| Abstract | When utilizing metal detectors at a large venue such as a sports stadium, there are the competing objectives of accuracy of the patron screening and the speed of throughput. This research, carried out in collaboration with the security staff at MetLife Stadium in New Jersey as well as other stadiums, analyzed two patron screening methods: handheld metal detectors (“wands”) and walk-through metal detectors (“walk-throughs”). An initial experimental design was created to understand the effectiveness of wanding. This design was used with MetLife Stadium security during three training sessions. The data collected was used to understand (a) if the prohibited item was found and (b) in how many attempts. Various prohibited as well as allowable metal items were hidden at random in various locations on the body of individuals, who were then scored based on the importance weight of the item (guns were given more weight than keys for example). Trainees were then assigned a performance score based on speed and accuracy and were tested until they reached a minimum required score. Building on this initial experiment, a second more formal experiment was created to help MetLife Stadium staff understand how walk-throughs would perform outdoors at different security settings. This experiment focused less on training security staff and more on understanding the performance of walk-throughs in real situations (as opposed to idealized lab situations). This experiment was created to understand the walk-through performance at each setting in the outdoor environment; e.g., does a walk-through catch each of the pre-specified prohibited items, and is this consistent across machines on the same setting? Because of the number of factors to be considered (type of item, location, orientation, walk-through setting, etc.), designing the experiment required a sophisticated approach called Combinatorial Experimental Design. The experiment was part of two DHS-supported projects on best practices for stadium security. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
