We present a methodology to construct optimal visibility graphs from vector and raster terrain data based on the integration of Geographic Information systems, computational geometry, and integer linear programming. In an emergency situation, the ability to observe an environment, completely or partially, is crucial when searching an area for survivors, missing persons, intruders or anomalies. We first analyze inter-visibility using computational geometry and GIS functions. Then, we optimize the visibility graphs by choosing vertices in a way to either maximize coverage with a given number of watchers or to minimize the number of watchers needed for full coverage.

In this paper, we propose SocioPhone, a novel initiative to build a mobile platform for face-to-face interaction monitoring. Face-to-face interaction, especially conversation, is a fundamental part of everyday life. Interaction-aware applications aimed at facilitating group conversations have been proposed, but have not proliferated yet. Useful contexts to capture and support face-to-face interactions need to be explored more deeply. More important, recognizing delicate conversational contexts with commodity mobile devices requires solving a number of technical challenges. As a first step to address such challenges, we identify useful meta-linguistic contexts of conversation, such as turn-takings, prosodic features, a dominant participant, and pace. These serve as cornerstones for building a variety of interaction-aware applications. SocioPhone abstracts such useful meta-linguistic contexts as a set of intuitive APIs. Its runtime efficiently monitors registered contexts during in-progress conversations and notifies applications on-the-fly. Importantly, we have noticed that online turn monitoring is the basic building block for extracting diverse meta-linguistic contexts, and have devised a novel volume-topography-based method. We show the usefulness of SocioPhone with several interesting applications: SocioTherapist, SocioDigest, and Tug-of-War. Also, we show that our turnmonitoring technique is highly accurate and energy-efficient under diverse real-life situations. Copyright 2013 ACM.

Designing cyber-physical systems (CPS) is challenging due to the tight interactions between software, network/platform, and physical components. A co-simulation method is valuable to enable early system evaluation. In this paper, a co-simulation framework that considers interacting CPS components for design of time-triggered (TT) CPS is proposed. Virtual prototyping of CPS is the core of the proposed framework. A network/platform model in SystemC forms the backbone of the virtual prototyping, which bridges control software and physical environment. The network/platform model consists of processing elements abstracted by realtime operating systems, communication systems, sensors, and actuators. The framework is also integrated with a model-based design tool to enable rapid prototyping. The framework is validated by comparing simulation results with the results from a hardware-in-the-loop automotive simulator.

Service-Oriented Programming (SOP) has emerged as a new programming paradigm that allows the wrapping of existing software as web services, thus permitting the development of new software applications by using existing web services as building blocks. SOP has attracted great attention from industry as it dramatically increases software reuse. Despite the growing demand for an SOP-trained workforce, SOP has not been adequately covered in coursework for undergraduate students in computer science (CS) and software engineering (SE). This project addresses this curricular shortcoming via the design and creation of SOP materials for undergraduate CS and SE. The concept of course modules-self-contained units of instruction that can be incorporated into several existing courses-is used to make these materials accessible at multiple educational institutions. This paper describes an exemplification and visualization framework that supports the teaching of SOP, along with three course modules that can be folded into typical courses currently offered to CS or SE undergraduates.

The McCracken et al. working group paper is often cited for the proposition that students can't program. In that study, students from four different institutions were each assigned to implement one of three versions of a calculator. More than half of the students failed to produce a program that compiled and executed in the time assigned. Lost in this discussion, however, is the fact that the original paper had the goal of evaluating its instrument, as well as the students. We examine and adjust their instrument, and present the results of the revised study. With a modified instrument, we have obtained significantly improved results. Copyright © 2013 ACM.

We describe a robot capable of composing and playing traditional Basque impromptu verses -bertsoak. The system, called Bertsobot, is able to construct improvised verses according to given constraints on rhyme and meter, and to perform it in public. Towards this end, several tools and applications have been developed and integrated in Bertsobot, including: speech-based communication system, text applications for verse generation, and robot behaviours to interact with the environment in a public performance. We describe the tools and processes behind our approach, present some early experimental results and illustrative verses, and finally, remark the conclusions and future steps.

Automated Essay Grading (AEG) is defined as a computer technology that evaluates and scores written prose. A number of AEG systems have been developed since the 1960s and in most of them, an ad-hoc or generalized approach is used to grade spelling even though it is an important element of an essay-scoring rubric. Existing approaches do not therefore give an accurate representation or measure of spelling in essays. According to the rubric-based scoring method used in the National Assessment Program "Literacy and Numeracy (NAPLAN) in Australia, spelling is marked in three steps" first, by identifying the correct and incorrect words in the essay;second, by categorizing each word based on the difficulty level into one of four classes: Simple, Common, Difficult or Challenging, and counting the number of correct and incorrect words in each category;finally, by using the pre-defined NAPLAN rubric scale to assign the mark. Only a small number of existing AEG systems can be used for rubric-based scoring, and none can be used to grade spelling according to the NAPLAN rubric. In this paper, we address this shortcoming in the existing literature and present an innovative approach to automatically mark spelling using rubric based scoring. We develop two algorithms based on the rules and heuristics of the English language to formulize the rubric for spelling and then implement these algorithms in Java language and perform a series of evaluations of our system using an essay dataset. Our results are very promising, even though it is the first system of this kind.

Teaching introductory programming to IS students: The impact of teaching approaches on learning performance

Journal of Information systems Education 2013年第2期24卷 147-155页

Introductory programming courses are typically required for undergraduate students majoring in Information systems. Instructors use different approaches to teaching this course: some lecturing and assigning programming exercises, others only assigning programming exercises without lectures. This research compares the effects of these two teaching approaches on learning performance by collecting data from two sections of an introductory programming course in an urban public university. One section used lectures and assignments while the other used assignments only. Data analysis included tests within each dataset, tests across the two datasets, and tests of a simple model over the combined dataset. Results indicated that both approaches are effective, but the exercises-only approach is more effective than lectures combined with exercises. Further analysis indicated that students' current programming skills, prior programming experience, and grade expectations are significant antecedents of learning performance in the course. Results support the conclusion suggesting that when teaching introductory programming courses, instructors may want to consider choosing the student-centered active learning over the traditional lecture format in order to improve students' learning performance. This study contributes to the improvement of teaching and learning effectiveness as well as efficiency of introductory programming classes to the benefit of instructors and students, alike.

Operating systems is a difficult subject to learn;however, little is known about these difficulties, as they have not been studied or determined by the relevant literature. The objective of this article is to specify the most difficult concepts for understanding the subject and misconceptions that students have regarding these concepts. The study was conducted through an online university over the course of an entire semester. The research data comes from the evaluations taken by nine students, which have been analyzed using qualitative methods. The most difficult concepts for students to understand include concurrent computing and the mechanisms to change the program that the processor is running (interrupts, context switches, system calls, etc.). Six misconceptions regarding these concepts have been identified, helping to determine the specific problems that need to be resolved. © 2013 ACM.
