Published: October 2019

Abstract
In the Existing System, Mobile must be unlocked before using. The widely usage of unlocking types are PIN, password and graph. In the Proposed System, we propose a novel token-based mobile device unlocking approach: transferring the authentication state between two devices by briefly shaking them conjointly. In this system; we propose 4 attributes for phone unlocking. 1. Hand waving pattern in mobile, 2. Creating information from embedded hardware through Bluetooth, 3. MEMS waving pattern by the hardware device, 4.Synchronization of both the device. The unlocking pattern of the mobile will be changing every time for safety reasons, It will be changing randomly. The major advantage of this system, even if hacker knows one of the above specified unlocking password, he have to provide answer based on the required pattern so this is more secured application. We also implement Women’s Safety application along with this implementation. We include two patterns for this application. Pressing the switches in the hardware or Phone’s waving pattern is matched immediately system will understand that Women safety application is initiated. GPS is initiated to save the women by sending location info both to the Guardian and Police.

Abstract
Diabetes and Cholesterol has become a common disease all over the world. Continuous monitoring of the glucose and cholesterol levels is needed in case of physically disabled and unconscious people where it is hectic to take measurements invasively or through blood samples. The proposed model brings out an idea of measuring glucose and cholesterol levels without the need of blood samples or involving contact. This is done with the help of simple IR sensors and Arduino UNO. The patient’s fingers are placed on the IR sensor and power LED sockets with one involving in the measurement of cholesterol and other in measurement of glucose. For the diabetic patients and pregnant ladies have to monitor the glucose and cholesterol level frequency. The minimum level of cholesterol in blood is causes to the cardiovascular disease, that leads to stoke and heart attack. Based on the reflection of power LED light through the blood cells, the values are fed to the Arduino UNO. With the help of program dumped in the Arduino UNO, glucose and cholesterol values are calculated. In addition to that Hemoglobin and also LDL and HDL values are also calculated which is a further advantage. The proposed model costs less and saves more time. Further advancements can be done by employing this project by using IoT which can feed the measured data online. Non invasive measurement methodology of measuring glucose and cholesterol is not implemented anywhere which describes the uniqueness and innovation involved in this method.

Abstract
In recent days, Wireless Power Transfer (WPT) and harvesting energy received lots of attentions due to the necessity of having a flexible, suitable and secure source of energy. With the explosion of wireless technologies including wireless sensor network (WSN) like internet of things, such intelligent systems had highlighted this need. Wireless power transfer is a key technology to enable any device operation without replacing their batteries, often challenging due to cost of replacement and the difficulty to reach inaccessible areas. Anyhow wireless power transfer is being considered as eco-friendly. This also removes the need to dispose dead batteries. Inductive coupling can be used to charge the low power devices quickly and effectively without the help of wires. This method is done by using charging a resonant coil from AC and then transmitting subsequent power to the resistive load. In this case, oscillating circuit is used in the conversion of DC to AC in order to transmit the magnetic field by passing frequency and inducing the receiver coil. The system is designed and constructed as two parts. They are Transmitter part and Receiver part. To calculate the inductive coupling between the transmitter oil and receiver coil, Ampere’s Law, Biot-Savart’s Law and Faraday’s Law are used as per the requirement.

Abstract
Weather forecasting is one of the applications of science and technology, used to predict the weather condition depending on the input attributes. Most of the existing systems are implemented using statistical approaches for Support Vector Machine (SVM), which are incapable of giving the accurate prediction as they cannot capture sudden changes in weather conditions. The proposed technique uses the concept of Multi-Linear regression which can produce better results than existing methods.

Authors: Anna Devi E. , Martin Leo Manickam J. 
Published: October 2019

Abstract
In wireless sensor network (WSN), energy efficiency and network lifetime are the important attributes to be improved for enhancing the performance of the network. Due to the failure or cut of a node, performance of the network is affected. So cut node detection and recovery are presented in this paper. Initially, sensor nodes in the search area are clustered using the node weight of the sensor nodes. The node with maximum weight is selected as cluster head (CH) and this CH performs as a monitor node which monitors all non-CH members in a cluster. Backup nodes (BNs) are selected in each cluster using Particle Swarm Optimization (PSO) algorithm. Cut node in the network is detected based on its hop-count and link cost value. This cut node is recovered by the selected backup nodes and mobile nodes (MNs) in the network. Simulation results show that the performance of the proposed approach outperforms that of the existing approach in terms of overhead, energy efficiency, network lifetime and BN selection time.
Quantitative assessment of interfacial condition of cold joint using surface wave group velocity profile
Authors: Lin Y-C , Cheng C-C , Chiang C-H , Hsu K-T 
Published: October 2019

