Diffusive instabilities in heterogeneous systems

We investigate the behavior of a system composed of two small identical water droplets loaded with an activator-inhibitor system possessing only a single stable steady state and coupled through a third, “signaling” species able to diffuse through the interdroplet medium. Depending on whether the third species is coupled to the activator or the inhibitor, the system can exhibit wave instability, which is equivalent to out-of-phase oscillations, or Turing instability, which is equivalent to the birth of two new stationary steady states. For a large interdroplet gap, equivalent to a large time delay, droplets can undergo synchronous, in-phase oscillations. Our analysis can be extended to a system of many coupled in-line droplets, as we illustrate.
Mind in nature, nature in mind: a reply to ule

This article is a response to Ule’s ideas on the (im)possibility of naturalizing the mind. After providing a brief overview of some of the main inconsistencies in Ule’s account, I argue that a naturalistic explanation of the key feature of the mind as construed by Ule (“experiential perspectivity”) is, in fact, feasible, but only if it is complemented by an equally important shift in our conception of nature. The central part of the article consists of two steps. First, following the line of thought developed (predominantly) by Jonas and Varela, the article attempts to outline a route to the naturalization of “perspectivity” along the lines of the so-called autopoietic theory and the corresponding double dialectic of identity and sense making. Secondly, I emphasize that this is merely the first half of the story, and that the second element in Ule’s construal of the mind, “experientiality”, cannot be explained within the metaphysical framework of modern naturalism, but calls for a radical restructuring of our field of inquiry in terms of the fundamental circularity between lived experience and scientific endeavour. Thus, the process of the naturalization of life and mind needs to be reciprocated by the process of the phenomenologization of nature and reconceptualization of naturalism.
Attitude and gyro bias estimation for a flying UAV

In this paper, a nonlinear complimentary filter (x-estimator) is presented to estimate the attitude of a UAV (unmanned aerial vehicle). The measurements are taken from a low-cost SMU (inertial measurement unit) which consists of 3-axis accelerometers and 3-axis gyroscopes. The gyro bias are estimated online. A second nonlinear complimentary filter (z-estimator) is also designed, it combines 3-axis gyroscope readings with 3-axis magnetometer measurements. From the proposed estimators, the full rotation matrix R will be retrieved. Both estimators use the fact that the orientation matrix, evolving on SO(3), is not locally parameterized and thus could be used to describe any kind of 3D motion. Convergence of the two observers is theoretically proved and simulations as well as experiments are conducted on a real platform in hovering flight conditions.
Symmetrical components in the time domain and their application to power network calculations

Although the symmetrical component transformation has existed for 80 years, its application in the time-dependent form is practically restricted to the electric-machine theory. In the power systems field one uses the transformation applied to steady-state sinusoidal phasors in a nonunitary form for fault calculations. For time-domain calculations the real equivalent, 0, /spl alpha/, /spl beta/, is preferred, usually extended to 0, d, q-components. In network calculations, however, the application of time-dependent symmetrical components makes sense, since many net-component parameters are already available in this form. In this paper a short historical overview of the symmetrical-component transformation and the application of unitary and orthogonal transformations are presented. From these general transformations logic choices for base quantities necessary in per unit calculations are derived. The relations between real and complex transformations, steady-state phasors and well-known sequence networks are given and illustrated through the use of some examples with asymmetrical faults.
Interactive physically based Fluid and Erosion Simulation

Realistically eroded terrain is a base of almost every outdoor visualization for simulators or computer games. In order to achieve convincing results physically based erosion algorithms are necessary. We present a new method that combines a non-expensive fluid simulation with an erosion algorithm. Both parts are running at interactive rates so the artist is able to influence the erosion process in real-time by changing simulation parameters or applying additional water to the scene. In this way, we support realism as well as design aspects during the terrain creation process. To simplify the three dimensional fluid simulation we use a newtonian physics approach that works on a two dimensional grid storing acceleration, velocity and mass. The method provides all features that are important for simulation of erosion e.g. moving, non-moving water (rivers, lakes) and evaporation. This allows us to support effects like dissolving, transportation and sedimentation of material in the erosion process.
Entire lacrimal sac within the ethmoid sinus: outcomes of powered endoscopic dacryocystorhinostomy

