Rubber Waste is produced largely worldwide every year. Its discharge is challenging to the environment and its decomposition takes long time. Therefore reuse of rubber in concrete mix is plausible. It was added to concrete as coarse aggregate and its different properties like compressive strength and flexural were investigated and compared with ordinary concrete. Results show that rubberized concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. This study is evaluating the properties of concrete mix with adding crumb rubber. In this study we focus on compressive and flexural strength of concrete by adding several percentages (1 to 5 %) of crumb rubber replacing cement in the mix. Using crumb rubber in concrete decreases compressive and flexural strength which means that it may not be suitable for rigid pavement. Rubber crumb size has an effect where fine grain rubber seems to minimize loss in concrete mix by 11% per 5 % increase in rubber. However, rubber enhances other properties that may be useful for special uses like noise reduction and water absorption reduction. The loss in compressive strength of rubberized concrete can be compensated by additives like silica.

Clay soils are generally linked to the shrink-swell phenomenon. This phenomenon causes many disorders in the infrastructure and in particular railway infrastructures, which are extremely sensitive to soil deformations. This is mainly reflected through the deterioration of the geometry and performance of the railway, and it has a notable impact on maintenance and servicing costs. This paper presents the analysis of the settlement of clay soils, on the one hand on the basis of the results of geotechnical tests carried out in-situ and in the laboratory and on the other hand by using numerical modelling using the finite element method. This analysis shows that the results are very close and allows a preventive mapping of the risk distribution along the section of the studied railway track. To mitigate these risks, the feasibility of the substitution technique was studied through removing 4 m from the soil and replacing it with selected materials. This technique has shown a significant improvement in the performance and behavior of the clay formation.

Greener and more sustainable construction projects have become the target of most agencies and officials, worldwide. With the increase of solid wastes, especially plastic waste, many attempts are made to incorporate these waste materials into construction projects. However, there are sound concerns about the side effects of adding plastic waste to construction materials, mainly Portland Cement Concrete (PCC) mixes. Thus, this study was conducted to investigate the effects of adding plastic waste fibers to PCC mixes when it comes to performance of rigid pavements. Low percentages (25%, 0.375%, and 0.5%) of plastic waste fibers were evaluated. KENSLAB software was utilized to determine stresses, deflections, and Cracking Indices in a rigid pavement. Based on conducting tests and analysis, 0.25% plastic waste fibers could be considered the optimal percentage, since it would enhance the performance of a rigid pavement and extend its design life. However, loss of workability of PCC mixes with plastic waste fibers may be a concern and should be taken care of by adding super plasticizers to counter act this loss.

The charging flocculation agent is produced from volcanic ash by calcining it in the special firing furnace to generate high porosity, then applying a strong electric charge to some substances included in the ingredient of the ash by special processing. The agent consists of the natural inorganic substances, therefore, it is considered as an ecological water depurative. The agent has rapid rate of flocculation and sedimentation, therefore, the facility cost is cheaper, post-processing sludge is simplified, operation cost is low, and efficiency is high. Apart from effective treatment of the waters contaminated with high content of turbidity and color, the agent can remove some heavy metals such as Fe, Mn and some organic substances (COD), therefore, it have been used for water supply treatment. The results of application of the flocculation agent in Ha Tinh and Vinh Long provinces on small- and medium water supply facilities with capacity of 50 litters and 500 liters per a hour shows that the quality of the treated waters met the QCVN 02:2009/BYT. When using the flocculation agent and the disinfectant agent, the quality of treated waters can meet all 109 parameters regulated in QCVN 01:2009/BYT.

Received polymeric materials with the use of wasted polyethylene of PE-500 and PE-1000 grades can serve, as construction materials at regimes, which correspond to characteristics of new PCM. Presence of carbon fibers in composites such as UPA-6-30+PE-500 (10%) and UPA-6-30+PE-1000 (10%) allows applying details, made of these materials without normative greasings. The use of waste polyethylene of PE mark decreases physicomechanical characteristics in received PCM with the exception of impacting viscosity. It is shown that such an indicator as the stress of the boundary of the volume of compression is high (about 100 MPa), which indicates the possibility of using PCM data, for example, for bearings of parallelogram mechanisms of sewing machines, where the pressure value is within the range of 23 to 30 MPa.

In this article, we investigate energy efficient power control for the uplink of an OFDMA (Orthogonal Frequency-Division Multiple Access) single-cell communication System. We assume that the user equipments decide freely their power level on the available subcarriers of the system in order to maximize their individual Energy Efficiency (EE) while respecting minimum normalized rate requirements to guarantee a certain Quality of Service (QoS). We use the non-cooperative Game theory to demonstrate that users will end by learning the equilibrium. The solution of the Game is given as a water-filling like power allocation. Furthermore, we implement a distributed power allocation scheme using two ways: a) Fractional Programming techniques: an existing Algorithm for power allocation b) A closed form expression: our proposed algorithm for power allocation. Simulations show that the proposed algorithm performs better in terms of Spectral Efficiency (SE) even though it has less EE than the reference algorithm.

In the following document, we realize the development and evaluation of a device capable of identifying the dream state of a person for the control of a home automation system. This takes advantage of the user's breathing time lapses to achieve the detection of the sleep state and is integrated into a system arranged for the application of the domotic control in a place. It is evidenced through an analysis of the electricity in a house as the implementation of the system generates significant savings and how its application would improve the quality of the user's sleep. With the proposed design an optimal response is observed in the detection stage, where the measurements of the quality of service (QoS) parameters indicate its correct operation.
