On Routing, Backbone Formation and Barrier Coverage in Wireless Ad Hoc and Sensor Networks

On Routing, Backbone Formation and Barrier Coverage in Wireless Ad Hoc and Sensor Networks Mona Mehrandish, Ph.D. Concordia University, 2011 In this thesis, we provide some primitives for wireless ad hoc and sensor networks to facilitate applications such as disaster relief, community mesh networks, area monitoring and surveillance, and environmental monitoring. We introduce a local learning algorithm for routing that uses feedback from neighbors to avoid voids in the network. After five retrials, our algorithm achieves almost 100% delivery rate and has a stretch factor close to that of greedy routing. We then give an algorithm for the construction of a connected dominating set to serve as a data gathering and dissemination backbone in networks modeled by unit disk graphs as well as quasi unit disk graphs. We also consider the more general case of nodes with different transmission ranges modeled by disk graphs and we give an algorithm for the construction of a strongly connected dominating and absorbent set. Both our backbone construction algorithms are local and have constant approximation ratio. Through extensive simulations, we show that our algorithms outperform the existing algorithms for the same problems. Finally, we study problem of covering a barrier with mobile sensors in order to detect intruders as they cross the border of a protected area. We consider the problem of assigning final positions to sensors to provide maximum coverage of the barrier while minimizing the maximum movement of any sensor on both multiple line barriers as well as circular barriers. Furthermore, we consider the problem of minimizing the number of sensors moved so as to achieve maximum coverage of multiple line barriers as well as a circular barrier. For both our barrier coverage problems, we consider all possible scenarios depending on whether complete coverage is possible or not, and if complete coverage is not possible, whether the coverage is contiguous or non-contiguous. For each case, we either give efficient polynomial algorithms or we show the problem to be NP-hard.
IDENTIFYING LEXICAL PARAPHRASES FROM A SINGLE CORPUS: A CASE STUDY FOR VERBS

This paper studies the potential of identifying lexical paraphrases within a single corpus, focusing on the extraction of verb paraphrases. Most previous approaches detect individual paraphrase instances within a pair (or set) of “comparable” corpora, each of them containing roughly the same information, and rely on the substantial level of correspondence of such corpora. We present a novel method that successfully detects isolated paraphrase instances within a single corpus without relying on any a-priori structure and information. A comparison suggests that an instance-based approach may be combined with a vectorbased approach in order to assess better the paraphrase likelihood for many verb pairs.

Conception et réalisation de la partie numérique d'un simulateur matériel pour les canaux de propagation MIMO

Le besoin d'ameliorer la capacite des reseaux sans-fil, pour la transmission de donnees et les applications multimedia des systemes de communications numeriques, a amene a s'interesser aux techniques de communication MIMO (Multiple Input Multiple Output) pour augmenter le debit et la qualite des transmissions. Les systemes MIMO se servent de reseaux d'antennes, a la fois a l'emission et a la reception d'une communication radio et ainsi exploitent la dimension spatiale pour la transmission de l'information. Les performances experimentales d'un systeme de communication peuvent etre evaluees en utilisant un simulateur materiel du canal de propagation. Cette these a pour objectif la conception et la realisation de la partie numerique d'un simulateur materiel pour les canaux de propagation MIMO, pour les reseaux UMTS et WLAN. La simulation materielle du canal radio assure la vitesse de traitement necessaire. D'autres avantages de la simulation materielle sont l'evaluation des performances en temps reel et la comparaison de divers systemes de radiocommunication dans un canal de propagation variant dans le temps, dans les memes conditions de test. L'etude de faisabilite a permis d'etablir deux approches, l'une pour les environnements indoor, l'autre pour les environnements outdoor. Les architectures numeriques proposees ont ete etudiees et implementees dans un composant programmable FPGA. L'evaluation des performances et de la complexite montre l'interet de ces architectures. Ce travail a ete realise dans le cadre du projet PRIR SIMPAA 2, avec le soutien de la Region Bretagne.

The Data Center Network L1 Switch Protocol

Chuck Thacker et al. have proposed a data center network design using FPGAs to implement the switching infrastructure [2]. Inside each switch, the design uses time slot circuit switching of data cells via a distributed crossbar in the data plane and besteffort forwarding of control messages via a high-speed ring in the control plane. The goal is to produce a system with minimum total complexity. Existing networks are extremely complex, have many different failure modes, and are difficult to scale out to the size of a large data center. The design fits in the context of a data center built in shipping containers. Each container holds a large number of servers and L0 switches, and holds two, top-level L1 switches, called A and B. Cables are run between all the containers to form a complete interconnection graph of the A L1 switches and likewise for the B L1 switches. This paper presents a TLA+ [1] specification of the L1 switch infrastructure.
A Scale for Measuring Email Overload

We present an eight-point scale of email overload to assess users’ feelings of email overload. Based on previous research [4], we designed a survey to examine email overload. 292 subjects filled out the survey as part of a software deployment. Eight of our questions worked together well as a scale, which can be used to evaluate the effectiveness of future email systems, as well as to explore current behavior. We show that the scale links well to user behavior.
Automatic Processing and the Unitization of Two Features.

