This chapter seeks to determine the optimal structural design parameter values for a 6-story controlled rocking steel braced frame (CRSBF) building that minimizes the upfront (initial construction) and earthquake-induced economic and environmental impacts. The dead load on the rocking frame, initial post-tensioning force, fuse strength and frame as...

... In this paper, we offer such diagnostic approach that based on a statistical analysis of read outcomes, that both detects and corrects faulty RFID software components that manifest in UHF tags and their EM surroundings. Our approach to this traditional monitoring study does not merely focus on how frequently RFID software can malfunction and how detrimental those malfunctions can be; rather, it emphasizes on how to detect and repair the malfunctions' impacts (Eze et al. 2019). This last point is frequently overlooked. ...
... Most of the assumptions were focused on perfect debugging that once a software product was checked against a wide range of data and fault is detected, it is instantly eliminated without causing any additional problems (Saraf and Iqbal 2019). The second assumption based on imperfect debugging presupposes that software products can reveal faults in it during testing, but definitely not the complete absence of it (Eze et al. 2019;Sushant et al. 2021;Tiwari and Sharma 2021). What this translates to is that though an RFID software is tested and the output is in amity with the specification, the software product may likely still contain some faults in it. ...
Apart from the widespread acceptance of the digital library as a major research response among university lecturers and students, little is known about the reliability of its RFID software (RFIDS), the challenges posed during software flaws, and the improvement strategies that can be used to maintain the RFID software reliability. The various NHPP software reliability growth models (SRGMs) to investigate the reliabilities of software products of this kind in real-world software development has not always been achieved because those studies were primarily concerned with modeling fault detection processes (FDP) and ignoring the fault correction processes (FCP). Here, we propose a reliability model of RFID software while keeping in mind the interdependence between fault quantities of the dual procedures of fault detection and fault correction. In evaluating the software reliability, fault introduction and testing coverage rates were eventually included to the parameters making our proposed model to be highly effective in estimating and forecasting the dependability of the software when compared with existing NHPP software reliability growth models (SRGMs).
... Computer-Assisted Instruction (CAI) is that instruction or learning that involves the use of a computer system, including any of the hardware, software, network and telecommunication efforts, for the primary purpose of learning, [14]. The CAI software after development must be tested by the quality assurance team to en-sure best quality, [15]. There are now several CAI packages on auto mechanics which could be used with power points, intelligent tutors, computer simulation, computer animation etc., [16] [17]. ...
A quasi experimental research design was adopted to compare competency-based learning and computer animation to determine their effect on academic achievement, retention and interest of students in auto mechanics. The pretest, posttest nonequivalent design was used. Six research questions were answered and four hypotheses were tested at 0.05 level of significance. Two technical colleges were used for the study. Population for the study was 115. Simple random sampling was used to assign school to treatment groups. No sampling was conducted in selection of students because intact classes were used. Auto mechanics Achievement Test (AMAT) and Auto mechanics Interest Inventory (AMII) were the instruments used for data collection. The data collected from the administration of the pretest and posttest was analyzed using Mean to answer the research questions while the hypotheses were tested at 0.05 level of significance using Analysis of Covariance (ANCOVA). The finding of the study revealed among others that students taught auto mechanics using compe-tency-based Learning technique had higher retention and interest and a higher score in the achievement test than students taught using computer animation technique. The hypotheses tested showed that p < 0.05 implying a significant difference in the effect of a competen-cy-based learning technique on the achievement score, retention score and interest of students taught auto mechanics. Based on the findings of the study, it was recommended that competency-based learning should be adopted for teaching of auto mechanics in the Technical Colleges since the course is project based.
Although school’s addition of web-based services to teaching and learning has increased, many effective quality systems to achieve replacement of software product due to software expansion and ageing has still not been well established. The primary objective of this study was therefore to develop a mathematical model for software developers advanced as potential breakthroughs in determining a replacement of ageing educational software products. This was a developmental case with retrospective review of software on maintenance for many years. The primary endpoint of such software was incidences of adverse breakdowns and malfunctions caused by system size, age, structure, incorrect, out of date documentation, complexity of the system and insufficient knowledge of the maintainer of the system. For comparison, data was generated from 2 software development firms to determine the rate of inflation, depreciation, salvage value and varying maintenance cost with the age of the software. The quality loss function was obtained to ascertain if software products are to continue undergoing maintenance process or a replacement. 84 software was developed within the 13years period of study. Their age mix ascertained. Findings revealed a sharp rise in year-wise development cost and a sharp reduction in year-wise cost of the salvage value of the software as they aged. Cost due to maintenance and repairs also vary with age and indicated a sharp rise in the fixed annual payment per year on the 10th year, an indication that software may be considered for replacement at the end of the 10th year based on the model. However, some common adverse effects of software failures due to age were noted. The requirement for this model for software developers therefore warrants further investigation into its applicability to achieve optimum economic life of software. Larger, comparative studies need to be performed with this model before its use can be routinely recommended to software development firms.KeywordsLearning-Based SoftwareModelQuality Lost FunctionSoftware maintenance
The need for teachers to understand basic properties of visual languages; as well as differentiate visual languages from other instructive counters like Visual Basic during classroom teaching of semantics specification of different visual languages prompted this study. We proposed a general framework which defined the abstract syntaxes and semantics of three selected notable visual languages with the aim of making comparisons of their syntaxes and semantics to address teacher’s confusion with other instructive counter example for visual programming languages which are under Microsoft Visual Studio. Our findings suggest the following (1) the framework affords the teachers both logical and denotational approach to understand and improve in their pedagogy of visual semantics and their properties, as well as improve their formal understanding about other instructive counter example for visual programming languages; (2) use of a notion of abstract visual syntax graph to explain the semantics of Visual Languages for proper understanding makes this work unique and this is how our work contribute to literature. Implications of these conclusions for education practice were discussed.KeywordsEuler circleSyntaxSemanticsShow and tellTeachersVEXVisual programming languages
