Hybrid Delay Optimization and Workload Assignment in Mobile Edge Cloud Networks  [PDF]
Abdul Rasheed Mahesar, Abdullah Lakhan, Dileep Kumar Sajnani, Irfan Ali Jamali
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104854
Abstract:
Nowadays, the usage of mobile devices is progressively increased. Until, delay sensitive applications (Augmented Reality, Online Banking and 3D Game) are required lower delay while executed in the mobile device. Mobile Cloud Computing provides a rich resource environment to the constrained-resource mobility to run above mentioned applications, but due to long distance between mobile user application and cloud server introduces hybrid delay (i.e., network delay and process delay). To cope with the hybrid delay in mobile cloud computing for delay sensitive applications, we have proposed novel hybrid delay task assignment (HDWA) algorithm. The preliminary objective of the HDWA is to run the application on the cloud server in an efficient way that minimizes the response time of the application. Simulation results show that proposed HDWA has better performance as compared to baseline approaches.

Abstract: In this paper, we are investigating the power consumption of mobile device while performing offloading system. The offloading system is way in which mobile application can be divided into local and remote execution in order to alleviate the CPU energy consumption. However, existing offloading systems do not consider data transfer communication energy while performing mobile offloading system. They have just focused on mobile CPU energy consumption. In this paper, we are investigating the energy consumption mobile CPU and communication energy collaboratively while performing mobile offloading for complex application. To cope up with the above problem, we have proposed Energy Efficient Task Scheduler (EETS) algorithm, whose aim is to determine optimal tasks execution in offloading system in order to minimize mobile CPU and communication energy. Simulation results show that EETS outperforms as compared to baseline approaches.

Abstract: In a traditional Mobile Cloud Computing (MCC), a stream of data produced by mobile users (MUs) is uploaded to the remote cloud for additional processing throughout the Internet. Though, due to long WAN distance it causes high End to End latency. With the intention of minimize the average response time and key constrained Service Delay (network and cloudlet Delay) for mobile users (MUs), offload their workloads to the geographically distributed cloudlets network, we propose the Multi-layer Latency Aware Workload Assignment Strategy (MLAWAS) to allocate MUs workloads into optimal cloudlets, Simulation results demonstrate that MLAWAS earns the minimum average response time as compared with two other existing strategies.
Tamsulosin-induced severe hypotension during general anesthesia: a case report
Dileep Kumar, Fauzia Khan
Journal of Medical Case Reports , 2010, DOI: 10.1186/1752-1947-4-365
Abstract: We report the case of 54-year-old Asian man undergoing elective left thyroid lobectomy. The only medication the patient was taking was tamsulosin 0.4 mg for the past year for BPH. He developed persistent hypotension during the maintenance phase of anesthesia while receiving oxygen, nitrous oxide and 1% isoflurane. The hypotension could have been attributable to a possible interaction between inhalational anesthetic and tamsulosin.Vigilance for unexpected hypotension is important in surgical patients who are treated with selective α1-AR blockers. If hypotension occurs, vasopressors that act directly on adrenergic receptors could be more effective.Tamsulosin (benzenesulfonamide) is a uroselective α1A-adrenergic receptor (α1A-AR) antagonist primarily used for patients with benign prostatic hyperplasia (BPH) presenting with lower urinary tract symptoms [1]. The recommended dose is 0.4 mg or 0.8 mg with a half-life of nine to 15 hours. It is extensively metabolized by the liver.Currently, α1-adrenergic receptor (α1-AR) antagonists are commonly prescribed by physicians as first-line agents to treat BPH, a common condition of aging men. α1-AR antagonists exert their effects by blocking α1-AR-mediated contraction of the prostatic smooth muscle cells and bladder neck [2]. There are three α1-AR subtypes: α1A, α1B and α1D. Terazosin, doxazosin and alfuzosin are α1-AR antagonists that show equal affinity for all α1-AR subtypes [3]. Tamsulosin does not interfere with blood pressure control and has a low potential to cause vasodilation [4]. It is selective for α1A-and α1D-AR subtypes but has less affinity for the α1B subtype.A 54-year-old, 80-kg Asian man was scheduled for left thyroid lobectomy for a thyroid nodule. He was clinically euthyroid with normal thyroid function test results. The patient's medical history was insignificant except for BPH. His New York Heart Association classification was class I. For BPH, he was being treated with tamsulosin 0.4 mg at night for one yea

