Opis:
Artykuł przynosi wnikliwą analizę produktywnych semantycznie cech struktury wizualnej fotografii Groza wojny, którą wykonał Nick Ut pod miejscowością Trảng Bàng omyłkowo zaatakowaną napalmem. Wyjątkowy charakter słynnego zdjęcia polega na tym, że mimo okoliczności skrajnie zawężających pole wyboru w zakresie momentu jego wykonania, perspektywy i kompozycji kadru, szczęśliwym trafem udało się zarejestrować na kliszy obraz nadzwyczaj wymowny i nośny znaczeniowo. Określeniu jego semantyki służą porównania z oryginalnym, nieprzyciętym kadrem, ze zdjęciem tej samej sytuacji, które Ut wykonał moment później, a przede wszystkim szczegółowa analiza struktury obrazu. Ukazuje ona istotne cechy charakterystyczne dla języka obrazów narracyjnych, konstytuujące ścisłą zależność semantyki od rygoru kompozycji jako syntaksy. Za ich sprawą zdjęcie zyskuje niezwykle wyrazisty charakter ikoniczny nie tylko w tym sensie, że stało się rodzajem „ikony” utrwalającej obraz konkretnego epizodu wojny w zbiorowej świadomości i historycznej pamięci, ale przede wszystkim ikoniczny w znaczeniu, które określiła koncepcja ikoniki Maxa Imdahla.
The essay brings an exhaustive analysis of the semantically productive features discernible in the visual structure of the photograph The Terror of War, taken by Nick Ut near the mistakenly napalm-bombed town of Trảng Bàng. The unique nature of the famous photograph lies in the fact that, despite circumstances that were extremely restrictive in terms of the timing, perspective and composition of the frame, by a sheer stroke of luck it proved possible to capture on film an image that is extremely meaningful and semantically loaded. The semantics of the image was determined by the author by comparing this image and the original frame with a photograph of the same situation taken by Ut a moment later, as well as, above all, through a detailed analysis of the image’s structure. This structure reveals the essential characteristics of the language of narrative images, which constitute the close dependence of semantics on the rigour of composition as syntax. Through them, the photograph acquires a highly expressive iconic character, not only in the sense that it has become a kind of an “icon” perpetuating the image of a specific event in collective consciousness and historical memory, but above all in the sense defined by Max Imdahl’s conception of the iconics.

Opis:
Multi-Criteria Group Decision Making (MCGDM) aims to find a unique agreement from a number of decision makers/users by evaluating the uncertainty in judgments. In this paper, we present a General Type-2 Fuzzy Logic based approach for MCGDM (GFLMCGDM). The proposed system aims to handle the high levels of uncertainties which exist due to the varying Decision Makers’ (DMs) judgments and the vagueness of the appraisal. In order to find the optimal parameters of the general type-2 fuzzy sets, we employed the Big Bang-Big Crunch (BB-BC) optimization. The aggregation operation in the proposed method aggregates the various DMs opinions which allow handling the disagreements of DMs’ opinions into a unique approval. We present results from an application for the selection of reading lighting level in an intelligent environment. We carried out various experiments in the intelligent apartment (iSpace) located at the University of Essex. We found that the proposed GFL-MCGDM effectively handle the uncertainties between the various decision makers which resulted in producing outputs which better agreed with the users’ decision compared to type 1 and interval type 2 fuzzy based systems.

Opis:
Mobile Mapping Systems (MMS) can be defined as moving platforms which integrates a set of imaging sensors and a position and orientation system (POS) for the collection of geo spatial information. In order to fully explore the potential accuracy of such systems and guarantee accurate multi-sensor integration, a careful system calibration must be carried out. System calibration involves individual sensor calibration as well as the estimation of the inter-sensor geometric relationship. This paper tackles a specific component of the system calibration process of a multi-camera MMS – the estimation of the relative orientation parameters among the cameras, i.e., the inter-camera geometric relationship (lever-arm offsets and boresight angles among the cameras). For that purpose, a novel single step procedure, which is easy to implement and not computationally intensive, will be introduced. The proposed method is implemented in such a way that it can also be used for the estimation of the mounting parameters among the cameras and the IMU body frame, in case of directly georeferenced systems. The performance of the proposed method is evaluated through experimental results using simulated data. A comparative analysis between the proposed single-step and the two-step, which makes use of the traditional bundle adjustment procedure, is demonstrated.

