In this work, we strive for three particular polynomials with integer coefficients that may be expanded by non-zero values to the position where the product of any two numbers is a perfect square.

In this paper, we seek for three specific polynomials with integer coefficients to such an extent that the product of any two numbers expanded by a non-zero number (or polynomials with integer coefficients) is a perfect square.

Stream processing is usually done either on a tuple-by-tuple basis or in micro-batches. There are many applications where tuples over a predefined duration/window must be processed within certain deadlines. Processing such queries using stream processing engines can be very inefficient since there is often a significant overhead per tuple or micro-batch. The cost of computation can be significantly reduced by using the wider window available for computation. In this work, we present scheduling schemes where the overhead cost is minimized while meeting the query deadline constraints. For such queries, since the result is needed only at the deadline, tuples can be processed in larger batches, instead of using micro-batches. We present scheduling schemes for single and multi query scenarios. The proposed scheduling algorithms have been implemented as a Custom Query Scheduler, on top of Apache Spark. Our performance study with TPC-H data, under single and multi query modes, shows orders of magnitude improvement as compared to naively using Spark streaming.

A winning personality is the physical attribute of a person and is considered as his or her success in personal, academic, and professional careers. However, in the ESL context, most engineering students seem to be unaware of the need for and importance of an appealing personality for achieving success in both personal and professional careers. Although students are given a short-term training in soft-skills by their respective college or institute, engineering students seem to lack aspects of a pleasing personality which helps them in job placements and later in the work environment. Therefore, the main aim of this study is to understand and build engineering students’ personality traits such as enthusiasm, dependability, and teamwork for a successful career. For this purpose, to understand the students’ personality types, 25 engineering students were administered a pre-test based on Carl Jung and Isabel Briggs Myers’ typological approach to personality. Students were helped in building personality through the soft-skills training. The data was analyzed and interpreted both qualitatively and quantitatively. The results indicated that having a pleasing personality and exhibiting soft-skills enables in building students’ individual personality for employment readiness. Implications were offered to students, placement trainers, and teachers. It is concluded that having a charming personality will support students in landing their desired jobs.

The potato cyst nematodes are the most wilful and difficult to manage pests of potato crop. Due to the regulatory considerations and potential risk involved in environmental and health hazards, the options for controlling this nematode are becoming increasingly limited. Among the available management options, trap and antagonistic crops offer viable alternative for controlling PCN species. Therefore the present experiments were conducted to determine the effect of locally available nematode trap crop, Solanum sisymbriifolium and antagonistic crops against potato cyst nematodes. Initially, S. sisymbriifolium was evaluated for its trap crop potential against PCN and the results showed that S. sisymbriifolium acts as a resistant crop for both the species of PCN, as no females were observed on the roots of the trap crop up to the end of the crop season. In addition to this, in the subsequent season negligible populations of PCN females with improved plant growth parameters were observed in susceptible potato cv. Kufri Jyoti. In another experiment, its efficiency was compared with antagonistic crop species viz., Tagetes patula (marigold), Allium sativum (garlic) and Brassica juncea (mustard) on the population decline of PCN. From the study, it was observed that minimum populations of both the species of PCN (0.6 and 33.4 female's plant−1 respectively) were supported in two succeeding seasons of susceptible potato cultivar where S. sisymbriifolium was grown in the preceding season which was followed by marigold, garlic and mustard-based sequences. Therefore, S. sisymbriifolium can be used as a potential trap crop for the management of PCN; however, future studies on its suitability in field conditions are required for its effective utilization under field condition for the management of this nematode.

In this communication, we accomplish special Diophantine triples comprising of square pyramidal numbers such that the product of any two members of the set added by their sum and increased by a polynomial with integer coefficient is a perfect square.

