The difficulties encountered in the canteen due to huge rush by visually impaired students in particular and by other typical students and employees, in general, is taken into consideration. Each user is recognised using face recognition technology. For the convenience of those who are blind, a voice-over system is employed to guide them through the buying process. Before collecting the food, a second interface is made available at the retailer to confirm the user's identification. The buyer will be provided with a special token number after pre-ordering the necessary meal packs. Additionally, the store can accurately quantify the number of packets needed, avoiding food waste.

Key words: Assistive Technology, Visually Impaired People

Al año a nivel mundial mueren aproximadamente más de 2 millones de personas porproblemas relacionados con enfermedades del hígado [2]. En cambio, México a lo largo de los años ha mostrado un aumento en defunciones debido a padecimientos relacionadas coneste órgano, que, aunque no se han mostrado de manera excesiva, las cifras han idoincrementando desde el 2013 con 34,826 lo cual genera que las enfermedades de esteórgano fueran la quinta causa de muerte en el país [3]. En los años consecutivos estascifras aumentaron de manera significativa, en el año 2020 el Instituto Nacional deEstadística, Geografía e Informática (INEGI) registró 41,982 muertes por que se posicionó en el sexto lugar a nivel nacional pero aun así se nota un incremento significativo [1].

Vibration is a challenging problem in the process of aircraft design. The expansion of technologies that optimize and reduce the aggregate mass in aeronautical structures or change the traditional material for composite materials may cause structural faults and, thus, require detailed analysis during their development. In this way, experimental modal analysis, in conjunction with finite element methods, has been used to investigate and obtain the necessary dynamic characteristics of the aircraft. The information is applied to predict and quantify possible structural failures. Considering.....

The role energy plays in our world today is immeasurable. Energy generated from petroleum reservoirs and other fossil sources has been of high demand which has resulted in environmental catastrophe such as depletion of ozone layer, emissions of trace and greenhouse gases, increased ultraviolet and infrared radiations from the sun to the earth etc. These hazards associated with the use of fossil fuels and the depletion of petroleum reservoirs has led to the search for alternative source of fuel that are environmentally friendly, re-useable and sustainable. Biodiesel produced from vegetable oil or animal fats is one of such alternative fuel. In this research, Calcium Oxide (CaO) nano-catalyst from duck, guinea fowl and turkey eggshell were investigated for the production of biodiesel from waste cooking oil (WCO) under the same operating conditions. The CaO nano-catalyst was obtained by calcining........

Urbanization is the integral part of the development process, especially for those nations who are rapidly growing. It brings about the social transformation, from traditional societies to present modern urban communities. The smart cities is a collaboration of technology into strategic approach of sustainability. The programme will provide the city where information technology is the principal infrastructure and the basis for providing the essential services to the residents. The need of the smart city arises with the huge migration of the rural population to cities. Preventing the creation of waste is the first step in the waste management. It is the focus of both Swedish and European waste legislation........

Nowadays, construction claims have become an indispensable part of the construction projects. It is commonly recognized that the number of claims and disputes has been increasing and has become a burden to the construction industry. Avoiding claims requires the understanding of such claims causes. Since the importance of claims in construction projects as claims have pronounced effects on the project implementation, the need for claims mitigation method is evident. In this research, a literature review was conducted to identify the reducing factors of claims in international literature. Using expert interviews the factors modified according to Egyptian construction industry by.........

Nepal is an agricultural country and agriculture is the mainstay of national economy. Rice is a major staple crop of the country. During the year 2017/018, rice contributed 44.66 per cent to the total edible cereal grain production in the country. Rice is a labor intensive crop and youth migration has created a situation of labor scarcity. Introduction of mechanization in rice cultivation is one of the best solutions to get rid of labor scarcity and increase production of rice. AMTRC, Nawalpur, Sarlahi has been carrying out different research works on use of different machineries and cultivation practices in rice farming. It carried out a study in 2016/017 and 2017/018 on uses of different machineries in three replications with five treatments........

In the current era, environmental degradation has become a growing problem and concern of people. It has serious effects on all the elements of the society. Government, NGOs, women are all trying to conserve the environment. Keeping in mind that environmental conservation is everyone's responsibility, the present study is an attempt to examine the knowledge, attitudes and practices of women regarding environmental conservation and protection. This paper focuses on the theories of ecofeminism, environmental movements and activities that bring about changes in the conditions that threaten the environment. The present paper is based on the secondary source and tries to understand the role of women in the environment conservation.

The conventional method of mungbean (Vigna radiata) cultivation is direct broadcasting involves land preparation and seeding which is laborious, time-consuming and cost-intensive. Conservation agriculture-based technologies are becoming increasingly popular among the farmers due to having early planting scope, the minimum cost of production, improving soil health and sustainable environment. This study was conducted to evaluate the performance of a power tiller operated zero-till drill for the adoption in mungbean cultivation. Overall performance was evaluated based on seed rate, number of plants per unit area, number of pods per plant, number of seeds per pod and grain yield, net saving and benefit-cost ratio, and compared with the conventional method. Results showed that average seed rate was 30.0 kg/ha and 35.5 kg/ha for zero tillage and conventional method respectively, which indicates that.........
