With the rising popularity of WirelessCommunication, Mobile Ad hoc Network (MANET) hasobtained its own place to be analyzed. The potentialapplications of MANET are growing tremendously due to itsrapid changing technology. Wireless network can beestablished in two modes. One is "Ad hoc mode" where thenodes are self-organized and another is "Infrastructuredmode" where the nodes are managed by a central coordinatorsuch as Base Station or Access Point. However, routing plays amajor role in MANET as all the nodes are mobile. MobilityModeling and Control makes the topology of MANET morecomplicated which requires considerable amount of attention.To handle this scenario, different solutions are proposed in theliterature. This paper attempts to evaluate the performance ofthe DSR and AODV routing protocol with different mobilitymodel using NetSim Simulator to extend the applicability ofthe protocol. As of now, much result has not been reported inthe literature with NetSim Simulator and Mobility Modelinghas a great impact on future Internet of Things (IoT). So,performance metrics such as Throughput, End to End delay,Packet Delivery Ratio (PDR), Routing Overhead, and NetworkLifetime has been measured and comparative results arepresented in this paper.

This paper presents a novel programmable direct membership function circuit (DMFC) and complementary membership function circuit (CMFC) that can be used in adaptive fuzzy logic controllers (FLC). The memberships are tunable by varying some voltages on the IC pins. The circuit has a very simple structure and utilizes very less number of transistors. The proposed work presents a three Gaussian membership function DMFC and CMFC that can extend to obtain any number of membership functions as per the requirements. The simulation results are given using SPICE simulator software. The highly accurate and easily tunable characteristics of the proposed membership function circuit make it suitable for embedded system and industrial control applications.

This paper presents a nature inspired heuristic optimization algorithm based on lightning process called the lightning search algorithm (LSA) to solve optimization problems. It is derived from the natural phenomenon of lightning and the process of step leader propagation using the theory of fast particles. Three particle types are established to characterize the transition particles that generate the first step leader population, the space particles that try to become the leader, and the lead particle that represent the particle excited from best positioned step leader. To access the correctness and efficiency of the suggested algorithm, the LSA is verified using a well-used 10 benchmark functions with several characteristics. A comparative study with two other established methods is conducted to confirm and compare the performance of the LSA. The result exhibits that the LSA usually delivers better results compared with the other experimented methods with a high convergence rate.

The readiness and support for self-directed learners in using blended learning is still lacking despite the growing number of innovations and creations for new technologies. Thus, there is a need of empirical study to assess the driving factors of m-learning adoption for the self-directed learners. The main objective of this exploratory study is to investigate the relationship of the factors that motivate m-learning adoption among self-directed learners. The method involved questionnaires survey with 190 respondents from April to May 2015. There are four (4) variables have been covered in this study such as Perceived Near-term usefulness, Perceived Ease of Use, Personal Innovativeness, and Perceived Long-term Usefulness. The collected data is then analysed using Spearman's Rank Order Correlation analysis. The results indicate that the strongest relationship is the relationship between Perceived Near-term Usefulness and Perceived Ease of Use [r=.603, n=190, p<;.000]. Future work may involves empirical investigation with other case of blendedlearning methods such as webinars, virtual classroom, social learning (e.g. wikis, discussion forums), access to on-demand learning resources and self-paced e-learning.

In this study, we have proposed an improved anti-windup control using a Proportional-Integral (PI) controller. PI control has been widely used for the industrial applications. However, PI controller is usually designed in a linear region ignoring the saturation-type nonlinearity. An anti-windup control comprises a linear feedback controller that satisfies the desired non-saturation specification and an anti-windup compensator that operates during the saturation. This control method prevents large overshoots caused by the windup phenomenon. However, since the controlled plant is not type-1, steady-state errors can occur and the input to the integral action is limited. To avoid these problems, we transformed the controlled system into a type-1 plant. Therefore, no steady-state errors occur when using a type-0 plant and the output converges to the target value.

For any real-time application, detection and tracking of features becomes very important. The detection and tracking algorithms have to be very robust and efficient with least or zero false positives and false negatives. We use a novel combination for detection and tracking purpose. In this paper we propose a robust mouth region extraction and tracking algorithm that works in real-time. The region of interest for our application requires the face and mouth regions. We propose a novel technique for extracting the mouth region automatically. The proposed technique detects and tracks the mouth in either closed or opened state. We use the color components for skin tone and lips extraction.

Today, Digital Prototyping and simulation technologies are used in the development of new technical systems and widely applied in research and industry. They allow cost- and time-efficient tests in all stages of development and support decision making. The sensor simulation component represents an important aspect in many simulation scenarios, especially in robotic applications. This paper focuses on the modelling and simulation of a laser scanner with adjustable pattern and is motivated by the development of a space qualified 3d laser scanner system for autonomous orbital rendezvous and docking. It continues work on a single ray based 2d laser scanner simulation for localization and mapping of mobile robots on planetary surfaces.

The idea of particle swarm optimization falls under the domain of swarm intelligence. Particle swarm optimization technique is widely used for finding the global minima of well-known benchmark functions. The main idea behind this technique is that working in a group improves the performance of a system. A modified particle swarm optimization technique is proposed in this paper and tested on seven standard benchmark functions. The two major modifications are introduced in the standard particle swarm optimization, modify the velocity of a particle such that the particle remains within the confine limits of clamp velocity, and penalize the particle velocity, if the sum of the velocity vector and position vector results in breaching the boundary limits of search space. The results of the modified PSO are compared with the two versions of standard PSO, constant inertial weight with no velocity clamping and linearly decreasing inertial weight with no velocity clamping.

This paper investigates the effect of feature parameters on the objective assessment of stress under indoor noise conditions. To this end, both a qualitative stress parameter and quantitative feature parameters are collected according to different sequences of indoor noises. In other words, the qualitative stress parameter is obtained by continuously logging the perceptual intensity of stress for a certain period with a score ranging from 1 to 10 under indoor noise conditions. In addition, the quantitative feature parameters are represented by the combination of various audio feature parameters consisting of psychoacoustic, spectral, and temporal features. Finally, multiple linear regression analysis is conducted on the pairs of the qualitative stress parameter and possible combinations of quantitative feature parameters. It is shown from the evaluation that combinations of feature parameters could have a coefficient of determination of up to 0.9607.
