The Cost

Software testing is a very crucial, effective and efficient stage in Software Development Life Cycle. As Customers satisfaction and reliability is very essential, this can be achieved by testing phase. The cost can be reduced when testing time is decreased. Hence, combinatorial method is a very effective and well-proved method where high quality of software can be delivered with less time. It is very exhaustive and hard phase to check all the combination of the input parameters given to authenticate the proper functioning of software system before delivering. Many issues are triggered in an application by the interaction of one or more parameters. Hence it is significant to check all the combination of N or fewer parameters in all N-way combinational input. This way of combinatorial testing will yield high guarantee software system such that all the faults have been discovered effectively. Manual Testing of this type of combinatorial inputs is impossible so there are few standard algorithms such as IPOG-C later defined as IPOGD, etc. In this paper, we are presenting the performance of Combinatorial Testing Technique called IPOG-Modified Design method with the IPOGD Technique and Manual way of test case generation. The results are evaluated for N-way combinational inputs of seven parameters. Evaluation of results shows that the IPOG-Modified Design Technique yields better performance than the IPOGD Technique and manual technique for the same input data set. Over all the IPOGD and IPOGMD Combinatorial testing methods can reduce cost, improves efficiency in software testing for numerous applications.

Software Reliability Growth

A software developer has to test to verify the implemented functions based on its requirement specification. We use many various test-cases for testing. Then, there is a set of the modules and functions in the software system to be influenced by the executed test-cases. The set is called a testing-domain and it spreads with the progress of testing. The growth rate of testing-domain in the software system is closely related to the quality and quantity of the executed test-cases by testing. Further, the quality of test-cases is related to the testing-skill of test-case designers. In this paper, we discuss testing-domain dependent software reliability growth models. The models are formulated by a nonhomogeneous Poisson process. Further, we propose three kinds of testing-domain, i.e., the basic testing-domain, the testing-domain with skill-factor, and the testing-domain with imperfect debugging. Finally, these models are applied to fault data observed in actual development projects, the software reliability analysis results are shown, and the comparisons of goodness-of-fit with the conventional software reliability growth models are performed.

Quantitative Radioautography

IntroductionSeveral methods of mounting emulsion for radioautography at the electron microscopic level have been reported. From the viewpoint of quantitative radioautography, however, there are many critical problems in the procedure to produce radioautographs. For example, it is necessary to apply and develop emulsions in several experimental groups under an identical condition. Moreover, it is necessary to treat a lot of grids at the same time in the dark room for statistical analysis. Since the complicated process and technical difficulties in these procedures are inadequate to conduct a quantitative analysis of many radioautographs at once, many factors may bring about unexpected results. In order to improve these complicated procedures, a simplified dropping method for mass production of radioautographs under an identical condition was previously reported. However, this procedure was not completely satisfactory from the viewpoint of emulsion homogeneity. This paper reports another improved procedure employing wire loops.

Fractured Surface

To bring out details in the fractured surface of a frozen sample in the freeze fracture/freeze-etch technique,the sample or part of it is warmed to enhance water sublimation.One way to do this is to raise the temperature of the entire sample to about -100°C to -90°C. In this case sublimation rates can be calculated by using plots such as Fig.1 (Talmon and Thomas),or by simplified formulae such as that given by Menold and Liittge. To achieve higher rates of sublimation without heating the entire sample a radiative heater can be used (Echlin et al.). In the present paper a simplified method for the calculation of the rates of sublimation under a constant heat flux F [W/m2] at the surface of the sample from a heater placed directly above the sample is described.

Simplified Method

SummaryAim: For the therapeutic application of radiopharmaceuticals the activity is determined on an individual basis. Here we investigated the accuracy for a simplified assessment of the residence times for a 188Re-labelled anti-CD66 monoclonal antibody. Patients, methods: For 49 patients with high risk leukaemia (24 men, 25 women, age: 44 ± 12 years) the residence times were determined for the injected 188Re-labelled anti-CD66 antibodies (1.3 ± 0.4 GBq, 5–7 GBq/mg protein, >95% 188Re bound to the antibody) based on 5 measurements (1.5, 3, 20, 26, and 44 h p.i.) using planar conjugate view gamma camera images (complete method). In a simplified method the residence times were calculated based on a single measurement 3 h p.i. Results: The residence times for kidneys, liver, red bone marrow, spleen and remainder of body for the complete method were 0.4 ± 0.2 h, 1.9 ± 0.8 h, 7.8 ± 2.1 h, 0.6 ± 0.3 h and 8.6 ± 2.1 h, respectively. For all organs a linear correlation exists between the residence times of the complete method and the simplified method with the slopes (correlation coefficients R > 0.89) of 0.89, 0.99, 1.23, 1.13 and 1.09 for kidneys, liver, red bone marrow, spleen and remainder of body, respectively. Conclusion: The proposed approach allows reliable prediction of biokinetics of 188Re-labelled anti-CD66 monoclonal antibody biodistribution with a single study. Efficient pretherapeutic estimation of organ absorbed dose may be possible, provided that a more stable anti-CD66 antibody preparation is available.
