The study area is located in and around Nalgonda town in Nalgonda district, Telangana state. For the detailed investigation of the groundwater condition of a part of this district and covers an area of about 2880 sq.km. in Narkatpalli, Chityal, Katangur, Nakrekaletc. mandals have been selected. Survey of India toposheets on 56 0/4, 0/8, P/1, P/5, Scale - 1: 50,000, IRS ID LISS III satellite imagery using remote sensing and G.I.S. techniques. A detailed study is carried out by classifying the wells into four categories. The groundwater regime with reference to depth water table fluctuation has been evaluated in the study area. The deeper wells mainly occur or observed to occur in the central and southeastern parts of the study area whereas the shallow wells are confined to northern, eastern and southeastern parts of the study area. Also the drainage pattern is observed as medium to coarse textured and dendritic to subdendritic type, which is characteristic of hard rock terrain and develops in regions of homogeneity. The field data provides the information about the depth to water table, and fluctuation of the groundwater. The best suitable areas identified were mainly in shallow valley fill is mostly composed of sandy material, which are generally good to excellent of groundwater prospects. Most of the area posed good groundwater recharge capacity. Based on these studies on lineament density map of the entire study area has been prepared indicating areas of high, moderate and low density lineaments. The important observation is that the deeper wells are having low fluctuation whereas the shallow wells are characterised by high fluctuation and high density lineaments. To study the hydrogeological conditions in the area, field investigations were carried out and 94 wells were inventoried. Groundwater occurs in the study area under water table and semi-confined conditions limited to weathered and fractured zones. The zone of weathering ranges from 0 m (near inselbergs) to 17 m. The joints and fractures, which act as conduits for the movement of groundwater are responsible for the good yield of water from the wells.

Published: April 2019

In many developing countries, tourism is used as a main strategy to achieve greater economic performance. Increased income, both directly and as a result of the multiplier effects of tourism revenues, earnings of foreign exchange, new employment opportunities, access to foreign direct investment and economic diversification are the potential economic benefits of tourism. Statistics on international tourist arrivals in Indonesia showed an upward trend over the past few years and reached the highest number in 2014, recording almost 9.44 million arrivals. The province of North Sumatra is well known as a tourist destination, as well as an economic hub and commercial centre. Indeed, the province was able to attract almost 28% (237,830) of tourist arrivals in 2014, an increase of 4.12 % from 2013. With such a tourist arrivals trend, the tourism sectors has significantly contributed to the economic development of North Sumatera. This paper examined the role of tourism receipts in the short-run economic growth in North Sumatra through error correction method (ECM) from 1986-2014. Econometrics method were used, such as Augmented Dickey-Fuller (ADF) for unit root test, error correction method (ECM) for short run dynamics, and Granger causality test for causal relationships. The standard Granger causality test reveals that there is a unidirectional short-run Granger causality from tourism receipts to economic growth. This study provides evidence to support a tourism-led growth hypothesis in North Sumatra.

A geographically distributed Data center assures Globalization of data and also security for the organizations. The principles for Disaster recovery is also taken into consideration. The above aspects drive business opportunities to companies that own many sites and Cloud Infrastructures with multiple owners. The data centers store very critical and confidential documents that multiple organizations share in the cloud infrastructure. Previously different servers with different Operating systems and software applications were used. As it was difficult to maintain, Servers are consolidated which allows sharing of resources at low of cost maintenance [7]. The availability of documents should be increased and down time should be reduced. Thus workload management becomes a challenging among the data centers distributed geographically. In this paper we focus on different approaches used for workload management in Geo-distributed data centers. The algorithms used and also the challenges involved in different approaches are discussed

Published: April 2019

Background/Objectives: This study examined the effects of introducing programming as a technological tool for teachersâ€™ Technological Pedagogical Content Knowledge (TPACK) development.Methods/Statistical Analysis: Thirty-two teachers were divided into two groups, completing different types of TPACK educational programs. The control groupâ€™s TPACK training program was based on information and communication technology (ICT), while that of the experimental group was based on programming. To verify the effectiveness of the TPACK training program, tests were administered before and after the educational program. A statistical analysis of questionnaire results also investigated changes resulting from TPACK.Findings: Both the control and experimental groups showed statistically significant improvements in the post-test compared with the pre-test. However, in the detailed areas of TPACK by group, the improvements in the two groups differed. Unlike the control group, the experimental group showed a statistically significant improvement in the knowledge related to technology. This result illustrated that programming is effective in solving the problem of integrating technology into the classroom. In contrast, there was no significant difference in the post-test, as this was applied in the short term. However, programming has been shown to affect Technological Pedagogical Knowledge (TPK), Technological Content Knowledge (TCK), and TPACK. In summary, the results showed that a TPACK educational program based on programming is effective for teachersâ€™ TPACK development.Â Keywords: TPACK, In-service teacher, Programming, TPACK-P, Educational program

