The application and performance of a generic task routine decision making algorithm to recipe selection in meal planning

A nutritional meal planning system was implemented to test the effectiveness of a previously developed routine decision making algorithm. The combinatorics involved in ordering recipes in all possible combinations to produce variability in a meal plan and provide sufficient nutrition is conceptually intensive. Meal planning involves selection of food to eat to fulfill a person\u27s nutritional and personal preferences. This thesis demonstrates meal planning as a decision making problem and demonstrates the utility of the routine decision making algorithm by solving this problem. Generic Tasks, identified through artificial intelligence research, provides the basis for this algorithm. It uses user preferences and to select recipes from a database of possible recipes and generate meal plans for the user

Distributed Dynamic Hierarchical Task Assignment for Human-Robot Teams

This work implements a joint task architecture for human-robot collaborative task execution using a hierarchical task planner. This architecture allowed humans and robots to work together as teammates in the same environment while following several task constraints. These constraints are 1) sequential order, 2) non-sequential, and 3) alternative execution constraints. Both the robot and the human are aware of each other's current state and allocate their next task based on the task tree. On-table tasks, such as setting up a tea table or playing a color sequence matching game, validate the task architecture. The robot will have an updated task representation of its human teammate's task. Using this knowledge, it is also able to continuously detect the human teammate's intention towards each sub-task and coordinate it with the teammate. While performing a joint task, there can be situations in which tasks overlap or do not overlap. We designed a dialogue-based conversation between humans and robots to resolve conflict in the case of overlapping tasks.Evaluating the human-robot task architecture is the next concern after validating the task architecture. Trust and trustworthiness are some of the most critical metrics to explore. A study was conducted between humans and robots to create a homophily situation. Homophily means when a person feels biased towards another person because of having similarities in social ways. We conducted this study to determine whether humans can form a homophilic relationship with robots and whether there is a connection between homophily and trust. We found a correlation between homophily and trust in human-robot interactions.Furthermore, we designed a pipeline by which the robot learns a task by observing the human teammate's hand movement while conversing. The robot then constructs the tree by itself using a GA learning framework. Thus removing the need for manual specification by a programmer each time to revise or update the task tree which makes the architecture more flexible, realistic, efficient, and dynamic. Additionally, our architecture allows the robot to comprehend the context of a situation by conversing with a human teammate and observing the surroundings. The robot can find a link between the context of the situation and the surrounding objects by using the ontology approach and can perform the desired task accordingly. Therefore, we proposed a human-robot distributed joint task management architecture that addresses design, improvement, and evaluation under multiple constraints

6th Annual Focus on Creative Inquiry Poster Forum Program

The poster forum today displays a few of the more than 400 projects initiated by Clemson University Creative Inquiry teams. What is Creative Inquiry? It is small-group learning for all students. It is the imaginative combination of engaged learning and undergraduate research. Ultimately, it is the creation of an Ah-ha! Moment - and it is unique to Clemson University. Creative Inquiry establishes small teams of undergraduate students that work with faculty mentors to take on problems that spring from their own curiosity, from a professor\u27s challenge, or from the pressing needs of the world around them. Students take ownership of their projects. They ask questions, they take risks, and they get answers

Priming as a Means of Increasing Spontaneous Verbal Language in Children with Autism Spectrum Disorder

ABSTRACT THE EFFECTS OF PRIMING ON SPONTANEOUS VERBAL LANGUAGE IN CHILDREN WITH AUTISM SPECTRUM DISORDERS by Michelle L. Ivey A multi-element design was used to investigate the effect of priming on spontaneous verbal communication in children with Autism Spectrum Disorders (ASD). Three children with ASD engaged in 20-minute thematic activity sessions (ACT) with the investigator. Prior to the ACTs, they met with another trained researcher for 10-minute presessions. Half of the presessions incorporated the conventions of priming with materials to be used in the upcoming ACT (i.e., related presessions; RP). During the other half of the presessions, participants were not primed for the upcoming ACT (i.e., unrelated presesessions; UP). The researcher conducted presessions so the investigator was blind to the condition. Procedural fidelity checks of the presessions, based on a checklist of the critical components of priming, revealed 100% adherence to procedures. Participants’ utterances during ACT were recorded, transcribed, and coded based on functionality. The dependent variables were spontaneous comments, requests, topic initiations, social information seeking, and total. Once the criterion of a 30% increase from the mean of the first 3 UP was achieved for three consecutive sessions, priming was withdrawn and then reinstated to demonstrate a functional relation. Additionally, Cohen\u27s d was calculated to determine effect size for the intervention. Reliability was assessed for transcription and coding. There were fewer than 10 word disagreements on any transcript, which did not affect coding. A line by line comparison of the coding across the dependent variables yielded an average reliability of 85%. Visual inspection of the data and statistical analysis revealed that two of the three participants reached criterion for spontaneous comments (Cohen\u27s d = .32 and .95), one reached criterion for total utterances (Cohen\u27s d = 2.99), the other achieved the goal during the reinstatement following the withdrawal (Cohen’s d = 1.00). None increased requesting. Topic initiation and social information seeking did not occur with sufficient frequency for meaningful analyses. Similar to most interventions with individuals with ASD, priming was effective for increasing spontaneous verbal comments for some but not all of the participants. Priming was highly effective for two of the participants. This ground-breaking study creates momentum for further investigation and examination of the variables that affect benefit

RFID Technology in Intelligent Tracking Systems in Construction Waste Logistics Using Optimisation Techniques

Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system’s utilization
