Computer mediated expression in paint

In this thesis, we present a design and implementation of a framework for computer mediated expression. The computer's role in mediation is dual-both for enabling new forms of creative work as well as enabling creative work for populations for which it is not currently accessible, with the latter being the main focus of the work. The system consists of input, processing, and output stages. Simplicity of integration and modularity are the primary design goals which inform the architecture for the processing stage as well as the need for the interface layers to be universal and simple. Several input modalities have been realized and tested, including wearable IMU, airflow, and eye-tracking. One primary output modality has been constructed in the form of a robotic multi-color airbrush. Several evaluations were performed to assess the system's usability from a user's perspective as well as that of a developer. A survey was also conducted to evaluate the potential impact on the general public's perception of ability in the context of disability, particularly with respect to self-expression with paint.

A Study on the Non-Inductive Coils for Hybrid Fault Current Limiter Using Experiment and Numerical Analysis

A Hybrid fault current limiter (FCL) proposed by our group previously is composed of a superconducting coil, a fast switch and a bypass reactor. The superconducting coil wound with two kinds of HTS wire has zero impedance when normal current flows in the coil. However, different quench characteristics of the HTS wire generate magnetic flux in the coil when fault current flows in the coil. As a result, the fast switch was opened by the repulsive force applied to the aluminum plate above the coil. In previous studies, our group verified operating characteristics and feasibility of the fast switch. In this paper, comparison of pancake type and solenoid type non-inductive coil wound with two kinds of the HTS wire was performed by using short-circuit test and finite element method. From these results, short-circuit characteristic of a coil can be acquired and magnitude of the repulsive force and magnetic field can be analysed.
Does infectious disease influence the efficacy of marine protected areas? A theoretical framework

1. Marine protected areas are increasingly being recommended as an essential component of the management of exploited marine species, but virtually no attention has been given to the influence of parasites. This may be substantial, as a primary effect of marine reserves is to increase the density of an exploited population within the reserve relative to outside the reserve, which may facilitate parasite transmission. 2. We used a simple deterministic model of microparasitic infection in a fishery with a reserve to investigate equilibrium yield and parasite prevalence inside and outside the reserve as a function of three control variables: the proportion of habitat inside the reserve, fishing mortality and the rate of interchange between the stock and the reserve. 3. While our model is generic, we parameterized it with values that may be appropriate to the interaction between abalone and Rickettsia. 4. The presence of a pathogen does not necessarily decrease yield when a reserve is present, particularly if the rate of movement of adult hosts between stock and reserve is low. 5. Synthesis and applications. Pathogens have important implications for the design of marine reserves. Our modelling identifies two key considerations. First, 'fishing out' a pathogen by reducing the host population density to a level below the threshold for disease maintenance is a potential management strategy that is made more difficult by establishing a reserve. Secondly, the effect of a highly transmissible pathogen without a reserve is to cause a rapid decline in equilibrium yield for efforts beyond those that produce maximum sustainable yield, making the fishery prone to collapse. Introducing a reserve decreases yield in this case, but makes the fishery much more resistant to collapse.
A Subwavelength Element for Broadband Circularly Polarized Reflectarrays

A subwavelength element is presented for designing a circularly polarized (CP) reflectarray that converts the linearly polarized incident field of the feed into an outgoing circularly polarized field. To evaluate the performance of the designed element, a parametric study is carried out using Ansoft HFSS. Compared to the conventional near-resonant patch, the subwavelength one can realize a more similar behavior for the phase curves at different frequencies, leading to broader bandwidth. The phase shifts for both linear polarizations can be controlled by varying the x- and y-dimension of the element. A prime-focus reflectarray with this type of element has been designed and implemented, and a superior bandwidth performance has been verified, compared to a reflectarray with conventional ¿/2 elements. The measured results show that the obtained 1-dB gain and 3-dB axial ratio bandwidths of the reflectarray with subwavelength elements can reach as large as 17% and 11%, respectively.
THE IMPACT OF NATIONAL CULTURE AND INSTITUTIONAL ENVIRONMENT ON INTERNAL CONTROL DISCLOSURES

Purpose – The purpose of the present study is to empirically examine the association between, on the one hand, culture and the institutional environment and, on the other, the amount of information on internal control listed firms disclose in their annual reports. Design – This study uses unique hand-collected data from a sample of 2,172 firmyear observations for 815 distinct firms from 25 countries for the period 2005 to 2007. The amount of internal control disclosure is based on a self-constructed disclosure index comprising seven separate reportable items. Findings – The results indicate that both culture and institutional environment explain cross-national variations in the amount of information on internal control firms disclose in their annual reports after controlling for firm characteristics. Originality/value – Prior work on internal control disclosure focused on single countries and typically the US. The paper is the first to examine determinants of internal control disclosure cross-nationally.
Automatic goal inferences q

