Leveraging simulation practice in industry through use of desktop grid middleware
This chapter focuses on the collaborative use of computing resources to support decision making in industry. Through the use of middleware for desktop grid computing, the idle CPU cycles available on existing computing resources can be harvested and used for speeding-up the execution of applications that have ânon-trivialâ processing requirements. This chapter focuses on the desktop grid middleware BOINC and Condor, and discusses the integration of commercial simulation software together with free-to-download grid middleware so as to offer competitive advantage to organizations that opt for this technology. It is expected that the low-intervention integration approach presented in this chapter (meaning no changes to source code required) will appeal to both simulation practitioners (as simulations can be executed faster, which in turn would mean that more replications and optimization is possible in the same amount of time) and the management (as it can potentially increase the return on investment on existing resources)
Integrating BOINC with Microsoft Excel: A case study
The convergence of conventional Grid computing with public resource computing (PRC) offers potential benefits in the enterprise setting. For this work we took the popular PRC toolkit BOINC and used it to execute a previously monolithic Microsoft Excel financial model across several commodity computers. Our experience indicates that speedup approaching linear may be realised for certain scenarios, and that this approach offers a viable route to leveraging idle desktop PCs in the enterprise
Probably Unknown: Deep Inverse Sensor Modelling In Radar
Radar presents a promising alternative to lidar and vision in autonomous
vehicle applications, able to detect objects at long range under a variety of
weather conditions. However, distinguishing between occupied and free space
from raw radar power returns is challenging due to complex interactions between
sensor noise and occlusion.
To counter this we propose to learn an Inverse Sensor Model (ISM) converting
a raw radar scan to a grid map of occupancy probabilities using a deep neural
network. Our network is self-supervised using partial occupancy labels
generated by lidar, allowing a robot to learn about world occupancy from past
experience without human supervision. We evaluate our approach on five hours of
data recorded in a dynamic urban environment. By accounting for the scene
context of each grid cell our model is able to successfully segment the world
into occupied and free space, outperforming standard CFAR filtering approaches.
Additionally by incorporating heteroscedastic uncertainty into our model
formulation, we are able to quantify the variance in the uncertainty throughout
the sensor observation. Through this mechanism we are able to successfully
identify regions of space that are likely to be occluded.Comment: 6 full pages, 1 page of reference
A proposed case for the cloud software engineering in security
This paper presents Cloud Software Engineering in Security (CSES) proposal that combines the benefits from each of good software engineering process and security. While other literature does not provide a proposal for Cloud security as yet, we use Business Process Modeling Notation (BPMN) to illustrate the concept of CSES from its design, implementation and test phases. BPMN can be used to raise alarm for protecting Cloud security in a real case scenario in real-time. Results from BPMN simulations show that a long execution time of 60 hours is required to protect real-time security of 2 petabytes (PB). When data is not in use, BPMN simulations show that the execution time for all data security rapidly falls off. We demonstrate a proposal to deal with Cloud security and aim to improve its current performance for Big Data
Cloud Computing Tipping Point Model
Recently a continuing trend toward ITindustrialization has grown in popularity. IT services deliveredvia hardware, software and people are becoming repeatableand usable by a wide range of customers and service providers.This is due, in part, to the commoditization and standardizationof technologies, virtualization and the rise of service-orientedsoftware architectures, and (most importantly) the dramaticgrowth in popularity/use of the Internet and the Web. Takentogether, they constitute the basis of a discontinuity that amountsto a new opportunity to shape the relationship between those whouse IT services and those who sell them. The discontinuity impliesthat the ability to deliver specialised services in IT can be pairedwith the ability to deliver those services in an industrialised andpervasive way. The reality of this implication is that users of ITrelatedservices can focus on what the services provide them, ratherthan how the services are implemented or hosted. Analogous tohow utility companies sell power to subscribers, and telephonecompanies sell voice and data services, some IT services suchas network security management, data centre hosting or evendepartmental billing can now be easily delivered as a contractualservice. This notion of cloud computing capability is gatheringmomentum rapidly. However, the governance and enterprisearchitecture to obtain repeatable, scalable and secure businessoutcomes from cloud computing is still greatly undefined.This paper attempts to evaluate the enterprise architecturefeatures of cloud computing and investigates a model that an ITorganisation can leverage to predict / evaluate the âtipping pointâwhere an organisation can make an objective decision to investin cloud computing. Current research results are attempting tobuild a quantitative and qualitative service centric frameworkby mapping cloud computing features with ValIT and COBITindustry best practices

Forecasting Cryptocurrency Value by Sentiment Analysis: An HPC-Oriented Survey of the State-of-the-Art in the Cloud Era
This chapter surveys the state-of-the-art in forecasting cryptocurrency value by Sentiment Analysis. Key compounding perspectives of current challenges are addressed, including blockchains, data collection, annotation, and filtering, and sentiment analysis metrics using data streams and cloud platforms. We have explored the domain based on this problem-solving metric perspective, i.e., as technical analysis, forecasting, and estimation using a standardized ledger-based technology. The envisioned tools based on forecasting are then suggested, i.e., ranking Initial Coin Offering (ICO) values for incoming cryptocurrencies, trading strategies employing the new Sentiment Analysis metrics, and risk aversion in cryptocurrencies trading through a multi-objective portfolio selection. Our perspective is rationalized on the perspective on elastic demand of computational resources for cloud infrastructures
