Design of Sharp 2D Multiplier-Less Circularly Symmetric FIR Filter Using Harmony Search Algorithm and Frequency Transformation  [PDF]
Manju Manuel, Elizabeth Elias
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.33044
Abstract: In this paper, we present a novel and efficient method for the design of a sharp, two dimensional (2D) wideband, circularly symmetric, FIR filter. First of all, a sharp one dimensional (1D) infinite precision FIR filter is designed using the Frequency Response Masking (FRM) technique. This filter is converted into a multiplier-less filter by representing it in the Canonic Signed Digit (CSD) space. The design of the FRM filter in the CSD space calls for the use of a discrete optimization technique. To this end, a new optimization approach is proposed using a modified Harmony Search Algorithm (HSA). HSA is modified in such a way that, in every exploitation and exploration phase, the candidate solutions turns out to be integers. The 1D FRM multiplier-less filter, is in turn transformed to the 2D equivalent using the recently proposed multiplier-less transformations namely, T1 and T2. These transformations are successful in generating circular contours even for wideband filters. Since multipliers are the most power consuming elements in a 2D filter, the multiplier-less realization calls for reduced power consumption as well as computation time. Significant reduction in the computational complexity and computation time are the highlights of our proposed design technique. Besides, the proposed discrete optimization using modified HSA can be used to solve optimization problems in other engineering disciplines, where the search space consists of integers.

Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.31009
Abstract: In recent years cannabinoids and their derivatives have drawn renewed attention because of their diverse pharmacologic activities. We report here one such case, where all types of medical & psychiatric treatment failed to improve the symptoms; however cannabis use was able to bring back this patient to normal productive & meaningful life. The patient was a 47 year old left handed Caucasian had minor subdural hematoma at the posterior vertex and a minor focal subarachnoid haemorrhage following a physical assault. His impairments included cognitive slowing with decreased short term memory, organized skill & language deficit. His physical disabilities included spastic gait (hemiplegic), VII nerve palsy, mild cerebellar dysfunction, blurred vision and easy fatigue. He was unable to return to work or drive. In addition to cognitive deficit, right hemi paresis & dizziness; he had symptoms of anxiety & depression. Cannabis improved his gait and brought back lots of his memory. Within 6 months all his symptoms abated with use of cannabis and he started to look at cannabis as a real medicine. Slowly he also had improvement in cognitive functions, memory, vocabulary and his gait became increasingly better day by day with continued use of cannabis.
Performance Tradeoff with Routing Protocols for Radio Models in Wireless Sensor Networks  [PDF]
Manju Bala, Lalit Awasthi
Wireless Engineering and Technology (WET) , 2011, DOI: 10.4236/wet.2011.22008
Abstract: In this paper, we have simulated and evaluated the performance tradeoff with routing protocols: Constrained Flooding, the Real-Time Search and the Adaptive Tree on MICA and MICAz platform with different radio models using PROWLER for wireless sensor networks. The simulation results establish that the MICAz motes give low latency, high throughput, high energy consumption, low efficiency but better lifetime while the MICA motes give high success rate and less loss rate. It has been, thus, concluded that in case of all the radio models the MICAz is preferably better than MICA in applications where energy is a constraint. Moreover, use of MICAz motes increases the network lifetime in comparison to MICA for the radio models. Further, the AT protocol can be applied to achieve better energy consumption, efficiency and lifetime in real time for wireless sensor networks.
Assessment of Methane Flux from Municipal Solid Waste (MSW) Landfill Areas of Delhi, India  [PDF]
Manju Rawat, AL Ramanathan
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.24045
Abstract: Carbon dioxide, methane and nitrous oxide are the major Greenhouse Gases (GHG’s), which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. Therefore, there is immense concern for its abatement or utilization from landfill areas. Compared to the west, the composition of municipal solid waste (MSW) in developing countries has higher (40% - 60%) organic waste. This would have potential to emit higher GHG’s from per ton of MSW compared to developed world. Beside that landfills areas in India are not planned or en- gineered generally low lying open areas, where MSW is indiscriminate disposed. This leads to uncontrolled emission of trace gases, foul smell, bird menace, ground and surface water pollution etc. Due to scarcity of land in big cities, mu- nicipal authorities are using same landfill for nearly 10 - 20 years. Hence, the possibility of anaerobic emission of GHG’s further increases. In the present paper we had quantified the methane emission from three MSW landfill areas of Delhi i.e., Gazipur, Bhalswa and Okhla. The results showed that the range of methane emission various in winter from 12.94 to 58.41 and in Summer from 82.69 - 293 mg/m2/h in these landfill areas. The paper has also reviewed the literature on methane emission from India and the status of landfill areas in India.
Conservation of Forestry Biomass with the Use of Alternative Resource  [PDF]
Manju Agarwal, Rachana Pathak
Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.54009
Abstract: The effect of the alternative resource and time delay on conservation of forestry biomass is studied by considering a nonlinear mathematical model. In this paper, interaction between forestry biomass, industrialization pressure, toxicant pressure and technological effort is proposed and analysed. We find out the critical value of delay and observe that there is Hopf bifurcation. Using the normal form theory and the center manifold theorem, we determine the stability and direction of the bifurcating periodic solutions. Numerical simulations are given to illustrate the analytical results.
Mathematical Modeling and Analysis of Tumor Therapy with Oncolytic Virus  [PDF]
Manju Agarwal, Archana S. Bhadauria
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.21015
Abstract: In this paper, we have proposed and analyzed a nonlinear mathematical model for the study of interaction between tumor cells and oncolytic viruses. The model is analyzed using stability theory of differential equa- tions. Positive equilibrium points of the system are investigated and their stability analysis is carried out. Moreover, the numerical simulation of the proposed model is also performed by using fourth order Runge- Kutta method which supports the theoretical findings. It is found that both infected and uninfected tumor cells and hence tumor load can be eliminated with time, and complete recovery is possible because of virus therapy, if certain conditions are satisfied. It is further found that the system appears to exhibit periodic limit cycles and chaotic attractors for some ranges of the system parameters.

Manju Sanghi
International Journal of Information and Network Security (IJINS) , 2012, DOI: 10.11591/ijins.v1i1.249
Abstract: In 2007, Lu and Cao proposed a simple three party password authenticated key exchange (S-3PAKE) protocol. In 2008, Guo et al. have shown that S-3PAKE protocol is completely insecure against man-in-the-middle attack and undetectable on-line password guessing attack. They also provided an improved protocol (G-3PAKE) that addresses the identified security problems. Recently, Choi and Yoon have demonstrated that G-3PAKE protocol still falls prey to undetectable on-line password guessing attack by any other client. In the present paper we propose an improved G-3PAKE protocol which can resist all the known attacks along with its formal proof.
