The proficiency testing results from 2013 to 2017 were analyzed to determine laboratories that were consistent in reporting quality results and those that had difficulty in doing so. Methods: A panel of twenty cultures were sent out to each of these laboratories. The laboratories were expected to grow the cultures in their own laboratories, set up drug susceptibly testing by all the methods they were certified for and report the results within the stipulated time period. The turnaround time for reporting results, specificity, sensitivity positive and negative predictive values and efficiency of the laboratory in identifying the cultures were analyzed. Results: Most of the laboratories had reported their results within the stipulated time period. However, there was enormous delay in reporting results from few of the laboratories. This was mainly due to improper functioning of the biosafety level III laboratory. Only 40% of the laboratories had 100% efficiency in solid culture using Lowenstein Jensen medium. This was expected as a solid culture, and drug susceptibility testing is not used for diagnosing drug resistance. Rapid molecular methods such as Line probe assay and Genexpert are used to determine drug resistance. Automated liquid culture system such as the Mycobacterial growth indicator tube is used to determine prognosis of the patient while on treatment. It was observed that 90% of the laboratories had achieved 100% in the liquid culture method. Almost all laboratories had achieved 100% efficiency in the line probe assay method which is the method of choice for determining drug-resistant tuberculosis. Conclusion: Since the liquid culture and line probe assay technologies are routinely used for the detection of drug-resistant tuberculosis the laboratories exhibited higher level of efficiency as compared to solid culture and drug susceptibility testing which are rarely used. The infrastructure of the laboratory should be maintained properly so that samples can be processed safely and results could be declared on time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=annual%20proficiency%20testing" title="annual proficiency testing">annual proficiency testing</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20susceptibility%20testing" title=" drug susceptibility testing"> drug susceptibility testing</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediate%20reference%20laboratory" title=" intermediate reference laboratory"> intermediate reference laboratory</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20reference%20laboratory" title=" national reference laboratory"> national reference laboratory</a> </p> <a href="https://publications.waset.org/abstracts/82990/analysis-of-the-annual-proficiency-testing-procedure-for-intermediate-reference-laboratories-conducted-by-the-national-reference-laboratory-from-2013-to-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82990.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5107</span> Challenges in Experimental Testing of a Stiff, Overconsolidated Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Konstadinou">Maria Konstadinou</a>, <a href="https://publications.waset.org/abstracts/search?q=Etienne%20Alderlieste"> Etienne Alderlieste</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Peccin%20da%20Silva"> Anderson Peccin da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Arntz"> Ben Arntz</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20van%20der%20Bijl"> Leonard van der Bijl</a>, <a href="https://publications.waset.org/abstracts/search?q=Wouter%20Verschueren"> Wouter Verschueren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shear strength and compression properties of stiff Boom clay from Belgium at the depth of about 30 m has been investigated by means of cone penetration and laboratory testing. The latter consisted of index classification, constant rate of strain, direct, simple shear, and unconfined compression tests. The Boom clay samples exhibited strong swelling tendencies. The suction pressure was measured via different procedures and has been compared to the expected in-situ stress. The undrained shear strength and OCR profile determined from CPTs is not compatible with the experimental measurements, which gave significantly lower values. The observed response can be attributed to the presence of pre-existing discontinuities, as shown in microscale CT scans of the samples. The results of this study demonstrate that the microstructure of the clay prior to testing has an impact on the mechanical behaviour and can cause inconsistencies in the comparison of the laboratory test results with in-situ data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boom%20clay" title="boom clay">boom clay</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20testing" title=" laboratory testing"> laboratory testing</a>, <a href="https://publications.waset.org/abstracts/search?q=overconsolidation%20ratio" title=" overconsolidation ratio"> overconsolidation ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-strain%20response" title=" stress-strain response"> stress-strain response</a>, <a href="https://publications.waset.org/abstracts/search?q=swelling" title=" swelling"> swelling</a>, <a href="https://publications.waset.org/abstracts/search?q=undrained%20shear%20strength" title=" undrained shear strength"> undrained shear strength</a> </p> <a href="https://publications.waset.org/abstracts/144267/challenges-in-experimental-testing-of-a-stiff-overconsolidated-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5106</span> Estimation of Uncertainty of Thermal Conductivity Measurement with Single Laboratory Validation Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saowaluck%20Ukrisdawithid">Saowaluck Ukrisdawithid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thermal conductivity of thermal insulation materials are measured by Heat Flow Meter (HFM) apparatus. The components of uncertainty are complex and difficult on routine measurement by modelling approach. In this study, uncertainty of thermal conductivity measurement was estimated by single laboratory validation approach. The within-laboratory reproducibility was 1.1%. The standard uncertainty of method and laboratory bias by using SRM1453 expanded polystyrene board was dominant at 1.4%. However, it was assessed that there was no significant bias. For sample measurement, the sources of uncertainty were repeatability, density of sample and thermal conductivity resolution of HFM. From this approach to sample measurements, the combined uncertainty was calculated. In summary, the thermal conductivity of sample, polystyrene foam, was reported as 0.03367 W/m·K ± 3.5% (k = 2) at mean temperature 23.5 °C. The single laboratory validation approach is simple key of routine testing laboratory for estimation uncertainty of thermal conductivity measurement by using HFM, according to ISO/IEC 17025-2017 requirements. These are meaningful for laboratory competent improvement, quality control on products, and conformity assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20laboratory%20validation%20approach" title="single laboratory validation approach">single laboratory validation approach</a>, <a href="https://publications.waset.org/abstracts/search?q=within-laboratory%20reproducibility" title=" within-laboratory reproducibility"> within-laboratory reproducibility</a>, <a href="https://publications.waset.org/abstracts/search?q=method%20and%20laboratory%20bias" title=" method and laboratory bias"> method and laboratory bias</a>, <a href="https://publications.waset.org/abstracts/search?q=certified%20reference%20material" title=" certified reference material"> certified reference material</a> </p> <a href="https://publications.waset.org/abstracts/115436/estimation-of-uncertainty-of-thermal-conductivity-measurement-with-single-laboratory-validation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115436.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5105</span> Effect of Open-Ended Laboratory toward Learners Performance in Environmental Engineering Course: Case Study of Civil Engineering at Universiti Malaysia Sabah</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Bolong">N.

