Object Oriented Application Paradigms and Software Development Processes

Authors: Girma Yohannis Bade, Fetenech Meskele

Abstract-The origin of the OOSE in evaluation and design of the software has expanded much and is now considered as one of the software integration processes. The Object Oriented Software Development is a set of the Object Oriented Analysis (OOA) models, Object Oriented Design (OOD) and the Object Oriented Programming (OOP) which provide powerful framework for development of the software. The main goal of the OOSE is the increasing the reusability capacity of the software, reducing the complexity and the software systems maintenance costs. This paper discuss Object oriented application paradigms and software development process. The application paradigms are specification, analysis and design, programming, and user interfaces which also consists software developmental processes like requirement specification, system analysis, design, implementation, deployment and maintenances. In both case class and object play a central role to ensure that software development is object oriented.

Surface Water and Groundwater Resources of Rift Valley Lakes Basin of Ethiopia: A Review of Potentials, Challenges and Future Development Perspectives

Authors: Ermias Mekonnen

Abstract- In this paper, a critical review of recent studies on surface water and groundwater resources potentials as well as the challenges and future development perspectives in the rift valley lakes basin of Ethiopia was conducted. The basin is endowed with a number of rivers as well as lakes of varying size with high environmental significance. The total surface water resource of the rift valley lakes basin is estimated at just over 5.6 billion m3/year and the estimated groundwater potential of the basin is 0.10 billion m3/year. The potential irrigable land of the basin is only 2.64%; and the gross hydro-electric potential of the basin is found to be 800Gwh/year. The water resources of the basin have enough potential for irrigation, hydropower and domestic water supply. However, these potentials are not fully utilized and translated into development because of many factors including limited financial resources, technical challenges, climate variability and lack of good governance in the water sector. As a result, attention must be given to interventions that moderate hydrological variability, mitigate the physical impacts of hydrologic shocks on the environment and watersheds, and arrest land degradation. Therefore, this review paper attempts to explore the interventions like infrastructure investments to provide storage and regulate river flows and runoff, and land and soil management practices to enhance the natural capacity of watersheds to moderate hydrology.

Review o n Design & Investigation o f Automobile Disc Brake System

Authors: Nayan Dey, Dr. Purnima Shukla

Abstract- Multiple system has been studied and developed in order to meet safety requirements. Instead of having air bag, good suspension systems, good handling and safe cornering, there is one most critical system in the vehicle which is brake systems. Without braking system in a vehicle will put passengers in unsafe position. Therefore, it’s must for all vehicles to have proper braking system. Braking is a process which converts the kinetic energy of vehicle into mechanical energy. The disc brake is a device used to de-accelerate or stop the rotation of wheel. A brake disc or rotor usually made of cast iron or ceramic composite, is connected to the wheel. Friction material of brake pad mounted on a device called a brake calliper is forced by the action of mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc to stop the wheels. It’s important to understand action force and friction force on the disc brake with new material for the investigation how disc brake works more efficiently, which can help to reduce heat generation and provide better tribological results.

Wave Breaking Co-efficient and Digha Coastal Beach Profile

Authors: GirmNayan Dey, Dr. Purnima Shukla

Abstract-Wave properties are important influencer to tune the beach profile. And also beach profile controls the wave nature such as breaker type. Both wave properties and beach longitudinal profile organize each other through a balance. The said research paper is traced this incidents with evidence in Digha coastal beach. Through this paper, longitudinal beach profile and breaker type and their relationship have been sketched. To analyse the breaker type several parameters have been used, viz. beach slope (β), depth of water (d), wave period (T), Breaker height (Hb) and time between two successive waves (Δt). Breaker type configurations may vary between offshore (B0) and onshore (Bb) beach platform. Offshore breaker type is important for beach surfing zone.

New Trend of Leaching of Silicate and Sulfide Minerals

Authors: Dr. Tarek Abdel Wahab Ali El Barbary

Abstract-Although ore processing is an old technique, it is the technique that used to treat sulfide or silicate ores, a traditional and prevalent technique. Silicate ores as kaoline, clay, feldspare, nepheline syanite, silica sand, quartz, talc and zircon are treated with thermal melt. While sulfide ore as chalcopyrite, pyrite treated with thermal melt. But now a day facing challenge through new mineral hydrotherapy processes.
