DETERMINING INFLUENTIAL USER(S) IN ONLINE SOCIAL NETWORKS[ ]


In today’s world online social network (OSNs) are exclusive social and web portent affecting perceptions and behaviours of their users and helping them to maintain/create social presence. It is remarkable to analyze the growth and evolution of online social networks where either we consider the marketing strategy or new services being offered, also from a scientific viewpoint, since their erection and evolution may share similarities with tangible social network. Several techniques for analyzing social networks have been developed, to gauge quantitative properties (e.g., defining metrics and measures of fundamental characteristics of the networks) or qualitative aspects (e.g., studying the attachment model for the network evolution and the link prediction problem). However, online social network analysis poses novel challenges both to computer and Social scientists.

TREND OF NEAR-SURFACE VELOCITIES, FROM COASTLINE TO SWAMP ZONE OF THE SOUTHEASTERN NIGER DELTA, NIGERIA[ ]


Near-surface velocities are made up of the velocities of the weathered layer, and that of the underlying refractor or consolidated layer. The trend of this group of velocities from the coastline axis to the swamp environment in the transition zone of the Niger delta shows a decreasing behavior with magnitudes ranging from 934m/sec to 1140m/sec. The near-surface sediments of the Niger Delta, are characterized by unique irregularities in the rock-type, heterogeneous in pore-spaces and compaction, irregular geomorphology or topography as well as sediment densities and velocities. The propagation velocity in this medium is influenced by the looseness of the sediments within the weathered layer, also called the “Low-Velocity-Layer”.

SEISMIC CROSS SPREAD TECHNIQUE OF GEOPHYSICAL PROSPECTING AND IMPACTS OF PERMIT PROBLEMS IN SOME PARTS OF AFRICAN REGIONS[ ]


The principle of straight and wavy lines maintained in cross spread technique from the origin or start of seismic lines to the end of the lines enhances transportation or traffic within the spread. The uninterrupted movement and easy roll along of recording swaths are absent in the brick-wall method of seismic data acquisition, as the discrete segments of source lines terminate between receiver lines. The cross spread technique is based on orthogonal geometry and is suitable to acquire wide-azimuth data. Each intersection of a source line and a receiver line forms the center of a cross-spread. The dense sampling of the sources along the source line and of the receivers along the receiver line creates a dense single-fold areal coverage. The wide spread accesses created by seismic lines in the technique opens the doors to third party disturbances to production recording.

Utilization of Solar Energy as a Thermal Energy Storage System in Palestine[ ]


Energy and water are vital items for the development of any nation. People of Palestine are living in critical situation regarding their needs of energy and water due to the lack of fusel fuels and shortage of water and other conventional resources. In addition to the continuous Israeli occupation, which has been about seven decades. It controls the water and energy needs and hinders the development policies and plans of both the private and governmental sectors. This has reflected on the socio economic development of the whole population of the country. Despite all the occupation obstacles, the Palestinians are taking every possible chance to overcome these obstacles and utilize their natural resources. In this paper, the scope of utilizing a thermal energy storage system which uses sand as a storage medium which is readily available in most regions in Palestine is very promising in fulfilling part of the energy needs of the country. The use of this type of renewable energy will reduce the green gases emission and results in a cleaner environment. Furthermore, a system for heating and cooling buildings using sand as a storage medium is also presented and discussed.

Effects of Gradation on Hydraulic Conductivity Properties of Compacted Laterite Soil Liner: A Review[ ]


This paper presents the recent review on the effects of gradation on hydraulic conductivity properties of compacted laterite soil liner. The distribution of different grain sizes affects the engineering properties of soil such as compressibility, shear strength, and hydraulic conductivity. It is observed that there are variations in hydraulic conductivity values in laterite soils from various researches around tropical countries of the world. Hydraulic conductivity varies from 4.36×10-3 m/s to 4.7×10-11 m/s relative to fine contents ranging from 1.3% to 69% and coarse contents ranging from 31% to 98.7%. Generally, there is no clear trend established for effects of gradation on hydraulic conductivity properties of compacted laterite soil liners. This is because laterite soils with less than 50% fines content cannot be used as liner or hydraulic barriers because their hydraulic conductivities are less than the minimum requirement of 1 × 10-9 m/s. It is anticipated that with logical understanding of the effects of gradation on hydraulic conductivity properties of compacted laterite soil it will serve as a guide in the design of hydraulic barriers for engineered sanitary landfills in tropical countries around the world.