With current drives of new technology resources and evolving era of education methods, renewal status of learning and teaching in laboratory methods are in progress, for both learners and the educators. To enhance learning outcomes in laboratory works particularly in engineering practices and testing, learning via hands-on by instruction may not sufficient. This paper describes and compares techniques and implementation of traditional (expository) with open-ended laboratory (problem-based) for two consecutive cohorts studying environmental laboratory course in civil engineering program. The transition of traditional to problem-based findings and effect were investigated in terms of course assessment student feedback survey, course outcome learning measurement and student performance grades. It was proved that students have demonstrated better performance in their grades and 12% increase in the course outcome (CO) in problem-based open-ended laboratory style than traditional method; although in perception, students has responded less favorable in their feedback. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering%20education" title="engineering education">engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=open-ended%20laboratory" title=" open-ended laboratory"> open-ended laboratory</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20engineering%20lab" title=" environmental engineering lab"> environmental engineering lab</a> </p> <a href="https://publications.waset.org/abstracts/13413/effect-of-open-ended-laboratory-toward-learners-performance-in-environmental-engineering-course-case-study-of-civil-engineering-at-universiti-malaysia-sabah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5104</span> Automated Java Testing: JUnit versus AspectJ</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manish%20Jain">Manish Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Gopalani"> Dinesh Gopalani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Growing dependency of mankind on software technology increases the need for thorough testing of the software applications and automated testing techniques that support testing activities. We have outlined our testing strategy for performing various types of automated testing of Java applications using AspectJ which has become the de-facto standard for Aspect Oriented Programming (AOP). Likewise JUnit, a unit testing framework is the most popular Java testing tool. In this paper, we have evaluated our proposed AOP approach for automated testing and JUnit on various parameters. First we have provided the similarity between the two approaches and then we have done a detailed comparison of the two testing techniques on factors like lines of testing code, learning curve, testing of private members etc. We established that our AOP testing approach using AspectJ has got several advantages and is thus particularly more effective than JUnit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspect%20oriented%20programming" title="aspect oriented programming">aspect oriented programming</a>, <a href="https://publications.waset.org/abstracts/search?q=AspectJ" title=" AspectJ"> AspectJ</a>, <a href="https://publications.waset.org/abstracts/search?q=aspects" title=" aspects"> aspects</a>, <a href="https://publications.waset.org/abstracts/search?q=JU-nit" title=" JU-nit"> JU-nit</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title=" software testing"> software testing</a> </p> <a href="https://publications.waset.org/abstracts/82341/automated-java-testing-junit-versus-aspectj" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5103</span> Verification of Space System Dynamics Using the MATLAB Identification Toolbox in Space Qualification Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuri%20V.%20Kim">Yuri V.

