Skipped Zonal based Binary DCT (SZBinDCT) for Image communication over Resource Constrained Visual Sensor Network

10.11591/ijeecs.v7.i3.pp893-898
G. Suseela , Asnath Victy Phamila Y
The contemporary advancements in CMOS technology and Multimedia systems enabled image communication over resource constrained Visual Sensor Network (VSN). However, the size of image data is huge. It is wise to send the compressed image over the bandwidth limited network. Compression algorithms also should be of energy efficient with low complexity and should offer acceptable image quality. In this work an image coder offering low bit rate less than 0.5bpp is aimed. In this paper, a low memory and energy efficient skipped zonal based Binary DCT is proposed that codes the transformed samples using Golomb Rice code. Simulation results offered low bitrate 0.39 bpp with PSNR of 27.34 dB for the standard gray scale test image of Lena size 512 x512 pixels.

Three tapered baluns with nonlinear transition are developed for harmonic suppression in dipole antenna. The first balun consists of an exponential profile with the size of a quarter–wavelength for both the height and width with a wideband characteristic. However, for some applications such as narrowband harmonic suppression antennas and wideband-to-narrowband reconfigurable antennas, the suppression of higher operating band is desired. By employing stubs-filter and a defected ground structure (DGS), two narrowband tapered baluns are produced. They are named as an exponential balun-stub and an exponential balun-DGS, respectively, that operate from 1 to 2 GHz. A simulated and measured results that based on the reflection coefficient is found to be better than -10 dB from 1 to 2 GHz. The employment of the stubs and DGS have enabled these baluns to have the capability to reject the unwanted higher frequency band from 2.0 to 10 GHz. Finally, the proposed baluns are employed as a feeding circuit for an ultra wideband (UWB) circular dipole antenna that produces a reasonable outcome.

10.11591/ijeecs.v7.i3.pp809-817
Kottalanka Srikanth , D. Arivazhagan
There has been increasing demand in improving service provisioning in hospital resources management. Hospital industries work with strict budget constraint at the same time assures quality care. To achieve quality care with budget constraint an efficient prediction model is required. Recently there has been various time series based prediction model has been proposed to manage hospital resources such ambulance monitoring, emergency care and so on.  These models are not efficient as they do not consider the nature of scenario such climate condition etc. To address this artificial intelligence is adopted. The issues with existing prediction are that the training suffers from local optima error.  This induces overhead and affects the accuracy in prediction. To overcome the local minima error, this work presents a patient inflow prediction model by adopting resilient backpropagation neural network. Experiment are conducted to evaluate the performance of proposed model inter of RMSE and MAPE. The outcome shows the proposed model reduces RMSE and MAPE over existing back propagation based artificial neural network. The overall outcomes show the proposed prediction model improves the accuracy of prediction which aid in improving the quality of health care management.

Medi Yarmen
This research aims to investigate the simultaneous effect of satisfaction, perceived value, image, and perceived sacrifice on patient loyalty. This study is believed to be the first to develop and test patient loyalty model that includes satisfaction, perceived value, image, and perceived sacrifice. Quantitative research methodology was employed. We performed survey to collect the empirical data. The respondents are 162 patients of two health care service institutions in Bogor and Bekasi, Indonesia. The conceptual model and proposed hypotheses were examined using multiple regressions analysis. The findings showed that image has positive impact on patient loyalty. However, this research also found that satisfaction, perceived value, and perceived sacrifice do not have significant impact on patient loyalty. Thus, the management of public healthcare service institution should consider and manage the image of the institution proactively.

Dengue Haemorrhagic Fever (DHF) prevention and control program has been conducted in Kupang City but DHF Incidence Rate (IR) is always high and exceeds the national average. Calculating the density of larvae and pupae is a good choice in calculating DHF mosquitos’ density because larvae capture is easier than mosquitoes, and pupa is the nearest stage with adult mosquitoes so can better represent actual mosquito density. This observational study used cross sectional study design was conducted in Kupang City as many 24 urban villages or 480 houses during the rainy and dry season and all containers inside and outside homes selected been observed. Larvae and pupae were collected using gamadotik then identified. Analyzed data were using multiple regression logistic test, independent t test and Anova test. This study found 781 containers with the equation model of container positivity = 2,975 lid - 0.192 material + 0.781 type - 3,706, with the most influential variable is the container lid (OR 19.5). Ae. Aegypti, Ae. Albopictus and Culex can be found in water containers both inside and outside homes. The presence of larvae can be prevented either by doing closed and drain the container regularly and bury or drying container that is not used anymore. As limitation of water supply so other solutions need to be taken such as by sprinkling temefos into container with closed tightly to reduce the container positivity 19.5 times. For greater container can be done by water draining or reuse used container outside the home into a place to plant flowers or plants or become temporary garbage.

Susmita Kar , Md. Kapil Ahmed
Detection of the cervical cancer requires practice of screening that will increase survival rates from the disease. Visual Inspection with Acetic Acid (VIA) is an alternative to screening for cervical cancer.This study aims to assess the knowledge, attitude, and practice towards VIA screening among adult women. We used a cross-sectional study in urban areas of Bangladesh with a sample of 285 respondents those were interviewed through semi-structured questionnaire. Analyses have done by targeting the objectives and considering the indicators with appropriate test statsitsics.About 56.1% respondents aged between 18 and 35 years with majority had at least secondary education including 29.5% were from affluent group. Though the highest majority of women had the knowledge of cervical cancer but only quarter was aware of VIA. A few of the respondents adopted any screening test for detecting cervical cancer and this lower coverage could be due to, among other reasons, lack of knowledge, accessibility, and service availability. The results also indicated that higher educational level of respondents is the predictor of improving knowledge on the disease and early adoption of available test procedure.An awareness building program should be designed for women of early detection of cervical cancer using VIA procedure.

In recent years, the use of cloud services has been significantly expanded. The providers of software as a service employ multi-tenant architectures to deliver services to their users. In these multi-tenant applications the resource allocation would suffer from over-utilization or under-utilization issues. Considering the significant effects of resource allocation on the service performance and cost, in this paper we have proposed an approach based on genetic algorithm for resource allocation which guarantees service quality through providing adequate resources. The proposed approach also improves system performance, meets the requirements of users and provides maximum resource efficiency. Simulation results show that the proposed approach has better response rate and availability comparing to other approaches, while provides an efficient resource usage.
