With the recent rapid revival of the GLONASS constellation, it is possible for the GLONASS system to provide Full Operational Capability (FOC) service before the end of 2011. CDMA signals are now additionally modulated onto the first GLONASS-K satellite which was launched on February 26, 2011. It is envisaged that GNSS users will benefit from more visible satellites, better precision and higher...

Research has demonstrated that receiver clock modeling can reduce the correlation coefficients among the parameters of receiver clock bias, station height and zenith tropospheric delay. This paper introduces the receiver clock modeling to GPS/GLONASS combined precise point positioning (PPP), aiming to better separate the receiver clock bias and station coordinates and therefore improve position...

The success rate of automatic transplanter seedling picking is affected by the harsh operating environment and reduced output accuracy opening closing positioning seedling-picking mechanism due to interference external environment. To solve such problems, paper proposes use an adaptive fuzzy PID control algorithm as positioning-control system mechanism. Based on theoretical analysis calculation...

We provide an evidence-based approach to managing patients with acute lung injury and acute respiratory distress syndrome (ARDS). We searched MEDLINE and the Cumulative Index to Nursing and Allied Health for randomized trials evaluating lung-protective ventilation strategies, inhaled nitric oxide, prone positioning, and late-phase corticosteroids for managing these patients, and for additional ...

To support processing and collaboration, every node in the network needs to know the identity and location of its neighbors. This can be easily obtained in a planned network and quite hard in ad hoe networks whose topology is constructed and updated in real time. Selflocation using GPS may not be feasible but an effective distributed positioning algorithm is to be used. The proposed technique i...

Background The Optical Surface Management System (OSMS) is a simple, fast, reproducible, and accurate solution for patient set-up and can minimize random day-to-day set-up errors. However, studies in breast cancer patients are rare. Objective To analyze 200 patient set-ups in 20 patients with breast cancer by comparing the OSMS with the conventional cone-beam computed tomography (CBCT). Met...

introduction:tapia’s syndrome is a rare complication of recurrent laryngeal and hypoglossal nerve paralysis due to anesthetic airway mismanagement or malpositioning of the patient’s head during surgery. case report:here we present a case of tapia's syndrome in a 22-year-old male after corrective jaw surgery under general anesthesia, with a long period of recovery, related to airway managem...
