Intrinsic timing uncertainties present in modern hardware platforms have motivated the use of Extreme Value Theory (EVT) to timing analysis, however, the timing behaviour of a task may not entirely fulfil the necessary assumptions. To deal with this difficulty, randomisation at the hardware level has been proposed as a means of facilitating the use of statistical timing analysis. However, it has been...
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...
The problem of animal social behavior estimation has two components: automatically tracking a number of identical objects with a large number of collisions and calculating indexes for behavior description. In this paper a tracking algorithm has been proposed for a sequence of depth images. This algorithm combines detection and tracking methods. The proposed algorithm is highly reliable: in the worst...
We compare five slope correction methods developed by Walter et al., Montes et al., Schleppi et al., España et al., and Gonsamo et al. (referred to as WAL, MON, SCH, ESP, and GON, respectively) using artificial fisheye pictures simulated by graphics software and a lookup table (LUT) retrieval method. The LUT is built by simulating the directional gap fraction as a function of leaf area index (LAI)...
Models for estimation of land remote sensing satellites periodicity is under consideration in the paper. The models were implemented in the software, developed in Delphi programming support environment. Some results are presented.
Analogy-based software development effort estimation methods have proved to be a viable alternative to other conventional estimation methods since they mimic the human problem solving approach. However, they are limited by their inability to correctly handle categorical data. Therefore, we have proposed, in an earlier work, a new approach called fuzzy analogy which extends classical analogy by incorporating...
The quality of empirical studies is critical for the success of the Software Engineering (SE) discipline. More and more SE researchers are conducting empirical studies involving the software industry. While there are established empirical procedures, relatively little is known about the dynamics of conducting empirical studies in the complex industrial environments. What are the impediments and how...
Based on the molecular structure topological index Bm1, Bm2, Bm3, with 14 kinds of persistent organic compounds of environmental parameters associated with LgKoc, LgKow and LgKoA using MATLAB software to multiple linear regressions was fitted regression equation. The use of multiple linear regression test of significance, results show that the equation is significant. Estimations are well coincident...
When designing the solar power generation system is in face of the variety of solar cell, the user must consider not only the needs of the load and also the price of the solar cell, weight, annual power generating capacity (APGC) and the maximum power. It is an important task to find the optimal power generation system with many parameters. Therefore, this paper presents an estimation method based...
The paper presents a method for estimation of the initial position in a SRM drive which is provided with an incremental encoder. This is necessary immediately after power up, before the motor starts and the index signal is received. On the other hand, to calculate the rotor position when the motor runs the control system should know the displacement of the index signal from the reference position...
Through analyzing the factors affecting software trustworthy, established the index system of trustworthy software estimation. Apply Analytic Hierarchy Process (AHP) to determine the relative importance of factors and indicator items affecting software trustworthy, and then determine the score of estimation index system through fuzzy estimation model, use the combination of both to measure software...
This paper focuses on the comparison of suitable methodologies that can help identifying the risk factors more appropriately. For this purpose a comparative study between the available techniques, namely Experience & Knowledge (EK), Questionnaire (Q) and Direct Communication (DC) has been made based on the survey that has been conducted on more than 100 respondents. By tabulating the results the...
Along with urbanization, traffic congestion increasingly affects people. Evaluation index is of great value to describe traffic jams of the city's road network or specific region, but in the field of the road intersection, current study on evaluation indicators does not sound. In this paper, point sample method is adopted to conduct field estimation on five districts and 15 Intersections of Beijing...
Generally traffic jams are grown from single spots such as intersections which have key positions in urban transportation, then the small jams came into bigger ones, until the whole region was stopped up. In order to measure the extent of traffic jams, it's necessary to define an index. Based on regression analysis on the data from 15 Intersections of 5 Beijing Districts, the Intersection Approach...
As part of the urban transportation, intersections belong to quasi-public goods. Individual vehicles will not affect others on the same intersection when traffic is smooth. But once the traffic flow exceeds the critical point, intersections' non-competitive character will disappear and exclusionary becomes conspicuous, showing all levels of traffic jams. This article first combines the transportation...
The new mathematical model introducing a quality index of the software project size determined at the testing stage for the software reliability estimation and prediction is suggested.
The methodology of message analysis plan formation by the information network operator about the parameters of its functioning and state is examined in this article.
Correct software cost estimation is important in software engineering. So it is significant to reasonably evaluate current lots of software cost estimation methods and subsequently select the most suitable one. The evaluation framework of software cost estimation methods is brought forward. The framework summarizes all aspects that should be considered by estimation methods. Fuzzy-Grey comprehensive...
Software engineering is continuously facing the challenges of growing complexity of software packages and increased level of data on defects and drawbacks from software production process. This makes a clarion call for inventions and methods which can enable a more reusable, reliable, easily maintainable and high quality software systems with deeper control on software generation process. Quality...
Based on the fundamental quality data given by the software development centre and in accordance of the principle analysis, the project quality standard had undertaken analysis and predication. Three stages were respectively as follows: project estimation, project budget and project propagation. The three stages had co-related the differential value of workload, changes of project scope and quality...
