RRAM-based Low-Power Neuromorphic Computing Engine for Space Applications
No full textWith recent breakthroughs in AI and deep learning, applying these techniques to on-board computers for space applications has grown in interest to engineers on space applications. The space field brings its own challenges, such as reliability and power restrictions. The proposed solution in this work concerns a neuromorphic accelerator for a spiking neural network (SNN) designed using memristive devices (RRAM), dubbed the Newtype Learning Computer. To this end, this work presents the following contributions: A design for a behavioral VHDL implementation of a target SNN boasting software-level accuracy, specifically built for edge AI in space. We also present a characterized ASIC design of one layer of this SNN, analyzed using RTL design tools. An analysis of this same layer designed using Memristive Crossbar Arrays is also provided, and we present a comparison of both. When simulating 4096 neurons, the RRAM-based design shows 174x smaller area, power dissipation reduction of 27x energy reduction by 4 orders of magnitude and over 80x faster by latency compared to the CMOS-based design. This thesis presents a confident first step towards the use of RRAM-based neuromorphic accelerators for spiking neural networks in space-based applications.https://github.com/HeatPhoenix/NLC4Space Github repository for the project's files.Computer EngineeringElectrical Engineering | Embedded System
Creating a link between CAMHS and children's centres in a deprived area: A case of setting up a Work Discussion Group
No full textThis thesis explores the process of setting up a Child Psychotherapy-led outreach
service in Children’s Centres (CC) in a deprived urban setting. Our team decided that
setting up Work Discussion Groups (WDGs) for CC staff would be the best starting
point towards engaging and sensitising frontline workers to early signs of mental
health problems. This research focuses primarily on exploring both CC staff and
Child Psychotherapists’ (CPs’) experience of participating in this initiative. Semistructured interviews were conducted and then analysed using Interpretative
Phenomenological Analysis (IPA), coupled with a psychoanalytic understanding, to
shed light into the lived experience of the participants in this project. The author
draws attention to CC being containers for significant child and parental anxieties.
The CC’s increasing safeguarding role is a concerning finding of this study as it is
particularly stressful for CC staff and has implications for their practice. The study -
in line with existing literature- highlights the importance of time and a consistent
‘therapeutic presence’ in CC. Understanding the culture of the institution and taking
into account the impact of deprivation and financial insecurity are essential aspects
to be considered when designing and implementing an intervention in a deprived
community. Powerful dynamics that give rise to unconscious attacks on the outreach
worker, splitting between good and bad services, paranoid anxieties and lack of trust
are likely to occur. CC staff struggle with managing safeguarding concerns while
they tend to focus more on parents’ difficulties and developmental issues and less on
children’s emotional wellbeing and attachment to their carers. The author suggests
that CC staff could benefit from working closely with CPs and from participating in
WDGs on a regular and voluntary basis, so that they can be better equipped to think
about children’s emotional states
Roe v. Workman\u27s Compensation Appeals Board: Something Fishy in California Workers\u27 Compensation Law
No full textIn California an injured employee receives workers compensation from his employer and can also bring an action for damages against a third party tortfeasor. The Labor Code provides the employer with subrogation rights in order to avoid double recovery by the employee. In Roe v. WCAB, the California Supreme Court held that concurrent employer negligence will bar his credit rights and that the WCAB has jurisdiction to determine the issue of employer negligence. This note traces pre-Roe appellate decisions and then analyzes and criticizes the Roe opinion. Finally, the author proposes an alternative solution utilizing certain comparative negligence principles announced in Li v. Yellow Cab Co

Lehren der Weisheit und Tugend in auserlesenen Fabeln, Erzählungen und Liedern: Ein Buch für die Jugend