The detailed micro-Raman study of pure TiO2 and Si-doped TiO2 thin film was synthesized by facile dip-coating technique for photocatalytic application, to degrade the organic species in polluted surface water due to the recent environmental crisis by dye industries. The prepared pure TiO2 and Si-doped TiO2 thin film were annealed at various temperatures 300 °C and 450 °C. Micro-Raman spectrum of TiO2 nanostructure confirms the presence of anatase phase. The crystallinity of TiO2 and uniformity of the film were improved in annealing temperature of 450 °C. The particle size of TiO2 was calculated on the basis of the phonon confinement model with the theoretical phonon dispersion relation. The phonon confinement effect depends upon the blue shift and broadening of the lower-frequency Eg Raman mode of TiO2. Also, the compressive stress of TiO2 was evaluated using a suitable formula. In addition, the dye degradation activity under visible light irradiation process using methylene blue (MB) was analyzed to check the ability of photocatalytic activity of prepared samples, in which, the fast MB degradation kinetics achieved by Si-TiO2 nanocrystal and it degrades 99% of MB within 60 min. Also, it exhibits more than 90% photodegradation efficiency up to ten recycle than pristine. Moreover, the possible photocatalytic mechanism of the prepared system was discussed.

In this chapter, the binary quadratic equation x2 - 2xy - y2 + 2x + 14y = 72 represents a hyperbola is analyzed for its non-zero distinct integer solutions. Also, we obtain a sequence of its integral solutions and present a few interesting relations among them. The recurrence relations satisfied by the solutions x and y are obtained.

Background: Large ruminants are considered as high risk anaesthesia patient for abdominal surgery because of their heavy weight, the late-term gravidity and the expected long duration of anaesthesia. In order to augment cardiopulmonary function, we aimed at decreasing the requirement of inhalant agents for surgery. Several studies have revealed that lignocaine infusion significantly reduces the minimum alveolar concentration (MAC) of inhalation agents in a variety of species. Thus the present study is focused on assessing the adjunct property of intravenous lignocaine CRI in multimodal general anaesthetic protocol employed for intestinal surgery in cattle. Methods: The study was carried out in 12 clinical cases of cattle which were randomly categorized into two equally groups. All the animals were premedicated with dexmedetomidine and butorphanol tartrate at the dose rate of 0.5 µg per kg and 0.02 mg per kg body weight i.v. respectively. After five minutes of premedication, induction of anaesthesia was achieved with double drip solution containing ketamine hydrochloride 2 mg and guaifenesin 50 mg per mL respectively, administered i.v. “to effect”. Anaesthesia was maintained with isoflurane in all the animals. In group II animals ten minutes prior to skin incision, slow intravenous lignocaine bolus at the dose rate of 2 mg per kg and continuous rate infusion at the dose rate of 50 µg per kg per min was delivered through volumetric infusion pump. Result: The Isoflurane liquid utilised for maintenance decreased significantly in group II than group I, which signifies that the inclusion of lignocaine in the anaesthetic protocol has 14.95 per cent isoflurane sparing effect.

The beneficial effects of two probiotic bacterial strains Marinilactibacillus piezotolerans and Novosphingobium sp. during the culture of Indian white shrimp, Penaeus indicus, under biofloc and clear water system were evaluated. The experimental variation were CW1 (M. piezotolerans in clear water), BFT1 (biofloc + M. piezotolerans), CW2 (Novosphingobium sp. in clear water), BFT2 (biofloc + Novosphingobium sp.) and control (without bacterial strains and biofloc). Growth and survival considerably increased in probiotic bio-augmented treatments. Probiotic incorporation significantly improved water quality, especially ammonia reduction. Microbiota analysis from gut samples taken from different treatments revealed varied microbial population structure among clear water culture, biofloc culture and control. Proteobacteria and Firmicutes were the top phyla observed in the treatments which were significantly higher in bio-augmented systems than the control. Vibrio genera were predominantly observed in control and clear water system compared to that of biofloc systems. Immune genes were significantly altered in response to probiotic gut microbial supplementation than the control. Higher gene expression profile of important immune genes was observed in the biofloc reared shrimps. Expression of digestive enzyme related genes such as trypsin, chymotrypsin, cathepsin L, cathepsin B and alpha amylase were also upregulated significantly in probiotic supplementation especially in the biofloc treatments. Proteomic analysis of hepatopancreas of shrimps from different treatments was carried out by using 2D gel electrophoresis and MALDI-TOF analysis. The proteins were mostly related to growth and stress tolerance. Eukaryotic initiation factor 4E binding protein was expressed in all the groups and it was high in biofloc treated animals followed by animals treated solely with probiotics compared to those of control groups. The results concludes that biofloc already proved as an effective culture method for healthy shrimp production and supplementation of probiotic bacterial strains registered additional benefit for growth, survival, microbial, immunological status of P, indicus culture.