It can be considered as a generic test and used for a wide class of SS that from the point of view of System Dynamics and Control may be described by the ordinary differential equations. Suggested methodology is based on using semi-natural experiment- laboratory stand that doesn’t require complicated, precise and expensive technological control-verification equipment. However, it allows for testing system as a whole totally assembled unit during Assembling, Integration and Testing (AIT) activities, involving system hardware (HW) and software (SW). The test physically activates system input (sensors) and output (actuators) and requires recording their outputs in real time. The data is then inserted in laboratory PC where it is post-experiment processed by Matlab/Simulink Identification Toolbox. It allows for estimating system dynamics in form of estimation of system differential equations by the experimental way and comparing them with expected mathematical model prematurely verified by mathematical simulation during the design process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics" title="system dynamics">system dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20system%20ground%20tests%20and%20space%20qualification" title=" space system ground tests and space qualification"> space system ground tests and space qualification</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics%20identification" title=" system dynamics identification"> system dynamics identification</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite%20attitude%20control" title=" satellite attitude control"> satellite attitude control</a>, <a href="https://publications.waset.org/abstracts/search?q=assembling" title=" assembling"> assembling</a>, <a href="https://publications.waset.org/abstracts/search?q=integration%20and%20testing" title=" integration and testing"> integration and testing</a> </p> <a href="https://publications.waset.org/abstracts/137789/verification-of-space-system-dynamics-using-the-matlab-identification-toolbox-in-space-qualification-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137789.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5102</span> Application of Optical Method Based on Laser Devise as Non-Destructive Testing for Calculus of Mechanical Deformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Da%C3%AFra">R.

Anthrax is a zoonotic disease that is also well-recognized as a potential agent of bioterrorism. Infection in humans is extremely rare in the developed world and is generally due to contact with infected animals or contaminated animal products. Testing of this zoonotic disease began in 1907 in Georgia and is still being tested routinely to provide accurate information and efficient testing results at the State Laboratory of Agriculture of Georgia. Each clinical sample is analyzed by RT-PCR and bacteriology methods; this study used Real-Time PCR assays for the detection of B. anthracis that rely on plasmid-encoded targets with a chromosomal marker to correctly differentiate pathogenic strains from non-anthracis Bacillus species. During the period of 2015-2022, the State Laboratory of Agriculture (SLA) tested 250 clinical and environmental (soil) samples from several different regions in Georgia. In total, 61 out of the 250 samples were positive during this period. Based on the results, Anthrax cases are mostly present in Eastern Georgia, with a high density of the population of livestock, specifically in the regions of Kakheti and Kvemo Kartli. All laboratory activities are being performed in accordance with International Quality standards, adhering to biosafety and biosecurity rules by qualified and experienced personnel handling pathogenic agents. Laboratory testing plays the largest role in diagnosing animals with anthrax, which helps pertinent institutions to quickly confirm a diagnosis of anthrax and evaluate the epidemiological situation that generates important data for further responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20disease" title="animal disease">animal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=baccilus%20anthracis" title=" baccilus anthracis"> baccilus anthracis</a>, <a href="https://publications.waset.org/abstracts/search?q=edp" title=" edp"> edp</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20molecular%20diagnostics" title=" laboratory molecular diagnostics"> laboratory molecular diagnostics</a> </p> <a href="https://publications.waset.org/abstracts/155303/molecular-epidemiology-of-anthrax-in-georgia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155303.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5100</span> Performance of the New Laboratory-Based Algorithm for HIV Diagnosis in Southwestern China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanhua%20Zhao">Yanhua Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chenli%20Rao"> Chenli Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongdong%20Li"> Dongdong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuanmin%20Tao"> Chuanmin Tao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Chinese Centers for Disease Control and Prevention (CCDC) issued a new laboratory-based algorithm for HIV diagnosis on April 2016, which initially screens with a combination HIV-1/HIV-2 antigen/antibody fourth-generation immunoassay (IA) followed, when reactive, an HIV-1/HIV-2 undifferentiated antibody IA in duplicate. Reactive specimens with concordant results undergo supplemental tests with western blots, or HIV-1 nucleic acid tests (NATs) and non-reactive specimens with discordant results receive HIV-1 NATs or p24 antigen tests or 2-4 weeks follow-up tests. However, little data evaluating the application of the new algorithm have been reported to date. The study was to evaluate the performance of new laboratory-based HIV diagnostic algorithm in an inpatient population of Southwest China over the initial 6 months by compared with the old algorithm. Plasma specimens collected from inpatients from May 1, 2016, to October 31, 2016, are submitted to the laboratory for screening HIV infection performed by both the new HIV testing algorithm and the old version. The sensitivity and specificity of the algorithms and the difference of the categorized numbers of plasmas were calculated. Under the new algorithm for HIV diagnosis, 170 of the total 52 749 plasma specimens were confirmed as positively HIV-infected (0.32%). The sensitivity and specificity of the new algorithm were 100% (170/170) and 100% (52 579/52 579), respectively; while 167 HIV-1 positive specimens were identified by the old algorithm with sensitivity 98.24% (167/170) and 100% (52 579/52 579), respectively. Three acute HIV-1 infections (AHIs) and two early HIV-1 infections (EHIs) were identified by the new algorithm; the former was missed by old procedure. Compared with the old version, the new algorithm produced fewer WB-indeterminate results (2 vs. 16, p = 0.001), which led to fewer follow-up tests. Therefore, the new HIV testing algorithm is more sensitive for detecting acute HIV-1 infections with maintaining the ability to verify the established HIV-1 infections and can dramatically decrease the greater number of WB-indeterminate specimens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algorithm" title="algorithm">algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory" title=" laboratory"> laboratory</a> </p> <a href="https://publications.waset.org/abstracts/68960/performance-of-the-new-laboratory-based-algorithm-for-hiv-diagnosis-in-southwestern-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68960.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5099</span> Analyzing the Effectiveness of Different Testing Techniques in Ensuring Software Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20M.%20P.%20C.%20Bandara">R.

