In this paper, we propose a model of cloud computing based flood detection and management system (FDMS) using wireless sensor and actor networks (WSANs). Sensors and actors are deployed in connected subnets to localize the problem. As WSANs are limited in terms of resources, e.g., battery, wireless bandwidth and memory, therefore, cloud computing is used to aid WSANs to provide sufficient resources increasing energy efficiency of the system. In the proposed model, sensors are deployed to monitor water level conditions, that is, water in a river or rainfall level. Gateways, which are powerful actors, are used for communication with cloud and for activating actors according to the information processed by cloud. The proposed model is described by the formal technique, Vienna Development Method-Specification Language (VDM-SL) for a detailed level examination, specification and implementation of the system. VDM-SL is used to generate possible test cases to reduce errors and omissions in a system. VDM-SL toolbox is used for validation and verification of the proposed model.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130716201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In canards, configuration point of lift on the wing is behind the centre of gravity of the aircraft. To adjust the characteristic nose down inclination, the canard produces an upward lifting power which opposes weight. It also makes airplane unstable if wind gust increases its angle of attack. In some cases wing lift occurs because of increase in angle of attack. In this work an analytical method has been used to evaluate the pitch damping coefficient for the canard surface of an aircraft. The method is appropriate for a typical aircraft with canard surface. This expression is extracted out by evaluating the moment added to the pitching moment because of the change in the lift of the canard surface. No estimations of physical parameters were useful on the grounds that the primary objective is to find out the expression. The results show that the damping ability is similar as that of the tail. The significance of this particular work is to develop an expression for damping coefficient. The pitch rate causes effective increase in wing angle of the attack resulting in more lift. If the canard's lift is greater than the wing, the nose will pitch further up and hence longitudinal stability of aircraft is more than steady flight condition.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120850822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MC Simulations were carried out in homogeneous and heterogeneous water phantoms with lung equivalent heterogeneities both in presence and absence of bone equivalent heterogeneities. Percentage depth doses (PDDs) were calculated for a) 5×5, b) 10×10, c) 15×15 and d) 20×20 cm2 field sizes with 6 MV photon beam by using IAEA phase space files. For comparison, doses were calculated with the similar phantom geometries using Prowess Panther TPS. The results were found in good agreement with MC results for field sizes of 10×10 cm2 and greater, but deviate in smaller field sizes, especially in presence of heterogeneities. An analysis of average deviation of TPS calculated values from MC values showed that TPS dose calculation is somehow dependent on field sizes, with a severe under-dosage at lower field size and a slight over-dosage as field size increases. The confidence limits (CL) were also calculated for comparison of the two results. For homogeneous phantom, CL decreases with increasing field sizes. For water-lung phantom, initially CL decreases with increasing field sizes but a slight increase is observed afterward. For water-lung-bone phantom, a trend similar to homogeneous water phantom is observed i.e. with an increase in field size, CL reduces.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"341 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132418989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As routing decisions for Mobile Ad hoc Networks has great impact on the overall performance of the network Quality of Service (QoS) parameters (delay, bandwidth, PDR etc.), optimized routing protocols need to be designed. One of the biggest challenges in designing ad hoc routing protocols is to attain the bounded delay and finding the best path/route to the desired node. Ad hoc on-demand Distance Vector (AODV) routing protocol has a single path to the specified node in its routing table without considering various parameters. In this paper, traffic based flooding procedure for AODV protocol is proposed and defined by using formal methods. The procedure states that the data packets generated in the network will first be categorized according to their packet type and then a specific data rate will be assigned for that packet to avoid the redundant overhead on the links. The complete model is designed by using formal methods because formal methods are the most emerging techniques based on mathematics. VDM-SL (formal language/notation) is used to specify the complete and detailed level proposed models' specifications. The procedure is then verified and validated through VDM-SL toolbox1.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132053730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exponential growth in mobile data traffic has led researchers to innovative ideas to cater for these new requirements. At present 4th generation wireless systems are being deployed. In near future, data throughput requirements will even surpass this new technology. Research on 5G has already started where, in addition to other technologies Massive MIMO is considered as a strong candidate to cope with the increased bandwidth requirements. Out of the many important parameters which need to be optimized in Massive MIMO systems, non-linear amplification is an important one. This nonlinearity causes impairments in the transmitted signal. Due to these transceiver impairments, restrictions are imposed on the channel estimation accuracy and the capacity of each user in a Massive MIMO scenario. The effect of hardware impairments is more at the User Equipment (UE), however, in large scale arrays the impact of hardware impairments reduces significantly. Transmit power can be reduced and large hardware impairments can be tolerated by capitalizing on the great degree of freedom offered by Massive MIMO. This allows for the use of energy efficient and inexpensive antenna elements. In this study a signal model that incorporates hardware impairments has been derived based on the RAPP Model of non-linear power amplifiers to analyze effects of hardware impairments on signal propagation in LTE systems.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121199548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes the analysis of aircraft's damping and longitudinal static stability much simpler. For that matter, a model was proposed in which only pure pitching motion was considered and dependence of pitching moment on various factors was sought. A second order differential equation was then formulated in terms of stability derivatives in one variable only. From its characteristic equation, two roots can be obtained whose nature decide the stability of aircraft. The variation of different system parameters such as damping ratio, Z and natural frequency, ran as a function of various flight conditions such as flight velocity and altitude was also studied. Comparing these graphs with the pilot opinion contours, a judgment is passed about the flying qualities of aircraft at the specified conditions. If the aircraft is not safe and easy to handle, a substantial amount of damping should be added to it. Since the stability derivatives are a function of geometric and aerodynamic characteristics of the airplane, designer has some control over longitudinal dynamics by varying different structural parameters, if only that does not cause a subsequent loss in its flight performance. Hence, just by the virtue of second order differential equation, an optimum solution for the performance and handling of aircraft is estimated at different flight conditions.","PeriodicalId":285090,"journal":{"name":"2016 International Conference on Emerging Technologies (ICET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126017352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
