In the conventional static analysis of building frames, the base is idealised on rigid supports and the building is subdivided into three parts namely, the superstructure, the foundation and the ground soil, before design. In real life situations, the soil underneath the building undergoes deformations which may alter the performance of the structure. In this paper, it is studied the effect of soil type and foundation type on the response of a building frame system with both fixed base and flexible base. The Winkler model of soil-structure interaction is adopted to study the influence of soil flexibility and foundation rigidity on a 4 storey RC building with a regular plan resting on three types of soils namely, the light peat marshy ground, wet clay and medium gravel with fine sand. Three types of foundations are considered in the study: isolated footings, tied foundation and the raft (with and without overhangs) foundations. Winkler model is developed using springs by Finite Element Method in SAP2000. The settlement, the bending moment, the shear force and the axial force are the parameters placed forth for the comparative study. Results obtained reveal an increase in the response of the structure with respect to the soil flexibility and foundation rigidity.

Drilling fluid plays the same role in oil and gas well drilling as the blood in human body. A new type of oil-in-water (o/w) emulsion drilling fluid has been developed using diesel oil as dispersed phase, brine water as continuous phase, xanthan gum as viscosity modifier and clay as emulsion stabilizer and filtration controlling agent. Initially, standard recommended techniques were opted to detect the rheological properties of the emulsions. The fluids have also shown stable properties upto 70°C after aging for 24 h. As drilling fluids encounter a lot of variation in temperature and pressure as drilling depth increases, hence the stability of such fluids becomes an imperative parameter. Furthermore, emulsion itself is a heterogeneous fragile system so the stability was investigated using shear stress-shear rate rheology measurements. Emulsions have shown strong shear-thinning (pseudoplastic) behaviour which is considered an advantageous property for the drilling fluids. Experiments conducted to determine the dynamic rheology of the emulsions have shown the elastic behaviour towards emulsion breakdown processes. The fluids have also shown physical stability after 30 days at ambient conditions. Inter-facial variables such as zaeta potential, inter-racial tension (IFT) and contact angle measurements were conducted to examine their role in stability characterization.

The aim of this software is to monitor the system about its configurations and install the required softwares to the respective system. There are four tools in this application, Fintal, Piston, Naavi and Mapel. To install these, a technique of single file installation using batch scripting is used. Batch scripting is used to execute the installation files of softwares and the softwares are installed. These installation files of softwares will be embedded as execution commands in a single file called “windows batch file”, which should be saved with the extension as “.bat”. The installation that starts will be displayed in the command prompt to know whether the softwares are getting installed correctly. After each installation, the configuration and initialization of installed softwares will be displayed. The required softwares are to be installed. Each of these performs particular tasks that are required for the management of Hospitals. Fintal is used for overall management of Hospital. This is the most user-friendly part of OAM Tool. This handles overall administrative part of Hospitals. Piston is used for storing patient’s details. This stores the patients’ reports in detailed manner of each test the patient has undergone. Naavi is used for storing Laboratory details. The tests of each patient are stored here. And the last one, i.e., Mapel which is used for storing pharmaceuticals details (Medicines). It stores the details of medicines such as from which pharmaceuticals the medicines are purchased. The license of the hospital is also stored in this part of OAM Tool. All these together form an OAM Tool. This tool also manages other required softwares like, MySQL, ODBC drivers, etc. The management of Hospitals is very important as there is a need to maintain the patient details. This technique of installation is proposed in this paper to make the installation from hardware to remote installation such as, giving the access to the system in which the tool needs to be installed and to save the time of installation process.

