Query optimization in microsoft SQL server PDW

Proceedings of the 2012 ACM SIGMOD International Conference on Management of Data, 2012
In recent years, Massively Parallel Processors have increasingly been used to manage and query vast amounts of data. Dramatic performance improvements are achieved through distributed execution of queries across many nodes. Query optimization for such system is a challenging and important problem.In this paper we describe the Query Optimizer inside the

Comprehensive method to reduce PDW in arrayed-waveguide grating

Optical Fiber Communication Conference and Exhibit, 2003
Stress induced birefringence is the source of polarisation dependent wavelength (PDW) in AWGs. The reduction of thermally induced residual stress (the effective stress of the AWG device and the stress balance on the core and surrounding cladding) during the waveguide fabrication process is the key to minimizing PDW.

Definition of reference ranges for the platelet distribution width (PDW): a local need

cclm, 2009
AbstractBackground:Automated hematological analyzers have contributed to more precise and faster results. They also make it possible to measure several blood cell parameters automatically. Among the parameters provided, platelet indices are probably the most ignored by clinical laboratories due to the difficulty of standardization, as well as being ...

The Development of the Police Department Wellness Survey (PDWS)

Police officers dedicate their careers to serving and protecting the communities they work in. Research is finding that the intensity of demands put on their mental health has turned suicide rates amongst police officers is at critical levels and has been declared by experts to be a ‘pandemic’ in the population (Wylie, 2020).

The Value of RDW, PDW, and Immunoglobulin E in the Clinical Diagnosis of Pediatric Asthma

Journal of Clinical and Nursing Research
Objective: To observe and explore the value of the combined application of red blood cell distribution width (RDW), platelet distribution width (PDW), and immunoglobulin E (IgE) in the process of clinical diagnosis of children with asthma. Methods: Fifty-five children with suspected asthma were admitted to the hospital from July 2021 to July 2023. They
