A Lighting Coordinate Database for 3D Art Objects

Cataloged from PDF version of article.Artists making three-dimensional art objects have an idea in their minds about how to illuminate their creations. For museums and galleries to illuminate these objects successfully according to the ideas of the artist, the types of light sources and their locations must be known. To fulfil this requirement, we propose a lighting coordinate database (LCD) to establish the coordinates of light sources. We describe two possible methods of obtaining data for this database: a computer software method and a hardware method. The head of Michelangelo's David is used to test the applicability of the two methods. In the software method, the scanned image of David's head is illuminated on the computer screen and data for the location of light sources are created. In the hardware method, a second set of data is created by illuminating a scale model of David using light emitting diodes (LED)

Unfairness in Access to and Citation of Unpublished Federal Court Decisions

An unfair system has evolved over the past fifteen years in the federal courts. The federal courts changed the concept of stare decisis. In 1972, the Judicial Conference of the United States decided that they needed to reduce the increasing workload of the federal judges. The best way to do so, they thought, was to distinguish between decisions. Some would be worthy of publication and some would not be. Thus, federal judges were instructed to separate out those rulings which would be useful to future litigants or which did more than merely repeat and mechanically apply well-settled rules of law. These decisions would be published. If a judge felt that a decision would not have precedential value, the decision and accompanying opinion would not be published. Although this seemed like a sensible solution at the time, it has created several unfavorable consequences. Since more than fifty per cent of all federal opinions are no longer published, a significant body of unpublished case law has developed. And the unfavorable consequences are directly tied to the non-publication of these decisions

Growth performances of Shibot Fish (Tor grypus) fry fed with diets containing different protein levels

Çalışmada 2,38 g ortalama ağırlığında endemik bir tatlı su balığı olan Şabut (Tor grypus ) yavruları 3 farklı protein içerikli yemle 45 gün boyunca beslenerek büyüme performansları değerlendirilmiştir. Bu değerlendirmeleri oluşturmak amacıyla deneme grupları farklı protein seviyeli yemle beslenen G1(%33 HP), G2 (%37 HP) ve G3 (%41 HP) şeklinde kurgulanmıştır. Büyüme parametreleri olarak canlı ağırlık kazancı (CAK), Yem değerlendirme oranı (YDO), Spesifik büyüme oranı (SBO), Hayatta kalma oranı, Ekonomik dönüşüm oranı (ECR) ve Ekonomik yarar indeksi (EPI) üzerine etkileri araştırılmıştır. Yavrular araştırma sonunda sırasıyla 3,42±0,16 g, 4,17±0,06g ve 4,50±0,02 g ağırlığa ulaşmıştır. Deneme sonu FCR, EPI ve ECR açısından G3 ve G2, grubu bireyleri benzer performans göstermişlerdir.In the study, the growth performances of the Shibot fish (Tor grypus) with an average weight of 2.38 g were evaluated by feeding them with 3 different protein-containing feeds for 45 days. In order to create these evaluations, the experimental groups were designed as G1 (33%), G2 (37%) and G3 (41%) fed with different protein levels. Effects on body weight gain (BWG), Feed conversion rate (FCR), Specific growth rate (SGR), Survival rate, Economic conversion rate (ECR) and Economic profit index (EPI) as growth parameters has been researched. At the end of the study, the offspring reached a weight of 3.42±0.16 g, 4.17±0.06 g and 4.50±0.02 g, respectively. G3 and G2 group individuals showed similar performance in terms of end-trial FCR, EPI and ECR

Creating a coordinate database for the lighting of three dimensional art objects

Cataloged from PDF version of article.This thesis proposes a Lighting Coordinates Database for the illumination of three-dimensional art objects. Finding and defining the weak points of current lighting methodology reinforces the importance of the need for such a database. The two methods of obtaining data for this database, the computer software and hardware method are described. For the case study, the head of Michelangelo’s David is chosen. By using the software method, the scanned image of David is illuminated and an example database is created. As the second method, a prototype of a lighting model, David’s scaled model is illuminated by using LED light sources and another example database is created.Dikel, Ekrem ErhanM.S

