This note discusses the relationships among three assumptions which appear frequently in the pricing literature. Each of these assumptions ensures that a “revenue function” is strictly unimodal over the region of interest. The three assumptions are decreasing marginal revenue with respect to demand, decreasing marginal revenue with respect to price and decreasing price elasticity of demand. We ...

We propose a novel approach to executing exhaustive histogram search, which incorporates a process to rotate the template used in a computationally efficient manner, e.g. for tracking applications where object rotation will require template rotation. The method is particularly applicable to rectangular templates as any rotation in the region of interest will greatly reduce the potential for a s...

To bridge the research gap on the issue of metacognition in the IS research, this study examines consumer’s metacognition in the context of B2C e-commerce. Especially, focusing on the e-commerce solution in terms of Electronic Product Catalogs (EPCs), this study attempts to investigate the effect of the IT artefact on consumer’s metacognition in online shopping. From the perspective of cognitiv...

A prototype system performing analysis, indexing and retrieval of pathology images to assist physicians in differential diagnosis of lymphoproliferative disorders is presented. Robust color segmentation is used to automatically analyse regions of interest in images of leukocytes. The shape of leukocyte nuclei, described through similarity invariant shape descriptors, represents the main attribu...

While the under-utilization of licensed spectrum based on measurement studies conducted in a few developed countries has spurred lots of interest in opportunistic spectrum access, there exists no infrastructure today for measuring real-time spectrum occupancy across vast geographical regions. In this paper, we present the design and implementation of SpecNet, a first-of-its-kind platform that a...

During the sales engagement between Infrastructure as a Service (IaaS) cloud provider and its customers, analysis on Return On Investment (ROI) in cloud is critical for developing a service solution and making financial investment commitments. However, cloud providers are often challenged in obtaining information about customers’ existing IT environments, so as to compare the cost of continuing...

We present the simple and fast symmetry plain detection algorithm, that recognizes Falx cerebri curve on each human brain computed thomogrpahy slice. Symmetry curves appear approximately on 30% images and using such images as reference it is possible to determine symmetry plane. We propose an algorithm based on hybrid methods, that allows detect symmetry plane with deviation angle until 25. The...

Several methods have been proposed to analyse trajectory data. However, a few of these methods consider trajectory relations with relevant features of the geographic space. One of the best-known methods that take into account the geographical regions crossed by a trajectory is the SMoT algorithm. Nevertheless, SMoT considers only disjoint geographic regions that a trajectory may traverse, while...

Visual Saliency is the perceptual quality that makes an object or pixel region stand out relative to its neighbors and thus capture viewer attention. Thus Saliency models indicate the region of interest. This paper aims at improving the performance of sketch based image retrieval using saliency detection approach. Several methods have been developed to extract the saliency information from an i...

As financial institutions look for ways to reduce costs, manage risk, and extract more value from exponentially increasing amounts of data, technology will emerge as both a crucial enabler and competitive advantage. Financial institutions that invest in developing and managing more flexible infrastructure for mission-critical workloads will significantly improve return on investment (ROI), decr...
