Region-Aware Trace Signal Selection Using Machine Learning Technique for Silicon Validation and Debug

In today’s modern design technology,post-silicon validation is an expensive and composite task.The major challenge involved in this method is that it has limited observability and controllability of internal signals.There will be an issue during execution how to address the useful set of signals and store it in the on-chip trace buffer.The existing approaches are restricted to particular debug set-up where all the components have equivalent prominence at all the time.Practically,the verification engineers will emphasis only on useful functional regions or components.Due to some constraints like clock gating,some of the regions can be ignored during execution.Likewise,some of these regions can be verified deeply and have minimum errors compared to other control regions.The proposed system focusses on random signals that identify more errors which are prone to signal selection technique with low area overhead.To enhance the observability,a machine learning technique is developed.Based on the training samples of smaller designs,a model is developed to find out the contiguous neighbours of each flip-flop.This can eliminate the obstacles of unknown signals.This system demonstrates using Opencores and ISCAS’89 benchmark circuits that result in easy and fast error detection compared to the state-of-theart of other methods.This is also verified using gate-level error models by cross-validation of each debug run.

Muse Turned ＂Femme Fatale＂ in D. G. Rossetti＇s Painting and Poetry

In many of D. G. Rossetti＇s paintings, Elizabeth Siddal appears as a model. In real life, they formed a married couple, and the relatonship was not as idealistic as it might have been, between a muse-figure and an artist. After Elizabeth＇s death, Rossetti seemed to have been preoccupied with the ＂Lilith＂ theme in his painting and poetry and somehow he could not free himself from the haunting memory of the ＂wronged wife＂, the muse. This often found manifestation in his portrayal of the ＂femme fatale＂ images. Applying psychoanalysis to art-criticism and literary appreciation, this paper is an attempt to explore the relationship between a model and an artist, which both psychologically and aesthetically, seemed to be working beyond the former＇s death. Through a detailed analysis of the ＂Lilith＂ image in D. G. Rossetti＇s art, this paper has shown the coplexities of the artist＇s agony and anxiety over the image of a muse, a homely beloved--turned into a threatening ＂femme fatale＂, now distant, unknown, frightening yet fascinating, and mystified by death.

Can the W.T.O. Change Russia?

If Vladimir Put in returns as planned to the presidency in 2012,he will once again face the challenge of modernizing the Russian economy. This is something both he and his seat-warmer, Dmitri Medvedev,have failed to achieve during three consecutive presidential terms. A

Environmental Infrasound and Its Impact on Public Health in the Kashmir Region

In earlier published studies it was shown that an anomalous degree of human physiological ailments and a psychology of sustained anger and violence exist in highly populated countries located on boundaries of colliding Tectonic Plates in three continents at Latitude 34&#176 north. The Valley of Kashmir in Northern India is also located exactly on this latitude, hence chosen for detailed experimental verification of this phenomenon. This region also suffers from chronic public health hazards. Infrasound is very low frequency acoustic wave with frequencies ranging from 0.01 Hz to 20 Hz. It emanates from earthquakes, geological Faults, colliding tectonic plates and atmospheric wind turbulence. Hearing protections like ear muffs and ear plugs offer little protection. One single earthquake can cause multiple infrasound sources in a region. It is shown how regional geomorphology in the Kashmir Valley enhances and sustains this phenomenon. Both the percentage of population with hearing disabilities;and casualties due to social violence increase or decrease in proportion to frequency of earthquakes. Infrasound is shown to be the causal linkage. Public health hazards due to environmental infrasound closely resemble public health hazards actually being suffered by the population in Kashmir as established by formal and extensive medical investigations. Hence a Field Study was carried out to locate and record infrasound emissions in ten locations near 34&#176N latitude in Kashmir Valley. An analytical technique was developed to integrate infrasound spectrum in specific locations with public health hazards. It was discovered that infrasound recorded in South Kashmir around 34&#176N latitude at the locations of highest amplitude lies in proximity of Active Faults from earthquake ruptures;and in proximity to a large field of past earthquakes that took place in 2006-2012. A comprehensive public health security system needs to be set up very urgently. Technological measures are identified and appropriate technologies suggested cordoning off and mitigating this natural environmental hazard in the Kashmir Valley.
