Abstract :

Ancient language Font Recognition is one of the Challenging tasks in Optical Character Recognition and Document Analysis. Most of the existing methods are for font recognition make use of local typographical features and connected component analysis. In this paper, Ancient language font recognition is done based on global texture analysis. Ancient language characters are different from current  century’s Ancient language character. This paper concentrates on the century identification of ancient language characters and converting them into current century’s form using MATLAB. Recognition of ancient language hand written characters from inscriptions is difficult. In this paper, a method for recognizing Ancient language characters from stone inscriptions, called the contour-let transform, which has been recently introduced, is adopted. From the previous research works, it’s noticed that Wavelet transforms are not capable of reconstructing curved images are perfectly. The contour-let transform offers a solution to remedy to this insufficiency. Contour-let transform is a 3D approach technique where as wavelet transform is a 2D technique. The characters from the input image are recognized through the clustering mechanism. Further the noise is present in the image is removed by fuzzy median filters. Neural networks are been employed to train the image and compare the data with the current century’s character. hence a more accurate recognition of Ancient language characters from stone inscriptions is obtained.

Abstract :

This paper proposes a MATLAB algorithm which can perform X-ray Fluorescence (XRF) spectrum analysis using a type of calibration method known as fundamental parameters (FP). This calibration method is unique because it uses the theoretical relationship between measured X-ray intensities and concentrations of the elements in a given sample. This is different from an empirical approach which uses known sample spectra and known composition and results to obtain results. The fundamental parameter approach is more complex compared to the empirical approach as there are different factors involved in the calculation of these parameters. In this paper, An XRF spectrometer (X-MET8000 by Oxford Instruments) was used for performing experimental gathering of sample spectra. Sample spectra for various pure elements and alloys were obtained and used as an input to the proposed MATLAB algorithm. The MATLAB algorithm uses the FP approach to qualitatively and quantitatively identify the elements present in the tested spectra. The proposed algorithm was able to successfully identify the elements present in the sample as well the elemental composition by means of the FP approach. This algorithm was also compared with results from another similar algorithm that was used to identify alloys by empirical means. The results obtained which include the elemental composition and the present elements is then compared with standardised known test samples of various pure elements and alloys for verification as a measure of accuracy and validity of the MATLAB algorithm which was found to be accurate to within 0.6 percentage points. The working speed of the MATLAB algorithm was also tested experimentally and was observed to be able to process 11-82 samples per second depending on the mix of the sample and type of analysis.

Abstract :

Strengthening of reinforced concrete members by externally bonded fiber reinforced polymers (FRP) sheets or plates has been increasing in recent years due to the beneficial characteristics of being non-corrosive and generally resistant chemicals, high strength to weight ratio, and non-magnetic and non-conductivity of composite materials. The experimental results showed that better performance of the strengthened sections with GFRP could be achieved in terms of ultimate load, crack control, and stiffness. Application of GFRP to strengthen underground tunnels is one of the prime applications due to the severe environment, which the concrete is exposed. Repair work of underground tunnels such as "Ahmed Hamdi Tunnel under Suez Canal "or" El-Salam Tunnel under Suez Canal" is carried out mainly to strengthen the primary lining of the tunnel due to any defects or cracks. Experimental program contain four shapes of concrete tunnel "Circular section, Elliptical section, Egg-Shaped section and Horse shoie section"  to investigate of the research work showed that the procedure described in this paper is stable, fast in convergence and effective for tunnels applications.

Abstract :

Alkali Carbonate Reaction (ACR) may occur in concrete having dolomitic aggregates and will have deterrent effects on the concrete structures. So, the investigation becomes necessary before its application in concrete. As we know that the occurrence of ACR will depend upon the mineralogy of the rock. So, in this paper, along with the ACR test (by rock Cylinder Method), X-ray Diffraction (XRD) is also done on dolomitic rock from five different quarries of Northen India. Through XRD, it is found that the mineralogical composition of the samples from five quarries were different. The analysis of RCM results revealed that the percentage change in the length varied from -0.0368 to -0.974%. When the two studies were brought together, it is found that the percentage change in length of the rock cylinder (through Rock Cylinder Method) is proportional to the percentage of Calcium Magnessium Carbonate Dolomite present in the rock.

