Title: Effect of using construction and fence BRC layers on clayey silt CBR values
Author (s): Qassun S. Mohammed Shafiqu and Azhar Sadiq Yasun
Abstract:

California bearing ratio (CBR) for natural fine soils has wide range values approximately from 1.5 to 40%, and according to Iraqi specification (SOBR R5) CBR values should not be less than 5%. Many studies use geogrid and geotextile meshes as layers and others use hair fiber, waste plastic strip, jute fiber, fly ash and crushed waste glass to improve CBR value of weak fill soil layers generally. This study motivated to use new method approach for improving CBR value of weak clay soils by using available not expansive fence BRC mesh and normal construction BRC. Several trails has been conducted to construct soil CBR sample with single and double BRC meshes layer with different mesh sections to note the effect of using these meshes on soil CBR value, the distribution of meshes was constructing depending on sample height. Studying the effect of using BRC meshes on soil penetration has been also conducted in order to measure the prepared natural soil behavior during loading process. Results shows that CBR improvement ratio is increased when the CBR value depends on (7.5mm) penetration and recorded lower values if the CBR value depends on 2.5 and 5mm penetration. The maximum improvement ratio was about 2 when the sample reinforced with double two layers of normal construction (BRC).

Author (s): Kotok V. A., Kovalenko V. L., Kovalenko P. V., Solovov V. A., Deabate S., Mehdi A., Bantignies J. L. and Henn F.
Abstract:

Electrochromic nickel hydroxide film has been prepared for the first time, using electrochemical template synthesis with polyvinyl alcohol (PVA) as template. Such advanced Ni(OH)2/PVA composite film has improved adhesion to substrate and can be potentially used for manufacturing flexible electrochromic devices. Films obtained by template cathodic deposition can be stored in a dry state without morphological changes which allows for optimization of manufacturing of complete devices. The optimal concentration of polyvinyl in electrodeposition solution has been found 5% wt. It has been demonstrated that polyvinyl forms nanosized 3-D matrix on substrate surface which promotes formation of X-ray amorphous nickel hydroxide and is incorporated into the film. It has been established, that at optimal current density 0.625 mA/cm2 the deposition rate is 3.87µm/h. By simultaneously recording cyclic voltammogramms and colorization curves high electrochemical and optical properties of films prepared using template synthesis with PVA have been demonstrated, with coloration degree of up to 80%. Significant effect of drying temperature on electrochemical and optical properties of Ni(OH)2/PVA composite films has been demonstrated. Low drying temperature (20°) results in films with high electrochemical activity and coloration degree. At 90° ? a drop in colorization degree has been observed.

Title: Destruction of rock upon blasting of explosive agent
Author (s): Sergey Antonovich Vokhmin, Georgij Sergeevich Kurchin, Aleksandr Konstantinovich Kirsanov, Andrey Olegovich Shigin and Anna Aleksandrovna Shigina
Abstract:

In order to provide the most efficient indices of development of underground excavations the main attention is paid to blasting operations, namely, to determination of optimum parameters of drilling and blasting operations. Development of new and reconstruction of existing mines require for extended scope of excavating works, their length can reach some tens of kilometers. Up till now excavations at most of mines are developed using drilling and blasting operations. Improvement of drilling and blasting operations is one of trends to increase efficiency of excavation development. Reliability extent of calculated parameters of drilling and blasting operations can influence on technical and economical performances of excavation development. At present numerous existing procedures are empiric dependencies, they are based on primary determination of specific consumption of explosive. The main drawback of such procedures is the application of coefficients of specific consumption, which vary in wide range, their values depend on the qualification of experts who perform such calculations. As a consequence, the parameters of drilling and blasting operations are set on the basis of averaged values, which impair efficiency of blasting operations. We believe that calculations of parameters of drilling and blasting operations should account for the most complete range of factors playing important role in impact of blasting energy on destructing massif. In addition, the proposed engineering approach should enable improvement of efficiency of blasting operations with desirable decrease in material and non-material expenditures. This work describes briefly tock destruction by blasting of explosives, highlights main factors influencing on efficiency of drilling and blasting operations upon development of excavations. The work analyzes calculation procedures of main performances of drilling and blasting operations, recommendations are given for development of pattern of drilling and blasting operations on the basis of calculation of destruction zones of rock massif.

