Wireless sensor nodes are electronic devices capable of collecting, storing, and processing environmental information, and communicating with other sensor nodes through wireless communications. Hundreds or thousands of wireless sensor nodes deployed in a region of interest comprise a wireless sensor network (WSN), where all members cooperatively monitor the whole region, barriers, or targets (p...

The northwest arid region (NAR) of China, located in a cold region, has been experiencing extreme weather and runoff events for years. Summer (from June to August) is the main season for forming runoff in this region. Summer runoff is contributed by glacial runoff in addition to precipitation in glacierized basins. The upper basins of Hei River, Shule River, Kaidu River, and Manas River with di...

Expanded access to measles vaccination was among the most successful public health interventions of recent decades. All WHO regions currently target measles elimination by 2020, yet continued measles circulation makes that goal seem elusive. Using Demographic and Health Surveys with generalized additive models, we quantify spatial patterns of measles vaccination in ten contiguous countries in t...

The project focuses on examining the advantages of random verification with real examples. Random verification has two necessary parts, hierarchical testbench and coverage metrics. The layered testbench allows a verifier to improve the coverage by only modifying the randomization constraints at the highest level of abstraction. Although it might take a verifier more time to build such hierarchi...

public diplomacy is an idiom that has been noticed increasingly in last decades due to extension of internet and satellite news networks. this type of diplomacy be used related to influence, guidance and mobilization of public opinion for the aims of governmental and non-governmental agents. in this article, the author tried to give analytical answer to this question: in spite of being newest, ...

BACKGROUND In France, there are recommendations and reimbursements for human papillomavirus (HPV) vaccination but no HPV vaccination programs. Therefore, vaccination is largely determined by parents' initiative, which can lead to inequalities. The objective of this study was to determine the factors associated with poorer vaccination coverage rates in the most populated region of France. METH...

Deployment quality and cost are two conflicting aspects in wireless sensor networks. Random deployment, where the monitored field is covered by randomly and uniformly deployed sensor nodes, is an appropriate approach for large-scale network applications. However, their successful applications depend considerably on the deployment quality that uses the minimum number of sensors to achieve a desi...

In 1998, a series of regional cluster surveys (the ICONA Study) was conducted simultaneously in 19 out of the 20 regions in Italy to estimate the mandatory immunization coverage of children aged 12-24 months with oral poliovirus (OPV), diphtheria-tetanus (DT) and viral hepatitis B (HBV) vaccines, as well as optional immunization coverage with pertussis, measles and Haemophilus influenzae b (Hib...

BACKGROUND AND PURPOSE Acetabular retroversion may result in anterior acetabular over-coverage and posterior deficiency. It is unclear how standard radiographic measures of retroversion relate to measurements from 3D models, generated from volumetric CT data. We sought to: (1) compare 2D radiographic measurements between patients with acetabular retroversion and normal control subjects, (2) com...

This article presents a controlled experiment that compares the behavior of the testing techniques Statement Coverage and All Uses. The design of this experiment is typical for a factor with two alternatives. A total of 14 subjects carry out tests on a single program. The results indicate that there is enough statistical evidence to state that the cost of executing All Uses is higher than that ...
