There are basic differences between multimedia databases and traditional databases, which raise new issues such as fuzzy queries. In the recent years, fuzzy queries in multimedia database have been paid attention to greatly and developed the applications of this field remarkably. An application of multimedia database is to identify the person' image for which image process techniques are used. In this paper, we suggest a new method to identify the persons' face image in distributed database based on fuzzy queries with specific weighing. The results show that the suggested method vitas much more accuracy and less search time rather than the previous algorithms which used image processing algorithms. © 2011 IEEE.

Detonation chambers (either mobile or fixed) are used worldwide for a wide range of applications. At present, a 1/7 scale model of a 1 ton detonation chamber is available for extended testing in Belgium. The chamber is a single wall cylindrical vessel with semielliptical ends. Each time an explosive charge is fired in the vessel, that vessel is submitted to a number of deformation cycles. A series of strain gauges measures the deformation of the vessel walls. Experimental peak strains and vibration frequency can be compared with predicted values based on simple formulas. Measured values are reasonably close to the estimated values. The influence of the shape of the charge is studied. The shape has an important influence on the chamber response. For a fixed charge mass, a spherical charge causes less deformation than a cylindrical charge and is therefore advantageous from a fatigue point of view. © 2011 American Society of Mechanical Engineers.

Antisolvent synthesis of micron scale Griseofulvin was carried out with simultaneous suspension stabilization under low power ultrasonic agitation. The organic solvent plays an important role because the supersaturation could be varied by using different solvents and the physicochemical characteristics of the suspension are also altered, which affects stability. In this study we present the effect of solvents on particle formation, polymorphism and stability of micron scale Griseofulvin formation in aqueous media. © 2010 Elsevier B.V. All rights reserved.

A simplified method for incorporating gravitational effects into the analysis of structural vibrations, and for determining the relative importance of those effects, has been developed. The nonlinear effect has been simplified by incorporating only the firstorder gravitational effects into the structural stiffness formulation, and demonstrating through both analysis and experiment that the first-order stiffness additions are sufficient to accurately characterize the gravitational effects in most cases. The simplified formulation also provides a convenient method for determining the conditions under which the effects of gravity should be considered. Copyright © 2013 by ASME.

Vessels subjected to internal impulsive loadings, such as those used for controlled-detonation chambers, can be designed for a single impulsive load application or for multiple impulsive loads. Design of a single-use vessel may take advantage of the capability of the vessel material to absorb energy through elastic-plastic behavior, provided that the public health and safety is protected, even though the owner's investment in the vessel may be compromised because of severe distortion and potential loss of containment functionality. However, when the vessel is designed to contain multiple internal impulse loads, the usual design practice is to require completely elastic response or, at most, very localized elastic-plastic behavior. A recently approved ASME Boiler Pressure Vessel Code, Section VIII, Division 3 action (Code Case 2564-2) provides limits for the accumulated plastic strains in such vessels, including a limit on the accumulated plastic strain averaged across the wall thickness of the vessel, that are sufficiently conservative to permit the design of vessels for both single-impulse and for multiple-impulse applications. Analytical or experimental demonstration to meet the Code Case 2564-2 strain limits is straightforward for the single-impulse vessel design and is relatively straightforward for multiple-impulse vessel designs when the vessel response to any of the individual impulsive loads is nearly elastic. However, when the design-basis impulsive loading for a multiple-impulse vessel design leads to significant plastic straining, the demonstration of design adequacy becomes extremely complex, raising issues of impulsive loading sequences (since elastic-plastic response is load-path dependent, what is the temporal order of the impulse loadings?) and demonstration of shakedown to elastic or near-elastic behavior. In such cases, an analytical demonstration of design adequacy may be impractical, while an experimental demonstration may be both practical and illuminating, especially if the demonstration is carried out at a scale that is both economical and convincing. Here, a one-seventh-scale model of a controlled-detonation vessel is used as the basis for demonstrating the effect of shakedown to essentially elastic behavior, with no further accumulation of plastic straining, along with the satisfaction of ASME Code Section VIII, Division 3, local ductility exhaustion requirements. The experiments on a scale model vessel have proved that the phenomenon of shakedown can be demonstrated experimentally, for internal detonation loadings that initially led to plastic strains up to 0.7. © 2012 American Society of Mechanical Engineers.

The antisolvent synthesis of micrometer-scale particles, their stabilization in suspension, and their subsequent self-assembly as homogeneous polymer films suitable for drug delivery were studied. Ultrasonic agitation was used in the precipitation of the drug particulates, stabilization was carried out with hydroxypropyl methylcellulose (HPMC), and finally, drug-encapsulated films containing HPMC and polyvinylpyrrolidone were synthesized. These contained as much 28% of the drug Griseofulvin, and the particles were distributed uniformly throughout the films. Most importantly, the redispersion of the drug-loaded films in an aqueous matrix showed that the crystallinity remained unaltered, and there was no appreciable increase in the particle size distribution. © 2010 Wiley Periodicals, Inc.

