Efficient supply and distribution of energies in the power sector is a very important issue for development. The smart grid technologies allow the distribution and production of the commodity flow so that the proper communication is maintained and optimized depending on the demand. All the demand sites will be connected to the grid and the load over each sources are to be distributed in such a way that the load is minimized per source so that they can keep some of the power as residue. The power flow is required to be maintained continuously by choosing the best path which has minimum cost and transmission loss. For this different optimization technique could be used to be finding an optimal or maximal flow path for transmission. In this paper, we propose a deterministic graph model to represent the flow in the power grid and apply tabu-based heuristic local search to find the optimal flow such that the load shedding is being minimized. We applied a number of local search algorithms on different data sets and the results shows the potential for applying such meta-heuristic algorithms to solve the problem.

Main objective of this paper is to suggest an electricity generation system based on renewable energy sources to fulfill the electrical demand of remote villages of a developing country like Bangladesh. The suggested system is composed of photovoltaic array, fuel cell stack, electrolyzer and hydrogen storage tank. This system will replace the conventional method of storing energy by introducing hydrogen storage system. The system is known as Solar PV-Hydrogen Fuel cell system. The optimization and the simulation of the proposed system were performed with Hybrid Optimization of Multiple Energy Resources (HOMER) software. In order to determine the optimal combination of the system, different combinations of PV arrays, Fuel cell, Electrolyzer and Hydrogen storage tank were selected on the basis of the Net Present Cost (NPC).

In this work, a tree-based adaptive routing for multi-channel wireless sensor network is proposed where channel trees are used in routing and the trees are not static. The case for faulty nodes and energy depletion is considered where the topology of the network may change throughout the implementation to the network. In order to make the network to have a dynamic routing, the proposed channel assignment scheme is performed in a semi-dynamic manner. The proposed protocol consists of three phases; first, the neighbor classification phase, second phase is the channel initialization phase and the third phase is adaptive routing phase.

Graphene Nanoribbon (GNR) is considered as a forthcoming material for the next generation of nanoelectronic devices. The more exciting thing in GNR is that it shows considerable bandgap. Armchair GNR (A-GNR) is one type of GNRs which demonstrate semiconducting electronic properties. In this research, it has been observed that due to edge effect and thermal effect on A-GNR, the electronic properties vary. In this paper, the electronic properties like bandgap energy, carrier concentration, capacitance and fermi probability for a definite energy level have been analyzed by considering the above mentioned effect.

Now-a-days, the sales centres are using Digital Weighing Machines (DWM) for precision measurement of weight, acquisition of rate from keypad and computation of cost. The weight, rate and cost are shown on 7-segment bright display devices. The implementation of a DWM can be carried out using various types of hardware topologies and accordingly the cost varies. The FPGA based DWM is the most competitive one; but, the technology is beyond affordability of the small business houses due to very high initial capital investment for the design and fabrication of the FPGA chip. It is possible to realize a DWM of moderate cost using an ATmega32 microcontroller, which provides almost a single chip design particularly owing to its high-power (20mA) 32-IO lines, which can directly drive 7-segment display devices, ADC, and Keypad. In this paper, we have presented the design methodology of an ATmega32 based DWM, which has been prototyped and tested using RMCKIT.

The project aims at designing an earthquake monitoring and warning system that is capable of detecting earthquakes as well as warning people to take necessary precautions. This system will not only attempt to save human lives, but will also store the data for later use by professionals working at this sector. The objective of this project is to design a LabVIEW based control system by collaborating MEMS accelerometer sensor with Arduino microcontrollers in a ZigBee wireless network. The system also has telecom VAS capabilities to alert people and control machines. Existing earthquake systems are moreover designed for aftershock management and they hardly deal with real-time data. However, this system is mainly designed to react as soon as the sensor nodes come across a p-wave.

At present, a higher number of researches are being directed on alternative energy sources to supply power for modern life of today and the future. As the conventional sources of energy are diminishing day by day, one of the most promising sources is wind energy which can provide electrical power using wind turbines. The increase in the use of this type of energy requires greater consideration of wind speed, installation and especially the per unit cost of energy produced by wind turbines. This paper will discuss the feasibility of wind energy prospect in Bangladesh considering the wind speed at the particular representative coastal locations and also the wind turbine which can be used commercially. We also propose a 2MW wind power plant at `Parky Saikat, Chittagong'. For which the system and cost calculation is carried out by the `HOMER Energy' simulation software.

Free-standing tri-layer graphene shows stacking dependent band gap when external bias is applied. In this work, we have made an attempt to observe the electronic structure of tri-layer graphene with different stacking on Cu (111) substrate without applying any external bias. We have performed density functional theory (DFT) calculation and observe that band gap occurs and doping takes place due to the interaction of graphene-metal surface. We have also calculated density of states for different stacking systems. We observe that the band gap and doping of graphene on substrate largely depend on the stacking system and such study would be beneficial for material science as well as electronic industry.

Low frequency oscillation is a threat to the stability of interconnected power system. Proper identification of the low frequency oscillation is crucial. In this work continuous wavelet transform (CWT) with complex morlet wavelet is used to extract modal information of the power system oscillations. The modal information of the measured signal such as frequency and damping is determined from the magnitude and phase plot of the complex valued wavelet coefficients. The proposed technique is applied to the measured signal of a two area power system to detect inter area mode of oscillation and results are compared with Eigenvalue analysis method.

Semiconductor lasers often involve various noise and instability problems due to fluctuation of photon and carrier numbers. In this paper, we analyze the quantum noise, both intensity and phase, of semiconductor lasers operating in single mode. Direct numerical integration of the self-consistent rate equations has been used to overcome limitations of the small-signal analysis. Langevin noise sources for photon number and phase have been used to count fluctuations due to spontaneous emission and the process of carrier recombination. Rate equations are applied to 850-nm GaAs lasers. Fast Fourier Transform (FFT) has been used to calculate the frequency spectra of both intensity and phase noise. Noise characteristics for different injection currents have been demonstrated. Results show that both intensity and phase noise decreases as the injection current density increases and the linewidths were decreasing substantially with increasing injection current as well.