A130-day culture experiment was performed to compare the effects of rearing Litopenaeus vannamei in a biofloc system and conventional autotrophic system, supplemented with diets having graded protein levels on growth performance, non-specific immune response and immunomodulatory activity. The experiment groups consisted of four protein-level treatments with four replicates each, and was performed in 16 experimental units (7.5-Tcapacity) stocked with juvenile L. vannamei (initial average weight 1.48 ± 0.4 g) at a density of 150 juvenile shrimps /m3. Biofloc-based groups fed with supplementary feed containing varying levels of crude protein (CP) BFT40 (40% CP), BFT32 (32% CP) and BFT24 (24% CP), and a control group (CP 40%), were maintained in an autotrophic system. At the end of the experimental period, there was an improvement of 32.6–52.6% in terms of productivity, 22–27.6% average body weight; 8.7–19.6% survival rate and 10–31% feed conversion ratio (FCR) in shrimp maintained in biofloc systems as compared to control. Similarly, the protein efficiency ratio (PER) in biofloc treatment groups was32 to 83% higher than control. The shrimp also showed higher resistance to disease in the biofloc treatment when challenged with pathogenic Vibrio parahaemolyticus, as survival of juveniles was significantly higher (p

This study aims to evaluate the influence of different carbohydrate sources on water quality, growth performance and immunomodulation in pacific white shrimp and to find an alternate for molasses in biofloc system. The experiment consists of 8 biofloc treatments with different carbon sources, C1 (maida flour), C2 (wheat flour), C3 (gram flour), C4 (millet flour), C5 (rice flour), C6 (corn flour), C7 (molasses), C8 (multigrain flour) and un-supplemented control C0 was conducted in 200 L tank system for 120 days. Shrimp juveniles of average weight 1 g were stocked at the rate of 300 nos/m3. Shrimp reared in C8, C7 and C4 treatments had similar growth, survival rate, and disease resistance and were significantly higher (P

In today’s world, brain tumor is detected in many people. The count of people affected with brain tumor, increases every day, irrespective of age and gender. The survival rates of brain tumor is very less when compared to other tumor cells. Brain tumor is the abundant growth of thick and unusual cells in brain. Brain tumor perhaps can be malignant tumor or benign. Malignant tumors aggressively spread to distant part of the body. Tumor that does not spread nearby tissue called as benign. Detection of brain tumor using various technologies is still under research. Brain tumor identification and segmentation in recent years is done by Magnetic Resonance Imaging (MRI). Software for accurate identification of brain tumor is still under existence. So, we propose an idea for identification and segmentation of brain tumor using deep learning. The first step will be processing the Magnetic Resonance Imaging (MRI) by giving it as the input, it is analyzed and segmented using various deep learning techniques such as initializing the CNN, pooling, flattening, compiling the CNN using Tensor Flow as backend. Thus, Identification and segmentation of brain tumor can be identified easily and efficiently.

