This paper presents the development of an intelligent portable human recognition and location identification system using ARM7 based microcontroller, OpenCV based machine and advanced communication technologies like GPS and GSM. With the development of video surveillance gradually from the traditional security surveillance to intelligent surveillance, we present a method, to process the image a...

In recent years, survival rate from myocardial infarction and bundle branch block has been increased due to the advancements in medical field. Continuous monitoring and location management of these patients becomes an essential task. Hence this study aims in design and development of GPS in a Field Programmable Gate Array (FPGA) and interfaced with a GSM modem to transmit the location of a civi...

Wireless Sensor Networks (WISENETs) support variety of collaborative applications such as monitoring, tracking and surveillance. Different applications demands different granularity of location information. Thus, localization is really become an important challenge in wireless sensor networks. Although, many localization techniques [2, 3, 4, 5, 11, 10] have been developed, but all of them have ...

Localization in mobile ad hoc networks (MANETs) is the process of fixing the position of a node according to some real or virtual coordinate system. In many cases, solutions like Global Positioning System (GPS) are not feasible. As a result, several algorithms have been developed for localization based purely on local communication. However, many of these suffer from one of the following: flood...

In this paper, we propose an efficient acquisition scheme for GPS receivers. It is shown that GPS signals can be effectively sampled and detected using a bank of randomized correlators with much fewer chip-matched filters than those used in existing GPS signal acquisition algorithms. The latter use correlations with all possible shifted replicas of the satellite-specific C/A code and an exhaust...

The Global Positioning System (GPS), Inertial Navigation System (INS) and Pseudolite (PL) technologies all play very important roles in navigation systems. As an independent navigation system, GPS can provide high precision positioning results which are independent of time. However, the performance will become unreliable when the system experiences high dynamics, or when the receiver is exposed...

Sialic acids as terminal residues of oligosaccharide chains play crucial roles in several cellular recognition events. Exploiting the selective affinity of Achatinin-H toward N-acetyl-9-O-acetylneuraminic acid-alpha2-6-GalNAc, we have demonstrated the presence of 9-O-acetylated sialoglycoproteins (Neu5,9Ac(2)-GPs) on lymphoblasts of 70 children with acute lymphoblastic leukemia (ALL) and on leu...

BACKGROUND Early identification of permanent hearing impairment in children enables appropriate intervention which reduces adverse developmental outcomes. The UK Government has introduced a universal hearing screening programme for neonates. All involved health professionals, including those in Primary Care, need to be aware of the service to enable them to offer appropriate support to their pa...

The objectives of this study were to investigate the awareness, motivation, and readiness of medical staff to take part in a cervical cancer screening program (CSP), with the ultimate aim of increasing the response rate to invitation letters and improving CSP effectiveness and coverage. Certified gynecologists (GYNs) and general practitioners (GPs) practicing in the national and private healthc...
