Association Between Symptomatic Knee Osteoarthritis and Target Glycemic Control in Individuals With Type 2 Diabetes

Arthritis Care &Research, EarlyView.
Objective Knee osteoarthritis (OA) commonly affects individuals with type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

Control performance standards based load-frequency controller considering redox flow batteries coordinate with interline power flow controller

Journal of Power Sources, 2012
Abstract This paper proposes a sophisticate application of redox flow batteries (RFB) coordinate with Interline Power Flow Controller (IPFC) for the improvement of Load Frequency Control (LFC) of a multiple units two- area power system. The Interline Power Flow Controller is to stabilize the frequency oscillations of the inter-area mode in the ...

Realization of direct flow control with load pressure compensation on a load control valve applied in overrunning load hydraulic systems

Flow Measurement and Instrumentation, 2017
Abstract This paper presents the realization of direct proportional flow control with load pressure compensation feature on a LCV (load control valve). Proportional flow control performance means the flow through the LCV is proportional to the pilot pressure in the control stroke.

Control variable adjustment in load flows

IEEE Transactions on Power Systems, 1988
A linear programming type approach is used to adjust all adjustable loadflow variables with respect to specified constraints. The technique is applicable to the Newton-coupled (and -decoupled) as well as the fast-decoupled load flows. The coordinated adjustment of all adjustable variables improves the convergence of the load-flow program and results in

Evaluating load flow capability with thermostically controllable building loads

2015 North American Power Symposium (NAPS), 2015
Through demand side management programs, buildings are increasingly being used to provide respite where generation inadequacies exist. Buildings are commonly dispatched as thermostatically controllable loads by adjusting internal temperature setpoints. Thermal load variations can be attributed to the HVAC equipment and are highly dependent on internal ...

Study on load frequency control using redox flow batteries

IEEE Power Engineering Society General Meeting, 2004., 2004
Summary form only given. Rechargeable batteries such as Redox flow, which are not aged by frequent charging and discharging, have a quick response equivalent to SMES and outstanding function during overload. The battery efficiency increases when the cycle period of charging/discharging becomes shorter.

Flow Control of Extreme Pressure Loads Associated with Flow Separation

Journal of Engineering Mechanics, 2016
AbstractActive flow control is applied at different locations over a surface-mounted prism to reduce extreme pressure coefficient and loads. Different control strategies including blowing, suction, and synthetic jets are evaluated. The full unsteady Navier–Stokes equations are solved to determine the pressure coefficients.

Control setting of unified power flow controllers through a robust load flow calculation

IEE Proceedings - Generation, Transmission and Distribution, 1999
The unified power flow controller (UPFC) provides a promising means to control power flow in modern power systems. Essentially, the performance depends on proper control setting achievable through a power flow analysis program. The paper presents a reliable method to meet the requirements by developing a Newton–Raphson based load flow calculation ...
