Developing A Decision-Making Framework For Web Service Security Profiles: A Design-Science Paradigm, Mutaz Al-Debei, Bachar Alrouh, Gheorghita Ghinea 2009 The University of Jordan

Developing A Decision-Making Framework For Web Service Security Profiles: A Design-Science Paradigm, Mutaz Al-Debei, Bachar Alrouh, Gheorghita Ghinea

Dr. Mutaz M. Al-Debei

In this paper, we provide a novel analytical hierarchy process decision-making framework for Web service security profiles. This framework aids in solving the dilemma of which Web service security profile is most fitting in a particular situation. This is because the developed framework allows architects and developers to take informed decisions following a systematic and manageable approach. In developing the framework, we followed the design-science research paradigm within which we incorporated a number of laboratory experiments.


Model Omnibus Privacy Statute, Sam Han 2009 Burton Law FirmS

Model Omnibus Privacy Statute, Sam Han

Sam Han

One of today’s major concerns is how easily digital information can be copied and disseminated. Thus, when one’s private information becomes publicly available in digital format, that information can be readily duplicated and distributed across the globe within seconds. If the disseminated information includes credit card numbers or Social Security numbers, then there is a heightened exposure to identity theft and a host of other privacy-related crimes.

Given the existence of such a digital landmine, laws have been promulgated for various sectors (e.g., financial, healthcare, government, etc.) to protect personally-identifiable information. However, due to differing needs of ...

Seyed Reza nabavi

Coke formation reduction during naphtha pyrolysis was investigated using dimethyl disulfide (DMDS) and carbon disulfide (CS2) as inhibitors with different feed stocks. Different industrial nickel alloy steels such as stainless steel 304 and 316 (SS304, SS316), HP-modified (HP-mod) and HP-micro (HP-mic) were used as coupons in a quartz cylindrical reactor for coke formation studies. Coke formation significantly reduced in the presence of the additives or using feeds with more sulfur compounds. It was revealed that HP-mic alloy has the least coke deposition rate between other alloys. Scanning electron microscope (SEM) and energy dispersive X-ray analyzer (EDAX) were used for ...


Nanoindentation And Plasticity In Nanocrystalline Ni Nanowires: A Case Study In Size Effect Mitigation, Virginie Rollin, Frederic Sansoz 2009 Embry-Riddle Aeronautical University

Nanoindentation And Plasticity In Nanocrystalline Ni Nanowires: A Case Study In Size Effect Mitigation, Virginie Rollin, Frederic Sansoz

Virginie Rollin

We examine the processes of spherical indentation and tension in Ni nanowires and thin films containing random distributions of nanoscale grains by molecular dynamics simulations. It is shown that the resistance to nanoindentation of nanocrystalline Ni nanowires with diameters of 12 and 30 nm tends not to depend on the wire diameter and free surfaces, contrary to nanoindentation in single-crystalline nanowires. Accommodation of plastic deformation by grain boundary sliding suggests a mitigation strategy for sample boundary effects in nanoscale plasticity.


Dynamics Of Individual Molecules Of Linear Polyethylene Liquids Under Shear: Atomistic Simulation And Comparison With A Free-Draining Bead-Rod Chain, David Keffer, J. Kim, B. Edwards, B. Khomami 2009 University of Tennessee - Knoxville

Dynamics Of Individual Molecules Of Linear Polyethylene Liquids Under Shear: Atomistic Simulation And Comparison With A Free-Draining Bead-Rod Chain, David Keffer, J. Kim, B. Edwards, B. Khomami

David Keffer

Nonequilibrium molecular dynamics (NEMD) simulations of a dense liquid composed of linear polyethylene chains were performed to investigate the chain dynamics under shear. Brownian dynamics (BD) simulations of a freely jointed chain with equivalent contour length were also performed in the case of a dilute solution. This allowed for a close comparison of the chain dynamics of similar molecules for two very different types of liquids. Both simulations exhibited a distribution of the end-to-end vector, |Rete|, with Gaussian behavior at low Weissenberg number (Wi). At high Wi, the NEMD distribution was bimodal, with two peaks associated with rotation and ...


