1. Short-term mine scheduling targeting stationary grades
Abstract In short-term mine planning, mining scheduling is generally defined by designing dig-lines, allocated on benches. The mined ore will be sent to stockpiles, homogenization piles, or a concentration plant. The process to design dig-lines is usually done manually, whereby multiple simultaneous mining fronts are time-consuming and labour-intensive. The

3. Using multiple random walk simulation in short-term grade models
Abstract Geostatistical simulation comprises a variety of techniques which can help on the decision-making process for uncertainties. They allow the uncertainty assessment of function responses (which depend on the simulated inputs) commonly through a non-linear relationship (net present value, interest tax return, geometallurgical ore recovery...). However,

4. Comportamento crÃtico de filmes Ising - S=1 em estruturas cÃbicas simples
Usamos simulaÃÃes Monte Carlo e teoria de escala de tamanho finito para estudar o comportamento magnÃtico de filmes finos, em funÃÃo da espessura LZ dos filmes. Consideramos sistemas de spin S = 1, com interaÃÃes entre primeiros vizinhos em estruturas cÃbicas simples na geometria de filmes, LÃLÃLZ, com condiÃÃes de contorno periÃdicas ao longo d

5. Um ambiente distribuido para rastreamentos de objetos em tempo real
This thesis deals with the problem of tracking objects from multiple static cameras. Each camera covers a specific area where the events take place, and the union of the images of the cameras cover the whole tracking area. The thesis presents a system that divides the tracking in two modules. The first module detects all the objects present in the tracking a

6. Uma ferramenta computacional para processamento de imagens obtidas por cineangiocardiografia e avaliação da função ventricular esquerda
Cineangiocardiography has been considered the most reliable technique to examine cardiac functions. Although subjective visual interpretation of ventriculography data is the most widely method used, many studies show a high interobsel Verand intraobserver variability. In order to perform a semiautomatic analysis of the left ventricle function, it has been de

7. Calibration of an autocorrelation-based method for determining amplitude histogram reliability and quantal size.
1. We describe a method, based on autocorrelation and Monte Carlo simulation, for determining the likelihood that peaks in synaptic amplitude frequency histograms could have been a result of finite sampling from parent distributions that were unimodal. 2. The first step was to calculate an 'autocorrelation score' for the histogram to be tested. A unimodal di

8. Associative memory Hamiltonians for structure prediction without homology: Alpha-helical proteins
Energy landscape theory is used to obtain optimized energy functions for predicting protein structure, without using homology information. At short sequence separation the energy functions are associative memory Hamiltonians constructed from a database of folding patterns in nonhomologous proteins and at large separations they have the form of simple pa

9. Properties of adenosine-triphosphate-regulated potassium channels in guinea-pig ventricular cells.
A class of K channels in cardiac muscle is reversibly blocked by intracellular adenosine 5'-triphosphate (ATP). The characteristics of this K channel were studied by recording single-channel currents in ventricular cells isolated enzymatically from guinea-pig heart. The reversal potential of single-channel currents agreed well with the K equilibrium potentia

10. Conductance properties of the Na(+)-activated K+ channel in guinea-pig ventricular cells.
1. The Na(+)-activated K+ channel current was recorded from inside-out membrane patches excised from single ventricular cells of guinea-pig hearts. 2. The single channel current-voltage relations showed inward-going rectification with an asymptotic conductance of 180-210 pS for the inward current at 150 mM [K+]o, when [K+]i was changed between 5.4 and 150 mM

11. Adrenergic transmissions in the guinea-pig mesenteric artery and their cholinergic modulations.
1. Neuromuscular transmission in the guinea-pig mesenteric artery and the effect of acetylcholine (ACh) on transmission were investigated by the micro-electrode method. 2. The membrane potential, length and time constant of the smooth muscle of the mesenteric artery were found to be -69.6 +/- 1.9 mV, 0.81 +/- 0.15 mm and 129 +/- 42 msec, respectively. 3. Per

12. Spontaneous quantal currents in a central neuron match predictions from binomial analysis of evoked responses.
Inhibitory postsynaptic currents occurring spontaneously in the teleost Mauthner cell were analyzed with the single-electrode voltage-clamp technique. They were collected during depolarizing steps and were outward-going; this procedure allowed them to be isolated from possible excitatory currents flowing in the opposite direction. Their amplitude histograms