Four specific objectives were stated to guide the study, four research questions were investigated, four null hypothesis were tested at 0.05 level of significance. A survey design was used and science laboratory management questionnaires which solicit responses that was used in answering the research questions and testing of hypotheses. These questionnaires were distributed to the respective respondents in the sampled colleges. The respondents for the study comprised biology chemistry, physics, integrated science teacher trainers and the paraprofessionals. Data were analyzed using mean and standard deviation to answer the questions. Chi-square statistical technique was used to test the hypothesis. The findings of the study revealed that all procedures on control of laboratory activities were rarely observed. Safety procedures were occasionally practiced. On provision and procurement of laboratory equipment and materials it was observed that both academic and the paraprofessional were not fully involved. While maintenance measures were occasionally observed, furthermore science laboratory management procedures are not frequently practiced. Hence making the acquisition of science process skills by students becoming difficult. To arrest these anomalies, it is recommended that direct labor in the maintenance of laboratory equipment and other apparatus by paraprofessional is crucial. Training of academic and paraprofessional through workshops to acquire technical skills in maintenance of science laboratory equipment be instituted to increase professionalism. Periodic supervision of activities in the science laboratories should be done promptly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laboratory" title="laboratory">laboratory</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=standard" title=" standard"> standard</a>, <a href="https://publications.waset.org/abstracts/search?q=facility" title=" facility"> facility</a> </p> <a href="https://publications.waset.org/abstracts/22804/an-analysis-of-laboratory-management-practices-and-laid-down-standard-in-some-colleges-of-education-in-kano-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22804.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5097</span> A Comparative Study of Three Major Performance Testing Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulaziz%20Omar%20Alsadhan">Abdulaziz Omar Alsadhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Mudasir%20Shafi"> Mohd Mudasir Shafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Performance testing is done to prove the reliability of any software product.

The objective was to provide a decision tool for improving soil fertility. One aspect of soil test kit development was ease of use which is a time requirement for completing organic matter, available phosphorus and exchangeable potassium test in one soil sample. This testing kit required only two extractions and utilized no filtration consuming approximately 15 minutes per sample. Organic matter was principally created by oxidizing carbon KMnO₄ using the standard color chart. In addition, modified single extractant (Mehlich I) was applied to extract available phosphorus and exchangeable potassium. Molybdenum blue method and turbidimetric method using standard color chart were adapted to analyze available phosphorus and exchangeable potassium, respectively. Modified single extractant using in soil test kits were highly significant matching with analytical laboratory results (r=0.959** and 0.945** for available phosphorus and exchangeable potassium, respectively). Linear regressions were statistically calculated between modified single extractant and standard laboratory analysis (y=0.9581x-12.973 for available phosphorus and y=0.5372x+15.283 for exchangeable potassium, respectively). These equations were calibrated to formulate a fertilizer rate recommendation for specific corps. To validate quality, soil test kits were distributed to farmers and extension workers. We found that the accuracy of soil test kits were 71.0%, 63.9% and 65.5% for organic matter, available phosphorus, and exchangeable potassium, respectively. The quantitative survey was also conducted in order to assess their satisfaction with soil test kits. The survey showed that more than 85% of respondents said these testing kits were more convenient, economical and reliable than the other commercial soil test kits. Based upon the finding of this study, soil test kits can be another alternative for providing soil analysis and fertility recommendations when a soil testing laboratory is not available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=available%20phosphorus" title="available phosphorus">available phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=exchangeable%20potassium" title=" exchangeable potassium"> exchangeable potassium</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20single%20extractant" title=" modified single extractant"> modified single extractant</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title=" organic matter"> organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20test%20kits" title=" soil test kits"> soil test kits</a> </p> <a href="https://publications.waset.org/abstracts/98706/development-of-soil-test-kits-to-determine-organic-matter-available-phosphorus-and-exchangeable-potassium-in-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98706.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5095</span> On Definition of Modulus of Deformation of Ground by Laboratory Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olgha%20Giorgishvili">Olgha Giorgishvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work is mainly concerned with the determination of modulus of deformation by laboratory method.

