Objective: To study specificities of “1-out of-5”equilibrium code application in the process of concurrent error detection of combinational logic circuits organization. Methods: Information and coding theories, as well as technical diagnostics of discrete systems were applied. Results: It was suggested to apply a “1-out of-5”equilibrium code in organizing of combinational circuits control by means of Boolean complement method, the tester of which has a simple structure and needs five testing patterns for its full check. The calculation method of Boolean complement functions was given; the former makes it possible to provide testability of a Boolean complement block and a tester within a checking circuit. The advantages of a “1-out of-5”equilibrium code application were presented, compared to the usage of other equilibrium codes with a shorter length of a code word for organization of combinational circuits’ check. Practical importance: The application of a “1-out of-5”equilibrium code for organization of combinational circuits’ check is promising for self-checking discrete automatic and calculating machines.

Errors occurring in the control vectors are always detected. Unlike previous studies in this subject area, the authors focus on the features of error detection by modular sum codes in all codewords, and not just in information vectors. Previously unknown properties of error detection by modular sum- mation codes with their classification by types (unidirectional, symmetrical and asymmetrical errors) and multiplicities have been established. Catalogs of detailed characteristics of modular sum codes are provided. The key patterns inherent in this class of codes are described. The research results can be used in organizing built-in control circuits using the Boolean complement method, in solving other problems of technical diagnostics, where it is important to know the properties of detecting errors in code words, as well as problems of data protection and transmission

New Self-Checking Booth MultipliersThis work presents the first self-checking Booth-3 multiplier and a new self-checking Booth-2 multiplier using parity prediction. We propose a method which combines error-detection of Booth-3 (or Booth-2) decoder cells and parity prediction. Additionally, code disjointness is ensured by reusing logic for partial product generation. Parity prediction is applied to a carry-save-adder with the standard sign-bit extension. In this adder almost all cells have odd fanouts and faults are detected by the parity. Only one adder cell has an even fanout in the case of Booth-3 multiplication. Especially, for even-number Booth-2 multipliers parity prediction becomes efficient. Since that prediction slightly differs from previous work which describes CSA-folded adders, formulas to predict the parity are developed here. The proposed multipliers are compared experimentally with existing solutions. Only 102% of the area of Booth-2 without error detection is needed for the self-checking Booth-3 multiplier.

AbstractIn general, the development of character building in a formal education can be applied through buying and selling transaction activities in the school canteen. The widespread use of computer technology can also be applied in trade activities in school canteens as an effort to establish the character of Indonesia's young generation with integrity and honesty. The introductory on the use of technology through a Self-Purchasing System or also commonly known as the Self-Check-out System is a mechanism that provides an opportunity for customers to process their purchases by scanning the items they buy and making direct payments before leaving the store/store. This technology can be initiated into religious and non-religious-based elementary schools that practice the values integrity and honest character from a specific religion to general values. However, even though these values have become a daily part of learning, the use of modern technology in the practice of education cannot be denied. Thus, the combination of pedagogy on the conceptual character-building value in the classroom and the use of science and technology in trading activities in the school canteen will accelerate the formation of integrity and honest character within the pupils.Keywords: Character Building, Self-Purchasing System, Governance, Smart School Canteen Model.

The article provides examples of the use of programmable logic integrated circuits in various industries. Possible faults in FPGA blocks and their difference from faults in programmable logic arrays are described. Particular attention is paid to the failures of the LUT element. Features of the organization of technical diagnostics systems operating in the operating mode of the objects of diagnostics for combinational logic devices, implemented on the basis of programmable logic integrated circuits are described. Using the example of modular summation codes, it is shown that the known approaches to organizing such systems for devices implemented on a valve basis can be directly applied to devices of the type under consideration. Since malfunctions in the form of errors are recorded, and not the malfunctions themselves, the approaches to the organization of diagnostic systems are universal. It also provides a comparative characteristic of modular sum codes depending on the code module. A code has been proposed that will detect all faults in the example under study.

Several theories purport that people who stutter suffer a speech-auditory feedback defect. The disordered feedback creates the illusion that some kind of error has intruded into the speech flow. Stuttering then results from actions aimed to correct the suspected, but nonexistent, error. These auditory feedback defect theories thus predict deviant error detection performance in people who stutter during speech production. To test this prediction, subjects who stuttered and those who did not had to detect self-produced (phonemic) speech errors while speaking with normal auditory feedback and with the auditory feedback masked by white noise. The two groups did not differ significantly in error detection accuracy and speed, nor in false alarm scores. This opposes auditory feedback defect theories and suggests that the self-monitoring processes of people who stutter function normally. In a condition in which errors had to be detected in other-produced speech, i.e., while listening to a tape recording, subjects who stuttered did detect fewer errors. Whether this might signal some general phonological problem is discussed.
