In this paper unique approach for standalone hybrid model power generation system is been developed using MATLAB Simulink. While implementing this technique advance power control technique which used a four power sources, solar, wind, diesel generator and storage battery is demonstrated which is generally not use in commercial power system. Serious efforts has been put while completing this project for active, reactive and dump power control. For grid connected renewable energy systems the power deficit for the load will be compensated by the grid conventional power. As the powers from renewable energy resources is not constant because of environmental changes the load demand will be compensated from the utility grid during such condition. For standalone system comprising renewable source needs back up devices to ensure supply to increased power demand. In this thesis a PVA and wind farm is supported with battery energy storage system and diesel generator during increase in load demand. The modelling of the test system with and without back up sources is analyzed in MATLAB Simulink environment.

This method is used to optimize dc-link voltage of Unified Power Quality Conditioner (UPQC) based on load compensation requirement using Reduced Switch Count Multi-Level Converter (RSC-MLC) integrated with Photo-Voltaic (PV) system. During off-peak loads, the dc-link voltage can be brought down to a lower value, which will reduce the voltage-stress across switches of inverter and minimizes the switching losses. The variation of dc-link voltage is provided using RSC-MLC which requires dc voltage supply. This method utilizes renewable resources of energy such as solar cells as the dc voltage source. This method is capable of compensating sags, swells, unbalance and harmonics demanded by three phase unbalanced and non-linear loads connected to the distribution side, leading to improvement of power quality. It is also capable of providing real power support to the load and thus prevents source from getting over loaded whenever required.

For intelligent dc distributed power systems (DC-DPSs), data communication plays a vital role in system control and device monitoring. To achieve communication in a cost-effective way, power/signal dual modulation (PSDM), a method that integrates data transmission with power conversion, can be utilized. In this paper, an improved PSDM method using phase shift full-bridge (PSFB) converter is proposed. This method introduces a phase control-based freedom in the conventional PSFB control loop to realize communication using the same power conversion circuit. In this way, decoupled data modulation and power conversion are realized without extra wiring and coupling units, and thus, the system structure is simplified. More importantly, the signal intensity can be regulated by the proposed perturbation depth, and so this method can adapt to different operating conditions. A PVA is connected as input with variable solar irradiation to the PSFB. The PSFB is controlled by feedback loop-controlled fuzzy controller which maintains the output voltage at 100V even during change in input voltage. A simulation is carried out in MATLAB with fuzzy controlled carrying the phase angle of S3 and S4 switches to ensure maintenance of output voltage at 100V. All the graphs are represented in time domain analysis with variable input and constant output voltages.

This paper proposes a solar photovoltaic (PV) fed water pumping system driven by a brushless DC (BLDC) motor. A promising case of interruption in the water pumping due to the intermittency of PV power generation is resolved by using a power grid as an external power backup. The power is drawn from the grid in case the PV array is unable to meet the required power demand; otherwise the PV array is preferably used. A unidirectional power flow control for the same is developed and realized through a power factor corrected (PFC) boost converter. The proposed system and control enable a consumer to get a full volume of water delivery throughout the day and night regardless of the climatic condition. The utilization of motor pump at best is thus made possible in addition to an enhanced reliability of the pumping system. The power quality standards required at the utility grid are met by the developed control A grid interface PVA source is used for running a BLDC motor water pumping system. The PVA is connected to booster converter for constant voltage generation during solar irradiation change. The booster converter is controlled using MPPT controller which is updated to beta method from conventional incremental conductance method. The reaction time and power output of the PVA are compared with these two MPPT methods. The graphs of voltages and powers of PVA and grid are generated with respect to time using MATLAB Simulink environment. The MATLAB/Simulink based simulations and the performance analysis are carried out to demonstrate the applicability of the system.

In this paper a new high step up DC to AC converter is introduced with controlled with PWM technique. The output three phase AC voltage is interconnected to grid through LC filter. The converter is connected to low voltage renewable source like PVA or battery. The low voltage is stepped up to higher voltage using the proposed converter with coupled inductor and resonant switched capacitor. Because of the synchronous rectification Boost unit and multiple coupled-inductor-SC units the structure can therefore be easily extended for ultrahigh voltage gain. The power electronic switches are operated with soft switching with reduced voltage stress increasing the reliability of the converter. MOSFET power electronic switches are used to control the circuit output voltage with high switching frequency in the range of 100 kHz. This high switching frequency reduces the ripple in the DC voltage output reducing the harmonics in the AC voltage side of the converter. The AC voltage output of the converter is synchronized to the grid with feedback loop control using synchronous reference frame method. The complete modelling is carried out in MATLAB Simulink environment with discrete analysis of the circuit. The graphs are plotted with respect to time and are explained using GUI environment.

The present work proposes an optimized energy efficient routing protocol for the enhancement of network lifetime n Wireless Sensor Networks. The essence of the protocol lies in the fact that it changes the cluster size as well as the cluster head dynamically at the beginning of every iteration. Moreover, a threshold based approach is used so as to reduce the total number of transmissions thereby bringing down the energy consumption. A delay time is introduced to re-transmit the data in case the transmission thresholds are not exceeded. the average energy of a node and the network lifetime. The network lifetime is evaluated based on the number of rounds transmitted with respect to the number of nodes in the network. It has been found that the proposed algorithm attains almost negligible number of dead nodes over the entire duration of the transmission. The average energy of the nodes decreases with the number of iterations though. Finally it has been shown that the proposed protocol is capable of transmitting more number of rounds with respect to the number of nodes. Thus it can be said that the proposed system achieves better performance compared to previous techniques.

