In this paper, a combined form of the Laplace transform method with the homotopy perturbation method is proposed to solve nonlinear equations. This method is called the homotopy perturbation transform method (HPTM). The nonlinear terms can be easily handled by the use of He’s polynomials. The proposed scheme finds the solution without any discretization or restrictive assumptions and avoids the...

Micro bubbles contrast agents registered in Europe are licensed only for cardiac, liver, breast and vascular applications (Sono-Vue®). Levovist® is also registered for vesi coureteric studies, but is practically no longer marketed, and is expected ultimately to be no longer available. Thus, lots of daily non-hepatic applications continue to be off-label and patients should be informed and must ...

In many multimedia applications, manipulation of video signals is preferably performed in the transform domain. Most of such operations are derived from their counterparts in the pixel domain. However, the rounding operation can not be obtained this way because it is a nonlinear operation. Without a proper treatment, it may become a major source of errors for multimedia systems, causing a misma...

Fibrous tows used in continuous fibre-reinforced polymers (CFRPs) deform geometrically during the production of composite products. The cross-sectional geometry of the tow is influenced by the load-induced deformation mechanisms. A study of the effect of two commonly assumed geometrical tow shapes on an equivalent pressure distribution in a tow-on-a-pin spreading arrangement was performed. The ...

This paper describes TopicLens, an interactive tool for exploring and recommending items within large corpora, based on both social metadata and topical associations. The system uses a hybrid visualization model that represents topics and content items side by side, allowing the user to actively explore recommendations rather than passively viewing them. The approach provides insight into the c...

Reliability assessment of upgraded legacy systems is an important problem in many safety-related industries. Some parts of the equipment used in the original design of such systems are either not available off-the-shelf (OTS) or have become extremely expensive as a result of being discontinued as mass production components. Maintaining a legacy system, therefore, demands using different OTS com...

1 Aim of This research is a Strategic analysis of seaports using multiple-criteria decision-making methods. At first, the strengths, weaknesses, opportunities and threats of Iranian seaports has been extracted from literature. Then, with respect to the importance concluded from LIKRET questionnaire distributed between experts (taking the views of the experts and specialist), five high importanc...

PROVIDING INFORMATION SERVICES TO REMOTE USERS is not a new concept for health sciences librarians. Most health care professionals practice in hospitals and clinics remote from a health sciences library. However, trends in today’s health care management systems, education initiatives, and the rise in consumerism challenge health sciences librarians to evaluate and extend their services more tha...

background: we investigated whether the lungheart ratio parameter (lhr) can be used to identify the optimum cut off frequency for butterworth filter in 99mtc myocardial spect imaging. materials and methods: this study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc c...