Hydrostatic or pneumatic overpressure testing prior to actual service provides a number of purposes related to structural integrity of pressure vessels, including some degree of confirmation of both the design and fabrication processes. For detonation chambers designed to control impulsive pressure loadings, preservice hydrostatic testing at impulses greater than those expected during normal operation can provide an added benefit - the ability to reduce cyclic fatigue damage caused by long-term, high-throughput operation, where the chamber may be use to control hundreds or even thousands of detonations without compromising structural integrity through excessive fatigue crack initiation and growth. This paper illustrates the favorable characteristics of controlled detonation chamber operation following an initial preservice impulsive over-testing program that demonstrates shakedown and satisfaction of strain ratcheting criteria, leading to favorable cyclic fatigue behavior during subsequent long-term, high-throughput operation.

The anti-solvent synthesis of micron-scale particles, their stabilization, and subsequent self-assembly into polymer films suitable for drug delivery is presented. The colloidal particles were stabilized using low molecular weight hydroxypropyl methylcellulose (HPMC), while drug encapsulation was carried out with high molecular weight HPMC and polyvinylpyrrolidone (PVP). Griseofulvin (GF) was used as the model drug compound, and the polymer films were evaluated in terms of their surface morphology, mechanical properties and in vitro drug release. In general, the release rates were best described by first-order and Hixson-Crowell kinetic models, and in a typical film containing 57% HPMC, 100% of GF was released within 50. min. © 2011 Elsevier B.V.

Despite the development of DNA profiling for criminal investigation, fingerprints remain the most common type of forensic evidence to be recovered from a crime scene. From the first identifications made at Scotland Yard in the early years of the 20th century, to the computerised storage and searching that is available now, the basic concept of making a fingerprint identification has not changed. Imperfections (or minutiae) in the pattern of ridge lines on the tips of fingers and on the palms provide the key to linking a fingerprint found at a crime scene (often referred to as a finger mark) to the fingerprint of an individual. Since its inception, many techniques have evolved to reveal finger marks, usually deposited in sweat, at the crime scene. Some, such as the use of a fine powder applied with a brush, are as old as fingerprinting itself and remain in use because they are simple and easy to use, and are effective at revealing invisible (or latent) finger marks. Today, the numerous techniques available are neatly summarised by the Home Office Centre for Applied Science and Technology in their Fingerprint Source Book, which is essential reading for any crime scene investigator. Generally, finger mark recovery techniques are arranged by reference to the surface (or substrate) on which the latent finger mark is deposited, with some substrates being historically problematic for latent finger mark recovery. One such substrate is the outer surface of spent brass shell casings, usually ejected from a firearm after firing. Often, at the scene of a crime involving the discharge of a fireman, these spent shell casings present the only physical evidence left by the offender, so their importance shouldn't be underestimated. Latent finger mark recovery from spent shell casings is difficult as the area of contact between the finger and the casing is limited due to the curvature of the casing and also because of the environmental extremes undergone by the casing during firing and ejection, which can all but obliterate latent finger marks. Following a serendipitous finding by researchers at Swansea University that rubbing a metal surface with a tissue does not necessarily remove the finger mark ridge minutiae, we started to investigate why this might be so – and, importantly, how the finger mark might be revealed. Through experimentation, we were able to show that the inorganic components present in fingerprint sweat, particularly chloride ions, were able to induce corrosion on the metal surface at the location of the finger mark deposit. Further, this corrosion was quite difficult to remove and remained even after washing the metal in warm soapy water to remove any trace of the original sweat deposit. Copper and its alloys (such as brass) were found to be very easily corroded by fingerprint sweat, which, potentially, makes this useful for finger mark recovery from spent brass shell casings. After further experimentation, a technique was devised that enabled a fine coloured powder to adhere preferentially to areas of corrosion on a brass disk, to which had been applied a large (about 2,500 V) electric potential. This powder adherence was developed to work with round brass shell casings, rather than a flat disk, and eventually commercialised. As might be expected, the main market for such technology lies outside the UK and since its development, has been used in many criminal cases, mainly in the US, to try and recover finger mark corrosion from spent brass shell casings. One positive aspect is that, because the corrosion is difficult to remove from the brass, the technique can be applied to casings that are many years old and relate to what are termed "cold cases". Fortunately, law enforcement agencies rarely destroy evidence – particularly from unsolved homicides – and these offences present ideal evidence for this technique. In 2015, the University of Leicester signed an agreement with Zhejiang Police College in China to collaborate in advancing forensic science research and teaching. An early result of this has been the joint development of an improvement in the way this technique works. Essentially, the electrically charged shell casing is now rotated in a bed of the powder, which makes the process easier than the original method of applying the powder directly to the casing. Why is this new development important? Well, as finger mark visualisation techniques that are quick, easy and effective are preferred, anything that makes the process easier to produce a positive result is to be welcomed. As the use of firearms in crime seems unlikely to diminish, this development offers law enforcement agencies a further opportunity to crack cases.
