Purpose: To explore the implications for all employees’ psychological contracts of a forced change from permanent to temporary employment status for some employees within an organisation. Methodology/Approach: A random sample of 30 employees, stratified by employment status was selected. Each employee undertook a structured card sort of possible emotional responses to change followed by an in-d...

In the visual cortex, many neurons respond preferentially to one direction of motion. Maps of direction preference vary in appearance between species and cortical areas. We propose that the observed variability in map appearance re/ect the variability in intra-cortical circuits as a consequence of wire length minimization. This hypothesis allows us to bypass a detailed developmental analysis of...

It may be maintained by some that a discussion of the benefits of computer assisted cartography for map reading is premature, and in fact, it may correctly be pointed out that the testing by cartographers of map reading abilities on computer produced maps has not even begun as yet in a systematic way. This state of affairs is especially true of the testing of map reading abilities on 'temporary...

Two-dimensional maps of orientation and direction preference were made in area 18 of the cat's visual cortex using multiple electrode penetrations 150-300 micron apart. The maps were then analyzed by autocorrelation and Fourier transformation. The power spectrum of the orientation map was sharply peaked below the theoretical cutoff frequency for the sampling function (the pattern of electrode p...

Edges are a robust feature for object detection. In this paper, we present an edge-based background modeling method for the detection of moving objects. The edges in the image frames were mapped using robust Canny edge detector. Two edge maps were created and combined to calculate the ultimate moving-edge map. By selecting all the edge pixels of the current frame above the defined threshold of ...

The performance of dynamic path following of a wheeled mobile robot with nonholonomic constraints is highly affected by its initial states, because nonholonomically constrained system cannot guarantee the asymptotic stability for one equilibrium point of which errors and the time derivative of errors are zero. For this reason, the dynamic path following may yield poor performance with some init...

Maximum a-posteriori (MAP) estimation is an important task in many applications of probabilistic graphical models. Although finding an exact solution is generally intractable, approximations based on linear programming (LP) relaxation often provide good approximate solutions. In this paper we present an algorithm for solving the LP relaxation optimization problem. In order to overcome the lack ...
