Natural Language Processing And E-Government: Crime Information Extraction From Heterogeneous Data Sources, Chih Hao Ku '12, Alicia Iriberri '06, Gondy Leroy
CGU Faculty Publications and Research
Much information that could help solve and prevent crimes is never gathered because the reporting methods available to citizens and law enforcement personnel are not optimal. Detectives do not have sufficient time to interview crime victims and witnesses. Moreover, many victims and witnesses are too scared or embarrassed to report incidents. We are developing an interviewing system that will help collect such information. We report here on one component, the crime information extraction module, which uses natural language processing to extract crime information from police reports, newspaper articles, and victims’ and witnesses’ crime narratives. We tested our approach with two …

Topological And Categorical Properties Of Binary Trees, Homeira Pajoohesh
Topological And Categorical Properties Of Binary Trees, Homeira Pajoohesh
Publications and Research
Binary trees are very useful tools in computer science for estimating the running time of so-called comparison based algorithms, algorithms in which every action is ultimately based on a prior comparison between two elements. For two given algorithms A and B where the decision tree of A is more balanced than that of B, it is known that the average and worst case times of A will be better than those of B, i.e., ₸A(n) ≤₸B(n) and TWA (n)≤TWB (n). Thus the most balanced and the most imbalanced binary trees play a main role. Here we consider them as semilattices …

Anatomy Of An Arabetic Type Design, Saad D. Abulhab
Anatomy Of An Arabetic Type Design, Saad D. Abulhab
Publications and Research
Arabetic type design, like type design in general, should not be limited by rigid rules, other than those advocating open choice and user options. But as with all design fields, highlighting certain principles and guidelines is crucial to realizing a successful project. In an Arabetic font design environment, such guidelines and principles should reveal deeper understanding of various scripts visual and behavioral defining characteristics rather than mere traditional calligraphic and handwriting norms. A main goal of this study is to emphasize that designing Arabetic fonts is much easier than it is portrayed, and designers of all backgrounds should be more …

Regis University Student Publications (comprehensive collection)
With the push to streamline medical records and the use of electronic medical records system technology on the rise, successful implementation is important. The push is due in part for the need to reduce unnecessary paperwork, increase reimbursement, increase quality of medical records and increase overall quality of care. Factors to consider are the effects of implementation on quality of care, quality of medical records, physician and staff perceptions, working conditions, patient satisfaction, cost and barriers. Implementation may have a positive, negative or neutral effect on these factors making the need to review literature and report outcomes significant.

Detecting Curved Objects Against Cluttered Backgrounds, Jan Prokaj
Detecting Curved Objects Against Cluttered Backgrounds, Jan Prokaj
Electronic Theses and Dissertations
Detecting curved objects against cluttered backgrounds is a hard problem in computer vision. We present new low-level and mid-level features to function in these environments. The low-level features are fast to compute, because they employ an integral image approach, which makes them especially useful in real-time applications. The mid-level features are built from low-level features, and are optimized for curved object detection. The usefulness of these features is tested by designing an object detection algorithm using these features. Object detection is accomplished by transforming the mid-level features into weak classifiers, which then produce a strong classifier using AdaBoost. The resulting …
Mitigating Dos Attacks Against Broadcast Authentication In Wireless Sensor Networks, Peng Ning, An Liu, Wenliang Du
Mitigating Dos Attacks Against Broadcast Authentication In Wireless Sensor Networks, Peng Ning, An Liu, Wenliang Du
Electrical Engineering and Computer Science - All Scholarship
Broadcast authentication is a critical security service in wireless sensor networks. There are two general approaches for broadcast authentication in wireless sensor networks: digital signatures and µTESLA-based techniques. However, both signature-based and µTESLA-based broadcast authentication are vulnerable to Denial of Services (DoS) attacks: An attacker can inject bogus broadcast packets to force sensor nodes to perform expensive signature verifications (in case of signature-based broadcast authentication) or packet forwarding (in case of µTESLA-based broadcast authentication), thus exhausting their limited battery power. This paper presents an efficient mechanism called message specific puzzle to mitigate such DoS attacks. In addition to signature-based or …
Increasing Localization Precision In Sensor Networks With Mobile Beacons - A Genetic Path Planning Approach, Awais Iqbal
Increasing Localization Precision In Sensor Networks With Mobile Beacons - A Genetic Path Planning Approach, Awais Iqbal
Computer Science and Engineering Theses - Archive
This work describes a genetic algorithm based approach to approximate an optimal path for a mobile beacon node in a grid of stationary wireless sensors. As the beacon moves over the field of sensors it broadcasts its location. Sensors that are currently in the proximity of the beacon will receive this communication and can then use several of these messages to compute estimates on their locations. An optimal path is defined as a path that will result in the highest overall precision of location estimates among sensors given a maximum path length for the beacon. We assume that sensors are …
Multi-View Approaches To Tracking, 3d Reconstruction And Object Class Detection, Saad Khan
Multi-View Approaches To Tracking, 3d Reconstruction And Object Class Detection, Saad Khan
Electronic Theses and Dissertations
Multi-camera systems are becoming ubiquitous and have found application in a variety of domains including surveillance, immersive visualization, sports entertainment and movie special effects amongst others. From a computer vision perspective, the challenging task is how to most efficiently fuse information from multiple views in the absence of detailed calibration information and a minimum of human intervention. This thesis presents a new approach to fuse foreground likelihood information from multiple views onto a reference view without explicit processing in 3D space, thereby circumventing the need for complete calibration. Our approach uses a homographic occupancy constraint (HOC), which states that if …
Improving Branch Prediction Accuracy Via Effective Source Information And Prediction Algorithms, Hongliang Gao
Improving Branch Prediction Accuracy Via Effective Source Information And Prediction Algorithms, Hongliang Gao
Electronic Theses and Dissertations
Modern superscalar processors rely on branch predictors to sustain a high instruction fetch throughput. Given the trend of deep pipelines and large instruction windows, a branch misprediction will incur a large performance penalty and result in a significant amount of energy wasted by the instructions along wrong paths. With their critical role in high performance processors, there has been extensive research on branch predictors to improve the prediction accuracy. Conceptually a dynamic branch prediction scheme includes three major components: a source, an information processor, and a predictor. Traditional works mainly focus on the algorithm for the predictor. In this dissertation, …
