Abstract This paper uses an interesting case study to highlight high-resolution pulsed thermal-induced voltage alteration (TIVA) with solid immersion lens (SIL) as a technique to isolate a temperature-sensitive failure in mixed-signal circuitry, followed by circuit analysis and nanoprobing to confirm a drive strength issue caused by a process change.

Analogue To Digital

In this paper the authors discuss the issues related to the self-awareness of high-resolution, mixed-signal circuits and systems, based on S-? ADC, which is the most important and sensitive module and the key element for analogue to digital conversion. The basic methodology and framework for improving the self-awareness of such systems are presented. The methodology is based on efficient real-time measurements of a high-resolution, mixed-signal system using pseudo random signal source, real-time calculation of a distance between responses, the possibility to adapt measured circuit to minimize the distance, and changing the parameters of a reference system according to learning rules. The use of pseudo-random noise as a signal source leads to efficient and cost-effective measurements that run in parallel to the main signal processing. The calculation of the distance between the system and its reference are theoretically analysed and verified using Matlab model. The response of a system together with the response of high precision analogue to digital converter (ADC) is compared to the response of a bit-true model of a reference digital circuit. The differences are calculated using simple area-efficient cross-correlation algorithm. Together with adaptation strategy and tuning circuitry it forms the basis for self-awareness of mixed-signal circuits.

Election Results

Akin to the previous, 2014 event, with no data on voter ethnicity, no exit polls, and few post-election analyses, the 2018 Fiji election results remain something of a mystery despite the fact that there had been a significant swing in voting in favour of Opposition political parties. There have been several studies about the election results, but most of them have been done without much quantitative analyses. This study examines voting patterns of Fiji’s 2018 election by provinces, and rural-urban localities, as well as by candidates, and also compares the 2018 and 2014 elections by spending a substantial time classifying officially released data by polling stations and individual candidates. Some of the data are then further aggregated according to the political parties to which those candidates belonged. The current electoral system in Fiji is a version of a proportional system, but its use is rare and this study will provide an interesting case study of the Open List Proportional System. At the end of the analyses, this study considers possible reasons for the swing in favour of the Opposition.

Successful Isolation

Abstract Based on the understanding of laser based techniques’ physics theory and the topology/structure of analog circuit systems with feedback loops, the propagation of laser induced voltage/current alteration inside the analog IC is evaluated. A setup connection scheme is proposed to monitor this voltage/current alteration to achieve a better success rate in finding the fail site or defect. Finally, a case of successful isolation of a high resistance via on an analog device is presented.

The Relationship

Although claims questioning whether religious sacred books can be “translated” or not have been heard for quite some time, they have increased with the emergence of globalization and the increasing openness and flow of information due to modern technology. In the context of the relationship between hermeneutics and communication, one could argue that interpreting the Qur’an is an interesting case study for many reasons. Among them is the number of debates and discourses that have been raised both for and against its translation. Another reason, perhaps one of the largest barriers according to some religious Muslim groups, is that the Qur’an is fundamentally revealed and written in Arabic, and, therefore, its true meaning cannot be translated into another language. Certain verses, such as “It is a Qur’an in Arabic, without any crookedness (therein): in order that they may guard against evil” (28:39), have been presented to support this argument.
