Aspects on Implementation of an Integrated Waste Management System in the Rural Area

Abstract

The issue of waste management in terms of environmental protection is one of the important problems facing humanity, especially in the large agglomeration areas, and in the rural area, the interests are more limited.

The present paper presents theoretical aspects regarding the implementation of an integrated waste management system in the rural area.

Cryptocurrency – Sentiment Analysis in Social Media

Abstract

The paper proposes the exploration, identification and development of a Java solution for extracting the sentiment related to the cryptocurrencies phenomenon, from the content of the posts of certain popular social networks.

Detecting the positive, neutral or negative character of the sentiment is adopted as a relevant method of establishing the nature of the human perception on the topical issue defined by cryptocurrencies.

The Effect of Squeeze Pin Dimension and Operational Parameters on Material Homogenity of Aluminium High Pressure Die Cast Parts

Abstract

The present paper is an experimental study on the squeeze pin effect on the high pressure die cast aluminium parts, as a way of improvement of material homogenity on various and big wall thickness castings. Squeeze is used in high pressure die casting technology for optimizing homogenity of big wall thicknesses of die cast parts working as structural, mechanical and hydraulic components, made of different aluminium alloys such AlSi alloys. The objective of this research is to highlight the primary and secondary effects of squeezing on the structural homogenity of high pressure die cast aluminium parts, as well as the dependence of the effects on the squeeze pin dimensions and the operating parameters.

Examination of the Types of Erosion and Introduction of Protective Measures to Prevent Soil Loss

Abstract

Soil erosion is the most important challenge of the biosphere. Soil is one of the most important and most valuable natural resources. It meets the essential needs of the world. If the soil is not well preserved, then hunger will conquer all over the globe. This article tried to identify types of erosion and provide solutions to prevent it to protect this main material by examining the effects and results.

Some Aspects about Theoretical Static Rigidity and Experimental Static Rigidity of a New Elastic Coupling with Cylindical Bolts and Nonmetallic Elements

Abstract

The elastic couplings are frequently used in mechanical transmissions design, to take over the radial, axial and angular misalignments and also to take over the shocks and the overloads that could appear. In this paper is presenting some aspects about the construction of couplings with bolts using non-metallic elements, e.g. rubber, having different hardness, the elements involved in torque transmission, in this case elastic elements, having also different dimensions or forms, in the way to have a good elasticity and capacity of vibration absorbtion, determining theoretical static rigidity and experimental static rigidity of a new elastic coupling with cylindrical bolts and nonmetallic elements and compare of results for these values.

Study on the Westley Maclean Model and the Co-Orientation Model and their Exemplification in an Industrial Enterprise

Abstract

The present paper makes an incursion into the new and complex models of communication that can be found in literature, trying to identify their graphic decoding and their applicability in an industrial enterprise. The authors identified real examples for each model under investigation, so the purpose of the paper is to emphasize the importance of communication and the applicability of the new methods of communication in engineering.
