Two transient plays: A streetcar named desire and camino real
Frank Bradley
© 2002 by Robert F. Gross. Critics have made much of the similarities and resonances between Anton Chekhov’s and Tennessee Williams’s plays the qualities of lyricism, poignancy, the bittersweet vision of life, the resemblances among certain characters in the plays, and a basic humanity shared by the writers. An opportunity for comparing these two playwrights in detail is provided by the 1997 publication of Williams’s The Notebook of Trigorin, subtitled ‘a free adaptation of Chekhov’s ‘The Seagull’. Williams’s focus on sex and age continues in Masha and Medvedenko’s discussion of whether Arkadina and Trigorin are lovers or just traveling companions something which would have been understood in Chekhov’s culture and the fact that in Notebook Trigorin is made closer in age to Treplev than to Arkadina. Notebook is a bleakly funny, wonderfully gothic and even grotesque melodrama and must be taken on its own terms, separated from comparison with its source of inspiration.

Structural deterioration prediction modeling for coastal protection structures in alexandria eastern harbor
Ayman El Hakea, Soliman Abu-Samra, Ossama Hosny, and Hesham Osman
Limited research has been carried out on artificial-intelligence-based deterioration modeling for coastal structures. An asset inventory database (AID) for Alexandria's Eastern Harbor coastal assets was developed. Established visual inspection and condition rating procedures were followed to obtain a current structural condition index (SI) and a structural condition matrix (SCM) for each structure, considering a single inspection point. SIs and SCMs are classified into severity ranges. Taking the age of structure into account, transition probabilities between each of the deterioration severity ranges were calculated using backward analysis. Such probabilities then were utilized to formulate the structure's Markov- Chain (MC) transition probability matrix, enabling the prediction of future deterioration in case of a no-action policy. Furthermore, an artificial neural network (ANN) model was constructed using the same backward analysis concept. Comparing the MC and the ANN deterioration forecasts up to year 2050 for the same structures, the results showed very close deterioration trends with an error margin ranging between 5% and 12%. It was concluded that the stochastic MC-based deterioration modeling was more accurate in simulating the deterioration of structures between their year of construction and present. The deterministic ANN model showed promising capability of deterioration prediction depending on the quality of the structure's design data, historical records, and environmental conditions. © 2014 American Society of Civil Engineers.

Low-power all-digital manchester-encoding-based high-speed serdes transceiver for on-chip networks
Abdelrahman H. Elsayed, Ramy N. Tadros, Maged Ghoneima, and Yehea Ismail
This paper proposes a new architecture that multiplexes both data and clock on serial links, reduces Inter symbol interference (ISI) by using a resistive termination technique, and uses two-level Manchester encoding to solve the reduced swing problem and enable the use of power efficient circuitry. Using this signaling scheme makes the system insensitive to jitter accumulation along the transmission line, and avoids the need for a power hungry clock and data recovery (CDR) circuit. A self-calibrating digital-delay line is also implemented inside the decoder to enable the system to operate efficiently across process, voltage and temperature variations. The proposed scheme is implemented for a 3mm long on-chip transmission line in TSMC 65nm technology and simulation results are presented. © 2014 IEEE.

Novel aluminum-carbon nanotubes composites for structural applications
Amal M. K. Esawi, E. Salama, and Y. Ibrahim
The development of aluminum-carbon nanotubes (Al-CNT) composites has seen a surge in interest following promising results reported by various groups. The latest enhancements achieved by the research group: an increase in tensile strength and Young's modulus of 69% and 23% respectively for Al-CNT composites with 5 wt. % MWCNT were accompanied by a reduction in ductility expected to limit the applications of these novel composites. This is currently being addressed through the use of (1) dual matrix approach in which the CNTs are embedded in a first matrix of aluminum powders which are consequently embedded in a second matrix of aluminum; (2) functionally-graded (FG) approach in which a gradual change in the composition of the CNT-reinforced regions is tailored so as to produce a design-efficient material with an ultra hard surface that gradually leads to a soft core. The two approaches aim at enhancing the formability of the material for wider industrial applications.

Optimization-based approach for organizing the bidding of nonserial repetitive projects
Ahmed Samer Ezeldin and Ahmed M. Alhady
In practice, the number of contracts and the categories of contractors to be called for bidding on nonserial repetitive projects under one major program often are estimated on the basis of intuition and experience. It may involve emotional reactions to existing surrounding conditions. Accordingly, the factors that form the possible different scenarios should be properly analyzed and evaluated. This paper introduces an analytical model that allows for decisions on the number of contracts and projects per contractor for different contractor categories within major construction infrastructure programs. These optimum decisions are reached using an integrated time and cost objective. Genetic algorithm has been employed for performing optimization. A computer-based model has been developed and validated. © 2014 American Society of Civil Engineers.

Seismic retrofit of shear critical beam-column joints in existing concrete buildings
Wael M. Hassan and A. A. Bilal
Shear deficient beam-column joints in existing concrete buildings are believed to have caused partial or total structural collapses during past earthquakes. These joints primarily lack joint transverse reinforcement. A recent NEES grand challenge project resulted in detailed assessment tools for the seismic vulnerability of beam-column joints in existing buildings; however, retrofit strategies were not suggested. The literature body includes various retrofit solutions for interior and exterior joints. However, most of these solutions are either very expensive or highly invasive. The intent of retrofit is usually to have deficient joints to conform to ACI 352 to allow for flexural yielding in the beam using minimal joint alteration. This paper presents a simple retrofitting method for existing exterior beam-column joints that aims to transfer the mode of failure from joint shear failure to a weak-beam-strong column one with no shear degradation in the joint. The retrofit solution is validated through an experimental program that consists of testing four exterior beam-column joint sub-assemblages.
