The quantification of human movements is very hard because of the sparsity of traditional data and the labour intensive of the data collecting process. Recently, much spatial-temporal data give us an opportunity to observe human movement. This research investigates the relationship of city-wide human movements inferring from two types of spatial-temporal data at traffic analysis zone (TAZ) level. The first type of human movement is inferred from long-time smart card transaction data recording the boarding actions. The second type of human movement is extracted from citywide time sequenced mobile phone data with 30 minutes interval. Travel volume, travel distance and travel time are used to measure aggregated human movements in the city. To further examine the relationship between the two types of inferred movements, the linear correlation analysis is conducted on the hourly travel volume. The obtained results show that human movements inferred from smart card data and mobile phone data have a correlation of 0.635. However, there are still some non-ignorable differences in some special areas. This research not only reveals the citywide spatial-temporal human dynamic but also benefits the understanding of the reliability of the inference of human movements with big spatial-temporal data.

The characteristics of flocs aggregated in flocculation have been paid more and more attention for a long time. In this paper, a new classification and analyses method dealing with the flocs is developed. The flocs formed after flocculation is divided into four kinds, including the left primary particles, linear flocs with all component particles in a line, planar flocs with all component particles on a plane and volumetric flocs with all component particles in a three-dimensional space. By analyzing the formation approaches of different kind of flocs regardless of the floc breakage, the number of every kind of floc is analyzed to be related with the suspension concentration mathematically. After comparing the different items in the models describing the relationship of floc number and concentration, a series of simplified expressions are presented. Lastly, a mathematical equation relating the measurable suspension viscosity with the numbers of different flocs is obtained.

The work reported in this article is concerned with the relationship of the user to his mobile phone, especially with the habit of checking the mobile phone for missed events. We present two qualitative studies that have been conducted with mobile phones, symbolizing their status through life-like movements - breath and pulse. It was to be determined whether a continuous, rythmic and life-like signal would be eligible to ambiently express the phone’s state. The results of the studies were mixed, as some users were simply annoyed by the permanent actuation, while others appreciated the functionality. The response times to occured events seem to be appropriate for an ambient display. The studies raised further questions, regarding the psychological and physiological consequences of such technology.

Space is the main material with which the architect works. The space organized by the means of architecture is an art environment for the life of society. With many aspects of the organization of space, which are studied in the literature, the problem of their assembly and integration remains unsolved. The paper proposes a method of assembling spatial representations in architecture-the correlation of the spatial lattice and the factors of its form-formation, considered in the system, i.e. together. The approach is that in a broad overview of the world architecture, both in its theory and in practice, from historical to modern, examples of modification of spatial grids under the influence of one or a group of dominant factors are revealed. As a result, provisions on the relationship of the geometry of spatial grids with the following factors have been revealed: publicity and privacy; architectonics, the influence of the lattice on the differentiation of the streams of human movement; the architecture’s ability to carry a message; navigation properties, evaluation of connectivity and centrality of places in the spatial lattice; evaluation of the quality of the composition through the identification of ways of order and randomness in the elements of the spatial lattice. The results of the work can be used both for theoretical understanding of the architectural space in the study and design of architecture, and in architectural education.

This article highlights different ways of metaphorical use in language and shows its potential in attracting the readers' attention. Language as a biological being lives its own life witnessing never-ending changes: falling outs and newly built elements. We enrich our language not only by new elements but also by new styles and reusing of existing sources. One of these ways which makes language more alive and active is metaphor. Metaphor nowadays is found in all the fields of life, education, medicine, policy and everyday life. Metaphor, in fact, reflects the relationship of language to culture and the world of ideas. Language, on the one hand, is a repository of culture; the traditions, proverbs, and knowledge of our ancestors. On the other hand, language is the mirror of the world of ideas. People reflect their new ideas in using language in new ways, even such devices as paintings and riddles. Metaphor has many shapes and is found in spoken and written language, graphics, cartoon or caricature, riddles, jokes and paintings to express novel shades of meanings, e.g., metaphor in newspaper photos, magazines or even in advertisements attracts the attention of readers and are memorized for a long time. Metaphoric use is also a way of enjoying the readers. It is used for both real and logical aims such as; warnings, advises, or invitations ...etc

