The transfer of the provincial capital from Ternate to Sofifi caused almost allgovernment activities to be transferred to Sofifi. This is indicated by the increasingnumber of commuters who travel between islands with surrounding islands or districts(hinterland) or between regions within the city. Sea transportation as a means ofconnecting between islands is still very minimal, lack of infrastructure, limited numberof transportation to high transportation costs. The purpose of this study was to determinethe characteristics of PNS commuters in the island cluster area and analyze the chain ofcommuter PNS trips in the island cluster region in North Maluku province. Theinterview survey was conducted to determine various personal characteristics andpatterns of commuter travel chains. The results of this study are expected to provide anoverview of the characteristics of the computer travel chain in the island cluster regionin North Maluku Province.

The use of Masonry panels in building construction has been popular in most of the parts of the world. However, the use of bricks and brick masonry in different parts of the world being of different nature in terms of quality, size, workmanship of construction, etc. It is yet a topic of interest to researchers to identify the mechanical properties, like Young’s modulus of elasticity and shear modulus of brick masonry panels. It is essential to know the characteristic of brick masonry panels in order to evaluate the responses of masonry walls for any kind of loading. Individual bricks do possess better compressive capacity as compared to masonry walls. Masonry walls are bound together with either mud mortar or by cement sand mortars of various mixes as per the strength requirements. The essential strength properties in engineering are basically the compressive strength and the modulus of elasticity. The American Society for Testing and Materials (ASTM) standard is the most popular for testing bricks and brick masonry for these properties so far. Here, the study has been concentrated in finding the compressive strength of brick, mortar and brick masonry. The study is also done for Young’s modulus of elasticity of brick as well as that of masonry wall. Similarly, the study is extended to find the modulus of rigidity of brick masonry panel. The study is done experimentally for the samples that are generally used in Kathmandu, Nepal. The samples include bricks, cement and sand particularly available in Kathmandu region.

Water is necessary for all life on earth. Every living creature on the Earth depends on water for their survival; however the supply of water on Earth is limited. Groundwater, the important source of water supply to many people around the world, is accessed through stone spouts, springs, dug wells and infiltration galleries in and around Kathmandu Valley since ancient time. The extraction of groundwater in Kathmandu Valley is increasing day by day due to increase in population, haphazard urbanization and unplanned industrialization. Drinking water quality and quantity is one of the major issues which need to be taken seriously, since clean water and sanitation are human rights and essential to life. The present study aims to prepare water table map and groundwater quality map from unconfined aquifer of Bhaktapur Municipality. Geographic Information System (GIS) based groundwater table mapping for 472 samples were used. Inverse Distance Weighted (IDW) method was used for 86 samples for spatial interpolation of chemical indices. Surface maps are prepared for water quality parameters (pH, turbidity, conductivity, TDS, total hardness, iron, ammonia, nitrate, chloride, alkalinity and E-coli) in the GIS Software by interpolation between the available data. Water table elevation map shows that groundwater levels are shallow at wells located close to agricultural field. From the water quality mapping of the Bhaktapur Municipality, it is seen that the most of the water quality parameters are within the maximum permissible limit set by WHO and NDWQS. It is noted that quality of ground water in the study area exceeds Nepal drinking water quality standards on the basis of measured values of chloride, ammonia and nitrate in majority of wells. High concentration of chloride, ammonia and nitrate were found in most of water samples from the central part and in around the periphery of the municipality boundary, which may be due to infiltration of agricultural runoff and leaching of sewage pollutants.

The research work reports the results concerning the effects of ozone produced by dielectric barrier discharge (DBD) in well, river and industrial wastewater. The dielectric barrier discharge (DBD) unit was developed to produce highly oxidizing ozone molecules, hydrogen peroxide and hydroxyl radicals for the treatment of water. The discharge was produced by applying AC high voltage (up to 10 kV peak-to-peaks) source of frequency 26 kHz across annular electrodes. The well and wastewater samples were collected from 5 different places of Kathmandu district, Nepal. Various physical, chemical and micro-biological parameters such as pH, Electrical Conductivity (EC), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Coliform were analysed before and after ozonation. Our results showed that pH of water after treatment changed slightly with respect to pH of untreated water. There was slight change in conductivity of water from the different sources after treatment by ozone. DO of all samples increased significantly after ozonation. It was found that BOD and COD of all samples decreased significantly after ozonation. Concentration of ferrous ion (Fe2+) decreased after ozonation. There was significant decrease in Total Coliform after treatment.

Digital images have been a major form of transmission of visual information, but due to the presence of noise, the image gets corrupted. Thus, processing of the received image needs to be done before being used in an application. Denoising of image involves data manipulation to remove noise in order to produce a good quality image retaining different details. Quantitative measures have been used to show the improvement in the quality of the restored image by the use of various thresholding techniques by the use of parameters mainly, MSE (Mean Square Error), PSNR (Peak-Signal-to-Noise-Ratio) and SSIM (Structural Similarity index). Here, non-linear wavelet transform denoising techniques of natural images are studied, analyzed and compared using thresholding techniques such as soft, hard, semi-soft, LevelShrink, SUREShrink, VisuShrink and BayesShrink. On most of the tests, PSNR and SSIM values for LevelShrink Hard thresholding method is higher as compared to other thresholding methods. For instance, from tests PSNR and SSIM values of lena image for VISUShrink Hard, VISUShrink Soft, VISUShrink Semi Soft, LevelShrink Hard, LevelShrink Soft, LevelShrink Semi Soft, SUREShrink, BayesShrink thresholding methods at the variance of 10 are 23.82, 16.51, 23.25, 24.48, 23.25, 20.67, 23.42, 23.14 and 0.28, 0.28, 0.28, 0.29, 0.22, 0.25, 0.16 respectively which shows that the PSNR and SSIM values for LevelShrink Hard thresholding method is higher as compared to other thresholding methods, and so on. Thus, it can be stated that the performance of LevelShrink Hard thresholding method is better on most of tests.

