Questions are swirling over the future of Egypt’s first science city, after the death of the Nobel laureate who made the project his legacy. The Zewail City of Science and Technology, a campus outside Cairo comprising a non-profit university and several research institutes, is named for the man who spearheaded it: Egyptian-born US chemist Ahmed Zewail, the first Arab to win a science Nobel. But Zewail’s death at the age of 70 last week raises fresh doubts about the research hub's already precarious finances. The institute had relied heavily on Zewail’s star name and contacts to attract the support of scientific luminaries and millions of dollars in donations and government loans. It is now running out of money, has not yet raised enough cash to support a planned move to a new campus and will probably have to rely on more state support, say researchers working there. “Fundraising has always been a challenge, and I think it is likely to be affected by the loss of Dr Zewail in the short term,” says Sherif El-Khamisy, a molecular biologist at the University of Sheffield, UK, who is also director of Zewail City’s Center for Genomics. “But the logistical support envisaged from the state is expected to override the initial fear or uncertainty.” Uncertainty has plagued Zewail City since its inception. While working at the California Institute of Technology in Pasadena, Zewail proposed in 1999 to found the university and technology hub near Cairo as a flagship science project, essential for Egypt’s research development. But it was not until 2011 that the institute launched — a delay that Zewail has ascribed to political instability and bureaucracy. The young university was quickly plunged into controversy, after Egypt's first not-for-profit private research institution, Nile University — also outside Cairo — argued that it owned some of the buildings gifted to the science city. Nile University ultimately won the legal dispute — although it has allowed researchers from Zewail City to stay on in its buildings until a new campus is complete. Zewail City began accepting students in 2013; it currently has more 500 students and 150 academic professors and researchers. The first class of students will graduate next year, many of whom have received scholarships to cover their tuition fees. The project’s new campus is expected to be finished in 2019, at a cost of at least US$450 million; a first phase should be complete by July 2017, when many faculty and students are to move there. But Zewail City hasn’t raised enough money to finish even its first phase, says Sherif Fouad, a spokesperson for the institute. To pay for scholarships and campus construction, it has almost used up the 700 million Egyptian pounds (around US$80 million) raised from donors; its other funding comes in the form of a 1-billion-Egyptian-pound loan from the ministry of defence, which ultimately must be paid back. A shaky economy and the widely expected devaluation of Egypt’s currency is not helping matters. El-Khamisy and others affiliated with the institute say they are hopeful that it will survive — not least because it has the verbal backing of Egypt’s president, Abdel Fattah el-Sisi. In a speech on 6 August after Zewail’s death, el-Sisi asked Egyptians to continue to donate to the city, but vowed that Egypt’s armed forces — whose engineers are building the new campus — would finish construction even if no more money comes through. “The president’s speech was very reassuring for us all that Zewail City remains a priority for the government and is considered one of Egypt’s national projects,” says Fouad. It is likely that Egypt’s government will ultimately need to step in with support, says Salah Obayya, a physicist who is currently acting chairman of Zewail City until a replacement for Zewail is elected. How the state deals with that intervention could affect whether the institute can maintain the support of scientists whom Zewail sought to attract, says Ibrahim el-Sherbiny, joint director of the institute’s Center for Materials Science. “If they feel the reassurance on the ground, they will remain and attract others because they loved Dr Zewail, and I am sure they would love to support him after his death,” he says. Zewail City enjoys an unusual autonomy: unlike other Egyptian state-sponsored institutions, it has been granted a decree that allows the campus to outline its own structure and governance, guaranteeing its independence from the education ministry. Obayya says that he does not expect such autonomy to be affected by closer government intervention. At a meeting on 8 August, Zewail City’s board of directors vowed that their pioneer’s “national mission” would carry on. British-Egyptian cardiac surgeon Magdi Yacoub of Imperial College London is widely tipped to take Zewail’s place at the head of the project, says Fouad. “If Sir Magdi Yacoub is chosen to run the city, it will give the project the needed stability to soldier on,” says Sherif Sedky, a physicist and former academic president of Zewail City, who is now provost of the American University in Cairo.

In this paper, we consider a wireless communication scenario with multiple source-destination pairs communicating through several cooperative amplify-and-forward relay terminals. The relays are equipped with multiple antennas that receive the source signals and transmit them to the destination nodes. We develop two iterative relay beamforming algorithms that can be applied in real-time. In both algorithms, the relay beamforming matrices are jointly designed by minimizing the received power at all the destination nodes while preserving the desired signal at each destination. The first algorithm requires the existence of a local processing center that computes the beamforming coefficients of all the relays. In the second algorithm, each relay can compute its beamforming coefficients locally with the help of some common information that is broadcasted from the other relays. This is achieved at the expense of enforcing the desired signal preservation constraints non-cooperatively. We provide two extensions of the proposed algorithms that allow the relays to control their transmission power and to modify the quality of service provided to different sources. Simulation results are presented validating the ability of the proposed algorithms to perform their beamforming tasks efficiently and to track rapid changes in the operating environment. © 2010 IEEE.


