Assessment Of Quality Stability Of Composite Flours Produced By Dar Es Salaam Smes, Leonard Rweyemamu Dec 2014

Assessment Of Quality Stability Of Composite Flours Produced By Dar Es Salaam Smes, Leonard Rweyemamu

Tanzania Journal of Engineering and Technology (TJET)

A study was conducted to assess quality stability of cereal flours processed by food processing SMEs in Dar es Salaam. This product is obtained by mixing various cereal grains and is considered as of higher nutritional values in Tanzania. The shelf-life was predicted by determining water activity (aw) and moisture content (MC) levels and plotting the water sorption isotherms (MSI). Ninety per cent of investigated samples (N=78) were found packaged in the materials of various quality conditions. It was found that the packaging materials mostly used is plastic films (63%), paper packets/bags (26%), hard papers (3%), plastic jars (1%) and …


Application Of Trip Generation Models For Urban Transport Planning In A Data Scarce Developing Country City: The Case Of Dar Es Salaam, Hannibal Bwire Dec 2014

Application Of Trip Generation Models For Urban Transport Planning In A Data Scarce Developing Country City: The Case Of Dar Es Salaam, Hannibal Bwire

Tanzania Journal of Engineering and Technology (TJET)

With the increase in travel demand and traffic management problems in many developing countries cities, travel demand forecasting models are being employed increasingly to make informed decisions about the operational improvements to the existing transportation system and the design and performance of future transportation systems. The main advantage of using travel demand forecasting models for such purposes is that they are capable of capturing the interactive effects of different components of the system under study. However, for some time now there have been concerns about the application of transport planning models in developing countries. The concerns have been mainly in …


Observability-In-Depth: An Essential Complement To The Defense-In-Depth Safety Strategy In The Nuclear Industry, Francesca Favaro, Joseph Saleh Dec 2014

Observability-In-Depth: An Essential Complement To The Defense-In-Depth Safety Strategy In The Nuclear Industry, Francesca Favaro, Joseph Saleh

Faculty Publications

Defense-in-depth is a fundamental safety principle for the design and operation of nuclear power plants. Despite its general appeal, defense-in-depth is not without its drawbacks, which include its potential for concealing the occurrence of hazardous states in a system, and more generally rendering the latter more opaque for its operators and managers, thus resulting in safety blind spots. This in turn translates into a shrinking of the time window available for operators to identify an unfolding hazardous condition or situation and intervene to abate it. To prevent this drawback from materializing, we propose in this work a novel safety principle …


Security Analysis On Network Systems Based On Some Stochastic Models, Xiaohu Li Dec 2014

Security Analysis On Network Systems Based On Some Stochastic Models, Xiaohu Li

LSU New Orleans Theses and Dissertations

Due to great effort from mathematicians, physicists and computer scientists, network science has attained rapid development during the past decades. However, because of the complexity, most researches in this area are conducted only based upon experiments and simulations, it is critical to do research based on theoretical results so as to gain more insight on how the structure of a network affects the security. This dissertation introduces some stochastic and statistical models on certain networks and uses a k-out-of-n tolerant structure to characterize both logically and physically the behavior of nodes. Based upon these models, we draw several illuminating results …

Experimental And Numerical Investigation Of The Mechanism Of Blast Wave Transmission Through A Surrogate Head, Yi Hua, Praveen Akula, Linxia Gu, Jeff Berg, Carl A. Nelson Jul 2014

Experimental And Numerical Investigation Of The Mechanism Of Blast Wave Transmission Through A Surrogate Head, Yi Hua, Praveen Akula, Linxia Gu, Jeff Berg, Carl A. Nelson

Department of Mechanical and Materials Engineering: Faculty Publications

This work is to develop an experiment-validated numerical model to elucidate the wave transmission mechanisms through a surrogate head under blast loading. Repeated shock tube tests were conducted on a surrogate head, i.e., water-filled polycarbonate shell. Surface strain on the skull simulant and pressure inside the brain simulant were recorded at multiple locations. A numerical model was developed to capture the shock wave propagation within the shock tube and the fluid-structure interaction between the shock wave and the surrogate head. The obtained numerical results were compared with the experimental measurements. The experiment-validated numerical model was then used to further understand …


Application Of Remotely Sensed Rainfall Data In Rainfall-Runoff Modelling. A Case Of Pangani River Basin, Tanzania, Joel Nobert Jun 2014

Application Of Remotely Sensed Rainfall Data In Rainfall-Runoff Modelling. A Case Of Pangani River Basin, Tanzania, Joel Nobert

Tanzania Journal of Engineering and Technology (TJET)

Rainfall runoff modelling in a river basin is vital for number of hydrologic application including water resources assessment. However, rainfall data from sparse gauging stations are usually inadequate for modelling which is a major concern in Tanzania. This study presents the results of comparison of Tropical Rainfall Measuring Mission (TRMM) satellite rainfall products at daily and monthly time-steps with ground stations rainfall data; and explores the possibility of using satellite rainfall data for rainfall runoff modelling in Pangani River Basin, Tanzania. Statistical analysis was carried out to find the correlation between the ground stations data and TRMM estimates. It was …


Noise Pollution In Maize Milling Smes, Erasto Elias Jun 2014

Noise Pollution In Maize Milling Smes, Erasto Elias

Tanzania Journal of Engineering and Technology (TJET)

Maize milling SMEs emit high levels of noise which can have adverse effects on human beings and therefore require controlling. This paper reports on a study that involved assessment and measurement of noise level in maize milling SMEs in DSM and Morogoro urban, gathering opinions of workers and the neighbouring population on noise problems, and suggesting solutions for noise control. Noise measurements in 41 SMEs were recorded from 89-103 dBA in DSM and 92-103 dBA in Morogoro near the milling machines. These values were higher than the safe level of 85 dBA for 8 hours working shift. Measurement also indicated …


Lemongrass And Cinnamon Essential Oils As Vitamin C Preservatives And Flavour Enhancers In Jam, Denice Byarushengo Jun 2014

Lemongrass And Cinnamon Essential Oils As Vitamin C Preservatives And Flavour Enhancers In Jam, Denice Byarushengo

Tanzania Journal of Engineering and Technology (TJET)

Lemongrass and cinnamon essential oils (LEO and CEO) are natural oils with high anti oxidation capacity, pleasant flavour, and various health benefits. Their ability to preserve vitamin C and flavour in jam have not been tested. In this study the performance of two essential oils (EOs) in preserving vitamin C and improving jam flavour were investigated. The EOs were produced by hydro-steam distillation of fresh lemongrasses and cinnamon leaves using a Clevenger apparatus. Jam samples were dosed with various concentrations of either single or mixed EOs and then stored at either room or refrigeration temperature. Samples were analysed for changes …

Accuracy Of Dem-Based Topographic Data In Flood Inundation Modelling: A Case Of Wami River, Tanzania, Preksedis Ndomba

Tanzania Journal of Engineering and Technology (TJET)

Ihe objective of this Biper is to evaluate and further convnent on the accuracy of the DEW- based topographic data us input in flood mchdelling. Recent studies have indicated that hydraulic of the modified sections based on high resolution are geometrically and hydraulically similar to the measured ones, In the study hydraulic modelling intended to guide a developnent project whereby a protection embankment is contemplated. Therefore, accuracy in terns of positioning/alignment of natural features such as river banks and heights/elevarions was imperative m arrain. In order m achieve these, accuracy of various topographic data sources were qualitatively and/or quantitatively before …
