Abstract:

Spectral and spatial two-dimensional optical code division multiple access (2D-OCDMA) systems cannot support low cost passive optical networks (PON) due to the extensive use of optical fiber media. Consequently, spectral and temporal OCDMA systems are explored to provide the required system capacity. Maintaining an efficient cross correlation values between the adjacent codes is of primal importance to ensure required system capacity at relatively simple architecture. To develop such a system this paper focuses on the design of a 2D spectral and temporal OCDMA coding scheme. The proposed scheme mitigates the effect of interfering users by utilizing fixed in phase cross correlation code called diagonal eigenvalue unity (DEU) code along the spectral domain; whereas zero cross correlation (ZCC) code is adapted at the temporal domain. Analysis shows that the proposed combination significantly mitigates the contribution of interfering users and reduce the impact of cross correlation. This can lead to a system with relatively high transmission capacity and simple architecture for implementation at the cost sensitive access domain.

Abstract:

This paper is about the technique used for removal of ECG Signals Artifacts Using Multistage Adaptive Filtering. Electrocardiogram (ECG) is the diagnostic tool to monitor rhythm of heart activity. it is of low amplitude and contain numerous noise which includes power line interference, baseline drift , movement artifacts and electrosurgical noise. For better diagnostic and treatment of cardiac patient the removal of such noise are very much important. Initially various method were proposed to remove the artifacts for better understanding of cardiac problem. These were static or fixed filters i.e. Band pass Low pass or High pass which based on the nature of the noise. The static filters possess fixed filter coefficients which makes it strenuous to eliminate time varying noise from the signals. To overcome this shortcoming of the fixed filters, various adaptive filtering procedures have been introduced. Since the ECG signal suffers from several artifacts at a time, which makes a single stage adaptive filter unsuitable for multiple noise signals removal. This paper presents a Multistage Modified Normalized Least Mean Square (MNLMS) algorithm for the eradication of multiple artifacts from signals of ECG. The results of the suggested algorithm are compared with existing adaptive algorithms including Multistage LMS,MNLS ,CNN,DNN including Signal to Noise ratio (SNR), convergence rate as well as the computational time, which elaborate the effectiveness of the suggested algorithm. After the removal of noise, db’6 wavelets are used for the detection of features (PQRST) of ECG wave because wavelet tree offers a very good time-frequency resolution analysis which is not possible with the Fourier transform.

Abstract:

Climate change is variation in patterns of weather that lasts from decades to centuries. The increasing levels greenhouse gases are playing key role in producing global warming and it has decisive impact on hydrological cycle of earth. The resulting temporal and spatial availability of water makes it imperative to exercise innovative way of water conservation strategy .In this study ground water rehabilitation strategy is proposed for groundwater recharge using excess storm water to be injected in recharge wells at Narai Khuwar. The current groundwater levels of tube wells and well logs of Hayatabad were obtained from Peshawar Development Authority for over 70 tube wells. The hydrological study has been performed using rainfall-runoff model WIN TR 20 by using rainfall data of last 40 years and other hydrological and hydro-geological parameters. The UHG of different time intervals (2 to 200 years) were obtained to determine the availability of water. The subsurface geology was determined by conducting resistivity test. Extensive numerical modeling was performed for current and future water levels in these wells using MODFLOW. The calibrated model was then used in simulation mode and an estimate of water levels in the study area was made for 30 years (2019 - 2049) with and without application of proposed recharge strategy. The study indicates that mitigation measures are required to arrest the rapid water decline in Hayatabad.

Abstract:

Rainfall is an extrinsic factor for the collapse of sloping terrain in Western Ghats of Kerala. Careful analysis of rainfall induced landslide is very important as people in the area have serious threat from landslides. In-depth assessments of variation of pore water pressure change in slopes during avalanche rainfalls are required for the purpose of mitigation. Soil water characteristic curve was prepared by field and laboratory tests so that various properties of unsaturated soil could be estimated. As suction distribution and rainfall infiltration were influenced by the ratio of rainfall intensity to saturated hydraulic conductivity, numerical models were analysed for various ratio of rainfall intensities. Variations of pore water pressure across different sections of the slope and reduction of factor of safety with respect to time and rainfall intensities were analysed. The results of the analyses can be applied in practice for determining the probability of landslide hazards in areas vulnerable to heavy rainfall and consequently damage from landslides.