A 60 days nursery-based co-culture of Indian white shrimp, Penaeus indicus along with seaweed, Gracilaria tenuistipitata trial was carried out in Recirculatory Aquaculture System (RAS) of 6000 Liters capacity tank (FRP, reinforced fibre plastics) by using biofloc technology (BFT) to evaluate the growth, survival performance and immune potential. Accordingly a completely randomized experiment was designed with six treatments. These treatments were: T1- Static system (Control), T2 - RAS with BFT, T3 - RAS with Gracilaria, T4 - RAS and BFT customized with bacterial consortium, T5 - RAS with BFT + Gracilaria + bacterial consortium, T6 - Static + Gracilaria + BFT (without consortium and without RAS). Shrimp post larvae (0.08 ± 0.03 g) were stocked at a density of 3000 nos./ton. RAS with BFT along with the seaweed and bacterial consortium showed significantly higher growth and survival compared to control (T1) and treatments without BFT (T3). The control (T1) exhibited significantly lower growth, weight gain, specific growth rate, yield and higher FCR value than that of the RAS + BFT (T2), RAS+ seaweed (T3) and RAS + BFT or their combinations with bacterial consortium (T4 and T5). The treatment having seaweed without BFT (T3) showed higher survival than the static control (T1), but no significant difference in growth. The highest ABW of 4.23 ± 0.39 was obtained in T4 (BFT customized with consortium) followed by T5 (BFT + seaweed + bacterial consortium) and lowest was observed in T1 (2.14 ± 0.4). Similarly, the highest survival (92.33 ± 1.52) and production (10.39 ± 0.24 kg/ton) was observed in T5. Significantly higher NH4-N and NO2-N was accumulated in the control (T1) in comparison with other treatment like T4 and T5. Immune parameters viz., PPO activity, Total Serum Protein and Total Hemocyte Count (THC) showed significantly higher values in all the treatments compared to control. This study establishes the novel concept of incorporation of macroalgae in biofloc based RAS improving the production performance and immune response of shrimp during nursery as well as grow-out phase.

Subject columns are the important columns that help infer the correct subject matter of the table. The main challenging problem is detecting appropriate subject columns in tables with more than the same. Existing approaches restricted to identification of only one subject column in tables with more than one subject column. With this, it is not possible to infer the correct subject matter of the table. In case of subject column detection, the existing approaches requires table information such as table headers, additional evidences about the table from web pages and also training in prior with a labeled set of tables. To solve these issues, in this paper, we proposed a simple header independent semantic based Concept-Voting Subject Column Detection (CVSCD) algorithm. The proposed algorithm identifies possible subject columns in table with more than one subject column, which provides a way to infer table’s correct subject matter. Moreover, CVSCD is unsupervised and works for tables without any table information such as table caption, table headers etc. Experimental results have shown that our approach achieved better accuracy compared to the existing approaches on a corpus of tables extracted from web.

In this research effect of tin on pure magnesium based on the various mechanical, electrical and thermal properties were investigated and analysed based on certain effective mathematical models already established. The models exploited in this work involve Voigt, Reuss method from Rule of Mixture, Paul method, Maxwell method and P.G. Klemens method. The tensile strength and density values were found increasing with respect to the increment in the alloying percentage of tin while the yield strength decreased. However, any of the developed models was found not to be efficient to provide the values for electrical conductivity during validation.

In this paper, we construct a sequence of Special Dio 3-tuples for centered square numbers involving half companion sequences under 3 cases with the properties D(-2), D(-11) & D(-26).

The study was carried out in 12 clinical cases of cattle to assess the cardiovascular effects of intravenous continuous rate infusion of lignocaine as an adjunct to general anaesthesia for intestinal surgeries. The animals were indiscriminately selected and categorized equally into two groups. All the animals were premedicated with dexmedetomidine and butorphanol tartrate at the dose rate of 0.5 µg per kg and 20 µg per kg body weight i.v. respectively. After five minutes of premedication, induction of anaesthesia was achieved with double drip solution containing ketamine hydrochloride 2 mg and guaifenesin 50 mg per mL respectively, administered i.v. “to effect”. Anaesthesia was maintained with isoflurane in all the animals. In group II animals ten minutes prior to skin incision, slow intravenous lignocaine bolus at the dose rate of 2 mg per kg and continuous rate infusion at the dose rate of 50 µg per kg per min was delivered through volumetric infusion pump. There was no significant difference in cardiovascular parameters noticed between the group which signifies that intravenous lignocaine at this dose in anaesthetised cattle is cardiovascular dynamic.

