Transit in corona product of graphs

The  transit of a vertex $v$ is ``the sum of the lengths of all shortest path with $v$ as an internal vertex'' and the transit index of a graph $G$  is the sum of the transit of all the vertices of it. In this paper we investigate transit of vertices in Corona product of graphs. An expression for transit of vertices in $G_1\circ G_2$, where $G_1$ and $G_2$ are arbitrary is derived. We also compute transit for vertices in $G_1\circ G_2$, in the case where $G_1$ is a path, a cycle, a star, a complete graph and a complete bipartite graph

Drift Free Variable Step Size Perturb and Observe MPPT Algorithm for Photovoltaic Systems Under Rapidly Increasing Insolation

The characteristic of a Photovoltaic (PV) panel is most affected by the incident solar insolation temperature, shading, and array configuration. Maximum power point tracking (MPPT) algorithms have an important role in harvesting maximum power from the solar PV arrays. Among the various MPPT methods Perturb and Observe (P&O) algorithm is the simple and efficient one. However, there will be a drift problem in case of increase in insolation. This drift will be more under rapid increase in insolation. To improve the speed of tracking the Maximum Power Point (MPP), a variable step size P&O (VSSPO) is developed. The drift problem will be more in the case of VSSPO as it will have a larger step size for an increase in insolation. In this paper, the maximum output power extraction from Solar PV under rapidly increasing insolation conditions by a drift free P&O (DFP&O) as well as drift free VSSPO (DFVSSPO) method is presented

A Message Passing Mechanism for Reconfigurable Communications Components Interconnected by Network-On-Chip Fabric

Abstract — One promising solution for interconnecting the reconfigurable communications components in a ER terminal is by network-on-chip fabric. In line with this direction, this paper proposes a message passing mechanism between the reconfigurable communications components in a terminal, in particular the process of injecting and ejecting messages into and out from the network-on-chip fabric. The proposed message passing system and procedures are important for the on chip operating environment: like supporting switching, routing functions

Platform Interconnect for a End to End Reconfigurable System

Abstract-- In a reconfigurable platform such as the E2R platform, interconnectivity and data transfer between the different components in the platform is a very important task. In this paper we propose the interconnect as a reconfigurable resource which can be configured to the data transfer needs of the platform. Functionalities of the components in the resource’s Logical Device Drivers are elaborated. Additionally, with a NoC based C-CEM as an example, initialization, data transfer and legacy data transfer transactions support are explained in detail
