    This three short-film project tries to comparatively evaluate the visual storytelling properties of three film techniques, live-action, 3D Computer Animation and Stop-motion (clay-mation). All of the three films aim to tell a different enjoyable story adapted to the strengths and weaknesses of each technique. To be able to establish an internal consistency and better comparability, the films are based on a common theme which is 'solitude' and a common genre which is 'supernatural horror'. This paper discusses the features of visual storytelling on each of those techniques comparatively and tries to evaluate their strengths in creating feeling and emotions. To provide a basis, this paper also examines the mythical and archetypal story behind and functions of storytelling in addition to its essentials. It also discusses the importance and necessity of 'solitude' in the context of storytelling. Solitude's role in fear is discussed as well. Eventually it blends the research and discussion material with the short-films "Rabbit! Rabbit!", "The Curtains", and "Watt" in an attempt to better understand the technical aspects of the three techniques as well as their conceptual and semantic projections on and of the story

    Mahmudov (2012, 2013) introduced and investigated some q-extensions of the q-Bernoulli polynomials ℬn,qαx,y of order α, the q-Euler polynomials ℰn,qαx,y of order α, and the q-Genocchi polynomials n,qαx,y of order α. In this paper, we give some identities for ℬn,qαx,y, n,qαx,y, and ℰn,qαx,y and the recurrence relations between these polynomials. This is an analogous result to the q-extension of the Srivastava-Pintér addition theorem in Mahmudov (2013)

    Abstract: Introduction: Community acquired pneumonia (CAP) is responsible for an important part of treatment costs across the world. Even though posterioranterior lung radiography (PALG) and direct sputum smear microscopy are required or routine diagnoses. The purpose of this study is to determine the diagnostic value of the bedside urine strip tests in CAP. Methods: Patients who attended the emergency department (ED) between from February 2016 to September 2016 with expectoration complaints and suspicion of pneumonia. The sensitivity, specificity, and accuracy rate of the urine strip tests, direct sputum smear microscopy, and PALG were calculated and analyzed using SPSS 15.0. Results: During the study period, 100 patients with pneumonia suspicion were evaluated in the ED. The sample was divided into two groups: negative and positive diagnosis of CAP. The leukocytes detecting by urine strip tests are statistical differences between the two groups (p: 0.003). The results show that the sensitivity, specificity, and accuracy rate of leukocytes detected in sputum with urine strip tests in the pneumonia diagnosis were 83.3%, 44.2% and 63% respectively. Conclusion: According to the study, it is believed that the method of determination of leukocytes with urine strip tests in sputum combined with more detailed results. They can become part of CAP diagnosis methods

    INTRODUCTION: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the usefulness of video-assisted (VL) approaches with the Macintosh direct laryngoscope for endotracheal intubation of obese patients. MATERIAL AND METHODS: Studies were obtained via a systematic search of SCOPUS, Medline, Web of Science, CINAHL, and the Cochrane Central databases. The polled relative risks (RRs) odds ratios (ODs) or standard mean differences (SMD) with 95% confidence intervals (CIs) were calculated with a random–effects model. Subgroup analyses were performed to evaluate the influence of VL types on the association. RESULTS: First intubation attempt success rate in VL and DL group varied and amounted to 94.7% vs 89.5% respectively (OR = 2.04; 95% CI: 1.21–3.42; p = 0.007) and overall intubation success rate was 99.0% vs 97.5% respectively (OR = 2.20; 95% CI: 0.45–10.67; p = 0.33). Intubation time which was 48.0 ± 37.7 for VL and 48.4 ± 37.5 seconds for DL (SMD = 0.14; 95% CI: –0.33–0.61; p = 0.56). Cormack-Lehane 1 or 2 grade during intubation using VL was observed in 95.9% of cases and was statistically significantly higher than in the case of direct laryngoscopy (79.6%; OR = 6.68; 95% CI: 3.32–13.42; p < 0.001). CONCLUSIONS: Our meta-analysis suggests that video-assisted intubation may be superior to conventional intubation in an obese patient population due to a higher first–attempt success rate, better glottis visibility, and a lower rate of intubation-related injuries.

