DC-networks offer desirable properties for anonymous communication, but a practical implementation for large networks is challenging. Other approaches like Tor exist and are easier to use in large networks, but they do not provide strong anonymity. This thesis describes a design for a DC-network implementation that targets large networks. It does not offer new methods to counter attacks, but it...

The study employs data envelopment analysis to a panel of commercial banks operating in Pakistan for a period 2001 – 2008 in order to measure the technical efficiency of banks. Technical efficiency is then broken down into pure technical and scale components. We divide banks into three categories for analytical purposes: state owned banks, domestic private banks and foreign owned banks. We find...

The Cooperative Expendable Micro-Slice Servers (CEMS) project evaluates low cost, low power servers for high-scale internetservices using commodity, client-side components. It is a followon project to the 2007 CIDR paper Architecture for Modular Data Centers [11]. The goals of the CEMS project are to establish that low-cost, low-power servers produce better price/performance and better power/pe...

This paper investigates wage differentials between workers in subcontracting and non-subcontracting firms, using data from a recent survey of small manufacturing firms in Gujranwala, Pakistan. The paper finds that subcontracting workers receive a high wage premium and invokes efficiency wage arguments to explain this differential. The paper argues that due to a client/vendor monitoring problem ...

background: nowadays, healthcare systems are considered as important service sectors, and they are social development and welfare standards; hence the performance of this sector is highly important. evaluating performance is the first step of various departments to determine the efficiency of the healthcare system. in the meantime, diagnostic laboratories of hospitals play important roles as sp...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

A low-complexity orthogonal multiplierless approximation for the 16-point discrete cosine transform (DCT) was introduced. The proposed method was designed to possess a very low computational cost. A fast algorithm based on matrix factorization was proposed requiring only 60 additions. The proposed architecture outperforms classical and state-of-the-art algorithms when assessed as a tool for ima...
