This work provides new results for the separated encoding of correlated discrete memoryless sources. We address the scenario where an arbitrary number of auxiliary sources (a.k.a. helpers) are supposed to help decode a single primary source errorless. The rate-distortion analysis of such a system establishes the so-called many-help-one problem. We focus on the case in which the auxiliary source...

This paper presents a novel approach to the weak classifier selection based on the GentleBoost framework. We include explicitly the notion of neighborhood in one of the most common weak learner in boosting, the decision stumps. The availability of neighboring points adds a new parameter to the decision stump, the feature set (i.e. neighborhood), and turns the single branch selection of the deci...

• Outcomes of 13 participatory foresight workshops are compared. Small farms' and businesses' contribution to food security is important in three the four considered scenarios. Concerns on small farms businesses relate broader rural setting. Weak collective action will hamper adaptive capacity farms.

The ability to detect and identify gaseous effluents is a problem that has been pursued with limited success. It has been shown to be possible using the Invariant algorithm on synthetic hyperspectral scenes with a strong single gas release. That however, is a very specific case and leaves room for further investigation. This study looks at more realistic detection and release scenarios. Our imp...

Passwords have to be secure and usable at the same time, a trade-off that is long known. There are many approaches to avoid this trade-off, e.g., to advice users on generating strong passwords and to reject user passwords that are weak. The same usability/security trade-off arises in scenarios where passwords are generated by machines but exchanged by humans, as is the case in pre-shared key (P...

Article history: Received 22 December 2013 Accepted 24 February 2014 Available online 20 March 2014 When developing foresight, it is essential to consider the information on which this activity is based. Weak signals, also conceptualised as trends, can be considered the most relevant input for developing foresight in an organisation. While detecting weak signals has traditionally relied on the ...

In this paper, we investigate the ergodic rate for a device-to-device (D2D) communication system aided by a two-way decode-and-forward (DF) relay node. We first derive closed-form expressions for the ergodic rate of the D2D link under asymmetric and symmetric cases, respectively. We subsequently discuss two special scenarios including weak interference case and high signal-to-noise ratio case. ...

Based on the promising developments in Cloud Computing technologies in recent years, commercial computing resource services (e.g. Amazon EC2) or software-as-a-service offerings (e.g. Salesforce.com) came into existence. However, the relatively weak business exploitation, participation, and adoption of other Cloud Computing services remain the main challenges. The vague value structures seem to ...

BACKGROUND AND PURPOSE Scenarios are used as the basis from which to evaluate the use of the components of evidence-based practice in decision making, yet there are few examples of a standardized process of scenario writing. The aim of this paper is to describe a step-by-step scenario writing method used in the context of the authors' curriculum research study. METHODS Scenario writing teams ...

The abundant natural resources can bring either positive or negative impact to the country’s economy depending on the macroeconomic policies. Mongolia has massive mineral resource dominated by coal, copper, and gold. The Government of Mongolia has started to implement a number of infrastructure projects to decrease the mining project’s cost burden caused from the country’s weak infrastructure. ...
