Item Comparison of Sorting Algorithms(ALNEELAIN UNIVERSITY, 2014) hiba Mohamed sulieman saliemAbstract There are many methods have been developed to arrange the array values in various ways for a database cold the sorting algorithms. The classification of sorting algorithms base on System complexity of computational, terms of number of swaps, Memory usage Stability of sorting algorithms . In this researsh we seek to detemiine the efficiency of the various sorting algorithms according to the time and number of swaps by using randomized trails. The build environment using the Java language. We represents these sorting algorithms bubble sort, selection sort, insertion, sort quick sort and merge sort as a way to sort an array or integers and run random trails of length. I created a package called “sorting” to execute a sort, it provided module of sorting list(Non decreased &decreased) uses different method of sorting ,the amount of swaps of each sorting algorithm and the runtime (in millisecond) and I found a quick sort is the fastest algorithm compare to Bubble sort, Insertion sort, Selection sort, and merge sort.Item performance Evalution of (AODV AND OLSR)Routing protocols Under the lmpact of Black hole Attack(AlNEElAN UNVERSLTY, 2018) Dalal omer sida hmed HagaliItem performance Analysis of WDMln optical Networks(AlNEElAN UNVERSLTY, 2018-09) Fathia zein Elabadeen mohammed khalf AllahItem QUality of services of voice overlp over LTE(AlNEElAN UNVERSLTY, 2018) Ashraf Ahmed Hassan omerItem performance Evaluation of (AODV and olsr)Routing protocols under the lmpact of black hole Attaclc(AlNEElAN UNVERSLTY, 2018-11) Dalal omer sida hmed HagaliItem preformation Evalu ation of ofdm Network(AlNEElAN UNVERSLTY, 2018-09) Sumia Yassin EbiadItem Using Artificial Neural Networks to predict protein secon dary structure(AlNEElAN UNVERSLTY, 2018-09) Tagwa Abdallah mohamed Abu -BakrItem Performance Analysis of Different Scheduling Processor Based for Real Time Systems(ALNEELAIN UNIVERSITY, 2019-04) Nahid Mohammed Issa GhanawaAbstract:- Process scheduling selects from among the processes that are ready (in ready queue) to execute so the CPU can be allocated to one of them. CPU scheduling is important because when we have multiple runnable processes, it can have a big effect on resource utilization and the overall perfonnance of the system. this project discussed three types of non- preemptive scheduling algorithms, first come first served (FCFS), shortest job first(SJF) scheduling and priority scheduling to compare their efficiency perfonnance in terms of: average waiting time, average turnaround time, utilization and throughput. The objective is to know which algorithm is more suitable for a certain process. Many tasks were performed by the three algorithms, and we obtained a set of results fiom samples were taken. noticed that they were close together, so average results for 1000 samples was taken to get more accuracy. It was found that the best algorithm is SIF , F CF S algorithm is better for processes that have a longer processing time, and priority is better in cases where tasks are sorted according to their priority.Item DESIGN AND IMPLEMENTATION OF A LOW-COST EMBEDDED OXIMETER(Al-Neelain University, 2014-06) REEM ABDELMONIAM ISMAILABSTRACT This thesis presents the design and implementation of a low-cost embedded Oximeter for real-time measurement of arterial oxygen and heart beat rate monitoring using wireless transmission. The design requirements include low cost, small size, light weight, and a wireless communication capability. The proposed design is based on a microcontroller system Atmega32, responsible for generating two non-overlapping square waves used for driving its LEDs. It also has a built-in USART which makes communication easy with PC/Laptop. An ADC is used to convert the signal from Photodiode to digital format, sampling the digital optical signal from Photodiode to calculate (SpO2 and heartbeat rate HR). The Embedded Software was written in C using Codevision AVR for the ATmega processor where Proteus software is used for simulation. The user interface is built in LabVIEW visual programming environment with real-time display of SpO2 and HR, Sofiware for the system provides a mechanism to configure the system according to administrator requirements. The proposed tools enable biomarker parameters to be viewed and managedItem Enhanced model for Usability Requirements D 7 Elicitation(AL-Neelain University, 2015) Elsiddig Khogly Elsiddig KhoglyIntroduction: Usability is one of the most important aspects of requirement engineering .The HCI community has developed guidelines and recommendations for improving the usability system that are usually applied at the last stages of the sofiware development process. On the other hand, the software engineering community has developed methods to elicit functional requirements in the early stages, but usability has been relegated to the last stages together with other non- functional requirements. Therefore. there are no methods of usability requirements elicitation to develop software within both communities. This thesis details a framework that looks at how to deal with certain usability features in the early software development stages. A Model contains five steps that should be achieved in order to elicit the usability requirement as the non-functional requirement. A case study has been conduct to test and evaluate the proposed method. Results indicate that such model will aids to increase the developer's awareness toward usability and there for better usability feature and higher user satisfaction could be accomplished. Methods: A survey study (Questionnaire and interview) has been used to study and investigate a particular community (Developers) also SPSS version 2] has been used to analyze the data of the Questionnaire. Results: this result was reached by the survey study and found that (88.4%) of the sample under study (Developers) haven’t any specific guidelines to deal with NFRs and especially usability. The evaluation was conducted to the proposed model is testament to how important guidelines of usability and the difference is clear and visual between the system in the first level and the second level. The proposed an approach for elicitation process helped to elicit usability requirements and less time consuming way to identify usability functionality. Discussion: There are some limitations related to Requirements Engineering knowledge spicily the requirement type and method to elicit it and Human-Computer Interaction (HCI). Also Companies that develop software system and developer have less method to elicit usability requirement as non-functional requirement and there is no specific guidelines to deal with non-functional requirements especially usability requirements.
