Industrial Building Systems (IBS) as an Alternative Approach for Housing the Poor in Sudan

Housing for the poor is one of the foremost troubling issues for governments, since independence, the government of Sudan has pledged to undertake to unravel the housing problem for low-income people, but the growing demand populations far exceed what's on the table to unravel this problem. The research aims this is to review the potential of an industrialized building system (IBS) for low-cost housing provision in Sudan. the current conventional construction system (CBS) that used for this sort of building is linked to several problems: inefficiency, slow delivery rate, poor quality standards but at an equivalent time helps create many roles like doesn’t depend on skilled labor and elegance flexibility. due to its capacity to line up group projects faster than CBS can, the industrialized building system is usually used to meet the urgent need for housing for the displaced because of its ability to equip collective projects quickly and in high quality, the best example of which was used extensively after the Second war in many European countries affected during the war. Although IBS could even be a replacement system in Sudan, it's expected to spread rapidly, with appropriate material value and high quality to satisfy the requirements of the end-user. For more efficient, a system is usually developed that mixes the characteristics of the conventional and industrial systems to unravel the housing problem for the poor in Sudan. The research results are helped the government to spot the possibility of industrial buildings as an appropriate solution to the housing problem in Sudan. Also help the government on the power of industrial buildings as an efficient solution for the housing problem in Sudan, particularly low-income housing. The aims of the research to support government initiatives to affect the poor in Sudan. It is largely debatable due to its importance, and importance to government-supported housing objectives and thus the particular impacts of the initiative and its performance for low-income housing in Sudan

Applications of the operator rɸs in q-polynomials

We establish rΦs as a general operator for many q-operators. A new polynomials hn(a1, · · · , ar; b1, · · · , bs; x, y; q) are described as an extension of the bivariate Rogers-Szegö polynomial hn(x, y|q) and the generalized Al-Salam–Carlitz q-polynomials φ n (a,b) (x, y|q). With the use of the operator rΦs, we provide an operator proof of the generating function and its extension, Mehler’s formula and its extension and Rogers formula and its extension to the polynomials hn(a1, · · · , ar; b1, · · · , bs; x, y; q). The generating function and its extension, Mehler’s formula and its extension and Rogers formula and its extension for hn(x, y|q) and φ n (a,b) (x, y|q) are deduced by giving special values to parameters of a new polynomial hn(a1, · · · , ar; b1, · · · , bs; x, y|q).Publisher's Versio

Estimation of Rice Evapotranspiration in Paddy Fields Using Remote Sensing and Field Measurements

Water resources are limited in many parts of the world. Due to the fast growing world population, the demand for domestic and industrial water use is increasing tremendously. This results in reduction of water for agricultural use, especially for major rice growing areas which needs huge amounts of water. The study was carried out in the northwest of Selangor, in the Tanjung Karang Rice Irrigation Project Malaysia. The objectives of this study were to estimate the rice evapotranspiration using satellite data and compare it with the field measurements. Eight sets of non-weighing lysimeters (91 cm x 91 cm x 61 cm) with attached casella hook were installed to measure the crop evapotranspiration at five different locations within the 19000 ha rice irrigation scheme. Global positioning system (GPS) was used to locate the lysimeter position. The rice yields in the lysimeters were manually measured for three seasons. An automatic meteorological station was installed inside the field to collect data required for calculations of the crop evapotranspiration using the CROPWAT software. NOAA satellite data was used as data input to correlate the remote sensing data with field evapotranspiration data. For three seasons, the off (dry)season from December to May, the main (wet) season from July to November, the observed ET from the lysimeters ranged from 3.2 to 5.8 mmlday, while ET by calculation using weather parameters ranged from 3.15 to 5.72 mmlday. There was no significant difference between the blocks in the first season of the experiment because of the small area and not much difference in the environmental conditions within the block. Most of the correlation for the second and the third season were significant at 0.01%. The corresponding ET values from satellite data were 4.04 to 6.54 mmlday. Considering ET measured by lysimeter as the most accurate method, ET determined using satellite data overestimates and by computed method underestimates those obtained by lysimeter. ETc by NOAA data were found to overestimate by 8% to 12% with an average of 10%. Using CROPWAT, ETc were found to be underestimated between 7% and 20% with an average The significance findings of this research are that ET can be estimated for paddy areas in Malaysia with reasonable accuracy using satellite data or computed method. The implications are that much time and cost can be saved using these alternative techniques compared to manual data collection from lysimeters. This will result more efficient water management planning in the rice areas. Generally, by knowing the actual ET, the cropping calendar can be prepared at the beginning of the cultivation season by knowing the amounts of water needed throughout the season

Series Solutions of Multi-Layer Boundary Value Problems

It is well known that differential equations (DEs) play an important role in many sciences. They are mathematical representations of many physical systems. By studying such DEs, one gains many important insights about the physical system. Solutions of DEs provide information on the physical system behavior. As many physical systems are nonlinear in nature, this naturally gives rise to nonlinear differential equations (NLDEs). Such NLDEs are, in most cases, hard or sometimes impossible to solve analytically. In such situations, we resort to numerical techniques to approximate the solutions. The purpose of this thesis is to consider nonlinear multi-layer boundary value problems and seek approximate solutions. Many methods exist in the literature to numerically solve nonlinear boundary value problems. However, only few papers dealt with nonlinear multi- layer boundary value problems. In this work, we employ the homotopic analysis method (HAM) as the method of choice. We consider a real physical system dealing with the fluid flow in multi-channel porous media whose governing equations is exactly a nonlinear multi-layer boundary value problem

Case Study of Thermal Injection in Heavy Oil Reservoir

A study has been done on thermal injection – as an enhanced oil recovery - in heavy oil reservoir. Two types of thermal injection were discussed. These methods are cyclic steam stimulation and steam flooding. The simulation part was done using Eclipse 300 and literature data. Moreover, steam flooding technique was used in simulating the reservoir. It was confirmed that thermal injection is significant in heavy oil reservoir. It was shown that the viscosity is the main variable that affects the production rate and the recovery factor of the field. By decreasing the value of this variable the production rate was significantly increased. Using thermal injection increased the recovery factor from 3.75% to 56.5%
