Abstract:

World Wide Web (or simply web) is a massive, wealthy, preferable, effortlessly available and appropriate source of information and its users are increasing very swiftly now a day. To salvage information from web, search engines are used which access web pages as per the requirement of the users. The size of the web is very wide and contains structured, semi structured and unstructured data. Most of the data present in the web is unmanaged so it is not possible to access the whole web at once in a single attempt, so search engine use web crawler. Web crawler is a vital part of the search engine. It is a program that navigates the web and downloads the references of the web pages.Search engine runs several instances of the crawlers on wide spread servers to get diversified information from them. The web crawler crawls from one page to another in the World Wide Web, fetch the webpage, load the content of the page to search engine's database and index it. Index is a huge database of words and text that occur on different webpage. This paper presentsa systematic study of the web crawler. The study of web crawler is very important because properly designed web crawlers always yield well results most of the time.

Abstract:

A small size cassava chips batch dryer was designed, constructed and evaluated at the Department of Agricultural and Bio-Environmental Engineering of the Federal Polytechnic, Ado Ekiti. The system consists of the following components: frame, drying chamber, electric heater, blower, drying trays and controlling unit. The system works on a heating coil of 500watts as the source of heat and a circulation fan that runs at 60 watts. The compartment was holed up at a chimney to allow for escape of moist air. The cost is moderate and affordable..

Abstract:

The atomic structure of platinum nanoparticles (Pt NPs) loaded on carbon black (CB) particles was investigated using high-resolution transmission electron microscopy (HRTEM). The Pt NPs were inhomogeneously strained and approximated as monoclinic structures. No correlation was observed between the monoclinic lattice parameters and the size of Pt NPs. About 80 % of the Pt NPs were compressively strained, and about 20 % of the Pt NPs were expansively strained. Side-view HRTEM analyses of Pt NPs were performed for specimens milled by a focused ion beam apparatus (FIB). The (111), (100), and (110) facets of the Pt NPs were observed to be adhered to CB particles. The frequency of Pt NP-CB adhesion interfaces decreased in the order of (111), (100), and (110) facets. This order was consistent with the (111), (100), and (110) planar packing fractions of Pt, the observed frequencies of (111), (100), and (110) facets of Pt NPs, and the (111), (100), and (110) surface energies of Pt. Further, variation of (111) interplanar spacing of Pt NPs on CB particles was measured as a function of azimuth angle of the (111) planes, and no correlation was observed between the variation of (111) interplanar spacing and the azimuth angle

Abstract:

Assessment of Land use/land cover changes mapping is one of the important task for watershed planners and researchers. The changes in LULC map provide the information about anthropogenic activities over a period of time in the region. In this context, the paper is reveals that, using multi temporal satellite data sets used of years 1989, 2001 and 2009 (Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+)) and applied Normalized Differenced Vegetation Index (NDVI) and change detection method using software's to know the spatial and temporal distributions in the study area. The temporal results represented that increased and decreased trend of spatial patterns in water bodies, agricultural lands, fallow lands and barren lands. These studies are also helpful to researchers and planners, reasons behind the changes in land cover to land uses, assess hydrological parameters impacts on study area previously and present, assess climate changes impacts in the feature of the study are while using any hydrological models.

Abstract:

Agriculture is one of the oldest professions but the development and use of machinery has made the job title of farmer a rarity. Instead of every person having to work to provide food for themselves, smaller portion of our population today works in agriculture, the smaller portion provides considerably more food than the other can eat. The basic technology of agricultural machines has changed little in the last century with the coming of the Industrial Revolution and the development of more complicated machines. In this work it is proposed to design and fabricate the automatic mechanical cutter by using crank and slotted lever mechanism, for cutting agricultural products like sugarcane for cultivation and also used to cut wooden pieces of required size for boilers. The equipment makes the use of crank and slotted lever mechanism with one slider to couple with an electric motor..

Abstract:

In mobile robotics applications, the existence of noise measurement may impact on the performance degradation. The noise measurement of the sensor is produced due to several reasons, such as low specification, external signal disturbances and the complexity of the measured state. Therefore, it should be avoided to achieve the good control performance. One of the solution is by designing a signal filter. In this paper, a new digital signal-processing method for ultrasonic time-of-flight (TOF) estimation is presented. The method applies the discrete extended Kalman filter (DEKF) to the acquired ultrasonic signal in order to accurately estimate the shape factors of echo envelope as well as locate its onset. It is so possible to assure reduced bias and uncertainty also in critical TOF measurements, such as those involving low signal to noise ratio (SNR) as well as severe distortion of echo shape. A number of numerical tests are conducted on simulated signals with the aim of highlighting the good performance of the method when operating in critical conditions.

Abstract:

This study aimed to use zeolite and blast furnace slag (BFS) as main raw materials in the production of autoclaved aerated concrete (AAC). AAC is a light building material obtained by bringing the material of silica sand, cement, gypsum, lime and pore-forming agent together and hardening it in autoclave. In this study, instead of silica sand, samples of AAC were produced using zeolite and BFS. Experimental measurements were carried out to determine the physical, mechanical and thermal properties of the AAC samples. The microstructural investigations were carried out using SEM and XRD technique. According to the obtained results, it has been found that the physical and mechanical properties of the series produced with BFS are better than zeolite. Thermal conductivity coefficients of 630 kg/m3 bulk density were determined as 0,127 W/mK in series produced with BFS. This value was found to be 0.139 W/mK at the bulk density of 550 kg/m3 in the series produced with zeolite..

Abstract:

On the basis of the first law of thermodynamics, an analysis of the orientation of structural interactions was carried out. In the systems in which the interaction proceeds along the potential gradient (positive work), the resultant potential energy is found based on the principle of adding reciprocals of corresponding energies of subsystems - there is a corpuscular mechanism. In the systems in which the interactions proceed against the potential gradient (negative performance) the algebraic addition of their masses, as well as the corresponding energies of subsystems is performed - there is a wave mechanism. Act of quantum action expressed via Plank's constant is narrowed to the energy equilibrium-exchange redistribution between the corpuscular and wave processes........
