and Mindset-1000 EEG amplifier with 16 ...

The fidelity of full vector seismic data acquired with systems of three-component (3C) receivers that are rigidly attached to an acquisition device is evaluated. The acquisition device is designed for rapid and cost-effective imaging of the upper 30m of the earth's surface. Multi-mode analysis of full vector seismic data has the potential to provide engineers and geophysicists with near-surface...

Habitat disturbance affects numerous ecosystem components and processes, but its effect on continuous soybean system is less available. Soybean was seeded following six preceding crops, including grain soybean (Glycine max L. Merill.), wheat (Triticum aestivum L.), sugar beet (Beta vulgaris L.), tobacco (Nicotiana tabacum L.), corn (Zea mays L.) and hemp (Cannabis Satia L.), on a Mollisol ...

Acquisition of image data for lightfield usually requires an expensive, complex and bulky setup. In this paper, we describe a simple method of acquiring the image data set. The method requires a normal handheld video camera, which is taken around the object to be rendered. We employ homography from the viewing/camera plane to the lightfield plane for obtaining the ray intersections with the lig...

Thomas, Christopher. PhD, Department of Computer Science and Engineering, Wright State University, 2012. Knowledge Acquisition in a System. I present a method for growing the amount of knowledge available on the Web using a hermeneutic method that involves background knowledge, Information Extraction techniques and validation through discourse and use of the extracted information. I present the...

In this paper we look at a number of approaches for modeling the system acquisition process. Beginning with the waterfall model of Winston Royce, we continue with derivation that includes more intricate and detailed waterfall models with feedback, including the “V” and spiral models. In addition we look at several acquisition strategies. In reviewing the various models we discuss our view that ...
