Thanks to Pylyshyn's work in the imagery debate, theorists are now apt to be at least a bit more cautious when they launch into descriptions of depictive representation. Even if the full force of his critique is not everywhere acknowledged, more care and vigilance is exercized when broaching talk of scanning mental images, focusing on such entities, or rotating them. The very places found in me...

Several heterogeneous positioning systems are more and more widespread among client wireless terminals, thus leveraging the market relevance of Location Based Services (LBSs). Positioning techniques are very differentiated, e.g., in terms of precision, accuracy, and battery/bandwidth consumption, and several of them are simultaneously available at clients. That motivates novel middleware soluti...

Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth’s reflectivity series. Historically vibratory seismic su...

The location of the distribution facilities and the routing of the vehicles from these facilities are interdependent in many distribution systems. Such a concept recognizes the interdependence; attempts to integrate these two decisions have been limited. Multi-objective location-routing problem (MLRP) is combined with the facility location and the vehicle routing decision and satisfied the diff...

The main objective of this study is to reduce optimal vibration suppression of Timoshenko beam under non-periodic step and impulse inputs. Cantilever beam was modeled by Timoshenko theory and finite element numerical method. Stiffness (K), mass (M), and damping (C) matrices are extracted. Then, in order to control structure vibration, piezoelectric patches were used due to simultaneous dual beh...

the problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. the purpose of this paper is to develop a vehicle routing problem (vrp) model that addresses stochastic simultaneous pickup and delivery in the urban pub...

a partial least squares (pls) calibration model was developed for the simultaneous spectrophotometricdetermination of pb (ιι), cu (ιι) and ni (ιι) using xylenol orange as a chromogenic reagent. the parameterscontrolling behavior of the system were investigated and optimum conditions were selected. the calibrationgraphs were linear in the ranges of 0.0–9.091, 0.0–2.719 and 0.0–2.381 ppm for lead...

a simple, accurate and precise hptlc- densitometry method for the simultaneousdetermination of abacavir, lamivudine and zidovudine in pharmaceutical tablet has beendeveloped. separation of tablet components was performed on aluminum backed hptlc plates(silica gel 60 f254 20×20 cm with 0.2 mm thickness, camag, muttenz, switzerland ) usingmethanol : chloroform : acetonitrile (4 : 8 : 3 v/v). good...
