The main goal of this article is to determine a comprehensive and well applicable model architecture, which is adequate to estimate the system level advantages with regard to automated transportation and which is appropriate to determine possible costs and losses with regard to the approach of such transport modes. In the study the Budapest Transportation Model is applied. Taking autonomous vehicle penetration into account as an external variable, in the analysis a constant growth is assumed in the penetration of automated vehicles. This article has taken the most relevant factors of transportation network into account with regard to automated cars. It is also important to mention that the paper presents the most important modelling phases, where automated cars can be taken into account during the macroscopic modelling process. In the first step of the process during the network definition phase it is possible to consider the effect of automated vehicles on the transport system (e.g. separated routes). The next phase where the effect of automated vehicles should be taken into consideration is the mode choice step (e.g. different demand segments). And finally traffic assignment step, where the effect of automated vehicles can be represented. The easiest way for this is the modification of passenger car units through the parameter of assigned traffic per capacity ratio.

Definition Phase

This article frames the requirements definition phase of systems design as a problem of knowledge transfer and learning between two communities of practice: IS designers and system users. The theoretical basis for the proposed approach is Wenger’s (1998) framework for social learning, which involves three dimensions: alignment, imagination, and engagement. The article treats the requirements definition task in systems design as a set of activities involving mutual learning and knowledge transfer between two communities of practice (CoP) along these three dimensions. In taking this approach, the article maps the results of past research on the systems design process onto this CoP framework and illustrates that the proposed framework encompasses the same activities used by traditional methods of requirements definition. However, this approach focuses attention on the learning that must take place between the two CoPs and thereby helps resolve some of the inherent shortcomings of prior efforts and approaches. The framework provides both a more encompassing conceptual lens for research on improving the requirements definition task and practical guidance for managers who are charged with a systems design project.

Algebra structure is a branch of abstract mathematics, which is generally more difficult than the other more concrete branches of mathematics. The on going problems in the subject of  Algebra structure is the students do not understand about the concept of algebra structures, so that students have difficulty in using theories or theorems in evidence. In addition, another cause is the algebra structure of the teaching material is too abstract, so that students are less motivated to read supporting books and it causes low student activities. There may be one way to improve the motivation, activity and learning outcomes of students like using the Student Worksheet (MFIs). The purpose of this research was to develop an effective MFI Guided on the subject of Algebraic Structures in STKIP PGRI West Sumatra. This type of research was a developmental research. This research used 4-D models composed of 4 phases: definition phase (define), the design (design), development (develop) and spread (disseminate). In the deployment phase of the trial is limited to classes only. Effectiveness was analyzed through the observation student activity during lectures, student motivation by providing motivation questionnaire after using Guided MFI and student outcomes. Data analysis was analyzed descriptively with the results after using Guided MFIs in the subject of Algebra structure can enhance the activity, motivation and learning outcomes of students. The level of student mastery learning outcomes is more than 68%. It means that MFI Guided is effective in improving the student learning outcomes. The results show that the MFIs Guided on the subject of Algebra Structure developed has been effectively used as a teaching material for students.

Commuter airlines have generally demonstrated excellent growth in recent years. This growth has been accomplished mainly with aircraft that have evolved from larger general aviation aircraft or specially designed utility aircraft. None reflect a configuration optimized for the current type of passenger service early in the vehicle definition phase. This paper investigates the impact of configuration considerations, mission requirements, and performance constraints on conceptual commuter aircraft designs. Emphasis is placed on direct comparisons between turbofan and turboprop powered aircraft in the 10–30 passenger class. The analysis is accomplished using a computerized aircraft synthesis model that simulates the aircraft design and mission. The resulting conceptual aircraft are similar in size and performance regardless of engine type but the turboprop offers more mission flexibility.

The core theme of the previous chapters is that a methodical and structured approach to PT is rather necessary right from the early phases of the development cycle. This will ensure predictability and controllability of application performance in practice. The preparatory activities associated with PT (Figure 4.1) are of great importance and are distributed over the life cycle phases of requirement elicitation and analysis, High Level Design (HLD), Detail Level Design (DLD), and several sets of system builds. These activities help define and provide continuity between the high level requirements for application performance, strategies for testing, a framework for designing the tests (see Barber, 2004), and artifacts used to plan and carry out tests. This chapter contains a detailed consideration of the definition phase while Chapters 5 and 6 highlight issues related to the design and build phases associated with the preparatory activities as shown in Figure 4.1.