Title: Improvement of palm oil biodiesel properties using ethanol as an additive and its effect on diesel engine performance, combustion and emissions
Author (s): S. Madiwale, A. Karthikeyan, V. Bhojwani and M. Dombale
Abstract:

As we need an alternating fuel that will replace diesel fuel in order to reduce the harmful emissions coming out of engine as exhaust by products, which necessitates the improvement in engine performance and increase in combustion characteristics of fuels in the combustion chamber. As biodiesels are having high viscosity and higher flashpoint than diesel, it will be difficult to use biodiesel as a fuel alone in present diesel engines. Hence it is preferred to blend biodiesel with diesel to get required properties of blend that will suit the present diesel engines. But higher kinematic viscosity of biodiesel/diesel blends as compared to diesel affects the atomization of fuel in the combustion chamber which further reduces the combustion pressure and temperature and reduces the power output of the engine. This necessitates the addition of ethanol as an additive in the blends which further enhances the hot flow, cold flow and thermo-physical properties of the biodiesel/diesel blends. Therefore in this study feedstock of palm oil biodiesel is used as fuel with 5% ethanol by volume as an additive in the blends of palm oil biodiesel/diesel blends. Hot flow and cold flow properties of blends of palm oil biodiesel/ethanol/diesel blends are experimentally investigated as per IS 1448 standards. Investigation outcome shows that ethanol as an additive improves the kinematic viscosity of blends of palm oil biodiesel/diesel by 4% lesser than biodiesel/diesel blend without ethanol and 12% higher than diesel. But on the other hand calorific value of the blends with the addition of ethanol decreases calorific value by 6.27% than biodiesel/diesel blend without ethanol and 6.87 % than diesel. Most importantly the cold flow properties are enhanced by the addition of ethanol in the blend such as cloud point increases by 13 % than biodiesel/diesel blend without ethanol and pour point increases by 14% than biodiesel/diesel blend without ethanol. The combustion and performance analysis are improved with the addition of ethanol and decreases the harmful emissions from the exhaust manifold of the engine. The effect of ethanol as an additive in the blends of palm oil biodiesel/diesel blend on properties, performance, and combustion and on emissions are studied in this paper.

Title: Performance analysis of handover strategy in femtocell network by using Fractional Frequency Reuse and Dynamic Power Control methods
Author (s): Azita Laily Yusof, Mastura Rosdi, Norsuzila Ya’acob and Nur Idora Abd. Razak
Abstract:

In Long Term Evolution (LTE) network, a femtocell as known as Home Evolve Node B (HeNB) is a small base station that aims for indoor usage such as at home or enterprise in order to fulfill the upcoming demand of high data rates. It is very user deployed so it reduces operations cost for mobile operators, and at the same time provide a high user experiences to users. However, femtocell deployments caused interference between femtocells itself and also to the existing macrocells due to sharing the same frequency band between macrocell and femtocell. In order to achieve a high network capacity and a good user experience, more advanced interference coordination and radio resource management schemes would be required as compared to the conventional cellular network. Hence, the interference management methods which the are Fractional Frequency Reuse (FFR) and the Dynamic Power Control (DPC) were proposed. This paper analyzed on the performance analysis of handover strategy in macrocell and femtocell networks for balancing the network User Equipment (UE) by offload traffic from macrocell to the femtocell and hence the high load balancing of UE network can be achieved and then minimize the interference occurrence in the network by using the proposed methods. The simulation results showed that the proposed combining methods give a significant reduction of number of handovers and inter-cell interference in LTE HetNets by offloading the macrocells traffic to the femtocells and higher load balancing performance can be achieved.

