Single cuff automatic blood pressure (BP) measurements are subject to errors because the BP values are based on statistical estimation rather than on physiological principles. We developed a dual cuff experimental system that uses an arm cuff and a wrist cuff. The wrist cuff function is similar to auscultation. This study concentrated on the determination of systolic, diastolic and mean BP using the...
The Data Over Cable Service Interface Specification (DOCSIS) provides internet access via cable TV networks. The latest version 3.1 replaces the Physical Layer of previous DOCSIS versions. With DOCSIS 3.1, broadband cable network operators want to accelerate their networks to gigabit-per-second speeds. Enhancements include an increased bandwidth per downstream channel of up to 192MHz, Orthogonal Frequency-Division...
The problem of sensor location for fault accommodation problem in nonlinear dynamic systems is considered. Solution of the problem is related to constructing the control law which provides full decoupling with respect to fault effects. The logic-dynamic approach is used to solve the problem. The main features of this approach are: it involves known linear methods that results in possibility to solve...
Modern manufacturing systems based on cyber-physical systems with a growing amount of software allow frequent updates and reconfigurations to adapt the systems to volatile usage scenarios in the production. A diverse system environment arises even for similar or equal subsystems based on the same platform used at different locations. A major challenge for such systems is the regression test after...
Software Cost Estimations (SCEs) are tools that used for the software elements classification with number of factors for overall cost estimation. For example resource availability, milestones, deadlines, skill sets, onshore/offshore ratio, knowledge transition etc. Software cost estimations is one of the efficient way to estimate software product's cost with higher accuracy considering the best quality...
Indoor positioning technique has been attracting more and more attention in recent years. In this paper, we propose a multi-path profile fingerprinting localization system based on software defined radio (SDR) platform. The system initially calibrates the multi-path profile (MP) and received signal strength (RSS) information to construct a fingerprint database. In the online positioning phase, the...
Uncertainty is an inherent property of any measure or estimation performed in any physical setting, and therefore it needs to be taken into consideration when modelling systems that manage real data. Although several modelling languages permit the representation of measurement uncertainty for describing certain system attributes, these aspects are not normally incorporated into their type systems...
To facilitate the sharing and combination of knowledge by Global Software Engineering (GSE) researchers and practitioners, the need for a common terminology and knowledge classification scheme has been identified, and as a consequence, a taxonomy and an extension were proposed. In addition, one systematic literature review and a survey on respectively the state of the art and practice of effort estimation...
Many companies have adopted agile software development (ASD), mainly due to it can handle scarce requirements. However, some unsolved challenges exist in ASD, particularly in global software development (GSD) companies (known as AGSD). These challenges include ASD lax documentation contrasted by the methodological standardization required in GSD, due to its inherent distances. Lax documentation leads...
It is an important research subject to estimate the missing value in the incomplete information system. In this paper, we formally define the incomplete information system, incomplete equivalence class, reflexive neighborhood, granularity, granularity domain, rough granularity domain, neighborhood granularity domain, and the property of neighborhood granularity domain. Then we put forward a new method...
Estimation is very important and integral part of software development life cycle. Without estimation of effort, duration and cost, software cannot be developed. It is important to do accurate estimation as much as possible. Today in Information technology Industry Estimation in agile software development is mostly based on heuristic approaches like expert judgment and planning poker. In absence of...
In this paper, a power analysis of a Nios II processor system is carried out. The methodology of power analysis includes SoPC (System on a Programmable Chip) system integration, architecture design compilation, software program compilation using a toolchain, system simulation and power analysis. In this work, a peak detection algorithm is implemented into the embedded processor system for power analysis...
Performance evaluation of tracking methods includes methods of relative and absolute performance. Absolute tracking performance is the robust end result presented to a user which determines the product solution for real world analysis. However, to achieve robust performance, the tracking method is subject to the sensor data, filtering performance, and associated models, which requires relative performance...
Change impact must be accounted for during effort estimation to provide for adequate decision making at the appropriate moment in the software lifecycle. Existing effort estimation approaches, like the Use Case Point method and the Constructive COst MOdeL, estimate the effort only if the change occurs at one level, for example when a new functionality is added (at functional level). However, they...
A cost cumulative progress curve (called S-curve) is often used as a basis for effective schedule control which is a key to the success of construction projects. In establishing a planned S-curve of a construction project, the cost of each scheduling activity must be determined. Furthermore, the contractual costs associated with the cost items should be fully distributed to all scheduling activities...
Trustworthy effort estimation for a software project remains one of the biggest challenges for developer. Software effort estimation is the initial phase between the client and the business enterprise. So the association begins with effort estimation. Trustworthiness increases accurate estimation. Organizations turned toward GSD because it benefits with shorter development cycle. This paper presents...
Application of neural networks for direct prediction of lateral-directional force and moments coefficients from the measured flight data of the research aircraft is proposed in this paper. Proposed model of neural networks appears to be a suitable practical approach to develop relationship between flight variables. This relationship eliminates the need of aerodynamic model as well as thrust model...
This paper discusses assessment of faculty performance. Based on the structure oriented evaluation model a corresponding methodology is presented. The advantage of this approach is that the evaluation is oriented towards the logical structure of evaluation goal whereby in contrast to linear evaluation models the use of weight factors can be avoided.
In a software development project, project management is indispensable, and effort estimation is one of the important factors on the management. To improve estimation accuracy, outliers are often removed from dataset used for estimation. However, the influence of the outliers to the estimation accuracy is not clear. In this study, we added outliers to dataset experimentally, to analyze the influence...
Most of network operation/management tasks such as traffic accounting, traffic engineering, and network design require an accurate and timely network Traffic Matrix (TM). A TM presents the network traffic volume between origin and destination (OD) nodes. Many network management methods assumed that an accurate traffic matrix is given by other network entities, but this is not true. To apply those...
