In this paper, an analytical model is developed and investigated for the transverse deflection in a transversely isotropic, thermoelastic simply-supported beam resonator subjected to time harmonic patch loading. Closed form expressions based on Euler–Bernoulli beam theory are derived for the flexural vibrations in a transversely isotropic, thermoelastic micro-beam. A time harmonic patch load is assumed to act within the region of the beam. The Laplace transform technique has been used to find the transverse deflection in the transform domain due to patch loading on the beam. The deflection so obtained in a physical domain has been computed numerically with the help of MATLAB software and presented graphically for silicon material beams.Keywords

Fingerprint recognition is a method of biometric authentication that uses pattern recognition techniques[1] based on high-resolution fingerprints images of the individual. Fingerprints have been used in forensic as well as commercial applications for identification as well as verification. The fingerprint surface is made up of a system of ridges and valleys. The steps for Fingerprint recognition include image acquisition, preprocessing, feature extraction and matching[2]. In the present work, a new fingerprint feature detection algorithm has been proposed. It has been found that presence of noise in fingerprint images leads to spurious minutiae. To overcome this problem, feature extraction has been done which efficiently determine the minutiae points in fingerprint [1]. The proposed method can be used in matching the template for finding bifurcation and termination. The new smoothing algorithm is proposed for the detection of the features of fingerprints. A method has been introduced for finding ridges in the fingerprint image with the help of eight different masks. It is a process of making a binary image of ridges from the grayscale fingerprint image. The experimental results showed the accuracy of the algorithm in terms of genuine acceptance rate, false rejection rate, false acceptance rate.Keywords

The process of edge detection plays a significant role in image processing and vision processing. True edge detection is very difficult to achieve because intensity varies sharply and has discontinuities. Many methods have been developed by researchers in last few years. After studying the literature on color edge detection, we figured out that advanced algorithm using fuzzy logics have attained high figure of merit (FOM) value of 1with small threshold values but as the value grows higher the FOM value reduces. In this paper an algorithm has been proposed in order to achieve high figure of merit by varying threshold in color edge detection. In this algorithm, there is an improvement over previously proposed edge detection using fusion of hue-difference and PCA image. The results are promising.

In a wireless network, there is a large number of mobile nodes that share the communication medium. The wireless network employs carrier sense based MAC algorithms such as Carrier Sensing Multiple Access (CSMA) and CSMA with Collision Avoidance (CSMA/CA) for efficient sharing of communication channel. But this method does not solve the problem of hidden nodes. Hidden nodes are those nodes that are out of range of other nodes or a group of nodes. The network throughput reduces because of packet collisions caused by these hidden nodes. To solve hidden node problem, the Request-To-Send (RTS) and Clear-To-Send (CTS) mechanism is widely used in wireless networks for reserving the channel to transmit data from source to destination. This paper is aimed to provide a survey on methodology and various algorithms and methods of implementing RTS/CTS mechanism in wireless networks.Keywords

Internet is no longer a mere source of information as the concept of interconnectivity has expanded to connect real things or objects like every kind of machines, cars, homes, hospitals, even our bodies through wearable devices. The concept of interconnectivity of billions of objects (mobile or stationary) providing and exchanging real time data is called Internet of Things (IoT). Myriad IoT applications are touching every aspect of our lives and have the latent to develop the basic quality of life for masses. However, prerequisite for successful implementation of any IoT application is uninterrupted and high-quality network connectivity and handling of huge amounts of personal and sensitive user data which gives rise to the questions of security. A handoff authentication protocol with high security and efficiency is required for enabling secure and seamless handoff of mobile nodes between different access points (AP). However, there are number of challenges in designing a secure handoff protocol for IoT systems like limited power of mobile nodes, computational capability, security and vulnerability of open IoT networks. In this paper, we propose a secure and reliable handoff authentication protocol for such IoT devices. Compared with other well-known similar handoff protocols, the protocol proposed here satisfies all relevant security requirements of handoff such as batch verification, mobile node un-traceability, and anonymity and is unaffected by other attacks like replay attacks and also provides mutual authentication. To demonstrate the security strength (against replay attacks) of our protocol, simulation has been done using AVISPA. Thus, protocol proposed by us is more appropriate for IoT environment compared to the alike protocols.Keywords

