Effect of Dirt on Global Irradiation Measuring Equipment in Coastal Conditions in the Arica and Parinacota Region[ ]


The aim of this study was to evaluate the effect of environmental dirt on the global irradiation measurement equipment installed in a weather station in the city of Arica, Chile, as well as characterizing the content of the settleable particulate material deposited on the station. Since it was not possible to use two pyranometers simultaneously in the elaboration of this research, the first step was to obtain a model of global irradiation using the other data available from the weather station as input variables. Calculating global irradiation by adding the direct and diffuse components is an effective method (4.5% average error), although the use of a polynomial equation allows this error to be reduced (3.5% average error). It was observed that the error in the measurement is related to the irradiation level and the presence of three characteristic zones: (i) when irradiance is below 50 W/m2 the largest errors are present (ii) when irradiance is between 50 and 500 W/m2 the error increases as irradiance increases (iii) above 500 W/m2 the error stabilizes in the region of 5-6%. In addition, it was determined that the effect of dirt is negligible during the first 7 days. The minerals present in greatest proportions were identified as: Halite, Gypsum, Quartz, Albite, Anorthite and Anhydrite. All these minerals appear to be originate from natural sources of contamination such as the proximity to the Pacific Ocean and the desert conditions in the area. No mineral that may be associated with anthropogenic sources was found in any great quantity.

Locally Optimized SSAC: LOSSAC[ ]


A new method of locally optimized sample consensus based on S-estimator has been introduced in this paper (LOSSAC). Locally optimized RANSAC (LORANSAC) and other locally optimized procedure are developed based on M estimator. The weakness of M estimation is the lack of consideration of distribution of data and it is not a function of overall data, because it uses median as the weight value. The proposed method uses the residuals standard deviation to overcome the weaknesses of median. The performance of the improved SSAC is studied and compared with LORANSAC and LOMSAC. The LOSSAC provides reliable results and more efficiency by comparing with the number of inliers estimated under various procedures.

Broadband Network Penetration and Growth Pattern in North Eastern Part of Nigeria[ ]


Information and Communications Technology, like many other classical innovations has been institutionalized and become myths binding on organizations. How this seditious tool can be used as a catalyst for developing countries, in the face of empirical anomalies has been a cause for concern. Why does increasing number of agencies go on-line and establish similar web presences with similar structures even when delivery to end user is poor or near impossible? What are the processes of adaption to the environment and pressures of legitimacy and service efficiency? Nigeria, like many other developing nations, confronts huge problems relating to information dissemination. Different government organs have made rigorous efforts to improve the penetration rate. How these efforts affect different regions of the country was the subject of this investigation. Accordingly, multi-stage sampling technique was used to access stakeholders’ views from a critical region of Nigeria, using stratified and simple random sampling methods. Key indicators of the results showed that: broadband penetration constitutes a major problem to ICT service delivery{X2 calculated (6.250) was less than X2 tabulated (9.488)}. The impact of Broadband infrastructure as an antidote to improve ICT service delivery indicated X2 calculated (5.185) to be less than X2 tabulated (9.488). The study also arrived at a synergy between speedy broadband growth and technological advancement: X2 calculated (1.559) was less than X2 tabulated (15.507). Evidently, the North Eastern region of Nigeria lacks innovation, capacities and capabilities in broadband network outside few organizations in the capital cities and the financial institutions.

Empirical Review of Basic Concepts of Teletraffic Postulates[ ]


Before the advent of the present heterogeneous teletraffic environment, telecommunications’ researchers had postulated different models aimed at appraising the performance of networks. .Some of these concepts were applied by tele-traffic engineers inter-changeably; in spite of the different characteristics of the signals. The study examines some of these related models and their applications in the present telecommunications environment. Network efficiency was measured by varying the capacity of servers using two different Grades of Service (GoS). At GoS of 0.005, the network recorded operating efficiency of 68 per cent. While at GoS of 0.02, it recorded server efficiency of 77 per cent. Network efficiency increased as the number of routes increased. However, as more routes were configured to carry traffic, the study observed a steady growth of network saturation; where increase in number of servers did not correspondingly increase network efficiency, irrespective of the configured GoS. Individual call holding times were also found to be negatively exponentially distributed. The study confirmed that most of these postulates were clearly workable engineering procedures with theoretical leanings. Also, the approximation of discrete repetitions by a continuous queue will be unrealistic, unless the group is large and heavily-loaded. The present inadequacies of some of these models are fairly clear. Subscribers do not have infinite persistence. It is possible for further works to consider slightly more complex queuing behaviour to cope with the present heterogeneous traffic scenario.

