A robust mean shift integrating color, GLCM based texture features and frame differencing[ ]


Mean shift is a kernel based widely used algorithm for tracking the location of object robustly. Classical mean shift uses color histogram to represent the object. However, the use of only color restricts the algorithm to track the object only in simple cases and it fails in complex situations like illumination changes, occlusion, and abrupt changes in the location of object. To improve the performance of mean shift, some authors have added some features to basic mean shift. As color based target representation is combined with texture-based target representation, based on spatial dependencies and co-occurrence distribution within interest target region for invariant target description, which is computed through so-scaled Haralick texture features, is an efficient mean shift for target tracking in some real world complex conditions. But it still fails, if there are some abrupt changes in the location of object. So a novel algorithm is presented in this work, which is robust to track the object in above mentioned complex situations. It is the combination of color and gray level co-occurrence matrix based texture features along with the use of frame differencing for abrupt motion changing target detection.

An Application Programming Interface Based Architectural Design for Information Retrieval in Semantic Organization[ ]


The World Wide Web (WWW) allows users to share the information or data from the large database repositories all over the world. In World Wide Web the data is increasing on internet day by day but small amount of data on internet provides us semantic access. It is a great need to have a framework to organize data structurally and in a fast way. The World Wide Web is used as the source of information. The purpose of this research is to make conceptual semantic scraping framework for fast and structured extraction of reusable information from one specific domain. There are many convenient applications that are playing important roles to facilitate users in a specific domain but are not fulfill the desires due to exponential growth of data over internet. It is difficult to retrieve information from unstructured data because of messy Hyper Text Markup Language (HTML) pages, cookies check, and data privacy and exponential growth and enormous size of Web sources. In this study, an API based framework for data handling is introduced that extracts the data from targeted sources, organize it semantically and provide it in a structured or tabular format. It makes the process of generating the query related to his/her topic very reliable and convenient.

Adsorption of Dichlorvos in aqueous solution onto Activated Carbon from Canarium Schweinfurthii Seed Shell[ ]


Activated carbons were prepared from the agricultural waste Canaruim schweinfurthii seed shell with zinc chloride (ZnCl2) and Phosphoric acid (H3PO4) as chemical activation agents. The activated carbons were prepared by carbonization at 300°C, 350°C, 400°C, 450°C and 500°C for 5, 10 and 15 minutes. The optimum conditions for activated carbon production were evaluated based on the determination of adsorption capacity of Dichlorvos. It was found that the maximum unit capacity for Dichlorvos was 39.42 mg/g at activation temperature of 300°C and activation time of 5minutes with zinc chloride as the activating agent. It was found that the optimum unit capacity for Dichlorvos was 39.08 mg/g at activation temperature of 300°C and activation time of 5 minutes using Phosphoric acid as activating agent. This study showed that both activated carbons produced with zinc chloride and phosphoric acid as activating agent can be utilized as effective matrices for Dichlorvos removal from aqueous medium.

Prediction of Mechanical Properties of Hybrid FRP Composite for Out-of Plane Transverse Loading Using Micro Mechanical Approach[ ]


The present research problem deals with the micromechanical analysis of a unidirectional continuous hybrid fiber-reinforced composite lamina. Three-dimensional models along with governing boundary conditions have been developed from the Representative Volume Elements (RVE) which are idealized as an array of square unit cells. The stress-strain relation in the finite element models takes place according to three-dimensional elasticity theory. The hybrid lamina consists of two different fibers of T-300 and S-GLASS materials, and epoxy matrix. The micromechanical analysis includes the evaluation of mechanical properties of the hybrid lamina at the fiber-matrix interface for perfectly bonded interfaces. In this phase of the work, the out-of-plane transverse Young’s modulus (E3), Poisson’s ratios (?31 and ?32) are determined for a hybrid lamina for different volume fractions of fibers. In this case, the lamina is subjected to uniform pressure load in the out-of-plane transverse direction of the composite lamina and no debond is considered at the fiber-matrix interfaces.

CHARACTERIZATION OF EFFLUENT FROM THE FUELS PLANTS AND ITS CONTRIBUTION TO THE OVERALL EFFLUENT CHARACTERISTICS OF KADUNA REFINERY[ ]


Effluent samples were collected from the Fuels Plants (CDU-1, NHU and CRU) of Kaduna Refining and Petrochemical Company (KRPC) as well as Waste Water Treatment plant and the Effluent Outfall to the environment. The physicochemical properties of the Effluents samples were determined using various analytical techniques based on American Society for Testing and Measurement (ASTM) methods. The metals (Mercury, Cadmium, Iron, Lead, Zinc, Copper, Vanadium, and Chromium) were determined using Atomic Absorption Spectroscopy (AAS) method. The study showed that the Conductivities, the Biochemical Oxygen Demand (BOD), the Chemical Oxygen Demand (COD), the Oil and Grease, Sulphide, Temperature and pH of the effluent samples from these fuels plants were higher than the NESREA acceptable standard. Heavy metals concentrations in the effluents samples were also determined. It was observed that mercury, cadmium and lead concentrations were higher than the NESREA limit in the samples from these plants, and therefore contributes heavily to the overall effluent characteristics of the refinery. It was recommended that the treatment of effluent samples for Conductivity, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Oil and grease, pH, Temperature, Sulphide, Mercury, Cadmium and Lead should start at the fuels plants where they are generated. This will reduce contaminants in the effluent at source which will in turn result to increase in efficiency and quality of treatment at the waste water treatment plant.

