Tydi-lang: a language for typed streaming hardware: A manual for future Tydi-lang compiler developers
No full textTransferring composite data structures with variable-length fields often requires designing non-trivial protocols that are not compatible between hardware designs. When each project designs its own data format and protocols the ability to collaborate between hardware developers is diminished, which is an issue especially in the open-source community. Because the high-level meaning of a protocol is often lost in translation to low-level languages when a custom protocol needs to be designed, extra documentation is required, the interpretation of which introduces new opportunities for errors. The Tydi specification (Tydi-spec) was proposed to address the above issues by codifying the composite and variable-length data structures in a type and providing a standard protocol to transfer typed data among hardware components. The Tydi intermediate representation (Tydi-IR) extends the Tydi-spec by defining typed interfaces, typed components, and connections among typed components.In this paper, we propose Tydi-lang, a high-level hardware description language (HDL) for streaming designs. The language incorporates Tydi-spec to describe typed streams and provides templates to describe abstract reusable components. We also implement an open-source compiler from Tydi-lang to Tydi-IR. We leverage a Tydi-IR to VHDL compiler, and also present a simulator blueprint to identify streaming bottlenecks. We show several Tydi-lang examples to translate high-level SQL to VHDL to demonstrate that Tydi-lang can efficiently raise the level of abstraction and reduce design effort.https://github.com/twoentartian/tydi-lang Source code for the thesis project.Computer Scienc

This year, CNDLS facilitated a book club for faculty featuring Distracted. We look forward to hearing Lang discuss his research and strategies for “cultivating attention” in this keynote address
Vanderbilt Center for Teaching: Episode 5 - James Lang on Teaching First-Year Students
No full textIncludes descriptive metadata provided by producer in MP3 file: "CFT Podcasting - Podcast Episodes - Episode 5 - James Lang on Teaching First-Year Students - In this episode, we feature an interview with James Lang, Associate Professor of English at Assumption College in Massachusetts. Dr. Lang is the author of Life on the Tenure Track: Lessons from the First Year, a memoir chronicling his first year as a faculty member, and On Course: A Week-by-Week Guide to Your First Semester of College Teaching. He also writes "On Course," a column on teaching that appears in the Chronicle of Higher Education. In the interview, Dr. Lang discusses the idea that undergraduate students can experience some kind of personal transformation during their first year of college. Is transformation a reasonable goal for first-year students? If not, what is a reasonable goal? What are some conditions that facilitate these types of goals? What are conditions that inhibit them?" Lang argues that self-awareness of core values is a more realistic goal. Classroom discussions rather than lectures promote self-examination.Peabody College of Education and Human Developmen
Matusekommetest Kirde-Eestis 19. sajandil ja 20. sajandi algul
No full textThe article deals with death-related beliefs and traditions in the 19th and early 20th century. The author has divided the tradition into four main periods. The first period deals with the person's illness, when the death is definitely approaching. Since the rituals and omens occurring during this period were believed to influence the future destiny of the dying person and the living, the rituals and omens became an inherent part of funeral tradition. The first period therefore prepared the dying person and his or her relatives for the future changes. Death as a biological transformation marks the beginning of the second period, involving washing and dressing the dead body and the night wakes. This is the period of communicating with the deceased - his or her conciliation with the living and the preparation for the afterlife and the prevention of any harmful effects related to death. The most detailed period of tradition was the third - the dead person's departure from home. Official church rituals were completed with popular wisdom to help the deceased to settle in the otherworld. The fourth period includes the funeral festivities, symbolising the dead person's joining the new environment, his or her reaching a new social status. Proper performing of all the mentioned periods was supposed to render the deceased harmless for the living. In the 20th century the old popular customs have begun to retreat. The first and the second period rituals are becoming obsolete, whereas the third and fourth period will be dominated by the official church ritual

Description. ♂ Forewing length: 29.5–31 mm. Forewing strongly elongated towards the apex. Upperside: ground color greyish brown; forewing postdiscal band with the paler outer border vestigial; forewing yellow subapical spots in cells M 1 and M 2 present; forewing with a weak and slender orange marginal line; hindwing postdiscal spots with the yellowish iris narrower and separated from each other by veins. Underside: ground color pale brown with markings similar to those of L. manzorum; reddish fasciae and bars narrow. Male genitalia. (Figs: 17, 18, 25 c) Uncus: very long and strongly bent downwards. Gnathos: base normal in width, then gradually tapering towards the end; it is bent downwards near the base, and bent upwards near the apex. Valva: apical part elongated distally as a tongue-shaped lobe; apex more or less rounded; dorsal edge weakly humped in apical half; central part of ventral edge angular. ♀ Forewing length: 33–34 mm. Similar to male. Upperside: forewing postdiscal band with well visible outer yellowish border which is vestigial in male. Underside: the same as in male. Diagnosis. L. sisii may be distinguished from L. manzorum by the combination of the following characters: a) upper surface of forewing with paler outer markings of postdiscal band vestigial, but prominent in L. manzorum; b) upper surface of hindwing with series of yellow ringed submarginal slender spots separated from each other; these spots somewhat wider and confluent in L. manzorum; c) under surface of both wings with reddish fasciae and bars much narrower than in L. manzorum (e.g. width of hindwing postdiscal fasciae in space 3: 0.9 –1.0 mm in this new species, 1.5–1.6 mm in manzorum); d) uncus longer than that in L. manzorum; e) gnathos bent downwards near the base, whereas it is bent upwards in L. manzorum; f) apical part of valva much more elongated than that in L. manzorum. Etymology. The specific name sisii is named after Mr. Si Si from Chengdu, a good friend of the first author. Distribution. China (Sichuan, Chongqing, SE Gansu, S.

Locally Adaptive Function Estimation for Binary Regression Models
No full textIn this paper we present a nonparametric Bayesian approach for fitting unsmooth or highly oscillating functions in regression models with binary responses. The approach extends previous work by Lang et al. (2002) for Gaussian responses. Nonlinear functions are modelled by first or second order random walk priors with locally varying variances or smoothing parameters. Estimation is fully Bayesian and uses latent utility representations of binary regression models for efficient block sampling from the full conditionals of nonlinear functions
