We argue that a set of usability heuristics are needed for easy and quick evaluation of Captchas implementations. With this set of heuristics we contribute to sustain the Captcha Mantra: “Easy for humans, hard for machines”. In particular, the usability of Captcha schemes change radically when utilized on mobile environments. We are developing a set of heuristics for use by practitioners wishin...

Oligo(ethylene glycol)-linked light fluorous tags have been found to be optimal for conjugating to glycans for both high-yield enzymatic glycosylation reactions using one-pot multienzyme (OPME) systems and quick product purification using fluorous solid-phase extraction (FSPE) cartridges. The combination of OPME glycosylation systems and the FSPE cartridge purification scheme provides a highly ...

Quick Summary is an innovate implementation of an automatic document summarizer that inputs a document in the English language and evaluates each sentence. The scanner or evaluator determines criteria based on its grammatical structure and place in the paragraph. The program then asks the user to specify the number of sentences the person wishes to highlight. For example should the user ask to ...

We provide an overview of the evolution of routing from its origins, even before the ARPANET, to recent algorithms that provide some Quality of Service, focusing on unicast distributed routing algorithms. We start our scheme with shortest path routing and optimal routing and conclude it with constrained routing protocols as well as a quick review of Ad-Hoc Routing protocols. KeywordsBest-effort...

Abstract This is a digest of the work and research completed thus far in developing a progressive image transmission scheme. Efficient and quick communication of perceptually important image information is desired resulting in this research with wavelet and fractal techniques for the identification and extraction of perceptually important features. This is done with the final goal of interactiv...

Dirac sea corrections for bulk properties of finite nuclei are computed within a self-consistent scheme in the σ-ω model. The valence part is treated in the Hartree approximation whereas the sea contribution is evaluated semiclassically up to fourth order in h̄. Numerically, we find a quick convergence of the semiclassical expansion; the fourth order contributing much less than one percent to th...

We introduce a new way of computation of time dependent partial differential equations using hybrid method FEM in space and FDM in time domain and explicit computational scheme. The key idea is quick transformation of standard basis functions into new simple basis functions. This new way is used for better computational efficiency. We explain this way of computation on an example of elastodynam...

In this paper, we present an improved version of recently proposed Quick Hypervolume algorithm for calculating exact hypervolume of the space dominated by a set of d-dimensional points. This value is often used as a quality indicator in multiobjective evolutionary algorithms and other multiobjective metaheuristics and the efficiency of calculating this indicator is of crucial importance especia...

In this paper, a new scheme is proposed to allow the correspondent node to recognize the handover situation of the mobile node for vertical handovers using Mobile IPv6 signaling. The proposed scheme might be helpful for quick adjusting real-time traffics between two nodes when a drastic change in a bandwidth occurs due to vertical handovers in heterogeneous access networks that have a quite dif...
