Presents the research results in efficiency assessment of contactless technologies of fare payment implementation on public transport. The project effectiveness assessment methodology has been developed on the synthesis method basis of expert assessments and prof. A. Egorshin's methods. The methodology allows to evaluate several effect types from the project implementation and to perform calculations...
Investigations involving digital forensics typically include file hash matching procedures at one or more steps in the examination. File hash matching is typically done by computing a complete file hash value for each file on a storage device and comparing that to a pre-computed hash list. This work examines how various improvements to the basic technique impact the time required to perform hash matching...
A implantable CPW fed dual folded dipole antenna operating in the ISM band (2.4–2.48 GHz) and WMTS (1.4–1.43 GHz) for biomedical applications. The proposed antenna is made compatible for implantation by embedding it in a biocompatible Poly Dimethyl Siloxane (PDMS). A study of sensitivity of the antenna performance as a function of the dielectric parameters of the environment in which it is immersed...
In this paper, an automatic detection system of fence completeness for high-speed railway was proposed. This system uses two cameras installed on CIT (Composited Inspection Train) to shoot the fence on each side individually, and then transmit the images by optic fiber to a computer, which processes the images and recognizes the completeness of the fence automatically. The system will recode any loss...
Based on the full understanding of the evaluation index system of Government Information Portal Site in and abroad, this paper inspects the characteristics of Government Information Portal development of local government of all levels in Shanxi and Ningxia Province. Investigating the needs of Government Information Portal Site service by the public, it puts forward a whole new index system of service...
Modern NAND Flash-based Solid-State Drives (SSD) presents low latency, high throughput, low power consumption and solid-state reliability improvements comparing to traditional magnetic-disk based Hard Disk Drives (HDD). However, due to NAND Flash memory cell characteristics, update-in-place is impossible. Instead, the Flash software layer allocates new storage space whenever data is written, even...
According to the characteristics of the information service and the principle of setting the information service evaluation index system, this paper sets up the information service performance evaluation index system including financial indicators, customer satisfaction, the technical innovation ability and the human capital investment based on the thought of the performance evaluation, such as intellectual...
ERP performance evaluation is an important step that helps an enterprise analyzing the contribution of ERP. However this process of assessment itself poses many problems. Therefore more and more enterprises regard the establishment of ERP performance evaluation system as their market competitiveness focus. The paper analyzed the literature of ERP implementation and performance management, established...
With the application of knowledge management (KM) in the enterprises, how to evaluate the implementation effect of knowledge management scientifically and rationally becomes the most concerned issue for entrepreneurs. Knowledge management performance evaluation becomes the most important part in the process of the knowledge management. Based on the performance evaluation system of enterprise knowledge...
In this paper, 40 important factors which inflected the practicing of evaluation information systems was found, that was an obstacle to promote the evaluation software in China today. A four-layer complex system about problems in performance evaluation is created, which involves some tough problems existing in the process of performance evaluation and its information systems in China. Taking the management...
The objective of this study is to construct an balanced scorecard (BSC) based on knowledge management and the fuzzy analytic hierarchy process (FAHP) for evaluating an software companies. The BSC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective...
A major concern of most businesses is their ability to meet customers' performance requirements. Correspondingly, in order to ensure the information system to provide service with high quality, it's necessary to test the performance before information system issued. This paper proposes an approach to performance testing of Index Server, which is developed as ISAPI Extension. This paper mainly focuses...
Traditionally, backup and archiving have been performed on tapes. With the rapid advances in disk storage technology witnessed in recent years, it becomes practical to use disks other than tape libraries as backend storage device for a backup system. For such a disk-based system, storage space efficiency is essential. Since traditional backup method cannot eliminate redundancies during backup, a new...
Fiscal expenditure performance evaluation requires qualitative analysis and evaluation, based on the use of modern econometric and statistical analysis methods. Data envelopment analysis draw the evaluation scores, basing on linear programming bound by the conditions and the objective function, combining with input and output indicators of the object, calculating maximum or minimum of the objective...
Construction Enterprises need to implement ERP projects to constantly improve their competitiveness in the future. However, as having been proved to be an enormously invested and systematically risky project, ERP usually makes construction enterprises fall into "two-difficult" choices. Therefore, a scientific risk evaluation is urgently needed to increase the success rate of ERP project...
Cryptographic devices are recently implemented with different countermeasures against side channel attacks and fault analysis. Moreover, some usual testing techniques, such as scan chains, are not allowed or restricted for security requirements. In this paper, we analyze the impact that error detecting schemes have on the testability of an implementation of the advanced encryption standard, in particular...
The development of an open architecture for multimedia data integration and visualization in template based distributed applications is a challenge for the scientific researches. Because of characteristics of multimedia data, their management and querying techniques are unlike than those of traditional data. We can increase the potential use of multimedia data across various applications by storing...
Software-based self-test (SBST) is increasingly used for testing processor cores embedded in SoCs, mainly because it allows at-speed, low-cost testing, while requiring limited (if any) hardware modifications to the original design. However, the method requires effective techniques for generating suitable test programs and for monitoring the results. In the case of processor core testing, a particularly...
Considering the high packet losses and low, varying bandwidth of GPRS/EDGE network and limited computation power of handheld devices, we present and implement a novel SVC video-on-demand system for hand-held devices over GPRS/EDGE network. For the purpose of handling varying bitrate, we propose a priority based layer switching (PLS) adaptation scheme for SVC stream, which not only performs online...