An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth’s surface. Earthquakes are among the most powerful events on earth, and their results can be terrifying. In0general for0design of tall0buildings both0wind as well0as earthquake0loads need0to be0considered. Governing0criteria for0carrying out0dynamic analyses0for earthquake0loads are different0from wind0loads. However many tall buildings are not so resistant in lateral loads due to earthquake. Reinforced concrete multi-storied buildings in India were for the first time subjected to a strong ground motion shaking in Bhuj earthquake. It has been concluded that the principal reasons of failure may be attributed to soft stories, floating columns, mass irregularities, poor quality of construction materials faulty construction methods, unstable earthquake response, soil and infrastructure, which were determined to cause damage to the attached structure. High-rise buildings are in high demand due to global urbanization and population growth, and high-rise buildings are likely to suffer the most damage from earthquakes. Since earthquake forces are irregular and unnatural in nature, engineering tools need to be sharpened to analyze the structure in the work of these forces. In this study, to understand the behaviour of structure located in seismic zones III for G+15 Multi-Purpose storey building model is considered for study. Performance of frame is studied through Response Spectrum analysis and comparison is made on shear force, storey drift, storey displacement and storey stiffness.

Air pollution due to burning fossil fuels is still an environmental problem today. This paper presents the research results; method of reducing HC and CO in the exhaust gas of minibus vehicles. This method uses a pollutant gas trap (PGT) device, which functions as an adsorption medium, and natural zeolite as an absorbent material. The PGT device is designed in such a way that the zeolite can adsorb HC and CO gases flowing in it. The PGT device consists of a hollow body and supporting equipment arranged in it. The cavity of the PGT device is filled with zeolite granules and can be passed through vehicle exhaust gases. The PGT device consists of laminar and turbulent flow types, while the zeolite grains used are 2.54 mm and 1.27 mm. The PGT-zeolite device is installed at the exhaust end of the vehicle, so that polluting gases are absorbed by the zeolite. The adsorption capability of the PGT-zeolite device was measured with an Automotive-Emission-Analyzer, type NHA-406EN. Turbulence type PGT device, capable of reducing pollutant gases HC ≈ 40% and CO ≈ 42% respectively for the zeolite grain size of 2.54 mm. Meanwhile, the laminar flow type PGT device was able to reduce HC ≈ 36% and CO ≈ 42% gas, respectively for the zeolite grain size of 2.54 mm. The results of this study indicate that the PGT-zeolite device has a very good ability to reduce pollutant gases in the exhaust gas of minibus vehicles. Therefore, it is necessary to continue research on the feasibility of using natural zeolite, as an absorber of polluting gases in other types of vehicles.

An amphibious vehicle is the vehicle that allows occupants to travel on both land and water. Since an amphibious vehicle must inherently possess both land and water capabilities, design of the vehicle should not compromise the requirements for a good boat as well as a good land vehicle. Although, amphibious vehicles were used for different purposes, still there is no mention of application of amphibious vehicle in recreational purposes such as beach riding, surfing on water and travel within Science Parks. Further, with depletion of fossil fuel and for all the negative effect on marine life. Hence, an attempt is made to design an electric amphibious vehicle for recreational purpose and utilize for travel within Science & Technology Park. A conceptual design was worked out and it is matched with visual aspects of amphibian animal like duck. A CAD model was prepared with structural details. Structural strength was analyzed using ANSYS software. CFD analysis was conducted for calculating drag and surface shear stress and buoyancy was calculated. Thus it gives a practical approach to construction of an amphibious vehicle for recreational purpose. The results of the CAD analysis shows that the stress on the Frame was within acceptable limit and the buoyancy conditions are fulfilled. It also suggest for a maximum speed of 40kmph on water. As look and feel of the vehicle inspired from duck beak, it gives expression of amphibian characteristics along with sporty look. Thus, the conceptual vehicle is suitable for use on land and on water inside Science & Technology park.

