System landscapes within logistical scenarios is highly heterogenic. Adding specific mechanisms, e.g. to support planing, monitoring and analyses for fully electrical powered vehicles, could become a mess or at least a challenge. While our project Smart City Logistic (SCL) is trying to manage this extension for multiple logistic scenarios, other projects want to do comparable system extensions as...
A service-oriented architecture (SOA)-based application is composed of a number of distributed and loosely-coupled services which are interconnected to accomplish a more complex functionality. The main security challenge in SOA is that we cannot trust the participating services in a service composition to behave as expected all the time. Moreover, the chain of all services involved in an end-to-end...
The paper reported a field survey that sought to examine the technical implications in the adoption of a Global System for Mobile communication GSM-based metering system in the New Juaben Municipality. Both simple random sampling and interview guide methods were used. The issues considered under the study were; understanding of a GSM-based metre reading, mobile phone penetration among consumers, reliability...
In order to permit competitive, the industry must ensure its technology position, companies must be able to develop services and products quickly and manage logistics and production systems efficiently. The backbone of a successful operation is a reliable, resilient, and secure communication infrastructure. The effective operation of networks is vital to the efficient governance, management, and monitoring...
The efforts and findings of the last decades of research on the formalization and the verification of Web services have given a certain level of assurance on Web services. However new challenges such as high availability and security issues are not fully addressed. In fact, Web services are exposed to attacks that appear continuously. These issues have naturally paved the way to a new research topic...
The existing electric grid system in Brazil is facing many challenges and this encourages the roll out of smart grid systems to reinforce the existing grid system. In this context, energy companies are seeking for solutions and applications to grow and expand their network improving reliability and coverage. One of the key technologies of smart grid is a two-way communication between smart grid components...
This study relate the audit firms characteristics and the audit quality. Using data from the Portuguese listed companies from the period 2010 to 2014 and using as a proxy of audit quality the type of audit report, the conclusion is that the dimension of the audit firm and the audit fees on the total audit firm's fee influences the audit quality. This study contributes to the literature by studying...
This research work is aimed at the estimated two regression models, with which it is intended to measure the fragility of Ecuadorian companies. Development and scope of the proposed objective, the information in the financial statements of 34.575 both large companies are used, medium, small and micro enterprises that are controlled and monitored by the Superintendency of Companies in 2013, plus a...
Governance of Information Technology (IT) aims to direct and control the current and future use of IT for the benefit of an organization, in order to guide the management of IT organizational resources globally through means and resources such as: access policy, risk management, human resource management, information access, transfer, storage and processing technologies and processes. This article...
In a very short time, the Internet has dramatically changed how we work, live, play, and learn. Yet, we have barely scratched the surface. Using existing and new technologies, we are connecting the physical world to the Internet. It is by connecting the unconnected that we transition from the Internet to the Internet of Everything (IoE). Internet of Everything has top five applications; Traffic monitoring,...
This paper reviews ballast water treatment systems regarding functional and operational problems. Ballast water treatment systems (BWTS) could be in failure or under repair. New invented sensors based on flow measurement methodologies should report malfunctions utilizing satellites. This invention is the solution concerning the quality control of ship's ballast water, and this is the system which...
The chemical industry can be defined as a typical type of plant industry. As it is impossible to see inside of a plant directly, a system; PSS (Production Support System) that enables to monitor a process status with sensors is applied. Since it costs to implement PSS, a company checks the reasonability of the amount of investment from the viewpoints of resource saving, energy saving and man-power...
The challenges related to the monitoring, diagnosis and control of a wind farm are presented. First, Wireless Sensors Networks are investigated, from an Internet of Things point of view: the most used and recent routing protocols, and the methods which can secure the network against attacks. As the volume of collected information is very large and diverse, big data processing frameworks needed to...
In the design and synthesis of control systems in industrial companies, we have to face lots of unexpected problems caused by interactions between control systems with human operators (automated control systems) and control systems with no human operators (automatic control systems). While there are plenty of recommendations for design, synthesis and optimization of automatic control systems, in case...
As part of the conducted research, methodological guidelines have been justified and drawn up on strategy forming for developing a retail gas station chain of an oil company based on economic value added.
Object: Research of methods and tools for monitoring the company's risks in order to control and adjust risk management in the current economic conditions. Methods: The paper examines the methodological basis in order to form a procedure for observation and analysis of risks for further application of methods to influence risky events. The possibility and expediency of introducing effective performance...
Similar to many modern applications, enterprise applications like SAP are often implemented in a distributed fashion and consequently suffer from network degradations resulting in impairments like increased loading delays. While the influence of these impairments on the perceived quality of users is well researched for consumer applications and network services, their impact in a business environment...
Continuous Planning (CP) is a management practice inspired in principles from the agile and lean software development. In this paper, we present in detail the case of a small Brazilian software company on moving from an agile background towards CP, due to a constant changing environment. Furthermore, we discuss the reported case in the light of the technical literature on CP. Although observing evidence...
In their mission of collecting, analyzing and disseminating statistic data, the National Institutes of Statistics are more and more confronted with personal data management. With the advent of the “Open Data” [1], the need for data diffusion and to establish a link between databases created during the surveys and censuses, are necessary for planning, monitoring and activities evaluation, in a context...
Accurate capacity measurement of Internet services is critical to ensure high-performing production computing environments. In this work, we present our solution of performing accurate capacity measurement. Referred to as “LiveRedliner”, it uses live traffic in production environments to drive the measurement, hence avoiding many pitfalls that prevent capacity measurement from obtaining accurate values...