The study was conducted through a survey questionnaire that was given to a random sample of 19 respondents (eight privately-owned and eleven government-owned hospitals), mainly CMTs, MTs, and Supervisors from UST-affiliated hospitals. The pre-analytical laboratory errors, which include misidentification errors, transcription errors, sample collection errors and sample handling and transportation errors, were considered as variables according to the IFCC WG-LEPS. Data gathered were analyzed using the Mann-Whitney U test, Percentile, Linear Regression, Percentage, and Frequency. The laboratory performance of both hospitals is High level. There is no significant difference between the laboratory performance between the two stated variables. Moreover, among the four QIs, sample handling and transportation errors contributed most to the difference between the two variables. Outcomes indicate satisfactory performance between both variables. However, in order to ensure high-quality and efficient laboratory operation, constant vigilance and improvements in pre-analytical QI are still needed. Expanding the coverage of the study, the inclusion of other phases, utilization of parametric tests are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-analytical%20phase" title="pre-analytical phase">pre-analytical phase</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20indicators" title=" quality indicators"> quality indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20performance" title=" laboratory performance"> laboratory performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-analytical%20error" title=" pre-analytical error"> pre-analytical error</a> </p> <a href="https://publications.waset.org/abstracts/137870/pre-analytical-laboratory-performance-evaluation-utilizing-quality-indicators-between-private-and-government-owned-hospitals-affiliated-to-university-of-santo-tomas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137870.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5093</span> Deployed Confidence: The Testing in Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shreya%20Asthana">Shreya Asthana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Testers know that the feature they tested on stage is working perfectly in production only after release went live. Sometimes something breaks in production and testers get to know through the end user’s bug raised. The panic mode starts when your staging test results do not reflect current production behavior. And you started doubting your testing skills when finally the user reported a bug to you. Testers can deploy their confidence on release day by testing on production. Once you start doing testing in production, you will see test result accuracy because it will be running on real time data and execution will be a little faster as compared to staging one due to elimination of bad data. Feature flagging, canary releases, and data cleanup can help to achieve this technique of testing. By this paper it will be easier to understand the steps to achieve production testing before making your feature live, and to modify IT company’s testing procedure, so testers can provide the bug free experience to the end users. This study is beneficial because too many people think that testing should be done in staging but not in production and now this is high time to pull out people from their old mindset of testing into a new testing world. At the end of the day, it all just matters if the features are working in production or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bug%20free%20production" title="bug free production">bug free production</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20testing%20mindset" title=" new testing mindset"> new testing mindset</a>, <a href="https://publications.waset.org/abstracts/search?q=testing%20strategy" title=" testing strategy"> testing strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=testing%20approach" title=" testing approach"> testing approach</a> </p> <a href="https://publications.waset.org/abstracts/176445/deployed-confidence-the-testing-in-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176445.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5092</span> A Laboratory–Designed Activity in Ecology to Demonstrate the Allelopathic Property of the Philippine Chromolaena odorata L.

(hagonoy) leaf extracts to Lycopersicum esculentum (M), commonly known as tomatoes. Ethanol extracts of C. odorata leaves were tested on seed germination and seedling growth of L. esculentum in 7-day and 14-day observation periods. Analysis of variance and Tukey’s HSD post hoc test was utilized to determine differences among treatments while Pre–test – Post–test experimental design was utilized in the determination of the effectiveness of the designed laboratory activity. Results showed that the 0.5% concentration level of ethanol leaf extracts significantly inhibited germination and seedling growth of L. esculentum in both observation periods. These results were used as the basis in the development of instructional material in ecology. The laboratory activity underwent face validation by five (5) experts in various fields of specialization, namely, Biological Sciences, Chemistry and Science Education. The readability of the designed laboratory activity was determined using a Cloze Test. Pilot testing was conducted and showed that the laboratory activity developed is found to be a very effective tool in supplementing learning about allelopathy in ecology class.