Published: August 2021

Statistics indicate that about 1.7 billion people can’t access a savings account and slightly above 200 million small and medium-sized enterprises are deprived access to satisfactory financial solution. Kenya views microfinances as a development instrument for poverty lessening and economic growth through ensuring financial inclusion. It is due to the acceptance of this vital role of Microfinance that Kenya has undertaken strategic microfinance reforms and regulations aimed at promoting financial inclusion through microfinance business.  The research’s general objective is to examine the effect of microfinance reforms on financial inclusion. Specifically, to determine the influence of microfinance transformation from non-deposit taking into a deposit-taking microfinance institutions on financial inclusion, to examine the association between microfinance board characteristics and public trust, to investigate the effect of microfinance licensing requirements on financial inclusion and to examine the effect of microfinance prudential standards requirements on financial inclusion in Kenya. The research adopted Financial Intermediation Theory and Public Interest Theory of Regulation.  This research utilized descriptive research design and the population targeted included all the thirteen Microfinance institutions, which were licensed by the central bank of Kenya as at 2018. The study used purposive sampling to select six microfinance banks. Both descriptive and inferential statistics were done by use of multiple linear regression analysis. The research results indicated that microfinance transformation (pvalue=0.001), board characteristics (pvalue=0.042), licensing requirements (pvalue=0.035) and prudential standards (pvalue=0.002) significantly influenced financial inclusion. Results from regression analysis indicated a strong relationship between microfinance transformation, board characteristics, licensing requirements and prudential standards and financial inclusion. The study concluded that financial inclusion in micro financial institutions increases when there is sound microfinance transformation, board characteristics, legal requirements, and prudential standards. From the findings, the study recommended that micro financial institutions should support institutions reform functions and processes.  Further the study recommended that micro financial institutions should recruit adequate and proficient workers and offer satisfactory training as well as certification for professional appreciation on strategies for microfinance reform processes and their influence on the financial inclusion of the micro financial institution. The research recommends that board members should be reliable and open so as to substantially contribute to financial performance.

Hybrid Approach for Image Defogging Process based on Atmospheric Light Estimation Process
Authors: Sungheetha Akey
Published: August 2021

Due to unfavorable weather circumstances, images captured from multiple sensors have limited the contrast and visibility. Many applications, such as web camera surveillance in public locations are used to identify object categorization and capture a vehicle's licence plate in order to detect reckless driving. The traditional methods can improve the image quality by incorporating luminance, minimizing distortion, and removing unwanted visual effects from the given images. Dehazing is a vital step in the image defogging process of many real-time applications. This research article focuses on the prediction of transmission maps in the process of image defogging through the combination of dark channel prior (DCP), transmission map with refinement, and atmospheric light estimation process. This framework has succeeded in the prior segmentation process for obtaining a better visualization. This prediction of transmission maps can be improved through the statistical process of obtaining higher accuracy for the proposed model. This improvement can be achieved by incorporating the proposed framework with an atmospheric light estimation algorithm. Finally, the experimental results show that the proposed deep learning model is achieving a superior performance when compared to other traditional algorithms.

In the rural and communal settings, land rights are culturally attached to indigenous peoples in Nigeria, especially the inhabitants of the southern part of the country. Culturally, the customary land tenure system has generic value and security in such ways that it could be transferred from one owner to owner without restrictions. Security of land tenure is a vital ingredient that enhances the transferability of greater altitudes of investment. The study adopted a random sampling method and selected 1,061 house-owners and administered a set of structured questionnaires that contained questions that probed into issues on their accessibility to land and legal security of tenure. Another set of questionnaires was differently designed to elicit information from other stakeholders (Land managers, Town planning Agencies, Community/Family Heads, etc). Data obtained from the primary source were subjected to empirical analysis. The data were also complemented by secondary data. The findings revealed the socio-economic characteristics of the house-owners, means and duration of the period of land acquisition, determinants of access to land, and the implications on the securing planning permission, construction of illegal structures and the quality of construction. Finally, the paper recommended that tenure security in customary areas can be enhanced through the formalization of customary tenure. Governments should facilitate this process, initially where there is a demand for formalization. There is a need to harmonize reform efforts across customary and statutory law, regulations.