Background The aim of this study was to report the outcomes of powered endoscopic dacryocystorhinostomy (PEnDCR) in patients with lacrimal sac within the sinus. Materials and methods Retrospective analysis was performed on all patients who underwent PEnDCR and were intraoperatively documented to have complete lacrimal sac in sinus. Data collected included demographics, clinical presentations, associated lacrimal and nasal anomalies, intraoperative findings, intraoperative guidance, complications, postoperative ostium behavior, and anatomical and functional success. A minimum follow-up of 6 months postsurgery was considered for final analysis. Results A total of 17 eyes of 15 patients underwent PEnDCR using standard protocols, but with additional intraoperative guidance where required and careful maneuvering in the ethmoid sinus. The mean age of the patients was 37.2 (range 17–60) years. Of the unilateral cases, 69% (nine of 13) showed left-side predisposition; 80% of patients showed regurgitation on pressure over the lacrimal sac area. Associated lacrimal and nasal anomalies were observed in 13.3% (two of 15) and 40% (six of 15), respectively. At a mean follow-up of 6.6 months, anatomical and functional success were observed in 93.3% (14 of 15). One patient showed failure secondary to cicatricial closure of the ostium. Conclusion An entire sac within an ethmoid sinus poses a surgical challenge. Good sinus-surgery training, thorough knowledge of endoscopic anatomy, careful maneuvering, and use of intraoperative navigation guidance result in good outcomes with PEnDCR.
Predicting Eclipse Bug Lifetimes

In non-trivial software development projects planning and allocation of resources is an important and difficult task. Estimation of work time to fix a bug is commonly used to support this process. This research explores the viability of using data mining tools to predict the time to fix a bug given only the basic information known at the beginning of a bug's lifetime. To address this question, a historical portion of the Eclipse Bugzilla database is used for modeling and predicting bug lifetimes. A bug history transformation process is described and several data mining models are built and tested. Interesting behaviours derived from the models are documented. The models can correctly predict up to 34.9% of the bugs into a discretized log scaled lifetime class.
TOMTAC: translating object motion to actuator control

This paper describes a software abstraction method to simplify the programming of a common class of load processing machines in which the machine's actuators cannot usually manipulate a single load independently of other loads. The abstraction allows programmers to program load behavior directly, with an underlying control engine that automatically converts load behavior specifications to actuator controls. Examples from early simulations through to a commercial implementation are discussed, with dramatic savings in programming effort evidenced
Mice, Acorns, and Lyme Disease: a Case Study to Teach the Ecology of Emerging Infectious Diseases.

Ebola, Zika, the recall of contaminated lettuce – these are just a few recent outbreaks making headlines. Students should be able to connect what they learn in their biology courses to explain these events happening around them. Unfortunately, students do not necessarily make those connections. Therefore, it is important, as instructors, to provide opportunities where students engage with societal issues and problems related to course content and case studies, using headlines from the news are one way to do this. Here I describe a case study about Lyme disease that engages students in learning about the ecology of infectious disease. Lyme disease incidence has tripled in the last 15 years and is estimated to affect 300,000 Americans annually. This lesson uses an NPR news audio clip containing interviews with two disease ecologists, Rick Ostfeld and Felicia Keesing, who describe predicting Lyme disease incidence by measuring mice populations. The activities in this lesson explore factors that led to the recent surge in Lyme disease. In small collaborative groups, students analyze data figures from publications by the Ostfeld and Keesing labs (along with others) to construct an understanding of the ecology of Lyme disease and predict how changes to the ecosystem could affect Lyme disease incidence. This case study lesson could be relevant to those teaching microbiology, ecology, public health or biology for majors.
Experiments on Segmentation Techniques for Music Documents Indexing

This paper presents an overview of different approaches to melody segmentation aimed at extracting music lexical units, which can be used as content descriptors of music documents. Four approaches have been implemented and compared on a test collection of real documents and queries, showing their impact on index term size and on retrieval effectiveness. From the results, simple but extensive approaches seem to give better performances than more sophisticated segmentation algorithms.
Smoke and mirrors: gathering user requirements for emerging affective systems

Emerging technologies, such as affective computing, have potential to enhance human-computer interaction (HCI). They are still at a prototype stage and effective working systems are still some years off. The problem is that much development is driven by what is technically possible at this time, rather than by what users require. By using Wizard-of-Oz (WOZ) methods to simulate a working affective system, it is possible to examine some user behaviours and preferences with such a system

This paper identifies the net benefits of OSOR.eu portal for citizens and companies in the European Union and defines the net benefit variables.
An Exploratory Study on the User Adoption of Central Cyber Government Office of the Hong Kong Government