Background of the study:
Cessation of menstruation termed as menopause is the most striking feature during the period of transition from the reproductive to the non-reproductive stage of life. Due to hormonal changes women may experience a wide range of physical, psychological and social problems. Issues associated with their fertility and decreased reproductive functioning makes them feel less desirable in the society. Psychological symptoms cause more damage to daily life and are also most often neglected. Stress due to transition includes adjusting to the changing self, adapting to alterations in sexuality caused by hormonal shifts. Coping strategies help the women to overcome these problems and lead a normal life.
Aim: The aim of this study was to assess the psychosocial problems and coping strategies of postmenopausal women in selected communities of Ludhiana.
Objectives of the study:
The objectives of the study are;
1. To determine the level of psychosocial problems among postmenopausal women
2 To find out the coping strategies among postmenopausal women.
3. To find the association of psychosocial problems and coping strategies with the demographic variables.
Method: A descriptive survey approach was used for the study. The sample consisted of 50 postmenopausal women, selected by purposive random sampling method. Data was collected by structured interview schedule on psychosocial problems and coping strategies among postmenopausal women prepared by the investigator. The collected data was analyzed using descriptive and inferential statistics.
Results: The findings showed that 37(74%) of postmenopausal women were having moderate psychosocial problems, 13(26%) of them were having mild psychosocial problems and none of them were having severe psychosocial problems. Majority (74%) of the postmenopausal women adopted adequate coping strategies and the least (26%) of them adopted inadequate coping strategies.
The study showed that there is a significant association of the level of psychosocial problems with the selected demographic variables like educational status, monthly income, religion, most supportive person in the family and the duration of menopause. The calculated χ2 value of educational status (χ2 = 7.68), monthly income (χ2 =24.88), religion (χ2 = 8.14), the most supportive person in the family (χ2 = 13.93) and duration of menopause in years (χ2 = 12.75) were more than the table values at 0.05 level of significance. Hence null hypothesis is rejected and research hypothesis is accepted. The findings also shows that there is no significant association of the level of psychosocial problems with the selected demographic variables like age, marital status, occupation, type of family, member of any social groups, parity and age of achievement of menopause. The calculated Chi-square value for age (χ2 =3.06), marital status (χ2 =2.71), occupation (χ2 =1.33), type of family (χ2 =0.24), member of any social groups (χ2 = 0), parity (χ2 = 4.04) and age of achievement of menopause (χ2 = 1.05) were less than the table value, hence the null hypothesis is accepted.
The study showed that there was a significant association of the level of coping strategies with the selected demographic variables like age, marital status, educational status, occupation, monthly income, age of achievement of menopause and duration of menopause (in years). The calculated χ2 value of age (χ2 =11.52), marital status (χ2 = 10.52), educational status (χ2 = 8.86), occupation (χ2 = 4.63), monthly income (χ2 = 15.92), age of achievement of menopause (χ2 = 7.98) and duration of menopause in years (χ2 = 10.45) were more than the tables value at 0.05 level of significance. Hence null hypothesis is rejected and research hypothesis is accepted. The findings also shows that there is no significant association of the level of coping strategies with the selected demographic variables like religion, type of family, member of any social groups and parity. The calculated Chi-square value for religion (χ2 =3.85), type of family (χ2 = 1.27), member of any social groups (χ2 = 0) and parity (χ2 = 0.78) were less than the table value, hence the null hypothesis is accepted.
Interpretation and conclusion: The finding of the study have certain important implications for the nursing profession such as in nursing practice, nursing education, nursing research and nursing administration. This study was conducted with the objective to assess the psychosocial problems and coping strategies among postmenopausal women at Ludhiana.

