Strong and efficient Army of any country play a vital role in today's modern and scientific world. Soldiers are crucial to build a strong army. In developed countries, for the health monitoring purpose of army personal, a number of gadgets or devices are attached with them to take the look on their healthiness and their ammunitions. Health relating sensors like heartbeat sensor, body temperature measuring sensor, processing capabilities and transmission, can thus help to make economic wearable gadgets for monitoring of health. Different techniques and algorithms are used to pin-point the exact location of the soldier. In this paper we are going to design a smart device for soldier using modern technologies and techniques. This device would be carried by soldier in warfare. The device will be able to sense heart beat and body temperature of soldier and transmit the reading on base station where the cumulative data will be displayed. A small database is organized for storage of readings. Solder can also sent a secret massage on base station. In order to make the reading accurate and precise a formula is designed which is a correlation of body temperature and heartbeat. The health condition of solider is going to predict in our work furthermore the base station can also send the answer of secret code. This system is particularly purposed for Pakistani soldiers who are fighting against the terrorism. © 2016 IEEE.

Stemming reduces numerous variant forms of a word to its base, stem or root form which is essential for different language processing applications including Urdu IR. Urdu is a resource poor and morphologically rich language. Multilingual Urdu vocabulary is very challenging to process due to its complex morphology. Research of Urdu stemming has an age of a decade. However, there has not been any work reported on dictionary based Urdu stemming. The present work introduces a dictionary based Urdu stemmer with improved performance as compared to the existing Urdu stemmers. The significance of the study is the identification of dictionary-based approach for Urdu stemming as the most promising approach, especially with dictionary update feature. Testing shows 94.85% overall accuracy on test data and results can be further improved by cleaning test data and dictionary updates. © 2005 - Ongoing JATIT & LLS.

This paper studies the local adaptive and robust adaptive control methodologies for the synchronization of the chaotic drive and the response systems with finite time lags, bounded delay rates, unknown parameters, and perturbations. A local adaptive coherence control condition under bounded initial condition is developed to synthesize a feedback controller capable of executing successful synchronization of the drive and the response systems with uncertain parameters and delay belonging to a range (with either zero or nonzero lower bound). A sufficiency condition for the adaptive control approach is inculcated through an amendment in the conventional Lyapunov–Krasovskii functional, which enables to develop the adaptation laws for the unknown parameters associated with the nonlinearity in the dynamical behavior of the drive and the response systems. Further, a robust adaptive synchronization control condition for asymptotic convergent behavior of the synchronization error to a bounded region under perturbations as well as disturbances is provided. Indifferent to the existing works, delay-range-dependent adaptive synchronization methodologies are derived in this paper, and the rendered controller design conditions are valid for both the slow and the fast variations in time delays. Numerical simulations for the chaotic delayed Hopfield neural networks are presented to elaborate the efficacy of the proposed delay-range-dependent adaptive and robust adaptive synchronization control methodologies. © 2017 Springer Science+Business Media Dordrecht

Fast pyrolysis is one of the prospective techniques employed to get energy and valuable chemicals from biomass. The yield and composition of pyrolysis products depend on the characteristics of feedstock and process operating parameters. A lab scale pyrolysis system consists of bubbling fluidized bed reactor (capacity 2kg/hr) is being designed. Effect of particle size and operating temperature on the fast pyrolysis of Pakistani maize stalk has been investigated. Experimentation was done with the temperature range of 360-540°C and particle size of 1-2 mm (SMD). Both parameters are found to have significant effect on the yield and characteristics of bio oil produced under the bubbling fluidized bed conditions. Bio oil yield increased with the increase of temperature followed by a decreasing trend. Maximum yield (41 wt. %) of bio oil was obtained at 540°C with particle size of around 1.0 mm. High temperatures resulted in high ratios of char and gas. GC-MS analysis of bio oil identified the large number of compounds including butanal, 2,3-Butanedione, Benzene, 1-Butanol, Acetic Acid, 3-Pentanone, Acetol, Toluene, 2-Butenal, 2-methyl-methyl pyruvate, Propanoic acid, Ethylbenzene, p-Xylene, Cyclopentanone, 2-methyl-o-xylene, 2-Butanone, 4-hydroxy-Furfural, 2-Furanmethanol, Benzene, 1,2,3-trimethyl-1-Heptanol, Benzaldehyde, 4-methyl-phenol, guaiacol, o-cresol, Naphthalene, Phenol, 2-methoxy-4-methyl-phenol, 2,4-dimethyl-phenol, 4-ethyl-naphthalene, 2-methyl-2-Furancarboxaldehyde, 5-(hydroxymethyl)-syringol, Vanillin, Ethanone,1-(4-hydroxy-3-methoxyphenyl), 3',5'-Dimethoxyacetophenone, 2-Propanone, 1-(4-hydroxy-3-methoxyphenyl), 4-Hydroxy-2-methylacetophenone, 4-Hydroxy-3-methylacetophenone, Levoglucosan, syringaldehyde, Ethanone, 1-(4-hydroxy-3,5-dimethoxyphenyl). Gas Chromatography analysis of non-condensable gases produced from the fast pyrolysis process is also being done and discussed.