Two sets of experimental trials (45 days each) were carried out to optimize protein requirement and stocking densities of Indian white shrimp, Penaeus indicus post-larvae in nursery rearing. In experiment 1, the effect of varying dietary protein levels (30, 40, 50, and 60%) on the growth performance of nursery reared P. indicus (PL12) was evaluated. The experiment 2 had 3 × 3 factorial design with three levels of stocking density (1650, 3350, 8350 PL m−3) and three management systems; zero water exchange (ZWE), ZWE with soil base (ZWE + SN), and ZWE with soil base and substrate integration (ZWE + SN + SUB) resulting in nine treatments. Experiment 2 was followed by a 21-day growth trial in low volume floating cages to estimate the compensatory growth performance. In Exp I, shrimp fed with 30% dietary protein recorded on par (p > 0.05) growth (0.39 ± 0.02 g) and survival (89.13 ± 5.04%) compared to higher protein fed shrimps (ABW: 0.39–0.44 g and 86–93% survival). In experiment 2, both the stocking density and management system had a significant effect (p 0.05). However, a density-dependent growth reduction (p

Effect of bio-augmentation of Bacillus spp in biofloc on growth, survival and immunity in Indian white shrimp Penaeus indicus was evaluated. Nine Bacillus strains were isolated and screened individually as well as in the form of a consortia. To maintain a C:N ratio of 12:1 a blend of carbohydrate sources was used. Bio-augmentation with bacterial consortium and Virgibacillus sp. produced improved growth and immunity. Shrimp survival ranged from 80 to 95% among treatments. Production was higher (35%) in the biofloc tanks with an average body weight (ABW) of 10.89 ± 1.2 g. On evaluating the immune responses, it was found that trypsin significantly (P 0.05) enhanced Prophenoloxidase (PO) activity in Lysinibacillus, Bacillus cereus, Bacillus licheniformis and Bacillus subtilis bio-augmented groups. Laminarin induced PO activity was observed in groups supplemented with Oceanobacillus sp., Bacillus sp.and Bacillus megaterium. The lysozyme (LZ) activity was significantly (P 0.05) higher in B. cereus and Microbial Consortia (MC), while other treatments were less effective. Total hemocyte count (THC) significantly (P 0.05) increased in all treatment groups compared to the control. Hyaline hemocyte (HH) count was significantly (P 0.05) higher in the control group (14.43%). Semi granular hemocytes (SGH) was higher in groups treated with Lysinibacillus, Bacillus sp., B. licheniformis and B. subtilis. The granular hemocyte (GH) count was significantly (P 0.05) higher in Virgibacillus sp., B. cereus, B.megaterium and Oceanobacillus sp. The biofloc alone (BF), treated and augmented with B. megaterium significantly (P 0.05) increased phagocytic activity. Highly significant phagocytic index (PI) was observed in bio-augmented groups, BF and MC. The relative expression levels of immune genes were found to be significantly up-regulated in shrimps grown in bio-augmented groups. Enhanced immunological parameters implies that bio-augmentation of biofloc with Bacillus spp. improved immunity in shrimps. Hence, bio-augmentation of probiotics in biofloc may be useful in improving culture conditions to produce P. indicus.

This paper mainly focuses on the accurate estimation of speeds ranging from very low speed to rated speed to control sensorless Direct Torque Controlled (DTC) Induction Motor Drives (IMD). Extended Kalman Filter (EKF) is used to estimate the speed from the noisy data based on state space method and recursive algorithm. Previous studies suggest the development of a new state space model for estimation in EKF, with load torque as an input variable and not as an estimated quantity. In order to eliminate the dependency on load torque, this paper projects the derivation of a novel adaptive speed adjustment equation and its use for speed estimation in EKF. The new state space model developed is validated using MATLAB-Simulink platform for speeds ranging from low speed to rated speed at rated torque and various other torque conditions.

Waste management has become a serious issue, especially in developing countries with very high population. Lack of bins or proper disposal facilities remains a problem to date. Various governments are also trying hard to push for a cleaner nation by helping curb pollution and improving public sanitation. The smart bin is an important and significant application to deliver cleanliness. A smart bin with automated metal and non-metal segregator is modeled. Using NodeMCU, the level of the bin is monitored in real time and sent to the cloud for further analysis. A novel mathematical model to calculate the most optimal way of distributing the bins in one dimension has also been discussed. Tourist areas, parks, educational institutions, etc., can use the bins in a network to improve sanitation.