This paper regarding the use of the natural phenomenon’s based optimization techniques to resolve the problem of nonclustered nodes. Objectives: This research minimizes energy consumption. Its objective is to provide efficient clustering for avoidance of residual nodes and prevents occurrence of dead nodes with usage of mobile nodes. Methods: In this research paper firstly deploy number of mobile nodes in specified region with usage of MATLAB environment. For grouping of these nodes LEACH protocol uses for clustering. During clustering with LEACH some nodes residual and not become part of any cluster. Firefly Optimization used for prevention of residual nodes and efficient clustering. It uses distance and light intensity parameters for clustering. GSA algorithm used for finding best path for data transmission with less energy consumption. Findings: In this research paper shows efficient clustering of nodes with prevention of residual nodes. In existing LEACH protocol some static nodes are residual and not become part of any cluster. These nodes send data directly to base station and consume large amount of energy. These individual nodes die early due to maximum energy consumption. But in this research mobile nodes are used and occurrence of dead nodes prevented on basis of distance and light intensity parameters. Nodes which are at minimum distance are brighter than farthest nodes. Minimum distance nodes join nearest cluster and prevent formation of remaining nodes. Improvements: In this paper results shown that it performs better in terms of network lifetime, energy consumption, end to end delay and throughput and number of dead nodes.Keywords

The pretest mean knowledge score in control group and experimental group was 16.33, 16.20 respectively and where as the post test mean knowledge score in control group and experimental group was 16.46, 26.03 respectively. The difference of pretest posttest mean knowledge score of antenatal mothers in control group was statistically not significant whereas it was statistically significant in experimental group. The tcal 0.1442 < ttab 1.96 in control group whereas in experimental group tcal 15.2915 > ttab 1.96. So the difference of post-test mean knowledge score of experimental group was statistically significant at p<0.05 level. Thus, it indicated that Exhibition had significant impact on knowledge regarding pregnancy induced hypertension among antenatal mothers in experimental group. In this study posttest knowledge score was not associated with any socio-demographic variables.Keywords

As concerned with wireless networks, the communication is done through the radio links where chances of unauthorized user are more which consequently degrades the performance of network and result is more delay. Wireless networks are broadly classified into two broad categories: infrastructure mode and infrastructure less mode. Various protocols are defined under this which uses their different mechanism for detection and isolation of the wormhole attacks. In this paper some of the studies are defined on the basis of methods used for the detection and avoidance of attacks adhere to its use in it. As the numerous attacks may arise over network on MANET, their comparison has been discussed on the basis of techniques and their effects.
This paper intends to find out all the possible ways to detect and avoid the wormhole attack in the network. It may not lead to complete isolation of the attack but plays an important role to reduce the wormhole attack.

Due to the extensive range of applications the use of wireless sensor networks (WSNs) in past few years have increased a lot and it has become a hot research area now a days. One of the important issues in wireless sensor network is the intrinsic limited battery power in network sensor nodes. Since most of the energy is consumed by the transmission and reception, energy efficient routing protocol is required to enhance the lifetime of WSN. In this paper we presents the review of existing hierarchical routing protocol NEW LEACH and proposed a new approach that is better and more energy efficient than the existed approaches. In the proposed work, two enhancements are made. These enhancements are efficient cluster head replacement technique by using dynamic threshold value and the concept of upper threshold for sending data. Both NEW LEACH and Proposed protocol are simulated in MATLAB. The result shows that our proposed algorithm performs better than the NEW LEACH in terms of network lifetime.Keywords

