The problem of determining exact expressions for the effective stiffness tensor macroscopically anisotropic, two-phase composite media of arbitrary microstructure in arbitrary space dimension d is considered. We depart from previous treatments by introducing an integral equation for the “cavity” strain field. This leads to new, exact series expansions for the effective stiffness tensor of macro...

This research proposal presents a novel study that aims to contribute to the understanding of factors that impact on the performance of Australian university business school websites. The proposed study addresses the current limitations of website performance measurement and incorporates a multilevel perspective that accounts for user and organisational perspectives on website performance. This...

We introduce a robust method for computing viscous and viscoelastic two-phase bubble and drop motions. Our method utilizes a coupled level-set and volume-of-fluid technique for updating and representing the air-water interface. Our method introduces a novel approach for treating the viscous coupling terms at the air-water interface; these improvements result in improved stability for computing ...

We consider the topic of partitioning unstructured finite element meshes by a class of multilevel graph partitioning algorithms. Two issues are studied, where the first issue concerns the coarsening phase in such multilevel graph partitioning algorithms. In particular, we propose a new heuristic for matching the vertices of a graph during the coarsening phase. We compare our heuristic with two ...

In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.

In a recent article [1], the authors report evidence for an intriguing two-phase behavior of financial markets when studying the distribution of volume imbalance (Ω) conditional to the local intensity of its fluctuations (Σ). We show here that this apparent phase transition is a generic consequence of the conditioning and exists even in the absence of any non trivial collective phenomenon. More...

With the emergence of distributed systems, the problem of task scheduling has been arousing attention in recent past. Task scheduling is a NP-complete problem and it is more complicated under the distributed heterogeneous computing environment. To harness the potential of these systems, efficient scheduling algorithms are needed. This paper proposes a new distributed scheduling algorithm for in...

Road transport makes up a large share of total costs of intermodal transport. In this paper preand endhaulage in the service area of intermodal container terminals is modelled as a Full Truckload Pickup and Delivery Problem. A single container is delivered from the terminal to a customer or picked up at a customer location and returned to the terminal. Customers impose hard time windows. A two-...

We propose a new approach for practical secure two-party computation (2PC) achieving security in the presence of malicious adversaries. Given a program to compute, the idea is to identify subcomputations that depend on only one or neither of the parties’ private inputs. Such computations can be secured at significantly lower cost, using different protocol paradigms for each case. We then show h...

Matrix completion aims to recover an unknown low-rank matrix from a small subset of its entries. In many applications, the rank target is known in advance and this information can be useful process. paper, first, we revisit recently proposed rank-based heuristic for “known-rank” establish condition under which generated sequence quasi-Fejér convergent solution set. Then, by including accelerati...
