Local features up to now are often mentioned in the meaning of interest points. A patch around each point is formed to compute descriptors or feature vectors. Therefore, in order to satisfy different invariant imaging conditions such as scales and viewpoints, an input image is often represented in a scale-space, i.e. size of patches are defined by their corresponding scales. Our proposed techni...

For general time-dependent local volatility models, we propose new approximation formulas for the price of call options. This extends previous results of [BGM10b] where stochastic expansions combined with Malliavin calculus were performed to obtain approximation formulas based on the local volatility At The Money. Here, we derive alternative expansions involving the local volatility at strike. ...

Recently, a new search strategy called configuration checking (CC) was proposed, for handling the cycling problem of local search. The CC strategy was used to improve the EWLS algorithm, a state-of-the-art local search for Minimum Vertex Cover (MVC). In this paper, we use this strategy to develop a local search algorithm for SAT called CWcc and a local search algorithm for weighted MAX-2-SAT ca...

Recent scholarship from political science, urban studies, and sociology conceptualizes the city as a space of decentralized democracy – a view emphasizing localization, participation, difference, and anti-hierarchical organizational form. Instead of conceiving the city as a place of atomized individuals and a locale for market exchange, this alternative framework recognizes the city‟s role as “...

The present study aimed to investigate the generic organization of research article introductions in local Iranian and international journals in English for Specific Purposes, English for General Purposes, and Discourse Analysis. Overall, 120 published articles were selected from the established journals representing the above subdisciplines. Each subdiscipline was represented by 20 local and 2...

We revisit the classical local Expected Utility analysis of Machina [30] and show which is its global behavioral foundation, as an illustration, we compute the local utilities for the Prospect Theory model. JEL classi…cation: D81 Keywords: Local utilities, Risk aversion, Multi–utility representation, Prospect theory 1 Introduction The seminal paper of Machina [30] showed that the global risk av...

Small interfering RNA (siRNA) functions through pairing with specific mRNA sequences and results in the mRNA's degradation. It is a potential therapeutic approach for many diseases caused by altered gene expression. The delivery of siRNA is still a major problem due to its rapid degradation in the circulation. Various strategies have been proposed to help with the cellular uptake of siRNA and s...

Installed and working at laboratories in Salt River near Groote Schuur Hospital and at Tygerberg Hospital by late August last year, the adapted Lodox machines are causing major excitement among the country’s forensic experts. Dubbed the ‘ForenScan’ by staff at the Salt River forensic pathology laboratory, the low-dose radiography equipment is accelerating criminal investigations, enabling fast ...

We consider the concept of a local set of inference rules. A local rule set can be automatically transformed into a rule set for which bottom up evaluation terminates in polynomial time. The local rule set transformation gives polynomial time evaluation strategies for a large variety of rule sets that can not be given terminating evaluation strategies by any other known automatic technique. Thi...
