LCT image recognition for cervical cells based on BP neural network

Globally, cervical cancer is a kind of common malignant tumor second only to breast carcinoma for women. In China, the morbidity has been dramatically rising with a trend that the patients are younger and younger. Each year, about 30 thousand Chinese females died for this disease. Screening, early detection and treatment are very important in reducing the morbidity and mortality. In this paper, we will classify the segmented single cervical exfoliated cell nuclei using BP neural network. By extracting an optimized feature parameter subset of the numerous candidate parameters of the nucleus with the principal component analysis (PCA) method, the highly statistical correlation between feature parameters that may exists is removed, and the runtime efficiency of the computer aided screening system has been greatly improved, which also leads to a more satisfying recognition result.
MobIES: extending mobile interfaces using external screens

Recent mobile phones allow users to perform a multitude of different tasks. Complexity of tasks challenges the design of mobile applications in many ways. For instance, the limited screen space of mobile devices allows only a small number of items to be displayed. Therefore, users often have to change the view or have to resize the displayed content (e.g., images or maps) to view the required information. We present the system MobIES, which allows users to extend the mobile interfaces of their mobiles phones using external screens. Users connect their mobile phone with an external display by holding it on the border of the external display. When the connection is established, the user interface of the currently active mobile application is distributed on the phone and the external screen. This enables users to take advantage of using existing screens in their environments and temporarily benefit from an extended screen space. In this paper, we discuss the concept of MobIES and present a prototype implementation.
Mining Console Logs for Large-Scale System Problem Detection

The console logs generated by an application contain messages that the application developers believed would be useful in debugging or monitoring the application. Despite the ubiquity and large size of these logs, they are rarely exploited in a systematic way for monitoring and debugging because they are not readily machine-parsable. In this paper, we propose a novel method for mining this rich source of information. First, we combine log parsing and text mining with source code analysis to extract structure from the console logs. Second, we extract features from the structured information in order to detect anomalous patterns in the logs using Principal Component Analysis (PCA). Finally, we use a decision tree to distill the results of PCA-based anomaly detection to a format readily understandable by domain experts (e.g. system operators) who need not be familiar with the anomaly detection algorithms. As a case study, we distill over one million lines of console logs from the Hadoop file system to a simple decision tree that a domain expert can readily understand; the process requires no operator intervention and we detect a large portion of runtime anomalies that are commonly overlooked.
Agent chaining: an approach to dynamic mobile agent planning

The distributed agent concept has become a new computing paradigm in Internet distributed computing, including mobile computing. Mobile agent planning is one of the most important techniques for completing a given task efficiently. The static planning technique may not be the best approach in real network environments. For better performance, it is necessary that mobile agents be more sensitive to the network conditions. We propose a dynamic planning algorithm, named n-ary agent chaining, which is based on static mobile agent planning. Mobile agents can change their itinerary dynamically according to current network status using the proposed algorithm. The proposed algorithm also takes into account the locality of target nodes on the network. Thus, with a properly chosen locality factor it can adapt to realistic network situations. Agents reproduced from the original one, named cloned agents, process the unprocessed nodes in the proposed algorithm. Since the turn-around time can be calculated mathematically with known network statistics before launching the agents, the proposed algorithm is suitable for agent problem domains with deadline constraints.
An Image Curvature Microscope

This paper presents a review, analysis and comparison of numerical methods implementing the curvature motion and the affine curvature motion for 2D images, shapes, and curves. These curvature scale spaces allow, in principle, to compute an accurate multiscale curvature in digital images. The fastest and most invariant of them can be used in a complete image processing chain. This numerical chain simulates the accurate sub-pixel evolution of an image by mean curvature motion or by affine invariant curvature motion. To do so, it lets all the level lines of the image evolve by curvature shortening (of affine shortening), computes the image curvature directly on the smoothed level lines, and reconstructs the evolved image and its curvatures in an intrinsic, grid-independent representation. The paper describes a careful implementation of this chain, and analyzes its effects on many examples. The microscopic visualization of an image curvature map reveals after processing many image details. This image process improves graphic images, gets rid of compression and aliasing effects. It also gives an accurate tool to explore the validity of Attneave's and Julesz theories on shape perception and texture discrimination. The " curvature microscope " runs on line for any image at 1. Introduction. Attneave's founding 1954 paper [4] on image perception anticipated the numerical analysis of digital pictures. He stated that in images: " information is concentrated along contours (i.e., regions where color changes abruptly), and is further concentrated at those points on a contour at which its direction changes most rapidly (i.e., at angles or peaks of curvature) ". Yet, because of noise and alias-ing effects, the direct computation of curvatures on a raw image is impossible and depends anyway on a smoothing scale.
An analysis of vowels across word boundaries in Veracruz, Mexican Spanish