Author (s): Chandrasekharan Nataraj, Sheroz Khan, Mohammed Hadi Habaebi and Asan G. A. Muthalif
Abstract:

A basic analysis of inductive coils and its parameter calculations are presented. The simulations of mutual inductance, coupling factor calculations are demonstrated with graphical analysis. Three different lab-scale coil models such as square, circular and rectangular coils are wounded to evaluate the magnetic field by experiment, to validate the performance of Wireless Power System (WPT). In the open literature, circular coils are employed in most of the works, but lessworks were shown in the parameter analysis. Further investigations on parameter exploration seems as a prerequisite for magnetic field measurement by estimating the parameters such as mutual inductance (M), coupling factor( k), magnetic flux (F) and magnetic field (B). It helps us to select the coils according to the applications. In this work, it is observed that circular performs well than other shaped coils in terms of parametrical analysis which are mentioned above. The simulation, and experimental results are tabulated as well as supported graphical plots are shown as proving circular coils performs well in the WPT scenario.

Title: Methodology to reduce vampire power using PIC microcontroller
Author (s): Anup Kumar, K. Fathima, T. Mary Saranya and S. Hema
Abstract:

In the rapidly developing world, energy saving has become one of the major aspect in day-to-day’s life. For an efficient energy saving, all parts of the world are working in all possible ways to avoid the energy crisis in order to conserve it for the future generation. Among the various sources of energy crisis, vampire power plays a major role. Most of us are not aware that the electrical device consumes power even when they are in standby or sleep mode. Those are the power which must be paid as tariff to the government. In olden days, vampire power was not taken into account since they did not contribute much to the wastage of energy. But now-a-days, due to the invention and introduction of many advanced electrical and electronic equipment, there is a large amount of wastage of energy due to vampire power which must be taken into account. It contributes to about 20W of the total energy supplied at our residents. This rating depends on the type and model of the appliance used. So, our project proposes a system that controls the vampire power using a microcontroller depending on the relation within the different home appliances and the user’s behavior with the devices, thereby saving the energy benefiting a safer future and reducing the tariffs of electricity bills.

Author (s): Vydeki Dharmar, Bhuvaneswaran Raghuve and Subramanian
Abstract:

Blackhole attack is considered to be a virulent attack in mobile Ad Hoc networks (MANETs) that operate on reactive routing protocols. This paper presents an efficient cross layer approach to detect the malicious node that launches the blackhole attack. The proposed scheme uses Adaptive Neuro- Fuzzy Inference System (ANFIS), which combines the benefits of neural networks and fuzzy logic, in the detection process. Experimental results prove that the cross layer approach using ANFIS outperforms the scheme using single layer approach. The proposed scheme produces 100% true detection when Fuzzy C-means (FCM) clustering is used and 95.9% for subtractive clustering. The detection time has also been comparatively reduced.

Title: Charger monitoring stream analysis using artificial neural networks
Author (s): Junghoon Lee and Gyung-Leen Park
Abstract:

This paper develops a trace and prediction model for the energy load imposed by electric vehicle charging in Jeju City, based on artificial neural networks as well as the massive amount of charger monitoring streams collected for about 1 year. The monitoring system generates a data archive, in which a single report essentially embraces charger ID, timestamp, and battery level reading. Our data analysis module, consisting of MySQL, R, and C program implementation across Linux and Windows PC domains, not only processes raw data files to insert into a database table but also finds the active charger set. The distributions of the number of reports and the power consumption for each charger are investigated. For the day-by-day power consumption stream for vehicle charging, a neural network model traces and predicts the time series having 124 sequential values. The experiment result shows that our model catches up with unpredictable spikes just with small time lag.