Abstract
Improperly constructed cold joints lead to poor water tightness. Water, chloride ions, and other harmful substances can therefore enter through the joint, causing the accelerated corrosion of steel bars. In this study, the surface wave group velocity profile, which can identify velocity at variant depths beneath concrete surfaces, was used to determine the interfacial condition of a cold joint. The proposed test method performed a single test with one impacting source and one receiver placed on a concrete surface across the joint. The short-time Fourier transform (STFT) and the reassignment technique were used to process the received signal and obtain the image of the group velocity spectrogram. The surface wave group velocity profile was then extracted from the spectrogram. A 0.4 m-thick reinforced concrete wall containing a cold joint was constructed for the experimental studies. The experimental results revealed a sudden decrease in wave speed for wavelengths larger than 0.2 m: the Rayleigh wave speed dropped from 2,000 m/s for normal concrete to 1,300 m/s for concrete including a cold joint. These results suggest that the rebars near both sides of the wall surface constrained the joint from separating up to the depth of 0.1 m; however, a poor interfacial condition was found near the center of the wall.
Study on the optimum nano-natural pozzolan content in the concrete binder
Authors: al-Swaidani A M , Meziab A 
Published: October 2019

Abstract
The objective of this study is to investigate the optimum nano-natural pozzolan (NNP) content in the NNP-based binder concrete. NNP was obtained by grinding a local volcanic scoria for six hours. Twenty-four concrete mixes with four w/b ratios (0.4, 0.5, 0.6 and 0.7) and six-replacement levels of NNP (0%, 1%, 2%, 3%, 4%, and 5%) have been produced. The investigated concrete properties were the compressive strength, the water penetration depth, the concrete porosity and the chloride ion permeability. The efficiency factor (k) of NNP in terms of compressive strength was calculated using the Bolomey equation. Durability indicators have been used to globally evaluate the behavior of NNP-based binder concrete versus control concrete. The results revealed that the efficiency factor (k) decreased to some extent when the NNP content was more than 4%. The calculated durability indicators showed that NNP contents of 3-4% had approximately the highest indicators values. These indicators would be helpful for concrete mix designers. Some correlations between the investigated properties were derived from the analyzed data. The modification of the microstructure of NNP-based cement paste has been observed, as well.

Abstract
Procurement of construction projects in Nigerian Federal Universities has been affected by unethical procurement practices amongst the stakeholders and projects parties concern. This study aims at developing a framework to mediating the large negative effects of unethical procurement practices on construction projects development. Conflict of interest factors, especially at the tender and bid evaluation stages, were identified as the major unethical practices affecting construction procurement processes of infrastructure projects negatively. Data were collected using a survey questionnaire distributed to construction procurement stakeholders of nine randomly selected Nigerian Federal Universities. Mediation effect of ethical procurement practices was tested between the conflict of interest factors and procurement of construction and infrastructural projects. The findings revealed that conflict of interest factors were found to have large negative effects on procurement of construction and infrastructural project, and ethical procurement practices identified and introduced as mediating variables were tested and verified to possibly mitigate the effects of conflict of interest factors affecting the procurement of construction and infrastructural projects in Nigerian federal universities. Hence, the study recommends that procurement entities concern should ensure compliance with Public Procurement Guidelines (PPGs), which highlights ethical requirements for tendering, bid evaluation and construction processes for the procurement of construction and infrastructural projects.
Influence of material spatial variability on slope stability in soft rock
Authors: Hsu S C , Hsieh T P , Tsai P H 
Published: October 2019

Abstract
Impacts of material spatial variability usually are not considered in traditional slope stability analyses. However, most geotechnical materials are not uniform inside a slope. The objective of the present study was to evaluate the impact of material spatial variability on slopes in soft rocks. The random field model was used to obtain the material spatial variability. The numerical analyses of slopes in soft rock mass were performed using a distinct element method based program UDEC. After that, Monte Carlo simulation, UDEC, and random field models were used together to analyze the impact of material variability and the slope stability. A series of numerical experiments were performed to understand the effect of joint spacing, joint angle, and size of scale fluctuation (δ). Also, failure types and mechanisms were synthesized and evaluated. The probability of failure became higher as the slope considered horizontal spatial variability of the material. The influence of the horizontal size of δ on slopes without joints was much higher than the slopes with joints. In addition, the slopes with joints yielded fewer failures as δ increased. The results of the analyses could be used for prevention of slope failure, future support system, and geotechnical exploration.

