. . . Welcome to ACM SIGMOD Record's series of interviews with distinguished members of the database community. The evaluation results comprise from systems without high workload demand (peakDuration = 0 h per day) to systems with only high workload demand (peakDuration = 24 h per day). As for runtime monitoring, verification and adaptation, we propose an externalized runtime module that is able to monitor and verify the correctness of the soft are components based on their internal status in model terms at component and system level. The prediction of bug types provides useful insights into the software maintenance process. . Some faults are vertical so that an earthquake at 10 miles depth is directly beneath the fault at the surface where the rupture of the ground can be observed. A general software fault classification is described in. 5.

Electrical networks, machines and equipments are often subjected to various types of faults while they are in operation. . There are several types of faults depending on the nature of the movement involved. . Our results include the following: (1) the appropriate rejuvenation schedule to maximize availability in each proposed scenario; (2) downtime reduction when comparing the system with and without rejuvenation; and (3) reliability analysis of different scenarios of workload variation considering the proper rejuvenation schedules. Our main goal is to find the proper VM migration schedule to maximize system availability and to analyze the impact of such a schedule on the system reliability. . . . runtime behaviour and performance of models of CPSs using commercial MDE tools is a challenging task. . . So Bruce, welcome! In addition, we have studied the factors that influence the prediction results, including different pairs of source and target projects, and the number of bug reports in the source project. . . Classification of faults . . Using Causality to Diagnose Configuration Bugs. Faults Categorization (generic) Recently, various research works have made an effort to categorize faults. These choices, which we call "neighbourhoods", turn out to be of major importance for the understanding of the bug behind the counterexample. These model types and so, Removed nearly 100 minor errors from the second edition of this book that was published in 2001. Keeping in mind the above requirements for reliability estimation, a stochastic differential equation-based software reliability growth model (SRGM) is developed for open-source software. Runtime verification can be performed using the information of model . However, when comparing unit testing to system level testing, especially for embedded systems, we observed that the test environment itself is often the cause of intermittence. For optimum results it is required to have nearly a no – fault operation of power transformer. . . To counteract such aging, a preventive maintenance approach has been devised that has been called software rejuvenation. In this paper, we propose a set of models for availability and reliability evaluation of a virtualized system with VMM software rejuvenation enabled by VM migration scheduling. Faults separate two adjacent blocks of rock that have moved past each other because of induced stresses. . The aim is to explicate a set of general concepts, of relevance across a wide range of situations and, therefore, helping communication and cooperation among a number of scientific and technical communities, including ones that are concentrating on particular types of system, of system failures, or of causes of system failures. Failures caused by these bugs may well be tolerated by cleaning or c, The book was published in September 2017. Sorry, preview is currently unavailable. Three main types of faults. We found that a fix for a consistently failing test typically removed a larger number of failures detected by other tests than a fix for an intermittent test. Cloud computing serves as a platform for diverse types of applications, from low-priority to critical. Design of Fault detection and Classification . as set out in the definition of Mandelbug. Following factors are more commonly considered important in classification of faults: 1. . Some of these applications require high levels of system availability and reliability. . Five root causes are discovered. ered by the software system to deviate from correct service; able by the user, a failure will be experienced. Series faults are basically open conductor faults. This enriched model is then analysed to identify neighbourhoods.A model annotated with neighbourhoods can be exploited in two ways. . . . . The aim is to explicate a set of general concepts, of relevance across a wide range of situations and, therefore, helping communication and cooperation among a number of scientific and technical communities, including ones that are concentrating on particular types of system, of system failures, or of causes of system failures. Our proposed definition is as follows: . . Furthermore, the analysis of regression bugs in TensorFlow is conducted. Any of these four types of faults (bedding, strike, dip or oblique faults, may be either normal or reverse faults. The notion of localized movement leads to two genetically different classes of faults reflecting the two basic behaviors of rocks under stress: brittle and ductile. Bohrbugs other elements of the software system apart from the appli- The term “Bohrbug”, first used in print by Gray [2], cation itself, e.g., the operating system or the hardware. III. This phenomenon is referred to as “software aging”. They form a single queue and are served by a server with general service distribution. . An essential step to ensure TensorFlow's reliability is to understand the characteristics of bugs that occurred in TensorFlow. . They may have a displacement parallel to the strike of the fault or perpendicular to it. However, the meaning attached to the latter term is not consistent throughout literature, and often the terms are used without any explicit definitions at all. The class of aging-related bugs of an application may or may not overlap with the class of those software faults that are Heisenbugs with respect to a specific observation tool or method. Proposed fault classification delbug if the fact whether it causes a failure is influenced by 2.1. [4] proposed a proactive approach of fault manage- has recently gained recognition and importance. I note that several eminent researchers, including Richard Hamming, John Meyer, Satish Tripathi, U. Narayan Bhat, Harold Stone, were the original reviewers of the book and they liked it very much. 2. . A. Faults in DC side. . A full solution manual and a set of power point slides are being prepared for instructors. These types of bugs are known as Heisenbugs, ... Software aging is the result of the accumulation of agingrelated bugs effects. Group of