Applicability Of Membrane Reactor For Wgs Coal Derived Gas Processing: Simulation-Based Analysis, Krzysztof Gosiewski, Marek Tanczyk 2009 Polish Academy of Sciences - Institute of Chemical Engineering

Applicability Of Membrane Reactor For Wgs Coal Derived Gas Processing: Simulation-Based Analysis, Krzysztof Gosiewski, Marek Tanczyk

Krzysztof Gosiewski

Gas from coal gasification contains less hydrogen than from other syngas production methods. An attractive option is its further hydrogen enrichment for pure hydrogen production in a membrane reactor (MR) by Water Gas Shift (WGS). The goal of present study was to analyse MR fed with coal derived gas. Simulations for feasible membrane permeation parameters revealed that to get high conversion above 90% a relatively high S/C should be applied. Moreover, hydrogen recovery is in this case low (below 30%) so for hydrogen production an additional H2 separation after the MR should have been applied. The paper also shows ...

Axial Variation Of Mass Transfer Volumetric Coefficients In Bubble Column Bioreactors, Elizabeth León-Becerril, Rafael Maya-Yescas 2009 Centro de Investigación y Asistencia en Tecnología y Diseño del Estado de Jalisco A.C.

Axial Variation Of Mass Transfer Volumetric Coefficients In Bubble Column Bioreactors, Elizabeth León-Becerril, Rafael Maya-Yescas

Elizabeth León-Becerril

Bubble column bioreactors used to perform aerobic fermentations consist of a liquid medium containing microorganisms that uptake oxygen for metabolic reactions and gas bubbles that supply this oxygen. Mass transfer rate from gas to liquid phase is a crucial factor for the performance of bioreactors because microorganisms’ life and metabolic reactions depend directly upon it. The maximum transfer rate of oxygen from gas bubbles to the liquid medium is a function of two important parameters: the specific interfacial area and the mass transfer coefficient. These two parameters are lumped into the volumetric specific transfer coefficient. Since size of gas bubbles ...

Enacting Reliability: First Steps To Define Safety In The Vts Domain, Gesa Praetorius, Karl Bruno, Margareta Lützhöft

Gesa Praetorius

Although the term maritime safety is widely used in the maritime industry, there is no exact definition of what it entails. An explorative study of the VTS domain has been conducted to approach the concept of maritime safety. Four VTS centres were visited and 16 VTS operators were interviewed and observed to derive insights in how maritime safety is constructed from the perspective of an operator. Further, definitions of maritime safety by central actors in the maritime domain have been investigated through a literature study and several interviews. The results indicate that there is no common definition of the term ...

Rapid Prototyping Medical Models For Dysplastic Hip Orthopaedic Surgery, Noor Azuan

Noor Azuan

This research was carried out to show the usefulness of rapid prototyping (RP) medical models in dysplastic hip orthopaedic surgery. There is a lack of published information on the use of RP medical models in planning of dysplastic hip orthopaedic surgery, so this research was conducted to provide such information. Computed tomography (CT) of a patient with a dysplastic hip was used. Special medical software was used to prepare the three-dimensional model of the patient, which was then used to produce the RP medical models. These models were then given to the orthopaedic surgeons to plan for the dysplastic hip ...

A New Scheme For Detecting Misbehaving Zone Manager With Collaborative Honesty Neighbour, Farzaneh Pakzad, Marjan Rafsanjani, Arsham Saeid

Farzaneh Pakzad

In these years, many IDS (intrusion detection system) researches have tended to hierarchical and distributed architecture or hybrid architecture. However, in most of these architectures, monitoring nodes is supposed to be valid nodes in order to initiate IDS and response systems. So, if these nodes have been misbehavior nodes then they can send false information to other nodes or report an innocent node as destructive. In our proposed scheme, a hierarchical distributed model of multi-level intrusion detection is presented to overcome the shortcomings of existing intrusion detection techniques. The network is divided to zones with one zone manager which is ...


