while ignoring income distribution and estimating aggregate demand generally leads to aggregation bias and thus, does not reflect households’ demand properly, yet aggregation bias is rarely considered in empirical demand studies and simply is ignored in most cases. the objective of the present study is to estimate aggregation bias in households’ demand for various types of meats and to evaluate...

protein aggregation is a serious problem for both biotechnology and cell biology. diseases such as prion misfolding, alzheimer’s, and other amyloidosis are phenomena for which protein aggregation in our living cells is of considerable relevance. human lysozyme has been shown to form amyloid fibrils in individuals suffering from nonneuropathic systemic amyloidosis, all of which have point mutati...

In-network data aggregation has been recently proposed as an effective means to reduce the number of messages exchanged in wireless sensor networks. Nodes of the network form an aggregation tree, in which parent nodes aggregate the values received from their children and propagate the result to their own parents. However, this schema provides little flexibility for the end-user to control the o...

The operation of hysterectomy has now become one of such common everyday occurrence, that in itself it would be superfluous to attempt to engage the interest of the Eellows of the Society in its description. But in an aggregation of cases there is much of clinical and pathological importance, and it is specially from this aspect that I feel warranted in bringing before you a resume of my experi...

a series of novel 2-aminopyrimidine and 2-substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against adp and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. none of the compounds showed satisfactory activity against the aggregation induced by adp. however, satisfac...

Request oriented sensor networks have stricter requirements than conventional event-driven or periodic report models. Therefore, in this paper we propose a minimum energy data aggregation (MEDA), which meets the requirements for request oriented sensor networks by exploiting a low power real-time scheduler, ondemand time synchronization, variable response frame structure, and adaptive retransmi...

Aggregating bandwidth from multiple radio access technologies (RATs) provides an opportunity for network providers to enhance network capacity. This is important for serving applications that require more bandwidth than a single RAT can offer. One of the important elements of bandwidth aggregation is the selection of a suitable set of RATs to achieve efficient aggregation. In this paper, we pro...

MPI-2’s one-sided communication interface has become prevalent in scientific applications. One of the important operations in a one sided model is read-modifywrite. MPI-2 semantics provide MPI Put, MPI Get and MPI Accumulate operations which can be used to implement the read-modify-write functionality. The different strategies yield varying performance benefits depending on the underlying one-s...

in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.

Data aggregation technology can effectively save network energy resource and storage resource so it is extensively applied in wireless sensor network. However, data aggregation technology also brings security problems and it demands that corresponding security schemes should be taken for precaution. Based on the requirement of the data aggregation security on WSN, combined with the features of ...