faults which appear emerging outward from a common central region are called _____ a) Enechelon faults . . . It has two full chapters on multi-level models including the one on fixed-point iterative models. Several workshops (as part of ISSRE) have taken place and several special issues of journals have been devoted to this topic. . On the basis of the dip angle fault has the following types. . Join ResearchGate to find the people and research you need to help your work. Cyber-Physical Systems (CPSs) are embedded computing systems in which computation interacts closely with the physical world through sensors and actuators. . . The design process of proposed fault detection and classification approach is as follows: . Therefore, defining bug's roots causes is a complicated task. . for referring to a software fault that “went away, because, the measurement or the observation affected the phenomena, ware faults whose failure behavior alters, bugs [5] reveals two important categories of how try, scheduling in such a way that the failure does not oc-, behavior via factors belonging to the system-internal, environment of the application in which the Heisenbug, the fact that the responsible faults (referred to as “aging-, ther case, the error conditions do not lead to failures right. To solve this problem, this paper proposes a cross-project bug type prediction framework based on transfer learning. Given a liveness property, it extends the model with prefix / suffix information w.r.t. . . 3. . 3 2.3 Munich . . In recent years, researchers and practitioners have reported that software systems running continuously for a long time tend to show a degraded performance, an increased occurrence rate of failures (i.e., deviations of the delivered service from the correct service) or both. An innovative safe technique called Rx is deployed which is capable of recovering programs from both deterministic and indeterministic bugs. . hanging the environment -- restart, reboot or failover to an identical software replica. From more than a half million test verdicts, we identified intermittently and consistently failing tests, and identified their root causes using multiple sources. . . TensorFlow is one of the most popular machine learning frameworks for developing machine learning algorithms. . . . . . . . Maximum norm values, maximum detail coefficient, energy of the current signals are calculated from the Wavelet Toolbox in MATLAB/Simulink. To do so, it builds a new model from the original one containing all the counterexamples, and then compares the two models to identify neighbourhoods. . . . Aging-related bugs are similar to Heisenbugs, ... Bug reports used in this paper come from four projects, i.e., Linux, MySQL, HTTPD, and AXIS. Heisenbugs and Bohrbugs: Why are they different? recording the causal dependencies of its ex- ecution. A, B and C are the nominal . It can improve the efficiency of software testing and help developers adopt corresponding strategies to fix bugs before releasing software projects. . 10. In the re- maining cases, the dependency set method identifies the correct bug as one of two equally likely bugs. . . derlying causes are so complex and obscure as to make its, tics and Econometrics, University of Erlangen-Nurember, on other occasions no failure is experienced. sampled at sampling frequency of 20 kHz. . . The solution consists of a new set of energy correction functions in the BCTRAK routine BCEGAM.F and a corresponding calibration with the proper annihilation vertex. Therefore, errors to be detected by our solutions are mainly random software and hardware errors as well as remaining software errors and unanticipated environmental errors. . . . . . A second fault appears on the surface at a distance before the first fault ends and so on. Because of the popularity and large-scale use of TensorFlow, even a single bug may lead to severe consequences and impact a large number of users. One solution to address these requirements is having the software components information in model terms at runtime (models@run.time). Why Do Computers Stop and What Can Be Done About It? Access scientific knowledge from anywhere. Chin. Bruce is well-known for his work on relational databases, which has been very influential both inside and outside of IBM, starting with his work on the System R project. A preventive maintenance is also performed if the system is empty at age T. 1 2 Energy problem 1 2.1 Standard software . 2 2.2 QMC . . There are 8 implications based on these findings are provided for developers and users. A bug classification is performed based on fault triggering conditions, followed by the frequency distribution of different types of bugs and the evolution features of varying bug types over time. . . . . However, for a software project that has insufficient labeled data, it is difficult to train the classification model for predicting bug types. . . Multi-release of the SRGM is formulated in detail taking into consideration the effect of bug classification. We found that about 1-3% of all test cases were intermittently failing. . . . Electrical F… Our solution aims at keeping only actions in counterexamples that are relevant for debugging purposes. . The other method supports the debugging of counterexamples for liveness properties violations. . Due to a gradual depletion of OS resources, software systems behave as if they are aging -- that is, failure rate increases, Study software faults that are triggered not just by the workload but by the workload and the environment in which they operate. ³ ¿Í; Ôþ; µAEº; ä ßß V 524 TJ 861 Abstract The collision breakup problem of orbital spacecraft is studied in this paper. . . Minor defects include small faults which have no influence on the purchase of the product. It has detailed explanations and solution algorithms for all the major model types used in reliability and availability analysis. This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. I have had the pleasure of working with several groups and individual researchers around the world on this topic. In this paper, we extend Gray’s classification of software To counteract the phenomenon of software aging, Huang faults based on the phenomenon of software aging which et al. . Our results show that comparisons based on dependency sets significantly outperform comparisons based on predicate success or failure, uniquely identi- fying the correct bug 86-100% of the time. . . Finally, the SHARPE software package is recommended for the unsolved problems in the textbook. . . The resulting paperback version ( that is also cheaper) should be nearly error-free. This thesis aims at advancing the current practice on generating automatically Unified Modeling Language - State Machine (UML-SM) based software components that are able to provide their internal information in model terms at runtime.

