Nowadays, in Speed breaker systems that receive their kinematic energy from vehicles passing over them in which generated kinetic and potential energies are converted to electrical energy. The speed bumps systems transfer energy in axial direction by means of spring in which energy is stored during operation. Speed bumps constitute an excellent solution for energy recovery in countries that are poor in national energy resources such As Lebanon; Lebanon suffers from limited natural resources that are used in generating electrical power. Hence, lighting streets during night time is a secondary to the local authorities since providing power to streets lighting needs a considerable amount of power. In this context, the present work concerns a prototype of speed bumps as well as an experimental study of the system performance.

Concrete is very wide topic in civil engineering field. Modification of concrete is very essential for eco-friendly environment for present scenario. Show we are using agricultural waste in concrete to modify the concrete and to reduce problems of waste disposal and land utilization for waste. The agricultural wastes which are used in this project: - i). Coconut shell ii). Rise husk ash Coconut shells are by-products of coconut oil production. Coconut shells are used in the production of activated carbon due to hardness and high carbon content. Concrete using Coconut Shell aggregates resulted in acceptable strength required for structural concrete. Coconut Shell may offer itself as a coarse aggregate as well as a potential construction material in the field of construction industries and this would solve the environmental problem of reducing the generation of solid wastes simultaneously. . The impact resistance of Coconut Shell concrete is high when compared with conventional concrete. Moisture retaining and water absorbing capacity of Coconut Shell are more compared to conventional aggregate. Cost reduction of 40% can be achieved if coconut shells are used to replace gravel in concrete. The amount of cement content may be more when Coconut Shell are used as an aggregate in the production of concrete compared to conventional aggregate concrete. Thus cement can also be replaced by rice husk ash which is an agricultural waste to make it low cost material. Rice husk ash (RHA) is a by-product from the burning of rice husk. This husk contains about 75 % organic volatile matter and the balance 25 % of the weight of this husk is converted into ash during the firing process, is known as rice husk ash (RHA). This RHA in turn contains around 85 % - 90 % amorphous silica. Thus Rise husk is replaced partially by cement and Coconut shell is replaced by aggregate in various proportions. Then the concrete specimen is compared by testing on 7th, 14th and 28th day with water cement ratio of 0.5. Compressive strength tensile strength, workability, etc. will be shown in result. According to result of RHA moulds and coconut shell moulds the ratios are formed for using RHA and coconut shell together in concrete.

Material handling is one of the most crucial issues that should be taken into account for eliminating waste, reducing the cost and just in time based delivery of the product. Many industries spending millions of bucks for the transportation of the goods. An effective transportation management system has to be implemented to control the cost of transportation and inventory. Optimized milk-run concept can be utilize to overcome the issue related to the supply chain management system. Milk-run material supply system is the cyclic trips, where either goods are collected from several suppliers and delivered to one customer, or goods are collected from one supplier and delivered to several customers. The objective of this research is the minimization of the total material handling and inventory holding cost. It is also concentrated on just in time delivery to enhance the customer satisfaction. These saving of cost could be either use for reduction of the product cost, which will boost up the sales or to lift the profit margin of the organization. The purpose of this research is to develop a mathematical model and a heuristic approach, which is utilize to construct the routes, calculate the associated cost and determine the service period for the design of a milk-run material supply system with simultaneous pick-up and delivery. The material supply by this system occurs on a just-in-time basis from a regional offices to several stations of the courier service. Besides, the proposed heuristic approach intends to construct routes based on an initial service period value and attempts to improve the solution by considering different period values. Furthermore the scheduling of the vehicles is calculated based on demands and routes of network. The most optimum solution is decided on the basis of the least total transportation cost and minimum time. Genetic algorithm is proposed to solve the vehicle routing with simultaneous pickup and delivery within time frame (VRPTWSPD) problem related to milk-run concept. Algorithm is applied by the help of MATLAB and results are presented. The result showed the performance and effectiveness of the algorithm.

Wireless sensor networks (WSN), sometimes called wireless sensor and actuator network (WSAN), are spatially distributed autonomous sensor to monitor physical or environmental condition, such as temperature, sound, pressure, etc. One class of applications envisaged for the IEEE.802.15.4 LR-WPAN (Low Data Rate Wireless Personal Area Network) standard is wireless sensor networks for monitoring and control applications. Wireless sensor networks provide a new paradigm for sensing and sending information. Current WSNs typically communicate directly with a centralized controller or a satellite, thus communication between the sensor and controllers is based on a single hop. An on-going area of research is, where WSN nodes or terminals that communicates with each other forming a multi hop network. Such WSNs could change their topology dynamically when connectivity among the nodes varies with the time due to node mobility.

TIG welding is very commonly used method in production engineering for joining metal parts. There are so many process parameters which affect the quality of weld joints. This process is widely used for welding of various metals and alloys like different grades of SS (stainless steel), Titanium, Aluminium, etc. Welding has been applied to various industries in particular, construction, automotive, aerospace and microelectronics etc. However there are many methods for welding the work pieces and one of the methods among these is vibratory welding. It has the advantages of less investment, more convenient operation, less pollution and shorter manufacturing period. In vibratory welding, work piece vibrates in the whole welding process and it mainly effects the welding solidification to improve the quality. Vibration facilitates the release of dissolved gases and the resulting weld beads greatly exhibit reduced porosity. Mechanical properties of the welds prepared under vibratory conditions are dependent on the structural changes of the welds. Many articles describe the benefits of vibration during welding on mechanical properties of weldments. Present work will emphasize on the effect of mechanical vibration on inner defect, and mechanical property of dissimilar and similar metal joints in TIG welding. As a result, this review will provide the improvement in mechanical properties and reduction in defects of weld joints by applying mechanical vibrations during the tungsten inert gas welding process of joining. The reduction in defect of welded joints can be measured with help non-destructive testing methods such as Penetrant Testing.

The use of fibre reinforcement concrete provides the ductility and toughness required for higher strength. The single type of fibre with reinforcement in concrete improves the mechanical properties at certain level. In concrete the different type of pozzolanic materials are normally used to improve the properties. GGBS can be used as partial replacement of cement for better performance and it helps in producing high strength concrete because of the total participation in hardening process. Fibres are generally used to resist cracking and to assist in strengthening of concrete. Adding a steel and sisal fibres to concrete at low volume dosage rates provides benefits not available in conventional concrete. The use of GGBS, steel and sisal fibre improves the shear strength, torsional structural strength, impact strength and enhanced fatigue and crack resistance. This study focuses on the compression, split tensile and flexural strength properties of M20 grade concrete. The fibre reinforced concrete contains different percentage of GGBS used as partial replacement for cement in addition to steel and sisal fibre. The GGBS is added to the concrete with the percentage of 0%, 10%, 20% and 30% by the weight of cement and 0%, 0.5%, 1% and 1.5% of steel and sisal fibre is used. Concrete specimens casted are cubes, cylinders and beams. After completion of curing process the concrete specimens are tested at 28 days and the final test results are recorded, analyzed and discussed. The strength achieved due to the addition of GGBS and fibres is compared with the nominal concrete and also the strength achieved by GGBS with the addition of steel fibres is compared with the sisal FRC.
