Students with Special Needs and Their Interaction with Peers during Play
This qualitative study was designed to document the characteristics of peer interaction in students with special needs . The qualitative nature of this study was most beneficial because while analyzing data from the interviews and observations, I had obtained thick, rich descriptive data on the behaviors of a student with special needs during play.
An observational study took place in an inclusive classroom with three students with special needs, and the typically developing peers with whom they interacted with during play. These observations allowed for the collection and interpretation of the ways in which students with special needs interact with peers during play. In addition to observation, I conducted a focus group interview. This interview took place with specific professionals within the elementary school. The collection and interpretation of this interview provided differing perspectives on my research questions
Inflatable O-ring seal would ease closing of hatch cover plate
Inflatable O-ring seal provides positive sealing means that does not require the manual exertion of a large compressive force during opening or closing of a rotary-type hatch cover plate. The O-ring is deflated during opening and closing and inflated after closure by a gas pressure source
Computational Processes and Incompleteness
We introduce a formal definition of Wolfram's notion of computational process
based on cellular automata, a physics-like model of computation. There is a
natural classification of these processes into decidable, intermediate and
complete. It is shown that in the context of standard finite injury priority
arguments one cannot establish the existence of an intermediate computational
process
The Pagoda Sequence: a Ramble through Linear Complexity, Number Walls, D0L Sequences, Finite State Automata, and Aperiodic Tilings
We review the concept of the number wall as an alternative to the traditional
linear complexity profile (LCP), and sketch the relationship to other topics
such as linear feedback shift-register (LFSR) and context-free Lindenmayer
(D0L) sequences. A remarkable ternary analogue of the Thue-Morse sequence is
introduced having deficiency 2 modulo 3, and this property verified via the
re-interpretation of the number wall as an aperiodic plane tiling
A Concrete View of Rule 110 Computation
Rule 110 is a cellular automaton that performs repeated simultaneous updates
of an infinite row of binary values. The values are updated in the following
way: 0s are changed to 1s at all positions where the value to the right is a 1,
while 1s are changed to 0s at all positions where the values to the left and
right are both 1. Though trivial to define, the behavior exhibited by Rule 110
is surprisingly intricate, and in (Cook, 2004) we showed that it is capable of
emulating the activity of a Turing machine by encoding the Turing machine and
its tape into a repeating left pattern, a central pattern, and a repeating
right pattern, which Rule 110 then acts on. In this paper we provide an
explicit compiler for converting a Turing machine into a Rule 110 initial
state, and we present a general approach for proving that such constructions
will work as intended. The simulation was originally assumed to require
exponential time, but surprising results of Neary and Woods (2006) have shown
that in fact, only polynomial time is required. We use the methods of Neary and
Woods to exhibit a direct simulation of a Turing machine by a tag system in
polynomial time
On the boundaries of solvability and unsolvability in tag systems. Theoretical and Experimental Results
Several older and more recent results on the boundaries of solvability and
unsolvability in tag systems are surveyed. Emphasis will be put on the
significance of computer experiments in research on very small tag systems
Multi-Head Finite Automata: Characterizations, Concepts and Open Problems
Multi-head finite automata were introduced in (Rabin, 1964) and (Rosenberg,
1966). Since that time, a vast literature on computational and descriptional
complexity issues on multi-head finite automata documenting the importance of
these devices has been developed. Although multi-head finite automata are a
simple concept, their computational behavior can be already very complex and
leads to undecidable or even non-semi-decidable problems on these devices such
as, for example, emptiness, finiteness, universality, equivalence, etc. These
strong negative results trigger the study of subclasses and alternative
characterizations of multi-head finite automata for a better understanding of
the nature of non-recursive trade-offs and, thus, the borderline between
decidable and undecidable problems. In the present paper, we tour a fragment of
this literature
Enhancing teaching and learning through dialogue: a student and staff partnership model
This paper explores a model for developing student and staff partnerships to enhance the quality of teaching and learning and situates the model in literature on student engagement. The model enables staff and students to step outside their normal roles and the traditional student-teacher relationship into a less pre-defined mode of interaction and liminal space where conversations about teaching and learning can take place. At the most transformative, this model enables academic staff to get a sense of learner perspectives and to view students as partners and collaborators while students develop insights into the perspectives of staff. The authors argue that the model represents an innovative approach to engaging students in a meaningful way in enhancing teaching and learning and has the potential to reframe the student-teacher relationship into a more collaborative one that goes beyond listening to students
Playing With Population Protocols
Population protocols have been introduced as a model of sensor networks
consisting of very limited mobile agents with no control over their own
movement: A collection of anonymous agents, modeled by finite automata,
interact in pairs according to some rules.
Predicates on the initial configurations that can be computed by such
protocols have been characterized under several hypotheses.
We discuss here whether and when the rules of interactions between agents can
be seen as a game from game theory. We do so by discussing several basic
protocols