The design process of proposed fault detection and classification approach is as follows. From analysis of the case study results and related work, we identified nine factors associated with test case intermittence. Basic definitions are given first. Fault in which hanging wall has apparently moved down with respect to foot wall is _____ a) Normal fault b) Reverse fault c) Strike-slip fault d) Hinge fault . . Regarding automation, we propose a tool supported methodology to automatically generate these software components. The results manifest the better performance of the model proposed in comparison with some preexisting SRGMs reported in the literature. . Firstly, a software fault in a specific app, cation itself, e.g., the operating system or the har, rence; i.e., a fault is a Mandelbug if its activation, faults causing failures due to side-effects of other applica-, tions and faults for which the scheduling don. This is achieved by detecting in the models some specific choices between transitions leading to a correct behaviour or falling into an erroneous part of the model. Major defects are those which when exposed, are likely to affect the purchase of … . . 15 to 20 percent of faults are double line to ground and causes the … In addition, the root causes of Bohrbugs and Mandelbugs are studied. is an inexpensive Asian edition published by Wiley Singapore. Moreover, the exemplified methodology corresponding to the attainment of the optimal date for product release is well established as it is truly capable of taking into consideration, the level of tolerance of the developer pertaining to variations in both reliability and cost. . Constraint conditions required for the breakup calculation are analyzed emphatically. . Different faults as single line to ground, double line to ground, line to line, 3 lines to ground are simulated on transmission line at various system conditions. Our proposed approach de- duces the state of a buggy computer by running predi- cates that test system correctness and comparing the re- sulting execution to that generated by running the same predicates on a reference computer. Our experiments show that the results of cross-project bug type prediction have significant improvement by adopting transfer learning. “Heisenbugs”, uses the term as a synonym for elusive faults. CLASSIFICATION OF FAULTS IN GCPV SYSTEM Faults in PV system can be identified in two side of the system: DC side and AC side, the interface between this to part is DC/AC inverter that connected to grid.The classification of faults is shown in Figure 2. We have revealed 10 important findings based on our empirical results. Design of Fault detection and Classification . . When the model violates the property, the model checker returns a counterexample, which is a sequence of actions leading to a state where the property is not satisfied. . There have been several attempts to relate software faults (or bugs) responsible for aging to other classes of faults, like Bohrbugs and Heisenbugs. . . . You can download the paper by clicking the button above. Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. . Fig. CPSs are used to control context aware systems. In addition to that, the software managers and developers primarily aim at obtaining the date of product release by attaining a compromise between maximizing the reliability level and minimizing the product development cost. . . . . . MDE aims to overcome the complexity of software construction by allowing developers to work at the high-level models of software systems instead of low-level codes. . . . .

Method basis on the signal feature extractions, with the use of frequency methods, with … It causes the conductor to make contact with the earth or ground. classifying the underlying faults as Mandelbugs; therefore, all aging-related bugs are Mandelbugs. Fast Abstract, we propose definitions for a number of fault classes and clarify their relationships. We devised and used a novel metric for classifying test cases as intermittent. . At the failure, the customers in the system are lost and the arriving customers during the maintenance are also lost. . Term Fd models the unknown inputs to the sensor(s), Qf models the sensor(s) faults and Sw models the modelling errors to the sensor(s). This allows us to study software availability (in operation). . . . First, the erroneous part of the model can be visualized with a specific focus on neighbourhoods, in order to have a global view of the bug behaviour. The research can be an important reference to predict and analyze damage characteristics of orbital collision events. Leith 6 said “… it is clear that the accurate naming and classification of faults present an exceedingly complex problem which has not yet been solved.” Reid, Gill and most workers classify faults on the basis of the orientation of the displacement, the net-slip. J. In [6] inter-circuit shunt faults and cross-country faults in a double circuit system have been identified and classified using DWT and SVM. . . ªÌßåÇË, ûÄ P-7µAE³¨Ýªß¿þ .
