Portals and Task Innovation: A Theoretical Framework Founded on Business Intelligence Thinking

The main aim of this study is to develop a theoretical framework for the success of Web portals in promoting task innovation. This is deemed significant as yet little research has tackled this important domain from the business intelligence perspective. The D&M IS Success Model was used as a foundational theory and then was refined to match the context of the current research. Importantly, in this study, system quality and information quality constructs were defined on the basis of portals' characteristics since a mapping was conducted between the most significant functions and features of Web portals and quality constructs. The developed framework is deemed useful for theory and practice. From theoretical perspective, the dimensions that affect the perceived quality of Web portals are identified, and the measures that affect each quality dimension are also defined. On the practical level, contributions gained by this study can be observed in terms of the benefits decision makers, strategists, operational employees and IT developers can gain. Assessing portals success in improving task innovation is important to help managers (i.e. decision makers) in making appropriate decisions concerning the adoption of portals' technology, by weighing its benefits against the costs needed to establish and run such a technology. Moreover, assessing Web portals' success gives some insight to IT developers and designers concerning what aspects should be taken when designing and establishing high quality portals, and what functions and features should be contained that would affect the perceived quality of portals and therefore users' intention to use portals.

Establishing Virtual R&D Teams: Obliged Policy

In a global and technology oriented world the requirements that products and services have to fulfill are increasing and are getting more complicated. Research and development (R&D) is becoming increasingly important in creating the knowledge that makes research and business more competitive. Companies are obliged to produce more rapidly, more effectively and more efficiently. In order to meet these requirements and to secure the viability of business processes, services and products R&D teams need to access and retrieve information from as many sources as possible. From the other perspective virtual teams are important mechanisms for organizations seeking to leverage scarce resources across geographic and other boundaries moreover; virtual collaboration has become vital for most organizations. This is particularly true in the context of designing new product and service innovation. Such collaboration often involves a network of partners located around the world. However at the R&D project level, dealing with such distributed teams challenges both managers and specialists. In new product development, it is necessary to put together the growing different capabilities and services with the goal, through cooperation between suppliers and customers, service providers and scientific institutions to achieve innovations of high quality. In this paper based on comprehensive literature review of recent articles, at the first step provides an primary definition and characterization of virtual R&D team; next, the potential value created by virtual R&D teams for new product development is explored and lastly along with a guide line for future study, it is argued that the establishing of virtual R&D teams should be given consideration in the management of R&D projects.

Compressed Sensing based Protocol for Efficient Reconstruction of Sparse Superimposed Data in a Multi-Hop Wireless Sensor Network

We consider a multi-hop wireless sensor network that measures sparse events and propose a simple forwarding protocol based on Compressed Sensing (CS) which does not need any sophisticated Media Access Control (MAC) scheduling, neither a routing protocol, thereby making significant overhead and energy savings. By means of flooding, multiple packets with different superimposed measurements are received simultaneously at any node. Thanks to our protocol, each node is able to recover each measurement and forward it while avoiding cycles. Numerical results show that our protocol achieves close to zero reconstruction errors at the sink, while greatly reducing overhead. This initial research reveals a new and promising approach to protocol design through CS for wireless mesh and sensor networks.

Design For Change: Information-Centric Architecture to Support Agile Disaster Response

This paper presents a case for the adoption of an information-centric architecture for a global disaster management system. Drawing from a case study of the 2010/2011 Queensland floods, we describe the challenges in providing every participant with relevant and actionable information. We use various examples to argue for a more flexible information dissemination framework which is designed from the ground up to minimise the effort needed to fix the unexpected and unavoidable information acquisition, quality, and dissemination challenges posed by any real disaster.

Analysis of Trim Commands on Overprovisioning and Write Amplification in Solid State Drives

This paper presents a performance model of the ATA/ATAPI SSD Trim command under various types of user workloads, including a uniform random workload, a workload with hot and cold data, and a workload with N temperatures of data. We first examine the Trim-modified uniform random workload to predict utilization, then use this result to compute the resultant level of effective overprovisioning. This allows modification of models previously suggested to predict write amplification of a non-Trim uniform random workload under greedy garbage collection. Finally, we expand the theory to cover a workload consisting of hot and cold data (and also N temperatures of data), providing formulas to predict write amplification in these scenarios.

