In this literature, a data pre-processing circuit designs and analyses for an infrared image seeker of a subsonic cruise missile are proposed. The flight speed of the missile is 250m/s. Therefore, automatic contrast control and automatic brightness control are usually needed to keep wanted contrast and brightness for best image properties in target recognition and tracking; especially for the m...

An infrared (IR) measurement technique is presented that has been developed to measure electromagnetic (EM) fields. This technique uses a minimally perturbing, thin, planar IR detection screen to produce a thermal image (e.g., an IR thermogram) of the intensity of the EM energy over the two-dimensional region of the screen. Several examples are presented using this thermal technique to measured...

The evaluation of the psychophysiological state of the interlocutor is an important element of interpersonal relationships and communication. Thermal infrared (IR) imaging has proved to be a reliable tool for non-invasive and contact-less evaluation of vital signs, psychophysiological responses, and emotional states. This technique is quickly spreading in many fields, from psychometrics to soci...

In this work we study the problem of finding axesparallel regions of maximum density for weighted point sets in IR and IR. The 2-d variant is motivated by applications in thermal analysis of VLSI chips.

In 2010 approximately 68,720 melanomas will be diagnosed in the US alone, with around 8,650 resulting in death. To date, the only effective treatment for melanoma remains surgical excision, therefore, the key to extended survival is early detection. Considering the large numbers of patients diagnosed every year and the limitations in accessing specialized care quickly, the development of object...

Abstract Using holographic methods in the Einstein-Maxwell-dilaton-axion (EMDA) theory, it was conjectured that the thermal diffusion in a strongly coupled metal without quasi-particles saturates an universal lower bound that is associated with the chaotic property of the system at infrared (IR) fixed points [1]. In this paper, we investigate the thermal transport and quantum chaos in the EMDA ...

farming organic vegetable and crops have grown as a market desiring commodity. weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. a few chemicals are commonly applied in organic farming. thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

A detailed description of the CLEARFAST system for thermal IR stand-off minefield survey is given. The system allows (i) a stand-off diurnal observation of hazardous area, (ii) detecting anomalies, i.e. locating and searching for targets which are thermally and spectrally distinct from their surroundings, (iii) estimating the physical parameters, i.e. depth and thermal diffusivity, of the detec...

In this research sodium bicarbonate (NaHCO3) was introduced to generate carbon dioxide gas (CO2) to the existing nitrogen gas (N2) of elastomeric foam, to lower thermal conductivity (K). Various loadings of NaHCO3 (0 to 60 phr) were added into the azodicarbonamide (AZC)-containing compound and its properties were then determined. Two vulcanization methods, i.e., hot air and infrared (IR), were ...

Infrared (IR) technology has traditionally been applied to military use and remote sensing. During the last two decades, the cost of IR cameras (especially uncooled imagers) has been significantly reduced with the development of CCD technology, and therefore civil applications have increased constantly due to its unique features. One of such applications is IR face recognition (Prokoski et al.,...
