The paper presents the results of the study of the techniques of joining the parts of traditional shirts. The analysis of museum pieces presents various techniques for combining landmarks with a functional and aesthetic role. In traditional holiday women’s shirts, the joining of of parts on the lines arranged in the accessible visual perception area techniques of joining by keys of different complexity, integrated solutions of edge processing elements by crocheting and joining techniques by keys („cheițe”) were used. The joining lines of the parts arranged in areas with low visibility show applications of simple joining techniques such as stitches before the needle, after the needle, the processing of the edges of the parts with scalloped points. Traditional men’s holiday shirts used the joining of keys in some models, but shirts were also made in which the application of the techniques of joining by keys is missing. In the usual traditional shirts, the techniques of joining by keys are very rare. The terminal lines of the parts of the holiday shirts, as well, present various processing and decoration techniques applying the processing with «brezărău», the processing with crocheted lace.

Pylyshyn's argument is very similar to one made in the 1960s to the effect that vision may be influenced by spatial selective attention being directed to distinctive stimulus features, but not by mental set for meaning or membership in an ill-defined category. More recent work points to a special role for spatial attention in determining the contents of perception.

Abstract Vision and language are two fundamental capabilities of human intelligence. Humans routinely perform tasks through the interactions between vision and language, supporting the uniquely human capacity to talk about what they see or hallucinate a picture on a natural-language description. The valid question of how language interacts with vision motivates us researchers to expand the horizons of computer vision area. In particular, “vision to language” is probably one of the most popular topics in the past 5 years, with a significant growth in both volume of publications and extensive applications, e.g. captioning, visual question answering, visual dialog, language navigation, etc. Such tasks boost visual perception with more comprehensive understanding and diverse linguistic representations. Going beyond the progresses made in “vision to language,” language can also contribute to vision understanding and offer new possibilities of visual content creation, i.e. “language to vision.” The process performs as a prism through which to create visual content conditioning on the language inputs. This paper reviews the recent advances along these two dimensions: “vision to language” and “language to vision.” More concretely, the former mainly focuses on the development of image/video captioning, as well as typical encoder–decoder structures and benchmarks, while the latter summarizes the technologies of visual content creation. The real-world deployment or services of vision and language are elaborated as well.

The subconscious includes all mental events that stay out of conscious perception and have no potential to access to the level of conscious. In our present day, the conscious is one of the objects where the advertisers often use it to make hidden inducements in order to influence the behaviors of the consumers and where the desire to buy a product is created, placed in it to best market and publicize their own trademarks and products. When the consumer wants to buy a product, it is necessary that the product for which advertisement is made in the mind emerge. And, this makes us question the necessity of the visual perception management in the human brain. In daily life, thousands of information, pictures and sounds go to the memory on a daily basis, and the human brain recalls them if only they are necessary. For this reason, the advertisers develop their products with such kind of methods which could be recorded in their clients’ memory for a long time.Eighty percent of the perception is structured by the eyesight. The expert psychologists work together with the art directors within the companies where the hidden messages are produced, in order to place in the pictures such images which are to attract attention of the subconscious. Such images have certain qualities which trigger and actuate the visual perception. E.g: placing into the background the green color in order to make a product look more reddish.This study includes the way of functioning of the visual perception in the advertisements together with the examples, and researches whether the attempts to actuate and induce the human feelings and motives could in fact control the behaviors and thoughts, and whether they are right ethically.Keywords: visual perception management, advertisements, subconscious, tachistoscope, poetzle effect.

It is assumed that when a pilot flies according to visual flight reference, control adjustments are made in order to control visual perception. If so, the optical variables and invariants produced by the pilot can serve as dependent variables in research on information used in guiding flight. Visual flight simulators provide an ideal experimental environment for exploring the optical approach to the study of pilots' perception-action cycles.