This study is to find out the relationship of characters to illustrations in a collection of 9short stories from NadiraKarya Leila S. Chudori. In the collection, there are four short stories that contain illustrations of the main characters namely "Melukis Langit”, "Tasbih", "Sebilah Pisau", and "At Pedder Bay". The method used in this research is descriptive qualitative method by using Charles Sanders Pierce's Semiotic Theory which includes sign and object. The study of characterization or characterization is done in two methods namely direct (telling) and indirect (showing). The results of  this study indicate that out of the 4 short stories analyzed only 3 short stories that have character relationships with illustrations, namely the short story "Melukis Langit", "Tasbih" and "Sebilah Pisau". Short story of "Melukis Langit" depicts Nadira's character who is strong against her father's behavior since the death of his mother. The short story illustration shows Nadira crying in the bathroom to vent her sadness. Short story "Tasbih" describes Mr. X with a mysterious character illustrated by showing Mr. X's face full of mystery while the short story "Sebilah Pisau" tells Kris who is Nadira's secret admirer. Kris's character is displayed with illustrations illustrating the event when Nadira was surprised to see Kris's table filled with Nadira's picture. Short story "At Pedder Bay" tells Nadira's old friend Marc who is also an admirer of Nadira for a long time. The main character, Marc in this short story is not illustrated in the illustration. The short story shows a background, namely the lake and the figure of the woman sitting pensively.

The article, for the first time, exami­nes the work of the master of the 18th century Jean-Honoré Fragonard (1732—1806) within the context of the theatre culture of that time. Being a student of François Boucher (1703—1770), who was working as a theater decorator for a long time, Fra­gonard from his youth had the opportunity to join the world of theater. The painter’s passion for the stage greatly influenced the thema­tic and figu­rative composition of his works. Early histo­rical pain­tings of Fragonard, such as “Jeroboam Sacrifi­cing to Idols” (1752, School of Fine Arts, Paris), were crea­ted under the influence of Baroque thea­ter and decorative art and opera productions. Undoubtedly, Fragonard’s familiarity with theatre was promoted by his long stay in Italy, where the famous families of theater decorators Bibiena and Galliari was wor­king at that time. The article pays special attention to the process of planning and execution of the painting “The High Priest Coresus Sacrificing Himself to Save Callirhoe” (1765, Louvre), made not without regard to the opera “Callirhoe”, popular in Paris in the 18th century. It was theater that inspired the master to create his famous costume series of “Fantasy Portraits”, one of which depicted Marie-Madeleine Guimard (1743—1816), who not only had posed for the artist, but also ordered him to design her own mansion conceived as a temple of Terpsichore, the Muse of dance. In addition, Fragonard was the author of several panoramic genre paintings conveying the atmosphere of the then popular street theater. Works of this brilliant master exem­plify the relationship of arts that determined the nature of the cultural environment of that era and requires constant attention from modern researchers.

The increasing availability of mobile phone data has attracted the attention of several researchers interested in studying our collective behaviour. Our interactions with the phone network can take several forms, from SMS messages to phone calls and data usage. Typically, mobile phone data are released to researchers in the form of call detail records , which contain records of different types of interactions, and can be used to analyse various aspects of our behaviour. However, the inherently behavioural nature of these interactions may result in differences between how we make phone calls and receive text messages. Studies which rely on data derived from these interactions, therefore, need to carefully consider these differences. Here, we aim to investigate differences and limitations of different types of mobile phone interactions data by analysing a large mobile phone dataset. We study the relationship between different types of interactions and show how it changes over time. We anticipate our findings to be of interest to all researchers working in the area of computational social science.

Unsteady viscous flows and Stokes's first problem are examined. Three problems are considered: unsteady Couette flow, unsteady Poiseuille flow, and unsteady boundary layer flow. The relationship between these three fundamental unsteady flows and Stokes' first problem is illustrated. Scaling principles are used to deduce the short time and long time characteristics of these three problems. Asymptotic analysis is used to obtain exact short and long time characteristics and to show the relationship of each problem to Stokes's first problem for short times. Finally, compact robust models are developed for all values of time using the Churchill-Usagi asymptotic correlation method to combine the short and long time characteristics.
