Implementation of Low Cost Radon Measuring System for Air Quality Monitoring

Because inhaling radon and its radioactive decay products causes irradiation of lung tissue, the radon data obtained from houses and workplaces need to be transferred using Wi Fi and the Internet to a database on a radon monitoring server system. To do this, a PIN photodiode radon measuring system was implemented and the ESP8266 Wi Fi module was used for wireless communication. Through some experimental studies, we showed that the data transmission using these Wi Fi modules was very successful.

Structure, Biomass Carbon Stock and Sequestration Rate of Mangroves in the Bakassi Peninsula, S W Cameroon

The forest plays a major role in stabilizing increasing temperatures due to its climate mitigation capacity. This is not unconnected to the carbon storing and sequestration potentials of forests. The mangrove as one of the global forest types is said to be a major carbon store. This conclusion is characterized by some knowledge gaps on the actual carbon stock and sequestration potentials of some mangroves forest on the Central African Sub regional landscape. Some of these areas are the Bakassi mangroves in the South West Cameroon. Cross border conflicts, piracy and over exploitation have rendered the sourcing of appropriate data on its carbon stock and sequestration potentials difficult. In strive to bridge this knowledge gap, this work carried out a baseline assessment of the carbon stock and sequestration rate of the area. To achieve the study objectives, stratified random opportunistic sampling inventory design based on five forest canopy height classes, tree Diameter at Breast Height DBH and canopy nature using digital elevation model DEM of the shuttle Radar Topographic Mission SRTM . This combination evaluated the species type and forest structure around the areas. Carbon stocks were estimated with the use of allometric equations using biomass data collected within main plots, sub plots, micro plots and transects. Results showed that mean biomass carbon stock density for the height classes for Bakassi ranged from 33.5 Mg ha to 598.9Mg ha. Thus on average, for a hectare in Bakassi, the carbon stock is 880.437 Mg ha and a sequestration rate of 3231.204 tCO2e ha .

Bubble Wrap The Key to a New Floating Solar Thermal System

Solar Thermal Energy STE is a form of energy and a technology for harnessing solar energy to generate thermal energy or electrical energy for industries and to desalinate water and to treat waste water, among other things. Here we demonstrate a floating solar receiver which is capable of generating 1000C steam under ambient air conditions without optical concentration. Here the high temperatures are achieved by using thermal concentration and heat localization. This reduces the convective, conductive and radiative heat losses. This demonstration of a low cost and scalable solar vapour generator holds the promise of significantly for expanding the application domain and reducing the cost of solar thermal systems.

Simulation Analysis in Lateral Torsional Buckling of Channel Section by Using Ansys Software

Design rules for eccentrically loaded beams with open channel cross sections are not available in Indian code IS 800 2000 general construction in steel code of practice third revision . In this study Indian standard medium weight parallel flange ISMCP 175, ISMCP 200, ISMCP 3000 channel beams are used different span length to section height ratio of the beams is taken. The type of loading and the uniformly distributed load application are limited through the web of the channels. General solutions like Elastic critical moment, Slenderness, Reduction factors and the Ultimate loads are determined by using formula given in ANNEX E CL.8.2.2.1,IS 800 2007 for mono symmetric beams and compared with NEW DESIGN RULE snijder and with Finite Element FE simulations on the basis of a parameteric study using ANSYS software 14.0. It is was noticed that mono symmetric formula in code is giving elastic critical moment results upto 0.3 difference with ANSYS result for slender beams but showing larger difference for stocky beams. As the size of beam is increasing with constant cross section it is resulting in reduction in design capacity. The design curve for channel beam proposed by snijder seems to be a good choice , taking torsional effect into account, but it dosent claim to be correct for beams with a ratio L h 15. The results obtained from the IS code formula is matching with ANSYS results for beams having length to depth ratio between range 20 to 40.