Standard Disc

Twenty subjects were shown a film containing 54 presentations of a moving standard disc followed immediately by one of six well-known target objects moving at the identical velocity. The subjects were asked to judge the speed of the target in relation to the standard. Judgments were made in arbitrary numbers from 0-50 to enable calculation of error magnitude as well as direction. It was hypothesized that objects which are known to move fast would be overestimated in relation to the standard while objects known to move slow would be underestimated. The results did not fully support the hypotheses. However, they did point up a need for research into the possible existence of differential modes of perception mediated by changes in objective speed of the target.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Ultramicrotomy produces plastic deformation in the surfaces of microtomed TEM specimens which can not generally be observed unless special preparations are made. In this study, a typical biological composite of tissue (infundibular thoracic attachment) infiltrated in the normal manner with an embedding epoxy resin (Epon 812 in a 60/40 mixture) was microtomed with glass and diamond knives, both with 45 degree body angle. Sectioning was done in Portor Blum Mt-2 and Mt-1 microtomes. Sections were collected on formvar coated grids so that both the top side and the bottom side of the sections could be examined. Sections were then placed in a vacuum evaporator and self-shadowed with carbon. Some were chromium shadowed at a 30 degree angle. The sections were then examined in a Phillips 300 TEM at 60kv.Carbon coating (C) or carbon coating with chrom shadowing (C-Ch) makes in effect, single stage replicas of the surfaces of the sections and thus allows the damage in the surfaces to be observable in the TEM. Figure 1 (see key to figures) shows the bottom side of a diamond knife section, carbon self-shadowed and chrom shadowed perpendicular to the cutting direction. Very fine knife marks and surface damage can be observed.

Iron is believed to play an important role in the pathogenesis of ischemic injury. However, the sources of intracellular iron in myocytes are not yet defined. In this study we have attempted to localize iron at various cellular sites of the cardiac tissue with the ferrocyanide technique.Rat hearts were excised under ether anesthesia. They were fixed with coronary perfusion with 3% buffered glutaraldehyde made in 0.1 M cacodylate buffer pH 7.3. Sections, 60 μm in thickness, were cut on a vibratome and were incubated in the medium containing 500 mg of potassium ferrocyanide in 49.5 ml H2O and 0.5 ml concentrated HC1 for 30 minutes at room temperature. Following rinses in the buffer, tissues were dehydrated in ethanol and embedded in Spurr medium.The examination of thin sections revealed intense staining or reaction product in peroxisomes (Fig. 1).

The advances in recent years in the microanalytical capabilities of conventional TEM's fitted with probe forming lenses allow much more detailed investigations to be made of the microstructures of complex alloys, such as ferritic steels, than have been possible previously. In particular, the identification of individual precipitate particles with dimensions of a few tens of nanometers in alloys containing high densities of several chemically and crystallographically different precipitate types is feasible. The aim of the investigation described in this paper was to establish a method which allowed individual particle identification to be made in a few seconds so that large numbers of particles could be examined in a few hours.A Philips EM400 microscope, fitted with the scanning transmission (STEM) objective lens pole-pieces and an EDAX energy dispersive X-ray analyser, was used at 120 kV with a thermal W hairpin filament. The precipitates examined were extracted using a standard C replica technique from specimens of a 2¼Cr-lMo ferritic steel in a quenched and tempered condition.

Zirconia (ZrO2) is often added to ceramic compacts to increase their toughness. The mechanisms by which this toughness increase occurs are generally accepted to be those of transformation toughening and microcracking. The mechanism of transformation toughening is based on the presence of metastable tetragonal ZrO2 which transforms to the monoclinic allotrope when stressed by a propagating crack. The decrease in volume which accompanies this transformation effectively relieves the applied stress at the crack tip and toughens the material; microcrack toughening arises from the deflection of a propagating crack around sharply angular inclusions.These mechanisms, however, do not explain the toughness increases associated with the class of composites investigated here. Analytical electron microscopy (AEM) has been used to determine whether solid solution effects could be the cause of this increased toughness. Specimens of a mullite (3Al2O3·2SiO2) + 15 vol. % ZrO2 were prepared by the usual technique of mechanical thinning followed by ion beam milling. All observations were made in a Philips EM400 TEM/STEM microscope fitted with EDXS and EELS spectrometers.