Dileep Kumar Patel, Tanmoy Som, Sushil Kumar Yadav, Manoj Kumar Singh
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.32028
Abstract: In the present paper, the problem of handwritten character recognition has been tackled with multiresolution technique using discrete wavelet transform (DWT) and Euclidean distance metric (EDM). The technique has been tested and found to be more accurate and faster. Characters is classified into 26 pattern classes based on appropriate properties. Features of the handwritten character images are extracted by DWT used with appropriate level of multiresolution technique, and then each pattern class is characterized by a mean vector. Distances from input pattern vector to all the mean vectors are computed by EDM. Minimum distance determines the class membership of input pattern vector. The proposed method provides good recognition accuracy of 90% for handwritten characters even with fewer samples.
DESIGN OF NOVEL IMPROVED UNITCELL FOR COMPOSITE RIGHT LEFT HANDED TRANSMISSION LINE BASED MICROWAVE CIRCUITS
Dileep Kumar Upadhyay,,Srikanta Pal
International Journal of Engineering Science and Technology , 2011,
Abstract: A novel improved version of unit-cell for the design of composite right left transmission line (CRLH TL) is reported in this paper. Comparative results of both conventional design of unit-cell and proposed design of unitcell for CRLH TLs are presented in this article. The conventional unit-cell is designed based on inter digitalcapacitor (IDC) in series and vias to the ground plane at the stub ends in shunt, whereas proposed unit-cell is designed based on wire bonded interdigital capacitor (WBIDC) in series and vias to the ground plane at the stub ends in shunt . Use of WBIDC in the proposed unit-cell improves high frequency performance by reducing undesired self resonances generated in IDC at lower frequency end. A simple technique is also used in both designs to miniaturize the unit-cell profiles. Dispersion diagrams of the unit-cells show the presence of self resonances in the conventional IDC based unit-cell and absence of such self resonances in the proposed WBIDC based unit-cell, which causes the wider operational frequency band of WBIDC based unit-cell. The performances of both unit-cells are compared from dispersion curve and S - parameters characteristics. The frequency parameter and performance of the both unit-cells are evaluated by full-wave electromagnetic simulator using Ansoft Designer, based on method of moment.

DR Pradeep Kumar,DR Dileep Kumar Verma
National Journal of Medical Research , 2013,
Abstract: Introduction: Coffee is one of the most widely consumed beverages in the world. It is the primary source of caffeine in many populations, but also contains several other biologically active components that may have either harmful or beneficial cardiovascular effects. Caffeine is widely consumed by people of all ages in India as well as many other countries. Methods: The study was conducted on 80 volunteers aged 21-40 years and with body mass index (BMI) between 17.3-28.0 kg /m2 .The subjects were divided into two groups: Control (n=40) (Age less than 25years )and Study group (n=40)(Age > 40 years). Results: Observation suggests that increment in systolic blood pressure (SBP) recorded in both the groups after coffee ingestion, but SBP increment was lesser in elderly person than that of control group. We also observe that there was decrease in heart rate in both study and control group, QTc was lower in control group. Conclusion: Coffee increases systolic and diastolic blood pressure but not the heart rate and the QTc interval. we also conclude that QTc interval is greater in elderly persons.

Physics , 2009, DOI: 10.1103/PhysRevB.81.155402
Abstract: Nanoscale diffusion at the interfaces in multilayers plays a vital role in controlling their physical properties for a variety of applications. In the present work depth-dependent interdiffusion in a Si/Fe/Si trilayer has been studied with sub-nanometer depth resolution, using x ray standing waves. High depth-selectivity of the present technique allows one to measure diffusion at the two interfaces of Fe namely, Fe-on-Si and Si-on-Fe, independently, yielding an intriguing result that Fe diffusivity at the two interfaces is not symmetric. It is faster at the Fe-on-Si interface. While the values of activation energy at the two interfaces are comparable, the main difference is found in the pre-exponent factor suggesting different mechanisms of diffusion at the two interfaces. This apparently counter-intuitive result has been understood in terms of an asymmetric structure of the interfaces as revealed by depth selective conversion electron Mossbauer spectroscopy. A difference in the surface free energies of Fe and Si can lead to such differences in the structure of the two interfaces.

Pakistan Journal of Nutrition , 2010,
Abstract: The study was conducted to evaluate the “effect of chemical preservatives on the shelf life of bread at various temperatures” at the Institute of Food Sciences and Technology, Sindh Agriculture University, Tandojam, in 2008. Two chemical preservatives i.e. calcium propionate (CP) and calcium lactate (CL) at (14±1), (22±1) and ambient temperature (32±2oC) were assessed for their effect on keeping quality of bread. The results conclude that effects of CP and CL at 14, 22 and (32±2oC) were equally significant at (p<0.01) for all chemical characteristics of bread. CP was more effective than CL such as moisture, protein, ash, TSS and carbohydrates were found 37.75 and 36, 9.24 and 8.75, 1.28 and 1.24, 5.10 and 4.71 and 47.75 and 47.01% with CP and CL respectively. Among the storage temperatures, 14oC demonstrate superior performance by increasing shelf life up to a maximum level i.e. 370 h/15.44 days followed by 22oC for 197 h/8.21 days and (32±2oC) for 123 h/5.12 days in decreasing order.
