CPAP Machine Performance and Altitude

Chest, 1995
STUDY RATIONALE AND OBJECTIVE: Sleep-disordered breathing is commonly treated with nasally applied continuous positive airway pressure (CPAP). Typically, pressures are titrated to pneumatically splint the airway to prevent its collapse in response to negative inspiratory pressure.

Thermal, rheological, wettability and hard machining performance of MoS2 and CaF2 based minimum quantity hybrid nano-green cutting fluids

Journal of Materials Processing Technology, 2019
Minimum quantity cutting fluids (MQCF) is an alternative for dry machining and flood cooling. However, use of MQCF is limited to mild machining conditions due to high heat generation during machining of hard materials.

Machining performance of high energy die-sinking electrical discharge machining on GH2132

, 2020
Superalloys are typical “difficult to machine” materials, which could be processed by electrical discharge machining (EDM). The studies about the machining performance of superalloys mainly concentrate on nickel-based superalloys and titanium superalloys.

Hard machining performance of indigenously developed green cutting fluid using flood cooling and minimum quantity cutting fluid

Journal of Cleaner Production, 2019
Cutting fluids play a vital part in turning process. Basically, these cutting fluids are made up of mineral oil (MO) and performance enhancing additives that are produced chemically. However, MO has adverse environmental effects and causes health hazards.

OPTIMIZATION OF CONNECTION MACHINE PERFORMANCE

International Journal of High Speed Computing, 1990
The Connection Machine CM-2 computer represents the state of the art in supercomputer performance at this time, with peak rates of over 20 Gflops in 32-bit precision. While theoretical peak rates are essentially never attained, remarkable performance is possible on real applications.

Performance of a Virtual Machine Monitor

1979
This paper describes the performance of a Virtual Machine Monitor. A Virtual Machine Monitor (VMM) is an operating system which executes on the native hardware and allows other (standard) operating systems to execute in an environment much like the environment an operating system provides for user programs.

Performance of Overload Control in Machine- to-Machine Wireless Networks

2018 IEEE Global Communications Conference (GLOBECOM), 2018
The diverse applications of machine-to-machine (M2M) communication are going to lead to exponential growth in M2M traffic. Associating with M2M deployment, a massive number of devices are expected to access the wireless network concurrently. Hence, a network congestion is likely to occur.

Machining performance of vegetable oil with phosphonium- and ammonium-based ionic liquids via MQL technique

Journal of Cleaner Production, 2019
Thermo-mechanical loads are the main factor that influences the tool wear and product surfaces during machining processes. Lubrication in metal cutting is an effective medium to reduce frictional forces and wear on the tool-workpiece interfaces.

Comparison of injection molding machine performance

Polymer Engineering & Science, 2005
AbstractA comprehensive study into the performance of 4 injection molding machines is reported, using identical mold, polymer, and processing conditions. Start‐up dynamics and process repeatability were directly compared across machine technologies. One servohydraulic, one proportional hydraulic and two servoelectric machines were used in the study ...

Performance parameters for parallel machines

1992
Performance modelling of a real application program which is able to run on a certain real machine begins with the development of abstract models of the application and of the machine. Time cost functions for the primitives of the abstract machine have to be determined which are based on performance and size parameters of the considered configuration ...
