SPICE is a widely used tool for simulation of analog circuits. Accurate models of devices are crucial for obtaining realistic results from the simulation. Although SPICE provides circuit designers with built-in models for most widely used devices many devices still must be modelled with subcircuit models in order to achieve sufficient accuracy. The hardest part of creating a SPICE model for a p...

An efficient scheme for one-dimensional extensive air shower simulation and its implementation in the program CONEX are presented. Explicit Monte Carlo simulation of the high-energy part of hadronic and electromagnetic cascades in the atmosphere is combined with a numeric solution of cascade equations for smaller energy sub-showers to obtain accurate shower predictions. The developed scheme all...

Step-Frequency signal is widely used in radar systems. However it suffers from the technique challenges that are the imaging moving-targets. In this paper, a new compound modulation signal is analyzed. It combines phased code modulation during the pulse and Step-Frequency modulation between the pulses time, and it is called as phase-coded StepFrequency signal. Numeric simulation comparison expe...

Currently, all search algorithms which use discretization of numeric attributes for numeric association rule mining, work in the way that the original distribution of the numeric attributes will be lost. This issue leads to loss of information, so that the association rules which are generated through this process are not precise and accurate. Based on this fact, algorithms which can natively h...

A new steganographic method via the use of numeric data on public websites with a self-authentication capability is proposed. The proposed technique transforms a secret message into partial shares by Shamir’s (k, n)-threshold secret sharing scheme with n = k + 1. The generated k+1 partial shares then are embedded into the numeric items to be disguised as part of the website’s numeric content, y...

Planning with numeric state variables has been a challenge for many years, and was a part of the 3rd International Planning Competition (IPC-3). One of the currently most popular and successful algorithmic techniques in STRIPS planning is to guide search by a heuristic function, where the heuristic is based on relaxing the planning task by ignoring the delete lists of the available actions. We ...

The paper generalises the notion of landmarks for reasoning about planning problems involving propositional and numeric variables. Intuitively, numeric landmarks are regions in the metric space defined by the problem whose crossing is necessary for its resolution. The paper proposes a relaxationbased method for their automated extraction directly from the problem structure, and shows how to exp...

Previous work has identified a distributed, network of neural systems involved in appraising the value of rewards, such as when winning $100. We hypothesized that involvement of intraparietal sulcus (IPS) in this network is specialized for processing numeric rather than monetary value. To test our hypothesis, we manipulated numeric magnitude and units to construct a range of economic rewards (e...

In this paper presents two microsensors structures compatible with microelectronic technologies that are analyzed for application in radiometers. The first structure is formed by one resistor that is made by doping a monocrystalline silicon substrate with boron. The second is a polysilicon resistor doped with phosphorous, over a silicon dioxide (SiO2). The analysis is made by mathematical model...

The Qualitative Modelling and Interpretation (QMi) system translates noisy sensor data into a qualitative description of the underlying behaviorof a chemical plant and uses this information together with qualitative models to identify faults and operating regimes. Qualitative models of normal and faulty equipment are simulated to describe the range of possible behaviors in a chemical plant with...