The major role of electronics device is to provide low power dissipation and compact area with high speed performance. Among the major modules in digital building blocks system, multiplier is the most complex one and main source of power dissipation. Approximate Computing to multiplier design plays major role in electronic applications, like multimedia by providing fastest result even though it possesses low reliability. In this paper, a design approach of 16bit Wallace Tree approximate multiplier with 15-4 compressor is considered to provide more reliability. The 16×16 Wallace tree multiplier is synthesized and simulated using Xilinx ISE 14.5 software. The multiplier occupies about 15% of total coverage area. The dissipated power and delay of the multiplier are 0.042µw, 3.125ns respectively.

Path planning algorithms provide autonomy in mobile robots to reach targets even in unknown environments. Path planning using grid based techniques such as A ∗ and D ∗ , are cost function based, which is primarily a function of the distance to be travelled to reach the target. Robots targeted for outdoor environments should consider the terrain features also during path planning. In this paper, a modified approach of D ∗ path planning algorithm is proposed. In addition to distance to be travelled, terrain slope estimate is also used in cost function computation to plan the path. The algorithm was simulated and tested with different terrain slopes. Results with different test scenarios are also brought out.

The furthermost eco-amicable challenge nowadays is ecumenical warming. Energy disaster conveys green computing. Dynamic voltage scaling (DVS) has been a crucial procedure in exploiting the hardware characteristics of cloud datacenters to preserve energy by lowering the supply voltage and operating frequency. The study presents modified power consumption can be reduced by live migration of the virtual machines (VM) as required and by switching off idle machines. So, proposed a dynamic threshold predicated approach DMM CPU utilization for host at data center. This consolidation will work on dynamic and capricious workload evading nonessential power consumption. It will meet energy efficiency requisite but would withal ascertain quality of accommodation to the utilizer by minimizing the Service Level Agreement(SLA) contravention. The proposed is a graphic implement Cloud Sim as its simulation engine and offers a facile-to-use utilizer interface, report generation features and engenderment of extensions in a plugin fashion. Dynamic consolidation of virtual machines (VMs) utilizing live migration and switching idle nodes to the slumber manner sanction Cloud providers to optimize resource custom and diminish Energy consumption.

Biofloc (BFT) based nursery rearing system help provides an additional food source, healthy juvenile production with better survival and an avenue for nitrogen removal through eco-friendly approach. It should be cost and energy efficient with a quick turn over. However, many questions remain unanswered regarding mechanisms of action and induced antibacterial/antiviral immune responses in penaeid shrimp especially during nursery phase. The present experiment was designed to evaluate the effects of biofloc treatments generated and maintained through three approaches on growth performances, physico-chemical parameters, microbial dynamics, feed utilization and immunological assessments in P. vannamei nursery rearing. The experiment was conducted in 500 L FRP tanks stocked with PL-III stage of Pacific white shrimp for 30 days at a stocking density of 6000 nos/m3. The heterotrophic bacteria level of 1 × 107 CFU/ml was maintained through three approaches differing in their generation; 1) biofloc lyophilized powder (BFP), 2) biofloc matured water (BFW) and 3) biofloc consortium (BFC) and compared with that of the conventional nursery rearing without biofloc treatment (Control). BFT treatments showed significantly higher growth as observed in average body weight (ABW) (BFP - 0.357 g, BFW - 0.363 g & BFC - 0.391 g) compared to control (0.188 g). BFT groups showed significantly (P

DC-DC converter with high voltage gain is broadly used in more solicitations they are Power amplifier, Battery power system, and automotive, adaptive control. This paper presents the proposed DC-DC converter with high voltage gain for distributed generation system. The realizable difficulty of potential resonance in the midst of junction capacitance and leakage inductance has been neglected. Designing suitable controller for the proposed DC-DC controller is also the required task. PI controller and ANFIS tuned PI controllers have been incorporated to achieve the desired objective with the converter. Simulation results have also been presented for performance validation of the system.