Speckle noise is an intrinsic yet undesirable residual part of the medical ultrasound images, which considerably degrades the visual quality and limits the accuracy of automatic diagnostic techniques. Hence speckle suppression is an essential task before the examination and processing of the medical ultrasound images. Aiming at the problem of multiplicative speckle noise, an improved despeckled method is proposed in this paper, which is based on WaveletShrinkage_Guided filter. The proposed method used the Daubechies20 (d20) wavelet transformation to decompose the ultrasound images and an improved wavelet shrinkage algorithm to filter the high-frequency component. The wavelet coefficients of low-frequency sub-bands are filtered by an improved guided filter with varying regularization parameter and the inverse DWT is used to obtain the noise free image. Synthetic image and an ultrasound image experiments with the comparison of the Guided filter and WaveletShrinkage_Guided filter are carried out. The quantitative results of the proposed strategy show, that it outperforms the other despeckling methods in terms of favorable speckle suppression and edge preserving factors.Keywords

One of the main hurdles in boosting the agricultural production in arid and semi arid areas of world is the scarcity of good quality water for irrigation. The quality of irrigation water plays a key role in judging its suitability for crop production. Soil and water salinity is an abiotic stress and limiting factor which affects almost every aspect of physiology and biochemistry of a plant, resulting in reduction in its yield. The research entitled alleviation of saline water stress on tomato (Lycopersicon esculentum Mill.) plants by irrigation scheduling and foliar application of salicylic acid and potassium sulphate. was conducted at Niche area of excellence, S.K. Rajasthan Agricultural University, Bikaner during Rabi season of 2015-16. The result shown that biochemical parameters APX, SOD, POX and CAT activity significantly increased with the increase in irrigation interval from daily irrigation to third day irrigation. The effect of irrigation levels on APX, SOD, POX and CAT activity significantly increased from 1.0 vol. (full volume of water required by crop) to 0.8 vol. (80% of full volume of water required by crop) and at par to 0.6 vol. (60% of full volume of water required by crop). The application of salicylic acid and potassium sulphate resulted in significant increase in APX, SOD, POX and CAT activity over control at application of 500 ppm and 15 m mol, respectively. The physiological parameters viz., electrolyte leakage and relative leaf water content (RLWC) decreased with the decreasing irrigation levels from 1.0 vol. to 0.8 vol. and at par to 0.6 vol. The electrolyte leakage and RLWC decreased with the increase in irrigation interval from daily to third day irrigation. With the application of salicylic acid and potassium sulphate the physiological parameters increased significantly. The quality parameters also fluctuate with the treatments. The TSS and ascorbic acid content of tomato decreased with the increase in irrigation levels as well as irrigation intervals and increased with the application of salicylic acid and potassium sulphate. The similar results were found with the yield and yield attributes, the number of fruits per plant, avg. diameter of fruit, avg. weight of fruit and yield of fruits decreased with the increase in the irrigation interval and irrigation levels and increased with the application of salicylic acid and potassium sulphate. The soil was non-significantly affected with all the treatments of research.Keywords

