Vietnam power system is growing fast and will be a large complex system with multiple, diversified and irregularly distributed power sources. Optimal operations and optimal development of Vietnam power system have been studied by many researchers and groups. This paper presents the results of a research on optimal modeling of Vietnam power system taking into account the characteristics of power sources and transmission lines. An objective function and a system of constraints are established to formulate a mathematical simulation model of Vietnam power system with any number of nodes. The model is designed to optimize the development and operation of the power system with the objective of minimizing the cost of power supply and determining the necessary constraints to determine the optimal operating mode for power plants in Vietnam power system.

Textile production plays a major role in the social-economic development and industrialization system of a nation, but the wastewater generated by the industry is one of the most polluting amidst all industrial sectors because the number of contaminants in the wastewater are often very high compared to municipal or domestic wastewater.Characterization and remediation of textile wastewater are essential to achieving a clean and sustainable environment. In this study, discharged wastewater which had been pre-treated with bentonite and alum was collected from a textile industry in Ikeja Industrial Estate, Lagos State, Nigeria. Collected textile wastewater was treated by varying the dose of Activated Rice Husk (ARH), at a constant shaking speed of 150rpm, centrifuging speed of 400rpm at room temperature............

The cooling system of internal combustion engine plays a major role in a vehicle performance. In the present work, a proposed electronic controller for the cooling system is introduced and modelled mathematically to control the engine coolant temperature using a controllable electric water pump and radiator fan. Proportional Integral Derivative (PID) and Linear Quadratic Regulation (LQR) control techniques are considered to design the cooling system controller both the coolant flow rate and radiator fan speed are used to control the engine coolant temperature. The Worldwide Harmonized Light Vehicles Test Cycle (WLTC) is used to test the proposed controller based on mathematical simulation using MATLAB/SIMULINK software. The generated numerical results are presented in thetime domain and compared with theconventional cooling system. The results showed that the proposed controller enhanced the engine coolant temperature either during warm-up or steady-state operation over that of theconventional cooling system.

Water plays an important role in the concrete preparation. It plays an important role in workability and strength of concrete. A new technology known as magnetized water is used to increase the workability and strength of concrete. The magnetized water technology initiated in Russia and China for agricultural and other medical values and now it extends its application in construction industry. Magnetic water has been used in different fields like health care, dairy production, agriculture and oil industries. In this study, the effect of magnetized water on workability, strength and quality of M20 grade concrete with M sand as fine aggregate was studied. Magnetized water is prepared by passing the normal tap water through a magnetic field. When water passes through the magnetic field some of the physical properties of water changes. The water clusters are broken due to magnetic field and which will increase the water activity...............

Proper curing of concrete structures plays a vital role to meet performance and durability requirements. In conventional curing this is achieved by external curing applied after mixing, placing and finishing. Lack of sufficient and efficient curing may result in autogenous shrinkage or early age cracking in concrete. Current situations pose a lot of difficulty in availability of fresh water for curing purposes. Thus researchers around the world are looking forward into a new curing technique. Self-curing or internal curing is a technique that can be used to provide additional moisture in concrete for more effective hydration of cement and reduced self-desiccation. The ACI-308 Code states that "self-curing refers to the process by which the hydration of cement occurs because of the availability of additional internal water that is not part of the mixing water...............

In this article, we have investigated the complete synchronization of two identical non-linear dynamical systems of the three-body problem by taking into consideration the primaries as oblate bodies. We assumed that the primaries are moving in the circular motion around there centre of mass in the non-uniform motion. Here we have designed a non linear controller based on the Lyapunov stability theory. The proposed controller ensures that the states of the controlled chaotic slave system asymptotically synchronizes the states of the master system. For validation of results by numerical simulations we used the Mathematica10 when the primaries are Jupiter and Mars.

The main of this work was to evaluate the microstuctural evolution and the mechanical properties of SAE 1070 steel subjected to a thermomechanical process. The steel was wire drawn up to 12 passes with average reductions between 15 and 21%. The accumulated deformation was 2.52. Following, the material was annealed in ferritic field at the temperatures of 400 ° C, 500 ° C, 600 ° C and 700 ° C, during 5, 10, 15, 20, 25 and 30 min. The microstructural characterization was performed with scanning electron microscopy (SEM) and atomic force microscopy (AFM). The mechanical behavior was analyzed from the results of the tensile test and hardness Vickers test conducted in both, deformed and annealed, material. The microstructural characterization of the deformed material showed the formation of the curling structure..............

In this paper, the problem of steady laminar two-dimensional boundary layer flow and heat transfer of an incompressible magneto hydrodynamic viscoelastic fluid with a presence of Viscous Dissipation and Non-uniform Heat Source/Sink over linearly stretching sheet is investigated numerically. The governing boundary layer equations are reduced into ordinary differential equations by a similarity transformation. The transformed equations are solved using Quasilinearisation technique. The effect of various physical parameters on flow and heat transfer are computed and analyzed through graphs.

Concrete is the second most consumed material in the world after water. It is a combination of cement, coarse aggregates, fine aggregates, water and admixtures. Ordinary Portland Cement (OPC) is traditionally used as a binding material for concrete. It is estimated that when one tonne of OPC is manufactured, one tonne of carbon dioxide is released to the atmosphere. This emission during the manufacturing of cement contributes 7% of the global carbon dioxide emission. So it is important to introduce an alternate binder which will have less carbon footprint than cement. Efforts are made in the concrete industry to use waste materials as partial replacement of cement............

In present days, rapidly developing malware samples stance a deliberate threat to cyber security, exclusively when they are not getting detected by security tools and techniques. Ransomware is a malicious program where the data on victim's computer is encrypted and some ransom is demanded before the ransomed data is decrypted and access returned to the victim. The cyber criminals often demand money in virtual currency, such as "Bitcoin "so that their identity is hidden from the victim. Most common way of transmission of Ransomware is through websites or spam emails. The content of these webs or emails usually claims that, the user has won a prize, or offers access to paid content for free, for example music or movies. The user clicks on the link that they receive through mails and then downloads the malware, this way malware enters in system.

Base isolation is one of the most widely accepted seismic protection systems used in building structures in earthquake prone areas. The base isolation system separates the structure from its foundation and primarily moves it relative to the upper structure. The purpose of this study is to investigate to increase in time period and decrease in base shear due to earthquake ground excitation, applied to superstructure of the building by installing base isolated devices at the foundation level and then to compare the different concepts between the fixed base condition and base isolated condition by using ETABS 2015 software. In this study, G+3 and G+20 storey RCC building are used as test model...........
