Truck platooning involves a small convoy of freight vehicles using electronic coupling as an application in automated driving technology, and it is expected to represent a major solution for improving efficiency in truck transportation in the near future. Recently, there have been several trials regarding truck platooning with major truck manufacturers and logistics companies on public roads in the United States, European countries and Japan. There is a need to locate a facility for the formation of truck platooning to realize the unmanned operation of trucks following in a platoon. In this study, we introduce the current status of truck platooning in Japan and present the optimal location model for truck platooning using the continuous approximation model with a numerical experiment, considering the case in Japan. We derived the optimal locational strategy for the combination of the long-haul ratio and the cost factor of platooning. With parameters estimated for several scenarios for the deployment of truck platooning in Japan, the numerical results show that the optimal locational strategy for a platoon of manned vehicles and a platoon with unmanned following vehicles is the edge of the local region, and that for a platoon of fully automated vehicles is the center of the region.

AbstractMost cities in the United States rely on zoning to address important planning-related issues within their jurisdictions. Planners often use GIS tools to analyze these issues in a spatial context. ESRI’s ArcGIS Urban software seeks to provide the planning profession with a GIS-based solution for various challenges, including zoning’s impacts on the built environment and housing capacity.This research explores the use of ArcGIS Urban for assessing the existing zoning and comprehensive plans in meeting the projected residential growth in the near future using the City of Arlington, Texas as a case study. The exploration provides examples and lessons for how ArcGIS Urban might be used by planners to accomplish their tasks and highlights the capabilities and limitations of ArcGIS Urban in its current stand. The paper is concluded with some suggestions for future studies.

Monotonically Decrease

Neighborhood rough sets (NRS) are the extended model of the classical rough sets. The NRS describe the target concept by upper and lower neighborhood approximation boundaries. However, the method of approximately describing the uncertain target concept with existed neighborhood information granules is not given. To solve this problem, the cost-sensitive approximation model of the NRS is proposed in this paper, and its related properties are analyzed. To obtain the optimal approximation granular layer, the cost-sensitive progressive mechanism is proposed by considering user requirements. The case study shows that the reasonable granular layer and its approximation can be obtained under certain constraints, which is suitable for cost-sensitive application scenarios. The experimental results show that the advantage of the proposed approximation model, moreover, the decision cost of the NRS approximation model will monotonically decrease with granularity being finer.

Significant Regional Difference

In order to develop realistic water resources strategy, we initially analyze the situation of water resources in the United States which present a significant regional difference. Then on the basis of previous studies, we propose the cost formulas of water storage, movement and desalinization. By analyzing the practical application, along with pros and cons of the above three solutions accordingly, we consider that a comprehensive utilization of these measures will be the best water strategy for America to solve the water shortage problem. Later we apply the conclusion to a case study of Southern California, we propose an optimization model which aims to minimize the total cost of the water strategy, and then use Lingo to solve the problem. Results show that 5.946 billion cubic meters of water by transferring is the best way to make up for the water use gap in 2025 and the total cost is 2.94 billion dollars. Finally, we summarize the strengths and weaknesses of our paper. What needs to be emphasized is that our model can also be adapted into the analysis of other states, which shows great flexibility.

The Cost

Recent studies on textbook costs in the United States have indicated that there is a direct relationship between textbook costs and student success. With textbook costs increasing at a rate higher than the cost of living, many students have cited the textbook cost as an extremely important factor when obtaining (or not obtaining) a textbook. Open educational resources (OER) are tools that educators can use to supplement or build a course. OER are free for anyone to reuse, revise, remix, and redistribute and are a low-cost, tailored solution for faculty and students. There have been calls for research that demonstrates how OER are being put into practice. This case study examines the responses of users to a voluntary survey in a capstone business course that implemented OER in lieu of traditional textbooks. The study suggests that, for teachers and students, as well as self-directed learners, OER provide a valuable resource to eliminate the pay wall, improve learning design, and support the power of the community through sharing and collaboration.