The present investigation was carried out for assessment of soil fertility status of Jaisalmer district of western Rajasthan. For this purpose 125 representative soil samples were collected from two Panchayat Samiti i.e. Sankda village Ujala and Jaisalmer village Basanpeer and Amersagar of Jaisalmer district. These soil samples were analyzed for soil properties, macro and micronutrient fertility status. The soils were moderately alkaline to very strongly alkaline in reaction with an average pH of 9.75. The EC value varied from 0.05 to 0.71 dS/m with average value of EC is 0.25 dS/m. The organic carbon content ranged from 0.01 to 0.70 per cent with an average value of 0.09 per cent. Available nitrogen, phosphorus (P2O5), potassium (K2O) and sulphur (ppm) content of the soils ranged from 13.53 to 230.07, 5.43 to 56.72, 170.13 to 379.95 kg ha-1 and 0.88 to 21.76 ppm with an average value of 131.95, 25.96, 258.13 kg ha-1 and 11.34 ppm, respectively. However, available micronutrient DTPA Zn, Fe, Cu and Mn ranges varied from 0.04-1.63, 1.05-3.94, 0.01-0.21 and 0.14-2.88 ppm with an average value of 0.51, 0.21, 0.09 and 1.55 ppm per hectare, respectively. Among major nutrients, about 100 per cent of the soil samples were low in available nitrogen, 57.60, 36.00 and 6.40 per cent soil samples were observed to be low, medium and high in available P2O5, 87.20 and 12.80 per cent samples were in medium and high in available K. whereas, 44.80, 54.40 and 0.80 per cent soil samples were observed to be low, medium and high in available sulphur. Nutrient indexing of the areas was low for N (1.00), Cu (1.016) and Mn (1.112), whereas, it was medium in case of phosphorus, potassium, sulphur, DTPA-Zn and Fe. With respect to micro-nutrients 66.40, 46.40, 99.2, 94.40 per cent samples were found to be deficient in DTPA-Zn, Fe, Cu and Mn, respectively. The correlation studies among the chemical characteristics showed that organic carbon contributed most towards nutrient availability and found to be positively correlated with all parameters except pH and Zn.Keywords

Field experiment was carried out during Kharif 2017 at Ludhiana and Gurdaspur to assess the weed density, DMA of weeds and chlorophyll content as influenced by straw mulching and herbicides in maize.Application of paddy strawmulch at 9.0 t ha-1 effectively controlled the density and DMA of grasses, broadleaf and sedges and resulted in significantly more leaf chlorophyll content in maize as compared to paddy straw mulch at 6.25 t ha-1 and no mulching. Pre-emergence application of atrazine at 1.0 kg ha-1 helped to manage density and DMA of grasses, broadleaf and sedges in comparison to atrazine at 0.8 kg ha-1 and unweeded check at 20 DAS. At 40 DAS of maize where maximum losses due to weeds occurred, the weeds were managed by post emergence application of tembotrione at 0.088 in combination with PSM 9.0 t ha-1which reduced the density and DMA of grasses, broadleaf and sedges in comparison to atrazine at 0.8 and 1.0 kg ha-1 and unweeded check, but were equally effective as compared to tembotrione at 0.110 kg ha-1 and weed free treatment. The data showed that application of 9.0 t ha-1mulch helped to reduce 20 per cent dose of atrazine and tembotrione for controlling weeds in maize.Keywords

A multi location experiment was conducted at Punjab Agricultural University, Ludhiana and Regional Research Station Gurdaspur (PAU) during Kharif 2017 to evaluate the effect of straw mulching and herbicides on soil temperature, PAR interception and crop phenology of maize. Application of mulch at 9.0 t ha-1 helped to reduce the soil temperature at 5 cm soil depth by 3.8 to 4.6°C at 20 DAS, 1.0 to 1.4°C at 40 DAS, 1.0 to 1.3°C at 60 DAS and 0.7 to 1.2°C at harvest as compared to no mulch treatment, but at 10 cm soil depth the temperature was reduced by 2.2 to 3.7°C at 20 DAS, 1.3°C at 40 DAS, 0.5°C at 60 DAS and 0.4°C at harvest at both the locations. High values of PAR interception and less number of days taken to tasselling, silking and physiological maturity were recorded with application of PSM 9.0 t ha-1 as compared to PSM 6.25 t ha-1 and no mulching treatments. Mulch application at 6.25 t ha-1 also significantly lowered the soil temperature and resulted in significantly higher PAR interception and less number of days to tasselling, silking and physiological maturity as compared to no mulch treatment. Different weed control treatments did not significantly influence the emergence of maize and soil temperature at 5 cm and 10 cm depth at both the locations. Application of tembotrione at 0.088 kg ha-1, tembotrione at 0.110 kg ha-1and weed free treatments recorded statistically similar but significantly higher values of PAR interception and less number of days for tasselling, silking and physiological maturity as compared to atrazine at 0.8 and 1.0 kg ha-1 and unweeded check.Keywords

