Anomaly Detection in Cloud Components

Cloud platforms, under the hood, consist of a complex inter-connected stack of hardware and software components. Each of these components can fail which may lead to an outage. Our goal is to improve the quality of Cloud services through early detection of such failures by analyzing resource utilization metrics. We tested Gated-Recurrent-Unit-based autoencoder with a likelihood function to detect anomalies in various multi-dimensional time series and achieved high performance.Comment: Accepted for publication in Proceedings of the IEEE International Conference on Cloud Computing (CLOUD 2020).

Consumers\u27 Preferred Body Scanning Technology: A Comparison

Poor fit of apparel products has been troublesome for both the consumers and manufacturers for many years. The acquisition of a correct set of body measurements is crucially important for achieving proper fitting apparel. Three-dimensional body scanning technology has been recognized as a promising alternative to the traditional measuring tape method of obtaining body measurements. Three-dimensional body scanners are quick, efficient, highly reproducible, and largely free of error related to human intervention. The purpose of this study was to investigate consumers’ preferred type of body scanning technology. Three types of body scanners (traditional body scanner, suit-based body scanner, and mobile-based body scanner) were compared using the Technology Acceptance Model (Davis, 1989) as the theoretical framework. Consumers’ perception on usefulness and ease of use were compared among the three scanner types. An online survey was administered using Qualtrics® software for data collection. Data included 382 responses, out of which only 220 were valid. Data was analyzed using SAS® software to test formulated hypotheses. Findings indicated that participants’ perceived usefulness did not vary across the three types of body scanners, but the mobile-based body scanner was perceived to be easier to use than the traditional body scanner. The suit-based body scanner was perceived to be easier to use by men. Gender did not have any significant effect in the preference of the traditional and the suit-based body scanner, but gender was a significant source of variation in preference of the mobile-based body scanner

Inflation Targeting as the Monetary Policy Framework: Bangladesh Perspective

Inflation targeting strategy has become a widely accepted monetary policy framework in many countries all over the world. Our study finds that the central bank of Bangladesh is neither inflation targeting nor does follow any other rule-guided monetary policy, rather the policy is formulated with substantial discretion under the guidelines of donor agencies. This paper provides the evidence that monetary sector of Bangladesh economy has gained considerable degree of maturity and fulfils a number of prerequisites to adopt inflation targeting strategy. Using data over 1980-2010 we estimate an error correction model in order to examine if interest rate policy could fight the inflation. This is evident that deviation in inflation from target can be corrected via the changes in interest rate. Empirical findings jointly with few descriptive statistics provide strong evidence to recommend inflation targeting as the monetary policy strategy for Bangladesh.Bangladesh, Inflation Targeting, Monetary Policy.