The Security Implications of Virtual Local Area Network (VLAN),Niger Mills, Calabar, Nigeria[ ]


Virtual local area network (VLAN), is a logical grouping of network users and resources connected to administratively define the operation of activated ports on a switch. The creation of VLAN is saddled with the ability to develop smaller broadcast domain within a layer-2 switching router; by assigning different ports on the switch to different sub networks. The application was a re-design project carried out on the Niger-Mills’ network to improve the operational short falls identified by the operators. Niger-Mills’ LAN network covered a total of 5 departments:: marketing, sales, finance, engineering and management. Five (5) users were randomly sampled and selected from each department to constitute their individual LAN, making a total of 25 computers. The project successfully introduced this process in the Niger-mills LAN as a test run. It was further recommended that switch-model 2950/3560 be introduced to activate this function automatically. From the trouble shooting process, it was obvious that layer-2 switches only read frames for filtering. They don’t access the network layer protocol, and by default, switch forward all broadcast. But the creation and implementation of VLAN, essentially activated a small broadcast domain at layer-2.

Adopting the Object-Oriented Paradigm in Document Management[ ]


The introduction of the object-oriented paradigm in programming has marked an upsurge in the development of object-based applications to replace the age-long relational database paradigm. The object-oriented programming (OOP) concept gives a new dimension which has perfectly been employed in complex programs. In this paper, OOP is employed in the design of a document management system suitable for large organizations which hitherto have been using the traditional manual document management system through the file cabinets. It is obvious that a paperless office concept is gradually replacing the manual concept; however, the method of documentation is still very clumsy from organization to organization. This paper attempts to remove the bottleneck involved in such systems.

Estimation of Throw Distance in the Design of Ski-Jump Bucket[ ]


The design of ski-jump bucket for a particular dam is very complex in nature, as it involves variables such as discharge intensity, head over spillway, lip angle, bucket radious and frictional losses. Prototype jet trajectory length is found significantly shorter than the theoretical distance computed using various empirical equations. Throw distances computed using equations such as BIS, USBR, Kawakami (1973) are compared with those observed in the model studies conducted in the present studies. On the basis of path of trajectory, new equation for computing throw distance has been developed. Throw distances computed by using new equation compared with the throw distances observed in model studies. The developed equation is also applied for computing Prototype jet trajectory length.

Physical Assessment of Pozzolanic Activity of Saudi Kaolinitic Clays for Use in Sustainable Cement-based Materials[ ]


Presently, there is a growing concern in calcined clays as supplementary cementitious materials SCM, because of their relatively great geographic distribution and their demonstrated pozzolanic properties once calcined under specific conditions. In this study, two different Saudi kaolinitic clays (from KHUSHAYM RADI DEPOSIT) were calcined at three different temperatures 650, 700 and 750 °C, the influence of calcination temperature on the mineralogical compositions and micro-morphologies were investigated by X-ray diffraction spectrometer XRD and the scanning electron microscope SEM respectively. The pozzolanic activities were studied using hydrated lime as an activator. 80% clay – 20% hydrated lime pastes were prepared using water/solid ratio = 1 (on basis of mass) and hydrated for 3 and 7 days. The phase composition/decomposition of the hydrated pastes was identified by using differential scanning calaorimetry (DSC) and XRD. The microstructure characteristics and x-ray microanalysis were examined by SEM equipped with energy dispersive analytical x-ray unit (EDAX). Significant modifications in the micro-morphologies have been observed due to calcination. The investigated clay samples showed different pozzolanic activities.

Adaptive Local Image Contrast in Image Binarization[ ]


Image binarization is the process of separation of image pixel values as background and as a foreground. We set white pixels as background and black pixels as a foreground. It firstly convert the degraded document image into gray scale document image and then in to binary document image. To perform such a segmentation of document image into background and as a foreground Most of the binarization techniques consider the intensity values associated with pixels. To distinguish these intensity values we will consider one intensity value called threshold. Each and every pixel of the gray scale images compared with the threshold value and according to that pixels are separated as background pixel and foreground pixel. Thus selection of threshold value is important for the separation

Need Of REIT & It’s Prospective Implication In India[ ]


