OBJECTIVE Insulin pump therapy associated with continuous glucose monitoring has shown a positive clinical impact on diabetes control and reduction of hypoglycemia episodes. There are descriptions of the performance of this device in other populations, but its precision and accuracy in Colombia and Latin America are unknown, especially in the routine outpatient setting. METHODS Data from 33 t...

In this paper we study some problems related to grid n-ogons. A grid n-ogon is a n-vertex orthogonal simple polygon, with no collinear edges, that may be placed in a (n 2 ) × (n 2 ) square grid. We will present some problems and results related to a subclass of grid n-ogons, the Thin grid n-ogons, in particular a classification for theses subclass of polygons. We follow presenting the solution ...

The D-Grid reference installation is a test platform for the German grid initiative. The main task is to create the grid prototype for software and hardware components needed in the D-Grid community. For each grid-related task field different alternative middleware is included. With respect to changing demands from the community, new versions of the reference installation are released every six...

This paper proposes a new single phase transformerless Photovoltaic (PV) inverter for grid connected systems. It consists of six power switches, two diodes, one capacitor and filter at the output stage. The neutral of the grid is directly connected to the negative terminal of the source. This results in constant common mode voltage and zero leakage current. Model Predictive Controller (MPC) tec...

In this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. The system will be connected inparallel between the grid and load. The proposed system supplies all load power consumption(including active po...

We consider a grid network where nodes contain small buffers. A packet that faces a crowded buffer in its route will get extra latency and may be dropped. In this paper, we propose a novel flow control protocol called RFCC for grid networks. RFCC tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

OBJECTIVE To determine the visual outcome of laser treatment in diabetic retinopathy. DESIGN Prospective, non-comparative case series. MATERIALS AND METHODS A total of 80 eyes of 50 patients with diabetic retinopathy in different stages were photocoagulated using diode green laser. Focal laser only was given in 46 eyes and pan retinal photocoagulation only was given in 29 eyes while 3 eyes ...