Image Mosaicing using Feature based technique[ ]


The automatic construction of large, high resolution image mosaics is an active research area in the field of photogrammetry, computer vision, image processing and computer graphics. The need for developing a technique which does the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image is because the human visual system has a field of view of around 135 x 200 degrees, but a typical camera has a field of view of only 35 x 50 degrees. To overcome the barrier of a bounded field of view, to expand one’s visual perceptive arena, Image Mosaicing technique has been developed. It is a field of study in the discipline of Computer Vision whose study is devoted to discovering algorithms, data representations, and computer architectures that embody the principles underlying visual capabilities. It thus is a multi-disciplinary field of science and technology that depends on information taken from the images. It aims at building artificial systems to simulate the seeing sense of living beings. The mosaiced image (stitched image) of various images of the same scene is obtained by following a sequence of steps. The image is first analysed and all the local features(corners) are detected by employing feature detection algorithms. Most efficient algorithm being Scale Invariant Feature Transform(SIFT). These local features detected are matched and the overlapped portion of the images of the same scene is located. These images are then aligned according to the planar coordinate transformations. After appropriate alignment, excess portion of the overlapped region is removed with the help of a procedure known as homography using RANSAC algorithm. Later to obtain a seamless view of the scene captured without the stitched region being visible is obtained by blending both the images. This process flow results in a high resolution well stitched image output.

RAPID DETECTION OF SOIL ORGANIC CARBON USING SHORTWAVE NEAR INFRARED (SW-NIR) SPECTROSCOPY[ ]


Soil organic matter content is a primary indicator of quality over measuring soil organic carbon (SOC). Demand has been created for quick and real time multiple analysis methods for SOC instead of available laborious, time consuming and expensive methods. There are developed Near Infrared Spectroscopy (NIR) methodologies for detecting SOC, however imply either expensive full scale NIR instruments or considerable work on sample preparation. There are attempt in narrow range vehicle mounted NIR detections in precision agriculture on the go mode SOC very low accuracy. This study develops a rapid method for the detection of SOC for laboratory scale. Soil samples(n=144) were collected from a range of sites at Mapalana research farm, University of Ruhuna in three different depths including 3 replicates from each depth. Seventy-two air-dried, sieved and finely ground soil samples were prepared in conventional dry sample presentation method. Four spectra per sample were taken by holding them into sample cups. Soil samples, saturated with distilled water were kept for 30min and similar process were followed for new wet sample presentation approach. Direct probe NIR Spectrometer FQA-NIR Gun (588-1100 nm) (Shibuya Seiki, Hamamatsu, Japan), was used to acquire NIR reflectance spectra. Standard Walkey-Black method was used to detect the organic carbon contents of spectra acquired soil samples as the respective reference data to validate the approach. For both wet and dry soil sample types, Partial Least Square (PLS) regression models were developed to predict the SOC. The validation results of both experiments were successful for the prediction of SOC where 0.95 of R2 and 0.248 of SEV for dry sample test and 0.91 of R2 and 0.245 of SEV for new wet sample approach. Sample preparation time and procedures were substantially reduced by the newly introduced wet method (30 min) when it is compared to the conventional spectroscopic methods (24 hrs). Average spectra investigation shows that 770 nm was strongly correlated with the SOC which could possibly be employed in further simplified instrumentation. The research revealed that the potential of using NIR technology as a nondestructive and rapid detection method for soil organic carbon with quick multiple field level detection facilities.