Despite a significant portion of the software development lifecycle and resources are dedicated to testing, software failures are a relatively frequent occurrence. Nevertheless, the evaluation of testing effectiveness remains at the forefront of ensuring high-quality software and software metrics play a critical role in providing valuable insights into quantifiable objectives to assess the level of assurance and confidence in the system. As the selection of appropriate metrics can be an arduous process, the goal of this paper is to shed light on the significance of software metrics by examining a range of testing techniques and metrics as well as identifying key areas for improvement. Additionally, through this investigation, readers will gain a deeper understanding of how metrics can help to drive informed decision-making on delivering high-quality software and facilitate continuous improvement in testing practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title="software testing">software testing</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20metrics" title=" software metrics"> software metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=testing%20effectiveness" title=" testing effectiveness"> testing effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20box%20testing" title=" black box testing"> black box testing</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20testing" title=" random testing"> random testing</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20random%20testing" title=" adaptive random testing"> adaptive random testing</a>, <a href="https://publications.waset.org/abstracts/search?q=combinatorial%20testing" title=" combinatorial testing"> combinatorial testing</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzz%20testing" title=" fuzz testing"> fuzz testing</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalence%20partition" title=" equivalence partition"> equivalence partition</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20value%20analysis" title=" boundary value analysis"> boundary value analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20box%20testing" title=" white box testing"> white box testing</a> </p> <a href="https://publications.waset.org/abstracts/169666/determining-the-most-efficient-test-available-in-software-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169666.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5090</span> Investigating the Abolishment of Virginity Testing in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nqobizwe%20Mvelo%20Ngema">Nqobizwe Mvelo Ngema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper argues that the custom of virginity testing has been revived in order to combat against social ills such as unwanted pregnancies, immorality, promiscuity and the spread of HIV/AIDS. However, virginity testing is not free from challenges such as the belief that having sexual intercourse with a virgin can cure men from AIDS, virginity testing is not accurate because there is scientific evidence supporting the fact that there many ways of losing virginity other than sexual intercourse, for example, the usage of tampons and participation in physical activities may tear the hymen. South African parliament took some positive steps in combatting against harm associated with virginity testing by regulating it in the Children’s Act. It is argued, in this paper, that the abolition of virginity testing may lead to paper law and it would be premature to abolish virginity testing in South Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equality%20rights" title="equality rights">equality rights</a>, <a href="https://publications.waset.org/abstracts/search?q=virginity%20testing" title=" virginity testing"> virginity testing</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=interdisciplinary%20law%20and%20legal%20studies" title=" interdisciplinary law and legal studies "> interdisciplinary law and legal studies </a> </p> <a href="https://publications.waset.org/abstracts/25794/investigating-the-abolishment-of-virginity-testing-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">527</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5089</span> Laboratory Testing Regime for Quantifying Soil Collapsibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anne%20C.%20Okwedadi">Anne C.

This loss of volume in soil as seen in foundation failures has caused millions of dollars’ worth of damages to public facilities and infrastructure and so has an adverse effect on the society and people. Despite these consequences and the several studies that are available, more research is still required in the study of soil collapsibility. Discerning the pedogenesis (formation) of soils and investigating the combined effects of the different geological soil properties is key to elucidating and quantifying soils collapsibility. This study presents a novel laboratory testing regime that would be undertaken on soil samples where the effects of soil type, compactive variables (moisture content, density, void ratio, degree of saturation) and loading are analyzed. It is anticipated that results obtained would be useful in mapping the trend of the combined effect thus the basis for evaluating soil collapsibility or collapse potentials encountered in construction with volume loss problems attributed to collapse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collapsible%20soil" title="collapsible soil">collapsible soil</a>, <a href="https://publications.waset.org/abstracts/search?q=geomorphological%20process" title=" geomorphological process"> geomorphological process</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20collapsibility%20properties" title=" soil collapsibility properties"> soil collapsibility properties</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20test" title=" soil test"> soil test</a> </p> <a href="https://publications.waset.org/abstracts/11788/laboratory-testing-regime-for-quantifying-soil-collapsibility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11788.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">471</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5088</span> Remote Wireless Communications Lab in Real Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20Miloudi%20Djelloul">El Miloudi Djelloul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technology nowadays enables the remote access to laboratory equipment and instruments via Internet.

Developing effective risk prediction models is a cost-effective approach to predicting and preventing complications of chronic kidney disease (CKD). This study aimed to develop an accurate machine learning model that can dynamically identify individuals at risk of CKD using various kinds of diagnostic data, with or without laboratory data, at different follow-up points. Creatinine is a key component used to predict CKD. These models will enable affordable and effective screening for CKD even with incomplete patient data, such as the absence of creatinine testing. This retrospective cohort study included data on 19,429 adults provided by a private research institute and screening laboratory in Taiwan, gathered between 2001 and 2015. Univariate Cox proportional hazard regression analyses were performed to determine the variables with high prognostic values for predicting CKD. We then identified interacting variables and grouped them according to diagnostic data categories. Our models used three types of data gathered at three points in time: non-laboratory, laboratory, and metabolic indices data. Next, we used subgroups of variables within each category to train two machine learning models (Random Forest and XGBoost). Our machine learning models can dynamically discriminate individuals at risk for developing CKD. All the models performed well using all three kinds of data, with or without laboratory data. Using only non-laboratory-based data (such as age, sex, body mass index (BMI), and waist circumference), both models predict chronic kidney disease as accurately as models using laboratory and metabolic indices data. Our machine learning models have demonstrated the use of different categories of diagnostic data for CKD prediction, with or without laboratory data. The machine learning models are simple to use and flexible because they work even with incomplete data and can be applied in any clinical setting, including settings where laboratory data is difficult to obtain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20kidney%20disease" title="chronic kidney disease">chronic kidney disease</a>, <a href="https://publications.waset.org/abstracts/search?q=glomerular%20filtration%20rate" title=" glomerular filtration rate"> glomerular filtration rate</a>, <a href="https://publications.waset.org/abstracts/search?q=creatinine" title=" creatinine"> creatinine</a>, <a href="https://publications.waset.org/abstracts/search?q=novel%20metabolic%20indices" title=" novel metabolic indices"> novel metabolic indices</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20prediction" title=" risk prediction"> risk prediction</a> </p> <a href="https://publications.waset.org/abstracts/159349/a-machine-learning-model-for-dynamic-prediction-of-chronic-kidney-disease-risk-using-laboratory-data-non-laboratory-data-and-metabolic-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159349.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5086</span> Pre-Service Science Teachers' Perceptions Related to the Concept of Laboratory: A Metaphorical Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salih%20Uzun">Salih Uzun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The laboratory activities are seen an indispensable part of science, teaching, and learning.

