We prove a refinement of Vogel’s statement that the Vassiliev invariants of knots coming from semisimple Lie algebras do not generate all Vassiliev invariants. This refinement takes into account the second grading on the Vassiliev invariants induced by cabling of knots. As an application we get an amelioration of the actually known lower bounds for the dimensions of the space of Vassiliev invar...

The paper presents an approach to joint tracking and classification based on belief functions as understood in the transferable belief model (TBM). The TBM model is identical to the classical model except all probability functions are replaced by belief functions, which are more flexible for representing uncertainty. It is felt that the tracking phase is well handled by the classical Kalman fil...

Centuries of speculation about the causes of human stress on the environment is now being disciplined with empirical evidence, including analyses of differences in greenhouse-gas emissions across contemporary nation states. The cumulative results can provide useful guidance for both climate projections and for policy design. Growing human population and affluence clearly contribute to enhanced ...

This paper analyses security mechanism and authentication, key agreement protocol of 3G system amply, puts forward a amelioration scheme. This scheme assures security communications without credible VLR. This paper analyses ameliorative protocol and resolves the security communications problem between MS and HLR.

Large hydraulic structures are of major importance to sustained life-support systems and have an impact on the environment. Dams, reservoirs and open canals are such structures, the impact of which has been duly appreciated and addressed in environmental impact assessments and side-effects amelioration programs. Less obvious, but of vital importance, is the impact of urban drainage systems on h...

Historically, the gold standard for the treatment of congenital malformations has been planned delivery at tertiary care center with attempted post-natal repair or amelioration of the lesion. Over the last few decades however, rapid advances in imaging and instrumentation technology combined with superior knowledge of fetal pathophysiology has led to the development of novel intrauterine interv...