This project examines vowels in hiatus across word boundaries in Spanish. Our findings are based on a corpus of seven female speakers of the Veracruz variety of Mexican Spanish. Previous research on vowel transitions has proposed several possible outcomes for vowel combinations across word boundaries in Spanish: hiatus, diphthong, reduction or deletion of one vowel, or creation of a new vowel. The purpose of this project was to investigate the conditions under which these outcomes actually occur in running speech using spectrographic analysis. In terms of hiatus, our results support those of a study conducted on the Spanish of northern New Mexico/Southern Colorado by Alba (2006), which concluded that maintaining hiatus was not the preferred outcome. Likewise, in the present study, 94% of our 148 tokens showed non-maintenance of hiatus. Our data did not clearly reveal a single preferred outcome among the non-maintenance tokens, but rather a mixture of tendencies. These varied widely by vowel combination and speaker. Another surprising outcome that deserves attention is centralization. Centralization was present in all four vowel combinations, occurring more frequently than anticipated, given that it is thought not to occur in Spanish.
Automatic Acquisition of Paradigmatic Relations Using Iterated Co-occurrences

We introduce the notion of iterated co-occurrences, which can be obtained by performing the calculation of statistically significant cooccurrences not on sentence level, but on co-occurrence sets of previous calculations. The underlying mechanisms are explained in detail and we give reasons, why this iteration results in sets of semantically homogeneous words. These can be used for the automatic acquisition of paradigmatic relations in order to semi-automatically extend lexical-semantic word nets or thesauri, widening the acquisition bottleneck. A small evaluation for synset expansion for German language and some discussion conclude the work.
Ontology-Based Semantic Interoperability in Emergency Management Candidate : Mandana Sotoodeh Supervisor : Dr

Emergency management is " the discipline and profession of applying science, technology, planning and management to deal with extreme events that can injure or kill large numbers of people, do extensive damage to property, and disrupt community life " (Drabek & Hoetmer, 1991). The recent disasters such as Katrina and Southeast Asia tsunami have reinforced the need for development of a comprehensive approach to emergency management (Public Safety Canada, 2005). Comprehensive Emergency Management refers to the development of a capacity for handling emergency tasks in all phases-mitigation, preparedness, response and recovery-in connection with all types of disaster agents by coordinating the efforts and resources of all players-non-governmental organizations, government agencies and private sectors-involved (Britton, 1999). In this report, emergency management refers to major incidents and disasters, and emergency management and disaster management are used interchangeably. One of challenges for the people in emergency management is a lack of accepted terms. People in the domain have not found common ground with respect to the language that is used to define and articulate the field (Britton, 1999). In Section 3, we will provide some examples of this problem in the context of disaster research where, for example, the concept of risks is sometimes confused with hazards or vulnerabilities, or, variations that exist in the definitions of a disaster. This problem impedes many interdisciplinary developments, and causes confusion and distancing between the researchers and the practitioners. Another challenge is the problem of interoperability between information technologies devised for emergency management. There has been substantial research programs aimed at strengthening IT-enabled capabilities for emergency management. They intend to improve the exchange of critical information, support better decision making, and increase the flexibility of organizations involved. Interoperability issues arise when such technologies need to share information. Interoperability generally comes in three aspects: (1) technical: compatibility of message formats (2) semantic: 4 terminology and definitions, and (3) organizational: practices and procedures (National Research Council, 2007). This research addresses the problem of semantic interoperability between people or application systems in the emergency management domain. The objective is to identify and evaluate several solutions to this problem that could be adopted by any governmental and private agencies involved in the domain. The outline of the proposal is as following. This chapter provides background information and related work to develop the problem statement. Chapter 2 describes the summary of the accomplished work. Chapter 3 outlines the plan for completion …
Autonomous Rovers for Human Exploration of Mars

