Consider a tandem queue of two single-server stations with only one server for both stations, who may allocate a fraction α of the service capacity to station 1 and 1−α to station 2 when both are busy. A recent paper treats this model under classical Poisson, exponential assumptions. Using work conservation and FIFO, we show that on every sample path (no stochastic assumptions), the waiting tim...

We propose in this paper an integrated approach that enables the management of Web service transactions. Compared to the existing Web management solutions, it targets to efficiently manage multi-tier Web transactions. It has one unique feature: While the monitoring of Web traffic is done at multiple levels: network, transport, application, and transaction layers, traffic associated with a multi...

Highway assistance services, also called the freeway service patrols (FSPs), are one of the main approaches used by incident management programs. The objective of this study was to investigate the factors that contribute to people choosing to rely on the highway assistance services (FSP) in comparison to private assistance services such as the Automobile Association of America (AAA). Further th...

This article considers the process of development agricultural cooperatives in Ukraine. The data indicators State Statistics Service Ukraine, Unified Register Enterprises and Organizations Ukraine by organizational legal forms were taken as a basis. Data from official report Ministry Agrarian Policy Food also taken. study was conducted several stages. First, with help Service, table number to d...

Descriptions of four proposals submitted to eRENA by three artists. These proposals form a basis for activities in eRENA years 2 and 3, especially in the “open” Work Package 7. In the proposals links with and aesthetic expressions of the themes in work packages 4, 5 and 6 have also been considered and promoted. The proposals strongly connect to the production themes of work package 4, the crowd...

We present a method to generate models for trees in which we first create a weighted graph, then places endpoints and root point and plan least-cost paths from endpoints to the root point. The collection of resulting paths form a branching structure. We create a hierarchical tree structure by placing subgraphs around each endpoint and beginning again through some number of iterations. Powerful ...

We consider the possibility that weak interactions' common with all other known interactions~o in fact enjoy a left-right symmetry manifest in the Hamiltonian, and that parity nonconservation stems from the spontaneous breakdown of this symmetry. We show that this picture is experimentally distinguishable from the conventional one in which parity nonconservation stems from the Hamiltonian. The ...

This deliverable reports on the results from the WebSand work package on information-flow control. These results underpin a framework for decentralized confidentiality and integrity policies but also include investigations on how to these policies can be enforced.

It is studied how the introduction of ordered hierarchies in 4-regular grid network structures decreases distances remarkably, while at the same time allowing for simple topological routing schemes. Both meshes and tori are considered; In both cases non-hierarchical structures have powerlaw dependencies between the number of nodes and the distances in the structures. The perfect square mesh is ...

M-learning web based applications are a particular case of web applications designed to be operated from mobile devices. Also, their purpose is to implement learning aspects. Project management of such applications takes into account the identified peculiarities. M-learning web based application characteristics are identified. M-learning functionality covers the needs of an educational process....