A Real Estate Investment Trust is a company which modelled after mutual fund that owns or finances income-producing real estate. It provides investors regular income streams, long-term capital appreciation and diversification. REITs typically distribute all of their taxable income as dividends to shareholders. On those dividends shareholders pay the income taxes. REITs are strong income vehicles because REITs must pay out at least 90 percent of their taxable income in the form of dividends to shareholders .Office buildings, hotels, shopping malls, apartments, resorts, warehouses, self-storage facilities and mortgages or loans are the income producing real estate assets of REITS.India has also tried to establish REIT. Mainly due to global slowdown and resultant impact on the property markets in India the earlier attempts to introduce REITs in India did not succeed. The other aspect is mortgage backed securities which is not permitted to invest, resulted real estate market opportunities shrinkage. However, SEBI announced the draft consultation paper on Real Estate Investment Trust (REIT) Regulations on October 10, 2013. Earlier in 2008, SEBI had issued certain draft regulations for introducing REITs. I-REITs (REITs in India) will invest in completed rent generating properties in India (to comprise minimum 90% of net asset value) and mortgage backed securities, would issue securities, which would be listed on stock exchanges and. In earlier phase I-REITs are planned to be available only to high net worth individuals and institutions to develop the market but now there are some relaxations introduced.

Reviewing Different ECG-Signal Feature Extraction and Classification Approaches[ ]


Electrocardiogram (ECG) is continuous recording of electrical signals of heart against time. The analysis of ECG signal is essential and proves important in detecting cardiac peculiarities. Electrocardiographic signals are nothing but numerous presence of noise added from different sources. Some commn noise source that affect or disturb basic electrocardiogram are mainly power line interference, medical operating devices noise and electromagnetic field interference from other sources, noise due to random body movements and breathing movements. Noises are classified on basis of their frequency content and time variation. It is absolutely necessary to reduce these disturbances in ECG signal to improve accuracy and reliability. Noise minimizes after removing high and low frequencies. Basic classification is performed in two class namely abnormal and normal signal. ECG signal gets classified on intervals in PR, RR and QRS width from this decision rules are form. At primary stage abnormal signal of human heart detect cardiac patients.

Fabrication of yttria dispersed duplex stainless steel electrode to determine dopamine, ascorbic and uric acid electrochemically by using cyclic voltammetry[ ]


The elemental Fe-18Cr-13Ni was mechanically alloyed in a dual drive planetary mill for 10h to prepare nanostructured duplex stainless steel powder. The prepared duplex stainless steel powder was mixed with 1wt% Y2O3 nano particles in a turbula mixer for 2h. The yttria dispersed duplex stainless steel powder was characterized by XRD, SEM and particle size analysis. Yttria dispersed duplex stainless steel powder of 2, 4, 6, 8, 10 and 12mg concentrations were modified individually with carbon paste electrode to investigate the electro catalytic response of the fabricated electrode. Yttria dispersed duplex stainless steel modified carbon paste electrode (YDMCPE) shows splendid electrochemical sensitivity towards the oxidation of dopamine (DA), ascorbic acid (AA) and uric acid (UA) than yttria free duplex and bare carbon paste electrode (BCPE). 8mg YDMCPE show maximum anodic peak current in detecting 2mM DA in 0.2M phosphate buffer solution of pH 7.2 at scan rate 100mVs-1. We studied the effect of scan rate, effect of concentration of analyte used and the effect of pH in detecting DA, AA and UA. All the above studies depicts that YDMCPE show better electro catalytic response towards anodic oxidation of DA, AA and UA because of its fast response, reliable, material maculating resistance and stable nature.

Impact of Static Var Compensator (SVC) Tuned by Harmony Search Algorithms on Wind Energy Conversion System (WECS) Stability[ ]


This paper studies the effect of static var compensator (SVC) on stability of the wind energy conversion system (WECS) based on fixed speed induction generators (FSIG). Due to the nature of asynchronous operation, system instability of wind farms based on FSIG is largely caused by the excessive reactive power absorption by FSIG after fault due to the large rotor slip gained during fault. It was found that the SVC considerably improves the system stability during and after disturbances, especially when the network is weak. Moreover, this paper shows by using Harmony Search Algorithm (HS) and Self-Adaptive Global Harmony Search Algorithm (SGHS) instead of a Conventional Control Method for tuning the parameters of PI controller for SVC, the performance of the system with SVC is improved under different fault scenarios. MATLAB/Simulink based simulation is utilized to demonstrate the application of SVC in wind farm integration. it is also carried out to investigate the enhancement in performance of the WECS achieved with a PI Controller tuned by Harmony Search Algorithm as compared to a Conventional Control Method