Abstract :

Zinc oxide and Mn doped zinc oxide nanoparticles were synthesized by wet chemical technique using zinc acetate dehydrate as a precursor. Highly stable pure and 0.2, 0.4, 0.6, 0.8, 1.0 and 5.0 weight percentage Mn doped ZnO nanoparticles have been prepared at room temperature. The detailed structural properties were examined using X-ray diffraction pattern (XRD) which revealed that the synthesized nano particles are well crystalline and possessing wurtzite hexagonal phase. The dielectric studies were carried out. The present study indicates that the polarization mechanism in the nano particles considered is mainly contributed by space charge polarization. It can be understood that the space charge contribution plays an important role in the charge transport and polarizability in all the  systems considered in the present study. The dielectric constant, dielectric loss, AC conductivity and DC conductivity increases with increase in temperature.

Abstract :

This paper introduces an application of the use of electromagnetic push-pull mechanism to the solution of mathematical programming problems. The algorithm used is similar to the methodology used to solve “Travelling Salesman Problem” using a population based algorithm simulating the push-pull mechanism of electromagnetic theory, which was originally applied to unconstrained optimization problems in continuous space. The charge (objective function value) of each solution point in feasible population applies attraction and repulsion force on the points in population and moves the objective function towards optimality, i.e. to point with highest pull force. Two different versions of TSP based EM mechanism is used to find optimum political districts, where districts formed must be compact and contiguous, while each zone have almost equal population. The algorithms are tested to redraw borders of the fifty polling zones of North Cyprus.

Abstract :

Image segmentation is one of the most important and most difficult low-level image analysis tasks. Automatic target recognition (ATR) often uses segmentation to separate the desired target from the background. Fuzzy c-means (FCM) algorithm is one of the most popular fuzzy clustering techniques because it is efficient, and easy to implement. Fuzzy clustering is a main problem which is the subject of dynamic research in several real world applications. However, FCM is sensitive to initialization and is easily trapped in local optima. In this paper, DPSO is used to escape from local optima and to determine the global optima which are calculated on comparing with single swarm and similar set of swarms, operating on the test problem obtained for PSO.

Abstract :

Microgrid is an aggregation of distributed generators (DGs) and energy storage systems (ESS) through corresponding power interface, such as synchronous generators, asynchronous generators and power electronic devices. Without the support from the public grid, the control and management of an autonomous microgrid is more complex due to its poor equivalent system inertia. To investigate microgrid dynamic stability, a small -signal model of a typical microgrid containing asynchronous gener-ator based wind turbine, synchronous diesel generator, power electronic based energy storage and power network is proposed in this paper. The small-signal model of each of the subsystem is established respectively and then the global model is set up in a global reference axil frame. Eigenvalues distributions of the microgrid system under certain steady operating status are identified to indicate the damping of the oscillatory terms and its effect on system stability margin. Eigenvalues loci analysis is also presented which helps identifying the relationship among the dynamic stability, system configuration and operation status, such as the variation of intermittent generations and ESS with different control strategies. The results obtained from the model and eigenvalues analysis are verified through simulations and experiments on a study microgrid system.

Abstract :

Leo satellites are one of the most promising communication and plays important role in delivering high quality of data within the range of 500-1500 km. Leo satellites are for broadcasting internet and connecting remote places at the time of natural calamities. The Leo satellites are preferred due to less propagation delay and packet loss compared to Geo satellites. Generally the communication is done in indirect format means connecting the original satellite through intermediate ones. This leads to delay in process. To reduce that delay we are going to provide a direct communication to original satellite by knowing the co-ordinates of the particular satellites. In order to find out the co-ordinates of the satellites we need the routing protocols. The routing protocols of the satellites are based on the quality of service, multicast and multipath. By using the algorithms like ATM and switching, satellite network topology we are going to provide a direct communication with less propagation delay. The multimedia applications and live transmissions cannot bear packet loss, jitter, and timeliness and need the high throughput through the transmission. We did a survey for the best routing protocol for satellite networks.

Abstract :

It is the well known fact that alkali aggregate reactions are one of the predominant causes of concrete deterioration. Alkali Silica Reaction (ASR) is a chemical reaction between the alkalis in Portland cement and certain types of silica minerals present in some aggregates. ASR is very harmful for the concrete structures and reduces the service life of the structures. To retard ASR rate, the process of   dilution of alkalis by increasing silica content using Portland Pozzolana Cement or Portland Slag Cement or some mineral additives like fly ash, Micro Silica, Metakaolin, etc., are very effective. The aim of the current study was to determine the effectiveness of Portland Pozzolana Cement (PPC) in mitigation of ASR expansion while used in place of Ordinary Portland Cement (OPC) for the aggregate sample of five different quarries. The outcome of the study is presented in this paper which is effective in controlling ASR.