Empowered Customers in E-Health Business Process

E-health innovations support empowered customers. It offers the ability for customers to have greater control and ready access applications of health information, clinical information, and social interaction between interested groups. However, providing empowerment in any state of interaction levels to customers (patients) in a healthcare organization is challenging tasks. Customers are empowered in the sense of controlling the process of interaction between a firm with its customers, and among customers themselves. This paper discusses dimension of customers' empowerment in e-health business process. We propose reference model of Personal Health Cycle (PHC) as a holistic view of healthcare business process. The PHC is used to define and distinct electronic health record (EHR) from electronic medical record (EMR) and customers empowerment.

Adding Methodological Testing to Naur's Anti-formalism

Peter Naur is the leading critic of formalist computing because of his extensive writings that disprove the now dominate characterization of human thought as cognitive information processing. Naur criticizes the ideological position that only discourse that adopts computer inspired forms are acceptable. Lakatosian philosophy of the methodology of scientific research programmes (MSRP) is added to Naur's studies to allow testing of computing theories. After discussing Naur's criticism of mechanical cognitive information processing, I show how to add MSRP competition to Naur's descriptive philosophy. Next, Naur's claim that computing can not become scientific until organizational issues involving ideological suppression of discussions of computing and human thinking are solved is corroborated by institutional suppression of my 1970s attempts to criticize structured programming (SP). Various problems in computing related philosophy are discussed. First, I argue that my MSRP based degenerating research programme disproof of SP is better than Naur's programming as a human activity, Demillo's social processes and Fetzer's unprovable causal nature. Three areas for post ideologically based computing study are discussed: computing as a path to rediscovering 19th century conceptions of infinity, axiom of choice testing facilitated by computing and relation to physical theory, and testing concrete complexity methods based on efficiency proof analysis.

Resonant Clocking Circuits for Reversible Computation

A mechanism for the reduction of dynamic energy dissipation in the computing circuit is described. The resonant circuit with controlled switches conserves the stored energy by recovering upto 90% of energy that would be otherwise lost during logic state transitions. This energy-conserving approach preserves thermodynamic entropy, ideally preventing heat generation in the system. This approach is used in a proposed resonant clocking and logic application without dynamic energy dissipation.

Survey of Multiscale and Multiphysics Applications and Communities

Multiscale and multiphysics applications are now commonplace, and many researchers focus on combining existing models to construct combined multiscale models. Here we present a concise review of multiscale applications and their source communities. We investigate the prevalence of multiscale projects in the EU and the US, review a range of coupling toolkits they use to construct multiscale models and identify areas where collaboration between disciplines could be particularly beneficial. We conclude that multiscale computing has become increasingly popular in recent years, that different communities adopt very different approaches to constructing multiscale simulations, and that simulations on a length scale of a few metres and a time scale of a few hours can be found in many of the multiscale research domains. Communities may receive additional benefit from sharing methods that are geared towards these scales.

Sociotechnical Management Model for Governance of an Ecosystem

This is an opinion paper regarding a proposal of a model for a Ecosystemm Governance. In the globalized world the importance of Information Systems (IS) and Information Technology (IT) become increasingly relevant regarding the requirements imposed by competition. Both the knowledge of the business as the rapid flow of information are fundamental for a enterprise decision making. Whereas the basic definition of IT = hardware + software, i.e., tools that has been used to create, store and disseminate data and information in the creation of knowledge, and IS = IT + People + procedures that collect, process and disseminate the information to support decision making, coordination, control, analysis and visualization in the organization [01], it makes implicit the understanding of IS is essential to create competitive companies, to manage global corporations and provide customers with products and services of value. In this work we are correlating IS with the governance of management of an ecosystem. Yet, as IT is redefining the foundations of business, then the customer service, operations, strategies of product marketing and its distribution and even the knowledge management (KM) depends very much, or sometimes even completely, on the IS. The IT and its costs have become a part of day-to-day business [02]. In order to meet this complexity of business needs, today is not possible to disregard the IT and its available resources, which makes very dificult to draw up IS. Therefore, the perspective view of the Sociotehcnical Aspects of an IS are directly concerned with governance and the model proposed regarding an ecosystem. Finally, whereas the summary above, the main objective of this opinion paper is to propose the guidelines for a Sociotechnical Management Model of Governance for an Ecosystem.

