Impacts of the Tanzanian 2013 - 2017 Glide path Implementation Phase on Telecom Voice Call pricing[ ]


The effects of reduction in mobile termination rates (MTR) on voice call pricing trends and mobile telecom market competitiveness in the Tanzanian for the third phase of glide path were evaluates using Tanzanian quarterly telecommunication statistical reports for year 2013 to 2018. The results reviled general increasing trends for prepaid voice calls prices for all mobile network operators (MNOs) in Tanzania as compared to that of 2013. Comparing pricing trends among major MNOs, the results indicated convergence of on-net and off-net prices at the end of year 2018.

Aspects on Modeling of Hydro-Turbine Speed Governor[ ]


The liberalization of the electricity market enforces the use of more productive and energy efficient technologies. Hence, the revitalization of some parts of the equipment in the existing power systems was required. Such a need is imposed on hydro-turbine speed governors. Governor play an important role in hydraulic turbine. It maintains the stability of the system frequency by controlling the speed of the system. The paper analyzes the standard control algorithm for turbine governors, the PID controller. The fundamental basics of PID controllers are illustrated, methods of tuning are considered in order to demonstrate the adaptation of these devices to the system, but also their limitations are highlighted. Finally, alternative control systems are also considered.

Reliable Route Discovery using Link Break Prediction Multicast Routing in MANET[ ]


In MANETs, there are several crucial problems like energy consumption, QoS (Quality of Service), exposure to attacks, link stability, etc. that require to be addressed for improved communication. ‘Link Stability’ or ‘Reliable path’ is important because radio links are likely to be unreliable due to node mobility. To extend the link stability, we need to solve the problem of link breakages in the networks. Because these link breakage problem causes high data loss and delay. In order to resolve these problems, the concept of link breakage prediction has appeared. In this dissertation, we have proposed a link breakage prediction algorithm.

Mechanical behaviors of joining AL-Alloys based FSW parameters and welding tool design[ ]


Friction Stir Welding is a solid-state welding process with specially rotating tool design. The heat is generated due to the friction between the workpiece-surface and the tool shoulder. The core benefit of FSW joint is to weld the material without achieving the fusion temperature so it’s allows to join almost types of aluminum alloys, even the ones categorized as non-weld able alloy by the traditional welding process such as fusion welding because of the hot cracking and unfortunate solidification microstructure in the welding zone. FSW is used in aerospace, automotive, marine industries, electronics etc.

STUDY OF GLACIAL LAKE OUTBURST FLOODS AND METHODS TO PREVENT THEIR EFFECTS[ ]


Glacial lakes are common in the high elevation of glacierized basin. They are formed when glacial ice or moraines impound water. These lakes normally drain their water through seepage in front of the retreating glacier. Flash floods caused by the outburst of glacial lakes, called as Glacial Lake Outburst Flood (GLOF), are well known in Himalayan terrain, where such lakes are formed due to landslides.

Beauty of Agrivoltaic System regarding double utilization of same piece of land for Generation of Electricity & Food Production[ ]


In order to meet global energy demands with clean renewable energy such as with solar photovoltaic (PV) systems, large surface areas are needed because of the relatively diffuse nature of solar energy. Much of this demand can be matched with aggressive building integrated PV and rooftop PV, but the remainder can be met with land-based PV farms. Using large tracts of land for solar farms will increase competition for land resources as food production demand and energy demand are both growing and vie for the limited land resources. Land competition is exacerbated by the increasing population.

Evolving Role of Space Actors: from Space race 1.0 to 2.0 and a Model for Developing Economies[ ]


Space technology evolution continues to steadily draw inspiration from the private business sector. With older national space agencies changing their modus operandi towards outsourcing more of their activities, private companies that have come to be termed “new space” are stepping into the shoes left behind by the bigger government monopolies that participated in the first space race (1.0). This new paradigm is aimed at creating efficiencies in the end-to-end chain of space exploration activities such that governments can focus on the core aspects of space utilization while private space companies can provide needed services that support the work of governments.

THE INCIDENCE, PREVALENCE, AND PATHOGENESIS OF MONOGENIC DIABETES SYNDROME[ ]


Monogenic diabetes syndromes result from a mutation of a single gene involved in the regulation of pancreatic beta-cell function. It is a rare condition, accounting for 1-4% of all paediatric diabetes cases. This gene defect is usually inherited, either autosomal or recessive, but a small percentage of spontaneous mutations have been found. There are over 40 subtypes of genetic mutations identified, each with its unique phenotypical characteristics (Rubio-Cabezas et al., 2014). Overall, it can be subdivided into two main categories: Maturity onset diabetes of the Young (MODY) and Neonatal diabetes (NDM). This report will discuss the incidence, prevalence, and pathogenesis of the MODY and NDM syndromes.

REPLACEMENT OF CEMENT WITH SILICA FUME WITH ADDITION OF JUTE FIBER[ ]


The concrete is widely used construction material in the world. In conventional concrete, micro-cracks develop before structure is loaded because of drying shrinkage and other causes of volume change. When the structure is loaded, the micro cracks open up and propagate because of development of such micro-cracks, results in inelastic deformation in concrete. It has been recognized that the addition of small, closely spaced and uniformly dispersed fibers to the concrete would act as crack arrester and would substantially improve its compressive and split tensile strength properties. In this research, Natural available Jute fibers