Autonomous rovers are a critical element for the success of human exploration of Mars. The robotic tasks required for human presence on Mars are beyond the ability of current rovers; these tasks include landing-site scouting and mining, as well as emplacement and maintenance of a habitat, fuel production facility, and power generator. These tasks are required before and also during human presence; the ability of rovers to o oad work from the human explorers will enable the humans to accomplish their mission. Performing these tasks will require signi cant advances in rover autonomy and will require improvements in robustness, resource utilization, and failure recovery. The Path nder mission demonstrated the potential for robotic Mars exploration, but at the same time indicated the need for more rover autonomy. The highly ground-intensive control with infrequent communication and high latency limited the e ectiveness of the Sojourner rover. Advances in rover autonomy o er increased rover productivity without risk to rover safety. Towards this end, we are developing an integrated on-board executive architecture that incorporates robust operation, resource utilization, and failure recovery. This work draws from our experience with the Deep Space One autonomy experiment, with enhancements to ensure robust operation in the face of the unpredictable, complex environment that the rover will encounter on Mars. Our ultimate goal is to provide a complete agent architecture for rover autonomy. The complete architecture will include long-range mission and path planning, self-diagnosis and fault recovery, and continual monitoring and adjustment of execution resources. The architecture will enable robust operation over long ranges of time and distance, allowing rovers to perform complex tasks in a planned and opportunistic manner and serve as an intelligent, capable tools for human explorers.
Hemodynamic Responses and the Sustainability of Force during Submaximal Isometric Handgrip Exercise: Are There Sex Differences?

Background: Sex related differences in the control of blood pressure at resting conditions have been previously reported. Studies in rodents have also shown that during exercise, female animals have an enhanced capacity to inhibit sympathetic vasoconstriction than male animals. Aims: To examine whether sex differences exist in (i) systolic/diastolic blood pressure (SBP/DBP) and systemic vascular resistance (SVR) responses during handgrip exercise, (ii) the ability to sustain a predetermined target force during isometric handgrip, in young, healthy, lean adults. Study Design / Methodology: Fourty-six adults (19 men and 27 women), aged 20-27 years, underwent a protocol that included a seated rest (baseline), a 3-min handgrip at 30% of maximal voluntary contraction (MVC), and recovery. Continuous, beat-to-beat SBP/DBP and heart rate were recorded (Finapres). Handgrip force was monitored (Biopac). Results: Men had higher MVC than women (P < 0.001), both sexes exhibited similar handgrip steadiness. Men rated the exercise session fatiguing their female counterparts. remained relatively stable during handgrip in men, whereas, a decline in SVR during exercise and recovery was observed in women (P < 0.05). Conclusion: Differential hemodynamic responses during isometric exercise and recovery were revealed between young, healthy, and lean men and women. However, the steadiness and ability to sustain force during isometric exercise were not significantly different between men and women.
Cardiovascular dysfunction in patients with liver cirrhosis

Hyperdynamic syndrome is a well-known clinical condition found in patients with cirrhosis and portal hypertension, characterized by increased heart rate and cardiac output, and reduced systemic vascular resistance and arterial blood pressure. The leading cause of hyperdynamic circulation in cirrhotic patients is peripheral and splanchnic vasodilatation, due to an increased production/activity of vasodilator factors and decreased vascular reactivity to vasoconstrictors. The term “cirrhotic cardiomyopathy” describes impaired contractile responsiveness to stress, diastolic dysfunction and electrophysiological abnormalities in patients with cirrhosis without known cardiac disease. Underlying circulatory and cardiac dysfunctions are the main determinant in the development of hepatorenal syndrome in advanced cirrhosis. Moreover, the clinical consequences of cirrhosis-related cardiovascular dysfunction are evident during and after liver transplantation, and after transjugular intrahepatic portosystemic shunt insertion. Cardiovascular complications following these procedures are common, with pulmonary edema being the most common complication. Other complications include overt heart failure, arrhythmia, pulmonary hypertension, pericardial effusion, and cardiac thrombus formation. This review discusses the circulatory and cardiovascular dysfunctions in cirrhosis, examining the pathophysiologic and clinical implications in light of the most recent published literature.
Dynamic Intransitive Noninterference

Existing noninterference frameworks for reasoning about system security assume a fixed configuration of domains governed by a security policy that does not change over time. A static security policy, however, cannot express the domain interactions present in many modern system designs, which allow users to configure the set of active domains at runtime. In this paper, we generalize Rushby’s framework for static noninterference to support reasoning about the security of systems with a dynamic policy. In particular, we show that the security of a given dynamic policy system can be established by supplementing Rushby’s unwinding theorem with the new notion of policy respect .
Using multilevel call matrices in large software projects

