Design and analysis of self clocked flip-flop based shift registers using 90 nm CMOS technology

This paper enumerates the efficient design and analysis of 4 bit shift registers using self clocked D flip-flop as a storage element. Self clocked flip-flop utilize internal clock generation mechanism, due to this it doesn’t require external clock synchronization. It is designed by utilizing relatively less number of transistors than conventional designs, which results in drastic improvement of power performance, package density and speed. Here self triggered D flip-flop is used in order to design Serial In Serial Out(SISO), Serial In Parallel Out(SIPO), Parallel In Serial Out(PISO) and Parallel In Parallel Out(PIPO) shift registers. The shift registers presented here requires comparatively less die area, reduced power consumption and high speed than conventional shift registers. Design and simulation of shift registers have been carried out using Microwind design and simulation tool using 90nm CMOS process.
Listening with your eyes: Multimodal approaches to art appreciation in primary school

espanolLas bellas artes son el escenario ideal para desarrollar un enfoque educativo multimodal. Los museos de arte, cada vez mas conscientes de su papel social, organizan actividades de difusion para dar a conocer el arte a un publico amplio. Sin embargo, hasta ahora los expertos de analisis del discurso multimodal han prestado poca atencion a los materiales didacticos ofrecidos para difundir el conocimiento del arte. Se parte del trabajo de Swales (2016) sobre el genero de la exposicion de la obra artistica (Single Image Account), que se centra en los textos sobre obras maestras pensados para el publico general. Sus criterios se aplican a los textos para fines educativos publicados en la pagina web de la National Gallery de Londres. Las explicaciones se combinan con propuestas didacticas para fomentar el aprendizaje mediante actividades creativas. Se ofrece un guia para la redaccion de SIAs para fines educativos en otros contextos. catalaLes belles arts son l’escenari ideal per desenvolupar un enfocament educatiu multimodal.

EnglishFine arts offer opportunities for multimodal approaches in education. Museums and galleries are now aware of their social role, and provide outreach activities designed to bring an understanding of art to a wider public. Their websites offer educational material for school children, showing how artistic knowledge and sensitivity can be cultivated with young age groups. However, little attention has been paid to such didactic material by discourse analysts interested in multimodality. This paper builds on Swales’s (2016) article on the genre of the single image account (SIA), which centres on texts about famous paintings written by experts for a general readership.

Producer-oriented versus consumer-oriented prefetching: a comparison and analysis of parallel application programs

Due to large remote-memory latencies, reducing the impact of cache misses is critical for large scale shared-memory multiprocessors. This thesis quantitatively compares two classes of software-controlled prefetch schemes for reducing the impact: consumer-oriented and producer-oriented schemes. Examining the behavior of these schemes leads us to characterize the communication behavior of parallel application programs. Consumer-oriented prefetch has been shown to be effective for hiding large memory latencies. Producer-oriented prefetch (called deliver), on the other hand, has not been extensively studied. Our implementation of deliver uses a hardware mechanism that tracks the set of potential consumers based on past sharing patterns. Qualitatively, deliver has an advantage since the producer sends the datum as soon as, but not before, it is ready for use. In contrast, prefetch may fetch the datum too early so that it is invalidated before use, or may fetch it too late so that the datum is not yet available when it is needed by the consumer. Our simulation results indeed show that the qualitative advantage of deliver can yield a slight performance advantage when the cache size and the memory latency are very large. Overall, however, deliver turns out to be less effective than prefetch for two reasons. First, prefetch benefits from a "filtering effect," and thus generates less traffic than deliver. Second, deliver suffers more from cache interference than prefetch. The sharing and temporal characteristics of a set of parallel applications are shown to account for the different behavior of the two prefetch schemes. This analysis shows the inherent difficulties in predicting future communication behavior of parallel applications from recent history of the application behavior. This suggests that cache accesses involved with coherency in general are much less predictable based on past behavior than other types of cache behavior.
The changing landscape of system-on-a-chip design

The 1940s are remembered in electronic history for the invention of the transistor, and the 1950s for the invention of the integrated circuit. As the millennium comes to a close, another major development in the world of electronic design has come to the forefront: the ability to integrate an entire "system" onto a single computer chip. System-on-a-chip (SOC) designs have been in existence for only a few years; however, in that span of time, the definition of the "system" designed and manufactured on a chip has significantly changed and expanded as did the technology, skills, tools and methodologies required to produce it. This paper examines the changing characteristics of SOC design, from the mid 1990s when there was a limited number of processor-based in-house designs, to the present-day definition which includes multiple processors, peripherals, communication subsystems, bus hierarchies, analog components, and radio frequency (RF). The increasing levels of SOC integration are illustrated by a family of set-top box designs.
Parallel, Serial and Hybrid Machine Tools and Robotics Structures: Comparative Study on Optimum Kinematic Designs