Title: Centralized clustering algorithm to enhance energy consumption in Wreless Sensor Networks
Author (s): Mustafa Fuad Ismail and Dahlila Putri Dahnil
Abstract:

A Wireless Sensor Networks (WSNs) composed of a large number of sensor nodes within a sensing geographical area. Energy consumption is considered a major WSNs issue. Therefore, a considerable number of researches have investigated various ways to reduce energy consumption. One of the best techniques used to reduce energy consumption is clustering. Clustering helps to improve the network performance through extending the battery lifetime. Our study improves the work on LEACH Enhancements for WSNs based on the energy model by introducing the K-means clustering approach to improve energy and increase network lifespan. The proposed approach divides the nodes into member nodes and cluster head nodes. The member nodes transmit data to the cluster head, whereas, the cluster head nodes are responsible for communication with the base station. This approach is a centralized election technique where the base station makes the decision for selecting the cluster heads based on the information received from each node. The advantage of the proposed technique is that the information of each node is only sent once to the base station during the initialization phase. The base station performs weightage calculation for all nodes and nodes with the highest weights are elected as cluster heads. The base station also decides the cluster members and the decisions are then transmitted to all nodes in the network. This research introduces weightage calculation based on three important parameters which are remaining energy, number of neighbor nodes and the node’s distance to base station. The proposed technique consists of three phases: Initialization Phase, Setup Phase, and Selection Phase. The results of our proposed technique shows significant improvement of the residual energy, the total energy consumption, the total alive nodes, and total packets delivered compared to LEACH Enhancement for WSNs based on the energy model technique. In conclusion, the results of this study show improvements and achieved the objectives of this paper.

Title: Eye tracking electronic wheelchair for physically challenged person
Author (s): Chee F. P., Duinong M., Chang H. W. J., Awang A., Francis A. S. and Dayou J.
Abstract:

A robotic wheelchair with novel ideas which integrates three different options to all kinds of impairment as well as disabilities was designed in this project. The first option allows users that are not capable of moving their limbs, to navigate the wheelchair using their eye, namely the optical detector. The optical detector allows user that suffers severe disability such as amyotrophic lateral sclerosis (ALS) that paralyzes the victim mobility entirely to move by moving their eye to desired location. The secondary option provides common wheelchair users who are suffering from less severe disability to navigate using a touch input option which is accessible via their smart phones, namely touch and go APP. The touch and go APP can be controlled easily as well as adjusting the speed of the wheelchair. The third option works for users with limited mobility by using a voice command application. In addition, the robotic wheelchair is integrated with multiple safety features, an ultrasonic sensor and dual bump sensor. The ultrasonic sensor is to create a threshold distance between the user and obstacle in front and to prevent collision. The bump sensor works as a failsafe, where an object that is in contact with it will reverse the robotic wheelchair to a safe distance. This research combines both ease of access navigational technology with a safety features to help those who are in need of such technology to move with a high safety element. The newly designed wheelchair does not discriminate any kinds of disabilities with the integration of the three navigational options.

Author (s): Rini Novrianti Sutardjo Tui, Aryanti Virtanti Anas and Nur Fitriani
Abstract:

Production and cost planning were several important things to be considered in making decisions for development of a company production. Revenues from production process of lateritic nickel ore mining in PT. ANTAM (Persero) Tbk, UBPN Sultra last few years only provided profit that did not reach the company’s target. The costs greatly affected economics of production and corporate profits, one of which was the cost of procurement of heavy equipment. The company was still using heavy equipment leasing services to carry out production activities. Based on these problems, it was necessary to do an analysis about production and decision making procurement of heavy equipment with a lease-purchase alternative for year 2016 to 2020. The data used were costs, data company's production and price data from factors that affected the heavy equipments operation. Production was analyzed by using breakeven point analysis, whereas for deciding on leasing or purchasing was using incremental analysis and sensitivity analysis. Based on data processing and analysis, it was indicated that laterite nickel ore production in 2012-2015 would still be in a state of breakeven. Estimation results of production in 2016-2020 to maintain the safety limit production showed that production of nickel laterite ore would also still be in the breakeven point. Based on the analysis of incremental and sensitivity, when the heavy equipments lifetime lasted for five years, the procurement of heavy equipment by purchasing was more efficient compared to the lease option.