An Implementation of a Low Cost Three-Phase Automatic Power Changeover System with Over and Under Voltage Protection[ ]


This work discusses the design and implementation of a microcontroller based three-phase automatic changeover system for three different power supply sources using solid state relays. A microcontroller is used to monitor these three different power sources which are processed and connected to its inputs. The microcontroller places priority on the sources in the following order: public power supply, inverter, and generator. The microcontroller also checks for high/low voltages on each phase of the selected supply source. According to the input the microcontroller receives, relay switches are driven in order to maintain uninterrupted power supply to the load. In the event of failure of a supply source the load gets supply from the next available source in order of the stated priority. The current source of supply is displayed on a liquid crystal display (LCD), together with other vital information about the operation of the system. This changeover system is a standalone type that requires minimal maintenance interventions. The project can be further enhanced by including other sources, such as wind power, and then taking into consideration for use the best possible power source whose tariff remains lowest at any moment.

Oxy-hydrogen fuel as supplement for gasoline vehicles using Dry cell Generator[ ]


Fuel deficiency is the biggest concern hovering the 21st century automobile manufacturers and developers. Gasoline run vehicles are abundant at present and this affects the reservoirs and results into its depletion. The consumption of this fuel is greater than it being replenished, thus research and development have been channelized towards discovering a possible replacement. Oxyhydrogen, being the byproduct of pure water is the supplementary fuel found to sustain with gasoline and improve performance of the engine system. Hydrogen gas being highly combustible can’t be stored. Thus a system in which variable onboard production by varying current and usage of HHO gas has been devised. A controlled electrolysis of pure water in a compact hard polymer fabric material, using stainless steel plates as electrodes accomplishes the generation of HHO gas. Presence of HHO ions, traces of water and ionized oxygen particles, makes the combustion cleaner and faster. This also reduces hydrocarbon emission and keeps the engine cleaner due to better combustion cycle. This is a safe fuel, a cheaper alternative and the results compliment the current automobile production.

Performance Evaluation of CognitiveRadio Network under different pathloss models using frequency range of 1900 and 2100 MHz[ ]


The correct detection of the presence of licensed user (Primary user) is the most essential requirement of Cognitive Radio Network (CRN). Otherwise the PU will face jamming signal from unlicensed user (Secondary User) and therefore will not be able to transmit. At the same time if a PU is not in transmitting mode but SU senses the presence of PU in transmitting mode then the SU will stop transmission even though the frequency band is free to use. In this situation, different path loss models incorporating with different fading channels have been proposed previously to measure the performance of CRN. Fading is generally a signal loss due to sudden alteration in channel response. In this paper, the aim is to evaluate the performance under different types of fading condition (such as Rayleigh, Nakagami-m, Weibull and Normal) with the incorporation of different types of path loss models such as Lee's path loss Model, COST-231 Walfisch Ikagami Model and ECC-33/ Hata Okumura Extended Model along with MRC and Selection combining Scheme under frequency ranges of 1900 MHz and 2100 MHz as this range is well suited for 4G technology.

A Hybrid model for Named Entity Recognition in Biomedical Text[ ]


The phenomenal growth of medical information raises the need for mining the knowledge from biomedical text. Majority of biomedical information exists in unstructured text form. Named Entity Recognition (NER) from biomedical text is one of the basic tasks whose purpose is to recognize the name of some specified type of biological entities such as proteins, DNAs, RNAs, cells etc. Several attempts were made by the researchers to develop techniques for identification of named entities from biomedical literature. These methods are broadly classified into three categories such as, heuristic rule-based, dictionary-based, and statistical machine learning-based. But each approach has a drawback of either performance or complexity. This paper introduces a framework for Named Entity Recognition system in biomedical text that had shown improved performance and complexity. The foremost task of the framework is to identify and classify biomedical entities into one of these five classes, namely DNA, RNA, protein, cell-line and cell-type.

