Capacity Reduction And Fire Load Factors For Lrfd Of Steel Members Exposed To Fire, Shahid Iqbal, Ronald S. Harichandran
Capacity Reduction And Fire Load Factors For Lrfd Of Steel Members Exposed To Fire, Shahid Iqbal, Ronald S. Harichandran
Civil Engineering Faculty Publications
A general reliability-based methodology is proposed for developing capacity reduction and fire load factors for design of steel members exposed to fire. The effect of active fire protection systems (e.g., sprinklers, smoke and heat detectors, fire brigade, etc.) in reducing the probability of occurrence of a severe fire is included. The design parameters that significantly affect the fire design of steel members are chosen as random variables. Raw experimental data published in the literature was analyzed to obtain the statistics of parameters for which no statistical information was available in the literature. Model errors associated with the thermal analysis models …
Iphone 3gs Forensics: Logical Analysis Using Apple Itunes Backup Utility, Mona Bader, Ibrahim Baggili
Iphone 3gs Forensics: Logical Analysis Using Apple Itunes Backup Utility, Mona Bader, Ibrahim Baggili
Electrical & Computer Engineering and Computer Science Faculty Publications
The iPhone mobile is used worldwide due to its enhanced computing capabilities, increased storage capacity as well as its attractive touch interface. These characteristics made the iPhone a popular smart phone device. The increased use of the iPhone lead it to become a potential source of digital evidence in criminal investigations. Therefore, iPhone forensics turned into an essential practice for forensic and security practitioners today. This research aimed at investigating and examining the logical backup acquisition of the iPhone 3GS mobile device using the Apple iTunes backup utility. It was found that significant data of forensic value such as e-mail …
Generating System Requirements For A Mobile Digital Evidence Collection System: A Preliminary Step Towards Enhancing The Forensic Collection Of Digital Devices, Ibrahim Baggili
Electrical & Computer Engineering and Computer Science Faculty Publications
Collecting digital devices in a forensically sound manner is becoming more critical since 80% of all cases have some sort of digital evidence involved in them (Rogers, 2006, p. 1) .The process of documenting and tagging digital devices is cumbersome and involves details that might not apply to other types of evidence, since each evidence item has unique physical characteristics (Hesitis & Wilbon, 2005, p. 17). The process becomes less manageable when a large number of digital devices are seized. This paper examines the information and issues investigators should be aware of when collecting digital devices at crime scenes. Furthermore, …
Computational Models Of Thermal Cycling In Chemical Systems, Carl Barratt, Dante Lepore, Matthew Cherubini, Pauline Schwartz
Computational Models Of Thermal Cycling In Chemical Systems, Carl Barratt, Dante Lepore, Matthew Cherubini, Pauline Schwartz
Mechanical and Industrial Engineering Faculty Publications
Computational models of chemical systems provide clues to counterintuitive interactions and insights for new applications. We have been investigating models of chemical reaction systems under forced, thermal cycling conditions and have found that some hypothetical processes generate higher yields under thermal cycling than under single, fixed temperature conditions. A simple kinetic model of an actual process, the two-temperature polymerase chain reaction that replicates DNA, is used to simulate the important features of a chemical system operating under thermal cycling. This model provides insights into the design of other chemical systems that may have important applications in chemistry, biochemistry and chemical …