Abstract : In a series of experiments conjunction target detection search (color and shape) was compared with single feature search (color or shape). With appropriate training and sufficient practice, subjects could unitize the features in conjunction condition. Unitization was defined as occurring when performance of the conjunction condition was similar to performance on a single feature condition. In four visual search experiments, performance on conjunctions and single feature shape searches was highly similar across three criteria: (1) slope, (2) positive to negative slope ratios, and (3) percent variance accounted for by the linear component. In another experiment, unitization was shown to be dependent on the type of mapping, either consistent or varied, in a multiple-frame detection experiment. Two other experiments further examined characteristics of single and conjunction feature conditions. In one, the stability of the integral-separable dimension distinction was examined across time. Problems with this approach and distinctions between integrality and unitization were discussed. Another experiment compared single feature and conjunction conditions in a texture segregation task. With training, conjunction performance was about equal to or better than initial single feature conditions. The relationships between unitization and automatic processing were discussed. (Author)

Bacterial genome reductions: Tools, applications, and challenges

Bacterial cells are widely used to produce value-added products due to their versatility, ease of manipulation, and the abundance of genome engineering tools. However, the efficiency of producing these desired biomolecules is often hindered by the cells’ own metabolism, genetic instability, and the toxicity of the product. To overcome these challenges, genome reductions have been performed, making strains with the potential of serving as chassis for downstream applications. Here we review the current technologies that enable the design and construction of such reduced-genome bacteria as well as the challenges that limit their assembly and applicability. While genomic reductions have shown improvement of many cellular characteristics, a major challenge still exists in constructing these cells efficiently and rapidly. Computational tools have been created in attempts at minimizing the time needed to design these organisms, but gaps still exist in modelling these reductions in silico. Genomic reductions are a promising avenue for improving the production of value-added products, constructing chassis cells, and for uncovering cellular function but are currently limited by their time-consuming construction methods. With improvements to and the creation of novel genome editing tools and in silico models, these approaches could be combined to expedite this process and create more streamlined and efficient cell factories.
A Comparative Evaluation of Program Comprehension Measures

This paper describes an experiment to evaluate measures of program comprehension. The wide variety of approaches to measuring comprehension means that it is diff icult to compare measures and have confidence in the reliabilit y and accuracy of measures. Following a review of comprehension measures employed in a number of empirical studies, four essential measures maintenance, mental simulation, static and subjective (self-ranking) are identified. These measures are then evaluated using a group of 157 novice programmers. The results indicate that the measures based on mental simulation are the most reliable, followed by maintenance based tasks. Static tasks appear to be notoriously unreliable, and subjective measures are cheap and worth using (along with another measure). Advice is also given on the creation of questions to measure comprehension.
Long-term use of renin-angiotensin-system inhibitors after acute myocardial infarction is not associated with survival benefits: Analysis of data from the Korean acute myocardial infarction registry-national institutes of health registry

Introduction Renin-angiotensin-system inhibitors (RASi) have shown survival benefits after acute myocardial infarction (MI), but the role of routine long-term use of RASi remains unclear. Thereby, we explored the therapeutic effects of RASi medication at 1-year follow-up from acute MI. Methods Using the nationwide Korea Acute Myocardial Infarction Registry-National Institutes of Health (KAMIR-NIH) registry, we included and analyzed 10,822 subjects. Patients were stratified into those taking RASi at 1-year follow-up (n = 7,696) and those not taking RASi at 1-year follow-up (n = 3,126). Patients were followed up for 2-years from the 1-year follow-up; 2-year all-cause mortality and cardiac mortality were analyzed as primary and secondary outcomes, respectively. Results The use of RASi at 1-year follow-up was not associated with decreased all-cause mortality (log-rank P = 0.195) or cardiac mortality (log-rank P = 0.337). In multivariate analyses, RASi medication at 1-year follow-up did not reduce all-cause mortality (P = 0.758) or cardiac mortality (P = 0.923), while RASi medication at discharge substantially reduced 1-year all-cause and cardiac mortality. Treatment with either an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker at 1-year follow-up did not show survival benefits from 1-year follow-up, respectively. The use of RASi at 1-year follow-up did not show a prognostic interaction between previous history of chronic kidney disease, post-MI acute heart failure, concomitant use of beta-blockers at 1-year follow-up, or 1-year LVEF. Conclusion Acute MI patients taking RASi at 1-year follow-up were not associated with improved 2-year all-cause mortality or cardiac mortality from the 1-year follow-up. This study provides valuable information regarding tailored medication strategy after acute MI. Clinical trial registration [www.ClinicalTrials. gov], identifier [KCT0000863].
Multi-variable assessment of green stormwater infrastructure planning across a city landscape: Incorporating social, environmental, built-environment, and maintenance vulnerabilities