Obtaining Modal Parameters in Steel Model Bridge by System Identification using Artificial Neural Networks

Artificial Neural Networks are easy to build and take good care of large amounts of noisy data. They are especially suitable for the solution of nonlinear problems. They work well for problems where domain experts arent available or there are no known rules. Artificial Neural Networks can also be adapted to civil engineering structures and suffer from dynamic effects. Structures around the world were badly damaged by the earthquake. Thus, loss of life and property was experienced. This particularly affected countries on active fault lines. Pre and post earthquake precautions have been developed in the world. For these reasons, it is ne

cessary to determine the dynamic performance of structures in the world. There are several methods to determine dynamic performance. System identification is one of these methods. The mathematical model of the structural system is obtained by system identification method. Artificial Neural Networks ANN is a system identification method. ANN can adapt to their environment, work with incomplete information, make decisions under uncertainties and tolerate errors. Steel Model Bridge was used in this study. The system identification of the steel model bridge with the ANN method of 0.90 was made successfully. As a result of this study, ANN approach can provide a very useful and accurate tool to solve the problem in modal identification studies.

Investigation of the Dielectric Performance of Mineral Oil -Based Nanofluids

The ongoing demands for the extra high voltage boost the need for looking for improving the conventional insulating materials by various modification techniques. Transformer insulating oil based nanofluids NFs is one of these techniques. The present work aims to investigate the dielectric performance of transformer oil based nanofluids and their dependence on the type of nanoparticles. To achieve this, three types of nanoparticles namely Zinc Ox ide ZnO as conductive nanoparticle, Titanium Oxide TiO2 as semi conductive nanoparticle and Silicon Dioxide SiO2 as dielectric nanoparticles have been suspended in mineral oil MO at various concentration levels and the dielectric performance was tested by performing experiments such as AC breakdown voltage test, relative permittivity and DC conductivity. Experimental findings reveal that the use of nanofluids technique could improve the efficiency of the dielectric performance of mineral oil. The nanoparticle type and concentration have critical effect on the dielectric performance of prepared samples. For breakdown voltage, it is manifested that, samples prepared with ZnO nanoparticles exhibited the highest percentage of improvement. While for relative permittivity, samples prepared with TiO2 nanoparticles at higher concentrations, showed the highest percentage of improvement. On the other hand, all samples showed higher values in conductivity comparing with bare mineral oil sample.

Modeling Analysis and Design of Intz Water Tank Considering Different Wind Speed using STAAD PRO V8I Software

In order to compete in the ever growing competent market it is very important for a structural Engineer to save time as well as money, as a sequel to this is an attempt made to analyze and design a INTZE water tank by using IS method and software package of staad.pro. For analyzing a INTZE water tank one has to consider all the possible loadings and see that the structure is safe against all possible loading conditions. STAAD Pro V8i is a comprehensive and integrated finite element Analysis and design offering, including a state of the art user interface, visualization tools, and international design codes. There are several methods for analysis of different frames like finite element method. The present project deals with the design and analysis of a INTZE water tank with 12 lakh liters capacity for Jharkhand. The dead load, live loads and seismic load are applied and the design for different structural component, columns is done by using IS code method and STAAD.Pro with its new features surpassed its predecessors, and competitors with its data sharing capabilities with other major software like AutoCAD, and MS Excel. Intzetank is a type of elevated water tank supported on stagingThere are several methods for analysis of different frames like finite element method.Analysis of results of structural design and estimation of quantities of Intze tank for different wind speed and different bearing capacity of soil, For same bearing capacity of soil, if wind speed is increased the quantity of concrete and steel in Intze type elevated water tank are also increased. For same bearing capacity of soil, if wind speed is increased the quantity of concrete and steel in Intze type elevated water tank are also increased. Keeping the values of bearing capacity of soil constant, for every incremental increase of 10 m sec of wind speed, the quantites of concrete is increased.If the design of intze type elevated water tank is devided into two parts namely super structure above columns and super structure upto columns the analysis of results of this study reveals that with the change in the wind speed and or the bearing capacity of soil, there is an appreciable change is required quantities of concrete and steel for sub structure while these is almost no change in the required quantities of concrete and steel for super structure.
