This paper describes a new non-optimizing compiler for the ECMA-55 Minimal BASIC language that generates x86-64 assembler code for use on the x86-64 Linux® [1] 3.x platform. The compiler was implemented in C99 and the generated assembly language is in the AT&T style and is for the GNU assembler. The generated code is stand-alone and does not require any shared libraries to run, since it makes s...

We formulate and prove a formula to compute the expected value of the minimal random basis of an arbitrary finite matroid whose elements are assigned weights which are independent and uniformly distributed on the interval [0, 1]. This method yields an exact formula in terms of the Tutte polynomial. We give a simple formula to find the minimal random basis of the projective geometry PG (r − 1, q).

A model of an incremental shaft encoder is developed to facilitate sensor characterization. The model is obtained through derivation of a new mathematical formula for the spectral characteristics of the error which accrues when a sampled, nominally constant-rate signal is uniformly quantized, having been subject to both differential and integral nonlinearities. The spectrum of the error in the ...

This work considers the problem of universal coding of binary sequences, where the universal encoder has limited memory. Universal coding refers to a situation where a single, universal, encoder can achieve the optimal performance for a large class of models or data sequences, without knowing the model in advance, and without tuning the encoder to the data. In the previous work on universal cod...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

The thermometer code-to-binary code encoder has become the bottleneck of the ultra-high speed flash ADCs. In this paper, the authors presented the fat tree thermometer codeto-binary code encoder that is highly suitable for the ultrahigh speed flash ADCs. The simulation and the implementation results show that the fat tree encoder outperforms the commonly used ROM encoder in terms of speed and p...

Motion Estimation (ME) can consume 70% (1 reference frame) to 90% (5 reference frames) of the total encoding time of the JVT codec. In this contribution we introduce a highly efficient predictive fast motion estimation algorithm that can considerably reduce the complexity of the JVT encoder (5 times on the average) with minimal loss in coding efficiency. Our algorithm mainly employs very robust...

An eecient algorithm is developed for determining the greatest common left divisor (GCLD) of two polynomial matrices. Knowing this divisor allows for several immediate applications: In coding theory, a noncatastrophic convolutional encoder can be derived from an arbitrary one. In systems theory, irreducible matrix fraction descriptions of transfer function matrices can be found. In linear algeb...

In this paper, we consider the problem of scheduling on two-machine permutation flowshop with minimal time lags between consecutive operations of each job. The aim is to find a feasible schedule that minimizes the total tardiness. This problem is known to be NP-hard in the strong sense. We propose two mixed-integer linear programming (MILP) models and two types of valid inequalities which aim t...

This paper proposes a MAC centric cross-layer approach for H.264 video streaming over HSDPA wireless links. Our solution is based on minimal interactions between the RLC (Radio Link Control layer) and the application layer (i.e. H.264 encoder) in order to give video packets different importance values according to the semantic of their contents. The performance of our proposed solution is evalu...
