Enhancing Security At Baxter Arena, Jennifer Davis

Theses/Capstones/Creative Projects

The purpose of this report is to detail two options proposed for enhancing security at Baxter Arena. Both options are focused on metal detection. In this report we will look at the benefits and negatives of metal detection, both handheld and stationery, and how it can be used in enhancing building security.

Operation Optimization And Water Quality Simulation Of Potable Water Distribution System, Xiongfei Xie

USF Tampa Graduate Theses and Dissertations

A potable water distribution system (WDS) consists of pipes, pumps, valves, storage tanks, control and supporting components. Traditionally, it has two basic functions. First, provides end users with potable water at sufficient pressures and good water quality. Second, provides sufficient pressure and flow for fire fighting. Currently, potable water is still the least expensive material for fire fighting. To accomplish these two goals, water utilities have to consider the integrity and security of the water network. As a result, this research selected three research topics that are closely related to the daily operation of water utilities and water quality simulation. …

A Multi-Criteria Methodology For Measuring The Resilience Of Transportation Assets And Prioritizing Security Investments, Michelle S. Dojutrek, Samuel Labi, J Eric Dietz

International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference

Transportation project prioritization uses performance measures that are related to the transportation asset, its operations, and its environment. However, in the state of practice, evaluation does not consider directly the likelihood of natural or man-made threats, the infrastructure resilience, or the consequences of the infrastructure damage in the event that the threat occurs. Thus, during the prioritization of investments, assets of low security do not receive the due attention they deserve. In defining security as the lack of risk of damage from threats due to inherent structure or functional resilience, this paper is based on the premise that the inclusion …

Methodologies For The Analysis Of Checked Baggage Inspection Systems, Nela Blejcharova

Open Access Theses & Dissertations

To enhance the security of the aviation system it is necessary to have a Checked Baggage Inspection System (CBIS) that is effective (that is, the highest possible detection probability or minimum false clear probability) yet efficient (that is, minimize the false alarm probability that causes inconvenience to passengers).

The first objective of this thesis is to review passenger, carry-on and checked baggage inspection procedures at airports

The second objective of this thesis is to develop a methodology using the optimization approach to set the optimal values of the sensitivity of the screening devices to minimize the total cost of inspecting …

Pattern Recognized Surveillance System, Purdue Ect Team

ECT Fact Sheets

The ultimate objective is to create a complete-decision maker which allows us to detect the new state and initiate appropriate actions taking and analyzing all historical and current information based upon adaptive reasoning. Computers have the ability to extract information from multiple sources and identify and track patterns of activity that are inconsistent with "normal" operations.

Emerging Video Surveillance And Monitoring Technologies, Purdue Ect Team

ECT Fact Sheets

The traditional video surveillance applications have some limitations; 1) one unit per one person in one place, 2) the limited area for surveillance due to the location of cameras 3) increasing operating cost, 4) hard reductions in theft and claim rates over the long term. Recently, video technology has grown by leaps and bounds throughout the last few years due to the steep development of Information Technology (IT). The newest video surveillance technologies seem to be taking two aspects: 1) Digital Video Surveillance (DVS) of a turn toward digital video servers using Internet access, and 2) Multi-modal User Interface (MUI).

Air Ventilation Protection System For Building Security, Purdue Ect Team

ECT Fact Sheets

The new technology to solve the limitation of conventional Collective protection equipment (CPE) system has been developed as "Combined ESP/ESF/PCO and microfibrous media CPE application". This concept of this new technology is the combination of the both systems; 1) Microfibrous Material Technology, and 2) Photocataytic Oxidation Technology.

New Access Control Technologies: Biometric Identification, Purdue Ect Team

ECT Fact Sheets

Biometrics are computerized methods of recognizing people based on physical or behavioral characteristics. The main biometric technologies include face recognition, fingerprint, hand geometry, iris, palm prints, signature and voice. Biometric technologies can work in two modes – authentication (one-to-one matching) and identification (one-to-many) matching. However, only three biometrics are capable of the latter – face, finger and iris.

Acoustic Wave Sensors, Purdue Ect Team

ECT Fact Sheets

Modern office buildings are generally considered safe and healthful working environments. However, energy conservation measures have minimized the infiltration of outside air and contributed to the buildup of indoor air contaminants. Three products manufactured by Microsensor Systems Inc. are introduced: HAZMATCAD, CW Sentry Plus, MiniCAD MKII.

Infrared Gas Sensor, Purdue Ect Team

ECT Fact Sheets

In recent years, the rapid development of monitoring and detecting technology of indoor air quality have been observed. We have seen the two major streams of detection technology introduced so far: Acoustic wave sensor and Infrared gas sensor. The use of a gas monitoring system in the case of that dangerous levels of gases are detected, can help to prevent an explosion or can help to prevent worker injury or exposure to toxic gases.
