    Pechukas-Yukawa approach to the evolution of the quantum state of a parametrically perturbed system

    We consider the evolution of a quantum state of a Hamiltonian which is parametrically perturbed via a term proportional to the adiabatic parameter \lambda (t). Starting with the Pechukas-Yukawa mapping of the energy eigenvalues evolution on a generalised Calogero-Sutherland model of 1D classical gas, we consider the adiabatic approximation with two different expansions of the quantum state in powers of d\lambda/dt and compare them with a direct numerical simulation. We show that one of these expansions (Magnus series) is especially convenient for the description of non-adiabatic evolution of the system. Applying the expansion to the exact cover 3-satisfability problem, we obtain the occupation dynamics which provides insight on the population of states.Comment: 12 pages, 6 figure

    Pattern recognition in histopathological image analysis requires new techniques and methods. Various techniques have been presented and some state of the art techniques have been applied to complex textural data in histological images. In this paper, we compare the novel Adaptive Discriminant Wavelet Packet Transform (ADWPT) with a few prominent techniques in texture analysis namely Local Binary Patterns (LBP), Grey Level Co-occurrence Matrices (GLCMs) and Gabor Transforms. We show that ADWPT is a better technique for Meningioma subtype classification and produces classification accuracies of as high as 90%

    This article focuses on four important factors: Assessment, Curriculum and Text Books’ Policy, Teachers for quality education and Education and management, as formulated by Education and Literacy Department of Sindh Government. Open poll discussions and views given by educationists and experts were taken. All the views have been summarized for consideration by all concerned. Chief Minister Sindh, Arbab Ghulam Rahim, Javed Hussain, Education Minister, Hamida Khoro and Education Secretary to Government of Sindh, Ghulam Ali Pasha also shared their opinions on the new Education Policy and Government’s intention to ensure quality education in Sindh Province. The purpose of this article is to review and summarize the views presented in the Education Conference and reach fruitful conclusions. The implications are also made keeping in mind the targets of New Millennium Development Goals (NMDGs).Assessment, Curriculum and Text Book Policy, Education and Management, Literacy

    Family Types, Authority Structure and Women Workers in Sindh Labor Force: Problems and Prospects

    The development of a society is virtually dependent upon the quality of human resources both male and female, the changing pattern of economic and social development of world societies irrespective of their level of development, necessitates and equal advancement of both the social segments. The numerical reality that women constitute about nearly half of the total population of Sindh ideally assigns to them equal participating role in the economic life of the province. However, like other developing countries, women’s role in Sindh as an active worker-producer of goods and services has not been duly recognized by this male dominated society. With the objective of ensuring increased participation of women, clear-cut guidelines about integrating women in the development process and defining their roles are still lacking in Sindh. The present study is a step in the direction of bridging the gap of information about female labor force participation of Sindh in different, activity rates, industry group, occupation group and employment status in 1981 and 1998 population census. The most important conclusion that emerges from this study is that though percentage of women labor force in different, activities, industry group, occupation group and employment status has mostly increased in 1998 as compared to 1981, but being nearly half of the population this increase is still very low.Family, Authority, Problems, Female, Labor Force, Sindh

    Contemporary Issues in Current Account Operations in Pakistani IBs - Sharia Compliant Solution

    Full text link
    Contemporary Sharia scholars have three stances about the Current Account Operations in Pakistani Islamic Banks (IBs) i.e., (i) Ijarah based contract (ii) Wadi'ah based contract, and (iii) Qard based contract. This paper is an attempt to delve into the root causes of the differences of scholars and to find the Sharia-compliant solution acceptable for all. Descriptive as well as applied approaches are used in this paper. Clearing of ambiguity on this issue may result in twofold benefits: from the public point of view, it would satisfy practising Muslims which may result in form of huge deposits in this account (ii) from IBs viewpoint the Current Account is a bonus deposit
