Simple Search

This paper illustrates how a Prolog program, using chronological backtracking to find a solution in some search space, can be enhanced to perform intelligent backtracking. The enhancement crucially relies on the impurity of Prolog that allows a program to store information when a dead end is reached. To illustrate the technique, a simple search program is enhanced.

Broadcast Scheduling

Vehicular Adhoc Networks (VANET) are thought-about as a mainstay in Intelligent Transportation System (ITS). For an efficient vehicular Adhoc network, broadcasting i.e. sharing a safety related message across all vehicles and infrastructure throughout the network is pivotal. Hence an efficient TDMA based MAC protocol for VANETs would serve the purpose of broadcast scheduling. At the same time, high mobility, influential traffic density, and an altering network topology makes it strenuous to form an efficient broadcast schedule. In this paper an evolutionary approach has been chosen to solve the broadcast scheduling problem in VANETs. The paper focusses on identifying an optimal solution with minimal TDMA frames and increased transmissions. These two parameters are the converging factor for the evolutionary algorithms employed. The proposed approach uses an Adaptive Discrete Firefly Algorithm (ADFA) for solving the Broadcast Scheduling Problem (BSP). The results are compared with traditional evolutionary approaches such as Genetic Algorithm and Cuckoo search algorithm. A mathematical analysis to find the probability of achieving a time slot is done using Markov Chain analysis.

The Garden as Unfinished Narrative of the Good in C.S. Lewis’ Perelandra

Hortus Conclusus

In Lewis’ transposition of Milton’s Paradise to a distant world where Adam and Eve do not succumb to Satan, the structure of Eden is radically different from the enclosed garden familiar to most readers. In the novel Perelandra (1944), C.S. Lewis represents the Garden of Eden as an open and ‘shifting’ place. The new Garden of Eden, with Adam and Eve unfallen, is a place of indeterminate future, excitement, growth, and change, very unlike the static, safe, enclosed Garden—the hortus conclusus of traditional iconography—from which humanity is not just expelled but also, in some sense, escapes. The innovation is not in the theological underpinnings that Lewis claims to share with Milton but in the literary devices that make evil in Perelandra seem boring, dead-end, and repetitive, while goodness is the clear source of change and excitement.

The literary career and troubled life of Derwent Moultrie Coleridge (1828–80), Derwent Coleridge's eldest son (S. T. Coleridge's first grandson) has been critically overlooked. After a period of alcohol-related, reckless behaviour at Cambridge University, he was exiled to Australia in November 1850, lest he continue to dishonour his father and the Coleridge name. Despite struggling considerably, he quickly became part of an Australian literary circle and he often contributed poems to Sydney newspapers. This essay analyses the most biographical of his poems that was published in the Australian press, ‘The Loafer's Christmas’ (1871) – a hitherto unknown poem – looking, in particular, at the dialogues in which the poem engages with his family, especially S. T. Coleridge's ‘The Rime of the Ancient Mariner’. I also contextualise ‘The Loafer's Christmas’ within nineteenth-century Australian culture. Looking at issues of exile, idleness, addiction, family, home(lessness), and religious redemption, this essay explores the ways in which Derwent Moultrie's exile proved to be both a literary liberation and a dead end, trapping him between times and spaces, real and imaginary. In so doing, I show how the lost life and writings of Derwent Moultrie Coleridge can offer us new perspectives on the Coleridge legacy.