However, limited LQMS implementation and progress toward accreditation in the AMR surveillance laboratory testing setting exist in Ethiopia. By addressing non-conformances (NCs) and working towards accreditation, microbiology laboratories can improve the quality of their services, increase staff competence, and contribute to mitigate the spread of AMR. Methods: Using standard ISO 15189 horizontal and vertical assessment checklists, certified assessors identified NCs at Hawassa and Jimma Hospital microbiology laboratories. The Ethiopian Public Health Institute AMR mentors and IDDS staff prioritized closing the NCs through the implementation of an intensified mentorship program that included ISO 15189 orientation training, resource allocation, and action plan development. Results: For the two facilities to clear their NCs, an intensified mentorship approach was adopted by providing ISO 15189 orientation training, provision of buffer reagents, controls, standards, and axillary equipment, and facilitating equipment maintenance and calibration. Method verification and competency assessment were also conducted along with the implementation of standard operating procedures and recommended corrective actions. This approach enhanced the laboratory's readiness for accreditation. After addressing their NCs, the two laboratories applied to Ethiopian Accreditation Services for ISO 15189 accreditation. Conclusions: Clearing NCs through the implementation of intensified mentorship was crucial in preparing the two laboratories for accreditation and improving quality laboratory test results. This approach can guide other microbiology laboratories’ accreditation attainment efforts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-conformance%20clearance" title="non-conformance clearance">non-conformance clearance</a>, <a href="https://publications.waset.org/abstracts/search?q=intensified%20mentorship" title=" intensified mentorship"> intensified mentorship</a>, <a href="https://publications.waset.org/abstracts/search?q=accreditation" title=" accreditation"> accreditation</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%2015189" title=" ISO 15189"> ISO 15189</a> </p> <a href="https://publications.waset.org/abstracts/179374/non-conformance-clearance-through-an-intensified-mentorship-towards-iso-15189-accreditation-the-case-of-jimma-and-hawassa-hospital-microbiology-laboratories-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5084</span> The Condition Testing of Damaged Plates Using Acoustic Features and Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyle%20Saltmarsh">Kyle Saltmarsh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acoustic testing possesses many benefits due to its non-destructive nature and practicality.

Blood collection is a simple process, but can be a potential cause of pre-analytical errors. Vacuum blood collection tubes used to collect and store the blood specimens is necessary for accurate test results. The purpose of this study was to validate Improve serum separator tube(SST) (Guanzhou Improve Medical Instruments Co., Ltd, China) for routine clinical chemistry laboratory testing. Blood specimens were collected from 100 volunteers in three different serum vacuum tubes (Greiner SST , Becton Dickinson SST , Improve SST). The specimens were evaluated for 16 routine chemistry tests using TBA-200FR NEO (Toshiba Medical Co. JAPAN). The results were statistically analyzed by paired t-test and Bland-Altman plot. For stability test, the initial results for each tube were compared with results of 72 hours preserved specimens. Their clinical availability was evaluated by biological Variation of Ricos data bank. Paired t-test analysis revealed that AST, ALT, K, Cl showed statistically same results but calcium (CA), phosphorus(PHOS), glucose(GLU), BUN, uric acid(UA), cholesterol(CHOL), total protein(TP), albumin(ALB), total bilirubin(TB), ALP, creatinine(CRE), sodium(NA) were different(P < 0.05) between Improve SST and Greiner SST. Also, CA, PHOS, TP, TB, AST, ALT, NA, K, Cl showed statistically the same results but GLU, BUN, UA, CHOL, ALB, ALP, CRE were different between Improve SST and Becton Dickinson SST. All statistically different cases were clinically acceptable by biological Variation of Ricos data bank. Improve SST tubes showed satisfactory results compared with Greiner SST and Becton Dickinson SST. We concluded that the tubes are acceptable for routine clinical chemistry laboratory testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20collection" title="blood collection">blood collection</a>, <a href="https://publications.waset.org/abstracts/search?q=Guanzhou%20Improve" title=" Guanzhou Improve"> Guanzhou Improve</a>, <a href="https://publications.waset.org/abstracts/search?q=SST" title=" SST"> SST</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20tube" title=" vacuum tube"> vacuum tube</a> </p> <a href="https://publications.waset.org/abstracts/44753/evaluation-of-the-improve-vacuum-blood-collection-tube-for-laboratory-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44753.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5082</span> The Small Strain Effects to the Shear Strength and Maximum Stiffness of Post-Cyclic Degradation of Hemic Peat Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Adnan">Z.

