Studies about the vegetative development of Legume trees are relatively rare. In order to infer about the evolution of different development patterns a study of taxonomically related species is requiered. We analyzed three species of Acacia (A . collinsii, A. cedilloi and A. dolichoslachya) which according to preliminary observations show branching patterns as defined in the architectural model of Troll or Champagnat in order to answer the question which is the evolutionary relation between these models. We describe the development pattern of these species and found that a combination of architectural models is needed to do so. We found that mixed plagiotropic axes in A. collinsii are relayed by orthotropic axes during development and open a discussion to the evolutionary origen of the mixed axis.

Optimization of a prediction (forecasting) is very important to do so that the predicted results obtained to be better and quality. In this study, the authors optimize previous research that has been done by the author using backpropagation algorithm. The optimization process will use Conjugate Gradient Beale-Powell Restarts. Data to be predicted is Consumer Price Index data based on health group from Medan Central Bureau of Statistics from 2014 until 2016. Previous research using 8 architectural models, namely: 12-5-1, 12-26-1, 12-29 -1, 12-35-1, 12-40-1, 12-60-1, 12-70-1 and 12-75-1 with best architectural models 12-70-1 with an accuracy of 92%. In contrast to previous research concentrating on finding accuracy using backpropagation, this study will optimize the backpropagation with Conjugate Gradient Beale-Powell Restart, which not only focuses on accuracy but also the convergence of the two algorithms and the translation of predicted results, which is not done in a previous study. This research will use the same architectural model as the previous research and will get the result with the accuracy of 92% with the best architectural model that is 12-70-1 (same as previous research). Thus, this model is good enough for prediction even with different algorithms, since the accuracy of converging backpropagation with Conjugate Gradient Beale-Powell Restarts.

Interface Standardization

Virtual Environments are complex systems in that they involve the crucial concept of sharing. Users can share knowledge of each other’s current activities, environments, and actions. In this chapter, the authors discuss about interaction interoperability, intended to mean the ability of two or more users to cooperate despite the heterogeneity of their interfaces. To allow such interoperability, formal methods to formalize the knowledge and middleware solutions for sharing that knowledge are required. After introducing the state-of-the-art solutions and the open issues in the field, the authors describe a system for providing interaction interoperability among multi-user interfaces. Rather than focusing on the de-coupling of input devices from interaction techniques and from interaction tasks, this chapter suggests integrating interactive systems at higher level through an interface standardization. To achieve this aim, the authors propose: i) an architectural model able to handle differences in input devices and interaction tasks; ii) an agent-based middleware that provides basic components to integrate heterogeneous user interfaces. The chapter also presents a case study in which an agent-based middleware is used to support developers in the interconnection of monolithic applications.

Model Driven Approach

Model-driven development is recognized as one of the most promising approaches in software engineering. Recent research in the area highlights the importance of using an explicit architectural model in this context. Since service-oriented architectures have also demonstrated to be adequate to overcome current software needs, the idea of using the model-driven approach to generate service-oriented architectural models has successfully flourished in the last years. However, the emphasis on the Service-Oriented Computing (SOC) paradigm has led to the design of architectures lacking some desirable features. Knowing the benefits provided by architectural styles, we have found that their use can help us to overcome those needs. Our goal is to obtain a service-oriented model which satisfies the requirements of the concrete architecture and complies with the constraints and vocabulary defined for a specific architectural style. To achieve this, here, we propose to use a weaving model which merges the concrete architectural model with a model of the architectural style of choice.