The social psychological literature on automatic social inferences has focused on one construct that helps explaining human behavior—traits (e.g., Gilbert, Pelham, & Krull, 1988; Trope, 1986; Winter & Uleman, 1984). The dispositional roots of behavior, however, go beyond relatively stable constructs such as traits to include more transient causes such as one s intentions and goals. Evidence from young infants and adult chimpanzees, knowledge acquired in the text-comprehension literature and hypotheses derived from the Automatic Causal Inferences framework (Hassin, Bargh, & Uleman, 2002), seems to converge: they all suggest that perceivers may automatically infer goals from behaviors. This paper reports four studies that examine this hypothesis. The first two use surprise cued-recall, and look at goal inferences when the road to goal achievement seems straightforward and when it seems blocked. Studies 3 and 4 use on-line methodologies—probe recognition task and lexical decision—to examine whether these inferences are made at encoding. 2004 Elsevier Inc. All rights reserved.
La Divulgación de la Información Social y Medioambiental de la Gran Empresa Española en el Período 1994–1998: Situación Actual y Perspectivas

RESUMEN El presente trabajo analiza la cantidad de información social y medioambiental divulgada en los informes anuales de las empresas españolas a lo largo del período 1994–1998, al tiempo que investiga algunos factores determinantes en la revelación de este tipo de información. Para ello se analizaron los informes anuales de una muestra de 62 grandes compañías con actividades en España pertenecientes a diversos sectores. Tras la elaboración de varios índices de divulgación de información social y medioambiental, los resultados de la investigación constatan un lento, pero sostenido crecimiento en la divulgación de este tipo de información, en particular la relacionada con el medio ambiente. Adicionalmente, las grandes empresas y las pertenecientes a los sectores de energía y de petróleo son las que divulgan mayor volumen de información, sin que la rentabilidad de la firma, la cotización de la misma o el país de procedencia de la mayoría del capital condicionen la divulgación de información social y medioambiental.
Neural fate of seen and unseen faces in visuospatial neglect: A combined event-related fMRI and ERP study

To compare neural activity produced by visual events that escape or reach conscious awareness, we used event-related MRI and evoked potentials in a patient who had neglect and extinction after focal right parietal damage, but intact visual fields. This neurological disorder entails a loss of awareness for stimuli in the field contralateral to a brain lesion when stimuli are simultaneously presented on the ipsilateral side, even though early visual areas may be intact, and single contralateral stimuli may still be perceived. Functional MRI and event-related potential study were performed during a task where faces or shapes appeared in the right, left, or both fields. Unilateral stimuli produced normal responses in V1 and extrastriate areas. In bilateral events, left faces that were not perceived still activated right V1 and inferior temporal cortex and evoked nonsignificantly reduced N1 potentials, with preserved face-specific negative potentials at 170 ms. When left faces were perceived, the same stimuli produced greater activity in a distributed network of areas including right V1 and cuneus, bilateral fusiform gyri, and left parietal cortex. Also, effective connectivity between visual, parietal, and frontal areas increased during perception of faces. These results suggest that activity can occur in V1 and ventral temporal cortex without awareness, whereas coupling with dorsal parietal and frontal areas may be critical for such activity to afford conscious perception.
The impact of food scares on price transmission along the food marketing chain

In this paper we show how regime-switching vector error correction models can be used to assess the effects of food scares on price transmission along the food marketing chain. Our empirical implementation focuses on the impacts of the BSE crisis on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. Monthly prices are used over the 1996-2005 period. A BSE food scare index is developed in order to measure the scale of the food scare crisis. Results suggest that the crisis affects beef producers and retailers differently. While consumer prices are not found to adjust to the crisis, producer prices do, though only when the scale of the food scare reaches certain minimum levels.
Parenthood and the Gender Gap : Evidence from Denmark ∗