After their inception in the past two decades as possible alternatives to conventional Computer Numerical Controlled (CNC) machine tools structures that dominantly adapt serial structures, Parallel Kinematic Machines (PKM) were anticipated to form a basis for a new generation of future machining centers. However this hope quickly faded out as most problems associated with this type of structures still persist and could not be completely solved satisfactorily. This especially becomes more apparent in machining applications where accuracy, rigidity, dexterity and large workspace are important requirements. Although the PKMs possess superior mechanical characteristics to serial structures, particularly in terms of high rigidity, accuracy and dynamic response, however the PKMs have their own drawbacks including singularity problems, inconsistent dexterity, irregular workspace, and limited range of motion, particularly rotational motion. To alleviate the PKMs’ limitations, considerable research efforts were directed to solve these problems. Optimum design methods are among the various methods that are attempted to improve the dexterity as well as to maximize the workspace (Stoughton and Arai, 1993, Huang et al., 2000). Various methods to evaluate the workspace were suggested (Gosselin, 1990; Luh et al., 1996; Conti et al., 1998; Tsai et al., 2006). Workspace optimization is also addressed (Wang and Hsieh, 1998). A new shift in tackling the aforementioned problems came when researchers start to look at hybrid structures, consisting of parallel and serial linkages as a compromise to exploit the advantageous characteristics of the serial and parallel structures. This shift creates new research and development needs and founded new ideas. Among the early hybrid kinematic designs, the Tricept was considered as the first commercially successful hybrid machine tools. This hybrid machine which was developed by Neos Robotics, has a three-degrees-of-freedom parallel kinematic structure and a
A Comparison Of The Optical Projection Lithography Simulators In Sample And Prolith

SAMPLE and PROLITH are two computer programs widely available for simulating the optical projection photolithography process. Both programs use a combination of physical and empirical models to determine the profile in a developed resist given various imaging, exposure, and development data. Although both programs perform basically the same functions, they rely on different models and numerical algorithms for the calculation of aerial and latent images, and differ in the method adopted for propagating the development front. A notable difference to the user is that the programs also use different development-rate models. This paper documents algorithmic details not available in the open literature on these programs, and presents simulation results of representative lithography systems to illustrate differences and similarities in the developed photoresist profiles and in relevant intermediate steps. Numerical comparison demonstrates that aerial images calculated by SAMPLE and PROLITH are in generally good agreement. It is found that resist cross-sectional profiles produced by the programs at high numerical resolution provide the same qualitative lithography information for representative systems; however, a significant disagreement is found in the output of the post-exposure bake algorithms since SAMPLE predicts much lower standing-wave amplitude attenuation effects. It is argued that the dissimilar development-rate models used by each simulator do not contribute significantly to differences observed in the cross-sectional profile output. A noteworthy difference is that PROLITH is capable of predicting the asymmetric behavior observed in experimental data relating critical dimensions to defocus, whereas SAMPLE predicts completely symmetric behavior. The band algorithm used in SAMPLE for the calculation of linewidths is found to be an adequate method for estimating critical dimensions.

Prevalence of Clustering for Current Smoking,Current Drinking and Components of Metabolic Syndrome among Adults of Lanxi, Heilongjiang,China

A total of 2967 participants were surveyed in a poor county of Heilongjiang by a stratified randomized cluster sampling. Information on CVD risk factors was collected with standardized questionnaires and Laboratory Measurements during 2006 to 2007.Overall, 93.65%, 73.71%, 46.29%, 21.55% and 6.99% of rural residents had 1; 2; 3; 4 and 5 modifiable CVD risk factors (serum triglycerides(TG), high density lipoprotein cholesterol(HDL-C), hypertension, diabetes, current smoking, current drinking and overweight. Both hypertension prevalence and diabetes prevalence increased with age, but HDL-C prevalence decreased with age among both men and women (each P for trend, 0:05) Among men. While, TG, current drinking, current smoking and MS prevalence increased with age (each P for trend, < 0:001) among women. In a multivariate model including age and sex, the odds ratio (95% confidence interval [CI]) of having 1; 2; 3; 4, and 5 CVD risk factors versus none of the studied risk factors were 3.15(95%CI, 1.92-5.16), 3.73(95%CI, 2.27-6.13), 4.31(95%CI,2.59-7.17), 5.24(95% CI, 3.04-9.03), and 9.29(95% CI, 4.78-18.06), respectively,for Chinese adults 65 to 74 years old versus 35 to 44 years old; 1.77(95%CI, 1.28-2.45), 1.98(95%CI, 1.42-2.74), 2.39(95%CI, 1.70-3.35), 2.40(95% CI, 1.66-3.74),and 2.79(95% CI, 1.77-4.40), respectively, for men compared with women.
The Penn Haptic Texture Toolkit for Modeling, Rendering, and Evaluating Haptic Virtual Textures

