The present work aims to exploit the thermal performance of a packed bed combined sensible & latent heat storage unit with an integrated solar source. A cylindrical insulated tank in Thermal Energy Storage (TES) is filled spherical capsules separately which contains phase change material (PCM) as paraffin wax and stearic acid. PCM usage has benefits that it can be used management tool reduc...

This paper aims to investigate the energy efficiency of PCM-concrete wallboards using experimental and numerical approaches. First, a laboratory work was performed manufacture mixtures with different proportions PCMs. Then, an innovative bench test based on transient plane source theory used for thermal analysis mixtures. Besides, simulation by finite element method carried confrontation result...

Cascaded thermal storage, consisting of multiple Phase Change Materials (PCMs) with different melting temperatures, has been proposed to solve the problem of poor heat transfer caused by unavoidable decrease of temperature differences during heat exchange process. This paper conducts a theoretical study of the overall thermal performance for a cascaded thermal storage system. Both heat transfer...

Distributed Interactive Applications (DIAs) enable geographically dispersed users to interact with each other in a virtual environment. A key factor to the success of a DIA is the maintenance of a consistent view of the shared virtual world for all the participants. However, maintaining consistent states in DIAs is difficult under real networks. State changes communicated by messages over such ...

These studies aim to investigate subcellular distribution of angiotensin II (ANG II) in rat luteal cells, identify other bioactive angiotensin peptides, and investigate a role for angiotensin peptides in luteal steroidogenesis. Confocal microscopy showed ANG II distributed within the cytoplasm and nuclei of luteal cells. HPLC analysis showed peaks that eluted with the same retention times as AN...

We present a unifying approach to multiple testing procedures for sequential (or streaming) data by giving sufficient conditions for a sequential multiple testing procedure to control the familywise error rate (FWER). Together we call these conditions a "rejection principle for sequential tests," which we then apply to some existing sequential multiple testing procedures to give simplified unde...

Motivated in part by a problem of combinatorial optimization and in part by analogies with quantum computations, we consider approximations of orthogonal matrices U by “non-commutative convex combinations”A of permutation matrices of the type A = P Aσσ, where σ are permutation matrices and Aσ are positive semidefinite n × n matrices summing up to the identity matrix. We prove that for every n× ...

{P1,P2}-Nekrasov matrices represent a generalization of Nekrasov via permutations. In this paper, we obtained an error bound for linear complementarity problems fP1; P2g-Nekrasov matrices. Numerical examples are given to illustrate that new can give tighter results compared already known bounds when applied Also, presented max-norm the inverse in block case, considering two different types gene...
