In this article, we are concerned with tracking an object of interest in video stream. We propose an algorithm that is robust against occlusion, the presence of confusing colors, abrupt changes in the object feature space and changes in object size. We develop the algorithm within a Bayesian modeling framework. The state space model is used for capturing the temporal correlation in the sequence...

In this paper, we model a specific relay channel named relay multiple access channel (RMAC) aiming at providing a clue to select the relay node in multiple access channels such as the uplink of cellular communication system. In this channel, the relay node not only aids to send the information of the source but also sends its private message to the destination. We derive the achievable rate reg...

This paper describes an expansion of the Viterbi algorithm in a cursive script word recognizer based on Hidden Markov Models (HMM) that allows the detection of subwords. The advantage of word recognizers based on HMMs is that there is no need for a segmentation of the word image into single letters. In common systems segmentation still has to take place on a word level which rises problems in m...

Background: The key challenge is how to encourage and retain health professionals in their work location. There is a list of policy options for this purpose but applying an appropriate and effective set of strategies requires a country level research. Our study aimed to identify retention strategies for neurosurgeons and examine both the importance and feasibility of the identified strategies u...

As countries around the world struggle to provide oncology care and treatment to their populations, nurses, as the largest healthcare workforce, are faced with the challenge of obtaining, maintaining, and developing specialized oncology nursing knowledge and expertise. Strategies that can be deployed at a local level to support nurses with integrating new knowledge into practice are important i...

De Vrijer has presented a proof of the finite developments theorem which, in addition to showing that all developments are finite, gives an effective reduction strategy computing longest developments as well as a simple formula computing their length. We show that by applying a rather simple and intuitive principle of duality to de Vrijer’s approach one arrives at a proof that some developments...

A hybrid approach that combines the (1+1)-ES and threshold selection methods is developed. The framework of the new experimentalism is used to perform a detailed statistical analysis of the effects that are caused by this hybridization. Experimental results on the sphere function indicate that hybridization worsens the performance of the evolution strategy, because evolution strategies are well...

Throughout their lives, women provide for their own and their children's and grandchildren's needs and thus must minimize their risk of incurring physical harm. Alliances with individuals who will assist them in attaining these goals increase their probability of survival and reproductive success. High status in the community enhances access to physical resources and valuable allies. Kin, a mat...

The main goal of this commentary is to provide a brief checklist proposal for a possible second meeting with the patient, particularly when prescriptions and therapeutic indications provided in the first meeting were not totally or partially followed. In the second meeting please ask yourself the following question: “Where was my behavior lacking in the first meeting? In the “relationship,” “co...