Despite considerable gender convergence over time, substantial gender inequality persists in all countries. Using Danish administrative data from 1980-2011, we show that most of the remaining gender gap can be attributed to the dynamic effects of having children. The arrival of children leads to a long-run penalty in female earnings of 21% driven in roughly equal proportions by labor force participation, hours of work, and wage rates. Underlying this child penalty, we find clear dynamic effects of child birth on occupation, promotion to manager, and the family friendliness of the firm for women relative to men. The fraction of the aggregate gender gap that can be explained by children is strongly increasing over time—from 30% in 1980 to 80% in 2011—showing that non-child reasons for gender inequality have largely disappeared. Conditional on rich observables, the female child penalty in earnings is increasing in the relative skill of the female in the family, suggesting that mechanisms other than comparative advantage are at play. We probe into the potential role of “gender identity” effects by showing that the female child penalty is strongly related to the relative labor supply history of her parents. This is consistent with the notion that gender attitudes surrounding family and career are shaped in part by the environment in which individuals grow up. ∗Kleven: h.j.kleven@lse.ac. uk; Landais: c.landais@lse.ac. uk; Søgaard: jes@econ.ku. dk.

Reattachment of a Separated Boundary Layer on a Flat Plate in a Highly Adverse Pressure Gradient Using a Plasma Actuator

Abstract : An experimental study was performed to examine the phase-dependent response characteristics of a dielectric barrier discharge plasma flow control actuator. The actuator was investigated on a fully separated flat plate boundary layer with an adverse freestream pressure gradient distribution. The actuator was positioned downstream of the boundary layer separation. Phase-locked particle image velocimetry (PIV) was used to obtain two-dimensional velocity field measurements at thirty equally spaced phase-angles along the sinusoidal voltage input to the actuator. A subtle phase-dependence was observed in the response of the streamwise (U-velocity) component of boundary layer velocity field. No similar phase-dependence was observed in the vertical direction (V-component of velocity).
The different star formation histories of blue and red spiral and elliptical galaxies

We study the spectral properties of intermediate mass galaxies (M* ∼ 1010.7 M⊙) as a function of colour and morphology. We use Galaxy Zoo to define three morphological classes of galaxies, namely early types (ellipticals), late-type (disc-dominated) face-on spirals and early-type (bulge-dominated) face-on spirals. We classify these galaxies as blue or red according to their Sloan Digital Sky Survey (SDSS) g − r colour and use the spectral fitting code Versatile Spectral Analyses to calculate time-resolved star formation histories, metallicity and total starlight dust extinction from their SDSS fibre spectra. We find that red late-type spirals show less star formation in the last 500 Myr than blue late-type spirals by up to a factor of 3, but share similar star formation histories at earlier times. This decline in recent star formation explains their redder colour: their chemical and dust content are the same. We postulate that red late-type spirals are recent descendants of blue late-type spirals, with their star formation curtailed in the last 500 Myr. The red late-type spirals are however still forming stars ≃17 times faster than red ellipticals over the same period. Red early-type spirals lie between red late-type spirals and red ellipticals in terms of recent-to-intermediate star formation and dust content. Therefore, it is plausible that these galaxies represent an evolutionary link between these two populations. They are more likely to evolve directly into red ellipticals than red late-type spirals, which show star formation histories and dust content closer to blue late-type spirals. Blue ellipticals show similar star formation histories as blue spirals (regardless of type), except that they have formed less stars in the last 100 Myr. However, blue ellipticals have different dust content, which peaks at lower extinction values than all spiral galaxies. Therefore, many blue ellipticals are unlikely to be descendants of blue spirals, suggesting there may not be single evolutionary path for this group of galaxies.
Solving electromagnetic scattering by multiple targets with surface equivalence principle algorithm

Electromagnetic scattering by multiple homogeneous dielectric objects of arbitrary shape is solved by using the surface equivalence principle algorithm (EPA). The numerical properties of the algorithm, the accuracy of the solution and the convergence of the iterative solution, are studied by varying the permittivity contrast of the dielectric objects and the number and location of the equivalence principle surfaces enclosing the objects. In all considered EPA is found to lead to more efficient iterative solutions than the traditional method of moments formulations. However, both the solution accuracy and the convergence of the iterative solutions of EPA are found to depend strongly on the number of the equivalence surfaces.
Performance analysis of feature selection algorithm for educational data mining

Student's academic performance is the main focus of all educational institutions. Educational Data Mining (EDM) is an emerging research area help the educational institutions to improve the performance of their students. Feature Selection (FS) algorithms remove irrelevant data from the educational dataset and hence increases the performance of classifiers used in EDM techniques. This paper present an analysis of the performance of feature selection algorithms on student data set. The obtained results of the different FS algorithms and classifiers will also help the new researchers in finding the best combinations of FS algorithms and classifiers. Selecting relevant features for student prediction model is very sensitive issue for educational stakeholders, as they have to take decisions on the basis of results of prediction models. Furthermore our paper is an attempt of playing a positive role in the improvement of education quality, as well as guides new researchers in making academic intervention.
Determinants of student performance in an accounting degree programme

