Many full-reference objective metrics require that the original and the degraded video contain the same number of frames. Most codecs are not able to decode the video properly when the video is subject to packet losses and produce incomplete video files with lower number of frames than the original video. In this paper we present a simple method to reconstruct the degraded videos so that it has th
In today’s business landscape the view and role of the customer, or market, in shaping and guiding strategy and the competitive advantage of a business, is given increasing attention within many areas of business theory. By definition the supply chain discipline focuses on suppliers from the perspective of the manufacturer, not customers. However this paper illustrates the use of the supply chain
The direct problem of time dependent electromagnetic scattering in the dispersive sphere is solved by a wave splitting technique. The electric field is expanded in a series involving vector spherical harmonics, leading to a system of wave equations for each term. These systems are reduced to scalar wave equations for each term, which are solved via reflection operators. Some preliminary numerical
Case study is a suitable research methodology for software engineering research since it studies contemporary phenomena in its natural context. However, the understanding of what constitutes a case study varies, and hence the quality of the resulting studies. This paper aims at providing an introduction to case study methodology and guidelines for researchers conducting case studies and readers st
To provide for a high QoS in a cellular network, each call should be assigned to its preferred cell and priority given to already ongoing calls. Herein, a combined speed-sensitive layer selection method and dynamic guard channel scheme, called CLARR, for use in hierarchical networks, is introduced. To reduce the complexity, partially the same speed estimation and measurement procedures are applied
In this study, we present a novel method to isolate and enrich low concentrations of Campylobacter pathogens. This method, Acanthamoeba-Campylobacter coculture (ACC), is based on the intracellular survival and multiplication of Campylobacter species in the free-living protozoan Acanthamoeba polyphaga. Four of the Campylobacter species relevant to humans and livestock, Campylobacter jejuni, C. coli
A continuous review serial production/distribution system with discrete compound Poisson demand for the end product is considered. Unmet demand is back-ordered. Production/transportation times are constant. All deliveries from one stage to the next must be multiples of given batch sizes. The problem of minimizing the holding costs under a fill rate constraint is considered. Using recent results by
This paper develops a very simple test for the null hypothesis of no cointegration in panel data. The test is general enough to allow for heteroskedastic and serially correlated errors, unit-specific time trends, cross-sectional dependence and unknown structural breaks in both the intercept and slope of the cointegrated regression, which may be located at different dates for different units. The l
Laminin-alpha5 chain was localized in all epithelial basement membranes (BMs) of mouse submandibular gland (SMG) from the onset of branching morphogenesis and became restricted to BMs of epithelial ducts in the adult. To investigate whether the laminin-alpha5 chain plays a role in branching morphogenesis, a set of cell-adhesive peptides from the C-terminal globular domains (LG1-5) was tested for t
For real time embedded systems software performance is one of the most important quality attributes. Controlling and predicting the software performance in software is associated with a number of challenges. One of the challenges is to tailor the established and rather general performance activities to the needs and available opportunities of a specific organization. This study presents a qualitat
We present processing technology based on nanoimprint lithography (NIL) and wet etching for fabrication of GaInAs/InP three-terminal ballistic junction (TBJ) devices. To transfer sub-100 nm features into a high-mobility InP-based 2DEG material, we used SiO2/Si stamps made with electron beam lithography and reactive ion etching. After the NIL, the resist residues are removed in oxygen plasma follow
A novel method for the synthesis of spherical molecularly imprinted polymer (MIP) beads by suspension polymerization in mineral oil is described. The usefulness of the method was demonstrated by the synthesis of a propranolol imprinted MIP library. The composition of the library was generated by statistical experimental design. Multivariate data analysis correlated the screening data, obtained by
Structure-property relationships of polymers incorporating Lewis acidic boron in their branched chain architecture were investigated as a function of LiClO4 salt concentration. The polymers were synthesised from boron trioxide, and different poly(ethylene glycol)s (PEGs) and monomethyl ether end-capped PEGs. The PEG-boronate ester polymers based on PEGs having molecular weights equal to, or below,
This article proposes nonparametric inference procedures for analyzing microarray gene expression data that are reliable, robust, and simple to implement. They are conceptually transparent and require no special-purpose software. The analysis begins by normalizing gene expression data in a unique way. The resulting adjusted observations consist of gene-treatment interaction terms ( representing di
In this study the elasto-plastic constitutive equations are reformulated using the assumption of constant strain rate direction within a load increment. This assumption allows the constitutive evolution laws to be rewritten as ordinary differential equations (ODEs). The set of ODEs is reduced using the Krieg and Krieg description of the deviatoric stress space. Although this approach does generall
Polysulfone main chains have been functionalized with hypersulfonated aromatic side chains where the sulfonic acid groups were highly concentrated on a local scale, with two acid groups placed on the same aromatic ring. This molecular design was implemented to promote the nanophase separation that takes place in proton-exchange membranes between the hydrophobic polymer main chain and the hydrophil
