Abstract:

We propose link structures for NoC that have properties for tolerating efficiently transient, intermittent, and permanent errors. This is a necessary step to be taken in order to implement reliable systems in future nanoscale technologies. The protection against transient errors is realized using Hamming coding and interleaving for error detection and retransmission as the recovery method. We introduce two approaches for tackling the intermittent and permanent errors. In the first approach, spare wires are introduced together with reconfiguration circuitry. The other approach uses time redunda

Abstract:

A total of 567 human teeth except third molars were studied to estimate age, using a combined method of multiple regression analysis of data from a scoring system, direct measurements with image analyser, and logarithmic transformation. As a result, the standard errors of estimate were 4.8–5.4 years in the working sample, and 2.9–5.4 years in the control sample respectively, by using a single tooth. By testing the formulae on forensic autopsy cases in Guang Dong and Guang Xi, (People's Republic of China), it is demonstrated that the standard error of estimate is 3.7 and 2.6 years respectively

Electronic equipment operating in harsh environments such as space is subjected to a range of threats. The most important of these is radiation that gives rise to permanent and transient errors on microelectronic components. The occurrence rate of transient errors is significantly more than permanent errors. The transient errors, or soft errors, emerge in two formats: control flow errors (CFEs) and data errors. Valuable research results have already appeared in literature at hardware and software levels for their alleviation. However, there is the basic assumption behind these works that the o

In the magnetic fields built by neodymium–iron–boron (NdFeB) permanent magnets, the corresponding relationship among the concentration of sodium chloride solution, glucose solution and their magnetic rotation angles was researched in the temperature range 20–24°C. A helium–neon (He–Ne) laser with a wavelength of 632.8 nm was used in the experiment as light source. A new device is designed for assembling and adjusting the NdFeB permanent magnets. The permanent magnets have no thermal effect compared to an energized solenoid. The corresponding relationship between the concentration and rotation

Abstract The Sate of California Workers’ Compensation Appeals Board (WCAB) in a February 3, 2009, decision in the consolidated cases of Almaraz vs SCIF et al. and Guzman vs Milpitas Unified School District (Almaraz/Guzman) concluded that the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, portion of the 2005 Permanent Disability Rating Schedule is rebuttable. The effects of this decision are significant for California and could catalyze challenges regarding use of the AMA Guides in other jurisdictions. Unavoidable consequences of this decision include increase

Abstract:

In selecting and determining contract employees such as Sales Promotion Girl (SPG) to become permanent employees in a company, it still seems inaccurate, because the assessment and calculation of the results of the test are done manually, so there is a possibility of errors in providing the final results of the selection. Therefore, a Decision Support System was designed that could determine SPG contract employees to become permanent employees who could assist the company in selecting the right employees. Decision Support Systems are part of a computer-based information system that is commonly

Abstract The predictive ability of the Central States growth and yield system TWIGS 3.0 was evaluated for Illinois forests. The data used to validate the system were collected from permanent plots that had been established throughout the state and maintained for up to 30 years. TWIGS growth predictions were analyzed through the differences between observed and predicted stand and species characteristics. TWIGS consistently overpredicted mean stand diameter and underpredicted tree survival over a 30-year growth projection. The combined result of prediction errors in diameter growth and tree sur

Abstract:

In this study, a current model predictive controller (MPC) is designed for a permanent magnet synchronous motor (PMSM) where the speed of the motor can be regulated precisely. First, the mathematical model, the specifications, and the drive topology of the PMSM are introduced, followed by an elaboration of the design of the MPC. The MPC is then used to predict the current in a discrete-time calculation. The phase current at the next sampling step can be estimated to compensate the current errors, thereby modifying the three-phase currents of the motor. Next, Simulink modeling of the MPC algori

The paper is dedicated to a self-assessment approach as a means of addressing fossilized errors in L2 speaking within the professional communication framework. The phenomenon of fossilization manifests in L2 spoken and written texts on phonological, lexical and grammatical level. Addressing the issue of fossilization has to deal with creating a perfect fluency/accuracy balance, increase of fluency in L2 classroom settings inevitably results in fossilized errors in learners as it compromises their accuracy on a permanent basis. In this respect it is interesting to look into common practices of

Or a mistake can cause serious but reversible harm, such as an overdose of insulin in a patient with diabetes, resulting in hypoglycemia, seizures, and coma. Or a mistake can result in serious and permanent damage for the patient, such as the failure to consider epiglottitis in an initial differential diagnosis, resulting in a chronic vegetative state for a seven-year-old boy.

Abstract:

In this paper, a novel direct torque control (DTC) scheme based on composite active vectors modulation (CVM) is proposed for permanent magnet synchronous motor (PMSM). The precondition of the accurate compensations of torque error and flux linkage error is that the errors can be compensated fully during the entire control period. Therefore, the compensational effects of torque error and flux linkage error in different operating conditions of the PMSM are analyzed firstly, and then, the operating conditions of the PMSM are divided into three cases according to the error compensational effects.

ABSTRACT Introduction The patient's head can be slightly rotated sagittally vertically or transversely with the head holding device. Because of such improper positions due to head rotation, an error can occur in cephalometric measurements. The purpose of this study was to identify the projection errors of lateral cephalometric radiograph due to head rotation in the vertical Z-axis toward the focal spot. Materials and methods Ten human dry skulls with permanent dentition were collected. Each dry skull was rotated from 0° to +20° at 5° intervals. A vertical axis, the Z-axis, was used as a rotati

Abstract Time series of weekly and daily solutions for coordinates of permanent GNSS stations may indicate local deformations in Earth’s crust or local seasonal changes in the atmosphere and hydrosphere. The errors of the determined changes are relatively large, frequently at the level of the signal. Satellite radar interferometry and especially Persistent Scatterer Interferometry (PSI) is a method of a very high accuracy. Its weakness is a relative nature of measurements as well as accumulation of errors which may occur in the case of PSI processing of large areas. It is thus beneficial to co
