One of the most important aspects of software project management is the estimation of cost and time required for running information system. Therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. Software cost estimation refers to the process of development requirement prediction of software system. Various kinds of effort estimation patter...

Website fingerprinting (WF) attacks, usually conducted with the help of a machine learning-based classifier, enable network eavesdropper to pinpoint which website user is accessing through inspection traffic patterns. These attacks have been shown succeed even when users browse Internet encrypted tunnels, e.g., Tor or VPNs. To assess security new defenses against WF recent works proposed featur...

nowadays, software cost estimation (sce) with machine learning techniques are more performance than other traditional techniques which were based on algorithmic techniques. in this paper, we present a new hybrid model of multi-layer perceptron (mlp) artificial neural network (ann) and ant colony optimization (aco) algorithm for high accuracy in sce called multilayer perceptron ant colony optimi...

tourism organizations have become one of the main users of the internet in recent years bysetting their own urban tourism websites. however, not all the websites are effective to promote their goals andobjectives. an effective evaluation of urban tourism websites can help organizations on how best to employ them.using the ictrt (information, communication, transaction, relationship and technica...

The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order to increase the accuracy of this process, estimation models have to be revised. The Construct...

In this paper, we present a novel twist on the Beowulf cluster — the Bladed Beowulf. Designed by RLX Technologies and integrated and configured at Los Alamos National Laboratory, our Bladed Beowulf consists of compute nodes made from commodity off-the-shelf parts mounted on motherboard blades measuring 14.7 00 4.7 0.58. Each motherboard blade (node) contains a 633-MHz Transmeta TM5600TMCPU, 256...

Background Ethiopia has implemented the Integrated Pharmaceutical Logistics System (IPLS) since 2009, under the Pharmaceutical Funds and Supplies Agency (PFSA). Although more than 5,000 healthcare workers have been trained on IPLS, staff attrition and expanding service delivery has required ongoing training. To address this, partners provide mainly in-service training (IST); although, recently,...

In developing countries undergoing liberalising economic reforms, there are typically local incumbents facing the loss of protection. Strategic lobbying by such firms for a price-capping regulatory regime is, under certain conditions, one way in which they can deter entry by competitors who are likely to be foreign firms. We show that a regulatory price can be set such that the net profit of th...

In this paper an efficient three- stage algorithm is developed for software production cost and time estimation. First stage includes a hybrid model composed of COCOMO and Function Points methods to increase estimation accuracy. Second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...
