Prototypes have become an essential aspect of the development process in software processes. are used to generate ideas and test them with speed flexibility accepting changing requirements throughout system’s life cycle. They constitute a clear difference dealing agile processes effectively addressing fluctuating through continuous cooperation between developers users. allow collect feedback from stakeholders early, ensuring that their expectations for final product met. also testing...

Agile development methodologies are becoming increasingly popular in agile projects due to their iterative nature and adaptability. The Monte Carlo method is distinguished by its statistical technique of using random samples obtain many satisfactory results for solving uncertainty. It can be used software building different scenarios measuring impact on the project through operations. Its ability meet significant challenges managing risk uncertainty mitigation. In this study, we propose a...

Abstract In this paper, we compare two methods of subspace blind channel estimation in orthogonal frequency division multiplexing (OFDM) systems using different guard intervals under a multi-path with an exponentially decaying power profile. both methods, propose the same solution to solve scalar ambiguity problem, which is common problem by single pilot signal. The bit error rate (BER) and normalized mean square (NMSE) estimated vector were compared various signal-to-noise ratio (SNR)...

In software development processes, there is a clear challenge to the application of danger organization in projecting organization, especially integration with understanding requirements and discussions during developing procedure. Though, benefit applying interaction risk management tools project tasks very good reducing losses, when reviewing risks practices identifying for each assignment.Here, scheme functions theory are discussing, interrelationships, development. Where we focus on...

Wireless sensor network (WSN) security is an important component for protecting data from attacker. For improving security, cryptography technologies are divided into two kinds: symmetric and asymmetric. Therefore, the implementation of protocols generating a secret key takes long time in comparison to sensor’s limitations, which decrease throughput because they based on asymmetric method. The algorithms complex throughput. In this paper, encryption wireless networks proposed. work, 24...

In Multi-core systems, dynamic page management is a vital and also important issue. For access to local memories, each primary memory source distributable. The number of processes related the amount utilized memory. Consequently, poor managements cause fundamental problems performance adjustments. this article, distributed manager based on accelerated microcode introduced present allocator systems. This has scalability its agenda. enjoys an accelerator provides application programming...

E-learning has become a popular learning method used in many local and international universities educational institutions. The initial achievements of e-learning platforms the online environment demonstrated outstanding advantages distance education. However, it is necessary to conduct an evaluation process, particular effective assessment via online-based platforms. Where this study aimed identify effectiveness from point view teaching staff Technical Institute Babel Al-Mussaib. To achieve...

At present, E-learning has become a common learning method used in many local and international universities due to the Covid-19 pandemic. So Many academic staff have been allowed go as an effective way continue educational process times of crisis. This paper investigates effectiveness difficulties use from perspective students at “Babylon Technical Institute, Al-Furat Al-Awsat University”, Iraq. In this study, Google Forms was designing questionnaires spread Coronavirus disease (COVID-19)...

This article describes the development of a design tool that provides ability to manage quickly create prototypes solutions, including graphical elements and software components are connected together. At same time, this should be universal suitable for use in various projects.