The concept of “biofloc technology” is changing the facet of intensive aquaculture with scope to attain high productivity in a sustainable manner. In biofloc, dense heterotrophic bacterial community is developed through C:N ratio manipulation, where the system becomes bacterial dominated rather than algae dominated and takes care of the wastes generated through in situ bioremediation. Protein is utilised in two ways; as feed for the shrimp and as microbial floc when the heterotrophic microbes convert the nitrogenous wastes into protein. It also promises a healthy rearing system, which is increasingly identified as one possible solution for disease problems especially those striking at early stages. The purpose of this study was to evaluate the effect of biofloc and periphyton technology (BPT) on the growth and immunomodulatory performance of Pacific white shrimp Penaeus vannamei during nursery and grow-out culture. The experimental BPT treatments with three tier substrate system with molasses as carbohydrate (CHO) source were compared with the conventional autotrophic system. Theimmunomodulation and cumulative percentage mortality upon challenge with pathogenic strain of Vibrio parahaemolyticus were assessed in the reared animals. We have successfully demonstrated the BPT based nursery and grow-out systems for P. vannamei with the advantage of providing significantly (p

Autonomous Rover requires navigating unknown areas and reaching target point successfully. Over the course, rovers may get trapped in a deadlock scenario. Rover must be built with intelligence to back trace its path and find an alternate route to avoid the trap situation. Maze is a typical case which can be used to train the rover to deal with such scenarios. This paper brings out a maze solver algorithm which can be implemented in a simple autonomous rover with limited onboard resources. Also the implementation details of the algorithm in LEGO Mindstorms Rover along with the experimental results are brought out here.

Spacecraft Testing forms an integral part of spacecraft realization. The various subsystems of the spacecraft and its interfaces are evaluated through Integrated Spacecraft Tests. During these tests appropriate Telecommands are sent to the spacecraft. The decoding and execution of these commands are verified and confirmed against the expected behavior of various subsystems. Users send instructions using Checkout Command Language (CCL). Telecommands are generated from the CCL based on the project requirements. Total Automation for Spacecraft Checkout aims at providing an automatic test facility to carry out Spacecraft Testing. Based on satellite or project requirements Telecommand code pattern may vary from mission to mission. A Generic Telecommand Executor is developed for catering to Telecommand generation and execution for different projects. This paper brings out the design and implementation aspects of generic Telecommand Executor.

Text mining refers to the process of deriving high-quality information from text. Text processing involves in search and replace in electronic format of text. A number of approaches have been developed to represent and classify text documents. Most of the approach tries to attain good classification performance while taking a document only by words. We propose a concept based methodology instead of terms. It represents the meaning of text to reduce the features. Support Vector Machine (SVM) algorithm is applied for document classification. Then the performance measure is compared with document classification using original features and concept based features. This methodology enhances the document classification accuracy.

The vein structure is stable over time and can be manipulated for identifying human. The sclera portion of the human eye has blood vessel pattern which is unique for each human being. So, the sclera vein pattern can be used for a useful biometric feature. A few research works has been done over finger vein pattern recognition. Finger vein is an important biometric technique for personal identification and authentication. The finger vein is a blood vessel network under the finger skin. The network pattern is distinct for each individual, unaffected by aging and it is internal i.e. inside human skin which can always guarantee more security authentication. Sclera vein pattern recognition can face a few challenges like: the vein structure moves as the eye moves, low image quality, multilayered structure of the sclera vein and thickness of the sclera vein changes with the excitement level of the human body. To overcome this limitation, the multimodel biometrics is proposed through which the user can be authenticated either sclera vein or finger vein recognition. Sclera vein recognition used Y-shape descriptor and finger vein recognition used repeated line tracking based feature extraction method to effectively eliminate the most unlikely matches respectively. According to the available work in literatures and commercial utilization experiences, sclera vein and finger vein multimodality ensures higher performance and spoofing resistance. Thus building the multimodel biometric system increases the population coverage and improves the accuracy of the human recognition.