STUDY OF CRUSHED DOUM PALM SHELL AS PARTIAL REPLACEMENT OF COARSE AGGREGATE IN CONCRETE[ ]


This paper highlights the effects of replacing crushed granite (CG) aggregate commonly used in concrete with crushed doum palm shell (CDPS) on the workability, strength and density of concrete. Physical and Mechanical properties of CG and CDPS were determined and compared. It was found that, CDPS has higher water absorption value compared to CG while CG had a reatively higher aggregate impact value and specific gravity compared to CDPS. Furthermore, the compressive strength, workability and density of concrete containing 0, 5,10, 15, 20 and 25% of CDPS as replacement to CG in concrete with a mix ratio 1:2:4 and a water/cement (w/c) ratio of 0.55 was studied. A total of ninety concrete cubes of sizes 150 x 150 x 150 mm2 were casted, cured in water for 7,14 and 28 days after which compressive strengths and bulk densities of the cured cubes were determined. The result of the tests indicated that the compressive strength of concrete as well as the bulk density of concrete decreases as the percentage of the CDPS increases in the concrete mix. However, the workability of the concrete mix was found to increase up to a maximum value corresponding to 10% replacement of CG with CDPS after which it progressively decreased.

An Invertible Image Data Hiding Based On Contrast Enhancement[ ]


Data hiding is the art and science of communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. Reversible Data Hiding (RDH) is usually used to hide a piece of data into an image to produce a marked image. RDH is used widely in the field of signal processing to provide security to these images from the intruders. In addition, to evaluate the performance of RDH with PSNR, here the focus is on the contrast enhancement of the image. The data is embedded in the image, such that the data and image are completely recoverable. The highlight of RDH is that it gives back the original image after the data is being extracted from the marked image. It has been found that, by embedding considerable amount of data into the image, the contrast of the image is being enhanced. Many RDH techniques have been developed. Different RDH algorithms have their own merits and no single approach is optimal and applicable to all cases. To increase the embedding capacity, the equalization process is repeated. Along with the message bits, the side information is also embedded in the host image for the complete recovery. By adding the considerable amount of data into the image, the brightness of the image is increased. Improving the algorithm on the color and video will be the future work.

THE EFFECTS OF HYPERTENSION (HTA) IN PROGRESS OF CHRONIC RENAL FAILURE[ ]


In the past 20 years, doctors have clearly shown that antihypertensive therapy is very effective in reducing the incidence of myocardial infarction and stroke. However, little is known about the effects of blood pressure reduction in the end of renal disease stage (ESRD). Data from large clinical studies have clearly shown that patients with hypertension have an increased risk of developing ESRD.Black men and women with hypertension are at greatest risk;However, the incidence of ESRD has increased in all racial groups. Because hypertensive patients with ESRD require dialysis often, the cost of treatment of this disease is extremely expensive.The main effect of reducing blood pressure in patients with ESRD is not properly treated.Results from several studies show that lowering blood pressure may improve kidney function and that ACE inhibitors and calcium blockers in the United States,there is an increased incidence ofchronic renal failure and high cost due to treatment.

Implementation of IoT Based Attendance System on a Dedicated Web-Server[ ]


In this paper the concept of Internet of Things (IoT) is applied to the basic attendance system in a class room. A portable device is designed, where in every student can feed his/her attendance during each lecture. The student verification is done using R-305 Finger Print module. The student data is fed already in the finger print module. Once successful recognition of finger print pattern is done, the student’s attendance is ready to be pushed to the web-server. This data is sent through the serial interface to the Arduino. Arduino provides a data sequence, which is a combination of the student ID, teacher ID and device ID i:e a unique no. of the hardware, so that the attendance cannot be forged. This combination is then sent to the web-server using Wi-Fi Module esp8266-01. This combination is to be sent to the web-server, where it will be decoded. In order for this value to reach the web-server, esp8266 provides wireless connection to the access point, which is in the range, and whose credentials are available. Esp8266 gets access to the internet from the access point(AP), whose Service Set Identifier (SSID) and password is fed in the esp8266 module already. Once the combination reaches the web-server, a PHP script does the subsequent work, to interpret the data, and the MySQL database is updated. Data from the database is retrieved and sent to the website for easy viewing by the student. The whole system is implemented on a dedicated web-server. As a result, the real-time behavior can be analyzed, which helps us to understand the latency and efficiency of the entire system.

