ABSTRACT The study Online Hotel Reservation System is the design of an electronically driven system that will enable travelers to book hotel from anywhere in the world at their convenience. This is prompted by the fact that the cost of booking a hotel accommodation is becoming increasingly high with low information of where one can get a good hotel. The main objective in this study is to design a website that is user friendly, has a secured payment system and can provide information to...
ABSTRACT The oil of the raw seeds of Livistona chinensis (Chinese fan palm) was extracted and its physico-chemical properties evaluated. The proximate composition and the anti-nutrients present in the pulp, raw seed, blanched (4, 6, and 8 minutes), cooked (20, 40 and 60 minutes) and the roasted (1100C for 5, 10 and 15 minutes) seeds were determined. An acute toxicity study was also carried out on the seed during which albino rats were differently fed the raw and also the cooked and roasted ...
ABSTRACT: In this study, the synthesis of crystalline dodecylguanidine free base and its spectroscopic characterization in nonpolar environments are described. IR as well as 1 H and 15N NMR spectra of the free base dissolved in aprotic solvents are substantially different from the previously reported spectra of arginine, or other monoalkylguanidinium compounds, at high hydroxide concentrations. The current results provide improved modelling for the spectroscopic signals that would be expecte...
ABSTRACT In computing studies, students learn a number of computing aspects, one of them being computer programming. Computer programming can be taught in different approaches and in different languages. Each approach or language has its own strengths and weaknesses. The discussion on this research was based on determining the language that has more features for providing a gentle learning curve to a first time learner. This research was conducted through an experimental approach whereby par...
ABSTRACT This study tests the patient appointments waiting time by using computer simulation which was carried out at the Iringa Referral Hospital (IRH). The study is triggered by the fact that in most Tanzania public hospitals like IRH, patients queue for a long time to get services. Basically, such situation leads to poor quality of service that leaves many patients unsatisfied. The study analyzed four experiments and critically evaluated appointments queuing model. Three models used to fo...
ABSTRACT This dissertation provides general review of Partial Differential Equations. The Finite Difference Method which uses Taylor’s Theorem for solving Partial Differential Equations and Solution of elliptic partial differential equations, it also introduces the concepts of convergence, consistency and stability of finite difference scheme, Finite Difference Method (FDM) involving direct method and Iterative method like Gauss Seidel or Gauss Seidel with Successive Over Relaxation are ap...
ABSTRACT The study of existence results on two point boundary value problems by fixed point methods, monotone iterative techniques, matching solution techniques and integral boundary conditions has been put in place in order to provide a broad understanding to the existence of two point boundary value problems by fixed point methods, monotone iterative techniques and solution matching techniques. The two point boundary value problem for ordinary differential equation has an important role i...
Abstract Sulphuric acid is a backbone of chemical industry, agriculture and energy sectors. Tanzania has potential sources of producing its own sulphuric acid. The three most common methods: contact process, wet process and lead chamber process of producing sulphuric acid are reviewed. A modified lead chamber method can be a preferred method of producing the mineral acid by using local available raw materials according to Tanzania environment. Among of raw materials, pyrites from Samena area...
ABSTRACT The new exact solutions for the charged anisotropic stellar object were found by using Einstein-Maxwell field equations. In this study, the metric function, linear equation of state, and a new choice of the measure of anisotropy were used to formulate new quark star models. The field equations were transformed by adopting Bannerji and Durgapal transformation variables. The general differential equation governing the model was generated with the help of Einstein field equations, and ...
Abstract . New models for a charged anisotropic star in general relativity are found. We consider a linear equation of state consistent with a strange quark star. In our models a new form of measure of anisotropy is formulated; our choice is a generalization of other pressure anisotropies found in the past by other researchers. Our results generalize quark star models obtained from the Einstein-Maxwell equations. Well-known particular charged models are also regained. We indicate that relativ...
ABSTRACT Structural interpretation of Younger Granite complex of northern Nigeria using aeromagnetic and Landsat imagery was carried out to determine the depth to the magnetic basement, delineate the basement morphology and relief, delineate the structural features associated with the basin and to infer the influence of such structures on mineralization in the study area. Also, this study is aimed at determining the geothermal potentials of the area. The application of directional edge...
ABSTRACT Geo-environmental hazards associated with active and abandoned borrow pits are on the increase following rising trend in road construction. This situation presents a major challenge to Citizens, Environmentalists and Governments. Several highway failures have been directly linked to the action of erosion initiated by active or abandoned borrow pits situated close to roads. This study investigated environmental hazards and reclamation requirements associated with abandoned borrow ...
ABSTRACT Higher Learning Institutions worldwide have been depending highly on Information Technology for their business requirements and service delivery. They need substantial investment for procuring and maintaining software as well as hardware. Due to the growing needs and financial crisis, universities are facing challenges in acquiring high-performance computing facilities to support not only advanced analysis but also scientific researches. This study intended to develop a cloud comput...
ABSTRACT The use of ICT in education has been proved to be a key milestone in improving the learning process in different levels of education. To tap this opportunity, the government of Tanzania has implemented a number of projects aimed at introducing and using ICT in different levels of education. There have been similar initiatives in the private institutions as well. However, such initiatives have been facing different challenges particularly on the readiness of using ICT for education f...
ABSTRACT This Thesis investigates the nature of the parastrophs and derivatives of loops both of Bol-Moufang (Extra, Moufang, Central loops) and non Bol-Moufang (Conjugacy Closed loops) type in general. Extra loops is the case study. By using Fenyves (1968, 1969) definition of Extra loops and the results of Goodaire and Robinson (1982, 1990), this work shows that the parastrophs and derivatives of an Extra loop exist. Taking into consideration Ken Kunen (1996) results, it has been establishe...