“E-Government” is a mission-critical visionary issue faced by the public sector as it pushed the delivery of public services to a new quality standard through a new set of delivery means. However, many of the stakeholders found it hard to fully embrace this new mode of service delivery. Through the provision of e-services, stakeholders of government services expect that e-services can improve the efficiency of government departments (Gore, 1993; Information Technology and Broadcasting Bureau (ITBB), 1998). Indeed, information systems (IS) researchers have investigated the impact of information technology (IT) in public sector since the late 1970s, when personal computers were launched (Kraemer, 1977; Danziger et al., 1978). For recent research studies, their main ABSTRACT
An Unsupervised Morphological Criterion for Discriminating Similar Languages

In this study conducted on the occasion of the Discriminating between Similar Languages shared task, I introduce an additional decision factor focusing on the token and subtoken level. The motivation behind this submission is to test whether a morphologically-informed criterion can add linguistically relevant information to global categorization and thus improve performance. The contributions of this paper are (1) a description of the unsupervised, low-resource method; (2) an evaluation and analysis of its raw performance; and (3) an assessment of its impact within a model comprising common indicators used in language identification. I present and discuss the systems used in the task A, a 12-way language identification task comprising varieties of five main language groups. Additionally I introduce a new off-the-shelf Naive Bayes classifier using a contrastive word and subword n-gram model (“Bayesline”) which outperforms the best submissions.
Lattice triangulations of E 3 and of the 3-torus

This paper gives answers to a few questions concerning tilings of Euclidean spaces where the tiles are topological simplices with curvilinear edges. We investigate lattice triangulations of Euclidean 3-space in the sense that the vertices form a lattice of rank 3 and such that the triangulation is invariant under all translations of that lattice. This is the dual concept of a primitive lattice tiling where the tiles are not assumed to be Euclidean polyhedra but only topological polyhedra. In 3-space there is a unique standard lattice triangulation by Euclidean tetrahedra (and with straight edges) but there are infinitely many non-standard lattice triangulations where the tetrahedra necessarily have certain curvilinear edges. From the view-point of Discrete Differential Geometry this tells us that there are such triangulations of 3-space which do not carry any flat discrete metric which is equivariant under the lattice. Furthermore, we investigate lattice triangulations of the 3-dimensional torus as quotients by a sublattice. The standard triangulation admits such quotients with any number n ≥ 15 of vertices. The unique one with 15 vertices is neighborly, i.e., any two vertices are joined by an edge. It turns out that for any odd n ≥ 17 there is an n-vertex neighborly triangulation of the 3-torus as a quotient of a certain non-standard lattice triangulation. Combinatorially, one can obtain these neighborly 3-tori as slight modifications of the boundary complexes of the cyclic 4-polytopes. As a kind of combinatorial surgery, this is an interesting construction by itself. ∗For an extended abstract of this paper in two parts, see [6] and [24].

Women Athletes’ Self-Compassion, Self-Criticism, and Perceived Sport Performance

Many difficult and painful sport experiences for young women athletes are at least partially due to their harsh self-criticism and negative performance evaluations. One potential resource for young women athletes to manage these experiences is self-compassion, a healthy self-attitude premised on being kind and understanding toward oneself during times of pain and failure. The purpose of this study was to explore if self-compassion was related to sport performance and if self-compassion accounts unique variance beyond self-criticism in women athletes’ perceived sport performance. Women athletes (N = 82, Mage = 18.77 years) from a variety of sports and competition levels completed measures of perceived sport performance, self-compassion, and self-criticism in sport around a scheduled competition. Self-compassion was negatively correlated with self-criticism, r = −. 61, p < . 001 and positively correlated with perceived sport performance, r = . 29, p < . 01. Further, self-criticism was not related to women athletes’ perceived sport performance. Hierarchical regression analyses revealed that self-compassion contributed 5.4% unique variance beyond self-criticism in women athletes’ perceived sport performance. The results of this research suggest that extending compassion toward the self may be important for women athletes’ sport performance, whereas self-criticism does not play a role in perceived sport performance.