Abstract. Loess is a porous, weakly cemented, and unsaturated Quaternary sediment deposited in arid and semi-arid regions by the wind. It is widely and thickly distributed in China, making the Loess Plateau the largest bulk accumulation of loess on the Earth. However, the fragile geoenvironment in the loess areas of China causes frequent and various geohazards, among which, the Cracking-sliding (Beng-hua) is a typical failure mode because it causes the largest number of casualties each year. This study investigates the development pattern and main influencing factors of cracking–sliding failure to help in effectively preventing its occurrence and reducing losses. The following conclusions are derived: (1) cracking–sliding failures are prone to occur in rectilinear slopes, convex slopes, slopes with gradients greater than 60°, slopes with heights of 5 m to 40 m, and sunward slopes with aspects of 180° to 270°; (2) cracking–sliding failures occur mostly from 9 p.m. to 4 a.m. the next day, and concentrates in the rainy season (July to September) and freeze-thaw season (March to May); and (3) the more intense the human activities in the region, the greater the possibility of cracking–sliding failures.

Architectural Characteristics

Sylleptic branching occurred on the current (1983) height-growth increment in 44% of Larix laricina (Du Roi) K. Koch (tamarack) saplings sampled from a natural population near Fredericton, N.B. Although variable, the occurrence and amount of syllepsis tended to increase with parental shoot length. Sylleptic shoots were generally located on the proximal halves of parental shoots. In most cases, the proximally and distally situated sylleptic shoots were somewhat shorter than those in between. The lengths of terminal shoots arising from sylleptic shoots were significantly correlated with parental shoot length, current tree leader length, and location of the branch on its parental shoot. The lengths and elevation angles of terminal extensions from sylleptic shoots tended to be greater than those from nonsylleptic (proleptic) lateral long shoots borne in the same region of the height-growth increment. Architectural characteristics of the extensions resembled those of the more distal proleptic shoots, which develop into major branches. Thus, an additional complement of major lateral branches appeared to be developing where syllepsis occurred. Quantitative relationships depicting sylleptic branching patterns were incorporated into a previous architectural model and simulations of crown architecture which included syllepsis were obtained.

Root Buds

The growth patterns of Shepherdia canadensis and S. argentea from seedling stage to adult thicket have been analyzed and compared. In S. canadensis, the seedling axis, originally erect, showed a tendency for early bending towards the horizontal, followed by vertical reorientation of the tip. This was coupled with the basitonic expansion of lateral buds. In contrast, the seedling axis of S. argentea remained erect and branching was predominately acrotonic. As plants of S. canadensis matured, successive branches repeated the seedling pattern, reorienting downward with the tip compensating to remain erect. Basal buds expanded to fill the gap in the canopy and these in turn reoriented downward, repeating the cycle and forming a thicket with the youngest shoots in the centre. Rooting of the horizontal axes was observed and in some cases new thickets could be inititated in this way. In S. argentea, however, shoots remained erect and thicket formation occurred by the expansion of ramets from root buds at the periphery of the thicket. The shoots at the centre were thus the oldest. These features, together with information on branching patterns previously reported, have been used to construct constrasting architectural models for the two species. Key words: Elaeagnaceae, Shepherdia, Buffaloberry, architecture, morphology, development.

The topic of this study is the textual meaning in recount texts written by the fourth semester students of English Department Universitas Negeri Semarang in the academic year 2018/2019. This study is conducted since there are still limited research that is conducted in Indonesia which analyses the problems of thematic development because most of Indonesian researchers are only analyses the thematic structure and thematic development pattern. This study aimed to figure out the thematic structure, thematic development pattern, and the problems of thematic development in students’ recount texts. The text analysis of qualitative method was employed to enhance the results. The result of the thematic structures showed that the unmarked topical Theme was frequently used than the marked one in terms of topical Theme, the conjunctions became the mostly used element in textual Theme, and the modal adjuncts became the frequently used constituent in interpersonal Theme. In the case of thematic development patterns, the Theme re-iteration (constant Theme pattern) became the mostly used pattern since the function is to keep the text focused. It has been found that there were three problems of thematic development in students’ recount texts: (1) the problem of the brand-new Theme, (2) the problem of double Rheme, and (3) the problem of empty Rheme. The results of this study indicate that the students belong to beginner (inexperienced) writer.