    An investigation of control allocation methods for the ADMIRE simulation model

    Get PDF
    This paper presents a comparative study of various control allocation methods, using ADMIRE as a benchmark simulation model. The Ganged Pseudo-Inverse, Weighted Pseudo-Inverse, Cascaded Generalized-Inverse, Daisy Chain, and Linear Programming approaches are evaluated and compared against each other using open loop and closed loop analysis with Euclidean-Norm. In open-loop analysis, control allocation methods are analyzed for each approach that can produce an admissible solution and be able to attain commanded moments. Then, in closed-loop analysis, control allocation methods are compared using ADMIRE nonlinear simulation model for predefined maneuvers which are defined by multiple points in the flight envelope

    DergiPark: 289265tujesAlthough the Failure Mode and Effects Analysis (FMEA) is a systematic method of analysis, it has some shortcomings and limitations since it is a method based on intuitionistic and subjective statements of the person that rate the failure modes. In order to eliminate these constraints, the use of the method in conjunction with the grey relational analysis, which is one of the multi criteria decision making methods, helps to eliminate intuitionistic situations and prioritize the failure modes that need corrections and precautions.The classical FMEA and the FMEA integrated with the grey relational analysis approaches were applied, and their effectiveness was assessed in this study to identify and prioritize the failures and determine the measures to be taken in the wheat sieving machine production. For this purpose, first the Risk Priority Numbers (RPN) were calculated using the classical failure mode and effects analysis, then two separate grey RPNs were calculated on the assumptions that risk factors have either equal weight or different weight in the grey relational analysis-integrated FMEA approach, and the prioritization of the failures was performed. Three different RPN values obtained in the study were compared, and the priority optimizations to be made were recommended in order to prevent failures before reaching the customers as well as drawing the necessary conclusions accordingly.Hata Türü ve Etkileri Analizi (HTEA) sistematik bir analiz yöntemi de olsa hata türlerini değerlendiren kişilerin sübjektif ifadelerine dayanması sebebiyle aynı zamanda sezgisel de bir yöntemdir. Sezgilere dayanması ise uygulamada bazı eksikliklere ve kısıtlamalara yol açmaktadır. Bu problemleri ortadan kaldırabilmek için yöntemi çok kriterli karar verme yöntemlerinden biri olan gri ilişkisel analizi ile birlikte kullanmak, sezgisel durumları ortadan kaldırarak önlem alınmasını ve düzeltilmesi gereken hata türlerinin önceliklendirilmesini sağlamaktadır.Bu çalışmada buğday eleme makinesi üretimindeki hataların tespit edilerek önceliklendirilmesi ve alınacak önlemlerin belirlenmesi için klasik HTEA ve gri ilişkisel analizi ile bütünleştirilmiş HTEA yaklaşımları uygulanarak yaklaşımların etkinliği değerlendirilmiştir. Bunun için ilk önce klasik HTEA ile Risk Öncelik Sayıları (RÖS) daha sonra ise gri ilişkisel analizi ile bütünleştirilmiş HTEA yaklaşımıyla risk faktörlerinin hem eşit ağırlığa hem de farklı ağırlıklara sahip olduğu varsayımıyla iki ayrı gri RÖS hesaplanarak hataların önceliklendirilmesi yapılmıştır. Çalışma sonunda elde edilen üç ayrı RÖS değerleri karşılaştırılmış ve buna göre hataların müşteriye ulaşmaması için öncelikle yapılması gereken iyileştirmeler önerilmiş ve gerekli değerlendirmeler yapılmıştır

    This study proposes a methodology for unmanned ground vehicle (UGV) navigation in off-road environments where GPS signals are not available. The Husky-A200 at Cranfield University, United Kingdom has been used as a UGV in this research project. Due to the limited field of vision of UGVs, a UAV-UGV collaboration approach was adopted. The methodology involves five steps. The first step is divided into three phases: The aerial images of UGV from UAV are generated in the first phase. In the second phase, the UGV is detected and tracked using computer vision techniques. In the third phase, the relative pose (position and heading) between the UAV and UGV is estimated continuously using visual data. In the second step, the UAV maintain a fixed location (position and heading) relative to the UGV. The third step involves capturing aerial images from the UAV‘s mounted camera and transmitting it to the ground station instantly to create a global traversability map that classifies terrain features based on their traversability. In the fourth step, additional sensors such as LiDAR, radar, and IMU are used to refine the global traversability map. In the final step, the UGV navigates automatically using the refined traversability map. This study will focus on the first two steps of the methodology, while subsequent studies will address the remaining steps
