Applications Of Combinatorial Designs In Key Pre-Distribution In Sensor Networks., Dibyendu Chakrabarti Dr.
Doctoral Theses
Key pre-distribution is an important area of research in Distributed Sensor Networks (DSN). Some improved techniques over the existing schemes (employing combinatorial designs) have been proposed in this thesis and detailed mathematical analysis of the schemes has been presented. At first, combinatorial design followed by randomized merging strategy is applied to key pre-distribution in sensor nodes. Our main target is to get more than one pair of common keys between any pair of nodes to provide a robust network in terms of security under adversarial conditions where some nodes may get compromised. A transversal design is used to construct a …

Algorithms For Some Geometric Facility Location And Path Planning Problems., Sasanka Roy Dr.
Doctoral Theses
The facility location problem is a resource allocation problem that mainly deals with adequate placement of various types of facilities to serve a distributed set of demands satisfying the nature of interactions between the demands and facilities and optimizing the cost of placing/maintaining the facilities and the quality of services.The facility location problem is well-studied in the Operations Research literature and recently has received a lot of attention in the Computer Science community. For a company, the facility location problem provides more strategic decisions than just giving importance to locate the lowest cost space for storing its products. While identifying …
An Investigation Of Communication Patterns And Strategies Between International Teaching Assistants And Undergraduate Students In University-Level Science Labs, Barbara Elas Gourlay
An Investigation Of Communication Patterns And Strategies Between International Teaching Assistants And Undergraduate Students In University-Level Science Labs, Barbara Elas Gourlay
Master's Theses, Dissertations, Graduate Research and Major Papers Overview
Investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. Qualitative and quantitative data from observations and interviews with study participants guide the analysis of laboratory interactions, which examines patterns of conversational listening. Results reveal that successful communication depends on teaching assistant listening comprehension skills and on the coordination of verbal and visual (gestural and physical resources) sources of information.
An Examination Into How Group Performance Is Influenced By Various Communication Channels, Jason C. Norgaard
An Examination Into How Group Performance Is Influenced By Various Communication Channels, Jason C. Norgaard
Theses and Dissertations
This purpose of this research was to look at the how group performance is influenced by various communication channels. Specifically, this research sought to determine what communication factors are affected when groups are forced to use different communications channels. The three communications channels tested were face-to-face communications, audio conferencing, and computer-mediated communications through an Internet chat program. Each channel was measured on accuracy, efficiency, and total number of ideas generated. The research found that the groups using computer-mediated communications had a difficult time completing the exercises in the allotted time. Additionally, the computer-mediated produced significantly fewer total words and total …