No full textSomeone must have found some very useful material in this book, since it went through ten editions! It is organized into three major sections. The first has five subsections: Activity and Industriousness; Moderation and Self-Control; Orderliness; Carefulness; and Wisdom and Innocence. The second major section has seven subsections: Love and Obedience; Brotherly Love; Charity; Justice; Honesty; Envy; and Gentleness. The third major section deals with the love and greatness of God. Some 212 texts are subsumed under these headings. I have sampled some texts. They seem surprisingly simple. A smart young mouse recognizes a trap but wants to smell the bacon. She just touches the bacon and is trapped (Kazner). Play with danger and you may get hurt (39)! A child enjoys the house of cards he built, but it falls down. What he builds next is better. Patience and courage can do great things (Gellert, 83). A good version of Hercules and the Carter comes, apparently, from Zacharia: Prayer helps, but not alone; work, and then prayer will be effective! (104). A young mouse debates -- and then makes the wrong choice -- as her mother warns and as the cat beckons (124-5). Hagedorn does a good verse presentation of The Stag and the Vine: I die because I wounded the one who gave me safety (144-45). Similarly, Gellert's The Blind and the Lame makes its point nicely (175). Lohn der Luege (193) is a good presentation of BW. This book is in surprisingly good condition for its age.This is a hardbound book (hard cover)Language note: GermanZehnte verbesserte und vermehrte AusgabeHerausgegeben von Friedrich Ludwig Wagne
The Renovationist Schism in the Don Region and the Activities of «Archbishop» Melchizedek (Nikolayev)
No full textThe article deals with the history of the renovationist schism in the Diocese of Don and Novocherkassk and with the role played in that process by “Archbishop” Melchizedek (also known as Nikolayev, Nikolev, or Nikolin). Based on a wide range of archive sources and materials of the 1920s periodicals, the author shows that the renovationist schism in the Don area was initiated by “Archbishop” Melchizedek supported by the State Political Directorate of Don Oblast. On 18 June 1922, supported by that governmental body, there was established an eparchial renovationist committee in Novocherkassk, which was the reason why Archbishop Mitrofan (Simashkevich) refused to be the head of the Diocese any longer. The renovationism localized in Novocherkassk started to spread all over the Diocese only after the arrest of the opposition Novocerkassk clergy. The parish priests who obeyed submissively to the authority of “Archbishop” Melchizedek were misinformed and so believed that he was the legitimate successor of Metropolitan Mitrofan who had “retired”. Regardless of the fast dissemination of renovationism, there were no radical reforms in the Don area as both the priests and the church people of the Diocese of Don and Novocherkassk were quite conservative. After Patriarch Tikhon had been released from prison on 26 June 1923, there started spontaneous anti-renovationist movement, both among the priests and the active laity who were not numerous though. The decisive organizational stage for the movement was the episcopal cheirotonia of Archpriest Zacharia Lobov. The coming of an active bishop to the church helm became the reason both for Metropolitan Mitrofan’s return to the church administration and eparchial parishes. And the big number of the Don parishes leaving the renovationist church administration were the reason for the arrests of Bishop Zacharia and his most active followers
Tierfabeln
No full textThe final page shows that this book was published under license of the American Military Government. It also lists the thirty-one fables and their creators. Hey has four, and Gellert and Zacharia have two each. The author creates six himself, following each time on texts of others, like Aesop or Lessing. Each left-hand page has a text, and each right-hand page the corresponding full-page black-and-white drawing. I like Heinrich Seidel's Der Zeisig (14), Matthias Claudius' Der Esel (16), Christian Fürchtegott Gellert's Die Junge Ente (26), and Gottfried Lichtwer's Der Affe und die Uhr (40). The book is 7½ x 10 and has a grouping of various animals in white-on-black on its front cover. It is canvas-bound.This is a hardbound book (hard cover)Language note: GermanOne of 10,000Ausgewählt von Hans-Wilfried von Stockhause
"A Symbol of the New African": Drum magazine, popular culture and the formation of black urban subjectivity in 1950s South Africa.
