Cloud computing is a well known computing technology that deals with large capacity of information or data using highly available geographically distributed resources that can be accessed by user via internet in terms of pay per use basis. In such a way, tasks should be scheduled efficiently such that user specified QoS constraints are satisfied. Task scheduling, which is NP-complete problem, plays an important role in cloud computing. In this research work, Big Bang-Big Crunch (BB-BC) technique is used for scheduling of independent tasks in the cloud environment aiming to reduce makespan. The performance of the proposed approach is evaluated by comparing it against GA using CloudSim tool. Experimental results show that the BB-BC approach outperforms GA approach in terms of makespan.

The elliptical non-circular journal profile bearings provides more thermal stability than the circular journal bearings. The present study evaluates the thermal performance parameters such as oil film pressure and temperature experimentally along the circumference of an elliptical journal bearing. The tests have been conducted on the specially designed Journal Bearing Test Rig which is capable of measuring both pressure and temperature simultaneously at nine different locations along the central periphery of the elliptical journal bearing. The experimental data is measured at a constant journal speed=2000 rpm and with a variable radial load ranging from 500 N to 2000 N in steps of 500 N is applied on the bearing. The lubricant used for the experimentation is HYDROL 32. The results shows that both oil film pressure and the temperature increases with the increase in applied radial load on the bearing at the constant speed. Experimentally, two positive pressure loops have been found along the elliptical circumference of the bearing which accounts for better thermal stability as it reduces the cavitation zone inside the bearing.

For the design of finite impulse response (FIR) filter a lot of research has been conducted which involves multi-objective, multi-modal optimization techniques that can be used to calculate the filter impulse response coefficients and try to get the ideal frequency response characteristics. This paper presents evolutionary algorithms for the design of digital FIR filter. Particle swarm optimization (PSO) and differential evolution (DE) algorithms have been applied. Comparison has been done on the basis of magnitude error, ripple magnitudes of both pass band and stop band and maximum stop band attenuation. DE appears to be more promising method for the design of linear phase digital FIR filter especially in the dynamic environment where filter coefficients have to be adapted and convergence speed is of major concern.

Phase detector (PD) and voltage controlled delay line(VCDL) is a main element in delay locked loop (DLL), the power optimized DLL is to generate multiple time/phase delay for different applications such as signal synchronization, VLSI applications and clock and data recovery. The performance of DLL depends upon Locked time, power consumption, time jitter and lock range. The main objective of this research is to design low power consumption, less locked time and less time jitter circuit. Jitter is the randomly variation in the period and phase of the clock signal. In the recent time, increasing the clock frequency, the time period of signal becomes very small due to that amount of jitter can be tolerated. The schematic is designed and simulated in cadence virtuoso analog design environment at 90nm CMOS technology with operating frequency range 100MHz to 1GHz. At 100MHz, the rms jitter with 1V supply is 4.653ps and power consumption is 132.7μW.

Nowadays there is a substantial increase in the use of UAVs in aerospace industries and several diverse applications like defense, disaster management, aerial photography, logistics, etc. and the diversity of applications is proliferating. But the non-linear & continuously time varying dynamics of these UAVs significantly affect the tracking of flight trajectory and thus the designed control system must fortify a robust behavior to the uncertainties and disturbances. This paper, employs the use of multi-objective variant of bat algorithm for the design of fractional order PID controller for the robust flight control of an unmanned aerial vehicle (UAV). The optimization function has been formulated as a mixed sensitivity problem for ensuring robust behavior. As per the results obtained in this paper, the designed FOPID controller ensures good tracking and robustness margins and thus ensure robust response in presence of uncertainties.

Augmented reality is a technology in which computer generated virtual objects interacts with the real time physical objects. Tracking is one of most sensitive issue in augmented reality based system. Without high accurate tracking of physical objects available in real environment, it is not possible to overlay virtual objects. The alignment of virtual and real environment depends upon the accuracy of tracking system. In this paper, we have carried out extensive literature survey of various tracking techniques, such as sensor based, vision and hybrid and limitations of present tracking techniques are discussed. Also proposes to use multiple sensors and camera vision for ubiquitous hybrid tracking system.

Security is the major concern with respect to the critical information shared between the vehicles. Vehicular ad hoc network is a sub class of Mobile ad hoc network in which the vehicles move freely and communicate with each other and with the roadside unit (RSU) as well. Since the nodes are self organized, highly mobile and free to move therefore any nodes can interact with any other node which may or may not be trustworthy. This is the area of concern in the security horizon of VANETs. It is the responsibility of RSU to make the network available all the time to every node for secure communication of critical information. For this, network availability occurs as the major security requirement, which may be exposed to several threats or attacks. The vehicles and the RSU are prone to several security attacks such as masquerading, Sybil attack, alteration attack, Selfish driver attack, etc. Among these Denial of Service attack is the major threat to the availability of network. In order to shelter the VANET from DoS attack we have proposed Enhanced Attacked Packet Detection Algorithm which prohibits the deterioration of the network performance even under this attack. EAPDA not only verify the nodes and detect malicious nodes but also improves the throughput with minimized delay thus enhancing security. The simulation is done using NS2 and the results are compared with earlier done work.

Wireless sensor networks are highly valuable for many location - sensitive applications. Ordinarily, with the location of only a few sensors whose location is already known, localization algorithms work for estimation of remaining sensor positions. In this paper, Flower Pollination (FP) algorithm is used for WSN localization problem. The node's position calculated using FP algorithm is compared with the diverse variants of Particle Swarm Optimization (PSO) algorithm. From the simulation results, it is concluded that the proposed FP algorithm has better localization accuracy and success rate of localized nodes than the PSO variants.

A number of apps currently exist to aid users in finding a better lifestyle or to control their food intake by having better nutritional advice at their fingertips. The mobile nutrition area is widely popular with thousands of people around the world accessing information related to nutrition and wellbeing. However, mobile nutrition apps still can offer more to their users by providing better overall Human Device Interaction (HDI). As nutrition apps are used daily, it is imperative to ensure that users can easily grasp their concept, thus allowing them to quickly understand and receive the information they require to achieve a better lifestyle. The problem lies with HDI elements associated with these apps. This research paper highlights the problems with HDI in mobile nutrition apps through an investigative survey. The questionnaire based quantitative survey was used to understand the patterns associated with mobile HDI in the nutrition landscape and how the user interacts with the mobile app throughout the nutrition tracking process. Respondents clearly showed that the following main problems: difficult to input information into the mobile app, too time consuming to complete, not motivated in any way and also a poor overall user interface. The survey results have enabled us to conclude a number of points that greatly impact the overall HDI of nutrition apps. This was of great importance as it laid the foundations to investigate and explore further opportunities in this area.

Since the inception of Neonatal Intensive Care Units (NICU) many improvements have been done in them time to time to make them safer and better for the infants. DSP processors played an important role in efficient implementation of algorithms, which helped in reducing the noises generated by medical equipment and other external factors. A zone of silence (ZoS) is created in the vicinity of baby's head using different Active Noise Control (ANC) techniques. The focus was on designing an active noise control system, which not only eliminates the noise but also plays the good sounds for the baby along with other tactics that can be helpful in monitoring without disturbing the baby. In this paper various active noise control techniques are reviewed which are developed over the period of time for NICUs. The evolution of new techniques takes place to overcome the earlier problems and pitfalls in designs and implementation, cost effective systems, and different algorithms and techniques used to enhance the quality of noise control.