Effect of Tropospheric Air density and dew point temperature on Radio (Electromagnetic) waves and Air radio wave refractivity[ ]


Signal strengths measurements were obtained half hourly for some hours and simultaneously, the atmospheric components: atmospheric temperature, atmospheric pressure, relative humidity and wind direction and speed were registered to erect the effects of air density and dew point temperature on radio signals (electromagnetic waves) as they travel through the atmosphere and air radio wave refractivity. The signal strength from Cross River State Broadcasting Co-operation Television (CRBC-TV), (4057'54.7''N, 8019'43.7''E) transmitted at 35mdB and 519.25 MHz (UHF) were measured using a Cable TV analyzer in a residence along Ettaabgor, Calabar, Nigeria (4057'31.7''N, 8020'49.7''E) using the digital Community – Access (Cable) Television (CATV) analyzer with 24 channels, spectrum 46 – 870 MHz, connected to a domestic receiver antenna of height 4.23 m. Results show that: on the condition that the wind speed and direction are the same or (0 mph NA), the radio signal strength is near negligibly directly proportional to the air density, mathematically Ss / ∂a1.3029 = K, where Ss is Signal Strength in dB, ∂a is Density of air Kg/m3 and K is constant; radio signal strength is slightly inversely proportional to the dew point temperature; irrespective of the wind speed direction, mathematically, Ss x Td0.761 = K at same wind speed and direction, where Ss is Signal Strength in dB, Td is Dew point temperature in 0C and K is the constant; also, the air radio wave refractivity is slightly directly proportional to the air density, not taking into cognizance the wind speed and direction, since the radio refractivity formula is not a function of wind, mathematically, NR / ∂a0.4443 = K where NR is Air radio wave refractivity in inHg20F1/2%1/3, ∂a is Density of air Kg/m3 and K is constant; finally, the atmospheric radio wave refractivity is slightly directly proportional to the dew point; irrespective of the wind speed direction, mathematically Ss / Td0.2662 where Ss is Signal Strength in dB, Td is Dew point temperature in 0C and K is the constant.

Image Search Reranking[ ]


Image search reranking (ISR) has been implemented in order to get a refined image search as per the user needs. ISR fails to capture user expectation and needs for the search of a particular text query. In order to improve this reranking with user interactions or active ranking is highly demanded to improve the image search performance. Use of visual information can be used to solve text-based image retrieval. Among the papers referred for literature survey the techniques that can be implemented are, reverse K Nearest Neighbor (KNN), Hypersphere-based Relevance Preserving Projection (HRPP) and ranking function Hypersphere-based rank (H-rank) and K means clustering. HRPP is used to sort the images into various categories and sort. Reverse KNN is used in order to review On- Click Hypersphere based Relevance Preserving Projection (OC-HRPP) to know the exact search of the user. H-rank technique uses Euclidean distance formula and gives us all user relevant refined image result.

Structural Reliability of RCC buildings subjected to seismic loads[ ]


Reliability Analysis is a vital ingredient for a successful structural design. It assists the Engineer to consider all possible structural uncertainities by calculating the probabilities of failure during the analysis, design, construction and life span of structure. Therefore a well known methodology of reliability analysis has to be adopted to evaluate the seismic performance of reinforced concrete buildings. The lateral displacement of a building during an earthquake has an important impact on its structural performance. Estimation of seismic hazard in any region needs the complete data of previous earthquakes with a uniform magnitude scale.
