Recent research has shown that cryptographers with glitches are vulnerable in front of Side Channel Attacks (SCA). Since then, several methods, such as Wave Dynamic Differential Logic (WDDL) and Masked Dual-Rail Pre-charge Logic (MDPL), have been presented to make circuits clean. In this paper, we propose a more accurate power model based on logic gates’ output transitions and divide it into pi...

For a simple graph G with no isolated edges and at most, one vertex, labeling ?:E(G)?{1,2,…,k} of positive integers to the is called irregular if weights vertices, defined as wt?(v)=?u?N(v)?(uv), are all different. The irregularity strength known maximal integer k, minimized over labelings, set ? such exists. In this paper, we determine exact value modular fan graphs.

This paper presents an in-depth case study in highperformance asynchronous adder design. A recent method, called “speculative completion”, is used. This method uses single-rail bundled datapaths but also allows early completion. Five new dynamic designs are presented for BrentKung and Carry-Bypass adders. Furthermore, two new architectures are introduced, which target (i) small number addition,...

This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

BACKGROUND/PURPOSE The Irregularity Index is a measure of border irregularity from pigmented skin lesion images. The measure attempts to quantify the degree of irregularity of the structural indentations and protrusions along a lesion border. A carefully designed study has shown that the parameters derived from the Irregularity Index were highly correlated with expert dermatologists' notion of ...

7 This paper proposes a three-stage game-theoretic model to study air-rail competition in intercity 8 passenger corridors. We consider duopolistic markets, in which a rail agency competes against an airline to 9 maximize their respective objectives. The objective of the rail agency can be maximizing profit or social welfare, 10 or a mix of the two. At the top stage, the rail agency first determ...

the track stiffness experienced by a train will vary along the track. sometimes the stiffness variation may be very large within a short distance. one example is when an unsupported sleeper is hanging in the rail. track stiffness is then, locally at that sleeper, very low. at insulated joints the bending stiffness of the rail has a discontinuity implying a discontinuity also of the track stiffn...

Rail inspection is an important task in railway maintenance. The speed and loads of trains have been increasing greatly in recent years, and these factors inevitably raise the risk of producing rail defects. Mainly the discrete surface defects impact the riding quality and safety of a railway system. However, it is a challenge to inspect such defects in a vision system because of illumination i...

Rail joints have a shorter service life than most other railway track components. The discontinuity between rail ends turns the rail joint into a weak spot, and consequently, into a track component demanding more frequent maintenance measures, which result in high maintenance costs. Moreover, difficulties are often found when assessing the damage condition of rail joints since damage conditions...