Abstract
In tunnel construction in the city area, NATM method is adopted for construction by the limitation of the construction condition. When classifies roughly in supporting method of construction, there are against the spring water, face stability, ground surface subsidence, cement, water glass and urethane are usually used for grouting material against the spring water, but there is the concern, such as expensive and high load on the environment because of artificial materials. On the other hand, Kaolinite is a natural material, there is less load on the environment, and many merits in the processing of the excavated muck. Therefore, we focused a pressurized clay injection method by using the above-mentioned characteristics and applied this to the construction of the underground. In this paper, the availability of the injection a fluid with a dispersion of kaolinite was discussed to summarize the applicability for controlling groundwater of the saturated sand layer. Specifically, a one-dimensional column test was conducted under the high hydraulic gradient. As a result, it was shown the possibility of effecting of decreasing hydraulic conductivity at less than one-order. Consequently, it is concluded hydraulic conductivity of sand layer was able to be reduced by Kaoline clay suspension.
The potential of using performance information in the assessment of existing quay walls
Authors: den Adel N , de Gijt J G , Wolters H J , Schweckendiek T 
Published: October 2019

Abstract
The design of new and assessment of existing quay walls is subject to large uncertainties. Dealing with these uncertainties is a crucial part of the engineering process. The way uncertainties are addressed has a large impact on construction and maintenance costs and on the reliability ultimately obtained. Especially in the assessment of existing structures the uncertainties can be large. An existing structure allows us to use actual performance information in the assessment, such as the structural response to loading. One way to obtain the structural response is test loading assisted by monitoring. In this research Bayesian updating is used to reduce uncertainties and to more effectively use the obtained measurement data. We present a case study of an existing quay structure along with fictitious measurement data to demonstrate the potential effects of test loading on the reliability of the structure. The results show that Bayesian updating successfully reduces the uncertainty (i.e. standard deviation) of the model prediction. Using monitoring data and Bayesian updating provides a more realistic model of the capacity of the existing quay structure and thus a more accurate reliability assessment. Which may lead to extension of the structure’s lifetime or that higher loads can be accepted.

Constructing uncertainty budget for a two-dimensional hydraulic model
Authors: Ozbey N , Gül U S 
Published: October 2019

Abstract
In this study the combined uncertainty of a two-dimensional (2D) hydraulic model expanded at 95% confidence level is estimated and the uncertainty budget for the model outputs is attempted to be constructed. It has been shown that many uncertainty sources in the inputs as well as the procedure applied have a significant impact on the accuracy of two-dimensional hydraulic modelling: the uncertainties in the model inputs due to variations in Manning’s ‘n’ Coefficient assigned, the bridge modelling methods, the equation sets; Diffusion Wave and Full Momentum Equations employed and the geometric data sets for the same river system in the Black Sea Region of Turkey are assessed. To estimate an appropriate M‘n’C and other model inputs of model for a river system with a wide 2D flow area is a daunting task. Therefore, any attempt to quantify uncertainties in the assigned values must be based on the samples large enough to obtain statistically significant results. To achieve this task, Monte Carlo Method is utilized to estimate the contribution of the likely variations of model inputs onto ‘the combined expended uncertainty at 95% confidence level in two-dimensional hydraulic modelling’.
Parametric study of factors influencing the thermal distribution and load-bearing capacity of bonded anchors directly exposed to fire
Authors: Al-Mansouri O , Mege R , Pinoteau N , Lahouar M A , Guillet T , Rémond S 
Published: October 2019

Abstract
Pull-out has been proved to occur more often for bonded anchors under tensile loads at high temperatures than at ambient temperature. The existing evaluation method of bonded anchors under fire only covers steel failure mode. Due to the absence of guidelines for evaluating the pull-out of bonded anchors directly exposed to fire, only the evaluation method for mechanical anchors (without resin) is applicable. This paper presents an experimental study on the influence of different parameters linked to the existing evaluation method by means of pull-out fire tests. Additional unloaded fire investigation tests were conducted to compare different configurations of pull-out fire tests. This paper highlights the level of accuracy of load prediction using the resistance integration method based on temperature profiles of bonded anchors directly exposed to a standard ISO 834 fire. Results showed that parameters such as the existence of metallic fixtures on the rod barely influence the predicted load-bearing capacity and failure time. However, parameters such as adopting concrete element temperature along the thickness instead of steel temperature along the embedment depth, and the existence of insulation around the fixture have a greater influence and may result in a false estimation of the load-bearing capacity and failure time.
