In this paper, we propose a scheme that dynamically adjusts the slow start threshold (ssthresh) of TCP. The ssthresh estimation is used to set an appropriate ssthresh. A good ssthresh would improve the transmission performance of TCP. For the congestion avoidance state, we present a mechanism that probes the available bandwidth. We adjust the congestion window size (cwnd) appropriately by obser...

This work presents a categorization scheme for IT strategies. Because of the increased importance of IT for every function within organizations especially enterprises must have an IT strategy. Thereby IT strategies have different objectives and can be distinguished between intentionally developed plans for the future and patterns from the past evolving from actions of the organization. Based on...

In this paper, we address the problem of active packet routing and forwarding in an active IP network involving both legacy IP routers and active capable routers. We first argue that any traditional routing scheme does not work well in active networks. We then give a formulation of a generalized active routing problem and propose an efficient routing scheme based on the formulation. The scheme ...

The transfer matrix of a solid described by the stacking of principal layers is obtained by an iterative procedure which takes into account 2" layers after n iterations, in contrast to usual schemes where each iteration includes just one more layer. The Green function and density of states at the surface of the corresponding semi-infinite crystal are then given by well known formulae in terms o...

BACKGROUND The finite volume solver Fluent (Lebanon, NH, USA) is a computational fluid dynamics software employed to analyse biological mass-transport in the vasculature. A principal consideration for computational modelling of blood-side mass-transport is convection-diffusion discretisation scheme selection. Due to numerous discretisation schemes available when developing a mass-transport nume...

In recent years there has been increasing attention towards digital rights. Therefore, this paper proposes a matrix barcode to verify image copyrights. The copyright text, Quick Response code (QR code), and watermarking techniques are used to achieve a hidden identification scheme implementing direct sequence spread spectrum (DSSS) and modulation of the modified code division multiple access (M...

A fuzzy-control-based Quick Response (QR) reorder scheme for seasonal apparel is being developed. The fuzzy-control scheme uses Mamdani inference logic. A stochastic computer simulation model of the apparel-retailing process is employed to evaluate the performance of the proposed scheme vis-a-vis that of existing approaches. Background “Quick Response” (QR) for apparel retailing refers to the a...

For enterprises of all sizes, sustainability is becoming increasingly important. Accordingly, there has been a noticeable increase in academic literature in the field of sustainability management and related tools and approaches. While the academic and practical contributions are growing in this field, it appears that literature has overlooked certain type of enterprise, namely the microenterpr...

Chiron is a derivative of von-Neumann-Bernays-Gödel (nbg) set theory that is intended to be a practical, general-purpose logic for mechanizing mathematics. It supports several reasoning paradigms by integrating nbg set theory with elements of type theory, a scheme for handling undefinedness, and a facility for reasoning about the syntax of expressions. This paper gives a quick, informal present...