For a special class of uniform diluted nets, these quantities are found to depend basically on two integrated characterist ics of network elements .
Correlation-based patch localization for face recognition

With patch-based approaches, it is aimed to tackle the factors such as illumination, pose changes and partial occlusions that are faced in real world applications and complicates the face recognition problem. For patch-based face recognition systems to work robustly, patch locations should correspond to similar image content. In this paper, we propose two patch localization schemes for patch-based face recognition in order to make patch locations to correspond to same area in all of the face images and the image contents of the patches as close as possible. Our experimental results show that with either of the localization schemes, higher recognition results are obtained especially on the partially occluded face images with scarves or sunglasses.
Drug Administration Errors in Hospital Inpatients: A Systematic Review

Context Drug administration in the hospital setting is the last barrier before a possible error reaches the patient. Objectives We aimed to analyze the prevalence and nature of administration error rate detected by the observation method. Data Sources Embase, MEDLINE, Cochrane Library from 1966 to December 2011 and reference lists of included studies. Study Selection Observational studies, cross-sectional studies, before-and-after studies, and randomized controlled trials that measured the rate of administration errors in inpatients were included. Data Extraction Two reviewers (senior pharmacists) independently identified studies for inclusion. One reviewer extracted the data; the second reviewer checked the data. The main outcome was the error rate calculated as being the number of errors without wrong time errors divided by the Total Opportunity for Errors (TOE, sum of the total number of doses ordered plus the unordered doses given), and multiplied by 100. For studies that reported it, clinical impact was reclassified into four categories from fatal to minor or no impact. Due to a large heterogeneity, results were expressed as median values (interquartile range, IQR), according to their study design. Results Among 2088 studies, a total of 52 reported TOE. Most of the studies were cross-sectional studies (N=46). The median error rate without wrong time errors for the cross-sectional studies using TOE was 10.5% [IQR: 7.3%-21.7%]. No fatal error was observed and most errors were classified as minor in the 18 studies in which clinical impact was analyzed. We did not find any evidence of publication bias. Conclusions Administration errors are frequent among inpatients. The median error rate without wrong time errors for the cross-sectional studies using TOE was about 10%. A standardization of administration error rate using the same denominator (TOE), numerator and types of errors is essential for further publications.
TEI-Encoding of a Core Explanatory Dictionary of Romanian

The efforts on development of large Lexical DataBases (LDB) are just emerging in most of the CE-countries. CONCEDE is an EU project aiming at harmonising the methodologies, tools and (to a less extent) resources for building LDBs for six CElanguages: Bulgarian, Czech, Estonian, Hungarian, Romanian and Slovene. The paper addresses the specific problems concerning the process of TEI encoding of the Romanian Explanatory Dictionary. The Romanian Explanatory Dictionary (DEX, second edition, 1996) is the reference dictionary of Romanian and it was developed by the Institute for Linguistics of the Romanian Academy and published by the Univers Enciclopedic Publishing House. DEX is meant for a wide public and therefore the lexicographic content is relatively rich with head-words belonging to what is generally called a basic vocabulary for one language, including regional variants, but containing also various technical or specialised terms as well as various neologisms and recent lexical imports.

An Outcome Evaluation Study on Internet Addiction

The internet, which has been the most fast growing communication tool of the history, changes our life and its excessive use causes various problems. Many studies on the Internet addiction have been conducted around the world. However, most of these studies deal with psychological dimension of the Internet addiction and do not put sufficient emphasis on its educational dimension. In this research, we aimed to analyze the studies according to variable frequency, work group, data collection tool, research methods and distribution of studies among countries. This study aims to evaluate the results of the publications that are found in the journals “Computers in Human Behavior”, “Computers and Education” and in the database of Ulakbim Turkiye with the keyword “Internet addiction” which were published between 2009 and 2012. This study will give insight into the existing studies and their shortcomings and it will also provide guidance for further research
Design and implementation of aperture coupled stacked microstrip patch antennas for satellite TT&C applications

The design and fabrication of aperture coupled stacked microstrip patch antennas for TT&C uplink and downlink system in satellite is described in this paper. Two antennas are designed here of which one operates at an uplink frequency of 6.4GHz and the other antenna operating at a downlink frequency of 4.2 GHz. Stacking configuration is implemented in this design to enhance the gain the gain of the antennas. To obtain a wider bandwidth Rohacell Foam substrate (εr=1.05) of thickness 6mm is used for the radiating elements. Teflon Fiber Glass (TFG) substrate is used for the feedline, to reduce spurious radiation. The fabricated antennas weigh about 35-40 grams that makes them suitable for satellite applications. The design of the antennas for uplink and downlink system is described and the comparison of simulated results with measured results is presented.