Characterization is important to measure the potential of biomass for its utilization in combustion or pyrolysis processes. Characterization study is carried out for cotton and maize stalk samples collected from the provinces of Punjab and Sindh, Pakistan. The proximate, ultimate and thermo-gravimetric analysis (TGA) are performed. TGA is done in inert atmosphere at four heating rates i.e. 5, 10, 15, 20°C/ min. Residual weight is a function of heating rate and increases with heating rate. Higher residual weight is obtained for cotton stalk at different heating rates from 5 to 20°C/min. The values of energy of activation for cotton and maize stalk are 35 and 40 kJ/mol respectively which is calculated using isothermal conversion method assuming first order kinetics.

Background: Protein structural alignment is one of the most fundamental and crucial areas of research in the domain of computational structural biology. Comparison of a protein structure with known structures helps to classify it as a new or belonging to a known group of proteins. This, in turn, is useful to determine the function of protein, its evolutionary relationship with other protein molecules and grasping principles underlying protein architecture and folding. Results: A large number of protein structure alignment methods are available. Each protein structure alignment tool has its own strengths andweaknesses that need to be highlighted.We compared and presented results of six most popular and publically available servers for protein structure comparison. These web-based servers were compared with the respect to functionality (features provided by these servers) and accuracy (how well the structural comparison is performed). The CATH was used as a reference. The results showed that overall CE was top performer. DALI and PhyreStorm showed similar results whereas PDBeFold showed the lowest performance. In case of few secondary structural elements, CE, DALI and PhyreStorm gave 100% success rate. Conclusion: Overall none of the structural alignment servers showed 100% success rate. Studies of overall performance, effect of mainly alpha and effect of mainly beta showed consistent performance. CE, DALI, FatCat and PhyreStorm showed more than 90% success rate. © 2016 Pontificia Universidad Católica de Valparaíso. Production and hosting by Elsevier B.V. All rights reserved.

Pyrolysis behavior of low grade Pakistani coals was done using thermo gravimetric analyzer or TGA. The effect of changing the rate of heating was analyzed at for the pyrolysis process. The particle size was also varied and its effect was also investigated. Kinetic parameters were determined for different heating rates. This research also investigated the combustion behavior of low grade coals, from Balochistan like Duki and Chamalung, in a Circulating Fluidized Bed (CFB) riser. This is perhaps the first local practical experience of evaluating combustion performance of local coal blends in a CFB. The effects of varying the primary air and feed rate on emissions were analyzed. The experiments were carried out in a hot CFB installed at NFC-IET, Multan. The experiments showed that the temperature rose to about 900°C at the top of the CFB in quick time. The temperature dependence on combustion and emission were also identified.

Grains are the economical part of maize that demand proper management practices to achieve the crop potential. This study explored the influence of different tillage practices and poultry manure levels on the grain length, breadth, area, grains weight per cob and grain yield per m2of spring planted maize. The experiment was set up using Randomized Complete Block Design (RCBD) with split plot arrangement having four tillage practices as main plot treatments; zero tillage, minimum tillage, conventional tillage and deep tillage. Sub plot treatments were three poultry manure levels; control (no poultry manure), poultry manure @ 5 Mg ha-1 and poultry manure @ 10 Mg ha-1. Data indicated that the deep tillage practice significantly improved (p>0.05) the length, breath and area of maize grains over the other tillage practices in both years of study. Significantly higher grain yield was produced in deep tillage practice as compared to conventional, minimum and zero tillage practices. Increasing order of poultry manure dose treatments produced the bold and healthy seeds over the control treatment. A positive correlation between grain yield per m2 vs physical properties of maize grain and grains weight per cob was recorded. The study concludes that the productive effect of integrated use of poultry manure and chemical fertilizers application on the maize grain yield.

We focus on Cyclostationary spectrum sensing technique in order to increase the spectrum efficiency which will become essential for cognitive radios. Static allocation of the frequency spectrum does not meet the growing demands of current wireless technology that's why spectrum sensing and dynamic allocation will become indispensible part of future wireless networks. Cognitive radio can sense the spectrum and detect the idle frequency bands which are allocated to primary users, if not; secondary users can be allocated unoccupied frequency bands in order to avoid any interference. Our primary goal is to develop efficient way of sensing holes for orthogonal frequency division multiplexing (OFDM) systems for spectrum sharing regimes. Using Cyclostationary features we are able to detect primary user. Here Cyclostationary features for primary user detection are exploited through AWGN communication channel with various noise levels. We have considered an OFDM system and exploited its parameters to examine how it relates to primary user detection and its detection probability with various different noise levels is calculated. © 2011 IEEE.