2 Abstract: Multiplication is one of the most critical arithmetic operation, which is extensively used in many VLSI systems such as application specific based digital signal processor architectures and microprocessor. Multipliers are the major source of power dissipation in the VLSI systems. By reducing the power consumption of the multipliers the power consumption of the VLSI system can be reduced. This paper presents the CLRCL full adder based 4*4 Wallace and Dadda multipliers. The CLRCL full adder has only ten transistors which is less in number when compared with conventional full adders which is used to design these multipliers. Designing Wallace and Dadda multiplier by using CLRCL full adder will reduce the transistor count and power consumption. The proposed design is simulated using 0.12µm.

In recent years, power dissipation is one of the biggest challenge in VLSI design. Multipliers are the main source of power dissipation in DSP block. Power of any multiplier can be reduced by designing a full adder which will consume very less power. So a lot of researches have been made to decrease the power consumption of the full adder. Here a structured approach for analysing the Wallace and Dadda multiplier is introduced. These multiplier are designed using existing full adders like 28T,16T,14T, and TGFA. These designs are studied and the analysis is made based on the simulation parameter like no of transistors count and power consumption using micro wind tool.

This dissertation exploits an Android base application gives clarification to assist parents to pathway their adolescent activity. It was implemented to locate the location based on real time map only when the user is found to be missing or kidnap cases. A parent's tool has to propel a application spot SMS to the child's tool to acquire the spot of the child. On the other side, the child's tool accept the acknowledgement and retort the GPS spot to the parent's tool upon request, but it was costly and was intricate as information's can be customized. This is based on Douglas peucker algorithm. This application provides the adolescent to be secure from the susceptible milieu by monitoring their commotion by exploring the android hook up in a smart handset of the adolescent tenuously.

Ever increasing number of accidents while driving can be significantly reduced if modern technology is introduced within the automobile to monitor the physical condition of the driver at every instance during the movement of the vehicle and precautionary measures are taken for the safety of the driver. In this paper, a design of drowsiness detector system and pedal mix-up avoidance is presented. Detection of drowsiness is introduced which can monitor the eye movement and eye blinking of the driver at regular intervals during his/her driving and, if required, can provide an audible alarm within the vehicle to alert the driver or introduce braking system. Pedal mix-up avoidance system is a system used to avoid the sudden unintended acceleration caused by a driver while parking, traffic jams or under disastrous consequences. In case of pedal mix-up, when the vehicle is in parking or traffic jam or under an unconscious state of mind, he/she might mistakenly raise the gas level instead of brake which leads to disastrous accidents. Under such situations, unintended acceleration avoidance system decides the correct pedal and raise the brake whenever mistakenly accelerator is been raised. The design of the system has been successfully implemented which produces an outcome that such a system can help in avoidance of sudden unintended acceleration and also help in keeping the driver awake while driving. Thus, this system facilitates in avoidance of any traffic accidents.

Al-decorated, single-walled carbon nanotube has been investigated for hydrogen storage applications by using Density Functional Theory (DFT) based calculations. Single Al atom-decorated on (8,0) CNT adsorbs upto six H 2 molecules with a binding energy of 0.201 eV/H 2 . Uniform decoration of Al atom is considered for hydrogen adsorption. The first Al atom has a binding energy of 1.98 eV on (8,0) CNT and it decreases to 1.33 eV/Al and 0.922 eV/Al respectively, when the number of Al atoms is increased to four and eight. Each Al atom in (8,0) CNT-8Al adsorbs four H 2 molecules, without clustering of Al atoms, and the storage capacity reaches to 6.15 wt%. This gravimetric storage capacity is higher than the revised 2015 target of U.S Department of Energy (DOE). The average adsorption binding energy of H 2 in (8,0) CNT-8(Al+4H 2 ), i.e. 0.214 eV/H 2 , lies between 0.20 and 0.60 eV/H 2 which is required for adsorbing and desorbing H 2 molecules at near ambient conditions. Thus, Al-decorated (8,0) CNT is proposed as a good hydrogen storage medium which could be useful for onboard automobile applications, at near ambient conditions.
