In Ciphertext Policy Attribute-Based Encryption (CP-ABE) system, a set of attributes is associated with the private keys of each user. Also, the ciphertext is attached with a policy which is defined over that set of attributes. A user can decrypt the ciphertext if the ciphertext’s policy is satisfied by the attributes associated hith her private key. Traditional CP-ABE schemes, based on number ...

AIM The aim of this study was to investigate the effects of manual and mechanical lymph drainage on the bioelectrical composition of body tissues of patients with lymphoedema of the lower limbs. METHOD Twenty-one patients with lymphoedema of one leg were evaluated using single frequency bioelectrical impedance with four electrodes (SF-BIA4) immediately before and after a combination of manual...

introduction: better use of water and soil resources in paddy fields, increase in rice production and farmer's income, installation of subsurface drainage system is necessary. the main goalof these systems, are aeration conditions improvement prevention of water logging, yield increase, land use increase and multiuse of the land. in different countries, installation of subsurface drainage cause...

a typical iranians carbonate matrix block surrounded by an open fracture was modelled in order to understand the fracture-matrix interaction and how to model the interaction best. this was modelled by using a fine-scaled eclipse model in the single porosity mode . the model was extended to a stack of 6 matrix blocks to understand block-to-block interaction under gas injection scenarios. results...

This article examines annihilators in the skew polynomial ring $R[x;alpha,delta]$. A ring is strongly right $AB$ if everynon-zero right annihilator is bounded. In this paper, we introduce and investigate a particular class of McCoy rings which satisfy Property ($A$) and the conditions asked by P.P. Nielsen. We assume that $R$ is an ($alpha$,$delta$)-compatible ring, and prove that, if $R$ is ni...

Abstract Recent severe droughts, extreme floods, and increasing differences between seasonal high low flows on the Amazon River may represent a twenty-first-century increase in amplitude of hydrologic cycle over Basin. These precipitation streamflow changes have arisen from natural ocean–atmospheric variability, deforestation within drainage basin River, or anthropogenic climate change. Tree-ri...

Enhanced water use efficiency (WUE) is the key to sustainable agriculture in arid regions. The installation of capillary barriers (CB) has been suggested as one potential solutions. CB effects are observed between two soil layers with distinctly different hydraulic properties. A helps retain upper, relatively fine-textured layer, suppressing losses by deep drainage. However, retaining a shallow...

Asynchronous packet-switched interconnection networks with decentralized control are very appropriate for multiprocessing and data flow architectures. This paper presents performance models of single and multiple ring networks based on token ring, slotted ring, and register insertion ring protocols. The multiple ring networks have the advantages of being reliable, expandable, and cost effective...

Long term prediction of maximum water levels and combined sewer overflow (CSO) in drainage systems are associated with large uncertainties. Especially on rainfall inputs, parameters, and assessment of return periods. This paper proposes a Monte Carlo based methodology for stochastic prediction of both maximum water levels as well as CSO volumes based on operations of the urban drainage model MO...