Bioinformatics services have been traditionally provided in the form of a web-server that is hosted at institutional infrastructure and serves multiple users. This model, however, is not flexible enough to cope with the increasing number of users, increasing data size, and new requirements in terms of speed and availability of service. The advent of cloud computing suggests a new service model that provides an efficient solution to these problems, based on the concepts of "resources-on-demand" and "pay-as-you-go". However, cloud computing has not yet been introduced within bioinformatics servers due to the lack of usage scenarios and software layers that address the requirements of the bioinformatics domain. In this paper, we provide different use case scenarios for providing cloud computing based services, considering both the technical and financial aspects of the cloud computing service model. These scenarios are for individual users seeking computational power as well as bioinformatics service providers aiming at provision of personalized bioinformatics services to their users. We also present elasticHPC, a software package and a library that facilitates the use of high performance cloud computing resources in general and the implementation of the suggested bioinformatics scenarios in particular. Concrete examples that demonstrate the suggested use case scenarios with whole bioinformatics servers and major sequence analysis tools like BLAST are presented. Experimental results with large datasets are also included to show the advantages of the cloud model. Our use case scenarios and the elasticHPC package are steps towards the provision of cloud based bioinformatics services, which would help in overcoming the data challenge of recent biological research.

In this work, a novel active shape model (ASM) paradigm is proposed to segment the right ventricle (RV) in cardiac magnetic resonance image sequences. The proposed paradigm includes modifications to two fundamental steps in the ASM algorithm. The first modification includes employing the 2D-principal component analysis (PCA) to capture the inter-profile relations among shape's neighboring landmarks and then model the inter-profile variations between the training set. The second modification is based on using a multi-stage searching algorithm to find the best profile match based on the best maintained profile's relations and thus the best shape fitting in an iterative manner. The developed methods are validated using a database of short axis cine bright blood MRI images for 30 subjects with total of 90 images. Our results show that the segmentation error can be reduced by about 0.4 mm and contour overlap increased by about 4% compared to the classical ASM technique with paired Student's t-test indicates statistical significance to a high degree for our results. Furthermore, comparison with literature shows that the proposed method decreases the RV segmentation error significantly.

An interference alignment (IA) scheme is presented that allows multiple opportunistic transmitters (secondary users) to use the same frequency band of a pre-existing primary link without generating any interference. The primary and secondary transmit-receive pairs are equipped with multiple antennas. Under power constraints on the primary transmitter, the rate of the primary user is maximized by water-filling on the singular values of its channel matrix leaving some eigen modes unused, and hence, the secondary users can align their transmitted signals to produce a number of interference-free dimensions at each secondary receiver without causing any interference to the primary user. An outer bound is developed on the degrees of freedom (DoF) of the secondary users. In the case of a symmetric secondary network with time-varying channel coefficients having $M$ antennas at each node and operating in the presence of a primary link with $d0 active eigen modes, a precoding scheme is presented for the secondary transmitters that can asymptotically achieve the available (M-d0)+/2DoF per secondary user. An iterative algorithm is also presented that utilizes channel reciprocity to achieve the proposed cognitive IA scheme. For a cognitive 3-user secondary network with constant channel coefficients, a novel closed-form solution is derived for the precoding matrices of the secondary users. © 2011 IEEE.

This paper presents a case for adopting agent-based modeling (ABM) as a framework for representing the complex interactions that occur within the context of urban infrastructure management. A generic ABM is proposed with four key agents namely; assets, users, operators and politicians. For each agent a set of generic attributes, actions and behaviors are defined. A detailed behavioral model is adapted from the service quality domain to represent customer perceptions and actions related to infrastructure level of service. An illustrative example of 20 assets and 50 user agents is simulated to demonstrate emergent agent behavior. The simulation highlights how varying user social and psychological behavior influences their response to consuming municipal infrastructure services. The model is evaluated by contrasting with a tradition Markov Decision Process framework. Results demonstrate how socio-technical aspects can be included within the complex decision making process of urban infrastructure management. © 2012 Elsevier B.V. All rights reserved.

Manufacturing systems evolution is afunction in multiple external and internal factors. With today's global awareness of environmental risks as well as the pressing needs to compete through efficiency, manufacturing systems are evolving into a new paradigm. This paper presents a system model for the new green manufacturing paradigm. The model captures various planning activities to migrate from a less green into a greener and more eco-efficient manufacturing. The various planning stages are accompanied by the required control metrics as well as various green tools in an open mixed architecture. The system model is demonstrated by an industrial case study. The proposed model is a comprehensive qualitative answer to the question of how to design and/or improve green manufacturing systems as well as a roadmap for future quantitative research to better evaluate this new paradigm. © 2011 Elsevier Ltd.

Optic Disc (OD) localization is an important pre-processing step that significantly simplifies subsequent segmentation of the OD and other retinal structures. Current OD localization techniques suffer from impractically-high computation times (few minutes per image). In this work, we present a fast technique that requires less than a second to localize the OD. The technique is based upon obtaining two projections of certain image features that encode the x- and y- coordinates of the OD. The resulting 1-D projections are then searched to determine the location of the OD. This avoids searching the 2-D image space and, thus, enhances the speed of the OD localization process. Image features such as retinal vessels orientation and the OD brightness are used in the current method. Four publicly-available databases, including STARE and DRIVE, are used to evaluate the proposed technique. The OD was successfully located in 330 images out of 340 images (97%) with an average computation time of 0.65 s. © 2010 IEEE.

One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell's responsiveness. The cell performance is compared under certain and uncertain external (demand) and internal (machine availability) conditions. Results showed that although lean cell is expected to be responsive to external demand with minimum waste, however, this was not the case under the considered uncertain conditions. The paper proposes an approach to mitigate this problem through employing dynamic capacity policy. Furthermore, the paper explores the effect of the delay associated with the proposed capacity policies and how they affect the lean cell performance. Finally, various recommendations are presented to better manage the dynamics of lean manufacturing systems. © 2012 Taylor & Francis.