For this purpose, a number of strain-controlled static, cyclic and post-cyclic triaxial tests were carried out in undrained condition on hemic peat soil. The shear strength and maximum stiffness of hemic peat are evaluated immediately after post-cyclic monotonic testing. There are two soil samples taken from West Johor and East Malaysia peat soil. Based on these laboratories and field testing data, it was found that the shear strength and maximum stiffness of peat soil decreased in post-cyclic monotonic loading than its initial shear strength and stiffness. In particular, degradation in shear strength and stiffness is more sensitive for peat soil due to fragile and uniform fibre structures. Shear strength of peat soil, τ<sub>max</sub> = 12.53 kPa (Beaufort peat, BFpt) and 36.61 kPa (Parit Nipah peat, PNpt) decreased than its initial 58.46 kPa and 91.67 kPa. The maximum stiffness, G<sub>max</sub> = 0.23 and 0.25 decreased markedly with post-cyclic, G<sub>max</sub> = 0.04 and 0.09. Simple correlations between the G<sub>max</sub> and the τ<sub>max</sub> effects due to small strain, ε = 0.1, the G<sub>max</sub> values for post-cyclic are relatively low compared to its initial G<sub>max</sub>. As a consequence, the reported values and patterns of both the West Johor and East Malaysia peat soil are generally the same. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-cyclic" title="post-cyclic">post-cyclic</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20stiffness" title=" maximum stiffness"> maximum stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a> </p> <a href="https://publications.waset.org/abstracts/65062/the-small-strain-effects-to-the-shear-strength-and-maximum-stiffness-of-post-cyclic-degradation-of-hemic-peat-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65062.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5081</span> The Benefits of Security Culture for Improving Physical Protection Systems at Detection and Radiation Measurement Laboratory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ari%20S.%20Prabowo">Ari S.

Physical Protection Systems (PPS) in Detection and Radiation Measurement Laboratory needs to be improved continually by using internal resources. The nuclear security culture provides some potentials to support this research. The study starts by identifying the security function’s weaknesses and its strengths of security culture as a purpose. Secondly, the strengths of security culture are implemented in the laboratory management. Finally, a simulation was done to measure its effectiveness. Some changes were happened in laboratory personnel behaviors and procedures. All became more prudent. The results showed a good influence of nuclear security culture in laboratory security functions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laboratory" title="laboratory">laboratory</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20protection%20system" title=" physical protection system"> physical protection system</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20culture" title=" security culture"> security culture</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20function" title=" security function"> security function</a> </p> <a href="https://publications.waset.org/abstracts/102746/the-benefits-of-security-culture-for-improving-physical-protection-systems-at-detection-and-radiation-measurement-laboratory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5080</span> Mobile Application Testing Matrix and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bakhtiar%20Amen">Bakhtiar Amen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sardasht%20Mahmood"> Sardasht Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Joan%20Lu"> Joan Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adoption of smartphones and the usages of mobile applications are increasing rapidly. Consequently, within limited time-range, mobile Internet usages have managed to take over the desktop usages particularly since the first smartphone-touched application released by iPhone in 2007. This paper is proposed to provide solution and answer the most demandable questions related to mobile application automated and manual testing limitations. Moreover, Mobile application testing requires agility and physically testing. Agile testing is to detect bugs through automated tools, whereas the compatibility testing is more to ensure that the apps operates on mobile OS (Operation Systems) as well as on the different real devices. Moreover, we have managed to answer automated or manual questions through two mobile application case studies MES (Mobile Exam System) and MLM (Mobile Lab Mate) by creating test scripts for both case studies and our experiment results have been discussed and evaluated on whether to adopt test on real devices or on emulators? In addition to this, we have introduced new mobile application testing matrix for the testers and some enterprises to obtain knowledge from. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20app%20testing" title="mobile app testing">mobile app testing</a>, <a href="https://publications.waset.org/abstracts/search?q=testing%20matrix" title=" testing matrix"> testing matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=automated" title=" automated"> automated</a>, <a href="https://publications.waset.org/abstracts/search?q=manual%20testing" title=" manual testing "> manual testing </a> </p> <a href="https://publications.waset.org/abstracts/23955/mobile-application-testing-matrix-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">478</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5079</span> A New Approach for Assertions Processing during Assertion-Based Software Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20M.%20Alakeel">Ali M. Alakeel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assertion-based software testing has been shown to be a promising tool for generating test cases that reveal program faults. Because the number of assertions may be very large for industry-size programs, one of the main concerns to the applicability of assertion-based testing is the amount of search time required to explore a large number of assertions. This paper presents a new approach for assertions exploration during the process of Assertion-Based software testing. Our initial exterminations with the proposed approach show that the performance of Assertion-Based testing may be improved, therefore, making this approach more efficient when applied on programs with large number of assertions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title="software testing">software
