Nonlinear optimisation method for image segmentation and noise reduction using geometrical intrinsic properties
No full textThis paper considers the optimisation of a nonlinear functional for image segmentation and noise reduction. Equations optimising this functional are derived and employed to detect edges using geometrical intrinsic properties such as metric and Riemann curvature tensor of a smooth differentiable surface approximating the original image. Images are then smoothed using a Helmholtz type partial differential equation. The proposed approach is shown to be very efficient and robust in the presence of noise, and the reported results demonstrate better performance than the conventional derivative based edge detectors
Al-Sharif Al-Radi: His Life and Poetry
No full textThe aim of this work is to study al-Sharif al-Radl, his life and poetry. The first part deals with the poet’s environment and life; the second with his poetry. Chapter I deals with the political conditions under which the poet lived. The purpose of the second chapter is to portray Al-Radl's social environment and its reflection in contemporary poetry. The third chapter describes the literary environment of Al-Radl's age at some length. The fourth chapter aims to study Al-Radl's life in detail. The factors which influenced his outlook and personality are discussed. An attempt is made to discern how far these factors affected his poetry. The second part of this work deals with Al-Radl's poetry itself. In Chapter V historical observations are made on Al-Radl's Diwan o in both manuscript and published forms. Chapter VI deals with his panegyrics. General remarks are made on eulogy in Arabic poetry. The content, form and development of Al-Radl's panegyrical odes are analysed. His Ikhwaniyyat receive special attention. Chapter VII deals with Al-Radl's self-praise its content and form. An endeavour is made to explore the Utopian world which the poet tried to portray, Al-Radl's elegies (Ch. VIII). their content, form and characteristics are reviewed. In addition, his dirges on women receive attention. Shi ism in Al-Radl’s poetry is discussed in Chapter IX, Al-Radl’s love-poetry (Ch. X) is discussed. His Hijaziyyat receive particular attention. It is claimed that Al-Radl’s produced in his Hijaaiyyat a poetical amalgam which contains some aspects of ‘Udhrite and ’Umarite poetry. Chapter II deals with Al-Radl's poetical technique. His theories of poetical composition and his comments on other poets are examined. A comparison is made between Al-Radl and other poets both previous and contemporary. Special attention is paid to al-Mutanabbi's influence. In Chapter XII there is a broad re-assessment of Al-Radl’s place in the history of Arabic poetry
A revised perspective on the evaluation of IT/IS investments using an evolutionary approach
No full textOn-going research into the evaluation of Information Technology (IT) / Information Systems (IS) projects has shown that aerospace and supply chain industries are needing to address the issue of effective project investment in order to gain technological and competitive advantage. The evaluative nature of the justification process requires a mapping of interrelated quantities to be optimised. Earlier work by the authors (Irani and Sharif 1997) has presented a theoretical functional model that describes these relationships in turn. By applying a fuzzy mapping to these variables, the optimisation of intangible relationships in the form of a Genetic Algorithm (GA) is proposed as a method for investment justification. This paper revises and reviews these key concepts and provides a recapitulation of this optimisation problem in terms of long-term strategy options and cost implications.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Skeletal Growth Estimation Using Radiographic Image Processing and Analysis
No full textAn automated knowledge-based vision system for skeletal growth estimation in children is reported in this paper. Images were obtained from hand radiographs of 32 male and 25 female children of age 1–16 yr. Phalanx bones were automatically localized and segmented using hierarchical inferences and active shape models, respectively. A number of shape descriptors were obtained from the segmented bone contour to quantify skeletal growth. From these descriptors, a feature vector was selected for a regression model and a Bayesian estimator. The estimation accuracy was 84% for females and 82% for males. This level of accuracy is comparable to that of expert pediatric radiologists, which suggests that the proposed approach has a potential application in pediatric medicine
اُردو نثری ترجمہ ہیر وارث شاہ از شریف کنجاہی کاتجزیاتی مطالعہ
No full textTranslations are playing an important role to convert the world into a global village. Urdu has a great ability to translate any kind of script. Heer Waris Shah is a famous poetic master piece of Punjabi language. Syed Waris Shah wrote it in 1766-67 and Sharif Kunjahi translated it into Urdu in 1991-92. It was the first Urdu translation of HeerWaris Shah. Shrif Kunjahi was an experienced translator and handled this difficult task very skillfully. This article is an over view of the abilities and translation skills of Sharif kunjahi. This article also discussed the Type and objectives of this translation
Using the markstrat business simulation to develop strategic management behaviours
No full textIt is well understood that experiential learning provides an incentive and impetus for accelerated learning, especially in humanities and business-focussed studies. ICT-based synthetic and virtual environments can provide a rich and varied context within which to achieve this. Specifically, this paper attempts to provide empirical, survey-based analysis of the application of a business simulation game, MarkStrat, on undergraduate and postgraduate programmes in this vein. The paper subsequently posits the pedagogic benefit of using such business simulation games for the development of strategic management behaviours across student sample populations and derives subsequent results to highlight associated learning behaviours