The traditional style of healthcare is based on visiting a hospital or clinic to meet a doctor face-to-face and to pass through certain monitoring and analysis procedures using the professional medical equipment and direct expertise. This form of healthcare operation is expensive. Health policies and decisions are based on reliable, up-to-date and accurate data which should be appropriate and effective. In this paper we review the various data mining techniques for the health care industries, also using some smart techniques such as the internet of things, evolutionary techniques and the other methods.

The performance of wireless sensor networks is a domain that attracts a lot of attention lately. Research mainly focuses in controlled environments, where wireless sensors tend to replace old fashioned wired devices that are being used to monitor specific parameters like temperature, pressure, vibration etc. In such environments, wireless sensors periodically send their measurements, hop-by-hop to the sink, in a control center. In this paper we focus on the design and development of efficient model, if applied to a wireless sensor network, will be able to guarantee the performance of the network without imposing any risk to the application. Risk to the application may also occur when data packets arrive with delay out of bounds, according to the application demands.

The main aim of our project is to improve the strength characteristics of pervious concrete. But it can be noted that with increase in strength. Hence, the improvement of strength should not affect the strength property because it is the property which serves its purpose. In this investigation work the compressive strength of pervious concrete is increased by a compressive strength of pervious concrete is increased by 13.92% for 28 days when 12% RHA was replaced in the place ofcement s were added to standard pervious concrete Pervious concrete is a special type of concrete, which consists of cement, coarse aggregates, water and if required and other cementations materials. As there are no fine aggregates used in the concrete matrix, the void content is more which allows the water to flow through its body. So the pervious concrete is also called as Permeable concrete.

A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer request or demand. The supply chain not only includes the manufacturers and suppliers, but also transporters, warehouses, retailers, and finally the end consumers themselves. The objective of every supply chain is to maximize the overall value generated. The value a supply chain generates is the difference between what the final product is worth to the customer and the effort the supply chain expends in filling the customer’s request. An important phenomenon in Supply Chain Management is known as bullwhip effect (BWE), which suggests that the demand variability increases as one moves up a supply chain. Bullwhip effect is an undesirable phenomenon in the supply chain which exacerbates the supply chain performance. The impact of BWE is to increase manufacturing cost, inventory cost, replenishment lead time, transportation cost, labor cost for shipping and receiving, cost for building surplus capacity and holding surplus inventories, and to decrease level of product availability and relationship across the supply chain. Various factors can cause bullwhip effect, one of which is customer demand forecasting. In this study, impact of forecasting methods on the bullwhip effect and mean square error has been considered. The preceding study highlights the effect of forecasting technique, order processing cost and demand pattern on BWE and mean square error (MSE). The BWE and MSE have been evaluated using MATLAB coding. The results were analyzed using ANOVA and Fuzzy Logic, and finally the optimal parameters for minimum values of BWE and MSE have been determined

It is recognized that mostly researchers have make effort on different alternate material like particularly industrial and agro-based squander materials like palm oil fuel ash, rice husk ash, quarry dust, fly ash, copper slag, coal ash, corncob ash and so on.

We are utilizing the industrial waste material to create a higher quality concrete. The natural problem can be tackle by substitution of industrial squanders and by item. A portion of the squander items which have pozzolanic properties and which had been considered for use in mixed cements incorporate .It is recognized that researchers have make effort on different waste materials. But it is recognized that very few literatures are available on the consequence of squander materials (wood ash, quarry dust, copper slag) on the cubes, beams and cylinders strength, using destructive and non-destructive method. In this analysis trial would be made to execute experimental study on standard concrete cubes, beams and cylinders. For there, M25 grade will be utilized with the age of 7th, 14th and 28th days.

Due to growing environmental awareness and stern regulations on managing industrial waste, the world is increasingly turning to researching properties of industrial wastes and finding solutions on using their valuable component parts so that those might be used as secondary raw material for other industrial applications. Silica fume is the bi- product of the ferrosilicon alloy production and Fly ash is by-product of coal thermal power plants. To date, these by-products are being used in other industrial branches and in the field of civil constructions, such as in cement manufacturing along with clinker and in masonry work for civil works. Considering the specificity of physical and chemical properties of fly ash and silica fume and a series of possibilities for their use in concrete, this research work demonstrates the possibilities of using fly ash and silica fume together as partial replacements of cement in concrete. It has been observed from the 28 days tests of compressive strength of concrete that compressive strength in fly ash modify concrete 20FA has maximum strength. In silica fume modify concrete 10SF has maximum strength value. While the combination of fly ash and silica fume 20FA10SF has maximum strength value. As the percentage of fly ash increases in the mix when compared with controlled concrete it increase up to 20% and then decreases. The compressive strength analysis carried out in this work gives a deeper insight into the cementitious properties and pozzolanic behavior of such by-products when used for construction purposes. The results show that the strength properties of concrete vary significantly when cement is partially replaced by silica fume and Fly ash.

The control of cost and time in construction projects is one of the most important issues in construction since the emergence of the construction industry. A successful project should meet not only quality output standards, but also time and budget objectives. The management and control of cost and time in construction is fundamental in every project. An effective cost and time management and control technique for construction projects is important in managing risk of cost overrun and delay in completion of projects. Construction projects are becoming more complex as they now involve many stakeholders from different disciplines. The emergence of Building Information Model (BIM), an alternative technology is believed to solve issues related to project cost and time control as it efficiently increases collaboration between stakeholders. The aim of this paper is to review and summarize the causes of delay and cost overrun in construction industries, which are the main causes of disputes and abandonment of projects in the industry. It was found that delays and cost overrun eat deep into the industry and leave the construction industry with a bad image for decades even with rapid advancement in technology. The review of the applications of BIM showed that most of the applications are geared towards minimizing construction cost and time spent on projects. This means that the use of BIM in the management of construction projects has great impact on project cost and time.