Published: April 2019

There are number of factors which control the rate of process of natural carbonation and make it very slow in cement based material. Studies show that the effect of carbonation is mostly limited to corrosion of steel reinforcement in R.C.C. structures (including cover depth design and service life prediction). Research at global level is focused on developing a cost effective and safe technology for the possibility of carbon dioxide sequestration as per IPCC guide lines, and attempts are being made to apply the accelerated carbonation technology for CO2 sequestration in concrete. This paper discusses about the detailed study on the uptake quantity of carbon dioxide in concrete, increase of strength and changes in mineral content by adopting. The concrete grades of M15, M20, M25 and M30 were taken for investigating the strength with respect to time of exposure and pressure by adopting Accelerated Carbonation Technology by using commercially available pure CO2 for carbonation curing. After the testing of concrete for strength, XRD analysis was carried out to study the conversion of calcium hydroxide into calcium carbonate due to carbonation. This green technology would help cement, concrete, precast product and other similar manufacturing industries to obtain carbon credit and they can adopt this green technology to reduce their industrial carbon dioxide emissions into the atmosphere to reduce global warming.

Published: April 2019

The torque action provided by combustion engine in conventional vehicles has been boosted by added electric motor, a device which also provide torque, for fuel economy in hybrid electric vehicle. Meanwhile, the complicated nature of combustion engine still poses economic imperatives as petroleum resources are getting depleted. Interestingly, vehicles propelled by electric motor powered by electricity, will completely eliminate combustion engine using fossil oil and also provide clean and reliable vehicles for personal transportation. Since electric motor is a core component, high torque motors are necessary for direct drive application. This papers presents a feasible 24 stator - 10 rotor segments flux switching motor (FSM) using 1 kg weight of PM. FSM is advance form of synchronous machine with double frequency that locates all active materials on the stator only. Permanent magnet (PM) flux source is chosen because it offers loss free excitation without external circuit connection. The JMAG® Studio tool version 14.1 was employed for 2D- FEA design and performance investigation of motor in terms of cogging torque and average torque. Finally, simulation result of proposed motor successfully achieved 352Nm and constant power of 36kW projecting it as viable candidate for high torque necessary for direct drive application.

Authors: Rodi N.S.Noor , Malek M.A. , Ismail A.R. 
Published: April 2019

Nowadays, various algorithms inspired by natural processes have been extensively applied in solving engineering problems. This study proposed Artificial Immune Systems (AIS), a computational approach inspired by the processes of human immune system, as an algorithm to predict future rainfall. This proposed algorithm is another alternative technique as compared to the commonly used Statistical, Stochastic and Artificial Neural Network techniques traditionally use in Hydrology. Rainfall prediction is pertinent in order to solve many hydrological problems. The proposed Clonal Selection Algorithm (CSA) is one of the main algorithms in AIS, which inspired on Clonal selection theory in the immune system of human body that includes selection, hyper mutation, and receptor editing processes. This study proposed algorithm is utilised to predict future monthly rainfall in Peninsular Malaysia. The collected data includes rainfall and other four (4) meteorological parameters from year 1988 to 2017 at four selected meteorological stations. The parameters used in this analysis are humidity, wind speed, temperature and pressure at monthly interval. Four (4) meteorological stations involved are Chuping (north), Subang Jaya(west), Senai (south) and Kota Bharu (west) represented peninsular Malaysia. Based on the results at testing stage, it is found that the trend and peaks of the hydrographs from generated data are approximately similar to the actual historical data. The highest similarity percentage obtained is 91%. The high values of similarity percentage obtained between simulated and actual rainfall data in this study, reinforced the hypothesis that CSA is suitable to be used for prediction of continuous time series data such as monthly rainfall data which highly variable in nature. As a conclusion, the results showed that the proposed Clonal Selection Algorithm is acceptable and stable at all stations.

Published: April 2019

As an autonomous vehicle, Unmanned Aerial Vehicles (UAVs) are subjected to several challenges. One of the challenges is for UAV to be able to avoid collision. Many collision avoidance methods have been proposed to address this issue. Furthermore, in a multi-UAV system, it is also important to address communication issue among UAVs for cooperation and collaboration. This issue can be addressed by setting up an ad-hoc network among UAVs. There is also a need to consider the challenges in the deployment of UAVs, as well as, in the development of collision avoidance methods and the establishment of communication for cooperation and collaboration in a multi-UAV system. In this paper, we present general challenges in the deployment of UAV and comparison of UAV communication services based on its operating frequency. We also present major collision avoidance approaches, and specifically discuss collision avoidance approaches that are suitable for indoor applications. We also present the Flying Ad-hoc Networks (FANET) network architecture, communication and routing protocols for each Open System Interconnection (OSI) communication layers.