The purpose of this study was to identify the current status and future development of children’s gardens within public gardens in the United States and to examine their roles as places for children to explore natural environments. This study identified 776 public gardens and examined 163 of those gardens using a comprehensive online survey. The sampled public gardens were widely distributed throughout the United States, although they were located primarily in the eastern and western regions of the United States. We found that 55% of the 163 public gardens that we investigated included a children’s garden at the time of data collection, and 26.4% planned to add a children’s garden in the near future. Children’s gardens found within public gardens were typically in a botanical garden and were added after the public gardens were formed. Most of the children’s gardens had a stated purpose of providing children with environmental education by allowing them to experience the natural environment through play. Most children’s gardens occupied a small proportion, less than 1 acre, of the overall size of a public garden. We also found that demographic and socioeconomic factors influenced the development of children’s gardens within public gardens and public gardens in general.

This paper focuses on significant changes in the overall economics of waste-to-energy (WTE) during the last 30 years. The WTE industry in this country has seen several different business cycles occur since 1975, as different market drivers have caused the industry to rise and fall. This paper compares: (1) those economic factors that were in play in 1975, when the first WTE facility in the United States was built, and the industry was in its infancy; (2) the factors at play when the WTE industry was at its height in 1990; and (3) some of the factors that caused the industry’s steep downward trend since 1994, when the last greenfield WTE facility in the United States was built. The paper will identify changes that have occurred with regard to the pricing of electricity and the ability of public sectors to charge non-market-based tipping fees. The paper discusses the drivers of 2006 and focuses on completed economic factors to be considered when comparing WTE with other waste disposal means. The paper discusses the drivers of 2006 and whether the industry is finally poised to begin an upward turn in the cycle. The paper focuses on the impact of the cost of diesel fuel oil on the overall economics of long-haul transfer, and how that is likely to impact the future development of WTE facilities. The paper also presents a case study of a recent analysis that was undertaken for two counties that were evaluating the financial viability of WTE as compared to other disposal options.

Micro Grids

Like most of the developing countries, India also has a large number of off-the-grid villages. In spite of government's efforts at rural electrification, many villages cannot hope for grid power in the near future because the cost of setting up the distribution infrastructure. But when these villages come on grid, they place an additional demand on the distribution network and most states are already facing several hours of power cuts because conventional electricity is scarce. Thus these villages remain un-electrified for the simple reason that electricity is not available. This case study deals with the innovative business model of the company “Mera Gao Power” which sets up “Solar Micro Grids” in villages. It further analyses the impact of Solar Power on the socio-economic parameters of the villages where the project has been implemented. Further it discusses the various challenges faced by MGP in sustaining and expanding this business model.

One of the most common issues on the word right now is green building technology, with the goal of reducing the development industry's various negative effects on the environment, society, and economy. Because pollution and global warming are quickly expanding over the planet, the world urgently requires a sustainable and reasonable development. Because of the increase in Green House Gases (GHGs), dramatic climatical differences occurring everyday have been noted and are being faced by almost everyone all over the world. Within settled countries such as the United States of America, Russia, Australia, and the United Kingdom, there have already been rigorous steps taken to achieve workable development, as well as rules and regulations enacted by their respective governments to assist and accomplish a workable and environmentally approachable development of their countries. However, emerging countries such as India, China, Sri Lanka, Pakistan, and others are dragging in terms of founding supportable growth and environmentally friendly structures. In addition, there is a deficiency of public understanding about this worldwide issue in these emerging countries. According to surveys and study, these countries are also far behind schedule the established nations of the world. This article discusses the need for maintainable growth around the world, particularly in emerging countries such as India and China, which have enormous land-living masses and are fast emerging, with the potential to become new global superpowers in the near future. It also includes sustainable and monetary research with connections to Indian contexts, as well as a recent live instance study of a freshly built and constructed luxurious housing home in a densely populated area of India. The case study is a inhabited house that is planned and built as a sustainable and green structure in an extremely community inside the state of Maharashtra, India, as India is also known as a country of villages with