This study is an attempt to test the validity of trinity hypothesis and to measure the cost of capital account convertibility which Indian economy has paid in the form of one of the cornerns of trinity triangle. The monthly data obtained from various publications of RBI and IMF over the period 1980:M1 to 2016:M12 have been utilized to construct three trinity indices of Monetary Independence (MI), Exchange Rate Stability (ERS), and Capital Account Openness (CO).Using the graphical and cointegration tools, the existence of trinity hypothesis has been confirmed in Indian context. It has been noticed that India has clearly chosen capital openness (CO) over exchange rate stability (ERS).References

Many national and international agencies blame demonetization as a major factor behind the deceleration in the growth rate of Indian economy in recent quarters. Such linkages of economic growth with monetary shocks have been well explained by Hawtrey’s monetary theory of business cycles. The present paper attempts to test Hawtrey’s theory in the context of demonetization in India. The results indicate that the Indian economy did experience fourteen growth-rate cycles over the period 1970 to 2017. Given that M3 takes an average 7 months lead in explaining the low growth (i.e., downswing) phase, the demonetization (i.e., fall in money supply) can be admitted as a lead because of falling growth rate of Indian economy.References

This paper examines the effectiveness and relative strength of various channels of monetary policy transmission in India during the post reform period using the monthly data spanning over 1991:M4 to 2017:M12. The analysis has been via regular and seasonal unit ischolar_main methods and graphical method has been applied for identification of structural breaks. Alternative methods namely, HEGY, Augmented Dickey Fuller (ADF), Phillips-Perron (PP), KPSS and DF-GLS have been applied for testing the presence of seasonal and regular unit ischolar_mains. The long-run and short-run behaviors of different channels have been analyzed through Structural Vector Error Correction Model (VECM). In India, first and second important channels of monetary policy transmission mechanism are Credit and Interest rate.Keywords

In the hyper-connected world, data has been playing a significant role in earthing the system of every domain that one can think of. But, it is undeniable fact that today data has prone to serious threats as it was never before, which has questioned the reliability, integrity as well as security of data. So, the technology has emerged that can mitigate all these issues, and that technology is none other than the technology residing at the heart of Bitcoin, The Blockchain.
Blockchain is one of the powerful technologies that has brought a revolution in conventional trading techniques. Conceptually, it is an open and distributed ledger that maintains an irrefutable database of records of all transactions or values that have been executed and shared peer-to-peer directly obsoleting the need for trust-worthy intermediatory in a secure, verifiable, moreover, in a permanent way alleviating the risk of fraud.
The main objective of this paper is not only to make blockchain a common business trading language but also to present its compelling applications in contrasting domains that are beyond currency rides, specifically in healthcare, politics, and its strategic implications in bridging strong economy using smart contracts that can revolutionize our digital global village.

Himachal Pradesh (HP), one of the 11 states of the Indian Himalayan Region, has a prolonged history of landslides and related mass-movement activities. In recent years, landslide incidences have increased significantly in the state due to changing climatic patterns and enhanced anthropogenic interventions. Therefore, to understand the spatial distribution of landslide-prone zones, regional-scale landslide susceptibility mapping for the entire state has been carried out using two bivariate methods, i.e. weight of evidence and information value. The results depict that 25–30% of the total area of the state is confined in the high to very high landslide susceptible (LS) zones. These are dominantly confined to three regions: Kinnaur, Lahaul, Chamba and upper Kangra. It is also ascertained that a higher percentage of high and very high LS zones are located at an elevation of 2000–4000 m and on the slopes facing south with an inclination ˃40°. Moderate and low to very low LS zones comprise ~27% and ~43–48% of the total area respectively, and are confined to the Outer and Lesser Himalaya. These maps were validated using the success rate curve and prediction rate curve, indicating that both models have more or less similar efficiency and accuracyKeywords