Opis:
The research applications of fuzzy logic have always been multidisciplinary in nature due to its ability in handling vagueness and imprecision. This paper presents an analytical study in the role of fuzzy logic in the area of metaheuristics using Web of Science (WoS) as the data source. In this case, 178 research papers are extracted from it in the time span of 1989-2016. This paper analyzes various aspects of a research publication in a scientometric manner. The top cited research papers, country wise contribution, topmost organizations, top research areas, top source titles, control terms and WoS categories are analyzed. Also, the top 3 fuzzy evolutionary algorithms are extracted and their top research papers are mentioned along with their topmost research domain. Since neuro fuzzy logic poses feasible options for solving numerous research problems, hence a section is also included by the authors to present an analytical study regarding research in it. Overall, this study helps in evaluating the recent research patterns in the field of fuzzy metaheuristics along with envisioning the future trends for the same. While on one hand this helps in providing a new path to the researchers who are beginners in this field as they can start exploring it through the analysis mentioned here, on the other hand it provides an insight to professional researchers too who can dig a little deeper in this field using knowledge from this study.

Opis:
This research adopted literature analysis methods to explain the principles and types of line illusion and, secondly, using Grasshopper software generated some fashion design samples with visual illusion element application. Then semantic analysis was applied to investigate audiences’ cognition, with the aim to improve the design. Lastly, Grasshopper software was used to generate new design patterns by changing the set of generated points through algorithm operation and dotted line interference to change the presented linear illusion forms and patterns. The results of this research show that with the support of parametric technology, the opportunities and space for creating line elements in clothing will be further expanded, enabling that real-time pattern or apparel design changes, and adjustments can be realized by parameter variable controlling. The research comprised a new attempt at combining linear visual illusion, fashion design and parametric design, showing the content and design case studies for relevant research in this area.

Opis:
A general form of the dynamics obtained as a limit of trajectories of singularly perturbed linear control systems is presented. The limit trajectories are described in terms of probability measure-valued maps. This allows to determine the extent to which the bang-bang principle for linear control systems is carried over to the singular limit.

Opis:
The proposed sintering process produce porosity and functional graded microstructure in the sinterd titanium powders. Titanium powders with different micro sizes were sintered at the proposed temperature region at 1200 and 1300°C for 2h. The apatite-forming on the graded microstructure is observed by immersion test in Hanks balanced salt soluion at 37°C. Sintering condition of titanium powders is estimated by thermogravitmetry-differential thermal analysis (TG-DTA). The synthersied surface structures and apatite-forming ability were characterized by a field emission scanning electron microscopy (FE-SEM) observation and energy dispersive X-ray spectroscopy (EDS) analysis. As results, these graded microstructure of sintered porous titanium powders reveals apatite-forming ability as osseointegration by calcification in Hanks balanced salt soluion(HBSS) at 37°C.

Opis:
Second order optimality conditions have been derived in the literature in two different forms. Osmolovskii (1988a, 1995, 2000, 2004) obtained second order necessary and sufficient conditions requiring that, a certain quadratic form be positive (semi)-definite on a critical cone. Agrachev, Stefani, Zezza (2002) first, reduced the bang-bang control problem to finite-dimensional optimization and then show that well-known sufficient optimality conditions for this optimization problem supplemented by the strict bang-bang property furnish sufficient conditions for the bang-bang control problem. In this paper, we establish the equivalence of both forms of sufficient conditions and give explicit relations between corresponding Lagrange multipliers and elements of critical cones. Part 1 summarizes the main results while detailed proofs will be given in Part 2.
