In this position paper we explore how new capabilities of mobile devices could be used to setup distributed multi-user mobile applications with potentially high interest for end users. We describe an example of such an application by transposing Internet social network trends and principles to a mobile ad hoc environment. Then we present a tentative design and implementation sketch of this appl...

We describe two simple methods that can be used together or alone to localize brain convexity lesions. These methods are based on computerized tomography or magnetic resonance imaging to calculate the position of a given lesion under the skin and help neurosurgeons to plan their surgical approaches. Using spatial fixed points traced on the radiological scans and transposing them to the skin sca...

Emergency surgical repair for acute traumatic aortic ruptures has been associated with a high peri-procedural mortality rate. Endovascular stent-grafting, as a less invasive procedure, has shown encouraging results. This report describes a patient with a short landing zone, who was treated by transposing the supra-aortic branch without sternotomy, followed by covered stent-grafting with an exte...

In this article, a fast algorithm is developed to compute two-dimensional convolutions of an array of d 1· d 2 complex number points, where d 2 = 2 and d 1 = 2m -r+ 1 for some I ,.; r ,.; m. This new algorithm requires fewer multiplications and about the same number of additions as the conventional FFT method for computing the two-dimensional convolution. It also has the advantage that the oper...

Pror.*^ ? ns' interposition operation for prolapse ?aentia. The principle of the Watkins' operation is based on separating the bladder from the anterior wall of the nterus and transposing its attachment to the posterior wall, so that the uterus is left in a position to support the entire bladder. Watkins performed his first operation in 1898. Several modifications, notably that of Wertheim, hav...

A high speed and reduced-area 2-D discrete wavelet transform (2-D DWT) architecture is proposed and the design is simulated. Initially modifications are made to the lifting scheme, and the intermediate results are recombined and stored to reduce the number of pipelining stages. The architecture uses three basic 1D-DWT image processing elements. The proposed architecture only requires less regis...

Homologous recombination at the bacterial transposon Tn7 donor site is stimulated 10-fold when Tn7 is activated to transpose at high frequency in RecD- Escherichia coli, where recombination is focused near the ends of double-chain breaks. This is observed as an increase in recombination between two lacZ heteroalleles when one copy of lacZ carries within it a Tn7 that is transposing at high freq...

Functional transposition is a technique for converting relations into functions aimed at developing the relational algebra via the algebra of functions. This paper attempts to develop a basis for generic transposition. Two instances of this construction are considered, one applicable to any relation and the other applicable to simple relations only. Our illustration of the usefulness of the gen...
