Routing protocols based on topology control are significantly important for improving network longevity in wireless sensor networks (WSNs). Traditionally, some WSN routing protocols distribute uneven network traffic load to sensor nodes, which is not optimal for improving network longevity. Differently to conventional WSN routing protocols, we propose a dynamic hierarchical protocol based on co...

nowadays in commercial contracts, parties communicate with together using standard forms. both the party's standards forms usually contain a description of the subject-matter, the price, the quantity and the delivery terms. such a situation is called the battle of forms. in such a case some questions are raised. does the exchange of the conflicting forms create a contract? if so, what are ...

Blackwell approachability is a framework for reasoning about repeated games with vector-valued payoffs. We introduce predictive approachability, where an estimate of the next payoff vector given, and decision maker tries to achieve better performance based on accuracy that estimator. In order derive algorithms we start by showing powerful connection between four well-known algorithms. Follow-th...

The article presents the results of analysis compliance civil legislation Ukraine with European approaches to guaranteeing freedom contract and its restrictions. normative consolidation in countries (France, Germany, Slovakia, Poland, Romania) has been studied. It was found that is limited order maintain public order, good morals, protection certain categories contractors (consumers). In France...

performance of contract in many situations is not possible without cooperation from the side of the obligee, and he/she has a duty to do all acts which are necessary to make enable the obligor for contract performance. for example, the execution of medical contract depends on patient’s cooperation. all items of such duty are not capable to cite in different kinds of contracts and in some cases ...