Abstract :

The performance of any type of pavements is more contributed on sub-grade soil strength. Many stabilizing techniques and materials were used to increase the strength of sub-grade soil among different natural and artificial geotextile material. Jute is one of the natural abundant resource materials many studies were carried out on jute geotextile on embankment slope protection and embankment construction and drainage design. Jute material is used in reinforcement of soil layer in pavement design. Several case studies in field showed that the strength of Jute Geotextile typically reduced about 60 to 70 percent after lying embedded in estuarine soil for around 18 months. Jute is bio-degradation material in this studies the span of JGT can be increased by spraying bitumen on the jute and reinforcing the soil layer and structurally evaluating the stresses and strains under standard axle load condition 8T another method can adopt by using the polythene sheets like sandwich layer to increase the span and strength of jute fiber and sub-grade strength of CBR value.  Research studies will carried on sub-grade soil to increase the CBR value by using jute with bitumen coated/polythene sheets. Some experimental studies had been conducted on clay soil (CI) and results were not reliable for heavy compaction. Principal application of JGT is to reduce the pavement thickness layers and Appropriately designed woven JGT when placed on a road sub-grade enhances its bearing capacity (expressed as CBR %).The phenomenon is the result of the functions of separation and filtration performed by an appropriately designed woven JGT laid on the sub-grade. Consolidation of soil is a protracted process. Normally the range of enhancement of CBR of a sub-grade treated with JGT is 150% to 300% of the control value.

Abstract :

In survey sampling, accuracy of point estimates are assessed using variance estimates. Variance estimates becomes difficult when we have non-linear point estimators or complex sampling designs. The jackknife has been suggested as a useful cutoff resampling technique to overcome these difficulties. The approximation of sampling relative error for the total in stratified sampling without replacement from finite populations will be reviewed in this paper. And a general jackknife within each stratum estimator of Cao, R. et al (2013) is derived.

Abstract :

Paper is devoted to the area of processing of physical signals and data or artificial perception. The incoming data are presented in the form of defined sum of two unknown functions, spaced on finite carrier. Practical examples of the functions searched for can be presented: (a) by very closely spaced two atomic spectrums of radiation; (b) by the output signal of some telescope, scanning two point-like sources with angle distance between each other much less, than the angle width of main petal of telescope's directivity pattern. So the presented result can be classified as some case of the known problem of superresolution. It is shown, that two functions of tandem (mutually overlapping each other) can be reconstructed separately by using only three it is correct chosen numbers. The class of functions (and their tandems), which are overlapping each other and allows single reconstruction of both searched functions and also conditions of the correctness of the decision are formulated. The method of separation of two functions had been tested numerically on the variety of typical practical examples. The stability of suggested numerical procedure is confirmed in the presence of uncorrelated errors of measurements and calculations at each point of tandem.

Abstract :

Elephant Foot Yam was blanched at 80°C for 4 min in hot water and exposed to microwave treatment under different microwave power ranging from  300 W to 900 W and exposure time (1, 1.5 and 2 min) and then dried in convective dryer at 60°C to study their effect on microwave assisted convective drying characteristics. Drying time, average drying rate, effective moisture diffusivity, activation energy and rehydration ratio were various factors studied. Increased in microwave power and exposure time increased drying rate and decreased the drying time. The whole drying took place in falling rate period only. Midilli et al. model was found to describe the drying behaviour of elephant foot yam most precisely (highest R2 = 0.9996; least RMSE = 0.0051). The effective moisture diffusivity values ranges from 4.2 × 10-10 to 1.1× 10-9 m2/s and activation energy from 3.14 to 4.48 W/g. From storage study and sensory evaluation with quality in terms of protein, total sugar, ash and oxalate content was found to be acceptable in all drying treatments. Based on oxalate content and drying characteristics, exposure of 900 W microwaves for 2 min followed by hot air drying at 60°C was found to be most acceptable.

Abstract :

The possibility of constructing new kinds of energy-generating machines by making use of the magnetic, buoyant, and electrostatic forces has been explored. A simple device capable of extracting energy from the permanent magnets has been fabricated. It makes use of both the attractive and repulsive forces between the pole-pieces of an electromagnet and those of a set of permanent magnets in sequential order to impart a unidirectional motion to a disc rotor along the rim of which pole-pieces of the permanent magnets are fixed pair-wise with regular spacing. The possibility of energy extraction by making use of antigravity forces has been demonstrated by another working device. The working of the contraption is based on the buoyant forces experienced by a float with the rise of water level in a tank, and translating this movement of the float into useful work through a lever and a crank-shaft system. Charging metal plates through electrostatic induction and subsequent discharging of the charged plates to generate electricity has been the basic principle of the third type of energy generating unit. The construction and working of these devices as well as their limitations and future prospects are discussed in this paper.
