In the user identification (UI) scheme for a multiple-access fading channel based on randomly generated (0, 1, -1)-signature code, previous studies used signature code over noisy adder channel, and only state information (USI) was decoded by decoder. However, considering communication model as compressed sensing process, it is possible to estimate coefficients while identifying users. this stud...

An identity based signature allows users to sign their documents using their private keys and the signature can be verified by any user by using the identity of the signer and public parameters of the system. This allows secure communication between the users without any exchange of certificates. An aggregate signature scheme is a digital signature scheme which allows aggregation of di erent si...

background: dietary risk factors constitute some of the leading risk factors for cardiovascular disease in iran. the current study reports the burden of ischemic heart disease (ihd) attributable to a low omega-3 fatty acids intake in iran using the data of the global burden of disease (gbd) study 2010. methods: we used data on iran for the years 1990, 2005, and 2010 derived from the gbd study c...

The Availability Based Tariff (ABT) mechanism has been introduced in Indian system mainly to ensure grid security and to deal with grid indiscipline prevailing in the system prior to its introduction. Unscheduled Interchange (UI) charge one of the components of ABT, acts a mechanism for regulating the grid frequency. At the same time, this mechanism offers opportunity to participants to exchang...

The results from the small scale application are encouraging. Our model successfully reproduces known behavior of the λ−switch on the basis of molecular level competition and resource constraints, without the need to assume protein-protein interactions between cI2 dimers and cI2 and RNA-polymerase. Even in the context of this well-known sub-system, however, few quantitative experimental results...

aims: this study aims to review the economic cost of childhood (0-18 years) unintentional injuries (ui) and focuses upon comparing the cost burden between developing and developed countries. methods: articles were selected from pubmed using the search words “economic cost”, “unintentional injuries” and “children”. nine articles were selected. results: studies in china focused upon cost to hospi...

background: this study uses data of the global burden of diseases (gbd) study 2010 to report death, disability-adjusted life year (dalys), years of life lived with disability (ylds) and years of life lost due to premature mortality (ylls), attributed to suboptimal breastfeeding by age and gender during 1990 to 2010 in iran. materials and methods:the gbd assessments were used, together with esti...

Nowadays, voice assistants help users complete tasks on the smartphone with commands, replacing traditional touchscreen interactions when such are inhibited. However, usability of those tools remains moderate due to problems in understanding rich language variations human along efficiency and comprehensibility issues. Therefore, we introduce Voicify, an Android virtual assistant that allows int...

• U0 = V which is a subspace of R. Thus, U0 is a vector space • Assume that Ui is a vector space, for i ≥ 0. We will show that Ui+1 = Ui ∩A Ui is also a vector space. From the definition of Ui+1, it is clear that Ui+1 ⊆ Ui. We also have: – For any x, y ∈ Ui+1: x, y ∈ Ui ∩ A Ui, thus x ∈ Ui and x ∈ A Ui ⇒ Ax ∈ Ui. Similarly, y ∈ Ui and Ay ∈ Ui. Since Ui is a vector space, it follows that x + y ∈...