Traditionally, node link diagrams are the prime choice when it comes to visualizing software architectures. However, node link diagrams often fall short when used to visualize large graph structures. In this paper we investigate the use of call matrices as visual aids in the management of large software projects. We argue that call matrices have a number of advantages over traditional node link diagrams when the main object of interest is the link instead of the node. Matrix visualizations can provide stable and crisp layouts of large graphs and are inherently well suited for large multilevel visualizations because of their recursive structure. We discuss a number of visualization issues, using a very large software project currently under development at Philips Medical Systems as a running example.
Molecular Gas in the Lensed Lyman Break Galaxy cB58

We have used the IRAM Plateau de Bure Interferometer to map CO (3-2) emission from the gravitationally lensed Lyman break galaxy MS 1512-cB58. This is the first detection of a molecular emission line in any Lyman break system; its integrated intensity implies a total molecular gas mass of (6.6) × 109 h M☉, while its width implies a dynamical mass of (1.0) × 1010 i h M☉ (for a flat ΩΛ = 0.7 cosmology). These estimates are in excellent concordance with nearly all parameters of the system measured at other wavelengths and yield a consistent picture of past and future star formation with no obvious discrepancies requiring explanation by differential lensing. In particular, we find that the age and remaining lifetime of the current episode of star formation are likely to be similar, the surface densities of star formation and molecular gas mass are related by a Schmidt law, and the fraction of baryonic mass already converted into stars is sufficient to account for the observed enrichment of the interstellar medium to 0.4 Z☉. Barring substantial gas inflow or a major merger, the stars forming in the current episode will have mass and coevality at z = 0 similar to those of a spiral bulge. Assuming that cB58 is a typical Lyman break galaxy apart from its magnification, its global parameters suggest that the prescriptions for star formation used in some semianalytic models of galaxy evolution require moderate revision, although the general prediction that gas mass fraction should increase with redshift is validated. The length of cB58's star formation episode relative to the time elapsed over the redshift range 2.5 ≤ z ≤ 3.5 strongly argues against scenarios in which observed LBGs cohabit their halos with a large number of similar but "dormant" systems whose starbursts have faded or not yet begun. As a useful empirical result, we find that the observed line/continuum ratio for cB58 is similar to those of high-redshift systems with quite different dust luminosities and nuclear activity levels. Finally, we report the detection of a second source close to the position of the cD elliptical in the z = 0.37 lensing cluster, which may be nonthermal continuum emission from the cD or CO line emission from a hitherto unknown background galaxy at z ~ 1.48 or ~2.73.
PETS vs . VACE Evaluation Programs : A Comparative Study

There are numerous distributed efforts on performance evaluation of computer vision algorithms. Information exchange between programs can expedite achievement of the common goals of such projects. As a step towards this, this paper presents a qualitative comparison of the VACE and the PETS programs, the synergy of which, we believe, will have a significant impact on the progress of research in the vision community. The comparison is based on the vital aspects of an evaluation project – the framework, the tasks, performance metrics and ground truth data.
Wireless Sensor Networks : Communication Mechanisms for Power-Aware Data Dissemination

A wireless sensor network is an ad hoc network consisting of numerous sensor devices (nodes). These nodes are linked via short-range ad hoc radio connections. Each node in such a network has a limited energy resource (battery), and each node operates unattended. Consequently, energy efficiency is an important design consideration for these networks. Inspired by the fact that in complex systems in nature each element follows simple rules in order to attain a common goal, we design energy efficient routing mechanisms that mimic this concept. The proposed unicast routing mechanism requires only local coordination of nodes to build a minimum cost topology (tree) on a network. Each node then uses power-aware selection to route data along a minimum cost route towards the target node. The proposed broadcast mechanism minimizes the number of rebroadcasting nodes by exploiting the broadcast nature of the wireless channel. We show that a simple local scheme executed at each node suffices to keep the number of retransmitting nodes close to a minimum number. Both communication mechanisms take into account the nodes’ limited energy resources, and thus extend the lifetimes of the sensor nodes. We evaluate the broadcast mechanism using simulation. We find that it exhibits good scalability and power-aware characteristics.