CrowdInside: Automatic Construction of Indoor Floorplans

The existence of a worldwide indoor floorplans database can lead to significant growth in location-based applications, especially for indoor environments. In this paper, we present CrowdInside: a crowdsourcing-based system for the automatic construction of buildings floorplans. CrowdInside leverages the smart phones sensors that are ubiquitously available with humans who use a building to automatically and transparently construct accurate motion traces. These accurate traces are generated based on a novel technique for reducing the errors in the inertial motion traces by using the points of interest in the indoor environment, such as elevators and stairs, for error resetting. The collected traces are then processed to detect the overall floorplan shape as well as higher level semantics such as detecting rooms and corridors shapes along with a variety of points of interest in the environment. Implementation of the system in two testbeds, using different Android phones, shows that CrowdInside can detect the points of interest accurately with 0.2% false positive rate and 1.3% false negative rate. In addition, the proposed error resetting technique leads to more than 12 times enhancement in the median distance error compared to the state-of-the-art. Moreover, the detailed floorplan can be accurately estimated with a a relatively small number of traces. This number is amortized over the number of users of the building. We also discuss possible extensions to CrowdInside for inferring even higher level semantics about the discovered floorplans.

Controlling and securing a Digital Home using Multiple Sensor Based Perception system Integrated with Mobile and Voice technology

Fully controlled digital home had always been considered as a luxury of rich people because of excessive cost to install the system. It is now within the reach of mass people with lots of inexpensive cool features. In this paper we have designed and developed a very low cost, efficient and reliable Digital home system. Fully Controlled Digital Home is no more a Luxury. Our proposed system made it affordable. We built a low-cost feature-rich Digital Home System (DHS). Digital Home System is combination of automated services i.e. Electronic Device Controller, IR Security System, Web Desktop, Remote Video Surveillance System and Virtual Mobile by which we can control our home by avoiding old manual processes e.g. our physical presence at home is optional. The System provides some of the modern luxury & security features to us. Now we can control Light, fan, AC or any electronic devices by voice command, Blue-tooth, GPRS or Website. To control the system remotely, GPRS connectivity is added. We can also monitor our home from remote area by using Remote Video Surveillance System. This enables live video into mobile device of the digital home. Moreover, we can also access our PC and do the necessary tasks from any internet enabled computer in the world by using Web Desktop which is specially built for this purpose. Furthermore, access of unauthorized person in the home will be notified by SMS & store the image of the person and also generate a voice alarm. So that ensures the security of our valuable things. Also we can identify and monitor the location of our valuable assets e.g. precious metals remotely. Finally, Virtual mobile application is a Universal mobile Driver by which we can exactly perform some same task e.g. Remote call, Phone book access, SMS read-write of our mobile device from our new invented computer's virtual mobile.

Automatic Electric Meter Reading System: A Cost-Feasible Alternative Approach In Meter Reading For Bangladesh Perspective Using Low-Cost Digital Wattmeter And Wimax Technology

Energy meter reading is a monotonous and an expensive task. Now the meter reader people goes to each meter and take the meter reading manually to issue the bill which will later be entered in the billing software for billing and payment automation. If the manual meter reading and bill data entry process can be automated then it would reduced the laborious task and financial wastage. "Automatic Electric Meter Reading (AMR) System" is a metering system that is to be used for data collecting from the meter and processing the collected data for billing and other decision purposes. In this paper we have proposed an automatic meter reading system which is low cost, high performance, highest data rate, highest coverage area and most appropriate for Bangladesh perspective. In this AMR system there are four basic units. They are reading unit, communication unit, data receiving and processing unit and billing system. For reading unit we identified the disk rotation of the energy meter and stored the data in microcontroller. So it is not required to change the current analog energy meter. An external module will be added with the current energy meter. In the communication unit Wimax transceiver was used for wireless communication between meter end and the server end because of its wide coverage area. In the data receiving and processing unit meter reading will be collected from the transceiver which is controlled by another microcontroller. There will be a computer application that will take the data from the microcontroller. This will also help to avoid any tampering or break down of energy meter. There are various AMR system exists all over the world. Those systems were analyzed and we found they are not feasible for Bangladesh.