Sequential Sub-Problem Programming Strategies For Data Reconciliation And Parameter Estimation With Multiple Data Sets, Zhengjiang Zhang, Zhijiang Shao, Pengfei Jiang, Xi Chen, Yuhong Zhao, Jixin Qian 2009 Wenzhou University

Sequential Sub-Problem Programming Strategies For Data Reconciliation And Parameter Estimation With Multiple Data Sets, Zhengjiang Zhang, Zhijiang Shao, Pengfei Jiang, Xi Chen, Yuhong Zhao, Jixin Qian

Zhengjiang Zhang

Data reconciliation and parameter estimation (DRPE) is a key problem in real-time optimization. The dimensionality of the DRPE problem increases directly with the number of data sets, and the number of degrees of freedom in DRPE is very large. Therefore, solving a DRPE problem is very difficult. Sequential sub-problem programming strategies for data reconciliation and parameter estimation with multiple data sets are proposed in this paper. Based on the characteristics of a DRPE optimization problem, we construct a series of sub-problems depending on objective and model parameters. The solutions of each sub-problem are a good initial guess of the optimum ...

Global competitiveness has forced manufacturing firm, as an internal constituents, to work closer with their suppliers and customers in order to produce highly innovative product in shorter time interval. However as the business trends in manufacturing industry have evolved, centralized integration has become obsolete and no longer be efficient. Concurrent engineering methodology allows manufacturing firms to adopt a new collaboration approach called virtual integration. With the aid of computer-mediated communication, virtual integration is believed to be a promising solution to NPD collaboration issues. Therefore, this conceptual paper is aimed to seek for a new approach to engender product innovation which ...


Performance Evaluation Of Organic Emulsion Liquid Membrane On Phenol Removal, Yee Sern Ng, Jayakumar Subramaniam, Mohd Ali Hashim 2009 University of Malaya

Performance Evaluation Of Organic Emulsion Liquid Membrane On Phenol Removal, Yee Sern Ng, Jayakumar Subramaniam, Mohd Ali Hashim

Ng Yee-Sern

The percentage removal of phenol from aqueous solution by emulsion liquid membrane and emulsion leakage was investigated experimentally for various parameters such as membrane:internal phase ratio, membrane:external phase ratio, emulsification speed, emulsification time, carrier concentration, surfactant concentration and internal agent concentration. These parameters strongly influence the percentage removal of phenol and emulsion leakage. Under optimum membrane properties, the percentage removal of phenol was as high as 98.33%, with emulsion leakage of 1.25%. It was also found that the necessity of carrier for enhancing phenol removal was strongly dependent on the internal agent concentration.


Special Issue: Crop Water Use Efficiency At Multiple Scales, Timothy Green 2009 USDA Agricultural Research Service

Special Issue: Crop Water Use Efficiency At Multiple Scales, Timothy Green

Timothy R. Green

Food security is an issue of global concern, which is tightly linked with water supply issues as regional demands for water are dominated by agricultural water use. This special issue of Agricultural Water Management focuses on crop–water use in China, especially in the North China Plain (NCP) and Loess Plateau and surrounding areas, where intensive agriculture (e.g., wheat–maize double cropping) with limited water is practiced to meet the large demand for grains. Such intensive agriculture raises concerns for agricultural sustainability due to limited water supply and effects on water quality, which may be aggravated by projected climate ...

We examine the evolution (‘healing’) of the interface between two polymer films at various temperatures below the glass transition temperature, Tg. Specifically, neutron reflectometry is used to study the relaxation of the interface between both unentangled and entangled deuterated polystyrene (d-PS) and hydrogenated polystyrene (h-PS) films in the glass state where these bilayer films are supported on silicon substrates. We find that the initially sharp interface between the glassy polymer layers broadens with time (t), but the average interfacial thickness Δσ(t) between these layers then saturates after long time to a thickness (ξp) in a range between 1 nm ...
