Abstract— Nowadays, we have access to unprecedented high-performance computing (HPC) resources that can be utilized to solve complex and computationally expensive optimization problem. However, one of the problems with existing metaheuristics algorithms is that they do not scale well. For example, particle swarm optimization (PSO) which is one of the most known metaheuristics performs poorly in terms of accuracy and convergence speed with large dimensional problems. In this paper, we propose a broadcast and distributed PSO using message passing interface (MPI) that showed to be faster and more accurate than the commonly utilized distributed master-slave version of PSO for the studied large-scale optimization problems.

Keywords- Particle swarm optimization; distributed computing; large scale optimization; big optimization.

Abstract— the software development industry considers quality a crucial factor in its development. Applying a certain level of standard to Software Quality (SQ) can help ensure customer satisfaction. This study primarily aims to define the different dimensions of SQ, identify the requirements for enhancing SQ, and present the challenges when SQ is restricted. The study also provides a review on the impact of quality and its measurement in the life cycle of software development. It examines the need for a quality standard to measure the increasing quality requirements and size of software. The findings of this study indicate an increasing need for high-quality software. Moreover, it provides a reference for other scholars regarding SQ testing and SQ in fuzzy logic.

Keywords- quality challenges; Software Development Life Cycle (SDLC); software measurement; software quality.

Abstract—A Mobile Ad-hoc Network (MANET) is a dynamic single or multi-hop wireless network where nodes are connected wirelessly, and the network is self-configured. Due to the high mobility of nodes, network topology changes more frequently and thus, routing becomes a challenging task. Several routing protocols have been proposed by the researchers for MANETs like the well-known Destination Sequenced Distance Vector (DSDV) and its variants. It is a table-driven routing protocol that was mainly proposed to solve routing loop problems and it performs very well in sparse and low mobility environments. However, it suffers from several performance issues when implemented on high and dense MANETs. A number of modifications of DSDV have been proposed to make it more adaptive and suitable for different environments. In this paper, the performance of DSDV, E-DSDV, I-DSDV, and O-DSDV routing protocols is compared. The performance metrics that were considered in this analysis are packet delivery ratio, throughput, End-to-End delay, and routing overhead. Several simulation scenarios were carried out using the Network Simulator tool (NS3) by varying the number of nodes, pause time and velocity. The simulation results have shown that I-DSDV outperforms the others in low mobility scenarios, whereas O-DSDV has the best performance in high velocity environments.

Keywords-MANET; DSDV; I-DSDV; E-DSDV; O-DSDV Simulation; Network Performance; NS3.

Abstract—Heart attack is one of the main causes of death nowadays especially for elderly people since it can strike anytime and anywhere. This project aims to build a smart assistant system that can predict the possibility of heart attack occurrence depending on the heartbeat rate before it happens for an elderly person wherever he/she is, and send a message to an elderly’s relative or a specialist informing him/her that the elderly might have a possible heart attack along with the geometric location in order to try to save the elderly’s life on time. In our system, a pulse sensor was attached to an Arduino microcontroller with ESP8266 NodeMCU as a Wi-Fi module to measure the heartbeat rate (BPM), if the heartbeat is either too low or too high, a message will be sent to a specified mobile, warning its owner of a possible heart attack. When the message arrives to the specified mobile, the owner will open an Android application named EPLSA. Through this application, he/she can send a request to the microcontroller asking for the geometric location. The microcontroller replies with the values of the latitude and longitude of the elderly’s location which can be viewed on Google maps too.

Abstract—   For   the   maintenance of concrete structures, cracks are an important indicator to   determine   the   repair priorities.   Until   a   few   years   ago,   it   was   visually   inspected   by   workers.   Recently,   the   crack   detection   methods   by using   image   analysis   have   been   proposed.   But,   the   methods   are   difficult   to   detect   the   cracks   on   the   concrete surface   with   unevenness   and   stains.   In   this   paper,   we   propose   a   crack   detection   method   using   V-shaped Features   and   propose   a   V-shaped   detector   for   detecting   V-shaped   Features.   The   V-shaped   detector   is   possible to   detect   cracks   with   a   high   degree   of   accuracy.   It   is   possible   to   perform   noise   processing   using   the   shape   and size   of   the   crack   detected   by   V-shaped   Features.   Several   experiments   were   carried   out   using   this   proposal method. As the results of the experiments, it was confirmed that cracks of 0.2 mm or less can be detected.

Abstract— Smartphones   are   now   an   integral   part   of   people’s   daily   life   activities   due   to   their   advanced   features. While   this   ostensibly   offers   great   convenience,   it   also   entails   great   psychological   challenges   due   to   the   constant ubiquity   of   information   to   which   users   are   exposed,   particularly   with   regard   to   work   environments.   Smartphones and   anytime,   anywhere   connectivity   have   caused   the   sphere   of   work   to   spill   over   into   the   realm   of   private   life,   and vice-versa.   This   study   explores   the   impact   of   using   smartphones   in   the   work   environment,   primarily   focusing   on Saudi   organizations   as   a   case   study   representative   of   developing   countries   with   high   smartphone   penetration. Open-ended   interviews   were   conducted   with   54   managers   from   different   organizations   in   Saudi   Arabia.   Analysis of    the    results    revealed    that    performance    and    regulations    were    the    main    factors    that    affected    the    use    of smartphone   in   work   environments,   which   is   helping   to   gain   a   better   understanding   of   current   challenges   facing many organizations.