Green stormwater infrastructure (GSI) is an increasingly popular tool to meet federal water regulations for stormwater quality and quantity, while assuaging urban flooding. While cities across the United States implement GSI into their planning processes, they are also potentially affecting the local communities that are receiving these GSI through social, ecological, physical, and economic impacts. Flooding is impacting urban communities by damaging homes and infrastructure, degrading ecosystems, and exacerbating social inequities. In the planning process, there is an acute need for the consideration of the equitable distribution of GSI in addition to technical and engineering needs. This study examines multiple aspects of vulnerability to local flooding impacts—social, environmental, and infrastructural—across a city landscape to identify those communities that have a greater need for GSI. Given the city of Philadelphia is a leader in GSI implementation in the United States, we use it as our research setting where we create citywide, multifaceted vulnerability indices that account for the spatial distribution of social, built environment, and maintenance vulnerabilities to flooding events. In addition to these indices, a GSI type decision table was created to suggest more equitable placements of different GSI types based on their maintenance needs and expected co-benefits. The results of this study reveal unequal distribution of social and built-environment vulnerabilities in the city at the Census block group scale, with high social vulnerability consistently spread across the central, southwest, and northwest neighborhoods of Philadelphia. Potential areas of severe GSI maintenance impacts appear to be concentrated in the downtown neighborhoods, while overall vulnerability appears elevated throughout the downtown and northwest neighborhoods. These results indicate that some communities in Philadelphia are highly vulnerable and should be prioritized for GSI implementation. In addition, the type of GSI implemented should be optimized to address the specific vulnerability impacts in different areas. A multifaceted vulnerability approach to planning can be applied in multiple areas of climate adaptation equity, with future studies continuing to update and add more dimensions of vulnerability where and when applicable.
Eliciting and characterizing students' mental models within the context of engineering design

Students’ harbor various alternative conceptions about scientific phenomenon. These conceptions arise as students interact with the natural world and construct mental models that enable them to make sense of these interactions. Identifying students conceptions prior to or after instruction allows educators to tailor lessons to the needs of the students. Effective science instruction can assist students in transitioning from alternative conceptions to more scientifically accurate ideas. A draw-and-explain task was created to provide a snapshot of students’ mental models of the cause of the seasons. Inductive analysis was used to identify and characterize students’ mental models. Results indicated students’ held five mental models of the four seasons. Implications suggest that identifying students’ mental models may provide predictive and explanatory power for understanding the interaction between students’ science conceptual understanding and engineering design. Introduction Students enter the science classroom equipped with ideas, or mental models, about how the world works (Driver, Guesne, & Tiberghien, 1985; Osborne & Freyberg,
Prognosis of cervical cancer using image analysis of cell nuclei

Today, clinical staging and tumor volume are the most important features influencing the choice of treatment and indicating the outcome of cervical cancer. However, within each stage there is significant variation in patient survival. Hence, there is a need for better prognostic factors. The aim of this study was to analyze morphological and textural nuclear features as prognostic factors in early cervical cancer (stage IB). Another goal was to analyze the statistical dependency between cells taken from the same patient. The study included 113 patients, and about 100 Feulgen stained cells from each patient were analyzed. Bayesian classification on independent training and test sets has been performed. To test the importance of the statistical dependency between cells from the same patient we also used a second approach. We estimated the parameters by utilizing only 50% of the cells of each patient in the training data and then tested the classification rule on the remaining 50% of the cells from the same patients. So significant prognostic factors were found in this study using nuclear image analysis. The estimated correct classification rate (CCR) of the training data was 80%, while the independent test data gave a CCR of 50%. Training and testing of cells from the same patients showed dependency between cells taken from the same specimen, with a CCR of about 80% for both the training and the dependent test data. When testing the classification rule on the independent data, which included new patients, a CCR of 50% was achieved. This study demonstrates the need of an independent data set to evaluate the performance of the classifier and that different cells taken from the same patient cannot be used as independent data. Moreover, only squamous epithelial cells were included in this study. We believe that the cell type involved in this study may be a possible reason for not finding any prognostic factors in early cervical cancer using nuclear image analysis.