Small-scale kinetic Alfven waves in the presence of warm and cold magnetized plasma in plasma sheet boundary layer – kinetic approach[ ]


Kinetic Alfven wave has been studied by kinetic approach to evaluate the dispersion relation and damping- rate of small scale Alfven wave in homogenous plasma in both cases (warm and cold electron limit) in plasma sheet boundary layer. Kinetic effects of electrons and ions are included to study kinetic Alfven wave because both are important in the transition region. It is found that the ratio ? of electron thermal energy density to magnetic field energy density and the ratio of ion to electron thermal temperature (Ti/Te) affect the dispersion relation and damping-rate in both cases (warm and cold electron limit). It is predicted that higher k??i >1 are more effective for the bi-Maxwellian distribution, here k? is perpendicular wave number and ?i is the ion gyro radius. The method may be suitable to deal with the PSBL, where particle acceleration is also important along with wave emissions.

Bioremediation of Chromium (VI) In Electroplating Industrial Effluent[ ]


Heavy metal Cr in +6 oxidation state, introduced from various kinds industrial effluent is extremely toxic, carcinogenic and mutagenic in nature. Its direct discharge can contaminate the soils, ground water, sediments and surface waters and creates serious risk to environment which requires immediate attention for getting eco friendly and economical solution for effluent treatment containing Cr(VI). Large quantities of biomaterials have shown efficient uptake of heavy metals as a result of various metabolism for the removal of metals. Chromate reducing bacteria (CRS),Burkholderia sp (CRS-Y2) and Kocuria turfanensis (CRS-R), Microbes-cell and extracellular enzyme secreted by microbes isolated from discharge site of effluent, can be used to achieve bioremediation of toxic chromium(VI).

Rejection of Common-Mode Voltages in ECG Signal by Removing the Ground Electrode[ ]


Common mode voltages rejection in ECG signal becomes a crucial issue. The identification and minimization of these common voltages is necessary to acquire such signal since its level is low (few millivolts) compared to these undesirable common voltages generated by the surrounding environment. We investigate different sources of common voltages coupled to an ECG signal and analyze techniques to reject and mitigate their effects. We propose the elimination of the ground electrode and study its efficiency to reduce common-mode voltages and improve the rejection ratio of the bioamplifier. We provide a qualitative ECG signal acquisition with a sophisticated analog front-end architecture resulting on an accurate ECG signal detection and an improved Common-Mode and Isolation-Mode Rejection: CMR and IMR.

Design and Development of Low Cost Nursery Seeder for Cinnamon-Cinnamomum zelanicum[ ]


Proper spacing reduces the competition between plants to acquire nutrients, water, space, light, etc. Plant spacing uniformity begins with the uniformity of seed spacing. However, when practicing conventional manual seeding, maintaining of uniformity distribution of cinnamon seeds in nursery poly bags causes serious difficulties. Therefore, this study developed a cinnamon nursery poly bag seeder to avoid uneven distribution of seeding in conventional seeding practices with acceptable efficiency and low cost. Accordingly, the final prototype was developed by adopting pneumatic type seed metering system.The results revealed that the average time taken for seeding a single nursery poly bag by the conventional manual seeding and the developed seeder was 11.9s and 2.9s where the saving of time with 74.9 % higher. Moreover, the developed seeder was found to be accurate in maintaining even seed distribution within the polybag. Thus, the developed pneumatic type cinnamon poly bag seeder can be proposed as an appropriate tool to replace the existing tedious process of manual seeding in cinnamon cultivations.

OPTIMAL LAND ALLOCATION IN KRISHNA DISTRICT WITHOUT CIRCULAR ECONOMY IN CRISP ENVIRONMENT[ ]


The agricultural sector’s performance determines overall economic growth, trade expansion, and increased income-earning opportunities. Agriculture planning depends on several resources like availability of land, water, labor, machinery and capital. Land resources have great importance for supporting social and economic development. Due to the limited land resources, determining how to use land rationally and efficiently has been one of the key issues. Agricultural planning problems generally involve multiple goals such as maximizing production, profit, ecological benefit and minimizing expenditure, fertilizer consumption, environmental pollution, etc. These goals are conflicting in nature and it is not possible to maximize or minimize all goals simultaneously. In this article a fertile land in a particular district where the land is very fertile is considered and studied for optimal allocation.
