A study of the technology leadership of Texas high school principals.
… Technology Standards for Administrators (NETS*A). In addition, this study compares technology leadership among principals who have attended the Technology Leadership Academy with those who have not attended this training. The two questions that guided this study are: (1) What are the …

Enhancing Education Through Technology: Prinicpal Leadership For Technology Integration In Schools
… Technology Standards for Administrators (NETS-A; International Society for Technology in Education, 2002) are being implemented in schools. The purpose of this study is to analyze the extent to which Michigan elementary principals employ behaviors that support their role as effective …

K-12 Principals' Perceptions of Their Technology Leadership Preparedness
… to enhance teaching and learning. The 2009 NETS-A standards were used to define the dimensions of leader preparedness for a technology-rich environment. The research design used a quasi-experimental quantitative study to identify leaders' perceptions of technology leadership preparedness and …

Conditional Preference Networks: Learning and Optimization
… is that of Conditional Preference Networks (CP-nets). A CP-net de nes a partial order over the set of outcomes or alternatives by providing a concise set of small preference statements. Since their introduction, CP-nets have been intensively studied and applied in various problems involving …

Summarizing Conditional Preference Networks
… model, Con- ditional Preference Networks (CP-nets). A CP-net is a graphical model that captures the preferences of an individual using a directed graph, with vertices representing attributes and edges representing dependency relations between attributes. Information about the preferential …

Generalised Markovian analysis of timed transition systems
… including Generalised Stochastic Petri nets, queueing networks and Queueing Petri nets. A system modelled with one of these formalisms may be mapped onto a Markov chain through a process known as state space generation. The Markov chain thus generated can then be solved for its …

The Mzingazi gauging weir and its effects on the fish and macrocrustacean communities of Lake Mzingazi
… 2007 to July 2008, using funnel traps, dip nets and a small seine net. In order to monitor the effect of the fishway on the lake fish community, seasonal sampling in the lake was conducted for a period of two years, from August 2007 to June 2009, using seine and gill nets. A total of 3 288 …

Disjunctive normal formula based supervisory control policy for general Petri nets
… our attention to a class of general Petri nets (PN) structures, where the existence of an LESP for an instance initialized at a marking, implies the existence of an LESP when the same instance is initialized with a larger initial marking. We show that the minimally restrictive LESP for an …

On the convexity of right-closed sets and its application to liveness enforcement in Petri Nets
… Policies (LESPs) for a large family of Petri Nets (PNs). For any PN structure N from this family, the set of initial markings, (N), for which there is a LESP, is right-closed. A LESP determines the transitions of a PN that are to be permitted to re at any marking in such a manner that, …

On the decidability of problems in liveness of controlled Discrete Event Systems modeled by Petri Nets
… a modeling paradigm of DESs known as Petri Nets, which have applications in modeling concurrent systems, software design, manufacturing systems, etc. Petri Net (PN) models are inherently monotonic in the sense that if a transition (which loosely represents an event of the DES) can fire from …

State estimation and sensor selection in discrete event systems modeled by Petri nets
… across places in the system). Sensors in Petri nets come in two major types: place sensors (i.e., sensors that indicate the number of resources in a particular place, e.g., vision sensors) and transition sensors (i.e., sensors that can detect whether a transition in a given subset of transitions …
