Innovation has two key levers: the capacity to consider and predict consumer desires, on the one hand, and the building of collaboration between the economic environment, metropolitan players, and knowledge and development actors, somewhere else. Innovation is not just technical, and it disrupts traditions and station partners' aspirations and perceptions: planners, administrators, consumers or clients, and causes a change in locations and uses. The expansion of the rail network in Iraq is renewing station sites, especially in Iraq, which, at the cost of medium-sized cities between these cities, prefer the logic of productivity-focused on express services between major cities. On the field, this alternative translates into two styles of stations that are central base stations for significant towns, and medium- and small-town terminals—establishing stations benefits from an interconnected phase of all spatial organization types. Suppose we research the decision phase that led to the establishment of train stations in Iraq. In that case, we find that this option and construction strategies are a mixture of component elements according to the area details served and actors' strategies. Most chosen sites result from deep relationships between global, regional, and local reasoning.

This work attempts to enhance the performances of the stroke ratio and/or thrust saving of the conventional and Fanuc five-point double-toggle mould clamping mechanisms, at the cost of increasing the offset and varying the cross-head height and loosening the initial transmission performance within an acceptable extent, on condition that the overall horizontal length cannot exceed the one of the original design in the work of Lin and Hsiao [1]. In addition, to show the effect of the initial transmission performance and the effect of the combination of the offset and the crosshead height individually, the present and previous designs in the work of Lin and Hsiao without loosening the initial transmission performance are also presented. The parameter study in the work of Lin and Hsiao is extended to synthesize the conventional and Fanuc linkages and to find the optimal dimensions in the programming discrete domain. The kinematic stick diagrams in the open and closed positions for the original and present designs are shown, which may see some features of the profiles of the toggle linkages with the larger stroke ratio and/or thrust saving and the difference between the two designs.

Flood is one of the most important natural disasters that cause the casualties and losses every year. Today, the massive growth of the population, the leveling of the land and the occupation of rivers and waterway s, along with the climatic and physiographic factors in big cities, have caused the urban flood spread. Bojnourd City has a high degree of vulnerability to natural hazards due to its geographical location in the Kopet Dag and Aladagh mountains, and the presence of rivers and waterway s inside it, on the one hand, and placing on the faults on the other hand.In this research, a descriptive-analytical method and the aerial maps have been used to collect the information.The results of the research indicated that Bojnord City is highly expected to flood in terms of the probability of flood-related vulnerability.

Regardless to the facts that English is being taught to Indonesian students starting from early age, many Indonesian thrive in learning English. They find it quite troublesome for some to acquire the language especially to the level of communicative competence. Although Krashen (1982:10) states that “language acquirers are not usually aware of the fact that they are acquiring language, but are only aware of the fact that they are using the language for communication”, second language acquisition has several obstacles for learners to face and yet the successfulness of mastering the language never surmounts to the one of the native speakers. Learners have never been able to acquire the language as any native speakers do. Mistakes are made and inter-language is unavoidable. McNeili in Ellis (1985, p. 44) mentions that “the mentalist views of L1 acquisition hypothesizes the process of acquisition consists of hypothesis-testing, by which means the grammar of the learner’s mother tongue is related to the principles of the ‘universal grammar’.” Thus this study intends to find out whether the students go through the phase of interlanguage in their attempt to acquire second language and whether their interlanguage forms similar system as postulated by linguists (Krashen).


The article is devoted to reengineering of technological processes - a method of their qualitative transformation on an innovative basis, which in turn assumes the availability of tools that make it possible to establish the economic efficiency and technical capability of such transformations of construction production, to identify the effect of their implementation. In this regard, the problem of forming a parametric model of reengineering of construction technological processes, which involves four enlarged groups of indicators that reflect the quantitative and qualitative characteristics of the processes: materials used, working time, machine time, spatial organization, is considered. It is established that parameters can have either an absolute (physical, cost) or relative (point, percentage) expression and also make their own decomposition. The practical significance of the provisions given in the article is determined by the development of methods of technical rationing, which leads to a reduction in the cost and duration of construction.

Abstract The present paper focuses on spatial management regulations in order to carry out investment in the field of airport facilities. The construction, upgrades, and maintenance of airports falls within the area of responsibility of local authorities. This task poses a great challenge in terms of organisation and finances. On the one hand, an active airport is a municipal landmark and drives local economic, social and cultural development, and on the other, the scale of investment often exceeds the capabilities of local authorities. The immediate environment of the airport determines its final use and prosperity. The objective of the paper is to review legislation that affects airports and the surrounding communities. The process of urban planning in Lodz and surrounding areas will be presented as a background to the problem of land use management in the vicinity of the airport. This paper seeks to address the following questions: if and how airports have affected urban planning in Lodz, does the land use around the airport prevent the development of Lodz Airport, and how has the situation changed over the time? It can be assumed that as a result of lack of experience, land resources and size of investments on one hand and legislative dissonance and peculiar practices on the other, aviation infrastructure in Lodz is designed to meet temporary needs and is characterised by achieving short-term goals. Cyclical problems are solved in an intermittent manner and involve all the municipal resources, so there’s little left to secure long-term investments.

Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implemented by one of the companies engaged in telecommunications. In its implementation, each project including Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in the contract. Project scheduling is an important role in predicting both the cost and time in a project. Every project should be able to complete the project before or just in the time specified in the contract. Delay in a project can be anticipated by accelerating the duration of completion by using the crashing method with the application of linear programming. Linear programming will help iteration in the calculation of crashing because if linear programming not used, iteration will be repeated. The objective function in this scheduling is to minimize the cost. This study aims to find a trade-off between the costs and the minimum time expected to complete this project. The acceleration of the duration of this study was carried out using the addition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and 1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp. 52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour of overtime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect the entire project because there are 33 different locations worked on Shift to The Front II and if all these locations can be accelerated then the duration of completion of the entire project will be effective