Abstract:

The problem of mining numerical data and to propose different approaches to efficiently apply clustering to such data According to an aspect of the method the Mean Base Divisive Clustering (MB-DivClues) method is developed to categories unstructured data into various groups. The a constructive mean-based divisive clustering method is developed to reduce comparison includes several steps which includes identification of mean value from a given dataset, to find the arithmetic mean value of base cluster-infrequent attribute and storing the found mean value in a tree which is represented as root. Further the steps include comparing the objects in the dataset with the said mean value and stored in the nearest cluster. A new cluster is created to place the sorted object in new cluster. In the process of proposed method includes steps of shifting the object value to the left cluster when it is less than the mean value, shifting the object value to right cluster when it is greater than the mean value and repeating the above procedure until singleton cluster is picked from the given dataset. Wherein before applying divisive Clustering method, initially all the data objects are available in a single cluster and a mean value is calculated on the dataset.

Abstract:

Designing an efficient power distribution network is a major challenge in modern day system-on-chip. During manufacturing, the signal integrity problems such as resistive voltage drop, inductive noise at pad locations and electro-migration may result silicon failures. This paper deals with the analysis of supply noise using multiple power supply and use of decoupling capacitors for reduction of supply noise. In this work flower pollination algorithm has been used for decap estimation so that the supply noise can be reduced significantly and various design parameters remains at its best. The purpose of this work is to reduce the supply noise with effecting the other design parameters of the chip. In this work the supply noise has been reduced upto 70.2% with reduction of 81.6% in power consumption and 17.07 % increment in delay parameters. This approach can be used for any system-on-chip.

Abstract:

Due to significant demand on electrical energy on residence sector, especially those spend on space cooling for extreme hot summer countries in the middle east; moreover, the national electrical shortage supply issue in Iraq, it is a kind of interested and challenge at the same time to research for solution and utilize the redundancy of solar energy in such region. A test room was constructed 4.7*2.5*2.85m subjected to solar radiation all day time situated in Baghdad, a bunch of experimental testes were conducted for parametric study over summer season from April till October, the experiment testes were recurrent on monthly basis. The roof of test room was cooled by circulated water in pipes, the water is pre-cooled by evaporative cooler in separate system whilst the relatively cooled air is blew towards the A/C outdoor unit and other stream directed on back side of solar panels to minimize its average temperature for promoting performance aspects. Results indicated the energy save 33.53% over entire season when cooling the roof by water circulation and 9.01% energy saved due to A/C COP enhanced from cooling the condenser by cold air. Therefore COP was enhanced due to cold air effect from 2.90 to 3.39The solar panel temperature was minimized about 11°C that results to enhance the efficiency of PV panels from 12.1% to 12.8 %, solar system can handle the operation for 3hrs peak time when A/C is off as more energy was saved.

Abstract:

A blockchain technology is one of the types of decentralized technology and is based on distributed ledger technology. A blockchain technology is a tamper proof and secure technology which make the technology suitable for data store. However, there are some question from the critics with the issues related to technical challenges like the storage space of blockchain and some security issues but the technology has shown the benefit in multiple sectors. Electronic Health Records (EHR), Electronic Medical Record (EMR), Patient Health Record (PHR) are the patients record that are need to be monitored continuously after the patient get discharged from the hospital specially the patients with heart diseases or cancer. The electronic medical record proves to be a great help for the patient and for the concerned doctor as well. These medical records need more security and privacy against the leak or misuse by some other person. There have been some incidents where it has seen the security breach in the electronic medical records of a patient. In order to provide privacy to these records blockchain technology can be beneficial. In this paper, we will provide a comprehensive survey of different methods for preserving the privacy of EMR using the blockchain technology.