The objective of this study is to identify, by way of regression analysis, the factors that have a significant relationship with student performance in accounting at the third-year level at universities. This study extends the existing literature on student performance in tertiary level accounting programmes. The results can inform the selection process, as well as develop and incorporate appropriate initiatives to enhance the performance of students in these types of programmes. The sample comprises data obtained from students attempting the exit modules in the 2010 and 2011 academic years at the University of the Western Cape. Findings indicate that at the time when students finish high school, their final-year high school grades are significantly related to their performance in the final undergraduate accounting module. Interestingly, their high school mathematics grades appear to be significantly related to passing or failing Accounting 3, but not the percentage achieved in Accounting 3. After their first year, students’ Accounting 1 grades are positively and highly significantly related to their performance in Accounting 3. Similarly, after their second year, students’ Accounting 2 grades are positively and highly significantly related to their performance in Accounting 3.
Car 2 Car framework based on DDGP 3

The purpose of this paper is to provide an algorithm for the detection of free parking stalls within a multilevel garage. Obviously, we are in the condition where the parking is very busy. Using devices of the cars On Board Units (OBU) and Road Side Units (RSU) is possible to determine, with a certain error, the matrix of distances between all sensors. The way of information exchange between cars is the VANETs. Starting from the known position of the RSU and the mutual distance between all adjacent cars OBU is possible to obtain the position of all cars applying a Distance Geometry Problem (DGP) algorithm schema. Unfortunately, the complexity of these algorithms is NP-hard. Under some conditions, the DGP algorithm can switch from continuous to discrete and it can be solved with a sort of branch and pruning algorithm. We are interested in a DDGP3 that is a Discretizable Distance Geometry Problem in R3 variant to be used as a starting point for our work. The resolution of the algorithm is equivalent to the resolution of a problem of intersection between three spheres. This problem is non-linear and, in some conditions, it is possible to obtain an approximate solution with linear techniques.
Use of specific malingering measures in a Spanish sample

There are an increasing number of tests available for detecting malingering. However, these tests have not been validated for using in Spanish speakers. The purpose of this study is to explore the value of three specific malingering tests in the Spanish population. This study used a known-groups design, together with a group of analog students. The results show that both the Victoria Symptom Validity Test and the b Test can be used to detect malingering in Spanish population. However, some restrictions must be applied when the Rey 15-Item Test is administered and interpreted.
Value for Money? Community Targeting in Vote-Buying and Politician Accountability

Community targeting of vote payments — defined as the saturation of entire neighborhoods with cash prior to elections — is widespread in the developing world. In this paper, we utilize laboratory experiments conducted in the U.S. and Kenya to demonstrate that, relative to individual targeting, a vote-buying regime that distributes payments widely renders voters more tolerant of politician rent-seeking, and increases the level of politician rent-seeking observed in equilibrium. The most parsimonious model of preferences consistent with these patterns is a model in which both politicians and voters are characterized by multifaceted social preferences, encompassing reciprocity, altruism, and inequality aversion.
MMR vaccine and autism: Is there a link?

Immunization programs are among the most effective strategies in healthcare. It has succeeded in eliminating or significantly decreasing the incidence of many once common diseases. However, regarding immunization, safety appears to be an increasing concern and this constitutes a real threat to the success of immunization programs [1]. New or long standing safety allegations may become threats to vaccination programs as they may erode public confidence on vaccines and lead to a consequent fall in vaccination coverage [2]. Such concerns may be fueled by the dissemination of anecdotal reports of alleged vaccine reactions by the media that cause parents and even some healthcare providers to question the justification for immunization.
Phytochemical Screening and Pharmacological Applications of Some Selected Indian Spices

Spices have been added to foods since ancient times, not only as flavoring agents, but also as folk medicines and food preservatives. The current investigation deals with the extraction and phytochemical analysis of Syzygium aromaticum, Piper nigrum and Cinnamomum verum which are one of the most important spices used in India. The presence of phytochemicals including phytosterols, saponins, alkaloids, phenolic compounds, tannins, proteins, glycosides, flavonoids, carbohydrates, quinones, coumerin, terpenoids, anthocyanins and emodins were determined for their presence. Phytosterols, glycosides and terpenoids were present in all the species. Saponins and carbohydrates are present only in Syzygium aromaticum, while proteins are found in Piper nigrum. While anthocyanins and emodins were absent in the extracts of all the studied spices. It is concluded that the extracts of all the studied spices consists of important constituents having pharmacological activities.