The study was conducted to evaluate the impact of brick kilns' on different physiochemical parameters of soils of agricultural field, located in the vicinity of Bhaktapur. The study was carried out by measuring the pH value and the micro nutrients of the soil. During the entire study period, the pH of soil near brick kiln was measured to be 5.5 and as distance increased the pH of soil was recorded up to 6.9 which mean the soil was acidic near the kiln and was neutral farther away. The findings revealed that the pH value was high and nutrient content were deficient in soil at 50 m while increasing gradually at distances of 100 m and 150 m it was found opposite of it. It signifies that the quality of soil increases proportionally to the distance from the brick kiln area. Similarly, the micro nutrients like organic matter are also increased with increasing distance.

One of the most important areas in image processing is medical image processing where the quality of the images has become an important issue. Most of the medical images are corrupted with the visual noise, and one of the such images is echocardiography image where this effect is more. So, this research aims to denoise the echocardiography image with fractal wavelet transform and to compare its performance with other wavelet based algorithm like hard thresholding, soft thresholding and wiener filter. Initially, the image is corrupted by the Gaussian noise with varying noise variances and is denoised using above mentioned different wavelet based denoising techniques. On comparison of the obtained results, it is observed that the fractal wavelet transform is well suited for highly degraded echocardiography images in terms of Mean Square Error (MSE) and Peak Signal To Noise Ratio (PSNR) than other wavelet based denoising methods. Further, the work could be enhanced to denoise the echocardiography image corrupted by other different types of noise. This research is limited to denoise the echocardiography image corrupted with Gaussian noise only.

A fresh and present look at the performance and delivery of heritage projects is required because few studies have been conducted to explore the specific project management and participant issues that contributed failed elements (time and cost) in heritage projects. The major contribution of this research is in the guidance for improvement to help avoid delays and cost overruns in future heritage renovation projects. Bhaktapur municipality is rich in heritage; here the tourism market is one of the source of economy. Bhaktapur municipality has been selected for this study because many of the heritage renovation projects have been completed each year. Most of heritage renovations have been done with the help of users committee and amanat. Tourism has become an important economic factor for the region. So the heritage renovation is studied with the impact of the delay in the works. The research design for this study is more qualitative than quantitative. The main causes of delay have been found as difficulties in financing projects and poor managerial skills. Similarly, the causes of the cost overruns have been found as material cost increased due to inflation.

With the commencement of Electronic Transaction Act, Nepal has taken further step in the field of information and communication technology. With government offices nowadays starting to use computers; there lies ahead many challenges to maximize the utilization of computing resources offered by each computer and minimize the overall cost. With many computers, so many idle resources are being wasted unnecessarily. Jobs can be distributed out to idle servers or even to idle desktops. Many of these resources remain idle during office hours off or even during office hours with many users utilizing the computing as well as memory resources. The proposed model not only utilizes resources to optimum but also makes the architecture more modular, adaptive and then provides dynamic fail over recovery and linear scalability. This approach is useful in a place which requires clusters to set up to perform resource intensive works like data processing or computing works. This model can be realized using JINI/Java Space technology which is open source technology and hence, can be cost effective as compared to other proprietary solutions. The motivating factor of this paper is to understand and identify the architectural constraint in the existing distributed application.

The position of Ki Hadjar Dewantara road is strategic location, where as an education center, office and residential center are often happened to increase in vehicle volume, especially during peak hour, consequently, this condition makes congestion on this road. There are ideas for road widening, moved side barriers and one.way traffic management, which are purposing to know traffic performance currently and generating a recommendation of traffic systems. By observations on traffic surveys were carried out on the road at 06.00 to 18.00 WIT. Traffic performance analysis is based on the 1997 Indonesia Road Capacity Manual (MKJI). The results of the Ki Hajar Dewantara road analysis showed a high level of side resistance with a value of degree of saturation (DS) in segment 1, which was 0.78, free flow speed of 31.2 km / hour, road capacity of 1953 pcu / hour. Furthermore, as an alternative solution the application of a one way system on the road section that showed a better performance with DS = 0.32 for west to east and DS = 0.22 east to west with a service level B category with stable current, speed slightly limited by traffic, the driver has enough freedom to choose a speed. The design for implementing this one-way system is good for solving problems.

The results of the Ki Hajar Dewantara road analysis showed a high level of side resistance with a value of degree of saturation (DS) in segment 1, which was 0.78, free flow speed of 31.2 km / hour, road capacity of 1953 pcu / hour. Furthermore, as an alternative solution the application of a one way system on the road section that showed a better performance with DS = 0.32 for west to east and DS = 0.22 east to west with a service level B category with stable current, speed slightly limited by traffic, the driver has enough freedom to choose a speed. The design for implementing this one-way system is good for solving problems.","PeriodicalId":36368,"journal":{"name":"AIUB Journal of Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85807530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
