Abstract :

In this work, automation and efficient power generation of a solar park are studied to overcome high inefficiencies that exist in most of the present parks. The inefficiencies arise from many reasons such as stationary condition of the photovoltaic panels to name one. The other problems arise because such parks extend over large areas and maintenance of efficient power generation becomes difficult if all of the panels are mounted such that they track the Sun for maximum power generation. In this work, the entire plant is operated from a single control room and all the tracking machines are commanded to follow the Sun from the control room through wireless signals. The entire motion of the panels is controlled from this room using Arduino Mega microcontroller. In addition, to enhance the accuracy and reliability, several additional measures have been incorporated so that through an accurate feedback system or fault detection mechanism has been provided for in this work.

Abstract :

The principle point of the investigation is to distinguish the utilization of reused material in the concrete as it upgrades the mechanical properties of cement. As "Crumb Rubber" is likewise one of the strong waste which can be utilized as a part of cement by somewhat supplanting fine aggregate. In this investigation "Crumb Rubber" was supplanted by volume of coarse total as 0% to 20% volume of "Crumb Rubber" supplanted coarse aggregates at an interval of 5% increase. Numerous tests were done for fresh concrete (i.e. Slump test, Flow test, Compaction factor etc.) and for hard concrete (i.e. Compressive strength). The elastic properties are also determined from concrete cubes. 3 cubes for each percentage of replacement are casted and tested after 28th days of curing. This attempt of replacing the coarse aggregates with rubber aggregates will save the natural aggregates, reduces weight of structure and also helps achieve sustainability.

Abstract :

A study was carried out to evaluate the effects of heating treatment on compression strength parallel to grain of beech (Fagus sylvatica L.) wood of Albanian origin. The heat treatment was conducted at temperatures 180, 200 and 220°C for 2 hours, at atmospheric pressure. Samples were produced from logs sapwood of origin from central Albania. Before treatment the oven dried density was calculated. The weight loss after treatment resulted from the lowest to the highest temperature respectively 4.34, 6.87 and 10.12%. Regarding to compression strength parallel to grain it was noted a positive approach to heating treatment at atmospheric pressure. The compression strength increased up to 12% for treatment at 180°C. For higher temperatures the strength started to decrease, but in all cases was above compression strength of non treated wood. It seems that thermal treated Albanian beech wood presents a suitable choice for indoor and outdoor utilisation for desks and chairs.

Abstract :

This paper illustrates the role of different membrane technologies in the treatment of VOCs from water and wastewaters. Emerging membrane technologies such as pervaporation (PV) and membrane distillation (MD) gained scientists’ attention as a promising way for water treatment. We have studied and discussed today’s advanced membranes: PV membranes which included polysiloxaneimide (PSI) and polydimethylsiloxane (PDMS), and MD membranes which included electro-spun nanofiber membrane and vacuum membrane distillation (VMD). Studied membranes showed great potential for the treatment of VOCs from water. However, it was found that certain factors like feed temperature, downstream pressure, component volatility (Henry's constant) and VOCs concentration must be considered in the design phase to achieve the ideal treatment.

Abstract :

When a vessel is sailing in rough wave, the large relative movement between the structure and the waves will cause the waves to flood the deck. Deck waves will cause damage to the deck equipment and destroy the integrity of the structure. This condition will not only lead to the loss of economic property, but will also cause serious casualty. The waves on the deck will cause a huge slamming load on the vessel, causing the structure of the bow deck to be damaged by the impact of the water and even causing the entire hull to sink. Therefore, it is very important to analysis the deck wave and study the wave law on the bow deck and structure on the upper deck. When we design civilian or military ships, deck wave is an important factor to structure of vessel, personnel safety and ship performance. In the paper, the container ship is modelled by CAD software and the mesh of wave tank is generated by HEXPRESS function, which is based on Fine/Marine’s adaptive mesh generation technology. In addition to this, numerical model simulates the motion response of the container ship under different wave amplitude and vary ship’s speed in regular wave. Moreover, the variation law of the wave phenomenon on the deck is analysed. Through this research, it is found that the waves on the deck will have a severe impact on the vessel's deck and the equipment on the upper deck. The well-designed wave-stopping structure can effectively reduce the impact of the water body on the structure.

Abstract :

This paper presents a study on protection coordination of protective devices in a radial distribution system by considering penetration of distributed generation. This paper presents the study of protection coordination among various protective devices without and with penetration of DGs in distribution network. The proposed approach is tested on modified IEEE 13 Bus radial distribution system.  When fault occurs in the system, level of fault current changes which in turn changes the operating time of various overcurrent relays. Therefore, it is essential to calculate and recommend method of the relay setting so as to minimize the operating time of relays and also to avoid its mal-operation. In this paper, the protection scheme is optimally developed by taking into consideration the above mentioned circumstances. The operating time of relays can be reduced and, simultaneously, coordination can be maintained by considering the optimum values of time dial setting (TDS). The proposed method used the Genetic Algorithm (GA) for determining the optimum values of TDS of overcurrent relays and hence operating time of circuit breaker CB.

Abstract :

Because the asphalt is kept at 180 C during transportation, the asphalt temperature has an effect on the structural stress of the ship hull. This paper mainly discusses the effect of temperature on the local structural strength of the asphalt ship. Taking an asphalt ship as an example, the whole cargo tank area is modeled by using finite element software MSC. Patran and MSC. Nastran. The model is established by referring to the relevant provisions in the Code for Construction of Steel Inland River Ships. The finite element mesh of the model is generated by choosing the appropriate element type. Applying temperature boundary conditions, the calculated temperature field is applied to the model in the form of load, and other boundary conditions are applied to establish a variety of working conditions, calculate the structural strength, and obtain the stress distribution of the hull. Considering the thermal stress with or without temperature, the effect of temperature on hull structure is analyzed.

Abstract :

In this work we investigate the behavior of the electrical conductivity of polyaniline when small amounts of graphite nanolayers are added to the polymeric matrix and subsequently suffer an aging process. We observed that graphite tends to increase conductivity whilst aging tends to decrease it. On the other hand, absorption of atmospheric humidity tends to increase conductivity. We show that a mathematical model describes with good agreement the dependence of the conductivity with the aging time.