Author (s): Gnana Kirubaharan V., Elumalai P. S. G. and Yovan Felix A.
Abstract:

Online shopping is the trend nowadays; there has been an increasing demand for easy analysis of the many consumer reviews posted in the internet. The more number of reviews there are about a product, the more difficult it becomes for consumers to navigate through the reviews to arrive at an informed decision about the product. We propose a product feature ranking framework, which automatically identifies the important aspects of products from online consumer reviews, aiming at improving the usability of the various reviews. The important product aspects are the specifications that are frequently commented on by the masses. The more frequent an aspect is mentioned, the more important it is to increase the overall opinion of the product by document level classification and extractive review summarization.

Title: Disease predictive, best drug: Big data implementation of drug query with disease prediction, side effects and feedback analysis
Author (s): Sathish S. and Usha Nandhini
Abstract:

Nowadays medicine consuming has become day to day activities for the people who were suffering from diseases. Hence many of the people are not aware of the medicine which is prescribed by doctors or pharmacies. Once they are affected by diseases they are approaching doctor and they are in taking the medicines prescribed by them, without having any knowledge about it and gets affected by its side effects. Due to the advancement in medical field many different approach are proposed about using medicines. Many medicines are available for one disease in which some causes side effects. Some patients have an side effect in which the medicine causes same side effects which results in increase in disease. My proposed system is that first we will identify the disease based on patient symptoms and do analysis in that and we will predict disease and suggest the best tablet which do not causes side effects by doing analysis on trained sets based on patient positive improvement and sort the best medicine in ascending order and suggest the medicine to patient, if the patient has some side effects in that top order medicine, next medicine is prescribed and we make appointment for good and best available doctors and book an appointment for that patient.

Title: Energy-aware for DH-AODV routing protocol in Wireless Mesh Network
Author (s): Yousif Ali Saadi, Rosilah Hassan and Dahlila Putri Dahnil
Abstract:

Wireless Mesh Networks (WMNs) can be the key technology for the future of wireless networks. However, WMNs implementation still has many issues to be resolved especially on finding the best path to forward information. According to many researches, one of the most important component in WMNs is the routing protocol and how to make it efficient in performing the requirements of WMNs. Directional Hierarchical Ad-hoc On-demand Distance Vector (DH-AODV) routing protocol, proposed to enhances Ad-hoc On-demand Distance Vector (AODV) routing protocol for WMNs. DH-AODV is performing well for WMN, but in this routing protocol no mechanism is considered to deal with the energy consumption of the nodes in the network. Therefore, in this paper we propose an Energy-aware DH-AODV (E-DH-AODV) routing protocol to select a path toward a gateway based on the energy balance. Furthermore, E-DH-AODV can reduce the number of broadcasting route request (RREQ) packets, by sending these packets toward the gateway considering the nodes with less hop-count only. The simulation results shows that E-DH-AODV can reduce the energy variance consumption by 10%, increase the packet delivery ratio (PDR) by 9%, and reduce the overhead by 5% in comparison with DH-AODV.

Title: Effects of dual versus super single truck tire on flexible pavement performance: A mechanistic approach
Author (s): Ahmad M. Abu Abdo
Abstract:

With the widely observed premature failures of flexible pavements, attentions have been directed to changes on heavy vehicles loads, axles configurations, and tire types and pressure as a cause for such phenomenon. Super single (wide-base) tires were introduced in early 1980s as a replacement to traditional dual tires, and considered beneficial to the transportation industries. However, this type of tires proved to cause more damage to flexible pavements. Recently, new generation of super single tires were developed with a promise that the damage issue was addressed. Many studies were conducted but were in disagreements in their findings. Thus, this study was conducted. 3D Move Analysis software was used to conduct analytical evaluation and compare both tire configurations by utilizing existing project and actual materials test data. Results showed that when compared to dual tires, super single tire induced less normal stresses in the analyzed flexible pavement by 28% in the z direction and 45% in the y direction and 47% in the x direction. Therefore and as per the results of the analysis, super single tires would inflect less percentage of bottom up cracking in the asphalt concrete layer and less permanent deformation in all pavement layers.