The Penn Haptic Texture Toolkit (HaTT) is a collection of 100 haptic texture and friction models, the recorded data from which the models were made, images of the textures, and the code and methods necessary to render these textures using an impedance-type haptic device such as a SensAble Phantom Omni. This toolkit was developed to provide haptics researchers with a method by which to compare and validate their texture modeling and rendering methods. The included rendering code has the additional beneﬁt of allowing others, both researchers and designers, to incorporate our textures into their virtual environments, which will lead to a richer experience for the user
Incremental model-based discrimination of articulated movement from motion features

Discrimination of articulated movement is a central problem in perception. We present a model-based system designed to discriminate articulated movements and demonstrate its capabilities in distinguishing three human gaits. Recognition proceeds directly from uninterpreted visual motion features. The adaptive model of movement, the scenario, is based on discrete parameterized events separated by parameterized time intervals. Experimental results are shown for real data derived from moving light displays, demonstrating the effectiveness of the structured connectionist approach. <<ETX>>

Community Mapping: A Tool in the Fight Against Cigarette Smoking on American Indian Reservations

Community mapping is a helpful tool for health planners and educators, policy makers, providers, and nurses. Community mapping provides a systematic process for identifying capacities, barriers, identified goals, and serves as a resource for mobilizing neighborhoods to solve problems. The Tobacco Policies Among Plains Tribes Project conducted a community mapping process at 7 Sioux, Ojibwe, and Winnebago reservations. The purpose was to document cigarette sales and smoking activity to establish environmental influences and behaviors surrounding tobacco abuse. Mixed qualitative research methods were used. Structured observations were conducted, photographs were taken, and tribal authorities were contacted regarding smoking policies. Formal policies related to cigarette-smoking sanctions were scarce. The community mapping tool provided information for tribal policy makers and health planners. Developing culturally appropriate health policies and interventions for poor, underserved, and minority communities may be accomplished via community mapping techniques.
Simulation as a Clinical Remediation Strategy for Undergraduate Nursing Students

Given the imperative of success on the National Council Licensure Examination for Registered Nurses (NCLEX-RN) examination, academic proficiency rather than clinical competence remains the primary focus of nursing education. It is imperative that nursing programs have an intentional remediation plan to provide resources designed to monitor, evaluate and improve clinical competence, distinct from those necessary for academic success. Simulation is an established nursing pedagogy in the development of clinical competency, as it facilitates and grounds the application and reinforcement of abstract and theoretical concepts. and may be useful as a formative strategy when students show faltering clinical proficiency. Clinical and academic competency are both essential for successful completion of an undergraduate nursing program. When students struggle to perform academically, remediation efforts have often targeted academic rather than clinical proficiency given the imperative of NCLEX-RN examination success. Few nursing programs have clinical remediation plans designed to provide support for development and remediation of the more subjective and variable elements of clinical competence. And little is known about how clinical remediation may improve academic performance. One result is students who are succeeding academically despite being marginally prepared to effectively execute the role of professional registered nurse. However, a review of literature revealed a dearth of studies exploring simulation as a tool for clinical remediation in undergraduate nursing education. Using Kolb’s Experiential Learning theory as a framework, the purpose of this project was to evaluate the impact of simulation on clinical competency in students with identified clinical deficiencies. A pilot study was done using a quasi-experimental pre-test post-test design to evaluate the effects of an extra simulation on clinical competency in 33 undergraduate nursing students who were divided into control or intervention groups. CLINICAL REMEDIATION 5 Statistical analysis indicated that although both groups demonstrated improved clinical competence scores after participating in the course simulations, the intervention group did not evidence improvement beyond that of the control group after participating in an extra simulation. Further study is necessary to validate the use of simulation for clinical remediation to foster development of nursing graduates who are fully prepared to begin nursing practice.