No full textPhDThis thesis examines the emergence of black urban subjectivity in South Africa
during the 1950s, focussing on the ways in which popular American genres were
utilised in the construction of black urban identities that served as a means of
resistance to apartheid. At the centre of this process was Drum magazine:
founded in South Africa in 1951 , it became the largest selling magazine on the
African continent in 1956. Drum's success was due to the way in which it
enabled the relocation of black identity from the "traditional" towards the
"modern'. The 1940s gave rise to widespread migration of black South Africans
from rural to urban areas and this newly urbanised community was seeking
models of black urban identity. Yet the Nationalist government was attempting
to curtail the emergence of a black urban proletariat, which posed a threat to
white political supremacy. Through apartheid legislation black identity was
constructed as essentially tribal and rural. As a means of resisting this, urbanised
black South Africans turned to, and appropriated, readily available forms of
American culture. Drum published Americanised images and stories: gangsters,
black detectives, black comic heroes, and pulp romances. This popular material
appeared alongside some of the finest investigative journalism ever published.
While Drum magazine is widely acknowledged as having provided a platform
for the emergence of black South African writing in English, its popular content
has been dismissed by critics as apolitical escapism, imitation and capitulation to
American culture. This thesis challenges the dismissal of the popular that has
dominated analyses of Drum since the 1960s, arguing that such a position denies
the agency of local writers and audiences. My analysis reveals that American
forms were adopted in critically discerning ways and chosen for their ability to
convey local meaning and create positions from which to resist aparthei
Culture's influence: towards understanding stakeholder interactions in rural water, sanitation and hygiene promotion projects
No full textVariations frequently occur between the intended and actual outcomes of rural water,
sanitation and hygiene promotion projects, even projects that exhibit best practice. As a result, the intended impact of poverty reduction through sustained health improvements is diminished. This thesis establishes that inadequate consideration of culture in interactions between and within project stakeholders is a major reason for these unintended project outcomes.
Aspects of individual and group behaviour that are influenced by culture are examined,
and an initial conceptual framework of established cultural dimensions developed. This framework is then applied to a broad variety of stakeholder groups: seven end user
groups and two implementing agencies in Ethiopia and Uganda; national Governments
and international donor organisations.
As a result, two new cultural dimensions are proposed. Firstly, concern for public selfimage, defined as ‘the degree to which an individual expresses interest in how others perceive him/herself, and the manner in which the individual seeks to influence that perception’. Secondly, spirituality, defined as ‘the nature and degree of people’s beliefs and practices concerning the existence, nature, and worship of, and connectedness to God, a god, gods, or a greater spiritual whole, and involvement of the divine or greater spirit in the universe and human life’. Aspects of these dimensions that need to be measured are identified.
Hierarchies of cultural dimensions are identified where a certain combination of
individual or group orientations causes the suppression or even reversal of behaviour in
a dimension. Modifications to established cultural dimensions are recommended,
especially long-term orientation which the author proposes renaming to ‘resistance to
change’.
A multidisciplinary approach that reflects the complexities of group behaviour and
converges research findings is recommended, including utilising software that simulates
complex systems.
Recommendations are made for development practitioners, especially to enhance
participation, promote femininity and achieve lasting change through training
DETEXA: declarative extensible text exploration and analysis through SQL
No full textMetadata enrichment through text mining techniques is becoming one of the most significant tasks in digital libraries. Due to the exponential increase of open access publications, several new challenges have emerged. Raw data are usually big, unstructured, and come from heterogeneous data sources. In this paper, we introduce a text analysis framework implemented in extended SQL that exploits the scalability characteristics of modern database management systems. The purpose of this framework is to provide the opportunity to build performant end-to-end text mining pipelines which include data harvesting, cleaning, processing, and text analysis at once. SQL is selected due to its declarative nature which offers fast experimentation and the ability to build APIs so that domain experts can edit text mining workflows via easy-to-use graphical interfaces. Our experimental analysis demonstrates that the proposed framework is very effective and achieves significant speedup, up to three times faster, in common use cases compared to other popular approaches. © 2023, The Author(s)