Title: Water and glycol coolants in the autonomous heat supply
Author (s): Pavel Aleksandrovich Khavanov and Anatoly Sergeevich Chulenyov
Abstract:

The solution to the problem of defrosting in the autonomous systems of heat supply in cases of an accidental power outage is often solved by replacing the water in the "freezing" of heat carriers, which include the water-glycol mixture. However, it must be borne in mind that the water-glycol fluids can lead to significant violations of the mode of operation of the heating system, which may lead to a decrease of heat transfer and the ingress of air into the system, as well as boiler malfunction that could lead to a decrease in performance or damage to the heating surfaces due to the formation of domestic deposits. In this study reviewed and analyzed thermal and hydraulic features of water-glycol (WG), water-ethylene-glycol (WEG) and water-propylene-glycol (WPG) coolants autonomous heating systems of various types. Analyzed the cost comparison, coolant system pressure losses and the principle choice of the volume of the expansion vessel.

Title: A system to optimize glucose tests in the hospitals of Huila department in Colombia
Author (s): Albeiro Cortes Cabezas and Jose de Jesus Salgado Patron
Abstract:

Nowadays many health centers in the world have robust hospital information systems capable of storing and processing the collected data of all type of variables associated to the different medical and laboratory tests that are made to the users of the service. A hospital information system enables the integrity and readability of patient information to be guaranteed. In addition, it makes it possible for such information to be available at the point of care where the patient is, independently of the institution providing health services where it is attended. Unfortunately, hospitals in Huila do not yet have an adequate information system, so that old-fashioned, complex and unstructured methods are used, such as handwriting the results of tests performed in paper formats, which are then examined and analyzed by the attending physician and then make the relevant decisions. In this project, an information system was implemented to optimize the process of glucose testing (glucometry) in hospitals in Huila to improve the organization of data, making access much more comfortable. The HL7 standard set was used as a guide for good interoperability and to make the system scalable. Access can be made through a mobile application, which was developed using Android Studio or through a website. The information system allows access to the data of a specific patient and also has the option of graphing them to observe the evolution of glucose levels over time and thus provide the appropriate treatments for each case.

Title: On the conversion of automotive engines for general aviation
Author (s): Luca Piancastelli and Stefano Cassani
Abstract:

Automotive engines have outstanding quality controls and extremely high cost-effectiveness. This is typical to lean, mass production. For this reason, the application of these engines on aircraft is most appealing. Ultralight-sport aircraft have pioneered this approach. A few automotive-aircraft certified engines are already available on the market. However, this approach has not been as successful as foresaw a few years ago. This is due to the differences between the automotive application and the aircraft use. These differences have lead to teething problems that have been solved in almost 20 years of research work. The level now reached and the experience achieved makes it possible to convert any "successful" automotive engine into an aircraft engine. This work starts with the description of the data available from automotive manufacturers. Automotive engines have a huge background of statistical data on performance, reliability and TBO (Time between Overhaul). The correlation of these data to an aircraft application is not straightforward. Then the performance curves obtainable from the new aircraft engine are introduced. Finally, an algorithm calculates the residual life to TBO (Time between Overhaul) of an automotive engine. The method was tested on a few small last-generation CRDIDs (Common Rail Direct Injection Diesels) and spark ignition (gasoline) engines. These engines were also converted for use into small aircrafts with power ranging from 60 to 200HP. This very simple method is implemented directly in the FADEC (Full Authority Digital Electronic Control) or E-ECU (Engine Electronic Control Unit) of the engine with very few lines of C-Code (C-Language Code). It is assumed that the engine undergoes regular maintenance schedule and OBD (On Board Diagnostic) is implemented. OBD is perfectly able to foresee the imminent failure of the accessories like the starting motor, the generator, the turbocharger, the injector's, the HPP (High Pressure Pump), etc. These parts are external to the engine and can be changed during field maintenance. Accidents, like prolonged under/overcooling, crankshaft damper failure, over speed are monitored by the OBD and require specific maintenance actions. Ordinary problems like excessive fuel, lubricant, coolant consumption, pressures out of range... are also dealt by the OBD-related service system.
