Coverage Issues in Wireless Ad-Hoc Sensor Networks

Wireless Ad-Hoc sensor networks have a broad range of applications in the military,vigilance, environment monitoring, and healthcare fields. Coverage of the sensor networks describes how well an area is monitored. The coverage problem has been studied extensively, especially when combined with connectivity and well-organized. Coverage is a typical problem in the wireless sensor networks to fulfil issued sensing tasks. In general, sensing analysis represents how well an area is monitored by sensors. The quality of the sensor network can be reflected by levels of coverage and connectivity that it offers. The coverage issues have been studied extensively, especially when combined with connectivity and energy efficiency. Constructing a connected fully covered, and energy efficient sensor network is valuable for real world applications due to limited resources of sensor nodes. The survey recent contributions addressing energy efficient coverage problems in the context of static WASNs, networks in which sensor nodes do not move once they are deployed and present in some detail of the algorithms, assumptions, and results.

Nanostructured mesoporous carbon as electrodes for supercapacitors

Symmetrical carbon/carbon double layer capacitors (EDLCs) were fabricated employing nanostructured mesoporous nongraphitized carbon black (NMCB) powders and their EDLC behavior was studied using electrochemical techniques viz., cyclic voltammetry, a.c.-impedance, and constant current cycling. Rectangular shape cyclic characteristics were observed indicating the double layer behavior of the NMCB carbon electrodes. The mechanism of double layer formation and frequency dependent capacitance were deduced from the ac-impedance analysis. Specific capacitance, power density and energy density were derived from constant current charge/discharge measurements. NMCB powders demonstrated a specific capacitance of about ∼39 F g−1 and the power density of 782 W kg−1 at a current density of 32 mA cm−2. Nevertheless, at a low current density (3 mA cm−2), the specific capacitance of ∼44 F g−1 was achieved, which corroborates with the values obtained by means of ac-impedance (40 F g−1) and cyclic voltammetry (41.5 F g−1). The test cells demonstrated the stable cycle performance over several hundreds of cycles

A Microbiological study on the aetiological agents of acute meningitis and meningoencephalitis in a tertiary care hospital

BACKGROUND: Acute central nervous system infections are medical emergencies requiring immediate diagnosis and treatment. As the clinical manifestations cannot always be relied upon, rapid and reliable diagnostic methods are of utmost importance for prompt initiation of therapy. Acute meningitis/meningoencephalitis is an important cause of mortality and long term neurological sequelae worldwide. Despite the availability of potent newer antibiotic therapy, the mortality rate remains significantly high in India and other developing countries. AIM & OBJECTIVES: The objective of this study was to determine the distribution of acute meningitis/meningoencephalitis and its aetiological agents among adults admitted in a tertiary care hospital. METHODS: A total of 100 patients >18years of age with signs and symptoms of acute meningitis/meningoencephalitis were included in the study. Cerebrospinal fluid (CSF) was collected and sent to the laboratory for cytological and biochemical analysis. CSF was subjected to Gram stain and latex agglutination test to detect capsular antigens of common bacterial pathogens. Bacterial and fungal culture were performed by standard microbiological methods. Serum and cerebrospinal fluid (CSF) were tested for the presence of IgM antibodies against viruses like Japanese encephalitis virus (JEV), Dengue virus (DENV), Herpes simplex virus (HSV) and Varicella zoster virus (VZV). RESULTS: A total of 31 aetiological agents were identified in 29 (29%) clinically suspected cases with two patients having dual infection. Of the aetiological agents identified, viruses (23%) were the predominant pathogen followed by bacteria (6%) and fungi (2%). 23 viral agents were identified from 21 patients with two patients having dual infection (JEV & DENV and JEV & HSV). Bacterial causative agents included Streptococcus pneumoniae (n = 2), Escherichia coli (n = 1), Klebsiella pneumoniae (n=2) and Pseudomonas aeruginosa (n=1). From both the patients with fungal meningitis/meningoencephalitis, Cryptococcus neoformans was isolated. CONCLUSION: Viruses were found to be the common cause of acute meningitis/meningoencephalitis than bacterial agents among the study population in the present study. Gram negative bacilli were found to be more frequently isolated from the patients included in this study. Established organisms of meningitis such as Haemophilus influenzae and Neisseria meningitidis were not isolated in this study. As early diagnosis is crucial in disease treatment, the need of point of care test is recommended
