A conceptual model for integrating sustainable supply chain, electric vehicles, and renewable energy sources

The effects of climate change can be seen immediately in ecosystems. Recent events have resulted in a commitment to the Paris Agreement for the reduction of carbon emissions by a significant amount by the year 2030. Rapid urbanisation is taking place to provide room for an increasing number of people’s residences. Increasing the size of a city and the number of people living there creates a daily need for consumable resources. In the areas of transportation, supply chains, and the utilisation of renewable energy sources, deliver on pledges that promote the accomplishment of the Sustainable Development Goals established by the United Nations. As a result, the supply chain needs to be handled effectively to meet the requirements of growing cities. Management of the supply chain should be in harmony with the environment; nevertheless, the question of how to manage a sustainable supply chain without having an impact on the environment is still mostly understood. The purpose of this study is to present a conceptual model that may be used to maintain a sustainable supply chain with electric vehicles in such a way that caters to both environmental concerns and human requirements. As part of the continual process of achieving sustainability, interrelationships between the various aspects that are being investigated, comprehended, and applied are provided by the model that was developed. It is self-evident that governmental and international organisations that are concerned with supply-demand side information will benefit from such a model, and these organisations will locate viable solutions in accordance with the model’s recommendations. Beneficiaries consist of individuals who are active in the supply chain and are concerned with supply-demand side information. These individuals also need to understand how to effectively manage this information

NOVEL IDEA FOR IMPROVING VIDEO CODECS IJECET © I A E M E

ABSTRACT Nowadays, as the usage of internet is increased at such an extent that we cannot imagine our lives without internet. The internet facilitates us with its valuable services like online video sharing, viewing and downloading, e-advertising, video conferencing, video telephony etc. These all services consume most channel capacity, so the biggest problem faced is delay in transfer of multimedia files and bandwidth required for the transmission of video in terms of cost of transmission. So to overcome the problem video compression is necessary. The challenges faced by the video compression algorithm, is to maintain tread off between: quality of video, compression ratio and computational complexity. MPEG-4 is a latest algorithm but having higher computational complexity, as it is object based compression algorithm, whereas MPEG-2 is somewhat older but having low computational complexity and giving less compression as it is subjective compression. Here in this paper, authors have introduced modification in MPEG-2 algorithm to achieve compression almost nearer to MPEG-4 with little increase in the computational complexity of the algorithm

Modeling and analysis of quadrotor using sliding mode control

In this paper, we present a model of a four rotor unmanned air vehicle (UAV) known as quadrotor aircraft. Quadrotors have generated considerable interest in both the control community due to their complex dynamics and military because of their advantages over regular air vehicles. The model is used to design a stable and accurate controller. Main aim of this paper is to achieve stable hover, with addition of variations in altitude based on human input for thrust. This paper explains the developments of a PD control method and sliding mode control for a fully-actuated subsystem of a quadrotor to obtain stability in flying the Quadrotor to a stable hovering position. The model has four input forces which are basically the thrust provided by each propeller

Domestic artefacts: sustainability in the context of indian middle class

Sustainability has become one of the important research topics in the field of Human Computer Interaction (HCI). However, the majority of work has focused on the Western culture. In this paper, we explore sustainable household practices in the developing world. Our research draws on the results from an ethnographic field study of household women belonging to the so-called middle class in India. We analyze our results in the context of Blevis' [4] principles of sustainable interaction design (established within the Western culture), to extract the intercultural aspects that need to be considered for designing technologies. We present examples from the field that we term "domestic artefacts". Domestic artefacts represent creative and sustainable ways household women appropriate and adapt used objects to create more useful and enriching objects that support household members' everyday activities. Our results show that the rationale behind creating domestic artefacts is not limited to the practicality and usefulness, but it shows how religious beliefs, traditions, family intimacy, personal interests and health issues are incorporated into them

Sharing, saving, and living well on less: supporting social connectedness to mitigate financial hardship

This article contends that problems such as poverty and economic disadvantage are equally social in their nature as they are economic. As such, a social frame of reference is helpful in design. Using a qualitative approach, the authors studied the ways that 13 Australian households living on a low income manage, organize, and interact in their everyday financial activities and what this means for designers of technology that might assist them with this. The article highlights the highly social nature of many practices concerned with managing and saving money. Implications are provided for how these practices may be supported through fostering social connections and how informal and sharing economies may be leveraged to provide value to those experiencing financial hardship. An argument is made that classifying an otherwise heterogeneous population based on income alone is reductive. In response, the authors propose a rationale for amending the “low income” demographic classifier, incorporating a broader measure they tentatively term Social–financial Connectedness, which captures the importance of social connections in overall financial well-being and identifies people’s capacity to live well and share, irrespective of their financial circumstances
