We study the transition matrix of a quantum walk on strongly regular graphs. It is proposed by Emms, Hancock, Severini and Wilson in 2006, that the spectrum of S+(U3), a matrix based on the amplitudes of walks in the quantum walk, distinguishes strongly regular graphs. We find the eigenvalues of S+(U) and S+(U2) for regular graphs and show that S+(U2) = S+(U)2 + I.

Digital Rights Management (DRM) is a technology that is being developed as a protection against the illegal distribution of copyrighted online material such as music or documents. DRM is a technology that lets rights holders safely distribute and sell their content online in a digital form. Different security mechanisms using DRM are introduced: EMMS by IBM Corp., Rights System by InterTrust Co...

Contactless card payments are being introduced around the world allowing customers to use a card to pay for small purchases by simply placing the card onto the Point of Sale terminal. Contactless transactions do not require verification of the cardholder’s PIN. However our research has found the redundant verify PIN functionality is present on the most commonly issued contactless credit and deb...

We study encrypted storage schemes where a client outsources data to an untrusted third-party server (such as cloud provider) while maintaining the ability privately query and dynamically update data. focus on multi-maps (EMMs), structured encryption (STE) scheme that stores pairs of label value tuples. EMMs allow queries labels return associated tuple. As responses are variable-length, subject...

Emerging interest of trading companies and hedge funds in mining social web has created new avenues for intelligent systems that make use of public opinion in driving investment decisions. It is well accepted that at high frequency trading, investors are tracking memes rising up in microblogging forums to count for the public behavior as an important feature while making short term investment d...

the local solid flow structure of gas-solid bubbling fluidized bed was investigated to identify and characterize the particle clusters. extensive mathematical calculations were carried out using the energy-minimization multi-scale (emms) approach for evaluating cluster properties including the velocity, the size and the void fraction of clusters in the dense phase of the bed. the results showed...

INTRODUCTION EMMS International and Emmanuel Hospital Association (EHA) implemented a pilot project, poverty reduction in India through palliative care (PRIPCare). A total of 129 interviews with patients and family enrolled in palliative care at three EHA hospitals (in Fatehpur, Lalitpur and Utraula) and staff discussions established that 66% of palliative care patients had lost livelihoods due...