You turn me cold: evidence for temperature contagion

Introduction During social interactions, our own physiological responses influence those of others. Synchronization of physiological (and behavioural) responses can facilitate emotional understanding and group coherence through inter-subjectivity. Here we investigate if observing cues indicating a change in another's body temperature results in a corresponding temperature change in the observer. Methods Thirty-six healthy participants (age; 22.9±3.1 yrs) each observed, then rated, eight purpose-made videos (3 min duration) that depicted actors with either their right or left hand in visibly warm (warm videos) or cold water (cold videos). Four control videos with the actors' hand in front of the water were also shown. Temperature of participant observers' right and left hands was concurrently measured using a thermistor within a Wheatstone bridge with a theoretical temperature sensitivity of <0.0001°C. Temperature data were analysed in a repeated measures ANOVA (temperature × actor's hand × observer's hand). Results Participants rated the videos showing hands immersed in cold water as being significantly cooler than hands immersed in warm water, F(1,34) = 256.67, p0.1). There was however no evidence of left-right mirroring of these temperature effects p>0.1). Sensitivity to temperature contagion was also predicted by inter-individual differences in self-report empathy. Conclusions We illustrate physiological contagion of temperature in healthy individuals, suggesting that empathetic understanding for primary low-level physiological challenges (as well as more complex emotions) are grounded in somatic simulation

Facilitating CAD/CAM nasoalveolar molding therapy with a novel click-in system for nasal stents ensuring a quick and user-friendly chairside nasal stent exchange

Nasoalveolar molding (NAM) aims to improve nasal symmetry with a nasal stent in cleft lip and palate (CLP) patients. When plates have to be exchanged because of dentoalveolar growth or cleft reduction, the nasal stent has to be mounted onto a new plate. This procedure elongates visiting hours for patients and parents or requires second treatment sessions. This study introduces a quick-lock additive manufacturing solution for chairside nasal stent exchange called RapidNAM. A novel taping retention pin has been designed that enables nasal stent insertion. Patients with unilateral CLP were included in this study. Plaster models were digitalized and measured by two independent observers. Two methods of CAD/CAM-molding therapies were compared: (i) conventional adhesion of a nasal stent (CAD/CAM NAM);(ii) quick-lock system in which the nasal stent was transferred to another plate (RapidNAM). CAD/CAM NAM and its refinement RapidNAM significantly increased the cleft-side nasal height and tilted the nose towards symmetry. The quick-lock system minimizes wire adaptations, since the preexisting stent can be reused. The new nasal stent development seems a feasible solution to minimize visiting hours but with clinically satisfactory results. This new nasal stent system combines traditional elements of NAM with CAD/CAM-technology

On opportunistic software reuse

The availability of open source assets for almost all imaginable domains has led the software industry toopportunistic design-an approach in which people develop new software systems in an ad hoc fashion by reusing and combining components that were not designed to be used together. In this paper we investigate this emerging approach. We demonstrate the approach with an industrial example in whichNode.jsmodules and various subsystems are used in an opportunistic way. Furthermore, to study opportunistic reuse as a phenomenon, we present the results of three contextual interviews and a survey with reuse practitioners to understand to what extent opportunistic reuse offers improvements over traditional systematic reuse approaches.Peer reviewe

Daylight adaptive smart indoor lighting control method using artificial neural networks

Accurate and efficient adjustment of maintained illuminance and illuminance uniformity in indoor environments with daylight variations is a tremendous challenge, mainly due to the nonlinear and time-variant nature of lighting control systems. In this paper, we propose a smart lighting control method for indoor environments with both dimmable (controllable) and uncontrollable external light sources. Targeting an indoor environment with multiple zones, each requiring a different lighting condition and equipped with an unequal number of photodetectors and dimmable light sources, this paper presents a novel control mechanism that determines the output flux of each luminary in such a way that each zone (1) receives the required maintained illuminance, (2) illuminance uniformity conditions are met inside each zone, and (3) the power consumption is optimized. This method uses a neural network to learn the impact of each luminary on the maintained illuminance of each zone and adjust the dimming level of the luminaries to establish the required illuminance in the zones. We also rely on photodetectors to measure the daylight illuminance continuously and use it as the bias value for the neural network. The new priority value allows losing some illuminance accuracy (by allowing lager difference between the actual and required maintained illuminance values) for low-priority zones to reduce power consumption. The method has been evaluated in different test cases by chaining the widely-used DIALux tool and some MATLAB toolboxes. The evaluation results show that the method can achieve considerable accuracy by yielding an average Mean Square Error of 1.2 between the demanded and sensed illuminance values. Furthermore, when all sensors except one reference sensor are removed from each zone (to increase user comfort or reduce cost), the mean square error is less than 25.4 across all considered test cases
